Description

Distance measurement instrument

Technical field

The utility model relates to a kind of surveying instrument, specifically a kind ofly can be applied to the spacing of commercial unit, the measurement mechanism in gap, belongs to machinery manufacturing industry technical field.

Background technology

Generally speaking, distance measurement instrument is a kind of instrument for the special distance measurement of machinery manufacturing industry, is applied to metallurgical production industry, and casting casement is measured and needed the measurement accurately measuring distance between two articles.

In mechanical processing industry, inner bore of part and part depths clearance measurement never good measurement means.Measuring accuracy is always different along with the skill level difference of operating personnel.Especially in the place that accuracy requirement is high, the measurement means that the measurement as cast tube pipe die endoporus has never had, and also the measurement of steel-making continuous casting roller is related to the quality of slab quality and the safety of the quality of production.

The roll gap of distance measurement instrument by measuring instrument, the instrument of spacing that exist in prior art are all be arranged in gauge outfit by digital wash, and gauge outfit in use can be caused to loosen and then damage, this is the topmost reason causing digital wash to damage.

Utility model content

Have problems for above-mentioned prior art, the utility model provides a kind of distance measurement instrument, and its structure is simple, can according to actual conditions, measure the distance in endoporus and gap accurately, and can ensure that digital indicator is arranged in gauge outfit and do not loosen, reliably durable.

For achieving the above object, the technical solution adopted in the utility model is: a kind of distance measurement instrument, comprises digital wash and extension rod, also comprises table fixture, and described digital wash is arranged on described extension rod one end by table fixture; The described extension rod other end is provided with copper sliding sleeve regulating device and guiding trolley device;

Described copper sliding sleeve regulating device comprises sounding rod, copper sliding sleeve, spring, guiding gland and fixed screw; Described guiding trolley device comprises shield bearing, axle, gland and vehicle frame;

Described copper sliding sleeve regulating device is arranged on described guiding trolley device, and described copper sliding sleeve regulating device can be slided by guiding trolley device relatively.

Further, described sounding rod is arranged in copper sliding sleeve, and sounding rod can move in copper sliding sleeve.

Further, on described sounding rod, cover has spring, and described spring is sealed in described copper sliding sleeve by described guiding gland.

Further, described guiding gland is fixed together by fixed screw and described copper sliding sleeve.

Further, described vehicle frame solid bearing, and described vehicle frame is connected with described copper sliding sleeve regulating device.

Further, described vehicle frame has circular groove, and be provided with screw hole on circular groove; Described copper sliding sleeve regulating device is linked together by screw and described vehicle frame.

The beneficial effects of the utility model are:

1), show the connector that fixture is used to stationary digital indicator gauge and sounding rod, the feature that the design showing clamp device can prevent the digital wash gauge outfit of traditional roll gap measuring instrument perishable, the life-span of digital wash is at least more than original twice;

2), copper sliding sleeve regulating device is arranged on guiding trolley frame, fixed by tight fixed bolt.Copper sliding sleeve regulating device is adjustable at the upper-lower position of dolly saddle, can adapt to the change of more big roller footpath scope like this, and position is more upwards installed, and adapt to comparatively pony roll footpath, position is installed downwards, adapts to comparatively big roller footpath.Sounding rod is to move up and down in copper sliding sleeve inside, replys original position downwards under the action of the spring.

3), this apparatus structure is simple, and operating personnel are easy to use, and can accurately measure surveyed object.
