And the bolt hole 38 that runs through along the direction that is basically perpendicular to retainer 12 axis is formed in the connector 22, and wherein, the coupling bolt (link) 40 that connects retainer 12 and assembly parts 20 passes this bolt hole 38 and inserts.
And the basal surface of bump bonding 26 comprises circular arc curved surface 42, and this circular arc curved surface 42 inwardly concaves or bending towards retainer 12 with predetermined bend radius.The radius-of-curvature of curved surface 42 is arranged to be substantially equal to the radius-of-curvature of assembly parts 20 (back will be introduced).
The pin 30 that a side of 24 is protruded from bottom side surface 12a towards cylinder unit is formed on the end of retainer 12.Pin 30 forms vertically, has predetermined diameter.Just, pin 30 protrudes along the direction identical with bump bonding 26, and because pin 30 is arranged to be basically perpendicular to the axis of retainer 12, therefore sells 30 bolts hole 38 that are basically parallel to connector 22, and separates preset distance with this bolt hole 38.
On the other hand, display window 44 is arranged on the upper surface of retainer 12, and faces toward the electroluminescent lamp 34 of sensor 14 (this sensor 14 inserts retainers 12 inside).Display window 44 is for example made by transparent resin material, and installs and be sealed in the hole 46 of retainer 12.Specifically, because the inside of retainer 12 can observe visually from the outside by display window 44, therefore can be when electroluminescent lamp 34 is luminous from the outside affirmation of retainer 12.
For example, assembly parts 20 by metal material for example brass etc. form shape shaft, and length is than the big predetermined length of axial length of retainer 12.Assembly parts 20 pass the sensing tank 48 of cylinder unit 24 and insert.
And sensing tank 48 has basic circular section shape, and by the connected component 48a between the outer surface 50a that is arranged in sensing tank 48 and cylinder barrel 50 and external communications.Connected component 48a has preset width, and the diameter of the border circular areas in this preset width ratio sensor groove 48 is narrower.And, forming dilation 50b on the cylinder barrel 50, this dilation 50b expands along the direction towards connected component 48a.These elements that comprise connected component 48a are jointly as sensing tank 48.
The radius of the border circular areas of sensing tank 48 is basic identical or bigger a little just with the radius of assembly parts 20.At this moment, the connected component 48a of sensing tank 48 is towards the outer surface opening of cylinder barrel 50, and like this, the bump bonding 26 of retainer 12 inserts among the connected component 48a.The width dimensions of connected component 48a in the sensing tank 48 is basic identical or bigger a little just with the width dimensions of bump bonding 26.
Pin-and-hole 28 forms basic parallel with first and second screw holes 52,54, and along the equidirectional opening, and screw hole 52,54 and pin-and-hole 28 are spaced from each other preset distance (seeing Fig. 4 and 6).And, equal bolt hole 38 substantially and sell between 30 distance along the distance of the axial direction of assembly parts 20 between first screw hole 52 and the pin-and-hole 28 along retainer 12 axial directions.
When retainer 12 was assemblied on the assembly parts 20, first screw hole 52 was arranged in the position facing to bolt hole 38, and the coupling bolt 40 that passes bolt hole 38 is threadedly engaged with this first screw hole 52.Therefore, comprise that the position-detection sensor 10 of retainer 12 is connected with assembly parts 20.At this moment, the pin 30 of retainer 12 inserts pin-and-hole 28, and therefore, assembly parts 20 are located and be assembled to retainer 12 by coupling bolt 30 and pin 30.
More particularly, assembly parts 20 are mounted to like this, and promptly its other end (this end has second screw hole 54 that is formed at wherein) protrudes the fixed range (see figure 2) from the end of retainer 12.
And aforementioned assembly parts 20 are introduced by the situation that assembly parts 20 form the non-tubular shaft of round section hereinbefore, and but, the present invention is not limited to this feature.For example, assembly parts 20 can also be quadrangular section, and it has similar quadrangular section shape corresponding to sensing tank 48.And assembly parts 20 can form the hollow cylindrical shape.Specifically, when the position-detection sensor 10 that comprises retainer 12 connects and is assembled on the cylinder unit 24,, the shape of assembly parts 20 is not particularly limited as long as assembly parts 20 have sufficient intensity.
