Abstract
The CNC planer type milling machine that the utility model provides a kind of screw to rotate, solves the longer leading screw mid portion caused of existing current leading screw easily bending sagging, affects service precision and is not suitable for the problem of high-speed motion.It comprises crossbeam and column, crossbeam is provided with slide plate, slide plate is provided with ram, the two ends of crossbeam are fixed with leading screw holder respectively, by nut, leading screw is fixed on leading screw holder, slide plate is fixed with screw holder, screw is connected with screw holder by bearing, and leading screw matches with screw, slide plate is fixed with motor, the output shaft of motor is fixed with electrical machine belt pulley, screw is fixed with screw belt wheel, electrical machine belt pulley is connected with screw belt wheel by belt.The utility model applies axial pre tightening force to leading screw, overcomes gravity-bending distortion; Rotated by driven by motor screw, can adopt higher linear velocity, leading screw extends service life greatly.
Description
Technical field
The utility model belongs to the CNC planer type milling machine that a kind of screw rotates.
Background technology
In tradition, CNC planer type milling machine adopts leading screw to rotate, screw fixed form, and this kind of mode, in the longer situation of leading screw, is reduced to elongate rod structure, and due to Action of Gravity Field own, leading screw mid portion is easily bending sagging, produces distortion, has a strong impact on service precision.Simultaneously leading screw rotates screw fixed form and is not suitable for high-speed motion, and when rotating speed is higher, screw mandrel shortens service life greatly.
Summary of the invention
The CNC planer type milling machine that the utility model provides a kind of screw to rotate, solves the longer leading screw mid portion caused of existing CNC planer type milling machine leading screw easily bending sagging, and then affects service precision, and be not suitable for the technical problem of high-speed motion.
Technical solution of the present utility model is:
The CNC planer type milling machine that a kind of screw rotates, comprise crossbeam and the column for supporting traverse, the chute described crossbeam being provided with level and the slide plate coordinated with slide, slide plate is provided with the ram that can move up and down, it is characterized in that: the two ends of described crossbeam are fixed with leading screw holder respectively, applying pretightning force by nut to the two ends of leading screw is fixed on leading screw holder by leading screw, slide plate is fixed with screw holder, screw is connected with screw holder by bearing, leading screw matches with screw, slide plate is also fixed with motor, the output shaft of motor is fixed with electrical machine belt pulley, screw is fixed with screw belt wheel, electrical machine belt pulley is connected with screw belt wheel by belt.
The bottom interval of described chute arranges some large oil storage holes and little oil storage hole, is convenient to store lubricating oil.
The utility model has the advantages that:
(1) mode that the screw rotating threaded shaft adopted is fixing, at leading screw two ends, nut fixes leading screw, two ends nut check, applies axial pre tightening force to leading screw, overcomes gravity-bending distortion;
(2) rotated by driven by motor screw, can adopt higher linear velocity, leading screw extends service life greatly.
Accompanying drawing explanation
Fig. 1 is the structural representation of CNC planer type milling machine;
Fig. 2 is the enlarged drawing of leading screw holder;
Fig. 3 is the enlarged drawing that screw is fixed on screw holder;
Wherein: 1. crossbeam, 2. slide plate, 3. ram, 4. leading screw holder, 5. nut, 6. leading screw, 7. motor, 8. electrical machine belt pulley, 9. belt, 10. screw belt wheel, 11. screws, 12. bearings, 13. screw holders.
Detailed description of the invention
The CNC planer type milling machine that a kind of screw rotates, comprise crossbeam 1 and the column for supporting traverse, the chute described crossbeam being provided with level and the slide plate 2 coordinated with slide, slide plate 2 is provided with the ram 3 that can move up and down, the two ends of described crossbeam are fixed with leading screw holder 4 respectively, applying pretightning force by the two ends of nut 5 pairs of leading screws 6 is fixed on leading screw holder 4 by leading screw, slide plate is fixed with screw holder 13, screw 11 is connected with screw holder 13 by bearing 12, leading screw 6 matches with screw 11, slide plate is also fixed with motor 7, the output shaft of motor 7 is fixed with electrical machine belt pulley 8, screw is fixed with screw belt wheel 10, electrical machine belt pulley is connected with screw belt wheel by belt 9.
Preferably, the bottom interval of chute arranges some large oil storage holes and little oil storage hole.
Starter motor, electrical machine belt pulley 8 rotates, belt 9 on electrical machine belt pulley 8 drives screw belt wheel 10 to rotate, the screw 11 be connected with screw belt wheel and then rotate, screw rotates on screw holder, because screw holder is fixed on slide plate 2, thus drive slide plate 2 is relative and crossbeam 1 moves, and finally realizes ram 3 and moves along with slide plate 2 and move.
Claims (2)
