Abstract
The utility model discloses a base used for triangular prism angle detection. The base used for triangular prism angle detection comprises a bottom plate. A baffle block is fixedly arranged on the edge of one end of the bottom plate. The baffle block is provided with a straight edge. Three steel balls are fixedly arranged on the surface, which is on one side of the straight edge, of the bottom plate. The three steel balls are distributed in accordance with a triangle. The contact points of the three steel balls and a product are in one plane. According to the utility model, the base used for triangular prism angle detection has the advantages of accurate detection and no damage to the finish of the prism surface, thus the product yield is improved.
Description
Technical field
The utility model relates to a kind of angle device of measuring high precision prism product, specifically is that a kind of detection prism angle is used pedestal.
Background technology
The utility model provides a kind of angle that is used to measure high precision prism product.Utilize this pedestal, reduce the surface of optical articles and the surface of contact of pedestal to greatest extent, the surface smoothness of protection optical articles.Simultaneously, use 3 principles that determine a face, reduce the erroneous judgement that angular error caused the product angular accuracy because of pedestal itself.Enhance productivity, reduce useless loss rate.
The utility model content
The utility model provides a kind of detection accurate, does not destroy prism surface smooth finish, improves the detection prism angle of the qualification rate of product and uses pedestal.
The utility model technical solution problem provides following scheme:
A kind of detection prism angle is used pedestal; Comprise base plate; It is characterized in that: be installed with block on the edge of an end of said base plate, said block has a straight flange, and the backplate surface of a side of said straight flange is installed with three steel balls; Said three steel balls distribute according to triangle, and the contact point of said three steel balls and product in one plane.
Said base plate adopts the material of sheet glass or other any surface finish.
The utility model is used pedestal for the prism angle, is made up of one of the sheet glass that is of moderate size and three steel balls, and steel ball is triangular arranged and is fixed on the sheet glass with pitch; In fixation procedure, detect with standard jig, the contact point of guaranteeing three steel balls and product is on a surface level.Earlier adjust angular instrument with the angular templet of standard during detection, the one side with tested prism is placed on the steel ball then, and another side is over against angular instrument; Use comparative measurement method, measure the angle tolerance of this prism.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Referring to accompanying drawing, a kind of detection prism angle is used pedestal, comprises base plate 1; Be installed with block 2 on the edge of one end of said base plate 1; Said block 2 has a straight flange, and the backplate surface of a side of said straight flange is installed with three steel balls 3, and said three steel balls 3 distribute according to triangle; The contact point of said three steel balls 3 and product in one plane, said base plate 1 adopts the material of sheet glass or other any surface finish.
Claims (2)
1. a detection prism angle is used pedestal; Comprise base plate; It is characterized in that: be installed with block on the edge of an end of said base plate, said block has a straight flange, and the backplate surface of a side of said straight flange is installed with three steel balls; Said three steel balls distribute according to triangle, and the contact point of said three steel balls and product in one plane.
