Description
Technical field
The utility model belongs to technical field of mechanical manufacturing equipment, concretely relates to a kind of numerically controlled lathe automatic drilling
Collet.
Background technique
Low-cost type CNC lathe is evolved by center lathe, and knife-carrier before generally four stations, operation mode is by numerical control
System control feeding, it is automatic to process.It drills, has no difference with drilling on center lathe, still on low-cost type CNC lathe
It relies on and drill bit is installed on tail stock, drilling processing is carried out by rotation tailstock handwheel.Because tailstock does not have auto-feed function,
By manual length feed, the not only large labor intensity of operator, production efficiency is low, and the depth in the hole drilled out is not allowed yet
It is easy to control.
The bulk article that class with holes is such as processed with numerically controlled lathe still needs to pay a large amount of manual labor, and size does not have
The characteristics of method controls well, does not also show numerically controlled lathe high degree of automation.
Application number CN201521001677.3, patent name are the patent disclosure of low-cost type CNC lathe automatic drilling fixture
A kind of to be used for low-cost type CNC lathe automatic drilling fixture, the utility model solves low-cost type CNC lathe because can not be automatic
Programming and Manual drilling low efficiency, the problem of low precision, are used for economical four stations numerically controlled lathe automatic drilling fixture, set folder
Tool is made of collet seat and taper hole set, and collet seat is mounted on Tool-rest of Numerical Control Lathe, and blending bolt is pressed on knife rest, taper hole set
With collet seat by being welded together, taper hole set is the taper hole with Morse's taper, and taper hole covers tail portion and has U-lag, U-shaped
Slot is used to fix the tang of taper-shank drill, prevents drill bit because of Forced rotation, and taper hole covers the perforation of tail portion U-lag, is conducive to take out and bore
Head, taper hole, which is put on, processes a plane A, can use dial gauge centering boring grab, be overlapped taper hole axis with main-shaft axis, taper hole
Set left side outer circle is used to centering taper hole and main-shaft core, keeps taper hole and machine tool chief axis axis concentric, datum level B and knife rest on collet seat
Bottom surface fitting guarantees that bit central height and main-shaft axis are contour；Its there are the problem of for the fixture include collet seat and taper hole
Set, its structure is complicated, and collet seat and taper hole set are often difficult to successively machine-shaping, is being welded after being individually produced
Assembled formation is displaced after resulting in the two to assemble, and the horizontal plane of the axis and collet seat that cover taper hole, which generates, to be reversed, in turn
It is difficult to in the axis and main-shaft axis that clamping to cutter back taper hole covers；In addition, taper-shank drill is intended to take after being packed into taper hole set
Taper-shank drill just needs to be inserted into taper hole set tail portion U-lag using wedge block out, and tap can be drawn off, taper-shank drill
It is very inconvenient to take out.
Summary of the invention
The purpose of the utility model is to provide a kind of numerically controlled lathe automatic drilling collet,.
In order to solve the above technical problems, purpose of the utility model is realized as follows:
A kind of numerically controlled lathe automatic drilling collet, including collet, the collet be it is rectangular-shaped, the collet is solid by bolt
Due to the knife rest of numerically controlled lathe；
Described collet one end offers mohs tapered bore, and the other end offers a bolt hole coaxial with the mohs tapered bore,
Screwing a bolt in the bolt hole, the collet offers a locating slot being connected to the mohs tapered bore its inner terminal,
The axis of the vertical mohs tapered bore of the locating slot, the locating slot run through the collet, and taper-shank drill can be mounted directly
In the mohs tapered bore, the taper-shank drill tail portion is positioned by the locating slot；
Bolt described in turn can be such that bolt head enters in the locating slot.
Preferred embodiment on the basis of above scheme and as above scheme: its seamed edge of the collet is arc-shaped.
Preferred embodiment on the basis of above scheme and as above scheme: the jacket material is 40Cr steel alloy.
Preferred embodiment on the basis of above scheme and as above scheme: the collet is at end where the bolt hole
Portion has extended axially outwardly a cylinder boss, and the bolt hole runs through the cylinder boss.
Preferred embodiment on the basis of above scheme and as above scheme: the locating slot is kidney-shaped.
Compared with the prior art, the utility model has prominent and beneficial technical effects that:
1, mohs tapered bore is directly opened in collet, collet be it is rectangular-shaped, in this way can directly to regular turning tool it is the same to
Clamping on cutterhead, structure is simple, easy for installation, and clamping is reliable, two opposite plane of rectangular structure and cutterhead clamping face paste
Close, can good guarantees bit central height and main-shaft axis it is contour, the adjacent plane of another two is used for dial gauge centering
Fixture is overlapped mohs tapered bore axis with main-shaft axis, and positioning accuracy is high.
2, the new technique is widely portable to the processing of low-cost type CNC lathe automatic drilling.
3, fixture is easy to adjust.
4, the setting of bolt and bolt hole is so that the disassembly of taper-shank drill is more convenient, it is only necessary to turn bolt make its to
The movement of locating slot direction can eject taper-shank drill.
