Problems solved by technology

[0002] Lathes (including ordinary lathes and CNC lathes) require that the tool tip of the tool must be at the center height of the rotating part during processing, otherwise the actual rake angle and rear angle of the tool cutting will be changed because the tool is not at the center height, or the part will be cut during cutting. Can not be cut off, and very easy to cause a knife
After the traditional tool is manufactured, the center height of the tool is fixed. For welded turning tools, when the tool is sharpened, especially after the rake face is sharpened, the actual center height of the installed tool will become lower.
The traditional method is to use some gaskets with different thicknesses for installation and adjustment. This method is time-consuming and laborious to adjust the center height; moreover, the flatness of the gaskets is not good after repeated use, especially after the combination of multiple gaskets. The phenomenon of unreliable installation will occur when tightening the pressure knife screw

Embodiment 1

[0039] Such as figure 1 As shown, it is a structure of the turning tool of the present invention. The bottom of the tool body 1 is provided with a groove inward along its length direction. The groove has two symmetrical slopes that gradually retract from the outside to the inside, that is, the radial direction of the tool body The groove on the cross section is in the shape of an isosceles trapezoid, and the groove is larger near the outer opening of the cutter body and smaller near the inner opening of the cutter body, such as figure 2 . There are multiple rows of protruding short cylinders evenly arranged on the two slopes, and the connection line of each row of short cylinders is parallel to the length direction of the cutter body, and the axis of the short cylinders is perpendicular to the horizontal plane, such as image 3 . The support is composed of symmetrical left support 2 and right support 3. The left support 2 and the right support 3 respectively have support sl...

Embodiment 2

[0043] Another structure of the turning tool in this embodiment is different from the first embodiment in that the short cylinders are set on the two slopes of the left support and the right support, and the cylindrical holes are set on the two slopes of the inner groove of the tool body. In addition, there is a 20-degree oblique angle between the line connecting the short cylinder and the cylindrical hole in each row and the length direction of the cutter body, such as Figure 14-18 ; Other structures are the same.

[0044] When adjusting the center height of the cutter body, when the cutter body moves along its length direction with a cylindrical hole spacing of 0.15 mm, let the short cylinder insert into the cylindrical hole, and support the cutter body through the support. Such as Figure 19 , 20, according to the relationship of the triangle, if the axis distance of the two shorts is 0.15 mm, and the inclination angle of the connecting line between the two shorts is 20 ...

Abstract

The invention discloses a reverse inclined plane contact type height adjustable lathe cutter with bulge sharp teeth. The reverse inclined plane contact type height adjustable lathe cutter comprises acutter body and a supporting part, the bottom of the cutter body is provided with a groove in the length direction of the cutter body inwards, the groove is provided with two symmetrical inclined planes gradually adducted from outside to inside, the supporting part comprises a left support and a right support, the left support and the right support are provided with inclined planes consistent withthe cutter body inclined planes correspondingly, provided with a plurality of corresponding tenon blocks and concave platforms correspondingly and are inlaid and closed together through the sharp teeth on the surface, the inclined planes of the cutter body or the supporting part are provided with a plurality of rows of short columns and holes, the short columns can be inserted into the holes, thecutter body and the inclined planes of supporting part are made to contract tightly, and installation of the lathe cutter is finished; and the position of the cutter body is changed, the short columns in rows are made to be inserted into the holes in other rows, and adjustment of the height of the lathe cutter is realized. The reverse inclined plane contact type height adjustable lathe cutter with bulge sharp teeth can adjust the center height conveniently, accurately and in steps, is convenient to operate and has high practicability.

Description

technical field [0001] The invention belongs to the technical field of turning tools, and relates to turning tools used in common lathes and numerically controlled lathes, in particular to a bevel contact type height-adjustable turning tool with protruding tines. Background technique [0002] Lathes (including ordinary lathes and CNC lathes) require that the tool tip of the tool must be at the center height of the rotating part during processing, otherwise the actual rake angle and rear angle of the tool cutting will be changed because the tool is not at the center height, or the part will be cut during cutting. It cannot be cut off, and it is very easy to cause a knife. After the traditional tool is manufactured, the center height of the tool is fixed. For welded turning tools, after the tool is sharpened, especially after the rake face is sharpened, the actual center height of the installed tool will become lower. The traditional method is to use some gaskets with differe...
