[0026] According to an embodiment of the utility model, a placement table for testing the clamping force of a clamp is provided.

[0027] Embodiment 1;

[0029] The measuring material 1 is used to measure the deformation caused by the clamping force of the clamp structure 6. The deformation of the measuring material 1 is then detected by a radar device, and the clamping force of the clamp structure 6 is known through the deformation amount. The two connecting ears of the clamp structure 6 are used to apply force to open its elastic clamp 601, wherein the pressure structure 3 is required to cooperate with the contact structure to act on the connecting ears to open its clamp, and the correction structure 2 is used to adjust the position of the pressure structure 3 so that the force applied by the contact structure remains perpendicular to the connecting ears, thereby accurately measuring the force required to open the clamp.

[0030] The correction structure 2 includes a guide rail groove 201, an X-axis motor 202, a first threaded rod 203, a transmission thread block 204, a connecting shaft 205, a Y-axis motor 206, and a second threaded rod 207. The guide rail groove 201 is respectively provided with an X-axis guide rail and a Y-axis guide rail.

[0032] The pressurizing structure 3 includes a driving motor 301, a threaded sleeve rod 302, a connecting rod 303, an adjusting threaded block 304, a transmission rod 305, a connecting block 306, a pressure sensor 307, a connecting lug 308, a guide rail 309, a supporting universal wheel 310, and a laser emitter 311.

[0033] The driving motor 301 drives the threaded sleeve 302 to transmit on the connecting rod 303, thereby driving the adjustment thread block 304 and the connecting block 306 to move, wherein one side end of the connecting rod 303 is fixedly connected to the connecting block 306, so that it is pushed forward by the contact structure connected by rotating the connecting ear 308, so that it applies pressure to the connecting ear, and the size data of the applied force can be obtained through real-time detection by the pressure sensor 307.

[0034] The first contact structure 4 includes a first pressure plate 401, a first limiting block 402, and a first laser receiver 403. The first pressure plate 401 contacts the first connecting ear 602. The first limiting block 402 is fixedly connected to one side of the first pressure plate 401. The first laser receiver 403 is provided on the side of the first pressure plate 401 adjacent to the first limiting block 402.

[0035] The second contact structure 5 includes a second pressure plate 501, a second limiting block 502, and a second laser receiver 503. The second pressure plate 501 contacts the second connecting ear 603. The second limiting blocks 502 are fixedly connected to both ends of the second pressure plate 501, and the second laser receiver 503 is fixedly connected to one side of the second pressure plate 501.

[0036] The first limit block 402 of the first contact structure 4 is located between the connecting ears when the first pressure plate 401 contacts the first connecting ear 602, and plays a limiting role. The second limit blocks 502 of the second contact structure 5 are located at both ends of the second connecting ear 603, and also play a limiting role. When the pressure plate applies pressure to the connecting ear, the side surface of the plate will fit with the connecting ear, thereby causing its laser receiver to shift. The correction of the correction structure 2 will keep the pressure applied by the pressure plate perpendicular to the connecting ear.

[0037] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process is described in detail below.

[0038] In summary, with the aid of the above technical solution of the utility model, the measuring material 1 is used to measure the deformation caused by the clamping force of the clamp structure 6, and then the deformation of the measuring material 1 is detected by a radar device, and then the clamping force of the clamp structure 6 is known through the deformation amount, and the two connecting ears of the clamp structure 6 are used to apply force to open its elastic clamp 601, wherein the pressure structure 3 needs to cooperate with the contact structure to act on the connecting ears to open its clamp, and the correction structure 2 is used to adjust the position of the pressure structure 3 so that the force applied by the contact structure remains perpendicular to the connecting ears, thereby accurately measuring the force required to open the clamp, and the guide rail The slot 201 adjusts the position of the transmission thread block 204 by respectively transmitting the first threaded rod 203 and the second threaded rod 207 through the X-axis motor 202 and the Y-axis motor 206. The X-axis motor 202 and the Y-axis motor 206 are servo-controlled by the control module. The control module monitors the linear distance and offset angle between the laser transmitter 311 of the pressurized structure 3 and the laser receiver in real time. The laser receiver is internally integrated with a beam angle offset monitoring device, which can measure the offset of the beam. The offset angle of the beam receiving point can be calculated through the offset and the linear distance of the beam, and then the X-axis The transmission control of the motor 202 and the Y-axis motor 206 moves the driving motor 301 of the pressurizing structure 3 to a suitable position, keeps the distance of the laser beam consistent, and thus ensures the verticality of the pressure applied by the contact structure to the connecting ear of the clamp structure 6, so that accurate data related to the clamp opening and the applied force can be obtained. The driving motor 301 drives the threaded sleeve rod 302 to transmit on the connecting rod 303, thereby driving the adjustment thread block 304 and the connecting block 306 to move, wherein one side end of the connecting rod 303 is fixedly connected to the connecting block 306, so that it is pushed forward by the contact structure connected by the connecting ear 308. It applies pressure to the connecting ear, and the size of the applied force can be obtained through real-time monitoring of the pressure sensor 307. The first limit block 402 of the first contact structure 4 is located between the connecting ears when the first pressure plate 401 contacts the first connecting ear 602, and plays a limiting role. The second limit blocks 502 of the second contact structure 5 are at both ends of the second connecting ear 603, and also play a limiting role. When the pressure plate applies pressure to the connecting ear, the side of the plate will fit with the connecting ear, thereby causing its laser receiver to shift. The pressure applied by the pressure plate will be kept perpendicular to the connecting ear through the correction of the correction structure 2.
