Description

one

The invention is related to the field of metal processing and can be used for processing curvilinear surfaces on machines with software bar.

In clause 1 of the main author's witness - g ЗБО263, a shaped cutter with mechanical fastening of knives, rotatable in a plane parallel to

axial Ij .;

The disadvantage of this cutter is the IQ inability to rotate the knives in the course of work without stopping the machine, which affects the performance of the machine. .

The goal of the invention was to provide a continuous and intermittent process in the processing process. This is aoctKr feTtsefVTe,: M.TO according to the author’s children's life ZOO263 under item 1 in a mill there is an operation to control the rotation of the knives, consisting of an ascending-20 th in Kopnycie, with a roller, which can be returned with 41 rolls, which can be returned to the opener with a roller, which can be returned by 41 shank associated with the post-slot crank mechanism with each knife.

This zeal ensures continuous rotation of the knives during processing.

FIG. 1 shows an adjustable milling cutter; in fig. 2 - the view along arrow A in FIG. one.

In the case 1 of the cutter, there is a slotted roller 2 fixed with a nut 3. On the roller 2, with its aeii neutral hole, there is installed a shank 4, which is included in the machine tool, in a lateral-axial displacement movement.

In the bores of the housing 1, CBSh is located by hinging 5 with connecting rods in crank1 7, on which knives 8 are mounted, and connecting rods 6 are connected by cylindrical hinges 9 with shank 4.

Mixing the shank 4 with respect to the fixed body 1 with a pinhole, set the knives 8 to a predetermined starting angle. A rotational motion is reported to the mill and, after bringing it into contact with the workpiece, the allowance for processing is removed. mu This leads to a change in the angle between the connecting rod 6 and the crank 7 of each knife 8, the buckle 7, turning, changes the utter position of the blades 8. There is no need to stop the machine, which significantly reduces the loss of machine time and improves the performance of the machine as a whole. In addition, the angular position of the blades can be controlled automatically, which is especially important when machining curved surfaces on digital-program-controlled machines. And, finally, with the help of the claimed cutters, complex surfaces with a variable curvature can be machined, and the installation angle of the knives is constant during the machining process.
