Positioning clamping device for auto parts processing

Abstract

The invention relates to the field of workpiece fixing and positioning, and discloses a positioning and clamping device for automobile part machining. The positioning and clamping device comprises a support, wherein the support comprises a guide rail, at least two clamping units and at least one supporting unit are arranged on the guide rail, each clamping unit comprises a clamping mechanism and two first sliding seats, each first sliding seat is hinged with a telescopic mechanism, the ends, far away from the sliding seats, of the telescopic mechanisms are both hinged to the clamping mechanism, the first sliding seats are slidably connected to the guide rail, and the first sliding seats are in threaded connection with first locking screws for locking the first sliding seats on the guide rail; and the supporting unit comprises a second sliding seat and a screw rod, the screw rod is in threaded connection with the second sliding seat, a spherical air bag is fixedly arranged at the end, facing the center of the guide rail, of the screw rod, the second sliding seat is slidably connected to the guide rail, and the second sliding seat is in threaded connection with a second locking screwfor locking the second sliding seat on the guide rail. According to the positioning and clamping device, accurately positioning and clamping of the parts with different specifications are realized.

Description

technical field [0001] The invention relates to the field of fixing and positioning of workpieces. Background technique [0002] The body and the cargo compartment of the pickup truck are combined and welded by many stamped sheet metal parts of different sizes to form an assembly, and then the welded assembly parts are combined and welded into the body and the cargo compartment of the pickup truck. Set of positioning and clamping devices. The positioning and clamping devices can combine sheet metal parts or welding sub-assemblies of different sizes for welding. The sheet metal parts or welding sub-assemblies have corresponding placement on the positioning and clamping device Position, each sheet metal part, component and sub-assembly must use hole positioning, column positioning and surface positioning, and must use clamping mechanisms such as cylinders or manual quick clamps to ensure that the quality of the welded assembly meets Require. [0003] The clamping mechanism f...

Problems solved by technology

[0004] There are two main problems in the above-mentioned prior art: one is that there are many clamping mechanisms installed in the existing positioning and clamping device, which takes up a large space, and the number of clamping mechanisms cannot be reduced under the premise of ensuring positioning accuracy and product precision quality , so it is difficult to achieve the improvement of welding efficiency and the reduction of labor intensity of employees; the second is that the existing positioning clamping device has poor versatility, and a set of positioning clamping device needs to be prepared separately for each specification of weldment, and the manufacturing cost is high. If On the premise that the cylinder needs to be used for driving, the manufacturing cost and maintenance cost will be further increased
