The change or adjustment of their relative relationship, without substantial change in the technical content, should also be regarded as the scope of implementation of the present invention.

[0021] Refer to Figure 1 - Figure 2 , a grinding device for processing automobile parts, including a frame 1 arranged in a U shape and a rotating table 2 arranged in a cube shape. The frame 1 and the rotating table 2 are rotatably connected. The two sides of the rotating table 2 are fixedly connected with rotating shafts, and a first gear 3 is fixedly connected to one of the rotating shafts;

[0022] The other rotating shaft penetrates through the frame 1 and a pointer 4 is fixedly installed on the end face. A collision column 5 is fixedly installed at the end of the pointer 4. An arc-shaped plate integrated with the frame 1 is arranged on one side of the frame 1, and angle scale lines 6 are engraved on one side of the arc-shaped plate. A flat plate and a baffle are fixedly arranged on one side of the frame 1. A ratchet tooth 25 is fixedly arranged on the upper end of the flat plate, and an elastic cord 18 is fixedly installed on the surface of the baffle. The other end of the elastic cord 18 is fixedly connected with a limit box 17. The limit box 17 is slidably connected with the flat plate. A gear roller 21 is rotatably installed on the inner wall of the limit box 17. The upper side of the gear roller 21 is meshed with a first toothed plate 20. One end of the first toothed plate 20 penetrates through the side wall of the limit box 17 and is fixedly connected with a collision plate 19. The lower side of the gear roller 21 is meshed with a second toothed plate 22. A spring 24 is fixedly installed on the lower end face inside the limit box 17. The other end of the spring 24 is fixedly connected with a clamping plate 23 with a cross-sectional shape of 7. The lower end of the clamping plate 23 penetrates through the lower end face inside the limit box 17 and is meshed with the ratchet tooth 25.

[0023] A round tube is fixedly arranged on the surface of the limit box 17. A guide rod 26 is slidably connected inside the round tube. The guide rod 26 is fixedly installed on the surface of the baffle. When the limit box 17 moves, the round tube and the guide rod 26 can limit the movement track of the limit box 17.

[0024] On the upper surface of the rotating table 2, a plurality of rotating rods 7 are rotatably arranged. Each rotating rod 7 penetrates through the rotating table 2. On the lower surface of the rotating table 2 where each rotating rod 7 penetrates, a secondary gear 9 is fixedly arranged. Each secondary gear 9 is meshed with the same main gear 8. The main gear 8 is rotatably installed on the lower surface of the rotating table 2. The main gear 8 is meshed with a first threaded rod 10. The first threaded rod 10 is rotatably installed on the lower surface of the rotating table 2.

[0025] The first gear 3 is meshed with a second threaded rod 11. The second threaded rod 11 is rotatably connected to the upper surface of the frame 1.

[0026] On one side of the frame 1, a limiting groove 12 is fixedly arranged. On the surface of the limiting groove 12, a vertical rod 13 is slidably connected. A sliding sleeve 14 is slidably sleeved on the surface of the vertical rod 13. On the surface of the sliding sleeve 14, a cross bar 15 is fixedly installed. On the surface of the cross bar 15, a grinding device including a grinding wheel 16 is fixedly installed. After the position of the hub is fixed, the worker holds the grinding device for operation, so that the grinding wheel 16 grinds the surface of the hub. The vertical rod 13 can move the grinding wheel 16 back and forth, and the cross bar 15 can move the grinding wheel 16 up and down.

[0027] On the end faces of the first threaded rod 10 and the second threaded rod 11, extension rods with fixed connections are arranged. At the ends of the extension rods, anti-slip sleeves are fixedly arranged.

[0028] On the surface of the clamping plate 23, a cylinder is fixedly installed. The cylinder is exposed through the 1-shaped sliding groove opened on the surface of the limiting box 17. After the clamping plate 23 is completely retracted into the limiting box 17, at this time, the upper end of the clamping plate 23 abuts against the lower end of the first toothed plate 20. If it is necessary to make the clamping plate 23 extend out of the limiting box 17 again, first pull the cylinder along the sliding groove, and then pull the first toothed plate 20 outwards. The first toothed plate 20 drives the gear roller 21 to rotate. The gear roller 21 drives the second toothed plate 22 to slide, so that the lower end of the second toothed plate 22 abuts against the upper end of the clamping plate 23. At this time, the clamping plate 23 extends out of the limiting box 17 and can maintain this state.

[0029] In the present utility model, when in use, first place the hub on the upper surface of the rotating table 2, that is, between the plurality of rotating rods 7. Subsequently, rotate the first threaded rod 10. The rotation of the first threaded rod 10 will drive the main gear 8 to rotate. The rotation of the main gear 8 will drive the three secondary gears 9 meshed with it to rotate. Each secondary gear 9 drives its corresponding rotating rod 7 to rotate. At the same time, utilize the self-locking principle between the first threaded rod 10 and the main gear 8 to clamp the hub. (Refer to the attached Figure 1 ) On one side of the frame 1, an arc-shaped plate integrated with the frame 1 is provided. On the surface of the arc-shaped plate, a plurality of angle scale lines 6 are provided. (Refer to the attached Figure 3 ) The pointer 4 has two sides, an inclined side and a vertical side. The vertical side points to the angle scale line 6 along the radial direction of the semi-circular protrusion. The vertical side is perpendicular to the upper surface of the rotating table 2. Therefore, the inclination angle of the rotating table 2 can be accurately read with the vertical side.

[0030] When the turntable 2 needs to be tilted, the second threaded rod 11 can be rotated. The rotation of the second threaded rod 11 drives the first gear 3 to rotate. Since the first gear 3 is fixedly mounted on the surface of the rotating shaft of the turntable 2, the turntable 2 and the first gear 3 rotate synchronously at the same time. The value can be read through the pointer 4 fixed to the other end of the rotating shaft and the angle scale line 6. Before operating the turntable 2, (refer to the attached Figure 3 ) First adjust the position of the limit box 17 so that the left edge of the collision plate 19, the specified angle scale line 6, and the outer edge of the arc plate coincide at one point.

[0031] When the vertical side of the pointer 4 coincides with the specified angle scale line 6, the collision column 5 at the top of the pointer 4 has come into contact with the collision plate 19, and the first tooth plate 20 fixedly connected to the collision plate 19 is completely inserted into the interior of the limit box 17. During the process of the first tooth plate 20 fully penetrating inward, the gear roller 21 is driven to rotate, and the rotation of the gear roller 21 drives the second tooth plate 22 to move left. The card plate 23 is retracted into the interior of the limit box 17 under the action of the spring 24, and supports the lower end of the first tooth plate 20, thereby releasing the position restriction of the limit box 17. After that, the limit box 17 moves away from the pointer 4 under the pulling force of the elastic rope 18, and the radius length of the collision column 5 is equal to the full extension distance of the collision plate 19 (that is, when the trigger card 23 is retracted back to the limit box 17, the first tooth plate 20 needs to move distance). At this time, the wheel hub has been adjusted to the required angle and subsequent grinding can be carried out. Through the cooperation of the pointer 4 and the angle scale line 6 and the movement of the limit box 17, the precise angle inclination and prompt of the rotating table 2 are achieved, making the position of the wheel hub more convenient for workers to grind, saving workers' physical exertion and improving workers' processing efficiency.

[0032] In the present invention, unless otherwise clearly specified or limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
