As shown in fig. 1 to 7, a polishing apparatus for machining according to an embodiment of the present invention includes a frame 100, and a conveyor 200 that can be circulated, a centering device 300 that performs centering treatment on a workpiece, and a polishing apparatus 400 for machining that performs polishing treatment on a workpiece are provided on the frame 100. The centering device 300 includes a gravity detection mechanism, a position detection mechanism, and a guide mechanism. The gravity detection mechanism comprises a third conveyor belt 303, when a workpiece moves onto the third conveyor belt 303, the gravity detection mechanism can detect the quality of the workpiece, specifically the horizontal height of the third conveyor belt 303 is inversely proportional to the quality of the workpiece on the third conveyor belt 303, the position detection mechanism can detect the position of the workpiece on the conveyor belt, specifically the distance of the workpiece deviating from the center line of the third conveyor belt 303, and the guiding mechanism can guide the deviated workpiece to move to the preset position of the conveyor belt again.
Specifically, when the workpiece moves on the third conveyor belt 303 with a positional deviation, the gravity detecting mechanism can lift the third conveyor belt 303 according to the mass of the workpiece, and the larger the mass of the workpiece is, the more the third conveyor belt 303 is lowered, and the larger the force required to open the guide mechanism is. The position detecting mechanism adjusts the force required for opening the guide mechanism again according to the deviated position of the workpiece, and the force required for opening the guide mechanism biased to the workpiece side is larger than the force required for opening the guide mechanism far from the workpiece side. The forces required to open the guide mechanism are different from each other so that the workpiece cannot pass through the guide mechanism, and the workpiece moves along the guide mechanism to a predetermined position on the conveyor belt, where it passes through the guide mechanism and into the polishing apparatus 400 for machining. The workpiece is perfectly matched with the polishing device 400 for machining, and the polishing efficiency is higher.
As shown in fig. 3 and 4, in some embodiments, the gravity detection mechanism further includes a first conveyor belt 301, a second conveyor belt 302, and a fourth conveyor belt 304. The first conveyor belt 301 is connected to the frame 100 by a first elastic member, and the first conveyor belt 301 is slidable on the frame 100. The first elastic member resets or has a tendency to reset the first conveyor belt 301 during sliding. The first conveyor belt 301 is movably connected with the second conveyor belt 302 by the first connecting belt 306, so that the second conveyor belt 302 can generate corresponding activity change along with the sliding of the first conveyor belt 301. Meanwhile, the second conveyor belt 302 is movably connected with the third conveyor belt 303 through a second connecting belt 307, the third conveyor belt 303 is movably connected with the fourth conveyor belt 304 through a third connecting belt 308, and the fourth conveyor belt 304 is rotatably connected with the frame 100. That is, the first belt 301, the second belt 302, the third belt 303, and the fourth belt 304 can be changed in position in unison with the pivot point at the rotational connection point of the fourth belt 304 and the frame 100.
In particular, in this embodiment, the frame 100 is provided with a transverse slot 101 at the first conveyor belt 301, and two sides of the first conveyor belt 301 are provided with elongated protrusions 305, and the protrusions 305 extend into the transverse slot 101, so that the first conveyor belt 301 can slide along the transverse slot 101. The first elastic member disposed in the transverse groove 101 is a tension spring, and the tension spring is disposed at one end close to the second conveyor belt 302 and connected to the second connecting belt 307, and the tension spring is stretched during the sliding process of the first conveyor belt 301, so that a tension force is generated to reset the first conveyor belt 301 or a reset trend is provided. Meanwhile, the first elastic member may be a compression spring, which is disposed at one end of the transverse slot 101 away from the second conveyor belt 302 and connected to the bump 305 on the first conveyor belt 301, where the compression spring is compressed during the sliding process of the first conveyor belt 301, and generates a thrust force to reset the first conveyor belt 301 or has a reset tendency.
Further, the initial level of the third conveyor 303 is higher than the first, second and fourth conveyors 301, 302, 304. In the polishing process of the workpiece, the workpiece is placed on the corresponding balancing weights for maintaining stability, and the balancing weights are different in quality according to the difference of the quality of the workpiece. When the weight moves onto the third conveyor belt 303, the third conveyor belt 303 is lowered by the pressure of the weight and the workpiece, and simultaneously the first conveyor belt 301 slides, the second conveyor belt 302 and the fourth conveyor belt 304 are rotated. The height at which the third conveyor 303 descends is different depending on the mass of the work pieces on the weights, and the greater the mass of the work pieces, the more the height at which the third conveyor 303 descends, i.e., the smaller the horizontal height of the third conveyor 303. At this time, the quality of the workpiece is reflected to the level of the third conveyor 303.
