Description

Technical Field

[0001] The present invention relates to the technical field of precision pipe processing, and in particular to a precision pipe processing device and a processing method. Background Art

[0002] The precision pipe fittings produced are widely used as important materials in the fields of construction, petroleum, automobile manufacturing, aerospace, etc., and their processing quality is directly related to the safety and reliability of the final product.

[0003] During the processing of precision pipe fittings, it was found that due to the large weight of the pipe fittings themselves, especially when processing longer pipe fittings, the weight of the pipe fittings will cause them to bend downward during the processing. This bending deformation will not only affect the processing accuracy, but may also cause the processed pipe fittings to not meet quality requirements, increasing the scrap rate. Although existing processing devices have support devices, these support devices are usually fixed and cannot be dynamically adjusted according to the processing position and shape changes of the pipe fittings. Therefore, they cannot effectively solve the problem of bending deformation of the pipe fittings. This fixed support method cannot adapt to the bending deformation of the pipe fittings caused by their own weight during the processing process, resulting in a decrease in processing accuracy and affecting the quality of the final product.

[0004] Therefore, to improve the accuracy and efficiency of pipe processing and reduce bending deformation caused by the weight of the pipe, it is necessary to develop a new type of precision pipe processing device with the ability to dynamically adjust the support device to accommodate the processing needs of pipes of different lengths and shapes. This will help ensure the stability of the pipe during processing, thereby improving processing accuracy and product quality. Summary of the Invention

When the first clamping mechanism 5 and the second clamping mechanism 6 are separated from the clamping fixation of the pipe, the clamping wheel 419 can be driven to rotate under the action of the second motor 417, so that the clamping wheel 419 can drive the pipe to be transported out from one end of the machine tool body 1, which is conducive to assisting manual extraction of the pipe and improving the convenience of the unloading operation.

[0026] Working Principle: First, insert one end of the pipe to be processed into the first pneumatic chuck 502 to secure it. Then, the fourth motor 504 drives the fourth threaded rod 503 to rotate, adjusting the position of the movable base 501 and the first pneumatic chuck 502 to accommodate pipes of varying lengths. Next, manually rotate the handle 406, driving the second threaded rod 405 to adjust the position of the processing platform 404 and the tool 407, aligning them with the processing area of the pipe.

[0027] Simultaneously, the second pneumatic chuck 602 secures the end of the pipe, and the fifth motor 605 drives the sleeve 603 to rotate, ensuring uniform rotation during machining. As the pipe rotates, the first motor 401 is activated, driving the first threaded rod 402, which in turn moves the positioning seat 403 along the threaded direction, enabling the tool 407 to machine different locations on the pipe's outer wall.

[0028] During machining, the first spring 302 in the support mechanism 3 automatically adjusts the position of the sliding frame 304 and the lifting frame 303, allowing them to slide horizontally and evenly distribute themselves across different locations on the pipe. The support block 308 and support rod 309 at the top of the lifting frame 303 evenly support the bottom of the pipe, preventing it from bending downward due to its own weight, thereby ensuring machining accuracy.

[0029] In addition, the infrared distance sensor 313 in the detection assembly monitors the distance changes between the outer wall of the pipe and the support block 308 in real time. If the infrared distance sensor 313 detects that the pipe is bent or deformed during processing, it will feedback the signal to the controller 2, reminding the operator to trim the pipe in time before continuing processing.

[0030] After processing is complete, the sixth motor 415 drives the third threaded rod 413 to rotate, causing the first slider 411 and the second slider 416 to move relative to each other, thereby clamping the pipe with the guide wheel 412 and the clamping wheel 419. After the first clamping mechanism 5 and the second clamping mechanism 6 release their grip on the pipe, the second motor 417 drives the clamping wheel 419 to rotate, transporting the pipe from one end of the machine tool body 1, completing the unloading operation. The coordinated operation of these various mechanisms throughout the entire processing process achieves efficient and stable pipe processing, suitable for processing pipes of various specifications.

[0031] Example 5: This embodiment provides a method for processing precision pipes using the above-mentioned processing apparatus, and the specific process is as follows: S01. One end of the precision pipe to be processed is inserted into the first pneumatic chuck 502 for fixing; S02 driven by the fourth motor 504 to rotate the fourth threaded rod 503 to adjust the position of the movable seat 501 and the first pneumatic chuck 502 to adapt to pipes of different lengths; S03. Turn the handle 406, by rotating the second threaded rod 405 to adjust the position of the processing platform 404 and the tool 407; S04 using the second pneumatic chuck 602 to fix the end of the pipe, and through the fifth motor 605 drives the sleeve 603 to rotate, so that the pipe rotates; S05 starts the first motor 401, through the rotation of the first threaded rod 402 drives the positioning seat 403 to move, to achieve the tool 407 on the outer wall of the pipe processing at different positions; S06. The first spring 302 automatically adjusts the position of the sliding frame 304 and the lifting frame 303 to achieve horizontal sliding and uniform support of the pipe; S07. After the processing is completed, the second motor 417 drives the clamping wheel 419 to rotate, and the pipe is transported out of the machine tool body 1, completing the unloading operation.

[0032] This processing method utilizes the first pneumatic chuck and the second pneumatic chuck of the above-mentioned precision pipe processing device to firmly clamp the two ends of the pipe respectively. During the processing, the fifth motor drives the sleeve to rotate, driving the pipe to rotate, so as to realize the processing of the outer wall of the pipe. When the positioning seat moves, the first spring automatically adjusts the position of the sliding frame and the lifting frame to ensure that the sliding frame and the lifting frame are evenly distributed at different positions of the pipe. The support block and support rod on the top of the lifting frame are used to evenly support the bottom of the pipe to prevent the pipe from bending downward due to its own weight, thereby improving the processing accuracy.
