Description of drawings
Fig. 1 is the utility model organigram;
Fig. 2 is that Fig. 1 centering and clamping mechanism A is to the 90 ° of figure that turn clockwise.
The specific embodiment
Describe the utility model specific embodiment in detail below in conjunction with accompanying drawing 1 and accompanying drawing 2:
1. the rotation of workpiece and axial feed motion
By first motor D1 through belt pulley, driving belt drives worm shaft 1 and rotates, through worm-gears 1,2 pass to power and are installed in the supercentral screw axis 3 of worm gear, the rotation of screw axis 3 drives the ball screw 4 that is assemblied in screw axis 3 left ends and rotates, so just formed rotatablely moving of screw axis 3, simultaneously at the right-hand member of screw axis 3 pneumatic the or hydraulically operated fixture 6 of high accuracy being housed rotates with screw axis 3 and moves axially, the rotary speed of screw axis 3 and feed speed, realize by first motor D1 of frequency converter adjustment rotating speed, so amount of feeding adjusting range is big and convenient.The utility model also is provided with automatic rewind down (F.F.) function of screw axis 3, even the rewind down of workpiece 7 (F.F.).When workpiece 7 wants rewind down (F.F.) preceding, clutch cylinder 14 drives clutch lever 15 withdrawal (release) clutches 16 and throws off, the 4th motor D4 running after belt pulley, driving belt be connected with safe shaft joint 17 1 ends on the Pulley shaft again, the other end of described breaking piece 17 is connected with gear shaft, gear 18 on the gear shaft is rotated, the rotation with the fastening ball nut 5 of gear 18 simultaneously converts moving axially of screw axis 3 to, but this just makes workpiece 7 rewind downs (F.F.) motion.
2. the clamping and positioning of workpiece
At first workpiece 7 right sides are placed on the following short sliding sleeve 9 of centering and clamping mechanism 8, driving leverages 12 by cylinder 13 then makes movable pressing board 11 on the positioning and clamping mechanism to lower swing, last short sliding sleeve 10 is installed on the movable pressing board 11, make short sliding sleeve 10, down short sliding sleeve 9 certain pretightning force is arranged is workpiece 7 and gap between the down short sliding sleeve 9,10 is zero with respect to workpiece 7, the left end of pneumatic by high accuracy again or hydraulically operated fixture 6 clamping work pieces 7 drives the pneumatic or hydraulically operated fixture 6 of high accuracy and workpiece 7 by screw axis 3 at last and rotates and move axially.Centering and clamping mechanism 8 is to utilize the outer round surface of workpiece 7 self-align, wherein short up and down 9,10 of the sliding sleeves of workpiece 7 ends limited workpiece 7 about, the moving of fore-and-aft direction, pneumatic or the hydraulically operated fixture 6 of the high accuracy of workpiece left end not only provides workpiece 7 motions required clamping force, also increase limited workpiece 7 about, the rotation of fore-and-aft direction.The centering precision of the pneumatic or hydraulically operated fixture 6 of high accuracy has guaranteed in 0.01 millimeter and during assembling that short 9 the axiality of overlapping of the downslide of its axis and centering and clamping mechanism 8 is in 0.015 millimeter, if the form and position tolerance of strict control workpiece 7 external diameters just can make workpiece 7 easy motion in short sleeve, for stabilized product quality is laid a good foundation.
The utility model centering and clamping mechanism 8 adopts short sleeves and do not adopt the purpose of major axis cover is in order to eliminate when the processing slim axle, reduce surface of the work and sliding sleeve because of rotating and move the friction that produces, make axis of workpiece produce bigger flexible deformation because of moment of torsion is excessive when eliminating the workpiece feed motion, thereby effectively guarantee the precision of the pitch, helix etc. of screw thread.Impracticable centering and clamping mechanism 8 then can be unfavorable for cutting because of the workpiece cantilever is oversize if only adopt the pneumatic or hydraulically operated fixture 6 of the high accuracy of left end, has had a strong impact on the tooth-face roughness, profile accuracy of workpiece etc.
3. the motion of cutter
The motion of cutter is made of two parts, and the one, make rotatablely moving that axle 20 obtains by second motor D2 through belt pulley, driving-belt, main shaft 20 drives cutterhead and cutter 19 mounted thereto and rotates together, the formation cutting movement.The 3rd motor D3 makes rotatablely moving that cutter drives ball screw 22 obtains by cutter drives motor shaft coupling 21, cutter drives ball screw 22 connects with the cutter drives ball nut 23 that is fixed on the slip crate, drives slip crates and moves up and down along guide rail and be used for controlling the processing dimension of workpiece 7 and the processing type of product by being installed in cutter drives ball nut 23 on the slip crate 24 again.
Cutter of the present utility model 19 is easy to loading and unloading, can rationally adjust the spiral arm length of cutter according to the product of different size, has improved the cutting rigidity of cutter greatly.Because centering and clamping mechanism 8 is adjustable with respect to the position of cutter 19, can rationally adjust the relative position of the sliding sleeve 9,10 on the centering and clamping mechanism according to the product of different size, so again because feed motion is to finish rigidity when having improved greatly also that workpiece is cut by rotatablely moving of workpiece.From above 2 as can be seen the utility model emphasis improved the machining condition of workpiece, thereby reduced the workpiece tooth-face roughness, the teeth groove profile error etc. of beating.Utilize the high rotating speed of cutter head structure and main shaft 20 to realize eccentric, micro-high-speed cutting, make the processing dimension once-forming of workpiece 7, improved operating efficiency greatly.Feed arrangement described in the utility model is made up of stepper motor D3, single chip microcomputer, cutter drives ball screw 22 guide rails etc.
