Abstract

The utility model discloses a rotary type outer circle positioning device, and relates to the technical field of positioning devices. The rotary type outer circle positioning device comprises an L-type substrate, a movable clamping jaw, a fixed clamping jaw, a bolt, a nut and a spring. The fixed clamping jaw is welded with the L-type substrate. The movable clamping jaw is hinged to the L-type substrate. A through hole is formed in the middle of the movable clamping jaw. The fixed clamping jaw is provided with a screw hole. The screw hole corresponds to the through hole in position. The bolt penetrates through the through hole in the movable clamping jaw and is in threaded connection with the screw hole in the fixed clamping jaw. The spring is arranged between the nut and the movable clamping jaw. The through hole in the movable clamping jaw is in clearance fit with the bolt. The rotary type outer circle positioning device overcomes the defects that a clamping and positioning device is complex in structure and poor in clamping and positioning effect, and improves the operation efficiency.

Description

A kind of swinging cylindrical positioner
Technical field
The utility model belongs to the positioner technical field, particularly a kind of cylindrical swinging cylindrical positioner.
Background technology
Positioner a large amount of use in machining at present, positioner is that the workpiece of having good positioning is fixed on the setting element in whole process reliably, and the mechanism that changes of occurrence positions not.When clamping work pieces, do not allow to destroy the location of workpiece, 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 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 inadequately, makes the poor effect of its location, greatly reduce working (machining) efficiency, bigger influence is played in production.
The utility model content
The utility model provides a kind of simple in structure at the deficiencies in the prior art, the swinging cylindrical status device that clamping and positioning is effective.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme: a kind of swinging cylindrical positioner, comprise L type pedestal, movable jaw, bolt, nut, spring, stationary jaw, 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 the movable jaw is threaded with screw on the stationary jaw, be provided with spring between described nut and the described movable jaw, through hole and bolt matched in clearance on the described movable jaw.
Beneficial effect: the utility model 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 embodiment schematic diagram of the present utility model.
The specific embodiment
Shown in Fig. 1, the utility model swinging cylindrical positioner comprises L type pedestal 1, movable jaw 2, stationary jaw 3, bolt 4, nut 6, spring 5, 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 the movable jaw 2 is threaded with screw on the stationary jaw 3, be provided with spring 5 between nut 6 and the movable jaw 2, through hole and bolt 4 matched in clearance on the movable jaw 2, movable jaw 2 bottoms and L type pedestal 1 are hinged, movable jaw 2 can rotate, and easier workpiece is positioned, and perhaps the slightly different workpiece of shape size is positioned.
Above-described only is preferred embodiment of the present utility model; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from the utility model structure; can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not influence effect and practical applicability that the utility model is implemented.
