Internal supporting tool system for large workpiece

Abstract

The invention discloses an internal supporting tool system for a large workpiece. The internal supporting tool system comprises a bottom supporting part and an upper supporting and positioning part which are arranged in a welding workpiece, wherein the bottom supporting part comprises a bottom supporting frame, a scissor fork lifting mechanism and a bottom electric push rod; and the upper supporting and positioning part comprises an upper supporting frame, a supporting plate and an upper electric push rod; the lower end of the scissor fork lifting mechanism is mounted on the bottom supporting frame, the upper end of the scissor fork lifting mechanism is mounted on the upper supporting frame, the scissor fork lifting mechanism drives the upper supporting frame to ascend and descend; one end of the bottom electric push rod is connected with the scissor fork lifting mechanism, and the other end of the bottom electric push rod is mounted on the bottom supporting frame; one end of the upper electric push rod is connected with the supporting plate arranged outside the upper supporting frame, and the other end of the upper electric push rod is mounted on the upper supporting frame; and the supporting plate corresponds to the position of a welding seam of the welding workpiece. The internal supporting tool system has the advantages that the supporting mode is changed into equipment operation from original manual operation, so that the automation degree is high, the supporting reliability is higher, the position accuracy can be guaranteed, and the welding efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of processing and assembly, in particular to an internal support tooling system for a large workpiece used in the internal welding of a large automobile body. Background technique [0002] In the processing and assembly process of large workpieces, welding is an important process. In the welding process, in order to prevent the deformation of each component and ensure the welding quality, it is usually necessary to use tooling fixtures to assist positioning to complete the welding work. The existing large automobile body In the process of welding, manual participation is still required. Workers need to enter the interior of the car body and use rods to support the inner wall of the car body to prevent deformation of the car body. However, in the automated production process, a lot of manual participation is required, which itself is a problem. It is a low-efficiency method, and because there is no fixed tool...

[0002] In the processing and assembly process of large workpieces, welding is an important process. In the welding process, in order to prevent the deformation of various parts and ensure the welding quality, it is usually necessary to use fixtures to assist positioning to complete the welding work. The existing large car body In the process of welding, manual participation is still required. Workers need to enter the interior of the car body and use rods to support the inner wall of the car body to prevent deformation of the car body. However, in the automated production process, a lot of manual participation is required, which itself is a problem. It is a low-efficiency method, and because there is no fixed tooling for support, welding deformation cannot be controlled, production capacity and quality cannot be improved, and customer requirements cannot be met
