[0018] 2. By pulling the pull plate, the pull plate moves the pull rod and the moving block upwards, and the limiting rod then disengages from the inside of the locking hole, releasing the limiting of the mounting block.

[0019] 3. By rotating the rotating rod, the rotating rod drives the threaded sleeve to rotate. Under the action of the external thread of the connecting column, the threaded sleeve drives the rotating rod to move axially and release the limit on the rotating wheel. At this time, the rotating wheel is rotated outside the limit shaft. When the other set of chamfering cutters reaches the appropriate angle, the rotating rod is rotated in the opposite direction. The rotating rod drives the threaded sleeve to rotate in the opposite direction and sleeve it on the outside of the other set of connecting columns, thereby fixing the rotating wheel and completing the switching of chamfering cutters.

Detailed Implementation

[0030] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding the present invention, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other. Example

[0031] Please see Figures 1-9 The present invention provides a solution: a multi-station reaming machine for processing bicycle parts, including an operating table 1, a first guide rail 2 provided at the upper end of the operating table 1, a first electromagnetic block 3 provided outside the first guide rail 2, a support plate 4 fixedly connected to the upper end of the first electromagnetic block 3, a fixing block 5 fixedly connected to the upper end of the support plate 4, a threaded hole 6 provided inside the fixing block 5, a guide hole 7 provided inside the fixing block 5 near the threaded hole 6, a guide rod 8 slidably connected inside the guide hole 7, a short block 9 fixedly connected to one end of the guide rod 8, a push ring 47 fixedly connected to one side of the short block 9, a short rod 10 provided inside the push ring 47, a stud 11 fixedly connected to the front end of the short rod 10, an arc-shaped block 12 fixedly connected to the outer side of the push ring 47, and the stud 11 being rotatably connected to the push ring 47 through the short rod 10.

[0032] Specifically, rotating the stud 11 causes the push ring 47 to move to one side due to the engagement of the external thread of the stud 11 and the internal thread of the fixing block 5. During this process, the sleeve 21 moves along with it, and the inner side of the sleeve 21 will be tightly attached to one end of the tube to be enlarged, thus fixing it and allowing the enlargement operation to begin. Similarly, rotating the stud 11 in the opposite direction causes the push ring 47 and the sleeve 21 to move in the opposite direction, releasing the restriction on the tube and making it easier to remove the tube from the sleeve 21. In addition, the guide rod 8 and the guide hole 7 further improve the stability of the sleeve 21 during movement. The position of the sleeve 21 can be adjusted by the components such as the stud 11, the fixing block 5, the guide rod 8, and the push ring 47, thereby enabling it to engage with another set to limit the tube, effectively preventing shaking and improving the quality of the enlargement. Example

[0033] Please see Figures 1-9 The present invention provides a technical solution: a multi-station reaming machine for processing bicycle parts, wherein a fixed seat 13 is fixedly connected to one side of an arc-shaped block 12, an mounting block 19 is provided inside the fixed seat 13, a through hole 20 is provided inside the mounting block 19, a sleeve 21 is provided on the rear side of the mounting block 19, an adjusting frame 14 is fixedly connected to the upper end of the fixed seat 13, a moving block 15 is provided on the inner side of the adjusting frame 14, a pull rod 16 is fixedly connected to the upper end of the moving block 15, a spring 17 is provided on the outside of the pull rod 16, a pull plate 18 is fixedly connected to the upper end of the pull rod 16, and a limit rod 46 is fixedly connected to the lower end of the moving block 15. The moving block 15 slides on the inner side of the adjusting frame 14 through the pull rod 16, the pull plate 18 and the spring 17.

