However, for some special application scenarios, such as medical equipment, spacecraft, precision instruments, etc., magnetic materials may have a negative impact on the performance and accuracy of the equipment. Therefore, it is necessary to develop a non-magnetic planetary speed reducer.

[0003] During the operation of the planetary speed reducer equipment on the market at present, vibration will inevitably occur, and instantaneous impact force will also be generated, such as the inertial force at the moment of startup, sudden change of load, etc. If these vibrations and impact forces are not controlled, they will have an adverse impact on the accuracy and stability of the subsequent speed reducer, and will also shorten the service life of the speed reducer. Summary of the Utility Model

[0005] To achieve the above purpose, the utility model provides the following technical solution: a non-magnetic planetary speed reducer, including a placement plate, two screw plates are fixedly connected to the surface of the placement plate, a speed reducer body is arranged between the two screw plates, and two clamping mechanisms are arranged between the speed reducer body and the screw plates. A bottom plate is arranged at the bottom of the placement plate, and a plurality of buffer mechanisms are arranged between the placement plate and the bottom plate;

[0006] Each buffer structure includes a buffer cylinder fixedly connected to the bottom plate and a connecting column fixedly connected to the bottom of the placement plate. A sliding cover is slidably arranged on the inner wall of the buffer cylinder, a sliding column is inserted on the surface of the sliding cover, a first spring is movably sleeved on the surface of the sliding column, and the top and bottom of the first spring are respectively fixedly connected to the bottom of the sliding cover and the top of the bottom plate. A plurality of micro air vents are arranged on the surface of the buffer cylinder;

[0007] The connecting column is fixedly connected to the sliding cover, an insertion port is arranged at the bottom of the connecting column, and the insertion port is adapted to the sliding column.

[0008] Preferably, each clamping mechanism includes a screw hole arranged on the surface of the screw plate, a rotating screw is threadedly connected inside the screw hole, and one end of the rotating screw is rotatably connected to a clamping plate, so as to move the clamping plate and further be able to clamp the speed reducer body.

[0009] In order for the clamping plate to move smoothly to the surface of the reducer body, preferably, two guiding holes are provided on the surfaces of both of the screw plates, and a guiding rod is inserted at the bottom of each guiding hole. One end of the guiding rod close to the reducer body is fixedly connected to the clamping plate.

[0010] In order to facilitate the loosening of the clamping plate, preferably, a blocking disk is provided at one end of the guiding rod away from the reducer body, and the blocking disk is slidably connected to the inner wall of the guiding hole.

[0016] The technical effects and advantages of the present utility model:

[0017] 1. By providing a buffer mechanism, compared with the prior art, when the reducer body is working, an impact force will be generated. At this time, the generated impact force is transmitted to the connecting column through the bottom plate. The connecting column pushes the sliding cover to move down or up. At this time, the air pressure inside the buffer cylinder changes, and the first spring is also compressed or stretched, so that the impact force generated by the reducer body is released. During the release of the impact force, the micro-venting port can prevent the air pressure from changing too much and damaging the buffer mechanism. Through the above operations, the accuracy and stability of the reducer can be ensured, and the service life of the reducer can be extended.

[0018] 2. By providing a clamping mechanism, compared with the prior art, when it is necessary to fix the position of the reducer body, by rotating two turntables forward, the rotating screw rod rotates inside the screw hole, and the rotating screw rod moves in the direction close to the reducer body, thereby driving the two clamping plates to move. At this time, the guiding rod is also driven to assist the movement of the clamping plate. At the same time, the blocking disk moves to compress the second spring. Through the above operations, the position of the reducer body is fixed;

[0019] When it is necessary to release the fixation, reverse the two turntables so that the rotating screw drives the two clamping plates to move away from the reducer body. At this time, the second spring resets and drives the guide rod, which can assist the movement of the clamping mechanism, thus more easily releasing the fixation.

[0020] 3. By setting the material of the reducer body, compared with the prior art, since the reducer body and its internal components are all made of non-magnetic materials, this device can be applied to some special application scenarios, such as medical equipment, spacecraft, precision instruments, etc. Brief Description of the Drawings

Detailed Embodiment

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0029] As shown in the attached Figures 1 - 6A non-magnetic planetary reducer as shown includes a placement plate 1. Two screw plates 2 are fixedly connected to the surface of the placement plate 1. A reducer body 4 is arranged between the two screw plates 2, and two clamping mechanisms are arranged between the reducer body 4 and the screw plates 2. A bottom plate 3 is arranged at the bottom of the placement plate 1, and a plurality of buffer mechanisms are arranged between the placement plate 1 and the bottom plate 3;

[0030] Each buffer structure includes a buffer cylinder 5 fixedly connected to the bottom plate 3 and a connecting column 6 fixedly connected to the bottom of the placement plate 1. A sliding cover 7 is slidably arranged on the inner wall of the buffer cylinder 5. A sliding column 8 is inserted on the surface of the sliding cover 7. A first spring 9 is movably sleeved on the surface of the sliding column 8. The top and bottom of the first spring 9 are respectively fixedly connected to the bottom of the sliding cover 7 and the top of the bottom plate 3. A plurality of micro air vents 10 are arranged on the surface of the buffer cylinder 5;

[0031] The connecting column 6 is fixedly connected to the sliding cover 7. An insertion port 11 is arranged at the bottom of the connecting column 6, and the insertion port 11 is adapted to the sliding column 8;

[0032] The cross-section of the bottom plate 3 is trapezoidal, and a plurality of fixing ports 21 are arranged on the surface of the bottom plate 3.

