Mechanical clamp for mechanical automatic production and capable of conveniently and automatically controlling clamping force

Abstract

The invention provides a mechanical clamp for mechanical automatic production and capable of conveniently and automatically controlling clamping force. A fan blade plate is fixed to the arc-shaped contour of an output shaft, and a first connecting sleeve is fixed to the front end of the output shaft; the inner wall of the first connecting sleeve is connected with a rotating rod; a transverse rod is connected with a first sliding sleeve; a vertical rod is fixed to the first sliding sleeve; the surface of the vertical rod is connected with a second sliding sleeve; a connecting base is fixed to the rear side of the second sliding sleeve; the inner wall of the connecting base is connected with one end of the rotating rod through a pin shaft; the surface of the rotating rod is sleeved with a first compression spring; the two ends of the first compression spring are fixedly connected with the opposite sides of the connecting base and the first connecting sleeve; the surface, close to the bottom, of the vertical rod is connected with a rotating plate; the side face, close to the top, of the rotating plate is connected with a first clamping plate; the surface of the vertical rod is sleeved with a second connecting sleeve; the top of the second connecting sleeve is connected with the bottom of the second sliding sleeve; limiting plates are fixed to the front side and the rear side of the second connecting sleeve; the opposite sides of two second clamping plates are connected with air bags; a material stirring device is arranged on the first clamping plate; and a feeding device is arranged on the material stirring device. Automatic taking and placing, subsequent collecting and quantitative material feeding can be achieved.

Description

technical field [0001] The invention relates to an automatic mechanical clamp, in particular to a mechanical clamp for automatic mechanical production which is convenient for automatic control of clamping strength, and belongs to the technical field of clamp equipment. Background technique [0002] Fixture refers to the device used to fix the processing object in the process of mechanical manufacturing so that it can occupy the correct position to accept construction or inspection, also known as fixture. In a broad sense, any process in the process, the device used to install the workpiece quickly, conveniently and safely, can be called a fixture. [0003] The fixture usually consists of a positioning element (to determine the correct position of the workpiece in the fixture), a clamping device, a tool setting guide element (to determine the relative position of the tool and the workpiece or to guide the direction of the tool), and an indexing device (to enable the workpiece...

AI Technical Summary

Problems solved by technology

The fixtures currently on the market are not only complex in structure, but also have single functions. There is no hydraulic device. Generally, the items to be processed are heavy, and the hydraulic device cannot provide a large driving force, so that the object to be processed cannot be clamped quickly, which cannot meet the needs of use. It is inconvenient to use; there is no clamping force sensor, and the required clamping force cannot be set through an external control panel, which is not smart to use; for this reason, people propose a fast tooling fixture with adjustable clamping force, such as Chinese patent 2018 A kind of publication number CN105798344B disclosed on October 12, 2010 is a fast tooling fixture with adjustable clamping force, which includes a chuck type clamp body, a small disc body and a clamping force sensor, and the external setting of the clamping force sensor is There is a hydraulic mechanical gripper, the right side of the hydraulic mechanical gripper is provided with a drilling template, and the inside of the drilling template is provided with a hydraulic device, which improves the work efficiency; it can sense the hydraulic mechanical gripper used when clamping objects The clamping force can be obtained, and the required clamping force can be set through the external control panel, and the use is intelligent and precise;

[0004] However, in the actual use process, it is difficult for traditional mechanical fixtures to clamp, move, release and select materials in an integrated manner, and often requires manual assistance or manipulation. The degree of automation is low, which brings inconvenience to use.
