It includes a support platform, a base plate 1 mounted on the support platform, a guide structure on the base plate 1, a product fixing plate 2 that can move left and right along the guide structure, and a right fixing plate 3 located to the right of the base plate 1 on the guide structure. The product fixing plate 2 has a positioning hole 5, and a detachable product positioning block 6 is located on the side of the product fixing plate 2 opposite to the right fixing plate 3. The product positioning block 6 has a probe mounting hole 7 that matches the positioning hole 5. A dial indicator 8 is mounted on the right fixing plate 3, with its measuring rod 9 positioned along the X-axis. The head of the measuring rod 9 of the dial indicator 8 faces the probe mounting hole 7. The device also includes a height standard block that can be placed and removed. The height standard block includes a fixing part 10 and a column part 11. The fixing part 10 matches the side wall of the product positioning block 6 opposite to the right fixing plate 3. The column part 11 can be placed inside the probe mounting hole 7 with a clearance fit. The length of the column part 11 matches the standard height of the probe to be measured. The product positioning block 6 and the product fixing plate 2 are fixedly connected by bolts. The column part 11 is adapted to the measuring rod 9 of the dial indicator 8. Support bosses are provided at the four corners of the bottom of the support platform.

[0020] The guiding structure includes a left fixing seat 4 located on the left side of the upper end face of the base plate 1. Two guide posts 12 are arranged parallel to each other along the X-axis between the left fixing seat 4 and the right fixing plate 3. Each guide post 12 is provided with a linear guide sleeve 13. The lower part of the product fixing plate 2 is provided with a guide sleeve fitting hole that matches the linear guide sleeve 13. The base plate 1 is also provided with a limiting block 14, which is arranged along the X-axis. The limiting block 14 has a strip hole 15 extending along the X-axis. The lower part of the outer wall of the product fixing plate 2 facing the limiting block 14 has a limiting hole 16 that matches the strip hole 15. A side locking bolt is provided between the strip hole 15 and the limiting hole 16.

[0021] The guide structure includes a linear slide rail set on the base plate 1 along the X-axis direction, and a slider with locking function is set on the linear slide rail. The bottom of the product fixing plate 2 is set on the slider.

[0022] The upper part of the right fixed plate 3 is provided with an assembly through hole 17 that is compatible with the measuring rod 9 of the dial indicator 8. The top end face of the right fixed plate 3 is provided with an upper positioning through hole 18 that communicates with the assembly through hole 17. An upper locking bolt is provided in the upper positioning through hole 18, and the bottom of the upper locking bolt is connected to the side wall of the measuring rod 9 of the dial indicator 8.

[0023] A set of height standard blocks is provided, and the length of the standard height column of each standard height block is adapted to the length of the probe to be measured of different lengths.

[0024] Place the height standard block into the probe mounting hole 7. The cylindrical part 11 of the height standard block is located inside the probe mounting hole 7. The fixing part 10 and the side wall of the product positioning block 6 are in contact. The product fixing plate 2 moves so that the cylindrical part 11 and the head of the dial indicator 8 measuring rod 9 are in contact. The dial indicator 8 measuring rod 9 is retracted. The retraction length is greater than the tolerance range of the height of the probe to be measured specified in the drawing. The dial indicator 8 is zeroed and the position of the product fixing plate 2 is locked, completing the initial setting.

[0025] Then, remove the height standard block. The measuring rod 9 of dial indicator 8 will spring back, and the reading on dial indicator 8 will be negative. Install the probe to be tested into the probe mounting hole 7. If the height of the probe to be tested is exactly the same as the height standard block, the reading on dial indicator 8 should be 0. If they are not the same, the value read by dial indicator 8 is the positive or negative tolerance of the probe to be tested. Of course, if the negative deviation of the probe size is too large, and it cannot even make contact with dial indicator 8, and the reading on dial indicator 8 does not change, then it is directly judged as unqualified.
