Abstract
The utility model discloses a guide apparatus which has the advantages that an oil film on the surface of the part, between a first through hole and a wear reducing sleeve, of a piston rod can be prevented from being easily damaged, the lubricating effect is good and the structure is simple. The guide apparatus comprises a body (1), wherein the body (1) is sequentially provided with a first through hole (6) for slide fitting with the piston rod and a second through hole (7) for containing the wear reducing sleeve from the left to the right, the first through hole (6) and the second through hole (7) are coaxially formed, a ring platform (8) is arranged at a transition position between the first through hole (6) and the second through hole (7), the ring platform (8) is provided with at least one radial groove, and the radial groove is communicated with the first through hole (6).
Description
Technical field
The utility model relates to vibration damper technical field, is specifically a kind of guider.
Background technique
Guider comprises body, body is sequentially provided with first through hole of joining for piston rod cunning and from left to right for holding the second through hole of anti-attrition cover (being generally copper sheathing), the first through hole and the second through hole coaxially arrange, anti-attrition cover also with piston rod sliding fit, the first through hole and the second through hole transition position are a ring-shaped platform, said structure is as shown in Fig. 1 that notice of authorization number is CN201757149U, the defect of this structure is, it is easily destroyed that piston rod is positioned at this part surperficial oil film of the first through hole and anti-attrition cover, especially in high-speed motion situation, therefore, in the course of time, will cause piston rod, all may there are larger wearing and tearing in the first through hole and anti-attrition cover, thereby reduce vibration damper performance.
Model utility content
The technical problems to be solved in the utility model is, provides a kind of this part surperficial oil film that can make piston rod be positioned at the first through hole and anti-attrition cover to be difficult for destroyed, lubricated good, and guider simple in structure.
The technical solution of the utility model is, the utility model guider, it comprises body, body is sequentially provided with first through hole of joining for piston rod cunning and the second through hole overlapping for holding anti-attrition from left to right, the first through hole and the second through hole coaxially arrange, the first through hole and the second through hole transition position are a ring-shaped platform, and described ring-shaped platform is provided with at least one radial groove, and this radial groove is communicated with the first through hole.
Adopt after said structure, the utility model compared with prior art, have the following advantages: because described ring-shaped platform is provided with at least one radial groove, this radial groove is communicated with the first through hole, and after the second through hole assembling anti-attrition cover, between anti-attrition cover end face and ring-shaped platform, still there is gap, this gap is ringwise around piston rod, can exert an influence to the oil film of piston rod surface, so, by radial groove oil suction, drain the oil, just can make gap remain suitable oil mass, gap remains that suitable oil mass just can make piston rod at this first through hole, anti-attrition cover place forms stable oil film while moving, having improved greatly the profit at this place changes, wearing and tearing have been alleviated, improved the performance of vibration damper, from technological scheme, the utility model is simple in structure, so the utlity model has this part the surperficial oil film that can make piston rod be positioned at the first through hole and anti-attrition cover be difficult for destroyed, lubricated good, and advantage simple in structure.
As improvement, when radial groove is a plurality of, a plurality of radial grooves are circumferentially uniform along the first through hole, and like this, groove distributing equilibrium, makes body stress equalization, are therefore more conducive to the raising of the utility model performance.
As improvement, radial groove is V-shaped groove, like this, is more conducive to the demoulding that powder metallurgy is manufactured, and is more conducive to the production convenience of the utility model performance and the raising of quality stability.
As improvement, ring-shaped platform outward edge and the second through hole joint arc transition, like this, be applicable on the one hand powder metallurgy manufacture, improve on the other hand mechanical property herein, moreover anti-attrition cover is played to certain positioning action, and make gap control between anti-attrition cover end face and ring-shaped platform in required value, the formation in gap is stablized controlled.

Shown in figure, 1, body, 2, first portion, 3, second portion, 4, planar annular, 5, fillet, the 6, first through hole, the 7, second through hole, 8, ring-shaped platform, 9, V-shaped groove, 10, circular arc.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
The utility model guider, it comprises body 1, body 1 is sequentially provided with first through hole 6 of joining for piston rod cunning and the second through hole 7 overlapping for holding anti-attrition from left to right, the first through hole 6 and the second through hole 7 coaxially arrange, the first through hole 6 and the second through hole 7 transition positions are a ring-shaped platform 8, described ring-shaped platform 8 is provided with at least one radial groove, and this radial groove is communicated with the first through hole 6.
When radial groove is a plurality of, a plurality of radial grooves are circumferentially uniform along the first through hole 6.
Radial groove is V-shaped groove 9.
Ring-shaped platform 8 outward edges and the second through hole 7 joint circular arc 10 transition.
In this example, two V-shaped grooves 9 are radially set on described ring-shaped platform 8.
In this example, body 1 one end is the cylindrical body being connected with pipe, described cylindrical body comprises coaxial two-part from left to right, the diameter of first portion 2 is greater than the diameter of second portion 3, first portion 2 is a planar annular 4 with second portion 3 transition positions, and described body 1 one end is for referring to that with managing the cylindrical body being connected cylindrical first portion 2 is for being connected with pipe, and first portion 2 is [10 of closed intervals with the span of the difference of the diameter of second portion 3,16], second portion 3 end faces are provided with fillet 5.
Between pipe and second portion 3, form annular space, the size of annular space is definite with the difference of the diameter of second portion 3 by first portion 2, and this annular space plays the effect of a buffering, and fluid scouring effect is significantly reduced; And in [10,16] scope, be not only beneficial to manufacture, and in fluid, most of impurity cannot be invaded in annular space, further reduces scouring effect; Second portion 3 end faces are provided with fillet and have guiding and buffer function, not only reduce Oil shocking, and are convenient to assembling.
First portion 2 is equal in length with second portion 3.
Length between first portion 2 and second portion 3 also can be unequal, is generally that the length of first portion 2 is greater than the length of second portion 3, but should has as far as possible larger depth, and like this, cushioning effect just can be better.
Directivity is from left to right described based on direction shown in the drawings.
Silk is the conventional unit of Machine Design and processing, is scaled 1=0.01 millimeter=10 microns.
