DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1-Figure 3 , a speed reducer worm installation auxiliary positioning device, including a base 1, a fixing frame 4 is fixed to the top of the base 1 by bolts, and a slide 3 is slidably connected to the outer walls of the fixing frame 4. A power mechanism is provided on the top of the base 1 to drive the slide 3 to move, so that the slide 3 can move up and down, and both ends of the slide 3 are rotatably connected to support rods 7, and an adjustment mechanism for fixing the angle of the support rods 7 is provided between the two support rods 7. The adjustment mechanism can fix the rotation angle of the two support rods 7 so that the gap between the other ends of the two support rods 7 can be changed. The bottoms of the two support rods 7 are bonded with pads 8, and the pads 8 are in contact with the base 1. After the device is used, it is reset to assist in supporting the support rod 7. The bottoms of the two support rods 7 are welded with fixing plates 20, and one side of the fixing plate 20 is slidably connected to two guide rods 12. The two guide rods 12 A baffle 14 is fixed at one end by bolts to prevent the guide rod 12 from slipping off the fixing plate 20. One end of the two guide rods 12 passes through the fixing plate 20 and is fixed with a connecting plate 19 by bolts to clamp the worm. One side of the two fixing plates 20 is provided with a limiting mechanism for fixing the position of the guide rod 12, and one side of the two connecting plates 19 is provided with a fixing component for auxiliary clamping of the worm. Place one side of the reducer housing on the two adjusted support rods 7, then pass the worm through the reducer housing, push the guide rod 12, so that the fixing component on the connecting plate 19 contacts the worm, clamp the worm, and fix the guide rod 12 with the limiting mechanism. At this time, the other side of the reducer housing can be installed, and the position of the worm can be limited, so that there is no need to install the worm by hand, thereby improving the assembly efficiency of the reducer.

[0024] Among them, the power mechanism includes a cylinder 2, which is fixed to the top of the base 1 by bolts, and the cylinder 2 is fixed to the slide 3, which can drive the slide 3 to move, thereby adjusting the height of the support rod 7 to suit people of different heights.

[0025] Among them, the adjustment mechanism includes two rotating rods 5, and the two rotating rods 5 are rotatably connected to one side of the two support rods 7 respectively. A threaded hole 10 is opened on one side of the two rotating rods 5, and a screw rod 9 is threadedly connected to the threaded hole 10. A connecting block 6 is welded between the two screw rods 9. The connecting block 6 is rotated, and the connecting block 6 drives the two screw rods 9 to rotate. Under the action of the thread, the screw rod 9 is displaced from the inside of the rotating rod 5 to the outside, thereby completing the adjustment of the two support rods 7, so that the support rod 7 can better support the housing of the reducer.

[0026] Among them, the limiting mechanism includes two limiting plates 21, both of which are welded on one side of the fixed plate 20, a slider 22 is slidably connected between the two limiting plates 21, an insert plate 13 is clamped between the two sliders 22, and the insert plate 13 is in contact with the two limiting plates 21, and rubber pads 11 are bonded to the arc sides of the two sliders 22. Inserting the insert plate 13 between the two sliders 22 can squeeze the two sliders 22 to move toward the guide rod 12, and at the same time squeeze the rubber pad 11 to deform, thereby completing the fixation of the position of the guide rod 12.

[0027] Among them, the fixing assembly includes two telescopic rods 16, and the two telescopic rods 16 are fixed to one side of the connecting plate 19 by bolts. One end of the two telescopic rods 16 is fixed with a clamping plate 18 by bolts. Two springs 17 are welded on one side of the clamping plate 18, and the two springs 17 are fixed to the connecting plate 19. A sponge pad 15 is bonded to the other side of the clamping plate 18. The sponge pad 15 contacts one end of the worm. Continuing to push the connecting plate 19 to move will cause the worm to squeeze the clamping plate 18 and move toward the connecting plate 19, thereby causing the telescopic rod 16 to contract and the spring 17 to compress. When the reducer is installed, it is only necessary to directly pull out the worm. Under the action of the spring 17 and the telescopic rod 16, the clamping plate 18 and the sponge pad 15 are reset, and the two sponge pads 15 do not contact. When assembling a new reducer, there is no need to adjust other parts. It is only necessary to place the reducer housing on the support rod 7 and insert the worm between the two clamping plates 18 to complete the fixation of the worm, thereby further improving the assembly efficiency of the reducer.

[0028] Working principle: when the reducer needs to be assembled, first rotate the connecting block 6, and the connecting block 6 drives the two screw rods 9 to rotate. Under the action of the thread, the screw rod 9 is displaced from the inside of the rotating rod 5 to the outside, thereby completing the adjustment of the two struts 7, and then place one side of the reducer housing on the two adjusted struts 7, and then pass the worm through the reducer housing, push the guide rod 12, so that the sponge pad 15 on one side of the connecting plate 19 contacts the worm, and continue to push the connecting plate 19 to move, which will cause the worm to squeeze the splint 18 and move toward the connecting plate 19, thereby causing the telescopic rod 16 to contract and the spring 17 to compress. When the reducer is installed, just pull out the worm directly. Under the action of the spring 17 and the telescopic rod 16, the splint 18 and the sponge pad 15 are reset, and the two sponge pads 15 are not in contact. When assembling a new reducer, there is no need to adjust other parts. Just place the reducer housing on the strut 7 and insert the worm between the two splints 18 to complete the fixation of the worm.

[0029] Finally, it should be noted that: for those skilled in the art, they can still modify the technical solutions recorded in the above embodiments, or replace some of the technical features therein with equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of this utility model shall be included in the protection scope of this utility model.
