Description
Technical Field
The utility model relates to an assembly fixture, specifically speaking relates to a cylindrical roller bearing rivet assembly fixture, mainly is applied to bearing assembly process.
Background
When assembling the cylindrical roller bearing with the rivet, the rivet is often deviated in the riveting process, and the efficiency is low. The annular guide mould that adopts the later stage to close the cover because a guide mould can only correspond a model bearing, is different with the bearing size to rivet quantity difference, needs to formulate multiple mould, extravagant cost.
Disclosure of Invention
For solving above-mentioned problem, improve product quality, improve production efficiency, reduce cost, the utility model provides a cylindrical roller bearing assembly rivet frock.
The technical solution of the utility model is that: the utility model provides a cylindrical roller bearing assembly rivet frock which characterized in that: the method comprises the following steps: lifting platform, connecting rod, stand, 1# locating piece, 3# locating piece, 2# locating piece, 4#
The positioning block, the angular bisect positioning block and the circular ring are arranged; the lower part of the lifting platform is provided with a hydraulic cylinder, the upright post is arranged in the center of the platform, the upper half part of the upright post is provided with threads and is connected with the No. 3 positioning block (5) and the No. 4 positioning block (4 #)
The threads in the central holes of the positioning blocks (7) correspond to each other, the central holes of the positioning blocks No. 1 and No. 2 are not provided with threads and are respectively connected with the upper end and the lower end of the connecting rod, and the bottom end of the connecting rod is provided with a circular ring.
Compared with the prior art, the utility model have following advantage:
1. the processing of all cylindrical roller bearings needing rivets can be realized by one tool, and the cost is saved.
2. The working time is shortened, and the working efficiency is improved.
3. The occurrence of the rivet deflection phenomenon is avoided, and the product quality is improved.

Detailed Description
The embodiments are described below with reference to the accompanying drawings:
the utility model discloses a: the lifting platform comprises a lifting platform 1, a connecting rod 2, an upright column 3, a No. 1 positioning block 4, a No. 3 positioning block 5, a No. 2 positioning block 6, a No. 4 positioning block 7, an angular bisection positioning block 8 and a circular ring 9; the lower part of the lifting platform 1 is provided with a hydraulic cylinder, the upright post 3 is arranged in the center of the platform 1, the upper half part of the upright post is provided with a thread and is matched with No. 3
The threads in the central holes of the positioning blocks 5 and 4# 7 are corresponding, the central holes of the positioning blocks 1# 4 and 2# 6 are not provided with threads and are respectively connected with the upper end and the lower end of the connecting rod 2, and the bottom end of the connecting rod 2 is provided with a circular ring 9.
The utility model discloses the preparation adds man-hour to the bearing, equally divides the locating piece 8 with the angle and puts stand 3, parts connecting rod 2 on average. Put platform 1 with the holder that fills with the roller on, rotate 4# locating piece 7, 4# locating piece 7 can drive 2# locating piece 6, rises jointly, and simultaneously 2 power of using of bottom connecting rod are upwards, can exert oneself to both ends after 2 atress of upper end connecting rod, and connecting rod 2 can open jointly, and 2 sizes of opening of connecting rod are the same with holder rivet circumference size. And moving the lifting platform to connect the bearing with the tool. And (3) chiseling the rivet head into a cross shape by using a cross chisel to achieve interference fit with the retainer.
The utility model discloses, through using the proof, reach the assembly needs standard, satisfy the production needs.
