Description

Technical Field

[0001] The utility model relates to the technical field of detection jigs, in particular to a hole detection jig for an automotive copper valve. Background Art

[0002] Automotive copper valves are important components used in the automotive industry and are widely used in various fluid control systems, such as cooling systems, fuel systems, braking systems, etc. Copper valves are widely used due to their excellent corrosion resistance, thermal conductivity, and machinability. Their main function is to control the flow of liquids or gases by opening and closing the valve, thereby ensuring the normal operation of various automotive systems. The quality of copper valves is directly related to the performance and safety of the vehicle. Therefore, it is particularly important to carry out strict quality control during the manufacturing process. During the production of automotive copper valves, the accuracy of the internal hole diameter of the valve directly affects its sealing performance and service life. An oversized or undersized hole diameter will cause the valve to be unable to effectively control the flow of the fluid, thereby affecting the operation of the entire system. For example, if the hole diameter is too large, it may cause leakage of liquids or gases; if the hole diameter is too small, it may result in insufficient flow rate, affecting the normal operation of the system. Therefore, after the production of copper valves is completed, strict hole diameter detection must be carried out to ensure that it meets the design requirements and quality standards, thereby ensuring the consistency and reliability of the product. To achieve this goal, a jig is required when detecting the holes of automotive copper valves to fix the position of the automotive copper valve during detection and ensure the accuracy and efficiency of detection.

[0003] The patent with the publication number CN219996149U discloses a hole detection jig for a brass valve, which includes a pressing cylinder, a rotator, and a jig base. There are two sets of rotators, which are symmetrically installed on the jig base, one on the left and the other on the right. There are two sets of pressing cylinders, which are symmetrically installed on the rotators. It also includes a valve pressing block and a valve fixator. The valve pressing block is installed at the front end of the pressing cylinder, and the valve is clamped between two symmetrical valve pressing blocks. One side of the valve pressing block that is in contact with the side wall of the valve has an inner groove shape that conforms to the outer wall of the valve. The valve fixator is installed on the jig base and is located at the symmetry axis position of the two valve pressing blocks, and is used to press the valve so that the valve port is directly below the electric hole detection head. This jig can complete the hole detection work of the three valve ports of the valve in one clamping, reducing the number of clampings and improving the detection efficiency.

[0004] Although the above-mentioned prior art can clamp and position the copper valve and turn the copper valve, the shape of the valve pressing block is fixed and cannot be adjusted and replaced according to copper valves of different shapes and specifications. There may be a situation where the contact surface between the valve pressing block and the copper valve is very small, resulting in unstable clamping. This design limits the versatility and adaptability of the fixture. Moreover, the cooperation of two sets of rotators and two pressing cylinders is required to realize the turning and fixing of the valve, and the structure is relatively complex with many components, increasing the manufacturing and maintenance costs of the equipment. In view of this, we propose a hole detection fixture for automotive copper valves. Summary of the Invention
