Description
Technical Field
The invention relates to cutting machining, in particular to a method for adjusting a cutting tool blade.
Background
In metal working, the higher the precision of the cutting tool, the better, but the unlimited pursuit of precision will increase the cost significantly. Moreover, since the cutting tool is composed of the tool body and the cutting insert, the precision of the fit between the two and the precision of the fit between the cutting tool and the machine tool will affect the final use precision. Therefore, in the case of a high precision requirement, it is currently common practice to design a special adjusting mechanism on the tool body, and to adjust the position of the blade in the tool body to meet the precision requirement. However, this type of adjustment mechanism requires the cooperation of an instrument capable of indicating the precision, namely: the adjusting mechanism can only accurately adjust the position of the tool nose, and cannot judge whether the height of the tool nose reaches the accurate position, so that the adjusting mechanism usually needs a mechanism capable of indicating the position, such as a tool setting gauge or a jump meter, to be matched for use. Moreover, these adjustments are typically made outside of the machine tool. When the adjusted cutting tool is mounted on a machine tool, it is also affected by the accuracy of the fit of the machine tool with the tool.
Fig. 1 shows a cutting tool commonly used in the prior art. The cutter is a revolving body taking a central line shaft C as a revolving center, blades 2 are distributed on a cutter disc 1 of the cutter along the circumferential direction, and the blades 2 are fixed through a compression wedge block 3 and a double-headed screw 61. When the cutting tool of the type is used for machining, the higher the consistency of the distance H between the end surface of the cutter disc 1 far away from the cutter blade and the cutter point of the cutter blade 2 is, the better the machined surface quality is.
Fig. 2 shows an exploded view of the cutting tool of fig. 1. The pressing wedge 3 is installed in the first threaded hole 51 of the pressing groove 5 by the stud screw 61, and the pressing wedge 3 can move back and forth along the axis of the first threaded hole 51 with the rotation of the stud screw 61, thereby completing the pressing and releasing of the blade 2. The cutter head 1 is provided with a cutter groove 4, and the cutter groove 4 is provided with a cutter groove side surface I41, a cutter groove side surface II 42 and a cutter groove bottom surface 43. The insert 2 is mounted in the pocket 4 with three surfaces on the insert 2 abutting the pocket side surface one 41, the pocket side surface two 42 and the pocket bottom surface 43, respectively, thereby achieving accurate positioning of the cutting insert on the cutting tool. The cutting tool is widely used in machining due to its simple structure. But has the disadvantages that: as shown in fig. 1, in order to improve the machining precision, the requirement is that the distance H between the end surface of the cutter head 1 and the cutter tip is better to be consistent, in the scheme, the blade 2 is positioned through the cutter groove side surface one 41 opposite to the cutter tip, and when the sizes of the blades 2 are different, the distance H is changed, so that the actual precision is influenced.
In order to solve the problem, the prior art has a solution that the first sipe side surface 41 is designed on an adjustable mechanism, and the blade 2 is moved by adjusting the position of the first sipe side surface 41, so that the consistency of the distance H is improved. The disadvantage of this solution is that it needs an instrument that can display the size of the position of the nose of the cutting blade 2 to be matched for convenient adjustment, and the tool needs to be installed on a machine tool after being adjusted for use, and the matching precision of the cutting tool and the machine tool also affects the final use precision.

