Detailed Description
The invention is further described with reference to the following figures and detailed description.
As shown in fig. 1 to 4, the repairable thread machining tool includes a tool bar 1, a cutting bar 2, and a fixing structure 3; the cutter bar 1 is horizontally arranged, the front part of the cutter bar 1 is provided with a cutting strip hole 11, the cutting strip hole 11 extends from the top surface of the cutter bar 1 to the rear and lower direction, and the front side wall surface of the cutting strip hole 11 is a V-shaped positioning surface 14; the cutting strip 2 is inserted into the cutting strip hole 11, the front surface of the cutting strip 2 is provided with two rear tool surfaces 21, the top surface of the cutting strip 2 is provided with a front tool surface 22, the intersection line of the rear tool surface 21 and the front tool surface 22 is a cutting edge 23, the included angle of the two rear tool surfaces 21 is matched with the thread form angle, the upper part of the cutting strip 2 is exposed out of the cutter bar 1, and the cutting edge 23 exceeds the front end of the cutter bar 1; the fixing structure 3 is arranged on the cutter bar 1 and presses the cutting strip 2 forwards, so that the rear cutter face 21 is tightly abutted to the V-shaped positioning face 14; when the fastening structure 3 is released, the cutter bar 2 can move along the cutter bar hole 11.
When the cutting edge 23 is worn or broken, the fixing structure 3 is loosened, the position of the cutting strip 2 is adjusted to increase the extending length of the cutting strip or the cutting strip 2 is detached, and the cutting strip 2 is ground and repaired. Because the front surface of cutting strip 2 is two flank faces 21, and the contained angle of two flank faces 21 matches with the screw thread profile angle, during the grinding, need not grind flank face 21, also need not grind out the profile angle, only need grind the top surface of cutting strip 2 and grind out cutting edge 23 and rake face 22 again. Compared with the prior art, the grinding method is obviously simpler and more convenient, has low technical requirement on a grinder, and can save grinding time. The high-grindable thread machining tool is beneficial to being widely applied.
The different thread profile angles are different, for example, 60 ° for a metric triangular thread, 30 ° for a metric trapezoidal thread, 29 ° for an acme female trapezoidal thread, 55 ° for an english hui triangular thread, and the included angle of the two flank surfaces 21 of the cutting strip 2 can be designed to be different depending on the thread to be cut.
The fixing structure 3 can be a compression screw which is perpendicular to the cutting strip 2 and is in threaded connection with the cutter bar 1, and the compression screw is screwed down to compress the cutting strip 2 so as to fix the cutting strip 2.
The above-mentioned method relies on the frictional force to prevent the cutting strip 2 from moving down, and the reliability is relatively poor. A pressing block cavity 12 is formed in a preferable cutter bar 1, the pressing block cavity 12 is located behind a cutting strip hole 11, and the rear wall surface of the pressing block cavity 12 is a vertical positioning surface 13; the rear side of the cutting strip 2 is provided with a plurality of cutting strip teeth 24 which are continuously arranged along the length direction of the cutting strip 2, and the cutting strip teeth 24 are provided with a horizontally arranged cutting strip tooth top surface 25 and a vertically arranged cutting strip tooth side surface 26; the fixing structure 3 comprises a pressing block 31 and a locking screw 32; the shape of the pressing block 31 is wedge-shaped, the pressing block 31 is positioned in the pressing block cavity 12 and can move up and down, a plurality of pressing block teeth 311 are arranged on the front side of the pressing block 31, and each pressing block tooth 311 is provided with a horizontally arranged pressing block tooth bottom surface 312 and a vertically arranged pressing block tooth side surface 313; the locking screw 32 is vertically arranged, the locking screw 32 is connected with the cutter bar 1 and tightly supports the pressing block 31 downwards, the rear side face of the pressing block 31 tightly supports the vertical positioning face 13, the pressing block teeth 311 are meshed with the cutting rack teeth 24, the pressing block tooth bottom face 312 tightly supports the cutting rack teeth top face 25, and the pressing block tooth side face 313 tightly supports the cutting rack teeth side face 26.
