Abstract

The utility model provides a measuring base. Regarding the utility model, a steel plate (1) and another steel plate (2) are joined together. The angle beta between the steel plate (1) and the steel plate (2) is the same with the angle of a V-shaped guide surface to be measured. At least three steel balls (3) are welded on the steel plate (1); at least two steel balls are welded on the steel plate (2). The utility model can be an alternative to a V-shaped frock, and adopts the method that surfaces are replaced with points, and processing of a V-shaped surface is not required. The utility model has the advantages that the utility model is easy to be manufactured; the cost is low, and the measurement results are not subject to accuracy of the angle to be measured.

Description

A kind of measurement pedestal

Technical field:

Employed frock technical field when the utility model relates to measuring equipment parts form and position tolerance, particularly a kind of measurement pedestal.

Background technology:

At present, the measurement of paralleism between V-type rail face and other machined surface in the prior art adopts the frock with V-type face to come auxiliary detection usually, and V-type face processing technology complexity, high to the crudy requirement, angle precision is very big to the measurement result influence.

The utility model content:

In order to solve the problem of above-mentioned existence, the utility model provides a kind of measurement pedestal, and this measurement frock making easily, does not need to process the V-type face, and not high to the angle accuracy requirement.

The technical scheme that the utility model adopted is: described a kind of measurement pedestal, and its a steel plate and b steel plate link together, and β ° of angle between a steel plate and the b steel plate is consistent with the angle between the tested V-type rail face; Be welded with at least three steel balls on an a steel plate therein, on another piece b steel plate, be welded with at least two steel balls.

Described a steel plate and b steel plate weld together.

The utility model is with using traditional V-type face frock similar, contains the V-type rail face with the angle of pedestal, and the V-type face of steel ball and guide rail is adjacent to.Wherein three steel balls on the block plate can form 3 contact points when being adjacent to guide pass, determine a plane at 3, can replace a machined surface of V-type frock; Two steel balls on another part steel plate form 2 contact points when being adjacent to guide pass, these 2 angles with guide pass are determined a face jointly, can replace another machined surface of V-type frock.Angle between two block plates and five positions of steel ball on two block plates do not need strict requirement.Because the utility model adopts with the method for point for face, does not need to carry out the processing of V-type face, have and make advantage easy, with low cost and that measurement result is not influenced by the angle precision.

Fig. 2 is that the P of Fig. 1 is to view;

Fig. 3 is that the K of Fig. 1 is to view;

Fig. 4 is a user mode synoptic diagram of the present utility model.

Embodiment:

As shown in Fig. 1,2,3, the utility model comprises a steel plate 1, b steel plate 2, steel ball 3; Be β ° of angle between a steel plate 1 and the b steel plate 2 and weld together, or make an integral body with other method, the consistent or basically identical of angle between β ° of angle and the tested V-type rail face is as long as approach angle between the tested V-type rail face; On a steel plate 1, be welded with at least three steel balls 3, three steel balls 3 form 3 contact points not on same straight line, determine a plane at 3, be welded with at least two steel balls 3 on b steel plate 2, the position of steel ball 3 on a steel plate 1 and b steel plate 2 do not need strict requirement.

As shown in Figure 4, when the utility model uses, angle with pedestal contains the V-type rail face, guarantee that 5 steel balls all are adjacent to guide pass, dial gauge or clock gauge directly are fixed on the pedestal, or affixed by other connection means and pedestal, after indicator presses measurement face, then along guide rail mobile foundation, reading numerical values.Must guarantee that at moving process five steel balls all are adjacent to guide pass.

Claims
