[0011] Description of reference numerals:

[0012] 1 tailstock, 2 mounting slot, 3 rotating shaft, 4 cutter head, 5 cutter, 6 gear ring, 7 rotating motor, 8 driving gear, 9 infrared transmitter, 10 bracket, 11 infrared receiver, 12 control panel, 13 top cylinder, 14 latch, 15 latch hole. DETAILED DESCRIPTION

[0013] The present invention will be further described below with reference to the accompanying drawings.

[0014] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0015] See Figure 1 A tool changing device for a tailstock of a machine tool comprises a tailstock 1, a mounting groove 2 is provided inside the tailstock 1, a rotating shaft 3 is provided between the left and right inner walls of the mounting groove 2, a cutter disc 4 with a circular structure is provided on the rotating shaft 3, four tools 5 are provided at equal intervals outside the cutter disc 4, a gear ring 6 is provided on the surface of the cutter disc 4, a rotating motor 7 is provided on the outside of the tailstock 1, the output shaft of the rotating motor 7 extends into the mounting groove 2, and a driving gear 8 is provided, and the driving gear 8 is meshed with the gear ring 6 for transmission connection. Specifically, when the tool 5 needs to be replaced, it is only necessary to start the rotating motor 7, and the driving gear 8 drives the gear ring 6 to rotate, thereby driving the cutter disc 4 to rotate, and the required tool is rotated to the front and then stopped. The whole process is simple and effective, which simplifies the tool changing process and improves work efficiency. The rotating motor 7 is preferably a stepping motor or a servo motor, which is easy to set up and control.

[0016] In this embodiment, four infrared emitters 9 are mounted on the outer end surface of the driving gear 8, each positioned corresponding to a cutting tool 5. A bracket 10 is positioned within the mounting slot, and an infrared receiver 11 is mounted on the bracket 10. The infrared emitters 9 and receiver 11 enable the cutterhead 4 to rotate more precisely, facilitating the use of the cutting tools.

[0017] In this embodiment, a control panel 12 is provided on the side of the tailstock 1. The control panel 12 is used to set and control the rotary motor 7, the infrared transmitter 9 and the infrared receiver 11.

[0018] In this embodiment, a push cylinder 13 is provided at the bottom of the mounting groove 2, and a latch 14 is provided at the end of the piston rod of the push cylinder 13. A plurality of latch holes 15 are provided on the cutter disc 4, each of which corresponds to a cutting tool, and the latches 14 engage with the latch holes 15. After the cutter disc 4 is rotated into position, the push cylinder 13 is activated, inserting the latch 14 into the latch holes 15, thereby further securing the cutter disc 4 and ensuring normal use of the cutting tools.

[0019] The above are only used to illustrate the technical solution of the present utility model rather than to limit it. Any other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solution of the present utility model shall be covered within the scope of the claims of the present utility model as long as they do not depart from the spirit and scope of the technical solution of the present utility model.