The basic structure of the position-detection sensor 10 of the embodiment of the invention as mentioned above.To introduce position-detection sensor 10 below and be assembled to situation on the cylinder unit 24 by assembly parts 20.
At first, assembly parts 20 are connected with the retainer 12 that constitutes position-detection sensor 10.At this moment, as shown in Figure 4, assembly parts 20 are arranged on the bottom side surface of retainer 12, and the pin 30 of retainer 12 inserts (see figure 8) in the pin-and-hole 28.And the coupling bolt 40 that passes bolt hole 38 insertions is screwed in first screw hole 52 of assembly parts 20.At this moment, retainer 12 and assembly parts 20 are arranged in parallel, and sell 30 and insert in the pin-and-hole 28, therefore, make retainer 12 with respect to assembly parts 20 location.And by assembly parts 20 are rotated so that first screw hole 52 and the bolt hole 38 of retainer 12 are mated around the center of pin 30, first screw hole 52 can be arranged to facing to bolt hole 38.Like this, insert in the pin-and-hole 28 by at first selling 30, the bolt hole 38 and first screw hole 52 can be arranged to overlap on same line at an easy rate.
In addition, by making that pass the coupling bolt 40 and first screw hole 52 that bolt hole 38 inserts is threadedly engaged with, the position-detection sensor 10 that comprises retainer 12 by coupling bolt 40 with assembly parts 20 (see figure 2) that links into an integrated entity.Because an end of retainer 12 remains on the assembly parts 20 by pin 30, and the other end remains on the assembly parts 20 by coupling bolt 40, so retainer 12 can be connected with assembly parts 20 and be integral more firmly.
And, between bump bonding 26 that guarantees retainer 12 and assembly parts 20, have under the state in preset distance gap, retainer 12 and assembly parts 20 are linked together.
Then, the position-detection sensor 10 that is connected with assembly parts 20 is assembled on the cylinder unit 24.At this moment, assembly parts 20 are inserted into the openend of the sensing tank 48 of cylinder unit 24.Assembly parts 20 pass sensing tank 48 and insert, and like this, position-detection sensor 10 is arranged in the outside of the outer surface 50a of cylinder barrel 50 by the connected component 48a of sensing tank 48.
In addition, position-detection sensor 10 moves along sensing tank 48 with assembly parts 20, and move to can detect the correct position of piston 31 positions by position-detection sensor 10 after, position-detection sensor 10 is fixed on this correct position.
When the detecting sensor 10 of such fixed position, run through the coupling bolt 40 of retainer 12 by rotation, the connector 22 of retainer 12 and assembly parts 20 are along approaching each other direction tension.And the bottom side surface 12a of retainer 12 is crushed under the state of the outer surface 50a of cylinder barrel 50, and the outer surface of assembly parts 20 against with the inner wall surface that is pressed in sensing tank 48 on (see figure 7).Therefore, the connected component 48a of sensing tank 48 is stuck, and the dilation 50b of cylinder barrel 50 is in the state by retainer 12 and assembly parts 20 clampings.
In other words, the bottom side surface 12a of retainer 12 is compressed against on the outer surface 50a of cylinder barrel 50 by the holding force of coupling bolt 40 with setting pressure P1.On the other hand, the outer surface of assembly parts 20 is compressed against (see figure 7) on the inner wall surface of sensing tank 48 with setting pressure P2.
Therefore, position-detection sensor 10 is by retainer 12 and assembly parts 20 and be fixed on correct position with respect to sensing tank 48.At this moment, as shown in Figure 8, the bump bonding 26 of retainer 12 and the outer surface of assembly parts 20 are arranged to separately preset distance.
