Abstract
The invention relates to the technical field of a workpiece clamping. Particularly, the invention relates to an automatic centering compressing clamp. The automatic centering compressing clamp comprises a clamp body and a positioning compressing plate; a guide pillar is arranged on the clamp body, the positioning compressing plate is sleeved on the guide pillar, screwed and fixed by a nut; the positioning compressing plate comprises an upper compressing plate and a lower compressing plate which are connected through a positioning pin; an O-type ring is mounted between the lower compressing plate and the upper compressing plate. By using the automatic centering compressing clamp, a workpiece is mounted and revolved, so that the positioning gap existed when the workpiece is mounted can be removed; thereby the precision of processing the workpiece can be guaranteed; the automatic centering compressing clamp is simple and flexible in structure and relatively low in cost.
Description
Technical field
The present invention relates to the Workpiece clamping technical field, be specially the self-centering compressing fixture.
Background technology
In the rotary work piece process, need a kind of clamping device to fix workpiece, general hold down gag is made by enterprise oneself usually, on a chuck body with lead, make pressing plate with a circular iron, pressing plate one side pressure is on workpiece, the other end is fixed with nut screwing clamping, adopt the mode of matched in clearance to be fixed on the chuck body between circular iron (pressing plate) and rotary work piece to be processed, in the higher situation of processing request, this kind positioning accuracy does not satisfy the processing request of product, both caused Workpiece Machining Accuracy low, again the wasting manpower and material resources.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of self-centering compressing fixture simple in structure, ingenious, rational is provided, the positioning gap that exists when using this self-centering compressing fixture to eliminate clamping workpiece.
According to technical scheme of the present invention: the self-centering compressing fixture, comprise chuck body, positioning pressuring plate, on the described chuck body lead is set, described positioning pressuring plate is set on the lead, fix with nut screwing clamping, feature is: described positioning pressuring plate comprises lower platen and the top board that connects by alignment pin, mounting O-shaped rings between described lower platen and the described top board.
Described alignment pin is provided with three, is evenly arranged along the top board excircle.Described O type circle is elastic ring.
Described O type circle is located at the outer ring of alignment pin.
Technique effect of the present invention is: use clamping rotary work piece of the present invention, and the positioning gap that exists in the time of can eliminating clamping workpiece, thus guaranteed the precision that workpiece is processed; Simple in structure, ingenious, cost is lower.
Description of drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is the use state diagram of structure of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is further described.
Among Fig. 1, comprise lower platen 1, O type circle 2, top board 3, alignment pin 4, lead 5, nut 6, workpiece 7, chuck body 8, positioning pressuring plate 9 etc.
As shown in Figure 1, the present invention is the self-centering compressing fixture, comprise chuck body 8, positioning pressuring plate 9, on the described chuck body 8 lead 5 is set, described positioning pressuring plate 9 is set on the lead 5, tightens fixingly with nut 6, and described positioning pressuring plate 9 comprises lower platen 1 and the top board 3 that connects by alignment pin 4, mounting O-shaped rings 2 between described lower platen 1 and the described top board 3, described O type circle 2 is elastic ring.Described alignment pin 4 has three, is evenly arranged along top board 3 excircles.Described O type circle 2 is located at the outer ring of alignment pin 4.
The course of work of the present invention is as follows: workpiece 7 and positioning pressuring plate 9 are set on the lead 5 successively, then tighten fixing with nut 6, when fastening nut 6, top board 3 compresses O type circle 2 causes O type circle 2 excircle dimensions to become large, thereby tensioner makes workpiece 7 automatically adjust centering in workpiece 7 endoporus, eliminate the positioning gap that workpiece 7 clampings exist in chuck body 8, thereby improve positioning accuracy, reduce mismachining tolerance.
Use clamping rotary work piece of the present invention, the positioning gap that exists in the time of can eliminating clamping workpiece, thus guaranteed the precision that workpiece is processed; The present invention is simple in structure, ingenious, and cost is lower.
