And a manual operation position is arranged at the position, close to the second conveying mechanism 2, of the third conveying mechanism 5, and when the cylinder body and the cylinder cover which are installed on the second conveying mechanism 2 are conveyed to the downstream of the third conveying mechanism 5, a worker takes out a workpiece from the camshaft box A1 and places the workpiece on the cylinder cover. The first conveying roller group 52 is used for conveying the camshaft box A1 with the workpiece, and the second conveying roller group 55 is used for conveying the empty camshaft box A1. After taking out the workpiece, the worker moves the empty camshaft box A1 from the first conveying roller group 52 to the second conveying roller group 55, the second conveying roller group 55 conveys the empty camshaft box A1 to the second lifter 61, and the empty camshaft box A1 is lifted to the second position by the second lifting mechanism 6. After the empty camshaft box A1 raised to the second position is moved by the camshaft transfer mechanism and exchanged with the camshaft box A1 with the workpiece at the first position, the camshaft box A1 with the workpiece is lowered from the second position to the first conveying roller group 52, and the material is fed by the first conveying roller group 52. Through setting up fixture 4 for the cylinder cap realizes automatic installation. The first conveying roller group 52 is continuously supplemented with the camshaft box A1 with the workpieces, the second conveying roller group 55 is continuously discharged with the empty camshaft box A1, the camshaft box A1 is circulated through the first conveying roller group 52 and the second conveying roller group 55, the utilization rate of the camshaft box A1 is improved, and the number of the camshaft boxes A1 is small. Meanwhile, the cylinder cover and the camshaft box A1 provided with the workpiece are simultaneously conveyed through the first conveying mechanism 1, so that required conveying equipment is reduced. Meanwhile, the conveying speed of the camshaft box A1 with the workpiece is matched with the conveying speed of the cylinder body on the second conveying member mechanism, when the cylinder body is conveyed to the third conveying mechanism 5, the camshaft box A1 with the workpiece is conveyed to the downstream of the second conveying mechanism 2, a worker can conveniently and quickly install the workpiece on the cylinder body, and the assembling efficiency of the engine is greatly improved.

Specifically, the camshaft box A1 with the work pieces lowered by the second lifting mechanism 6 is conveyed to the manual operation position by the first conveying roller group 52, so that the work pieces can be conveniently loaded by the worker.

It should be understood that the second conveying mechanism 2 is an existing production line, and in order to adapt to the field space and not change the conveying speed of the existing second conveying mechanism 2 (match the conveying speed of the second conveying mechanism 2), the first lifting mechanism 3 and the second lifting mechanism 6 are arranged on the feeding production line for engine assembly, and the camshaft transfer mechanism is arranged above the first lifting mechanism 3 and the second lifting mechanism 6.

Specifically, the camshaft transfer mechanism includes a first transfer rail 71, a second transfer rail 72, a first mount 73, a first linear actuator 74, a second linear actuator 75, a first clamp 76, and a second clamp 77. The first transfer rail 71 is mounted to the first frame, the first transfer rail 71 extends in a direction in which the first lifting mechanism 3 and the second lifting mechanism 6 are coupled, the second transfer rail 72 is perpendicular to the first transfer rail 71, and the second transfer rail 72 is slidably coupled to the first transfer rail 71, and the first mounting seat 73 is slidably coupled to the second transfer rail 72. The first clamping member 76 and the second clamping member 77 are used for clamping the camshaft box A1, the first clamping member 76 is installed at the output end of the first linear driver 74, the second clamping member 77 is installed at the output end of the first linear driver 75 of the first installation seat 73, and the first linear driver 74 and the second linear driver 75 are installed at the first installation seat 73. Under the guidance of the first conveying rail 71 and the second conveying rail 72, the first mounting seat 73 can slide to an arbitrary position in the plane, and the first clamping member 76 and the second clamping member 77 can clamp the camshaft case A1 at the arbitrary position in the plane.

It can be understood that a driving member is disposed on each of the first conveying rail 71 and the second conveying rail 72, the driving member on the first conveying rail 71 is used for driving the second conveying rail 72 to slide on the first conveying rail 71, and the driving member on the second conveying rail 72 is used for driving the first mounting seat 73 to slide on the second conveying rail 72. The driving member is provided as a conventional means in the art, and therefore, will not be described herein.

Alternatively, in an embodiment of the present invention, the first linear driver 74 may be one of a linear motor, an air cylinder, and a screw structure.

For programming convenience, the height of the first location and the height of the second location are typically set the same.

Since the heights at the first and second positions are constant, i.e., the length of the first linear actuator 74 that needs to be extended each time is the same, the linear motor, screw structure is slow when driving the first clamping member 76 downward, and the long-term reciprocating motion is prone to malfunction and maintenance is troublesome.

Preferably, in an embodiment of the present invention, the first linear actuator 74 is a cylinder, which has a simple structure, can be well adapted to the up-and-down reciprocating motion, and is easy to maintain.

