Abstract
The utility model discloses a prevent linear guide of card pearl, include: the guide rail, the slider of setting on the guide rail, the ball slot is constituteed jointly to the clinostat at the passageway sum channel both ends that correspond on the inside passageway that supplies a plurality of balls to pass through that is provided with of slider, passageway and guide rail, and the ball setting is in the inside and inseparable range of slot, the rectangle through -hole that the centre was seted up on the clinostat lateral wall, the wheel of stirring corresponding to the through -hole setting. The utility model provides a ball can be died at the slot inside callipers among the prior art to cause the technical problem that the slider can not normally work.
Description
Technical field
The utility model relates to processor field, in particular to a kind of line slideway preventing card bead.
Background technology
Line slideway is used for straight reciprocating motion occasion, has the rated load higher than linear bearings, can undertake certain moment of torsion simultaneously, can realize the translational motion of high precision in high-load situations, this. Line slideway is the same with plane guide rail, has two primary elements; One is retaining element as what lead, and another is mobile element. Without intermediate medium between the mobile element of line slideway and retaining element, and by rolling steel balls, it is called for short ball. Can also be interpreted as it is a kind of guiding of rolling, it is circulate with infinite scroll between guide rail at slide block by ball, thus make load platform along guide rail easily high-precision linear move, and frictional coefficient is down to tradition slide guiding 1/50th, very high positioning precision can be reached easily.
When the movement velocity of slide block is too fast, ball generation spot corrosion or break, the distortion of ball groove, the situation generation such as ball is bonding with groove, lubricant is under-supply time, ball can be stuck in groove, thus cause slide block can not normal operation, affect location and the following process of follow-up slide block.
Practical novel content
The utility model object is to provide a kind of line slideway preventing card bead, solves in prior art that ball can be stuck in groove, thus causes the slide block can not the technical problem of normal operation.
The technical solution of the utility model is, a kind of line slideway preventing card bead, comprising:
Guide rail;
The slide block being arranged on guide rail;
Slide block inside is provided with for the passage that some balls pass through, and the gyrator at the passage that passage is corresponding with on guide rail and passage two ends forms ball groove jointly, and ball is arranged on groove inside and close-packed arrays;
Gyrator outer side wall hits exactly the rectangular through holes offered;
Corresponding to the turning wheel that through hole is arranged, turning wheel is arranged on the slideway offered slide block inside, turning wheel can be slided by hinged part on slideway, the circle centre position of turning wheel is fixedly connected with spring, and the other end of spring is connected with slide block, when turning wheel is not by external force, the elastic force of turning wheel dependence spring is close on slideway away from one end of gyrator, when the external force that turning wheel is subject to is greater than the elastic force of spring, a part for turning wheel can contact through through hole with ball, and provides external force to ball.
Further, the edge of turning wheel is provided with rubber circle.
Further, gyrator place arranges 1 turning wheel respectively.
Further, the diameter of turning wheel is 2 times of ball diameter.
Further, 2 times of through hole to be length be ball diameter, width is the 1/4 of ball diameter.
The utility model provides a kind of line slideway preventing card bead, through hole is offered and correspondence arranges turning wheel at gyrator, apply an external force by turning wheel to ball when card bead, thus offset the squeeze between ball, make the ball in groove again be in state smoothly. The utility model is possible not only to the problem solving card bead when not taking slide block apart, moreover it is possible to effectively extend the work-ing life of slide block.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of line slideway preventing card bead in the utility model;
Fig. 2 is the sectional view in A-A direction in Fig. 1.
Embodiment
As shown in Figure 1-2, a kind of line slideway preventing card bead, comprising:
Guide rail 9;
Slide block 1 on the rail 9 is set;
Slide block 1 inside is provided with for the passage that some balls 3 pass through, and the gyrator 10 at the passage that passage is corresponding with on guide rail and passage two ends forms ball groove 2 jointly, and ball 3 is arranged on groove 2 inside and close-packed arrays;
Gyrator 10 outer side wall hits exactly the rectangular through holes 4 offered;
Corresponding to the turning wheel 8 that through hole 4 is arranged, turning wheel 8 is arranged on the slideway 5 offered slide block inside, turning wheel 8 can be slided by hinged part 7 on slideway 5, the circle centre position of turning wheel 8 is fixedly connected with spring, the other end of spring is connected with slide block, when turning wheel 8 is not by external force, turning wheel 8 relies on one end that the elastic force of spring is close on slideway 5 away from gyrator 10, when the external force that turning wheel 8 is subject to is greater than the elastic force of spring, a part for turning wheel 8 can contact through through hole 4 with ball 3, and provides external force to ball 3.
Further, the edge of turning wheel 8 is provided with rubber circle 6. Gyrator 10 place arranges 1 turning wheel 8 respectively. The diameter of turning wheel 8 is 2 times of ball 3 diameter. 2 times of through hole 4 to be length be ball 3 diameter, width is the 1/4 of ball 3 diameter.
When ball 3 card bead in slide block, it may also be useful to person can pin turning wheel 8, turning wheel 8 is contacted with ball 3 through through hole 4, then positive and negative rotation turning wheel 8, thus make ball 3 be in standard state. It is noted that in order to prevent the impurity such as dust from entering groove, do not use the box of the fit should being used for during turning wheel to seal.
The utility model provides a kind of line slideway preventing card bead, through hole is offered and correspondence arranges turning wheel at gyrator, apply an external force by turning wheel to ball when card bead, thus offset the squeeze between ball, make the ball in groove again be in state smoothly. The utility model is possible not only to the problem solving card bead when not taking slide block apart, moreover it is possible to effectively extend the work-ing life of slide block.
Above; it is only embodiment of the present utility model; but protection domain of the present utility model is not limited thereto; any it is familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model. Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
