Referring to fig. 2 to 3, the present embodiment provides an auxiliary detection structure for assembly accuracy of a sector basic frame, wherein the sector basic frame includes a first frame 1 and a second frame 2, the first frame 1 is used for assembling a first planar base 11 and a first U-shaped base 12, the second frame 2 is used for assembling a second planar base 21 and a second U-shaped base 22, a connection column 3 is disposed between the first frame 1 and the second frame 2, and two ends of the connection column 3 are respectively connected to the first frame 1 and the second frame 2. The second frame 2 is provided with a first reference hole 4, a second reference hole 5 and a third reference hole 6, the first reference hole 4 and the second reference hole 5 are sequentially located below the second U-shaped seat 22, and the central points of the first reference hole 4 and the second reference hole 5 are located on a vertical line of the connecting column 3 close to the central point of the end part of the second frame 2. The third reference hole 6 is located below the second plane seat 21, and the vertical height of the center point of the third reference hole 6 is the same as that of the center point of the first reference hole 4. Similarly, the first frame 1 is provided with a first reference hole 4, a second reference hole 5 and a third reference hole 6, the first reference hole 4 and the second reference hole 5 are sequentially located below the first U-shaped seat 12, and the center points of the first reference hole 4 and the second reference hole 5 are located on the vertical line of the connecting column 3 close to the center point of the end of the first frame 1. The third reference hole 6 is located below the first plane seat 11, and the vertical height of the center point of the third reference hole 6 is the same as that of the center point of the first reference hole 4. Reference pins are assembled inside the first reference hole 4, the second reference hole 5 and the third reference hole 6, and the diameters of the reference pins are the same as the diameters of the first plane seat 11 fixing pin, the second plane seat 21 fixing pin, the first U-shaped seat 12 fixing pin or the second U-shaped seat 22 fixing pin.
It should be noted that the specific structure of the basic frame of the segment is not limited in this embodiment, and it is based on the conventional device structure of the segment of the continuous casting machine in the art, wherein the first frame 1 and the second frame 2 are completely mirror-image arranged, and the plane seat and the U-shaped seat respectively assembled on the first frame 1 and the second frame 2 are firmly connected by the fastening pin.

In this embodiment, the reference pin and the fixed pin are cylindrical pins, so that on one hand, point positioning is performed on the deviation displacement measurement, and on the other hand, acting forces in all directions of the cylindrical pins are the same, which is beneficial to supporting each reference hole. Specifically, when the fitting offset amount is detected, the leveling rule is used to abut on each of the reference pins as point contact, that is, the leveling rule and the reference pins constitute point positioning. Meanwhile, the fixing pin is generally arranged to be cylindrical, so that stress on each part is balanced, and supporting capacity is enhanced.
In this embodiment, the length of the reference pin is greater than the depths of the first reference hole, the second reference hole and the third reference hole, so that the reference pin partially extends out of each reference hole, and point positioning is conveniently performed by using a flat ruler.
In this embodiment, the material of the reference pin is a wear-resistant alloy, preferably a copper-tin alloy, so as to prevent the reference pin from causing a positioning error due to wear.
Taking the orientation shown in fig. 3 as an example, the working principle or using method of the embodiment is as follows: after the fan-shaped section foundation frame is assembled, the flat ruler is leaned on the right outer diameter of the reference pin assembled in the first reference hole 4 and the second reference hole 5, the upper end of the flat ruler is close to the second U-shaped seat fastening pin 220, and if the right outer diameter of the second U-shaped seat fastening pin 220 exceeds the flat ruler, the assembly is deviated to the right.

If there is a distance between the right outer diameter of the second clevis fastening pin 220 and the flat rule, the assembly is shifted to the left, the feeler gauge is used to detect the leftward shift, and a gasket is added to the left side of the second clevis fastening pin 220 according to the shift, and a gasket group having the same thickness is reduced to the right side of the second clevis fastening pin 220, thereby completing the detection and adjustment of the assembly accuracy of the second clevis 22 on the second frame 2. After the second U-shaped seat 22 is assembled, the distance between the cylindrical pin in the first reference hole 4 and the fastening pin of the second U-shaped seat is measured by using a caliper, then the distance is used as a distance standard, the position of the fastening pin 210 of the second plane seat is vertically determined from the cylindrical pin in the third reference hole 6, and the accurate assembly of the second plane seat 21 is completed. The accurate assembly of the first base frame 1 is detected and determined by the same method, after the first base frame 1 is assembled, the standard shaft is placed on the first U-shaped seat 12 and the second U-shaped seat 22, the distance between the standard shaft and the same side of the two second reference holes is measured by a micrometer, the coaxiality is in accordance with the design if the distances on the two sides are the same, the distance values are different, the gasket is required to be adjusted according to the values to enable the coaxiality to be in accordance with the design, and then the detection and adjustment of the key size of the sector base frame are completed.
