DETAILED DESCRIPTION

[0021] The following is combined with Figure 1-4 This application is described in further detail.

[0022] The embodiment of the present application discloses a rotary adjustment device.

[0023] Reference Figure 1 and Figure 2The rotary adjustment device includes a mounting frame 1, a vertically arranged screw rod 2 is rotatably connected to the mounting frame 1, and the mounting frame 1 and the screw rod 2 are rotatably connected by a bearing. In the embodiment of the present application, a ball bearing is specifically used. While the bearing supports the screw rod 2, rolling friction replaces sliding friction, significantly reducing the friction coefficient between the mounting frame 1 and the screw rod 2, thereby reducing the driving force required by the debugging personnel during the adjustment process. The outer edge of the screw rod 2 is threadedly connected to a nut 3 that matches the size of the screw rod 2. The mounting frame 1 is rotatably connected to a transmission rod 4 that is vertically arranged with the screw rod 2. One end of the screw rod 2 is connected to the transmission rod 4 through a transmission unit. The mounting frame 1 is provided with a rotary adjustment unit for driving the transmission rod 4 to rotate. The mounting frame 1 and the transmission rod 4 are rotatably connected by a bushing. In the embodiment of the present application, the bushing is specifically made of copper material. The main function of the bushing is to support the transmission rod 4. Through the guiding effect of the bushing, the transmission rod 4 can maintain the correct rotation path, reducing the friction between the transmission rod 4 and the mounting frame 1, thereby reducing energy loss and wear.

[0024] Therefore, the rotation adjustment unit is started, and the rotation adjustment unit drives the transmission rod 4 to rotate, and the transmission rod 4 drives the screw rod 2 to rotate through the transmission unit. The rotation of the screw rod 2 drives the nut 3 on the screw rod 2 to move synchronously along the direction of the screw rod 2, thereby realizing the adjustment of the position of the nut 3, thereby facilitating the fine-tuning of the position of the mechanical equipment connected to the nut 3. Since the screw rod 2 and the transmission rod 4 are arranged vertically, the operating space occupied by the overall rotation adjustment device in the vertical direction is saved, and at the same time, the convenience of the debugging personnel in adjusting the position of the nut 3 is improved, so that the debugging personnel can focus more on the debugging of the equipment, reduce the workload of the debugging personnel when the mechanical equipment needs to fine-tune the limit, and improve the adjustment efficiency.

[0025] Reference Figure 1 and Figure 2 The transmission unit includes a first bevel gear 5 disposed on the end of the transmission rod 4 facing the screw rod 2. A second bevel gear 6 matching the size of the first bevel gear 5 is disposed on the end of the screw rod 2 facing the transmission rod 4. The first bevel gear 5 and the second bevel gear 6 are meshed with each other. Therefore, the rotation of the transmission rod 4 drives the first bevel gear 5 to rotate. Since the first bevel gear 5 and the second bevel gear 6 are meshed with each other, the rotation of the first bevel gear 5 drives the second bevel gear 6 to rotate, and the rotation of the second gear teeth drives the screw rod 2 to rotate. Due to the structural characteristics of the bevel gears, the transmitted power can be fully distributed across the contact area of ​​the tooth surfaces, thereby achieving high-precision transmission. This high-precision transmission helps to ensure the stability and accuracy of the rotation of the screw rod 2.

[0026] Reference Figure 2 and Figure 3The adjustment unit includes a gear seat 7 bolted to the mounting frame 1, the outer edge of the gear seat 7 is fixedly connected to the first gear ring 23, and the end of the transmission rod 4 facing away from the screw rod 2 is provided with an adjustment sleeve 8, the rotating sleeve passes through the gear seat 7 and is rotatably connected to the gear seat 7, the outer edge of the adjustment sleeve 8 is fixedly connected to the second gear ring 9, the outer edge of the rotating sleeve is rotatably connected to the adjustment ring 10, and the outer edge of the adjustment ring 10 is fixedly connected to a plurality of anti-slip ridges 17. In the embodiment of the present application, the plurality of anti-slip ridges 17 are arranged in a plum blossom shape along the outer edge of the adjustment ring 10, thereby facilitating the stability of the adjustment ring 10 gripped by the debugging personnel during the adjustment process, and the inner edge of the adjustment ring 10 is fixedly connected to a plurality of adjustment teeth 11 that match the first gear ring 23 and the second gear ring 9.

[0027] Therefore, when the position of the nut 3 needs to be adjusted, the adjusting ring 10 is rotated to drive the adjusting tooth 11 to rotate; when the adjusting tooth 11 is only engaged with the second ring gear 9, the adjusting tooth 11 rotates to drive the second ring gear 9 to rotate synchronously. At this time, the transmission rod 4 is in an adjustable state, so that the second ring gear 9 drives the transmission rod 4 to rotate, and the transmission rod 4 drives the screw rod 2 to rotate, thereby adjusting the position of the nut 3; when the adjusting tooth 11 is engaged with both the first ring gear 23 and the second ring gear 9, since the gear seat 7 is bolted to the mounting frame 1, the position of the first ring gear 23 is fixed, so that the positions of the second ring gear 9 and the adjusting tooth 11 are both fixed, and the transmission rod 4 is in a locked state.

