Description

Assembly equipment for cam and clamp spring in automobile gearbox

Technical Field

The invention relates to the technical field of assembling and processing of automobile gearboxes, in particular to assembling equipment for a cam and a clamp spring in an automobile gearbox.

Background

As shown in fig. 1, the cam 2 is provided with a cam bore 2-2, which is provided with an edge angle 2-1 at its extended end. As shown in fig. 2, the circlip 1 has a circlip inner hole 1-1. As shown in fig. 3, a shaft plate 65 is fixedly arranged at the lower end of the sleeve shaft 52, and the diameter of the shaft plate 65 is larger than that of the sleeve shaft 52 so as to form a platform abutting against the snap spring 1. One end of the shaft plate 65 is bent upward to form a flap 55.

As shown in fig. 3, the assembled parts have the following structure: torsion spring 4 suit is on sleeve 52, arranges torsion spring 4's bottom in on axle plate 65, and torsion spring 4 undermost extension end and folded plate 55's side butt to when can realizing sleeve 52 rotatory, promote torsion spring 4 together rotatory through folded plate 55. The upper end of the torsion spring 4 is provided with a torsion spring supporting leg 3. And at the upper end position of the sleeve shaft 52 on the torsion spring 4, a piece of snap spring 1 is respectively arranged at the upper side and the lower side of the cam 2, namely, the inner holes of the snap springs are assembled with the sleeve shaft 52. The lower end face of the edge angle 2-1 of the cam 2 is convexly provided with a socket 2-3, and the socket 2-3 is inserted on the torsion spring supporting leg 3 of the torsion spring 4.

At present, the assembly of the cam 2 is generally completed manually, the efficiency is low, and the cam often has strict relative position requirements with other parts, which puts high requirements on the precision of the automatic assembly of the cam and also brings great difficulty.

The manual assembly that also adopts during the assembly of jump ring 1 often needs to press from both sides with the help of jump ring pincers to the jump ring and gets, compress (open), step such as assembly, requires the operator to pay attention to when pressing from both sides to aim at and press from both sides the position of getting very much to avoid pressing from both sides and get the failure. When the clamp spring is compressed (opened), extra force is needed, the clamp spring is easy to bounce and break away from the clamp spring to hurt people, so that the requirement on the skill of an operator is high, the physical consumption is large after the clamp spring is used for a long time, and fatigue is easy to generate. The clamp spring is easy to be excessively opened in the manual assembly (the manual operation problem exists, and errors such as the shape, the position and the size of a small hole and a large hole of the clamp spring exist, and the clamp spring is easily excessively opened in the manual assembly, so that the clamp spring is excessively large in size and separated from a clamp spring groove, the function is invalid, and serious safety risks are easily caused.

At present, there is also automatic operation to the assembly of jump ring, but it has following several problems:

firstly, in a common conical surface guide type snap spring press-fitting mode, the surface of a shaft is scraped during press-fitting, and the snap springs can be press-fitted from the same direction and only one snap spring can be assembled at a time;

the clamp spring is easy to clamp in the assembling process, because the clamp spring must keep the end surface horizontal in the assembling process, otherwise the clamp spring cannot completely enter the clamp spring groove, and once the clamp spring is inclined, the clamp spring is clamped on a shaft or a hole or bounces off in the transferring process of the clamp spring;

and thirdly, when the clamp spring for the shaft is assembled, the two small holes of the clamp spring are used for grabbing, so that the clamp spring inner hole 1-1 is opened, and the opening size of the clamp spring inner hole 1-1 is limited by errors such as the shape, the position, the size and the like between the small hole in the clamp spring and the clamp spring inner hole, so that the opening size of the clamp spring inner hole is inconsistent every time, the assembled clamp spring is easily opened excessively or too small, and the clamp spring is ineffective or blocked by a mechanism. Meanwhile, the consistency of the positions of the small holes is difficult to guarantee the assembly position by automatic grabbing realized by positioning and assembling the small holes, and the clamping of the two small holes is easy to cause unstable posture and also can cause clamping stagnation to cause assembly failure.

As shown in fig. 5, the torsion spring limiting mechanism 9 is an assembly station, where the circlip, the cam and the torsion spring are all installed, and finally the assembly shown in fig. 3 is formed.

As shown in fig. 6, the torsion spring limiting mechanism 9 includes a pressing block 14, a baffle 15, a speed reducing motor 16, and a gear pair 17.

The speed reducing motor 16 and the pressing block 14 are arranged side by side on the frame 51, and a gear pair 17 is arranged between the speed reducing motor and the pressing block and is rotatably installed with the horizontal working table 51-1. The pressing block 14 is provided with a clamping groove 53 capable of clamping the sleeve shaft 52, and the clamping groove 53 can be clamped on the side wall of the sleeve shaft 52 in a butt-clamping manner. When the pressing piece 14 is driven to rotate by the reduction motor 16, the sleeve shaft 52 fixed with the pressing piece 14 by clamping rotates together. At this time, the folded plate 55 drives the torsion spring 4 to rotate together until the torsion spring support leg 3 contacts the baffle 15, and then the rotation is stopped to enter a state to be assembled.

When the cam 2 is placed, the socket 2-3 is placed in alignment with the limiting shaft 12-2, and therefore other parts of the cam 2 are placed in a space defined by the flanges 12-3.

As shown in figure 5, a cam grabbing mechanism 10 is arranged above the cam discharging mechanism 12, the cam grabbing mechanism 10 is suspended above the cam discharging mechanism 12 through a stand column installed on a rack 51 and a plate chain arranged on the stand column, and is positioned between the cam discharging mechanism 12 and the torsion spring limiting mechanisms 9.

