Description

Technical Field

[0001] This invention belongs to the field of bearing processing technology, and more specifically relates to an automated grinding and chamfering device for bearing filler balls. Background Technology

[0002] In the structure of a cross bearing, the filler ball block is a key component that fills the inner ring filler ball hole and ensures smooth assembly of the rollers. The chamfering treatment of its raceway edge can eliminate the sharp edges of the component, avoid scratching the rollers and damaging the raceway working surface during assembly and operation, and also alleviate stress concentration at the edge, thereby improving the reliability of the component.

[0003] Currently, automated edge grinding and chamfering devices often use a clamping head with a contour positioning cavity to support the workpiece, and two symmetrically distributed grinding wheels to simultaneously complete the chamfering of the two sides of the filler ball block. The reason for using contour positioning instead of conventional clamping is that the filler ball block is relatively small and has an irregular arc surface structure. Conventional clamping not only makes it difficult to ensure the consistency of the positioning reference, but also easily causes clamping deformation of thin-walled parts. The contour cavity can fit the outer contour of the workpiece to achieve limit, making the clamping and alignment more intuitive, and can also better avoid the workpiece deformation problem caused by clamping force. However, this processing method also has some limitations in actual use. For the locating fixture head, its positioning cavity needs to be compatible with the corresponding model of filler ball block. When switching to different specifications of filler ball blocks, it is often necessary to customize the corresponding specification of fixture head, and the operator needs to manually complete the replacement and alignment calibration. This not only increases the manufacturing and management cost of tooling, but also lengthens the processing cycle. Furthermore, the two grinding wheels are arranged close to each other, and the fixture head is located in the narrow space between them, which makes the chip removal space in the processing area very cramped. The metal chips generated by grinding and the abrasive grains that fall off the grinding wheel are difficult to be discharged smoothly and in a timely manner, and are prone to accumulate in the processing area. These hard particles may scratch the chamfered surface of the workpiece, affect the surface processing quality, and reduce the stability of the chamfer dimensions in the long-term processing. Summary of the Invention

[0004] This invention addresses the problem of overly simplistic solutions in existing technologies by providing a significantly different approach. Belonging to the technical field of bearing filler ball chamfering equipment, this invention primarily provides an automated grinding and chamfering device for bearing filler balls. This addresses the technical problem mentioned in the background section: in current automated grinding and chamfering devices, the profile fixture head cavity and the filler ball are only one-to-one matched, requiring tooling changes for different filler ball specifications, thus lacking universal applicability.

[0005] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: An automated grinding and chamfering device for bearing filler blocks includes a worktable with a grinding mechanism and a lifting mechanism. The output end of the lifting mechanism is equipped with a contour clamping mechanism for positioning the filler block body.

The rectangular channel passes through the corresponding rectangular opening. The blades are evenly distributed in the cover plate and face the chamfer side of the filling block body. The cover plate is installed on the upper end of the rectangular channel by bolts.

[0006] Preferably, a reset torsion spring is fitted on each of the two rotating shafts, and the lower end of the reset torsion spring is connected to the interface on the deflection limiting block, while the upper end of the reset torsion spring is connected to the interface on the upper side of the inner wall of the cover.

[0007] Preferably, a first driving assembly is provided on the base plate. The first driving assembly includes a moving plate, a first motor, and a first lead screw. A receiving block is connected to the moving plate by bolts. A support shaft is threaded into each of the two screw holes on the moving plate. A guide roller is provided on each support shaft. The guide roller contacts the guide surface of the corresponding deflection limiting block. A limiting cover is threaded to the upper end of each support shaft, and the limiting cover contacts and cooperates with the upper end of the guide roller.

[0008] Preferably, the output end of the first motor is provided with a square plug, one end of the first lead screw is provided with a square slot, the square slot cooperates with the square plug, and the first lead screw is provided with a first nut seat, which is connected to the receiving block by bolts.

[0009] Preferably, both ends of the non-threaded section of the first lead screw are provided with a first bracket, and the first bracket is connected to the base plate by bolts.

[0010] Preferably, the base plate is further provided with a second driving assembly, which includes a sliding seat and a second motor. The sliding seat is slidably connected to a slide rail, which is bolted to the base plate. The second motor is bolted to one side of the outer wall of the cover. The output end of the second motor is provided with a second lead screw, and a second nut seat is provided on the second lead screw. The second nut seat and the sliding seat are bolted together. The sliding seat is provided with a bending plate, which is bolted to the back of the push-pull limiting block. The non-threaded section of the second lead screw is provided with a second bracket, which is bolted to the upper side of the inner wall of the cover.