[0034] Specifically, pulling the pull plate 18 causes the pull rod 16 and the moving block 15 to move upwards, while the limiting rod 46 disengages from the inside of the locking hole 20, releasing the limiting of the mounting block 19. At this time, pulling the sleeve 21 laterally causes the mounting block 19 to slide out from the inside of the fixing block 5, thus disassembling the sleeve 21. Similarly, during installation, the mounting block 19 is slid in along the inside of the fixing block 5. After it reaches the preset position, the spring 17 rebounds and pushes the moving block 15 and the pull rod 16 to move in the opposite direction. The limiting rod 46 passes through the locking hole 20 again, thus limiting the mounting block 19, thereby completing the installation of the sleeve 21. Through the components such as the pull plate 18, pull rod 16, spring 17, moving block 15, mounting block 19, and limiting rod 46, the sleeve 21 can be quickly installed and removed, allowing it to be replaced according to the specifications of the vehicle tube, while also reducing the difficulty of replacement. Example

[0035] Please see Figures 1-9This invention provides a technical solution: a multi-station reaming machine for processing bicycle parts. A first support rod 22 is fixedly connected to the upper edge of the operating table 1. A first top plate 23 is fixedly connected to the upper end of the first support rod 22. A second guide rail 24 is provided at the lower end of the first top plate 23. A second electromagnetic block 25 is provided outside the second guide rail 24. A first electric push rod 26 is provided at the lower end of the second electromagnetic block 25. A first connecting block 27 is fixedly connected to the lower end of the first electric push rod 26. A first motor 28 is provided inside the first connecting block 27. An assembly plate 29 is provided at the output end of the first motor 28. A reaming drill 30 is provided at the lower end of the assembly plate 29. A second support rod 31 is provided at the upper end of the operating table 1, away from the first support rod 22. A second top plate 32 is fixedly connected to the upper end of the second support rod 31. A third guide rail 33 is provided at the lower end of plate 32. A third electromagnetic block 34 is provided outside the third guide rail 33. A second electric push rod 35 is provided at the lower end of the third electromagnetic block 34. A second connecting block 36 is fixedly connected to the lower end of the second electric push rod 35. A second motor 37 is provided inside the second connecting block 36. A connecting frame 38 is provided at the output end of the second motor 37. A rotating rod 39 is provided on the inner wall of the connecting frame 38. A threaded sleeve 40 is fixedly connected to one end of the rotating rod 39. A limit shaft 41 is provided on the inner side of the connecting frame 38. A rotating wheel 42 is provided outside the limit shaft 41. A fixing ring 43 is fixedly connected to the outside of the rotating wheel 42. A connecting post 44 is fixedly connected to one side of the fixing ring 43. A chamfering knife 45 is fixedly connected to the outside of the rotating wheel 42 near the fixing ring 43. The external thread of the connecting post 44 is compatible with the internal thread of the threaded sleeve 40.

[0036] Specifically, rotating the rotating rod 39 causes the threaded sleeve 40 to rotate. Under the action of the external thread of the connecting column 44, the threaded sleeve 40 drives the rotating rod 39 to move axially and releases the limit on the rotating wheel 42. At this time, rotating the rotating wheel 42 rotates outside the limit shaft 41. When the other set of chamfering cutters 45 reaches the appropriate angle, rotating the rotating rod 39 in the opposite direction causes the threaded sleeve 40 to rotate in the opposite direction and fit onto the outside of the other set of connecting columns 44, thereby fixing the rotating wheel 42 and completing the switching of the chamfering cutters 45. Through components such as the rotating rod 39, threaded sleeve 40, connecting column 44, and rotating wheel 42, different specifications of chamfering cutters 45 can be flexibly switched, thereby meeting diverse deburring needs. At the same time, multiple chamfering cutters 45 are integrated on the rotating wheel 42, and there is no need to disassemble the whole machine when switching, reducing downtime, effectively improving processing efficiency, and bringing great convenience to production operations.

