Description
Technical field
The utility model relates to a kind of guide rail, in particular to a kind of linear guide.
Background technique
Similar guide rail, traditional structure are dovetail configuration, and the gag for adjusting gap taper is adjusted, and gap is smaller, rubs
It is bigger to wipe power, and horizontal load is little；Linear bearing guide rail, poor seismic behavior, mechanical wear is fast, is hit, and is easy
Damage, unrepairable.
Utility model content
Technical problem to be solved in the utility model is in view of the deficiencies of the prior art, to provide a kind of linear guide.
To achieve the goals above, the measure that the utility model is taken:
A kind of linear guide, including connecting plate and linear guide ontology, it is opposite along its length on linear guide ontology
Two pieces of guide plates are provided with, the lower part of the connecting plate is fixed with a screw rod attachment base and two upper support adjustment axis, silk
The setting of bar attachment base is offered on screw rod attachment base and is set along linear guide body length direction between two upper support adjustment axis
The screw hole set, the both ends of upper support adjustment axis pass through upper bearing (metal) positioning screw and are equipped with U-shaped bearing, upper support adjustment axis
Lower part lower support adjustment axis is equipped with by lower adjusting bolt, the both ends of lower support adjustment axis are pacified by lower bearing positioning screw
U-shaped bearing is housed down, guide plate be clamped in upper U-shaped bearing and under between U-shaped bearing；
The screw rod attachment base is fixed on connecting plate by screw rodb base fixing bolt；
The upper support adjustment axis is fixed on connecting plate by upper support adjustment axis fixing bolt；
The both ends of the connecting plate pass through oil sealing screw and are fixed with oil sealing；
From top to bottom passing through in the upper support adjustment axis has locking screw, and the lower end of locking screw presses against lower support
In adjustment axis.
The utility model has the beneficial effects that practical, production cost is low, and structure novel, load capacity is strong, is hit, no
Easy to damage, parts damages can be replaced, and gap is adjustable, and vertical direction bearing capacity is strong, and way rub is small, be unlikely to deform,
Guide rail limit velocity is higher than conventional guide rails, and handling ease does not need special equipment auxiliary.
Detailed description of the invention
Fig. 1, the decomposition texture schematic diagram of the utility model.
Specific embodiment
A kind of linear guide, including connecting plate 1 and linear guide ontology 2, it is opposite along its length on linear guide ontology 2
Be provided with two pieces of guide plate 2-1, the lower part of the connecting plate 1 is fixed with a screw rod attachment base 3 and two upper supports are adjusted
Nodal axisn 4, the setting of screw rod attachment base 3 are offered on screw rod attachment base 3 between two upper support adjustment axis 4 along linear guide sheet
The screw hole of 2 length direction of body setting, the both ends of upper support adjustment axis 4 pass through upper bearing (metal) positioning screw 5 and are equipped with U-shaped axis
6 are held, the lower part of upper support adjustment axis 4 is equipped with lower support adjustment axis 8, the both ends of lower support adjustment axis 8 by lower adjusting bolt 7
U-shaped bearing 10 is installed down by lower bearing positioning screw 9, guide plate 2-1 be clamped in upper U-shaped bearing 6 under U-shaped bearing 10 it
Between.
The screw rod attachment base 3 is fixed on connecting plate 1 by screw rodb base fixing bolt 31.
The upper support adjustment axis 4 is fixed on connecting plate 1 by upper support adjustment axis fixing bolt 41.
The both ends of the connecting plate 1 pass through oil sealing screw 11 and are fixed with oil sealing 12.
From top to bottom passing through in the upper support adjustment axis 4 has locking screw 51, and the lower end of locking screw 51 presses against
In lower support adjustment axis 8.
Such as: the utility model use being used on lathe, screw rod passes through the screw rod on oil sealing 12 and screw rod attachment base 3
Hole.Upper U-shaped bearing 6 U-shaped bearing 10 under is moved along the length direction of guide plate 2-1.Realize the guiding purpose of linear guide.It is logical
Cross lower bearing positioning screw 9 and between upper bearing (metal) positioning screw 5 can adjusts down respectively between U-shaped bearing 10 and guide plate 2-1
Gap between gap, upper U-shaped bearing 6 and guide plate 2-1.Rotation is lower to adjust bolt 7, and adjustable upper support adjustment axis 4 is under
Support the gap between adjustment axis 8.The lower end of locking screw 51 presses against lower support adjustment axis 8, plays the role of locking, prevents
Lower adjusting bolt 7 loosens.Entire utility model load capacity is strong, is hit, is hardly damaged, and parts damages can be replaced,
Gap is adjustable, and vertical direction bearing capacity is strong, and way rub is small, is unlikely to deform.
