Embodiment Construction

[0012] Such as figure 1 -2 shows an embodiment of the present invention, the linear guide rail 2 is arranged on the top of the base 1 . The press mounting platform 3 is arranged on the linear guide rail 2 and can move on the linear guide rail. The press-fitting platform 3 is provided with four symmetrical positioning blocks 4 in pairs and a supporting platform between the positioning blocks. The positioning block 4 realizes the positioning of the wheel to be press-fitted. As a guide structure for the support platform 5 to move up and down, the inner side of the positioning block 4 is also provided with a concave groove 7 perpendicular to the support platform 5, and the support platform 5 is provided with a convex groove 7 slidingly matched with the inner side of the positioning block 4. so that the support platform 5 can move up and down along the direction of the concave slot 7. Also have four rollers 8 that are arranged on the same level on the support platform 5 . The s...

Abstract

The invention discloses a press fitting tooling for a wheel connecting pin. The press fitting tooling comprises a base, a linear guiding track and a press fitting platform. The linear guiding track is installed on the base, the press fitting platform can move on the linear guiding track, and at least two locating blocks and supporting platforms are arranged on the press fitting platform; and the locating blocks are provided with guiding mechanisms for supporting the supporting platforms to move vertically, the supporting platforms are provided with rollers, and the supporting platforms are connected with a supporting platform lifting device. The press fitting tooling can achieve precise press fitting on the wheel connecting pin, can conduct press fitting of the connecting pin at different positions of the same wheel, is simple in structure and convenient to use, reduces labor intensity of operators, and improves connecting pin assembling quality and production efficiency.

Description

technical field [0001] The invention relates to a press-fitting device for a wheel of a railway locomotive, in particular to a press-fitting device for a connecting pin of a wheel of a railway locomotive. Background technique [0002] According to actual needs, a lot of railway rolling stock needs its wheel connecting pin to be press-fitted. The traditional assembly method of the connecting pin is to put it into liquid nitrogen to cool it, and then use a sledgehammer to knock it into the wheel pin hole by manpower. The assembly process has low production efficiency and high labor intensity. In addition, improper operation by the operator may easily cause damage to the wheel pin hole and fatigue impact defects at the root of the connecting pin. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a simple structure, practical and convenient, in order to meet the actual needs of precise press-fitting of the wheel conne...