[0033] Through the above operations, the device can be made more practical, the accuracy and stability of the reducer can be guaranteed, and the service life of the reducer can be extended.

[0034] Specifically, the device is fixed in position through the fixing ports 21 on the bottom plate 3. When the reducer body 4 is working, an impact force will be generated. At this time, the generated impact force is transmitted to the connecting column 6 through the bottom plate 3. The connecting column 6 pushes the sliding cover 7 to move down or up. At this time, the air pressure inside the buffer cylinder 5 changes, and the first spring 9 is also compressed or stretched, so that the impact force generated by the reducer body 4 is released. During the release of the impact force, the micro air vents 10 can prevent the air pressure from changing too much and damaging the buffer mechanism;

[0035] Most of the impact force is buffered due to the change in air pressure inside the buffer cylinder 5, and the first spring 9 plays an auxiliary role. Therefore, the device has a buffering effect;

[0036] Because the impact force generated when the reducer is in use is small, the position change of the sliding cover 7 is not too large, so it will not affect the normal output of the reducer body 4.

[0037] In a specific embodiment, as shown in FIGS. Figure 4 、 5 、6, each clamping mechanism includes a screw hole 12 arranged on the surface of the screw plate 2. A rotating screw 13 is threadedly connected inside the screw hole 12, and one end of the rotating screw 13 is rotatably connected to a clamping plate 14;

[0038] Two of the surfaces of the screw plates 2 are each provided with two guiding holes 15. One end of each guiding rod 16 is inserted into the bottom of each guiding hole 15, and one end of the guiding rod 16 close to the speed reducer body 4 is fixedly connected to the clamping plate 14;

[0039] One end of the guiding rod 16 away from the speed reducer body 4 is provided with a blocking disk 17, and the blocking disk 17 is slidably connected to the inner wall of the guiding hole 15. A second spring 18 is movably sleeved on the surface of the guiding rod 16. One end of the second spring 18 is fixedly connected to the surface of the blocking disk 17, and the other end is fixedly connected to the inner wall of the bottom of the guiding hole 15.

[0040] Through the above operations, the fixation and release of the speed reducer body 4 can be easily achieved.

[0041] Specifically, by rotating the two turntables 20 in the forward direction, the rotating screw rod 13 rotates inside the screw hole. The rotating screw rod 13 moves in the direction close to the speed reducer body 4, thereby driving the two clamping plates 14 to move. At this time, the guiding rod 16 is also driven to assist the movement of the clamping plate 14. At the same time, the blocking disk 17 slides in the guiding hole 15, compressing the second spring 18. Through the above operations, the position of the speed reducer body 4 is fixed;

[0042] When it is necessary to release the fixation, reverse the two turntables 20, so that the rotating screw rod 13 drives the two clamping plates 14 to move away from the speed reducer body 4. At this time, the second spring 18 resets, driving the guiding rod 16, which can assist the movement of the clamping mechanism, thus easily releasing the fixation.

[0043] In a specific embodiment, as shown in the appendix Figure 4 One end of the clamping plate 14 close to the speed reducer body 4 is provided with a rubber pad 19;

[0044] One end of the rotating screw rod 13 is provided with a turntable 20;

[0045] The speed reducer body 4 and its internal components are all made of non-magnetic materials, and the surface of the speed reducer body 4 is sprayed with anti-rust paint;

[0046] The surface of the sliding cover 7 is closely attached to the inner wall of the buffer cylinder 5.

[0047] Through the above operations, the application scenarios of the device can be made wider.

[0048] Specifically, because the speed reducer body 4 and its internal components are all made of non-magnetic materials, the device can be applied to some special application scenarios, such as medical equipment, spacecraft, precision instruments, etc.

[0049] Working principle of the utility model: Place the reducer body 4 on the surface of the placement plate 1. First, fix the position of the reducer body 4. By rotating two turntables 20 forward, the rotating screw 13 rotates inside the screw hole, and the rotating screw 13 moves towards the direction close to the reducer body 4, thereby driving the movement of two clamping plates 14. At this time, the guide rod 16 is also driven to assist the movement of the clamping plate 14. At the same time, the blocking disc 17 slides in the guide hole 15, compressing the second spring 18. Through the above operations, the position of the reducer body 4 is fixed;

[0050] When the reducer body 4 is working, an impact force will be generated. At this time, the generated impact force is transmitted to the connecting column 6 through the bottom plate 3. The connecting column 6 pushes the sliding cover 7 to move down or up. At this time, the air pressure inside the buffer cylinder 5 changes, and the first spring 9 is also compressed or stretched, so that the impact force generated by the reducer body 4 is released;

[0051] During the process of releasing the impact force, the micro ventilation port 10 can prevent the air pressure from changing too much and damaging the buffer mechanism. Through the above operations, the accuracy and stability of the reducer can be ensured, and the service life of the reducer can be extended;

[0052] When it is necessary to release the fixation, reverse the two turntables 20, so that the rotating screw 13 drives the two clamping plates 14 to move away from the reducer body 4. At this time, the second spring 18 resets, driving the guide rod 16, which can assist the movement of the clamping mechanism, so as to easily release the fixation.

[0053] The above are only the preferred embodiments of the utility model and are not used to limit the utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