Alternatively, in an embodiment of the present invention, the second linear actuator 75 may be one of a linear motor, an air cylinder, and a screw structure.

Since the heights at the first and second positions are constant, i.e., the length of the second linear actuator 75 that needs to be extended each time is the same, the linear motor and screw structure is slow when driving the second clamping member 77 to move downward, and the long-term reciprocating motion is prone to failure and troublesome to maintain.

Preferably, in an embodiment of the present invention, the second linear actuator 75 is a cylinder, which has a simple structure, can be well adapted to the up-and-down reciprocating motion, and is easy to maintain.

It can be understood that the first installation seat 73 is initially located above the second position, when the cam transfer mechanism 7 operates, the second linear actuator 75 drives the second clamping member 77 to move downward, the second clamping member 77 clamps the empty camshaft box A1 at the second position and then the second linear actuator 75 is reset, and then the second conveying rail 72 moves to above the first position along the first conveying rail 71, and the first installation seat 73 slides along the second conveying rail 72 until the first clamping member 76 moves to just above the camshaft box A1 with the workpiece. The first linear actuator 74 drives the first clamping member 76 to move downward, and the first linear actuator 74 is reset after clamping the camshaft box A1 with the workpiece. The first mounting seat 73 is moved again so that the second clamping member 77 is aligned with the first position, the second linear actuator 75 drives the second clamping member 77 downward, and the second linear actuator 75 is reset after the second clamping member 77 places the empty camshaft cartridge A1 at the first position. Then, the second transfer rail 72 is moved to the initial position, and the first clamping member 76 is moved downward by the first linear actuator 74 to place the camshaft magazine A1 with the workpieces therein at the first position.

After the exchange of the camshaft box A1 at the first position is completed, the first lifting mechanism 3 drives the empty camshaft box A1 to move downwards to the side of the first conveying mechanism 1, the empty camshaft box A1 penetrates out, the first conveying mechanism 1 conveys the camshaft box A1 with the workpiece to the first lifting mechanism 3 again, and the first lifting mechanism 3 lifts the camshaft box A1 with the workpiece to the first position.

After the exchange of the camshaft box A1 at the second position is completed, the second lifting mechanism 6 drives the camshaft box A1 with the workpiece to move downwards to the upstream of the third conveying mechanism 5, the first conveying roller set 52 penetrates out the camshaft box A1 with the workpiece, the second conveying roller set 55 conveys the camshaft box A1 with the workpiece to the second lifting mechanism 6 again, and the second lifting mechanism 6 lifts the empty camshaft box A1 to the second position.

It should be understood that the camshaft magazine A1 with the workpiece on the first conveying roller group 52 should be transferred to the second conveying roller group 55 after the workpiece is removed, to realize the circulation of the camshaft magazine A1.

Since the first conveying roller group 52 and the second conveying roller group 55 are juxtaposed, the balls 511 are provided on the conveying frames 51 on the side of both the first conveying roller group 52 and the second conveying roller group 55 close to the second conveying mechanism 2 (the end of the first conveying roller group 52 and the start of the second conveying roller group 55), and the balls 511 are provided between the first conveying roller group 52 and the second conveying roller group 55.

After the operator takes out the camshaft in the camshaft box A1, the operator pushes the camshaft box A1 of the taken-out camshaft on the first conveying roller group 52, so that the camshaft box A1 moves laterally and moves to the second conveying roller group 55 under the rolling of the balls 511.

Preferably, in an embodiment of the present invention, in order that the first and second conveying roller groups 52 and 55 can convey the camshaft box A1 in cooperation with the second lifting mechanism 6 after the camshaft box A1 on the first conveying roller group 52 is moved, third stroke switches 521 are provided on both the first and second conveying roller groups 52 and 55.

When the empty camshaft box A1 on the first conveying roller group 52 moves to the second conveying roller group 55, the third travel switch 521 on the first conveying roller group 52 is no longer triggered, at this time, the controller 9 controls the first conveying roller group 52 to convey the camshaft box A1 with the workpiece forward, the camshaft box A1 with the workpiece triggers the third travel switch 521 on the first conveying roller group 52 again, and the first conveying roller group 52 stops conveying, so that the first conveying roller group 52 can be timely loaded.

When the third stroke switch 521 on the second conveying roller group 55 is triggered after the empty camshaft case A1 on the first conveying roller group 52 moves to the second conveying roller group 55, the controller 9 controls the second conveying roller group 55 to convey the empty camshaft case A1 forward until the third stroke switch 521 on the second conveying roller group 55 is not triggered any more.

It is to be understood that the third stroke switch 521 on the first conveying roller group 52 is provided at the end of the first conveying roller group 52 near the second conveying mechanism 2; the third stroke switch 521 on the second conveying roller group 55 is provided on the side of the second conveying roller group 55 close to the second conveyor mechanism, and the distance of the third stroke switch 521 on the second conveying roller group 55 from the end of the second conveying roller group 55 matches the length of one camshaft case A1.

