Abstract
A quick-change cutter comprises a chuck, a sliding sleeve and a straight shank cutter, wherein the tail part of the chuck is a taper shank, the head part of the chuck is a circular sleeve, two taper holes are formed in the side wall of the sleeve, steel balls are arranged in the taper holes, the sliding sleeve is arranged outside the sleeve, the straight shank cutter is arranged in an inner hole of the sleeve, a pit corresponding to the steel balls is formed in the straight shank, and a limiting check ring is arranged on the sliding sleeve. The utility model is suitable for a processing porous work piece on the drilling machine, the tool changing is convenient quick, shortens the assistance time, improves the work efficiency, and the dop can be general moreover, and the preparation of straight shank cutter is simplified, can reduce the processing cost.
Description
Technical field
The utility model relates to a kind of quick change cutter that is used for carrying out on the drilling machine hole processing.
Background technology
The processing master operation of cylinder cover for diesel engine is the processing in hole, and some general holes of degree requirement, position are arranged on the drilling machine usually and process, because the hole is more on the cylinder head, so tool changing is more frequent.Usually cutter is that Morse taper shank directly is contained on the machine tool chief axis, with specific purpose tool cutter is pulled down from the spindle hole of lathe during tool changing, and then is loaded onto another kind of cutter.Like this, tool changing bothers on the one hand, and non-cutting time is long, because each cutter all has Morse taper shank, and cost of manufacture is higher, the expense that cutter consumes when therefore processing cylinder head is also higher on the other hand.
The utility model content
The purpose of this utility model is to provide a kind of tool changing convenient and swift, can reduce again the cutter cost of manufacture the quick change cutter.
The technical solution of the utility model is: the quick change cutter is provided with a quick change dop, the afterbody of dop is the taper shank that has Morse's taper, the head of dop is a circular sleeve, be arranged with two taper holes on the sleeve lateral wall, a steel ball is respectively arranged in the taper hole, and sleeve is provided with the sliding sleeve that is slidingly matched with it outward, and sliding sleeve has a ring cavity between end of sleeve openings and sleeve, the staight shank cutter is installed in the sleeve endoporus, and the staight shank of this cutter is provided with the pit corresponding with above-mentioned steel ball.
Described sleeve is provided with the spacing back-up ring of twice, and spacing back-up ring can adopt elastic spring.
Taper shank with the quick change dop during work inserts in the lathe spindle hole, the left hand sliding cover that makes progress, make the re-entrant portion of its port arrive the steel ball position, the right hand inserts the staight shank of cutter in the sleeve of dop at the bottom of the hole, and this moment, steel ball moved outward, unclamp left hand then, sliding sleeve is because of the deadweight extruding steel ball that glides, and rotary cutter simultaneously is absorbed in the pit on the cutter staight shank steel ball, so the rotation of machine tool chief axis is passed to cutter by dop, steel ball, just machinable workpiece.During tool changing, sliding cover on the left hand, the right hand is rotary cutter slightly, and steel ball moves outward, just can take out cutter, loads onto another cutter subsequently.The spacing back-up ring of twice on the sleeve plays the position-limiting action to sliding sleeve, makes operation more convenient reliable.The tool changing of this kind structure is convenient and swift, even can not shut down the replacing cutter, shortens non-cutting time, improve working (machining) efficiency, and dop can be general, and various cutters are made staight shank, makes and simplifies, and cuts down finished cost.
Description of drawings
Accompanying drawing is the utility model structural representation.
The specific embodiment
As figure, the afterbody of quick change dop 1 has No. 3 taperings of Mohs, head is a circular sleeve, be arranged with two taper holes on the sleeve lateral wall, a steel ball 3 is respectively arranged in the taper hole, sleeve is provided with the sliding sleeve 4 that is slidingly matched with it outward, sliding sleeve has a ring cavity 5 between end of sleeve openings and sleeve, staight shank cutter 6 is installed in the sleeve, and the staight shank of cutter is provided with the pit corresponding with steel ball, and the spacing back-up ring 2 that the twice steel wire makes is set on the sleeve.
Claims (2)
1, a kind of quick change cutter, it is characterized in that being provided with a quick change dop, the afterbody of dop is the taper shank that has Morse's taper, the head of dop is a circular sleeve, is arranged with two taper holes on the sleeve lateral wall, and a steel ball is respectively arranged in the taper hole, sleeve is provided with the sliding sleeve that is slidingly matched with it outward, sliding sleeve has a ring cavity between end of sleeve openings and sleeve, the staight shank cutter is installed in the sleeve endoporus, and the staight shank of this cutter is provided with the pit corresponding with above-mentioned steel ball.
2, by the described quick change cutter of claim 1, it is characterized in that described sleeve is provided with the spacing back-up ring of twice.
