Abstract
The utility model discloses a curved surface cushion block which is characterized by being of a spherical crown body shape and consisting of a spherical shell at the upper part and a spherical crown body at the lower part, wherein the spherical shell covers the spherical crown body; the bonding surface of the spherical shell and the spherical crown body is provided with a plurality of oil storage small cavities and flow passages for communicating the plurality of oil storage small cavities; the top surface of the spherical shell is provided with small holes communicated with the oil storage small cavities; and the small holes are uniformly distributed on the top surface of the spherical shell. The curved surface cushion block replaces a spherical gasket to be applied and has the advantages that the curved surface cushion block has good lubricating performance and is difficult to wear, the structure of a part at the bottom side of the cushion block is optimized, and the part at the bottom side of the cushion block does not need to be subjected to spherical surface processing, so that the structure and a machining process of the part at the bottom side of the cushion block are simple.
Description
Technical field
The utility model 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 equipment such as automobile, numerical control.The General Construction of the moving contact combination of current sphere is: contact relevant two two to sphere is moving, a part processing outer spherical surface, a part working inner sphere, centre arranges 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 sphere labor content is large, requires process equipment precision high, also makes design of part complexity simultaneously; It is easy to wear that while spherical pad can not get good lubrication in the time of work, and the replacement cycle is short, brings very big inconvenience to maintenance.
Summary of the invention
In view of the problem that current known technology exists, the technical problems to be solved in the utility model is to be to provide a kind of spherical pad application, not easy to wear that replaces, and 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 utility model is implemented by the following technical programs:
A kind of curved surface cushion block, it is characterized in that: this curved surface cushion block is ball-crown body shape, formed by the spherical shell on top and the ball-crown body of bottom, spherical shell covers on ball-crown body, both junction planes are provided with and multiplely hold oily areola and hold by multiple 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 curved surface cushion block) of the moving contact combination of sphere only need two spheres of processing, sphere labor content reduces half, and the design of part that also makes not process sphere is simple, processing technology is simplified.In addition, what curved surface cushion block inside was provided with holds oily areola and runner, and the end face Small Holes that makes curved surface cushion block spherical shell in the time of work can be to obtain sufficient good lubrication between spherical shell end face and contact part, and curved surface cushion block is difficult for wearing and tearing, the replacement cycle of moving contact combination is long, brings convenience to maintenance.
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 curved surface cushion block wear-resisting and lightweight, and overall structure is firm.
Brief description of the drawings
The utility model has following accompanying drawing:
Fig. 1 is the A-A view of Fig. 2.
Fig. 2 is the front view of curved surface cushion block,
Embodiment
Below by specific embodiment, the utility model is described in detail:
As shown in the figure, curved surface cushion block of the present utility model, for ball-crown body shape, formed by the spherical shell 1 on top and the ball-crown body 2 of bottom, 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 multiplely hold oily areola 4 and hold by multiple the runner 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 ball-crown body shape, formed by the spherical shell on top and the ball-crown body of bottom, spherical shell covers on ball-crown body, both junction planes are provided with and multiplely hold oily areola and hold by multiple 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.