Specifically, the first and second holding

members

76 and 77 are identical in structure.

Preferably, in an embodiment of the present invention, the first clamping member 76 includes a bidirectional cylinder 761 and a clamping rod 762, the bidirectional cylinder 761 is installed at an output end of the first linear actuator 74, and the clamping rod 762 is fixedly connected to an output end of the bidirectional cylinder 761. When the bidirectional cylinder 761 contracts, the two opposite clamping rods 762 approach each other, so as to clamp the camshaft box A1.

The first clamping piece 76 can also adopt structures such as a clamping jaw 42, but the structures such as the clamping jaw 42 are complex, the maintenance is complex, and the structure of the bidirectional cylinder 761 is relatively simple and convenient to maintain.

Further, in an embodiment of the present invention, in order to make the clamping of the camshaft box A1 more stable, the bidirectional cylinder 761 is usually a dual-shaft bidirectional cylinder 761, and the contact area between the clamping rod 762 and the camshaft box A1 is larger, so that the clamping of the camshaft box A1 is more stable.

Specifically, the gripping mechanism 4 includes a robot 41 and a gripper 42, and the gripper 42 is attached to the robot 41. The clamping jaw 42 includes a second mounting seat 421, a third linear actuator 422, a first clamping rod 423 and a second clamping rod 424. The third linear actuator 422 is mounted on the second mounting seat 421, the first clamping rod 423 is fixedly connected to the second mounting seat 421, the second clamping rod 424 is relatively disposed beside the first clamping rod 423, a certain gap 424 is formed between the first clamping rod 423 and the second clamping rod 424, and the second clamping rod 424 is fixedly connected to the output end of the third linear actuator 422 and driven by the third linear actuator 422 to move up and down. The second gripping rod 424 is provided at a lower portion thereof with a slope 4241, the slope 4241 is disposed below the first gripping rod 423, and when the third linear actuator 422 drives the second gripping rod 424 to ascend, the slope 4241 abuts the first gripping rod 423. When clamping jaw 42 centre gripping cylinder cap, first supporting rod 423 and second supporting rod 424 all insert to same through-hole in, third linear actuator 422 drive second supporting rod 424 rises this moment, and second supporting rod 424 rises and drives slope 4241 and rises, and then makes the clearance 424 increase between first supporting rod 423 and the second supporting rod 424, and then presss from both sides tight cylinder cap, avoids the cylinder cap slippage.

It will be appreciated that the ramp 4241 is located within or below the through bore of the cylinder head. When slope 4241 is located the cylinder cap through-hole, first clamping rod 423 and second clamping rod 424 butt a chucking through-hole, guarantee that clamping jaw 42 can stabilize the centre gripping cylinder cap. When the slope 4241 is located below the cylinder cover through hole, the first clamping rod 423 and the second clamping rod 424 above the slope 4241 are still located in the through hole, and the cross-sectional area surrounded by the first clamping rod 423 and the second clamping rod 424 at the slope 4241 is larger than that of the through hole, so that the cylinder cover is well clamped by the clamping jaw 42 and cannot slip off.

Alternatively, in an embodiment of the present invention, the first clamping rod 423 and the second clamping rod 424 may be one of a square rod, a round rod, or other polygonal rods.

Preferably, in an embodiment of the present invention, in order to better fit the inner wall of the cylinder head through hole, the first clamping rod 423 and the second clamping rod 424 are both semi-cylindrical rods. The side planes (the semi-cylindrical rod side planes comprise a plane and a curved surface, and the plane part is called as the side plane) of the first clamping rod 423 and the second clamping rod 424 are arranged oppositely, the shape of the first clamping rod 423 and the second clamping rod 424 after combination is matched with the shape of the through hole, the contact area of the first clamping rod 423 and the second clamping rod 424 with the inner wall of the through hole of the cylinder cover is larger, and the cylinder cover can be clamped more stably.

When clamping jaw 42 downstream so that first clamping rod 423 and second clamping rod 424 get into the cylinder cap through-hole, the bottom of first clamping rod 423 and second clamping rod 424 first contacts with the upper portion of cylinder cap, and first clamping rod 423 and second clamping rod 424 bottom surface are the plane, if there is slight error in the location this moment, clamping jaw 42 down the in-process can not make first clamping rod 423 and second clamping rod 424 get into to the cylinder cap through-hole smoothly.

Preferably, in an embodiment of the present invention, in order to smoothly enter the first clamping rod 423 and the second clamping rod 424 into the through hole, a bottom surface of the first clamping rod 423 protrudes downward to form a first smooth curved surface 4231, and the first smooth curved surface 4231 is tangent to a side curved surface of the first clamping rod 423; the bottom surface of the second clamping bar 424 is downwardly convex to form a second smooth curved surface 4242, and the second smooth curved surface 4242 is tangent to the side curved surface of the second clamping bar 424. When the clamping jaw 42 has a slight error in positioning, the clamped cylinder cover is squeezed to displace, so that the first clamping rod 423 and the second clamping rod 424 are smoothly inserted into the through hole of the cylinder cover.

