Description

Technical Field

[0001] The invention relates to the technical field of bearing processing, in particular to an automatic loading and unloading mechanism for a synchronous ring inner and outer diameter superfinishing machine. Background Art

[0002] The traditional method of super-finishing in the bearing industry is to use a product fixture to center the workpiece to be processed, and the workpiece to be processed rotates under the drive of the drive plate, and then the bearing is subjected to rough grinding, fine grinding and super-finishing processing processes in sequence. During the rough grinding, fine grinding and super-finishing process, the rough oil stone, fine oil stone and super-fine oil stone enter the groove to perform rough and super-finishing processing on the raceway. During the oil stone processing of the bearing ring, the oil stone needs to reciprocate and oscillate in the direction perpendicular to the rotation of the workpiece surface, and super-finish with the rotation speed of the workpiece and the pressure on the workpiece surface.

[0003] In the existing lapping machine processing process, the loading and unloading methods are usually done manually, or pushed by hydraulic cylinders or pneumatic cylinders. The loading and unloading methods are relatively cumbersome and have poor stability, which affects the processing efficiency. Moreover, most of the existing lapping machines can only clamp and position one type of bearing. When lapping different types of bearings is required, the fixture needs to be replaced.

[0029] See also Figure 3 , Figures 6 to 8 , Fig.10 The clamping assembly includes a transmission column 6 movably inserted in the slide groove 22, and a convex block 61 is fixedly connected to the upper end of the transmission column 6. The upper end of the convex block 61 passes through the convex guide groove 25 and the through groove 31 in sequence and is fixedly connected to the cylinder 62. The upper end of the side of the cylinder 62 is fixedly sleeved with a limiting ring 63, and the upper end of the cylinder 62 is fixedly connected with a plurality of slide rods 64 in an annular array.

[0031] The annular table 21 rotates to drive the slide groove 22 to slide along the transmission column 6. At the same time, the annular table 21 rotates to push the transmission column 6 to move. The transmission column 6 drives the convex block 61 to slide along the convex guide groove 25. The convex block 61 drives the roller 66 to move through the cylinder 62, so as to adjust the distance between the three rollers 66. The three rollers 66 cooperate to clamp and position the workpiece 15. At the same time, the cylinder 62 drives the upper pressure plate 7 to move through the slide rod 64, so that the upper pressure plate 7 is clamped at the upper end of the workpiece 15. Since the oilstone needs to oscillate back and forth in a direction perpendicular to the rotation direction of the workpiece 15 surface, the workpiece 15 may be shaken, thereby causing the workpiece 15 to loosen or fall off. The upper end of the workpiece 15 is limited and fixed by the upper pressure plate 7 provided. At this time, the three rollers 66 and the three upper pressure plates 7 cooperate with each other to clamp and position the workpiece 15, so that the workpiece 15 can be stably ground.

[0032] See also Figure 6 and Fig. 9The upper end of the support plate 3 is symmetrically provided with fan-shaped grooves 32 on both sides of the lowest through groove 31. The support assembly includes an arc rod 5 symmetrically fixedly connected to the two fan-shaped grooves 32.

[0033] The fan-shaped block 52 is slidably connected to the fan-shaped groove 32, an arc-shaped hole is penetrated through the side of the fan-shaped block 52, the arc-shaped rod 5 is inserted into the arc-shaped hole, the fan-shaped block 52 is slidably connected to the arc-shaped rod 5, the two ends of the return spring 51 are respectively abutted against the fan-shaped groove 32 and the fan-shaped block 52, the upper end of the fan-shaped groove 32 is provided with a fan-shaped mounting groove, the fan-shaped baffle 54 is slidably connected to the fan-shaped mounting groove, and the upper end surface of the fan-shaped baffle 54 and the upper end surface of the support plate 3 are on the same inclined surface.

