Description

Inclined target ball seat

Technical Field

The utility model belongs to the technical field of the metallurgical measurement, in particular to inclined target ball seat.

Background

Due to the limitation of the steel rolling process of a steel rolling mill, the working environment of the steel rolling mill is poor, and negative factors including high temperature, dust, oil stain, noise, radiation and the like have negative effects on field rolling mill equipment and workers. High temperature and high humidity generated at any moment in the steel rolling process inevitably cause corrosion, abrasion and impact on a rolling mill frame, particularly a window body, an upper roller and a lower roller, so that the spatial positions of all parts of the rolling mill are changed. The rolling precision of the rolling mill is closely related to the spatial positions of various components of the rolling mill. Once the spatial positions of the window of the rolling mill and the internal rollers are displaced relatively, the specification of the finally rolled and formed steel cannot meet the specified requirement.

In order to monitor and adjust and recover the working accuracy of the rolling mill, the relative position of the rolling mill window and the inner roll system needs to be detected by laser, and the position is adjusted according to the detected relative position deviation so as to recover the original design value. The detection method is that a target ball is fixed at the position of a rolling mill to be detected, then a laser tracker emits a laser beam to the target ball, and at the moment, a triangular prism in the target ball receives the laser beam, so that the absolute distance between two points can be accurately measured. The position or reference point measurement by using a laser tracker is a commonly used method in the metallurgical industry, and a plurality of documents are provided for the measurement system and the principle of the method. There are also commercially available target balls for use with laser trackers. For example, Leica Geosystems provides a target ball that is a metal ball fitted with a triangular reflector to ensure a constant offset when measuring a surface.

During detection, the floor height of a whole set of rolling mills reaches 50-60 meters, and the whole set of rolling mills is divided into floors, and each floor has respective equipment to be detected. The goal of detection is to ascertain the spatial position of each tier of equipment relative to the overall equipment. In this case, a coordinate system suitable for each floor device must be constructed for the entire device, i.e., a unified coordinate system. Then the laser tracker is respectively transferred to each floor, and the laser tracker is enabled to identify the new position of the laser tracker in the originally established unified coordinate system by collecting the detection points arranged before as the common points, so that the equipment of the floor is further detected. This step, commonly known as "transfer," is the key to detecting an elevated and sub-floor facility. The success of the transfer station depends on the common point, namely whether the arranged detection points can be successfully tracked by the laser trackers in front of and behind the transfer station under the condition of keeping the common point still. The common point is arranged in the middle of the laser tracker before and after the transfer station. No matter how the target ball fixed on the traditional target ball seat rotates, the prism surface of the target ball can only receive the laser beam sent out from the target ball seat, and the back surface of the target ball is a blind receiving area. And the laser tracker after the station is changed is just in the receiving blind area of the target ball, so that the tracker cannot re-identify the unified coordinate system, and the station changing failure is caused.

SUMMERY OF THE UTILITY MODEL

Detailed Description

In accordance with one or more embodiments, as shown in fig. 1 and 2, an angled target tee, the target tee comprising: base, base magnet, target ball support column and target ball magnet. The base is a cylinder with one end presenting an inclined plane; the base magnet is embedded in the inclined end of the base; one end surface of the target ball supporting column is connected with the other end surface of the base cylinder; the target ball magnet is embedded and arranged inside the other end face of the target ball supporting column, so that the target ball supporting column is used for sucking and fixing the target ball. The axial angle between the oblique end surface of the base cylinder and the base cylinder may be 45 °.

Further, in accordance with one or more embodiments, the 45 ° angled backing plate comprises a cylindrical base of aluminum alloy. The base is provided with a target ball supporting cylinder with a slightly smaller diameter, a magnet block is arranged in the target ball supporting cylinder, and the end part of the target ball supporting cylinder is fixed by the attraction force of the magnet. The base is a cylinder with a slightly larger diameter, the bottom of the base is inclined at an angle of 45 degrees after being turned, and meanwhile, a round magnet block is screwed in by a screw and is used for being adsorbed on the plane of the rolling mill equipment. After the point selection is finished, the target ball is fixed at one end of the 45-degree inclined target ball seat, and then the inclined plane at the other end of the target ball seat is fixed on the plane of the rolling mill equipment through the attraction force of the magnet. A layer of silica gel can be applied to the base of the end portion by a glue gun for reinforcement.

Because the bottom adopts the special structure of a 45-degree inclined plane, and the length of the cylinder of the target ball seat can ensure that the rotating range of the target ball placed at the end part is not limited to the plane attached to the bottom of the target ball seat any more. The target ball can rotate more flexibly, so that the range of the target ball for receiving the laser beam is enlarged, the defect that a back receiving blind area exists in a traditional target ball seat is overcome, and the laser beam emitted by a laser tracker which moves to a high place after a station is transferred is smoothly received.

The application of the 45-degree inclined target ball seat in practical detection is exemplified as follows:

as shown in fig. 3. The laser tracker is first placed at earth level, facing the device under test. Detection points are then placed at various floors of the apparatus. The laser tracker uniformly records the distribution points at a tracking angle of upward view, thereby establishing a uniform coordinate system. The laser tracker that is transferred to each floor then re-tracks the detection point that was previously placed at that floor in the top view. Because the inclined target ball seat with the angle of 45 degrees is used in the detection points, the rotation angle of the target ball is enlarged, and the range of the target ball for receiving the laser beam is enlarged. Although the tracking angle is changed from a bottom view to a top view, the target ball fixed on the 45-degree inclined target ball seat can still smoothly receive the laser beam, so that the station is turned, and the next floor equipment is specifically detected.

In conclusion, the inclined target ball seats of 45 degrees play an irreplaceable role in equipment detection of the floors with higher heights and three-dimensional coordinate system transfer of each floor.

It is worth noting that while the foregoing has described the spirit and principles of the present invention with reference to several specific embodiments, it is to be understood that the present invention is not limited to the disclosed embodiments, nor is the division of aspects, which is for convenience only as the features in these aspects cannot be combined. The invention is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
