The outer surface of described internal expanding tapered sleeve and the outer surface of outer expanding sleeve all are processed with a plurality of mounting grooves in order to mounting spring, make internal expanding tapered sleeve and outer expanding sleeve be close to the male cone (strobilus masculinus) of body and the outer surface of internal expanding tapered sleeve respectively in motion process.

The outer surface of described outer expanding sleeve is the netted groove structure.

The netted groove structure of described outer expanding sleeve outer surface is made of a plurality of axial grooves and a plurality of circumferencial direction groove.

A kind of processing cylinder sleeve cylindrical simultaneously that the utility model proposes and the fitting device of both ends of the surface, it has guaranteed that promptly high orientation precision has realized the axial non-displacement of cylinder liner blank in the cylinder liner blank clamping process again; The cylinder liner blank cylindrical after the processing and the concentricity of endoporus are guaranteed, make simultaneously traditionally cut the two ends operation and the turning operation is merged into a procedure, the endoporus of cast blank and the allowance of cylindrical also can significantly reduce, thereby realize that truly " lean production " also has extremely important meaning to reducing production costs.

Specific implementation process

The embodiment that provides in conjunction with the accompanying drawings is illustrated the utility model;

As shown in Figure 2, the fitting device of a kind of processing cylinder sleeve cylindrical simultaneously and both ends of the surface mainly comprises body 1, internal expanding tapered sleeve 2, outer expanding sleeve 5 and main shaft push-pull mechanism; One end of described body 1 is the frustum structure, and the other end of body is connected with the forward flange dish of machining tool main shaft; The internal taper hole of described internal expanding tapered sleeve 2 is kissed to join with the male cone (strobilus masculinus) of body 1 and is combined; Outer expanding sleeve 5 its endoporus that are positioned at internal expanding tapered sleeve 2 outsides are joined with the cylindrical of internal expanding tapered sleeve 2 kiss and are combined; The endoporus match grinding processing of the conical surface of body 1 and internal expanding tapered sleeve 2; The endoporus of the cylindrical of internal expanding tapered sleeve 2 and outer expanding sleeve 5 also is match grinding processing; After match grinding processes internal expanding tapered sleeve 2 and outer expanding sleeve 5 axially evenly are processed into 5 parts; Described main shaft push-pull mechanism is made of lower link bar 4 and push-and-pull ring 3; Described lower link bar 4 connects together with the M24 silk with the clamping cylinder that is contained in the main shaft back; Described push-and-pull ring 3 ring sets are connected one on lower link bar 4 and with lower link bar; Described internal expanding tapered sleeve 2 cooperates with the annular boss of push-and-pull ring 3 by its cannelure, constitutes the structure of internal expanding tapered sleeve 2 with push-and-pull ring 3, lower link bar 4 move left and right; The cannelure that described outer expanding sleeve 5 one ends are had cooperates with the annular boss of body 1 one ends, constitutes to stop outer expanding sleeve 5 relative body 1 axially movable position limiting structures.The outer surface of the outer surface of described internal expanding tapered sleeve 2 and outer expanding sleeve 5 all is processed with 3 mounting grooves 6, in order to mounting spring, the elastic ring hoop of five parts of internal expanding tapered sleeves 2 by spring become an integral body, with five especially the elastic ring hoop of tapered sleeve 5 by spring become an integral body, and make internal expanding tapered sleeve 2 and outer expanding sleeve 5 in motion process, be close to the male cone (strobilus masculinus) of body 1 and the outer surface of internal expanding tapered sleeve 2 respectively.When clamping, lower link bar 4 drives uses the continuous push-and-pull ring 3 of M24 silk to left movement with it, push-and-pull ring 3 drive internal expanding tapered sleeves 2 along the male cone (strobilus masculinus) of body 1 to left movement, at inner cone ringfeder 2 left in the motion process, thereby the radial dimension of inner cone ringfeder 2 increases the radial dimension of outer expanding sleeve 5 is also increased, thereby the cylinder liner blank that will overlap thereon clamps, and in outer expanding sleeve 5 radial dimension increase processes, its axial location can not change; Like this, blank does not have displacement at axial direction during clamping, makes the allowance at blank two ends be easy to control.

As shown in Figure 3, because of blanking inner hole has small portion of residual coating, must be processed into netted groove to the outer surface of outer expanding sleeve 5 for this reason, the width of groove is 3mm, dark 3mm, promptly the circumferencial direction along outer expanding sleeve 5 outer surfaces evenly is processed into 12 circumferencial direction grooves 8, axially evenly is processed into 10 axial grooves 7.So that in the blank clamping process, remaining coating can be forced in the groove after the coating of endoporus small portion of residual was subjected to radial pressure from outer expanding sleeve 5, thereby further improved the positioning accuracy of blank.Use can make after this frock traditionally cut the two ends operation and the turning operation is merged into a procedure, the endoporus of cast blank and the allowance of cylindrical also can significantly reduce, thereby realize that truly " lean production " also has extremely important meaning to reducing production costs.
