Description

Technical Field

[0001] The utility model relates to the technical field of detection devices, in particular to a coupling torque detection device. Background Art

[0002] A coupling is a device that connects two shafts or a shaft and a rotating part, rotates together during the transmission of motion and power, and does not disengage under normal circumstances. Sometimes it is also used as a safety device to prevent the connected parts from being subjected to excessive loads, playing the role of overload protection. By testing the torque borne by the coupling through a torque detection device, its mechanical properties and mechanical properties under working conditions can be understood, and then whether it meets the design requirements and use standards can be evaluated.

[0003] For example, a coupling torque detection device with publication number CN215573507U has accurate detection and convenient clamping. The coupling torque detection device is provided with a first clamp and a second clamp. The coupling is placed on the second clamp, and then the first threaded rod is rotated. The first threaded rod drives the first clamp to move through the slider. When it moves to a suitable position, the first clamp clamps the coupling, and then the servo motor is started. The servo motor drives the first clamp to rotate, and the coupling is rotated. The torque detector can perform torque detection on the coupling, which is convenient for more accurate torque detection of the coupling.

[0004] The above-mentioned coupling torque detection device still has the following shortcomings in actual use: the main structure of the above-mentioned coupling torque detection device includes a base and a fixed block, and the top surface of the base and the side surface of the fixed block are provided with clamps, which can clamp the coupling to facilitate torque detection of the coupling, but the setting of the base and the fixed block will make the coupling torque detection device larger in size, which will be very inconvenient to carry and transport. Therefore, a coupling torque detection device is needed to solve the above problems. Utility Model Content

[0005] The purpose of the present invention is to solve at least one of the above technical deficiencies.

[0006] Therefore, one purpose of the present invention is to provide a coupling torque detection device to solve the problems mentioned in the background technology and overcome the deficiencies in the prior art.

[0007] In order to achieve the above-mentioned objectives, an embodiment of one aspect of the utility model provides a coupling torque detection device, including a storage frame, the top of the storage frame is rotatably connected to a cover plate by a hinge, the cover plate is clamped with the storage frame by a snap assembly, the interior of the storage frame is slidably connected to a carrying plate, the interior of the storage frame is rotatably connected to a lead screw, the lead screw is threadedly connected to the carrying plate, the top surface of the carrying plate is fixedly connected to a support plate, one side of the support plate is fixedly connected to a motor, the output end of the motor is fixedly connected to a rotating disk, the side of the rotating disk away from the motor is fixedly connected to a torque sensor, one side of the torque sensor is fixedly connected to a first clamp, the top surface of the carrying plate is fixedly connected to a sliding frame, the interior of the sliding frame is rotatably connected to a threaded column, the outer surface of the threaded column is threadedly connected to a movable plate, one side of the movable plate is fixedly connected to a second clamp, the second clamp corresponds to the first clamp.

[0008] Preferably, any of the above schemes has two limit posts fixedly connected to the inner wall of the sliding frame, the two limit posts are symmetrically distributed on both sides of the threaded column, and the limit posts are slidably connected to the movable plate.

[0009] Preferably, in any of the above schemes, the movable plate and the supporting plate are both perpendicular to the carrying plate, and the movable plate is slidably connected to the sliding frame.

[0010] Preferably, any of the above solutions has a controller fixedly connected to the top surface of the carrier plate, and the motor and the torque sensor are electrically connected to the controller.

[0011] Preferably, any of the above solutions has a guide rod fixedly connected to the inner wall of the storage frame, and the guide rod is slidably connected to the bearing plate.

[0012] Preferably, any of the above schemes has a baffle fixedly connected to the top of the storage frame, a control knob fixedly connected to the bottom of the screw rod, the axis of the screw rod coincides with the control knob, and the screw rod is rotatably connected to the baffle via a bearing.

[0013] Compared with the prior art, the advantages and beneficial effects of the utility model are:

[0014] When the torque detection operation of the coupling is required, one point of the coupling can be locked by the second clamp, and then the threaded column is rotated. The movable plate can be driven to move left and right through the threaded transmission until the coupling moves away from one end of the second clamp and approaches the first clamp. The other end of the coupling is locked by the first clamp, and couplings of different lengths can be clamped. Then, the motor is turned on to rotate it through the rotating disk, and the coupling can be twisted. The torque of the coupling can be detected by the torque sensor. After the detection operation is completed, the control knob is twisted to drive the screw rod to rotate. The bearing plate can be driven downward by threaded transmission until the bearing plate moves to the bottom of the storage frame, and is locked with the storage frame through the snap assembly cover plate. The torque detection component can be stored inside the storage frame, which is more convenient to carry. BRIEF DESCRIPTION OF THE DRAWINGS
