Further, the base is a rectangular body, the top surface of the base is an inclined plane, a bearing hole is formed in the center of the inclined plane of the base, positioning holes with the same number as the cylinder body holes are formed in the periphery of the inclined plane of the base, and an included angle between the inclined plane of the base and the bottom surface of the base is 5 degrees.
Further, the bearing is a tapered roller bearing.
Further, the chuck is a three-jaw chuck.
The invention has the beneficial effects that:
1. by adopting the technical scheme of the structure, the invention can be arranged on a working table of a press machine by using a positioning key, the inclined plane of the base and the bottom surface form an included angle of 5 degrees, so that a cylinder body hole is vertical to the working table, a workpiece is clamped by using a chuck, meanwhile, a flange is rotated under the action of a bearing, a bolt is inserted into a positioning bush of the base to complete indexing, the assembling and positioning precision can be effectively ensured, and the technical problems of low assembling qualification rate and extremely low efficiency in the installation process of the existing cylinder body copper sleeve are effectively solved.
2. After the invention is used, when the cylinder copper bush is installed, the cylinder plunger hole is vertical to the workbench, so that the assembly precision can be ensured, the phenomenon of trimming can not occur, and the assembly qualification rate is improved to 100 percent. Therefore, compared with the background art, the invention has the advantages of simple structure, convenient operation, easy assembly field use, capability of improving the assembly qualification rate and the like.
