SU63941A1 - Self-adjusting cartridge for taps, dies, reamers, etc. - Google Patents

Description

Known for self-aligning chucks for taps, dies, etc. tools, in which the holder, supported by springs allowing for its elastic displacement, is used to fasten the tool. To center the holder and tool with respect to the hole axis at the beginning and at the end of cutting, flat springs were used.

In order to simplify the design of the cartridge according to the invention, instead of flat springs, it is proposed to provide the holder with a conical surface with an adjacent flange. This conical surface and the shoulder, in conjunction with the same surface of the log on the lid of the cartridge, center the holder and, consequently, the tool along the smallpox of the hole being machined.

In the drawing, the proposed cartridge is shown in longitudinal section.

The groove of the housing 1 enters with a gap the holder b, in which the tool 7 is fastened with the screw 7. The pins 2 prevent the holder from rotating relative to the case I. The springs 4, which are located on the studs 3, press the holder 6 to the lid 5. During spring cutting, provide an elastic tool swing and dampen the axial impacts received by the tool during operation.

In order to center the tool along the axis of the hole being machined, the holder 6 is provided with a conical surface 8 and an adjoining flange 9. A cartridge holder 5 is also equipped with corresponding pockets. The interaction of the indicated surfaces of the holder b and the lid 5 ensures that the tool is centered at the beginning and at the end of the cutting.

Subject invention

The self-injecting cartridge for taps, caps, reamers, etc. of the tool with use to secure the tool bypasses pressed by the springs to the cap of the cartridge, in that with the aim of the center of the cage 6 in beginning n at the end of the cut, it is provided with a conical surface 8 n adjacent to Hcii a flange 9, interacting with their corresponding surfaces of the lid 5.
