Problems solved by technology

[0002] Lathes (including ordinary lathes and CNC lathes) require that the 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 cutting tool will be changed, or the part cannot be cut during cutting, and it is very easy to cause 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

[0033] Such as figure 1 As shown, it is a structure of the turning tool of the present invention. The lower parts of the two opposite sides in the axial direction (length direction) of the tool body 1 have symmetrical slopes retracting inward, that is, the lower part of the cross section of the tool body along the radial direction is inverted, etc. Waist trapezoidal shape; multiple rows of protruding short cylinders are 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. The supporting member is composed of a symmetrical left support 2 and a right support 3, and the left support 2 and the right support 3 respectively have support inclined surfaces matching with the inclined surfaces of the cutter body. Cylindrical holes are correspondingly arranged on the two support slopes, and the connection line of each r...

Embodiment 2

[0037] Another structure of the turning tool in this embodiment is different from the first embodiment in that the short cylinders are arranged on the two inclined surfaces of the left support and the right support, and the cylindrical holes are arranged on the two inclined surfaces of the lower part of the tool body. In addition, there is a 20-degree oblique angle between the line connecting the short cylinder and the cylinder hole in each row and the length direction of the cutter body; other structures are the same.

[0038] 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. Depend on Figure 13 , 14 It can be seen that the two ends of C1 are the distance between two adjacent short columns, the angle between B1 and C1 is 20 degrees (that is, the angle between the short l...

Abstract

The invention discloses a turning tool with the adjustable contact height of pointed tooth inclined surfaces. The turning tool comprises a tool body and a supporting piece. The lower part of the toolbody is provided with the inclined surfaces. The supporting piece comprises a left support and a right support, and the left support and the right support are correspondingly provided with inclined surfaces matched with the inclined surfaces of the tool body. Multiple rows of protruding short columns are uniformly arranged on the inclined surfaces of the tool body or the supporting piece, correspondingly, holes matched with the short columns are formed in the inclined surfaces of the supporting piece or the tool body, and the short columns can be inserted into the holes so that the inclined surfaces of the tool body and the inclined surfaces of the supporting piece can be in close contact, so that the installation of the turning tool is completed. The height of the turning tool can be adjusted by changing the position of the tool body and inserting the rows of short columns into the holes in other rows. The turning tool can conveniently, accurately and stepwise adjust the center heightand is convenient to operate and high in 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 turning tool with sharp teeth and an adjustable contact height of inclined surfaces. Background technique [0002] Lathes (including ordinary lathes and CNC lathes) require that the 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 cutting tool will be changed, or the part cannot be cut during cutting, and it is very It is easy to cause a knife attack. 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 different thicknesses for installation and adjustmen...
