Description
Technical field
This utility model relates to a kind of measurement apparatus, specifically measures the device of ball centre.
Background technology
Solder sphere is a kind of parts common in structural steelwork, and its outward appearance is a spheroid, and the surface characteristic that spheroid is smooth causes when needs in-site installation measurement and positioning, and conventional location mode can not accurately find out sphere centre point.And the center that in work progress, substantial amounts of measurement job demand tack welding is received, the mode of centering finding a kind of simplicity contributes to providing efficiency of construction.
Job site was when tack welding was received in the past, can determine that welding sphere centre, or the mode of employing eye-observation, efficiency low impact construction, and precision cannot ensure by the instrument such as horizon rule, angle square.
Summary of the invention
This utility model is intended to overcome the defect of prior art, it is provided that a kind of device measuring ball centre, the problem that solution job site Sphere orientation is difficult, precision cannot ensure.
In order to solve above-mentioned technical problem, this utility model is achieved in that
A kind of device measuring ball centre, it is characterized in that: it includes the open circles band of column and spirit level, the top of the described open circles band of column is provided with shrouding, has an open circles in the center of the open circles band of column, and one end of open circles band of column upper sealing plate is located at by described spirit level.
The device of described measurement ball centre, it is characterised in that: a diameter of 300mm of the described open circles band of column, high 50mm, open circles diameter 10mm, spirit level diameter 60mm.
The beneficial effects of the utility model are: applied widely, and the product of standard Design and Machining can be used for determining the center of the spheres such as all kinds of hollow ball, medicine ball, hemisphere, have substantially met the demand of general structural steelwork construction.Mode of operation is easy, and single workman just can complete by fast operating, synchronizes to carry out prism observation；Device is small and exquisite, easy to carry.
Accompanying drawing explanation
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation that Fig. 1 overlooks direction.
Fig. 3 is to be placed on structural representation when using on spheroid.
Detailed description of the invention
As Figure 1-3: a kind of device measuring ball centre, it includes the open circles band of column 1 and spirit level 2, the top of the described open circles band of column is provided with shrouding 3, has an open circles 4 in the center of the open circles band of column, and one end of open circles band of column upper sealing plate is located at by described spirit level；
The present embodiment, with an a diameter of 300mm, high 50mm has the open circles band of column of shrouding as critical piece, and in one end of cylinder shrouding equipped with the spirit level of a diameter of 60mm, cylinder ring center sets the open circles of an a diameter of 10mm.
This device easily operates, only need field worker that it is put into solder sphere 5 upper surface, move left and right until bubble is placed in the middle after fitting with sphere, open circles band of column center is solder sphere ball centre, during measurement and positioning by reflection edge mirror holder in the central hollow circle of the open circles band of column, solder sphere center can be accurately positioned.After installation puts in place, centring means can quickly be removed, and spheroid itself is not resulted in damage.
Claims (2)
1. the device measuring ball centre, it is characterized in that: it includes the open circles band of column and spirit level, the top of the described open circles band of column is provided with shrouding, has an open circles in the center of the open circles band of column, and one end of open circles band of column upper sealing plate is located at by described spirit level.
The device of measurement ball centre the most according to claim 1, it is characterised in that: a diameter of 300mm of the described open circles band of column, high 50mm, open circles diameter 10mm, spirit level diameter 60mm.
