Description

Floating type milling cutter

Technical Field

The utility model relates to the field of milling cutters, in particular to a floating type milling cutter.

Background

Milling is one of the most common machining methods, and when milling a large plane, a disc cutter is usually used for milling,

if the plane of product is not level, will lead to the condition emergence that the cutting output is different, when the cutting output is too big or undersize, can mill the rotational speed through the change, feed rate, the cutter head height changes the cutting output, but all need people to intervene usually, and is comparatively troublesome, and inefficiency often can cause the cutter to damage and motor overload to arouse the damage because the cutting output adjustment is untimely.

The inventor invents a floating type milling cutter, so that the milling cutter can automatically lift the cutter when the cutter consumption is large, and the existing problems are solved.

Disclosure of Invention

In order to solve the problems, the utility model provides a floating type milling cutter, which adopts the following technical scheme:

the utility model provides a floating milling cutter, includes blade disc, blade, handle of a knife and cutter arbor, the cutter arbor install between handle of a knife and the blade disc, be equipped with two at least bosss on the outer wall of cutter arbor, the cutter arbor in open and to have the locking screw hole, the blade disc on open and to have the cross connection hole, the cross connection hole inner wall on be equipped with two at least recesses, the recess with the boss phase-match, the blade disc with the cutter arbor can dismantle the connection, the lower terminal surface of blade disc is opened and is had the mounting hole, the mounting hole be half counter bore, the blade install the blade disc on the outer wall of cutter arbor has cup jointed the spring.

Further inject, be equipped with eight bosss on the outer wall of cutter arbor, the cross-under hole inner wall on be equipped with eight recesses, the contact range is more, frictional force is bigger, the more firm of connection.

Further, the cutter bar and the cutter head are connected together in a threaded connection mode.

Further inject, still including the gasket, the external diameter of gasket is greater than the diameter of cutter arbor, through the threaded connection mode of anti-hanging can be effectual with cutter head and cutter arbor link together.

Compared with the prior art, the utility model has the following advantages:

1. the floating cutter head can be controlled by programming to automatically lift the cutter when the cutter consumption is large during milling.

2. The cutter head and the cutter rod are connected more firmly.