When the cutting strip 2 works, the cutting strip 2 can only move backwards and downwards along the cutting strip hole 11 under the action of a downward force given by a workpiece due to the action of the cutting strip hole 11; however, since the tooth side 313 of the pressing block abuts against the tooth side 26 of the cutting strip and the rear side of the pressing block 31 abuts against the vertical positioning surface 13, the cutting strip 2 cannot move backward, i.e., cannot move backward and downward. The fixing structure 3 limits the movement of the cutting strip 2 by the surface-to-surface abutting, and has high reliability.
When the cutting strip 2 needs to be ground, the locking screw 32 is loosened, the pressing block 31 moves upwards, the cutting strip teeth 24 are separated from the pressing block teeth 311, and the cutting strip 2 can be moved and taken out. If the cutting strip 2 is detached, after grinding is completed, the cutting strip 2 is inserted into the cutting strip hole 11, and the locking screw 32 is tightened again to enable the pressing block 31 to press the cutting strip 2 again.
As shown in fig. 3, a thin rod can be used to extend into the cavity 12 from below the tool holder 1 and press the pressing block 31 upward to move it upward, but this is cumbersome. To facilitate the lifting of the holding-down block 31. As shown in fig. 3, the thread machining tool preferably includes a top screw 4, and the top screw 4 is connected to the shank 1 and can be pressed against the pressing block 31. The upper jacking screw 4 can be rotated to jack the pressing block 31. When the cutting strip 2 is installed back, the upper jacking screw 4 is retracted.
In order to prevent the pressing block 31 from moving left and right and swinging, left and right side surfaces of the pressing block 31 preferably abut against left and right wall surfaces of the pressing block cavity 12.
Further, in order to limit the pressing block 31 to move only up and down, as shown in fig. 4, it is preferable that the locking screw 32 has a guide post 321, the pressing block 31 has a guide hole 314, and the guide post 321 is inserted into the guide hole 314 and engaged with the guide hole 314. The guide post 321 and the guide hole 314 should be a loose fit and have a loose fit.
The flank surface 21 abuts against the V-shaped positioning surface 14 to prevent the cutting strip 2 from moving left and right and swinging, and in order to further improve the positioning effect, it is preferable that the cutting strip 2 has two cutting strip side surfaces 28 located behind the flank surface 21, the wall surface of the cutting strip hole 11 includes two hole side wall surfaces 15 located behind the V-shaped positioning surface 14, and the cutting strip side surfaces 28 are attached to the hole side wall surfaces 15. This improves the positioning effect and prevents chips from entering the chip pocket 11.
If the cutting strip 2 is vertically arranged, the cutting edge 23 cannot exceed the front end of the cutter bar 1, so that cutting is difficult to realize, and the angle of the flank surface 21 does not meet the requirement. If the cutting strip 2 is horizontally arranged, it cannot be conveniently ground. The cutting chip 2 of the present invention is thus disposed obliquely, which requires the cutting chip hole 11 to extend downward from the top surface of the holder 1. In general, the angle between the axis of the cutter bar hole 11 and the axis of the cutter bar 1 is preferably 60 °.
The length of the cutting strip 2 exposed out of the upper surface of the cutter bar 1 is proper, if the length is too short, the length of the cutting edge 23 is not enough, and if the length is too long, the stability of the cutter is poor. In order to facilitate the control of the length of the cutting strip 2 exposed from the upper surface of the holder 1, it is preferable that the cutting strip 2 has a position mark scale 27 on the side surface thereof along the length direction of the cutting strip 2. The length of the cutting strip 2 exposed out of the upper surface of the cutter bar 1 can be controlled by observing the position mark scale 27 of the cutter bar 1 and controlling the insertion depth of the cutting strip 2.
The tool holder 1 and the holding-down block 31 of the invention can be made of the materials of conventional tool holders. The cutting bar 2 may be made of high speed steel or cemented carbide.