It is understood that the slope 4241 may be provided at any position of the second clamping bar 424 under the first clamping bar 423.

Preferably, in an embodiment of the present invention, in order to facilitate the processing of the second clamping bar 424, a ramp 4241 is provided at a lower portion of the second clamping bar 424, and the lower portion of the ramp 4241 is connected with a second smoothly curved surface 4242.

Alternatively, in an embodiment of the present invention, the third linear actuator 422 is used to drive the first clamping rod 423 to move up and down, and the third linear actuator 422 may be one of a screw rod, a push rod motor, a linear motor, an air cylinder, and a hydraulic cylinder.

Preferably, in an embodiment of the present invention, the third linear actuator 422 is a cylinder, which has a simple structure and is easy to maintain.

It can be understood that the clamping jaw 42 lifts the second clamping rod 424 when clamping the cylinder cover, and pushes the second clamping rod 424 to reset when clamping the cylinder cover.

Further, the clamping mechanism 4 further includes a sleeve 426, the sleeve 426 is fixedly connected to the second mounting seat 421, the output end of the third linear actuator 422 is disposed in the inner cavity of the sleeve 426, the first clamping rod 423 is fixedly connected to the inner wall of the sleeve 426, the first clamping rod 423 extends downward through the sleeve 426, and the second clamping rod 424 is disposed in the inner cavity of the sleeve 426 and extends downward through the sleeve 426. The inner cavity of the sleeve 426 is provided with a first spring 4261, one end of the first spring 4261 is fixedly connected with the sleeve 426, and the other end abuts against the second clamping rod 424. When the cylinder moves the second clamping rod 424 up, the first spring 4261 is compressed. After placing the cylinder head, the second clamping bar 424 needs to be repositioned to separate the clamping jaw 42 from the cylinder head. The compressed spring drives the second clamping rod 424 to reset, so that the air cylinder does not need to do driving action, and energy is saved.

The cylinder head is usually provided with a plurality of through holes, and the through holes are generally arranged at four corners and other positions of the cylinder head.

Preferably, in an embodiment of the present invention, the clamping jaw 42 is provided with at least two pairs of first clamping rods 423 and second clamping rods 424 to clamp opposite corners of the cylinder head, so that the clamping is relatively stable.

More preferably, in an embodiment of the present invention, the first clamping rod 423 and the second clamping rod 424 are provided with four pairs, and the four pairs of the first clamping rod 423 and the second clamping rod 424 correspond to four corners of the cylinder head, respectively, so that the cylinder head is clamped stably.

It will be appreciated that five-axis manipulators 41 are typically used for the manipulator 41, and that multiple degrees of freedom enable the manipulator 41 to grasp the cylinder heads at various locations. The robot 41 is provided with a sensor which is in communication with the controller 9. The sensor senses the relative position of the clamping jaw 42 and the cylinder cover, so that the controller 9 controls the clamping jaw 42 to accurately clamp the cylinder cover.

Specifically, the wiping mechanism 8 includes a tension frame 81, a take-up roller 82, a placement roller 83, and a motor 88. The tensioning frame 81 is used for tensioning the wiping paper 88, the winding roller 82 is used for winding the wiping paper 88, the placing roller 83 is used for placing the wiping paper 88, and the winding roller 82 and the placing roller 83 are both rotatably connected to the tensioning frame 81. The motor 88 is mounted to the tensioning bracket 81 and the motor 88 is in driving connection with the take-up roller 82. The tensioning frame 81 tensions the wiping paper 88 connected with the winding roller 82 and the placing roller 83, the placing roller 83 and the winding roller 82 synchronously rotate under the driving of the wiping paper 88 and the constraint of the tensioning frame 81, and the wiping paper 88 always keeps a flat state in the cylinder cover wiping process, so that the cylinder cover wiping oil removal effect is good.

The tensioning frame 81 provided by the invention comprises a second frame 811, a first roller 812 and a first connecting block 813, and a second roller 818 and a second connecting block 815. The first roller 812 is rotatably connected with the first connecting block 813, the second roller 818 is rotatably connected with the second connecting block 815, the first connecting block 813 is fixedly connected with the second frame 811, and the second connecting block 815 is fixedly connected with the second frame 811. The wiping paper 88 and the winding roller 82 are respectively arranged on two sides of the second frame 811, so that the wiping paper 88 can be matched with the first roller 812 and the second roller 818 to realize the flat and tension of the wiping paper 88 (the wiping paper 88 passes through the gap 424 between the first roller 812 and the second roller 818 from the lower part of the second roller 818 and then spans the first roller 812 to be connected with the winding roller 82), and the cylinder cover wiping efficiency is improved.

