[0019] Example

[0020] In order to solve the above technical problems, this embodiment provides a rotating shaft assembly torque testing device, such as Figure 1-2 As shown, it includes a base 10, a torque detection component 20 arranged on the base 10, and a clamping component 30 for clamping a rotating sleeve. The torque detection component 20 is connected to the rotating shaft, and a driving component 40 is connected to the end of the clamping component 30 away from the detection component 20. The driving component 40 is used to drive the clamping component 30 to rotate relative to the torque detection component 20. The torque detection component 20 is set to clamp the rotating shaft, and then the clamping component 30 clamps the rotating sleeve. Under the drive of the driving component 40, the clamping component 30 is rotated through the transmission component 50, so that the rotating sleeve on the clamping component 30 rotates, and drives the rotating shaft on the torque detection component 20 to rotate, and then the torque when the rotating sleeve and the rotating shaft rotate is detected by the torque detection component 20, and then it is determined whether the assembly and cooperation of the rotating sleeve and the rotating shaft are qualified, thereby improving the detection efficiency and detection accuracy.

[0021] In order to detect and analyze the torque data of the rotating shaft, as a preferred embodiment, the torque detection component 20 includes a first mounting seat 21 that rotates with the rotating shaft and a torque tester 22 arranged on one side of the first mounting seat 21. The rotating shaft passes through the first mounting seat 21 and is connected to the torque tester 22. By setting the torque tester 22, when the rotating shaft and the rotating sleeve in the torque detection component 20 and the clamping component 30 rotate relative to each other, the torque of the rotating sleeve and the rotating shaft during rotation is detected by the torque tester 22, and then it is determined whether the assembly cooperation of the rotating sleeve and the rotating shaft is qualified, so as to distinguish whether the rotating shaft component to be detected is a good product.

[0022] As a preferred embodiment, the first mounting seat 21 is provided with a bearing 23, and the rotating shaft can be rotatably engaged with the first mounting seat 21 through the bearing 23. By providing the bearing 23, the rotating shaft is connected to the torque tester 22 through the bearing 23, so as to ensure the rotation accuracy of the rotating shaft assembly, so as to cooperate with the torque tester 22 to detect and analyze the rotational torque of the rotating shaft and the rotating sleeve.

[0023] In order to realize the relative rotation between the rotating sleeve and the rotating shaft, as a preferred embodiment, the clamping assembly 30 includes a second mounting seat 31 for clamping the rotating sleeve, and a second clamping cylinder 32 is installed on the top of the second mounting seat 31.

The rotating sleeve is placed on the second mounting seat 31, and the rotating sleeve is clamped by the second clamping cylinder 32. The driving assembly 40 drives the transmission assembly 50 to rotate, and then the clamping assembly 30 is driven to rotate by the transmission assembly 50, so as to cooperate with the torque meter to detect and analyze the torque of the rotating shaft.

By setting the transmission assembly 50, the driving assembly 40 drives the clamping assembly 30 and the rotating sleeve to rotate coaxially.

[0025] Since the second clamping cylinder 32 needs to be connected to an external air source through an air pipe, in order to prevent the air pipe from getting tangled as the second clamping cylinder 32 rotates, as a preferred embodiment, an air groove is opened along the axis of the second transmission shaft 53. By opening the air groove on the second transmission shaft 53, a rotatable air pipe joint is set at one end of the air groove, and the air pipe joint is connected to the external air source through the air pipe 531. The other end of the air groove is connected to the second clamping cylinder 32 through the air pipe, thereby providing an air source for the second clamping cylinder 32. The second transmission shaft 53 and the air pipe joint rotate relative to each other, thereby preventing the air pipe from being directly connected to the second clamping cylinder 32 and causing the air pipe to rotate and get tangled.

[0026] As a preferred embodiment, the clamping assembly 30 also includes a plurality of sliders 33 arranged at the bottom of the second mounting seat 31. The base 10 is provided with a slide groove 11 that slides in cooperation with the slider 33. By setting the slider 33, the second mounting seat 31 can be moved. After the rotating sleeve is installed on the clamping assembly 30, the second mounting seat 31 is driven close to the torque detection assembly 20 so that the rotating shaft on the rotating sleeve is connected to the torque detection assembly 20 to cooperate with the torque detection assembly 20 to complete the detection of the rotating shaft assembly.

[0027] As a preferred embodiment, the slider 33 is fixedly connected to the second mounting seat 31 via a locking member.

[0028] As a preferred embodiment, a driving cylinder is provided at the bottom of the base 10 for driving the clamping assembly 30 to move closer to or away from the torque detection assembly 20. By providing the driving cylinder, the clamping assembly 30 can be automatically driven closer to or away from the torque detection assembly 20 to cooperate with the detection of the rotating shaft assembly and improve production efficiency.
