Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. It is to be understood that the embodiments described are merely exemplary of the invention and are not intended to be exhaustive. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Example (b):

the utility model provides a pair of some devices are got in laser tracker target ball location for the definite of reference line 3 when cooperation laser tracker 4 is to production line equipment fixing or production line equipment maintenance, as shown in figure 1 and figure 2, some devices are got in laser tracker 4 target ball location includes base 1 and target ball 2. Be equipped with blind hole 101 on the terminal surface of base 1 one end, target ball 2 demountable installation is in the port department of blind hole 101, is equipped with three prisms 201 on the target ball 2 and is used for the reflection laser.

Specifically, as shown in fig. 2, the base 1 includes a base side wall and a base bottom plate, the base bottom plate is circular, the base side wall encloses the blind hole 101 formed on the base bottom plate, the base 1 is provided with a chamfering structure 102 connected with the blind hole 101, and the target ball 2 is placed on the chamfering structure 102 so as to stabilize the position of the target ball 2. The end surface of the base 1, which is not provided with the blind hole 101, is provided with a through hole 103 coaxial with the blind hole 101. By providing the through hole 103, after the reference line 3 is determined, the positioning hole 110 is left right below the reference line 3 at both ends of the production line by passing an auxiliary tool through the through hole 103. It should be noted that, the diameter of the through hole 103 is 2mm, and an excessively large diameter of the through hole 103 may cause an error in placement of the base 1 during the later maintenance, because after the positioning hole 110 is determined by the excessively large through hole 103, the center point of the through hole 103 and the center point of the positioning hole 110 cannot be accurately aligned during the later maintenance.

As shown in fig. 2, four evenly distributed direction scales 104 are arranged on the periphery of the end surface of the base 1 provided with the blind hole 101, and an included angle between any two direction scales 104 is 90 degrees. The direction scales 104 are provided in four, on one hand, for the sake of beauty, and on the other hand, for the sake of easy observation, after the susceptor 1 is oriented by the first boss 109, the irradiation direction of the laser light is further accurately determined by aligning the direction scales 104 with the laser light. Wherein, a bubble 108 and a first boss 109 are arranged between two direction scales 104, and evenly distributed angle scales 105 are arranged between any two other direction scales 104. When the laser tracker 4 target ball 2 positioning and point taking device is used, the levelness of the base 1 is quickly adjusted by observing the bubbles 108, so that the leveling time is saved.

It should be noted that the direction scale 104 may also be configured as a compass, and is not an implementation.

In practice, due to the manufacturing error of the base 1, when the reference line 3 is re-determined for the production line equipment maintenance, the orientation of the base 1 is changed every time, and different relative position coordinates of the target ball 2 and the laser tracker 4 are obtained, such as: and measuring the same positioning hole 110, measuring once, and re-measuring by rotating the base 1 to obtain different relative position coordinates of the target ball 2 and the laser tracker 4, so that the determined reference line 3 is inaccurate. Therefore, the orientation of the susceptor 1 facing the laser irradiation at the measurement point is recorded by the designed first boss 109 and the direction scale 104 and angle scale 105 to avoid an error caused by the orientation change of the susceptor 1 when the reference line 3 is re-determined.

It should be noted that, when maintaining the production line equipment, the base 1 is placed on the positioning hole 110, and the alignment relationship between the through hole 103 and the positioning hole 110 is directly observed, so that the position of the base 1 can be determined more quickly and accurately compared with the prior art.

As shown in fig. 1 and 2, four second bosses 106 are uniformly connected to the side wall of the base 1, threaded holes 1061 are formed in the second bosses 106, and each threaded hole 1061 is provided with an adjusting bolt 107. After the base 1 is leveled by the blister 108, the adjusting bolt 107 is adjusted to maintain the base 1 in a horizontal position so that the positioning hole 110 is marked through the through hole 103 using an auxiliary tool. Of course, the leveling adjustment assembly includes, but is not limited to, the above-mentioned manner, and an adjustment screw or the like may be provided on the end surface of the base 1 on which the through hole 103 is provided, and the embodiment is not limited thereto.

For understanding the utility model discloses, as shown in fig. 3, provide the utility model discloses confirm reference line 3's schematic diagram, laser tracker 4 sends laser to target ball 2 central point, and target ball 2 passes through prism 201 reflection laser to laser tracker 4, determines target ball 2 and laser tracker 4's relative spatial position, connects the central point between two target balls 2, determines reference line 3, and of course, reference line 3 is a virtual line.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all should be covered within the protection scope of the present invention.
