Description

Technical Field

[0001] This utility model relates to the field of torque detection devices, and in particular to a simple torque detection platform for crankshaft pulleys. Background Technology

[0002] The assembly quality of components such as the main shaft, crankshaft, camshaft, and pistons in a car engine has a significant impact on engine performance. One of the key indicators of this impact is the magnitude of the frictional torque during crankshaft rotation. Excessive or insufficient crankshaft rotation torque indicates assembly defects and may cause the crankshaft to seize or spin freely, severely affecting the overall engine assembly.

[0003] When using the above-mentioned technology, the following technical problems were found in the existing technology: Existing crankshaft pulley torque testing equipment is often complex in structure and bulky in size, which not only results in high purchase costs but also cumbersome operation, making it inconvenient for use in some small repair shops or R&D testing scenarios. In addition, after testing the crankshaft pulley, the process of disassembling and replacing the crankshaft pulley is quite troublesome, consuming a lot of time and labor costs, and reducing testing efficiency. To address these issues, we designed a simplified crankshaft pulley torque testing platform to provide an alternative technical solution. Utility Model Content

A drive shaft is rotatably connected to one side of the torque sensor. A mounting shaft is fixed to the side of the drive shaft away from the torque sensor. The outer side of the mounting shaft is rotatably connected to the test chamber. A crankshaft pulley is slidably connected to the outer side of the mounting shaft. An external hexagonal bolt is rotatably connected to the other side of the torque sensor. The outer side of the external hexagonal bolt is rotatably connected to the test chamber.

[0006] As a preferred embodiment of the simple torque testing platform for crankshaft pulley provided by this utility model, a guide box is fixed at one end of the test box, an L-shaped plate is slidably connected to the inner side of the guide box, a limit shaft is rotatably connected to one end of the inner side of the L-shaped plate, and one side of the limit shaft passes through the crankshaft pulley and is slidably connected to the mounting shaft.

[0007] In a preferred embodiment of the simple torque testing platform for crankshaft pulley provided by this utility model, a mounting mandrel is fixed on the inner side of the mounting shaft, and one side of the limiting shaft passes through the crankshaft pulley and is slidably connected to the mounting mandrel.

[0012] At the same time, through the above technical solutions, this utility model has at least the following beneficial effects:

[0013] This utility model provides a simple torque testing platform for crankshaft pulleys. The crankshaft pulley is placed on the outside of the mounting shaft, while the mounting mandrel on the inside of the mounting shaft effectively resists the crankshaft pulley. Then, an electric push rod is activated to drive the L-shaped plate and the limiting shaft to apply pressure to the crankshaft pulley. As a result, the limiting shaft clamps the crankshaft pulley to the mounting mandrel. Then, a wrench drives the external hex bolt to rotate, which in turn moves the torque sensor, drive shaft, mounting shaft, and crankshaft pulley. At this time, the torque sensor effectively tests the torque of the crankshaft pulley and transmits the torque value to the display screen for easy testing of the crankshaft pulley, thereby enabling quick disassembly and replacement of the crankshaft pulley.

[0024] Example 1

[0025] Please refer to Figures 1-4 A simple torque testing platform for crankshaft pulleys includes a test chamber 1, a torque sensor 7 fixed inside the test chamber 1, a drive shaft 10 rotatably connected to one side of the torque sensor 7, a mounting shaft 11 fixed to the side of the drive shaft 10 away from the torque sensor 7, the outer side of the mounting shaft 11 rotatably connected to the test chamber 1, a crankshaft pulley 8 slidably connected to the outer side of the mounting shaft 11, an external hexagonal bolt 9 rotatably connected to the other side of the torque sensor 7, a wrench 3 sleeved on the outer side of the external hexagonal bolt 9, and the outer side of the external hexagonal bolt 9 rotatably connected to the test chamber 1.

[0026] When it is necessary to perform a torque test on the crankshaft pulley 8, the crankshaft pulley 8 is placed on the outside of the mounting shaft 11 and slidably connected to the mounting shaft 11. Then, pressure is applied to the wrench 3, which causes the hex bolt 9 to rotate. The hex bolt 9 causes the torque sensor 7, drive shaft 10, mounting shaft 11, and crankshaft pulley 8 to move. At this time, the torque sensor 7 effectively tests the torque of the crankshaft pulley 8, and then the torque sensor 7 transmits the torque value to the display screen 6 for display.

[0027] One end of the test box 1 is fixed with a guide box 2. An L-shaped plate 4 is slidably connected to the inside of the guide box 2. One end of the inside of the L-shaped plate 4 is rotatably connected with a limiting shaft 13. One side of the limiting shaft 13 passes through the crankshaft pulley 8 and is slidably connected to the mounting shaft 11. An mounting spindle 12 is fixed to the inside of the mounting shaft 11. One side of the limiting shaft 13 passes through the crankshaft pulley 8 and is slidably connected to the mounting spindle 12. One end of the guide box 2 is equipped with an electric push rod 5. The output end of the electric push rod 5 is fixed to the L-shaped plate 4.

[0028] When a torque test is required on the crankshaft pulley 8, the crankshaft pulley 8 is placed on the outside of the mounting shaft 11, while the mounting mandrel 12 on the inside of the mounting shaft 11 effectively resists the crankshaft pulley 8. Then, the electric push rod 5 is activated to drive the L-shaped plate 4 and the limiting shaft 13 to apply pressure to the crankshaft pulley 8. As a result, the limiting shaft 13 drives the crankshaft pulley 8 to clamp with the mounting mandrel 12, thereby effectively positioning the crankshaft pulley 8 and facilitating quick disassembly of the crankshaft pulley 8.

[0029] A display screen 6 is fixed at the other end of the test chamber 1. The torque sensor 7 is electrically connected to the display screen 6, and the torque value measured by the torque sensor 7 can be displayed through the display screen 6.
