Example 1
Referring to fig. 1, the present embodiment provides a cutter body mounting seat, which is provided with an integral cutter body mounting portion and a fixing portion;
the cutter body mounting part is used for mounting the cutter body 10; the feeding direction of the cutter body 10 is a first direction, and the head of the cutter body 10 extends out of the cutter body mounting part;
The fixing part is positioned at one side of the cutter body mounting part and is used for fixing the cutter body mounting seat on a machine tool;
The fixing part is provided with an adjusting groove, and the adjusting groove is provided with a first side wall and a second side wall which are oppositely arranged; the arrangement direction from the first side wall to the second side wall is parallel to the first direction;
the fixing part is provided with a first gap 21 and a second gap 22, and the first gap 21 extends from the first side wall to a direction away from the head of the cutter body 10; the second slit 22 extends from the second side wall in a direction approaching the head of the cutter body 10;
The driving device 3 is fixedly arranged on the first side wall, and the driving device 3 is fixed on the first side wall and is positioned at one side of the first gap 21 away from the cutter body mounting part; the driving device 3 is configured to provide thrust to the second side wall, and the stress portion of the second side wall is located at a side of the second gap 22 near the cutter body mounting portion.
Since the driving device 3 is fixed on the side of the first gap 21 away from the cutter body mounting portion, the output end of the driving device 3 acts on the side of the second gap 22 on the second side wall, which is close to the cutter body mounting portion, and the first gap 21 and the second gap 22 form a thin-wall structure on the side of the fixing portion away from the adjusting groove. When the driving device acts, the first gap 21 and the second gap 22 are taken as boundaries, a part of the fixing portion, which is close to one side of the machine tool, is fixed on the machine tool, so that large deformation cannot be generated, a part of the fixing portion, which is far away from one side of the machine tool, is subjected to the thrust of the driving device 3, so that large deformation can be generated at the end parts of the first gap 21 and the second gap 22, and then the part of the fixing portion, which is far away from one side of the machine tool, moves along the first direction, and then drives the cutter body mounting portion to move along the first direction, and finally drives the cutter body 10 to move along the first direction. The above process can quickly realize the adjustment of the position of the cutter body 10 without detaching and then installing the cutter body 10.
In a preferred embodiment of the end construction of the first slit 21 and the second slit 22, the end of the first slit 21 forms a first deformation hole 210, the end of the second slit 22 forms a second deformation hole 220, and the first deformation hole 210 and the second deformation hole 220 are used for forming the fixing part into a thin-wall structure on the side far from the adjusting groove.
The first deformation hole 210 is arranged at the end part of the first gap 21, and the second deformation hole 220 is arranged at the end part of the second gap 22, so that the thin-wall structure formed at the side far away from the adjusting groove of the fixing part can be further thinned; on the other hand, the end portions of the first slit 21 and the second slit 22 can be deformed to a larger extent, and finally, the position of the cutter body 10 can be adjusted to a larger extent.
In a preferred embodiment of the first deformation hole 210 and the second deformation hole 220, a third slit 23 is disposed in the first deformation hole 210, and the third slit 23 extends to a side far from the cutter body mounting portion; a fourth slit 24 is provided in the second deformation hole 220, and the fourth slit 24 extends to a side close to the cutter body mounting portion.
The third gap 23 is communicated with the first deformation hole 210, the fourth gap 24 is communicated with the second deformation hole 220, the first gap 21 and the second gap 22 are used as boundaries, when a part of the fixing part, which is far away from one side of the machine tool, moves towards the first direction, large deformation occurs in the first deformation hole 210 and the second deformation hole 220, the deformation is conducted into the third gap 23 and the fourth gap 24, but the deformation is also controlled in the third gap 23 and the fourth gap 24, so that the cutter body mounting seat is not damaged due to metal fatigue caused by overlarge deformation.
