Abstract

The utility model provides a kit series tool used for clamping various cutting tools on an ordinary metal cutting machine. The utility model is characterized in that the original integral back cap is made into a back cap combining a back cap, steel balls and a retainer ring, and the original integral back cap is converted into a ball bearing type structure that the back cap is connected with the retaining ring through the steel balls. The utility model has the advantages of simple manufacturing, low cost and long service life, and simultaneously has the effects of flexible rotation, rapid cutting tool changing and convenient use.

Description

Universal quick changing clamp for boring milling and drilling

The utility model relates to a kind of complete series of tools that the various cutters of clamping are used on the common metal stock-removing machine, is a kind of boring, mills, drills through and use quick chuck.

The like product of producing both at home and abroad all is to be made of mother's cover, back of the body cap and folder the Knife tool at present, its weak point is that loading and unloading are inconvenient, and it is strict that back of the body cap and folder the Knife tool clamp the position restriction, and majority is to sit in the right seat, versatility is poor, clamps the position in case wearing and tearing just can not be used.The male cone (strobilus masculinus) domestic production of female cover be 7:24(50), can only use on the milling machine or on the boring and milling machine, can not on common boring machine and drilling machine, use, versatility is relatively poor.

The purpose of this utility model is above-mentioned weak point is improved, and providing a kind of can clamp fast, can unclamp fast again, and the boring that all can locate automatically of highly versatile and clamping or unclamp, mill, drills through and use quick chuck.

In order to achieve the above object, basic structure of the present utility model is to be made of mother's cover, back of the body cap, steel ball, straight pin, ring washer, folder the Knife tool, dog screw, on the back of the body cap that is characterized in connecting female cover and pressing from both sides the Knife tool a rotating back-up ring is set, can drives folder the Knife tool and realize loading and unloading fast.

Narrate embodiment according to accompanying drawing below.

Fig. 1 is the half sectional view of quick chuck structure.

Fig. 2 is along Figure 1A-A line full sectional view.

Fig. 3 is female cover half sectional view.

Fig. 4 is the half sectional view of combination back of the body cap.

Fig. 5 is the upward view of Fig. 4.

Fig. 6 is folder the Knife tool, dog screw are connected the position with female cover a front view.

Fig. 7 is the broken section vertical view of Fig. 6.

Shown in Fig. 1-7, connect on the back of the body cap 2 of female cover 1 and folder the Knife tool 6, a back-up ring free to rotate 5 is set, when this back-up ring 5 screws in the cannelure of folder the Knife tool 6, in the cannelure of folder the Knife tool a dog screw 7 is set, back-up ring screws in the cannelure, can locate automatically, and the screw 7 that is positioned blocks.At this moment pressing from both sides the Knife tool 6 can follow combination back of the body cap 2 and overlap to axially move on 1 mother and realize loading and unloading folder the Knife tool 6 fast.Back of the body cap 2 and female cover 1 are by being threaded togather, and back of the body cap 2 overlaps on 1 rotation mother can load and unload folder the Knife tool 6 less than a circle.Back-up ring 5 is to link together by steel ball 3 with back of the body cap 2, rotate flexibly, back-up ring 5 rotation in the cannelure of folder the Knife tool 6 can be located automatically less than 1/4 circle, the male cone (strobilus masculinus) of female cover 1 and the taper hole of machine tool chief axis are connected with Mo Shi 5.6, metric system 80,7:24(50) can satisfy common boring, mill, the needs of drilling machine, the inner conical surface of female cover 1 is that the 1:8 self-locking conical surface is connected radial location precision height with clamping tool, clamping is safe and reliable, assort a complete set of folder the Knife tool and can widen the range of work of these lathes, particularly on boring machine or milling machine, can finish boring, mill, bore, whole operations of tapping.

Its using method is: the mother's cover that chooses is fixed on the main shaft, transfer back of the body cap in position that mother puts, then folder the Knife tool is installed in the taper hole of female cover, back-up ring turns right, screw in the cannelure of folder the Knife tool, enclose the screw that is positioned less than 1/4 and block, can lock use to anticlockwise back of the body cap less than a circle again.When changing folder the Knife tool, the back of the body cap that turns left can unclamp less than a circle, and the back-up ring that turns left again encloses the screw that is positioned less than 1/4 and blocks, and folder the Knife tool unclamps automatically, finishes once and changes fast.

The utility model manufacturing process is simple, and cost is low, long service life.Because original whole back of the body cap is changed into combination back of the body cap back-up ring free to rotate, make folder the Knife tool not be subjected to put the restriction of clamped position mother, therefore rotate flexibly, it is fast to change cutter, and accurate positioning is easy to use.Simultaneously, because the improvement of male cone (strobilus masculinus) in female cover makes folder the Knife tool improve versatility again, also widened the range of work of lathe.

Claims

1, a kind of boring, mills, drills through and use quick chuck, constitute by mother's cover, back of the body cap, steel ball, straight pin, back-up ring, folder the Knife tool, dog screw, it is characterized in that: connect on the back of the body cap of female cover and folder the Knife tool a rotating back-up ring is set, can drive folder the Knife tool and realize quick the loading and unloading.

2, boring according to claim 1, mill, drill through and use quick chuck, it is characterized in that: in the cannelure of folder the Knife tool a dog screw is set, back-up ring screws in the cannelure, can locate automatically.
