Definitions
- the invention relates to a position detector of a moving part. likely to actuate a button on the detector. More precisely the invention discloses a mechanism for orienting the pusher of the detector.
- a position detector is a device intended to be actuated by a moving part, either due to the shape of its pusher, or due to the effort necessary for its action.
- the position of the moving part is detected by the mechanical action that the part exerts on the pusher when it is in contact with the latter.
- Position sensors are usually equipped with microswitches combining a reliable abrupt switching system with a sealed enclosure surrounding a gas atmosphere around the contacts neutral suitable for switching low level circuits to currents high.
- the movement of the pusher by the moving part activates the microswitch producing the closing or opening of an electrical contact signaling the presence of the moving part.
- the shape of the part of the pusher coming into contact with the part mobile is adapted on the one hand, to the shape of the mobile part which wishes to detect the position, and on the other hand to the type of movement of the room.
- the angle of attack defined between the direction the movement of the moving part and the axis of the pusher, upon contact with the moving part with the pusher can be different.
- the free end of the pusher in the case of moving the moving part, in the direction of the axis of the pusher, can be simply a semi-spherical surface ensuring a point contact with the moving part.
- the free end of the pusher can be fitted with a ball that can pivot in the pusher so to ensure frictionless contact with the mechanical part, when this the latter has lateral movements relative to the axis of the pusher.
- the moving part moves in a movement linear substantially perpendicular to the axis of the pusher
- the latter has at its free end a roller oriented in the direction of movement of the part, the roller being integral with the pusher and capable of turn around an axis of rotation perpendicular to the axis of the pusher.
- Figure 1a shows a partial section of a detector position 10 according to the prior art, comprising a roller 12, a guide 14 rotatable around a first axis XX 'of rotation, in a body 16 and a pusher 18 sliding without rotation in the guide 14 along this first axis XX '.
- the pusher has at its free end the roller 12 of shape cylindrical circular, rotatable by means of a shaft 20 around a second axis YY 'of rotation, this second axis YY' being collinear with the axis of revolution of the roller, and perpendicular to the first axis XX '.
- a first force F1 is then exerted by the moving part P on the periphery of the roller.
- This first F1 force transmitted to the pusher 18 via the shaft 20 produces a force component F2 in the direction of the first axis XX '.
- This F2 component slides the pusher 18 in the guide 14, and the roller 12 in two grooves guide 22 of guide 14, located on either side of the first axis XX '.
- a return spring 28 is located compressed during movement of the pusher towards the interior of the body. When the moving part P moves away from the roller, the pusher 18 regains its initial position pushed back by the return spring 28.
- the body 16 of the position detector is fixed on a frame (not shown in Figure 1a) thus being immobilized in position by relative to the direction of movement of the moving part.
- the roller 12 must be able to be oriented and kept in position angular around the first axis XX 'so that the second axis YY', around which the roller turns, is substantially perpendicular to the direction Dz of the movement of the moving part whose position.
- the orientation of the roller in the direction of movement of the workpiece mobile ensures optimal roll of the roller on its shaft avoiding lateral forces during contact with the moving part.
- the guide 14 has at its lower part of the position grooves 30 distributed at its periphery at an angular pitch ⁇ around the first axis XX '.
- the detector includes a positioner 32 located at the upper part of the body 16, fixed in rotation in the body of the detector, in the form of a washer comprising a lug 34 intended to penetrate one of the position grooves 30.
- the body has a thread 35 on its cylindrical surface outer allowing to screw a nut 36 making tightening the guide 14 and the positioner 34 secured to the body 16.
- Figure 1b shows a perspective view of guide 14 showing the position grooves 30 distributed at the periphery of the guide at a pitch angular ⁇ of 45 degrees.
- FIG. 1c shows a simplified top view according to AA 'of the detector, for an angular positioning ⁇ substantially equal to 90 degrees of the guide grooves 22 relative to the axis of reference ZZ '.
- ⁇ substantially equal to 90 degrees of the guide grooves 22 relative to the axis of reference ZZ '.
