Description
Technical field
The utility model relates to a kind of numerically controlled lathe accessory, specifically the powerful claw of a kind of high rigidity with boosting mechanism.
Background technology
Numerically controlled lathe claw is installed on chuck, and for being clamped on numerically controlled lathe by workpiece to be processed, reliable clamping is the most basic guarantee of lathe in machining efficiency, machining accuracy and even personnel, lathe, workpiece safety.Traditional numeric-control lathe process heavy workpiece, often needs claw, tailstock, centre frame three coordinates can holding workpiece safely and reliably.The chucking power of tradition claw is limited, must coordinate centre frame could holding workpiece, and in addition, if workpiece needs bore hole, tailstock is also unavailable, and therefore the limitation of traditional claw is comparatively strong, only with traditional claw cannot reliable retention weight large, overhang large heavy workpiece.
Summary of the invention
Technical problem to be solved in the utility model is, for the deficiencies in the prior art, provides a kind of powerful claw of high rigidity clamping the band boosting mechanism of heavy workpiece.
The utility model solves the problems of the technologies described above adopted technical scheme: the powerful claw of high rigidity of band boosting mechanism, comprise the pintongs jaw body for clamping work pieces of filling the span of a man's arms, the inner surface of the jaw body described in every lobe is covered with steel pad, the outer surface of described steel pad is covered with copper packing, the outer surface of described copper packing is staggeredly equipped with many grooves, described copper packing and described steel pad are fixed on described jaw body by some first screws, described jaw body are provided with the boosting mechanism for clamping work pieces.
Powerful claw of the present utility model, by pintongs jaw body fill the span of a man's arms clamping work pieces time, copper packing and absorption surface, many grooves on copper packing surface can increase the clamping force of jaw body to workpiece, and copper packing hardness is less, can reduce the damage to surface of the work; During claw assembling, by reconditioning adjustment steel mat thickness or replacing adjustment steel pad, to finely tune the center of clamped workpiece; Boosting mechanism significantly can improve the clamping force of claw to workpiece, effectively can offset the decay of the clamping force that centrifugal action that workpiece rotary cutting adds man-hour causes simultaneously.After lathe adopting the powerful claw of the utility model, because the clamping rigid phase of this powerful claw is largely increased than traditional claw, therefore, the reliable retention that also can realize heavy workpiece without the need to using centre frame, thus expand the range of work of lathe, Workpiece Machining Accuracy and efficiency can be guaranteed simultaneously.
Described boosting mechanism comprises spaced some afterburning unit, afterburning unit often described in group comprises screw rod, afterburning block and the second screw, described jaw body offers cross through hole, described screw rod is threaded with described jaw body through described cross through hole, and described afterburning block is connected by the second described screw thread with described screw rod with described steel pad through described copper packing.During clamping workpiece, rotating screw bolt can drive afterburning block to press down workpiece, thus firmly, reliably clamping work pieces.
Jaw body described in every lobe is provided with four groups of afterburning unit, described four groups afterburning unit are separately positioned on the corner of every lobe jaw body.When bolt rotary stroke in these four groups afterburning unit is identical, clamping force that can be comparatively average to workpiece effect.Also suitably can increase the rotational travel of the two groups of afterburning unit being positioned at jaw body top during clamping, to offset claw " horn mouth " effect because workpiece gravity causes, provide additional clamping force by afterburning unit, guarantee the clamping rigidity of claw.
The inner side of the jaw body described in every lobe is fixed with one piece for carrying out the locating piece of axial location to workpiece, described locating piece is arranged on the below of described copper packing and described steel pad, side and the described jaw body of described locating piece are fixed, and the opposite side of described locating piece crosses out described jaw body.After clamping workpiece, its bottom is shelved on four pieces of locating pieces, and four pieces of locating pieces, in order to realize the axial location to workpiece, also can avoid workpiece to collide with pawl at the bottom of chuck, protection chuck simultaneously.
Described locating piece is fixed in described jaw body by the 3rd screw.
Jaw body described in every lobe comprises the base and rake that are wholely set, some counter sinks running through described rake and described base are offered in jaw body described in every lobe, the 4th screw is separately installed with in some described counter sinks, jaw body described in every lobe is fixedly connected with T-shaped piece on pawl at the bottom of chuck by some the 4th described screws, the bottom surface of the jaw body described in every lobe is carding tooth surface, and described carding tooth surface is positioned pawl at the bottom of described chuck.Jaw body is made up of base and rake, and rake can increase the inside surface area of jaw body, thus increases the holding area to workpiece, and makes clamping force action center closer to workpiece spindle to center of gravity, better to the clamping effect of workpiece.After dog group installs into, by carding tooth surface, jaw body is positioned pawl at the bottom of chuck, then by the 4th screw jaw body is anchored on T-shaped piece on pawl at the bottom of chuck, namely complete the assembling of claw and chuck.
Compared with prior art, the utility model has the advantage of: the powerful claw of high rigidity of the band boosting mechanism that the utility model provides, by pintongs jaw body fill the span of a man's arms clamping work pieces time, copper packing and absorption surface, many the grooves on copper packing surface can increase the clamping force of jaw body to workpiece, and copper packing hardness is less, the damage to surface of the work can be reduced; During claw assembling, by reconditioning adjustment steel mat thickness or replacing adjustment steel pad, to finely tune the center of clamped workpiece; Boosting mechanism significantly can improve the clamping force of claw to workpiece, effectively can offset the decay of the clamping force that centrifugal action that workpiece rotary cutting adds man-hour causes simultaneously.The powerful claw structure of the utility model is simple, assembling and easy to adjust, after lathe assembling this powerful claw, because the clamping rigid phase of this powerful claw is largely increased than traditional claw, therefore, the reliable retention that also can realize heavy workpiece without the need to using centre frame, thus expand the range of work of lathe, Workpiece Machining Accuracy and efficiency can be guaranteed simultaneously.
