The whirling milling head is simple in structure, convenient in installation, stable in operation and high in processing efficiency.
Description
Technical field
The utility model relates to a kind of finish turning screw device, especially a kind of cyclone milling head of machining internal thread.
Background technology
At present, the screw thread of extensive use processing whirlwind mills, and is the high-speed milling device that cyclone milling head is installed on lathe carriage.Whirlwind mills generally by motor and drives belt pulley on the main shaft by motor pulley, connect knife bar and cutter successively, there is main shaft to rotate at a high speed, workpiece is carried out milling, machining screw, the entire work process that whirlwind mills has two motions synthetic, one is that lathe holding workpiece low speed rotation is finished the low speed feed motion, and its rotation is controlled about 10 commentaries on classics/min usually, and another is the high speed rotation of cutter head, finish cutting movement, its cutting speed can reach 2800-3200 commentaries on classics/min.Because the rotary speed height of cyclone milling head, and is connected with lathe, if contact strength is not high, can produces very big vibrations, cause stable very poorly, the accuracy of thread that processes can be too not high yet.
The utility model content
The technical problems to be solved in the utility model provides a kind of simple in structure, and is easy for installation, and the high cyclone milling head of working (machining) efficiency.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of cyclone milling head, it comprises drive system, bracing frame and milling attachment, described drive system comprises motor and is fixed in motor pulley on the motor output shaft, described milling attachment is connected by belt with described motor, it is characterized in that: support frame as described above comprises top board, pillar and base, described top board is a square plate, the structure of the cross section of base for falling " recessed " shape, be evenly equipped with bolt hole on its dual-side, top board is connected and fixed by being positioned at its root pillar and base of four jiaos; Described milling attachment comprises milling cutter, milling arbor, main spindle box and belt pulley, one distolateral wall of described milling arbor is provided with milling cutter, hollow shaft one end of its other end and described main spindle box is affixed, the described hollow shaft other end is connected with belt pulley, and described main spindle box is fixed in the upper surface of base by holder.
Described main spindle box inside is provided with four pairs of bearings.Four pairs of bearings are respectively angular contact ball bearing, thrust bearing, cylinder roller bearing and ball bearing, and the hollow shaft in these bearing fixing bearing housings is avoided axial play and vibration in process, it is operated steadily, and working (machining) efficiency and precision are provided.
Adopt the beneficial effect that technique scheme produced to be: 1, the utility model is simple in structure, makes easily; 2, base cooperates with supporting plate in the lathe, and is by the bolted on the lathe, easy for installation; 3, with bearing housing hollow spindle constraint milling arbor, make to add and eliminate vibration man-hour, improve working (machining) efficiency and precision.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a three-dimensional structure schematic diagram of the present utility model;
1, motor, 2, top board, 3, pillar, 4, milling cutter, 5 milling arbors, 6, protective cover, 7, belt, 8, main spindle box, 9, belt pulley, 10, holder, 11, base.
The specific embodiment
1 as can be known with reference to the accompanying drawings, the utility model is a kind of cyclone milling head, it comprises drive system, bracing frame and milling attachment, described drive system comprises motor 1 and is fixed in motor pulley on motor 1 output shaft, described milling attachment is connected by belt 7 with described motor 1 and it is characterized in that: support frame as described above comprises top board 2, pillar 3 and base 11, described top board 2 is a square plate, the structure of the cross section of base 11 for falling " recessed " shape, be evenly equipped with bolt hole on its two side, top board 2 is connected and fixed with base 11 by being positioned at its 4 pillars of four jiaos 3; Described milling attachment comprises milling cutter 4, milling arbor 5, main spindle box 8 and belt pulley 9, one distolateral wall of described milling arbor 5 is provided with milling cutter 4, hollow shaft one end of its other end and described main spindle box 8 is affixed, the described hollow shaft other end is connected with belt pulley 9, and described main spindle box 8 is fixed in the upper surface of base 11 by holder 10.Described main spindle box 8 inside are provided with four pairs of bearings.
The utility model is to drive the internal thread that belt 7 drives the milling attachment processing works by motor 1, and its motor pulley is provided with protective cover 6 outward, prevents from that belt 7 comes off in the process to meet accident.The utility model installation process is that this device is placed on the lathe supporting plate, the groove of base 11 is cooperated with middle supporting plate, the side of groove has the interior angle of inclination of 1.5-2 degree, passes base 11 sidewall bolts hole by bolt then and withstands the middle carriage both sides, makes it fastening; Process is that the workpiece of processing is fixed in the clamp mechanism (scroll chuck) of lathe, determine the workpiece velocity of rotation according to required pitch, be generally 8-12 commentaries on classics/min, start lathe then, start the motor 1 of cyclone milling head, finish the internal thread machining of workpiece.Shown in 1, the utility model can be processed a 2-6mm left side with reference to the accompanying drawings. dextrorotation triangle internal thread, and fine pitch trapezoidal internal thread, can also change milling cutter 4 as required, and satisfy the screw thread processing of other models; The utility model can cooperate C620-1 lathe or CA6140 lathe to use, and is extensively suitable to the processing of batch coarse pitch internal thread.
