[0015] The utility model is further described below in conjunction with the accompanying drawings.

[0016] As attached Figure 1 As shown, a hot melt tapping device includes a hot melt tapping machine, on which a hot melt drill part 4 and a tapping drill part 5 are arranged on a transverse guide rail 3 of the hot melt tapping machine; a cylinder-driven positioning plate 2 is provided on a working table 1 of the hot melt tapping machine, and when a workpiece 10 is placed on the working table 1, it is surrounded and clamped by the positioning plate 2, and then hot melt and tapping operations are performed, thereby saving nuts and improving production efficiency.

[0017] As attached Figure 1 , Attachment Figure 2 And attached Figure 3 As shown, the utility model includes an air chamber 6 that moves horizontally synchronously with the hot melt drill part 4 and the tapping drill part 5, and an air blowing pipe extending from the air chamber 6 to blow air to cool the hot melt drill bit 40 and the tapping drill bit 50; a pipe sleeve 12 with air holes 120 distributed on the pipe surface is arranged at the top of the air chamber 6, and the air blowing pipe is slidably sealed with the pipe sleeve 12 through a sleeved piston ring 13; the air blowing pipe is driven by the hot melt drill part 4 and the tapping drill part 5 to form a switchable blocking state in which the piston ring 13 covers the air hole 120 and a conducting state in which the piston ring 13 moves down to the bottom of the air hole 120. The air blowing pipe of the utility model is converted from the blocking state to the conducting state driven by the hot melt operation and the tapping operation, thereby providing air cooling with relatively stable airflow for the hot melt drill bit 40 and the tapping drill bit 50 in the working state, which is less affected by the vibration of the equipment operation, and the blown airflow is more stable, thereby improving the cooling effect and extending the service life of the drill bit.

[0018] The utility model includes a clamp connector 9, and the two blowing pipes are respectively connected to the hot melt drill part 4 and the tapping drill part 5 through the clamp connector 9, and the clamp connection position of the clamp connector 9 is the body of the hot melt drill part 4 and the tapping drill part 5. The clamp connector 9 includes a clamp and a locking screw nut, and the outside of the blowing pipe is connected with a connecting plate connected to the clamp, and the clamp is clamped on the body of the hot melt drill part 4 and the tapping drill part 5, and is fastened by the locking screw nut.

[0019] The blow pipe includes a hot melt drill blow pipe 7 fixedly connected to the hot melt drill part 4 and a tap drill blow pipe 8 fixedly connected to the tap drill part 5. The hot melt drill blow pipe 7 and the tap drill blow pipe 8 are alternately connected and blocked with the alternating operation of hot melting and tapping. Since the processing sequence is hot melting first and then tapping, when hot melting is in operation, the hot melt drill blow pipe 7 blows air, while the tap drill blow pipe 8 does not blow air. When tapping is in operation, the tap drill blow pipe 8 blows air, while the hot melt drill blow pipe 7 does not blow air. When blowing is needed, the air is turned on and blown, and when blowing is not needed, the air is blocked and not blown, thereby reducing the gas usage while maintaining a greater flow force of the air flow, and improving the blowing cooling efficiency.

[0020] The air outlet end of the hot melt drill blow pipe 7 is bent toward the hot melt drill bit 40 and has a contraction structure, which concentrates the air flow to increase the blowing force; the air outlet end of the tapping drill blow pipe 8 is bent toward the tapping drill bit 50 and has a contraction structure, which concentrates the air flow to increase the blowing force.

[0021] The bottom of the air chamber 6 is provided with an opening 60 corresponding to the air blowing pipe, and the hot melt drill air blowing pipe 7 and the tapping drill air blowing pipe 8 are arranged through the opening 60. The bottom of the corresponding air chamber 6 and the connecting plate outside the air blowing pipe are connected with a telescopic sealing sleeve 14 that seals the opening 60. The telescopic sealing sleeve 14 can be a telescopic pipe, the upper ring plate of the telescopic pipe is connected to the bottom surface of the air chamber 6, and the lower ring plate of the telescopic pipe is connected to the connecting plate on the air blowing pipe.

[0022] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