If the first connecting block 813 is fixedly connected with the second frame 811, the cylinder cover is directly pressed down onto the first roller 812 if a fault occurs, and the wiping paper 88 is pressed to generate a large friction, which is easily broken under the pulling force of winding.

Therefore, the first connecting block 813 is slidably connected to the second housing 811 and is provided with a first elastic member 816, and the first elastic member 816 is mounted to the second housing 811 to provide an upward force to the first connecting block 813. If the cylinder cover is pressed down directly, the friction force applied to the paper wiping 88 will not increase to the maximum during the deformation process of the first elastic member 816, but has a certain buffer, and at this time, the worker has enough reaction time to lift the cylinder cover, so as to avoid the paper wiping 88 from breaking.

It can be understood that the second connecting block 815 is fixedly or slidably connected to the second housing 811 while the first connecting block 813 is slidably connected to the second housing 811.

When the second connecting block 815 is fixedly connected with the second frame 811, if the first roller 812 moves downward under the pressure of the cylinder cover, the distance between the first roller 812 and the second roller 818 is reduced, and the wiping paper 88 is still the original length, at this time, the wiping paper 88 is prone to wrinkle.

When the second connecting block 815 is slidably connected to the second frame 811, the second roller 818 pulls down the wiping paper 88 by its own weight, but since the second connecting block 815 has no other constraint, the sliding state of the second connecting block 815 is easily changed (e.g., a force is easily applied to move upward to break the tension state of the wiping paper 88). A second elastic member 817 is further provided, and the second elastic member 817 is mounted to the second housing 811 to provide a downward force to the second connecting block 815. Under the constraint of the second elastic member 817, the second roller 818 is not easy to change position when being stressed, and can tension the wiping paper 88 more stably.

In summary, the tensioning frame 81 provided by the present invention includes a second frame 811, a first roller 812 and a first connecting block 813, a second roller 818 and a second connecting block 815, a first elastic member 816 and a second elastic member 817. The first roller 812 is rotatably connected to a first connecting block 813, and the first connecting block 813 is slidably connected to the second frame 811. The second roller 818 is rotatably connected to a second connecting block 815, and the second connecting block 815 is slidably connected to the second housing 811. The first elastic member 816 is installed to the second housing 811 to provide an upward force to the first coupling block 813. A second elastic member 817 is installed at the second housing 811 to provide a downward force to the second connecting block 815. The upward force provided by the first resilient member 816 is greater than the downward force provided by the second resilient member 817. When wiping is needed, the wiping paper 88 is wound on the tensioning frame 81, the wiping paper 88 is wound from the lower surface of the second roller 818 to the upper surface of the first roller 812, one side of the released wiping paper 88 is positioned above the line connecting the second roller 818 and the first roller 812, and the position for winding the wiping paper 88 is positioned below the first roller 812. When a worker moves the cylinder cover to the upper surface of the first roller 812 for wiping, the first roller 812 moves downwards, the upward force of the first elastic member 816 on the first connecting block 813 is increased, the first roller 812 does not pull the second roller 818 upwards through the wiping paper 88, and when the second roller 818 moves downwards for a certain distance under the downward force of the second elastic member 817, the first roller 812 pulls the second roller 818 through the wiping paper 88 again, so that the wiping paper 88 between the first roller 812 and the second roller 818 is kept tensioned. At this time, the wiping paper 88 on the upper surface of the first roller 812 is always in a tensioned state, and the worker can quickly wipe the cylinder cover by only horizontally moving the cylinder cover.

Specifically, in an embodiment of the present invention, the second housing 811 is provided with a first long hole 818 and a second long hole 819, and the second long hole 819 is located below the first long hole 818. The first connecting block 813 is slidably coupled within the first slot 818 and the second connecting block 815 is positioned within the second slot 819.

In use, the paper wiper 88 is inserted into the gap 424 between the first roller 812 and the second roller 818 from below the second roller 818, abuts against the upper surface of the first roller 812, and is then wound around the take-up roller 82. The first elastic member 816 provides an upward force to the wiping paper 88, and the second elastic member 817 provides a downward force to the wiping paper 88, thereby tensioning the wiping paper 88 between the first roller 812 and the second roller 818 for wiping the cylinder cover.

If the downward force provided by the second elastic member 817 is greater than the upward force of the first elastic member 816, the downward force transmitted to the first elastic member 816 by the force of the second elastic member 817 through the second roller 818, the wiping paper 88 and the first roller 812 easily causes the first elastic member 816 to compress downward, the second elastic member 817 drives the second connecting block 815 to bottom in the second slot 819, the first roller 812 is pulled downward, and the first roller 812 and the second roller 818 are farthest away. If the cylinder cover presses the first roller 812, the first roller 812 moves downwards, so that the distance between the first roller 812 and the second roller 818 is reduced, the length of the paper wiping 88 is unchanged, and the paper wiping 88 is wrinkled.