[0034] When the lowest roller 66 moves upward, after the roller 66 contacts the support wheel 53, the roller 66 pushes the two support wheels 53 to move away from each other, and the support wheel 53 drives the fan-shaped block 52 to slide along the fan-shaped groove 32 through the shaft. At this time, the fan-shaped block 52 slides along the arc rod 5, and the fan-shaped block 52 squeezes the reset spring 51.

[0035] Under the action of the elastic force of the return spring 51, the two sector blocks 52 are brought closer to each other. At this time, the two sector blocks 52 are at one end of the two sector grooves 32 that are closer to each other. The sector blocks 52 drive the two support wheels 53 to move closer to each other. At this time, one side of the workpiece 15 contacts the support plate 3, and the oblique lower side of the workpiece 15 contacts the two support wheels 53. The workpiece 15 can be supported by the two support wheels 53. The loading and unloading mechanism pushes the workpiece 15 waiting to be processed along the loading guide seat 35 to the top of the two support wheels 53. At the same time, the workpiece 15 waiting to be processed pushes the processed workpiece 15 away from the top of the two support wheels 53, so that the processed workpiece 15 slides down along the support wheels 53 and the support plate 3 to the unloading table 34, thereby completing the automatic loading and unloading of the workpiece 15.

[0036] See also Figure 7 , Figure 8 and Fig.10The lifting and lowering adjustment mechanism includes a lifting screw 8 which is rotatably installed on the upper end of the cylinder 62 through a pin shaft. The lower end of the lifting screw 8 is fixedly connected to the pin shaft, and the pin shaft is rotatably connected to the cylinder 62.

The upper and lower ends of the locking spring 83 are respectively abutted against the positioning plate 82 and the rotating crown gear 84. The rotating crown gear 84 is clamped with the positioning crown gear 65, and the outer side of the rotating crown gear 84 is fixedly sleeved with an adjusting sleeve 85.

[0037] The locking spring 83 applies a downward elastic force to the rotating crown gear 84, so that the rotating crown gear 84 always maintains a tendency to engage with the positioning crown gear 65; When it is necessary to clamp and position the workpieces 15 at different heights, first pull the adjusting sleeve 85 upwards, and the adjusting sleeve 85 drives the rotating crown gear 84 to slide upwards along the cross rod 81, and the rotating crown gear 84 squeezes the locking spring 83, and at the same time, the rotating crown gear 84 is separated from the positioning crown gear 65; at this time, rotating the adjusting sleeve 85 drives the rotating crown gear 84 to rotate, and the rotating crown gear 84 drives the lifting screw 8 to rotate synchronously through the cross rod 81, and when the lifting screw 8 rotates, it drives the upper pressure plate 7 to slide up and down along the slide rod 64, thereby adjusting the height of the upper pressure plate 7, so that the upper pressure plate 7 can clamp and position the workpieces 15 at different heights.

[0038] Working principle: During operation, the workpiece 15 is conveyed to the loading platform 33, and the workpiece 15 slides down along the loading platform 33 onto the support plate 3, and the workpiece 15 contacts the side surface of the loading guide seat 35, and at the same time, the side surface of the workpiece 15 contacts the pushing part of the pushing head 45; At this time, the grinding assembly 12 completes the grinding process of the previous workpiece 15, and the piston rod of the hydraulic cylinder 27 contracts to drive the tooth plate 26 to move along the L-shaped limit seat 13, the tooth plate 26 drives the gear ring 23 to rotate, the gear ring 23 drives the annular table 21 to rotate, the annular table 21 drives the slide groove 22 to slide along the transmission column 6, and at the same time, the annular table 21 rotates to push the transmission column 6 to move, the transmission column 6 drives the convex block 61 to slide outward along the convex guide groove 25, and the convex block 61 drives the roller 66 to move outward through the cylinder 62, so that the three rollers 66 move away from each other; The three clamping assemblies are driven away from each other by the clamping drive mechanism, so that the clamping assemblies release the clamping and positioning of the workpiece 15, and at the same time, the clamping assembly at the bottom is separated from the supporting assembly, so that the supporting assembly is reset.

