The warm light tube shines on the top of the hydraulic valve assembly, and the hydraulic valve assembly begins to heat up, so that the detection tooling can simulate the outdoor high temperature environment to perform gap detection, thereby preventing the equipment from failing to detect the pressure resistance of the hydraulic valve assembly gap in a high temperature environment, resulting in poor equipment detection effect.

In addition, the arc-shaped heat insulation board blocks the warm light tube from irradiating to the rubber roller, so that the rubber roller will not be irradiated by the warm light tube, thereby preventing the rubber roller from being irradiated by the warm light tube and causing rapid aging and damage to the rubber roller.

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] See also Figure 1-Figure 8 , one embodiment of the present invention is: a hydraulic valve assembly detection tool, including a base frame 1, slide grooves are opened on both sides of the top surface of the base frame 1, a U-shaped frame 2 is fixed on the top surface of the base frame 1, an electric cylinder 3 is fixedly installed in the middle of the top surface of the U-shaped frame 2, the telescopic end of the electric cylinder 3 penetrates and is slidably connected with the middle of the top surface of the U-shaped frame 2, a pressure plate 4 is fixed on the bottom surface of the electric cylinder 3, a humidity sensor 5 penetrates and is fixedly installed in the middle of the top surface of the base frame 1, and a leak-proof ring is arranged on the edge of the top surface of the pressure plate 4, the humidity sensor 5 is located between the two slide grooves of the base frame 1, the pressure plate 4 moves downward to the inner diameter above the hydraulic valve assembly, the pressure plate 4 applies pressure to the liquid in the hydraulic valve assembly, when the liquid in the hydraulic valve assembly flows down from the gap of the hydraulic valve assembly, the humidity sensor 5 will immediately sense it, and the humidity sensor 5 calculates whether the gap size of the hydraulic valve assembly meets the hydraulic shock according to the formula P (hydraulic pressure) = p (liquid density) × g (gravitational acceleration of the pressure plate 4 on the liquid) × h (ten centimeters);

[0032] A positioning assembly 11 is provided at the bottom end of the bottom frame 1. The positioning assembly 11 includes two T-shaped ring frames 111. The two T-shaped ring frames 111 are fixed to the bottom end of the bottom frame 1. Double-groove screws 112 are rotatably installed on the inner walls of the two T-shaped ring frames 111. Spiral grooves are provided on both sides of the outer wall of the double-groove screw 112. The two spiral grooves of the double-groove screw 112 spiral in opposite directions. A rotating shaft of a servo motor 113 is fixed to the right end of the double-groove screw 112. The bottom surface of the servo motor 113 is fixedly connected to the bottom end of the bottom frame 1. Transverse tube plates 114 are slidably installed on the two spiral grooves of the double-groove screw 112. The inner walls of the two transverse tube plates 114 are meshed with the inner walls of the two spiral grooves of the double-groove screw 112. The two transverse tube plates 114 are meshed with each other. 4 The outer wall is slidably connected with the inner walls of the two slide grooves of the bottom frame 1. Two short rods 115 are respectively passed through and fixed on the top of the side of the two cross tube plates 114 close to each other. Two arc-shaped rubber pads 116 are respectively fixed on the ends of the two short rods 115 close to each other. The hydraulic valve on the bottom frame 1 is on the movement track of the two arc-shaped rubber pads 116. The arc-shaped rubber pads 116 contact the surface of the hydraulic valve assembly. Under the action of the extrusion force, the arc-shaped rubber pads 116 push the hydraulic valve assembly to the middle of the bottom frame 1, so that the upper inner diameters of the pressure plate 4 and the hydraulic valve assembly are aligned, so as to avoid the upper inner diameter of the hydraulic valve assembly being squeezed and damaged by the pressure plate 4 when the detection work is in use due to the misalignment of the upper inner diameters of the pressure plate 4 and the hydraulic valve assembly.

