Disclosure of Invention

The utility model aims at having the above-mentioned problem to current technique, provided a carving and milling machine, the utility model discloses solve the problem that current carving and milling machine machining precision is low.

The purpose of the utility model can be realized by the following technical proposal:

the utility model provides a carving mills machine, includes the frame, the frame is including the supporting part that is located the rear side and can follow the horizontal layer board of supporting part lateral reciprocating motion, a serial communication port, horizontal layer board is located the top surface of supporting part, the front side that is provided with bracket component and bracket component on the horizontal layer board is connected with the cutter frame of protrusion in the supporting part forward, the bracket component has the focus of being partial to the supporting part rear side, makes the whole focus behind the bracket component connection cutter frame is located the supporting part directly over the position, the bracket component is made by metal material.

Set up horizontal layer board in this patent on the top surface of supporting part, because the top surface that has the supporting part resists the action of gravity to support, even the overlength that sliding structure (for example lead screw or guide rail etc.) set up between the two at horizontal layer board along the horizontal reciprocating motion's of supporting part in-process so can not produce the microbending phenomenon at the middle part because cutter frame gravity influences yet, guaranteed the precision of removal effectively, and then guarantee the machining precision. In addition, this patent still is provided with the bracket component that the focus is partial to the supporting part rear side on horizontal layer board, the focus position through the bracket component can realize adjusting the atress of horizontal layer board top, the bracket component can be adjusted to a certain extent promptly because the focus of toolframe is located the front side of supporting part and the phenomenon of heeling that causes, make on the horizontal layer board whole focus that bracket component and toolframe formed be located the supporting part directly over the position be unlikely to too the antedisplacement, avoid because toolframe etc. establish at the anterior just heavier horizontal reciprocating sliding to horizontal layer board of weight of supporting part and cause too big frictional force or resistance of heeling, prevent to cause the jamming unsmooth, further improve and remove accurate and machining precision.

Even if the bracket assembly is added, the horizontal supporting plate is supported on the top surface of the supporting part and is supported by the top surface, so the gravity of the bracket assembly is increased without further aggravating the influence of skew and the like. The rear-biased part here means that it can be located completely outside the rear of the part, or it can be located in a corresponding plane at a position that is offset to the rear of the part itself. And link to each other cutter frame and bracket component, not only can realize adjusting the overweight of violence of horizontal layer board, can reduce the vibrations reaction force influence of cutter frame itself in the use equally for the tool bit can more accurate removal guarantee machining efficiency.