[0028] Reference Figure 2 and Figure 3 The outer edge of the transmission rod 4 is fixedly provided with a connecting key 20, and the inner edge of the rotary sleeve 8 is provided with a connecting groove that matches the size of the connecting key 20. The connecting key 20 is inserted into the connecting groove to achieve circumferential fixation, so that the rotary sleeve 8 can realize the rotation of the transmission rod 4 through the connecting key 20 during the rotation process, thereby realizing force transmission. The outer edge of the transmission rod 4 is fixedly provided with a rotating ring 21, and the outer edge of the transmission rod 4 is sleeved with a backing ring 22. The backing ring 22 is located between the rotating ring 21 and the gear seat 7, and the backing ring 22 contacts the rotating ring 21 and the gear seat 7 respectively. The backing ring 22 can play a buffering role, preventing direct contact between the gear seat 7 and the rotating ring 21, thereby reducing wear between the gear seat 7 and the rotating ring 21.

[0029] Reference Figure 3 and Figure 4The inner edge of the adjustment ring 10 is fixedly connected to the limiting tooth 12, and the outer edge of the adjustment sleeve 8 is fixedly connected to the stopper 13 arranged perpendicularly to the limiting tooth 12. The outer edge of the adjustment sleeve 8 is respectively provided with a first limit block 14, a second limit block 15 and a third limit block 16 which are all arranged parallel to the limiting tooth 12. The third limit block 16 is located between the first limit block 14 and the second limit block 15, and the stopper 13 is located between the third limit block 16 and the first gear ring 23. Therefore, when the limit tooth 12 is located between the first limit block 14, the third limit block 16 and the stop block 13, the rotary adjustment tooth 11 is only engaged with the second ring gear 9, and the transmission rod 4 is in an adjustable state; when the limit tooth 12 is located between the second limit block 15, the third limit block 16 and the stop block 13, the rotary adjustment tooth 11 is engaged with both the first ring gear 23 and the second ring gear 9, and the transmission rod 4 is in a locked state; by controlling the position of the limit tooth 12, the workload of the debugging personnel is greatly reduced when the mechanical equipment needs to fine-tune the limit, and the switching operation between the locked state and the adjustable state is simple, so that the debugging personnel can focus more on debugging the mechanical equipment.

[0030] Reference Figure 2 and Figure 3 The outer edge of the adjustment sleeve 8 is sheathed with a compression spring 18, and a blocking block 19 is installed on the end of the adjustment sleeve 8 facing away from the transmission rod 4. The compression spring 18 is located between the blocking block 19 and the adjustment tooth 11. The blocking block 19 limits the position of the compression spring 18, reducing the possibility of the compression spring 18 escaping from the outer edge of the adjustment sleeve 8. When the debugger adjusts, he pulls up the adjustment ring 10 so that the adjustment tooth 11 only engages with the second gear ring 9, and the compression spring 18 is in a compressed state. When the debugger lets go, the compression spring 18 re-locks under the elastic action of the compression spring 18, saving time and effort while improving the installation efficiency and reliability of the adjustment device.

[0031] When the cam 11 is in engagement with the first gear 23 and the second gear 23, the cam 11 is in engagement with the first gear 23 and the second gear 23, and the cam 11 is in engagement with the first gear 23 and the second gear 23, the cam 11 is in engagement with the first gear 23 and the second gear 23, and the cam 11 is in engagement with the first gear 23 and the second gear 23, and the cam 11 is in engagement with the first gear 23 and the second gear 23, and the cam 11 is in engagement with the first gear 23 and the second gear 23, and the cam 11 is in engagement with the first gear 23 and the second gear 23.

[0032] Since the screw rod 2 and the transmission rod 4 are arranged vertically, the operating space occupied by the overall rotary adjustment device in the vertical direction is saved, and at the same time, the convenience of operation when the debugger adjusts the position of the nut 3 is improved, which saves time and effort, allows the debugger to focus more on the debugging of the equipment, reduces the workload of the debugger when the mechanical equipment needs to fine-tune the limit, and improves the adjustment efficiency. In addition, the rotary adjustment device in the embodiment of the present application can be applied to the hard limit adjustment mechanism of medium-sized mechanical devices, so that the debugger can adjust the limit and lock the limit conveniently.

[0033] This specific embodiment is merely an explanation of the present invention and is not intended to limit the present invention. After reading this specification, those skilled in the art may make non-creative modifications to this embodiment as needed. However, as long as such modifications are within the scope of the claims of the present invention, they are protected by patent law.
