Abstract
The utility model relates to a self-tightening claw fixture which comprises a driving shaft used for driving a workpiece to rotate; a sliding shaft is sheathed and connected in the driving shaft in a coaxial way; the sliding shaft and the driving shaft are fixed along the circumferential direction, but can slide along the axial direction; a clamp claw used for clamping the workpiece is connected between the sliding shaft and the driving shaft; the clamp claw is driven to revolve around the axis of the driving shaft by the driving shaft; the clamp claw is articulated with the driving shaft and can swing around a hinge shaft; the end of the sliding shaft is provided with a part used for poking the clamp claw to swing, and an ejector pin used for ejecting the workpiece; when the pressure of the workpiece to the ejector pin is applied to the sliding shaft, and the sliding shaft slides, the workpiece is clamped by the clamp claw; when the sliding shaft slides towards the opposite direction, the workpiece is released by the clamp claw. The self-tightening claw fixture has the advantages that the workpiece is ejected only by the ejector pin arranged at the end of the sliding shaft so as to be automatically clamped by the clamp claw; conversely, when the workpiece is released by the ejector pin, the clamp claw is automatically loosened, so that the workpiece is time-saving and labor-saving in assembly and disassembly, and the productivity is increased.
Description
Technical field
The utility model relates to a kind of frock clamp, is especially applied in the lathes such as lathe, milling machine, for driving the frock clamp of workpiece rotation.
Background technology
In the lathes such as lathe, milling machine, for driving the frock clamp of workpiece rotation conventionally to adopt scroll chuck.Yet scroll chuck all needs staff to regulate the clamping screw on chuck in each mounting or dismounting workpiece, wastes time and energy, and has hindered the raising of productivity ratio.
Utility model content
The purpose of this utility model is to provide a kind of self-tightening pawl fixture more time saving and energy saving than scroll chuck.
The main technical schemes that the utility model is taked is: a kind of self-tightening pawl fixture, comprise and drive workpiece rotation, with the driving shaft of workpiece in same axis, in driving shaft, coaxial sleeve is connected to sliding axle, sliding axle and driving shaft are circumferentially fixing, but can in driving shaft, endwisely slip, between sliding axle and driving shaft, be at least connected with the gripper jaw of two holding workpieces, by driving shaft, drive gripper jaw to revolve round the sun around the axis of driving shaft, gripper jaw and driving shaft are hinged and can swing around jointed shaft, the end of sliding axle is provided with stirs the parts that gripper jaw swings, and the thimble of workpiece is pressed on top, when sliding axle is subject to workpiece the pressure of thimble is slided, sliding axle is stirred gripper jaw towards the direction swing of clamping work pieces, when sliding axle slides in the opposite direction, sliding axle is stirred gripper jaw and is swung towards the direction of decontroling workpiece.
As further improvement or preferred forms, the utility model also can be taked following attached technical scheme.
The described parts that gripper jaw swings of stirring that are arranged on sliding axle end, are the sheaves that is fixed on sliding axle end, and insert in the annular groove of sheave one end of described gripper jaw.
Between described driving shaft and sliding axle, be connected with spring, this spring drives sliding axle towards top, to press the direction of workpiece to slide.
One end contacting with workpiece of described gripper jaw is provided with adjustment screw, rotates adjustment screw and can change the clamping bore between gripper jaw.
The utility model has the advantages that, as long as press workpiece with the thimble top of sliding axle end, gripper jaw is clamping work pieces voluntarily just, otherwise as long as decontrol the compressing of thimble to workpiece, gripper jaw just can loosen voluntarily, installs and removes workpiece time saving and energy saving, has improved productivity ratio.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the state when clamping work pieces embodiment illustrated in fig. 1.
The specific embodiment
Referring to Fig. 1, a kind of self-tightening pawl fixture providing according to the utility model, comprise drive workpiece 9 rotations, with the driving shaft 1 of workpiece 9 in same axis, at the interior coaxial sleeve of driving shaft 1, be connected to sliding axle 2.Sliding axle 2 is provided with long keyway 3, and driving shaft 1 is fixed with guide pin 4, and guide pin 4 inserts in long keyway 3, makes sliding axle 2 and driving shaft 1 circumferentially fixing, but can in driving shaft 1, endwisely slip.
Between sliding axle 2 and driving shaft 1, be at least connected with the gripper jaw 5 of two holding workpieces 9, by driving shaft 1, drive gripper jaw 5 to revolve round the sun around the axis of driving shaft 1.The quantity of gripper jaw 5 is decided according to the actual requirements, and general needing only around uniform three gripper jaws of axis of driving shaft 1 just can meet the requirement of clamping work pieces.Each gripper jaw 5 is hinged and can swing around jointed shaft 6 with driving shaft 1.
The end of sliding axle 2 is provided with stirs the parts that gripper jaw 5 swings, and these parts are sheaves 7 that are fixed on sliding axle end, and insert in the annular groove of sheave 7 one end of gripper jaw 5.The end of sliding axle 2 is also provided with the thimble 8 that workpiece is pressed on top.Referring to Fig. 2, when sliding axle 2 is subject to the pressure F of 9 pairs of thimbles 8 of workpiece and slides, sliding axle 2 is stirred gripper jaw 5 by sheave 7 and is swung towards the direction of clamping work pieces, makes gripper jaw 5 clamping work pieces 9.After cancelling the pressure F of 9 pairs of thimbles 8 of workpiece, as long as make sliding axle 2 reset of sliding in the opposite direction, sliding axle 2 will be stirred gripper jaw 5 by sheave 7 and swing towards the direction of decontroling workpiece 9, returns to state shown in Fig. 1.Illustrated pressure F can be provided by the lathe boot that withstands the workpiece other end.
In the reset of sliding axle 2, the present embodiment is connected with spring 10 between driving shaft 1 and sliding axle 2 for convenience, and this spring drives sliding axle 2 towards top, to press the direction of workpiece 9 to slide.Under Fig. 2 state, as long as cancel the pressure F of 9 pairs of thimbles 8 of workpiece, sliding axle 2 just can automatically reset to Fig. 1 state under the effect of spring 10.
For adapting to the workpiece of different-diameter, the present embodiment is provided with adjustment screw 11 in one end contacting with workpiece of gripper jaw 5, rotates adjustment screw 11 and can change the clamping bore between gripper jaw 5.The position that adjustment screw 11 contacts with workpiece is provided with cushion pad 12, plays the effect of protection workpiece.