[0011] Preferably, the housing and the cover are connected by bolts, the upper side of the cover is provided with a pad, the pad is connected to the lower side of the bottom plate, a filter plate is snapped into the housing, and the filter plate divides the internal space of the housing into a collection chamber and an installation chamber, and a suction fan is provided in the installation chamber.

[0012] Preferably, the lifting mechanism includes a first frame, within which a third lead screw and a slide rod are disposed, the third lead screw and the slide rod being distributed in parallel, a third nut seat being disposed on the third lead screw, a slider being disposed on the slide rod, the slider and the third lead screw being connected together to a lifting seat, and the housing being located on the lifting seat, a third motor being disposed on the upper side of the first frame, the output end of the third motor being connected to the upper end of the third lead screw.

[0013] Preferably, the first frame is bolted to a support, and a nylon support block is provided on the support.

[0014] Preferably, the grinding mechanism includes a second frame, on which two mounting seats are provided. Each of the two mounting seats is provided with a fourth motor, and the output end of each of the fourth motors is provided with a grinding disc, which faces the chamfer side of the ball filling block body.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) The present invention uses a contouring fixture mechanism to drive the guide roller to push the two sides of the deflection limit block to open and close synchronously around the rotating shaft by means of the lead screw drive. With the help of the push-pull limit block that can be moved back and forth, the three limit surfaces together enclose the contouring positioning port. The size of the contouring positioning port can be adjusted synchronously with the position of the deflection limit block and the push-pull limit block. It can cover the processing needs of various specifications of filler blocks in the same series. In terms of workpiece positioning, the contouring positioning port design with dynamic adjustment is adopted. Compared with the traditional fixed contouring positioning head that needs to be matched with the workpiece model one by one, the adaptability is significantly improved. Moreover, this design can reduce the number of special tooling to be prepared. There is no need to process and customize the positioning head for each specification of filler block. It can reduce the manufacturing cost and inventory management cost of tooling to a certain extent and is suitable for multi-variety and small-batch production scenarios.

[0016] (2) By setting the first drive component and the second drive component, the present invention realizes that when the ball block body is being changed, the operator does not need to manually disassemble and replace the fixture head and recalibrate the tool. Only the feed stroke of the lead screw needs to be adjusted to complete the size change of the contour positioning port. This helps to shorten the preparation cycle for production changeover, reduce downtime, and avoid the reference offset problem caused by repeated disassembly and assembly of the fixture, which is conducive to maintaining the stability of the machining accuracy. In addition, during the positioning process, the contour positioning design ensures that each limiting surface only fits against the side of the ball filler block workpiece without applying additional squeezing or clamping force. This not only ensures that the multi-faceted constraint stably restricts the displacement of the workpiece and guarantees the uniformity of the positioning reference, but also effectively avoids the elastic deformation caused by rigid clamping to irregularly shaped parts, reduces the chamfer position deviation caused by clamping deformation, and improves the processing consistency of the ball filler block workpieces in the same batch.

[0017] (3) The present invention, through the double-sided chip removal mechanism, realizes that the two single-sided suction components are respectively set on the sides of the two grinding discs. With the negative pressure generated by the suction fan, the metal chips and abrasive particles that fall off the grinding wheel generated during the processing can be promptly removed from the processing area. After being intercepted by the filter plate, they are collected in the collection chamber. This can effectively reduce the accumulation and repeated splashing of chips and abrasive particles in the processing area, reduce the probability of hard particles scratching the chamfered surface, help improve the processing smoothness and appearance qualification rate of the chamfered surface, and improve the problem of poor chip removal in the narrow space caused by the close arrangement of the two grinding discs.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0024] For the implementation examples, please refer to the appendix. Figure 1 -Appendix Figure 18As shown, an automated grinding and chamfering device for bearing filler blocks includes a worktable 1, on which a grinding mechanism 2 and a lifting mechanism 3 are provided. The output end of the lifting mechanism 3 is provided with a contour clamping mechanism 4 for positioning the filler block body 6. The contour clamping mechanism 4 includes a base plate 41 and a cover 42, which are connected by bolts. The cover 42 has a limiting port 421, within which are two deflection limiting blocks 43 and one push-pull limiting block 44. Each deflection limiting block 43 has a rotating shaft 45, with both ends of the rotating shaft 45 rotatably connected to circular holes on the base plate 41 and the cover 42, respectively. Each deflection limiting block 43 includes a first limiting surface 431, a guide surface 432, and a first fitting opening 433. The push-pull limiting block 44 has a second limiting surface 441 on the side near the filler block body 6. A second fitting opening 442 is provided on the limiting surface 441. The second fitting opening 442 cooperates with the first fitting opening 433. The second limiting surface 441 and the two first limiting surfaces 431 together form a contour positioning opening for positioning the filler block body 6. The cover 42 and the bottom plate 41 are provided with corresponding rectangular openings 422. A double-sided chip removal mechanism 5 is provided on the lower side of the bottom plate 41. The double-sided chip removal mechanism 5 includes a housing 51 and a cover 52. The cover 52 is provided with two single-sided suction components 53. The single-sided suction component 53 includes a rectangular channel 531, a detachable cover plate 532, and multiple blades 533 with shafts. The rectangular channel 531 passes through the corresponding rectangular opening 422. The blades 533 are evenly distributed in the cover plate 532, and the blades 533 face the chamfered side of the filler block body 6. The cover plate 532 is installed on the upper end of the rectangular channel 531 by bolts.

