Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of laser trackers, in particular to a mounting base of a target ball of a laser tracker. BACKGROUND

[0002] The laser tracker detection technology has been widely used in the installation and maintenance construction of large-scale equipment in steel plants. The laser tracker can significantly improve the precision and efficiency of equipment installation and maintenance through high-precision measurement and real-time tracking capability. In the process of using the laser tracker, the setting of the reference point is one of the key links. At present, the commonly used reference point installation methods include hot melt adhesive bonding and welding.

[0003] The hot melt adhesive bonding target ball base is bonded to the surface of the equipment by a hot melt glue gun. At least 20 minutes of hot melt glue heating process is required before bonding, which is time-consuming. At least 15 minutes is required to wait for the hot melt glue to solidify after bonding the target ball base. The hot melt glue is an elastic material, and the hot melt glue under the base is prone to deformation during the placement and removal of the target ball, resulting in errors in point reading data. Welding is to weld the metal base on the equipment body. The construction area needs to be powered and connected to the welding machine for construction, which takes a long time to prepare and requires a dedicated person to assist in welding. The target ball base after welding cannot be reused, which increases the use cost. It cannot meet the conditions of rapid and efficient, portable and firm at the same time. CONTENT OF THE INVENTION

[0030] The first positioning member 100 is used for fixing in a measurement area, the first positioning member 100 is provided with a first through hole 101 in the center, one side of the first positioning member 100 is provided with a sunken groove 102, and the sunken groove 102 is communicated at one end of the first through hole 101;

[0031] As Figure 1 , Figure 2 indicated, the first positioning member 100 is the basic part of the mounting base and is used for fixing on the surface of the equipment in the measurement area. The first positioning member 100 is provided with a first through hole 101 in the center position, and the first through hole 101 penetrates the upper and lower surfaces of the first positioning member 100 and is used for accommodating the connecting component for fixing the first positioning member 100.

[0032] As Figure 1 , Figure 2 indicated, the first positioning member 100 is the basic part of the mounting base and is used for fixing on the surface of the equipment in the measurement area. The first positioning member 100 is provided with a first through hole 101 in the center position, and the first through hole 101 penetrates the upper and lower surfaces of the first positioning member 100 and is used for accommodating the connecting component for fixing the first positioning member 100.

[0033] The bottom of the first positioning member 100 is provided with a structure for fixing on the measuring area. For example, a threaded hole can be used to fix the first positioning member 100 on the surface of the equipment by a screw; or a magnetic material can be used to enable the first positioning member 100 to be adsorbed on the surface of the metal equipment. In addition, a structure can also be configured to cooperate with a pneumatic nail gun to firmly fix the first positioning member 100 on the measuring area by a pneumatic nail.

[0034] As shown in Figure 1 , Figure 2 The second positioning member 200 is detachably connected to the first positioning member 100, and the second positioning member 200 is provided with a containing space 202 for containing a target ball.

[0035] The second positioning member 200 is an upper structure of a mounting base for containing a target ball of a laser tracker. The top of the second positioning member 200 is provided with a containing space 202 which is matched in shape and size with the target ball for stably containing the target ball. The containing space 202 can be designed as a spherical groove or a cylindrical groove, and the target ball can be closely embedded therein to ensure that the target ball will not be loose or displaced during the measurement process.

[0036] The bottom of the second positioning member 200 is provided with a connecting structure matched with the sunken groove 102 of the first positioning member 100. For example, a buckle structure is used to quickly install and detach the second positioning member 200.

[0037] In actual operation, the first positioning member 100 can be placed on the surface of the equipment in the measuring area, and a suitable fixing method is selected according to the material and condition of the surface of the equipment. If the surface of the equipment is made of metal material, the first positioning member 100 can be adsorbed and fixed by using a magnetic material; if a more firm fixation is needed, a screw can be used to fasten the first positioning member 100 on the surface of the equipment through the threaded hole at the bottom of the first positioning member 100; or a pneumatic nail gun can be used to pass a pneumatic nail through the fixing structure of the first positioning member 100 to firmly nail the first positioning member 100 on the surface of the equipment.

[0038] Then, the second positioning member 200 is installed on the first positioning member 100 according to the adopted connecting method. The target ball of the laser tracker is placed in the containing space 202 of the second positioning member 200 to ensure that the target ball is matched with the containing space 202 so that the target ball is accurately positioned at the predetermined position.

[0039] During the measurement process of the laser tracker, if it is needed to adjust the position of the target ball, the second positioning member 200 can be detached and moved to the first positioning member 100 at other position together with the target ball. Since the second positioning member 200 is detachably connected with the first positioning member 100, the operation is convenient and fast, and the adjustment can be quickly completed without affecting the measurement progress.

[0040] The mounting base in the application is applied to the installation and positioning of a laser tracker target ball, and the operation principle of the mounting base is that the mounting base comprises a first positioning member 100 and a second positioning member 200, the first positioning member 100 is used for being fixed in a measurement area, a first through hole 101 is arranged at the center of the first positioning member 100, a sunken groove 102 is arranged on one side of the first positioning member 100, and the sunken groove 102 is communicated with one end of the first through hole 101; and the second positioning member 200 is detachably connected to the first positioning member 100, and a containing space 202 for containing the target ball is arranged on the second positioning member 200.

The first positioning member 100 is fixed in the measurement area by a mechanical mode, compared with the bonding mode of the hot melt adhesive, the mechanical fixation is more firm, and the position of the reference point will not be deviated due to the elastic deformation of the hot melt adhesive. Compared with the welding mode, the mounting base can be repeatedly disassembled and reinstalled, and the base or the surface of the equipment will not be damaged due to welding, thereby reducing the use cost. The hot melt adhesive gun, welding machine and other equipment do not need to be carried, thereby reducing the equipment demand and preparation work of the construction area.

[0042] The design of the first through hole 101 and the sunken groove 102 can ensure the accurate installation position of the target ball, avoid the deviation of the reference point caused by the deformation of the hot melt adhesive or the welding error, and improve the measurement accuracy of the laser tracker. The detachable connection mode of the second positioning member 200 facilitates the adjustment and replacement of the target ball, and further ensures the accuracy of the measurement. It is suitable for different measurement areas and equipment surfaces, and is not limited by the bonding conditions (such as temperature and surface cleanliness) of the hot melt adhesive or the welding conditions (such as power supply and welding equipment availability). Without the need for special personnel to cooperate with welding or long time waiting for the solidification of the hot melt adhesive, the labor input and time cost in the construction process are reduced.
