Embodiment Construction

[0016] All the curved baffles 1 are covered with flexible airbags 2 , and the curved baffles 1 also have air inlets and air outlets that pass through the curved baffles 1 and communicate with the flexible airbags 2 . The air intake hole is connected to the air pump 4, and the air outlet hole is connected to the air outlet regulating valve 4. The air outlet regulating valve 4 can be a solenoid valve equipped with a wireless transmission module for wireless communication with the controller. In order to better control the clamping degree, a pressure sensing sheet 3 is provided on the working surface where the flexible airbag 2 is in contact with the workpiece. The pressure sensing sheet 3 and the air pump 4 are respectively connected to the controller with wireless signals. 3 The transmitted signal judges whether the clamped part is clamped, and the clamping degree is controlled by adjusting the air pump 4 and the air outlet regulating valve 4.

Abstract

The invention discloses a flexible fixture applicable to workpieces with irregular shapes. The flexible fixture is characterized by comprising at least two arc-shaped baffle plates which are bent toward a clamped workpiece; each arc-shaped baffle plate is covered with a flexible air bag; each arc-shaped baffle plate is provided with an air inlet and an air outlet which communicate with the corresponding flexible air bag; each air inlet is connected with an inflation pump; each air outlet is connected with an air outlet adjusting valve; the working surface, which is in contact with the workpiece, of each flexible air bag is provided with a pressure sensing sheet; the pressure sensing sheets, the inflation pumps and the air outlet adjusting valves are separately connected with a controller through wireless signals; and the controller determines whether the clamped workpiece is tightly clamped or not according to signals transmitted by the pressure sensing sheets and controls a clamping degree by adjusting the inflation pumps and the air outlet adjusting valves. By adopting the flexible fixture, the probability that a workpiece with high brittleness is damaged can be effectively reduced; and furthermore, for a workpiece with an irregular shape, the flexible air bags can effectively cling to the outer surface of the workpiece, so that the clamping degree is improved.

Description

technical field [0001] The invention relates to a fixture, in particular to a flexible fixture suitable for workpieces with irregular shapes. Background technique [0002] In the prior art, there is a fixture for horizontally fixing workpieces, which mainly includes a workbench and a baffle on the workbench. The baffle is driven by a driving device and can move relative to the workbench to realize workpiece clamping or loosening. However, in the process of mechanical production and manufacturing, it is usually encountered that irregular workpieces need surface processing. For the above-mentioned fixtures, the working surface and the workpiece are mostly in hard contact. For workpieces with high brittleness and irregular shapes, This kind of fixture is easy to cause damage to the clamped workpiece, reduces the qualified rate of products, and affects production efficiency. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencie...
