Abstract

The utility model provides process equipment capable of ensuring machining verticality of gem stick end faces. The process equipment comprises a cylindrical fixed seat and is characterized in that a plurality of axially extending V-shaped grooves are arranged on the circumferential surface of the fixed seat; the two ends of each V-shaped groove penetrate through two end faces of the fixed seat; and two side walls of each V-shaped groove are respectively vertical to the two end faces of the fixed seat. The process equipment has the following beneficial effects that: the verticality between the two side walls of the V-shaped grooves and the two end faces of the fixed seat is more convenient to control during machining the V-shaped grooves and the verticality of the V-shaped grooves can be conveniently checked and corrected by an angle square, thus improving the verticality of the gem stick end faces; secondly, the process equipment can adapt to gem sticks with various cross section dimensions, and during machining, the gem sticks only need to cling to the two side walls of the V-shaped grooves, thus lowering the machining cost; and meanwhile, fit tolerance between the gem sticks and the positioning holes in the prior art is avoided, thus further improving the machining verticality of the gem stick end faces.

Description

Can guarantee the frock of gem stick end face processing perpendicularity

Technical field

The utility model relates to a kind of frock of processing gem plane rod end, relates in particular to a kind of frock that can guarantee gem stick end face processing perpendicularity.

Background technology

In thick, thin, the correct grinding and polishing processing of elongated rod type jewel end face, must guarantee the perpendicularity of gem stick end face.Referring to Fig. 5, Fig. 6, the frock of existing a kind of processing gem plane rod end, it comprises base plate 6 and is fixed on the cylindrical holder 7 on the base plate; Holder 7 axially on be drilled with some locating holes that are used for fixing gem stick, the axis normal of locating hole is in the end face of holder 7, during use; Gem stick 5 is inserted in the locating hole of holder; The shape of cross section of gem stick 5 matches with the shape of cross section of locating hole, and an end of gem stick 5 extends the end face of holder, then the extension end face of gem stick 5 is processed; When the extension end face of gem stick is concordant with the end face of holder, promptly accomplish the end face processing of gem stick.There is following problem in existing this frock:

1, each locating hole on the holder is to form through the mode of holing, and is difficult to guarantee that the axis of each locating hole keeps vertical with the end face of holder, thereby has reduced the perpendicularity after the processing of gem stick end face.

2, after gem stick is inserted in the locating hole, there is fit tolerance between gem stick and the locating hole, so can produces between the end face of the axis of gem stick and holder, thereby reduced the perpendicularity after the processing of gem stick end face.

3, because the shape of cross section of the locating hole on the holder must match with the shape of cross section of gem stick, therefore, different frocks must be provided, increase processing cost to the gem stick of different size.

4, for the too small or excessive locating hole in aperture, the perforation processing difficulty is very big on the blocked up holder of thickness, has increased processing cost.

The utility model content

The technical problem that the utility model solves is: a kind of frock that can guarantee gem stick end face processing perpendicularity is provided, and this frock can also be used for the processing of different size gem stick end face simultaneously.

The technical scheme of the utility model is: a kind of frock that can guarantee gem stick end face processing perpendicularity; Comprise columniform holder; It is characterized in that; Have some V-type grooves that extend vertically on the periphery of said holder, the both ends of the surface of holder are all run through at the two ends of each V-type groove, and the two side of each V type groove is respectively perpendicular to the both ends of the surface of holder.

The center of the both ends of the surface of said holder has counterbore, and the bottom of each counterbore is provided with conical bore, and two conical bores are positioned on the axis of holder.

The beneficial effect of the utility model is: at first; Existing for the locating hole that forms through bore mode in the prior art; V-type groove work in-process in the utility model is more convenient for controlling the perpendicularity between the both ends of the surface of two side and reservation of V type groove, and can check V type groove perpendicularity with angle square easily, and revises; Thereby improved the perpendicularity of gem stick end face; And locating hole of the prior art is not easy to revise, and its cross sectional dimensions also can change after revising, and can not cooperate with gem stick; Secondly, the utility model can adapt to the gem stick of various cross sectional dimensions, adds man-hour, only need the two side of gem stick and V-type groove be close to get final product, and has reduced processing cost; Also avoided simultaneously having fit tolerance between the gem stick and locating hole in the prior art, further improved the perpendicularity of gem stick end face processing.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is described further:

Referring to Fig. 1, Fig. 2; A kind of frock that can guarantee gem stick end face processing perpendicularity comprises columniform holder 1, has some V-type grooves 2 that extend vertically on the periphery of said holder 1; Two end faces of holder 1, i.e. end face 1a and end face 1b are all run through in the two ends of each V-type groove 2.And the sidewall 2a of each V type groove 2 and sidewall 2b are respectively perpendicular to the end face 1a and the end face 1b of holder 1.The quantity of V-type groove 2 is decided according to the diameter of cylindrical holder 1, and the quantity of the bigger V-type groove 2 that it can be established of diameter is many more, and the quantity of the V-type groove 2 in the present embodiment is ten.The end face 1a center of said holder 1 has counterbore 3, and the bottom of counterbore 3 is provided with conical bore 3 ', and the end face 1b center of holder 1 has counterbore 4, and the bottom of counterbore 4 is provided with conical bore 4 ', and conical bore 3 ' is positioned on the axis of holder 1 with conical bore 4 '.Counterbore 3 in the middle of the holder both ends of the surface can reduce the center of gravity that adds man-hour with counterbore 4, alleviates the weight of holder 1 simultaneously, and conical bore 3 ' is used for cooperating with the thimble of lathe with conical bore 4 '.

Referring to Fig. 3, Fig. 4; The utility model is to use like this: the utility model can adapt to the gem stick of various cross sectional dimensions; Only need are close to the gem stick 5 and the V-type groove two side of holder 1 and are adhesively fixed; Can avoid having fit tolerance between the gem stick and locating hole in the prior art, avoid too small, excessive, blocked up because of the locating hole aperture in the punching process in the prior art simultaneously, the difficulty of processing of the perpendicularity of locating hole and end face; Reduce processing cost, improved the perpendicularity of gem stick end face processing.