[0039] The inner rod of the push cylinder 41 extends to push the slide 43 to move obliquely upward along the guide rail 42, and the slide 43 drives the push plate 44 to slide left and right along the support plate 3 and the loading guide seat 35. At the same time, the push plate 44 drives the push head 45 to move, and the push head 45 pushes the workpiece 15 to be processed to move obliquely upward along the side of the loading guide seat 35; When the workpiece 15 to be processed contacts the processed workpiece 15, the workpiece 15 to be processed pushes the processed workpiece 15 to move, so that the processed workpiece 15 slides down along the support wheel 53 and the support plate 3 to the unloading table 34, thereby completing the automatic unloading of the workpiece 15. At the same time, the workpiece 15 to be processed moves along the support plate 3 and the loading guide seat 35 to the upper side of the support assembly, and the workpiece 15 to be processed is supported by the two support wheels 53 in the support assembly, thereby completing the loading of the workpiece 15, and then the inner rod of the pushing cylinder 41 is contracted to reset the loading and unloading mechanism.

[0040] Then, the piston rod of the hydraulic cylinder 27 extends to drive the tooth plate 26 to move along the L-shaped limit seat 13, the tooth plate 26 drives the gear ring 23 to rotate in the opposite direction, the gear ring 23 drives the annular table 21 to rotate in the opposite direction, the annular table 21 drives the slide groove 22 to slide along the transmission column 6, and at the same time, the annular table 21 rotates to push the transmission column 6 to move, the transmission column 6 drives the convex block 61 to slide inward along the convex guide groove 25, and the convex block 61 drives the roller 66 to move inward through the cylinder 62, so that the three rollers 66 move closer to each other; When the lowest roller 66 moves upward, after the roller 66 contacts the support wheel 53, the roller 66 pushes the two support wheels 53 to move away from each other, and at the same time, the upper pressure plate 7 is stuck at the upper end of the workpiece 15. At this time, the lowest roller 66 pushes the workpiece 15 to move upward, and at the same time, the other two rollers 66 approach the workpiece 15. The three rollers 66 and the three upper pressure plates 7 cooperate to clamp and position the workpiece 15.

[0041] By adjusting the extended length of the hydraulic cylinder 27, the distances by which the three clamping assemblies move toward each other are adjusted, so that the three clamping assemblies can clamp and position workpieces 15 of different diameters.

[0042] The three clamping components can clamp and position the side and upper end of the workpiece 15 to prevent the workpiece 15 from shaking, deflecting, erroring, falling off, etc. during the grinding process, so that the workpiece 15 can be ground stably to ensure the quality of the ultra-precision grinding process.

[0043] When it is necessary to clamp and position the workpieces 15 at different heights, first pull the adjusting sleeve 85 upwards, the adjusting sleeve 85 drives the rotating crown gear 84 to slide upwards along the cross rod 81, the rotating crown gear 84 squeezes the locking spring 83, and at the same time the rotating crown gear 84 is separated from the positioning crown gear 65. At this time, the rotating adjusting sleeve 85 drives the rotating crown gear 84 to rotate, and the rotating crown gear 84 drives the lifting screw 8 to rotate synchronously through the cross rod 81. When the lifting screw 8 rotates, it drives the upper pressure plate 7 to slide up and down along the slide rod 64, so as to adjust the height of the upper pressure plate 7, so that the upper pressure plate 7 can clamp and position the workpieces 15 at different heights. After the adjustment is completed, the adjusting sleeve 85 is loosened, and the rotating crown gear 84 slides downward along the cross rod 81 under the action of the elastic force of the locking spring 83, so that the rotating crown gear 84 is engaged with the positioning crown gear 65, so that the rotating crown gear 84 cannot rotate. At this time, the cross rod 81 and the lifting screw 8 cannot rotate either, and the upper pressure plate 7 cannot move up and down, so that the upper pressure plate 7 can stably clamp and position the upper end of the workpiece 15.

[0044] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
