Abstract

The invention discloses an NL-3A pretreatment machine cover and rear cover jig. The NL-3A pretreatment machine cover and rear cover jig comprises a working platform, wherein the upper surface of the working platform is fixedly connected with a first lower fixed block, second lower fixed blocks and a step column, and the upper surface of the first lower fixed block and the upper surfaces of the second lower fixed blocks are provided with clamping grooves adapted with sleeves and hook-shaped supporting rods respectively; the front face of the first lower fixed block is fixedly connected with a limiting block; and the upper surface of the working platform is fixedly connected with a first quick clamp, a second quick clamp and a third quick clamp through bolts. By arranging the limiting block,a first quick clamp, the second quick clamp and the third quick clamp, the first quick clamp, the second quick clamp and the third quick clamp can rotate conveniently to drive a first upper fixed block, second upper fixed blocks and a lap joint plate to fix the sleeves and the hook-shaped supporting rods in the NL-3A pretreatment machine cover and rear cover jig, and thus the produced and manufactured product better meets the drawing requirements.

Description

technical field [0001] The invention relates to the technical field of fixtures for auto parts, in particular to a fixture for an NL-3A pre-processing machine cover and a rear cover. Background technique [0002] One end of the NL-3A pre-processing machine cover and the rear cover fixture are welded by a sleeve and two inclined hook-shaped support rods, as shown in the attached drawing of the manual image 3 As shown, it can provide support for the opening of the front and rear covers of the car. [0003] The existing NL-3A pre-processing machine cover and rear cover fixtures are produced by manual tailor welding, and the manual tailor welding operation method will cause the size and flatness to fail to meet the drawing requirements. Contents of the invention [0004] The purpose of the present invention is to solve the shortcoming existing in the prior art, and propose a kind of NL-3A front processing machine cover and back cover jig. [0005] In order to achieve the abo...
