[0024] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0025] See also Figure 1 This embodiment provides a part torque detection device, including a positioning component 10, a clamping component 20 and a detection component 30. The positioning component 10 is used to position and place the part to be detected, the clamping component 20 is used to clamp the part, and the detection component 30 is used to perform torque detection on the part.

[0026] like Figure 2 As shown, the positioning assembly 10 includes three groups of positioning blocks 11 arranged at intervals along the same axis. Each positioning block 11 is provided with a positioning pin 12. The number and position of the positioning blocks 11 and the positioning pins 12 are determined according to the size of the part. The torque detection position of the part determines that the part is placed vertically, which in turn determines the arrangement of the positioning blocks 11. The positioning pins 12 are used to locate the inner hole at the bottom of the part.

[0027] In order to detect whether a part is placed on the positioning block 11 or whether the part is placed in place, a detection sensor 13 is provided on the positioning block 11. The detection sensor 13 is embedded in the positioning block, and the number of the detection sensors 13 is also determined according to the shape of the part.

[0028] like Figure 1 As shown, the clamping assembly 20 is used to clamp the position of the part on the two sets of positioning blocks at the end. According to the end surface of the part that can be clamped, in this embodiment, one set of clamping assemblies is used at one end and two sets of clamping assemblies are used at the other end. The structure of each set of clamping assemblies is consistent, so an example is given for any one set.

[0029] like Figure 3 As shown, the clamping assembly 20 includes a clamping cylinder 22 arranged through a vertical plate 21, a U-shaped plate 23 is arranged at the output end of the clamping cylinder 22, and a pressure plate 24 is rotatably arranged at the front end of the U-shaped plate 23. The pressure plate 24 is constructed as a structure with bent ends, which is also roughly U-shaped. One of the bent ends is used to clamp the parts, and the bent part of the other bent end is rotatably connected to the U-shaped plate through a pin. The free end near the bent part is rotatably provided with a rotating plate 25 through a pin, and the other end of the rotating plate 25 is rotatably connected to the vertical plate 21 through a pin, thereby realizing the downward pressing action of the pressure plate driven by the cylinder.

[0030] like Figure 4 As shown, the detection component 30 includes a mounting plate 31, a first slide rail 311 and a first cylinder 32 are provided on the mounting plate 31, a movable plate 33 is provided on the first slide rail 311, the output end of the first cylinder 32 is connected to the movable plate 33, a rotating motor 34 is provided on the movable plate 33, the output end of the rotating motor 34 is connected to the detection head 35 through the rotating shaft 341, and a torque sensor 36 connected to the rotating shaft 341 is also provided on the movable plate 33.

[0031] The function of the first cylinder 32 is to move the detection head 35 to the detection position on the part. When the positioning assembly 10 needs to replace different parts, the position of the detection head 35 needs to be adjusted. Therefore, a base plate 37 is provided under the mounting plate 31, and a second slide rail 371 and a second cylinder 38 are provided on the base plate 37. The mounting plate 31 is provided on the second slide rail 371. The output end of the second cylinder 38 is connected to the mounting plate 31. The position of the detection head is adjusted by the second cylinder to align it with the detection position.

[0032] When torque detection is required, the part is first fixed by the positioning assembly 10 and the clamping assembly 20, and then the first cylinder 32 is started to drive the detection head 35 to move to the torque detection position on the part, and then the rotary motor 34 is started to drive the detection head 35 to rotate. The detection head 35 is constructed as an L-shaped structure, so it can drive the structure of the torque detection position on the part to rotate, and then judge whether the torque is within the qualified range through the data of the torque sensor 36.

[0033] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
