[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-4 This utility model provides a technical solution:

[0020] A titanium alloy tube piercing machine includes a working platform 1. A liquid collection box 2 is fixedly connected to the top of the working platform 1. A limiting frame 3 is provided on the top of the liquid collection box 2. A positioning bracket 4 is fixedly connected to the left front end of the limiting frame 3. A drive motor 5 is fixedly installed at the middle front end of the positioning bracket 4. A gear 6 is provided in the gap between the positioning bracket 4 and the limiting frame 3 and is fixedly connected to the output end of the drive motor 5. A gear ring 7 is meshed with the right side of the gear 6 and is rotatably connected to the limiting frame 3. An annular groove 8 is opened on the front end face of the gear ring 7. A positioning hoop 9 is fitted inside the annular groove 8. A cleaning cotton sleeve 10 is glued to the inside of the positioning hoop 9. A protruding post 16 is fixedly connected inside the outwardly protruding semi-circular groove of the annular groove 8 and is engaged with the outwardly protruding end of the positioning hoop 9.

[0021] like Figure 1 and Figure 2As shown in the figure, a vertical frame 17 fixedly connected to the liquid collection box 2 is provided behind the defined square box 3. The left and right sides of the liquid collection box 2 are slidably connected with a liquid collection extraction box 15. The liquid collection box 2 and the defined square box 3 are connected through a short elbow pipe. When waste liquid is generated during the operation of the equipment, the waste liquid originally accumulated inside the defined square box 3 will be sent into the liquid collection extraction box 15 provided inside the liquid collection box 2 through the inside of the short elbow pipe to achieve collection. An inner support platform 14 fixedly connected to the liquid collection box 2 is provided at the middle and lower position of the inner bottom of the defined square box 3. Inner vertical plates 11 are fixedly connected to the upper left and upper right sides inside the defined square box 3. An adjustment screw rod 12 is threadedly connected to the middle position of the inner vertical plate 11. The adjustment screw rod 12 is threadedly connected to the defined square box 3. One side of the adjustment screw rod 12 close to the center position inside the defined square box 3 is fixedly connected with a defined clamping plate 13. There are two defined clamping plates 13 in total. When the titanium alloy pipe to be processed passes through the cleaning structure and is inserted and placed inside the defined square box 3, the two adjustment screw rods 12 can be adjusted by screwing, so that the defined clamping plates 13 can move in the same direction, so as to clamp and hold the titanium alloy pipe to be processed. A lifting platform 18 is slidably connected above the vertical frame 17. An electric discharge machining perforation main machine 19 is fixedly installed at the front lower position of the lifting platform 18. The traction end on the left side of the lifting platform 18 is fixedly connected with a drag chain traction module 21 fixedly installed on the left end face of the vertical frame 17. A positioning plate 20 is fixedly connected to the front middle and lower position of the vertical frame 17. The positioning plate 20 and the electric discharge machining perforation main machine 19 are arranged opposite to each other in the up and down positions. When the equipment starts the electric discharge machining perforation main machine 19 for perforation processing, the setting of the positioning plate 20 can play a role in guiding and assisting.

[0022] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, the four convex columns 16 are distributed in an annular array structure. The outer end of the positioning hoop 9 and the inner end of the annular groove 8 are shaped to fit. The rear end of the cleaning cotton sleeve 10 extends into the inner deep hole of the toothed ring 7. The longitudinal part of the positioning bracket 4 is arranged in a "middle" character structure. After the wiping and cleaning structure is used for a period of time, the setting of the clamping connection between the convex column 16 and the positioning hoop 9 is beneficial for the staff to conveniently disassemble and clean the cleaning cotton sleeve 10.

[0023] Workflow: The electrical energy required for the equipment to start and run in this utility model comes from an external power source. Before using the equipment, the two adjusting screws 12 need to be turned in opposite directions to increase the distance between the two limiting clamps 13. The reserved water inlet at the front end of the positioning plate 20 and the working fluid delivery pipeline also need to be connected. When using this piercing machine during the production and processing of titanium alloy tubes, first align the hollow hole of the toothed ring 7 and insert the titanium alloy tube to be processed, allowing it to penetrate the toothed ring 7. Inside the cleaning cotton sleeve 10, the two pre-drilled holes on the front and rear of the limiting frame 3 are precisely inserted to achieve precise placement and tight fit with the inner surface of the cleaning cotton sleeve 10. It is also supported by the inner support platform 14. Then, under the connection limitation of the inner upright plate 11, the two adjusting screws 12 are turned in the same direction, causing the two limiting clamps 13 to move in the same direction. Once in place, they clamp and fix the titanium alloy tube to be processed. Then, under the connection limitation of the upright frame 17, the equipment starts the drag chain traction module 21 to lift the platform 1. 8. The device performs traction and lifting, allowing the electrode head at the bottom of the EDM drilling host 19 to precisely insert into the positioning plate 20 and move downwards, making contact with the titanium alloy tube to be processed. Simultaneously, as the working fluid flows through the interior of the positioning plate 20 and gradually onto the electrode head of the EDM drilling host 19, the device performs drilling on the titanium alloy tube. After completing the entire drilling operation, the limiting clamp 13 is reversed again to facilitate manual removal of the titanium alloy tube, with manual operation assistance. As the workers pull out the processed titanium alloy tube from back to front, during the process of pulling out a certain length, under the connection and limitation of the positioning bracket 4, the drive motor 5 is started to rotate with the gear 6. Under the setting of meshing transmission connection, the gear ring 7 will rotate synchronously with the cleaning cotton sleeve 10 through the positioning hoop 9. This allows the equipment to wipe the gray-black waste liquid remaining on the surface of the titanium alloy tube in advance through the cleaning cotton sleeve 10 during the process of pulling out the titanium alloy tube, so as to avoid the gray-black waste liquid being carried out and dripping onto the processing table of the equipment.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
