[0022] Furthermore, a movable tool 206 is provided at the upper end of the tooling platform 205. Four workstations are provided on the tooling platform 205, which can hold four machine tool movable tooling 206. Each workstation is provided with three conical locating pins to ensure the precise positioning of the movable tooling 206, so that the robot can accurately grasp and load materials. The outer surface of the movable tooling 206 is movably connected to the workpiece 207. A circular locating pin 208 is provided at the upper end of the tooling platform 205. The size and position of the locating pin on the loading and unloading tooling are designed according to the structure of the machine tool movable tooling 206. Since it is a conical locating pin, the accuracy requirements for manual and robot loading do not need to be too high. A PLC control component 209 is provided on the side wall of the tooling bracket 1, and a positioning groove 210 is provided at the bottom end of the movable tooling 206.

[0023] In an embodiment of the present utility model, a plurality of circular positioning pins 208 are provided at the upper end of the tooling platform 205, and the plurality of circular positioning pins 208 are arranged in a circular array at the upper end of the tooling platform 205. The number of positioning grooves 210 is the same as the number of circular positioning pins 208, so that a smooth docking and positioning operation can be performed. The circular positioning pins 208 are adapted to the positioning grooves 210, so that the accompanying tooling 206 can be stably fixed on the tooling platform 205. A cleaning component 3 is provided at the upper end of the tooling platform 205, and the cleaning component 3 includes a sensor 301. In order to automatically identify the presence or absence of the accompanying tooling 206, a detection proximity sensor 301 is installed at each workstation.

[0024] In addition, the sensor 301 is fixedly connected to the upper end of the tooling platform 205, and a high-pressure gas nozzle 302 is provided on the outer wall of the circular locating pin 208. In order to remove the iron filings that may be stuck in the locating pin hole at the bottom of the accompanying tooling 206, which affects the robot's grasping and machine tool processing accuracy, a small hole is opened in the middle of the conical locating pin on the loading and unloading tooling, and high-pressure gas is introduced. When the robot places the accompanying tooling 206, the high-pressure gas is turned on to blow away the iron filings in the locating pin hole at the bottom of the accompanying tooling 206 and on the conical pin. The high-pressure gas nozzle 302 is set at the center of the circular locating pin 208, so that the high-pressure gas in the center hole of the locating pin will be opened, and the iron filings that may be stuck in the locating pin hole at the bottom of the accompanying tooling 206 and on the conical pin will be blown out.

[0025] In the present invention, during daily loading and unloading, the workpiece 207 to be processed is a special-shaped part. Before processing, a pair of workpieces 207 are manually installed on a special machine tool accompanying tooling 206, and then the accompanying tooling 206 is hoisted and placed on the robot loading and unloading tooling. The robot grabs the accompanying tooling 206 and puts it into the machine tool for processing.

In order to automatically identify the presence or absence of the accompanying tooling 206, a detection proximity sensor 301 is installed on each workstation, and finally the two end workstations on the loading and unloading tooling are respectively the manual loading and unloading station and the robot loading and unloading station, and the human-machine operation station is separated, ensuring the human-machine safety in the robot automatic production.

[0026] And when the robot grabs the accompanying tool 206 and puts it into the machine tool for processing, the three groups of circular locating pins 208 and the three groups of locating grooves 210 are used to cooperate so that the accompanying tool 206 can be accurately positioned and placed on the tooling platform 205. A small amount of iron filings may be stuck in the locating grooves 210 at the bottom of the accompanying tool 206. At this time, when the machine tool accompanying tool 206 is accurately placed on the conical locating pin, the proximity sensor 301 will generate a signal to transmit to the system PLC, providing conditions for automatic control, so that when the robot carries the machine tool accompanying tool 206 and is ready to place the conical locating pin, the high-pressure gas in the center hole of the locating pin will open, and the iron filings that may be stuck in the locating pin hole and on the conical pin at the bottom of the accompanying tool 206 will be blown out, ensuring the positioning accuracy, and ultimately greatly increasing the overall practicality.

[0027] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention.
