Abstract
The utility model provides a kind of machine tool, belongs to field of mechanical technique.It solve its knife bar of existing machine tool together with cutter head in use easily drop cause cutter head and workpiece damage problem.This machine tool comprises handle of a knife and the knife bar in order to fixing cutter head, and handle of a knife has stiff end and link, and handle of a knife is arranged on lathe by stiff end, and knife bar has connecting portion, and described connecting portion is threaded by helicitic texture with above-mentioned link.This machine tool has the advantage that its knife bar in use can not drop together with cutter head.
Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of machine tool.
Background technology
Cutter in existing lathe generally comprises and is arranged on the handle of a knife on lathe and the knife bar in order to fixing cutter head, because tool bit abrasion needs change and change different cutter heads according to different process requirements, for the ease of changing cutter head, removably connect between its knife bar and handle of a knife.Its connected mode is adopt in handle side walls, open several screwed hole (being generally three) mostly at present, handle of a knife has installation inner chamber, knife bar stretches into be installed inner chamber and then stretches in screwed hole to tighten by bolt and withstand knife bar lateral wall and realize being fixedly connected with between handle of a knife and knife bar, its Problems existing: in use, because cutter can constantly vibrate at work, its bolt easily drops out, thus knife bar drops together with cutter head and causes the damage of cutter head and workpiece.
Summary of the invention
The utility model is the problems referred to above existed for existing technology, provides the machine tool that its cutter head knife bar a kind of in use can not drop.
The purpose of this utility model realizes by following technical proposal: a kind of machine tool, comprise handle of a knife and the knife bar in order to fixing cutter head, described handle of a knife has stiff end and link, handle of a knife is arranged on lathe by stiff end, it is characterized in that: described knife bar has connecting portion, described connecting portion is threaded by helicitic texture with above-mentioned link.
In above-mentioned a kind of machine tool, described helicitic texture comprises the installing hole with internal thread hole structure being opened in link and the connector with external thread structure be located on the outer end of above-mentioned connecting portion, and described connector is threaded with installing hole.
In above-mentioned a kind of machine tool, described link has inner chamber, and above-mentioned mounting hole site is in the bottom of inner chamber, and knife bar connecting portion stretches in above-mentioned inner chamber.
In above-mentioned a kind of machine tool, described knife bar connecting portion and the inner chamber interference fit of handle of a knife link.
Compared with prior art, this machine tool has following several advantage:
1, thread connecting mode between its handle of a knife and knife bar, makes to connect between handle of a knife and knife bar more firm, uses middle knife bar to depart from handle of a knife and falls down and make cutter head or workpiece damage;
2, the over-surplus fit structure of knife bar connecting portion and handle of a knife link inner chamber, makes to connect contact surface between handle of a knife and knife bar larger, connects more stable firm.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is Knife handle structure schematic diagram.
Fig. 3 is lever structure schematic diagram.
In figure, 1, handle of a knife; 11, link; 12, installing hole; 13, inner chamber; 2, knife bar; 21, connecting portion; 22, connector.
Detailed description of the invention
Be below specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As shown in Figure 1, this machine tool comprises handle of a knife 1 and the knife bar 2 in order to fixing cutter head, and handle of a knife 1 has stiff end and link 11, and handle of a knife 1 is arranged on lathe by stiff end, and knife bar 2 has connecting portion 21.
Further, as shown in Figure 2, link 11 has the installing hole 12 with internal thread hole structure, link 11 has inner chamber 13, and installing hole 12 is positioned at the bottom of inner chamber 13; As shown in Figure 3, the outer end of connecting portion 21 is provided with the connector 22 with external thread structure.As shown in Figure 1, knife bar 2 connecting portion 21 to stretch in inner chamber 13 and interference fit, and connector 22 extend into bottom inner chamber 13 and is fixedly connected with installing hole 12 screw thread.
Thread connecting mode between its handle of a knife 1 and knife bar 2, makes to connect between handle of a knife 1 and knife bar 2 more firm, uses middle knife bar 2 can not depart from handle of a knife 1 and falls down and make cutter head or workpiece damage;
The over-surplus fit structure of knife bar 2 connecting portion 21 and handle of a knife 1 link 11 inner chamber 13, makes to connect contact surface between handle of a knife 1 and knife bar 2 larger, connects more stable firm.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present utility model or surmount the scope that appended claims defines.
