Description

 The invention relates to metalworking and can be used in prefabricated cutting tools.

Known devices for eliminating (regulating) the runout of elements of metal cutting machines, including the cutting edges of the inserts in a multi-blade cutting tool by introducing into their design a damping device with various dissipative forces [1]
A device is also known for controlling the face runout of cutting edges of inserts in a multi-blade cutting tool by turning the eccentric fingers that are located in the cutting tool body [2]
The closest in technical essence and the achieved result is a device for regulating the face runout of the cutting edges of the inserts in a multi-blade prefabricated cutting tool, containing a flexible element in the tool body, designed to interact with the face of the cutting insert or cartridge containing it, and a screw with a conical head installed in the threaded hole of the housing and designed to interact with the pliable element [3]
The disadvantage of this device is that it does not provide uniform deformation of the compliant element, which leads to the appearance of non-rigid joints of the cutting insert or cartridge containing it, with the cutting tool body. This disadvantage affects the quality of regulation of the face runout of the cutting edges of the inserts, which leads to a decrease in both productivity and the quality of metalworking.

 The basis of the present invention is the task of improving the quality and productivity of metalworking by eliminating non-rigid joints between the cutting insert or the cartridge containing it, and the body of the multi-blade cutting tool, which will allow you to adjust the face runout of the cutting edges of the inserts in the multi-blade cutting tool in the required range.

 The essence of the invention lies in the fact that in the device for regulating the end runout of the cutting edges of the inserts in a multi-blade prefabricated cutting tool containing a flexible element in the element casing, designed to interact with the edge of the cutting insert or cartridge containing it, and a screw with a conical head installed in a threaded hole of the housing and designed to interact with the compliant element, an oval funnel-shaped opening is made in the housing, in which the said conical head is placed Inta and pliant element formed as a bridge in the casing.

 In FIG. 1 shows a fragment of a device for regulating the end runout of cutting edges of inserts in a multi-blade precast cutting tool; in FIG. 2 is a view along arrow A in FIG. 1 after deformation by a conical screw head of a part of the housing in contact with the face of the cutting insert or cartridge containing it, with the formation of a jumper in the housing of the cutting tool.

 A device for controlling the face runout of cutting insert edges in a multi-blade precast cutting tool consists of a cutting tool housing 1, an oval funnel-shaped hole 2 in the housing 1, a screw 3 with a conical head 4, a cylindrical hole 5 with a thread in the housing 1, a contacting face 6 of the cutting insert or cartridge 7 containing it, with a part of the housing 1 of the cutting tool.

 A device for regulating the face runout of the cutting edges of the inserts in a multi-blade precast cutting tool as follows.

 If there is a face runout of the cutting edges of the plates, screw the screw 3 into a cylindrical hole 5 with a thread in the housing 1 until the conical head 4 of the screw 3 deforms the contact point of the housing 1 of the assembled cutting tool until a malleable element in the form of a jumper 8 is formed and non-rigid is eliminated the joint or the resulting gap 9 (see Fig. 2) between the housing 1 and the upper face of the cutting insert 7. The uniformity of deformation of the contact point of the housing 1 with the contacting face of the cutting insert or cartridge 7, e e containing, provide due to the oval cross-section of the funnel-shaped hole 2 and the conical head 4 of the screw 3. If you exclude a non-rigid joint and the gap 9 between the housing 1 and the contacting face 6 of the cutting insert or cassette containing it, the imposition of harmonic oscillations with close frequencies, that is, beating is excluded.

 Providing the ability to control the face runout of the cutting edges of the inserts in a multi-blade precast cutting tool will increase the durability of the cutting insert with an increase in the quality and productivity of metal processing.
