Description
Technical field:
The utility model relates to fixture for machine tool mechanism technology field, and especially relating to a kind of part bare terminal end is the fixture of homalocephalus.
Background technology:
On lathe, when we process a part usually, need two top top tight workpieces, process behind four claw clamping part one end of chuck.If when part is round by one end that claw clamps, directly can be clamped by claw, but have the two ends of numerous parts to be all homalocephalus or irregular type, now, claw is just very unreliable to its clamping, affects machining accuracy.
Summary of the invention:
The object of the invention is to avoid existing technological deficiency, propose a kind of squashed structure workpiece special fixture.Thus efficiently solve prior art Problems existing.
Object of the present invention can by realizing by the following technical solutions: described a kind of squashed structure workpiece special fixture, be characterized in comprising spacer shell, described spacer shell is symmetrically arranged with up and down and holds out against screw, hold out against screw lower end and be provided with locating piece, described spacer shell outside is circular configuration, structure in spacer shell is the squashed structure corresponding with workpiece, and spacer shell outside is also provided with hoisting ring.
The described screw that holds out against is four, holds out against between screw and spacer shell and is also provided with thread bush, and it is two that described hoisting ring is symmetrical arranged.
Described spacer shell outside diameter is less than or equal to the minimum diameter that machine tool jaw holds, and spacer shell is interior is matched in clearance with workpiece.
The beneficial effects of the utility model are: described a kind of squashed structure workpiece special fixture, it realizes the clamping transition of homalocephalus shape workpiece, apparatus structure is simple, easy to loading and unloading, especially workpiece two ends be homalocephalus or irregular head dummy time, the fixture that is once installed can be realized, batch machining same size workpiece.
Accompanying drawing illustrates:
Fig. 1 is the utility model structural principle schematic diagram;
Fig. 2 is the enforcement structural representation that the utility model is applied on lathe.
Shown in figure: 1, spacer shell, 2, locating piece, 3, thread bush, 4, hold out against screw, 5, hoisting ring, 6, chuck, 7, claw, 8, top, 9, workpiece.
Detailed description of the invention:
Below in conjunction with accompanying drawing shownschematically most preferred embodiment be described in further detail:
As illustrated in fig. 1 and 2, described a kind of squashed structure workpiece special fixture, be characterized in comprising spacer shell 1, described spacer shell about 1 is symmetrically arranged with and holds out against screw 4, hold out against screw 4 lower end and be provided with locating piece 2, described spacer shell 1 outside is circular configuration, and the structure in spacer shell 1 is the squashed structure corresponding with workpiece 9, and spacer shell 1 outside is also provided with hoisting ring 5.
Described to hold out against screw 4 be four, and hold out against between screw 4 and spacer shell 1 and be also provided with thread bush 3, it is two that described hoisting ring 5 is symmetrical arranged.
Described spacer shell 1 outside diameter is less than or equal to the minimum diameter that machine tool jaw 7 holds, and spacer shell 1 is interior is matched in clearance with workpiece 9.
Described a kind of squashed structure workpiece special fixture, during use, grip device is lifted by crane by hoisting ring 5, is arranged on machine chuck 6, and with the spacer shell 1 on claw 7 gripping mechanism, workpiece 9 is arranged on the spacer shell 1 of device, two top 8 top tight workpieces, hold out against screw 4 by upper and lower four of stubborn top, make four locating piece 2 top tight workpieces 9, and workpiece 9 is located, now can machined workpiece.After completion of processing, unclamping and hold out against screw 4, the workpiece machined is taken off, without the need to pulling down grip device, to be installed all the other unprocessed workpiece by above-mentioned same procedure.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
