Abstract
The invention discloses an outwards-convex type step gauge without a cushion block. The outwards-convex type step gauge without the cushion block comprises a base and a plurality of measuring columns. The cross section of the base is in an I shape or an n shape or a pi shape. The upper surface of the base is provided with a groove. The groove is divided into a plurality of sections through cutting according to the size of a step. The measuring columns are fixed into the sections of the groove in sequence. Each measuring column is columnar. The cross section of each measuring column is round or rectangular or in other shapes. The two ends of each measuring column can also be in a frustum shape. The two end faces of each measuring column are two parallel flat measuring faces. The step gauge with the measuring columns embedded into the convex type grooves is called the outwards-convex type step gauge without the cushion block for short. According to the outwards-convex type step gauge without the cushion block, the structure is simple, the manufacturability is good, use is quite convenient and rapid, measuring heads of a measuring gauge can conveniently enter from the upper surface, the left surface and the right surface to be in contact with the measuring faces of the measuring columns, measurement is safe and reliable, and the working efficiency is high.
Description
Technical field
The invention belongs to the step gage in measurement instrument field, particularly relate to a kind of raised type without cushion block step gage.
Background technology
Step gage is accurate length material standard device, and for examining and determine accurate three coordinate measuring machine and numerical control machining center, its precision is high, and manufacture difficulty is very large, expensive.Traditional step gage has two kinds of structures: one is the step gage having standard size cushion block, and another kind is the step gage without standard size cushion block.The stability of size is the important technology index of step gage, and the step gage dimensional stability without standard size cushion block is better than there being the step gage of standard size cushion block.At present, measurement column without cushion block step gage is concave, its groove is at the middle part of microscler pedestal xsect, measurement column is fixed in the groove in the middle part of pedestal xsect, the both sides of pedestal and bottom surface are provided with several isometrical through holes, during measurement, the measuring head of scale need could enter from left surface and right flank through each through hole and contact with the measuring surface of measurement column; Simultaneously, existing without cushion block step gage complex structure, operation uses very inconvenient, the measuring head of slightly careless scale also can collide with the surface of through hole, the safe reliability measured is poor, inefficiency, and manufacture difficulty is very large, domesticly there is no accurate concave without cushion block step gage production marketing, large price need be spent from external import.
Summary of the invention
For current measurement column be concave without cushion block step gage Problems existing, the present invention proposes a kind of measurement column is the technical scheme of raised type without cushion block step gage.It comprises microscler pedestal and several survey mass, the xsect of pedestal is in ' work ' font, ' п ' font or ' π ' font, its upper surface has raised type groove in the axial direction, groove is divided into some sections by step pitch size is cut, and several measurement columns are fixed in the groove of some sections successively.
The shape of described measurement column is cylindricality, and its xsect can be circle, rectangle or other shape.Cylindricality measurement column can be common cylindricality, or cylindricality two ends is taper type, and the both ends of the surface of measurement column are two parallel flat measuring surface.
The invention has the beneficial effects as follows:
Its structural reduction, good stability of the dimension, better without cushion block step gage anufacturability than concave, manufacturing cost reduces, use extremely convenient and swift, the measuring head of scale can easily from above, the left side enters with direction, three, the right side and contacts with the measuring surface of measurement column, measure safe and reliable, work efficiency is high.

In figure: 1 microscler pedestal, 2 measurement columns.
Embodiment
As shown in Figures 1 to 6, raised type of the present invention comprises microscler pedestal 1 and measurement column 2 without cushion block step gage, the upper surface of microscler pedestal is raised type groove in the axial direction, and groove is divided into some sections by step pitch size is cut, and several measurement columns are fixed in the groove of some sections successively.Wherein, for alleviating step gage weight and increasing Strong rigidity, the xsect of microscler pedestal is designed to ' work ' font (Fig. 1,2), ' п ' font (Fig. 3,4) or ' π ' font (Fig. 5,6).Measurement column is common cylindricality (Fig. 7,8,11) or cylindricality two ends is taper type (Fig. 9,10), its circular in cross-section, rectangle or other shape, cylindricality both ends of the surface are two parallel flat measuring surface, and the distance of two adjacent measurement columns measuring surface is in the same way a step pitch size.
Claims (4)
1. a raised type is without cushion block step gage, comprise microscler pedestal and measurement column, it is characterized in that: the upper surface of described microscler pedestal has raised type groove in the axial direction, groove is divided into some sections by step pitch size is cut, and several measurement columns are fixed in the groove of some sections successively.
2. according to the raised type shown in claim 1 without cushion block step gage, it is characterized in that: the xsect below described microscler pedestal raised type groove is in ' work ' font, ' п ' font or ' π ' font.
3. according to the raised type shown in claim 2 without cushion block step gage, it is characterized in that: described measurement column is cylindricality, its circular in cross-section, rectangle or other shape, cylindricality both ends of the surface are two parallel flat measuring surface.
