Detailed Description
The invention will be further described with reference to the accompanying drawings, but the scope of the invention is not limited to the following description.
As shown in fig. 1, the cylindrical pin assembling tool comprises a compression screw 1, a pushing mechanism and a U-shaped frame 8, wherein one end of the U-shaped frame 8 is provided with a threaded hole, the other end of the U-shaped frame is provided with a through hole, the bottom of the through hole is provided with threads, the through hole is coaxial with the threaded hole, the compression screw 1 penetrates through one end of the threaded hole of the U-shaped frame 8, the compression screw 1 is internally provided with the through hole, and the pushing mechanism is fixedly installed in the compression screw 1.
The compression screw 1 can be divided into a boss which is convenient for an operator to twist and a cylinder structure which runs through one side of a threaded hole of the U-shaped frame 8, a through hole is formed in the whole compression screw 1, an outer threaded hole is formed in one end of the cylinder, and the tool is screwed into the U-shaped frame 8 through threads when in use.
The pushing mechanism mainly comprises a bearing installation sleeve 2, a bearing 3, a pressure head 4 and a thimble 10, wherein the upper end of the bearing installation sleeve 2 is a cylinder, and the cylinder extends into the bottom of the compression screw rod 1 and is connected through interference fit. For convenient installation bearing 3 and pressure head 4 of 2 lower extremes of bearing installation cover, the lower extreme is opened has the mounting groove that is used for installation bearing 3 and pressure head 4, and the mounting groove width is wider than the upper end cylinder.
In order to realize the matching of the upper end and the bearing 3 and the matching of the lower end and a cylindrical pin to be installed, the pressure head 4 is also divided into two sections, the upper end is of a cylindrical structure, the diameter of the lower end cylinder is larger than that of the upper end, therefore, a step structure is formed at the joint of the two cylinders, the step just abuts against the inner ring of the bearing 3, and a mounting hole for mounting the thimble 10 is formed in the lower end cylinder.