Therefore, in this embodiment, the upward force provided by the first elastic member 816 is configured to be greater than or equal to the downward force provided by the second elastic member 817, so as to eliminate the adverse effect of the downward force generated by the second elastic member 817 on the first elastic member 816, and at the same time, to better ensure that the first roller 812 and the second roller 818 can tension the wiping paper 88 at any time. Ideally, the first elastic member 816 supports the first roller 812 in contact with the top surface of the first long hole 818, and the second elastic member 817 supports the second roller 818 in contact with the top surface of the second long hole 819, so that the wiping paper 88 can be stably tensioned while ensuring the cushioning capacity of the first elastic member 816.

Alternatively, in an embodiment of the present invention, the first elastic member 816 and the second elastic member 817 may be disposed above the first long hole 818 and the second long hole 819, respectively. The positions of the first connecting block 813 and the second connecting block 815 determine the positions of the first roller 812 and the second roller 818, and if the first elastic member 816 is disposed above the first long hole 818, the second elastic member 817 is disposed above the second long hole 819, and at this time, the second frame 811 needs to extend upward to meet the installation requirement of the first elastic member 816.

However, when the first elastic member 816 is installed above the first connecting block 813, the upper surface of the second frame 811 is higher than the upper surface of the roller, and at this time, the cylinder head may collide with the second frame 811 during the wiping process.

It will be appreciated that the upper surface of the first roller 812 should be higher than the upper surface of the second frame 811 or flush with the upper surface of the second frame 811 so that the cylinder head does not hit the second frame 811 during the wiping process.

Preferably, in an embodiment of the present invention, in order to prevent the cylinder head from colliding with the second frame 811, the first elastic member 816 is disposed below the first connecting block 813. In the initial state, the first elastic member 816 is under compression, so as to provide an upward pushing force to the first connecting block 813, so that the first connecting block 813 is located on the top of the first long hole 818.

Alternatively, in an embodiment of the present invention, since the second long hole 819 is disposed below the first long hole 818, the second elastic member 817 may be installed above or below the second connection block 815.

When the second elastic member 817 is installed below the second connection block 815, the second elastic member 817 is initially in a stretched state, but the tension of the second elastic member 817 is smaller than that of the first elastic member 816, so that when the first elastic member 816 pulls the wiping paper 88, the second connection block 815 is pulled to the top of the inner wall of the second long hole 819.

When the first connecting block 813 moves downwards, the second roller 818 is no longer pulled upwards by the wiping paper 88 between the first connecting block 813 and the second connecting block, and then the second roller 818 moves downwards under the action of the pulling force of the second elastic member 817, so that the wiping paper 88 is tensioned again, and the wiping effect is good.

When the second elastic member 817 is installed above the second connection block 815, the second elastic member 817 is initially in a compressed state, but the pushing force of the second elastic member 817 is smaller than the pulling force of the first elastic member 816, so that when the first elastic member 816 pulls the paper wipe 88, the second connection block 815 is pulled to the top of the second long hole 819.

When the first connecting block 813 moves downwards, the wiping paper 88 between the two blocks no longer pulls the second roller 818 upwards, and then the second roller 818 moves downwards under the pushing force of the second elastic member 817, so that the wiping paper 88 is tensioned again, and the wiping effect is good.

Alternatively, in an embodiment of the present invention, the first elastic member 816 may be one of a compression spring and a torsion spring, the second elastic member 817 may be one of a compression spring and a torsion spring when being disposed above the second long hole 819, and the second elastic member 817 may be a tension spring when being disposed below the second long hole 819. If the first elastic member 816 or the second elastic member 817 is directly and fixedly connected to the second housing 811, it is difficult to repair and replace the second housing.

Preferably, in an embodiment of the present invention, the first elastic member 816 includes a third mounting seat 8161, a first connecting rod 8162 and a third spring 8173, the third mounting seat 8161 is fixedly connected to the second frame 811, one end of the first connecting rod 8162 is fixedly connected to the first connecting block 813, the first connecting rod 8162 extends downward through the third mounting seat 8161, the first connecting rod 8162 and the third mounting seat 8161 are slidably connected, one end of the third spring 8173 is connected to the upper surface of the third mounting seat 8161, and the other end of the third spring 8173 is connected to one end of the first connecting rod 8162.

For ease of replacement and maintenance, the third spring 8173 generally abuts the third mount 8161 and the first connecting rod 8162.

In order to fix the first connection rod 8162 conveniently, a through hole is formed in the first connection block 813, the first connection rod 8162 penetrates through the through hole, and two nuts 8168 are arranged on the first connection rod 8162, the two nuts 8168 are respectively arranged above and below the through hole, so that the first connection rod 8162 and the first connection block 813 are fixed. The third spring 8173 abuts against the lower surface of the lower nut 8168.

