Description

Technical Field

[0001] The invention relates to the technical field of automobile parts processing, in particular to a positioning tool for processing an ABS gear ring of an automobile part. Background Art

[0002] The ABS ring gear is an important component in the anti-lock braking system (ABS) of the car. It is usually installed on the inner side of the wheel hub and used in conjunction with the sensor fixed on the axle. The ABS ring gear is generally in the shape of a spur gear, including an outer tooth surface and an inner ring surface, and the outer tooth surface and the inner ring surface are hollow. This structural design reduces material consumption while ensuring that it can be matched with traditional sensors, achieving the purpose of lightweighting the ring gear.

[0003] After searching, it was found that the patent document with publication number CN117984223A provides a low-rigidity thin-walled gear ring end face grinding tool, in which the gear ring is clamped on an electric permanent magnetic chuck by three arc-shaped clamping blocks. After the gear ring is fixed, the end face of the gear ring is detected by a flatness measuring device and the end face is polished accordingly. After each end face is processed, the gear ring needs to be removed, turned over and re-fixed. Only one face is processed each time, and the flatness of the end face needs to be measured multiple times during processing. The gear ring grinding efficiency is low. At the same time, when the prior art is grinding the gear ring end face, if the gear ring is rotated at a constant speed, the linear velocity of the gear ring end face from the inside to the outside will gradually increase, and the outer edge of the end face will rub against the polishing disk more frequently. At this time, the outer edge of the end face will be ground more than the inner edge, and the outer edge of the end face will collapse slightly while the inner edge will warp accordingly. To solve this problem, a positioning tool for processing ABS gear rings of automotive parts is proposed, which can polish both sides of the ABS gear ring at the same time, improve the polishing efficiency and eliminate processing problems such as edge collapse and warping of the gear ring end face.

When the first internal gear ring 153 rotates, it will drive the other first internal gears 158 to rotate synchronously in the same direction. At this time, the rack 159 located on one side of the multiple first internal gears 158 will slide in the guide groove 157, and accordingly, the fan-shaped clamping plate 152 connected to the rack 159 will move inward or outward.

During the revolution of the gear ring 151 to be processed, the linear speed of its upper and lower end surfaces from the inside to the outside will gradually increase, and the outer edge of the end surface will rub against the polishing disk more frequently. At this time, the outer edge of the end surface is relatively The inner edge will be ground more, the outer edge of the end face will collapse slightly and the inner edge will warp accordingly. This processing problem is common in existing polishing equipment. To solve this problem, the gear ring can be rotated by a combination of revolution and rotation after the revolution processing is completed, and the gear ring can be ground and polished for the second time. The outer edge of the original gear ring is adjusted to the inner edge through the rotation of the gear ring, and the inner edge is turned to the original outer edge position. By adjusting the position and angle between the end face of the gear ring and the polishing disk, the grinding position is changed multiple times, so that the end face of the gear ring can be ground flat and the problems of collapsed edges and warped corners can be eliminated.

When the active end face ratchet 1763 at one end of the first connecting rod 1761 rotates clockwise, it will drive the driven end face ratchet to rotate synchronously, so that the second connecting rod 1764 and the first shaft 17 connected to the second connecting rod 1764 can rotate clockwise. 1 rotates synchronously clockwise, the first rotating shaft 171 is connected to the second outer gear 164, and the second outer gear 164 is meshed with the second outer gear ring 163. When the first rotating shaft 171 rotates, the second outer gear ring 163 will rotate synchronously and drive the second inner gear ring 161 connected thereto to rotate synchronously. At this time, the second inner gear ring 161 and the differential gear 165 in the differential mechanism 16 rotate synchronously in the same direction. The positioning mechanism 15 meshedly connected between the second inner gear ring 161 and the differential gear 165 will only revolve in the polishing area 166 under the clamping of the teeth on both sides. At this time, the revolution speed is relatively fast, and the gear ring 151 to be processed in the positioning mechanism 15 can be quickly rough-polished; When the revolution and rotation combination is rotating and grinding, the second motor 174 is controlled to output in the reverse direction to drive the second shaft 173 to rotate counterclockwise. The second shaft 173 located on the upper side drives the differential gear 165 to rotate counterclockwise. The second shaft 173 located on the lower side drives the second bevel gear 175 to rotate counterclockwise. The second bevel gear 175 is meshed with the main transmission bevel gear 1762, which will drive the first connecting rod 1761 to rotate counterclockwise. When the first connecting rod 1761 rotates counterclockwise, the active end face ratchet 1763 will squeeze the driven end face ratchet 1766, and the driven end face ratchet 1766 cannot rotate, and accordingly, it cannot drive the second connecting rod 1764 to rotate. When the second connecting rod 1764 does not rotate, the first shaft 171 will not rotate either. At this time, the second external gear 164 connected to the first shaft 171 will remain stationary. When the second outer gear 164 is stationary, the second outer gear ring 163 and the second inner gear ring 161 will remain stationary. At this time, only the differential gear 165 in the differential mechanism 16 rotates counterclockwise, and the first outer gear ring 155 in the positioning mechanism 15 is meshed and connected between the second inner gear ring 161 and the differential gear 165. When the second inner gear ring 161 is stationary and the differential gear 165 rotates, the first outer gear ring 155 will lead the entire positioning mechanism 15 to perform rapid self-rotation and synchronous slow revolution in the polishing area 166, so that the gear ring 151 to be processed located in the positioning mechanism 15 can perform a combination of revolution and self-rotation. The position and angle between the end face of the gear ring and the polishing disk are adjusted by the combined rotation, and the grinding position is changed multiple times, so that the end face of the gear ring can be polished flat, eliminating processing problems such as collapsed edges and warped corners.
