Abstract
The invention discloses a switching tool shank which comprises a tool shank body, wherein the front half part of the tool shank body is a cylinder; the surface of the cylinder is threaded and matched with a nut; a taper hole is arranged at the front end of the cylinder; a through hole is formed along the radial direction on the cylinder and is communicated with the taper hole; a broach screw is arranged in the taper hole; the back end of the broach screw is fixedly connected with a broach plate; and the broach plate is inserted into the through hole and resists on the back end surface of the nut. The switching tool shank of the invention needs not to be pulled out from a main shaft, a tool can be conveniently detached only by loosening the nut, and a new tool can be used only by screwing the nut tightly. Because the actions of inserting and pulling the tool shank are avoided, the efficiency is higher, and simultaneously, because the times that the tool shank is inserted and pulled in the main shaft are greatly reduced, the abrasion of the main shaft of a machine tool is also effectively reduced.
Description
Technical field
The present invention relates to a kind of machine tool component, be specifically related to a kind of switching tool shank that on lathe, is used for mounting cutter.
Background technology
Present 7: 24 common switching tool shanks, handle of a knife need be extracted from main shaft when changing the outfit cutter, twist the blind rivet of handle of a knife afterbody, unscrew the soket head cap screw that places handle of a knife inside, new cutter is installed then, tighten soket head cap screw and afterbody blind rivet successively, again the handle of a knife that installs cutter is inserted in the main shaft.Whole process need is unscrewed and is screwed two place's screw threads again, and each will be extracted, be turned back to handle of a knife once from main shaft.
Like this, when changing cutter, not only dismounting efficient is low, and plugs the wearing and tearing that also can cause machine tool chief axis continually.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of switching tool shank that can improve cutter mounting or dismounting efficient, to overcome the above-mentioned defective of prior art.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme: a kind of switching tool shank, comprise a handle of a knife body, the first half of handle of a knife body is a cylinder, described cylindrical surface is provided with screw thread and matches with a nut, cylindrical front end is provided with taper hole, radially have a through hole on the cylinder and be connected with described taper hole, be provided with a broaching tool screw in the described taper hole, fixedly connected with a broaching tool plate in the rear end of broaching tool screw, the broaching tool plate is inserted in the described through hole and is against on the rear end face of nut.
Preferably, described cylindrical front end also is provided with key.
Preferably, described key is integrally formed on the cylindrical front end face.
Preferably, the latter half of described handle of a knife body is a taper shank, and the rear end of taper shank is connected with blind rivet.
The invention has the beneficial effects as follows: need not from main shaft, to extract switching tool shank, can pull down cutter easily as long as unclamp nut, change new cutter after, again nut screwing clamping is got final product.Owing to avoided the action of handle of a knife plug, thereby efficient is higher; Simultaneously, owing to significantly reduced the number of times that handle of a knife plugs in main shaft, the wearing and tearing of machine tool chief axis have also been reduced effectively.
Description of drawings
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail.
Fig. 1 is the structural representation of switching tool shank of the present invention.
The specific embodiment
As shown in Figure 1, switching tool shank of the present invention comprises handle of a knife body 1, and the first half of handle of a knife body 1 is a cylinder 5, and latter half is a taper shank 10, can match with the endoporus of machine tool chief axis.The rear end of taper shank 10 is connected with blind rivet 4, and blind rivet 4 designs by relevant criterion according to the main shaft type.
The surface of cylinder 5 is provided with screw thread and matches with a nut 3, and the front end of cylinder 5 is provided with taper hole 7, can match with the taper shank of cutter.Radially have a through hole 9 on the cylinder 5, through hole 9 is connected with taper hole 7, is provided with a broaching tool screw 8 in the taper hole 7, fixedly connected with a broaching tool plate 2 in the rear end of broaching tool screw 8, broaching tool plate 2 is inserted in the through hole 9, and expose from through hole 9 at the two ends of broaching tool plate 2, and can be resisted against on the rear end face of nut 3.The size of through hole 9 should guarantee that broaching tool plate 2 can put in easily together with broaching tool screw 8.
The front end of cylinder 5 is provided with two keys 6 that protrude forward, and key 6 is used for transmitting moment of torsion between switching tool shank and cutter.In the present embodiment, two keys 6 and handle of a knife body have been made one, and they are integrally formed on the front end face of cylinder 5.Certainly, also can adopt two independent general flat keys to be installed on the handle of a knife body, but better with the bond strength of handle of a knife body one.
Using method to switching tool shank of the present invention is described further below.
Switching tool shank of the present invention is connected on the machine tool chief axis by taper shank 10, during mounting cutter, in advance nut 3 be contained in cylinder 5 than front end, away from through hole 9.The broaching tool plate 2 that has broaching tool screw 8 is injected in the through hole 9, and lean against the foremost of through hole 9, make broaching tool screw 8 be positioned at taper hole 7.Then cutter is filled in the taper hole 7, rotary cutter makes the screw of cutter rear end and broaching tool screw 8 by being threaded togather, when cutter will contact with key 6, adjust the angle of cutter, make keyway on the cutter and key 6 over against, rotating nut 3 then, nut 3 promotes broaching tool plate 2 and cutter slides backward together, cutter and taper hole 7 are closely cooperated, with and guarantee certain pretightning force, simultaneously, key 6 also embeds in the keyway on the cutter, has so just finished the installation of cutter.
, also need not switching tool shank is pulled up from machine tool chief axis during cutter in dismounting,, cutter is extracted a segment length outward, throw off with key 6 as long as unclamp nut 3, then can rotary cutter, make it to break away from and get final product with broaching tool screw 8.
The present invention can be used for the cutter that has 7: 24 taper shanks is installed, and is particularly suitable for using the occasion that many handles have the cutter of same size taper shank instead.
