Abstract
The invention discloses an open type thin-wall lining pressing fixture, which comprises a pressing head and a guiding sleeve, wherein the pressing head is a stepped shaft which acts following a pressing shaft of a pressing machine; the guiding sleeve which is coaxially mounted is located under the pressing head; a to-be-pressed lining is sleeved on a stopping opening at the lowest end of the pressing head; the guiding sleeve is matched and positioned with a workpiece; the length of the guiding sleeve is less than a minimum diameter of an inner hole; a conical hole having a big upper part and a small lower part is formed on an upper section of the inner hole; a diameter of a circular hole on a lower section is equal to a matched size and precision of the workpiece with the guiding sleeve; a gradually and uniformly constricting structure having a guide-protecting function is composed of the conical hole and the circular hole; and when the pressing machine moves downward, the pressing head pushes the lining to enter into an inner cavity of the workpiece along the gradually and uniformly constricting structure till being in place. Although the lining is opened, the lining is inferior in rigidity, under the guide protection of the gradually and uniformly constricting structure, the lining is reasonably pressed, the deformation is small, the pressing quality is stable and the efficiency is high. The open type thin-wall lining pressing fixture is suitable for large-scale pressing and mounting.
Description
Technical field
The present invention relates to a kind of thin-wall bush pressing clamp, specifically, the present invention relates to a kind of anchor clamps that press-fit the open type thin-wall bush to bore.
Background technology
The lining of the common inner liner abrasive resistant material of machine components endoporus of rotation at a high speed, bush structure commonly used is a thin cylinder shape, integrally-built lining rigidity is strong, press-fits in the process not yieldingly, can satisfy supporting requirements after being press-fit into place.Because integrally-built lining adopts turning to be shaped, it is many to consume material, and the consumption machined is long man-hour, thereby increases manufacturing cost.Generally speaking, to be not suitable for typical products in mass production supporting for the lining of prior art.The open type thin-wall bush adopts thin plate winding shaping technology to make, and the machine cut processing capacity is few, and stock utilization is high, significantly reduces manufacturing cost.But open type thin-wall bush rigidity is relatively poor, press-fits with original pressing clamp to be prone to produce unstable phenomenon, press-fits quality and can not satisfy supporting requirements, and the percent defective increase must increase production cost.
Summary of the invention
The present invention is primarily aimed at the deficiency of prior art, proposes a kind of open type thin-wall bush pressing clamp with the effect of protecting and leading, and this clamp structure is simple, easy to manufacture, press-fit efficient height, steady quality.
The present invention realizes technical goal through following technical proposals.
Open type thin-wall bush pressing clamp, it comprises pressure head and fairlead.Said pressure head is a kind of multidiameter with the action of press last item, and the fairlead that coaxial line is installed is positioned under the pressure head, and pressure head is seam suit lining to be press-fited bottom.Said fairlead cooperates the location with workpiece.Its improvements are: said fairlead length is less than the endoporus minimum diameter; The endoporus epimere is up big and down small conical bore; The hypomere Circularhole diameter is equal to workpiece and lining fit dimension and precision, and conical bore and circular hole are formed the locking structure of homogeneous beam gradually with the effect of protecting and leading.
In the said structure, fairlead internal taper hole tapering is 1:20～1:30, and taper hole length is longer 4～6 times than circular hole.
The present invention compared with prior art has following good effect:
1, the homogeneous beam locking structure is simple gradually, and is easy to manufacture;
2, the open type lining is descending along the internal taper hole of fairlead, realizes evenly tightening purpose gradually, and reasonable stress in the lining pressurized process, distortion are little, press-fits steady quality, efficient is high.
Description of drawings
Fig. 1 is a structural profile sketch map of the present invention.
The specific embodiment
According to accompanying drawing and combine embodiment, the present invention is described further below.
Open type thin-wall bush pressing clamp shown in Figure 1, it comprises pressure head 1 and fairlead 2.Said pressure head 1 is a kind of multidiameter with the action of press last item, and the fairlead 2 that coaxial line is installed is positioned under the pressure head 1 pressure head 1 lining 3 that the seam suit is to be press-fited bottom.Said fairlead 2 cooperates the location with workpiece 4; Fairlead 2 length are less than the endoporus minimum diameter; The endoporus epimere is up big and down small conical bore, and the hypomere Circularhole diameter is equal to workpiece 4 and lining 3 fit dimensions and precision, and conical bore and circular hole are formed the locking structure of homogeneous beam gradually with the effect of protecting and leading.Present embodiment is an east wind wheel limit bridge semiaxis straight bevel gear, its lining 3 external diameter Φ 60mm, long 40mm.So set fairlead 2 long 50mm, the long Circularhole diameter of hypomere 8mm is 60mm, and the internal taper hole tapering is 1:30, and taper hole length is 40mm.
During the actual use of the present invention; Earlier fairlead 2 is cooperated the location with workpiece 4 upper end seams; And together place under the pressure head 1, then lining 3 covers are installed to pressure head 1 lower end stop portion, it is descending to start press; Lining 3 gets into workpiece 4 inner chambers along the locking structure of being made up of fairlead 2 internal taper holes and circular hole of homogeneous beam gradually, till putting in place.Although lining 3 is open types, poor rigidity, in the present invention gradually under the protecting and leading of homogeneous beam locking structure, lining 3 reasonable stress, distortion are little, press-fit steady quality, efficient is high.
Claims (2)
1. open type thin-wall bush pressing clamp, it comprises pressure head (1) and fairlead (2); Said pressure head (1) is a kind of multidiameter with the action of press last item, and the fairlead (2) that coaxial line is installed is positioned under the pressure head (1) pressure head (1) lining (3) that the seam suit is to be press-fited bottom; Said fairlead (2) cooperates the location with workpiece (4); It is characterized in that: said fairlead (2) length is less than the endoporus minimum diameter; The endoporus epimere is up big and down small conical bore; The hypomere Circularhole diameter is equal to workpiece (4) and lining (3) fit dimension and precision, and conical bore and circular hole are formed the locking structure of homogeneous beam gradually with the effect of protecting and leading.
2. open type thin-wall bush pressing clamp according to claim 1 is characterized in that: said fairlead (2) internal taper hole tapering is 1:20～1:30, and taper hole length is longer 4～6 times than circular hole.
