Description
Technical field
The utility model belongs to the technical field of measurement profile or curvature.
Background technology
Currently, on some high-accuracy mechanical parts the measurement of arc surface circularity mainly by roundness measuring instrument, existing circularity is surveyed
Amount instrument needs to be placed on part to be measured in the Measuring plate of measuring instrument and measures.However, corresponding measuring instrument complex operation, instrument valency
Lattice are high, and measurement cost is high.
For example, " large-scale three coordinate measuring machine " can measure the circularity of part, but by its measurement head joint arm gap and weight
The influence of multiple positioning precision.And, the use environment and instrument self space of three coordinate measuring machine are often subject to limitation, cause to survey
The precision of amount is not high enough.Dial gauge traditional measurement method owned by France, measuring instrument precision and digitized degree Shortcomings that it is used；
CCD measures noncontact measuring method owned by France, does not have the above-mentioned deficiency of three coordinate measuring machine and dial gauge method, but CCD mensurations are made
Instrumentation is complicated, instrument price is high, and measurement cost is high.
Therefore, for some medium-sized and small enterprises, it is badly in need of a kind of simple to operate, the low interchangeable circularity inspection of measurement cost
Survey device.In order to solve the above problems, our company have developed a kind of circularity detection device, and simple structure, measurement is convenient.But,
During actual use, because the size of workpiece for measurement is more various, and each workpiece for measurement needs corresponding circularity
Detection means, causes relatively costly.Therefore, also further room for improvement.
Utility model content
The purpose of this utility model is the roundness measurement dress for providing a kind of workpiece for measurement of measurable various different models
Put.
In order to achieve the above object, base case of the present utility model provides a kind of interchangeable circularity detection device, including

One adjustment unit and the first half slot, the second adjustment unit and the second half slot flush, are increasing or are reducing arc bearing shell
When operate more facilitate；On the other hand, the first adjustment unit is equipped with the second adjustment unit, may be such that whole equipment
Coordinate even closer, measurement result is more accurate.
Scheme three：Scheme is preferred based on this, and the cover plate is provided with jacking block, the jacking block and cavity can gap match somebody with somebody
Close.When cover plate and base engagement, jacking block then forms gap and coordinates with cavity, it can be ensured that jacking block promotes balance weight to move down.
Scheme four：Scheme is preferred based on this, and the indicator lamp is LED lamp.Led lamps are easy to observation, convenient directly perceived.
Scheme five：Scheme is preferred based on this, and the elastic component is stainless steel stage clip.The coefficient of elasticity of stainless steel stage clip
Height, and be difficult to get rusty, long service life.
Brief description of the drawings
Fig. 1 is the structural representation of the interchangeable circularity detection device of the utility model embodiment.
Fig. 2 is the phantom of day chessboard component in Fig. 1.
Specific embodiment
The utility model is described in further detail below by specific embodiment：
Reference in Figure of description includes：Base 10, pressing plate 20, elevating mechanism 30, jacking block 40, bearing 51, branch

As shown in figure 1, interchangeable circularity detection device, from top to bottom respectively elevating mechanism 30, cover plate, jacking block 40, inspection
Survey unit and base 10.Elevating mechanism 30 uses hydraulic elevator.Hydraulic elevator in the market can easily buy, low cost,
And lifting is convenient.Cover plate is provided with the first groove, overall curved, and is respectively arranged at two ends with jacking block 40 in the left and right of cover plate.
The size on the top for being dimensioned slightly smaller than cavity of jacking block 40 so that when cover plate is covered, jacking block 40 forms gap and coordinates with cavity, can
Ensure that jacking block 40 promotes balance weight to move down.
Base 10 is provided with cavity and the second groove with the first matching grooves, and its size is more than common workpiece.First
First adjustment unit is installed in groove, the second adjustment unit is installed in the second groove.First adjustment unit and the second regulation
Unit includes some arc bearing shells 70 being mutually matched, and adjacent arc bearing shell 70 is respectively ferrimagnet and magnet.Magnetic
Iron uses permanent magnet, is preferably coated with one layer of wear-resistant layer on its surface, and ferrimagnet is made of common iron, best
One layer of antirust coat is coated with its surface, to increase service life.It can be seen that arc bearing shell 70 in the first adjustment unit compared with
It is short, draw-in groove 80 is formed, the arc bearing shell 70 in the second adjustment unit is more long, just coordinates with draw-in groove.Arc bearing shell 70 is set
It is iron and the mode of magnet, it is easy to adjust.
Detection unit is provided with cavity.Detection unit includes day chessboard component, the first trigger switch, the second trigger switch
And indicator lamp.Indicator lamp is conveniently watched using led etc., and on base 10.Its chessboard component includes pole 52, balancing pole
53rd, bearing 51 and elastic component.
Bearing 51 is welded on the middle part of cavity, and pole 52 is welded on the middle part of base 10.As shown in Fig. 2 balancing pole 53 is in U
Shape, and the middle part of balancing pole 53 is provided with the spherical groove of pole 52.The upper end of pole 52 is in spherical more than the diameter of pole 52, and is inserted
Enter in the groove of pole 52, the size of the groove of pole 52 is more than the size of the upper end of pole 52.Elastic component is made by stainless steel suppresses spring,
And elastic component is set on pole 52.
First trigger switch, the second trigger switch are respectively positioned on the lower section of balancing pole 53, and the first trigger switch, the second triggering are opened
Pass is symmetrical arranged along pole 52, and the first trigger switch and the second trigger switch are connected with indicator lamp.First half slot and second
When half slot constitutes a circular groove, the first trigger switch and the second trigger switch are closed.
During concrete operations, workpiece for measurement is taken out, then corresponding increase or the first adjustment unit of reduction and the second regulation
The quantity of the arc bearing shell 70 in unit so that the normal circularity of workpiece for measurement is just equal to the first adjustment unit with the second regulation
The circularity of the circular groove of unit composition.If the size of workpiece for measurement is larger, the quantity of arc bearing shell 70 is reduced；If work to be measured
The size of part is smaller, then increase the quantity of arc bearing shell 70.Workpiece for measurement is put into the first circular groove.Start elevating mechanism
30, move down pressing plate 20.If the circularity of workpiece for measurement meets the requirements, after cover plate and base 10 coordinate, the first circular groove with
The circular groove of the second circular groove composition is just matched with workpiece for measurement, and now, the first trigger switch and the second trigger switch are closed, and are indicated
Lamp is lighted.If the circularity of workpiece for measurement is undesirable, cover plate cannot completely be covered with base 10, and now, only first touches
Hair switch or the second trigger switch closure, indicator lamp do not work.
Compared with traditional interchangeable circularity detection device, this programme only needs control cover plate to move down, simple to operate.Together
When, whole equipment simple structure, low cost carries out judging whether the circularity of workpiece meets the requirements by indicator lamp, simple straight
See.
