Arranging the first motor, the second motor, the 3rd motor, the 4th motor, X-axis leading screw on lathe bed, the two ends of X-axis leading screw are respectively provided with the first workbench, the second workbench;
First motor drive connection the first workbench, the first workbench arranges three-jaw self-centering chuck, and first driven by motor the first workbench and three-jaw self-centering chuck rotate;
Second motor drive connection the second workbench, the second workbench arranges collet, and collet is oppositely arranged with three-jaw self-centering chuck, and second driven by motor the second workbench and collet rotate;
Y-axis leading screw is set on X-axis leading screw, Y-axis leading screw arranges toolsmith's station;3rd motor-driven knife workbench moves back and forth along X-axis leading screw in X-direction, and the 4th motor-driven knife workbench moves back and forth along Y-axis leading screw in Y direction.
Preferably, described second workbench is slidably arranged on X-axis leading screw, and the first motor and the second motor do coaxial, movement at the uniform velocity.
Compared with prior art, the method have the advantages that
nullFirst,Double main shafts synchronize lathe,It is constituted: include cabinet base,Lathe bed,Also include the first workbench and the second workbench supported by lathe bed,The first motor fixed by lathe bed、Second motor、3rd motor、4th motor,First motor drive connection the first workbench,Second motor drive connection the second workbench,On first workbench, three-jaw self-centering chuck is set,Second workbench arranges collet,Second workbench can slide on leading screw,3rd motor-driven knife workbench moves back and forth along leading screw in X-direction,4th motor-driven knife workbench moves back and forth along leading screw in Y direction,First motor coordinates the second motor clamping thin and long units to do coaxially,Movement at the uniform velocity,Second workbench clamping thin and long units slides on leading screw,Strengthen the rigidity of thin and long units in processing,3rd motor and the 4th motor coordinate toolsmith's station along guide screw movement,It is processed.
The thin and long units work in-process of the second, the first motor-driven first workbench and the second motor-driven second workbench clamping can keep axiality, and movement at the uniform velocity, the second workbench can slide on leading screw, strengthens the rigidity in the thin and long units course of processing.Coordinate four motors to add to avoid the occurrence of man-hour in cutter relieving and the course of processing amount of deflection occurs carrying out thin and long units, prevent the phenomenons such as vibration.
3rd, the error of processing thin and long units is preferably minimized by the present invention, not only increases the efficiency of processing, and reduces processing cost, and low for rigidity, the processing of the part of size length is more accurate.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of the embodiment of the present invention 1;
Fig. 2 is the overall structure schematic diagram of the embodiment of the present invention 1;
Wherein: cabinet base 1, lathe bed 2, second workbench the 3, second motor 4, collet 5, thin and long units 6, X-axis leading screw 7, toolsmith's station 8, Y-axis leading screw 9, three-jaw self-centering chuck the 10, first motor the 11, first workbench the 12, the 3rd motor the 13, the 4th motor 14.
Detailed description of the invention
The technical scheme of invention below in conjunction with the accompanying drawings and is further illustrated by detailed description of the invention:
As shown in Figure 1, 2, double main shafts synchronize lathe, and it is constituted: includes cabinet base 1, lathe bed 2, also includes the first workbench 11 and the second workbench 3 supported by lathe bed.
First motor the 11, second motor the 4, the 3rd motor the 13, the 4th motor 14 fixed by lathe bed.First motor 11 drive connection the first workbench 12.Second motor 4 drive connection the second workbench 3.On first workbench 12, three-jaw self-centering chuck 10 is set.Second workbench 3 arranges collet 5, and the second workbench can slide on X-axis leading screw 7.
3rd motor 13 drives toolsmith's station 8 to move back and forth along X-axis leading screw 7 in X-direction, and the 4th motor 14 drives toolsmith's station 8 to move back and forth in Y-axis leading screw 9 direction.
First motor 11 coordinates the second motor 4 to clamp thin and long units 6 to do coaxially, movement at the uniform velocity, and meanwhile the second workbench 4 clamps thin and long units 6 and can slide on X-axis leading screw 7, it is therefore an objective to strengthen the rigidity of thin and long units 6 in processing.
3rd motor 13 and the 4th motor 14 coordinate toolsmith's station 8 to move along X-axis leading screw 7 and Y-axis leading screw 9, are processed thin and long units 6.
By the enforcement of the present invention, strengthen its rigidity when processing thin and long units 6, it is achieved rotate coaxially, it is to avoid amount of deflection occurs in thin and long units processing, cutter relieving occurs, prevent from processing occurs vibration, keep axiality.
In actual mechanical process, thin and long units one end is clamped on the three-jaw centering chuck of the first workbench, the other end is clamped on the collet of the second workbench, simultaneously drive the first and second motors, keeping coaxial, movement at the uniform velocity, the second workbench can slide on leading screw, clamping tension thin and long units, the 3rd motor, the 4th motor, two motor cooperatings is driven to drive toolsmith's station that thin and long units is processed.
In actual mechanical process, the first motor control mode ibid, the torque of the first motor is exported, is input in slave motor driver, the second motor uses direct torque mode, and its torque is consistent with the output torque of first motor.By the physical constraint between the first motor and the second motor load so that both rotating speeds and corner synchronize.Can avoid being affected by two motor transmission system machine errors when using which.
The above is only the preferred embodiment of the present invention, and protection scope of the present invention is not limited merely to above-described embodiment, and all technical schemes belonged under thinking of the present invention belong to protection scope of the present invention.It should be pointed out that, for those skilled in the art, some improvements and modifications without departing from the principles of the present invention, these improvements and modifications also should be regarded as protection scope of the present invention.
