Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figure 1 , 2 As shown, a PVC pipe strength detection device comprises a processing table 1, a first support table 2 is slidably mounted on one side of the upper surface of the processing table 1, a second support table 3 is fixedly mounted on the other side of the upper surface of the processing table 1, a support side plate 9 is slidably mounted on the upper surface of the processing table 1, a servo motor 6 is fixedly mounted on one side of the processing table 1, a screw rod 7 is mounted on the output end of the servo motor 6, a screw rod sleeve 8 is sleeved and mounted in the middle of the screw rod 7, the screw rod sleeve 8 is connected to the support side plate 9, a second hydraulic cylinder 10 is fixedly mounted on the lower surface of the support side plate 9, a guide plate 11 is mounted on the output end of the second hydraulic cylinder 10, a punch head 12 is fixedly mounted on the lower surface of the guide plate 11, and a positioning component 4 is arranged on the guide plate 11.

[0021] like Figure 1 , 2 As shown, a first hydraulic cylinder 5 is fixedly installed on one side of the upper surface of the processing table 1, and the output end of the first hydraulic cylinder 5 is arranged on the side of the first supporting platform 2. The output end of the first hydraulic cylinder 5 is extended and retracted to drive the first supporting platform 2 to move forward, thereby adjusting the distance between the first supporting platform 2 and the second supporting platform 3, and adjusting the distance between the first supporting platform 2 and the second supporting platform 3 to a suitable length for the pipe.

[0022] like Figure 2 , 3As shown, a slide groove 13 is provided on the upper surface of the processing table 1, and a slider 14 is fixedly installed on the lower surface of the first support platform 2. The slider 14 is slidably installed inside the slide groove 13. By sliding the slider 14 inside the slide groove 13, the stability can be better when the first support platform 2 moves.

[0023] like Figure 2 , 3 As shown in , 4, the positioning assembly 4 includes a mounting rod 402 and a guide groove 404. The mounting rod 402 is fixedly mounted on the upper surfaces of the first support platform 2 and the second support platform 3. The guide groove 404 is provided on the lower surface of the guide plate 11. A clamping plate 403 is slidably mounted in the middle of the mounting rod 402. A limited clamping groove 401 is provided on the mutually adjacent sides of the clamping plate 403, the first support platform 2 and the second support platform 3. A guide block 405 is slidably mounted inside the guide groove 404. A first return spring 406 is fixedly mounted on the lower surface of the guide block 405. A connecting plate 407 is fixedly mounted on the lower end of the first return spring 406. A second return spring 408 is fixedly mounted on the lower surface of the connecting plate 407. The top end of the second return spring 408 is arranged on the upper surface of the clamping plate 403 and is retracted and extended through the output end of the second hydraulic cylinder 10. At this time, the guide plate 11 can be driven downward. When the pipe is moved, the clamping plate 403 can be driven to move downward, and the two ends of the pipe can be positioned between the two limit clamping grooves 401, which can fix the pipe and prevent the pipe from warping or shifting at both ends when the pipe is colliding. The quality of the inspection is improved. Due to the first return spring 406 and the second return spring 408, after the pipe is fixed between the limit clamping grooves 401, it will not affect the guide plate 11 to continue to move forward, so that the punch head 12 can move forward to collide with the pipe. The strength detection device for the pipe is performed, and the output end of the servo motor 6 drives the screw rod 7 to rotate, so that the screw rod screw sleeve 8 moves in the middle of the screw rod 7. At this time, the supporting side plate 9 can be driven to move, so the punch head 12 can be driven to move left and right, so that the punch head 12 performs collision detection on different positions of the pipe, thereby improving the comprehensiveness of the inspection.

[0024] The working principle of this PVC pipe strength testing device:

[0025] When in use, when the device is needed, firstly, the output end of the first hydraulic cylinder 5 is extended and retracted to drive the first support platform 2 to move forward, so as to adjust the distance between the first support platform 2 and the second support platform 3, and adjust the distance between the first support platform 2 and the second support platform 3 to a suitable length of the pipe. At this time, the two ends of the pipe are placed between the two limit clamping grooves 401. At this time, the output end of the second hydraulic cylinder 10 is extended and retracted. At this time, the guide plate 11 can be driven to move downward, and because a clamping plate 403 is slidably installed in the middle of the mounting rod 402, a limit clamping groove 401 is provided on the side where the clamping plate 403, the first support platform 2, and the second support platform 3 are close to each other, and a guide block 405 is slidably installed inside the guide groove 404, and a first return spring 406 is fixedly installed on the lower surface of the guide block 405, and a connecting plate 407 is fixedly installed on the lower end of the first return spring 406, and a second return spring 408 is fixedly installed on the lower surface of the connecting plate 407. The top end of the return spring 408 is set on the upper surface of the clamping plate 403, and at this time, the clamping plate 403 can be driven to move downward, positioning the two ends of the pipe between the two limit clamping grooves 401, fixing the pipe, and preventing the pipe from warping or position shifting at both ends when the pipe is colliding, thereby improving the quality of detection. Because of the first return spring 406 and the second return spring 408, after the pipe is fixed between the limit clamping grooves 401, it will not affect the guide plate 11 to continue to move forward, so that the punch head 12 can move forward to collide with the pipe, and perform strength detection on the pipe. The output end of the servo motor 6 drives the screw rod 7 to rotate, so that the screw rod screw sleeve 8 moves in the middle of the screw rod 7, and at this time, the support side plate 9 can be driven to move, so that the punch head 12 can be driven to move left and right, so that the punch head 12 performs collision detection on different positions of the pipe, thereby improving the comprehensiveness of the detection.

[0026] The above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
