Problems solved by technology

[0002] At present, the tracks in the heavy-duty crawler chassis of construction machinery are generally connected by casting track shoes. The accuracy of the pin holes of the track shoes is completely controlled by casting, so the accuracy of the pin holes is usually low, resulting in uneven meshing when the track is walking. , abnormal noise, and cracking of track pins due to uneven force
Therefore, in order to improve the linking accuracy of the track shoe, it is necessary to finish the track shoe pin hole, for example, to optimize the parallelism, coaxiality and cylindricity of the track shoe pin hole. The pin holes on the track shoe are intermittent elongated holes. The existing machining methods are, for example, using lathe transformation or floor boring machine for processing. The processing efficiency is low, and the parallelism, coaxiality and cylindricity of the track shoe pin holes are not easy to obtain. Guaranteed, and the inner surface of the pin hole is rough, in other words, the existing form of using the general machine tool to process the pin hole of the track shoe is difficult to meet the requirements of convenience, high efficiency and economy for the finishing of the track shoe pin hole, the purpose of the present invention is to solve above question

Abstract

The invention discloses track shoe pin hole machining equipment. The track shoe pin hole machining equipment comprises a base, and a clamping mechanism, a machining mechanism and a feeding mechanism mounted on the base. The clamping mechanism is used for clamping track shoes and keeping the track shoes in the machining direction, the machining mechanism is used for machining pin holes, the feeding mechanism is used for enabling the clamping mechanism and the machining mechanism to move relatively after the track shoes are kept in the machining direction, and the machining mechanism machines the pin holes in the track shoes kept in the machining direction in the process of relative movement of the clamping mechanism and the machining mechanism. The track shoe pin hole machining equipment is specially used for machining the pin holes of the track shoes, the track shoes are kept in the machining direction through the clamping mechanism according to the unique structural design of the track shoes, then the pin holes of the track shoes kept in the machining direction are subjected to finish machining through the machining mechanism, and machining efficiency and effect can be improved effectively.
