The utility model is further improved to be that described slip gauge head is enclosed within on the described stock; Described slip gauge head is fastened on the described stock by locking member.
The utility model is further improved to be that described support and described location-plate are fixed by two keepers; Described keeper and described fixedly gauge head are positioned on the same circumference; Described stock is vertical with the line of described two keepers.
The utility model is further improved to be, described meter can fix or fixing sleeve on described stock; Described meter is positioned between described slip gauge head and described support.
The utility model is further improved to be that described stock is rotatable; Described meter writes down the situation of change of numerical value in the described stock rotary course.
The utility model is further improved to be that described keeper is a pulley.
The utility model is further improved to be that described stock is provided with scale value; Described slip gauge head is provided with the interval of scale value and slides on stock.
The beneficial effects of the utility model are: stock can continuously roll along the object inwall, and the caliber error is passed on the meter by push rod; Stock can find the error of pipeline circularity by the rotations of 180 degree, and this measuring instrument is measured continuously, no leak source, accurate, direct-reading; Also can measure large-scale round part deviation from circular from.
Description of drawings
Fig. 1 is the utility model pipeline roundness measurement structural representation.
Embodiment
Below in conjunction with accompanying drawing, the utility model will be further described.
As Fig. 1, a kind of pipeline roundness measuring instrument comprises location-plate 4, support 6, meter 8, gauge head and stock 1; Described gauge head comprises fixedly gauge head 3 and slip gauge head 2; Described slip gauge head 2 is connected with described stock 1; Described meter 8 is fixed on the described stock 1; Described fixedly gauge head 3 is positioned at the end of described stock 1; Described location-plate 4 and described support 6 are fixed by web member; Described location-plate 4 and described support 6 are positioned at the both sides of described stock 1; 3 of fixedly gauge heads described support 6 and described also are provided with elastic component, can be big spring 5 here; One end of described support 6 is replaced described elastic component; The other end of described support 6 is established the push rod that is with elastic component; In real process, can use little spring 7; The gauge head of described meter 8 is replaced described push rod; The string face that described stock 1 vertical described location-plate 4 constitutes.
Described slip gauge head 2 is enclosed within on the described stock 1; Described slip gauge head 2 is fastened on the described stock 1 by locking member.
Described support 6 and described location-plate 4 are fixed by two keepers; Described keeper and described fixedly gauge head 3 are positioned on the same circumference; Described stock 1 is vertical with the line of described two keepers.
Described meter 8 can fix or fixing sleeve on described stock 1; Described meter 8 is positioned at 6 on described slip gauge head 2 and described support.
Described stock 1 is rotatable; The situation of change of numerical value in described stock 1 rotary course of described meter 8 records.
Described keeper is a pulley.
1 is provided with scale value on the described stock; Described slip gauge head 2 is provided with the interval of scale value and slides on stock 1.
In the time of in the actual measurement process, because stock is vertically divided the string that location-plate constitutes equally, so must cross the center of circle of measured workpiece.Stock 1 is pressed in gauge head 3 and slip gauge head 2 on the tested pipeline by little spring 7, and in the process of stock Rotate 180 degree, the variation of distance will reflect by meter (as dial gauge) between gauge head 3 and the slip gauge head 2, thereby shows diameter variation.
This instrument can be measured inside and outside footpath error simultaneously, below comes by concrete using method that the utility model is described in further detail.