It should be noted that the lower diameter of the first connecting rod 8162 (the lower diameter is larger than the rod diameter above the bottom) is enlarged to avoid the first connecting rod 8162 from sliding out of the third mounting seat 8161.

Preferably, in an embodiment of the present invention, the second elastic member 817 includes a fourth mounting seat 8171, a second connecting rod 8172 and a third spring 8173, the fourth mounting seat 8171 is fixedly connected to the second frame 811, one end of the second connecting rod 8172 is fixedly connected to the second connecting block 815, the second connecting rod 8172 extends downward through the fourth mounting seat 8171, the second connecting rod 8172 is slidably connected to the fourth mounting seat 8171, one end of the third spring 8173 is connected to a bottom surface of the third mounting seat 8161, and the other end of the third spring 8173 is connected to one end of the second connecting rod 8172.

For ease of replacement and maintenance, the third spring 8173 generally abuts the fourth mount 8171 and the second connecting rod 8172.

In order to fix the second connection rod 8172 conveniently, a through hole is formed in the second connection block 815, the second connection rod 8172 penetrates through the through hole, and two nuts 8168 are arranged on the second connection rod 8172, the two nuts 8168 are respectively arranged above and below the through hole, so that the second connection rod 8172 and the second connection block 815 are fixed.

It should be noted that the diameter of the lower portion of the second connecting rod 8172 is increased to prevent the second connecting rod 8172 from sliding out of the fourth mounting seat 8171. One end of the third spring 8173 abuts against the bottom surface of the fourth mounting seat 8171, and the other end abuts against the lower portion of the second rod.

The third mounting seat 8161 or the fourth mounting seat 8171 is fixedly connected with the second rack 811 through bolts, and the mounting and the dismounting are convenient.

Specifically, the placing roller 83 is disposed above a connecting line between the first roller 812 and the second roller 818, and the winding roller 82 is disposed below the first roller 812. The motor 88 is arranged on the second frame 811, the output end of the motor 88 is in transmission connection with the take-up roller 82, and the take-up roller 82 and the placing roller 83 synchronously rotate in the transmission connection of the wiping paper 88.

It will be appreciated that if the take-up roll 82 is positioned above the first roller 812, the tensioning bracket 81 will not be tensioned. If the placement roller 83 is disposed below the line connecting the first roller 812 and the second roller 818, the tension bracket 81 similarly cannot be tensioned.

Preferably, in an embodiment of the present invention, in order to enable the take-up roller 82 to be at any position, the tensioning frame 81 can play a role of tensioning the wiping paper 88, and a third roller 85 rotatably connected with the second frame 811 is further provided. The third drum is disposed between the first drum 812 and the take-up roll 82, and the third drum 85 is disposed below the first drum 812. At this time, no matter the take-up roller 82 is disposed above or below the first drum 812, the tension frame 81 can tension the wiping paper 88, so that the wiping effect is good.

Preferably, in an embodiment of the present invention, in order to enable the tension frame 81 to play a role of tensioning the wiping paper 88 when the placing roller 83 is at any position, a fourth roller 86 and a fifth roller 87 are further provided, which are rotatably connected with the second frame 811.

If the cylinder cover directly conveys on first drive mechanism 1, the cylinder cover can appear wearing and tearing in the data send process to the relative position of cylinder cover and camshaft box A1 is difficult to fix.

Preferably, in an embodiment of the present invention, in order to avoid the cylinder head from wearing and the relative position of the cylinder block and the camshaft box A1, the cylinder head and the camshaft box A1 are placed on the tray A2 for conveying.

Specifically, the first lifting mechanism 3 and the second lifting mechanism 6 have the same structure.

The first lifting mechanism 3 includes a first lifter 31, a first placing plate 32 and a first roller table 321, the first lifter 31 is used for lifting the first placing plate 32, and the first placing plate 32 is used for placing the tray A2. Because first conveying mechanism 1 is when conveying tray A2, tray A2 can not rely on inertia directly to slide to first place on the board 32, so set up first roll table 321 on first place board 32, first roll table 321 is by motor drive, when tray A2 of camshaft box A1 and the cylinder cap that is equipped with the work piece was placed in first conveying mechanism 1 conveying, first roll table 321 begins to rotate simultaneously, the tray A2 conveying that will place camshaft box A1 and the cylinder cap that is equipped with the work piece is to first place on the board 32.

Because the third transport mechanism 5 can not rely on inertia to directly slide from the third transport mechanism 5 to the second placing plate 62 when transporting the empty camshaft box A1 to the second lifting mechanism 6, the second roller 621 is disposed on the second placing plate 62, the second roller 621 is driven by the motor, and when the third transport mechanism 5 transports the empty camshaft box A1, the second roller 621 starts to rotate at the same time to transport the empty camshaft box A1 to the second placing plate 62. Similarly, the second roller path 621 also carries the camshaft case A1 with the workpiece mounted thereon to the third transfer mechanism 5.

