Abstract

The utility model relates to a cramping apparatus, which is composed of a base, a positioning block, and an air cylinder. The positioning block is fixed on a support frame between the base and the air cylinder, and the end of the piston rod of the air cylinder is connected with a pressing block. The pressing block is movably combined with the positioning block. The cramping apparatus of the utility model can clamp keys from 3 to 9 for one time and simultaneously process the keys from 3 to 9. The work efficiency and processing precision can be improved. The positioning block uses special components to combine with alternate components, and the versatility is strong. Keys with different specifications and shapes can be processed. The utility model has the advantages of simple structure, convenient adjustment, low cost, and good practicality and can be matched with the machine tool for use.

Description

Key clamping-unit

The utility model relates to a kind of anchor clamps, the Key clamping-unit of especially a kind of numerical control milling machine for making key special use.

On existing traditional lathe, a kind of clamp body can only clamping one type key billet, when the key billet of other type of processing, the integral replacing clamp body, not only take a lot of work but also time-consuming, and the cost height; If processing double cog key then need carry out the secondary clamping, therefore, efficient is low, low precision.

The purpose of this utility model is to provide a kind of machining accuracy height, high efficiency and the lower Key clamping-unit of cost.

Technical solution of the present utility model is: a kind of Key clamping-unit, comprise base, locating piece and cylinder, it is characterized in that: locating piece is fixed on the support between base and the cylinder, and the tailpiece of the piston rod of cylinder is connected with briquetting, and this briquetting combines with the locating piece activity.

Described locating piece is made of sole piece and forward and backward type geosynclinal block, cooperates by geosynclinal block is movable between forward and backward type geosynclinal block and the sole piece, and is fixed by pressing plate, screw.

Below in conjunction with drawings and Examples the utility model is illustrated.

Fig. 1 is the utility model structural representation;

Fig. 2 is the A-A cutaway view of Fig. 1;

Fig. 3 is the locating piece structural representation;

Fig. 4 is that the B of Fig. 3 is to view;

Fig. 5 is the C-C cutaway view of Fig. 3.

By Fig. 1, Fig. 2 as seen, the Key clamping-unit of present embodiment is made of base 1, locating piece 2 and cylinder 3.Locating piece 2 is fixed on the support between base 1 and the cylinder 3, and the piston rod 3-1 of cylinder 3 end is connected with briquetting 4, under the effect of air pressure, stretches under the piston rod 3-1 and drives briquetting and press down, and makes briquetting 4 and locating piece 2 movable combinations.

Locating piece 2 (see figure 3)s are made of sole piece 2-1 and forward and backward type geosynclinal block 2-2,2-3.Cooperate by dovetail groove, dovetails activity between forward and backward type geosynclinal block 2-2,2-3 and the sole piece 2-1, and fix by pressing plate 2-4, screw 2-5.One side of locating piece 2 has screw 2-6, by being fixed on screw corresponding on base 1 support, the horizontal level of adjustable whole locating piece 2.

The both sides of forward and backward type geosynclinal block 2-2,2-3 correspondence vertically offer the hole slot 2-7 of some corresponding placement key billets (seeing Fig. 4, Fig. 5), so that can stack, add number simultaneously the key of identical tooth flower, tooth pitch.This forward and backward type geosynclinal block 2-2,2-3 can be according to length, width and the nose shape designs of processing key billet, make different type geosynclinal blocks, so as with the supporting use of common segment, adapt to processing needs to the key of different size shape.

For with the supporting use of numerical control milling machine for making key, the base of this Key clamping-unit is by screw and screw mandrel 5 thread connection, can be under the driving of stepping TV 6 along the gathering sill that is fixed on both sides, drive locating piece 2 and do upper and lower reciprocating motion, under the cutting of two-way milling cutter 7, can realize the processing (seeing Fig. 1, Fig. 2) of several the two-sided tartars of key.

Compared with prior art, the utlity model has following advantage:

1, clamp body and lathe have been carried out organic combination, make anchor clamps and lathe melt for One.

2, the disposable clamping of key billet can be processed 3-9 simultaneously key, has improved the worker Make efficient and machining accuracy.

3, clamp body is simple in structure, easy to adjust, cost is low, economical and practical.

4, highly versatile is by adjusting the processing of the applicable different size key of forward and backward type geosynclinal block.
