Description

Technical Field

[0001] The utility model belongs to the technical field of continuous casting machine detection, and in particular relates to a special continuous casting machine U-shaped seat measuring tool matched with a target ball of a laser tracker. Background Art

[0002] In the prior art, when measuring the U-shaped seat of the continuous casting machine support frame, a sample shaft is required for measurement. Most of the dummy shafts currently used are heavy and very inconvenient to carry. In addition, a target ball is required to collect a large number of measurement points at both ends of the dummy shaft to fit the center coordinate position of the U-shaped seat, which results in a large workload.

[0003] The prior art discloses a slab continuous casting machine fan-shaped support measurement and reading tool, which belongs to the field of continuous casting machine arc detection technology. The device includes three parts: a through shaft, a cylindrical seat, and a positioning shaft head. The through shaft, the cylindrical seat, and the positioning shaft head are integrally processed, the positioning shaft heads are located at both ends of the through shaft, and the cylindrical seat is located outside the two ends of the positioning shaft head. The through shaft, the cylindrical seat, and the positioning shaft head are designed as concentric arcs. The advantage is that the detection position accuracy can be improved to 0.01mm, and the original method has about 8-10 data collection points for a single dummy shaft. Using the slab continuous casting machine fan-shaped support measurement and reading tool of the present design, the single dummy shaft data collection point can be reduced to 2 times. The tooling improves the detection problem of the center coordinate of the fan-shaped support of the continuous casting machine, but the method of positioning the axis position by a single point is very easy to cause measurement errors, and there is no means to verify the accuracy of the measurement results. This method effectively solves the problem of large workload of using traditional dummy shaft measurement, but its weight is large, and its shaft head position is easy to deform, and it is not easy to find after deformation, which is easy to cause maintenance accidents.

[0004] The prior art discloses a continuous casting machine fan-shaped support measuring tool, which belongs to the field of continuous casting machine arc detection technology. The device includes three parts: a positioning boss, a detection hole, and a positioning flange. The positioning boss, the detection hole and the positioning flange are processed as a whole, the positioning flange is located at the upper part of the positioning boss, and the detection hole is located at the center of the positioning flange and the positioning boss, and penetrates the positioning flange and the positioning boss. The advantage is that it solves the problem of inaccurate detection data such as large numerical deviations of detection and fitting due to the difficulty of close contact between the spherical prism and the detection surface during direct detection and the detection points are not in the same cross section. The main problem of this method is that the tooling does not contact the bottom of the U-shaped seat, and cannot reflect the actual situation of the fan-shaped segment being located on the support frame.

[0005] The prior art discloses a measuring tool for the basic frame of a continuous casting machine segment, which includes a laser tracker, a zero segment upper sample shaft, a zero segment lower sample shaft, and a segment sample shaft with coaxial measuring wheels at both ends, wherein the zero segment upper sample shaft and the zero segment lower sample shaft are respectively installed in the zero segment upper U-shaped support and the zero segment lower U-shaped support of the segment basic frame; the two measuring wheels of the segment sample shaft lean against a group of positioning plates of the segment basic frame; the laser tracker is fixed to the basic frame of the segment end through the tracker base, and the target mirror of the laser tracker is placed on the zero segment upper sample shaft, the zero segment lower sample shaft or the segment sample shaft. The measurement workload of this false shaft is large.

[0006] In view of the above factors, a special U-seat measuring tool for continuous casting machine is designed to cooperate with the laser tracker target ball. The target ball is placed on four bases to cooperate with the laser tracker to complete the detection of the U-seat position. Its characteristics are light weight and easy to carry. The detection work can be completed by detecting the positions of the four bases, and the workload is less than the traditional false axis measurement method. Utility Model Content

[0030] like Figure 1-3 As shown, a U-shaped seat measuring tool for a continuous casting machine specially used for a target ball of a laser tracker comprises a support frame U-shaped seat 1 and a main shaft 2 arranged between the support frame U-shaped seat 1, wherein the support frame U-shaped seat 1 is divided into a first U-shaped seat 1-1 and a second U-shaped seat 1-2, and the left and right sides of the main shaft 2 are respectively connected to the end shaft 3, and the end shaft 3 comprises a first end shaft 3-1 and a second end shaft 3-2, and the support frame U-shaped seat 1 cooperates with the end shaft 3;

[0031] A base 4 is disposed at intervals on the top of the main shaft 2 , and a target ball 5 is installed on the base 4 for cooperation with a laser tracker for detection.

[0032] In order to facilitate the handling of the device in use and to reduce the weight of the device to the maximum extent while ensuring the structural strength, the main shaft 2 and the end shaft 3 are made of metal material, which is aluminum alloy.

[0033] In order to avoid affecting the range of the target ball receiving the laser beam emitted by the laser tracker during use, the top of the main shaft 2 is made into a convex arc structure, and the outer diameter of the main shaft 2 is larger than the diameter of the end shaft 3.

