Abstract

The invention relates to a rotary excircle positioning device, and belongs to the technical field of positioning devices. The rotary excircle positioning device comprises an L-shaped substrate, a movable clamping jaw, a fixing clamping jaw, a bolt, a nut and a spring, wherein the fixing clamping jaw is welded with the L-shaped substrate; the movable clamping jaw is welded with the L-shaped substrate; a through hole is formed in the middle of the movable clamping jaw; the fixing clamping jaw is provided with a screw hole; the position of the through hole corresponds to that of the screw hole; the bolt penetrates through the through hole in the movable clamping jaw and is in threaded connection with the screw hole in the fixing clamping jaw; the spring is arranged at the position where the movable clamping jaw is fixed by the nut; and the through hole in the movable clamping jaw is in clearance fit with the bolt. By the rotary excircle positioning device, the defects of complex structure and poor clamping positioning effect of a clamping positioning device are overcome, and the work efficiency is improved.

Description

A kind of swinging excircle locating device
Technical field
The invention belongs to the positioner technical field, particularly a kind of cylindrical swinging excircle locating device.
Background technology
At present positioner a large amount of use in machining, positioner is that the workpiece of having good positioning is fixed on setting element in whole process reliably, and the occurrence positions mechanism that changes not.Do not allow to destroy the location of workpiece when clamping work pieces, and enough rigidity should be arranged, guarantee necessary detent force, but should not damage the workpiece machined surface or make workpiece produce distortion, thereby guarantee machining accuracy.Because the outer surface of most of workpiece need to be processed, for the ease of the processing of lathe to workpiece, present clamping device complex structure, and operation is comparatively inconvenient, be difficult to workpiece is positioned, or the location is firm not, makes the poor effect of its location, greatly reduce working (machining) efficiency, larger impact is played in production.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, provide a kind of simple in structure, the swinging cylindrical status device that clamping and positioning is effective.
in order to solve the problems of the technologies described above, the invention provides following technical scheme: a kind of swinging excircle locating device, comprise the L-type pedestal, movable jaw, bolt, nut, spring, described stationary jaw and the welding of L-type pedestal, movable jaw and L-type pedestal are hinged, the middle part of movable jaw is provided with a through hole, stationary jaw is provided with screw, through hole is corresponding with the position of screw, the through hole that described bolt passes on movable jaw is threaded with screw on stationary jaw, the fixing movable jaw of described bolt place is provided with spring, through hole and bolt matched in clearance on described movable jaw.
Beneficial effect: the present invention is by the simple structure of L-type pedestal, movable jaw, stationary jaw, bolt, and wherein movable jaw is rotatable, realizes the slightly different workpiece of shape size is carried out clamping and positioning, and workpiece is had clamping and positioning effect preferably.
Description of drawings
Fig. 1 is the embodiments of the invention schematic diagrames.
The specific embodiment
as shown in Fig. 1, swinging excircle locating device of the present invention comprises L-type pedestal 1, movable jaw 2, stationary jaw 3, bolt 4, nut 5, spring 6, stationary jaw 3 and 1 welding of L-type pedestal, movable jaw 2 is hinged with L-type pedestal 1, the middle part of movable jaw 2 is provided with through hole, stationary jaw 3 is provided with screw, through hole is corresponding with the position of screw, the through hole that bolt 4 passes on movable jaw 2 is threaded with screw on stationary jaw 3, the fixing movable jaw of nut 52 places are provided with spring 6, through hole and bolt 4 matched in clearance on movable jaw 2, movable jaw 2 bottoms and L-type pedestal 1 are hinged, movable jaw 2 can rotate, easier workpiece is positioned, perhaps the slightly different workpiece of shape size is positioned.
Above-described is only the preferred embodiment of the present invention; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from structure of the present invention; can also make some distortion and improvement; these also should be considered as protection scope of the present invention, and these can not affect effect of the invention process and practical applicability.
