Description

Technical Field

[0001] The utility model relates to the technical field of rotary reducer debugging, in particular to a debugging workbench for an involute tooth meshing rotary reducer. Background Art

[0002] After the production and assembly of the slewing reducer is completed, it is necessary to power on and debug the slewing reducer to ensure that the assembled slewing reducer has no quality problems. For example, in a multi-degree-of-freedom slewing reducer test bench disclosed in Chinese patent literature (patent number: CN201922052939.3), the up and down degrees of freedom can be adjusted by a screw rod, and the mounting frame can move left and right along the transverse guide rail. The motor can adjust the left and right degrees of freedom. The motor has two degrees of freedom, which is convenient for adjustment and installation with the reducer. A strain gauge is installed on the drive shaft, and the output torque of the reducer can be tested by the deformation of the drive shaft. However, the torque test of the slewing reducer is to test the torque limit of the slewing reducer, which is not suitable for debugging the slewing reducer. The above-mentioned patented fixing structure mainly facilitates the installation of the motor and the reducer, and is convenient for testing the torque. The fixing method is relatively complicated. For the debugging of the production and assembly of the slewing reducer, only simple fixing is required.

[0003] Therefore, we propose a debugging workbench for involute tooth meshing slewing reducer. Utility Model Content

The forward and reverse motor 17 is started between the two moving rods 90, and the forward and reverse motor 17 drives the worm 5 to rotate through the transmission shaft 16, and the worm 5 drives the worm wheel 4 to rotate, and the worm wheel 4 drives the fixed plate 7 to rotate through the connecting ring 6, and the fixed plate 7 rotates to drive the triangular push block 14, and the triangular push block 14 cooperates with the inclined surface of the positioning block 91 to push the positioning block 91 to move toward the center direction of the circular groove 8, and at the same time drives the first moving rod 9 and the second moving rod 90 to move, and the arc plate 11 set on the first moving rod 9 and the positioning plate 13 set on the second moving rod 91 are reversed. The rotary reducer 15 is fixed to facilitate the debugging of the rotary reducer 15, and the worm gear 4 and worm 5 are self-locking, so as to better fix the rotary reducer 15. After the debugging of various performances of the rotary reducer 15 is completed, the forward and reverse motors 17 are rotated in the opposite direction, so that the triangular push block 14 releases the fixation of the positioning block 91. When the triangular push block 14 completely releases the fixation of the positioning block 91, the staff is required to manually push the first moving rod 9 and the second moving rod 90 to ensure that the rotary reducer 15 is quickly separated from the debugging table 1.

[0019] Among them, a transmission shaft 16 is arranged at the right end of the worm 5, and a forward and reverse motor 17 is arranged at the right end of the transmission shaft 16.

[0021] A positioning block 91 is also provided at the bottom end of the second moving rod 90. One end of the positioning block 91 is provided as an inclined surface that matches the triangular push block 14. When the triangular push block 14 follows the rotation of the fixed plate 7, it matches with the inclined surface of the positioning block 91 to push the positioning block 91 to move.

[0022] There are three groups of first moving rods 9 and arc plates 11, and the three groups of first moving rods 9 and arc plates 11 are respectively located at the upper part, the lower part and the right side of the rotary reducer 15. The three groups of arc plates 11 fix the arc-shaped outer shell part of the rotary reducer 15, and the positioning plate 13 arranged on the second moving rod 90 fixes the plane part of the rotary reducer 15. The left side surface of the rotary reducer 15 is farther from the center of the arc surface of the rotary reducer than the arc surface of the rotary reducer 15 is from the center of the arc surface, so the distance difference between the two is compensated by the L-shaped support rod 12, so that the positioning plate 13 and the arc plate 11 fix the outer wall of the rotary reducer 15 at the same time.

[0023] Working principle: debug the rotary reducer 15, place the rotary reducer 15 on the top of the debugging platform 1, make the rotary reducer 15 between the first moving rod 9 and the second moving rod 90, start the forward and reverse motor 17, the forward and reverse motor 17 drives the worm 5 to rotate through the transmission shaft 16, the worm 5 drives the worm wheel 4 to rotate, the worm wheel 4 drives the fixed plate 7 to rotate through the connecting ring 6, the fixed plate 7 rotates and drives the triangular push block 14, the triangular push block 14 cooperates with the inclined surface of the positioning block 91, pushes the positioning block 91 to move toward the center of the circular groove 8, and drives the first moving rod 9 and The second moving rod 90 moves, and the arc plate 11 set on the first moving rod 9 and the positioning plate 13 set on the second moving rod 91 fix the rotary reducer 15, which is convenient for debugging the rotary reducer 15. After the debugging of various performances of the rotary reducer 15 is completed, the forward and reverse motors 17 are rotated in the opposite direction, so that the triangular push block 14 releases the fixation of the positioning block 91. When the triangular push block 14 completely releases the fixation of the positioning block 91, the staff is required to manually push the first moving rod 9 and the second moving rod 90 to ensure that the rotary reducer 15 is quickly separated from the debugging table 1.