[0033] An anti-shake component 12 is provided on the outer wall of the two short rods 115, and the anti-shake component 12 includes four struts 121. The four struts 121 are fixed on the outer walls of the two short rods 115 in groups of two. Two spring rods 122 are fixed on the top surfaces of the four struts 121, and two arc pads 123 are fixed on the sides of the telescopic ends of the two spring rods 122 that are close to each other. The two spring rods 122 are respectively located above the two cross tube plates 114, and the arc pads 123 are against the surface of the hydraulic valve assembly. When the hydraulic valve assembly gap is pressed down for detection, the elastic force of the spring rods 122 reduces the shaking of the hydraulic valve assembly on the base frame 1, so as to avoid the hydraulic valve assembly shaking on the base frame 1 during the detection work, resulting in inaccurate detection data.

[0034] When in use, place the hydraulic valve assembly in the center of the chassis 1, let the humidity sensor 5 be in the lower diameter of the hydraulic valve assembly, close the hydraulic valve assembly, inject liquid to a height of ten centimeters into the inner diameter above the hydraulic valve assembly, and the staff starts the electric cylinder 3 on the U-shaped frame 2. The telescopic end of the electric cylinder 3 moves downward, and the telescopic end of the electric cylinder 3 drives the pressure plate 4 to move downward. The pressure plate 4 moves downward into the inner diameter above the hydraulic valve assembly, and the pressure plate 4 applies pressure to the liquid in the hydraulic valve assembly. When the liquid in the hydraulic valve assembly flows down from the gap of the hydraulic valve assembly, the humidity sensor 5 will immediately sense it, and the humidity sensor 5 immediately closes the telescopic end of the electric cylinder 3 and moves downward. At the same time, the humidity sensor 5 calculates whether the gap size of the hydraulic valve assembly meets the hydraulic shock according to the formula P (hydraulic) = p (liquid density) × g (gravitational acceleration of the pressure plate 4 on the liquid) × h (ten centimeters). The humidity sensor 5 sends the data to the computer through the wireless network, so that the staff can immediately know the detection data. Because the hydraulic valve assembly is difficult to press the hydraulic valve assembly when the gap is detected. The inner diameters above are aligned. Before testing the hydraulic valve assembly, the staff starts the servo motor 113 in the chassis 1, and the shaft of the servo motor 113 starts to rotate forward. The shaft of the servo motor 113 drives the double-groove screw 112 to rotate forward. The double-groove screw 112 rotates forward in the T-shaped ring frame 111. Under the restriction of the slide groove of the chassis 1, the two transverse tube plates 114 move toward the middle in the two spiral grooves of the double-groove screw 112. The transverse tube plates 114 move toward the middle in the slide groove of the chassis 1, and the transverse tube plates 114 drive the short rod 115 to the middle. The short rod 115 drives the arc-shaped rubber pad 116 to move toward the middle, and the arc-shaped rubber pad 116 contacts the surface of the hydraulic valve assembly. Under the action of the extrusion force, the arc-shaped rubber pad 116 pushes the hydraulic valve assembly to the middle of the base frame 1, so that the upper inner diameters of the pressure plate 4 and the hydraulic valve assembly are aligned, thereby preventing the pressure plate 4 and the upper inner diameters of the hydraulic valve assembly from being misaligned when the equipment is in use, thereby avoiding the problem that the upper inner diameter of the hydraulic valve assembly is squeezed and damaged by the pressure plate 4 due to the misalignment of the pressure plate 4 and the upper inner diameters of the hydraulic valve assembly when the detection work is in use.

