[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 This utility model provides a technical solution: a pin-type automatic positioning and clamping device, including: a cyclone cylinder 1; a guide tube 2 is fixedly connected to one end of the cyclone cylinder 1, and a placement groove 5 is opened at one end of the guide tube 2, and a clamping mechanism is provided in the placement groove 5.

[0022] The clamping mechanism includes a telescopic clamping rod 4 slidably disposed in the guide tube 2 and a positioning block 10 fixed in the placement groove 5. The outer wall of the positioning block 10 has an insertion port. One end of the telescopic clamping rod 4 is barbed and is inserted into the insertion port of the positioning block 10. One end of the telescopic shaft of the cyclone cylinder 1 is fixed with a floating joint 3. One end of the floating joint 3 is hinged to the telescopic clamping rod 4.

[0023] The cyclone cylinder body 1 is a type of cylinder. It controls the up-and-down movement of the lifting and retracting clamping rod 4 in the clamping mechanism through the telescopic shaft, so that the barb end of the lifting and retracting clamping rod 4 can move in the insertion port of the positioning block 10. The positioning block 10 is used for positioning and placing irregularly shaped workpieces. The barb of the lifting and retracting clamping rod 4 works together with the positioning block 10 to clamp the irregularly shaped workpieces.

[0024] In a further preferred embodiment, the outer wall of the lifting and clamping rod 4 is provided with a curved sliding opening 7, and one end of the guide tube 2 is fixed with a limiting pin 8, which passes through the curved sliding opening 7 of the lifting and clamping rod 4 and penetrates the guide tube 2.

[0025] The curved sliding opening 7 of the lifting clamping rod 4, in conjunction with the fixed limit pin 8, causes the lifting clamping rod 4 to have a swinging motion that follows the trajectory of the curved sliding opening 7 when it moves up and down, so that when it rises to release the workpiece of the positioning block 10, it can push the workpiece of the positioning block 10 upward.

[0026] More preferably, a reserved groove 6 is provided in the conduit 2 near the telescopic shaft of the cyclone cylinder 1, and the connection between the telescopic shaft of the cyclone cylinder 1 and the lifting clamping rod 4 is located in the reserved groove 6;

[0027] The pre-reserved groove 6 of the conduit 2 is suitable for the telescopic shaft of the cyclone cylinder 1, so that it has enough space to drive the lifting clamping rod 4 to move up and down.

[0028] In a further preferred embodiment, two symmetrical air pipe joints 9 are fixed on the outer wall of the cyclone cylinder 1. The cyclone cylinder 1 is connected to an external air pipe through its air pipe joints 9 to ensure the required gas flow.

[0029] One specific application of this embodiment is as follows: After the irregularly shaped automotive workpiece is positioned on the positioning block 10 at one end of the guide tube 2, the cyclone cylinder 1 is also ventilated through the external air pipes of the two air pipe connectors 9. After automatic air supply, the barb end of the lifting clamping rod 4 automatically presses down in the insertion port of the positioning block 10, cooperating with the positioning block 10 to clamp the irregularly shaped workpiece, thereby assisting in its precise positioning in the XYZ direction. When removing the irregularly shaped workpiece after processing, the air pipe connectors 9 of the cyclone cylinder 1 are ventilated through the external air pipes, causing the clamping positioning block 10 to automatically release and eject the irregularly shaped workpiece, which is suitable for the precise positioning and clamping of irregularly shaped automotive workpieces.
