Description
Technical field
The utility model is related to guide sleeve technical fields, and in particular to a kind of Self-lubricating ball guide sleeve.
Background technology
Guide sleeve is dieparts, is used cooperatively with guide post, and a guiding, general fit clearance very little are played the role of；One
As be mostly used in mold or some machineries, come ensure movement accuracy.
Existing guide sleeve needs to be maintained by worker's timing addition lubricating oil in use, very inconvenient,
And the effect of the manual application of lubricant is bad, and the service life of guide sleeve is caused not grown, and the inner surface and guide post appearance of common guide sleeve
Face completely attaches to, and further shortens the service life of guide sleeve.
Utility model content
Above-mentioned to solve the problems, such as, the utility model provides following technical scheme.
The utility model provides a kind of Self-lubricating ball guide sleeve, including guide sleeve shell, the guide sleeve shell upper have flange,
It is provided with an oil groove on the flange, a corresponding oil groove cover plate is provided on oil groove；It is provided on guide sleeve outer casing inner wall several
Ball grooves, for placing ball set；The ball grooves upper end connects with oil groove, and is equipped with a through-hole in the joint, is worth
It is noted that the ball of the top can just block the through-hole and normally rotate in ball grooves；It is set in the guide sleeve shell
It is equipped with retainer, ball set is limited in ball grooves by retainer, makes it that can only rotate, and ensure that the precision of guiding.
An oil filler point is provided on the oil groove cover plate, the oil filler point includes steel ball, spring and a hole with convex block, institute
It states lower spring end to be against on convex block, upper end is provided with a steel ball, and under the elastic force effect of spring, steel ball just blocks hole.
Further scheme as the utility model：It is connected through a screw thread between the oil groove cover plate and oil groove.
Further scheme as the utility model：It is provided with rubber seal on the contact surface of the oil groove cover plate and oil groove
Circle.
Further scheme as the utility model：The centerline axis parallel of the ball grooves and guide sleeve shell.
Further scheme as the utility model：The length of the ball grooves can just put down several balls.
Further scheme as the utility model：The ball groove depth is equal to the radius of ball.
The beneficial effects of the utility model：When in use, first lubricating oil is injected into oil groove, the mobile drive ball of guide post turns
Dynamic, the ball of ball set the top is exported by rotating lubricating oil out of oil groove, is lubricated, more more convenient than the manual application of lubricant
Fast, and lubricant effect is more preferable；Because having used ball set, the contact surface of guide sleeve and guide post is fallen below into minimum,
Considerably increase the service life of guide sleeve.
Description of the drawings
Fig. 1 is a kind of structural schematic diagram of Self-lubricating ball guide sleeve of the utility model.
Fig. 2 is the enlarged drawing at A in Fig. 1.
Specific implementation mode
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only explaining this
Utility model is not used to limit the utility model.
As shown in Figure 1, a kind of Self-lubricating ball guide sleeve, including guide sleeve shell 1, ball set 2, oil groove cover plate 3, oil groove 4, guarantor
Flange is arranged at holder 5, steel ball 6 and spring 7,1 top of guide sleeve shell, when in use, flange can increase guide sleeve and mold it
Between cooperation precision；It is provided with an oil groove 4 on the flange, a corresponding oil groove cover plate 3, oil groove cover plate 3 are provided on oil groove 4
It is connected through a screw thread between oil groove 4, and rubber seal is provided on the contact surface of oil groove cover plate 3 and oil groove 4, prevented
The leakage of fluid；Several ball grooves parallel with axis are provided on 1 inner wall of guide sleeve shell, for placing ball set 2, the rolling
The length of pearl slot can just put down several balls；The ball grooves upper end connects with oil groove 4, and is equipped in the joint
One through-hole, it is notable that the ball of ball grooves the top can just block the through-hole and normally rotate；The guide sleeve
Retainer 5 is provided in shell 1, ball set 2 is limited in ball grooves by retainer 5, is made it that can only rotate, be ensure that
The precision of guiding.
As shown in Fig. 2, being provided with an oil filler point on the oil groove cover plate 3, the oil filler point includes steel ball 6, spring 7 and one
Hole with convex block.7 lower end of the spring is against on convex block, and upper end is provided with a steel ball 6, under the elastic force effect of spring 7, steel ball
6 just block hole.
Specific embodiment of the utility model one：Steel ball 6 is depressed, lubricating oil is injected into oil groove 4, when guide post moves up and down
Ball set 2 is driven to rotate together, the ball of the top takes the lubricating oil in oil groove 4 out of by rotating, and is lubricated.And lead to
It crosses and uses ball, the contact surface of guide sleeve and guide post is fallen below into minimum, the service life of guide sleeve and guide post is made to greatly increase.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Any modification, equivalent replacement or improvement etc., should be included in the utility model made by within the spirit and principle of utility model
Protection domain within.
