Embodiment Construction

[0030] The accompanying drawings disclose the specific structures of the embodiments of the present invention without limitation, and the present invention will be further described below in conjunction with the accompanying drawings.

[0031] Depend on figure 1 It can be seen that the present invention is composed of three parts: a shrink disc device, a tool feed adjustment device and a clamping accessory. The shrink disc device includes a shrink ring 1, an adjusting bolt 3 and a tapered hole cutter head 4. The shrink ring 1 is composed of a ring It is composed of a seat and a conical shrinking flap containing a shrinking groove. The center of the tapered hole cutter head 4 is a tapered hole. In the hole, the adjustment bolt 3 on the shrink ring seat is tightly connected with the tapered hole cutter head 4; the tapered hole cutter head is provided with an installation notch for the tool feed adjustment device. During specific implementation, in the installation notch There s...

Abstract

The invention relates to an adjustable boring cutter head and a method for changing the feed rate of the cutter head. The adjustable boring cutter head comprises a shrink disk device, a tool feed adjusting device and a clamping accessory, wherein the shrink disk device comprises a shrink ring, an adjusting bolt and a taper hole cutter head, the tool feed adjusting device comprises a positioning tray, a lead screw, a bearing bush, a bearing, a rotating handle and an adjusting quantity indicating mechanism, and the clamping accessory comprises a dovetail groove body and a boring tool clamp. A boring tool is fixedly mounted at the top end of the boring tool clamp. The method for changing the feed rate includes the steps: returning the boring cutter head to a machining starting position alonga spindle after completing previous boring; determining a starting scale mark for adjusting the feed rate; loosening a fastening screw on the dovetail groove body in a mounting notch, and driving a pointer to rotate for pointing at a new scale mark in a dial by adjusting the lead screw through the handle to obtain a new feed rate of the boring tool; and finally positioning a dovetail boss on the dovetail groove body into a corresponding dovetail groove.

Description

technical field [0001] The invention relates to a boring cutter head and a method for changing the feed rate thereof, in particular to a method for directly adjusting the feed rate of the next boring cutter through a handle without re-correcting the tool after each feed of the boring processing is completed. Boring cutter head with high cutting capacity. Background technique [0002] With the rapid development of my country's industry, under the requirements of high technology and high production efficiency, the development and improvement of its production equipment are constantly promoted, and at the same time, higher requirements are put forward for the processing accuracy of the equipment. As the key equipment for product processing, the boring machine usually has a machining accuracy that directly determines the accuracy of the entire set of products, and its role is irreplaceable. [0003] At present, there are many kinds of boring machines manufactured in the world, ...
