[0028] See also Figure 1-Figure 5 , which shows a schematic diagram of the structure of a part torque testing mechanism of the utility model, please refer to Figure 1-Figure 5 , a parts torque testing mechanism is introduced in detail.

[0029] A parts torque testing mechanism, comprising a fixed frame 100, the fixed frame 100 is in a rectangular frame shape, the inner side wall of the fixed frame 100 is provided with two parallel rotating rods 110 for forward and backward rotation, the left and right sides of the rod body of each rotating rod 110 are provided with external threads 120 with opposite thread directions, and the external threads 120 on the same side of the left and right sides are screwed together to provide a clamping plate 130;

[0030] The left end of each rotating rod 110 extends through the left side wall of the fixed frame 100 in a rotating manner and is provided with a worm gear 200. An installation plate 210 is arranged on the left side wall of the fixed frame 100. A driving rod 220 is rotatably arranged through the side wall of the installation plate 210. The driving rod 220 is located above the left end of the rotating rod 110 and is perpendicular to it. A worm 230 meshing with the worm gear 200 is arranged on the rod body of the driving rod 220;

[0031] A "冂"-shaped fixing frame 300 is fixedly installed in the middle of the top edge of the fixed frame 100. A lifting plate 310 is arranged inside the fixing frame 300 in a lifting manner. A vertical torque testing motor 320 is arranged at the center of the top of the lifting plate 310. The output end of the torque testing motor 320 rotatably penetrates through the center of the bottom wall of the lifting plate 310 and is provided with a connecting frame 330. A torque sensor for monitoring the torque of the output shaft of the torque testing motor 320 is arranged on the lifting plate 310;

[0032] A mounting cylinder 400 is detachably arranged below the connecting frame 330. The mounting cylinder 400 is located directly above the two clamping plates 130. A card slot 410 is opened at the lower end of the mounting cylinder 400. The shape of the card slot 410 is the same as that of the nut 510 of the bolt 500 to be tested. The bolt 500 includes a screw rod 520 clamped between the two clamping plates 130 and a nut 510 screwed on the rod body of the screw rod 520;

[0033] In actual production, multiple models of mounting cylinders 400 are provided. The card slots 410 at the bottoms of different models of mounting cylinders 400 are different. The models of these mounting cylinders 400 are the same as the models of the bolts 500 required for the vehicle, so that when testing bolts 500 of different models, the corresponding mounting cylinders 400 can be replaced.

[0034] Further, the front and rear sides of the side wall of the clamping plate 130 are respectively screwed by external threads 120 on the same side. Anti-slip lines are arranged on the side where the two clamping plates 130 are close to each other, which improves the friction force between the two clamping plates 130 and the outer side wall of the screw rod 520.

[0035] Further, a display screen 140 is arranged on the front side wall of the fixed frame 100. The torque sensor is electrically connected to the display screen 140. A control switch 150 is arranged on the front side wall of the fixed frame 100. The control switch 150 is electrically connected to the torque testing motor 320. A processor is also installed on the fixed frame 100, and the processor is electrically connected to the torque sensor and the display screen 140. When the torque sensor monitors the torque of the output shaft of the torque testing motor 320, it sends the data to the processor. After the processor processes the data, the data is digitized and displayed on the display screen 140, so as to facilitate the user to read the current torque output by the torque testing motor 320.

[0036] Furthermore, a hollow outer shell 240 is provided on the left side wall of the fixing frame 100, and the outer shell 240 wraps the worm gear 200, the mounting plate 210 and the driving rod 220. After the outer shell 240 wraps the components in its inner cavity, the components are prevented from being exposed to the outside world. The front end of the driving rod 220 extends and rotates through the front side wall of the outer shell 240. A hand crank 250 is provided at the front end of the driving rod 220, and the hand crank 250 is used to conveniently drive the driving rod 220 to rotate, thereby driving the two rotating rods 110 to rotate in the same direction at the same time through the worm 230 and the worm gear 200. Since the left and right sides of the rod body of each rotating rod 110 are provided with external threads 120 with opposite thread directions, the external threads 120 on the same side of the left and right sides are screwed together with a clamping plate 130, so that the two clamping plates 130 move in opposite directions at the same time to achieve clamping or loosening of the screw 520.

[0037] Furthermore, vertical slide grooves 350 are symmetrically opened on the left and right side walls of the fixing frame 300, and a vertical slide rod 360 is fixedly arranged between the upper and lower inner walls of the slide groove 350. The left and right sides of the lifting plate 310 slide on the inner walls of the slide groove 350, and the rod body of the slide rod 360 slides vertically through the upper and lower walls of the lifting plate 310. A handle 370 is arranged on the front side of the lifting plate 310, and an anti-slip sleeve 380 is sleeved on the handle 370. The position of the lifting plate 310 is adjusted by the handle 370, so as to facilitate the placement of the bolt 500 inside the fixing frame 100, and also facilitate the replacement of different types of mounting tubes 400 after the lifting plate 310 is lifted.

[0038] Furthermore, a transverse mounting groove 340 is provided at the bottom center of the connecting frame 330, and a connecting piece 420 is protruded from the top of the mounting tube 400 and is adapted to be inserted into the mounting groove 340. A socket 430 is aligned between the connecting frame 330 and the connecting piece 420, and a matching pin 440 is inserted into the inner side of the socket 430.

[0039] In the specific use process, the model of the required installation tube 400 is first determined according to the model of the bolt 500 to be tested. When replacing the installation tube 400, the plug 440 is pulled out from the hole 430, and the connecting member 420 is taken out from one side of the installation groove 340 to replace a different installation tube 400.

[0040] When testing the bolt 500, first lift the lifting plate 310, then place the bolt 500 to be tested between the two clamping plates 130, and then use the hand crank 250 to drive the driving rod 220 to rotate. At this time, the worm 230 and the worm wheel 200 drive the two rotating rods 110 to rotate in the same direction at the same time. Since the left and right sides of the rod body of each rotating rod 110 are provided with external threads 120 with opposite thread directions, the two clamping plates 130 move in opposite directions at the same time to clamp the screw 520. Then, the handle 370 is slowly driven to install the screw 520. The installation cylinder 400 descends, so that the nut 510 is inserted into the hole of the slot 410, and then the torque test motor 320 is started to drive the installation cylinder 400 to rotate, thereby tightening the nut 510. When the torque sensor detects the torque of the output shaft of the torque test motor 320, it is sent to the processor. After the processor processes the data, it digitizes the data and displays it on the display screen 140, so that the user can read the torque currently output by the torque test motor 320, thereby understanding the torque of the bolt 500 and realizing the testing of bolts 500 of different models.

[0041] 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.
