Detailed description of the invention
The present invention will be further described with detailed description of the invention below in conjunction with the accompanying drawings.
As shown in Figure 1, a kind of high-precision optical level gauge of convenient regulation, the level gauge body 2 including pedestal 2, being rotatably connected on pedestal upper surface by the vertical axes being perpendicular to pedestal upper surface and the connecting bottom board 3 being arranged on pedestal bottom, this internal telescope being provided for measuring of level gauge, also need on level gauge body to arrange a micro-spiral 5 that inclines for accurate adjustment, one pipe spirit level 4 parallel with telescopical collimation axis is set at level gauge body one side, to monitor depth of parallelism during accurate adjustment program simultaneously.In order to complete just to debug efficiently and easily, as shown in Figure 2 and Figure 3, we can arrange a spherical hollow space 31 in the center of connecting bottom board, and the upper and lower surface of the through connecting bottom board in both sides up and down of this spherical hollow space, so that spherical hollow space is cydariform small in the end and big in the middle.One discoid rocker piece 32 is set in spherical hollow space, the sphere that the lateral surface of rocker piece is and spherical hollow space is adaptive so that rocker piece can in spherical hollow space 360 degree of all-direction rotations.Centrally disposed the one of rocker piece is perpendicular to the connection circular hole 321 of upper and lower surface, one swing arm 33 is vertically threaded on the lower surface of pedestal from bottom to up after the connection circular hole of rocker piece, swing arm arranges the stop nut 35 of the rocker piece that reclines being positioned at rocker piece upper position, swing arm arranges the spacing ring 331 of the rocker piece that reclines being positioned at rocker piece lower position, so that rocker piece is at the axial upper limit of swing arm.It is to say, the weight of level gauge body now and pedestal all passes to rocker piece by swing arm, and it is in a kind of quick condition.It addition, arrange a spherical correction weight 34 in the lower end of swing arm, and the edge of connecting bottom board upper surface arranges at least three regulation screw 36, it is preferable that the quantity of regulation screw is four.When we unscrew regulation screw, the upper end of regulation screw can be resisted against on the lower surface of pedestal.Lower surface at connecting bottom board arranges three telescoping support feet 9 around spherical hollow space, so that swing arm is positioned at the centre of telescoping support foot.
During measurement, after we have set up telescoping support foot, we need first to be screwed in connecting bottom board regulation screw, to make it be separated with pedestal, so, pedestal and level gauge body i.e. can be at quick condition, and now swing arm can swing back and forth under the action of gravity of correction weight, finally it is automatically adjusted to plumb line position, so that level gauge ontology alignment is to level.So we only need the regulation screw of turn the most successively, make the upper end lower surface against pedestal of regulation screw, the position of level gauge body can be made to fix, thus complete the first of levelness and debug.Then accurate adjustment program can be carried out by micro-spiral that inclines, till the bubble of pipe spirit level is placed in the middle.It should be noted that, in order to ensure initial adjustment precision, we should make swing arm pass pedestal and level gauge body as an overall center of gravity, and the lower surface that telescopical collimation axis is arranged to pedestal is paralleled, so can ensure that in a free state, swing arm can be automatically adjusted to plumb line position, will not produce slight inclination because of the bias of level gauge body gravity.It addition, we also can arrange latticed lubrication groove outside rocker piece on sphere, in lubrication groove, it is coated with lubricant grease, to reduce frictional force when rocker piece rotates in spherical hollow space, it is ensured that swing arm can be adjusted to plumb line position completely simultaneously.And regulate screw and expose the upper end of connecting bottom board and can be set to bulb, and hexagonal rotation section is set at the spiro rod section of regulation screw, in order to it is rotated by instruments such as spanners.
Installation for the ease of rocker piece, we need to arrange two at the upper surface of connecting bottom board equally spacedly around the axis that spherical hollow space is vertical and insert groove 311, that is, two center lines inserting groove are positioned at the diametric(al) of spherical hollow space, the medial surface inserting groove is connected with spherical hollow space and forms opening shape, the lateral surface inserting groove is the face of cylinder that diameter is equal with the spherical diameter of spherical hollow space, this lateral surface extends internally until tangent with the sphere of spherical hollow space along the vertical axis of spherical hollow space, and the width inserting groove should be greater than the thickness of rocker piece.So, when we need to install, can first make discoid rocker piece perpendicular with base-plates surface, now rocker piece can be put into two and insert in groove；When rocker piece to insert in groove move to bottom time, sphere outside rocker piece fits with the sphere of spherical hollow space, and the centre of sphere of two spheres overlaps, and rocker piece is rotated 90 degree by again, making it parallel with pedestal, rocker piece now can be spacing in spherical hollow space；Then we again by swing arm from bottom to up through the connection circular hole on rocker piece, and make the spacing ring of swing arm recline rocker piece, then screw on stop nut in the upper end at swing arm, can make swing arm axial limiting on rocker piece；Finally again swing arm is threaded on the lower surface of pedestal.