- the second axis YY 'of the roller 12 shown in dotted lines in FIG. 1c will have turned by the angle ⁇ equal to 90 degrees from its position in Figure 1a.
- Figure 2a shows a principle view of a position 40 according to the prior art showing another mechanism for angular positioning of a pusher 42 relative to a fixed body 44 of the detector.
- the position detector 40 comprises, as in the case of the detector of Figure 1a, a guide 46 rotatable around the first axis XX 'in the body 44, the pusher 42 sliding without rotation in the guide 46 along this first axis XX '.
- the guide 46 has first holes 48 distributed radially along the angular step ⁇ around the first axis XX ', the axes of the holes being located in the same plane perpendicular to the first axis XX ', each of the holes 48 being able to be brought into alignment with a second hole 50 opening at the periphery of the body 44.
- Figure 2b shows the collar 52 comprising in its part central a small rod 54 that can be inserted into the second hole 50 of the body and in one of the first holes 48 of the guide located in the extension from the first.
- the choice of one of the second holes 48 maintained in the extension of the first hole by the rod 54 ensures positioning angularly ⁇ of the guide relative to the body of the detector.
- the detector in operation, is subjected to shocks during contacts between the moving part and the roller. These repetitive shocks produce vibrations of the detector with the risk of unlocking the positioner of the detector body. These vibrations can produce for example the escape of the collar 52 of the detector of FIG. 2a or the loosening of the nut 36 of the detector of FIG. 1a.
- the or the tongues are capable of being folded to allow the introduction of minus one tab in a guide position groove, ensuring locking in rotation of the guide in the body.
- the positioner has several tabs, two of these tabs being inserted by folding into two guide grooves respectively, thus blocking the rotation of the guide in the body.
- the positioner has a single foldable tongue and the guide has several grooves position, the angular position of the guide being determined by the choice of a position grooves with the single folded tongue.
- FIG. 3a represents a perspective view of a detector of position 60 according to the invention.
- the detector comprises a guide 62 which can be rotated around of the first axis XX 'in a body 64 and a pusher 66 sliding without rotation in the guide 62 along the first axis XX '.
- the free end of the pusher leaving the guide comprises the roller 12 which can rotate around the shaft 20 of second axis YY ', perpendicular to the first axis XX'.
- Figure 3b shows a sectional view of the position sensor FIG. 3a, along a plane passing through the first axis XX 'perpendicular to the second axis YY 'of the roller 12.
- the guide 62 of circular cylindrical shape comprises a part upper 68 and a lower part 70, the upper part being of a smaller diameter than the lower part which enters a first recess 72 of the body 64 of the detector
- the first recess 72 of circular cylindrical shape, coaxial at the first axis XX ', opens on one side through one end 74 of the body 64 located on the side of the free end of the pusher and on the other side on a second recess 76 coaxial with the first, of the same shape, having a diameter slightly smaller than that of the first recess thus creating a circular bearing 78 on which a washer 80 rests.
- the second recess 76 leads to a third recess 82, leaving passage to a lower part 84 of the pusher 66, sliding at inside the body 64.
- the lower part 70 of the guide is applied by a base surface 86 perpendicular to its axis of revolution, against the washer 80, maintaining the guide in longitudinal position according to the first axis XX ', in the detector body.
- a washer-shaped positioner 88 has an edge outside 90 and an inside edge 92.
- the positioner is crimped by its edge outside 90 in the body of the detector, near its end 74, coaxially to the first axis XX '.
- the positioner 88 is crimped into the body 64 of the so as to enclose the cylindrical lower part 70 of the guide between said positioner resting on a circular surface 94 resulting from the intersection of the upper part 68 and the lower part 70 of the guide, and the washer 80.
- the guide is thus held longitudinally along the first axis XX ', irremovably in the body of the detector, between the positioner 88 and the washer 80.
- the positioner performs a second function of angular positioning in the detector body around the first axis XX '.
