[0002] Automotive bearings are key basic components in automobiles, installed in multiple parts such as wheels, transmissions, and engines. They play an important role in supporting and guiding the rotation of automobiles. They are generally composed of inner rings, outer rings, rolling elements, and cages. Different types of automotive bearings (such as deep groove ball bearings and tapered roller bearings) have slightly different structures to adapt to different working environments and load requirements.

[0003] The machining process of the inner wheel of an automotive bearing involves raw material preparation, forging, turning, heat treatment, grinding, and finishing. During finishing, the vehicle needs to be positioned.

A support column 17 is fixedly connected to the top of the top plate 16. A pair of first fixed seats 18 are fixedly connected to the outer wall of the support column 17. A first support rod 19 is fixedly connected inside the first fixed base 18; a second fixed base 101 is connected to the end of the first support rod 19; a clamping plate 102 is fixedly connected to the side wall of the second fixed base 101; a second support rod 106 is slidably connected to the end of the second fixed base 101; a first sliding groove 103 is opened inside the support column 17; a first slider 104 is provided inside the first sliding groove 103; the first sliding groove 103 and the first slider 104 are slidably connected; a pair of third fixed bases 105 are fixedly connected to the top of the first slider 104; a pair of The third fixed seat 105 is internally provided with a second support rod 106. When the inner wheel of the car bearing is placed on the support column 17, it will then contact the clamping plate 102. At this time, the cylinder 11 can be activated, causing the iron plate 12 to move. Simultaneously, the cylinder 13 at the top of the iron plate 12 will also move, and then the cylinder 13 will abut against the push-pull ring 14. The push-pull ring 14 will then cause the first slider 104 at the bottom of the third fixed seat 105 to slide within the first slide groove 103. At this time, the second support rod 106 will also move accordingly. As the second support rod 106 slides upward, the clamping plate 102 on the top of the second fixed seat 101 gradually moves to both sides. After the clamping plate 102 completely abuts against the inner wheel of the car bearing, the cylinder 11 is closed. By adding the cylinder 11, the positioning position of the clamping plate 102 on the inner wheel of the car bearing can be changed.

Block 22 slides inside the second slide groove 21. During the sliding, the clamping frame 27 also moves. After the clamping frame 27 is moved to the inner wheel of the car bearing, it stops. Then, the insert rod 25 is rotated, and the insert rod 25 rotates inside the slot 26, thereby moving downward against the pressure plate 2. At this time, the spring 24 will also extend and retract. After the pressure plate 2 locks the top of the inner wheel of the car bearing, the insert rod 25 can be released. By adding the pressure plate 2, the top and bottom of the inner wheel of the car bearing can be positioned after it is clamped by the clamping plate 102, reducing the possibility of it slipping off the clamping plate 102 during the processing of the inner wheel of the car bearing, and further improving the positioning of the inner wheel of the car bearing.

[0029] like Figures 4 to 5As shown, a chip collection groove 51 is fixedly connected to the top of the top plate 16; multiple magnetic pillars 5 are arranged inside the chip collection groove 51; when machining the inner wheel of the automobile bearing, some chips will fall off. At this time, the chips will fall into the chip collection groove 51, and then the metal chips will be attracted by the magnetic pillars 5; by adding magnetic pillars 5, metal chips and ordinary chips can be separated, making it easier to handle the chips later, and also reducing the situation where dust and chips fall onto the top of the top plate 16.

[0031] Working principle: Place the inner wheel of the car bearing onto the support column 17. The inner wheel will then contact the clamping plate 102. At this time, the cylinder 11 can be activated, which will drive the iron plate 12 to move. At this time, the cylinder 13 on the top of the iron plate 12 will also move. Then, the cylinder 13 will abut against the push-pull ring 14. The push-pull ring 14 will drive the first slider 104 at the bottom of the third fixed seat 105 to slide inside the first slide groove 103. At this time, the second support rod 106 will also slide. The second support rod 106 slides upward, and then the clamping plate 102 on the top of the second fixed seat 101 will gradually move to both sides. After the clamping plate 102 completely abuts against the inner wheel of the car bearing, the cylinder 11 can be closed. After the clamping plate 102 fixes the inner wheel of the car bearing, the second slider 22 can be slid. The second slider 22 will then slide inside the second slide groove 21. When sliding, the clamping frame 27 will also move, moving the clamping frame 27 to... After the inner wheel of the car bearing stops, the insert rod 25 is rotated. The insert rod 25 then rotates inside the slot 26, thus moving downward against the pressure plate 2. At this time, the spring 24 also extends and retracts. After the pressure plate 2 locks the top of the inner wheel of the car bearing, the insert rod 25 is released. After the inner wheel of the car bearing is processed, the water inlet 31 can be connected to the water pump. Then the water pipe 3 will start spraying water to cool the inner wheel of the car bearing. After the inner wheel of the car bearing is fixed by the clamping plate 102, the air inlet 41 can be connected to the air pump. Then the air pipe 4 will start blowing air onto the surface of the inner wheel of the car bearing. During the processing of the inner wheel of the car bearing, some debris will fall. The debris will fall into the chip collection groove 51. Then the metal debris will be attracted by the magnetic column 5. When the clamping plate 102 clamps the inner wheel of the car bearing, the rubber pad 6 will preferentially contact the inner wheel of the car bearing, reducing the contact area between the clamping plate 102 and the inner wheel of the car bearing.
