[0023] Extrusion mechanism 2 includes telescopic cylinder 201, and telescopic cylinder 201 is installed on the side surface of fixed seat 1, and the inner wall of fixed seat 1 is slidably connected with limit rod 202.

[0024] The rotating mechanism 3 includes a fixed shell 301. One side of the fixed shell 301 is fixedly connected to the telescopic end of the telescopic cylinder 201. The same side of the fixed shell 301 is also fixedly connected to a limiting rod 202. A motor 302 is installed inside the fixed shell 301. The output end of the motor 302 is fixedly connected to the cylinder 4. The outer surface of the cylinder 4 is rotatably connected to the fixed shell 301. The extrusion mechanism 2 and the rotating mechanism 3 constitute the power system of the fixture. The cylinder 4 can be moved closer to the workpiece by the telescopic cylinder 201 through the rotating mechanism 3, thereby fixing it. The limiting rod 202 is used to increase the stability of the fixed shell 301 and prevent the fixed shell 301 from tilting or shifting, which could lead to cracking at the connection with the telescopic cylinder 201. When the motor 302 rotates, it can drive the cylinder 4 to rotate. Both the motor 302 and the telescopic cylinder 201 are electrically driven and connected to an external controller.

[0025] The active mechanism 6 includes a sliding plate 601, the outer surface of which is slidably connected to the extrusion plate 5. A support plate 602 is fixedly connected to one side of the sliding plate 601, and a fixing plate 603 is fixedly installed on the other side of the sliding plate 601. A cleaning cloth 9 is sleeved on the outer surface of the support plate 602, and both ends of the cleaning cloth 9 are fixedly sleeved on the ends of the support plate 602. When the cleaning cloth 9 needs to be cleaned, it can be removed from the support plate 602 for replacement. The extrusion plate 5 has a rectangular groove for the sliding plate 601 to slide, the width of which is greater than the width of the support plate 602 and the cleaning cloth 9, so that the cleaning cloth 9 can slide into the rectangular groove of the extrusion plate 5.

A sliding cylinder 702 is slidably connected to the inner wall of the fixed cylinder 701. A first spring 703 is connected to the inner wall of the fixed cylinder 701. The other end of the first spring 703 is connected to the sliding cylinder 702. The fixed cylinder 701 and the sliding cylinder 702 can slide together, thereby extending and shortening. The first spring 703 provides an elastic force to the sliding cylinder 702, causing the sliding cylinder 702 to press against the fixed plate 603.

Under no external force, the end of the pressing element 804 does not contact the pressure sensor 802. When the cleaning cloth 9 is subjected to pressure, the pressing element 804 presses the pressure sensor 802. The pressure sensor 802 transmits the pressure signal to the external controller. The pressing mechanism 2 stops moving before the pressing plate 5 contacts the workpiece.

[0029] The telescopic cylinder 201, electric motor 302 and pressure sensor 802 in this application are common electrical devices in the prior art. This application will not elaborate on their models or internal structures. They can also be replaced by other power sources or sensing components.

[0030] In use, the metal workpiece to be fixed is placed between two extrusion plates 5. The extrusion mechanism 2 drives the extrusion plates 5 and the cleaning cloth 9 to move close to the outer surface of the workpiece. The cleaning cloth 9 first touches the surface of the workpiece. Under the action of the counter-extrusion force, the movable mechanism 6 moves towards the inside of the cylinder 4. Before the extrusion plates 5 contact the workpiece, the extrusion component 804 first extrudes the pressure sensor 802. The pressure sensor 802 transmits the pressure signal to the external controller, thereby controlling the extrusion mechanism 2 to stop moving. At the same time, the rotating mechanism 3 is controlled to drive the cylinder 4 to rotate, so that the cleaning cloth 9 rubs against the outer surface of the workpiece, thereby wiping away the oil stains on the workpiece. Then the rotation stops, and the workpiece is extruded again, so that the extrusion plates 5 contact and extrude with the cleaned workpiece to prevent slippage caused by oil stains, thereby increasing the clamping stability.
