The positioner of equipment barrel inner central tube
Technical field
The present invention relates to the technical field of equipment barrel inner central tube location.
Background technology
In order to meet the needs such as production, reaction, need to arrange central canal in equipment barrel, and require that central canal is concentric with equipment barrel.And the installation of central canal at present is not only wasted time and energy but also is difficult to reach and the requirement of equipment barrel concentricity, the once central canal normal work that will affect equipment barrel the most concentric with equipment barrel.
Summary of the invention
It is an object of the invention to: a kind of positioner that can guarantee that central canal and device cartridge body concentric equipment barrel inner central tube is provided.
For achieving the above object, the technical solution used in the present invention is: the positioner of equipment barrel inner central tube, including: equipment barrel, central canal it is provided with in equipment barrel, at least provided with three adjusting meanss between equipment barrel and central canal, the structure of each adjusting means includes: threaded sleeve, the two ends of threaded sleeve threaded one end with the first adjusting screw rod and the second adjusting screw rod respectively is connected, the other end of the first adjusting screw rod is fixedly connected on the inwall of equipment barrel, the other end of the second adjusting screw rod is fixedly connected on the outer wall of central canal, rotate threaded sleeve the first adjusting screw rod and the second adjusting screw rod to be made simultaneously to stretch out or the most inwardly shorten.
Further, the positioner of aforesaid equipment barrel inner central tube, wherein, between equipment barrel and central canal, it is evenly arranged three adjusting meanss.
Further, the positioner of aforesaid equipment barrel inner central tube, wherein, the other end of the first adjusting screw rod is welded on the inwall of equipment barrel, and the other end of the second adjusting screw rod is welded on the outer wall of central canal.
The invention have the advantage that simple in construction, easy to use, equipment barrel has been effectively ensured concentric with central canal, has substantially increased the central canal efficiency in equipment barrel inner position, also substantially increase the work efficiency that central canal is installed in equipment barrel.
Accompanying drawing explanation
Fig. 1 is the structural representation of the positioner of equipment barrel inner central tube of the present invention.
Fig. 2 is the structural representation of A-A section in Fig. 1.
Detailed description of the invention
The present invention is described in further detail with preferred embodiment below in conjunction with the accompanying drawings.
As shown in Figure 1 and Figure 2, the positioner of equipment barrel inner central tube, including: equipment barrel 1, central canal 2 it is provided with in equipment barrel 1, at least provided with three adjusting meanss between equipment barrel 1 and central canal 2, the present embodiment has been evenly arranged between equipment barrel 1 and central canal 2 three adjusting meanss, it is the most reasonable that test of many times proves to arrange three adjusting meanss between equipment barrel 1 and central canal 2, certainly, the quantity of actually used middle adjusting means can be according to the diameter Reasonable adjustment of equipment barrel.The structure of each adjusting means includes: threaded sleeve 5, the two ends of threaded sleeve 5 threaded one end with the first adjusting screw rod 3 and the second adjusting screw rod 4 respectively is connected, the other end of the first adjusting screw rod 3 is weldingly fixed on the inwall of equipment barrel 1, the other end of the second adjusting screw rod 4 is weldingly fixed on the outer wall of central canal 2, and rotation threaded sleeve 5 can make the first adjusting screw rod 3 and the second adjusting screw rod 4 stretches out simultaneously or the most inwardly shortens.
Operation principle is as follows: when installing central canal 2 in equipment barrel 1, three adjusting meanss it are evenly arranged the most respectively between equipment barrel 1 and central canal 2, the end of the first adjusting screw rod 3 stretched out from threaded sleeve 5 in each adjusting means is weldingly fixed on the inwall of equipment barrel 1, the end of the second adjusting screw rod 4 stretched out from threaded sleeve 5 is weldingly fixed on the outer wall of central canal 2;Rotate three threaded sleeves 5 the most respectively, the first adjusting rod 3 and the second adjusting rod 4 in each adjusting means are the most protruding, will the most outwards will strut with this equipment barrel and central canal that the first adjusting rod 3 and the second adjusting rod 4 are connected, the first adjusting rod 3 and the second adjusting rod 4 in each adjusting means are the most inwardly retracted, will will further respectively inwards with this equipment barrel 1 and central canal 2 that the first adjusting rod 3 and the second adjusting rod 4 are connected, after rotating threaded sleeve 5, distance between equipment barrel 1 inner tube wall and the outer tube wall of central canal 2 between the most adjacent two adjusting meanss is measured, equipment barrel 1 inner tube wall between all two adjacent adjusting meanss to the distance between central canal 2 outer tube wall the most identical time, equipment barrel 1 and central canal 3 are concentric, i.e. regulation location is complete;Then, the connecting portion of central canal 2 with equipment barrel 1 is welded and fixed;Finally, three adjusting meanss are removed.
The positioning device structure of the equipment barrel inner central tube of said structure is simple, easy to use, equipment barrel is effectively ensured concentric with central canal, substantially increase the central canal 2 efficiency in equipment barrel 1 inner position, also substantially increase the work efficiency that central canal 2 is installed in equipment barrel 1.
