Abstract
The utility model relates to a machine tool needle roller linear guide rail pair comprising a guide rail, a sliding base and a support rolling body disposed between the guide rail and the sliding base. The support rolling body is constituted by a plurality of needle rollers, a left support roller and a right support roller. The upper and lower surface of the sliding base are respectively provided with a needle roller guide groove along the axial direction, and the needle rollers are disposed in the guide grooves. The left support roller and the right support roller, which are disposed between the guide rail and the sliding base, and the guide rail are disposed at an angle of 45 DEG. The utility model is advantageous in that the needle rollers are in a close-packed arrangement, and are connected together through nylon retainers, thereby the connection is stable and has low noise, meanwhile the guiding performance can be used to guarantee that the needle roller can return to the return groove successfully; the wearing loss of the needle rollers and the sliding base are small, the installation is easy and has interchangeability; the lubrication condition is good and the service lifetime is long; the contact rigidity of the sliding base, the rolling body and the guide rail can be improved, the bearing capacity can be greatly improved, thereby the utility model can satisfy the requirements of the numerical control machine tool and the product of mechanical and electrical integration such as the good rigidity and good bearing capacity.
Description
Technical field
The utility model belongs to lathe, relates in particular to a kind of lathe needle roller line slideway auxiliary
Background technology
Usually adopt the ball line slideway auxiliary in the present mechanical industry.As Fig. 4, shown in Figure 5, its structure is: slide and guide rail respectively have four arc raceways, pass through ball bearing between it.Only rely on the interior ball of slide as the supporting rolling element, ball is the some contact with contacting of guide pass.Advantage is that frictional force is little, sensitivity and precision height, is suitable for the miniature precision lathe and uses.Shortcoming is that the contact rigidity is relatively poor, and bearing capacity is little, and the corresponding wearing and tearing of the friction between ball and the raceway are very fast.Can not satisfy the needs of the product of large-size numerical control machine and electromechanical integration.
The utility model content
The purpose of this utility model is to overcome the deficiency of above-mentioned technology, and provide a kind of lathe needle roller line slideway auxiliary, improved slide, contact rigidity between rolling element and the guide rail three, rolling element has replaced ball by needle roller, roller, improve bearing capacity widely, be more suitable for requiring the needs of the product of big Digit Control Machine Tool of good rigidly, bearing capacity and electromechanical integration.
The utility model for achieving the above object, by the following technical solutions: a kind of lathe needle roller line slideway auxiliary, comprise guide rail and slide and between the supporting rolling element, it is characterized in that: described supporting rolling element is made of some needle rollers and left supporting roller and right supporting roller, described slide upper and lower surface is provided with the needle roller guide groove vertically, and described needle roller places guide groove; Describedly place left supporting roller between guide rail and the slide and right supporting roller and guide rail to be 45 ° to be slidingly connected.
Described needle roller is the solid matter formula, connects by the nylon retainer between the needle roller.
Be provided with the nylon retainer between described left supporting roller and the right supporting roller.
Beneficial effect: needle roller belongs to the solid matter formula, and is middle by the connection of nylon retainer, can guarantee that connection is steady, noise is little, has good guided bone simultaneously, and needle roller turns back in the kick backs smoothly; Needle roller rolls on guide rail smoothly simultaneously.Adopt left and right sides supporting roller to contact cooperation with at 45 intersection of guide rail.Through debugging, can make it bear the active force of each side up and down.The attrition of needle roller, slide is very little; Assembling is easy, and has interchangeability; Lubricating condition is good, long service life.Improved slide, the contact rigidity between rolling element and the guide rail three, rolling element has replaced ball by needle roller, roller, has improved bearing capacity widely, has been more suitable for requiring the needs of the product of big Digit Control Machine Tool of good rigidly, bearing capacity and electromechanical integration.

The specific embodiment
Describe the specific embodiment of the present utility model in detail below in conjunction with accompanying drawing and preferred embodiment.As shown in the figure, a kind of lathe needle roller line slideway auxiliary, comprise guide rail 1 and slide 2 and between the supporting rolling element, described supporting rolling element is made of some needle rollers 3 and left supporting roller 4 and right supporting roller 5, described slide upper and lower surface is provided with needle roller guide groove 6 vertically, and described needle roller places guide groove; Describedly place left supporting roller between guide rail and the slide and right supporting roller and guide rail to be 45 ° to be slidingly connected.Described needle roller is the solid matter formula, connects by nylon retainer 7 between the needle roller.Be provided with the nylon retainer between described left supporting roller and the right supporting roller.
Needle roller belongs to the solid matter formula, and is middle by the connection of nylon retainer, can guarantee that connection is steady, noise is little, and the needle roller guide groove has good guided bone, can make needle roller turn back in the guide groove smoothly; Needle roller rolls on guide rail smoothly.Adopt left and right sides supporting roller to contact cooperation, play the effect of traditional slide rail " clamp bar " with at 45 intersection of guide rail.Through debugging, can make it bear the active force of each side up and down, can regulate in production process and reach optimum state, implement fixing again.Cooperatively interact between needle roller and the roller, can make it bear the active force of each side up and down.
The above only is preferred embodiment of the present utility model, is not structure of the present utility model is done any pro forma restriction.Every foundation technical spirit of the present utility model all still belongs in the scope of the technical solution of the utility model any simple modification, equivalent variations and modification that above embodiment did.