As shown in fig. 3, 4, 5, and 7, the position detecting mechanism includes a cover plate 310 and a jack 320. A cover plate 310 covers over the centering device 300 and is coupled to the frame 100. The frame 100 is provided with a groove 102, and one end of a cover plate 310 extends into the groove 102, so that the cover plate 310 can slide up and down along the groove 102. A second elastic member is disposed in the groove 102, and the groove 102 and the cover plate 310 are connected together by the second elastic member. In the initial state, the cover 310 is attached to the groove 102, and when the cover 310 slides upwards under the action of external force, the second elastic member is stretched, and a pulling force is generated to enable the cover 310 to return to the initial position or have a tendency to return to the initial position. The bottom of the cover plate 310 is also provided with a chute, and correspondingly, the top of the ejector rod 320 is provided with a first sliding block 321. The first sliding block 321 is connected to the sliding groove, so that the ejector rod 320 can slide in the sliding groove.
Specifically, two side plates 330 are further disposed on two sides of the third conveyor 303, the two side plates 330 are connected through a transverse plate 331, a plurality of through holes 332 are formed in the transverse plate 331, and the ejector rod 320 passes through the through holes 332 and is connected with the sliding groove on the cover plate 310. When the position of the third conveyor belt 303 changes, the position of the side plate 330 changes along with the third conveyor belt 303, and the through hole 332 on the transverse plate 331 slides up and down on the ejector rod 320, so as to ensure that the position change of the third conveyor belt 303 is not affected, and meanwhile, the transverse plate 331 drives the ejector rod 320 to slide in the chute. I.e. the position of the carrier bar 320 is changed only in height with respect to the third conveyor 303 and not in horizontal position.
Further, the ejector 320 further includes a first sleeve 322, a second sleeve 323, and an ejector block 324, where the first sleeve 322 is connected to the first slider 321, and the second sleeve 323 is connected to the ejector block 324. The first sleeve 322 is sleeved with the second sleeve 323, and the inner parts of the first sleeve and the second sleeve are connected through a third elastic piece. When the ejector block 324 is pressed, the ejector rod 320 has a rising trend, and the first sleeve 322 and the second sleeve 323 are pressed close to each other at the same time, so that the third elastic member is compressed to generate a pushing force to push the first sleeve 322 and the second sleeve 323, and the first sleeve 322 and the second sleeve 323 are separated or have a separating trend.
Further, a pushing surface is provided at the bottom of the top block 324. When the workpiece on the third conveyor 303 moves to the ejector rod 320, the workpiece pushes the pushing surface, so that the ejector block 324 is lifted, i.e. the ejector rod 320 is lifted.
Specifically, the pushing surface is a surface with a certain inclination, which may be an inclined surface, an arc surface or a spherical surface, or may be a combined surface of two arc surfaces of one inclined surface and two arc surfaces of two sides, so long as the workpiece can be smoothly pushed up by the pushing block 324. When the position of the workpiece on the third conveyor 303 deviates, the number of the lifters 320 lifted under the side plate 330 closer to the workpiece is greater, that is, the side plate 330 is pushed by the third elastic member more, and the lifting height of the cover plate 310 on the side is higher under the interaction of the pushing force of the third elastic member and the pulling force of the second elastic member. At this time, the rising heights of the two side cover plates 310 are not uniform, and the position of the workpiece is also represented by the rising height difference of the two side cover plates 310.