At last, the gib screw 56 that screw thread is screwed in second screw hole 54 of assembly parts 20 rotates, and gib screw 56 moves when the bottom 48b towards sensing tank 48 protrudes, and therefore, assembly parts 20 quilts are upwards pushed towards the sidepiece of the connected component 48a of sensing tank 48.Therefore, the outer surface of assembly parts 20 is pressed against on the inner wall surface of sensing tank 48, and with the contact action of this inner wall surface under fixing (see figure 9).More particularly, position-detection sensor 10 is stuck between retainer 12 and the assembly parts 20 by the dilation 50b that makes cylinder barrel 50 and fixing with respect to cylinder unit 24, in addition, because assembly parts 20 are fixed with respect to sensing tank 48 by gib screw 56, therefore with fixed position, solid and reliable ground detecting sensor 10.
In aforementioned manner, in embodiments of the present invention, when position-detection sensor 10 was assembled on the cylinder unit 24, after assembly parts 20 were installed on the bottom side surface 12a of position-detection sensor 10 in advance, assembly parts 20 passed the sensing tank 48 of cylinder unit 24 and insert.And, twist under the effect at the screw thread of coupling bolt 40, constitute that the retainer 12 of position-detection sensor 10 and assembly parts 20 move so that approaching each other, and fix by the dilation 50b that between them, blocks the cylinder barrel 50 in the cylinder unit 24.
Like this, position because be resisted against by the bottom side surface (sensor 14 is packed in this retainer) that makes retainer 12 on the outer surface 50a of cylinder barrel 50, therefore when position-detection sensor 10 fixedly the time, the mutual alignment of retainer 12 and cylinder barrel 50 concerns and can not change.Specifically, at the magnetic sensor 32 of retainer 12 inside be arranged between the piston 31 of cylinder barrel 50 inside and be maintained fixed distance, therefore, can obtain stable testing result by magnetic sensor 32.In other words, with be used for the general position detecting sensor (in this general position detecting sensor, the relative position of position-detection sensor and piston is fixed in mounting groove at position-detection sensor and is easy to change when inner) in the assembly parts texture ratio, position-detection sensor 10 of the present invention can improve accuracy of detection.
And, because assembly parts 20 can be screwed into gib screw 56 in second screw hole 54 and fixing with respect to sensing tank 48 by screw thread, therefore coupling bolt 40 can screw thread rotation, and under assembly parts 20 keep being installed on state in the sensing tank 48, comprise that the position-detection sensor 10 of retainer 12 self can be pulled down from assembly parts 20.
Therefore, comprise that the attended operation of changing position-detection sensor 10 can be easy to carry out, this makes it possible to ressemble the another location detecting sensor with different size to assembly parts 20 and use identical assembly parts 20.
For example, when different position-detection sensors is installed on the cylinder unit 24,, therefore, can easily He apace it be installed on the position that can detect piston 31 because position-detection sensor is assemblied on the assembly parts 20 of predetermined fixed.That is, do not need to carry out difficulty and operation complicated, that on cylinder unit 24, readjust the position of position-detection sensor 10, and can improve the repeatability of the installation site of position-detection sensor 10 on cylinder unit 24.
And, because assembly parts 20 are made by metal material, therefore when position-detection sensor 10 is fixed in the sensing tank 48, even when assembly parts 20 are pressed against on the inner wall surface of sensing tank 48, assembly parts 20 can not be out of shape yet, and the permanance of assembly parts 20 can not reduce.And, compare with the situation that assembly parts 20 are made by resin material, because the intensity of assembly parts 20 improves, therefore, coupling bolt 40 can be arranged to bigger value with the fastening force (Tightening moment) that assembly parts 20 are threadedly engaged with.Therefore, position-detection sensor 10 can firmly and stably be fixed on the cylinder unit 24 by coupling bolt 40.
In the position-detection sensor 10 of previous embodiment, the rear surface of having introduced bump bonding 26 forms with bowed shape and curves inwardly, and but, the present invention is not limited to this feature.The rear surface of bump bonding 26 can also form plane surface.
And shown in Fig. 2 and 3, opening 18 sidepieces that assembly parts 20 constitute at retainer 12 protrude given length from retainer 12.But, assembly parts 20 also can be for example protrude with opposite way from the sidepiece of the connector 22 of retainer 12.And, assembly parts 20 are protruded from the two ends of retainer 12 respectively.