[0035] While the cross tube plate 114 drives the short rod 115 to move toward the middle, the short rod 115 drives the support rod 121 to move toward the middle, the support rod 121 drives the spring rod 122 to move toward the middle, and the telescopic end of the spring rod 122 drives the arc pad 123 to move toward the middle. In the process of the arc pad 123 moving toward the middle, the arc pad 123 contacts the surface of the hydraulic valve assembly. Under the action of the extrusion force, the telescopic end of the spring rod 122 moves in the spring rod 122, so that the arc pad 123 is against the surface of the hydraulic valve assembly. When the hydraulic valve assembly gap is pressed down for detection, the elastic force of the spring rod 122 reduces the shaking of the hydraulic valve assembly on the base frame 1, thereby preventing the hydraulic valve assembly from shaking on the base frame 1 when the equipment is in use, thereby avoiding the problem of inaccurate detection data caused by the shaking of the hydraulic valve assembly on the base frame 1 during the detection work.

[0036] See also Figure 1-Figure 8 On the basis of the above embodiment, another embodiment of the present invention further includes a heating device 6 and a pressure valve device 7, wherein the heating device 6 is provided on the side where the two spring rods 122 are away from each other, and the heating device 6 includes two L-shaped plates 61, two triangular blocks 62, two square shells 63 and a plurality of warm light tubes 64, the two L-shaped plates 61 are respectively fixed on the side where the two spring rods 122 are away from each other, the two triangular blocks 62 are respectively fixed on the ends where the two L-shaped plates 61 are close to each other, and the two square shells 63 are respectively fixed on the two triangular blocks 62. On one side of the corner block 62 away from the two L-shaped plates 61, a number of warm light tubes 64 are respectively fixed on the inner walls of the two square shells 63. The two square shells 63 are in an eight-shape. The two square shells 63 are located on the left and right sides of the pressure plate 4. When the warm light tubes 64 move toward the middle, the warm light tubes 64 shine on the top of the hydraulic valve assembly, and the hydraulic valve assembly begins to heat up, allowing the detection tooling to simulate the outdoor high temperature environment for gap detection, thereby avoiding the detection tooling failing to detect the pressure resistance of the hydraulic valve assembly gap in a high temperature environment, resulting in poor equipment detection effect.

[0037] The heating device 6 also includes two connecting blocks 65, two double-ring rods 66 and two thin rods 67. The two connecting blocks 65 are respectively fixed on the top of the side of the two L-shaped plates 61 away from each other, and the two double-ring rods 66 are respectively fixed on the side of the two connecting blocks 65 away from each other. The two thin rods 67 respectively penetrate and are fixed on the left and right sides of the inner wall of the U-shaped frame 2. The inner walls of the two double-ring rods 66 are slidably connected with the outer walls of the two thin rods 67. The two thin rods 67 are located on the front and back of the pressure plate 4. When the L-shaped plate 61 moves toward the middle, the double-ring rods 66 restrict the L-shaped plate 61, so that the L-shaped plate 61 will not vibrate violently during the movement toward the middle, so as to avoid the L-shaped plate 61 vibrating violently when the detection tooling is in use, which may cause the warm light tube 64 to be easily damaged.

[0038] The outer wall of the heating device 6 is provided with a pressure valve device 7, which includes four inclined rods 71, two U-shaped plates 72, two arc-shaped spring pieces 73 and two rubber rollers 74. The four inclined rods 71 ​​are respectively rotatably mounted on the outer walls of the two double-ring rods 66 in groups of two. The two U-shaped plates 72 are respectively fixed to one end of the four inclined rods 71 ​​away from the two double-ring rods 66, and the two arc-shaped spring pieces 73 are respectively fixed in the middle of one side of the two U-shaped plates 72 close to the four inclined rods 71. The ends of the two arc-shaped spring pieces 73 away from the two U-shaped plates 72 are connected to the two rubber rollers 74. The outer wall of the L-shaped plate 61 is fixedly connected, and the two rubber rollers 74 are rotatably installed on the inner walls of the two U-shaped plates 72 respectively. The two U-shaped plates 72 are in an inverted eight-shaped shape. The top surface of the hydraulic valve on the base frame 1 is on the movement trajectory of the two rubber rollers 74. The rubber rollers 74 are tightly pressed against the top of the hydraulic valve assembly, simulating the extrusion state of the hydraulic valve assembly during installation, thereby increasing the accuracy of the gap detection data of the hydraulic valve assembly and avoiding the poor actual use effect of the hydraulic valve assembly due to the insufficient accuracy of the gap detection data of the hydraulic valve assembly when the detection tool is in use.

