Planetary gears are mostly processed by adopting a worm grinding wheel gear grinding machine, and the involute shape of gear teeth is ground by continuously meshing a grinding wheel with a worm shape with the gear by utilizing a gear grinding method based on a meshing cutting principle. The method is one of the methods with higher efficiency in the tooth grinding process, has highest efficiency in batch tooth grinding processing of small and medium modulus gears, and is most widely applied.

Two groups of upper connecting rotating rods 512 are symmetrically arranged on the top side wall of the clamping main rod 51, and four groups of movable sliding rods 511 are circumferentially arranged on the top side wall of the clamping main rod 51. The four movable slide bars 511 are disposed equidistant from the two upper connecting rods 512 and along the axis of the side wall of the main clamping rod 51. One end of each group of movable slide bars 511, which is far away from the side wall of the clamping main rod 51, is connected with the conveying inner roller 435, and one end of each group of upper connecting rotating bars 512, which is far away from the side wall of the clamping main rod 51, is rotatably connected with the transmission module 436. The four groups of movable slide bars 511 are respectively adapted in length and shape to the clamping slide grooves 4351, and are slidably mounted inside the clamping slide grooves 4351. The movement of the holding unit 5 in the vertical direction can be achieved by the movement of the moving slide 511 inside the holding slide 4351. The clamping unit 5 is connected with the transmission module 436 through the upper connecting rotating rod 512, and the clamping unit 5 can be synchronously driven to move through the upper connecting rotating rod 512 in the motion process of the transmission module 436.
Referring to fig. 6-7 and fig. 9-10, a telescopic inner rod 52 is inserted into the clamping main rod 51, and the telescopic inner rod 52 is disposed along a vertical direction and can move along the vertical direction relative to the clamping main rod 51. A group of micro air cylinders 53 are arranged at the top of the telescopic inner rod 52, and the micro air cylinders 53 can drive the telescopic inner rod 52 to move along the vertical direction. The telescopic inner rod 52 bottom is connected with the cooperation base 54, and the cooperation base 54 sets up to the regular hexagon structure of shape and lower connection bull stick 513 adaptation, and along vertical direction and the coaxial setting of connection bull stick 513 down, and the cooperation base 54 can follow telescopic inner rod 52 and remove in step. The end part of the matching base 54 far away from the axis is rotatably connected with a second rotating rod 56, and the second rotating rod 56 can rotate relative to the matching base 54. Six groups of lower connecting rotating rods 513 are arranged at equal intervals on the bottom of the clamping main rod 51 in a surrounding mode, one end, far away from the side wall of the clamping main rod 51, of each group of lower connecting rotating rods 513 is rotationally connected with a group of first rotating rods 55, and the first rotating rods 55 can rotate relative to the lower connecting rotating rods 513. One end of each group of first rotating rods 55 far away from the lower connecting rotating rod 513 is rotatably connected with one end of each second rotating rod 56 far away from the matching base 54, and the first rotating rods 55 and the second rotating rods 56 can rotate relatively. A group of arc-shaped clamping pieces 57 are arranged at one side, far away from the second rotating rod 56, of the bottom of each group of first rotating rod 55, each group of arc-shaped clamping pieces 57 are arranged in the vertical direction and are made of electromagnet materials, magnetism can be generated after the arc-shaped clamping pieces 57 are electrified, so that the planetary gear 6 is adsorbed, and the side walls of the six groups of arc-shaped clamping pieces 57 are matched with the shape of the inner wall of the planetary gear 6. In the process that the matching base 54 moves downwards along the vertical direction along with the telescopic inner rod 52, through the rotation of the first rotating rod 55 and the second rotating rod 56, the arc-shaped clamping piece 57 can be opened relatively to the matching base 54, and finally the opened arc-shaped clamping piece 57 is tightly attached to the inner wall of the planetary gear 6, and the magnetism generated by electrifying the arc-shaped clamping piece 57 is matched after the arc-shaped clamping piece is tightly attached, so that the clamping of the planetary gear 6 is completed. After the bottom of the arc-shaped clamping piece 57 is pressed, the rotation of the first rotating rod 55 and the second rotating rod 56 can be used for realizing the tightening of the arc-shaped clamping piece 57 relative to the matching base 54, and meanwhile, the whole clamping unit 5 can be driven to move upwards in the clamping chute 4351, so that the resetting of the clamping unit 5 is completed.