The correcting assembly comprises a supporting rod 59, a finger rod 20, a connecting plate 60 and two sixth air cylinders 50 mounted on the cantilever plate 56, wherein a supporting lug 57 is mounted on one side of an expansion rod of each sixth air cylinder 50, a supporting shaft 58 is arranged at the bottom of each supporting lug 57, one end of the supporting rod 59 is inserted into each supporting lug 57, and the upper end face of the inserted end of the supporting rod 59 is connected with the inner top face of each supporting lug 57 through a spring 21. Meanwhile, the telescopic rod of the sixth cylinder 50 is inserted into the spring 21, and is extended to abut against the supporting rod 59 when needed, and is retracted when not needed, so that the telescopic rod and the supporting rod are not in contact. The other end of the supporting rod 59 is hinged with the finger rod 20, and the tail end of the finger rod 20 is hinged with a roller. The connecting plate 60 connects the two hinged fingers 20, and a mounting plate 61 is hinged at the middle of the connecting plate 60, and the mounting plate 61 is connected with the cantilever plate 56.

The hinge point in the middle of the mounting plate 61 is a pivot, when the cam grabbing mechanism 10 contacts the cam 2, the edge angle 2-1 of the cam 2 firstly enters between the two finger rods 20 and extrudes the supporting rod 59, the supporting rod 59 pushes the cam 2 to the symmetrical axis positions of the two finger rods 20 under the action of elastic force, and the cam stops moving after the elastic force on the two sides is balanced.

When the sixth cylinder 50 is actuated, the telescopic rod thereof extends to abut against one end of the supporting rod 59 extending into the supporting lug 57 and moves downwards, and the other end of the supporting rod 59 moves upwards, so that the finger rods 20 are driven to rotate inwards (in the direction that the two finger rods approach each other); otherwise, the rotation is outward; the position of the cam 2 is adjusted slightly by repeating the above steps, so that the cam is sleeved on the torsion spring supporting leg 3.

When the socket 2-3 on the cam 2 and the torsional spring supporting leg 3 are assembled unsuccessfully due to slight disalignment, the finger rods 20 can be driven to continuously open and close by the staggered up-and-down action of the sixth air cylinders 50 on the two sides, and the cam 2 is subjected to intermittent extrusion. Meanwhile, the sixth cylinder 50 is not directly connected with the finger rod 20, but exerts acting force through the spring 21, so that a buffering effect is achieved, slight vibration is formed, the cam 2 and the torsion spring support leg 3 are favorably assembled into work in the buffered slight vibration, and an abnormal condition correcting effect is achieved to a certain degree.

As shown in fig. 9, the gripping assembly includes a three-finger gripper 19, which is mounted on the pneumatic gripper of the cylinder and is driven by the pneumatic gripper, as is known in the art. The three-finger clamping jaw 19 is simultaneously opened under the action of the cylinder to expand the inner hole 2-2 of the cam, so that the self-centering grabbing effect is achieved.

The pressing component comprises a cylinder (not numbered) and a pressing rod 18 which is in driving connection with the cylinder. The air cylinder is arranged on the cantilever plate 56, and the pressure lever 18 is positioned in the middle of the three-finger clamping jaw 19 and stretches downwards.

When grabbing, the finger rod 20 is in contact with the edge angle 2-1 of the cam 2 and is often initially positioned, the pressure rod 18 abuts against the end face of the cam 2, and then the three-finger clamping jaw 19 is internally supported and abutted against the inner hole 2-2 of the cam, so that stable grabbing is achieved.

The specific working principle is as follows: the cam grabbing mechanism 10 descends, the edge angle 2-1 of the cam 2 enters between the two fingers 20, and the fingers 20 can act synchronously to correct the position of the cam 2, so that the cam 2 moves to the position of the symmetry axis of the two fingers 20. The plunger 18 is actuated so that it contacts the cam 2 and compresses. The three-finger clamping jaw 19 is opened, the cam 2 is expanded from the inner hole 2-2 of the cam, the grabbing effect is achieved, and the cam grabbing mechanism 10 drives the cam 2 to ascend. After the first clamp spring 1 is installed, the cam 2 is assembled.

The side of the positioning support 24, which is far away from the push plate 25, is provided with a vertically through blanking port (not shown), and the blanking port is located at the vertically extending end of the cartridge clip type bin 27. And a top rod 28 is telescopically arranged at the top of the blanking port, and the top rod 28 is driven by the first air cylinder 22. The sliding groove 49 is horizontally communicated with the blanking port. The push plate 25 is driven by a second cylinder 26 mounted on a base 62. The first cylinder 22 is disposed on the guide 23.

As shown in fig. 4 and 11, the cartridge magazine 27 is connected to a vibration plate, and is automatically loaded by the vibration plate. The clip type storage bin 27 is stacked, the clamp spring 1 placed at the lowest position is placed in the sliding groove 49, the height of the sliding groove 49 is only used for the space of one clamp spring 1, and when the clamp spring 1 is pushed out by the push plate 25, the clamp spring automatically falls down by self weight.

The push plate 25 is formed with a first position, a second position and a third position in a telescopic manner, and in the first position, the push plate 25 is far away from the positioning support 24. In the second position, the pusher 25 projects into the positioning seat 24 and the slide groove 49, arranged adjacent to the cartridge magazine 27 (i.e. in contact with the latch spring 1 that falls into the slide groove 49). When the third position, the push plate 25 continues to extend into the position close to the blanking port (i.e. the clamp spring 1 is pushed into the blanking port). And then the first cylinder 22 pushes the ejector rod 28 to act, so that the clamp spring 1 is pushed out from the blanking port and falls. The cross-section of push pedal 25 is T shape, is the installation of falling T shape during the installation, has the horizontal limit that can sliding fit promptly to and can promote the vertical limit of jump ring displacement, the precision is better, and slip displacement stability is better.
