Description

Height gage

Technical field

The utility model relates to a kind of measuring instrument, and more particularly, it relates to a kind of height gage.

Background technology

What as everyone knows, spark machined adopted is all that the corresponding position of electrode pair processes. If because scale error appears in the processing to electrode, electrode large error is used on electro-spark cutting machine, the error of the product that electro-spark cutting machine cuts out so also can be very large. Therefore,, before electrode dispatches from the factory, need to check its dimensional accuracy. Height gage is a kind of common instrument of inspecting electrode dimensional accuracy. Height gage mainly by base, pillar, be located at slide unit on pillar, drive control piece, display list, the measuring staff that slide unit slides along pillar and the probe that is fixed on measuring staff end to form. The position of adjusting slide unit by control piece makes the Surface Contact of probe and electrode, and display list just can show the surperficial height at place of popping one's head in, thereby learns the actual size of electrode. In the time of the size of measurement electrode, need the different parts on measurement electrode surface, therefore, in the process of measuring, need repeatedly the position of traveling electrode, and traveling electrode completes by craft conventionally, because manual error is larger, while wanting certain position on measurement electrode surface, conventionally electrode cannot be moved to very accurate position, this just causes height gage cannot measure this position of electrode surface, and the data that record average after (being generally to survey multi-group data to average) can not reflect very accurately the actual size of electrode.

Utility model content

The deficiency existing for prior art, the purpose of this utility model is to provide a kind of height gage, and this kind of height gage is equipped with the reference unit for auxiliary moving measured object, can improve the accuracy of mobile measured object, ensures the accuracy of measuring.

For achieving the above object, the utility model provides following technical scheme:

A kind of height gage, comprise base, pillar, be located at the slide unit on pillar, control piece, display list, the measuring staff that driving slide unit slides along pillar and the probe being threaded with measuring staff, one end that probe is connected with measuring staff is spiral shell head, and one end that measuring staff is connected with probe is provided with the screw coordinating with spiral shell head, in the end that described measuring staff is connected with probe, be provided with cavity, described cavity communicates with described screw, in described cavity, be provided with visible ray light emitting source, in described probe, be provided with along its length the light sending for light emitting source through the through hole of popping one's head in.

By such scheme, thereby the visible ray that light emitting source sends can penetrate the surface that is radiated at measured object from the through hole of probe, for mobile measured object provides reference, to improve the precision of mobile measured object.

The utility model is further set to: described light emitting source is LED lamp.

Than using incandescent lamp, the power consumption of LED lamp is less.

The utility model is further set to: the wavelength of the light that described LED lamp sends is 550nm.

Because human eye is the most responsive in the yellow green of 550nm left and right to wavelength, green-yellow light can improve operator's notice concentration degree.

The utility model is further set to: the lamp socket of described LED lamp and cavity are pegged graft, and the sidewall of described cavity is provided with the opening for lamp socket turnover.

By appeal scheme, in the time that the damage of LED lamp needs to change, it can be extracted from opening, and needn't first take off probe, handled easily.

The utility model is further set to: the brightness of described LED lamp is adjustable.

By such scheme, operator can regulate according to the brightness of environment the brightness of LED lamp, for surveying work offers convenience.

Compared with prior art, the utility model has the advantages that: the utility model irradiates measured object surface by light, for mobile measured object provides reference, make the precision of mobile measured object higher, thereby improve the accuracy of measuring.

Detailed description of the invention

With reference to Fig. 1, a kind of height gage, comprise base 1, pillar 2, be located at the slide unit 3 on pillar 2, the control piece 4 that drives slide unit 3 to slide along pillar 2, display list 5, measuring staff 6, and the probe 7 being threaded with measuring staff 6, probe 7 one end that are connected with measuring staff 6 are spiral shell head, and measuring staff 6 is provided with probe 7 one end that are connected the screw coordinating with spiral shell head, measuring staff 6 is provided with cavity 9 with in probe 7 ends that are connected, cavity 9 communicates with screw, in cavity 9, be provided with visible ray light emitting source, probe 7 central part is provided with the light that sends for the light emitting source through hole 8 through probe 7 along its length. thereby the visible ray that light emitting source sends can penetrate the surface that is radiated at measured object from 7 the through hole 8 of popping one's head in, for mobile measured object provides reference, to improve the precision of mobile measured object.

The light emitting source that the utility model uses is LED lamp 12. Than using incandescent lamp, the power consumption of LED lamp 12 is less.

The wavelength of the light that LED lamp 12 sends is in addition 550nm. Because human eye is the most responsive in the yellow green of 550nm left and right to wavelength, green-yellow light can improve operator's notice concentration degree.
