Description

A quick clamping device

technical field

The utility model relates to a fast clamping device, which belongs to the technical field of mechanical processing.

Background technique

In machining technology, the clamping requirements for the workpiece are very high. The flat-nose pliers usually used in the fitter clamping are used for clamping. It is relatively simple to clamp relatively standardized parts, and the flat-nose pliers are used for complex or irregular parts. Clamping is time-consuming and the clamping is not firm, so the efficiency is low in machining production technology. In order to save production costs and improve production efficiency, it is necessary to design a quick clamping device.

Utility model content

In order to solve the above problems, the purpose of this utility model is to solve the above-mentioned deficiencies in the prior art, and the purpose of this utility model is to provide a quick clamping device.

In order to solve the above problems, the utility model is achieved through the following technical solutions: a quick clamping device, which is composed of a clamping handle 1, a movable jaw 2, a rotary pair 3, a fixed jaw 4, a V-shaped block 5, The workpiece 6, the right positioning pin 7, the connecting plate 8 and the left positioning pin 8 are characterized in that: the lower end of the clamping handle 1 is an eccentric wheel, and the mounting hole in the middle of the eccentric wheel is equal to the positioning pin 8; the movable clamp The right side in the middle of the mouth 2 is V-shaped, and there is a groove at the bottom, the groove width is equal to the width of the connecting plate 7; the rotary pair 3 is installed on the fixed jaw 4; the V-shaped block 5 is installed on the fixed jaw 4 and is an interference fit; the workpiece 6 is installed in the V-shaped block between the movable jaw 2 and the fixed jaw 4; the right positioning pin 7 is installed in the lower positioning hole of the fixed jaw 4 and For interference fit; the connecting plate 8 is installed on the right positioning pin 7 and the left positioning pin 9 . When working, put the workpiece 6 into a pair of V-shaped jaws, pull the clamping handle 1 to the lower left to clamp the workpiece; pull the clamping handle 1 to the upper right to loosen the workpiece, and take out the workpiece.

The beneficial effects of the utility model are: a quick clamping device, which has the advantages of simple structure, convenient operation, low cost, safety and reliability.
