Description
Technical field
The invention relates to CNC milling machine, is specifically related to main spindle box.
Background technology
The structure of the spindle box part of CNC milling machine is that spindle motor drives the main shaft rotation by synchronous belt both at home and abroad, and knife striking cylinder is installed in the main shaft top to realize automatic tool changer.
The bel-drivenn advantage is that noise is little, low cost of manufacture, and it is also low to damage the cost of changing the back, but damage easily, maximum defective is that belt transmission can not provide very big moment of torsion, says exactly almost to increase moment of torsion, bigger if desired moment of torsion will increase power of motor.
And the spindle box part structural shape of main shaft and spindle motor direct connection is realized relatively difficulty of automatic tool changer, and design, installation requirement difficulty are higher.
Summary of the invention
The technical problem that the invention will solve is that the Heat stability is good of a kind of main shaft and spindle motor direct connection, the main spindle box of good processing accuracy are provided.
The scenario of the invention:
Spindle motor utilizes spline to be connected with main shaft and transmits moment of torsion, and project organization can move up and down to realize the loose broaching tool function of main shaft it.
The technical solution of the invention:
Replace knife striking cylinder with hydraulic control, use hydraulic control during loose cutter.Oil cylinder is oil circuit and gas circuit and uses particular design, main shaft pine cutter during the oil cylinder oil-feed, and gas circuit ventilation simultaneously is to realize the function of main shaft endoporus inflatable.The oil circuit oil return is simultaneously because the effect of the dish spring force of main shaft inside moves up pull bar, and cutter and handle of a knife tapering face are fitted and locking mutually, thereby for preventing oil cylinder because the gravity of self drives the loose cutter of pull bar downwards, the spy is provided with support spring.Concrete scheme is as follows:
Main spindle box is characterized in that, electric machine support 5 is fixedly mounted on the main spindle box 1, and motor plate 18 is fixed on the electric machine support 5, and spindle motor 19 is fixed on the motor plate 18, and 19 times direct connections of spindle motor have main shaft 12; Locking nut 15 is fixed on gland 14 on the main shaft 12, and gland 14 is fixed together with drive sleeve 11 and spline drive sleeve 13 and forms a shaft coupling, and an air admission hole 20 is arranged on the spline drive sleeve 13; Drive sleeve 11 is connected with spindle motor 19 usefulness keys, and spline drive sleeve 13 is connected with main shaft 12 usefulness splines; Shaft coupling can move up and down on main shaft 12 with what realize main shaft and send the broaching tool function, and transmits moment of torsion; Piston 10 is fixed on the motor plate 18, and cylinder body 16 and end cap 17 are formed an oil cylinder.In the oil cylinder during oil-feed, cylinder body 16 moves down applying spline drive sleeve 13 and drives shaft coupling and main shaft 12 moves down, main shaft pine cutter, and air admission hole 20 air inlets on the spline drive sleeve 13 simultaneously are to realize the air blowing function of main shaft; Photosignal switch 2 and optoelectronic switch 4 are contained on the electric machine support 5, and signal lever 3 is contained on the cylinder body 16, and photosignal switch 2 and optoelectronic switch 4 are contained in the below and the top of signal lever 3 respectively; When oil cylinder moves down, when being installed in signal lever 3 on the cylinder body 16 and running into photosignal switch 2, send signal, main shaft pine cutter is finished.
Screw 9 is fixed on the cylinder body 16, and screw 7 is fixed on the plate 6, and plate 6 is fixed on the electric machine support 5, spring 8 one ends at an end on the screw 7 on screw 9, electric machine support 5 maintains static, thereby gives the power of cylinder body 16 to make progress, when preventing the cylinder body main axis rotation since the gravity effect move down.
Operation principle: when main shaft stops the rotation, oil-feed in the cylinder body 16, oil cylinder moves down applying spline drive sleeve 13 and drives shaft coupling and moves down, main shaft pine cutter, air admission hole 20 air inlets simultaneously, main shaft is blown.When the signal lever 3 on being installed in cylinder body 16 is run into photosignal switch 2, send signal, main shaft pine cutter is finished.Carry out tool changing then, after tool changing is finished, lower part air inlet in the cylinder body 16, main spindle broach, cylinder body 16 moves up.Signal lever 3 on being installed in cylinder body 16 moves down when running into optoelectronic switch 4, sends signal, and main spindle broach is finished.Main shaft begins with certain rotating speed rotating machined workpiece.
The advantage of the invention:
Direct connection is the direct and motor coupling of main shaft, and advantage is the rotating speed that can provide higher, because saved transmission, does not have the heating in the transmission simultaneously, so Heat stability is good has also saved the loss of significance in the transmission simultaneously, can reach better machining accuracy.This kind of spindle box part structure of my company's design realizes automatic tool changer by the spindle unit hydraulic control simultaneously.
