Abstract
The invention discloses an installing fixture used for three-coordinate measurement of long cylindrical workpieces. The installing fixture comprises two sets of positioning components, and also comprises two mutually parallel positioning slideways which are fixed on the top surface of the panel of a three-coordinate measuring machine via three connecting plates. The tail ens of the positioning slideways is vertically provided with a positioning plate. Each positioning component comprises a lower positioning frame and an upper fixing frame which are connected via a positioning pin. The lower end of the lower positioning frame and the positioning slideways are fixed via a bolt. The upper fixing frame has a curved plate structure and multiple evenly distributed threaded holes are formed on the upper fixing frame, and positioning balls are installed in the threaded holes. The lower positioning frame has a convex type structure of which the upper end forms a V-shaped positioning slot and the lower end forms a rectangular slot. Effective positioning can be realized so that application of the fixture is more convenient; measurement efficiency and precision can be enhanced; and positioning is performed by using plastic ball head bead spring plungers so that scratching of measured workpieces and extruding deformation in positioning can be avoided.
Description
Technical field
The invention belongs to one to be installed tool, be specifically related to a kind of tool that is installed for three-dimensional coordinates measurement long cylinder class workpiece.
Background technology
Be limited to the restriction of three coordinate measuring machine Z axis measuring height, length exceeded to the long cylinder class measured piece of Z axis measurement range, scheme conveniently vertically can not be placed on worktable and measure, need along Y direction flat sleeping on the table, can measure.According to the measuring principle of three-dimensional, if measured piece can not wherein an axle be completely parallel with XYZ axle, then causes three-dimensional to get the shape fitted to ready and occur deviation, therefore the key factor affecting its measuring accuracy is become on the orientation problem of long cylinder class workpiece.Below the long cylinder class workpiece of Z axis measurement range is exceeded referred to as long cylinder class workpiece to length.
As shown in Figure 1, 2, locator meams of the prior art uses two pieces of V-blocks 15 to support tested cartridge type workpiece 14, in order to make the central axis of tested long cylinder workpiece 14 parallel with three-dimensional Y-axis, need before placement measured workpiece 14, the supporting surface of two pieces of V-blocks 15 is adjusted to parallel with three-dimensional Y-axis, and as much as possible in one plane.
Although this localization method solves the problem of the flat sleeping long cylinder of location survey, the time of adjustment in early stage V-block is longer, is limited to the mode adjusted manually, and the location of V-block neither entirely accurate, to measuring accuracy with measure efficiency and bring certain influence.Locating device of the prior art can not realize locating fast and accurately.
Summary of the invention
The present invention proposes to overcome the shortcoming existed in prior art, its objective is and provides a kind of tool that is installed for three-dimensional coordinates measurement long cylinder class workpiece.
Technical scheme of the present invention is:
For the tool that is installed of three-dimensional coordinates measurement long cylinder class workpiece, comprise two groups of positioning components, also comprise two locator slides be parallel to each other being fixed on end face on three coordinate measuring machine flat board by three pieces of web joints, the ending vertical of locator slide is provided with location-plate; Described positioning component comprises the lower locating rack and upper holder that are connected by register pin; Lower locating rack lower end is fixed by bolt and locator slide; Fixed frame arc plate structure, it forms multiple uniform threaded hole, is provided with positioning bead in threaded hole; Described lower locating rack is convex structure, and upper end forms V-type locating slot, and lower end forms rectangular recess.
The dull and stereotyped sidewall of three coordinate measuring machine is close to by described location-plate.
The invention has the beneficial effects as follows:
The present invention effectively can locate putting down along Y-axis the long cylinder class workpiece measured on three coordinate measuring machine that crouches, and it is more convenient that use is installed; Be conducive to the measurement efficiency and the precision that improve long cylinder class workpiece; Owing to adopting baton round bow wave pearl spring-loaded plunger to position, avoid crimp when scuffing and location that measured workpiece is produced; Adopt the supporting surface of locator slide restriction guarantee two locating racks parallel with three-dimensional Y-axis, and achieve the adjustable moving of two locating racks position in the Y-axis direction, avoid the collision of locating rack and gauge head in three-dimensional coordinates measurement, effectively raise the degree of safety of measurement.

Embodiment
Carry out a kind of tool that is installed for three-dimensional coordinates measurement long cylinder class workpiece below in conjunction with Figure of description and embodiment to the present invention to describe in detail:
As shown in Fig. 3 ~ 6, a kind of tool that is installed for three-dimensional coordinates measurement long cylinder class workpiece, comprise two groups of positioning components 1, also comprise two locator slides be parallel to each other 2 being fixed on end face on three coordinate measuring machine flat board 13 by three pieces of web joints 3, the ending vertical of locator slide 3 is provided with location-plate 4; Described positioning component 1 comprises the lower locating rack 6 and upper holder 7 that are connected by register pin 5; Lower locating rack 6 lower end is fixed by bolt 8 and locator slide 2; Fixed frame 7 arc plate structure, it forms multiple uniform threaded hole 9, is provided with positioning bead 10 in threaded hole 9; Described lower locating rack 6 is in convex structure, and upper end forms V-type locating slot 11, and lower end forms rectangular recess 12.
Dull and stereotyped 13 sidewalls of three coordinate measuring machine are close to by described location-plate 4.
Described positioning bead 10 is baton round bow wave pearl spring-loaded plunger.
Using method of the present invention:
Workpiece 14 is positioned in the V-type locating slot 11 of lower locating rack 6 upper end, puts upper holder 7, and with register pin 5, lower locating rack 6 and upper holder 7 are fixed; Lower locating rack 6 lower end adopts locator slide 2 to position, this slideway serves the effect of location, and make two positioning components 1 in the effective length of slideway, as required along three coordinate measuring machine Y direction adjustment position, adjusted position postpone uses bolt 8 to lock.