Wherein in a preferred embodiment of the construction of the third slit 23 and the fourth slit 24, a third deformation hole 230 is provided at an end of the third slit 23 remote from the first deformation hole 210; the end of the fourth slit 24 far away from the second deformation hole 220 is provided with a fourth deformation hole 240, and the third deformation hole 230 and the fourth deformation hole 240 are used for forming a thin-wall structure on the side of the fixing portion far away from the adjusting groove.
The third deformation hole 230 is disposed at an end of the third slit 23 away from the first deformation hole 210; the fourth deformation hole 240 is formed in the fourth slit 24 at the end far away from the second deformation hole 220, so that the deformation range of the fixing portion located at two sides of the adjusting groove is larger, deformation is easier to occur on one hand, damage possibly caused by smaller deformation range is overcome when deformation occurs, and the service life of the cutter body mounting seat is prolonged.
In a preferred embodiment of the third slit 23 and the fourth slit 24, the third slit 23 extends parallel to the fourth slit 24.
As described above, when the portion of the fixed portion away from the machine tool side moves in the first direction, the first deformation hole 210 and the second deformation hole 220 are greatly deformed, and the deformation is conducted into the third gap 23 and the fourth gap 24, but the deformation is also controlled in the third gap 23 and the fourth gap 24, and the third gap 23 and the fourth gap 24 synchronously limit the movable range of the cutter body 10 along the first direction because the extending direction of the third gap 23 is parallel to the extending direction of the fourth gap 24. This ensures that sufficient adjustable space is provided for the blade body 10; but also can ensure that the cutter body mounting seat does not generate metal fatigue due to overlarge deformation.
In a preferred embodiment of the first slit 21 and the second slit 22, the first slit 21 extends parallel to the second slit 22.
In combination with the foregoing, since the extending direction of the third slit 23 is parallel to the extending direction of the fourth slit 24, and the extending direction of the first slit 21 and the extending direction of the second slit 22 are set to be parallel, at this time, the connecting lines of the centers of the first deformation hole 210, the third deformation hole 230, the second deformation hole 220 and the fourth deformation hole 240 are in a parallelogram shape, so that when the part of the fixing portion away from the machine tool side moves to the first direction, the internal deformation degrees of the first deformation hole 210 and the second deformation hole 220 are consistent; the third deformation hole 230 is consistent with the deformation degree inside the fourth deformation hole 240, so that the deformation provided by the portions on two sides of the adjusting groove on the fixing portion is consistent, and one side with larger deformation due to asymmetry of deformation is not damaged.
In a preferred embodiment of the shapes of the first deformation hole 210, the second deformation hole 220, the third deformation hole 230 and the fourth deformation hole 240, the first deformation hole 210, the second deformation hole 220, the third deformation hole 230 and the fourth deformation hole 240 are cylindrical holes.
The shapes of the first deformation hole 210, the second deformation hole 220, the third deformation hole 230 and the fourth deformation hole 240 are all cylindrical, each point on the inner wall deforms when the inside of the cutter body is deformed, and each point is in a bearing force, so that the forces in the deformation holes are relatively even, and meanwhile, after the cutter body mounting seat completes the position adjustment of the cutter body 10, a better resilience force can be provided for the cutter body mounting part.
Preferably, the axes of the first deformation holes 210, the second deformation holes 220, the third deformation holes 230, and the fourth deformation holes 240 are perpendicular to the first direction. In this way, in the direction perpendicular to the first direction, the forces of the points in the first deformation hole 210, the second deformation hole 220, the third deformation hole 230 and the fourth deformation hole 240 are consistent, and the deformation of the first deformation hole 210, the second deformation hole 220, the third deformation hole 230 and the fourth deformation hole 240 along the respective axial directions are synchronous.
Wherein in a preferred embodiment of the driving device 3, the driving device 3 is a gas-liquid booster cylinder.
Because of the characteristics of the gas-liquid pressurizing cylinder, the speed is slower when the gas-liquid pressurizing cylinder acts, and slight adjustment can be realized under the condition of not adding a speed reducer, so that the cutter body mounting seat is not deformed and damaged due to overlarge action.
