The manual measurement efficiency of the inspector is extremely low and it is easy to produce measurement errors, resulting in losses in production. The outer circle of the pressure plate is where the sealing ring is used for sealing, such as Figure 1 As shown, once the size deviates, it will affect the use of the sealing ring and cause gas leakage.

[0018] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0019] like Figures 1 to 4 As shown, the utility model provides a tool for quickly measuring the outer circle size of a pressure plate of an automobile air-conditioning pipeline, comprising a measuring block 10. The measuring block 10 is a cylindrical structure. A first measuring hole 11 with a first preset depth is vertically opened downward at the top center of the measuring block 10, and a second measuring hole 12 with a second preset depth is vertically opened upward at the bottom center of the measuring block 10; the diameter of the first measuring hole 11 is greater than or equal to the diameter of the outer circle 20 of the pressure plate, and the diameter of the second measuring hole 12 is smaller than the diameter of the outer circle 20 of the pressure plate.
[0020] like Figure 4 As shown, when the utility model is used, the measuring block 10 is placed upright on a horizontal platform, and the outer circle 20 of the pressing plate is first placed in the first measuring hole 11. If the outer circle 20 of the pressing plate can be placed in the first measuring hole 11 of the measuring block 10, the measuring block 10 is then placed upside down on the horizontal platform, and the outer circle 20 of the pressing plate is then placed in the second measuring hole 12. If the outer circle 20 of the pressing plate cannot be placed in the second measuring hole 12 of the measuring block 10, it is a qualified product. On the contrary, if the outer circle 20 of the pressing plate cannot be placed in the first measuring hole 11 or can be placed in the second measuring hole 12, the pressing plate is an unqualified product.
[0021] As an optimization solution of the utility model, Figure 2 and Figure 3 As shown, the first preset depth and the second preset depth should be greater than the length of the pressure plate joint so as to fully accommodate the pressure plate joint.
[0022] As an optimization solution of the utility model, Figure 2 and Figure 3 As shown, the outer edges of the top and bottom surfaces of the measuring block 10 are chamfered. The chamfered structure of the outer edges can prevent the staff from getting scratched when taking the measuring block 10.
[0023] As an optimization solution of the utility model, Figure 2 and Figure 3 As shown, the outer edge between the first measuring hole 11 and the measuring block 10 and the outer edge between the second measuring hole 12 and the measuring block 10 are both chamfered. The chamfered structure of the first measuring hole 11 and the second measuring hole 12 can prevent the outer circle 20 of the pressing plate from being damaged when being placed in the first measuring hole 11 and the second measuring hole 12.
[0024] As an optimization solution of the utility model, Figure 2 and Figure 3As shown, the first measuring hole 11 and the second measuring hole 12 are connected to each other, and an annular transition groove is provided between the first measuring hole 11 and the second measuring hole 12.
[0025] As an optimization solution of the utility model, the measuring block 10 is made of GCr15. GCr15 steel is a representative steel type of high carbon chromium bearing steel with good comprehensive performance. The measuring block 10 made of GCr15 has high hardness and is durable. At the same time, the heat treatment adopts isothermal quenching, which can ensure the stability of the tool.
[0026] As an embodiment of the utility model, the diameter of the first measuring hole 11 is 15.45 mm. The diameter of the second measuring hole 12 is 15.32 mm. In this case, the pressing plate with the outer diameter 20 of the pressing plate of 15.45 to 15.33 mm can be screened relatively accurately. This effectively solves the problem of low efficiency and easy measurement error in the prior art of manually measuring the outer diameter of the pressing plate of the automobile air conditioning pipeline.
[0027] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
