[0023] See also Figure 1-4

[0024] Embodiment 1: A JIC PORT special measuring fixture comprises a fixture body 1, on which a pin rod, a workpiece flow channel hole and a middle cavity hole are provided, a circular groove 2 is provided at the lower end of the fixture body 1, a circular measuring head 3 is arranged at the lower end of the inner wall of the circular groove 2, a setting block 4 is arranged on the circular measuring head 3 at the bottom of the fixture body 1, a reserved hole is arranged at the top of the fixture body 1, a dial 5 is arranged at the top of the fixture body 1, and the dial 5 is fixedly connected to the fixture body 1 by a fastening screw 6.

[0025] The gauge body 1 is made of aviation aluminum alloy.

[0026] A protective pad is provided on the inner wall of the reserved hole provided on the top of the gauge body 1 .

[0027] Embodiment 2: The difference between this embodiment and embodiment 1 is that the side wall of the circular groove 2 is hollow.

[0028] By providing the circular groove 2 in a hollow shape, the overall weight of the gauge body 1 can be reduced.

[0029] Embodiment 3: The difference between this embodiment and embodiment 1 is that the setting block 4 is made of die steel.

[0030] The setting block 4 can be reused multiple times.

[0031] Embodiment 4: The difference between this embodiment and embodiment 1 is that the surfaces of the gauge body 1 and the setting block 4 are smooth.

[0032] The connection between the gauge body 1 and the setting block 4 is made smoother, and the surfaces of the gauge body 1 and the setting block 4 are both deburred and sharpened.

[0033] In this embodiment, since most of the current traditional positioning methods can only use three-coordinate measurement, the measurement method is complicated and inefficient, and it cannot be measured during the processing process, which is not conducive to mass production and has a great impact on product processing. In view of the existence of the above reasons, it causes low work efficiency and affects the product qualification rate.

[0034] In summary, in specific implementation, when using this device, it should be checked whether there are any problems that affect the use of the device. This gauge can adapt to different models to measure different types of JIC PORT dimensions by replacing the diameter of the circular measuring head 3 and the diameter depth of the setting block 4. When the dial 5 is in use, it can be set with a variety of different sizes of model categories according to the user's measurement needs, and the connection between the dial 5 and the gauge body 1 can be disassembled, so that it can adapt to the measurement of end face cone holes of different sizes.

[0035] In actual use, the user first places the gauge body 1 and the workpiece at the same ambient temperature to reduce the time for balancing the temperature during measurement, thereby effectively improving work efficiency. The user then holds the gauge body 1 with both hands through the gauge body 1 and steadily moves the gauge body 1 to the block 4 to be set. The circular measuring head 3 is aligned with the setting block 4 and steadily lowered to avoid bumps and scratches. When the user touches the bottom of the gauge body 1, the pointer on the dial 5 shakes. The gauge body 1 should sink again and fit completely with the setting block 4 without shaking, and the upper end surface should be level with the setting block 4. Finally, the user adjusts the dial 5 to zero.

[0036] Then the user takes out the gauge body 1 again, moves the gauge body 1 steadily to the part to be tested on the product, aims the circular measuring head 3 at the product and puts it down steadily to avoid bumps and scratches. When the user touches the gauge body 1 to the bottom again, the pointer of the dial 5 shakes. The gauge body 1 should sink again and fit the product completely without shaking, and the upper end surface should be level with the product. Finally, the user records the data and obtains the measurement result by comparing the zero deviation of the data.

[0037] The gauge body 1 of the device is made of high-strength aviation aluminum alloy, so that the gauge body 1 has high wear resistance and can reduce component loss. The circular groove 2 is set in a hollow shape, which not only reduces the overall weight of the gauge body 1, but also does not affect the measurement of the valve body position. The JIC PORT size of the product is measured through the dial 5 on the gauge body 1, which is simple and convenient. The gauge body 1 has the characteristics of high strength and light weight, which is easy for users to operate.
