Abstract

The invention discloses a rotary deep hole machining device, and belongs to the technical field of part machining processes. The purpose of deep hole machining which cannot be completed by a common drilling machine is achieved through a 180-degree coaxial rotary drilling jig. The device comprises a bottom plate, a base, a central shaft, an upper die plate, a lower die plate, a press plate, a fastening screw, a right-angled press plate, a location bolt, a guide plate, a slide location pin and a vertical column. After a track plate body is subjected to tri-directional location and clamped, the upper half section of a pin hole of the track plate body is drilled, the bottom plate is rotated by 180 degrees, the lower half section of the pin hole of the track plate body is drilled, and deep holemachining is realized in combination with the common drilling machine; and meanwhile, rapid clamping can be realized, high machining efficiency is achieved, and the accuracy requirement is met.

Description

technical field [0001] The invention belongs to the technical field of parts processing technology, relates to the processing technology of important parts of the action system of engineering vehicles, and relates to a device for processing deep holes such as through holes of track plate bodies. Background technique [0002] A new type of track shoe body, the size of which increases, and the depth of the pin hole becomes longer at the same time, and the ordinary drilling machine cannot meet the drilling depth requirement. The purchase of new equipment or cutting tools will lead to a rapid increase in processing costs and cause the original equipment to be idle. Develop and design a rotary deep hole processing device, installed on a common drilling machine, which can expand the capacity of existing equipment, process products that meet product precision requirements, and have high efficiency at the same time. In this paper, the design of the rotary deep hole processing devic...
