Flexible welding jig device for automotive body

Abstract

The invention relates to a flexible welding jig device for an automotive body. The welding jig device is characterized in that a guide shaft is fixed on a seat of an X-directional adjustable seat component and a locating pin hole is opened on the seat; a slide seat of a Y-directional adjustable slide seat component is sleeved on the guide shaft of the X-directional adjustable seat component and connected with the seat through a lock bolt; a supporting seat of a Z-directional adjustable supporting seat component is sleeved on the guide shaft of the Y-directional adjustable slide seat component and connected with the slide seat through a lock bolt; a graduation fluted disc is arranged in a swing locating mechanism of a swing mounting seat component and meshed with a graduation locating block arranged in the supporting seat, resetting and locking are achieved through a spring and a screw, and a slide shaft is arranged in a clamping slide bushing in the Z-directional adjustable supporting seat component and connected through a locking screw on the side; a rectangular hole system with an interval of 100mm is arranged on a hole system seat board, and a flexible and adjustable support is connected with the seat board in a locating mode through the hole system. The flexible welding jig device has the advantages of being reliable in structural design, convenient to weld, operate and adjust, high in adaptability, and capable of greatly shortening the design and production period of the welding jig of the automotive body and effectively reducing equipment cost for welding technique of the automotive body.

Description

technical field [0001] The invention relates to a flexible welding fixture device for an automobile body, which is applied in the field of welding process equipment. Background technique [0002] Welding fixture is the process equipment for positioning and clamping the weldment for welding, usually composed of base, support, positioning block, clamp and so on. The base is the basic unit of the welding fixture, generally composed of the base plate and section steel: the support is the supporting installation unit of the welding fixture, and positioning blocks, clamps and other components are installed on it to support and position. At present, welding fixtures generally adopt the method of designing a set of special fixtures for one welding station. When the workpiece changes, it is necessary to redesign and manufacture a new set of special welding fixtures, which leads to an increase in the manufacturing cost of welding fixtures and a decrease in efficiency. decline.