[0039] The pressure valve device 7 also includes four vertical blocks 75, two horizontal strips 76 and two arc-shaped heat insulation boards 77. The four vertical blocks 75 are fixed to the front and back surfaces of the two U-shaped plates 72 in groups of two, the two horizontal strips 76 are fixed to the top surfaces of the four vertical blocks 75, and the two arc-shaped heat insulation boards 77 are fixed to the top surfaces of the two horizontal strips 76. The two arc-shaped heat insulation boards 77 are respectively located above the two rubber rollers 74. The arc-shaped heat insulation boards 77 block the warm light tube 64 from irradiating the rubber roller 74, so that the rubber roller 74 will not be irradiated by the warm light tube 64, and avoid the rubber roller 74 being irradiated by the warm light tube 64 when the detection tool is in use, causing rapid aging and damage to the rubber roller 74.

[0040] While the support rod 121 drives the spring rod 122 to move toward the middle, the spring rod 122 drives the L-shaped plate 61 to move toward the middle, the L-shaped plate 61 drives the triangular block 62 to move toward the middle, the triangular block 62 drives the square shell 63 to move toward the middle, and the square shell 63 drives the warm light tube 64 to move toward the middle. Since the hydraulic valve assembly is made of metal and has the physical property of thermal expansion and contraction, the warm light tube 64 is started in the process of the warm light tube 64 moving toward the middle, and the warm light tube 64 shines on the top of the hydraulic valve assembly, and the hydraulic valve assembly begins to heat up, allowing the detection tooling to simulate the outdoor high temperature environment for gap detection, thereby preventing the equipment from failing to detect the pressure resistance of the hydraulic valve assembly gap in a high temperature environment when in use, thereby avoiding the problem of poor equipment detection effect caused by the detection tooling failing to detect the pressure resistance of the hydraulic valve assembly gap in a high temperature environment.

[0041] While the spring rod 122 drives the L-shaped plate 61 to move toward the middle, the L-shaped plate 61 drives the connecting block 65 to move toward the middle, and the connecting block 65 drives the double-ring rod 66 to move toward the middle. The double-ring rod 66 slides toward the middle on the thin rod 67, so that when the L-shaped plate 61 moves toward the middle, the double-ring rod 66 restricts the L-shaped plate 61, so that the L-shaped plate 61 will not vibrate violently during the movement toward the middle, thereby preventing the L-shaped plate 61 from vibrating violently when the equipment is in use, thereby avoiding the problem of the warm light tube 64 being easily damaged due to the violent vibration of the L-shaped plate 61 when the detection tooling is in use.

[0042] When the locking cam 72 is in the closed position, the locking cam 74 is in the closed position, and the locking cam 74 is in the closed position, so that the locking cam 74 is in the closed position and the locking cam 74 is in the closed position.

[0043] While the oblique rod 71 drives the U-shaped plate 72 to rotate upward, the U-shaped plate 72 drives the vertical block 75 to rotate upward, the vertical block 75 drives the horizontal plate 76 to rotate upward, and the horizontal plate 76 drives the arc-shaped heat insulation plate 77 to rotate upward, so that the arc-shaped heat insulation plate 77 blocks the warm light tube 64 from irradiating to the rubber roller 74, so that the rubber roller 74 will not be irradiated by the warm light tube 64, thereby preventing the rubber roller 74 from being irradiated by the warm light tube 64 when the equipment is in use, thereby avoiding the problem of rapid aging and damage of the rubber roller 74 caused by the warm light tube 64 when the inspection tooling is in use.

[0044] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
