Clamping rotating device

Abstract

The invention discloses a clamping rotating device. The device comprises a stretching mechanism, a clamping compressing mechanism and a rotating mechanism; during work, a workpiece is ejected in from a center through hole of a round table of an elastic clamping sleeve, a spring is compressed, an air cylinder is ventilated, the elastic clamping sleeve is forced to move along a bearing sleeve in the direction where the air cylinder is located, radial shrinkage is carried out, and the aim of clamping an object is achieved; a synchronous belt wheel does the rotation motion, and the elastic clamping sleeve and the workpiece are driven to jointly do the rotation motion; if the air cylinder carries out exhaust unloads, the elastic clamping sleeve is reset, and the spring is automatically reset and meanwhile ejects out the workpiece. Stable clamping and rotating of the workpiece can be achieved, the problem that due to double clamping grasping, clamping stability is poor, and clamping force is not enough is solved, the control manner that the air cylinder is combined with a mechanical mechanism is adopted in the device, operation is convenient, and the cost is saved.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing equipment, and in particular relates to a clamping and rotating device. Background technique [0002] At present, in the field of industrial automation, there are many clamping devices, such as double clamping, triple clamping, multi clamping and so on. Chinese patent 201310405745.1 discloses a clamping device, which is a double clamping device, including a first clamping arm and a second clamping arm, the first clamping arm and the second clamping arm are hinged to each other, but For the clamping rotary body, the double clamping is not stable enough, and the clamping is not strong enough. [0003] Chinese patent 201320076755.0 discloses a three-claw manipulator. The manipulator pushes the guide block to move along the tapered surface through the sliding of the telescopic rod to control the opening and closing of the claw fingers. It can grab the cylindrical workpiece, but the devi...

[0003] Chinese patent 201320076755.0 discloses a three-claw manipulator. The manipulator pushes the guide block to move along the tapered surface through the sliding of the telescopic rod to control the opening and closing of the claw fingers. It can grab the cylindrical workpiece, but the device does not realize the rotation of the workpiece. and not stable enough

However, the use of robot control greatly increases the cost
