Drilling and positioning device for swinging part of four-claw material cover

Abstract

The invention provides a drilling positioning device of a four-claw material cover swing piece, and belongs to machining tools of bulk cement truck parts. The drilling positioning device of the four-claw material cover swing piece is characterized in that the drilling positioning device is mainly composed of a drilling seat plate, lower positioning pins, a pressing plate positioning pin, pressing plates, pressing nuts and upper positioning pins; the lower portion of the drilling seat plate is provided with an inverted T-shaped plate, a vertical face plate is arranged on the upper portion of the drilling seat plate, a main pin hole is formed in the center position of the vertical face plate, the pressing plate positioning pin is mounted at the center position of the vertical face plate, the front section and the rear section of the pressing plate positioning pin are respectively provided with one pressing plate in a sleeved mode, the front end and the rear end of the pressing plate positioning pin are respectively provided with an external thread and are respectively provided with one pressing nut in a screwing mode, a left lower pin hole I and a right lower pin hole I are formed in the lower portion of the vertical face plate, the upper end of the vertical face plate is provided with a left upper pin hole I and a right upper pin hole I respectively, and the left upper pin hole I and the right upper pin hole I are respectively provided with one upper positioning pin. In the using process, the front side face and the rear side face of the vertical face plate of the drilling seat plate are respectively provided with a left swing piece and a right swing piece, bolt holes are formed in the vertical direction of the machined swing pieces, positioning is accurate, and the production efficiency is high.

Description

technical field [0001] The invention belongs to processing tools for parts of bulk cement vehicles, in particular to a processing and positioning device for a swinging part of a material cover of a bulk cement vehicle. Background technique [0002] The material cover of the bulk cement truck is usually a three-claw material cover, but the movement mechanism of the three-claw material cover is installed on the tank body of the bulk cement vehicle, which often causes the height of the bulk cement vehicle to exceed the standard, and the movement mechanism of the three-claw material cover is more complicated , the manufacturing cost is relatively high, see: Chinese Patent, Name: Bulk Cement Tank Single Arm Center Spinning Cover, Patent No.: 201020637889.1, Publication No.: CN201923540U; In order to meet market requirements, a new type of four Claw material cover, the swinging part on the four-claw material cover, due to the large demand, can only be assembled from outsourced fin...
