Abstract
The utility model discloses a spindle box of a numerical control floor type boring and milling machine. The spindle box comprises a box body and a square ram. The square ram penetrates through the middle of the box body transversely to be supported in the box body. A spindle is installed in the square ram, a large gear is installed at one end of the spindle, and a transmission box, a planetary transmission and a main transmission servo motor are installed above the square ram. The main transmission servo motor is connected with the planetary transmission connected with a transmission box, a small gear and a middle gear are installed in the transmission box, the small gear is meshed with the middle gear, and the middle gear is meshed with the large gear on the spindle. The spindle box utilizes the main transmission servo motor, the planetary transmission and the transmission box to transfer power to the spindle, drives the spindle to rotate, and is simple in structure, high in transmission efficiency and small in working noise.
Description
Technical field
The utility model relates to a kind of lathe headstock, more particularly, relates in particular to a kind of numerical control landing milling process tool spindle box.
Background technology
Main spindle box is the vitals of cnc boring and milling machine, is mainly used in installing machine tool chief axis and driving parts thereof.The main spindle box of existing large-sized numerical control floor type boring and milling machine, its speed change system are normally closed through the shifting slide gear duplicate invoice by variable speed electric motors, particularly and carry out speed change, because this headstock structure is complicated, the change-speed gearing that uses is many, driving-chain is longer, and transmission efficiency is not high, produces easily noise.
The utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, and a kind of numerical control landing milling process tool spindle box simple in structure is provided, and improves transmission efficiency, reduces noise.
For achieving the above object, numerical control landing milling process tool spindle box provided by the utility model, comprise casing and square ram, side's ram passes from the intermediate lateral of casing, be supported in the casing, in side's ram main shaft is housed, one end of main shaft is equipped with gear wheel, the top of side's ram is equipped with transmission case, planetary transmission and main transmission servomotor, the main transmission servomotor connects planetary transmission, and planetary transmission joint transmission case is equipped with pinion and idler gear in the transmission case, pinion and idler gear engagement, the gear wheel engagement on idler gear and the main shaft.
The utility model by main transmission servomotor, planetary transmission and transmission case with transmission of power to main shaft, drive shaft is rotated, simplify the structure, and planetary transmission can high and low two-shift automatic variable speed, thereby make main shaft realize low-speed big and the purpose that accurately turns round at a high speed, transmission efficiency is high, and operating noise is little.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: the 1-casing; 2-side's ram; The 3-main shaft; The 31-gear wheel; The 4-transmission case; The 41-pinion; The 42-idler gear; The 5-planetary transmission; 6-main transmission servomotor; 7-feed servo motor; The 8-synchronous pulley; The 9-feed screw.
The specific embodiment
The utility model is described in further detail below in conjunction with the embodiment in the accompanying drawing, but do not consist of any restriction of the present utility model.
Consult shown in Figure 1ly, the utility model numerical control landing milling process tool spindle box comprises casing 1 and square ram 2, and square ram 2 adopts existing linear motion guide, passes from the intermediate lateral of casing 1, is supported in the casing 1.
In side's ram 2 main shaft 3 is housed, an end of main shaft 3 is equipped with gear wheel 31; The top of side's ram 2 is equipped with transmission case 4, planetary transmission 5 and main transmission servomotor 6, main transmission servomotor 6 connects planetary transmission 5, planetary transmission 5 joint transmission casees 4, pinion 41 and idler gear 42 are installed in the transmission case 4, pinion 41 and idler gear 42 engagements, gear wheel 31 engagements on idler gear 42 and the main shaft 3.To the gear wheel 31 of main shaft 3, rotate by drive shaft 3 by two gear transmission of main transmission servomotor 6 in planetary transmission 5, transmission case 4 for power.Main transmission servomotor 6 can rotating, planetary transmission 5 high and low two grades of speed (rotating speed output that at a high speed can 1:1 of can automaticallying switch, low speed can 1:20 and above speed reducing ratio output), thus make main shaft 3 realize low-speed bigs and the accurate purpose of running at a high speed.
The outside of side's ram 2 is equipped with feed servo motor 7, synchronous pulley 8 and feed screw 9, feed servo motor 7 connects synchronous pulley 8 by belt, one end of feed screw 9 connects with synchronous pulley 8, the other end stretches in the casing 1 of main spindle box, is driven the auto-feed campaign of feed screw 9 realization side's rams 2 through synchronous pulley 8 by feed servo motor 7.
