Abstract
The utility model relates to a milling cutter clamping device. A clamping head is provided with a first axial stepped hole; a plurality of cutter handle clamping grooves are uniformly distributed in the conical surface section of the clamping head; a support body is provided with a second stepped hole, and consists of a first straight hole, a second straight hole and a conical hole; the cylindrical section of the clamping head extends into the second straight hole of the support body, and is limited by the stepped surface of the second stepped hole; the peripheral surface of the cylindrical section of the clamping head is provided with a bulge; the second straight hole of the support body is provided with a slide groove; when the cylindrical section of the clamping head extends into the second straight hole, the bulge is inserted into the slide groove so as to form slide fit; one end of a connecting rod passes through stepped holes in the clamping head, the connecting rod is in threaded connection with the first straight hole, and passes through the first straight hole externally; the other end of the connecting rod is limited by the stepped surface of the first stepped hole in the clamping head; the connecting rod is also in threaded connection with the first straight hole. According to the milling cutter clamping device, a cutter head can be axially and peripherally positioned so as to guarantee the reliability of the milling cutter in operation.
Description
Technical field
The utility model relates to a kind of milling cutter clamping device.
Background technology
Common milling fixture is to fit mutually by the interior inclined-plane of locking nut and the outer inclined-plane of spring chuck, and screwed by locking nut.The differential seat angle producing due to its two internal and external threads fit clearance, can not be fitted completely in two inclined-planes, compression area accounts for 2/3rds of binding face, stressed irregular, serious wear, so reduced clamping force and the centering precision of chuck, make cutter holding not firm, easily fall cutter, also increased circular runout and the damage spring chuck of milling cutter.In addition, this structure in use often can be blocked spring chuck, can not successfully exit; will be with beaing vibrations or spring clip cover could being taken out with instrument prying and pulling; inconvenient operation, affects operating efficiency, also easily machine tool chief axis and fixture is caused to certain damage.
Summary of the invention
For above-mentioned technical problem, the utility model provides a kind of energy milling cutter clamping device, and the utility model can make cutter head axially and circumferentially all can obtain fine location, the reliability while guaranteeing milling cutter work.
The technical scheme solving the problems of the technologies described above is as follows:
Milling cutter clamping device, it comprises chuck, supporter and connecting rod, chuck is comprised of conical surface section and cylindrical section, chuck is provided with axial first step hole, in the conical surface section of chuck, be evenly distributed with a plurality of handle of a knife clip slots, described supporter is provided with second step hole, this second step hole is by the first straight hole, the second straight hole and taper hole form, the second straight hole is between the first straight hole and taper hole, the cylindrical section of chuck is spacing by the step surface in second step hole after extending in the second straight hole of supporter, the periphery of the cylindrical section of described chuck is provided with projection, in the second straight hole of described supporter, be provided with chute, when the cylindrical section of chuck extend in the second straight hole, described projection is inserted in chute and forms and be slidably matched, after one end of described connecting rod is passed in the stepped hole on chuck, be threaded with the first straight hole on supporter and pass the outside of the first straight hole, the other end of connecting rod is spacing by the step surface in the first step hole on chuck, connecting rod is also threaded with the first straight hole.
The end that described connecting rod reaches outside the first straight hole is provided with hole, inserts a push rod in this hole.
Adopted such scheme, during use, milling cutter is stuck in the upper handle of a knife clip slot of folder, spacing by the step surface in second step hole after the cylindrical section of chuck being extend in the second straight hole of supporter, after one end of connecting rod is passed in the stepped hole on chuck, be threaded with the first straight hole on supporter and pass the outside of the first straight hole, the other end of connecting rod is spacing by the step surface in the first step hole on chuck.By connecting rod by collet axis to being locked on supporter.The periphery of the cylindrical section of described chuck is provided with projection, in the second straight hole of described supporter, be provided with chute, when the cylindrical section of chuck extend in the second straight hole, described projection is inserted in chute and forms and be slidably matched, by projection and the coordinating of chute, chuck is circumferentially fixed on supporter, to prevent that chuck from circumferentially rotating.Thereby the utility model can make the circumferential and axial of chuck all lock reliably.
Accompanying drawing explanation
Fig. 1 is milling cutter clamping device structural representation of the present utility model;
1 is chuck, and 11 is first step hole, and 12 is projection, and 2 is supporter, and 21 is the first straight hole, and 3 is connecting rod, and 31 is push rod.
The specific embodiment
With reference to Fig. 1, a kind of milling cutter clamping device of the present utility model, it comprises chuck 1, supporter 2 and connecting rod 3, chuck 1 is comprised of conical surface section and cylindrical section, chuck 1 is provided with axial first step hole 11, is evenly distributed with a plurality of handle of a knife clip slots in the conical surface section of chuck.Described supporter 2 is provided with second step hole, this second step hole is comprised of the first straight hole 21, the second straight hole and taper hole, the second straight hole is between the first straight hole and taper hole, and the cylindrical section of chuck 1 is spacing by the step surface in second step hole after extending in the second straight hole of supporter.The periphery of the cylindrical section of described chuck 11 is provided with projection 12, in the second straight hole of described supporter, is provided with chute, and when the cylindrical section of chuck extend in the second straight hole, described protruding 12 are inserted into formation in chute is slidably matched.After one end of described connecting rod 3 is passed in the stepped hole on chuck, be threaded with the first straight hole on supporter and pass the outside of the first straight hole, the other end of connecting rod is spacing by the step surface in the first step hole on chuck, and connecting rod is also threaded with the first straight hole.The end that described connecting rod reaches outside the first straight hole is provided with hole, inserts a push rod 31 in this hole.
