Abstract

The utility model relates to a pendant meter for detecting mechanical product parts and checking instruments. The utility model, which is composed of a pendant meter rack, an adjustable standard angle square, a flat plate and two dial indicators, changes angle square qualitative detection to quantitative detection. When used, the utility model can be used conveniently like an angle square. The utility model, which has low manufacturing precision, high measuring precision, conformity to the national standard, simple structure, low cost and portability, is suitable for wide factories and enterprises.

Description

Pendant meter

Affiliated technical field:

The utility model relates to a kind of in machine-building, is used for common workshop, and in constant temperature enclosure product component and inspection utensil is carried out squareness measurement, and the observational measurement that especially can change try square is present quantitative measurment.

Background technology:

At present, known squareness measurement situation is that the product component in common machine-building workshop is to detect with try square, is to carry out at the indoor high-precision verticality detector of constant temperature to the detection of checking utensil.The detection of carrying out the product component verticality with try square is observational measurement, can not get accurate measurement data, product component delivered in the constant temperature enclosure detect, program is complicated inconvenient on the one hand, the sensing range of checkout equipment is limited on the other hand, and the size of product component, each different rare realization of shape detect.

Summary of the invention:

For the verticality that solves the engineering goods parts can not detect accurate value with try square, the detection that the utility model provides a kind of Pendant meter that product component is carried out verticality can be tried to achieve accurate error amount.The technical scheme that its technical matters that solves the utility model adopts is:

Realize that with hanging two dial gauges survey the method for hanging down at 2, as follows to the measure that verticality is measured: on a flat board be equipped with two dial gauges dangle dial framework to can adjust the standard angle chi just, two vertical planes of the back of the body successively survey and touch, and adjust, make itself and plate level try to achieve a desirable vertical plane as the standard vertical face, survey with the dial framework that dangles and touch the unit under test vertical plane, the difference that standard vertical face and tested vertical plane are relatively produced promptly is a unit under test error of perpendicularity value.The technical program hangs 2 beneficial effects of surveying the method for hanging down:

Can adjust a standard vertical temporarily and compare measurement, just can not measure at normal temperatures so do not need isoperibol to give protection, and can obtain error of perpendicularity value accurately in the face of tested vertical plane.

Description of drawings:

The utility model is described in further detail with implementing real row below in conjunction with accompanying drawing:

Fig. 1 is front view and the vertical view that can adjust the standard angle chi

Fig. 2 is the dangle front view and the vertical view of dial framework

Fig. 3 is dull and stereotyped phantom view

1 plate level, 2 laminating points, 3 laminating points, 4 upper arm, 5 underarms, 6 dial gauges, 7 Xiao's axles, 8 stop means, 9 handwheels, 10 front vertical planes, 11 back side vertical planes, 12 screws, 13 tight screws among the figure.

Wherein upper arm (4), underarm (5) can be fixed arbitrarily between the upper and lower bound of dial framework height that dangles, to guarantee the demand of different locations.Fixedly the handwheel (9) of upper arm (4) underarm (5) has the biconvex formation, is characterized in the tautness jail, decomposes loading and unloading fast.Front vertical plane (10) is a parallel surface with back side vertical plane (11).

Embodiment:

In the drawings the dial framework that dangles, can adjust the standard angle chi with being placed on the dull and stereotyped plane (1), range finding requirement according to the unit under test vertical plane, determine the range finding position, with handwheel (9) upper arm (4) and underarm (5) are fixed on the dial framework that dangles, with tight screw (13) dial gauge (6) is joined same stop means (8) fixedly on the upper arm (4), dial gauge (6) is fixed on the underarm (5) with tight screw (13).Move the dial framework survey of dangling and touch laminating points (2) and (3) applying that to adjust standard angle chi front vertical plane (10) and top dial gauge stop means (8), on adjusting then, following two dial gauge readings are zero, the dial framework that will dangle moves to can be adjusted standard angle chi back side vertical plane (11) and survey and touch, fit in same laminating points (2) and (3) with top dial gauge stop means (8), the reading of seeing following dial gauge then be on the occasion of or negative value determine to adjust direction, adjust with screw 12, front vertical plane (10) and back side vertical plane (11) can be rotated along Xiao's axle (7) sense of rotation, just change, carry on the back the angle of two vertical planes, try to achieve its desirable vertical plane.This adjustment process until adjust to dangle dial framework just, the side of the back of the body two vertical planes touches that to try to achieve upper and lower two dial gauge readings all identical, can finish to adjust.The vertical plane that adjust the standard angle square this moment just can be used as the standard vertical face.The dial framework that will dangle again moves on to the survey of unit under test vertical plane and touches, and is fitted in laminating points (2) and (3), sees the positive and negative difference of following dial gauge and top dial gauge, promptly is the positive and negative error amount of unit under test verticality.

Unit under test can be placed on this flat board and go up detection, also can move on on the other massive plate and detect.

Claims

1, a kind of Pendant meter dangle dial framework, can adjust the standard angle chi, dull and stereotyped institute constitutes, with hanging the vertical methods of 2 surveys of two dial gauges realizations tested vertical plane is carried out quantitative measurment.It is characterized in that: on a flat board be equipped with two dial gauges dangle dial framework to can adjust the standard angle chi just, two vertical planes of the back of the body successively survey and touch, and adjust, make itself and plate level try to achieve a desirable vertical plane as the standard vertical face, survey with the dial framework that dangles and touch the unit under test vertical plane, the difference that standard vertical face and tested vertical plane are relatively produced promptly is the error amount of unit under test vertical plane.

2, it is characterized in that according to the described Pendant meter of claim 1: the stop means (8) of dial framework upper arm (4) of dangling has laminating points (2) and (3) to constitute.

3, Pendant meter according to claim 1 is characterized in that: fixedly the handwheel (9) of upper arm (4) underarm (5) has biconvex to constitute.
