Abstract
The utility model is intended to provide a kind of Combined fixture positioning concentric shafts, comprising: boss 1, locating shaft 1, non-locating axis 1, non-locating axis 2, locating shaft 2, boss 2；Non-locating axis 1 and non-locating axis 2 are completed connection and are disconnected by turning screw thread.It can not only guarantee the requirement on machining accuracy of concentricity, and structure is simple, operation is convenient, it is lower to require working space, work efficiency is high, popularization easy to use.
Description
Technical field
The present invention relates to frame for movement technical field, more particularly to a kind of Combined fixture positioning concentric shafts.
Background technique
With the development of assembly technology, it is increasingly recognised that the importance of assembly technology in production；It is same for having
The revolving structure that axis degree requires, if the accuracy of its concentricity cannot be effectively ensured, that can be used for performance and use the longevity
Life is brought and is seriously affected, thus now tool locating with concentric shafts in production using more and more extensive, but existing work
Set position be an integral structure with concentric shafts it is more demanding to working space when being inserted and removed from, in the feelings of some narrow spaces
Under condition, it is not convenient to use.
Entitled " a kind of tool locating use of application number " 201420780090 " in Chinese invention patent application prospectus
Concentric shafts " disclose a kind of tool locating concentric shafts, the tool locating concentric shafts, and structure includes: locating shaft 1, non-fixed
Concentric shafts one end is first inserted into tool locating seat by position axis 2 and boss 3, when use, gently taps outside boss 3, allows concentric shafts
Forefront position portion slowly enter in workpiece, after workpiece is welded in tooling, from interior survey tap boss 3, allow with one heart
Axis is slowly withdrawn, and then carries out workpiece to turn sequence；The tool locating of this form with concentric shafts be an integral structure insertion and
When taking-up, need to complete from the unilateral side of workpiece, it is more demanding to working space on the whole, in the case where some narrow spaces,
Especially workpiece takes out tool locating concentric shafts working space deficiency, there are interference problems, cause tooling after the completion of welding
Positioning is not available with concentric shafts.
Summary of the invention
The present invention is intended to provide a kind of Combined fixture positioning concentric shafts, can not only guarantee the machining accuracy of concentricity
It is required that and structure is simple, operation is convenient, it is lower to require working space, work efficiency is high, popularization easy to use.
In order to achieve the above objectives, the present invention is implemented with the following technical solutions.
A kind of Combined fixture positioning concentric shafts disclosed by the invention, comprising: boss 1, locating shaft 1, non-locating axis 1,
Non-locating axis 2, locating shaft 2, boss 2；In use, first non-locating axis 1 and non-locating axis 2 are completed to connect by turning screw thread；
Combined fixture positioning concentric shafts are inserted into workpiece 1, concentric locating is completed, then workpiece 1 is welded on workpiece 2, are welded
After the completion of connecing, non-locating axis 1 is disconnected with non-locating axis 2 by turning screw thread, then respectively from the medium position of workpiece 1
It individually takes out, solves the problems, such as unilateral taking-up, reduce working space on the whole, avoid interference with and meet process requirements.

Specific embodiment
With reference to the accompanying drawings and detailed description, the present invention is furture elucidated.
Schematic structural view of the invention, referring to Fig. 1 and Fig. 2；Operation schematic diagram of the present invention, referring to Fig. 3 and Fig. 4.
A kind of such as Fig. 1, Combined fixture positioning concentric shafts disclosed by the invention, comprising: boss 1(1), locating shaft 1
(2), non-locating axis 1(3), non-locating axis 2(4), locating shaft 2(5), boss 2(6)；Such as Fig. 2, in use, first by non-locating axis 1
(3) it completes to connect by turning screw thread with non-locating axis 2(4)；Such as Fig. 3, Combined fixture positioning concentric shafts are inserted into workpiece 1
(7) in, concentric locating is completed, workpiece 1(7) is then welded in workpiece 2(8) on；Such as Fig. 4, after the completion of welding, by non-locating axis
It 1(3) is disconnected with non-locating axis 2(4) by turning screw thread, is then individually taken out from the center of workpiece 1(7) respectively,
It solves the problems, such as unilateral taking-up, reduces working space on the whole, avoid interference with and meet process requirements.
