Abstract

The utility model relates to a dividing spindle servo mechanism used for processing heavy shaft parts. The servo mechanism consists of a driving rotary table (1), a hydraulic floating support (2), a centre frame (3) and a tail seat (4), wherein, the driving rotary table (1) and the tail seat (4) are supported at the two ends of a workpiece (5), and the hydraulic floating support (2) and the centre frame (3) are supported at the lower end of the workpiece (5). The positioning accuracy of the servo mechanism is high, and the bearing of the rotary driving torque of the complete mechanism is huge, therefore, the utility model is very suitable for processing heavy shaft parts; the cost can be effectively reduced; and compared with the prior common dividing spindle servo mechanism, the utility model has the advantages of high efficiency, large driving torque and good supporting rigidity.

Description

The dividing spindle servo control mechanism of heavy Machining of Shaft-type Parts
Technical field
The utility model belongs to large-sized numerical control Longmen machine tool field of components, particularly relates to a kind of dividing spindle axle servo control mechanism of part processing.
Background technology
The processing of axial workpiece, mainly on horizontal lathe, carry out, if axial workpiece is carried out the excircle Milling Process, such as milling cylindrical helicla flute, then need lathe to have dividing spindle and milling s function, and be necessary for numerically controlled lathe, and it is generally less with the lathe milling shaft power of milling s function, when requiring the high-efficiency high-power cutting, just must adopt the turning milling center of milling function such as the band whirlwind, cost is very high; Under situation with good conditionsi, adopt the engine lathe processing excircles, the method that goes up the milling of numerical control gantry milling-boring machine again can effectively reduce cost, raises the efficiency, just need install dividing spindle servo turning mechanism additional this moment on the numerical control gantry milling-boring machine, also promptly general said the 4th turntable.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of dividing spindle servo control mechanism of heavy Machining of Shaft-type Parts, with the problem of the excircle Milling Process that solves existing large-sized numerical control gantry machining center counterweight profile shaft class part.
A kind of dividing spindle servo control mechanism of heavy Machining of Shaft-type Parts, form by driving turntable (1), hydraulic floating support (2), centre frame (3) and tailstock (4), described driving turntable (1) and tailstock (4) are supported on the two ends of workpiece (5), and hydraulic floating support (2) and centre frame (3) are supported on the lower end of workpiece (5).
Described driving turntable (1) comprises that servomotor (11) connects the low back clearance reduction box (12) of alpha high accuracy and connecting main shaft (14) by reduction gearing (13), main shaft (14) front end is equipped with major diameter hydraulic power chuck (15), chuck (15) drives workpiece (5) revolution, and round grating is equipped with in main shaft (14) rear end.
Described centre frame (3) comprises the roller bearing (31) and the two-way trapezoidal screw (32) of two supporting workpieces (5) for manually adjusting centre frame.
Beneficial effect
The utility model by the circle grating detect, the feedback angle signal, positioning accuracy can reach ± 15 "; Sleeve mechanism revolution driving torque maximum can reach 10250NM, and the chuck clamping force can reach 270KN, and the diameter of work maximum can reach 500mm maximum weight 10T, is fit to very much the heavy axial workpiece of processing; Can effectively reduce cost, compare dividing spindle servo turning mechanism at present commonly used, have efficient height, driving torque is big, rigidity of support is good advantage.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is for driving the turntable structure schematic diagram;
Fig. 3 is the centre frame structural representation.
The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
Embodiment 1
A kind of dividing spindle servo control mechanism of heavy Machining of Shaft-type Parts, support 2, manually can adjust centre frame 3 and tailstock 4 is formed by driving turntable 1, hydraulic floating, described driving turntable 1 and tailstock 4 are supported on the two ends of workpiece 5, and hydraulic floating supports 2 and manually can adjust the lower end that centre frame 3 is supported on workpiece 5; Described driving turntable 1 comprises servomotor 11, servomotor 11 is after the low back clearance reduction box 12 of alpha high accuracy slows down, power is passed to the reduction gearing 13 that has gap-eliminating structure, through further slowing down, be delivered on the main shaft 14, the major diameter hydraulic power chuck 15 of drive shaft 14 front ends drives workpiece 5 revolutions, and detects, feeds back angle signal by the round grating of main shaft 14 rear ends, hydraulic floating supports 2 and has manual height and regulate, and can be under hydraulic pressure supports jack-up; Manually can adjust the roller bearing 31 of centre frame 3 with two supporting workpieces 5, roller bearing 31 centre-to-centre spacing can manually be adjusted by two-way trapezoidal screw 32, to adapt to the needs of different workpieces; Tailstock 4 sleeves are extended under hydraulic action, cooperate supporting workpiece 5 two ends with driving turntable 1.
During use according to following steps:
A) adjust pressure and the height that hydraulic floating supports according to workpiece weight and diameter, making the unsteady support force summation that supports of all hydraulic is about 90% of workpiece weight.
B) workpiece is slowly winched between driving turntable and the tailstock with driving, by hydraulic floating supported workpiece, adjust the workpiece centre height with driving, be located at and drive near turntable and the tailstock center height, the gripper chuck clamping of workpieces, barrel of tail stock stretches out top tight workpiece, makes its center line consistent with turntable and tailstock.
C) adjust centre frame, supporting workpiece is transferred to the weight of floating on supporting on the centre frame, and removing floats supports.
D) draw table workpiece side bus and Up Highway UHW, adjust centre frame, make side bus and Up Highway UHW and X-axis line parallel, unclamp tailstock and chuck, clamp again, detection side bus and Up Highway UHW again, the not parallel above-mentioned steps that repeats again, parallel just the beginning processed.