Specifically, before the planetary gear 6 is clamped, the driving device at the bottom of the rotating base 41 drives the rotating base 41 to rotate, and synchronously drives the conveying support 42 to rotate, so that the conveying roller assembly 43 mounted on the conveying support 42 moves to the top of the planetary gear 6 to be ready for the next step of clamping.
After the conveying roller assembly 43 is in place, the first conveying roller 431 is driven to move downwards by a driving device inside the conveying roller assembly 43. When the bottom of the outer conveying roller 432 is abutted against the top of the planetary gear 6, the first conveying roller 431 continuously moves downwards to compress the abutting spring 434, and the abutting spring 434 drives the inner conveying roller 435 to continuously move downwards to enter the inner side wall of the planetary gear 6. At this time, the conveying outer roller 432 slides in the vertical direction with respect to the conveying inner roller 435, and the outer fitting through hole 4331 provided in the conveying outer roller 432 is displaced in synchronization with the inner fitting through hole 4332 provided in the conveying inner roller 435.
The change of the relative positions of the outer matching through hole 4331 and the inner matching through hole 4332 can make the first telescopic rod 4362 rotate relative to the outer roller transmission seat 4361, and further drive the inner roller rotating rod 4363 to rotate. In the rotation process of the inner roller rotating rod 4363, the second telescopic rod 4364 is synchronously driven to rotate. The second telescopic rod 4364 is extended simultaneously in the rotation process, and finally, the clamping unit 5 is synchronously driven to move downwards through the upper connecting rotating rod 512 under the double adjustment of the angle and the length. In the process of downward movement of the clamping unit 5, the movable slide bar 511 synchronously moves downward in the clamping slide groove 4351, and finally the arc-shaped clamping piece 57 at the bottom of the clamping unit 5 moves to the bottom of the conveying inner roller 435 to be ready for clamping the planetary gear 6.
After the arc-shaped clamping piece 57 completely enters the planetary gear 6 downwards, the micro air cylinder 53 drives the telescopic inner rod 52 to move downwards along the vertical direction, and synchronously drives the matching base 54 at the bottom of the telescopic inner rod 52 to move. In the process that the matching base 54 moves downwards along with the telescopic inner rod 52, the arc-shaped clamping piece 57 is opened relative to the matching base 54 through the rotation of the first rotating rod 55 and the second rotating rod 56. After the arc-shaped clamping piece 57 is opened and tightly attached to the inner wall of the planetary gear 6, the arc-shaped clamping piece 57 is electrified, and the clamping of the planetary gear 6 is completed by utilizing magnetism generated by the arc-shaped clamping piece 57. Because the inner wall of the planetary gear 6 is very smooth and flat, the tension generated by the fact that the arc-shaped clamping piece 57 is attached to the inner wall of the planetary gear 6 after being opened is insufficient to ensure the reliability of clamping, the magnetism generated by electrifying the arc-shaped clamping piece 57 is further utilized to ensure the reliability of adsorption between the arc-shaped clamping piece 57 and the planetary gear 6, and the phenomenon that the planetary gear 6 slips in the subsequent conveying process is effectively avoided, so that the planetary gear 6 is damaged is avoided.
After the arc-shaped clamping piece 57 is clamped, the conveying support 42 and the conveying roller assembly 43 are synchronously driven to continue to rotate through the rotation of the rotary base 41, and finally the planetary gear 6 clamped by the arc-shaped clamping piece 57 reaches the position of the matching seat 32, the planetary gear 6 is placed at the top of the matching seat 32, and conveying of the planetary gear 6 is completed.
Referring to fig. 1-5 and fig. 11-12, the second embodiment is modified on the basis of the first embodiment in that a positioning lifting block 34 is disposed in the base mounting member 31 along the vertical direction, a positioning chuck 33 is mounted on top of the positioning lifting block 34, and the positioning lifting block 34 can drive the positioning chuck 33 to move along the vertical direction. The positioning chuck 33 is of a cylindrical structure with an outer diameter adapted to the inner diameter of the planetary gear 6 and is coaxially arranged with the mating seat 32, and the positioning chuck 33 can penetrate through the mating seat 32 to enter the planetary gear 6 in the process of moving upwards in the vertical direction. Three groups of movable sliding grooves 332 are symmetrically formed in the top of the positioning chuck 33 around the central position, a group of movable clamping jaws 331 are slidably connected to the top of each group of movable sliding grooves 332, and the movable clamping jaws 331 can slide along the movable sliding grooves 332.
