Description

Milling machine tool for groove of thread
The utility model relates to the improvement of a kind of helicla flute processing or crescent special equipment.
In machining, spiral fluted processing to degree of precision, for example, helicla flute on the gas engine piston, by milling machine or grinding machine processing, the feed motion of the circumferencial direction of its workpiece and axial feed motion are realized by workbench and special fixture thereof usually, and the feed cutter of its depth direction, feeding as milling head or bistrique is operated by hand, so dimensional accuracy is difficult to guarantee that work efficiency is also lower.
The purpose of this utility model is the characteristics of comprehensive milling machine and grinding machine, improves the delivering gear of former lathe vertical direction, makes its energy autofeed, withdrawing, has specialized production capacity, thereby can process helicla flute or crescent easily, increases work efficiency.
The purpose of this utility model realizes in the following manner.
Lathe described in the utility model, include base, lathe bed, have workbench, electric device and the delivering gear of special fixture, this delivering gear comprises that a plane motion that is made of handwheel, screw mandrel, the saddle that has guide rail and slide pays, the milling head or the bistrique of drive are installed on the saddle, its slide is fixedly connected on the bed piece, it is characterized in that: 1) be connected with gravity or elastic reset mechanism on the described saddle; 2) there is one to be used for the driven member roller that the cam gyration is paid on the described saddle, it and driving link feed cam constitute the plane cam gyration and pay, its feed cam is installed on the take-off (propeller) shaft of the reducing gear that has motor, it by motor through the reducing gear driven rotary.On the periphery of feed cam, be arranged with working curve section and withdrawing curved section, described working curve section is made of involute section or helical segment and all segmental arcs, the lift of involute or helix just in time equals to want the flute profile degree of depth of processing work, its withdrawing curved section is an arc section, 3) a switch control cam also is installed on the described reducing gear take-off (propeller) shaft, the projection of this control cam and the withdrawing curved section of feed cam are on same orientation, the travel switch of a control reduction box motor is installed on this protruding movement locus, when the control cam forwards boss to and presses current Cheng Kaiguan, then reduction box quits work, and feed cam stops operating.
Described gravity reduction mechanism, constitute by sprocket wheel, chain and the balancing weight that is attached thereto, sprocket shaft is fixed on the bed piece, chain one end is connected on the saddle after walking around sprocket wheel, the other end is connected on the balancing weight greater than the saddle component weight, makes this saddle remain an active force that makes progress, described elastic reset mechanism, promptly between saddle and lathe bed, connect a spring, make its elastic force upwards and greater than the gravity of saddle parts.
Be further described below by embodiment.
Fig. 1 is the utility model structural representation.Among the figure, (1) is base, establish regulator cubicle (18) and electric switch (2) in this base, (3) be the X-Y workbench, be equipped with the special fixture (4) that to realize that workpiece rotates on this table top, drive bistrique or milling head (5) are fixed on the saddle (6), slide (7) is packed on lathe bed (8) outside wall surface, be fixed with chain (11) on the support that saddle stretches out (9), this chain is walked around sprocket wheel (10) and is connected with balancing weight (17), on another support (16) that saddle stretches out, be provided with roller (15), this roller and feed cam (12) are meshed and constitute cam plane of rotation kinematic pair.Described feed cam (12) is installed on the take-off (propeller) shaft of reduction box (13), and reduction box provides power by motor (14).Be arranged with three sections working curves and three sections withdrawing curved sections on the periphery of this feed cam (12), the working curve section is made of involute section and arc section, when the involute section of feed cam is initial when meshing with roller, bistrique begins the feed cutting, when meshing point arrives the least significant end of involute, it is maximum that the depth of cut size of bistrique reaches, and promptly its degree of depth equals the lift of involute.After this, meshing point is wasted no longer feed of head, but is carried out tarry matter, with size and the surface smoothness of guaranteeing work at arc section.When cam is rotated further, when making meshing point arrive cam withdrawing curve arc section end,, simultaneously,, switch press current Cheng Kaiguan that motor is stopped operating because controlling cam because the effect of balancing weight makes the bistrique rapid return.This moment the operator lifting workpiece, as crawl console button again, feed cam rotates again and promptly enters the next work period, and three sections working curve sections are arranged on the cam, so a moving week of cam revolution, and three work periods can be arranged.
Fig. 2 is Fig. 1 right side TV structure schematic diagram.Wherein (10) are sprocket wheel, and sprocket shaft (22) two ends are packed in the lathe bed areole, are equipped with feed cam (12) on the output rotation axis (20) of reduction box (13), also are equipped with switch control cam (21).When cam (21) turns to projection when pressing current Cheng Kaiguan (19), electric wiring is disconnected, then reduction box quits work, feed cam stops operating, this moment under the gravity active force of balancing weight, bistrique automatic withdrawal, feed-disabling.
Fig. 3 is the structural representation of feed cam (12).Wherein (23) are the withdrawing curved section, and (24) are the working curve section, and wherein the lift h of involute section equals the degree of depth of workpiece flute profile.
Present embodiment can conveniently be processed helicla flute and crescent on the gas engine piston, and the feed cam revolution moves a week, can process three plunger slot.
In force, as using elastic reset mechanism, promptly remove sprocket wheel, chain and balancing weight, connect an extension spring between support (9) and lathe bed, its elastic force is greater than saddle weight partly.
Lathe described in the utility model, compact conformation, volume are little, easily manufactured, helicla flute or crescent on the processing gas engine piston, the efficient height, and can guarantee dimensional accuracy preferably.
