Abstract

A welding fixture for formula racing comprises a flexible base, a horizontal adjustment bolt, a main positioning clamping unit, an auxiliary positioning unit, a stand column mechanism, a top positioning beam, a lateral positioning clamping unit and an upper positioning clamping unit. The horizontal adjustment bolt, the main positioning clamping unit and the auxiliary positioning unit are fixedly arranged on the flexible base; the stand column mechanism has limiting and safety functions; the top positioning beam is connected with the stand column mechanism; the lateral positioning clamping unit is fixedly arranged on the stand column mechanism; the upper positioning clamping unit is fixedly arranged on the top positioning beam; the main positioning clamping unit, the auxiliary positioning unit, the lateral positioning clamping unit and the upper positioning clamping unit can move on the flexible base, the stand column mechanism and the top positioning beam; and the stand column mechanism comprises a stand column, a stand column fixing seat, a limiting block, a limiting switch and a limiting spring. According to the welding fixture for the formula racing, correct relative positions of parts can be guaranteed when assembling positioned welding and welding deformation of workpieces can be prevented or reduced.

Description

technical field [0001] The invention relates to a welding jig for a formula racing car. Background technique [0002] The formula racing car that the present invention relates to is a student formula racing car, and its body is a frame structure, and the frame is 25mm by outer diameter, and the pipe material that wall thickness is 2.5mm and total length is 20mm, and the wall thickness is 2.5mm square steel to form. The floor is designed with a structure similar to a three-dimensional box structure, and is designed using a balance calculation of stiffness and weight. The strength design sequence of each part of the car body is the same as the usual strength design. First, the surface load, the load variation (frequency) during braking and driving must be grasped, and then the stress variation of the parts is predicted using finite element analysis. Predict life with reference to the fatigue strength properties of the material and evaluate the results. When designing a Formu...
