Abstract
A cutter chuck for a numerically-controlled machine tool comprises a main shaft, a clamping jaw driving piece, three clamping jaws, an upper shell, a clamping jaw base and a lower shell. One end of the main shaft is provided with a driving connecting part. The other end of the main shaft is a connecting-combining hole. Inner threads are arranged in the connecting-combining hole. A connecting column with the outer threads screwed with the inner threads is arranged at the upper end of the clamping jaw driving piece. The lower end of the clamping jaw driving piece is a clamping jaw abutting part. The upper ends of the clamping jaws abut against the lower end of the clamping jaw abutting part. The upper shell is combined to the outer periphery of the main shaft in a combining mode and can rotate freely. One end of the clamping jaw base is arranged to the clamping jaw abutting part in a penetrating-sleeved mode and is contained in the upper shell, and the other end of the clamping jaw base is a cone part. The cone part is provided with three clamping jaw sliding grooves correspondingly. The lower shell is combined outside the clamping jaw base in a sleeved mode and is fixedly connected with the upper shell. A cone-shaped inner wall is arranged in the lower shell and is matched with the cone part of the cone part of the clamping jaw base. Accordingly, a cutter is effectively clamped, the abrasive resistance and the oxidation resistance are improved, and service life is prolonged.
Description
Technical field
The present invention relates to a kind of Digit Control Machine Tool cutter chuck.
Background technology
Along with expanding economy, the demand of manufacturing industry constantly increases, in order to raise the efficiency and reduce costs, application lathe carries out being machined to better selection, and manufactures efficiency and product effect to improve further, then need the introduction of digital control processing, and when digital control processing, extremely important to the clamping of cutter, effectively should clamp, also will realize resistance to wearing with anti-oxidant in processing.
For this reason, designer of the present invention is because above-mentioned defect, and by concentrating on studies and designing, comprehensive experience and the achievement being engaged in related industry for a long time for many years, research and design goes out a kind of Digit Control Machine Tool cutter chuck, to overcome above-mentioned defect.
Summary of the invention
The technical problem to be solved in the present invention is: when digital control processing, extremely important to the clamping of cutter, should effectively clamp, and also will realize resistance to wearing with anti-oxidant in processing.
For solving the problem, the invention discloses a kind of Digit Control Machine Tool cutter chuck, it is characterized in that comprising:
One main shaft, one end of described main shaft is for driving connecting portion, and to connect a driving shaft, the other end is conjugate foramen, has internal thread in described conjugate foramen, and the periphery of described main shaft is convexly equipped with flange;
One jaw actuator, its upper end is have the externally threaded joint pin with above-mentioned internal screw-thread screw, and lower end is jaw butting section;
Three jaws, the upper end of described jaw is resisted against the lower end of described jaw butting section;
Upper casing, described upper casing is sleeved on the periphery of described main shaft and can freely rotates;
Jaw seat, one end of described jaw seat is set in above-mentioned jaw butting section and is contained in described upper casing, and the other end is conus portion, and described conus portion correspondence is provided with three above-mentioned jaws of confession and is located in interior and at the jaw chute of interior slip;
Lower casing, be sleeved on described jaw seat outer and be connected and fixed with described upper casing, the inside of described lower casing is provided with a taper inwall, to match with the conus portion of described jaw seat;
The surface of each jaw is provided with wearing layer.
Wherein: also comprise a bearing, be located between the ladder inwall of described upper casing and the flange of main shaft.
Wherein: described wearing layer is titanium oxide wearing layer, titanium nitride wearing layer or titanium carbide wearing layer.
Known by said structure, Digit Control Machine Tool cutter chuck of the present invention has following technique effect:
1, cutter is effectively clamped;
2, improve wearability and non-oxidizability, improve service life.
Detailed content of the present invention obtains by explanation described later and institute's accompanying drawing.
Accompanying drawing explanation
Fig. 1 shows the structural representation of Digit Control Machine Tool cutter chuck of the present invention.
Fig. 2 shows action schematic diagram of the present invention.
Detailed description of the invention
See Fig. 1 and Fig. 2, show Digit Control Machine Tool cutter chuck of the present invention.
Described Digit Control Machine Tool cutter chuck comprises:
One main shaft 10, one end of described main shaft 10 is for driving connecting portion 11, and to connect a driving shaft, the other end is conjugate foramen 12, has internal thread in described conjugate foramen 12, and the periphery of described main shaft 10 is convexly equipped with flange 13.
One jaw actuator 20, its upper end is have the externally threaded joint pin 21 with above-mentioned internal screw-thread screw, and lower end is jaw butting section 23.
Three jaws 30, the upper end of described jaw is resisted against the lower end of described jaw butting section 23.
Upper casing 40, described upper casing 40 is sleeved on the periphery of described main shaft 10 and free to rotate.
Jaw seat 50, one end of described jaw seat 50 is set in above-mentioned jaw butting section 23 and is contained in described upper casing 40, and the other end is conus portion 51, and described conus portion 51 correspondence is provided with three above-mentioned jaws of confession 30 and is located in interior and at the jaw chute 52 of interior slip.
Lower casing 60, be sleeved on described jaw seat 50 outer and be connected and fixed with described upper casing 40, the inside of described lower casing 60 is provided with a taper inwall, to match with the conus portion 51 of described jaw seat 50.
And a bearing 70, between the ladder inwall 41 being located at described upper casing 40 and the flange 13 of main shaft 10.
Wherein, see Fig. 2, when described main shaft rotates, because main shaft can not move, its internal thread drives described jaw actuator to move up and down, and thus, jaw is also thereupon mobile to clamp cutter.
