Description
Technical field
The utility model relates to a kind of machine tool component, and in particular, it relates to a kind of lathe chuck.
Background technology
Lathe is that the lathe tool of doing feed motion carries out the lathe of machining to making the workpiece of rotation main motion.Lathe process principle is arranged on cutter and workpiece on lathe exactly, and by the transmission of lathe and the relative motion of speed change system generation cutter and workpiece, cutting movement, cuts the part meeting the requirements.
The general fixture adopting of lathe processing is scroll chuck, as shown in Figure 1, and spanner rotating cone gear for scroll chuck, bevel gear drives planar rectangular screw thread, then drives the centripetal motion of three-jaw, because the pitch of planar rectangular screw thread equates, so three-jaw move distance equates, has self centering effect.Scroll chuck is comprised of a bevel gear wheel, three bevel pinions, three claws.Three conelet teeth and bevel gear wheel engagement, there is flat thread structure at the back side of bevel gear wheel, and three claw deciles are arranged on flat thread.When pulling bevel pinion with spanner, bevel gear wheel just rotates, the flat thread at its back side just make three claws simultaneously to center near or exit.
Mobile three claws form the installing hole for clamping workpiece, and during work, workpiece is fixedly mounted in installing hole, rotate scroll chuck, and tool feeding, carries out machining to workpiece.When the longer workpiece of processing length, due to the gravity of workpiece self, workpiece easily upwarps near chuck one end, and the footpath of installing hole is deeply certain, the contact-making surface of scroll chuck clamping workpiece is fixed, scroll chuck is certain to the holding power of workpiece, and contact area is fixed, and the frictional force of workpiece and scroll chuck is certain, make workpiece that play easily occur, cause processed workpiece coaxiality deviation large, even cause workpiece distortion, therefore have much room for improvement.
Utility model content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of lathe chuck, and this lathe chuck makes the holding power that workpiece is subject to balance each other with the gravity of workpiece self, and workpiece is difficult for occurring play, guarantees the axiality that workpiece is processed.
For achieving the above object, the utility model provides following technical scheme: a kind of lathe chuck, comprise body, described body comprises chuck body and is arranged on the some claws on chuck body, each described claw surrounds the placement hole for clamping workpiece, described claw comprise First and with coaxial second of arranging of First, described First is fixedly installed on chuck body, between described First and second, be connected with adjusting portion, described adjusting portion is fixedly installed on second above and is located on First, described First is provided with the fixture that control and regulation portion moves.
By adopting technique scheme, the uniform ring of claw is located on chuck body, each claw surrounds the placement hole for clamping workpiece, claw comprises First and second, First is fixedly installed on chuck body, and First placement hole one side relative to second is diapire, and two diapires are in same plane, while making surface of the work clamping, in same plane, avoid workpiece run-off the straight; Between First and second, be connected with adjusting portion, adjusting portion is set on First and with second and is fixedly connected with, and by pulling second, due to second, is fixedly connected with adjusting portion, and adjusting portion is moved on First, thereby changes the length of claw.When needing the longer workpiece of clamping, clamping workpiece is entered in placement hole, the length that regulates claw, finally regulates fixture, and adjusting portion can not be moved, the contact area of workpiece and claw is increased, the holding power that workpiece is subject to increases relatively, thereby the frictional force that workpiece is subject to is also increased, and the gravity of the holding power that workpiece is subject to and workpiece self balances each other, workpiece is difficult for occurring play, guarantees the axiality of workpiece processing.
The utility model is further set to: between described First and second, be also provided with clip, described hoop sleeve is located in adjusting portion.
By adopting technique scheme, between First and second, by adjusting portion, connect, when the workpiece of clamping chuck more in short-term, by second, push First to, because adjusting portion is located on First, make adjusting portion indentation First, the axial length of claw shortens; While in like manner needing the longer workpiece of clamping; by second release; adjusting portion is pulled out in First; the length of claw is elongated; the contact area of workpiece and claw is increased; the hoop sleeve being provided with between First and second is located in adjusting portion; clip can be protected adjusting portion; simultaneously; clip can directly contact with outer surface of workpiece; the contact area of claw and workpiece is increased, thereby frictional force between claw and workpiece is increased, makes claw be difficult for occurring play, guarantee workpiece axiality.
The utility model is further set to: described clip comprises fixed part and the rotation section hinged with fixed part, and described rotation section is provided with latch, and described fixed part is provided with latch and patches the jack being connected.
By adopting technique scheme, clip treasure-house fixed part and the rotation section hinged with fixed part, the jack that the latch that rotation section is provided with is provided with fixed part patches and is connected, and after stretching claw, latch is separated with jack, fixed part cover is tapped into adjusting portion, regulate adjusting portion and fixed part, make First and second 's inwall and fixed part in same plane, make workpiece and clip laminating, finally latch is patched and is connected with jack, clip is fixed and is placed in adjusting portion.By latch, patch and be connected with jack, clip is firmly set in to adjusting portion and fits with workpiece, increase the frictional force of workpiece and claw, make workpiece be difficult for occurring play, guarantee the axiality of workpiece to be machined.
The utility model is further set to: on described First and second, be equipped with anti-slip veins.
By adopting technique scheme, on First and second, be equipped with anti-slip veins, the frictional force between claw and workpiece is increased, make workpiece be difficult for occurring axially or play longitudinally, further guarantee the axiality of workpiece.
The utility model is further set to: described fixture is bolt, and described First is provided with through hole, and described fixture is threaded with adjusting portion through through hole.
By adopting technique scheme, unscrew fixture, fixture is not connected with adjusting portion, adjusting portion can be again second upper mobile, thereby the distance between change First and second changes the length of claw.Claw is fixedly installed on chuck body, and claw long-term work wearing and tearing are large, by unscrewing fixture, adjusting portion and first from, because adjusting portion is fixedly connected with second, so second can be safeguarded separately, convenient claw is safeguarded.