[0037] Working Principle: When using this reaming machine, firstly, the end of the pipe to be reamed is inserted into the sleeve 21 and fixed. Specifically, rotating the stud 11 causes the push ring 47 to move to one side due to the engagement of the external thread of the stud 11 and the internal thread of the fixing block 5. During this process, the sleeve 21 moves along with it, and the inner side of the sleeve 21 will tightly adhere to one end of the pipe to be reamed, thus fixing it and allowing the reaming operation to begin. Similarly, rotating the stud 11 in the opposite direction causes the push ring 47 and sleeve 21 to move in the opposite direction, releasing the reaming operation. The limiting of the tube facilitates its removal from the tube sleeve 21. Furthermore, the guide rod 8 and guide hole 7 further enhance the stability of the tube sleeve 21 during movement. The position of the tube sleeve 21 can be adjusted using components such as the stud 11, fixing block 5, guide rod 8, and push ring 47, allowing it to cooperate with another set to limit the tube's movement, effectively preventing wobbling and improving the quality of the enlarged hole. After fixing, the first solenoid valve is activated, moving the support plate 4 and the tube to the lower end of the first top plate 23. Next, the first electric push rod 26 pushes the first connecting block 27 downwards. With the cooperation of the first motor 28, the reaming drill 30 rotates and penetrates the tube to enlarge the hole. After enlargement, the first solenoid block 3 continues to move to the second top plate 32. Subsequently, under the action of the second electric push rod 35 and the second motor 37, the chamfering cutter 45 enters the enlarged hole position of the tube to remove burrs.After cleaning, the first electromagnetic block 3 delivers the vehicle pipe to the right side of the operating table 1, where the worker removes it, completing the entire reaming process. This device is equipped with a fixed station, a reaming station, and a deburring station. Each station has a clear division of labor and works in close coordination. The fixed station ensures the stability of the vehicle pipe, the reaming station precisely completes the reaming operation, and the deburring station promptly removes burrs. The three work together to effectively improve the overall efficiency of vehicle pipe reaming. When different specifications of chamfering cutters 45 are needed and need to be switched, the rotating rod 39 is rotated. The rotating rod 39 drives the threaded sleeve 40 to rotate, and under the action of the external thread of the connecting column 44... The threaded sleeve 40 drives the rotating rod 39 to move axially and releases the limit on the rotating wheel 42. At this time, the rotating wheel 42 rotates outside the limit shaft 41. When the other set of chamfering blades 45 reaches the appropriate angle, the rotating rod 39 is rotated in the opposite direction. The rotating rod 39 drives the threaded sleeve 40 to rotate in the opposite direction and fits onto the outside of the other set of connecting posts 44, thereby fixing the rotating wheel 42 and completing the switching of the chamfering blades 45. Through the rotating rod 39, threaded sleeve 40, connecting posts 44, rotating wheel 42 and other components, different specifications of chamfering blades 45 can be flexibly switched, thus meeting diverse deburring needs. To meet the demand for piercing, multiple chamfering cutters 45 are integrated on the rotary wheel 42, eliminating the need for complete disassembly during switching, reducing downtime, effectively improving processing efficiency, and bringing great convenience to production operations. In addition, different machined pipes can be fixed by replacing the sleeve 21. Specifically, pulling the pull plate 18 causes the pull rod 16 and the moving block 15 to move upward, while the limiting rod 46 disengages from the inside of the locking hole 20, releasing the limitation on the mounting block 19. At this time, pulling the sleeve 21 laterally causes the mounting block 19 to slide out of the inside of the fixing block 5. To remove the sleeve 21, the mounting block 19 is slid into the inner side of the fixing block 5. Once it reaches the preset position, the spring 17 rebounds and pushes the moving block 15 and the pull rod 16 to move in the opposite direction. The limiting rod 46 passes through the locking hole 20 again to limit the mounting block 19, thus completing the installation of the sleeve 21. The sleeve 21 can be quickly installed and removed by components such as the pull plate 18, pull rod 16, spring 17, moving block 15, mounting block 19, and limiting rod 46, which can be replaced according to the specifications of the vehicle tube and reduce the difficulty of replacement.

For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and these variations still fall within the protection scope of the present invention.
