Problems solved by technology

As far as we know, there is no special back pressure machine with back pressure grooves on the wheel hub to carry out the back pressure work of the wheel set. The existing back pressure work is all done by the unloading machine. Although this type of model has complete functions and a high degree of automation, the whole machine is complicated and expensive

Abstract

A wheel set back pressing machine comprises a machine frame, an oil cylinder device, a clamping jaw device and a hand pin. The machine frame is provided with a concave head, two vertical edges of the concave head are connected with two parallel vertical plates, a supporting plate is arranged between the two vertical plates, an inserting groove matched with the clamping jaw device is formed in the concave head, and hand pin holes are formed in the two vertical edges of the concave head. The oil cylinder device is arranged in a supporting plate in the rack, the clamping jaw device is composed of an upper half part and a lower half part, the lower half part is fixed to the bottom of the concave head of the machine frame, the upper half part is a movable part, protruding edges are arranged on the two sides of the upper half part and matched with the inserting grooves in the concave head, hand pin holes are further formed in the two sides of the upper half part, and protruding strips matched with the back pressure grooves are arranged in an inner opening of the clamping jaw device. The beneficial effects are that the structure is simple, and the whole machine only has several parts; the function is unique, only back pressing work is carried out, and withdrawal is not carried out; and cost is saved, economy and practicability are achieved, parts are few, and production, assembly and maintenance are easy.

Description

technical field [0001] The invention relates to a rail transit equipment machine, in particular to a wheel set reverse press machine. It is suitable for the back pressure work of the wheel set with the back pressure groove on the hub (such as all the wheelsets of the HXD1 series). Background technique [0002] For the safety of rail transportation, after the wheel set is press-fitted, in order to test the press-fit technology, a back-pressure test must be carried out. As far as we know, there is no special back pressure machine with back pressure groove on the wheel hub to carry out the back pressure work of the wheel set. The existing back pressure work is all done by the unloading machine. Although this model has complete functions and a high degree of automation, the whole machine is complicated and expensive. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the invention provides a wheel set counter-pressing machine, which has a...
