Abstract
The present utility model relates to an automatic fast three-claw clamping apparatus and belongs to the field of clamping technology. Said device have three claws is improved in that said three-claw is a curve block which has a polar radius gradual change curve outline in its side and has rotary shafts supported parallelly in a turbine box respectively, wherein said rotary shafts are equipped with coaxial pinions meshing with same inner gear each, said inner gears are supported rotatablely in a turbine box and are connected to the turbine with same shafts, and said turbine meshes with a worm gear driven by a rotary power source. Because the present utility model replaces the progress driven by the three-claw spiral transmission with the olar radius gradual change when the curve blocks rotate, the clamping velocity is greatly increased; because the conventional three-claw centering clamping is replaced by that of cam-clamping-principle-like, the device in accordance with the present utility model adapt to clamp samples with a variety of shapes and is capable of satisfying some special requirements of sample processing in a lab.
Description
Technical field
The utility model relates to a kind of clamping device of machining workpiece, and especially a kind of three-jaw clamping device of clamping work pieces fast that is applicable to automatically belongs to the clamp technology field.
Background technology
The laboratory need be satisfied at short notice with machining equipment and rapidly metallurgical sample carried out machining requirements, thereby is convenient in time carry out the metallographic assay.For this reason, require the clamping of finishing that the sample clamping device can be safe rapidly to operate.The conventional brace of existing scroll chuck, clamp and so on obviously can't satisfy above-mentioned requirements.
Retrieval is found, the applying date is that the Chinese patent application that July 14, application number in 1993 are CN93108714.7 discloses a kind of " multifunction fast actuating device for three-jaw chuck ", this device is under the prerequisite that does not change common three-jaw self-centering chuck structure, use a kind of with chuck rotation tooth bar one gear type switching mechanism and be fixed in the lever driving mechanism of lathe stationary part, individual components form with standard, with lathe and chuck combination, can not clamp under the dead ship condition.The applying date is that 1999.01.14, application number are that the disclosed device of Chinese patent application that CN99230769.4, name are called " multifunction fast actuating device for three-jaw chuck " is fixed in the static position of lathe with the lever driving mechanism, lantern ring type switching mechanism is enclosed within the chuck shell and rotates with chuck, the operator does not touch chuck, not shut-down operation.Chuck structure is constant, gripping range can be in the former scope of chuck rapid adjustment.These are to the improvement of traditional scroll chuck, fast automatic clamping for lathe workpiece has progressive meaning, but for metallurgical sample Milling Process, owing to do not change the worm drive structure of traditional three-jaw self-centering chuck, therefore clamp speeds is still rapid inadequately, and can't reliably clamping irregular contour workpiece, still be difficult to satisfy instructions for use.
The utility model content
The purpose of this utility model is: at the shortcoming that above prior art exists, proposes a kind of automatic three-paw quick clamping device that can quick safe clamping irregular contour workpiece, thereby satisfy the specific demand that laboratory sample is processed.
In order to reach above purpose, automatic three-paw quick clamping device of the present utility model comprises three-jaw, its improvements are that described three-jaw is the curve piece that the side is shaped on utmost point footpath gradient ramp profile, the rotating shaft of described curve piece is parallel respectively to be supported in the worm gear case, be fixed with coaxial pinion in the described rotating shaft respectively, described each pinion and the engagement of same internal gear, described internal gear is rotatable to be supported in the worm gear case, fixedly connected the worm engaging that described worm gear and rotating power source drive with worm gear is coaxial.
Like this, when worm gear rotates under worm screw drives, will drive three pinions by internal gear and rotate synchronously, the result makes the curve piece that forms the three-jaw clamping structure dwindle interior zone fast, by the effect of curved profile, fast with automatic safe the clamping of the sample of different shape.Because directly changing, the utmost point when the utility model rotates with the curve piece replaces the progressive of transmission three-jaw worm drive, therefore clamp speeds significantly improves, simultaneously owing to replaced traditional three-jaw centering clamping with the principle that is similar to the cam clamping, therefore be fit to the sample of clamping different shape, thereby satisfy the specific demand of laboratory sample processing.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the structural representation of an embodiment of the utility model.
The specific embodiment
The automatic three-paw quick clamping device of present embodiment as shown in Figure 1, three-jaw essence is that center of rotation is distributed on three curve pieces 4 on the same circumference, the side of each curve piece is shaped on the involute curve profile, forms the three-jaw clamping structure around the worm gear axle center.The rotating shaft 5 of curve piece is parallel to each other, by metal (upper 11 vertical support on worm gear case 3.Rotating shaft 5 middle parts be fixed with 6, three pinions of coaxial pinion simultaneously with inner gear housing 12 on the internal gear engagement.Inner gear housing 12 is supported in the worm gear case by ball is rotatable, with worm gear 13 coaxial fixedlying connected.Worm gear 13 meshes with the worm screw 14 that air motor drives.Whole worm gear case is installed on the spherical guide 1 of quick milling machine by ball wire bar pair 2.
When air motor rotates, will drive internal gear rotation by worm-gears, and then drive three pinions and rotate synchronously, realize that three curve pieces directly change the quick clamping (or unclamping) of formation by the curved profile utmost point.The clamping of curve piece makes that not only clamping is very rapid, and contacts with having certain thickness clamped one-tenth line, therefore is suitable for the clamping of different shape sample.The clamping device clamping that experiment showed, present embodiment is safe, and air motor can keep clamping force, can satisfy the needs of Milling Process well.
In addition, stingy cylinder 9 upwards is equipped with in the worm gear center of worm gear case 3, and the expansion link upper end of stingy cylinder 9 is fixed with push rod 8, therefore can sample be located as required up and down by cylinder, further facilitates clamping, guarantees to clamp effect.
In order to adapt to the clamping of the thicker sample of thickness, the mobile cover 7 that can stretch up and down is equipped with at the upper surface worker platform middle part of worm gear case 3, the lower surface that moves cover 7 is resisted against on the spring 10, and upper surface is spacing by worm gear case upper surface worker platform, and push rod 8 passes the centre bore that moves cover 7 and protrudes upward.Like this, when the user needs the sample of milling thicker (for example thickness is 60mm), can press down from sample upper surface (usually by milling machine upper cylinder implement), together with push rod 8 and move cover 7 and sink under worker's platform, thereby make the three-jaw can be by the desired height clamping test pieces.After finishing processing, under the effect of spring 10, move cover 7 from horizontal reset, concordant with worm gear case upper surface worker platform.
The automatic three-paw quick clamping device design of present embodiment is ingenious, perfect, compact conformation, and the various profile sample of clamping workpiece realizes that workpiece switches fast in brill, miller position, can satisfy the specific demand of laboratory sample processing well rapidly.
In addition to the implementation, the utility model can also have other embodiments.For example, the profile of curve piece can adopt helix, conic section etc., and rotating power source also can adopt motor etc.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
