Abstract

The utility model relates to a laser tracker coordinate setting auxiliary device for a large curved surface, belonging to laser tracking technology. The device comprises a mounting seat formed by an upper cover (4), a lower seat (6), a locating rod (7) and a horizontal press rod (5), wherein the bottom of the lower seat (6) is provided with a vertical center hole, and the two opposite sides of the lower seat are provided with symmetrical vertical guide grooves (10); the lower end of the locating rod (7) is in a cone shape, the lower part of the locating rod is installed inside a vertical center hole (8) of a base, and the upper part thereof is supported on the base by a spring (9); the horizontal press rod (5) is arranged inside a horizontal through hole at the upper part of the locating rod (7) and extends out of the vertical guide grooves (10); and the upper cover is provided with vertical center hole (3) which is internally provided with magnet (2) used for attracting a target ball (1). The device can realize the functions of converting and marking navigation coordinate of a laser interferometer so as to locate a target point on the curved surface, thus improving the accuracy and the rapidity in locating and marking the coordinate.

Description

Be used for large-scale curved coordinate positioning auxiliary device for laser tracker
Technical field
The utility model be used for laser tracker on large-scale curved surface the servicing unit during enterprising row-coordinate location.
Background technology
The principle of work of laser tracker is by the prism on the target ball the former road of laser beam to be returned, and direction that penetrates according to laser and laser starting point calculate the coordinate figure of target ball position to the distance of target ball center.The laser tracker measurement range is big, and the precision height can be used for the check of big molded dimension and the processing and the installing and locating of equipment.Laser tracker can also carry out navigator fix according to the CAD digital model, and this need of work is the coordinate figure and the positioning error of given impact point earlier.Running target ball during the location provides cue until the laser tracker prompting when the front target ball position has been positioned at the positioning error scope of permission.This moment, target ball sphere center position was the given coordinate points of cad model.For having on the actual curved surface of cad model mark coordinate points accurately and rapidly, need a location and installation seat with coordinate conversion and mark function.
Summary of the invention
The purpose of this utility model provides a kind of large-scale curved coordinate positioning auxiliary device for laser tracker that is used for, and is convenient to running target ball position searching target point position, can get mark ready after searching impact point on curved surface.
A kind ofly be used for large-scale curved coordinate positioning auxiliary device for laser tracker, it is characterized in that:
Comprise by loam cake and following the mount pad of forming;
Above-mentioned following bottom has vertical center pit, the vertical direction recess that following seat two relative sides have symmetry; One lower end is that the backstay bottom of taper is installed in the vertical center pit of base, and top is supported on the base by spring; One horizontal struts is installed in the horizontal through hole on backstay top, and stretches out from above-mentioned vertical direction recess;
Above-mentioned loam cake has vertical center pit, is provided with the magnet that is used to hold the target ball in the vertical center pit of this loam cake.
Conical bore is processed at center, mount pad upper surface, the target ball is placed on the conical bore target ball center and mount pad dead in line.In the middle of the mount pad magnet is set, firm the holding of target ball can be able to not be become flexible.Taper is processed in the backstay lower end, is used for marking point on curved surface.Backstay supports with spring, and normal condition backstay lower end awl point is positioned at mount pad inside fully.Depress with the fixed depression bar of backstay can drive backstay along Surface Method to extruding a very little round dot.Processing column hole, mount pad lower end, with the backstay clearance fit, backstay moves up and down along cylindrical pilot hole.Processing gathering sill in the middle of the mount pad, thin bar moves up and down along gathering sill.Mount pad is divided into upper end cover and base two parts, links to each other with sunk screw.Upper end cover and base are processed boss and groove respectively, guarantee to install the conical bore of back upper end cover and the right alignment in base guide hole.Backstay, spring, depression bar and magnet are packed into behind the mount pad, tighten the installation that sunk screw is finished the location and installation seat.
The utility model can be realized conversion of laser interferometer navigation coordinate and mark function, the location of finishing impact point on the curved surface, the accuracy and the rapidity of raising coordinate setting mark.
Description of drawings
Fig. 1 is a three-view diagram of the present utility model.
Fig. 2 is an overall schematic of the present utility model.
Number in the figure title: 1, target ball, 2, magnet, 3, the vertical center pit of loam cake, 5, horizontal struts, 6, following, 7, backstay, 8, the vertical center pit of base, 9, spring, 10, vertical direction recess.
Embodiment
This location and installation seat is suitable for the large-scale curved localizing objects point of going up.The target ball can be spherical fixed reflector.During use, earlier with the theoretical elements of a fix point of cad model along the outside mobile setting height(from bottom) of this some place normal direction, the target ball is placed on the conical bore on the mount pad.Under the suction of magnet, target ball and mounting seat are close together.One hand grip mount pad, the another hand is caught the target ball, and the rotary target ball is adjusted the angle of target ball.Beginning is during navigator fix, and mobile mount pad causes the laser beam of laser tracker near the impact point.Then mount pad is attached on the curved surface, slowly adjusts the position has been positioned at impact point up to laser tracker prompting target ball position.At this moment stop to adjust mount pad, pin mount pad on the other hand, the another hand is depressed the depression bar of bolt on the backstay rapidly, stays the mark of anchor point on curved surface.Unclamp depression bar then, backstay resets under acting force of the spring.
Backstay 7 integral body can be T-shaped among the figure.

Claims (2)
