By describing in more detail the utility model referring to accompanying drawing, can understand better principle of the present utility model, feature and advantage below.Accompanying drawing comprises:
Fig. 1 shows the perspective view of the biopsy cavity marker devices of an exemplary embodiment of staggered form roller guide mechanism.
Fig. 2 shows the course of work of certain circle circulation roller.
The specific embodiment
, will specific embodiment of the utility model be described in more detail referring to accompanying drawing below, to understand better basic thought of the present utility model.
Fig. 1 shows the perspective view of the biopsy cavity marker devices of an exemplary embodiment of staggered form roller guide mechanism.
Two end caps 4 at the slide block 3 that as shown in Figure 1, staggered form roller guide mechanism 1 comprises guide rail 2, is arranged on guide rail 2 and can moves back and forth along guide rail 2, the two ends that are fixed on slide block 3 and be preferably arranged on slide block 3 and end cap 4 roller mechanism 5 in both.
Preferably, in order further to reduce force of rolling friction, be preferably provided with for the oil nozzle 6 to roller mechanism 5 feed lubricating oil at end cap 4 places.
As shown in Figure 1, it is trapezoidal groove 7 that the both sides of guide rail 2 have corresponding cross section, and slide block 3 rides on guide rail 2 and has the structure of stretching to groove 7.Preferably, be equipped with roller mechanism 5 at groove 7 places of guide rail 2 both sides.
As shown in Figure 1, slide block 3 and end cap 4 have been exposed a part for the roller mechanism 5 of a side by biopsy cavity marker devices.Below, be example detailed description by the roller mechanism take this side 5.
Groove 7 has the first inclined-plane 10, the second inclined-plane 11 and the vertical plane 12 between the first inclined-plane 10, the second inclined-plane 11.The second circle circulation roller 14 that roller mechanism 5 has the first lap circulation roller 13 rolling on the first inclined-plane 10 and rolls on the second inclined-plane 11.The circulating rolling plane of first lap circulation roller 13 preferably with the circulating rolling planar quadrature of the second circle circulation roller 14.
To the course of work of certain circle circulation roller be described referring to Fig. 2 below.Fig. 2 shows the front view of this circle circulation roller.
As shown in Figure 2, this circle circulation roller comprises multiple rollers 15, and each roller 15 rolls along circulating path 16 successively, and a side of the Part I 17 of circulating path 16 is by the specifically corresponding contact inclined-plane on guide rail 2 of guide rail 2() gauge.The Part II 18 of circulating path 16 is formed in slide block 3, the remainder 19 of circulating path 16, especially makes the part of roller 15 backs be formed in the end cap 4 being connected with slide block 3.Therefore, end cap 4 not only plays sealing process at this, makes roller 15 backs so that back structure that can circulating rolling but also be provided with.
It will be obvious to those skilled in the art that, circulating path 16 also can be configured in slide block 3 completely.
Under normal circumstances, when slide block 3 is when together with end cap 4, along guide rail 2, to the right or left (as shown by the arrows in Figure 2) is mobile, each roller 15 rolls along circulating path 16, with guide rail 2(specifically with the first inclined-plane 10 or second inclined-plane 11 of guide rail 2) those rollers 15 of contacting roll on guide rail 2,, slide block 3 moves with respect to guide rail 2 together with end cap 4.
But, as mentioned above, at roller 15 because a variety of causes can not roll swimmingly, particularly stuck in the situation that, if now force moving slider 3, may cause the further damage of roller 15 and/or guide rail 2.
For this reason, according to the utility model, be respectively every circle circulation roller arrange a sensor 20 survey its motion, as shown in Figure 2.
In the time that slide block 3 moves, the rolling, particularly stuck as long as having some setbacks appears in any one roller in any circle circulation roller, will make the roller in this circle circulation roller roll appearance extremely.Owing to being provided with corresponding sensor 20, this can detect by this sensor 20 extremely.
For signal that can analyzing and processing sensor 20, processor (not shown) is also provided, the signal of each sensor is sent to described processor.
According to a preferred embodiment, for the sensor 20 of every circle circulation roller setting can be inductosyn, for example, approach switch.If this inductosyn is arranged on close to roller by the side of roller, in the time that each roller rolls through this sensor successively, the beeline between sensor and the face of cylinder of roller can produce rule and change.; when a roller is during just to this sensor, this roller of this sensor distance is nearest, along with this roller is away from this sensor; distance between this sensor and this roller is increasing; when the position between two adjacent rollers and this sensor just to time, sensor distance roller farthest, in the time that next roller rolls towards this sensor; this distance can diminish again gradually; until this next one roller is during just to this sensor, it is minimum that distance reaches again, then circulation successively.
Therefore,, in the time that roller normally rolls, corresponding sensor can produce strong signal and weak signal (or zero-signal) alternately.In the time of roller uniform roll, corresponding sensor can produce cyclical signal.When roller have some setbacks rolling, when particularly stuck, this characteristic of signal can change.For example, in the time that any one roller in certain circle circulation roller is stuck, if corresponding sensor just in time faces toward a roller, sensor can produce strong signal always, if corresponding sensor is just in time facing to the position between two adjacent rollers, sensor can produce weak signal always.Therefore,, by analyzing and processing sensor signal, can know the motion state of roller.
Through above analyze known, for the sensor 20 of every circle circulation roller setting can be the sensor of any type, as long as can detect whether proper motion of roller.For example,, according to a preferred embodiment, for the sensor 20 of every circle circulation roller setting can be also range sensor, for example ultrasonic distance sensor.But consider the working environment of roller, preferably adopt above-mentioned inductosyn.
According to a preferred embodiment, also can survey its motion for slide block 3 arranges a sensor.Like this, as long as detect slide block 3, moving, certain encloses not proper motion of circulation roller, and processor just can for example provide warning by warning device.
Also can judge whether by respectively enclosing the signal of sensor of circulation roller that roller of certain circle circulation roller is stuck.For example, as long as sensor is judged the circulation roller proper motion of corresponding circle, just can judge that slide block 3 is moving, so just can judge the whether proper motion of circulation roller of other circles.
For the sensor 20 of every circle circulation roller setting can be arranged on any suitable position, as long as this sensor can detect the motion of this circle circulation roller.For example, can be by sensor setting on slide block 3 or on end cap 4.Now, preferably on slide block 3 or end cap 4, process installing hole, then corresponding sensor is put into this installing hole, and preferably with encapsulant, this sensor is sealed.This installation method does not need to change the basic structure of roller guide mechanism, and the process relating to and assembling process are also very simple.
In addition, for a person skilled in the art, in the time adopting ball to replace roller, technique scheme is still feasible.
Obviously, for a person skilled in the art, technique scheme also can be applied to any guide rail mechanism that comprises at least one circle circulation roller.In the time only thering is a circle circulation roller, a sensor need to be set simultaneously detect the motion of slide block.
Basic thought of the present utility model is, surveys whether proper motion of every circle circulation roller or ball by sensor is set, and can judge whether roller or ball are stuck.This provides a kind of whether stuck method of roller or ball that detects simply, reliably.Stuck by finding in time, can take measures as soon as possible to avoid further damage.
It will be obvious to those skilled in the art that, technique scheme also can be applicable to any guide rail mechanism of the rolling element that comprises acyclic layout in a row.
For a person skilled in the art, other advantages of the present utility model and substituting embodiment are apparent.Therefore, the utility model with regard to its more wide in range meaning, be not limited to shown in and described detail, representative configurations and exemplary embodiment.On the contrary, those skilled in the art can carry out various modifications and substitute in the situation that not departing from essence spirit of the present utility model and scope.