Referring to fig. 5, a positioning chute 4352 is formed at the bottom of the inner sidewall of the conveying inner roller 435 along the vertical direction, and three groups of positioning chutes 4352 are equidistantly disposed around the inner sidewall of the conveying inner roller 435. The angle and the interval between every two groups of positioning sliding grooves 4352 are matched with the two groups of movable clamping jaws 331, and the shape of each group of positioning sliding grooves 4352 is matched with the movable clamping jaw 331. After the positioning chuck 33 moves upwards to pass through the planetary gear 6 and enter the conveying inner roller 435, the positions of the three groups of moving clamping jaws 331 respectively correspond to the three groups of positioning sliding grooves 4352, and the three groups of moving clamping jaws 331 can be inserted into the positioning sliding grooves 4352 in the process of moving along the moving sliding grooves 332 to the side far from the center of the positioning chuck 33.
Specifically, after the planetary gear 6 is conveyed to the top of the matching seat 32 by the clamping unit 5 and placed, the arc-shaped clamping piece 57 is not electrified, so that the follow-up arc-shaped clamping piece 57 is conveniently separated from the planetary gear 6. The positioning lifting block 34 drives the positioning chuck 33 to move upwards in the vertical direction, and after the positioning chuck 33 passes through the matching seat 32 and enters the planetary gear 6, the tops of the three groups of moving clamping jaws 331 are respectively abutted with the bottom of the matching base 54. In the process of continuing to move upwards, the positioning chuck 33 is connected with the matching base 54 through the arc-shaped clamping piece 57, so that the matching base 54 and the telescopic inner rod 52 are pushed to move upwards synchronously, and finally the movable sliding rod 511 is driven to move upwards in the clamping sliding groove 4351, so that the whole clamping unit 5 moves upwards. The clamping unit 5 moves upwards in a resetting way and simultaneously drives the first rotating rod 55 and the second rotating rod 56 to rotate through the upward movement of the matched base 54, so that the arc-shaped clamping piece 57 is tightened relative to the matched base 54. The clamping unit 5 is tightened and separated from the inside of the planetary gear 6, and after the clamping of the planetary gear 6 is released, the resetting of the clamping unit 5 is completed.
In the process of resetting the clamping unit 5, the three groups of moving clamping jaws 331 at the top of the positioning chuck 33 can not only realize the abutting of the arc-shaped clamping piece 57, but also keep collineation with the positioning sliding groove 4352 inside the conveying inner roller 435 in the moving process. After the clamping unit 5 resets and releases the clamping of the planetary gear 6, the three groups of moving clamping jaws 331 respectively move along the moving sliding grooves 332 to a side far away from the center of the positioning chuck 33, and finally enter the positioning sliding grooves 4352. The positioning chuck 33 and the conveying inner roller 435 are integrally connected, so that the positioning chuck 33 and the conveying inner roller 435 limit the planetary gear 6 from the top and the bottom, respectively. The positioning chuck 33 and the conveying inner roller 435 are connected into a whole, so that detachment in the circumferential direction can be avoided in the gear grinding process, the positioning chuck 33 and the conveying inner roller 435 can respectively limit the planetary gear 6 from the top and the bottom, and the shift of the gear grinding position of the planetary gear 6 caused by the stress shift of the planetary gear 6 in the subsequent gear grinding process can be effectively avoided, so that the processing quality of the planetary gear 6 is ensured.

The gear grinding running assembly 24 comprises a running mounting piece 241 which is arranged in a rectangular structure, a gear grinding motor 242 is mounted on the top of the running mounting piece 241, and a gear grinding worm 243 is mounted on the side wall of the running mounting piece 241, which is close to the side wall of the base unit 3. The gear grinding worm 243 is provided in a spiral structure and is shaped to fit the planetary gear 6. The gear grinding motor 242 can drive the gear grinding worm 243 to rotate, thereby completing the gear grinding process of the planetary gear 6.
Specifically, after the positioning chuck 33 is inserted into the conveying inner roller 435 to connect the base unit 3 and the conveying unit 4, the gear grinding running assembly 24 is driven by the gear grinding slide rail 23 to move along the length direction of the gear grinding sliding seat 22, so that the gear grinding worm 243 on the side wall of the running mounting piece 241 is close to the planetary gear 6. After the gear grinding worm 243 is attached to the side wall of the planetary gear 6, the gear grinding motor 242 drives the gear grinding worm 243 to rotate, and gear grinding of the planetary gear 6 is completed.
In the gear grinding process of the planetary gear 6, the base unit 3 and the conveying unit 4 can be integrally connected by the connection of the positioning chuck 33 and the conveying inner roller 435.
