Abstract
The utility model relates to a structural improvement on a three-jaw chuck of a lathe, which belongs to the technical field of jigs for machine tools. The jaw comprises a chuck body, and inner disc wire with an angular wheel disc on the end face is arranged inside the chuck body. The angular wheel disc is meshed with a linked angular wheel on the side face of the chuck body. Jaws capable of sliding are arranged in three clamping grooves on the front end face of the chuck body respectively. The wire teeth on the bottom surface of each jaw are meshed with the Archimedes spiral at the front of the inner disc wire. The utility model is characterized in that the bottom face of each jaw is made into a rack shape which is meshed with a pinion arranged among the clamping grooves. The other side of the pinion is meshed with a rack on the upper surface of the top jaw which forms a moving pair with the clamping groove, and the outward extending end is positioned at the position relative to the jaw. The utility model can effectively avoid the holding deformation for thin-wall workpieces, and has the advantages of simple structure and convenient operation.
Description
Technical field
The utility model relates to a kind of chuck of lathe, and especially a kind of architecture advances of lathe scroll chuck belongs to the jig technical field.
Background technology
Three-jaw self-centering chuck is mounted in the matched clamp of lathe spindle front end, its basic structure is for installing the interior parcel that the bottom surface is shaped on the bevel gear dish in chuck body, this bevel gear dish and the interlock bevel gear engagement that is installed in the chuck body side, in three road draw-in grooves of chuck body front end face, be equipped with respectively can slippage claw, the silk tooth of each claw bottom surface meshes with the Archimedes spiral of interior parcel front.Therefore, when the interlock bevel gear centre bore that spanner is inserted the chuck body side, and when ordering about it and rotating, the interlock bevel gear will drive the bevel gear dish, parcel rotation in making, and then synchronously entad or centrifugal mobile order about three claws, thus clamping work pieces.
Though scroll chuck has the self-centering function, clamp operation is convenient, can only the unidirectional application of force during every claw clamping, and therefore when the clamping thin-wall workpiece, cause workpiece deformation easily, thereby influence the workpiece turning quality.
In order to address the above problem, the Chinese invention patent application " two-stage driving self-centering double scroll chuck " that application number is 011031336, the applying date is February 26 calendar year 2001 discloses a kind of essence by inside and outside two groups of turning attachments that scroll chuck constitutes.Because therefore one group in twos of the claw of these anchor clamps can not cause distortion respectively by inside and outside both direction application of force clamping thin-wall workpiece, but its complex structure need to drive inside and outside claw respectively, so the clamping operation is cumbersome.
The utility model content
The purpose of this utility model is: the shortcoming that exists at above prior art, but a kind of simple in structure, clamping thin-wall workpiece scroll chuck that clamping is easy to operate is proposed.
In order to reach above purpose, the technical solution of the utility model is: but the scroll chuck of clamping thin-wall workpiece, comprise the interior parcel that the bottom surface is shaped on the bevel gear dish is installed in the described chuck body of chuck body, described bevel gear dish and the interlock bevel gear engagement that is installed in the chuck body side, be equipped with respectively in the three road draw-in grooves of described chuck body front end face can slippage claw, the Archimedes spiral engagement of the silk tooth of described each claw bottom surface and interior parcel front, its improvements are, spline-simulating is made in described claw bottom surface, and be installed in the pinion between the draw-in groove, the tooth bar engagement of the opposite side of described pinion and top pawl upper surface, described top pawl and described draw-in groove constitute moving sets, and overhanging end is in the position relative with claw.
The method of operating of the utility model clamping thin-wall workpiece is the same with common scroll chuck, when claw when draw-in groove moves in or out, the rack drives pinion rotation of bottom surface, and then, thereby claw and on the other side top pawl overhanging end between form inside and outside the active force of two-way clamping work mobile round about by the rack drives top pawl of opposite side.
Further improving of above technical scheme is on the overhanging end of described top pawl the adjusting bolt to be housed.So that according to the different wall of workpiece, regulate the spacing of top pawl and claw.
Obviously, the utility model can effectively be avoided the clamping distortion of thin-wall workpiece, and simple in structure, easy to operate.
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.
Fig. 2 is the right view of Fig. 1.
The specific embodiment
Embodiment one
But the scroll chuck of present embodiment clamping thin-wall workpiece as depicted in figs. 1 and 2, mainly is made up of chuck body 1, interlock bevel gear 2, interior parcel 3, top pawl 4, master jaw 5, pinion 6, claw 7, adjusting bolt 8.Wherein in the chuck body 1 the interior parcel 3 that the bottom surface is shaped on the bevel gear dish is installed, this bevel gear dish and interlock bevel gear 2 engagements that are installed in chuck body 1 side.The front end face of chuck body 1 is equipped with claw 8, claw 8 be placed in draw-in groove in can slippage master jaw 5 fixedly connected.The Archimedes spiral engagement of the silk tooth of master jaw 5 bottom surfaces and interior parcel 3 fronts.The draw-in groove place of chuck seat 1 is shaped on chimb B, is shaped on round on the chimb B, between pinion 6 is installed.Spline-simulating is made in outer end, claw 8 bottom surface, with pinion 6 engagements.The tooth bar engagement of the opposite side of pinion 6 and L shaped top pawl 4 tail end upper surfaces.Top pawl 4 also constitutes moving sets with draw-in groove, and overhanging end is in the position relative with claw 7, is equipped with on the overhanging end and regulates bolt 8.
During the clamping thin-wall workpiece, select to install pinion according to the workpiece external diameter earlier, mix up the adjusting bolt.Again as the operation common scroll chuck the switching spanner, when claw when draw-in groove moves inward, the rack drives pinion rotation of bottom surface, and then the rack drives top pawl that passes through opposite side is outwards mobile, thereby forms the active force of inside and outside two-way clamping work between the adjusting bolt of claw and relative with it top pawl overhanging end.Like this, not only can the reliable grip workpiece, and can effectively avoid the clamping distortion of thin-wall workpiece, it is simple in structure, and is easy to operate, applied widely.After removing top pawl and pinion, can use as common scroll chuck.
In addition to the implementation, the utility model can also have other embodiments, for example with relative position exchange of claw and top pawl 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.
