The tooth plate 20 is located on the inner side of the circular plate 12 and is slidably connected to the inner side of the circular plate 12. The brush plate 21 is fixedly connected to the side of the tooth plate 20 without a tooth opening. The center of the left side of the gear 18 is rotatably connected to the five-sided slide plate 22. The five-sided slide plate 22 is slidably connected to the long plate 23, and the long plate 23 is fixedly connected with a clamping column, and the clamping column is inserted into the inner side of the second inclined groove 19 and is slidably connected to the second inclined groove 19. The long plate 23 is fixedly connected to a splint 24 at one end away from the five-sided slide plate 22, and the splint 24 is located inside the slide groove 13 and is slidably connected to the slide groove 13. A fixed cylinder 25 is fixedly connected to the center of the left side of the wheel 18, and the fixed cylinder 25 passes through the center of the five-sided slide plate 22 and is rotatably connected to the five-sided slide plate 22. A first inclined groove 26 is provided on the outer side of the fixed cylinder 25, and the connecting column 15 is inserted into the inner side of the fixed cylinder 25 and is slidably connected to the fixed cylinder 25.

[0061] The working principle of this embodiment is:

[0062] First, when the part presses down on the pressure plate 16, the connecting column 15 is driven to slide inside the fixed cylinder 25. At the same time, the spring 27 is forced into a semi-squeezed state, driving the clamping column 17 to move relatively through the first inclined slot 26 to drive the fixed cylinder 25 to rotate, driving the gear 18 to rotate, driving the clamping column fixedly connected to the long plate 23 and the second inclined slot 19 to slide with each other, and relatively driving the long plate 23 to drive the clamping plate 24 to move, so that the part can be automatically clamped and fixed;

[0063] Secondly, when the gear 18 rotates, it meshes with the tooth plate 20, driving the tooth plate 20 to drive the brush plate 21 to move, and can also simultaneously clean the dust or various waste dusts that fall into the inner side of the chute 13 during processing to the left and right sides of the chute 13, which can also reduce the trouble of subsequent cleaning;

[0064] Third, when it is necessary to adjust the angle, the bolt 101 is manually grasped and rotated to drive the bolt 101 to move toward the outside of the hollow sphere 10, thereby releasing the squeeze on the solid sphere 9. Then, the spherical head body 4 is grasped and moved to the tilt angle, thereby achieving multi-angle adjustment.

[0065] Fourth, at the same time, when the spherical head body 4 is moved at a tilt angle, in order to prevent the parts on the spherical head body 4 from falling off, the upper and lower ends of the tension spring 28 are respectively fixed to the upper end surface of the solid sphere 9 and the lower end surface of the connecting column 15. The spherical head body 4 moves the tension spring 28 elastically pulling the connecting column 15, driving the clamping column 17 to continue to move toward the inner and lower side of the fixed cylinder 25, and at the same time squeezing the spring 27 again, driving the fixed cylinder 25 to rotate through the first inclined groove 26, driving the gear 18 to rotate, and driving the splint 24 through the long plate 23 to further clamp and fix the parts. When the spherical head body 4 is damaged and needs to be replaced, the spherical head body 4 can be easily removed by sliding the clamping plate 6 to disengage the clamping fixation of the base circular plate 7, which is more convenient and simple to use.

[0066] The present invention provides a product positioning mechanism for a multi-axis tapping machine through improvement. When in use, it is only necessary to place the parts on the upper end of the spherical pan-tilt head body 4 so that the parts are in contact with the pressure plate 16. The pressure plate 16 is pressed down by the weight of the parts themselves, which can also automatically drive the splint 24 to automatically clamp and fix the parts. When multi-angle adjustment is required, the squeezing and fixation of the solid sphere 9 can be released by rotating the bolt 101, and rapid multi-axis adjustment can also be achieved. In order to prevent the parts from falling, when adjusting the angle, the circular plate 12 is tilted so that the tension spring 28 pulls the connecting column 15, driving the splint 24 to further clamp and fix the parts to prevent them from falling. When the spherical pan-tilt head body 4 needs to be disassembled, it can be easily removed by sliding the clamping plate 6.
