Description

Technical Field

[0001] The invention belongs to the technical field of hydraulic valve detection, and in particular relates to an automatic detection device for a hydraulic valve. Background Art

[0002] A hydraulic valve is an automated component operated by pressurized oil. It is controlled by the pressure oil of a pressure regulating valve and is usually used in combination with an electromagnetic pressure regulating valve. It can be used to remotely control the on / off of oil, gas, and water pipeline systems in hydropower stations. Therefore, it is widely used in various mechanical fields. Hydraulic valve detection can detect potential problems through detection, and timely maintenance and repair can avoid further deterioration of the problem, thereby extending the service life of the hydraulic valve.

[0003] Hydraulic valves need to be disassembled during maintenance, and the disassembled parts need to be placed on the disassembly and assembly test bench. Oil often leaks from hydraulic valve parts, resulting in a large amount of oil remaining on the disassembly test bench. For hydraulic valve parts with high oil content, if they are not degreased before measurement, the high oil content may reduce the mechanical properties of the valve body material, such as hardness, compression strength, and yield strength. In addition, if the oil is not completely evaporated, pores or cracks will be formed, further weakening the mechanical properties of the material. On the other hand, density testing is an important means to evaluate the density and quality of materials. High oil content will cause the test results to deviate from the expected values.

[0004] Therefore, a hydraulic valve automatic detection device is designed to solve the above problems. Summary of the invention

[0030] Working principle: First, place the hydraulic valve component to be tested in the degreasing solvent cylinder 4 for immersion and degreasing. After degreasing, transfer the component to the overflow water tank 3 to prepare for density detection. The overflow water tank 3 is filled with water. When the hydraulic valve component is placed in, the water level will rise due to the drainage effect of the component. The overflow trough 12, overflow pipe 13 and water collecting cover 14 on the outside of the overflow water tank 3 are responsible for collecting and measuring this part of the overflowed water, so as to calculate the density of the component. The ultrasonic bubble sensor 16 is installed on the placement table 15 to detect whether there are bubbles in the water to ensure that there is no residual grease on the surface of the component that affects the density test result. The X-axis sliding table 2 is driven by the servo motor 17 and drives the positioning component 5 back and forth along the top of the detection table 1 through the transmission of the conveying shaft 18, the synchronous belt 19 and the pulley 20. The DC motor 52 in the movement and positioning component 5 drives the rotating hollow frame 54 to rotate through the connecting shaft 53, thereby driving the performance detection component 6 and the rotating clamping component 7 installed on the rotating hollow frame 54 to rotate to the specified position. The pressure sensor 22 on the outside of the limit frame 66 pressurizes the hydraulic valve component to simulate the actual working conditions. During operation, the hydraulic cylinder 61 can drive the rack 65 to slide on the flip base 62, and then the locking gear 64 and the flip shaft 63 are engaged and driven to realize the flipping and angle adjustment of the flip frame and the pressure sensor 22 outside it. During the pressurization process, the strain sensor 67 monitors the strain of the component to evaluate its anti-deformation ability. The reduction motor 73 in the rotating clamping component 7 drives the connecting arm 75 and the clamping arm 76 to rotate through the transmission shaft 74, thereby clamping the components in the overflow water tank 3. The mechanism composed of the asynchronous motor 8 and the hollow support arm 9 allows the rotating clamping assembly 7 to further rotate on the rotating hollow frame 54 to achieve mechanical flipping of the component. After completing all the detection steps, the servo motor 17 can be started, and the synchronous belt 19 completes the transmission effect under the same speed rotation of the two sets of pulleys 20, and cooperates with the meshing internal pressure seat 21, so that the upper X-axis sliding table 2 drives the clamped component to move and put it back to the specified position.
