The utility model is characterized in that the damping shock absorption mechanism absorbs the shock caused by the running workpiece, which makes the shock caused by the running of the workpiece during the milling machine processing smaller, the running of machine tool more stable and the precision of the workpiece processing higher, thereby the production efficiency is increased further and the processing precision of the workpiece is guaranteed further.
Description
Technical field
The utility model relates to part, parts or the annex of lathe, is meant a kind of milling machine spindle transmission damping shock absorption mechanism especially.
Background technology
The existing machining tool that is used for the special spiral rod in fields such as plastics, oil adopts the kind of drive of ordinary gear transmission usually, because the special spiral rod workpiece is long, diameter is big, helical pitch is big, in Milling Processes, require the milling machine spindle slow-speed of revolution, large torque, therefore ordinary gear transmission lathe is when processing profiled screw rod, be difficult to reach preferably and very easily produce vibrations in processing effect and the process, thereby traditional special spiral rod processing mode more and more can not satisfy the needs of production development.
Summary of the invention
Technical problem to be solved in the utility model just is to overcome that workpiece moves jiggly defective in the process that existing special spiral rod Milling Process mode exists, and a kind of milling machine spindle transmission damping shock absorption mechanism that adopts the damping shock absorption structure is provided.Milling machine spindle transmission damping shock absorption of the present utility model mechanism is made of nut 1, damping wheel 2, main shaft 3, worm gear 4, worm screw 5, nut 6, the damping strap of the brake 7, transition block 8, bolt 9 and damping spring 10, damping wheel 2 and worm gear 4 are installed on the main shaft 3 successively, nut 1 and nut 6 be relative to lay respectively on the main shaft of damping wheel 2 and worm gear 4 outer ends, worm screw 5 is joined with worm gear 4 engagements, the damping strap of the brake 7 is enclosed within on the damping wheel 2 and connects transition block 8 and damping spring 10, by bolt 9 the damping strap of the brake 7 is connected on the tank wall.500 millimeters, wide 45 millimeters, high 5 millimeters of the damping strap of the brake 7 length; 60 millimeters, wide 45 millimeters, high 20 millimeters of transition block 8 length; Damping spring 10 specifications are LII18 * 2 * 32mm, should meet GB1239-89 (2) standard.When damping shock absorption mechanism is installed, for the accurate fixedly relative position of worm gear 4 on main shaft 3, can regulate, so that worm gear 4 reaches the best fit state with worm screw 5 by nut 1, nut 6; Worm gear, worm gear pair are for disappearing crack high accuracy worm couple, two helical pitch schemes about worm screw 5 is adopted, transverse tooth thickness vertically every millimeter thicken 0.02 millimeter, whole worm screw and thicken total amount and can reach 2 millimeters, by the fit clearance of adjusting worm gear and worm screw that moves axially of worm screw.When the milling machine working-spindle rotated, damping wheel 2 effect that 8 pairs of the damping strap of the brake 7 and transition block are contained on the main shaft 3 produced dampings, absorbs the vibrations that workpiece produces with damping spring 10 simultaneously, make milling machine more even running finish workpiece processing work.The damping size that produces between the damping strap of the brake 7 and the damping wheel 2 can be regulated by bolt 9 stretching damping springs 10.
Advantage of the present utility model just is that the milling machine spindle running part adds damping shock absorption mechanism, because damping shock absorption mechanism absorbs the vibrations that turning of work piece produces, and adopt by the two ends double nut and regulate the scheme that the worm and gear axial location is determined best fit gap and the two helical pitch worm couples of employing, make that milling machine adds that the vibrations that man-hour, workpiece rotate to produce are littler, the lathe operation more steadily, the workpiece machining accuracy is higher, thereby further improved the machining accuracy that production efficiency has also further guaranteed workpiece simultaneously.Thereby milling machine spindle transmission damping shock absorption of the present utility model mechanism has broad prospect for its application.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further;
Fig. 1 is that the master of the utility model milling machine spindle transmission damping shock absorption mechanism looks schematic diagram;
Fig. 2 is the schematic side view at the utility model spindle drive damping shock absorption mechanism damping wheel position.
See figures.1.and.2, the utility model milling machine spindle drive damping mechanism by nut 1, Damping wheel 2, main shaft 3, worm gear 4, worm screw 5, nut 6, the damping strap of the brake 7, transition block 8, bolt 9 and damping spring 10 consist of. Such as Fig. 2, transition block 8 and damping spring 10 chains are at the damping strap of the brake 7 On, regulate the capable of regulating damping strap of the brake 7 and damping wheel 2 by the 9 pairs of damping strap of the brake 7 degrees of tightness of bolt The damping size that produces.
The specific embodiment
Below be embodiment of the present utility model, the actual use of the present utility model is not limited to embodiment.
Adopt the milling machine spindle transmission damping shock absorption mechanism of the utility model structure to be applied on the three guide rail special spiral rod milling machines, processing plastic extruder diameter phi 210mm screw rod.Three guide rail special spiral rod milling machines adopt milling machine spindle transmission damping shock absorption mechanism, constitute by nut 1, damping wheel 2, main shaft 3, worm gear 4, worm screw 5, nut 6, the damping strap of the brake 7, transition block 8, bolt 9 and damping spring 10, damping wheel 2 and worm gear 4 are installed on the main shaft 3 successively, nut 1 and nut 6 be relative to lay respectively on the main shaft of damping wheel 2 and worm gear 4 outer ends, worm screw 5 is joined with worm gear 4 engagements, the damping strap of the brake 7 is enclosed within on the damping wheel 2 and connects transition block 8 and damping spring 10, by bolt 9 the damping strap of the brake 7 is connected on the tank wall.When damping shock absorption mechanism is installed, make worm gear 4 and worm screw 5 reach best fit with nut 6 by regulating nut 1; Worm gear, worm gear pair be for can disappearing crack high accuracy worm couple, worm screw 5 be about two helical pitches, transverse tooth thickness thickens 0.02 millimeter for every millimeter, by the fit clearance of adjusting worm gear and worm screw that moves axially of worm screw.When the milling machine working-spindle rotated, damping wheel 2 effect that 8 pairs of the damping strap of the brake 7 and transition block are contained on the main shaft 3 produced dampings, absorbs the vibrations that workpiece produces with damping spring 10 simultaneously, make milling machine more even running finish workpiece processing work.The damping size that produces between the damping strap of the brake 7 and the damping wheel 2 is adjusted in adjusting by bolt 9.Compare with the milling machine that damping shock absorption mechanism was not installed in the past, the vibrations that workpiece produces in the processing screw rod process disappear substantially, and the workpiece machining accuracy improves.
