Description

Technical Field

[0001] This utility model relates to the technical field of valve component processing equipment, specifically to a continuous testing device for valve component processing with clamping function. Background Technology

[0002] A valve is a device used in a fluid system to control the direction, pressure, and flow rate of a fluid. It enables or stops the flow of media within piping and equipment and controls its flow rate. Valves are control components in fluid transport systems, possessing functions such as shut-off, regulation, flow guidance, backflow prevention, pressure stabilization, diversion, or overflow pressure relief. They can be used to control the flow of various types of fluids, including air, water, steam, various corrosive media, mud, oil, liquid metals, and radioactive media. Therefore, the use of valves requires a testing device. Valve assembly appearance inspection equipment is an important tool to ensure the quality of valve assemblies. These devices are mainly used to check the surface quality, dimensional accuracy, and presence of defects in valve assemblies.

[0003] Existing valve component processing and testing equipment lacks a self-moving clamping structure. For example, a general-purpose valve testing device disclosed in application number CN202223240345.3 often requires manual or external mechanical intervention to move and position the valve components. This not only increases operational complexity but may also lead to a significant reduction in processing efficiency. In contrast, equipment with a self-moving clamping structure can automatically complete clamping, moving, and positioning actions, thereby significantly improving processing efficiency. Equipment without a self-moving clamping structure requires operators to possess higher skills and technical expertise to manually move and position the valve components, which not only increases operational complexity but may also lead to operational errors and safety hazards. A self-moving clamping structure simplifies the operation process, reduces operational difficulty, and thus improves the safety and reliability of the production line. For valve components of different specifications and sizes, equipment without a self-moving clamping structure may require changing different clamps or adjusting equipment parameters to adapt, which not only increases the complexity and cost of the equipment but may also limit its flexibility.

[0004] Therefore, it is necessary to invent a continuous inspection device for valve assembly processing with clamping function to solve the above problems. Utility Model Content

[0016] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

An inspection camera 202 is fixedly mounted on the bottom of the mounting base 201, with the lens end of the inspection camera 202 facing downwards. Side frames 3 are located in the center of both sides of the outer wall of the work frame 1, and a fixed seat 4 is installed in the center of the inner side of the side frame 3. A movable plate 5 is installed above the center of the fixed seat 4. The moving plate 5 and the fixed base 4 have a moving groove 401 in the middle of their top surfaces. A reciprocating screw 402 is installed in the middle of the moving groove 401. The reciprocating screw 402 passes through the middle of the lower end of the moving plate 5. Auxiliary sliding grooves 403 are provided on both sides of the surface of the fixed base 4. An auxiliary slider 404 is installed in the middle of the auxiliary sliding groove 403. The top surface of the auxiliary slider 404 is fixedly connected to both sides of the bottom surface of the moving plate 5. A connecting rod 501 is fixed in the middle of the front wall of the moving plate 5. The output end of the connecting rod 501 is connected to the middle of the rear wall of the chuck 6.

[0028] Guide rods 502 are inserted through the two upper corners of the movable plate 5. One end of the guide rod 502 is fixedly connected to the upper inner side of the side frame 3. A clamp 6 is provided on the front side of the movable plate 5. The two clamps 6 are rectangular. Infrared transmitters 601 are installed on both the upper and lower sides of the clamping surface of one clamp 6. A gasket 602 is installed in the middle of the clamping surface of both clamps 6. Infrared receivers 603 are installed on both the upper and lower sides of the clamping surface of the other clamp 6. The infrared transmitters 601 and infrared receivers 602... 3 is a non-contact wireless connection. The infrared transmitter 601 emits infrared rays through its internal infrared light source, which correspond to the infrared receiver 603 at the corresponding position, and forms an infrared straight line between the corresponding infrared transmitter 601 and infrared receiver 603. The lower plate 7 is fixedly installed on the middle of both sides of the outer wall of the top seat 2. A conveyor frame 8 is set between the two fixed seats 4. The conveyor frame 8 is located above the middle of the work frame 1. A feeding plate 9 is inclinedly set on one side of the conveyor frame 8, and a feeding plate 10 is set on the other side of the conveyor frame 8.

[0029] The infrared transmitter 601, infrared receiver 603 and detection camera 202 mentioned above are all existing technology products, and their specific structures and functions will not be described in detail here.

[0030] The working principle of this practical application is as follows:

[0031] Refer to the instruction manual appendix Figure 1-5For this type of continuous inspection equipment for valve assembly processing with clamping function, during use, the work frame 1 first supports the overall structure and provides the inspection platform. The top seat 2 is equipped with an inspection camera 202 for visual inspection. The side frame 3 supports the fixed seat 4 and the moving plate 5. The fixed seat 4 has a built-in reciprocating screw 402 that drives the moving plate 5 to move laterally. The moving plate 5 drives the chuck 6 to perform clamping action. The chuck 6 is used to clamp the valve assembly and is equipped with an infrared transmitter 601 and a receiver 603 for non-contact inspection. The conveyor frame 8 transports the valve assembly to be inspected. The unloading plate 9 and the discharge plate 10 are used for unloading and sorting of unqualified or qualified products, respectively. The valve assembly to be inspected is transported by the conveyor frame 8 to a position directly below the inspection camera 202. The reciprocating screw 402 drives the moving plate 5 to move along the guide rod 502, so that the two chucks 6 on both sides close and clamp the workpiece. The auxiliary slider 404 slides in the auxiliary slide groove 403 to ensure smooth movement. The infrared transmitter 601 on one side of the chuck emits infrared light, and the infrared receiver on the other side emits infrared light. The infrared transmitter 601 receives signals and emits infrared rays through its internal infrared light source, which correspond to the infrared receiver 603 at the corresponding position, forming an infrared straight line between the infrared transmitter 601 and the infrared receiver 603. There is no need for a physical connection between the infrared transmitter 601 and the infrared receiver 603. When the infrared rays are blocked from passing through the object to be detected, the infrared sensor 601 will emit an electrical signal. This electrical signal is transmitted to the control system. The control system determines whether the object has passed through according to the preset program and issues a clamping command. The clamping command is transmitted to the clamping mechanism, which drives the clamping component to move and clamp the object. Then, the detection camera 202 at the bottom of the top seat 2 takes a picture of the clamped valve assembly. The image analysis detects surface defects such as scratches, deformation, or assembly accuracy such as hole position misalignment. This continuous detection equipment for valve assembly processing with clamping function has the advantages of compact structure, simple operation, high processing accuracy, and high degree of automation.
