Abstract
The invention discloses a cambered cushion block, which is characterized by being in the shape of a spherical crown body and consisting of an upper spherical shell and a lower spherical crown body, wherein the spherical shell covers the spherical crown body; the joint surface between the spherical shell and the spherical crown body is provided with a plurality of small oil accumulating cavities and a plurality of flow channels for communicating the oil accumulating cavities; the top surface of the spherical shell is provided with small holes which are communicated with the small oil accumulating cavities; the small holes are uniformly distributed in the top surface of the spherical shell. The cambered cushion block is adopted instead of a spherical gasket, and has the advantages of high lubricating performance, difficulty in wearing, and optimization of the structure of a bottom side part of the cushion block; a spherical surface does not need to be processed on the part on the bottom side of the cushion block, so that the structure and machining process become simple.
Description
Technical field
The present invention relates to a kind of curved surface cushion block in the moving contact of sphere workplace application.
Background technique
Because the moving contact of sphere has the effect of eliminating coaxiality error, so be applied on the precision equipments such as automobile, numerical control.The General Construction of the moving contact combination of current sphere is: to sphere is moving, contact relevant two two, a part processing outer spherical surface, a part working inner sphere, centre arranges the easily damaged parts spherical pad, and the inside and outside spherical surface of spherical pad contacts with outer spherical surface with the inner ball surface of two parts respectively.The shortcoming of said structure is: correlated parts and spherical pad need to be processed four spheres, and the sphere labor content is large, require the process equipment precision high, also make the design of part complexity simultaneously; It is easy to wear that the while spherical pad can not get good lubrication when work, and the replacement cycle is short, to maintenance, brings very big inconvenience.
Summary of the invention
In view of the problem that current known technology exists, the technical problem to be solved in the present invention is to be to provide a kind of replacement spherical pad application, not easy to wear, makes that correlated parts is simple in structure, the curved surface cushion block of work simplification.
For solving the problems of the technologies described above, the present invention implements by the following technical programs:
A kind of curved surface cushion block, it is characterized in that: this curved surface cushion block is the ball-crown body shape, by the spherical shell on top and the ball-crown body of bottom, formed, spherical shell covers on ball-crown body, both junction planes are provided with and a plurality ofly hold oily areola and hold by a plurality of the runners that oily areola is communicated with, the end face of spherical shell is provided with Small Holes and communicates with holding oily areola, and Small Holes is evenly laid at the end face of spherical shell.
The curved surface cushion block that technique scheme provides, only having top is sphere, corresponding with it, only be positioned at the part working inner sphere of curved surface cushion block top side, and the part that is positioned at curved surface cushion block bottom side does not just need to process outer spherical surface, so, three parts (comprising the curved surface cushion block) of the moving contact combination of sphere only need two spheres of processing, the sphere labor content reduces half, and the design of part that also makes not process sphere is simple, processing technology is simplified.In addition, curved surface cushion block inside is provided with holds oily areola and runner, makes the end face Small Holes of curved surface cushion block spherical shell when work obtain sufficient good lubrication between can be for spherical shell end face and contact part, and the curved surface cushion block is difficult for wearing and tearing, the replacement cycle of moving contact combination is long, to maintenance, brings convenience.
As optimal technical scheme, spherical shell adopts copper product, and ball-crown body adopts aluminum alloy material, and both are fixedly connected with by brazing mode.Above-mentioned design makes the curved surface cushion block wear-resisting and lightweight, and overall structure is firm.
The accompanying drawing explanation
The present invention has following accompanying drawing:
The front view that Fig. 1 is the curved surface cushion block,
The A-A view that Fig. 2 is Fig. 1.
Embodiment
Below by specific embodiment, the present invention is described in detail:
As shown in the figure, curved surface cushion block of the present invention, for the ball-crown body shape, by the spherical shell 1 on top and the ball-crown body 2 of bottom, formed, spherical shell 1 adopts copper product, ball-crown body 2 adopts aluminum alloy material, both are fixedly connected with by brazing mode, and spherical shell 1 covers on ball-crown body 2, and both junction planes are provided with and a plurality ofly hold oily areola 4 and hold by a plurality of the runners 5 that oily areola 4 is communicated with, the end face of spherical shell 1 is provided with Small Holes 3 and communicates with holding oily areola 4, and Small Holes 3 is evenly laid at the end face of spherical shell 1.
Claims (2)
1. a curved surface cushion block, it is characterized in that: this curved surface cushion block is the ball-crown body shape, by the spherical shell on top and the ball-crown body of bottom, formed, spherical shell covers on ball-crown body, both junction planes are provided with and a plurality ofly hold oily areola and hold by a plurality of the runners that oily areola is communicated with, the end face of spherical shell is provided with Small Holes and communicates with holding oily areola, and Small Holes is evenly laid at the end face of spherical shell.
