Abstract
The invention discloses a bearing bush press which comprises a base, wherein a limit block is fixed on the base, a hydraulic mechanism is fixed above the limit block through a bracket and is linked with a press head through a hydraulic rod, a groove matched with the outer wall of a bearing bush is formed on the surface of the limit block, and a bulge matched with the inner wall of the bearing bush is designed on the bottom surface of the press head. Aiming the problem of the prior art, the invention aims at providing the bearing bush press. According to the invention, the bearing bush with high precision can be efficiently manufactured, and the input is relatively low.
Description
Technical field
The present invention is specifically related to a kind of bearing shell press.
Background technology
Bearing is one of critical component of steam turbine, and under the lubricated and cooling effect of circulating lubricating oil, the turbine rotor that heavy duty is run up plays a supportive role; Bearing shell is one of important building block of bearing; Be the part that bearing directly contacts with rotating shaft, be shaped as the semi-cylindrical of watt shape, its effect is to carry the active force that axle journal applies; Keep oil film stable, bearing is worked reposefully and reduce the friction loss of bearing.The operation principle of bearing shell makes bearing shell need possess following characteristic, at first, needs to adopt exotic material to process bearing shell, so that bearing shell can be high temperature resistant; Secondly, need the bearing shell medial surface be polished to enough smooth to reduce the frictional force between bearing shell and the rotating shaft as far as possible; At last, need to guarantee the radian of bearing shell medial surface.
In the prior art, a lot of to the equipment of bearing shell moulding, still, all belong to main equipment, it is excessive to use its production bearing shell to drop into, simultaneously, and the bearing shell that adopts common pressing mode to make, its wall thickness and inboard form error Shanghai Communications University need to be resolved hurrily.
Summary of the invention
Problem to prior art exists the objective of the invention is to propose a kind of bearing shell press, through enforcement of the present invention, can efficiently make the high bearing shell of precision, and drop into relatively low.
For reaching this purpose, the present invention adopts following technical scheme:
A kind of bearing shell press; Comprise base; Fixing limited block on the said base, and through support at said limited block upper fixed hydraulic mechanism, said hydraulic mechanism is through hydraulic stem interlock pressure head; Offer the groove that cooperates the bearing shell outer wall on said limited block surface, the bottom surface of said pressure head is designed to cooperate the convexity of said bearing shell inwall.
Two groups of vertical shafts of flexible connection on the said support, said vertical shaft is through the fixing said hydraulic stem of transverse axis.
The said hydraulic mechanism of digital control system control connection, input equipment connects said digital control system, can directly import the displacement that presses down of said depression bar through input equipment.
Based on disclosing of above technical scheme, the present invention possesses following beneficial effect:
The present invention places in the groove through the blank with bearing shell, through the distance that input equipment input hydraulic pressure bar presses down, and the work of digital control system control hydraulic mechanism; Make hydraulic stem order about the pressure head corresponding distance of advancing,, the bottom surface of pressure head is designed to cooperate the convexity of bearing shell inwall owing to offer the groove that cooperates the bearing shell outer wall on the limited block surface; Make through suppressing the thick product that bearing shell blank afterwards forms bearing shell; The present invention is simple in structure, makes the precision height, and efficient is high.
Description of drawings
Fig. 1 is the overall structure sketch map of the embodiment of the invention 1:
Wherein: 1, base; 2, digital control system; 3, support; 4, hydraulic stem; 5, limited block; 51, groove; 6, pressure head; 7, bearing shell; 71, outer wall; 72, inwall; 8, hydraulic mechanism; 9, transverse axis; 10, input equipment.
The specific embodiment
Further specify technical scheme of the present invention below in conjunction with accompanying drawing and through the specific embodiment:
A kind of bearing shell press is proposed; Comprise base 1; Fixing limited block 5 on the base 1, and through support 3 at limited block 5 upper fixed hydraulic mechanisms 8, hydraulic mechanism 8 is through hydraulic stem 4 interlock pressure heads 6; Offer the groove 51 that cooperates bearing shell 7 outer walls 71 on limited block 5 surfaces, the bottom surface of pressure head 6 is designed to cooperate the convexity 61 of bearing shell 7 inwalls 72.Two groups of vertical shafts 5 of flexible connection on the support 3, vertical shaft 5 is through transverse axis 9 fixer depression bars 4.Digital control system 2 control connection hydraulic mechanisms 8, input equipment 10 connects digital control system 2, can directly import the displacement that presses down of depression bar 6 through input equipment 10.
Following combine further specifying to the enforcement of embodiment 1 more clearly to show the present invention:
The blank of bearing shell 7 is placed in the groove 51, through the distance that input equipment 10 input hydraulic pressure bars 4 press down, 8 work of digital control system 2 control hydraulic mechanisms; Make hydraulic stem 4 order about the pressure head 6 corresponding distance of advancing,, the bottom surface of pressure head 6 is designed to cooperate the convexity 61 of bearing shell 7 inwalls 72 owing to offer the groove 51 that cooperates bearing shell 7 outer walls 71 on limited block 5 surfaces; Make through suppressing the thick product that bearing shell 7 blanks afterwards form bearing shell 7; The present invention is simple in structure, makes the precision height, and efficient is high.
The above; Be merely the preferable specific embodiment of the present invention; But protection scope of the present invention is not limited thereto; Any technical staff who is familiar with the present technique field is equal to replacement or change according to technical scheme of the present invention and inventive concept thereof in the technical scope that the present invention discloses, all should be encompassed within protection scope of the present invention.
