[0020] See also Figure 1-4

[0021] Embodiment 1: A special measuring tool for a sleeve ball gauge rod comprises a tool body 1, wherein two circular grooves 2 are symmetrically provided on the surfaces of the left and right sides of the tool body 1, and circular openings 3 are provided at the upper ends of the inner walls of the circular grooves 2. Pins 4 of different lengths are inserted into the circular grooves 2 on the tool body 1, and fastening screws 5 are inserted into the circular openings 3, and the bottom ends of the fastening screws 5 are in conflict with the pins 4.

[0022] The gauge body 1 is made of high-strength aviation aluminum alloy.

[0023] Embodiment 2: The difference between this embodiment and embodiment 1 is that the diameter of the middle part of the two circular grooves 2 is 12.7 mm.

[0024] Embodiment 3: The difference between this embodiment and embodiment 1 is that the pin rod 4 is made of mold steel, the diameter of the pin rod 4 is 12.65 mm, and the end of the pin rod 4 is inserted into the circular groove 2.

[0025] This allows the pin 4 to be inserted into the circular groove 2 more snugly.

[0026] Embodiment 4: The difference between this embodiment and embodiment 1 is that the surfaces of the gauge body 1 and the pin rod 4 are relatively smooth.

[0027] It makes it more convenient for the user to take the gauge body 1 and the pin rod 4, and the surfaces of the gauge body 1 and the pin rod 4 are processed by removing burrs and turning sharp edges into blunt edges.

[0028] In this embodiment, since most of the traditional ring grooves are on the surface of the product, they can be measured by ball gauges, scales, three-coordinate measuring methods, etc. However, for some ring grooves that have other product structures in the middle and cause interference, conventional means cannot be used for measurement, and are not conducive to mass production, which has a great impact on product processing, thereby resulting in low efficiency in ring groove measurement and affecting the product qualification rate.

[0029] In summary, in specific implementation, when the user needs to measure some ring groove products, the user first needs to check whether the device has any impact problems during use, and the gauge body 1 and the pin rod 4 can be set with a variety of mutually compatible components with different models and diameters, and then used to measure ring grooves of different models.

[0030] During actual measurement, the user first selects the corresponding different models of the gauge body 1 and the pin rod 4, places the product in the gauge body 1, and pushes the pin rod 4 in the circular groove 2 so that the end of the pin rod 4 can extend to the surface of the product and then contact the side of the annular groove. Then, by rotating the fastening screw 5, the fastening screw 5 moves downward in the circular opening 3, and then can contact and fix the surface of the pin rod 4 pushed in the circular groove 2, so that the pin rod 4 is firmly fixed on the gauge body 1, and can contact the product annular groove more stably, so that the required measured annular groove data can be obtained conveniently and quickly.

[0031] Moreover, the gauge body 1 and the pin rod 4 of the product can reduce energy loss and improve work efficiency by using different structures and material designs. At the same time, the usage is simple, which improves product quality, processing efficiency and testing efficiency, and has no impact on the environment and safety. It is suitable for various working environments. Through the gauge body 1 and the pin rod 4, the circular groove 2 is opened to reduce the weight of the body without affecting the measurement of the coaxiality of the flow channel hole. The pin rod 4 of the gauge body 1 is used to perform interference annular groove measurement, which is simple and convenient. The gauge body 1 has the characteristics of high strength and light weight, which is convenient for users to operate.
