Abstract
The utility model relates to a lathe part for metal machining, in particular to a clamping device for a lathe boring cutter. The clamping device for the lathe boring cutter resolves the problems that at present, the change of boring cutter center height caused by axial rotation of the boring cutter in the processes of cutter installation, cutter setting, and boring cutter length adjustment is avoided. The clamping device for the lathe boring cutter comprises a rectangular main body, wherein a cylindrical installing hole which is matched with the boring cutter is formed inside the main body, the installing hole penetrates through two opposite side faces of the main body, the axial direction of the installing hole is parallel to the bottom face of the rectangular main body, a rotation stopping face which is parallel to the axial direction of the installing hole is arranged inside the installing hole, a clamping groove which is parallel to the axial direction of the installing hole is formed inside the main body, and the clamping groove penetrates through the installing hole and one side face of the main body. The clamping device is used for fixing the boring cutter, avoids the fact that the boring cutter rotates in the axial direction, guarantees uniformity of the center height after the boring cutter is replaced and adjusted and before the boring cutter is replaced and adjusted, is simple in operation, saves time of replacement and adjustment of the boring cutter, and improves working efficiency.
Description
Technical field
The utility model relates to a kind of metal processing and uses turned part, is specifically related to a kind of lathe boring cutter clamping device.
Background technology
In the manufacture process of automobile; because the situation that automaker damages through regular meeting's appearance at the various accessories of producing, using in mould and the device procedures; just need change or process maintenance process to damaging accessory and damage the back, in the processing processing procedure, can run into the alternative technique operation of shallow bore hole and deep hole usually.And the handle of a knife of common employed boring cutter is cylindrical at present, columniform handle of a knife has a lot of benefits, for example, can be very convenient in installation process, circular is stressed also more even, but but there is a problem in this columniform handle of a knife in the process of deep hole processing, when when operation is arrived half, in the time of often need adjusting or boring cutter changed the longitudinal separation of boring cutter, the direction of boring cutter remains unchanged before and after but can not guaranteeing to adjust, the change of boring cutter direction may cause the change of centre-height, and this can bring certain adverse effect to production and processing.Therefore how to guarantee that boring cutter can also keep the self-consistentency of direction to be related to precision and the accuracy of processing in length adjustment and replacing process.
The patent disclosure of Granted publication CN 201267943 Y the auxiliary clamp of the general endoporus boring cutter bar of a kind of engine lathe, described auxiliary clamp is the cuboid of profile similar " L " shape, one end clamping platform of cuboid is corresponding with the knife rest clamping structure of engine lathe, the other end clamp body of cuboid vertically is provided with connecting hole, the end face of clamp body is provided with the retaining thread hole, and the retaining thread hole is connected with set bolt.This anchor clamps are fixed by bolt, when installation and tool setting, can not avoid boring cutter to rotate the influence that causes.
The utility model content
The purpose of this utility model is to solve boring cutter on the present lathe in dress cutter, tool setting and adjust the problem that boring cutter centre-height that the axial rotation that can not effectively avoid boring cutter in the process of boring cutter length causes changes, and a kind of lathe boring cutter clamping device is provided.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
A kind of lathe boring cutter clamping device, the main body that comprises a cuboid, be provided with the cylindrical installing hole that matches with boring cutter in the main body, installing hole runs through two relative sides of main body, installing hole axially parallel with the bottom surface of cuboid main body, be provided with a standstill face with the installing hole axially parallel in the installing hole, in main body, be provided with a clamping slot with the installing hole axially parallel, a side of clamping slot penetrating mounting holes and main body.Existing installing hole all is cylindrical hole, in the technical program, by a standstill face is set the boring cutter that inserts installing hole is positioned spline in cylindrical hole, clamping slot forms a space, in use, knife rest clamping structure with lathe is carried out the application of force to clamping slot, and the space of clamping slot is diminished, and has realized main body being fixedly clamped to boring cutter in the insertion installing hole.Installing hole axially and the parallel boring cutter that could guarantee in the bottom surface of cuboid main body move forward and backward the consistent of boring cutter centre-height in the process at installing hole.
As preferred version, installing hole and boring cutter matched in clearance.Matched in clearance is convenient to boring cutter is inserted in the installing hole, reduces the operating distance of clamping slot.
As preferred version, described clamping slot is horizontal direction, and clamping slot and installing hole have the same plane of symmetry.Arranging like this can guarantee that the boring cutter in the installing hole is stressed evenly when the knife rest clamping structure of lathe is carried out the application of force to main body, avoid the boring cutter distortion to take place.
As preferred version, described standstill face is relative with the position of clamping slot.After the standstill face is relative with the position of clamping slot, can make standstill face, installing hole and clamping slot be symmetry shape, thereby when clamping slot was carried out the application of force, assurance was even to the boring cutter application of force.
As preferred version, the height of described standstill face is less than the diameter of installing hole.The height of standstill face can guarantee that less than the diameter of installing hole installing hole is enough big, avoids the reduction of the boring cutter intensity that matches with installing hole.
As preferred version, the hole wall arc-shaped transition of described standstill face and installing hole.Arc-shaped transition can avoid stress to concentrate, and increases the intensity of installing hole.
Owing to adopt technique scheme, the beneficial effects of the utility model are: boring cutter is fixed in the axial direction, effectively avoided boring cutter rotation in the axial direction, and then guaranteed the consistent of centre-height in the front and back of changing boring cutter and adjustment boring cutter length, also can effectively fix boring cutter simultaneously, prevent boring cutter shake at work, saved the time that boring cutter is changed and adjusted, improved operating efficiency.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Among the figure: 1 main body, 2 installing holes, 3 standstill faces, 4 clamping slots.
The specific embodiment
