Butt-joint punching device for large cabin body and chassis

Abstract

The invention discloses a butt-joint punching device for a large cabin body and a chassis. The butt-joint punching device comprises an electric hand drill (309), and further comprises a rack assembly(1), a mounting plate (2) arranged on the rack assembly (1) and a support assembly fixed on the mounting plate (2), the support assembly comprises a supporting plate with one side fixedly provided with the electric hand drill (309), a guide rail and sliding block assembly (302), a bent plate (308) with a through hole in the middle and a mandrel (306) penetrating through the through hole, the guiderail and sliding block assembly (302) comprises the guide rail connected with the bent plate (308) and a sliding block connected with the supporting plate, and is used for enabling the supporting plate and the electric hand drill to move up and down smoothly, a gear (304) is arranged at one end of the mandrel (306), a hand wheel assembly (307) is arranged at the other end of the mandrel (306), and a rack (303) matched with the gear (304) is arranged at the bottom of the supporting plate. According to the butt-joint punching device for the large cabin body and the chassis, punching can be realized at different positions, and the problem that an electric drill needs to be held by hands for punching is solved.

Description

technical field [0001] The invention belongs to the technical field of assembly technology, and more specifically relates to a docking and punching device for a large cabin body and a chassis. Background technique [0002] The large thermal insulation cabin is one of the important components of a certain type of product. The docking and assembly process of the cabin body and the chassis is an indispensable link in the production process, and it is also a time-consuming and labor-intensive link. [0003] The docking assembly process of the cabin and the chassis: the cabin is hoisted to the supporting beam on the chassis, and after adjusting and aligning to ensure the relative position requirements between the cabin and the chassis, the cabin must be aligned with the mounting holes on both sides of the supporting beam. Drill holes on the bottom of the body. [0004] There is no automatic punching device at present, and the prior art mainly punches holes manually. When punchi...

Problems solved by technology

[0004] At present, there is no automatic punching device. The existing technology mainly punches holes manually. When punching holes, the worker holds a hand electric drill, bends over or squats, and punches holes one by one from bottom to top.

This method is not only labor-intensive and inefficient; moreover, because the outer layer of the cabin is made of carbon fiber material, a large amount of dust will be generated when punching holes, which will easily fall on the face and mouth of the operator, and will also damage the influence on the human body
