Description

Technical Field

[0001] This utility model relates to the field of motor testing technology, and in particular to a quick clamping device and a motor shaft torque testing device. Background Technology

[0002] In the field of motor manufacturing and maintenance, the torque performance of the motor shaft end is one of the key technical indicators for measuring the quality, reliability, and service life of a motor. Torque testing is not only related to verifying the motor's output capability, but also directly affects its operational stability and safety after integration into a complete set of equipment.

[0003] Traditional testing methods typically rely on operators using simple tools such as manual torque wrenches for sampling tests. This method is not only inefficient and difficult to meet the needs of modern production lines for full inspection or high-frequency sampling, but its test results are also easily affected by human operation techniques, force, and reading deviations, resulting in poor data repeatability and low accuracy.

[0004] In existing technologies, traditional clamping methods for motor torque detection often employ bolt clamps or multiple sets of independent screws for direct fastening. This approach has significant limitations: the clamping process is cumbersome and time-consuming, requiring operators to repeatedly tighten multiple bolts, resulting in high labor intensity and severely restricting production cycle time and testing efficiency. Secondly, the bolt tightening force is difficult to control; excessive tightening may damage the motor housing or cause housing deformation, thus affecting the internal air gap and performance of the motor, while excessive looseness will cause shaking during torque loading, leading to inaccurate test data or even safety accidents. Finally, traditional fixtures have poor adaptability to motors of different shapes and sizes, often requiring replacement or adjustment of fixture components, resulting in insufficient versatility.

[0007] Preferably, a limit frame is hinged to the rotary handle, and the limit frame is fixedly connected to the fixed frame. The setting of the limit frame restricts the range of motion of the rotary handle, prevents excessive rotation, and ensures the stability and safety of clamping.

[0008] Preferably, a hollow sleeve is slidably provided on the outer side of the extension arm, and the hollow sleeve is fixedly connected to the fixing frame.

[0011] Preferably, a slide rail is fixedly provided on the inner bottom surface of the mounting bracket, and the slide rail is slidably connected to the base.

[0012] Preferably, the input end of the torque detector is fixedly equipped with a coupling, which is used to connect with the output shaft of the motor to be tested.

[0013] This utility model provides a quick clamping device and a motor shaft head torque detection device, which, compared with the prior art: 1. This utility model can quickly complete the clamping and releasing of the motor through the linkage drive mechanism. Compared with the traditional bolt locking method, it eliminates the need for tools and repeated tightening steps, reduces the labor intensity of operators, and greatly improves the inspection cycle. At the same time, the design of the rubber clamping plate effectively avoids hard damage to the motor housing, combining high efficiency and protection of the workpiece.

[0014] 2. In terms of detection accuracy, this utility model integrates a quick clamping module with a precision sliding torque detector.

[0018] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0019] Please refer to Figures 1-2This utility model provides a quick clamping device, including a base 1, and a support frame 10 fixedly disposed above the base 1. A fixing frame 11 is fixedly disposed above the support frame 10, and a clamping assembly 12 for pressing a motor is disposed on the fixing frame 11. The clamping assembly 12 includes a sliding sleeve 120 fixedly connected to the fixing frame 11, and a lifting rod 121 is slidably disposed on the inner side of the sliding sleeve 120. A clamping plate 122 is fixedly disposed at one end of the lifting rod 121, and the clamping plate 122 is made of rubber. A control component is disposed at the end of the lifting rod 121 away from the clamping plate 122, and the control component is used to drive the lifting rod 121 to move. By pressing down on the control component, the lifting rod 121 is driven to slide vertically downward in the sliding sleeve 120, thereby causing the rubber clamping plate 122 to press against the housing of the motor to be tested, thus completing the clamping.

[0020] like Figure 2 and Figure 3 As shown, the control component includes a U-shaped member 123 fixedly connected to the lifting rod 121, and a connecting arm 124 is hinged to the U-shaped member 123. An extension arm 125 is hinged to the end of the connecting arm 124 away from the U-shaped member 123, and a rotating handle 126 is hinged to the end of the extension arm 125 away from the connecting arm 124. When the rotating handle 126 is pressed down, the rotational motion of the handle is converted into a linear downward motion of the U-shaped member 123 and the lifting rod 121 through the linkage mechanism composed of the extension arm 125 and the connecting arm 124. Lifting the handle can raise the clamping plate 122, thus realizing the smooth transmission of motion.

[0021] To limit the range of motion of the rotary handle 126 and prevent excessive rotation, a limit bracket 127 is hinged to the rotary handle 126, and the limit bracket 127 is fixedly connected to the fixed bracket 11.

[0022] In order to guide and support the extension arm 125, reduce swaying during movement, and improve the accuracy and reliability of clamping, a hollow sleeve 128 is slidably provided on the outer side of the extension arm 125, and the hollow sleeve 128 is fixedly connected to the fixing frame 11.

[0023] like Figure 4 As shown, on the other hand, this application also provides a motor shaft torque detection device with a quick clamping device, including a detection mechanism 2 fixedly connected to a base 1. The detection mechanism 2 includes a mounting frame 26, and a torque detector 20 is provided on the mounting frame 26. A base 21 is fixedly provided below the torque detector 20, and the base 21 is slidably connected to the mounting frame 26. A coupling 27 is fixedly provided at the input end of the torque detector 20, and the coupling 27 is used to connect with the output shaft of the motor to be tested. In use, after the motor to be tested is fixed on the base 1 with the quick clamping device, the base 21 is pushed or driven to slide on the mounting frame 26, so that the coupling 27 at the input end of the torque detector 20 is connected with the output shaft of the motor, and torque detection can be performed.

[0024] In order to achieve automatic position adjustment of torque detector 20 and reduce manual intervention, a connecting plate 22 is fixedly installed above the base 21, and a connecting rod 23 is fixedly installed on the connecting plate 22. An electric telescopic rod 24 is installed at the end of the connecting rod 23 away from the connecting plate 22, and the electric telescopic rod 24 is fixedly connected to the mounting frame 26.

[0025] To ensure the smoothness and straightness of the torque detector 20 during movement and to avoid deviation, a slide rail 25 is fixedly provided on the inner bottom surface of the mounting bracket 26, and the slide rail 25 is slidably connected to the base 21.

[0026] In summary, during use, the operator first places the motor to be tested on the base 1, then presses down the rotating handle 126. The linkage mechanism, consisting of the extension arm 125 and the connecting arm 124, converts the rotational motion into the linear lifting of the U-shaped part 123, which in turn pulls the lifting rod 121 to slide upward in the sliding sleeve 120, so that the rubber clamping plate 122 leaves the motor to provide placement space. After placing the motor, the rotating handle 126 is lifted up, and the linkage mechanism drives the lifting rod 121 to move downward in the opposite direction until the clamping plate 122 stably presses against the motor housing to complete the quick clamping. Subsequently, the electric telescopic rod 24 is activated to push the base 21 to slide along the slide rail 25, so that the coupling 27 at the input end of the torque detector 20 is precisely connected with the output shaft of the clamped motor. Finally, the equipment is started to perform torque testing.

[0027] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
