Abstract

The invention provides an automatic clamping tool. The automatic clamping tool comprises a working table, a cylinder and a clamping unit, wherein a containing groove is formed in the middle of the working table, a first pressure sensor is arranged in the containing groove and electrically connected with a controller, the cylinder is fixed above the working table through a support, a piston rod faces downwards and is located over the containing groove, the piston is fixedly connected with a connecting frame, the clamping unit is hinged to the connecting frame through a first articulated shaft and comprises two sets of first clamping rods and clamping plates which are hinged to each other through second articulated shafts, each clamping plate is in threaded connection with a clamping head which is provided with a second pressure sensor, and the second pressure sensors are electrically connected with the controller. According to the automatic clamping tool, a clamping pressure value is set according to specifications of a workpiece, the clamping stability is guaranteed, and the local crushing phenomenon cannot be caused simultaneously; meanwhile, the efficiency and the safety of the clamping operation can be improved.

Description

technical field [0001] The invention belongs to the field of machinery, and in particular relates to an automatic clamping tool. Background technique [0002] In the field of mechanical processing, when turning a workpiece, in order to overcome the turning force of the turning process on the workpiece and ensure high machining accuracy, it is necessary to perform clamping and positioning operations on the workpiece during the turning process. However, the currently used positioning tooling requires the operator to perform manual clamping operations, and it is difficult to quantify the clamping force on the workpiece. Often, local plastic pits are formed on the surface of the workpiece due to excessive local pressure, and sometimes due to insufficient clamping force As a result, the position of the workpiece changes during the machining process, resulting in reduced machining accuracy and even scrapping of the workpiece. Contents of the invention [0003] In view of this, ...
