Numerically controlled lathe generally comprises the lathe bed 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, the main-shaft axis direction is defined as the Z axle, by slide plate the base of tool that is used to install lathe tool is installed on the base, and the base of tool can drive lathe tool and move along X-axis, do near or away from the motion of workpiece, can also be provided with the cutting tool that can move along X-axis and Y-axis for cut workpiece.
Some numerically controlled lathes have adopted two main axle structures, two main shafts of layout coaxial or arranged side by side, when processing the two ends of same workpiece, need utilize two main shafts to carry out respectively, when processing a side, need manual workpiece is taken off from a main shaft to be installed on the another one main shaft, in addition, need blanking, tack, cylindrical processing, four operations of cutting in order to finish the processing of a workpiece, just need four operators to utilize four numerically controlled lathes to finish.Equipment and labour's occupancy height have strengthened production cost.
Summary of the invention
The invention provides the numerically controlled lathe of a kind of pair of main shaft, wherein second main shaft can stretch vertically, and the distance of the real-time adjustment and first main shaft is convenient to access workpiece.
The telescopic numerically controlled lathe of a kind of main shaft, comprise first main spindle box and second main spindle box, be respectively equipped with first main shaft and second main shaft in first main spindle box and second main spindle box, first main shaft and the second main shaft coaxial arrangement, the outside of described second main shaft is provided with the sleeve that is slidingly matched vertically with it, this sleeve outer wall is connected with second main spindle box by bearing, second main shaft is with the tail cylinder that is rotatably assorted away from an end of first main shaft, be provided with relatively-stationaryly and along the axial arranged hydraulic cylinder of second main shaft with the second main spindle box position, the piston rod in this hydraulic cylinder is fixedly connected on the tail cylinder.
Hydraulic cylinder both can be fixed on the second main spindle box side, in addition since the tail cylinder by bearing holder (housing, cover) in the second main shaft outside, during piston rod movement, can promote second main shaft by the tail cylinder and in sleeve, slide, and not influence the rotation of second main shaft.
Be provided be used to drive second main shaft with and the motor of outer sleeve.Described sleeve outer wall is fixedly connected with belt pulley, and described motor also can adopt other interlock modes for the rotation that drives second main shaft and sleeve certainly by belt and belt pulley interlock.
The drive circuit of described motor is provided with the switch that is used for the switch motor rotation direction, and described switch inserts and be controlled by the digital control system of lathe by circuit.
Be provided with the keyway arrangements of arranging vertically between the outer wall of described second main shaft and the inwall of sleeve.Make and only can move mutually vertically between second main shaft and the sleeve, and can't rotate mutually, when sleeve rotates, just can drive second main shaft and rotate like this.
Described second main shaft is away from being rotatably assorted by bearing between end of first main shaft and the described tail cylinder.
Described second main shaft is provided with the chuck that is used for holding workpiece near an end of first main shaft.
Second main shaft of numerically controlled lathe of the present invention can stretch, be used near the first main shaft gripping workpiece, by rotating speed or the rotation direction that changes second main shaft, can be when needed and first main shaft make a concerted effort to twist off coupling part residual between workpiece, then second main shaft is come the workpiece gripping that a side machines, and utilizes the opposite side of workpiece processing tool.Automaticity is higher, can a preface finish the processing of workpiece both sides.
Description of drawings
Fig. 1 is the structural representation of second main shaft portion in the numerically controlled lathe of the present invention;
Fig. 2 is second main shaft of numerically controlled lathe of the present invention post exercise structural representation vertically.
The specific embodiment
Referring to accompanying drawing, the telescopic numerically controlled lathe of a kind of main shaft of the present invention comprises first main shaft and second main shaft 1 that are respectively equipped with coaxial arrangement in first main spindle box and second main spindle box, 2, the first main spindle boxes and second main spindle box 2.
Because main the improvement is second main shaft, 1 part, so only shown second main shaft, 1 part among the figure.
The outside of second main shaft 1 is provided with and its sleeve that is slidingly matched vertically 5, these sleeve 5 outer walls are connected with second main spindle box 2 by bearing, second main shaft 1 is with the tail cylinder 9 that cooperates by bearing away from the termination of first main shaft, second main spindle box, 2 sidewalls are fixedly connected with along the axial arranged hydraulic cylinder 4 of second main shaft 1, being fixedly connected on the tail cylinder 9 of the piston rod 8 in this hydraulic cylinder 4.
