[0028] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0029] Example 1

[0030] See Figures 1 to 7 In an embodiment of the present invention, a reaming device for automobile wiring harness production includes a reaming seat 1, on which a rotating cylinder 7 is rotatably mounted, and one end of the rotating cylinder 7 passes through the reaming seat 1 and is rotatably mounted with a fixed disk 20, and a plurality of fixed plates 21 are mounted on the outer wall of the fixed disk 20, and a fixing groove 24 is provided on the fixing plate 21, and a fixing block 25 is slidably mounted inside the fixing groove 24, and a connecting plate 14 is fixedly connected to the fixing block 25, and the connecting plate 14 is fixed to the outer wall of the connecting cylinder 13, and a reaming shaft 16 is rotatably mounted inside the connecting cylinder 13, and a reaming cylinder 17 is mounted on the reaming shaft 16. When reaming, a rubber waterproof ring used in the production of automobile wiring harnesses is set on the outer position of the reaming cylinder 17, and the fixed disk 2 0 is provided with a motion mechanism that drives multiple reaming cylinders 17 to move synchronously in a straight line, so that the reaming cylinders 17 can perform reaming movement along the radial direction of the inner wall of the rubber waterproof ring. The rotating cylinder 7 is installed with a gear mechanism that drives the reaming shaft 16 to rotate synchronously, so that the reaming cylinder 17 can also rotate when reaming, so that the rubber waterproof ring in the reaming state can rotate along the outer wall of the reaming cylinder 17, ultimately ensuring the 360° all-round reaming needs and further improving the reaming quality of the waterproof ring. The reaming seat 1 is also provided with an adjustment mechanism for adjusting the position of the motion mechanism, so as to adjust the position between the reaming cylinders 17 in the rotating state, and ultimately meet the need for expanding the inner diameter during reaming.

[0031] In order to ensure the rotational power requirement of the reaming cylinder 17 during reaming, in this embodiment, a motor base 2 is installed on the reaming base 1, and a reaming motor 3 is installed on the motor base 2. The output end of the reaming motor 3 is connected to a driving pulley 4, and the outer wall of the driving pulley 4 is connected to a driven pulley 26 fixed on the rotating cylinder 7 through a belt 5. When working, the reaming motor 3 is started, and then the rotating cylinder 7 is rotated under the action of the driving pulley 4 and the driven pulley 26. Finally, with the cooperation of the gear mechanism, the effective rotation of the reaming shaft 16 is realized.

[0032] In order to ensure that the linear movement distances of multiple reaming cylinders 17 along the fixed plate 21 in this embodiment are synchronized, the movement mechanism includes a limiting cylinder 23 fixed on the fixed disk 20, and a moving cylinder 18 is slidingly provided on the outer side of the limiting cylinder 23. The outer wall of the moving cylinder 18 is installed with moving plates 22 of the same number as the fixed plate 21, and a connecting rod 15 is hingedly provided between the moving plate 22 and the connecting plate 14. During operation, with the cooperation of the adjustment mechanism, the moving cylinder 18 moves along the axial direction of the limiting cylinder 23, and then with the cooperation of the moving plate 22, the connecting rod 15 drives the connecting cylinder 13 to perform synchronous linear motion under the limiting action of the fixed block 25 and the fixed groove 24.

[0033] In order to prevent the moving cylinder 18 from shaking when moving along the axial direction of the limiting cylinder 23, in a preferred case of this embodiment, a limiting strip 27 is symmetrically installed on the outer wall of the limiting cylinder 23, and a limiting groove that cooperates with the limiting strip 27 is provided on the inner wall of the moving cylinder 18. The limiting strip 27 slides linearly inside the limiting groove, thereby ultimately ensuring the implementation of the above-mentioned effect.

[0034] In one case of this embodiment, the adjustment mechanism includes an adjustment shaft 8 that is connected to the inside of the limiting cylinder 23 along the axial direction. The adjustment shaft 8 is connected to the moving cylinder 18 through the threaded area 19. By setting the threaded area 19, the rotational motion of the adjustment shaft 8 can be converted into the linear motion of the moving cylinder 18, thereby meeting the adjustment needs of the motion mechanism. The end of the adjustment shaft 8 away from the threaded area 19 passes through the rotating cylinder 7 and is connected to the worm gear 6. The outer side of the worm gear 6 is engaged with a worm 11. The worm 11 is rotatably mounted on the adjustment frame 9 through the drive shaft 10. The adjustment frame 9 is fixed on the reaming seat 1. The drive One end of the moving shaft 10 passes through the adjustment frame 9 and is connected to the handle 12. When working, the handle 12 is rotated so that the handle 12 drives the driving shaft 10 to rotate, and then the adjusting shaft 8 is synchronized by the engagement between the worm 11 and the worm wheel 6. Then, with the cooperation of the threaded area 19, the effective movement of the moving cylinder 18 is ensured. Since the worm 11 and the worm wheel 6 are engaged in the above-mentioned torque transmission process in this embodiment, and the above-mentioned transmission pair has self-locking performance, the angle of the adjusting shaft 8 after rotation can be maintained, thereby further improving the reliability of the adjustment mechanism.

[0035] In one case of this embodiment, the gear mechanism includes a central gear 32 fixed on the rotating cylinder 7, a transmission gear 31 is meshed on the outer side of the central gear 32, and a moving gear 30 is meshed on the outer side of the transmission gear 31. A limit frame 29 is coaxially installed between the moving gear 30 and the transmission gear 31, and a limit plate 28 is rotatably installed on the rotating cylinder 7. The outer side of the limit plate 28 is hingedly set at the connection position between the limit frame 29 and the transmission gear 31. The reaming shaft 16 passes through the fixed slot 24 and is fixedly connected to the center position of the moving gear 30. During operation, the central gear 32 rotates under the drive of the rotating cylinder 7, and then the moving gear 30 rotates synchronously under the meshing action of the transmission gear 31, thereby causing the reaming shaft 16 to drive the reaming cylinder 17 to rotate synchronously. Due to the provision of the limit plate 28 and the limit frame 29, the meshing between the moving gear 30, the transmission gear 31 and the central gear 32 will not change when the position of the moving gear 30 changes, and ultimately the reaming cylinder 17 can still rotate when the position moves, further improving the reliability of the reaming device.

[0036] In order to enable the reaming tube 17 to drive the rubber waterproof ring to rotate when rotating, it is necessary to increase the friction between the reaming tube 17 and the inner wall of the waterproof ring. In this embodiment, a plurality of friction grooves are provided on the reaming tube 17.

[0037] Example 2

[0038] In another embodiment of the present invention, this embodiment differs from the above embodiment in that the fixed block 25 is a trapezoidal block structure, and the fixed groove 24 is a dovetail groove structure. By setting the fixed block 25 and the fixed groove 24 into the above structure, the fixed block 25 will not shake when moving inside the fixed groove 24 on the fixed plate 21, further ensuring the movement stability of the motion mechanism.

[0039] The working principle of the present invention is: when working, the staff only needs to put the rubber waterproof ring that needs to be expanded on the outer wall of the expansion tube 17, and then start the expansion motor 3, and continuously rotate the handle 12 at the same time, so that the distance between the expansion tubes 17 is continuously increased, and finally the rubber waterproof ring is expanded quickly and efficiently, and the whole operation process is quick and convenient.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
