Multifunctional quick clamp

Abstract

The invention provides a multifunctional quick clamp. The front end of a main holding rod is provided with a clamping platform. The tail end of the main holding rod is provided with a wrench head. A first connecting rod is connected to the position, close to the front end, of the main holding rod. One end of the first connecting rod is connected with the main holding rod through a rotary shaft. The other end of the first connecting rod is provided with an illuminating device. A screw hole is formed in the position, close to the illuminating device, of the first connecting rod. A lock rod is uniformly provided with a thread. The lock rod is screwed into the screw hole through the thread. The lower end of the lock rod is fixedly provided with a pressing block. Two quick clamps reach the deadpoints simultaneously to achieve the effect of dual self-locking after a workpiece is clamped by adjusting the length of the lock rods. The defect of poor self-locking performance of a common quick clamp is eliminated. The handholding end is far from the pressing point, and the problem of interference between the handholding end and the workpiece in the clamping process can be avoided. The usagereliability of the quick clamp is improved. The application range of the quick clamp is enlarged. The multifunctional quick clamp can provide illumination under poor light and also has the functions of a wrench.

Description

technical field [0001] The invention belongs to the field of clamps, in particular to a multifunctional quick clamp. Background technique [0002] As a manual quick clamping mechanism, quick clamps are widely used in machinery and automobile industries, especially in welding tooling, inspection tooling, and machining. The quick clamp utilizes the dead point position formed when the connecting rod of the planar four-bar mechanism is in line with the follower to realize self-locking. It has the characteristics of simple structure and quick action. Although the quick clamp has the above advantages, it also has the following problems: 1. The reliability of self-locking is relatively poor, and when the vibration is large and the working time is long, the mechanism is prone to loosening from the dead point position; 2. .Limited by the structure of the quick clamp, it is not convenient for remote operation. When encountering remote operation or obstacles in the middle of the clamp...

Problems solved by technology

Although the quick clamp has the above advantages, it also has the following problems: 1. The reliability of self-locking is relatively poor, and when the vibration is large and the working time is long, the mechanism is prone to loosening from the dead point position; 2. .Limited by the structure of the quick clamp, it is not convenient for remote operation. When encountering remote operation or obstacles in the middle of the clamped workpiece, the operation is very difficult, resulting in low work efficiency; 3. Due to the large restrictions on the shape of the workpiece, If the setting position is improper, there will be workpiece interference problems during operation
