Abstract
The invention provides a central positioning platform in order to solve the problem that the positioning precision is reduced because a positioning pin is easy to abrade. The central positioning platform relates to the field of positioning fixtures. The central positioning platform comprises a fixing plate which is horizontally arranged, wherein the positioning pin is fixedly arranged in the middle of the fixing plate; a positioning ring which takes the positioning pin as the center is fixed on the periphery of the positioning pin; fasteners are arranged at two ends of the fixing plate; and the positioning ring is an annular limiting lug boss which is protruded from the upper end face of the fixing plate. According to the central positioning platform, the positioning pin is used for positioning and the positioning ring is used for secondarily positioning, so that the processing precision is still ensured by the positioning ring when the positioning pin is slightly abraded.
Description
Technical field:
The present invention relates to the positioning tool field, relate in particular to a kind of centralized positioning platform.
Background technology:
In machining and welding procedure, positioning tool is the key equipment that determines machining accuracy, affects product quality, at present to adopt maximum locate modes be to cooperate with locating hole by alignment pin to position to positioning tool, have easy to use, the characteristics that locating speed is fast.But the defective by the alignment pin location is: alignment pin weares and teares easily, and such as untimely replacing, positioning accuracy can reduce, and product quality is difficult to be guaranteed.
Summary of the invention:
The object of the present invention is to provide a kind of centralized positioning platform, wear and tear easily to solve alignment pin, thus the problem that causes positioning accuracy to reduce.
For achieving the above object, the technical solution used in the present invention is:
A kind of centralized positioning platform is characterized in that: comprise horizontally disposed fixed head, be fixedly installed alignment pin in the middle of the fixed head, the alignment pin periphery is fixed with the locating ring centered by alignment pin, and described fixed head two ends are provided with securing member.
Described locating ring is for protruding the annular stop projection of fixed head upper surface.
Described locating ring is the annular spacing groove in the recessed fixed head.
The present invention not only positions by alignment pin, also carries out the secondary location by locating ring, and when a small amount of wearing and tearing occured alignment pin, locating ring still can guarantee machining accuracy.
Description of drawings:
Fig. 1 is front view of the present invention;
Fig. 2 is top view of the present invention.
1. alignment pins wherein; 2. locating ring; 3. securing member; 4. fixed head.
The specific embodiment:
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram and specific embodiment, further set forth the present invention, but be not to limit protection scope of the present invention.
Please refer to Fig. 1, Fig. 2, a kind of centralized positioning platform, comprise horizontally disposed fixed head 4, be fixedly installed alignment pin 1 in the middle of the fixed head 4, alignment pin 1 periphery is fixed with the locating ring 2 centered by alignment pin 1, fixed head 4 two ends are provided with securing member 3, and locating ring 2 is for protruding the annular stop projection of fixed head 4 upper surfaces.
More than show and described basic principle of the present invention, principal character and advantage of the present invention.It only is the specific embodiment of the present invention; but protection scope of the present invention is not limited to this; any those of ordinary skill in the art are in the disclosed technical scope of the present invention, and the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
