Description

Technical Field

[0001] This invention relates to the field of gear grinding technology, and specifically to a gear inner ring grinding device. Background Technology

[0002] As the core component of a mechanical transmission system, the inner ring dimensional accuracy and surface flatness of gears directly determine transmission efficiency, meshing stability, and equipment lifespan. Therefore, gear inner ring grinding is one of the key processes in gear processing. Currently, the mainstream gear inner ring grinding equipment in the industry fixes the outer ring of the gear through an external clamping structure, uses a rotating component to drive the gear to rotate at high speed, and then controls the grinding tool to move towards the inner ring of the gear to achieve the inner ring grinding operation. However, existing equipment, relying solely on outer ring clamping, cannot accurately guarantee that the shaft center of the gear after clamping is completely aligned with the rotation shaft center of the rotating component, which easily leads to shaft center misalignment. During the grinding process, this misalignment will cause uneven force on the inner ring of the gear, resulting in defects such as out-of-tolerance hole diameter, uneven inner wall, and inconsistent grinding thickness, which seriously affects the product qualification rate. Therefore, a gear inner ring processing and grinding device that can accurately guarantee the coaxiality of the gear and the rotating component, stable clamping, and strong adaptability is needed to improve the accuracy and efficiency of gear inner ring grinding. Summary of the Invention

The inner clamping component moves together with the lifting component as it rises. When the inner clamping component and the rotating component come into contact, the lifting component continues to move in the same direction, so that the inner clamping component opens to clamp the inner ring of the gear, ensuring that the gear and the rotating component are coaxial. The transmission component is driven by a conductive component to control the movement of the inner clamping component; The guiding component is driven by a conductive component to control the movement of the external clamping component; The outer clamping assembly clamps the outer ring of the gear under the guidance of the guide assembly, while the inner clamping assembly positions the inner ring of the gear during the clamping process to prevent the shaft center from shifting. After the outer clamping component is fixed, the inner clamping component moves together with the lifting component as it descends. The lifting component drives the inner clamping component to retract to the inside of the rotating component, thus avoiding interference with the grinding of the inner ring of the gear.

[0023] Please see Figure 5 - Figure 8 The present invention provides a technical solution: the transmission component 4 includes a rotating bearing 401, an internal toothed fixing ring 402 and an annular fixing plate 403.

The external clamping assembly 7 includes a clamping mounting block 701, a clamping limiting block 702, a fixed constraint plate 703, a fixed guide groove 704, and a clamping guide post 705. The clamping mounting block 701 is fixedly mounted on the side of the rotating mounting base 101 containing the positioning hollow post 106. The clamping mounting block 701 has at least four fixed guide grooves 704. A clamping guide post 705 is fixedly provided inside each fixed guide groove 704. A clamping limiting block 702 is fixedly provided at the end of each clamping guide post 705 away from the rotating assembly 1.

[0025] Please see Figure 2 - Figure 8 The present invention provides a technical solution: three rotating screws 10 and rotating gears 11 are movably provided inside the rotating connecting cavity 104. Each rotating gear 11 is fixedly installed on the rotating screw 10. The rotating gear 11 meshes with the internal gear fixing ring 402. The rotating screw 10 is sleeved on the lifting connecting arm 202 and meshes with the inner wall of the lifting connecting arm 202.

The grinding connecting table 1302 is fixedly provided on the upper surface of the grinding assembly 13. The bidirectional moving table 1303 is movably provided on the upper surface of the grinding connecting table 1302. The grinding tool 1304 is fixedly provided on one side of the bidirectional moving table 1303. The fixed mounting plate 1305 is fixedly provided on the grinding assembly 13. A rotating mounting seat 101 is movably provided on the side of the fixed mounting plate 1305 near the grinding tool 1304. The axes of the rotating mounting seat 101 and the grinding tool 1304 are on the same axis.

[0026] In specific implementation: When gears need to be processed, the drive motor 603 that can drive the lifting gear 604 to rotate is first started. The power is transmitted to the lifting gear 604 through the output shaft. The lifting gear 604 meshes with the outer wall of the annular fixed plate 403 on the transmission component 4, thereby driving the annular fixed plate 403 to rotate. The annular fixed plate 403 is fixedly connected to the internal gear fixed ring 402, so it can synchronously drive the internal gear fixed ring 402 to rotate around the rotating bearing 401. The internal gear fixed ring 402 meshes with the three rotating gears 11, driving the three rotating gears 11 to rotate synchronously, thereby driving the rotating screw 10 on its axis to rotate in the rotating connecting cavity 104. The lifting connecting arm 202 has an internal thread on its inner side. The rotating screw 10 meshes with the thread on the inner wall of the lifting connecting arm 202 of the lifting component 2, converting the rotational motion into the linear motion of the lifting connecting arm 202, and finally driving the entire lifting component 2 to move along the telescopic positioning cavity 102, providing power for the clamping action of the inner clamping component 3.

[0027] The operator holds the gear 12 to be processed and places it stably in the inner area of ​​the outer clamping component 7, aligning the inner ring of the gear 12 with the positioning hollow column 106 of the rotating component 1, ensuring that the gear is roughly centered. Current flows through the conductive connector 9, the conductive outer ring 8 and the conductive inner ring 601. The conductive inner ring 601 of the conductive component 6 supplies power to the two drive motors 603 through the wires inside the insulating fixing tube 602. The equipment enters the standby state. At this time, the inner clamping component 3 is in the retracted state inside the telescopic positioning cavity 102, and the clamping mounting block 701 of the outer clamping component 7 is in the open state and does not contact the gear 12 to be processed.

