The pressure plate 4 is installed in the U-shaped frame 2 through a telescopic adjustment mechanism 3 for driving the pressure plate to move perpendicularly to the radial direction of the pipe to be tested and a translation adjustment mechanism 8 for driving the pressure plate to move axially along the pipe to be tested. A fixed T-plate 5 and a sliding T-plate 6 are respectively provided on both sides of the interior of the U-shaped frame 2, and a bearing ring 7 for supporting the pipe to be tested is respectively provided on the side close to the fixed T-plate 5 and the sliding T-plate 6. The sliding T-plate 6 is installed on the inner side of the U-shaped frame 2 through a mounting mechanism 9 located on the outer side of the U-shaped frame. The schematic diagram of the mounting mechanism 9 is shown in FIG. Figure 4 As shown, it includes a first connecting plate 91, a support plate 92, a sliding plate 93 and a reset spring 12. The sliding T-plate 6 is fixedly connected to the first connecting plate 91 at one end located on the outside of the U-shaped frame 2, and the support plate 92 is fixedly connected to the outside of the U-shaped frame 2, and the first connecting plate 91 is vertically connected to the support plate 92. The first connecting plate 91 is slidably connected to the sliding plate 93 on the side away from the sliding T-plate 6, and the support plate 92 is provided with a No. 1 card slot 94 for plugging the sliding plate 93, and the bottom end of the sliding plate 93 is located in the No. 1 card slot 94. The two ends of the reset spring 12 are fixedly connected to the outside of the U-shaped frame 2 and the first connecting plate 91, respectively.

[0026] In this embodiment, the schematic diagram of the translation adjustment mechanism 8 is as follows Figure 3As shown, it includes a motor 81 fixedly mounted on the rear side of the U-shaped frame 2 through a fixing plate 80, the output shaft of the motor 81 is connected to a transmission disc 83 through a rotating shaft 82, a straight plate 84 is provided at the front side of the transmission disc 83, an arc hole 85 is provided on the surface of the straight plate 84, and connection holes 86 are provided at the top and bottom of the arc hole 85, a translation driving rod 87 extending into the arc hole 85 is fixedly connected to the front side of the transmission disc 83, a second connecting plate 88 is fixedly connected to the side of the straight plate 84 close to the telescopic adjustment mechanism 3, a sliding sleeve 890 is fixedly connected to the end of the second connecting plate 88, a sliding rod 89 is fixed inside the U-shaped frame 2, the sliding sleeve 890 is slidably connected to the sliding rod 89, and the bottom end of the sliding sleeve 890 is fixedly connected to the telescopic adjustment mechanism 3. A slide rail 10 is provided at the top of the interior of the U-shaped frame 2, one end of the force-bearing sliding rod 11 is fixedly connected to the sliding sleeve 890, and the other end is slidably connected to the slide rail 10. When the telescopic end of the telescopic adjustment mechanism 3 drives the pressure plate 4 to press down the pipe for detection, the sliding sleeve 890 will be subjected to an upward reaction force, and the reaction force will be transmitted to the force-bearing sliding rod 11. Under the action of the sliding rail 10, the phenomenon of the sliding rod 89 being broken due to excessive reaction force can be avoided.

When the pipe is stressed, part of the pressure will be transferred to the fixed T-plate 5 and the sliding T-plate 6. At this time, the stress ribs 14 can prevent the fixed T-plate 5 and the sliding T-plate 6 from breaking and strengthen the strength of the fixed T-plate 5 and the sliding T-plate 6.

[0029] In order to facilitate automatic control, a controller 15 is fixedly connected to the front side of the testing platform 1, and the control signal output end of the controller 15 is connected to the control signal input end of the motor 81, thereby facilitating strength testing of different positions of the pipe fitting and improving the degree of automation.

[0030] For easy operation, a handle is provided on the sliding plate 93 .

[0031] During operation, the sliding plate 93 is slid upward to disengage the bottom end of the sliding plate 93 from the No. 1 slot 94, and then the sliding plate 93 is pulled outward, the sliding plate 93 drives the sliding T-plate 6 to slide, and the distance between the two bearing rings 7 increases, and the automobile pipe to be inspected is inserted on the outer side of the bearing ring 7 on the fixed T-plate 5, and then the sliding plate 93 slides in the opposite direction, and the sliding plate 93 drives the sliding T-plate 6 to slide toward one side of the pipe until the bearing ring 7 on the sliding T-plate 6 is inserted into the inner side of the end of the pipe, and the sliding plate 93 is inserted into the No. 1 slot 94 again, and the pipe to be inspected is placed between the two bearing rings 7, so that the pipe is fixed after installation, which is conducive to ensuring the stability of the pipe during inspection.

[0032] After the pipe to be inspected is fixed, the telescopic adjustment mechanism (hydraulic cylinder) 3 is controlled to drive the pressing plate 4 to press down and squeeze the pipe. Then the telescopic end of the telescopic adjustment mechanism (hydraulic cylinder) drives the pressing plate 4 to rise. The motor 81 is powered on, the output end of the motor 81 drives the rotating shaft 82 to rotate, the rotating shaft 82 drives the transmission plate 83 to rotate, the transmission plate 83 drives the translation drive rod 87 to rotate, the translation drive rod 87 drives the straight plate 84 to move horizontally through the arc hole 85 and the connecting hole 86, the straight plate 84 drives the second connecting plate 88 to move horizontally, the second connecting plate 88 drives the sliding sleeve 890 to move horizontally, the sliding sleeve 890 drives the telescopic adjustment mechanism (hydraulic cylinder) 3 to move horizontally along the sliding rod 89, the telescopic adjustment mechanism (hydraulic cylinder) 3 drives the pressing plate 4 to move horizontally, the pressing plate 4 can perform extrusion detection on different positions of the pipe, which is conducive to obtaining the data of the strength that can be borne at different positions, improving the accuracy of the equipment detection, and facilitating the staff to judge the strength of the vehicle pipe.

[0033] After the inspection is completed, the sliding plate 93 is slid upward to disengage the bottom end of the first card slot 94, and then the sliding plate 93 is pulled outward, and the sliding plate 93 drives the sliding T plate 6 to slide, and the distance between the two bearing rings 7 increases, and the pipe to be inspected is removed. The first connecting plate 91 is pulled and released, and the reset spring 12 drives the first connecting plate 91 to automatically restore, thereby driving the sliding T plate 6 to automatically reset, without manual sliding reset, and the sliding plate 93 is inserted into the first card slot 94.

[0034] In order to facilitate the installation of pipe fittings, the support plate 92 is also provided with a second card slot 13 for inserting the sliding plate. The second card slot 13 is the same size as the first card slot 94. The bottom end of the sliding plate 93 can be located in the first card slot 94 or the second card slot 13 according to the use requirements. When the sliding plate is located in the first card slot, before installing the pipe fitting, the first connecting plate 91 is slid so that the sliding plate 93 is inserted into the second card slot 13, thereby eliminating the need to pull the first connecting plate 91 all the time, which provides convenience.
