Abstract
The utility model discloses a taper-shank end mill chuck of a boring machine. The spindle of the boring machine is solid, thus a long bolt cannot pass through a spindle bolt to tension a tool like in a milling machine. If the tool is unreliably mounted on the spindle, the tool is influenced by the cutting force and vibration in cutting and is loosened and separated out from the spindle hole in the cutting process, and consequently, the tool is damaged and the workpiece becomes a waste. The taper-shank end mill chuck disclosed by the utility model comprises a chuck body (1), wherein one end of the chuck body is connected with a nut (4); a hole is formed at the center of the nut; an assembly hole is formed in the chuck body; a transition sleeve (3) is mounted in the assembly hole; a milling cutter taper shank (5) sequentially passes through the hole of the nut and is inserted into a taper hole of the transition sleeve; the milling cutter taper shank is tightly arranged in the transition sleeve through a screw (2); the taper shank of the chuck body is inserted into a taper hole of the spindle of the boring mill and tightly locked on the spindle through a flat pin. The taper-shank end mill chuck disclosed by the utility model is applied to vertical clamping of the milling cutter.
Description
technical field:
the utility model relates to a kind of boring machine circular cone handle end mill chuck.
background technology:
on boring machine, carry out Milling Process more bothersome, its reason is the difficulty of milling cutter clamping aspect.Because boring spindle is solid, can not as milling machine, from spindle hole, pass tension cutter by available stay bolt.If it is unreliable that cutter is installed at main shaft, in working angles, cutter is subject to the vibration in cutting force and cutting, makes cutter from spindle hole, become flexible or deviate from, and not only makes tool damage, but also can make workpiece become waste product.
utility model content:
the purpose of this utility model is to provide a kind of boring machine circular cone handle end mill chuck.
above-mentioned object realizes by following technical scheme:
a kind of boring machine circular cone handle end mill chuck, its composition comprises: collet body, described collet body one end is connected with nut, the cap heart of described nut has hole, described collet body has pilot hole, spacer shell is arranged in described pilot hole, milling cutter taper shank is inserted in the taper hole of described spacer shell through the hole of described nut successively, described milling cutter taper shank loads in described spacer shell by screw, the taper shank of described collet body inserts in boring spindle taper hole, by cotter pilotage, is locked on described main shaft.
described boring machine circular cone handle end mill chuck, the first half of described pilot hole is cylindrical shape, and the latter half of described pilot hole is truncated cone-shaped, and described spacer shell adopts Mohs cover.
described boring machine circular cone handle end mill chuck, described spacer shell adopts taper sheath, and the tapering of described taper sheath is between 5:24 to 3:8.
beneficial effect:
1. the utility model is simple in structure, and clamping is firm, and tool changing is rapidly convenient, and applicability is strong.According to the size of milling cutter taper shank size, change the spacer shell of different taperings, guarantee that it coordinates closely.
2. spacer shell tapering of the present utility model is large, and self-lock ability is poor, is convenient to handling.
accompanying drawing explanation:
accompanying drawing 1 is structural representation of the present utility model.
the specific embodiment:
embodiment 1:
a kind of boring machine circular cone handle end mill chuck, its composition comprises: collet body 1, described collet body one end is connected with nut 4, the cap heart of described nut has hole, described collet body has pilot hole, spacer shell 3 is arranged in described pilot hole, milling cutter taper shank 5 is inserted in the taper hole of described spacer shell through the hole of described nut successively, described milling cutter taper shank loads in described spacer shell by screw 2, the taper shank of described collet body inserts in boring spindle taper hole, by cotter pilotage, is locked on described main shaft.
embodiment 2:
according to the boring machine circular cone handle end mill chuck described in embodiment 1, the first half of described pilot hole is cylindrical shape, and the latter half of described pilot hole is truncated cone-shaped, and described spacer shell adopts Mohs cover.
embodiment 3:
according to the boring machine circular cone handle end mill chuck described in embodiment 1, described spacer shell adopts taper sheath, and the tapering of described taper sheath is between 5:24 to 3:8.
Claims (3)
1. a boring machine circular cone handle end mill chuck, its composition comprises: collet body, it is characterized in that: described collet body one end is connected with nut, the cap heart of described nut has hole, described collet body has pilot hole, spacer shell is arranged in described pilot hole, milling cutter taper shank is inserted in the taper hole of described spacer shell through the hole of described nut successively, described milling cutter taper shank loads in described spacer shell by screw, the taper shank of described collet body inserts in boring spindle taper hole, by cotter pilotage, is locked on described main shaft.
2. boring machine circular cone handle end mill chuck according to claim 1, is characterized in that: the first half of described pilot hole is cylindrical shape, and the latter half of described pilot hole is truncated cone-shaped, and described spacer shell adopts Mohs cover.
3. boring machine circular cone handle end mill chuck according to claim 1 and 2, is characterized in that: described spacer shell adopts taper sheath, and the tapering of described taper sheath is between 5:24 to 3:8.