It should be noted that, we can be connected one end first threaded back nut on swing arm with pedestal, this back nut is the most integrally connected and composed by hexagonal locking end and discoidal supported end, so, after swing arm is connected with base thread, we can lock back nut by hexagonal locking end, make the circular end face of its supported end tightly against the lower surface of pedestal, so, on the one hand the self-locking of swing arm can be realized, it is avoided to loosen voluntarily, be conducive to the perpendicularity improving swing arm with pedestal lower surface simultaneously, avoid reducing the precision just debugged because of the deflection of swing arm.
In order to monitor the depth of parallelism just debugged, we also can arrange the transparent spherical shell 7 that a glass is made in the bottom of swing arm, the medial surface bottom of spherical shell arranges the centering graduation mark 72 of decussation, and the cross point of centering graduation mark should be positioned on the extended line of swing arm axis, in spherical shell, place the spherical ball 71 that a rustless steel is made simultaneously.When swing arm is in plumb line position, on the medial wall of spherical shell, the cross-point locations of centering graduation mark should be at minimum point, and therefore, ball should be located just on the cross point of centering graduation mark of decussation.When swing arm has slight deflection, ball i.e. deviates the cross point of centering graduation mark.
In order to improve the precision of accurate adjustment program, we also can be respectively provided with the axially extended distance rod 6 along telescopical collimation axis in the forward and backward side of pedestal, and the distance rod of the forward and backward side of pedestal is coaxially arranged.In addition, we need to arrange an adjustable stem 8 straight up in the upside of distance rod front end, adjustable stem is flat rod, adjustable stem arranges vertical groove in the middle of the sidewall of level gauge body, transparent senior executive 81 such as grade it is embedded in groove, waiting on two distance rods is connected by plastic flexible pipe bottom senior executive, fills red liquid in waiting senior executive, waits and arranges the correction scale that can show liquid level on the pipe shaft of senior executive.
The distance rod of the present invention can be threaded connection with on pedestal, in order to dismounting.Specifically, as it is shown in figure 5, we can be respectively provided with a circular sleeve 11 in the forward and backward side of pedestal, the axis of sleeve is paralleled with collimation axis, and the lateral surface of sleeve arranges the external screw thread of dextrorotation.Correspondingly, being connected one end at distance rod with pedestal and arrange a connecting stud 61, the external diameter of connecting stud is consistent with the external diameter of sleeve, and the external screw thread being arranged on connecting stud lateral surface is left hand thread.Additionally, we also need to arrange the connection-peg 65 adaptive with sleeve medial wall in the end of connecting stud, the sidewall of connection-peg arranges axial draw-in groove 651, the medial wall of sleeve end arranges a shop bolt 111.Can be connected by a lock sleeve 62 between connecting stud with sleeve, the centre position, medial wall of lock sleeve is wholely set inwardly protruded stripper loop 621, thus lock sleeve is separated into two parts, the inwall being positioned at stripper loop both sides in lock sleeve is respectively provided with the female thread of left-handed female thread and dextrorotation.
When we need to be connected on pedestal distance rod, can be first by the connection-peg alignment sleeve retainer on distance rod, lock sleeve is placed between connection-peg and sleeve simultaneously, lock sleeve one end engages with sleeve, the other end engages with connecting stud, now the connection-peg of connecting stud end is then positioned at lock sleeve, the end of connection-peg then alignment sleeve retainer endoporus, the shop bolt of the draw-in groove of connection-peg sidewall then alignment sleeve retainer medial wall.Then rotation lock set, externally threaded oppositely oriented due to connecting stud and sleeve, therefore, close to each other in connecting stud is threaded into lock sleeve with sleeve simultaneously, the shop bolt of draw-in groove then enters in the draw-in groove of connection-peg, thus connection-peg can be stoped to rotate.Along with the rotation of lock sleeve, connection-peg enters axially in sleeve, until the end face of connection-peg is resisted against the bottom surface of sleeve tightly, thus is reliably threaded on pedestal by distance rod.When needs dismounting distance rod, oppositely rotation lock is only needed to overlap.Rely on shop bolt and the effect of draw-in groove, distance rod can be made to be accurately positioned, and then make the adjustable stem keeping parallelism of pedestal both sides, to guarantee the depth of parallelism Adjustment precision of collimation axis.
