Abstract
The utility model relates to a doffer combining piece adopting a steel plate welding structure, which comprises a cylinder body and a spindle, wherein an expansion bolt is arranged between the cylinder body and the spindle; and bearing components are arranged at the two ends of the spindle. Through the adoption of the steel plate welding structure, the doffer combining piece is more environment-friendly compared with the doffer combining piece adopting a casting structure; the thickness of the doffer combining piece is uniform, so that the problem of rejection caused by deflection of the casting structure is avoided; the cylindricity is high, the cutting process amount is small, and the processing efficiency is high; after the processing is finished, the unbalanced amount is small, and the running is stable, which can facilitate improvement of the cotton carding efficiency; the strength is high, stable and reliable, no deformation is generated after a card clothing is rolled, and indexes can be guaranteed; and the breadth of the doffer combining piece is increased to 1.5 m, and the doffer combining piece is suitable for the development requirements of wide-breadth cotton carding machines.
Description
Technical field
The utility model belongs to Weaving device manufacturing technology field, is specifically related to a kind of welded-steel plate construction doffer conjunction.
Background technology
General carding machine doffer conjunction cylindrical shell adopts cast structure, there are big for environment pollution, serial problems such as partially case, wall unevenness be even up and down, restricting the raising of dynamic balance accuracy and productivity ratio, the manufacture difficulty of 1.5 meters fabric width carding machine doffer conjunction blanks is bigger; Expansion set connecting pore between cylindrical shell and the main shaft is a taper hole, and difficulty of processing is big, and also not reporting for work at present to have solved the problems referred to above.
Summary of the invention
The utility model has overcome the deficiencies in the prior art, a kind of welded-steel plate construction doffer conjunction has been proposed, the cylindrical shell of described conjunction adopts welded-steel plate construction, fabric width is 1.5 meters, connect by the standard component expansion set between cylindrical shell and the main shaft, the expansion set high conformity has reduced the difficulty of processing of cylindrical shell two ends installing holes.
The technical solution of the utility model is: a kind of welded-steel plate construction doffer conjunction, comprise cylindrical shell and main shaft, and between described cylindrical shell and main shaft, be provided with the expansion set screw, be provided with bearing assembly at the two ends of main shaft.
Described cylindrical shell is cylinder.
Described cylindrical height is 1500 millimeters.
The length of described main shaft is 1857 millimeters.
The utlity model has following beneficial effect:
The utility model adopts welded-steel plate construction, more helps environmental protection than cast structure; Wall thickness is even, has avoided the inclined to one side case that cast structure produces and the problem of scrapping that causes; The cylindricity height, the machining amount is little, the working (machining) efficiency height; After machining, amount of unbalance is little, and running is stable, helps the raising of comb and parallel cotton fibers prior to spinning efficient; Intensity height, reliable and stable does not produce distortion behind the winding card clothing, every index is guaranteed.Fabric width is increased to 1.5 meters, is applicable to the demand for development of wide cut carding machine.
Description of drawings
Further specify the utility model below in conjunction with the drawings and specific embodiments.
Fig. 1 is the utility model structural representation.
Among the figure, 1. main shaft; 2. cylindrical shell; 3. expansion set screw; 4. bearing assembly.
The specific embodiment
Further specify below in conjunction with accompanying drawing, and the related scope of unrestricted the utility model.
Referring to shown in Figure 1, the utility model comprises cylindrical shell 2 and main shaft 1, is provided with expansion set screw 3 between described cylindrical shell 2 and main shaft 1, is provided with bearing assembly 4 at the two ends of main shaft 1.Described cylindrical shell 2 is cylinder, and described cylindrical height is 1500 millimeters, and the length of described main shaft 1 is 1857 millimeters.The related workpiece fabric width of the utility model is 1500 millimeters, and is indeformable in the use, and dimensional tolerance, form and position tolerance can satisfy instructions for use; Expansion set screw 3 between cylindrical shell 2 and the main shaft 1 adopts torque wrench to tighten, and guarantees to connect reliably, has improved quality and production efficiency.
