The crystal prism auxiliary machining device has the advantages of accurate angle control and high detection qualified rate.
Description
Technical field
The utility model relates to the production equipment of prism and manufactures the auxiliary machining device in field, particularly crystal prism.
Background technology
Prism is the polyhedron that transparent material (as glass, crystal etc.) is made.In optical instrument, application is very wide.Prism can be divided into several by its character and purposes.For example, complex light is decomposed into " dispersing prism " of spectrum in spectral instrument, conventional is equilateral prism; In the instruments such as periscope, binocular, change the travel direction of light, thereby adjust the title " total reflection prism " of its image space, generally all adopt right-angle prism, take prism as example, according to law of refraction light process prism, by twice to bottom surface deviation, the angle q of emergent ray and incident ray is called deflection angle. and its size is determined by refractive index n and the incidence angle i of prism medium. when i is fixedly time, the light of different wave length has different deflection angles, in visible ray, deflection angle maximum is purple light, and minimum is ruddiness.
Because prism is not in most cases a kind of polyhedron of symmetry, how each face being carried out to sanding and polishing makes it adjacent two sides to have angle is accurately a problem of extremely difficult solution, in prior art, traditional detection method is, prism is unloaded from milling tools, then by angular instrument or employing optical reflection principle, carry out the angle of accurate Calculation two adjacent surfaces, this detection method is time-consuming takes a lot of work, in most cases, prism is by chemical adhesive, prism to be bonded on milling tools, the process exception difficulty unloading, therefore how to develop a kind of high-precision for controlling the instrument of angle of the adjacent surface of prism, be very urgently and very to there is realistic meaning.
Utility model content
The utility model provides a kind of angle precise control, detects the auxiliary machining device of the crystal prism that qualification rate is high.
The technical scheme that the utility model provides is: a kind of auxiliary machining device of crystal prism, comprise disc-shaped base, it is characterized in that, the upper surface of described pedestal is fixedly connected with one for the oblique circular cylinder of fixed crystal prism, the one side that described oblique circular cylinder contacts with pedestal is oblique section, the one side that described oblique circular cylinder contacts with crystal prism is for circular, described oblique section and the angle of normal section are 8～15 °, on described oblique circular cylinder, be evenly arranged several the first counterweight holes, on described pedestal, be evenly distributed with several the second counterweight holes.
In the auxiliary machining device of above-mentioned crystal prism, described oblique section and the angle of normal section are 11 °.
In the auxiliary machining device of above-mentioned crystal prism, the center of the upper surface of described pedestal is provided with bolt, and the center of the normal section of described oblique circular cylinder is provided with the bolt hole mating with described bolt.
In the auxiliary machining device of above-mentioned crystal prism, the first described counterweight hole is 4, and the number in the second described counterweight hole is 4.
In the auxiliary machining device of above-mentioned crystal prism, the lower surface of described pedestal is provided with the connecting shaft hole for being fixedly connected with the rotating shaft of peripheral hardware, the end of the rotating shaft of described peripheral hardware is provided with external screw thread, and described connecting shaft hole inside is provided with the internal thread mating with the external screw thread of the end of described rotating shaft.
In the auxiliary machining device of above-mentioned crystal prism, described oblique circular cylinder is that stainless steel material is made.
The utility model is fixedly sleeved in disc-shaped base by oblique circular cylinder, because oblique section contacts with pedestal, the i.e. end face parallel with normal section of the one side of the non-oblique section of oblique circular cylinder so, gone into the angle with horizontal direction with setting, operating personnel are when needs polishing, only need to the prism with certain angle be bonded on the end face of non-oblique section by chemical adhesive, by polishing machine, carry out polishing, guarantee that polishing end face out meets the requirement of product, production precision is high, because the oblique circular cylinder of this programme is asymmetric metallic object, therefore on pedestal and oblique circular cylinder, be equipped with counterweight hole, can regulate accurately the center of gravity of this auxiliary machining device, prevent gravity centre distribution inequality in process and produce excessive stress deformation.
