Abstract

The invention discloses a multi-cutter cutting jig which comprises a jig body and a part, wherein a part clamping groove for fixedly clamping the part is formed in the upper end of the jig body, and a plurality of grooves are formed in the part clamping groove; according to the invention, the grooves are dug on the sticking surfaces of the clamping grooves of the jig, and the minimum contact surface can be achieved by accurately calculating the machining allowance of the prism with high precision, so that the contact area between the prism and the jig is reduced as much as possible, and the prism is only contacted with the wire grooves of the parts which are not dug in the prior art from the original whole surface contact, so that the probability of scratching the prism is reduced, and the generation of defective products is reduced; the grooving part is filled with the mixed wax that is located between tool and the prism, carries out fixed stay to the prism through mixed wax, makes the prism clamp in the tool more firmly, conveniently processes the prism, is favorable to improving the precision of prism processing.

Description

Multi-cutter cutting jig

Technical Field

The present invention relates to a cutting jig, and more particularly to a multi-blade cutting jig.

Background

Prism, a transparent object enclosed by two intersecting planes that are not parallel to each other, for splitting or dispersing light beams. The prism is a polyhedron made of transparent materials (such as glass, crystal and the like). The method is widely applied to optical instruments. The prism can be divided into several kinds according to its properties and uses. For example, in spectroscopy instruments, a "dispersive prism" which decomposes the composite light into a spectrum, more commonly an equilateral triangular prism; the so-called "total reflection prism" for changing the proceeding direction of light in periscope, binocular telescope and other instruments so as to adjust the imaging position is generally a right-angle prism.

In the cutting production process of the prism, the prism needs to be clamped and fixed by using a jig. But present tool draw-in groove and prism are laminated completely, scrape colored prism easily like this when clamping, produce punctiform or linear streak mar on making the prism, have improved the defective products production rate.

Disclosure of Invention

In order to overcome the defects of the prior art, the invention provides a multi-cutter cutting jig, wherein grooves are dug on the jig clamping groove veneers, the contact area between a prism and the jig is reduced, and the prism is only contacted with a wire groove at the part which is not dug from the original whole surface contact to the current time, so that the probability of scratching the prism is reduced, and the generation of defective products is reduced.

In order to solve the technical problems, the invention provides the following technical scheme:

the utility model provides a multitool cutting jig, includes tool body and part, the upper end of tool body is provided with the part draw-in groove that is used for the fixed part that clamps, be provided with a plurality of recesses in the part draw-in groove.

As a preferred technical scheme of the invention, grooves are formed in the two side walls and the bottom end of the part clamping groove.

As a preferred technical scheme of the invention, the groove is filled with mixed wax positioned between the jig body and the part.

Compared with the prior art, the invention can achieve the following beneficial effects:

according to the invention, the grooves are dug on the sticking surfaces of the clamping grooves of the jig, and the minimum contact surface can be achieved by accurately calculating the machining allowance of the prism with high precision, so that the contact area between the prism and the jig is reduced as much as possible, and the prism is only contacted with the wire grooves of the parts which are not dug in the prior art from the original whole surface contact, so that the probability of scratching the prism is reduced, and the generation of defective products is reduced; the grooving part is filled with the mixed wax that is located between tool and the prism, carries out fixed stay to the prism through mixed wax, makes the prism clamp in the tool more firmly, conveniently processes the prism, is favorable to improving the precision of prism processing.

Drawings

FIG. 1 is a schematic structural view of the present invention;

wherein: 1. a jig body; 2. a part; 3. a part clamping groove; 4. and (4) a groove.

Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are described herein for the purpose of illustration and explanation and not limitation.

Referring to fig. 1, the multi-cutter cutting jig includes a jig body 1 and a part 2, a part slot 3 for fixedly clamping the part 2 is disposed at an upper end of the jig body 1, and a plurality of grooves 4 are disposed in the part slot 3.

Both sides wall and the bottom of part draw-in groove 3 all are provided with recess 4, and recess 4 is provided with three groups at least, can reduce the area of contact of prism and tool as far as.

The groove 4 is filled with mixed wax between the jig body 1 and the part 2.

Specifically, the grooves 4 are dug on the veneers of the part clamping grooves 3 of the jig body 1, and the size, the number and the position of the grooves 4 can be determined by accurately calculating the machining allowance of the prism with high precision, so that the contact area of the prism and the jig is reduced as much as possible, and the prism is only contacted with a wire groove of a part which is not dug by the original whole surface contact, so that the probability of scraping the prism is reduced, and the generation of defective products is reduced; the mixed wax that is located between tool and the prism is filled to recess 4 intussuseption, carries out fixed stay to the prism through mixed wax, makes the prism clamp in the tool more firmly, conveniently processes the prism, is favorable to improving the precision of prism processing.

The embodiments of the present invention are not limited thereto, and according to the above-described embodiments of the present invention, other embodiments obtained by modifying, replacing or combining the above-described preferred embodiments in various other forms without departing from the basic technical idea of the present invention by using the conventional technical knowledge and the conventional means in the field can fall within the scope of the present invention.
