Abstract
The utility model relates to a guide pillar assembly, and particularly relates to a bush of the guide pillar assembly. The bush of the guide pillar assembly comprises a bush main body, wherein the bush main body is provided with a plurality of rollers, and center shafts of the rollers are perpendicular to the center shaft of the bush main body; the rollers comprise columniform roller main bodies, the two ends of the roller main bodies are provided with contacting parts with outer convex waist drum shapes, the contacting parts are provided with arc surfaces, and the arc surfaces are matched with a guide pillar outer ring of the guide pillar assembly and an inner circumference surface of a guiding sleeve. The bush provided by the utility model is ingeniously provided with the rollers which comprise the roller main bodies and the contacting parts, the bush is assembled on the guide pillar assembly, the peripheries of the roller main bodies of the roller and the arc surfaces of the contacting parts are simultaneously contacted with the periphery surface of a guide pillar, namely, tangency; and at this time, the contacting parts are both tangent with the inner circumference surface of the guiding sleeve, the line-line contact is realized, a contacting area is increased, and the rigidity, precision and stability of the guide pillar assembly are improved.
Description
Technical field
The utility model relates to a kind of guide pillar assembly, relates in particular to a kind of lining of guide pillar assembly.
Background technology
China mainly uses ball guide pillar assembly in the high speed stamping field at present, and its lining is provided with steel ball, has high accuracy and lower use cost.Simultaneously also exist some problems: because steel ball is a contact, so rigidity is lower, although can improve some rigidity by increasing the precompressed amount, the impact when steel ball pours is larger, can produce vibration, affects precision and the life-span of assembly.Therefore, in some rigidity and the higher diel of required precision, ball guide pillar assembly just is difficult to successfully manage, and has affected the normal use of mould, has reduced the production efficiency of enterprise.
Summary of the invention
In order to address the above problem, the utility model provides a kind of lining that can make the guide pillar assembly have the guide pillar assembly of relatively high precision, rigidity and stability.
To achieve these goals, the utility model is mainly solved by the following technical programs: a kind of lining of guide pillar assembly, comprise the lining main body, the lining main body is provided with several rollers, the central shaft of the central shaft of roller and lining main body is perpendicular, and described roller comprises columniform roller body, and the two ends of roller body are provided with the dolioform contact site of evagination, contact site is provided with arc surface, and the guide pillar outer ring face of arc surface and guide pillar assembly and the inner peripheral surface of guide pin bushing are complementary.
As preferably, above-mentioned roller is evenly distributed on described lining main body side by side.
As preferably, above-mentioned adjacent two rows' rollers are dislocatedly distributed.
As preferably, above-mentioned roller is embedded on described lining main body.
The ingenious roller that comprises roller body and contact site that is provided with on lining of the utility model, when lining was assemblied on the guide pillar assembly, the periphery of the roller body of roller and the arc surface of contact site contact with the outer peripheral face of guide pillar simultaneously, and be namely tangent; This moment, contact site was simultaneously tangent with the inner peripheral surface of guide pin bushing, realized the contact of line line, increased contact area, thereby rigidity, the precision and stability of guide pillar assembly have been improved, and then the service life of having improved the guide pillar assembly, and can effectively reduce the wearing and tearing of the miscellaneous part of mould, greatly improve the mold use life-span and increased the production efficiency of enterprise.

The specific embodiment
Below in conjunction with accompanying drawing 1-2, the specific embodiment of the technical solution of the utility model is described in further detail.
Embodiment: a kind of lining of guide pillar assembly, comprise lining main body 1, lining main body 1 is provided with several rollers 2, and the central shaft of the central shaft of roller 2 and lining main body 1 is perpendicular, and when guaranteeing work, roller 2 can roll.Roller 2 is evenly distributed on described lining main body 1 side by side, makes it stressed evenly, improves rigidity, the precision and stability of guide pillar assembly.For convenient processing and installation, roller 2 can adopt and be embedded on lining main body 1.Adjacent two rows' rollers 2 are dislocatedly distributed, and make between roller 2 to distribute compactlyer, further improve rigidity, the precision and stability of guide pillar assembly, thereby have improved the service life of guide pillar assembly.
