Handheld fixture

Abstract

The invention discloses a handheld fixture. The handheld fixture comprises a body, a first positioning pin, a first side face supporting block and a second side face supporting block, wherein the first positioning pin is arranged at one end of the body; the first side face supporting block is arranged at the other end of the body, and the side, away from the first positioning pin, of the first side face supporting block forms one inclined plane; and the second side face supporting block is arranged on the body and located between the first positioning pin and the first side face supporting block, and the side, facing the first positioning pin, of the second side face supporting block forms one inclined plane. According to the handheld fixture, an air cylinder and other structures are not needed, therefore, the handheld fixture is simple and portable in structure, most structures of the handheld fixture adopt modular design, all parts are independent with each other and convenient to install, therefore, the handheld fixture has better universality, and meanwhile, the development and fabrication time and cost of the handheld fixture are both reduced.

Description

technical field [0001] The present invention relates to hand grippers. Background technique [0002] Welding fixtures are an important means to ensure the accuracy of auto parts, and reasonable positioning and pressing forms are the key to fixture design. [0003] In existing fixture units such as figure 1 As shown, the fixture is generally composed of base 1', pattern plate, clamp 2', cylinder 3', etc. However, when the structure of the workpiece is complex or the size of the fixture is large, the development cost is high, the cycle is long, and the flexibility Low. Among the sub-assembly parts of the automobile body, the size of the front floor assembly is large, and the design size of the fixture is correspondingly large, resulting in high development costs and long cycle times. Contents of the invention [0004] The object of the present invention is to provide a hand-held clamp, which is light and flexible, has a short development cycle and low manufacturing cost. ...
