Description

Y-shaped target ball seat

Technical Field

The utility model belongs to the technical field of metallurgical measurement, in particular to Y formula 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.

In the detection, it is sometimes necessary to detect the roll body of the roll and evaluate the change in position of the roll body with respect to the center line of the rolling mill facility. At this time, a detection person needs to hold the target ball to be tightly attached to the roller body so as to receive the laser beam emitted by the laser tracker, and detection of each point on the roller body is completed. This detection method has two drawbacks: the roller is a cylinder, the surface of the roller body is arc-shaped, and the target ball is a sphere. The two surfaces are contacted by arc-shaped objects, so that the phenomenon of slipping is very easy to occur. The stability of the target ball is difficult to guarantee only by a fixing mode that a detector holds the target ball by hand, so that the detection precision is influenced; secondly, because the working condition of steel rolling production field is abominable, the temperature is higher, and the palm of the hand of detection personnel perspires easily, leads to the target ball to follow the landing in the hand. And the field device is often stained with dust and oil stains, and the target ball is stained by hands, so that the target ball is polluted, and the detection precision is reduced.

SUMMERY OF THE UTILITY MODEL

The embodiment of the utility model provides a Y formula target ball seat for solve in rolling mill parameter measurement, current target ball seat is difficult to the difficult problem with the laminating of roll surface steadily.

The embodiment of the utility model provides an one of, a Y formula target ball seat, this target ball seat includes:

a cylindrical base;

a magnet embedded inside one end surface of the cylindrical base;

the Y-shaped head comprises a Y-shaped fork and a Y-shaped fork handle, and is a hoe with the Y-shaped fork, the Y-shaped fork is fixed at one end of the Y-shaped fork handle, and the other end of the Y-shaped fork handle is connected with the other end face of the cylindrical base.

The utility model discloses to the difficult problem that meets in actual detection, provide a Y formula target ball seat, to a great extent has improved the actual problem that is difficult to effectively fix the target ball that often meets in present laser detection, has really realized three big characteristics of accuracy, high efficiency, the safety that laser detected.

Detailed Description

In accordance with one or more embodiments, as shown in fig. 1 and 2, a y-shaped target tee, the target tee comprising: cylinder base, magnet and Y shape head. The magnet is embedded inside one end face of the cylindrical base. The end face is a spherical curved surface, and the radius of the spherical curved surface is consistent with the radius of the target ball, so that the end face of the cylindrical base can attract and fix the target ball through magnetic force. The radius of this spherical surface can be chosen to be 19.05mm, depending on the size of the target sphere at hand. The surface roughness of the spherical curved surface can be Ra 0.2-1.2 μm, and the same roundness of any circumference of the curved surface is less than or equal to 0.01 mm. After the target ball is placed on the target ball seat, the distance between the lowest point of the target ball surface and the magnet is recommended to be controlled to be 0.6-1.55 mm, so that the moderate magnetic force is ensured.

Further, in accordance with one or more embodiments, the Y-head target tee is constructed from two pieces, a Y-head and a cylindrical base. The Y-shaped head is made of polymer composite materials, one end of the Y-shaped head is a Y-shaped fork, and the other end of the Y-shaped head is provided with a threaded column. The Y-shaped head is screwed into the cylindrical base made of aluminum alloy through the threaded column, and therefore the two parts are fixedly combined. This configuration is adopted. Accord with human hand mechanics principle, the Y head is held to detection personnel's of being convenient for finger, simultaneously because the Y head has 2 simultaneously and rolls the curved surface contact, ensures that whole target ball seat is stable to be placed on the roll surface, and the target ball is fixed at cylinder base terminal surface by the interior magnet actuation of base, ensures that the target ball also can be stable actuation in target ball seat tip under the prerequisite of hugging closely the roll shaft, ensures that the target ball of pressing from both sides between Y head target ball seat and roll surface can receive the laser beam that laser tracker sent smoothly. Fig. 3 is a schematic diagram of the manner in which the target ball holder is used.

The embodiment avoids the unstable problem caused by directly holding the target ball by hand through the auxiliary detection tool of the Y-shaped head target ball seat, ensures the detection precision and simultaneously plays a good role in protecting the target ball. The Y-shaped head target ball seat can well solve the problem of detecting the roll surface of the roll, ensures the detection precision, also protects the detection device of the target ball, and is an irreplaceable auxiliary detection tool in the detection of the type.

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.