The present invention in use, debug by the first of collimation axis levelness that can complete level gauge body the most in the manner aforesaid.Then we can be at the front and rear sides of pedestal threaded distance rod respectively, then, telescope is sighted the senior executive such as grade on the adjustable stem of front side, and reading corrects scale value accordingly, this correction scale value is compared with the correction scale value shown by liquid level in such senior executive, i.e. can get the first difference of collimation axis and the contour intraluminal fluid face height of front side；Then level gauge body is rotated 180 degree, telescope is made to sight the senior executive such as grade on the adjustable stem on rear side of pedestal, and reading corrects scale value accordingly, this correction scale value is compared with the correction scale value shown by the contour intraluminal fluid face of rear side, i.e. can get the second difference of collimation axis and the contour intraluminal fluid face height of rear side.Owing to front and back waiting liquid in senior executive to be connection, therefore its liquid level is completely the same, when collimation axis is in level, above-mentioned first difference and the second difference should be completely the same, otherwise, if it is inconsistent, the most fine-tuning micro-spiral that inclines, observes and records the first difference and the second difference the most again, until first, second difference is identical, accurate adjustment program can be completed, make collimation axis keep level.Certainly, distance rod front and back preferably can be set to the length of one meter, in order to the calculating of collimation axis parallelism error and adjustment.
For the ease of the liquid level in the senior executives such as observation, as shown in Figure 6, we can arrange the floating cylinder 82 of cylinder on the liquid level waiting senior executive, the reference graduation of one cincture is set on the periphery of floating cylinder, reference graduation can be set to redness, thus can the most accurately correction scale on the senior executive such as comparison, in order to accurately read liquid level.
It should be noted that the upper end of senior executive such as grade should be opened, consequently facilitating the lifting of liquid in pipe is floated, we are when needs are measured, can be by liquid by the senior executives such as the opening injection of senior executive upper end such as grade.Additionally, after completing the accurate adjustment program of levelness, we should remove the distance rod of both sides before and after pedestal in time, in order to level gauge starts the measurement needing to measure point.
For the ease of observation with calculate the first difference and the second difference, we can arrange corresponding adjustable stem height regulating mechanism, by adjusting the height of adjustable stem, makes the correction scale value shown by liquid level in senior executive that waits on the adjustable stem of pedestal both sides keep identical.Specifically, as shown in Figure 1, we can arrange an adjustable stem support 63 in the outer end of distance rod, the top of adjustable stem support arranges a vertical guide cylinder 631, the bottom of adjustable stem support then arranges the regulation cylinder 64 coaxial with guide cylinder, and the upper end of adjustable stem arranges guide post 83, and guide post fits in guide cylinder, the lower end of adjustable stem is then connected with the piston rod regulating cylinder, thus can be lifted by regulation air cylinder driven adjustable stem.In addition, as shown in Figure 7, the air bag 66 that the cylinder body of regulation cylinder bottom is made with a rubber by air inlet pipe 67 is connected, one socket back-moving spring (not shown) on the piston rod is set in the cylinder body on regulation cylinder top, arranging in air inlet pipe can be from air bag to the first check valve 68 of circulation in cylinder body, outside air can be made to enter the second check valve 69 in air inlet pipe also by connecing one by pipeline in air inlet pipe between air bag and the first check valve, then a manual air bleeding valve 70 is connect by by pipeline in air inlet pipe between cylinder body and first check valve of regulation cylinder.So, when we need the adjustable stem of lifting side, the air bag that the squeezable regulation cylinders with this adjustable stem lower end connects, air pressure in air bag rises, thus enter in regulation cylinder by the first check valve, second check valve then can stop air to leak, and the piston rod of regulation cylinder can promote adjustable stem to rise to adjust the height of adjustable stem；When unclamping air bag, forming negative pressure in air bag, now extraneous air can be entered in air bag by the second check valve and air inlet pipe；When we need to make adjustable stem decline, can open air bleeding valve, make the air of regulation cylinder block bottom leak, now back-moving spring drives piston rod to move down together with adjustable stem.By adjusting the height of adjustable stem, can make pedestal both sides adjustable stem wait the correction scale shown by liquid level in senior executive identical, to be conducive to simplifying the water transfer Pingdu program of collimation axis.
