Self-centring pneumatic clamp

Abstract

The invention discloses a self-centring pneumatic clamp. The self-centring pneumatic clamp comprises a base, stop blocks, an installation block, clamping jaws, guide rods, a cylinder and a workpiece, wherein the two stop blocks are arranged at one end of the surface of the top of the base; the installation block is fixedly arranged at the other end of the surface of the top of the base; the cylinder is arranged at the outer side of the installation block, and one end of the cylinder penetrates through the centre of the installation block and is in embedded connection with the installation block; the guide rods are installed at the two sides of the cylinder respectively, and one end penetrating through the installation block, of each of the two guide rods, is fixedly connected with one clamping jaw; and the workpiece is clamped between the clamping jaws and the two stop blocks, the stop blocks are fixedly connected with the base through screws, and the two stop blocks are placed at a 90-degree angle. The invention provides a self-centring pneumatic clamp capable of achieving the beneficial effects of meeting the need of carrying out location and clamping on cylindrical and cubic workpieces simultaneously, realizing self-centring clamping for the workpieces, and reducing time waste during a machining process.

Description

technical field [0001] The invention belongs to the technical field of clamps, in particular to a self-centering pneumatic clamp. Background technique [0002] According to the development sequence of the intelligent manufacturing industry chain, intelligent manufacturing first needs to realize automation, then realize informatization, realize Internet again, and finally realize intelligence. Industrial robots are one of the most important tasks in the early stage of intelligent manufacturing, and are an important carrier for linking automation and informatization. [0003] In recent years, due to the more and more widespread use of robots in various industries, more and more projects are replaced by robots for manual production. In order to meet the automation required for robot production, related fixtures and other equipment also need to be automated. Existing cutting fixtures are mainly manually clamped, and the screw is rotated to push the jaws to clamp the workpiece. ...
