The structure is simple, the operation is convenient, and the guide block measurement and positioning work is effectively completed.
[0024] In a preferred embodiment, the length of the connecting piece is equal to the vertical design distance value between the center point of the U-shaped seat in the design drawing and the center point of the lower ear axis of the zero-segment fan-shaped segment in contact with the guide block. The connecting piece 1.3 is used to make the axes of the U-shaped seat dummy shaft 1.1 and the guide block dummy shaft 1.2 in the same plane. It has a simple structure and is easy to use. It can ensure that the relative position of the U-shaped seat dummy shaft 1.1 and the guide block dummy shaft 1.2 is the same as the relative position of the U-shaped seat and the guide block, thereby ensuring the accuracy of the measurement.
[0025] In a preferred embodiment, the U-shaped seat dummy shaft 1.1 includes a U-shaped seat main shaft, a first U-shaped seat measuring shaft 1.1.1 and a second U-shaped seat measuring shaft 1.1.2. The first U-shaped seat measuring shaft 1.1.1 and the second U-shaped seat measuring shaft 1.1.2 are integrally formed at both ends of the U-shaped seat main shaft.

[0028] The utility model is a measuring tool for a zero-stage guide block of a continuous casting machine, the tool 1 comprises: a U-shaped seat dummy shaft 1.1, a guide block dummy shaft 1.2 and a connecting piece 1.3. The device is made of stainless steel and other materials with low surface roughness, sufficient rigidity and light weight.
[0029] The tooling 1 is mainly used to cooperate with the laser tracker to measure the positional relationship between the zero-section guide block 4 of the continuous casting machine and the U-shaped seat 2. Before measurement, the U-shaped seat 2 must be adjusted to the standard state by adding or removing gaskets on the base 3. During measurement, the U-shaped seat dummy shaft 1.1 must be placed on the U-shaped seat 2, wherein the first U-shaped seat measuring shaft 1.1.1 (the second U-shaped seat measuring shaft 1.1.2) sits on the right U-shaped seat 2.1 (the left U-shaped seat 2.2), so the first U-shaped seat measuring shaft 1.1.1 and the second U-shaped seat measuring shaft 1.1.2 have high machining accuracy requirements, especially the four indicators of coaxiality, roughness, cylindricity and diameter deviation.

In order to ensure that the tooling 1 is in a natural drooping state along the vertical direction during measurement, the diameters of the first guide block measuring axis 1.2.1 and the second guide block measuring axis 1.2.2 are designed to be 10mm smaller than the design distance between the left (right) side fixed side guide block and the 4.2 left (right) side loose side guide block 4.4. Similarly, the first guide block measuring axis 1.2.1 and the second guide block measuring axis 1.2.2 have high machining accuracy requirements, especially the four indicators of coaxiality, roughness, cylindricity and diameter deviation.
[0031] The connecting piece 1.3 is a rectangular parallelepiped, including: right rectangular parallelepiped 1.3.1 and left rectangular parallelepiped 1.3.2. The length of the connecting pieces 1.3 on both sides [i.e. the vertical distance between the center of the right (left 1.1.2) side U-shaped seat dummy shaft measuring part 1.1.1 and the center of the right (left 1.2.2) side guide block dummy shaft measuring part 1.2.1] should be equal to the vertical design distance value between the center point of the U-shaped seat 2 in the design drawing and the center point of the lower ear shaft of the zero-segment sector contacting the guide block 4. The connecting piece 1.3 should ensure that the axes of the U-shaped seat dummy shaft 1.1 and the guide block dummy shaft 1.2 are in the same plane.
[0032] After the measurement is completed with the laser tracker, the guide block is restored to the design value by adding or removing the adjustment shims 6 between the guide block and the movable support 5 according to the measured value.
