[0022] In one embodiment of the present invention:
[0023] like Figure 1 and Figure 2 As shown, the bottom limit assembly 2 includes: a base 201, the base 201 is connected to the reduction box body 1; at least two brackets 202, the bracket 202 is fixedly connected to the base 201; a limit groove 203, the limit groove 203 is arranged inside the bracket 202; a fixed seat 204, the fixed seat 204 is fixedly connected to the reduction box body 1 and is connected to one end of the bracket 202 away from the base 201; at least two cross positioning grooves 205, the cross positioning groove 205 is arranged inside the fixed seat 204;
[0024] The base 201 is fixedly connected to the installation area on one side away from the reduction box body 1, and the outside of the reduction box body 1 is fixed by a fixing seat 204. Then, driven by the transmission components 5 on both sides, the linkage positioning components 4 on both sides can be driven to move in opposite directions, and cooperate with the cross positioning groove 205 to complete the secondary fixation of the fixing seat 204. At the same time, the shaft limit component 6 is set on the outside of the shaft of the reduction box body 1 to further improve the rotation stability of the shaft of the reduction box body 1.
[0025] In one embodiment of the present invention:
[0026] like Figure 1 As shown, the linkage positioning assembly 4 includes: at least two slides 401, the slides 401 are slidably connected to the base 201; an inclined frame 402, the inclined frame 402 is fixedly connected to the slide 401; a positioning frame 403, the positioning frame 403 is fixedly connected to the slide 401; an elastic member 404, one end of the elastic member 404 is fixedly connected to the bracket 202, and the other end is fixedly connected to the slide 401; the elastic member 404 is an elastic telescopic rod;
[0027] When the transmission assembly 5 moves downward, it can drive the slides 401 on both sides to move toward each other. The positioning frame 403 adopts a cross-shaped setting that matches the cross positioning groove 205. When the slides 401 on both sides move toward each other, it can drive the positioning frames 403 on both sides to insert into the cross positioning groove 205 on the corresponding side to complete the limiting of the fixed seat 204.
[0028] In one embodiment of the present invention:
[0029] like Figure 1 and Figure 3As shown, the transmission assembly 5 includes: at least two groups of driving members 504, the driving members 504 are fixedly connected to the base 201; the driving members 504 are selected from electric telescopic rods; a sleeve frame 501, the sleeve frame 501 is fixedly connected to one end of the driving member 504 away from the base 201; at least two transmission frames 502, the transmission frames 502 are fixedly connected to the sleeve frame 501, and abut against the inclined frame 402; at least two groups of limiting frames 503, the limiting frames 503 are fixedly connected to the sleeve frame 501, and are slidably connected to the limiting groove 203;
[0030] Driven by the driving members 504 on both sides, the sleeve frame 501 can be driven to move downward longitudinally. When the sleeve frame 501 moves downward, the limiting frame 503 slides along the inner side of the limiting groove 203, further improving the movement stability of the sleeve frame 501. The transmission frames 502 on both sides cooperate with the inclined frame 402 to drive the slide seats 401 on both sides to move in opposite directions.
[0031] In the present application, the driving member 504 is not limited to an electric telescopic rod, and may also be driven by a linear motor, an electric cylinder or a pneumatic cylinder, etc., as long as the longitudinal adjustment of the sleeve frame 501 can be achieved, and no specific limitation is made here.
[0032] In one embodiment of the present invention:
[0033] like Figure 1 and Figure 4 As shown, the shaft limiting assembly 6 includes: a ring frame 601, the ring frame 601 is fixedly connected to the slide seat 401 on one side; a plurality of fixed shaft frames 602, the fixed shaft frames 602 are connected to the inside of the ring frame 601; a roller 603, the roller 603 is connected to the fixed shaft frame 602 in a sleeve-type manner; at least two telescopic frames 604, one end of the telescopic frame 604 is fixedly connected to the ring frame 601, and the other end is connected to the reduction box body 1;
[0034] The interior of the ring frame 601 is hollow, and there is a groove (not shown in the figure) on the inner side of the ring frame 601 for the roller 603 to rotate. Several rollers 603 abut against the shaft body to limit the rotating shaft body. When the slide 401 moves horizontally, the ring frame 601 cooperates with the telescopic frame 604 to also move horizontally synchronously.
[0035] The working principle of the utility model is as follows: the base 201 is fixedly connected to the installation area at one side away from the reduction box body 1, and the outside of the reduction box body 1 is fixed by the fixing seat 204, and then under the drive of the transmission components 5 on both sides, the linkage positioning components 4 on both sides can be driven to move in opposite directions, and cooperate with the cross positioning groove 205 to complete the secondary fixation of the fixing seat 204. At the same time, the shaft limit component 6 is set on the outside of the shaft body of the reduction box body 1 to further improve the rotation stability of the shaft body of the reduction box body 1. When the transmission component 5 moves down, it can drive the slide seats 401 on both sides to move in opposite directions. The positioning frame 403 adopts a cross-shaped setting that matches the cross positioning groove 205.

The 504 driving member is not limited to an electric telescopic rod, and a linear motor, an electric cylinder or a cylinder drive, etc. can also be used. As long as the longitudinal adjustment of the sleeve frame 501 can be achieved, no specific limitation is made here. The interior of the ring frame 601 is hollow, and there is a slot (not shown in the figure) for the rotation of the roller 603 on the inner side of the ring frame 601. A plurality of rollers 603 abut against the shaft body to limit the rotating shaft body. When the slide seat 401 moves horizontally, the ring frame 601 cooperates with the telescopic frame 604 to perform synchronous horizontal movement.
[0036] In summary, the bottom limit assembly 2 of the device cooperates with the peripheral limit assembly 3 to achieve external limit of the reduction gear box body 1. At the same time, the shaft limit assembly 6 can limit the reduction gear box shaft, thereby improving the operating stability of the gear reduction gear box and its connecting tooling.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
