[0026] like Figures 3 to 9As shown, the assembly tray 29 is provided with mounting tubes 38 arranged in a circular array, and the mounting tubes 38 are used to install and place the cutting tools; a snap-fit ​​groove is provided at the mounting handle of the cutting tools; a snap-fit ​​rod 43 is provided inside the mounting tube 38, and a spherical snap-fit ​​rod 45 that snaps with the snap-fit ​​groove is provided at one end of the snap-fit ​​rod 43, and a roller 44 is provided at the other end of the roller 44; and an extrusion ramp 48 is slidably provided inside the mounting tube 38, and the extrusion ramp 48 and the roller 44 are in a contact extrusion relationship; an elastic force detector 40 is provided at one end inside the mounting tube 38, and a contact plate 42 is slidably provided inside the mounting tube 38, and the contact plate 42 is connected to the elastic force detector 40 through a detection spring 41; when the cutting tool is installed in the mounting tube 38, one end of the cutting tool is squeezed The contact plate 42 is pressed to compress the detection spring 41; a release hole 4201 and a detection hole 4202 are provided on the contact plate 42; a spring 1 46 for providing a reset elastic force is sleeved on the spherical buckle rod 45, and a spring 2 47 for providing a reset elastic force is sleeved on the extrusion ramp 48; a slot for allowing the push rod 37 to pass through is opened at one end of the mounting tube 38, and the push rod 37 is passed through the detection hole 4202 to push the end of the tool, and the elastic force of the detection spring 41 is fed back through the elastic force detector 40 to detect whether the tool is stably installed in the mounting tube 38; the push rod 37 is passed through the release hole 4201 to push the extrusion ramp 48, so that the locking rod 43 slides, and then the spherical buckle rod 45 releases the locking of the tool.

[0027] The working principle of the present invention is as follows: various processing tools are placed and installed in the installation tube 38, and the ball-shaped buckle rod 45 is buckled with the buckling groove at the tool installation handle to fix the tool. At the same time, the end of the tool presses the contact plate 42 to compress the detection spring 41; in a processing procedure, the tool to be used is transferred and placed, that is, the screw motor 12 is operated, the moving screw 13 is rotated, and the control part slides to the corresponding assembly disk 29, and then the meshing control electric cylinder 15 controls the meshing gear 23 to mesh with the corresponding adjustment gear 32, and the meshing motor 22 is operated to rotate the assembly disk 29 to adjust the target tool to the clamping position; it should be noted that when the assembly disk 29 does not rotate, the fixed plate 31 is controlled by the fixed electric cylinder 30 to fix the assembly disk 29 to ensure its stability; when the tool is disassembled, the adjustment motor 17 is operated, the adjustment screw 19 is rotated, and the adjustment slide 18 slides. Under the connection action of the adjustment connecting rod 20, the lifting slide 21 and the lifting slide 21 are lifted. The lowering adjustment plate 33 slides so that the position of the push rod 37 corresponds to the end position of the mounting tube 38; the control electric cylinder 14 controls the spacing, and the push rod 37 enters the interior of the mounting tube 38. When the push rod 37 passes through the release hole 4201 and pushes the extrusion ramp 48, the extrusion ramp 48 squeezes the push roller 44, and then the buckling rod 43 and the spherical buckle rod 45 move, and the spherical buckle rod 45 is disengaged from the buckling groove at the tool mounting handle to release the tool; the tool is clamped and transferred by the clamping member, that is, the electromagnetic clamp 28 clamps the tool, the deflection electric cylinder 27 deflects, so that the tool faces upward, and the tool is placed and installed in the adsorption and fixing tube 10, and the adsorption and fixing tube 10 adsorbs and fixes the tool; according to the above process, the tools required for processing are placed and installed in the adsorption and fixing tube 10 one by one. When replacing the tool, the buckling rod 43 works, and the transfer electric cylinder 7 clamps the tool to realize the replacement of the tool; in this way, the tool can be replaced in a short time, saving the time used for long-distance transportation of the tool.

[0028] When the installation of the tool is detected, that is, in the detection mode, in order to detect whether the tool is stably placed and installed on the installation tube 38, through the above process, the push rod 37 is located inside the installation tube 38, and the rotating ring 3301 is rotated by rotating the electric cylinder 34.