It can be understood that the first hoisting machine 31 and the second hoisting machine 61 are similar to the transmission structure of the elevator, and the first hoisting machine 31 and the second hoisting machine 61 are prior art and therefore are not described herein again.

Preferably, in an embodiment of the present invention, in order to enable the first roller table 321 to stop the conveyance when the pallet A2 is completely positioned on the first placing plate 32, a first stroke switch 322 is provided on the first placing plate 32. When the tray A2 completely moves to the first placing plate 32 (when the camshaft box A1 and the cylinder cover can be stably lifted), the first travel switch 322 is triggered, the first roller table 321 stops conveying, and the controller 9 controls the first lifter 31 to lift the first placing plate 32 to the first position.

Specifically, two first travel switches 322 are provided, and the two first travel switches 322 are provided along the conveying direction of the first conveying mechanism 1. When the tray A2 is conveyed from the first conveying mechanism 1 to the first roller way 321, that is, after the tray A2 completely leaves the first conveying mechanism 1, both the two first stroke switches 322 are triggered, and the first roller way 321 stops conveying. When the tray A2 is conveyed from the first roller way 321 to the first conveying mechanism 1, that is, after the tray A2 completely leaves the first placing plate 32, the two first stroke switches 322 are not triggered, and the first roller way 321 stops conveying.

Preferably, in an embodiment of the present invention, in order to enable the second roller table 621 to stop conveying when the camshaft box A1 is completely located on the second placing plate 62, a second stroke switch 622 is provided on the second placing plate 62. When the empty camshaft box A1 is completely moved to the second placing plate 62 (when the camshaft box A1 can be stably lifted), the second stroke switch 622 is triggered, and the second roller 621 stops transmitting, and the controller 9 controls the second lifter 61 to lift the second placing plate 62 to the second position.

Specifically, two second stroke switches 622 are provided, and the two second stroke switches 622 are provided along the conveying direction of the third conveying mechanism 5. When the empty camshaft box A1 is transferred from the third transfer mechanism 5 to the first roller table 321, that is, after the empty camshaft box A1 completely leaves the first transfer mechanism 1, both the two second stroke switches 622 are triggered, and the second roller table 621 stops transferring. When the camshaft box A1 with the workpiece is transferred from the second roller 621 to the third transfer mechanism 5, that is, after the camshaft box A1 with the workpiece completely leaves the second placing plate 62, both the second stroke switches 622 are not triggered, and the second roller 621 stops transferring.

Specifically, the first conveying mechanism 1 includes a third conveying roller group 11 and a fourth conveying roller group 12 driven by a motor, the conveying directions of the third conveying roller group 11 and the fourth conveying roller group 12 are opposite, and the third conveying roller group 11 and the fourth conveying roller group 12 each include at least two conveying rollers.

Alternatively, in an embodiment of the present invention, since the first conveyance mechanism 1 is used to circularly convey the camshaft box A1 filled with the work pieces to the empty camshaft box A1 (the camshaft box A1 is placed on the tray A2), the first conveyance mechanism 1 may be provided in the same conveyance structure of the third conveyance mechanism 5, that is, the third conveyance roller group 11 and the fourth conveyance roller group 12 are provided in parallel.

However, after the third conveying roller group 11 and the fourth conveying roller group 12 are arranged in parallel, the camshaft magazine A1 with workpieces mounted on the second placement plate 62 and the empty camshaft magazine A1 are located at different positions (corresponding to the positions of the third conveying roller group 11 and the fourth conveying roller group 12 is required), the time required for the movement of the cam transfer mechanism 7 becomes long (it is more time-saving and easier to program the cam transfer mechanism 7 to grip and place the camshaft magazine A1 at the same position), and the distance between the cam transfer mechanism 7 and the first lifting mechanism 3 needs to be newly determined to be adapted to the conveying speed of the second conveying mechanism 2.

And because camshaft box A1 is placed in tray A2, the width of two trays A2 will surpass the width of first hoist mechanism 3 opening, need change suitable hoist mechanism, and is comparatively troublesome.

Preferably, in an embodiment of the present invention, the third conveying roller group 11 is disposed above the fourth conveying roller group 12, and the conveying of the tray A2 is realized by lifting the first placing plate 32 to different heights (the first lifting mechanism 3 is used to lift the tray A2 at the third conveying roller group 11 where the camshaft box A1 with the work is placed to the first position, and the first lifting mechanism 3 is used to lower the tray A2 at the first position where the empty camshaft box A1 is placed to the fourth conveying roller group 12). The tray A2 on which the camshaft case A1 with the work is placed and the tray A2 on which the empty camshaft case A1 is placed are located at the same position of the first placing plate 32 during conveyance, so that the conveyance speed of the second conveyance mechanism 2 can be adapted to a case where the first conveyance mechanism 1 is slightly changed.
