Abstract
Description
Technical Field
[0001] The utility model relates to the field of tensioning wheel assembly, in particular to a tensioning wheel pre-twist and torque detection device. Background Art
[0002] A tensioner is a follower pulley that presses against the belt to change the pulley's wrap angle or control belt tension. It is a crucial component of the belt drive tensioning system. It primarily consists of a friction element, torsion spring, bearing, pulley, and other components. Tensioners are widely used in engines of motors, automobiles, conveyors, and lifting equipment, ensuring the stability and reliability of the transmission system by automatically adjusting belt tension.
[0003] Currently, during the assembly process of the tensioner, the tensioner components are assembled and then pre-tightened manually. After the pre-tightening is completed, the staff uses a handheld torque meter to test the torque of the tensioner components. The whole process takes a lot of time and the staff has high workload, which affects the assembly efficiency of the tensioner.
[0004] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present disclosure, and therefore may include information that does not constitute prior art known to ordinary technicians in the field.

[0024] Example:
[0025] A tensioning wheel pre-twist and torque detection device, such as Figure 1 As shown, it includes a rotary workbench 1, on which a loading platform 11 is provided. During operation, the tensioning wheel is placed on the loading platform 11. After the rotary workbench 1 completes a process, the rotary workbench 1 rotates to send the loading platform 11 with the tensioning wheel to the next workstation.
[0026] Combine Figure 1 and Figure 2 As shown, a tensioning pulley pre-tightening and torque detection device includes a pre-tightening device 2, which is mounted on a rotary worktable 1 and tightens the tensioning pulley. The pre-tightening device 2 includes a fixed frame 21 and a reducer 22. The fixed frame 21 is mounted on the table of the rotary worktable 1. The fixed frame 21 is provided with a vertically arranged electric guide rail 211, on which a slide 221 is slidably connected. The reducer 22 is mounted on the slide 221 and is located on top of the fixed frame 21. The slide 221 reciprocates up and down on the electric guide rail 211, and the reducer 22 also reciprocates in the same manner.
[0027] like Figure 2 As shown, the shaft of the reducer 22 is connected to the rotating wheel 222, and the bottom of the rotating wheel 222 is plugged with an eccentrically arranged pin 223. When working, the pin 223 is inserted into the tensioning wheel, and the reducer 22 is started to drive the rotating wheel 222 to rotate, thereby tightening the tensioning wheel.
[0028] Combine Figure 1 and Figure 3 As shown, a tensioning pulley pre-tightening and torque detection device includes a torque testing device 3, which is mounted on a rotary worktable 1 and is located next to the pre-tightening device 2. The torque testing device 3 includes a second fixing frame 31 and a second reducer 32. The second fixing frame 31 is fixed to the tabletop of the rotary worktable 1. The second fixing frame 31 is provided with a second electric guide rail 311 arranged in a vertical direction. A second slide 321 is slidably connected to the second electric guide rail 311. The second reducer 32 is mounted on the second slide 321. The slide 321 and the second reducer 32 can reciprocate up and down along the second electric guide rail 311.
[0029] like Figure 3 As shown, the shaft of the second reducer 32 is fitted with a second runner 322. A torque sensor 323 is connected to the bottom of the second runner 322. The bottom of the torque sensor 323 is connected to the third runner 324. An eccentrically arranged second latch 325 is inserted into the bottom of the third runner 324. When testing the torque of the tensioning pulley, the second slide 321 moves downward, inserting the second latch 325 into the tensioning pulley. The second reducer 32 is activated, driving the second runner 322 and the third runner 324 to rotate. At this point, the torque sensor 323 detects torque data.
[0030] Specific working principle:
[0031] First, the staff puts the tensioning wheel on the loading platform 11, first starts the rotating workbench 1, and transports the tensioning wheel to the pre-tightening device 2. The reducer 22 descends to insert the pin 223 into the tensioning wheel. The reducer 22 starts to drive the runner 222 to rotate, thereby twisting the tensioning wheel. Finally, the reducer 22 rises and resets. After that, the rotating workbench 1 is started again to transport the tensioning wheel to the torque testing device 3. The reducer 2 32 descends to insert the pin 2 325 into the tensioning wheel. The reducer 2 32 starts, and the runner 2 322 and the runner 3 324 rotate. At this time, the pin 2 325 twists the tensioning wheel. At this time, the torque sensor 323 transmits the torque data to the outside world, and measures the torque of the pre-tightened parts. The torque must reach the set requirement range.

In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
