Rough machining device for machining high-precision bearing roller for rail transit

Abstract

The invention discloses a rough machining device for machining a high-precision bearing roller for rail transit. The rough machining device comprises a mounting frame; a lifting platform is fixedly connected to the bottom wall inside the mounting frame, the upper surface of the lifting platform is fixedly connected to a first filter screen, and the upper surface of the lifting platform is fixedlyconnected to a positioning plate; and the upper surface of the lifting platform is fixedly connected to a threaded plate, a threaded rod is arranged on the outer surface of the threaded plate in a penetrating mode, the threaded plate is in threaded connection with the threaded rod, and a rubber pad is fixedly connected to the left end of the threaded rod. According to the rough machining device, amotor is arranged to drive a rotating shaft to rotate, the rotating shaft drives a second transmission rod to rotate, and the second transmission rod applies force to a rack discontinuously through ahalf-scale disc; and a reset spring is arranged to enable a cleaning device to move in a reciprocating mode, the material residues attached to the first filter screen are swept, so that the problem that the material residues are easily attached to the filter screen after the cutting fluid is mixed is solved, and therefore the purpose of conveniently collecting waste materials is achieved.

Description

technical field [0001] The invention relates to the technical field of processing high-precision bearing rollers, in particular to a roughing device for processing high-precision bearing rollers used in rail transit. Background technique [0002] Rail transit refers to a type of vehicle or transportation system that operating vehicles need to run on a specific track. The most typical rail transit is a railway system composed of traditional trains and standard railways. It is not only used in long-distance land transportation, but also Widely used in cities with short and medium distances. With the diversified development of train and railway technology, rail transit presents more and more public transportation. Bearings are an important part of rail transit. Its main function is Support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. [0003] With the increasing use of bearings in rail transit, the demand ...

Problems solved by technology

[0003] With the increasing use of bearings in rail transit, the demand for the output of bearing rollers is increasing, and the processing requirements for bearing rollers are also increasing. However, the existing high-precision bearings for rail transit The rough machining device for roller machining often uses cutting fluid to assist in the work process. After the cutting fluid mixes with material residue, it will adhere to the device, which affects the collection and treatment of residue, which in turn causes serious consequences of reducing the quality of work and prolonging the processing time. , so a rough machining device for high-precision bearing roller machining for rail transit is proposed to solve the above problems