- the positioner 88 comprises on the one hand, on the side of its outer edge 90, notches 96 in order to make it immovable in rotation once crimped in the body 64, and on the other hand, on the side of its inner edge 92, tabs 98, regularly distributed at an angular pitch ⁇ around the first axis XX ', the faces of the tongues being parallel to the cylindrical surface of the guide.
- the sliding of the pusher 66 in the guide 62 takes place without rotation. Indeed the second axis YY 'of the roller 12 is maintained in the same direction during the sliding of the pusher, the roller 12 sliding on the side of the upper part 68 of the guide, in two guide grooves 100 symmetrical located on either side of the first axis XX '.
- the two guide grooves 100 continue towards the part lower 70 of the guide 62, up to the circular surface 94, in the form of two position grooves 102, narrower than the guide grooves, in each of which one of the tabs 98 of the positioner 88 after folding.
- FIG. 3c shows a perspective view of the guide 62 comprising the two position grooves 102.
- Figure 3b shows two folded tabs 104 almost at the horizontal, among the tongues 98, on either side of the first axis XX '.
- the folded tabs 104 respectively penetrating into one and into the other of the two position grooves 102, in order to block the guide 62 in rotation in the body 64 of the detector.
- the guide must be oriented so that the two position grooves 102 are positioned opposite the two tabs opposite chosen to be folded.
- the positioner 88 has eight tabs distributed at an angular step ⁇ equal to 45 degrees. The positioner can therefore be oriented in the body according to a 45 degree angular increment.
- the angular position ⁇ of the guide grooves 100 and by consequently that of the roller 12 sliding in these grooves, relative to the detector body, will be determined by the choice of two tabs opposite to bend in the two position grooves 102.
- figure 3d represents a top view simplified according to BB 'of the position detector 60, showing the position of the roller 12 with respect to a reference axis W 'passing through the first axis XX 'and the middle of a locking groove 106 made in the body of the detector parallel to the first axis XX '.
- the position detector is fixed relative to the direction of movement of the moving part by its mounting on a frame 108.
- the detector body has on its surface cylindrical circular, thread 110 and parallel locking groove 106 at the first axis XX '.
- a retaining washer in position 112 surrounding the detector body has a notch on the side of its inner edge internal 114, penetrating into the locking groove 106 and a recess external 116, intended to be introduced into a cavity 118 of the frame 108.
- Two nuts 120 and 122 referred to on the body on either side of the washer support 112 tighten the latter against the frame making the external offset 116, in the cavity 118 of the frame 108, preventing the rotation of the detector body in the frame.
- Two lock washers can be interposed between the tightening nuts 120 and 122 and the frame 108, in order to make the fixing of the detector more reliable.
- the implementation of the positioner is not limited to the example described and others not, may be chosen within the limits of the possibilities of realization of the positioner and the guide. For example a step of 30 degrees leads to the production of a positioner comprising twelve tabs distributed regularly.
- the positioner 88 will be made of a material allowing the folding, almost horizontally and unfolding to the initial vertical position, tabs, so that you can change a significant number of times, the angular position of the roller.
- the positioner can be made in stainless steel.
- the positioner 88 and the guide 62 are not limiting to the embodiments described.
- the positioner has several tabs and the guide one single position groove 102, one of the folded tabs entering the single position groove 102, which allows angular steps a not necessarily giving rise to two opposite tongues on the one hand and on the other side of the first axis XX '.
- a scraper seal 124 located in the lower part of the guide in an internal circular surface 126 of said guide is held in position in the guide by the washer 80.
- An O-ring seal 128 is disposed in the second recess 76. The scraper seal 124 and the seal 128 enclose the pusher 66, allowing it to slide in the guide and in the detector body by sealing the interior of the body detector in relation to the outside environment.
- the moving part has a slot whose purpose is to detect the position, for this purpose, the free end of the pusher leaving the guide, comprises a blade secured to the pusher.
- the blade must be able to be oriented and in this application, the blade should be oriented in the direction of the length of the slit of the moving part, so that it can penetrate the slot of the moving part while moving.
- the position detector according to the invention is perfectly suited to this type application.