[0028] The drive motor 603 connected to the lifting gear 604 is started, causing the lifting gear 604 to start rotating. This drives the lifting assembly 2 to move along the telescopic positioning cavity 102. The clamping constraint block 303 of the inner clamping assembly 3 is movably connected to the guide support block 204 of the lifting assembly 2 through the inclined clamping constraint groove 304. When the lifting assembly 2 rises, under the action of friction, the guide support block 204 moves while the clamping arc block 301 slides under the constraint of the clamping constraint groove 304, causing the clamping arc block 301 to move away from the axis of the rotating mounting seat 101. This allows multiple clamping arc blocks 301 to move away from each other and spread out in the telescopic positioning cavity 102. Therefore, the return spring 305 is needed to balance the friction so that the inner clamping assembly 3 can smoothly pass through the inner ring of the gear 12 to be processed in the retracted state.

[0029] As the lifting assembly 2 continues to rise until one side of the limit support block 302 abuts against the positioning constraint block 107, the inner clamping assembly 3 is precisely at the center of the inner ring of the gear 12 to be processed. Subsequently, the lifting assembly 2 continues to rise, thereby continuously compressing the return spring 305. When the support block 204 moves, the clamping arc block 301 will slide under the constraint of the clamping constraint groove 304, causing the clamping arc block 301 to move away from the axis of the rotating mounting base 101. This allows multiple clamping arc blocks 301 to move away from each other, pushing the clamping arc blocks 301 to open outwards until they are tightly fitted with the inner ring of the gear 12 to be processed. The center of the lifting assembly 2 is completely aligned with the axis of the rotating assembly 1, and the inner clamping assembly 3 is precisely connected to the lifting assembly 2. Therefore, after the gear 12 to be processed is clamped, its axis is consistent with the rotation axis of the rotating assembly 1.

[0030] Then another drive motor 603 is started, and the power is transmitted to the constraint gear 605 through the output shaft. The constraint gear 605 meshes with the rotating toothed plate 504 of the guide assembly 5, driving the guide rotating block 502 to rotate in the constraint connecting cavity 105. The guide rotating block 502 is fixedly connected to the guide connecting plate 501, so it synchronously drives the guide connecting plate 501 to rotate. The shortest path lengths from the two ends of the guide constraint groove 505 on the guide connecting plate 501 to the edge of the guide connecting plate 501 are different. Therefore, when the guide connecting plate 501 rotates, it will generate a lateral thrust on the clamping guide post 705. The fixed guide grooves 704 on the fixed constraint plate 703 overlap vertically, and the clamping guide post 705 is embedded in the overlapping area. When the guide connecting plate 501 rotates, it pushes the clamping guide post 705 to move along the fixed guide groove 704 towards the axis, thereby driving the clamping mounting block 701 to move towards the center synchronously, clamping the outer ring of the gear 12 to be processed. After the clamping mounting block 701 clamps the gear 12 to be processed, the drive motor 603 can still continuously output a constant torque to the constraint gear 605, so that the constraint gear 605 drives the guide connecting plate 501 to continuously keep the clamping mounting block 701 clamped.

[0031] If the outer surface of the gear 12 to be processed is not smooth, only two or three of the clamping mounting blocks 701 in the four directions may contact the outer ring of the gear. Since the clamping mounting blocks 701 are curved and the inner surface is not smooth, the friction with the outer ring of the gear is increased. At the same time, relying on the coaxial reference pre-positioned by the inner clamping component 3, even if not all clamping mounting blocks are in contact, the axis of the gear 12 to be processed can be guaranteed not to deviate, avoiding the axis deviation problem caused by traditional full clamping.

[0032] After the outer clamping component 7 is fixed, the lifting gear 604 is rotated in the opposite direction by the drive motor 603 to reset the lifting component 2. When the guide support block 204 moves, the reset spring 305 releases its elastic force, causing the clamping arc block 301 to retract only inward and not move with the lifting component 2. After the reset spring 305 releases its elastic force, the inner clamping component 3 returns to the telescopic positioning cavity 102 with the lifting component 2 to avoid interfering with the inner ring grinding.

[0033] This completes the clamping of the gear 12 to be processed. Then, the grinding assembly 13 is started to grind the inner ring. During the grinding process, the fixed constraint plate 703 and the clamping mounting block 701 form a rigid support to ensure that the gear does not loosen or deviate during the high-speed rotation grinding process.

[0034] The counterweight 503 serves to balance the weight imbalance caused by the rotating toothed plate 504, ensuring the overall rotation of the rotating mounting base 101 is stable. By offsetting the weight imbalance of the rotating toothed plate 504 with its own weight, it allows the center of gravity of the rotating mounting base 101 to return to the axis, preventing wobbling caused by the center of gravity shift during rotation.

[0035] After grinding is completed, the constant torque continuously applied by the drive motor 603 is released, and the motor rotates in the opposite direction, causing the clamping mounting block 701 to retract to its initial position. The gear is then removed to complete the entire grinding process.

[0036] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
