[0029] See also Figure 1-Figure 6 , which shows a schematic diagram of the structure of a torque test rotating mechanism implementation method of the utility model, please refer to Figure 1-Figure 6 , a torque test rotating mechanism is introduced in detail.

[0030] A torque test rotating mechanism comprises a base 100, a ring-shaped turntable 110 is rotatably arranged on the top of the base 100, a placement table 120 is arranged at the center of the turntable 110 on the top of the base 100, a gear-shaped part 130 to be tested is placed on the placement table 120, and a driving component for driving the turntable 110 to rotate is arranged on the top of the base 100;

[0031] The top of the base 100 is provided with a first fixing frame 200 and a second fixing frame 210 at equal intervals around the placing table 120 as the center. The first fixing frame 200 is arranged outside the circle of the turntable 110, and the second fixing frame 210 is arranged inside the circle of the turntable 110. A rotating drum 220 is rotatably penetrated through the side wall of the first fixing frame 200, and a clamping rod 230 is slidably penetrated through the side wall of the second fixing frame 210. A threaded rod 240 is arranged at one end of the clamping rod 230 close to the rotating drum 220, and the rod body of the threaded rod 240 is screwed into the inner cavity of one end of the rotating drum 220. A tooth-shaped stop block 250 is protruded from one side of the clamping rod 230 close to the part 130. A first bevel gear 260 is arranged on the outer side wall of the rod body of each rotating drum 220, and a second bevel gear 270 meshing with all the first bevel gears 260 is arranged on the top of the turntable 110.

[0032] All of the abutments 250 abut against the lower half of the part 130, and the upper half of the part 130 is sleeved and inserted into the bottom of the sleeve 300. The bottom slot of the sleeve 300 is consistent with the shape of the part 130. The sleeve 300 is arranged at the working end of the torque wrench. After the part 130 is placed on the top of the placement table 120, the lower half of the part 130 is clamped and fixed by multiple clamping rods 230, and then the sleeve 300 is sleeved on the upper half of the part 130. The sleeve 300 is twisted with the torque wrench until the part 130 is damaged, thereby connecting the deformation limit torque of the part 130.

[0033] Furthermore, a protective shell 150 is provided on the top of the base 100, and the inner cavity of the protective shell 150 accommodates the drive assembly, the first bevel gear 260 and the second bevel gear 270. The shaft of the rotating drum 220 and the shaft of the threaded rod 240 both have gaps passing through the side wall of the protective shell 150, and the protective shell 150 is provided to prevent the components from being directly exposed to the outside world.

[0034] Furthermore, the driving assembly includes a circle of external teeth 140 arranged on the outside of the turntable 110, a vertical servo motor 160 is arranged on one side of the top of the inner cavity of the protective shell 150, and a driving gear 170 is arranged at the output end of the servo motor 160. The teeth of the driving gear 170 are engaged with the external teeth 140. When the servo motor 160 is started, it drives the driving gear 170 to rotate, and then the turntable 110 is rotated through the external teeth 140.

[0035] Furthermore, a control switch 180 is disposed on the top of the base 100 . The control switch 180 is electrically connected to the servo motor 160 and an external power supply device. The servo motor 160 is controlled to be turned on and off by the control switch 180 .

[0036] Furthermore, vertical bolts 190 are threadedly provided around the top of the base 100 to fix the bolts 190 on a desired fixed plane, thereby fixing the device so that the base 100 as a whole will not move when the torque wrench is tested.

[0037] Furthermore, the clamping rod 230 is in the shape of a rectangular strip, and the outer walls of the clamping rod 230 are respectively fitted and passed through the second fixed frame 210. When the rotating drum 220 rotates, since the clamping rod 230 is in the shape of a rectangular strip, and the outer walls of the clamping rod 230 are respectively fitted and passed through the second fixed frame 210, the clamping rod 230 does not rotate, but the length of the threaded rod 240 in the hole of the rotating drum 220 is adjusted, that is, the position of the clamping rod 230 can be adjusted.

[0038] It should be noted that the hardness of the components designed for the present device is greater than the hardness of the component 130 , so as to avoid the clamping rod 230 and other components being damaged first when the component 130 is tested.

[0039] During specific use, the part 130 to be tested is placed on the top of the placement table 120. After the driving gear 170 is started by the control switch 180, the turntable 110 is driven to rotate by the external tooth 140. At this time, all the rotating drums 220 are driven to rotate simultaneously by the second bevel gear 270 and the first bevel gear 260, so as to adjust the length of the threaded rod 240 in the hole of the rotating drum 220, that is, the position of the clamping rod 230 can be adjusted, so that the multiple clamping rods 230 gradually move beyond the position of the part 130. After the lower half of the part 130 is clamped and fixed by multiple clamping rods 230, the fixation of gear-shaped parts 130 of different models can be completed, and then the sleeve 300 is put on the upper half of the part 130, and the sleeve 300 is twisted by the torque wrench until the part 130 is damaged, thereby connecting the deformation limit torque of the part 130.

[0040] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
