Detailed implementation

[0021] Please refer to Figures 1-3 , and make further explanations for the embodiments of the present utility model;

[0022] A stress detection device for a composite arc groove cutter, including a base 1 and an operating table 9, and the operating table 9 is fixed on the base 1;

[0023] As Figure 1 shown, a horizontal transmission component is provided above the operating table 9, a rotary clamping member is installed on the operating table 9, at least one stress detection component 14 is installed on the lower side of the horizontal transmission component and at both clamping ends of the rotary clamping member. The stress detection component 14 on the lower side of the horizontal transmission component is used to detect the stress on the periphery of the composite arc groove cutter, and the remaining stress detection components 14 are respectively used to detect the stress at both ends of the composite arc groove cutter. The stress detection component 14 is a monitor based on X-ray diffraction, a monitor based on ultrasonic technology, or a monitor based on strain gauges in the prior art. And a camera 16 is also installed on the lower side of the horizontal transmission component. When the camera 16 works, it will take pictures of the state of the composite arc groove cutter during detection. The rotary clamping member is used to clamp the composite arc groove cutter;

[0024] It also includes a PLC controller 2 installed on the base 1. The signal receiving end of the PLC controller 2 is used to receive the detection signal of the stress detection component 14 and the shooting signal of the camera 16. The signal output end of the PLC controller 2 is used to control the opening and closing of the rotary clamping member. Under the use of the PLC controller 2, the device is made more automated.

[0025] When performing stress detection on the composite arc groove cutter, rotate the rotary clamping member to drive the composite arc groove cutter to rotate, and at the same time use the horizontal transmission component to drive the stress detection component 14 on its lower side to move horizontally, which is convenient for the stress detection component 14 to detect the stress on the periphery of the composite arc groove cutter. Through the joint use of the horizontal transmission component, the rotary clamping member and multiple stress detection components 14, the composite arc groove cutter can be subjected to comprehensive stress detection. At the same time, the camera 16 will also monitor the state of the composite arc groove cutter during detection, thereby greatly improving the accuracy of stress detection of the composite arc groove cutter.

[0026] As Figure 1As shown in the figure, the transverse transmission assembly includes a transverse guide rod 4, a movable sleeve 6, and a slider 8. A chute 5 for the slider 8 to slide is provided on the transverse guide rod 4. The movable sleeve 6 is sleeved on the transverse guide rod 4 and fixedly connected to the slider 8. The stress detection assembly 14 and the camera 16 on the transverse transmission assembly are both fixedly mounted on the lower side of the movable sleeve 6. A lifting rod 3 is fixedly mounted on the base 1, and the upper end of the lifting rod 3 is fixedly connected to one end of the transverse guide rod 4. In order to reduce the load on the lifting rod 3, the transverse guide rod 4, the movable sleeve 6, and the slider 8 are all made of hard plastic. When the movable sleeve 6 slides horizontally on the transverse guide rod 4, it can drive the stress detection assembly 14 and the camera 16 on its lower side to move together, so as to facilitate the stress detection of multiple positions of the composite circular arc groove cutter. The lifting rod 3 is used to adjust the heights of the transverse guide rod 4, the movable sleeve 6, and the stress detection assembly 14 and the camera 16 on the lower side of the movable sleeve 6.

[0027] As Figure 2 shown in the figure, the interior of the transverse guide rod 4 is hollow. The electric push rod 7 is horizontally fixed inside the transverse guide rod 4 and fixedly connected to the slider 8. A storage battery for supplying power to the electric push rod 7 is installed inside the transverse guide rod 4. When the electric push rod 7 is energized, it can slowly drive the slider 8 and the movable sleeve 6 to reciprocate on the transverse guide rod 4, making it more convenient for the stress detection assembly 14 on the lower side of the movable sleeve 6 to detect the stress of the composite circular arc groove cutter and the camera 16 to monitor the various states of the composite circular arc groove cutter.

[0028] As Figure 1 、 3 shown in FIGS. 3 and 4, the rotary clamping member includes a motor 10, a rotating rod 11, an electric push rod 13, and two clamping plates 12. The motor 10 is installed in the operating table 9, and the output end of the motor 10 penetrates through the inner wall of the operating table 9 and is fixedly connected to the rotating rod 11. The electric push rod 13 is disposed opposite to the rotating rod 11 and rotatably connected to the inner wall of the operating table 9. The two clamping plates 12 are respectively fixed to the ends of the rotating rod 11 and the output end of the electric push rod 13. Mounting holes for installing the stress detection assembly 14 are provided at the clamping ends of the clamping plates 12. An installation ring 17 surrounding the stress detection assembly 14 is fixedly mounted at the center of the clamping end of one of the clamping plates 12. A threaded hole is provided in the installation ring 17, and a limit screw 15 is threadedly connected in the threaded hole.

[0029] The specific operations during the use of the device are as follows:

[0030] As Figure 1 shown in the figure, the two clamping plates 12 are in an open state initially. The working intermittent times of the electric push rod 7, the motor 10, and the electric push rod 13 can be set through the PLC controller 2;

[0031] Before testing the compound circular arc groove cutter, insert the handle of the compound circular arc groove cutter into the mounting ring 17, tighten the limit screw 15, so that the inner end of the limit screw 15 limits the handle, and then click the PLC controller 2 to start the electric push rod 2 13 to drive the clamping plate 12 on it to approach the compound circular arc groove cutter. When the compound circular arc groove cutter is clamped by the two clamping plates 12, the PLC controller 2 turns off the power of the electric push rod 2 13; adjust the lateral guide rod 4, the movable sleeve 6, and the lifting rod 3 to adjust the lifting rod 3. The height of the stress detection component 14 and the camera 16 on the lower side of the movable sleeve 6 is to better detect the stress of the outer periphery of the composite arc groove cutter and to shoot the state of the composite arc groove cutter during detection. In order to make the device more convenient, the lifting rod 3 can be replaced with an electric lifting rod. It should be noted that since the clamping ends of the clamping plates 12 are provided with mounting holes for installing the force detection component 14, when the composite arc groove cutter is clamped, the composite arc groove cutter will not contact the stress detection component 14 at the clamping end of the clamping plates 12;

[0032] The body of the motor 10 is located inside the operating table 9. During the inspection, the PLC controller 2 is clicked to start the electric push rod 1 7 and the motor 10. The motor 10 is a reduction motor. When the motor 10 is working, it will drive the rotating rod 11 to rotate slowly, thereby driving the two clamping plates 12, the compound arc groove cutter and the electric push rod 2 13 to rotate on the operating table 9. During this process, the electric push rod 1 7 will drive the slider 8 to slide back and forth slowly in the slide groove 5, and then the slider 8 can drive the movable sleeve 6 to reciprocate on the transverse guide rod 4, and utilize the clamping and rotation functions of the rotary clamp and the transverse transmission component to transversely transmit the stress detection component 14 and the camera on its lower side. The camera 16 can realize the detection of multiple points around the periphery of the composite circular arc groove cutter. In addition, the stress detection component 14 at the clamping ends of the two clamping plates 12 can perform stress detection on the two ends of the composite circular arc groove cutter respectively. Because the structure around the periphery of the composite circular arc groove cutter is complex, while the structure at the two ends is relatively simple, the camera 16 is installed on the lower side of the transverse transmission component to record the dynamics around the periphery of the composite circular arc groove cutter to ensure the accuracy of the composite circular arc groove cutter detection. The detection signal of the stress detection component 14 and the shooting signal of the camera 16 will be received by the PLC controller 2, and the staff can view the detection and monitoring data through the PLC controller 2.
