Abstract

A fixing device for repairing an aluminum alloy wheel hub includes a base and universal wheels connected with the bottom of the base through support legs, wherein one side of the bottom plate is connected with air cylinders; the top of the bottom plate is connected with a fixing plate through a rotating shaft mounted rotationally; corresponding sides of vertical plates at the two sides of the fixing plate are each connected with a pressing plate through two sets of springs; adjusting bolts penetrate through the middles of the vertical plates; a first groove is formed in the middle of the fixing plate; two sets of guide rollers are rotationally mounted in the first groove; a top plate is fixedly mounted at the top of the bracket; a push plate is connected with the bottom of the top plate through a second hydraulic cylinder.

First claim

The invention claimed is:

1. A fixing device for repairing an aluminum alloy wheel hub, comprising a base and universal wheels connected with the bottom of the base through support legs, wherein the two sides of the top of the base are connected with a support plate through first hydraulic cylinders; a bottom plate is slidably mounted on the support plate through a sliding block; one side of the bottom plate is connected with air cylinders; the top of the bottom plate is connected with a fixing plate through a rotating shaft mounted rotationally; corresponding sides of vertical plates at the two sides of the fixing plate are each connected with a pressing plate through two sets of springs; adjusting bolts penetrate through the middles of the vertical plates; a first groove is formed in the middle of the fixing plate; two sets of guide rollers are rotationally mounted in the first groove; one set of the guide rollers are in drive connection with a motor mounted on one side of the bottom of the fixing plate through a belt; baffles are provided on the fixing plate at the tops of the guide rollers; a bracket is rotationally mounted at the position, located on one side of the fixing plate, above the support plate; a top plate is fixedly mounted at the top of the bracket; a push plate is connected with the bottom of the top plate through a second hydraulic cylinder; the center point of the push plate coincides with the center point of the fixing plate; and the push plate is provided with a positioning hole.

2. The fixing device for repairing the aluminum alloy wheel hub according to claim 1 , wherein the position, corresponding to the sliding position of the sliding block, of the support plate is provided with a matched sliding rail, and the sliding block is slidably mounted in the sliding rail.

3. The fixing device for repairing the aluminum alloy wheel hub according to claim 1 , wherein the vertical plates are welded on the fixing plate, the bottoms of the pressing plates do not make contact with the fixing plate, and the parts, located on the other sides of the springs, of the pressing plates are covered with rubber pads.

4. The fixing device for repairing the aluminum alloy wheel hub according to claim 1 , wherein the position, corresponding to the mounting position of the motor, of the fixing plate is provided with a matched second groove.

5. The fixing device for repairing the aluminum alloy wheel hub according to claim 1 , wherein the interval between the bottoms of the baffles and the guide rollers is not less than 5 mm, and collecting grooves are formed in the middles of the baffles.

6. The fixing device for repairing the aluminum alloy wheel hub according to claim 1 , wherein the edges, corresponding to the mounting positions of the baffles, of the first groove in the fixing plate are provided with flanges.

7. The fixing device for repairing the aluminum alloy wheel hub according to claim 1 , wherein the bottom of the bracket is rotationally connected to the fixing plate through a guide sleeve.

8. The fixing device for repairing the aluminum alloy wheel hub according to claim 1 , wherein the vertical plates and the pressing plates are in the same size, the longitudinal lengths of the vertical plates and the pressing plates are less than the longitudinal length of the fixing plate.

9. The fixing device for repairing the aluminum alloy wheel hub according to claim 1 , wherein the top of the bracket is not less than 1 m higher than the top of the fixing plate.
