Abstract
The utility model discloses a saw blade milling cutter handle, relating to the field of machining cutters and providing a saw blade milling cutter handle in which all fixed components of the installed saw blade milling cutter are slightly higher than the outer side surfaces of the saw blade milling cutter. The saw blade milling cutter handle comprises a cutter handle main body, a mandril and a fixed part, wherein the mandril consists of a positioning part and a compression part, a through hole is axially formed in the mandril along with the mandril, and a key slot A is formed in the positioning part; a positioning hole is formed in the cutter handle main body along with the axial direction of the cutter handle main body, and a key slot B is formed in the surface of the positioning hole; the positioning part is inserted into the positioning hole and is in clearance fit with the positioning hole, and the key slot A and the key slot B correspond to each other in position; the fixed part penetrates through the through hole and is in threaded connection with the cutter handle main body, and the mandril is connected with the cutter handle main body through the fixed part; the position between the end surface of the cutter handle main body and the compression part is a milling cutter fixing position. The saw blade milling cutter is fixed by the saw blade milling cutter handle and then used for machining slots in positions with narrow space.
Description
Technical field
The utility model relates to machine tool field, relates in particular to a kind of metal saw handle of a knife.
Background technology
In the time that workpiece is carried out to groove milling, conventional metal saw.Existing metal saw fixed form is as follows: on metal saw handle of a knife, be provided with mandrel, metal saw is sleeved on mandrel, metal saw thickness is fixed and be greater than to mandrel length, can be at metal saw both sides pad pad in order to compress metal saw, pad and metal saw thickness sum are slightly larger than mandrel length and could metal saw be pressed on metal saw handle of a knife with bolt.
Aforesaid way shortcoming is: if the first pad pad is in metal saw outside (outside is away from a side of handle of a knife and lathe connecting portion), it is more that pad, mandrel and set bolt exceed metal saw outer surface, when part to be processed working position space is very narrow and small, pad, mandrel and set bolt easily and part to be processed interfere.The second, compressing multiple pads by nut and lock saw blade, can there is many systematic errors in such structure, as thread center's out of plumb, pad out-of-flatness, while finally causing saw blade to be installed, is not that face contacts with face, and out-of-flatness is installed, and when use, rigidity is bad; In metal saw inner side, there is this problem in (inner side is near a side of handle of a knife and lathe connecting portion) and outside to pad pad.Three, metal saw being installed at every turn need to pad, and it is more inconvenient to operate.
Utility model content
The technical problems to be solved in the utility model is: provide a kind of metal saw is installed after the each fixed part of metal saw exceed the less metal saw handle of a knife of metal saw outer surface.
For the technical scheme that addresses the above problem employing is: metal saw handle of a knife comprises holder main body, mandrel and fixture, mandrel comprises location division and compressed part, in mandrel, is axially provided with through hole along mandrel, is provided with keyway A on location division; In holder main body, be axially provided with locating hole along holder main body, locating hole surface is provided with keyway B; Location division insert locating hole and with locating hole matched in clearance, keyway A and keyway B position correspondence; Fixture passes through hole and is threaded with holder main body, and mandrel is connected with holder main body by fixture; Position between end face and the compressed part of holder main body is milling cutter fixed position.
Further: fixture end face is not higher than end face of mandrel.
The beneficial effects of the utility model are: the first, metal saw is sleeved on mandrel, and mandrel restriction metal saw moves radially; Key is arranged in keyway A and keyway B for carry-over moment; Compressed part is pressed in metal saw the end face of holder main body, and restriction metal saw moves axially.The amount that mandrel exceeds metal saw outside is only compressed part thickness, reduces compressed part thickness as far as possible and can at utmost reduce mandrel and exceed the amount in metal saw outside in the situation that of proof strength, is beneficial to the groove of the narrow and small position of metal saw processing space.Further make fixture end face can further not reduce handle of a knife and exceed the amount in metal saw outside higher than end face of mandrel.
The second, location division and locating hole matched in clearance, processing ensures the perpendicularity of compressed part and location division, can ensure that compressed part and metal saw are that face contacts with face, install smooth, good rigidly when use.
Three, do not need pad, it is convenient that metal saw handle of a knife is installed.
Brief description of the drawings
Fig. 1 is structure chart after metal saw handle of a knife installation metal saw;
In figure, be labeled as: holder main body 1, locating hole 2, mandrel 3, keyway B4, key 5, keyway A6, fixture 7, compressed part 8, metal saw 9, location division 10, through hole 11.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is further illustrated.
Metal saw handle of a knife comprises holder main body 1, mandrel 3 and fixture 7, and mandrel 3 comprises location division 10 and compressed part 8, and mandrel 3 is interior is axially provided with through hole 11 along mandrel 3, is provided with keyway A6 on location division 10; Holder main body 1 is interior is axially provided with locating hole 2 along holder main body 1, and locating hole 2 surfaces are provided with keyway B4; Location division 10 insert locating hole 2 and with locating hole 2 matched in clearance, keyway A6 and keyway B4 position correspondence; Fixture 7 passes through hole 11 and is threaded with holder main body 1, and mandrel 3 is connected with holder main body 1 by fixture 7; Position between the end face of holder main body 1 and compressed part 8 is milling cutter fixed position.When use, metal saw 9 is sleeved on mandrel 3, and mandrel 3 limits metal saw 9 and moves radially; Key 5 is arranged in keyway A6 and keyway B4 for carry-over moment; Compressed part 8 is pressed in metal saw 9 end face of holder main body 1, and restriction metal saw 9 moves axially.Add and need ensure compressed part 8 and perpendicularity metal saw 9 contact-making surfaces and location division 10 man-hour.Most of metal saw 9 is useful on the keyway of transmitting torque, and a small amount of metal saw 9 does not have.The utility model is installed while thering is no the metal saw 9 of keyway not fitting key 5.
Exceed the amount in metal saw 9 outsides in order to reduce to greatest extent handle of a knife, should make fixture 7 end faces not higher than mandrel 3 end faces.Concrete, it is hexagon socket cap head screw that fixture 7 is recommended to make, and the hole that socket cap is held in processing on mandrel 3 can make fixture 7 end faces not higher than mandrel 3 end faces.
