Abstract
The present invention relates to a spindle elevating device of a woodwork vertical spindle milling machine. The elevating device comprises a motor, a spindle, an inner elevating cylinder and a sleeve. The spindle is arranged in the inner elevating cylinder, and rises and falls with the inner elevating cylinder along the sleeve. One side of a support plate is fixedly connected with the motor, and the other side is connected with the inner elevating cylinder of the spindle. A threaded nut fixed on the support plate is connected with an elevating screw rod. A worm bracket is fixed on the sleeve, the elevating screw rod, a thrust bearing and a worm are connected with the worm bracket by flat keys and nuts, and a worm is engaged with a worm gear by the worm bracket. The worm, the worm gear and the elevating screw rod are driven to rotate by rotating a hand wheel. The support plate, the motor, the spindle and the elevating screw rod are driven by the threaded nut to simultaneously rise and fall along the elevating screw rod. The requirement of spindle milling machines for spindle elevating accuracy is met. The present invention has the advantages of simple structure, easy operation, accurate spindle elevation position and stable and reliable running.
Description
Technical field
The present invention relates to a kind of woodworking machinery, a kind of specifically spindle elevating device of woodwork vertical spindle milling machine.
Background technology
We know that existing carpenter's vertical shaft milling machine spindle lifting is to be directly installed on the elevating screw by the lifting handwheel, when operating, and effort and inconvenient.Adopted afterwards by being connected the elevating screw rotation of screw on the rotation drive of a pair of bevel gear and the supporting plate, to realize the lifting of main shaft, because of the main shaft lifting requires steadily, the dimension precision requirement strictness, and bevel gear particularly extends along with wood craft machines in rotation process service time, and two gears engaged are insufficient, can't guarantee the lifting dimensional accuracy of main shaft, moreover this mechanism is in carpenter's vertical shaft milling machine spindle lifting process, effort and not steady.
Summary of the invention
Technical problem to be solved by this invention is to overcome above-mentioned the deficiencies in the prior art, provides a kind of simple in structure, operate light, main shaft lifting true-to-size spindle elevating device of woodwork vertical spindle milling machine.
The technical scheme that the present invention solves the problems of the technologies described above employing is: a kind of spindle elevating device of woodwork vertical spindle milling machine, include motor, main shaft, lifting inner core, sleeve, main shaft is installed in the lifting inner core, together along the sleeve lifting, it is characterized in that: also be provided with supporting plate, elevating screw, endless screw support, worm gear, worm screw, supporting plate one side and motor are connected and fixed, and opposite side is connected with the lifting inner core of main shaft, and screw is fixed on the supporting plate and is connected with elevating screw; Endless screw support is fixed on the sleeve, elevating screw, thrust bearing, worm gear are connected with endless screw support with nut by flat key, worm screw is by endless screw support and worm gear engagement, rotate handwheel and drive worm screw, worm gear and elevating screw rotation, screw drives supporting plate, motor and main shaft, lifting inner core synchronization lifting along elevating screw.
Endless screw support of the present invention is fixed on the sleeve with hex bolts, and worm screw is fixed on the endless screw support by block and hex bolts, and meshes with worm gear.
The present invention is owing to install and fix supporting plate, elevating screw respectively at lifting inner core, sleeve, endless screw support, worm gear, worm screw, and worm screw, worm gear and elevating screw rotate synchronously, and screw drives supporting plate and main shaft, lifting inner core synchronization lifting along elevating screw.Against existing technologies, the present invention is simple in structure, and is simple in structure, operates lightly, and main shaft lifting size is accurate, operates steadily, reliably, satisfied main shaft milling machine spindle lifting dimension precision requirement.
Description of drawings
The present invention will be further described below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the schematic top plan view of Fig. 1.
Label among the figure is: 1. nut, 2. worm gear, 3. flat key, 4. thrust bearing, 5. supporting plate, 6. elevating screw, 7. screw, 8. hex bolts, 9. soket head cap screw, 10. lifting inner core, 11. hex bolts, 12. sleeves, 13. endless screw support, 14. worm screws, 15. hex bolts, 16. blocks, 17. handwheels.
The specific embodiment
As can be seen, a kind of spindle elevating device of woodwork vertical spindle milling machine of the present invention includes motor, main shaft, lifting inner core 10, sleeve 12 from Fig. 1, Fig. 2, and sleeve 12 is fixed on below the workbench of carpenter's vertical shaft milling machine.Main shaft is installed in the lifting inner core 10, together along sleeve 12 liftings.Motor is connected motion with main shaft by belt.
Spindle elevating device of woodwork vertical spindle milling machine of the present invention also includes supporting plate 5, elevating screw 6, endless screw support 13, worm gear 2, worm screw 14, supporting plate 5 one sides and motor are connected and fixed, opposite side is connected with the lifting inner core 10 of main shaft, and screw 7 is fixed on the supporting plate 5 and is connected with elevating screw 6.Specifically be that supporting plate 5 is connected with the lifting inner core 10 of main shaft by soket head cap screw 9, screw 7 usefulness hex bolts 8 are fixed on the supporting plate 5, and are connected with elevating screw 6.Endless screw support 13 is fixed on the sleeve 12, and worm screw 14 is by endless screw support 13 and worm gear 2 engagements.Specifically be that elevating screw 6, thrust bearing 4, worm gear 2 is connected with endless screw support 13 by flat key 3, nut 1, endless screw support 13 usefulness hex bolts 11 are fixed on the sleeve 12, worm screw 14 is fixed on the endless screw support 13 by block 16 and hex bolts 15, and meshes with worm gear 2.Rotate that handwheel 17 drives worm screws 14 and worm gear 2, elevating screw 6 rotates, and then screw 7 moves up and down along elevating screw 6, drive supporting plates 5, motor and main shaft, lifting inner core 10 synchronization liftings, realize the easily steadily lifting of vertical shaft milling machine spindle by screw 7.Satisfied main shaft milling machine spindle lifting dimension precision requirement.The present invention is simple in structure, and is simple in structure, operates lightly, and main shaft lifting size is accurate, operates steadily, reliably.
