Embodiment Construction

[0009] Such as figure 1 As shown, the boring tool clamp of the present invention includes a clamp body 3, which is circular, and its center is processed with a rod hole 2 for matching with the tool rod, and its opposite sides have radial flanges 4, two diameters On the same face of the flange 4, a radial groove 5 for installing a cutter is processed. On the outside of the fixture body between the two radial flanges 4 there is an extending ear 1, which is located between the radial flanges 4, and the extending ear 1 is processed with a bolt for clamping the clamp body 3 on the tool bar Horizontal hole. During use, the boring bar stretches into the bar hole 2 in the center by means of the screw holes and bolts on the lug 1, so that the present invention can be tightly fixed on the boring bar. The boring tool is fixed in the radial groove 5 .

Abstract

The invention discloses a boring cutter fixture, in particular to a fixture for mounting a boring cutter, which is particularly suitable for a numerical control boring machine. The boring cutter fixture is characterized by comprising a fixture body; and the fixture body is circular, a rod hole matched with a guide rod is formed in the center of the fixture body, and radial convex edges are formed on two opposite sides of the fixture body, and radial grooves for mounting the cutter are formed in the same surfaces as the two radial convex edges. An extending lug is formed on the outer side of the fixture body between the two radial convex edges; and a transverse hole for clamping the fixture body on the guide rod by means of a bolt is formed in the extending lug. The boring knife fixture has the beneficial effects that the processing precision of a round hole can be improved, and the occurrence of critical phenomenon is avoided.

Description

technical field [0001] The invention relates to a clamp. Specifically, it is a fixture for installing boring tools, especially for CNC boring machines. Background technique [0002] It is known in the machining industry that boring machines are used to process round holes. When using a boring machine for boring, the tool is directly installed on the boring head. When it is necessary to bore a round hole with a large diameter, the machining accuracy is not high due to the large tool extension. And because the tool sticks out a lot when boring a large hole, it is easy to appear the phenomenon of violent knife. Contents of the invention [0003] The problem to be solved by the present invention is to provide a boring tool holder. The use of this boring tool fixture can improve the machining accuracy of the round hole and avoid the phenomenon of sharp cutting. [0004] In order to solve the above problems, the following technical solutions are adopted: [0005] The borin...
