Compared with the existing rolling linear guiding rail pair, the utility model has the advantages of large bearing capability, good guidance performance, stable running, low noise and long service life. The utility model can be widely suitable for machine tools having high requirements for bearing capacity and low requirements for noise.
Description
One, technical field
The utility model relates to a kind of guiding device that is used for numerical control machine tool, specifically a kind of roller line slideway auxiliary.
Two, background technique
At present, linear rolling guide generally is made up of guide rail, slide block, steel ball, back device, retainer etc.Its working principle is to roll in the raceway of guide rail and slide block formation by steel ball, realizes the straight line motion of linear rolling guide.Along with the continuous development of machine industry, little, in light weight, the low noise of development volume, lathe that bearing capacity is strong are the trend of current machine industry development under the prerequisite that does not reduce function of use.The shortcoming of the linear rolling guide that the employing steel ball is made is: 1, bearing capacity is little; 2, the guidance quality of steel ball is poor in the raceway, moves not steady; 3, the operation noise is big, and working life is short.
Three, summary of the invention
The purpose of this utility model provides a kind of roller line slideway auxiliary, and this guiding pairs has overcome the shortcoming of original linear rolling guide, in bearing capacity, and installation dimension, working life, there was bigger advantage the aspect.
The purpose of this utility model is achieved through the following technical solutions:
A kind of roller line slideway auxiliary, it is characterized in that: it comprises guide rail, slide block, roller, isolation chain, back device and retainer, on slide block, be provided with and the suitable groove of the sectional shape of guide rail, roller is arranged in the isolation chain and is installed between the both sides and guide rail of groove, slide block is arranged on the guide rail by roller and can moves axially along guide rail, the back device that is used for roller is turned to is fixed on the two ends of slide block, and slide block and back device are fixed by retainer.
In the utility model, for roller is operated steadily between guide rail and slide block, the surface of contact of the cylinder of roller and guide rail and slide block is suitable, roller is line with guide rail and slide block and contacts, wrapping angle is 45 °, every row roller all bears axial force and radial force, has guaranteed that the four directions to waiting carrying property, makes that bearing capacity is 200% of an identical appearance size steel ball guiding pairs.
The stream ball hole employing that is arranged in the utility model in the slide block is suitable with roller, and the square groove structure that guidance quality is good has guaranteed the smooth running of roller in stream ball hole.
The utility model is provided with the back baffle plate between guide rail and slide block, guaranteed to isolate the good back of chain, and electricity has guaranteed the good guidance of roller in raceway.Roller is provided with lubricating grease with isolating interchain, forms the lubricating grease storage area, and the life-span is lasting; Adopt zero contact between roller, it is low to wear and tear, and noise is little.Isolate chain and adopt high abrasion resisting material, stable performance.
The utility model is respectively equipped with two rows and isolates chain and rollers between the both sides of groove and guide rail.Motion principle is that roller rolling in the raceway of guide rail and slide block formation realizes carrying straight line motion.The utility model employing roller has substituted the steel ball in original linear rolling guide, stream ball hole in the slide block is adopted with roller suitable simultaneously, the square groove structure that guidance quality is good, compare with existing linear rolling guide, the utility model has the advantages that: be that 45 ° of lines contact stressed between the roller of roller guide pair and raceway 1,, guaranteed the four directions to waiting carrying property, bearing capacity is big; 2, adopt and the suitable square groove structure of roller in the stream ball hole in the slide block, and guidance quality is good, simultaneously, is provided with the back baffle plate between guide rail and slide block, has guaranteed to isolate the good back of chain, has also guaranteed the good guidance of roller in raceway, thereby operated steadily; 3, roller and isolation interchain form the lubricating grease storage area, and the life-span is lasting, adopt zero contact between roller, and it is low to wear and tear, and noise is little, stable performance.
