Rolling type bearing pressing tool

Abstract

The utility model discloses a rolling type bearing pressing tool. The rolling type bearing pressing tool comprises a lower die holder; the die is characterized in that a first core shaft is inserted into a top end opening of the lower die base, a second core shaft is arranged on the outer wall, close to the bottom end, of the first core shaft in a sleeved mode, copper sleeves are fixed to the outer walls of the left end and the right end of the second core shaft through check rings, and idler wheels are arranged on the outer walls of the circumferences of the copper sleeves in a sleeved mode. The outer wall of the top end of the first mandrel is sleeved with an upper die rod. The rolling type bearing compression tool is reasonable in structural design, compression operation on a bearing is achieved through mutual matching of the idler wheels and the lower die base, compression of the bearing is completed instead of a large-load tension and compression testing machine and a compression die, the bottleneck problems of the bearing compression technology and production resources are solved, and production cost is reduced.

Description

Technical Field

[0001] The utility model relates to a rolling bearing pressing tool. Background Art

[0002] Currently, bearings are subjected to pressure-reducing operations during the assembly process. Traditional bearing pressure reduction is mainly performed using pressure reduction dies and tension-compression testing machines. The specific operation process places high demands on operators and equipment, and the production cost is high. Utility Model Content

[0003] The utility model overcomes the shortcomings of the prior art and provides a rolling bearing pressing tool.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is: a rolling bearing pressing tool, comprising:

[0005] Lower die base;

[0006] The feature is that a first core shaft is inserted into the top port of the lower die base, a second core shaft is sleeved on the outer wall of the first core shaft near the bottom end, copper sleeves are fixed on the outer walls of the left and right ends of the second core shaft through retaining rings, a roller is sleeved on the circumferential outer wall of the copper sleeve, and an upper die rod is sleeved on the outer wall of the top end of the first core shaft.

[0007] In the above structure, the second core shaft is connected to the first core shaft via a pin.

[0008] In the above structure, the connection between the upper mold rod and the first core shaft is fixed by a top screw.

[0009] Compared with the existing technology, the beneficial effects of the present invention are: the rolling bearing pressing tooling structure of the present invention is reasonably designed, and the pressing operation of the bearing is realized through the mutual cooperation of the roller and the lower die seat, replacing the large-load tension and compression testing machine and the pressing die to complete the pressing of the bearing, solving the bottleneck problems of bearing pressing technology and production resources, and reducing production costs.

[0014] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0015] like Figs. 1-2 As shown, a rolling bearing pressing tool comprises:

[0016] Lower die base 1;

[0017] It is characterized in that: a first core shaft 2 is inserted into the top port of the lower die base 1, a second core shaft 3 is sleeved on the outer wall of the first core shaft 2 near the bottom end, copper sleeves 5 are fixed on the outer walls of the left and right ends of the second core shaft 3 through retaining rings 4, a roller 6 is sleeved on the circumferential outer wall of the copper sleeve 5, and an upper die rod 7 is sleeved on the outer wall of the top end of the first core shaft 2.

[0018] In the above structure, the second core shaft 3 and the first core shaft 2 are connected via a pin shaft 8 .

[0019] In the above structure, the connection between the upper mold rod 7 and the first core shaft 2 is fixed by a top screw 9.

[0020] To operate the roller-type bearing compression tooling of this utility model, the upper die rod is connected to the radial drill. The bearing 11, with the bearing seat 10 fixed, is placed under the first mandrel. The bottom end of the first mandrel is inserted into the lower die seat, which contacts the radial drill table. The radial drill is started and the roller is driven to rotate, thereby compressing the bearing.

[0021] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
