The double shaft precision rotary table provided by the utility model has the advantages that the part manufacture and processing is simple; the disassembly is convenient due to hub linkage, and when the double shaft precision rotary table is mounted, the hub can be conveniently regulated to a needed position on the shaft, the service life is long, the strength is high, the load bearing capability is strong, and the transmission precision of the worktable is high.

Description

Dual spindle accurate rotating platform
Technical field
The utility model relates to the Digit Control Machine Tool turntable, relates in particular to a kind of dual spindle accurate rotating platform.
Background technology
The propeller boss connecting mode of tradition numerical control rotating platform mainly is singly-bound connection, splined, interference fit connects and pin connects.Singly-bound connects, the splined major defect is to connect the gap can't overcome, and can't overcome processed complex to the weakening of axle; Interference fit connects higher to requirement on machining accuracy, also needs corresponding heating, cooling or pressurized equipment during assembling; The intensity that pin connects is not high, can't overcome the weakening of axle, and technology is relatively backward.
The utility model content
The purpose of this utility model is: a kind of dual spindle accurate rotating platform is provided, and part manufacturing processing is simple, and propeller boss connects, convenient disassembly, can conveniently wheel hub adjusted to desired location epaxially; Long service life, the intensity height, it is strong to bear load-bearing capacity.
The technical solution of the utility model is: a kind of dual spindle accurate rotating platform, it is included in A axle main shaft, the C pedestal that rotates around the A axle under the effect of A spindle motor, described C pedestal is provided with under the effect of C spindle motor the workbench around the rotation of C axle, overlaps by swelling between A axle main shaft and the C pedestal and fixedlys connected.
Below technique scheme is further detailed:
Be fixedly connected with adpting flange on the described A axle main shaft, fixedly connected by the swelling cover between adpting flange and the C pedestal 4.
Described A spindle motor is an A axle torque motor.
Described C spindle motor is a C axle torque motor.
Described A axle torque motor is arranged on the lathe.
Described C axle torque motor is arranged on the C pedestal.
Described workbench is fixedlyed connected with the main shaft of C axle torque motor.
The utility model has the advantages that:
1, dual spindle accurate rotating platform of the present utility model has adopted the swelling connecting mode, connects with general interference fit joint, singly-bound, pin connects and compare, and have the advantage of many uniquenesses: (1) swelling connects makes the main frame part make and install simple.Hole and axle that the swelling cover is installed do not have interference fit to connect the manufacturing tolerance that requires machining high-precision like that.The swelling cover connects easy to adjust, wheel hub can be adjusted to desired location easily on axle.(2) long service life of swelling cover, the intensity height.Rely on frictional drive that connected body is provided with keyway and weaken phenomenon, no relative motion can not produce friction in the work.When (3) swelling is enclosed within overload, will lose anastomosis, and can be without prejudice by protection equipment, the swelling cover connects can bear multiple load.(4) swelling is overlapped convenient disassembly and is had good interchangeability.Because the swelling cover can combine the bigger propeller boss of fit clearance, during dismounting bolt is unclamped and connected body can be separated.
2, dual spindle accurate rotating platform of the present utility model, the transmission of preferred employing bimoment motor, make all kinematic axis of lathe have higher dynamic property and control characteristic, thereby provide optimum condition to the processing mold free form surface for high-speed, high accuracy and great surface quality.
3, dual spindle accurate rotating platform of the present utility model preferably adopts the transmission of bimoment motor, and its torque motor drive path is short, workbench and rotor directly link, and the signal by the high resolution encoder of rotor direct connection produces directly acts on workbench, therefore, the workbench transmission accuracy is higher; And, the angular acceleration that torque motor can reach than traditional worm and gear transmission up to 6 times; Torque motor can reach high static state and dynamic load rigidity, thereby has improved the positioning accuracy and the repetitive positioning accuracy of gyroaxis and swinging axle.
Description of drawings
The utility model will be further described below in conjunction with drawings and Examples:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the B portion enlarged diagram among Fig. 1.
Wherein: 1A axle torque motor; 2 connect an orchid; 3 swelling covers; The 4C pedestal; 5C axle torque motor; 6 workbench; 7 bearing blocks; 8A axle main shaft; The main shaft of 9C axle torque motor.
The specific embodiment
Embodiment: as shown in Figure 1, a kind of dual spindle accurate rotating platform, it comprises A axle torque motor 1, C pedestal 4, C axle torque motor 5, workbench 6, bearing block 7.
A axle torque motor 1 is identical with bearing block 7 external forms structure, is respectively installed to (on the both sides gantry upright post as portal frame) on the lathe.
C pedestal 4 is connected on the main shaft 8 of A axle torque motor 1 by swelling cover 3 and adpting flange 2 on one side.Specifically can be with reference to figure 2, adpting flange 2 is fixed on by screw on the main shaft 8 of A axle torque motor 1, overlaps 3 by swelling between adpting flange 2 and the C pedestal 4 and fixedlys connected.According to identical structure and principle, the another side of C pedestal 4 is connected on the main shaft of bearing block 7 by swelling cover 3 and adpting flange 2.
C pedestal 4 can rotate around the A axle under the effect of A axle torque motor 1, becomes the swinging axle parts.Workbench 6 is screwed on the main shaft 9 of C axle torque motor 5, rotates around the C axle at the effect lower table 6 of C axle torque motor 5, becomes the rotary table parts.And C axle torque motor 5 is fixed on the C pedestal 4, rotates around the A axle with the C pedestal.
Under the situation of two axle interlocks, the part that is fixed on the workbench 6 can rotate around A, C axle simultaneously.Entire mechanism constitutes two precise rotating platform systems.
Should be pointed out that for the utility model also to have the embodiment of multiple conversion and remodeling, be not limited to the specific embodiment of above-mentioned embodiment through proving absolutely.The foregoing description is as just explanation of the present utility model, rather than restriction.In a word, protection domain of the present utility model should comprise those conspicuous to those skilled in the art conversion or substitute and remodeling.