As shown in fig. 6 and 7, the guide mechanism includes a screw 360, a guide plate 340, and a combination connector 350. The screw rod 360 is fixed on the side plate 330, and the screw rod 360, the side plate 330 and the third conveyor 303 form a moving body, and the positions of the three are changed together. A spiral groove 361 is formed in the spiral rod 360. The guide plate 340 is rotatably connected to the screw rod 360, and the length of the guide plate 340 is greater than half of the width of the third conveyor belt 303 and less than the width of the third conveyor belt 303. Such a length setting will cause the guide plate 340 to have an angle when closed, along which the workpiece moves to the position where the guide plate 340 is closed, i.e. at the centre line of the third conveyor 303. The combined connecting piece 350 is sleeved on the spiral rod 360, a matching block matched with the spiral groove 361 is arranged on the combined connecting piece 350, and when the position of the spiral rod 360 changes along with the third conveying belt 303, the matching block spirally slides in the spiral groove 361 to drive the combined connecting piece 350 to rotate.
Further, the composite link 350 includes a second slider 351, a third sleeve 352, a fourth sleeve 353, and a collar 354. The second slider 351 is at the same height as the first slider 321, and is connected in the chute, and can slide in the chute, so that the combined connecting piece 350 can move transversely together with the screw rod 360 when the position of the screw rod 360 changes. The third sleeve 352 is rotatably connected to the second slider 351, so that the third sleeve 352 can also rotate during the process of lifting and lowering along with the second slider 351. The third sleeve 352 is sleeved with the fourth sleeve 353, and the inside is connected through a fourth elastic member. When the third sleeve 352 rises along with the second slider 351, the fourth elastic member is stretched, and a pulling force is generated to drive the fourth sleeve 353 to move together with the third sleeve 352 or have a tendency to move together. The fourth sleeve 353 is provided with a sleeve 355, the collar 354 is provided with a sleeve rod 356, and the sleeve 355 and the sleeve rod 356 are sleeved together, so that the fourth sleeve 353 and the collar 354 can synchronously rotate, and the sleeve 355 and the sleeve rod 356 can stretch and retract.
Specifically, the mating block is disposed on the fourth sleeve 353, and the mating block slides in the spiral groove 361 to drive the fourth sleeve 353 to rotate, and the fourth sleeve 353 rotates to drive the combined connector 350 to integrally rotate.
Further, a fifth elastic member connection is provided between the collar 354 and the guide plate 340, the fifth elastic member being used to control the closing degree of the guide plate 340. In this embodiment, the clockwise rotation of the collar 354 will cause the fifth spring to accumulate force, closing the guide plate 340 more tightly, and opening the guide plate 340 requires more force.
Further, the screw 360 and the combination connector 350 control the degree of difficulty in opening the guide plate 340 according to the detection results of the gravity detection mechanism and the position detection mechanism. Namely, the screw 360 and the combination link 350 control the degree of accumulation of the fifth elastic member according to the detection results of the gravity detection mechanism and the position detection mechanism.
Specifically, when the third conveyor 303 is lowered by the gravity of the workpiece and the balancing weight, the screw 360 is driven to descend together, and at this time, the combined connecting piece 350 is connected to the cover plate 310 by the second slider 351, and the cover plate 310 does not descend under the obstruction of the frame 100, i.e. the combined connecting piece 350 does not descend. The combined connecting member 350 rises relative to the screw rod 360, and the mating block on the fourth sleeve 353 slides in the spiral groove 361 to drive the fourth sleeve 353 to rotate clockwise, and the fourth sleeve 353 drives the collar 354 to rotate clockwise, i.e. the fifth elastic member stores force. The workpiece moves to the lower part of the ejector rod 320, the ejector rod 320 is jacked up, the ejector rod 320 jacks up the cover plate 310, the cover plate 310 drives the combined connecting piece 350 to ascend through the second sliding block 351, at the moment, the spiral rod 360 is in a descending state or the position is stable, the combined connecting piece 350 ascends relative to the spiral rod 360, the matching block on the fourth sleeve 353 slides spirally in the spiral groove 361 to drive the fourth sleeve 353 to rotate clockwise, and the fourth sleeve 353 drives the sleeve ring 354 to rotate clockwise, namely the fifth elastic piece further stores force.
In combination with the above embodiment, the use principle and working process of the embodiment of the present invention are as follows:
the workpiece is placed on a balancing weight which moves on a conveyor belt. When the weight is moved onto the third conveyor 303, the third conveyor 303 is lowered under the influence of the weight and the weight of the work thereon, while the first conveyor 301 slides, the first elastic member is stretched, and the second conveyor 302 and the fourth conveyor 304 are rotated accordingly. The carrier bar 320 moves laterally with the third conveyor belt 303 along the chute at the bottom of the cover plate 310 by the transverse plate 331. The assembly connection 350 is sleeved on the screw rod 360 and also moves transversely along the chute at the bottom of the cover plate 310 together with the third conveyor belt 303.
