Abstract
The invention relates to a clamping chuck for an automatic lathe. The clamping chuck is connected to the front part of a spindle of the automatic lathe through a flange; a flange sleeve with a conical opening is fixed at a flange opening; a pull rod and a chuck are connected in series and are arranged in a central hole of the flange; the front of the chuck is provided with a conical surface and is matched with the conical opening of the flange sleeve; an inner hole of the pull rod is in screw-thread fit with a positioning platform base; a peripheral surface of the front part of the positioning platform base is connected with a positioning platform and an ejection ring; a central hole of the positioning platform base is in clearance fit with a guide rod; the front of the guide rod is pressed against the rear side of the ejection ring; a spring is arranged between the guide rod and the positioning platform base; and a limiting nut is sleeved at the rear end of the guide rod. By arranging an elastic positioning and ejecting mechanism inside the chuck, the feeding length can be accurately controlled, the machined chuck can be automatically ejected to be unloaded, the work is reliable, and the degree of automation is high.
Description
Technical field
The present invention relates to the machining equipment field, especially the clamping device of automatic lathe.
Background technology
The chuck of lathe is used for axial workpiece is carried out clamping, common chuck structure is fairly simple, adopt the Driven by Hydraulic Cylinder fixture block, can only realize simple holding function, can not send into the degree of depth to part accurately controls, after process finishing, the realization discharging can not be ejected automatically, the requirement of equipment automatization, high accuracy processing can not be satisfied.
Summary of the invention
Defectives such as the applicant is simple in structure at above-mentioned existing lathe dog, function singleness provide a kind of clamping collet of automatic lathe rational in infrastructure, thereby improve machining accuracy, satisfy the needs of equipment automatization.
The technical solution adopted in the present invention is as follows:
A kind of clamping collet of automatic lathe, be connected the main shaft front portion of automatic lathe by flange, be fixed with the flange cover that has bell at the flange oral area, pull bar is connected with chuck and is arranged in the centre bore of flange, the front portion of chuck has the conical surface, matches with the bell of described flange cover; The endoporus of pull bar cooperates with the locating platform whorl of base, and the anterior outer peripheral face of described locating platform base connects locating platform and liftout circle; Locating platform centre hole of base matched in clearance has guide post, and the rear side of the anterior butt liftout of described guide post circle is provided with spring between guide post and the locating platform base, the sheathed stop nut in the rear end of guide post.It is further characterized in that:
Described pull bar front end outer peripheral face is provided with groove, matches with the boss of described chuck afterbody inner peripheral surface, and connects as one by securing member.
The present invention utilizes cylinder and pull bar that chuck is moved, and utilizes cone match that processed axle part is clamped, and it is convenient and effective to clamp.The present invention not only can accurately control feed length by being provided with flexible location and material jacking mechanism in chuck inside, and can eject discharging automatically, reliable operation and automaticity height after the processing.Pull bar front end outer peripheral face of the present invention matches with chuck afterbody inner peripheral surface, good concentricity, positioning accuracy height.

The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 1 and Figure 2, the clamping collet of automatic lathe of the present invention is connected the main shaft front portion of automatic lathe by flange 2, be fixed with the flange cover 5 that has bell at flange 2 oral areas, pull bar 1 front end outer peripheral face is provided with groove 14 (Fig. 3), match with the boss 13 (Fig. 2) of chuck 6 afterbody inner peripheral surfaces, the boss 13 of chuck 6 is filled in the breach and the rotation of pull bar 1 front end during assembling, boss 13 is entered in the groove 14, by holding screw 3 chuck 6 and pull bar 1 are fastenedly connected and are one, and be set in the centre bore of flange 2; The front portion of chuck 6 has the conical surface 12, matches with the bell of flange cover 5.Locating platform base 10 is connected with flange 2 by screw thread 15, and locating platform base 10 is anterior by outer peripheral face screw thread 16 connection locating platforms 4, and locating platform 4 front ends are provided with liftout circle 8, and can stretch out from the folder hole of chuck 6; Locating platform base 10 centre bore matched in clearance have guide post 7, and the rear side of guide post 7 anterior butt liftout circles 8 is provided with spring 9 between guide post 7 and the locating platform base 10, the sheathed stop nut 11 in the rear end of guide post 7.Locating platform 4 can slippage before and after locating platform base 10 peripheries under the resilient force of spring 9, and is undertaken spacing by the stop nut 11 of rear end.
Real work can be decomposed into following steps: (one) chuck 6 is in releasing orientation, this moment bar to be processed or pipe material are pressed on the folder hole of chuck 6 by manipulator, this moment, pipe material end face butt liftout circle 8, under the effect of thrust, liftout circle 8, locating platform 4 retreat the opening that enters chuck 6 and arrive the degree of depth of setting of filling in the elastic force that guide post 7 overcomes spring 9.(2) open the rear portion cylinder, pull bar 1 is pulled back, pull bar 1 drives chuck 6 and rearward moves together, because flange cover 5 is fixing, therefore under the mating reaction of the conical surface 12, chuck 6 oral areas clamp the outer rim of processed bar or pipe material, also make workpiece abut against the front end of locating platform 4 and liftout circle 8 simultaneously.(3) main axis rotation began processing work after chuck 6 clamped.(4) process finishing back stay 1 is sent to forward, the male cone (strobilus masculinus) of chuck 6 loosens, loosened the front end outer peripheral face of locating platform 4 simultaneously, this moment, guide post 7, locating platform 4 outwards ejected with liftout circle 8 under the elastic force effect of spring 9, and rod section or lasso after the cutting are ejected automatically.
More than describing is explanation of the invention, is not that institute of the present invention restricted portion is referring to claim to the qualification of invention, and under the situation of spirit of the present invention, the present invention can do any type of modification.
