Problems solved by technology

The disadvantages of this delivery method are: 1. It can only meet the production of a single model: due to the heavy weight of the existing positioning fixture (the mass reaches 2.5 tons), it is not easy to replace; 2. The existing positioning fixtures located on both sides of the floor line The clamping system occupies a large area and the mechanism is complicated: there are both a flipping mechanism after the fixture is connected to the piece, and a horizontal conveying mechanism for sending the piece; 3. The positioning accuracy is poor, and the positioning error is 1 to 2mm; 4. Due to the existing positioning and clamping The structure of the system itself is huge, which results in a large amount of civil construction for the positioning and clamping system, which increases the cost of equipment

Abstract

The invention discloses a rapid positioning and clamping system for a flexible vehicle body welding line gripper clamp assembly. The rapid positioning and clamping system for the flexible vehicle body welding line gripper clamp assembly comprises the gripper clamp assembly and at least four upright posts, wherein the gripper clamp assembly comprises a frame; a gripper clamp is arranged on the frame; the at least four upright posts are mounted on a welding line platform and are used for carrying the frame; a three-direction positioning mechanism and a two-direction positioning mechanism are respectively arranged on the at least two upright posts which are positioned on the same side of the central line of the welding line platform; one compressing mechanism used for compressing the corresponding three-direction positioning mechanism and the corresponding two-direction positioning mechanism is arranged on the side wall of each upright post positioned on the outer side of the welding line platform. The rapid positioning and clamping system is simple in working mode, high in positioning accuracy, and firm and reliable in positioning, and can meet the production of various vehicle types; meanwhile, the positioning accuracy in the X,Y and Z directions is ensured; the rapid positioning and compressing between a positioned body and a positioning body are realized.

Description

technical field [0001] The invention belongs to the technical field of body welding, and in particular relates to a positioning and clamping system used in a flexible body welding line. Background technique [0002] The assembly station equipment of passenger cars mainly consists of two parts: the floor conveying line for conveying the bottom plate of the car body, the upper and lower parts mechanism of the left and right side panels, and the welding robots for the left and right side panels. The working process is as follows: the car bottom plate is transported to the assembly station through the conveying line, and when it is in place, the conveying line receives a stop signal when the workpiece is in place, and the conveying line stops running; at the same time, the left and right side wall upper mechanism moves to send the left and right side walls to the car Both sides of the bottom plate; after the side wall is in place, the welding robots on both sides of the floor co...
