Summary of the Utility Model

[0005] The purpose of the utility model is to provide a clamping tooling for automobile bushing grinding.

[0006] The technical problem solved by the utility model is that the existing equipment is only convenient for grinding the outer ring of the automobile bushing and is not convenient for grinding the inner ring of the automobile bushing while grinding the outer ring of the automobile bushing.

[0007] The utility model can be realized by the following technical solutions: an automobile bushing grinding and clamping tooling, which comprises a grinding table. A plurality of fixing grooves are evenly formed in the top wall of the grinding table. An automobile bushing clamping mechanism is arranged in the inner cavity of the fixing groove. An automobile bushing grinding mechanism is arranged above the grinding table. The automobile bushing grinding mechanism comprises a lifting frame floatingly connected above the grinding table. An outer ring grinding ring corresponding to each fixing groove is rotatably connected in the inner cavity of the lifting frame. An inner ring grinding ring is fixedly installed in the inner cavity of the outer ring grinding ring. A driving gear is fixedly installed at the center of the inner cavity of the lifting frame. A driven gear meshing with the driving gear is fixedly sleeved on the outer peripheral wall of the outer ring grinding ring. Rotating the driving gear causes the plurality of driven gears to rotate synchronously through meshing.

[0008] A further technical improvement of the utility model lies in that: the plurality of fixing grooves are distributed in a circular array on the top wall of the grinding table.

[0009] A further technical improvement of the utility model lies in that: the automobile bushing clamping mechanism comprises an inner cylinder fixed at the center of the inner cavity of the fixing groove, and the inner cylinder is used for guiding the automobile bushing to be ground; two arc-shaped clamping plates are symmetrically and slidably connected in the inner cavity of the fixing groove and on both sides of the inner cylinder.

The setting of the anti-slip layers facilitates further improving the clamping stability of the automobile bushing.

[0010] A further technical improvement of the utility model lies in that: a driving component for enabling the two arc-shaped clamping plates to move relatively is arranged in the inner cavity of the grinding table. The driving component comprises two rotating connecting plates symmetrically and rotatably connected in the inner cavity of the grinding table.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. After fixing multiple automotive bushings, the present utility model synchronously moves the outer grinding ring and the inner grinding ring downward by lowering the lifting frame. When the outer grinding ring and the inner grinding ring just cover the inner and outer rings of the automotive bushing to be ground, the driving gear is rotated. Since the driving gear meshes with the driven gear fixedly sleeved on the outer peripheral wall of the outer grinding ring, the meshing action can drive multiple outer grinding rings to rotate simultaneously. Since the outer grinding ring is fixedly connected to the inner grinding ring, the rotation of the outer grinding ring can drive the inner grinding ring to rotate synchronously. Grinding the inner and outer rings of the automotive bushing simultaneously facilitates improving the overall grinding efficiency of the equipment, and thus facilitates meeting the usage requirements of the staff.

[0015] 2. The present utility model places multiple automotive bushings to be ground in multiple fixing grooves of the grinding table. When placing, the inner ring of the automotive bushing wraps the inner cylinder in the fixing groove. After placement, two electric telescopic rods are driven simultaneously. The synchronous movement of the annular plate is achieved by the elongation of the electric telescopic rods. The movement of the annular plate drives multiple T-shaped plates to slide downward. When the T-shaped plates slide downward, two sliding blocks slide towards each other by rotating the connecting plate. The synchronous movement of two arc-shaped clamping plates is achieved by the opposite sliding of the two sliding blocks. Fixing multiple automotive bushings simultaneously by the movement of the two arc-shaped clamping plates, and fixing the automotive bushing before grinding it can prevent the automotive bushing from rotating during the grinding process, which affects the subsequent grinding effect of the equipment.

Two arc-shaped clamping plates 14 for clamping the outer ring of the automotive bushing are symmetrically and slidably connected on the partition plate 12 and on both sides of the inner cylinder 13.

[0027] A driving mechanism for making the two arc-shaped clamping plates 14 move relative to each other is arranged in the inner cavity of the grinding table 1. The driving mechanism includes an inner groove 15 opened in the inner cavity of the grinding table 1. A fixing plate 16 is fixedly installed between the two inner side walls of the inner groove 15. Two sliding blocks 17 are symmetrically and slidably connected to the fixing plate 16. The sliding blocks 17 are fixedly connected to the arc-shaped clamping plates 14. Two rotating connecting plates 18 are symmetrically and rotatably connected to the front surface of the fixing plate 16. A first convex column 19 is fixedly installed on the front surface of the sliding block 17. A first strip-shaped inclined hole 110 for the first convex column 19 to slide is penetrated and opened in the inner cavity of the rotating connecting plate 18. A T-shaped plate 111 with the same number as the fixing grooves 11 is penetrated and slidably connected to the bottom wall of the grinding table 1. The T-shaped plate 111 extends into the inner cavity of the inner groove 15. Two second convex columns 112 are symmetrically and fixedly installed on the front surface of the T-shaped plate 111 and in the inner cavity of the inner groove 15. A second strip-shaped inclined hole 113 for the second convex column 112 to slide is penetrated and opened in the inner cavity of the rotating connecting plate 18.

[0028] Two electric telescopic rods 3 are symmetrically and fixedly installed on both sides of the bottom wall of the grinding table 1. The output end of the electric telescopic rod 3 is fixedly installed with a ring plate 31. The ring plate 31 is fixedly connected to the T-shaped plate 111.

[0029] Above the grinding table 1, a grinding mechanism is provided. The grinding mechanism includes a lifting frame 21 floatingly connected above the grinding table 1. At the center of the inner cavity of the lifting frame 21, a driving gear 24 is rotatably connected. In the inner cavity of the lifting frame 21 and around the driving gear 24, outer grinding rings 22 corresponding to the fixing grooves 11 one by one are rotatably connected. Inside the outer grinding rings 22, inner grinding rings 23 are fixedly installed. On the outer peripheral wall of the outer grinding rings 22, driven gears 25 meshing with the driving gear 24 are fixedly sleeved.

[0030] A servo motor 26 for driving the driving gear 24 to rotate is fixedly installed on the lifting frame 21.

[0031] At the center of the inner cavity of the grinding table 1, a hydraulic telescopic rod 2 is fixedly installed.

[0033] After a plurality of automotive bushings are fixed, the hydraulic telescopic rod 2 is driven to move the lifting frame 21 downward. Through the downward movement of the lifting frame 21, the outer grinding rings 22 and the inner grinding rings 23 move downward synchronously. When the outer grinding rings 22 and the inner grinding rings 23 just cover the inner and outer rings of the automotive bushings to be ground, the servo motor 26 is driven. Through the servo motor 26, the driving gear 24 is driven to rotate. Since the driving gear 24 meshes with the driven gears 25 fixedly sleeved on the outer peripheral wall of the outer grinding rings 22, through the meshing action, a plurality of outer grinding rings 22 can be driven to rotate simultaneously. Since the outer grinding rings 22 are fixedly connected to the inner grinding rings 23, therefore, through the rotation of the outer grinding rings 22, the inner grinding rings 23 can be driven to rotate synchronously. By grinding the inner and outer rings of the automotive bushings simultaneously, it is convenient to improve the overall grinding efficiency of the equipment, and thus it is convenient to meet the usage requirements of the staff.
