Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of industrial measurement, in particular to a large-scale equipment reference point used in conjunction with a laser tracker. Background Art
[0002] At present, reference points are also reserved when processing large equipment. These reference points are mainly used in machine tool processing and cannot be used with laser trackers. Moreover, these reference points are usually exposed to the air, and the references will be inaccurate after long-term corrosion. At present, many studies on laser tracker reference points have been conducted in China, but there has been no relevant research on reserving reference points on the main body of large equipment, such as: a target ball seat for measuring with a laser tracker and a layout device for ground control points of laser trackers and total stations. These two reference points can only be welded or bonded to the equipment when in use or when the equipment is installed, which not only easily affects the accuracy of the equipment, but the reference points themselves are prone to change or fall off from the equipment body. There is also a wall control point layout device for laser trackers. This kind of reference point can only be embedded in the wall and cannot be reserved for use on the main body of large equipment.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] The purpose of the utility model is to provide a large-scale equipment reference point used in conjunction with a laser tracker to solve the problems existing in the above-mentioned prior art, effectively avoid corrosion of the reference point, and effectively improve measurement accuracy.
[0023] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0024] The utility model provides a large equipment reference point used in conjunction with a laser tracker, such as Figures 1 to 4 As shown, it includes: a reference hole 2 and a cover 8. The reference hole 2 is integrally processed on the device 1 and the top surface of the reference hole 2 is flush with the surface of the device 1. The reference hole 2 is used to cooperate with the target ball of the laser tracker for positioning; the cover 8 is used to be fixedly connected to the reference hole 2 so as to be detachable and washable to seal the reference hole 2. By arranging the reference hole 2 and the device 1 as one, the device 1 or the reference point is synchronously sunk or deformed, which effectively reduces the error. In addition, by arranging the cover 8 to seal the reference hole 2, corrosion of the reference point is effectively avoided, and the measurement accuracy is further improved.
[0025] In a preferred embodiment, the reference hole 2 is provided with an internal thread, and the cover 8 is provided with an external thread 6. The cover 8 is used for threaded connection with the reference hole 2, has a simple structure, is convenient to connect, and can seal the reference hole 2.
[0026] In a preferred embodiment, it also includes a cover opening hole 7, which is fixedly connected to the top of the cover 8. The cover opening hole 7 is used in conjunction with an inner angle wrench to open or close the cover 8. The cover opening hole 7 is an inner four-corner or inner hexagonal wrench, with a simple structure and easy operation. The cover 8 can be opened by an inner hexagon or inner four-corner wrench.
[0027] In a preferred embodiment, a contact surface 3 is provided in the reference hole 2, and the contact surface 3 is used to place a target ball of a laser tracker.
[0028] In a preferred embodiment, a lubricating oil layer is provided on the contact surface 3, and the lubricating oil is applied to the contact surface 3. Since the reference point is used less frequently, a proper amount of lubricating oil is applied to the surface of the contact surface 3 to prevent the reference point from rusting.
[0029] In a preferred embodiment, it also includes a dust collection hole 4, which is arranged below the contact surface 3 and has a distance from the laser tracker target ball placed on the contact surface 3.
