Description

Technical Field

[0001] The utility model relates to the technical field of tooling fixtures, in particular to a tooling fixture with a positioning function. Background Art

[0002] A fixture is a process device used to quickly fasten the workpiece during processing to keep the machine tool, tool and workpiece in the correct relative position. In other words, fixtures are indispensable parts of mechanical processing. Driven by the development of machine tool technology towards high speed, high efficiency, precision, compound, intelligent and environmentally friendly, fixture technology is developing towards high precision, high efficiency, modular, combined, universal and economical directions. The machining accuracy and efficiency of the workpiece can be guaranteed through fixtures.

[0003] The China Patent Network discloses a tooling fixture with a quick positioning function. The publication number of the scheme is: CN214264732U, which includes a support table, a support rod is connected to the bottom of the support table, a tooling processing table is connected to the top of the support table, a motor is connected to one side of the tooling processing table, a first sliding plate is connected to the top of the tooling processing table, a fixing bolt is connected inside the first push plate, a transmission shaft is connected to one side of the motor, a slide rail is connected to one side of the transmission shaft, a limited block is connected to one side of the slide rail, a threaded slider is connected to the threaded surface, and a second electric push rod is connected to one side of the second sliding wheel. The first fixing plate and the second fixing plate can be disassembled by fixing bolts. It is suitable for various structural fixtures. Through the structural cooperation of the motor, the threaded slider, the slide rail and the thread, the threaded slider can move freely in the slide rail, which is convenient for workers to replace parts. When it moves to the limit block and cannot move, the positioning work of the fixture is completed, avoiding the positioning deviation of the fixture caused by repeated positioning of workers.

[0004] The solution also has the following problem: it is impossible to perform clamping and positioning operations on workpieces of different widths, so that after the two sides of the workpiece are fixed, slight shaking is likely to occur on both sides, causing deviations in the positioning and stamping of the workpiece.

[0005] Therefore, we proposed a fixture with positioning function to solve this problem. Utility Model Content
