Detailed Description

In order to make the technical means of the present invention clearer and to implement the present invention according to the content of the specification, the following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples, which are used for illustrating the present invention and are not intended to limit the scope of the present invention.

As shown in fig. 1-2, the utility model particularly relates to a flexible clamping device, including base 100, base 100 is provided with centre gripping subassembly 200, centre gripping subassembly 200 is provided with two sets ofly, improves centre gripping quantity, improves work efficiency. The clamping assembly 200 comprises a fixed block 201 and a moving block 202, and the base 100 is further provided with a driving member 300 for driving the moving block 202 to approach or depart from the fixed block 201. The two sides of the lower end of the moving block 202 are provided with convex ribs 203, the base 100 is provided with a sliding groove 101, and the convex ribs 203 can be arranged in the sliding groove 101 to slide. The driving member 300 comprises an air cylinder 301 and an elevating block 302 fixedly connected to the moving end of the air cylinder 301, and the shape of the elevating block 302 is set to be a trapezoid shape. The moving block 202 is tangential to the sidewall of the lifting block 302.

Example 1:

a positioning block 400 is arranged on one side, close to the fixed block 201, of the moving block 202, an elastic part 500 is arranged between the positioning block 400 and the moving block 202, the elastic part 500 is a spring, one end of the spring is fixedly connected with the positioning block 400, the other end of the spring is fixedly connected with the moving block 202, the moving end of the air cylinder 301 moves downwards to drive the lifting block 302 to move downwards, the contact surface between the lifting block 302 and the moving block 202 is inclined, the moving block 202 moves towards the direction of the fixed block 201 under the action of force to clamp materials, and at the moment, the spring is in a compressed state; after the processing is finished, the moving end of the cylinder 301 moves upwards to drive the lifting block 302 to move upwards, the lifting block 302 leaves the moving block 202, and at the moment, the spring in a compressed state pushes the moving block 202 to move towards the direction of the lifting block 302, so that the material is loosened.