s1, placing a positioning piece in the knife groove 4: before the blade 2 is installed, a positioning piece 7 is placed in the knife groove 4, and the positioning piece 7 abuts against a knife groove side face I41 of the knife groove 4 towards the adjusting direction of the blade 2;
s2, mounting a first blade: installing the first blade 2 in the cutter groove 4 and abutting against the positioning piece 7, installing the corresponding pressing wedge block 3 and the corresponding fastening piece 6 at the same time, and adjusting the fastening piece 6 to pre-press the first blade 2;
s3, taking out the positioning piece: after the first blade 2 is pre-compressed, the positioning piece 7 is taken out, and an adjusting gap L1 is generated between the first blade 2 and the first cutter groove side surface 41;
s4, installing the rest blades: according to the mounting step S1 and the step S2, the positioning piece 7 is adopted to continue to mount the second blade 2, after the second blade 2 is pre-pressed, the positioning piece 7 is taken out again, an adjusting gap L1 is generated between the second blade 2 and the first blade groove side surface 41, the steps S1 and the step S2 are repeated until the positioning piece 7 is taken out after the last blade 2 is pre-pressed, and an adjusting gap L1 is generated between the last blade 2 and the first blade groove side surface 41;
s5, aligning the tool nose by adopting the test workpiece 8: installing a cutter head 1 on a main shaft of a machine tool, installing a test workpiece 8 on the machine tool, moving the test workpiece 8 to enable the test workpiece 8 to be in contact with one of the blades 2, slowly rotating the cutter head 1, when the cutter point of the blade 2 protrudes out of the test workpiece 8, the cutter head 1 rotates to push the blade 2 to enable the blade 2 to overcome the pre-pressing force to move towards an adjusting gap L1 so that the cutter point of the blade 2 is in contact with the test workpiece 8, and continuing to rotate the cutter head 1 until the cutter points of all the blades 2 sequentially contact the test workpiece 8, wherein the cutter points of all the blades 2 are positioned on the same circle;
s6, adjusting the fasteners 6 to fully compress the compression wedges 3 against the blade 2.
In this embodiment, in step S5, the direction of rotation of the cutter head 1 is indicated by a counterclockwise arrow in fig. 8 (hereinafter, referred to as "reverse rotation"), and this reverse rotation is opposite to the direction of rotation during normal cutting operation of the cutter. So that the test workpiece 8 is cut off without first touching the tip of the insert 2 during rotation. The axis of rotation of the cutter head 1 is C.
Steps S2 to S4 are performed by positioning the blades 2 in the knife slot 4 by using a positioning member 7, so that after the positioning member 7 is taken out, an adjusting gap L1 is generated between all the blades 2 and the knife slot side surface one 41 of the knife slot 4, and the adjusting gaps L1 of the blades are consistent.
In step S5, since the cutting edge P of the blade 2 has the flank 21 (a surface that makes the cutting edge have a clearance angle, and usually the clearance angle is an acute angle), when the cutting edge P protrudes out of the test workpiece 8 in the process of reversing the cutter head 1, the flank 21 of the blade 2 first contacts the end surface of the test workpiece 8, and the flank 21 and the test workpiece 8 generate pushing force along with the rotation of the cutter head 1, and since the blade 2 is in the pre-compression stage, the test workpiece 8 can push the blade 2 to move toward the first sipe side 41, that is, move in the adjustment gap L1, until the cutting edge P passes through the end surface of the test workpiece 8, so that the position of the blade 2 can be adjusted, and as a result of the adjustment, the distance from the cutting edge to the end surface of the test workpiece 8 is 0. When all the tool tips are adjusted through the end surface of the test workpiece 8, the height difference of the tool tips P of all the cutting blades 2 in the axial direction of the cutter head 1 is 0, that is, the tool tips P of all the cutting blades 2 are positioned on the same circle, so that the adjustment of the precision of the tool tips of the cutting blades is realized. Finally, the full compression in step S6 provides sufficient pressure to avoid movement of the blade 2 during cutting. When the test workpiece 8 is moved, all the blades 2 are guaranteed to protrude out of the end face of the test workpiece 8 before being adjusted, and therefore all the tool tips are guaranteed to uniformly contact the end face of the test workpiece 8.
The adjusting method of the cutter blade is essentially characterized in that the precision adjustment is completed by utilizing the same point or pushing of the blade 2, and in the adjusting process, the blade 2 is not completely locked and can move under the action of external force without an additional adjusting mechanism. Specifically, when the blades are installed, the blades 2 in the cutter groove 4 are positioned by the positioning piece 7, so that after the positioning piece 7 is taken out, an adjusting gap L1 is formed between all the blades 2 and the cutter groove side surface 41 of the cutter groove 4, the adjusting gaps L1 of all the blades are consistent, when the blades are in contact with a test workpiece, the reverse cutter head 1 can enable the blades protruding out of the test workpiece to move towards the cutter groove 4 in the adjusting gap L1, the height difference of the cutter point P in the axial direction of the cutter head 1 is 0, the regularity of all the cutter points on the same circle is ensured, the installation errors of the blades are reduced, the position consistency of the blades 2 is high, the cutting precision of the cutter is improved, and the cutting effect is improved. Because the cutting tool is installed on the machine tool spindle for precision adjustment, errors caused by matching of the cutting tool and the machine tool spindle are avoided.

The pre-compression in steps S2 to S5 is elastic compression, and in this compressed state, the compression wedge 3 applies a certain pressure to the blade 2, and the blade 2 can move in the knife groove 4 under the action of a certain external force. In the step S6, the complete compression is rigid compression, the elastic compression of the pressing wedge 3 on the blade 2 is converted into rigid compression, the pressure is increased, the blade 2 reaches a locked state, and the blade 2 cannot move in the knife groove 4 under a certain external force.
In this embodiment, the distance h between two opposite surfaces of the cutting seam 31 is 2-3 mm. The compression wedge 3 is of a wedge-shaped construction, preferably of high-strength steel. When the pressing wedge 3 is pressed, the suspending portion 311 can be bent inward of the pressing wedge 3 to be elastically deformed.

In this embodiment, the test workpiece 8 is a cylinder, and the tip P of the blade 2 is in contact with one end surface of the cylinder.
In this embodiment, fastener 6 is stud 61, is equipped with screw hole one 501 in the pressure tank 5, is equipped with screw hole two 301 on the pressure wedge 3, and stud 61 all cooperates with screw hole one 501 and screw hole two 301 screw thread.
