Abstract
The invention discloses a numerically controlled lathe capable of improving the traveling direction of a cutter. The numerically controlled lathe comprises the cutter, a base which is used for fixing the cutter, and a first guide rail, wherein the base is in sliding fit with the first guide rail. The numerically controlled lathe is characterized in that: the first guide rail is arranged along the Y-axis direction of the numerically controlled lathe. For the numerically controlled lathe provided by the invention, the position and movement locus of the cutter are improved, and during the movement of the cutter along a Y axis, an actual movement distance is the displacement distance of the Y axis, so that during the cutting of a workpiece, the cutter can quickly return to a proper place, processing time is shortened, and production efficiency is improved.
Description
Technical field
The present invention relates to a kind of numerically controlled lathe, relate in particular to a kind of numerically controlled lathe that improves the cutting knife direct of travel.
Background technology
Numerically controlled lathe is the main product of machine industry, be to realize the modern key equipment of equipment manufacturing the present age, the quantity of China's high-performance numerically controlled lathe and kind a few days ago, still can not satisfy the demand of domestic market, high-tech industry particularly, bearing as China is made the special manufacturer, the efficient numerically controlled lathe of axletree bearing roller still is badly in need of very much, because the machining accuracy height of numerically controlled lathe is advanced in performance, the efficient height adds auxiliary equipment, feeder for example, material receiver can be realized fully-automatic production, and a people manages multiple computer desk, saves a large amount of labours.
Referring to Fig. 1, numerically controlled lathe generally comprises the lathe bed 1 that is positioned on the base in the prior art, also be provided with the main shaft block on the base, the main spindle box of band main shaft is installed on the main shaft block, one end of main shaft has chuck and is used for fixing workpiece 5, the main-shaft axis direction is defined as the Z axle, in order to cut or processing work 5 also is provided with cutting knife 3.The support 2 that has inclined guide rails 4 is installed on the lathe bed 1, cutting knife 3 can move along inclined guide rails 4 by pedestal 6, because cutting knife 3 actual motion tracks are oblique line, displacement on Y-axis is actual motion distance * sin α, α is the inclination angle of inclined guide rails 4, Y-axis displacement in order to obtain to be scheduled to like this, the actual motion of cutting knife 3 distance is longer relatively, consuming time many, production efficiency is not high.
In order to cut off workpiece, also has other two kinds of common cutting knifes mode of advancing in the prior art, wherein a kind of mode is referring to Fig. 2 (being the vertical view of numerically controlled lathe), being provided with on lathe bed can be along the slide plate 23 of X-axis and the slip of Z axle, on the slide plate 23 tool rest is installed, being fixed on this tool rest of cutting knife 22 levels, slide plate 23 need slide along X-axis and Z axle both direction during cutting, make cutting knife 22 from the close position that needs cutting, the side of workpiece 21, and then the cutting of horizontal direction is carried out in feed.
Another mode is referring to Fig. 3 (being the vertical view of numerically controlled lathe), being provided with on lathe bed can be along the slide plate 23 of X-axis and the slip of Z axle, on the slide plate 23 tool rest is installed, cutting knife 22 vertical being fixed on this tool rest, slide plate 23 need slide along X-axis and Z axle both direction during cutting, make cutting knife 33 be in workpiece 21 need cutting part directly over, and then the cutting of Y-axis vertical direction is carried out in feed.
But above dual mode need at first be finished the processing of excircle of workpiece, and then cuts, and is equivalent to two operations, just can finish the processing of whole workpiece, and efficient is lower.
Summary of the invention
The invention provides a kind of numerically controlled lathe, the position and the movement locus of cutting knife improved, improved production efficiency, shortened the process time of workpiece.
A kind of numerically controlled lathe that improves the cutting knife direct of travel, the pedestal that comprises cutting knife and be used for fixing cutting knife is provided with first guide rail, and the described pedestal and first guide rail are slidingly matched, and described first guide rail is arranged along the Y direction of numerically controlled lathe.
Described first guide rail is fixed on the top of the main spindle box of numerically controlled lathe, and described cutting knife be positioned at numerically controlled lathe main shaft directly over.
The top of the main spindle box of described numerically controlled lathe is provided with second guide rail of arranging along Z-direction, is sliding combined with transmission case on second guide rail, and described first guide rail is fixed on the transmission case sidewall.
The servomotor that is provided with leading screw in the described transmission case and is used to drive this leading screw is provided with the spigot nut that cooperates with this threads of lead screw, and described pedestal is fixedlyed connected with spigot nut.
For between the output shaft that improves the described servomotor of machining accuracy and the leading screw by band transmission synchronously.
Described leading screw also is to arrange that along Y direction two ends are installed in the transmission case by bearing.
Described pedestal is provided with the mounting groove of arranging along Y direction, and described cutting knife is fixed in this mounting groove.The sidewall of mounting groove is combined with the bolt that is used for fastening cutting knife by screwed hole.
Numerically controlled lathe of the present invention improves the position and the movement locus of cutting knife, in the processing work cylindrical, just can cut, the lathe tool of processing excircles was overlapped with the time kept in reserve of cutting knife, moreover, when cutting knife moved along Y-axis, actual motion distance was the Y-axis displacement promptly, so cutting knife can be in place rapidly during cut workpiece, shorten process time, improved production efficiency.

The specific embodiment
Referring to Fig. 4,5, the top of the main spindle box 7 of a kind of numerically controlled lathe of the present invention is provided with along being sliding combined with transmission case 15 on second guide rail, 16, the second guide rails 16 of Z-direction layout, and transmission case 15 is connected with driving mechanism, and it can be slided along second guide rail 16.
Be provided with leading screw 10 and servomotor 8 in the transmission case 15, in order to improve machining accuracy, between the output shaft of servomotor 8 and the leading screw 10 by being with 9 transmissions synchronously.
Be provided with the spigot nut 11 with leading screw 10 threaded engagement, spigot nut 11 fixedly connected pedestals 12, pedestal 12 has the gathering sill 18 that matches with first guide rail 17.Leading screw 10 also is to arrange that along Y direction two ends are installed in the transmission case 15 by bearing.
During use, drive motors 8 drives leading screw 10 and rotates, spigot nut 11 is moved up and down along leading screw 10, because the matching relationship of first guide rail 17 and gathering sill 18, cutting knife 13 moves along Y direction, its actual move distance promptly is the moving distance of y-axis shift, also can drive transmission case 15 in addition as required and slide and locking along second guide rail.In the processing work cylindrical, also cut at the position that cutting knife 13 just can need cut near workpiece, and the lathe tool of processing excircles was overlapped with the time kept in reserve of cutting knife, moreover, cutting knife 13 is in place rapid during cut workpiece, has shortened process time, has improved production efficiency.