[0034] In order to improve the matching accuracy when in use, the first end shaft 3-1 and the second end shaft 3-2 are semicircular, and the cylindricity and roughness of the cylindrical surface meet the accuracy requirements for measuring the U-shaped seat of the continuous casting machine.

[0035] Four bases 4 are arranged at intervals on the top of the main shaft 2, and along the axial direction of the main shaft 2 from right to left, there are four bases: a right base 4-1, a middle right base 4-2, a middle left base 4-3, and a left base 4-4;

[0036] The middle right base 4-2 and the middle left base 4-3 are used to check the overall straightness;

[0037] The right base 4 - 1 and the left base 4 - 4 are used to reflect the position coordinates of the U-shaped base 1 of the supporting frame.

[0038] In order to facilitate use without affecting the measurement accuracy, the right base 4-1 and the left base 4-4 are close to the first U-shaped seat 1-1 and the second U-shaped seat 1-2, and the distance between the right base 4-1 and the left base 4-4 and the first U-shaped seat 1-1 and the second U-shaped seat 1-2 is 4-10mm.

[0039] The right base 4-1, the middle right base 4-2, the middle left base 4-3, and the left base 4-4 are all provided with a target ball 5;

[0040] After the target balls 5 are placed on the four bases of the right base 4-1, the middle right base 4-2, the middle left base 4-3, and the left base 4-4, the center points of the four target balls 5 all pass through the line connecting the center points of the first end axis 3-1 and the second end axis 3-2.

[0041] In order to facilitate the fixing of the target ball 5 in the use state and the rotation of the target ball 5 during detection so as to rotate a trace of dust into the dust collection hole, the base 4 includes a contact surface 4A, a notch 4B, a dust collection hole 4C and a magnet block 4D. The contact surface 4A is an arc-shaped notch that matches the target ball 5, so the diameter of the contact surface 4A is the same as the diameter of the target ball 5. The bottom of the base 4 is provided with a dust collection hole 4C, and a magnet block 4D is also provided in the base 4.

[0042] A notch 4B is provided on one side of the detection end of the base 4, and the notch 4B is an arc-shaped notch.

[0043] The utility model is a U-shaped seat measuring tool for continuous casting machine used in conjunction with a laser tracker target ball, comprising a main shaft 2, an end shaft 3, and a base 4. The device is made of aluminum alloy and other materials with low surface roughness and sufficient rigidity and lightness. In order to make it as convenient as possible to carry and place, the weight of the device is reduced to the maximum extent under the premise of ensuring structural strength.

[0044] Among them, the outer diameter of the main shaft 2 is larger than that of the end shaft 3. The top of the main shaft 2 is made into a convex arc shape to increase the light receiving range of the target ball without affecting the range of the target ball receiving the laser beam emitted by the laser tracker.

[0045] The left and right sides of the main shaft 2 are connected to the end shaft 3 respectively. The end shaft 3 is semicircular, and the cylindricality and roughness of its cylindrical surface must meet the accuracy requirements for measuring the U-shaped seat of the continuous casting machine. The end shaft 3 is used in conjunction with the U-shaped seat 1 of the continuous casting machine support frame. When testing, the end shaft 3 is placed on the U-shaped seat 1 of the continuous casting machine support frame. After confirming that the two are in close contact, the next step of testing can be carried out.

[0046] There are four bases on the top of the spindle, from right to left, they are the right base, the middle right base, the middle left base, and the left base. All four bases must be inspected during testing. The middle right base and the middle left base are used to check whether the overall straightness of the tooling meets the requirements, and the right base and the left base are used to reflect the position coordinates of the U-shaped seat. The base is used to place the target ball for detection with the laser tracker, so the base is a precision machined part. After placing the target ball on the right base, the middle right base, the middle left base, and the left base, the center points of the four target balls pass through the line connecting the center points of the right end shaft and the left end shaft, which reflects the position relationship between the first U-shaped seat and the second U-shaped seat. Among them, the right base (left base) should be as close to the first U-shaped seat (second U-shaped seat) on the right as possible, otherwise it will affect the measurement accuracy.

[0047] The four bases, namely the right base 4-1, the middle right base 4-2, the middle left base 4-3 and the left base 4-4, have the same structure. The bases include four parts: a contact surface, a notch, a dust collection hole and a magnet block. The contact surface is the main component. Its main purpose is to place the target ball on the contact surface during detection. Therefore, the diameter of the contact surface is the same as that of the inch target ball, and the contact surface is a precision machined surface. In order to prevent dust from causing a decrease in the accuracy of the contact surface, a dust collection hole is set at the bottom of the base to facilitate cleaning. In addition, when the target ball is rotated during detection, a trace amount of dust can be turned into the dust collection hole. A magnet block is set at the bottom of the dust collection hole to ensure that the target ball is in close contact with the contact surface and does not fall off. A notch is set at the detection end of the base to increase the light receiving range of the target ball.
