Description
One, technical field
The utility model relates to a kind of guiding pairs that is used for numerical control machine tool, specifically a kind of cage type retainer of roller crossing linear guide pairs.
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.Wherein, the rolling cross linear guides pair generally is made up of V-way, slide block, roller, retainer.Motion principle is that roller intersects to roll in the raceway of two V-ways and realizes rolling the straight line motion of cross linear guides pair.For avoiding being in contact with one another between two rollers, it is separated with retainer.Along with the continuous development of machine industry, the numerical control machine tool that develops low noise, long-life, high response speed, high reliability under the prerequisite that does not reduce function of use is the main development trend of current machine industry.In order to adapt to machine industry, especially the development of application such as surveying instrument, bearing groove processing grinding machine is to the requirement of rolling function parts product, and existing foil structures retainer can not meet the demands.
Existing retainer is a foil structures, see accompanying drawing 1, its principle is to utilize kidney slot 21 being arranged on the base plate 1 and inner chamber two ends to prop up mouthfuls 22 fixing rollers 3, a 90 degree mouth 22 of retainer must be pulled back 45 and spend just fixedly roller 3 when the dress roller, installing a retainer assembly like this needs the long time.The sheet metal retainer generally adopts drawing in addition, and the precision of drawing is relatively poor, and stamping surface can residual tiny burr, and the stamping surface contact surface of roller 3 and retainer just, the friction factor between roller and the retainer will be very big like this; In addition, in the whole retainer assembly if there is a kidney slot to be processed with problem, whole guide rail will occur during to operation because of friction between guide rail, roller and retainer cause motion not freely, a series of adverse consequencess such as noise rising.
Three, summary of the invention
In order to adapt to machine industry, especially the development of application such as surveying instrument, bearing groove processing grinding machine is to the requirement of rolling function parts product, overcome the shortcoming of existing sheet metal retainer, the purpose of this utility model provides a kind of cage type retainer of roller crossing linear guide pairs, this retainer dimensional accuracy height, easy for installation, noise is little, the life-span is long.
The purpose of this utility model is achieved through the following technical solutions:
A kind of cage type retainer of roller crossing linear guide pairs, it is characterized in that: it is made up of one group of identical single cage body head and the tail interconnection that is made of plastics, the relative bi-side of described cage body are provided with the opening that the cylindrical side that makes roller stretches out, and are provided with at opening and are used for preventing the blocked ear that roller skids off; The inner cavity size of described cage body is greater than the roller body diameter; End at single cage body is provided with attachment hole, and the other end is provided with the grab suitable with attachment hole; Adjacent two cage bodies interconnect and rotatable cooperation by attachment hole and grab.
In the utility model, the shape of described blocked ear and the cylndrical surface of roller are suitable.Blocked ear is also made by plastic materials, and blocked ear has 45 degree inclined-planes, and the inner cavity size of cage body is greater than the roller body diameter; Size between opening blocked ear and corresponding opening edge is less than the roller body diameter.During installation, utilize the resiliently deformable of plastics blocked ear that roller gently is pressed in the chamber, block the roller cylinder by 45 degree inclined-planes again, thereby simplified the installation of roller and retainer, improve efficiency of assembling.
For reducing wearing and tearing, in the inner chamber of cage body and the formed gap of roller, be provided with the lubricant oil that is used for to the roller sufficient lubrication.
The utility model adopts plastic materials to be shaped by Mold Making, has improved dimensional accuracy effectively and has improved the roughness of surface of contact, greatly reduces the friction factor between roller and retainer; Simultaneously, because being the mode with end-to-end, retainer described in the utility model links together, repair simple and convenient, when wherein a cage body damages, the cage body that breaks down can be taken off, reconnect an intact cage body, whole like this retainer can continue again to have used.
Compare with existing guiding pairs sheet metal retainer, the utility model has the advantages that: 1, maintenance, replacing are conveniently.2, roller is easy for installation, efficient is high.3, good manufacturability adopts plastic mould processing, has higher dimensional accuracy than the metal retainer that strikes out shape.4, high-performance, the stagnant phenomenon of nothing in service has improved speed of response; 5, high lubricating effect, the less amount of lubrication oil of can attracting deposit is carried out selflubricating; 6, energy-conservation, reduce greatly between retainer and roller and wear and tear, prolonged the life-span of retainer and cross-roller guide pair effectively.7, noise is little, has protected environment.
The utility model is applicable in all roller crossing linear guide pairss.

Five, embodiment
A kind of cage type retainer of roller crossing linear guide pairs described in the utility model, it is made up of the 2 head and the tail interconnections of one group of identical single cage body that is made of plastics, the relative bi-side of cage body 2 are provided with the opening 5 that the cylindrical side that makes roller 3 stretches out, and are provided with at opening 5 places and are used for preventing the blocked ear 4 that roller 3 skids off; The inner cavity size of cage body 2 is greater than roller 3 body diameters; End at single cage body 2 is provided with attachment hole 6, and the other end is provided with the grab 7 suitable with attachment hole 6; Adjacent two cage bodies interconnect and rotatable cooperation by attachment hole 6 and grab 7.The rear and front end face of cage body 2 is a square, and adjacent two cage bodies 2 can revolve and turn 90 degrees into cross arrangement after attachment hole 6 was connected with grab 7.
The cylndrical surface of the shape of blocked ear 4 and roller 3 is suitable.Blocked ear 4 is also made by plastic materials, and blocked ear 4 has 45 degree inclined-planes, and the inner cavity size of cage body 2 is greater than roller 3 body diameters; Size between opening blocked ear 4 and corresponding opening edge is less than roller 3 body diameters.
During installation, the resiliently deformable of utilizing plastics blocked ear 4 gently is pressed into the inner chamber of cage body 2 with roller 3, and 45 degree inclined-planes by blocked ear 4 block roller 3 cylinders again, prevent that roller 3 from skidding off.Single cage body 2 is connected with grab 7 by attachment hole 6 interconnects, and adjacent two cage bodies 2 revolve and turn 90 degrees the back and become cross arrangement.Thereby simplified the installation of roller and retainer, improved efficiency of assembling.Simultaneously, be provided with the lubricant oil that is used for to roller 3 sufficient lubrications in the inner chamber of cage body 2 and roller 3 formed gaps 8, a small amount of oil mass just can be given the roller sufficient lubrication.
Retainer described in the utility model just wraps in inside with roller dexterously as cage, see Fig. 3, it is made up of one group of the first interconnection of several same cage body, and is easy to process, and the length of retainer can be adjusted arbitrarily, satisfies various needs.And repair simple and conveniently, and when breaking down wherein a cage body, we can take off the cage body that breaks down, and have reconnected good cage body, and whole like this retainer just can continue to have used again.
