Description

Technical Field

[0001] The utility model relates to the technical field of pipe fitting processing, in particular to a pipe fitting end face boring processing device. Background Technique

[0002] When processing pipe fittings, boring processing can further enlarge the aperture of the end face of the pipe fitting to meet specific dimensional requirements. At the same time, through boring processing, the required aperture dimensional tolerance and surface roughness can be obtained, and the surface quality of the end face of the pipe fitting can be improved.

[0003] After retrieval, a patent document with the publication number of CN220497849U discloses a pipe fitting end face boring processing device. The processing device sequentially loads the pipe fittings to be processed onto the loading plate. When the pipe fitting at the lowest layer falls onto the lower clamping plate, the positioning cylinder drives the lower clamping plate to approach the upper clamping plate to stably clamp the pipe fitting. The processing driving cylinder can drive the moving table to reciprocate along the linear guide rail. The main shaft motor drives the composite cutter head to rotate. As the moving table gradually approaches the pipe fitting until the composite cutter head contacts the end face of the pipe fitting, the boring processing can be completed. The processing driving cylinder can drive the moving table to return to its original position, and the positioning cylinder drives the lower clamping plate to move down to release the pipe fitting.

[0004] However, the above-mentioned processing device has certain defects when in use:

[0005] Since the position of the main shaft motor is fixed, the boring position of the boring tool is fixed, and at the same time, the specification of the boring tool is determined, so it cannot effectively perform boring processing on pipe fittings with various inner diameter specifications, reducing the operation effect of the processing device and making the boring work have certain limitations.

The lower end of the material guiding frame 4 is fixedly provided with a receiving plate 5. The upper end of the side wall of the receiving plate 5 is fixedly provided with a mounting plate 6. The top of the mounting plate 6 is fixedly provided with a second electric cylinder 7. The top of the second electric cylinder 7 is fixedly provided with a pressing plate 8. The top of the inner wall of the pressing plate 8 is fixedly provided with a side plate 17. The side plate 17 is used for supporting when boring the pipe fitting. The second electric cylinder 7 can drive the pressing plate 8 and the side plate 17 to press the top of the pipe fitting to prevent the pipe from shifting during processing;

[0025] The top of the frame 1 is fixedly provided with a baffle 9. The outer wall of the baffle 9 is fixedly provided with a third electric cylinder 10. The end of the output shaft of the third electric cylinder 10 is fixedly provided with a mobile frame 11. The outer wall of the mobile frame 11 is fixedly provided with a drive motor 12. The mobile frame 11 can move, so that the boring tool assembly can contact and extend into the pipe fitting for boring. The bottom of the inner wall of the mobile frame 11 is fixedly provided with a vertical plate 13. The upper end of the vertical plate 13 is rotatably penetrated by a rotating rod 14. The rod wall of the rotating rod 14 is fixedly sleeved with a rotating plate 15. A plurality of mounting holes arranged in a circumferentially symmetric manner are opened inside the rotating plate 15. A plurality of boring tool assemblies 16 are rotatably penetrated in the plurality of mounting holes. The specifications of the plurality of boring tool assemblies 16 are different. The rotating plate 15 can be rotated according to the inner diameter specification of the pipe fitting to switch different specifications of the boring tool assemblies 16, improving the boring range;

[0026] A connecting drive mechanism is provided between the drive motor 12 and the boring tool assembly 16. The connecting drive mechanism includes a sleeve 18 which is slidably sleeved outside the output shaft of the drive motor 12. A positioning rod 19 is fixedly provided at the end of the sleeve 18. A positioning groove 20 for the positioning rod 19 to be inserted is provided on the side wall of the boring tool assembly 16. The longitudinal cross-sections of the positioning rod 19 and the positioning groove 20 are both hexagonal. A first spring 21 is sleeved outside the output shaft of the drive motor 12. The two ends of the first spring 21 are respectively fixedly connected to the sleeve 18 and the output shaft of the drive motor 12. The insertion fit between the positioning rod 19 and the positioning groove 20 enables the drive motor 12 to be quickly connected to a variety of boring tool assemblies 16;

[0027] A limiting hole is provided on the tube wall of the sleeve 18. A limiting rod 22 is fixedly provided on the outer wall of the output shaft of the drive motor 12. The limiting rod 22 slides in the limiting hole, enabling the positioning rod 19 to rotate stably when the output shaft of the drive motor 12 rotates;

[0028] A connecting plate 23 is fixedly provided on the rod wall of the rotating rod 14. A plug rod 24 slides through the inside of the connecting plate 23. A second spring 25 is sleeved on the rod wall of the plug rod 24. The two ends of the second spring 25 are respectively fixedly connected to the plug rod 24 and the connecting plate 23. A plurality of jacks 26 arranged in a circumferentially symmetric manner are provided at the upper end of the vertical plate 13. The end of the plug rod 24 is inserted into the jack 26. The insertion of the plug rod 24 into different positions of the jacks 26 can fix the position of the boring tool assembly 16 after it is transposed.

[0029] In summary: Before boring the pipe fitting, determine the inner diameter specification of the pipe fitting, and pull the plug rod 24, so that the second spring 25 is stretched. At this time, the plug rod 24 is separated from the jack 26, and the rotating plate 15 can be rotated under the support of the rotating rod 14 to transpose a plurality of boring tool assemblies 16 with different specifications. When the boring tool assembly 16 is selected, release the plug rod 24, and under the elastic recovery of the second spring 25, the plug rod 24 is inserted into the jack 26 to complete the position fixing of the boring tool assembly 16;

[0030] Subsequently, start the first electric cylinder 3 to adjust the longitudinal setting height of the material guiding frame 4, and place the pipe fitting in the material guiding frame 4, so that the pipe fitting slides down stably and moves onto the receiving plate 5. At this time, the pipe fitting and the boring tool assembly 16 are on the same horizontal line. Then start the second electric cylinder 7 to make the pressing plate 8 press the side plate 17 downward to tightly press and support the pipe fitting from the side;

[0031] Before the boring tool assembly 16 rotates and transposes, the sleeve 18 can be moved so that the sleeve 18 can be inserted into the positioning groove 20 at the end of the boring tool assembly 16. Thus, after the pipe fitting is clamped, start the drive motor 12 to make the boring tool assembly 16 rotate. Subsequently, start the third electric cylinder 10, and the moving frame 11 moves on the machine frame 1, enabling the boring tool assembly 16 to contact the pipe fitting and start boring processing.
