Abstract

The utility model relates to a tool for measuring verticality, which comprises a base seat, an upright post, a regulating sliding sleeve, meter rods and double indicators which can be dial indicators, dial test indicators or electrical measurement heads, etc. The upright post is vertically and mutually connected with the base seat, and is capable of rotating relative to the base seat along the shaft line of the upright post. The double indicators are respectively tightly locked with the upright post through a meter and a regulating sliding ring. When measuring the verticality of a part, the double indicators and the upright post together carry out coaxial and equal-radius rotation. For facilitating to read numbers, a three-dimensional included angle is arranged between two meter rods. The measuring tool has wide application scope and high measuring precision. The utility model can measure the error numerical value of verticality and can also replace universal dial indicator frames.

Description

Arrangement for measuring verticality

The utility model relates to a kind of verticality cubing, and it comprises base, column, adjusting sliding sleeve, table bar and two indicator, belongs to field of measuring techniques.

The machinery industry is to the detection of " verticality " this mass property parameter, and the normal cubing of using is try square and clearance gauge or with try square and see that by rule of thumb light slit estimates.Use the direction that above-mentioned cubing can only bigness scale verticality error, and can not survey the numerical value of the error of perpendicularity.In addition, because the try square specification is few, sensing range is restricted, and is yielding through the try square that uses and deposit, and repairs difficulty.Because of using this kind cubing, error is big, so it only is applicable to that the rough verticality of general part detects.

The purpose of this utility model is to overcome above-mentioned weak point of the prior art and a kind of high verticality cubing that can record error of perpendicularity numerical value of the little measuring accuracy of self error that can be applicable to shown in GB1958-80 shape and the position of related features standard the various squareness measurements of example is provided.

The purpose of this utility model is realized by following measure: a kind of verticality cubing, and it comprises base, column, adjusting sliding sleeve, two indicator and table bar, its main points are that column links to each other with base is vertical, and can rotate relative to base along its axis.Two indicators are locked on the column by table bar, adjusting sliding sleeve respectively.

The utility model is described in further detail below in conjunction with the embodiment accompanying drawing.

Fig. 1 is this cubing structural representation.

Fig. 2 is the vertical view of Fig. 1.

Fig. 3 is to use a kind of correction synoptic diagram before this cubing.

Fig. 4 is to use this cubing to carry out the example schematic that severe detects.

Fig. 5 is a kind of axonometric drawing of regulating sliding sleeve.

Referring to Fig. 1, Fig. 2, column 9 is vertically mounted in the lining 2 that is fixed as one with base 1, and can rotate relative to base 1, lining 2 along its axis.Lining 2 is for wear-resistant and ad hoc.Rotate flexibly for making, can add lubricant at the surface of contact place of column 9 and lining 2.Indicator can select for use clock gauge, dial gauge and electrical measurement first-class, and present embodiment only is example with the clock gauge, and

clock gauge

11,13 is regulated sliding sleeve 5,7 usefulness jackscrews 3,8 by table bar 4,6 respectively and is fastened on the column 9.Table bar the 4, the 6th is fastened on respectively by locking knob 16,17 and analog thereof and adjusts on the sliding sleeve 5,7, and clock gauge the 11, the 13rd is fastened on table bar 4,6 ends by locking knob 18,19 and analog thereof respectively.Like this, using this cubing that tested part is in addition carried out the error of perpendicularity when detecting, armrest is moving, and two

clock gauges

11,13 just can rotate with radiuses such as column 9 are coaxial.When with the flatness of this cubing detection plane, one of them gauge outfit of turn, make its along the hinged place 10 or 15 and analog rotate, make its

gauge head

12 or 14 straight down.In addition,, can unscrew jackscrew 3,8, adjust the relative position of 11,13 in two clock gauges by means of the slip of adjusting sliding sleeve 5,7 relative columns 9 according to detecting needs.Referring to Fig. 3, reading when detecting staggers the working time of two

clock gauges

11,13, thus make 4,6 on two table bars that a three-dimensional angle be arranged, but preferably make angle between two bars between 10-30 °.

Referring to Fig. 3, before using this cubing, can carry out 0 bit correction by means of column angle gauge 20 and two

clock gauges

11,13 of measuring dull and stereotyped 21 pairs of these cubings, to be corrected good after, promptly available this cubing is carried out the error of perpendicularity to tested part in addition and is detected.

Referring to Fig. 4, establishing tested part 23 in addition is benchmark with bottom surface 22, with proofreading and correct the error of perpendicularity of good this cubing detection axis to reference field 22.At first tested in addition part 23 and this cubing are placed on same the detections flat board 21, cubing is shifted to the periphery of tested axis, the

gauge head

12,14 of two

clock gauges

11,13 is contacted with the measured circle cylinder respectively, and certain meter-pressing amount is arranged.Go up at orthogonal both direction (x, y) respectively then and rotate cubing column 9, and the reading of record clock gauge, then the error of perpendicularity of both direction is respectively:

Fx=| table 11x-table Bx|, the fy=| table 11y-table By| then error of perpendicularity of this other part is: f=

\sqrt{{(fx)}^{2} + {(fy)}^{2}}

Referring to Fig. 5, cause damage in order to prevent jackscrew and locking knob column and table bar surface, regulate sliding sleeve 24 and preferably make spring clip type, and fastening with screw fastening mode and column with the table bar.Indicator is also preferably selected this connecting mode for use with table being connected of bar.

Verticality cubing provided by the utility model is widely applicable, the little measuring accuracy height of self error, and can record error of perpendicularity numerical value.This cubing is simple in structure, and cost of manufacture is low, and is easy to operate, and can replace omnipotent dial holder to use.
