Abstract
The utility model relates to a floating distribution claw clamping device. A claw seat (1), a floating platen (7) and a small bridge platen (4) are arranged on a claw (6) of a chuck of a regular machine tool, wherein, the claw is stretched to an open slot of the claw seat, the claw seat, the floating platen and the small bridge platen are connected by a long screw (8) provided with a spring (9), thus form a conical structure with a plurality of intervals between the floating platen and the small bridge, as well as the floating platen and the small bridge, then constantly keep the floating platen and the small bridge in an elastic floating condition. Because the utility model can achieve ideal joint with the shape of a columniform or conical workpiece, and evenly distribute clamp force to a thin-wall part, thus reduce deformation of the part, and keep the part under a good clamping state, so increase cutting rate and improve production efficiency and processing precision.
Description
One, technical field
The utility model relates to the machine tooling Workpiece clamping device.
Two, technical background
At present lathe is when machining cylindrical component endoporus, for example grinding, turning, boring etc., and normally used Workpiece clamping device is a scroll chuck, carries out the claw clamping work pieces.This clamping means, claw contacts with the direct rigidity of workpiece, because unbalance stress very easily causes thin-walled parts generation distortion and influences machining accuracy.When the workpiece profile is taper, just can't clamp with chuck jaws usually.In order to address this problem, adopt the even power claw clamping device that floats, the workpiece clamping force is evenly distributed, reduce the thin-walled parts distortion, enhance productivity and machining accuracy.
Three, summary of the invention
The utility model is taked at machine chuck claw upper mounting jaw seat, floating platen and little bridge plate, effect by the connection of ball wimble structure and long spiro nail, spring, make the clamp force distribution equilibrium of claw, reach the clamping distortion that reduces thin-wall workpiece, improve the purpose of cutting data and machining accuracy.
The utility model is to realize like this, even power claw clamping device floats, chuck jaws stretches in the open slot on the pawl seat, and fix by holding screw, pawl seat one side connects with long spiro nail with floating platen, opposite side runs through floating platen with long spiro nail and connects with the foot bridge plate, between long spiro nail and the pawl seat spring is installed, between pawl seat and the floating platen, connect with the ball wimble structure by the middle steel ball on the taper ball seat that is positioned at planar central position on pawl seat lower plane center and the floating platen, between floating platen and the little bridge plate, connect with the ball wimble structure by the side steel ball on the taper ball seat that is positioned at planar central position on floating platen one side lower plane and the little bridge plate, all have the gap between pawl seat and the floating platen and between floating platen and the little bridge plate.
In the above-mentioned even power claw clamping device that floats, the interior side-lower of floating platen and little bridge plate keeps and the outer identical cylinder of garden radius of workpiece.
In the above-mentioned even power claw clamping device that floats, middle steel ball size also can be equal to or less than the side steel ball size greater than the side steel ball size.
Owing to adopt the even power claw clamping device that floats, make clamping device can with the desirable applying of cylindrical or tapered profile of workpiece, and clamping force is delivered on the thin-walled parts equably, reduce workpiece deformation, thereby can strengthen cutting data, enhance productivity and machining accuracy.
Four, description of drawings
Fig. 1 is the schematic diagram of the even power claw clamping device that floats; Fig. 2 is the A-A profile of Fig. 1.
Among the figure, 1 is the pawl seat, and 2 is the side steel ball, and 3 is holding screw, and 4 is little bridge plate, and 5 is middle steel ball, and 6 is claw, and 7 is floating platen, and 8 is long spiro nail, and 9 is spring, and 10 is cylinder, and 11 is workpiece.
Five, preferred forms
Preferred forms of the present utility model is provided by following accompanying drawing.
Referring to Fig. 1, machine chuck claw 6 stretches in the open slot on the pawl seat 1, and is fixed by two holding screws 3.1 long spiro nail 8 of pawl seat 1 one sides and floating platen 7 usefulness connects, its opposite side runs through floating platen 7 with two long spiro nails 8 and connects with foot bridge plate 4, between long spiro nail 8 and the pawl seat 1 spring 9 is installed, between pawl seat 1 and the floating platen 7, connect with the ball wimble structure by the middle steel ball 5 on the taper ball seat that is positioned at planar central position on 1 time flat center of pawl seat and the floating platen 7, between floating platen 7 and the foot bridge plate 4, connect with the ball wimble structure by the side steel ball 2 on the taper ball seat that is positioned at planar central position on floating platen 7 one side lower planes and the foot bridge plate 4, there is clearance delta respectively between pawl seat 1 and the floating platen 7 and between floating platen 7 and the foot bridge plate 4, makes floating platen 7 and foot bridge plate 4 be in the elastic floating state all the time.When the diameter of middle steel ball 5 diameter greater than side steel ball 2, the cone angle of taper ball seat is 90.Clearance delta is 2 millimeters, when the interior side-lower of floating platen 7 and foot bridge plate 4 keeps the cylinder 10 identical with workpiece 11 outer garden radius Rs, the effect of the ball wimble structure by pawl seat 1, long spiro nail 8, spring 9 and middle steel ball 5, side steel ball 2 places, just can make the clamping force of machine chuck claw 6, stepless action is on the outer garden of cylindrical or taper thin-wall workpiece 11, thereby reduce the distortion of workpiece 11, make the desirable applying of clamping device and workpiece 11 profiles, thereby be implemented under the reliable clamped condition, can strengthen cutting data, enhance productivity and machining accuracy.
