An automobile body welding jig

Abstract

The invention discloses an automobile body welding fixture. The automobile body welding fixture comprises a telescopic module; the telescopic module comprises a base, and the middle of the top end ofthe base is fixedly connected with the bottom end of a shell; the two sides of an upper fixture are symmetrically provided with two buffer blocks, and the buffer blocks are fixedly connected with theupper fixture through fixed plates; one side of the top end of the shell is provided with a lower fixture right facing the upper fixture; a buffer plate is arranged at the top end of the lower fixture; and a pressure transmitter is arranged at the top end of a buffer cylinder. According to the automobile body welding fixture, an automobile body can be clamped through the upper fixture and the lower fixture, a piston rod can be extruded through extrusion force, when the piston rod is extruded, the pressure of air in the buffer cylinder is increased, the situation that impressions are generatedon the automobile body due to the clamping force between the upper fixture and the lower fixture can be avoided through the high-pressure air, and the automobile body can be further protected throughthe buffer blocks and can be clamped all the time by the clamping force between the upper fixture and the lower fixture through the pressure transmitter without moving.

Description

Technical field [0001] The invention relates to an automobile body fixture, in particular to an automobile body welding fixture. Background technique [0002] In the assembly and welding production process of automobile bodies, in order to ensure product quality, improve labor productivity and reduce labor intensity, some tools and devices used to clamp and determine the position of the workpiece are often used to complete assembly and welding. We collectively refer to these tools and devices as welding fixtures. The fixed weldment is placed on this type of fixture to complete the welding of all welds. Its main task is to prevent welding deformation and adjust the welds in various positions as far as possible to the most favorable position for welding. [0003] In the common car body welding process, when the fixture contacts the car body, it will squeeze the car body, causing dents on the car body surface, affecting the quality of the car body, and easy to rework and rework, imp...
