Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.

[0028] As Figures 1-4The utility model discloses the technical scheme as follows is shown: a kind of speed reducer assembly auxiliary tool, including support plate 3, the top of support plate 3 is rotatably connected with rotary drum 4. The top of support plate 3 is fixedly connected with first motor 11, and first motor 11 drives rotary drum 4 rotation.

[0029] The inside of rotary drum 4 is fixedly connected with fixed plate 13, and the top end of the output shaft of first motor 11 is fixedly connected to the bottom of fixed plate 13. The output shaft of first motor 11 is coaxially arranged with fixed plate 13 and rotary drum 4. The output shaft of first motor 11 drives fixed plate 13 to rotate, and then makes rotary drum 4 rotate.

[0030] The bottom of rotary drum 4 is fixedly connected with a limiting ring, and the top surface of support plate 3 is provided with a limiting slot, and the limiting ring is slidably connected in the limiting slot. Rotary drum 4 will drive the limiting ring to rotate in the limiting slot when rotating, and the limiting ring is used to limit rotary drum 4, so as to increase the stability of rotary drum 4.

[0031] The top of rotary drum 4 is rotatably provided with turnover plate 6.

[0032] The outer surface of turnover plate 6 is fixedly connected with two second rotating shafts 18, and the ends of the two second rotating shafts 18 are rotatably connected to the inside of rotary drum 4. There is a gap between the outer surface of turnover plate 6 and the inner wall of rotary drum 4. Turnover plate 6 is positioned on rotary drum 4 through second rotating shaft 18, so as to facilitate the rotation of turnover plate 6.

[0033] A mounting hole 15 is formed in turnover plate 6, and a sliding block 17 is slidably arranged in the mounting hole 15. A sliding groove 20 is formed in each of the two inner walls corresponding to the mounting hole 15, and a first rotating shaft 16 in cylindrical shape is fixedly connected to the two sides of the sliding block 17 and is slidably arranged in the corresponding sliding groove 20. The sliding block 17 slides in the mounting hole 15, drives the first rotating shaft 16 to slide in the corresponding sliding groove 20, and the first rotating shaft 16 can rotate in the corresponding sliding groove 20, so that the sliding block 17 rotates in the mounting hole 15.

[0034] A driving assembly is arranged on rotary drum 4, and the driving assembly drives the sliding block 17 to vertically move up and down.

[0035] The driving assembly comprises a second motor 12, and the second motor 12 is fixedly connected to the bottom of fixed plate 13. A lead screw 14 is fixedly connected to the output end of the second motor 12, the bottom end of the lead screw 14 penetrates through fixed plate 13, and the top end of the lead screw 14 penetrates through the mounting hole 15. The lead screw 14 is vertically arranged, and the sliding block 17 is threadedly sleeved on the lead screw 14. When the lead screw 14 rotates, the sliding block 17 is driven to vertically move up and down, and the sliding block 17 drives turnover plate 6 to rotate through the first rotating shaft 16.

[0036] Two clamping assemblies are symmetrically arranged on the top of turnover plate 6.

[0037] The clamping assembly comprises a fixed block 7 and a clamping plate 8, the fixed block 7 is fixedly connected with the top of the turnover plate 6, and the clamping plate 8 is slidingly connected to the top of the turnover plate 6. A threaded rod 5 is threaded through the fixed block 7, and the end of the threaded rod 5 is fixedly connected with a rotating disc, which is rotatably connected to the inside of the clamping plate 8. When the threaded rod 5 rotates, the rotating disc rotates inside the clamping plate 8, and the threaded rod 5 moves on the fixed block 7, which pushes the clamping plate 8 to slide on the top of the turnover plate 6 through the rotating disc.

[0038] Both ends of the clamping plate 8 are fixedly connected with sliding rods 19, and the two sliding rods 19 are slidingly penetrated through the fixed block 7. When the clamping plate 8 slides, it drives the sliding rods 19 to slide on the fixed block 7, and the sliding rods 19 limit the clamping plate 8 to increase the stability of the clamping plate 8.

[0039] The top of the turnover plate 6 is fixedly connected with a positioning plate 9, and the positioning plate 9 is located between the two clamping plates 8 and away from one end of the sliding block 17. When assembling the speed reducer, the shell of the speed reducer is placed on the top of the turnover plate 6 and located on one side of the positioning plate 9, which is positioned by the positioning plate 9.

[0040] The top of the support plate 3 is fixedly connected with an L-shaped lamp holder 10, and the end of the lamp holder 10 away from the support plate 3 is fixedly installed with an illuminating lamp, which is located directly above the middle of the fixed plate 13. The illuminating lamp has the effect of illumination.

[0041] The bottom of the support plate 3 is uniformly fixedly connected with four hydraulic cylinders 2, and the bottom ends of the four hydraulic cylinders 2 are fixedly connected with the same base 1. The four hydraulic cylinders 2 can push the support plate 3 up and down to adjust the height of the turnover plate 6, so as to adapt to different heights of the workers.

[0042] Working principle:

[0043] In use, the hydraulic cylinder 2 is started to push the support plate 3 up or down. Thus, the height of the turnover plate 6 is adjusted to adapt to the height of the worker. The illuminating lamp on the lamp holder 10 is turned on.

[0044] Place the speed reducer shell on the top of the turnover plate 6 and on one side of the positioning plate 9. The speed reducer shell is located between the two clamping plates 8.

[0045] Rotate the threaded rod 5 to rotate the rotating disc at the end of the threaded rod 5 inside the clamping plate 8. When the threaded rod 5 rotates, it moves on the fixed block 7, and the threaded rod 5 pushes the clamping plate 8 to slide on the top of the turnover plate 6 through the rotating disc, and the sliding rod 19 slides on the fixed block 7.

[0046] The clamping plate 8 moves to the speed reducer shell until the two clamping plates 8 cooperate to clamp the speed reducer shell, thereby fixing the speed reducer shell on the top of the turnover plate 6.

[0047] When the angle of the turnover plate 6 needs to be adjusted during the assembling process.

[0048] Start the first motor 11, the output shaft of the first motor 11 drives the fixed plate 13 to rotate, and drives the rotating drum 4 to rotate on the top of the support plate 3. The rotating drum 4 drives the turnover plate 6 to rotate, and adjusts the angle of the turnover plate 6 in the horizontal direction.

[0049] Start the second motor 12, and drive the screw rod 14 to rotate. The screw rod 14 drives the sliding block 17 to move up and down, and the sliding block 17 will push the turnover plate 6 through the first rotating shaft 16 when moving up and down. Since the first rotating shaft 16 can only move up and down with the sliding block 17, and the second rotating shaft 18 limits the turnover plate 6, the first rotating shaft 16 will push the turnover plate 6 to rotate, so that the mounting hole 15 will rotate relatively when sliding on the sliding block 17, and the sliding groove 20 will rotate relatively when sliding on the first rotating shaft 16. Thus, the angle of the turnover plate 6 is adjusted in the vertical direction.

[0050] After the assembling is completed, rotate the screw rod 5, and the screw rod 5 pulls the clamping plate 8 through the rotating disc, so that the clamping plate 8 can be separated from the reducer shell.

[0051] Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement to part of the technical features, and any modification, equivalent replacement, improvement, etc. within the spirit and principles of the utility model should be included in the protection scope of the utility model.
