Accompanying drawing explanation
Fig. 1 connects the structural representation of beveling machine for bend pipe inverse bonding that present pre-ferred embodiments provides.
Fig. 2 is the structural representation that binding clasp that in Fig. 1, bend pipe inverse bonding connects beveling machine matches with claw structure.
Detailed description of the invention
Below in conjunction with embodiment, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, do not limit the present invention.
See also Fig. 1 and Fig. 2, bend pipe inverse bonding connects beveling machine and comprises lathe 9, at least one binding clasp 3, drive mechanism, cutter head 4, slide unit 7, guide sliding structure 12, at least one claw structure 10.In the present embodiment, binding clasp 3 is 2, and claw structure 10 is several.
Guide sliding structure 12 is fixed on one end of lathe 9, and slide unit 7 is arranged on guide sliding structure 12.Guide sliding structure 12 can be two slide rails be arranged in parallel, also can one-body molded boss on lathe 9.Slide unit 7 fills described drive mechanism, described drive mechanism is installed cutter head 4.Described drive mechanism can comprise motor 6 and reductor 5, and reductor 5 and motor 6 are in transmission connection, and reductor 5 are installed cutter head 4.Lathe 9 can be provided with the electric box 2 be all electrically connected with reductor 5, motor 6.Cutter head 4 can fill some steel blades 11, and in the present embodiment, the quantity of steel blade 11 is three, three steel blades 11 can be distributed on cutter head 4, and steel blade 11 is preferably high-speed steel blade, and high-speed steel is a kind of metal cutting tool material, it has more high strength than common iron, more high rigidity.
Binding clasp 3 is fixed on the other end of lathe 9, and binding clasp 3 comprises all in circular arc and concentric, the upper clamping element 31 with radius, lower clamping element 32.Upper clamping element 31, lower clamping element 32 can synthesize annular, and preferably employing two is semi-circular.One end of upper clamping element 31 and one end of lower clamping element 32 hinged, preferably, one end of upper clamping element 31 is hinged with one end of lower clamping element 32 by hinge 1.The other end of upper clamping element 31 and the other end of lower clamping element 32 are the handle mechanism that open type activity is locked.Particularly, by arrange eccentric handle 34 realize open type connecting rod add eccentric wheel locking.Described handle mechanism comprises eccentric handle 34, connecting rod 35, clamp 37, the other end articulated linkage 35 of lower clamping element 32, and the other end of connecting rod 35 is by the hinged eccentric handle 34 of clamp 37.When upper clamping element 31 is opened, described handle mechanism is only connected with lower clamping element 32 by connecting rod 35.During clamp operation, in upset, clamping element 31 covers on workpiece, makes the clamp 37 of described handle mechanism aim at clamping element 31 point-blank and push, and firmly rotates eccentric handle 34 with the other end hinge of connecting rod 35 for the center of circle and implements clamp operation.The most common clamping mode of one is screwed tight.This method efficiency comparison is low.Disclosed herein is a kind of clamping means efficiently.Lower clamping element is hinged a connecting rod, connecting rod other end chain connection eccentric handle.When binding clasp is opened, this handle mechanism is only connected with lower binding clasp.Clamp operation: in upset, clamping element covers on workpiece, adept handle mechanism point-blank pushes the clamp of upper clamping element, firmly with the other end hinge of connecting rod for clamp operation implemented by center of circle turning handle.The part that this eccentric handle contacts with the clamp of upper clamping element is actual is a cam.The locking profile of cam will meet self-locking requirement.So the clamping stroke of cam little, for different tube diameters pipe we with different claws.The process of rotating this cam is exactly to the process of workpiece pressurization clamping.Design eccentric handle can improve operating efficiency greatly.
Claw structure 10 can be divided into two lobes or a few lobe, the interior of claw may be used for through difference the pipe (i.e. workpiece) clamping different tube diameters, binding clasp 3 applies clamping force by claw to workpiece, use claw can reduce the complexity of binding clasp, can handled easily, the pipe for the identical caliber of processing has a small lot effect particularly evident.In the present embodiment, claw structure 10 comprises all in circular arc and concentric, the upper clipping claw 13 with radius, lower claw 14, on the detachable inner side being arranged on clamping element 31 of upper clipping claw 13, on the detachable inner side being arranged on lower clamping element 32 of lower claw 14.The radius of upper clipping claw 13, lower claw 14 is less than the radius of clamping element 31, lower clamping element 32.Claw structure 10 also can be more for subsequent use on lathe 9 on binding clasp 3 except being arranged on.
Slide unit 7 is fixed with a cam handle 8, described bend pipe inverse bonding connects beveling machine and also comprises spring 16, and one end of spring 16 is fixed on slide unit 7, and one end of spring 16 is fixed on slide unit 7 and is fixed on lathe 9, when spring 16 resets, slide unit 7 can be made to be positioned at the end of lathe 9.Cam handle 8 promotes slide unit 7 feeding processing, utilizes spring 16 to reset.
In sum, the present invention is the special purpose machine tool of an independent operating.The headstock of lathe 9 has two quick clamp devices 3, and during length license, with two binding clasp 3 clamping work pieces 1, length uses a binding clasp 3 very in short-term.The replaceable clamping jaw structure 10 of workpiece 1 of processing different tube diameters.Binding clasp 3 be two semi-circular, join the semi-circular gripping dogs of different tube diameters; The side of binding clasp 3 is fixed hinges, and opposite side is that open type connecting rod adds eccentric wheel locking (see Fig. 2).Lathe 9 other end dress slide unit 7, slide unit 7 fills motor 6 and reductor 5, and dress cutter head 4, cutter head 4 fills three high-speed steel blades 11, and blade 11 can very convenient dismounting and change sharpening.Promote slide unit 7 with cam handle 8 to move, carry out machining, hand pine spring 15 drives slide unit 7 to reset.
The present invention apply time, relate to following some:
1, clamping: binding clasp 3 li installs the claw up and down adapted with caliber, open binding clasp 3, the enough long card of pipe two binding clasps 3, a short just card binding clasp 3, bend pipe along machine direction while be close to lathe 9 or ground or other assistive device, push-tight binding clasp 3 (eccentric clamping);
2, process: starter motor 6, hand rotation cam handle 8 promotes slide unit 7 feeding processing.Iron filings case stops, observe groove width enough time to loose one's grip withdrawing;
3, workpiece 1 is changed.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
