[0002] Planetary gear reducers, also known as planetary speed reducers, have many advantages such as small size, high transmission efficiency, wide deceleration range, and high precision. They are widely used in transmission systems such as servo motors, stepper motors, and DC motors. When assembled, planetary gear reducers are usually placed directly on a support table or desktop. Not only is it difficult to adjust the placement height, but if the placement position is relatively biased, it is also very easy to affect the overall stability of the support structure. At the same time, during the assembly process, workers often have to walk around the planetary gear reducer to find a suitable assembly angle for the planetary gear reducer. Therefore, there is an urgent need for a support structure for the assembly of planetary gear reducers. Utility Model Content

[0029] It also contains:

[0030] There are two bidirectional screws 4, which are rotatably arranged on the upper and lower sides of the support platform 3 through bearings. Two No. 1 motors 5 are fixedly arranged in the support platform 3, and the output shafts of the No. 1 motors 5 are connected to the bidirectional screws 4;

[0031] Sliders 6, there are four of them, which are respectively sleeved on two bidirectional screws 4 by threaded rotation. The slides 6 are slidably set in the slide grooves 14 opened on the support platform 3. The clamping blocks 7 are fixedly set on the slides 6. The slide grooves 14 are fixedly provided with an accordion cover 13 connected to the slides 6. The accordion cover 13 can provide protection for the slide grooves 14 to prevent debris from falling into the slide grooves 14 and affecting the sliding of the slides 6;

[0032] The support base 8 is provided below the connecting base 1. The support base 8 and the connecting base 1 are connected by a lifting mechanism 9. The connecting frame 2 is provided with a limiting mechanism 10 connected to the support platform 3.

[0033] The lifting mechanism 9 comprises:

[0034] No. 2 motor 9-1, said No. 2 motor 9-1 is fixedly arranged in the connecting seat 1, and a No. 1 gear 9-2 is fixedly sleeved on the output shaft of the No. 2 motor 9-1;

[0035] Support rods 9-3, there are several support rods 9-3, with equal fillets distributed on the upper part of the support seat 8, a threaded rod 9-4 is inserted into the support rod 9-3 by thread rotation, and the upper end of the threaded rod 9-4 is inserted into the connecting seat 1 by rotation through a bearing;

[0036] The second gear 9-5 is a plurality of the second gears 9-5, which are fixedly sleeved on the plurality of threaded rods 9-4 respectively, and the first gear 9-2 is meshed with the plurality of second gears 9-5;

[0037] The limiting mechanism 10 includes:

[0038] There are two movable rods 10-1, which are movably arranged on the front and rear sides of the connecting frame 2. A spring 10-2 connected to the movable rod 10-1 is fixedly arranged in the connecting frame 2. One end of the movable rod 10-1 passes through the connecting frame 2 and is fixedly provided with a pulling handle 10-3;

[0039] The third gear 10-4 is rotatably arranged in the connecting frame 2 via a shaft and a bearing. A rack 10-5 meshing with the third gear 10-4 is fixedly arranged on the side wall of the movable rod 10-1;

[0040] There are two limit blocks 10-6, which are fixed on the two pulling handles 10-3 respectively. The lower edge of the support platform 3 is distributed with several slots 11 that match the limit blocks 10-6. The opening of the slot 11 is provided with a chamfer 12, which can provide guidance when the limit block 10-6 is clamped into the slot 11.

[0041] When using the present invention, the planetary gear reducer is placed on the support platform 3, and then the No. 1 motor 5 is started. The No. 1 motor 5 drives the bidirectional screw 4 to rotate, so that the slider 6 can drive the clamping block 7 to move to the middle of the upper part of the support platform 3, thereby realizing the center clamping limit of the planetary gear reducer on the support platform 3. When it is necessary to adjust the height of the planetary gear reducer, the No. 2 motor 9-1 can be started, and the No. 2 motor 9-1 drives the No. 1 gear 9-2 to rotate. The No. 1 gear 9-2 drives several No. 2 gears 9-5 to rotate synchronously. The No. 2 gear 9-5 drives the threaded rod 9-4 to rotate, and adjusts the distance between the connecting seat 1 and the support seat 8, thereby realizing the adjustment of the height of the planetary gear reducer. When it is necessary to adjust the angle of the planetary gear reducer toward the staff, the pull handle 10-3 can be moved away from the connecting frame 2 , and the gear 10-3 is pulled in the direction of rotation. The pulling handle 10-3 drives the movable rod 10-1 and the limit block 10-6 to move, and the rack 10-5 is engaged with the third gear 10-4, so that the pulling handles 10-3 on both sides move synchronously in the opposite direction with the movable rod 10-1. At this time, the spring 10-2 is compressed, and the limit block 10-6 is moved out of the slot 11, and then the support platform 3 can be rotated. The support platform 3 drives the planetary gear reducer to rotate, so as to adjust the angle of the planetary gear reducer toward the staff, and then the pulling handle 10-3 is released. At this time, the spring 10-2 resets and extends to push the movable rod 10-1 to move, and the movable rod 10-1 drives the pulling handle 10-3 to move toward the connecting frame 2. The pulling handle 10-3 drives the limit block 10-6 to be clamped in the slot 11 at the corresponding position to limit the rotation of the support platform 3.

[0042] Compared with the prior art, the beneficial effects of the present invention are:

[0043] Through the cooperation of the bidirectional lead screw 4, the No. 1 motor 5, the slider 6 and the clamping block 7, the planetary gear reducer placed on the support platform 3 can be clamped in the center, thereby preventing the placement position of the planetary gear reducer on the support platform 3 from being offset, which would affect the stability of the support for the planetary gear reducer;

[0044] Through the cooperation of the lifting mechanism 9 and the limiting mechanism 10, the assembly height and angle of the planetary gear reducer can be adjusted, thereby improving the convenience of the planetary gear reducer assembly process.

[0045] For those skilled in the art, they can modify the technical solutions described in the aforementioned embodiments and make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the scope of protection of the present utility model.
