Abstract
The utility model relates to ball roundness measurement mechanism, comprising: board; Two grip devices of left and right vertical setting, its on the same line and at least one grip device along this rectilinear direction slide arrange; Upper and lower horizontally disposed two pallets, two pallets to be arranged on board and between described two grip devices, and top tray is slided along the vertical direction of board and arranged; Whirligig, to be arranged on arbitrary grip device and at the rotation with in surface of vertical direction; And circularity detection device, be arranged on grip device and/or pallet, detect the displacement of grip device, pallet.The utility model is ball to be positioned between two grip devices and slide one or two grip devices make the outside surface of two grip devices and ball tangent, mobile top tray makes the outside surface of itself and ball tangent, grip device and top tray is again adjusted after the angle of whirligig screw setting, circularity detection device detects the displacement of grip device and top tray, thus measures the circularity of ball.
Description
Technical field
The utility model belongs to ball proving installation, particularly relates to a kind of ball roundness measurement mechanism.
Background technology
Ball is a kind of sports goods, there is oval ball, as rugby etc., circular ball, as basketball, vollyball, football etc., no matter be which kind of ball, its set shape is very important, the oval ellipse with regard to being standard, the circular circle with regard to being standard, otherwise will have influence on the result of use of ball, be ball production testing link of dispatching from the factory in the link controlling ball standard shape, this link is most important.
In prior art, the detection of ball roundness is that checker adopts naked eyes or feel to weigh mostly, be easy to deviation occurs, some is close to 99% and utilizes eyesight experience to judge close to the circularity of the ball of proper circle cannot detect by checker, it is that ball defective is just easy to come into the market in fact that such surface looks like very round, brings loss to consumer.
Utility model content
The purpose of this utility model is the defect overcoming prior art existence, provides a kind of ball roundness measurement mechanism.
The technical scheme realizing the utility model object is: ball roundness measurement mechanism, comprising:
Board;
Left and right two grip devices be vertically arranged on described board, described two grip devices on the same line and at least one grip device along this rectilinear direction slide arrange;
Upper and lower horizontally disposed two pallets, described two pallets to be arranged on described board and between described two grip devices, and top tray is slided along the vertical direction of board and arranged;
Whirligig, described whirligig to be arranged on arbitrary grip device and the rotation with in surface of vertical direction at board;
And circularity detection device, be arranged on described grip device and/or described pallet, detect the displacement of described grip device, described pallet.
Further, be provided with line slideway and fixture drive unit, described line slideway is horizontally placed on described board, and described two grip devices are arranged on described line slideway, and described fixture drive unit is connected with at least one grip device.
Further, described whirligig comprises catching.
Further, described catching is inner concavity structure.
Further, the surface contacted with ball of described catching is also provided with sawtooth.
Further, described catching is elastic component.
Further, the propulsion system driving described whirligig to rotate also are provided with.
The utility model has positive effect: to be ballly positioned between two grip devices and slide one or two grip devices make the outside surface of two grip devices and ball tangent, mobile top tray makes the outside surface of itself and ball tangent, grip device and top tray is again adjusted after the angle of whirligig screw setting, circularity detection device detects the displacement of grip device and top tray, thus measures the circularity of ball.
Accompanying drawing explanation
In order to make content of the present utility model more easily be clearly understood, below according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail, wherein:
Fig. 1 is structural representation of the present utility model.
Wherein: 1, fixture drive unit, 2, propulsion system, 3, grip device, 4, whirligig, 5, pallet, 6, board.
Embodiment
As Fig. 1, ball roundness measurement mechanism, some of them embodiment, comprising:
Board 6;
Left and right be vertically arranged at two grip devices, 3, two grip devices 3 on board 6 on the same line and two grip devices 3 slide along this rectilinear direction and arrange;

Whirligig 4, whirligig 4 to be arranged on the grip device of left side and the rotation with in surface of vertical direction at board 6;
And circularity detection device (not indicating in figure), be arranged in grip device 3 and top tray, detect the displacement of grip device 3, top tray.
According to actual needs, can select, circularity detection device is linear displacement transducer, photoelectric sensor etc., is specifically not construed as limiting.
Beneficial effect of the present invention: to be ballly positioned between two grip devices 3 and two grip devices 3 that slide make two grip devices 3 tangent with the outside surface of ball, mobile top tray makes the outside surface of itself and ball tangent, grip device 3 and top tray is again adjusted after the angle of whirligig 4 screw setting, circularity detection device detects the displacement of grip device 3 and top tray, thus measures the circularity of ball.
Present embodiment is also provided with line slideway and fixture drive unit 1, line slideway is horizontally placed on board 6, two grip devices 3 are arranged on line slideway, fixture drive unit 1 is connected with two grip devices 3, also be provided with the propulsion system 2 driving whirligig 4 to rotate, whirligig 4 comprises catching.
As another embodiment, on the basis of a upper embodiment, the catching that present embodiment provides is inner concavity structure, can keep away the area reducing contact ball, reduce the wearing and tearing to sphere.
As another embodiment, on the basis of the second embodiment, the surface contacted with ball of the catching that present embodiment provides also is provided with sawtooth, increases the friction with ball contact portion, better drive ball to rotate.
As another embodiment, for reaching better technique effect, on the basis of the 3rd embodiment, the catching that present embodiment provides is elastic component.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; be understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any amendment made, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
