Car body assembly welding clamp

Abstract

The invention discloses a car body assembly welding clamp. The car body assembly welding clamp comprises a base and two side body clamping components arranged on the base mutually symmetrically. Each side body clamping component comprises an installing seat, a guide seat, a hinge seat and a clamping support, wherein a lead screw is arranged in the installing seat; sliding rods are arranged on two sides of the lead screw; the extending direction of the sliding rods and the lead screw is kept consistent with the length direction of the installing seat; the sliding rods are sleeved with the guide seat; the lead screw is in threaded connection with the bottom of the guide seat; one end of the lead screw is connected with a driving motor which is used for driving the guide seat to slide along the sliding rods; the hinge seat is installed on the guide seat; the clamping support is hinged to the hinge seat; the guide seat is further provided with an air cylinder; and a piston rod of the air cylinder is connected with the clamping support to drive the clamping support to rotate around a hinge point of the hinge seat. The assembly difficulty is lowered for operators, the operation safety and production takt are improved, and the production efficiency is effectively improved.

Description

technical field [0001] The invention relates to the field of automobile manufacturing, in particular to an automobile body assembly welding jig. Background technique [0002] In the vehicle assembly and welding production line, the most important link is the welding of the body assembly. In the prior art, the welding of the body assembly is realized through welding fixtures. The welding fixtures include left and right side clamping brackets, left and right sides The clamping bracket is set vertically. When the body assembly is used to install the left and right sides of the body before welding, due to the heavy weight of the left and right sides, it is difficult for the operator to install the parts, and the safety of personnel is low. It is difficult to guarantee the production takt. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a welding jig for automobile body assembly, which reduces...
