Abstract

The utility model discloses a diameter measuring device for a large-diameter object. The utility model is composed of a sliding negative scaleplate, a horizontal scaleplate and a bracket. The sliding negative scaleplate is perpendicular to the horizontal scaleplate, a scale is decided according to the range of measurement, and the scale can be dozens of millimeters to a plurality of meters. The utility model which has the advantages of simple structure, convenient use, wide rang of measurement and high measuring accuracy is suitable for measuring the diameter of the large-diameter object and is especially favorable for measurring the diameter of a roller in surfacing.

Description

A kind of diameter measurer of major diameter object

The utility model belongs to measuring appliance, particularly the diameter measurer of major diameter object.

In smelter, the major diameter kind of object is more, and wherein roll is exactly one of common major diameter object.As everyone knows, roll will wear and tear in the course of the work gradually, and may wear to a certain degree then needs to repair.Conventional restorative procedure is cutting again after the built-up welding, and the roller diameter measurement in the built-up welding is the comparison difficulty.

Generally speaking, roll needs limit heating edge welding in weld deposit process.In order to prevent heat dissipation, sealed with stay-warm case usually.In the prior art, the diameter of premeasuring surfacing roll must hang away stay-warm case with crane earlier, uses kind of calliper again, and there are following deficiency in the method for this measurement roller diameter and device:

1. lose time, every measurement once need be with about 30 minutes;

2. waste material resources must have the crane coordinating operation;

3. waste man-hour, for reduce measuring number of times, which floor would rather weld sometimes more, not only having taken material but also when taking a lot of work;

4. inefficiency because measure dot number is limited, can not definitely be measured certain any diameter, test leakage sometimes short chi point, in turning processing, just be found, then need return built-up welding again, seriously influenced work efficiency.

The purpose of this utility model is to provide a kind of simple in structure at the deficiencies in the prior art, and is easy to use, and the major diameter object diameter measurer that measurement range is wide and precision is high is specially adapted to the measurement of any spot diameter of roll in the built-up welding.

The utility model is by the negative scale that moves about, horizontal ruler and be configured to.Groove is carved with in the support upper end, and horizontal ruler places in the groove.Move about negative scale perpendicular to horizontal ruler, connect by the vernier slip cap between two chis, with guarantee that two chis are vertical and move about negative scale horizontal ruler up and down and about move freely.The what is called negative scale that moves about, promptly the chi forward end apex is the maximal value of measurement range, just the distance from the axis of support hold-down nut to the horizontal ruler lower edge.Concrete scale setting can be decided according to measurement range.

During measurement, with set bolt support is fixed on the testee axis, its reading that moves about negative scale and horizontal ruler intersection point is the radius of testee.

The utility model has overcome the deficiencies in the prior art, has the following advantages:

1. simple in structure, cheap.Constitute the parts processing and manufacturing on the spot voluntarily of this device.

2. easy to use, the operator is as with the direct measurement of slide calliper rule.

3. measurement range is wide, can measure the testee diameter of any arbitrarily, and scope all can by tens millimeters to several meters.

4. measure smart height, can reach 0.5 ‰.

5. save man-hour, increase work efficiency.In order to measure roller diameter in the built-up welding, need not hang away stay-warm case, can directly measure.

Embodiment below in conjunction with in the accompanying drawing is described in detail the utility model.

Fig. 1 is the structural representation of major diameter object diameter measurer.

Fig. 2 is the side view of Fig. 1.

Fig. 3 is the partial enlarged drawing of A among Fig. 1.

Fig. 4 is the side view of Fig. 3.

1 is the negative scale that moves about among the figure, and 2 is horizontal ruler, and 3 is support, and 4 is set bolt, and 5 is the vernier slip cap.The negative scale 1 that moves about selects for use the stainless steel high-abrasive material to make with horizontal ruler 2.Negative scale 1 front end that moves about is sharp type, and its scale is decided to be 1000mm.Promptly carving successively from negative scale 1 front end that moves about is 1000mm, 999mm998mm ..., 0mm.Move about and be connected by vernier slip cap 5 between negative scale 1 and the horizontal ruler 2.Vernier slip cap 5 can be made by " ten " font sheet iron.The upper and lower chimb of " ten " font sheet iron is distinguished lateral bending 180 degree inwards, be stuck on the horizontal ruler 2; With outside lateral bending 180 degree of left and right sides chimb, the negative scale 1 that moves about is limited to the inside again, the feasible negative scale 1 that moves about moves freely at the upper and lower of horizontal ruler 2.At two grooves of the upper end of support 3 design, be convenient to the installation of horizontal ruler 2 or move.

During measurement, earlier support 3 is fixed on abreast on the axis of measured object with set bolt 4, the horizontal ruler 2 that connects and the negative scale 1 that moves about are placed in the groove of support 3, its reading that moves about negative scale 1 and horizontal ruler 2 intersection points is the radius of testee again.

Claims

1, a kind of diameter measurer of major diameter object is characterized in that it is made up of the negative scale (1) that moves about, horizontal ruler (2), support (3), set bolt (4), vernier slip cap (5); Groove is carved with in support (3) upper end, and horizontal ruler (2) places in this groove, and the negative scale (1) that moves about connects with vernier slip cap (5) between two chis perpendicular to horizontal ruler (2), and two scales can be free to slide.

2, according to the diameter measurer of the major diameter object of claim 1, it is characterized in that described negative scale (1) front end that moves about is sharp type, its meter full scale is 1000mm, and carving successively from the negative scale front end that moves about is 1000mm, 999mm, and 998mm ..., 0mm.

3, according to the diameter measurer of the major diameter object of claim 1, it is characterized in that described vernier slip cap (5) made by " ten " font sheet iron, the upper and lower chimb of " ten " word sheet iron is spent to inboard bending 180, be stuck on the horizontal ruler, with left and right sides flange bending laterally 180 degree, the negative scale (1) that will move about is limited to the inside again.
