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 needs such as satisfied production, reactions, need to arrange central tube in equipment barrel, and require that central tube is concentric with equipment barrel.And the installation of central tube is not only wasted time and energy but also is difficult to reach the requirement with equipment barrel concentricity, once central tube and equipment barrel decentraction will affect the normal work of equipment barrel at present.
Summary of the invention
The object of the invention is: a kind of positioner that can ensure central tube and the body concentric equipment barrel inner central tube of device cartridge is provided.
For achieving the above object, the technical solution used in the present invention is: the positioner of equipment barrel inner central tube, comprise: equipment barrel, central tube is provided with in equipment barrel, three adjusting devices are at least provided with between equipment barrel and central tube, the structure of each adjusting device comprises: threaded sleeve, the two ends of threaded sleeve are connected with the threaded one end of the first adjusting screw(rod) and the second adjusting screw(rod) respectively, 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 tube, rotating threaded sleeve can make the first adjusting screw(rod) and the second adjusting screw(rod) outwards extend simultaneously or inwardly shorten simultaneously.
Further, the positioner of aforesaid equipment barrel inner central tube, wherein, has been evenly arranged three adjusting devices between equipment barrel and central tube.
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 tube.
Advantage of the present invention is: structure is simple, easy to use, effectively ensure that equipment barrel is concentric with central tube, substantially increases the efficiency of central tube in equipment barrel inner position, also substantially increases the operating efficiency that central tube is installed in equipment barrel.

Detailed description of the invention
Below in conjunction with accompanying drawing and preferred embodiment, the present invention is described in further detail.
As shown in Figure 1 and Figure 2, the positioner of equipment barrel inner central tube, comprise: equipment barrel 1, central tube 2 is provided with in equipment barrel 1, three adjusting devices are at least provided with between equipment barrel 1 and central tube 2, between equipment barrel 1 and central tube 2, three adjusting devices have been evenly arranged in the present embodiment, it is the most reasonable that test of many times proves between equipment barrel 1 and central tube 2, arrange three adjusting devices, certainly, in actual use, the quantity of adjusting device can according to the diameter Reasonable adjustment of equipment barrel.The structure of each adjusting device comprises: threaded sleeve 5, the two ends of threaded sleeve 5 are connected with the threaded one end of the first adjusting screw(rod) 3 and the second adjusting screw(rod) 4 respectively, 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 tube 2, rotates threaded sleeve 5 and the first adjusting screw(rod) 3 and the second adjusting screw(rod) 4 can be made outwards to extend simultaneously or inwardly shorten simultaneously.
Operation principle is as follows: in equipment barrel 1 during mounting center pipe 2, first between equipment barrel 1 and central tube 2, be evenly arranged three adjusting devices respectively, the welding edges of the first adjusting screw(rod) 3 stretched out from threaded sleeve 5 in each adjusting device is fixed on the inwall of equipment barrel 1, the welding edges of the second adjusting screw(rod) 4 stretched out from threaded sleeve 5 is fixed on the outer wall of central tube 2, then three threaded sleeves 5 are rotated respectively, protruding the while of the first adjusting rod 3 in each adjusting device and the second adjusting rod 4, will by with this equipment barrel be connected the first adjusting rod 3 and the second adjusting rod 4 and central tube respectively to strutting outward, the first adjusting rod 3 in each adjusting device and the second adjusting rod 4 are inwardly retracted simultaneously, will further with this equipment barrel 1 be connected the first adjusting rod 3 and the second adjusting rod 4 and central tube 2 respectively to interior, after rotating threaded sleeve 5, distance between equipment barrel 1 inner tube wall often between adjacent two adjusting devices and the outer tube wall of central tube 2 is measured, when equipment barrel 1 inner tube wall between all two adjacent adjusting devices is all identical to the distance between central tube 2 outer tube wall, equipment barrel 1 and central tube 3 concentric, namely regulate location complete, then, the connecting portion of central tube 2 with equipment barrel 1 is welded and fixed, finally, three adjusting devices are removed.
The positioning device structure of the equipment barrel inner central tube of said structure is simple, easy to use, effectively ensure that equipment barrel is concentric with central tube, substantially increase the efficiency of central tube 2 in equipment barrel 1 inner position, also substantially increase the operating efficiency that central tube 2 is installed in equipment barrel 1.
