Description

Thin-wall pipe Excircle machining fixture
Technical field
The invention belongs to field of machining, be specifically related to a kind of thin-wall pipe Excircle machining fixture.
Background technology
At present, in automation equipment production process, usually can use thin-wall pipe, and in order to make thin-wall pipe coordinate with other parts in equipment better, usually need to process the cylindrical of thin-wall pipe.Thin-wall pipe add man-hour requirement first with clamping device by thin-wall pipe clamping position, the clamping device normally scroll chuck of current processing thin-walled pipe fitting, thin-wall pipe clamps from the outer wall of thin-wall pipe by the jaw adding scroll chuck in man-hour, but, because the tube wall of thin-wall pipe is thinner, easily cause the tube wall of the thin-wall pipe of hollow broken when thin-wall pipe clamps by scroll chuck, defect rate is high, and waste is large; In addition, because scroll chuck is clamped by pipe fitting from the outer wall of thin-wall pipe, thus scroll chuck can shelter from the outer wall of thin-wall pipe, make cutter to thin-wall pipe outer wall add man-hour can not time processing complete, and need to carry out the processing that secondary clamping just can complete whole thin-wall pipe after thin-wall pipe dismounting, troublesome poeration, efficiency is low.
Summary of the invention
The technical problem to be solved in the present invention easily damages the outer wall of thin-wall pipe for existing thin-wall pipe clamping device and thin-wall pipe can not be made once to complete the technological deficiency of processing, provides a kind of outer wall of not fragile thin-wall pipe and thin-wall pipe can be made once to complete the thin-wall pipe Excircle machining fixture of processing.
In order to solve the problems of the technologies described above, the invention provides following technical scheme: thin-wall pipe Excircle machining fixture, comprises mandrel, chuck and top cover, the end of mandrel is provided with bigger diameter end elasticity conehead outwardly; Described chuck is sheathed on mandrel, the circular hole and taper hole that communicate is provided with in chuck, circular-hole internal-wall contacts with mandrel side, taper hole inwall and elasticity conehead contacts side surfaces, the outer wall of chuck is provided with projection, the outer wall of chuck is positioned at protruding inner side and is also arranged with expansion sleeve, be provided with one group of pressurization hole in chuck, the end in one group of pressurization hole all contacts with expansion sleeve; Described top cover is sheathed on inner side mandrel being positioned at chuck, the endoporus inwall of top cover and the contacts side surfaces of mandrel, the outer wall of top cover is provided with two cylinders, the center line of two cylinders is located on the same line, the bottom of two cylinders is equipped with spring, the end of spring is provided with fore-set, and top cover is also provided with the locking nut for locking mandrel away from the end of chuck.
Adopt the thin-wall pipe Excircle machining fixture of technical solution of the present invention, comprise mandrel, the end of mandrel is provided with bigger diameter end elasticity conehead outwardly, and mandrel plays a support, and mandrel can drive elasticity conehead to move inward, thus the elastic cone crown is made to grip cover, also comprise chuck, chuck is sheathed on mandrel, chuck is for clamping thin-wall pipes, the circular hole and taper hole that communicate is provided with in chuck, circular-hole internal-wall contacts with mandrel side, thus mandrel can slide in circular hole, and chuck is when being subject to footpath outward force, mandrel also can give chuck and support, taper hole inwall and elasticity conehead contacts side surfaces, thus elasticity conehead can slide in taper hole, and moving inward of elasticity conehead can drive chuck to move inward, thus thin-wall pipe is clamped by chuck, the outer wall of chuck is provided with projection, end that is protruding and thin-wall pipe offsets, avoid thin-wall pipe outwards movement, the outer wall of chuck is positioned at protruding inner side and is also arranged with expansion sleeve, thin-wall pipe is sheathed on expansion sleeve, the external diameter of expansion sleeve is less than the internal diameter being slightly less than thin-wall pipe, one group of pressurization hole is provided with in chuck, the end in one group of pressurization hole all contacts with expansion sleeve, can exert pressure to expansion sleeve in one group of pressurization hole, in one group of pressurization hole, gases at high pressure are filled with during enforcement, described gases at high pressure give expansion sleeve one outside pressure, thus thin-wall pipe is held out against, and the sidewall of thin-wall pipe can also be made to obtain a support, the sidewall of thin-wall pipe is avoided to add man-hour stressed and damage, described top cover is sheathed on inner side mandrel being positioned at chuck, top cover is used for being clamped by thin-wall pipe from one end away from chuck of thin-wall pipe, the endoporus inwall of top cover and the contacts side surfaces of mandrel, thus mandrel can slide in the endoporus of top cover, and mandrel also can give top cover support, avoid top cover generation radial displacement, the outer wall of top cover is provided with two cylinders, the bottom of two cylinders is equipped with spring, the bottom of spring is provided with fore-set, spring can make fore-set move in cylinder, fore-set and thin-wall pipe offset away from one end of chuck, thus realize thin-wall pipe to hold out against, axial location is carried out to thin-wall pipe.
Technique effect of the present invention is: because thin-wall pipe is sheathed on expansion sleeve, thin-wall pipe holds out against from the inwall of thin-wall pipe by expansion sleeve, carry out radial location to it, and while location, expansion sleeve can give thin-wall pipe from the inwall of thin-wall pipe and support, and avoids scroll chuck and thin-wall pipe clamping is damaged by thin-wall pipe from the outer wall of hollow thin-wall pipe; Thin-wall pipe clamps, carries out axial location to thin-wall pipe from the two ends of thin-wall pipe by fore-set and projection respectively; Because expansion sleeve, projection, fore-set do not shelter from the outer wall of thin-wall pipe when locating thin-wall pipe, thus thin-wall pipe can be made once to complete Excircle machining, avoid secondary clamping, simple to operate, efficiency is high.
Further, described spring contacts with cylinder inner wall, and described fore-set side contacts with cylinder inner wall.Thus fore-set and spring can be avoided to rock.
Further, the side near chuck on the side of described fore-set is provided with draw-in groove.Draw-in groove can to the further radial location of thin-wall pipe.
Further, cushion is provided with in described draw-in groove.Cushion strengthens the locating effect of draw-in groove, and the end of thin-wall pipe can be protected not to be damaged.
