Description

Technical Field

[0001] The utility model relates to the technical field of gas-liquid separator detection equipment, in particular to a position detection tool for a gas-liquid separator. Background Art

[0002] The gas-liquid separator is an important component arranged between the evaporator and the compressor, which can separate the gas from the liquid, thereby preventing the liquid refrigerant from entering the compressor. The structure of the gas-liquid separator is relatively complex, and it is often necessary to detect the position of the holes on the surface of the gas-liquid separator. As shown in the Chinese utility model "A Position Gauge for the Holes of an Engine Oil-Gas Separator" with patent number CN201320215506.5 (authorization announcement number CN203177768U), the gauge includes a base plate and a detection pin. A positioning hole is provided on the base plate at a position corresponding to the hole to be measured on the workpiece, and the detection pin is inserted into the positioning hole. The detection pin is a cylindrical structure, and its size matches the hole to be measured on the workpiece. Whether the detection pin can be inserted into the hole to be measured can be used to determine whether the hole to be measured on the workpiece meets the standard size.

[0003] Although the above position gauge can quickly detect whether the hole to be tested meets the standard size, if the part to be tested is Figure 1The gas-liquid separator shown in the figure presents another detection problem. The gas-liquid separator includes a tank body 1′ and a cover body 2′ disposed above the tank body 1′, wherein the upper surface of the cover body 2′ at least partially protrudes upward along the axial direction of the tank body 1′ to form a mounting portion 3′, and the side wall 31′ of the mounting portion 3′ has an inlet 4′ disposed perpendicularly to the axial direction of the tank body 1′ and mounting holes 5′ symmetrically disposed on both sides of the inlet 4′. The gas-liquid separator is fixed between the evaporator and the compressor through the two mounting holes 5′. Since the installation position of the gas-liquid separator is usually fixed, the distance between the two mounting holes 5′ needs to be within a preset range (i.e., position accuracy). If the position and distance of the two mounting holes 5′ are not within the preset range, the gas-liquid separator installation process will be difficult, the installation effect will be unstable, or even impossible to install, and thus the two mounting holes 5′ need to be detected for position accuracy. If the above-mentioned position gauge is used to detect the position of the two mounting holes 5', the tank body 1' needs to be placed horizontally on the bottom plate. However, the tank body 1' is a cylinder, and the outer wall of the tank body 1' may be provided with a plurality of parts for subsequent installation, which results in the tank body 1' being unable to be placed horizontally and stably on the bottom plate, and further results in the above-mentioned position gauge for the two mounting holes 5' being detected inaccurately. In addition, the existing gas-liquid separator gauge usually uses a clamping device to fix the product stably on the gauge. The clamping device clamps the side wall 31' of the mounting portion 3'. However, when the thickness of the side wall 31' of the mounting portion 3' is small, if the clamping device does not correspond to the position of the detection pin in the clamped state, it is easy to cause the side wall 31' of the mounting portion 3' to deform, thereby affecting the subsequent processing and use of the gas-liquid separator. For this reason, it is necessary to make further improvements to the position gauge of the gas-liquid separator. Summary of the invention
