Description

Technical Field

[0001] This utility model relates to a motor and an integrated device for machining the thread of a screen hole pipe used for coal mine gas drainage, belonging to the field of pipe machining technology. Background Technology

[0002] Gas drainage is a core component of the "drainage before mining" safety production policy in coal mines. As a crucial carrier of gas, the gas drainage pipeline requires perforated pipes at the end of the system before it enters the coal face to ensure proper gas discharge. The quality of the perforated pipes directly affects the sealing and safety of the gas drainage system. Currently, the production process of perforated pipes for coal mine gas drainage primarily relies on different decentralized equipment and processes.

[0003] The current processing method for perforated pipes requires multiple machines to complete the process in steps: First, during pipe production, an online drilling machine is used to drill radial holes at preset positions on the pipe body. Operators then transport the drilled pipes to the welding workshop for storage. Subsequently, an injection molding machine is used to produce a certain number of pipe thread fittings. After the pipe fittings are produced, the pipes and fittings are finally heat-fused and welded manually to complete the processing of the perforated pipes used for coal mine gas drainage. This process has significant drawbacks: First, the transportation process is time-consuming and labor-intensive, requiring multiple handling operations for each pipe and consuming 2-3 operators. Second, the processing cycle is long; the average processing time for a single pipe using traditional methods typically exceeds 10 minutes, making it difficult to meet the demands of high-efficiency production.

[0013] like Figure 1As shown, a thread processing motor and thread processing integrated device for coal mine gas drainage screen holes include a frame 1, an operating table 2, and a thread processing motor 3. The operating table 2 is installed in the middle of the frame 1, and a transverse movement mechanism 4 is installed on both sides of the operating table 2. The thread processing motor 3 is installed on the transverse movement mechanism 4. The output shaft of the thread processing motor 3 is concentrically arranged, and a tapping head 5 is installed on the output shaft of the thread processing motor 3.

A drilling lifting mechanism 9 is installed on the fixing frame 7. An L-shaped fixing plate 10 is installed on the drilling lifting mechanism 9. Multiple drilling motors 11 are installed on the L-shaped fixing plate 10. A drill bit 12 is installed on the output shaft of the drilling motor 11.

[0014] This invention employs an operating platform 2 installed within a frame 1. The operating platform 2 houses a pipe clamping and fixing mechanism 6, and thread-processing motors 3 and a transverse movement mechanism 4 are mounted on both sides. The thread-processing motors 3 can reciprocate on the transverse movement mechanism 4. The pipe clamping and fixing mechanism 6 secures the pipe to be processed. The drilling lifting mechanism 9 controls the synchronous up-and-down movement of multiple drilling motors 11 on an L-shaped fixing plate 10, and processes the pipe through the drilling motors 11. The transverse movement mechanism 4 drives the thread-processing motors 3 to tap the pipe.

[0015] The transverse movement mechanism 4 includes two guide rods 13 installed between the operating table 2 and the frame 1, and a slide 14 installed on the guide rods. A drive screw 15 is installed between the two guide rods 13. The slide 14 is installed on the drive screw 15 via a connecting nut. A servo motor 16 is installed at the end of the drive screw 15 and is fixed to the frame 1. The transverse movement mechanism 4 uses the servo motor 16 to control the rotation of the drive screw 15, which in turn drives the slide 14 to move, thereby driving the thread processing motor 3 to reciprocate. The thread processing motor 3 drives the tapping head 5 to perform tapping operations on both ends of the pipe to be processed.

The fine-tuning support cylinders 20 are mounted on the operating table 2, and arc-shaped support plates 21 are installed on the piston rods of the fine-tuning support cylinders 20. The pipe clamping and fixing mechanism 6 can fix the pipe to be processed. During fixing, the pipe is first placed on the arc-shaped clamping plates 19 and the arc-shaped support plates 21. Then, the positioning cylinders 17 and the fine-tuning support cylinders 20 are used to adjust the pipe so that it is concentrically aligned with the output shaft of the servo motor 16. Finally, the clamping cylinders 18 clamp and fix the pipe, completing the fixing process.