[0025] The specific operation is as follows: First, the ball filler block body 6 to be processed is placed into the positioning port, and the side of the ball filler block body 6 that needs to be ground and chamfered faces the grinding disc 24. Then, the first motor 72 is turned on and the first lead screw 77 is driven to rotate. Subsequently, the first nut seat 771 on the first lead screw 77 drives the moving plate 71 to move linearly to the side of the first motor 72 through the receiving block 75. The two guide rollers 74 on the moving plate 71 simultaneously contact and press with the guide surfaces 432 on the two deflection limiting blocks 43, so that the two deflection limiting blocks 43 deflect around the corresponding rotating shaft 45 to the side of the ball filler block body 6 until the first limiting surface 431 on the deflection limiting block 43 is in contact with it (no pressing is required), and the reset torsion spring 46 is deformed. Subsequently, the second motor 84 drives the second lead screw 85 to rotate. The second nut seat 851 on the second lead screw 85 drives the sliding seat 81 to move linearly. Then, the sliding seat 81 pushes the back of the push-pull limiting block 44 through the bending plate 83, so that the first limiting surface 431 of the push-pull limiting block 44 can fit with the back of the filling block body 6 (no need to squeeze). At the same time, due to the sliding fit between the second fitting port 442 on the push-pull limiting block 44 and the first fitting port 433 on the deflection limiting block 43, the push-pull limiting block 44 will not interfere with the deflection limiting block 43 within a reasonable range of movement. After fitting with the back of the filling block body 6, the second limiting surface 441 of the push-pull limiting block 44 and the first limiting surfaces 431 of the two deflection limiting blocks 43 together form a contour positioning port that is adapted to the size of the filling block body 6, avoiding the need to change different positioning heads when positioning filling block bodies 6 of different specifications in the same series. After the ball filler block body 6 is contoured and positioned, the third motor 35 is turned on to drive the third lead screw 32 to rotate. Subsequently, with the cooperation of the slide rod 33 and the slider 331, the third nut seat 321 drives the ball filler block body 6 to move upward through the lifting seat 34, so that the two chamfered edges of the ball filler block body 6 contact the two grinding discs 24 respectively (the ball filler block body 6 is in the center). Then, the fourth motor 23 drives the grinding discs 24 to rotate (the rotation direction of the grinding discs 24 is downward towards the side of the ball filler block body 6, which will give the ball filler block body 6 a downward component force to ensure that the ball filler block body 6 is stably located in the contour positioning opening). The two sides of the ball filler block are chamfered at the same time. The size of the chamfer can be adjusted by controlling the rising range of the lifting seat 34. Simultaneously, the suction fan 54 starts, and the blades 533 on the rectangular channels 531 of the two single-sided suction components 53 respectively suck up the two nearby grinding discs 24. As a result, the metal shavings and abrasive particles that fall off the grinding discs 24 generated during grinding are sucked into the corresponding single-sided suction component 53, and fall into the collection chamber 511 under the blocking of the filter plate 55, and are collected in a concentrated manner. This avoids the problem of shavings and abrasive particles repeatedly splashing in a narrow space and not being able to be discharged in a short time, causing accumulation and scraping of the chamfered surface. After the chamfering is completed, the third motor 35 reverses and drives the lifting seat 34 to move down. Then, the staff can take out the processed filling block body 6 from the contour positioning port.