The cover plate 310 covers the frame 100 without being affected by the lifting of the third conveyor 303. The screw rod 360 descends along with the third conveyor belt 303, the guide plate 340 descends along with the screw rod 360, the combined connector 350 does not descend due to the connection of the top second slider 351 in the cover plate 310, but the collar 354 at the bottom of the combined connector 350 is connected with the guide plate 340 through the fifth elastic member, and the collar 354 descends along with the guide plate 340, which is represented by the sleeve 355 and the sleeve 356 being partially elongated. The combined connecting piece 350 ascends relative to the screw rod 360, the matching block on the fourth sleeve 353 slides in the screw groove 361 in a screw mode, the fourth sleeve 353 rotates clockwise, the fourth sleeve 353 drives the lantern ring 354 to rotate clockwise, accordingly, the fifth elastic piece stores force, the guide plate 340 is closed more tightly, and the force required for opening the guide plate 340 is larger.
The height at which the third conveyor 303 descends is different depending on the weight and the quality of the work, resulting in a difference in the degree of accumulation of the fifth elastic member, and a difference in the force required to open the guide plate 340. The balancing weights and the workpieces with different models can be embodied.
The balancing weight continues to move on the third conveyor 303 and contacts the jacking block 324, the jacking block 324 is jacked up through the jacking surface at the bottom of the jacking block 324, the jacking block 324 is extruded to move upwards, the third elastic piece connected between the first sleeve 322 and the second sleeve 323 is compressed to generate thrust, and the jacking force of the balancing weight to the jacking block 324 and the thrust generated by the third elastic piece enable the jacking rod 320 to jack the cover plate 310. During the lifting of the cover 310, the second elastic member is stretched to generate a tensile force. The pulling force, the pressing force and the pushing force interact to raise the cover plate 310 by a certain height. The lifting of the cover plate 310 drives the combined connecting piece 350 to lift, which means that the cover plate 310 drives the second slider 351 to lift, the second slider 351 drives the third sleeve 352 to lift, and the third sleeve 352 drives the fourth sleeve 353 to lift through the fourth elastic piece. At this time, the screw rod 360 is still in the process of being lowered or has stabilized at a certain position, the combined connecting member 350 is raised again relative to the screw rod 360, and the fifth elastic member again stores force.
When the positions of the balancing weights on the third conveyor 303 deviate, the number of the push rods 320 jacked up on two sides of the center line of the third conveyor 303 is different, that is, the thrust generated by the third elastic members on two sides is different, so that the lifting heights of the cover plates 310 on two sides are different, that is, the storage degrees of the fifth elastic members on two sides are different, the force required for opening the guide plates 340 on two sides is different, and the guide plates 340 on one side, which are biased by the balancing weights, need to be opened with larger force.
The balancing weight moves to the guide plate 340, and since the force required to open the guide plate 340 is excessive, the balancing weight cannot pass through, so the balancing weight gradually moves to the center line area of the third conveyor belt 303 along the slope of the guide plate 340, i.e., the guide plate 340 is closed. In this process, the number of the side lifters 320 to be lifted gradually approaches, that is, the force required to open the side guide plates 340 gradually becomes the same. Since the moment arm at which the guide plate 340 is closed is the longest, the force required to open the guide plate 340 is also the smallest there, and the weight, after moving to the guide plate 340 closed, will open the guide plate 340 and be fed out in the region of the centre line of the third conveyor 303. The final balancing weight is fed into the polishing equipment 400 for machining in the center line area of the conveyor belt, so that the workpiece is matched with the polishing equipment 400 for machining more perfectly, and the polishing efficiency of the workpiece is improved.
Then the first elastic piece resets to drive the first conveyor belt 301, the second conveyor belt 302, the third conveyor belt 303 and the fourth conveyor belt 304 to reset; the second elastic piece, the third elastic piece and the fourth elastic piece are reset to drive the cover plate 310, the ejector rod 320 and the combined connecting piece 350 to reset; the fifth elastic member resets to drive the guide plate 340 to be closed. The centering process is performed again as the next weight moves onto the third conveyor 303.
