Problems solved by technology

[0004] Although the existing clamping fixture can meet the clamping requirements of the workpiece to a certain extent, in the actual use process, the inventor found that it still has some shortcomings as follows: 1. One-sided pressure is easy to cause the workpiece to be under processing. The displacement in the process is difficult to achieve the accuracy of positioning; 2. The commonly used clamping fixture combined with the spring can only clamp the workpiece when the spring is in a compressed state, so that the spring needs to be continuously pressed during the clamping process , which is easy to cause waste of resources, increased use cost and continuous pressure clamping makes the whole loading and unloading process complicated, inconvenient loading and unloading and poor self-locking effect

Abstract

The invention relates to a clamping fixture and particularly relates to a bi-directional positioning clamping fixture. The fixture comprises a fixture body, a left clamping jaw and a right clamping jaw which are hinged with the fixture body, a push rod fixedly connected with the left clamping jaw, a strong spring sleeved on the push rod, a sleeve arranged at a transmission end of the thrust rod, a cam used as a force application device, and a linkage pin which has the driving function, wherein the fixture body is provided with a horizontal through hole and an inclined through hole; the push rod penetrates through the horizontal through hole, and the transmission end of the push rod extends to a rectangular groove correspondingly formed at a drive end of the lower part of the left clamping jaw; the linkage pin penetrates through the inclined through hole, and two ends of the linkage pin extend to grooves which are correspondingly formed on the left clamping jaw and the right clamping jaw respectively; the drive end of the left clamping jaw is also provided with a roller; the roller is pressed against the cam; and moreover, one end of the strong spring is connected with the push rod, and the other end of the strong spring is connected with the sleeve; By using the bi-directional positioning clamping fixture in the technical scheme, a workpiece can be positioned accurately and is convenient to assemble and disassemble; and the bi-directional positioning clamping fixture is strong in self-locking performance and low in using cost.

Description

technical field [0001] The invention relates to a clamping device, in particular to a bidirectional positioning clamping fixture. Background technique [0002] In the machining and manufacturing industry, the positioning and clamping fixture plays a very important role. It ensures that the workpiece is always in the correct position relative to the machine tool and cutting tool, and ensures the consistency and quality of the workpiece processing. [0003] The traditional clamping fixture achieves the effect of clamping the workpiece by using a combination of levers, springs, pulleys, cams, and handles. The combination of a cam and a lever to press the workpiece is a common clamping fixture. [0004] Although the existing clamping fixture can meet the clamping requirements of the workpiece to a certain extent, in the actual use process, the inventor found that it still has some shortcomings as follows: 1. One-sided pressure is easy to cause the workpiece to be under processin...
