Embodiment
Of the background technology part, the industrial object of angular adjustment is many, and such as objects such as worktable, swing arms, but the adjusting characteristics are similar, and how difference only is structural strength and regulates on the stable deviation basic structure basically identical.Platform 1 shown in the explanation accompanying drawing 1 is that example is done more detailed elaboration to technical scheme of the present invention for the industrial object of adjustment below.
As shown in Figure 1 is a kind of angle self-checking device according to the utility model technical scheme; The industrial object that is conditioned among the figure is a platform; Be limited with two pin joints, a pin joint is a fulcrum, the pin joint of second hinge, 11 correspondences among Fig. 1; Another pin joint is a drive point, the pin joint of first hinge, 10 correspondences among Fig. 1.
Thereby; This regulating device comprises the bracing frame 6 that is articulated in said fulcrum through second hinge 11; Fixing hinged on this bracing frame and be formed with lifter 9 around hinged some rotational freedom of correspondence, and be arranged on this lifter to measure the measurement mechanism of this cage lifter lifting amount;
Wherein, the drive end of said lifter 9 is articulated in said drive point;
Accordingly, this regulating device comprises that also input connects the logic control arithmetic unit of said measurement mechanism, and the human-computer interaction device that links to each other with this logic control arithmetic unit.
So as shown in Figure 1; The central moment of inevitable second hinge 11 and first hinge 10 is fixed; And second hinge 11 is also fixed with fixing hinged centre distance, and variable has only one in the triangle of formation, just fixes centre distance hinged and first hinge 10.Fixing hingedly be connected to form among Fig. 1 through bearing pin 12.
Hinged, claim hinged-support again, according to the general classification of theoretical mechanics, comprise fixing hinged and movable hinged, in order to reduce variable, simplified structure simultaneously, employing is fixed hinged.
About lifter, be simplified structure, select the mechanism of straight line adjustment, like hydraulic cylinder, screw screw mechanism, but can not use cylinder.If adopt hydraulic cylinder, corresponding measurement mechanism is selected the grating chi for use.
Preferable selection is that the elevating mechanism of said lifter is the fixing hinged screw screw mechanism at said fulcrum of its frame, and correspondingly, the leading screw drive end is engaged in said drive point; The precision of screw screw mechanism is high, and measures and can adopt scrambler to measure, and connects a grating sensor like the axle head at leading screw 2, calculates the elongation of leading screw through the revolution of measuring leading screw.
Further selecting is to be arranged on the said frame near switch as one of said measurement mechanism, and this over against said leading screw, and should be connected in the high-speed pulse input terminal of said logic control arithmetic unit near switch output near the induction end of switch.Cost near switch will be far below grating sensor; Cost is low, and according in the regulating device of this programme in order to satisfy the secure support of platform 1, will be like the centre distance of second hinge and first hinge much larger than the helical pitch of leading screw; Like this centre distance is 1000mm; The leading screw helical pitch is 2mm, and corresponding angle changes very little, and technical error can be ignored.
Shown in Figure of description 2, the build-in attribute of leading screw thread has determined that counting can produce the signal waveform of Fig. 2 top near the counting characteristics of switch among Fig. 1, and certainly, this signal waveform is the product after the signal, and being shown among the figure is for more intuitive expression.Can produce the pulse waveform shown in 2 through digitized processing.In case what produce is pulse waveform, count in the compunication circuit, being very easy to realize so.As principle, below just set forth according to a kind of angle Automatic adjustment method of this programme.
At first; Be that single-chip microcomputer, controller or PLC have a plurality of counters, and generally also all be furnished with the high-speed pulse port corresponding to a certain counter, the increasing industry that is applied to of high-speed pulse; Related specifications is appearing at abroad of morning, in China comparison history early arranged also.Teaching material " high-speed pulse technology " as being published by publishing house of Zhejiang University October nineteen ninety has just carried out the argumentation of system to high-speed pulse.This programme application mainly is the precision that guarantees data acquisition.
And then about the angle Automatic adjustment method, the industrial object that at first is conditioned is limited with two pin joints that centre distance is c, and a pin joint is a fulcrum, and another pin joint is a drive point;
Wherein, Said point articulated makes industrial object contain rotational freedom and has angular adjustment foundation structure, and correspondingly, the fixing hinged and drive end of a lifter is articulated in said drive point; Wherein fixing centre distance hinged and said pin joint is b; Fixing hinged and centre distance drive point are variable a, form one and have and be the triangle of variable on one side, wherein variable a right angle A be the adjustment angle of industrial object; Measure the elongation of said variable a, utilize
Calculate angle A;
Thereby, through input angle A, anti-changes persuing amount a; Or through measurand a, and through controlling the size that this variable a controls angle A.
Just can try to achieve controlled quentity controlled variable through human-computer interaction devices such as man-machine interface input angle A or variable a, and then control associated mechanical device action just can obtain needed locations of structures through simple calculations.
As previously mentioned; The measuring method of said variable a is to select the mechanism of screw screw mechanism as said lifter for use; One near switch over against leading screw; Through the identification of leading screw tooth form being formed read pulse, confirm the thread number of leading screw elongation according to the umber of pulse that reads, and then obtain the elongation of leading screw according to the product of the set helical pitch of the leading screw helical pitch number corresponding with the thread number near switch.
Further; The step that also comprises correction error; This step is the pulse of being gathered if be a helical pitch to high level signal next time then for high level signal for the first time; If for the first time for low level signal is a helical pitch to low level signal next time then, thereby, degree of regulation can further be improved.
About said angle self-checking device; Further select is also to be included in each limitation travel switch that said leading screw is axially disposed within said frame upper and lower end parts; With the protection lifter, lower limit travel switch 7 and upper limit travel switch 4 shown in accompanying drawing 1.About these two travel switches, can also cash to fixing a point really in the angular setting original position, following lead limit switch is expressed as zeroising, carries out the correction of zero-bit herein.
Near switch, be chosen as cylindrically about employing,, can obtain than higher measuring accuracy in response to the physical construction of this programme near switch.
Further, be preferably 8mm as the diameter near switch of measurement mechanism, the negative effect with the helical pitch of avoiding thread produces disturbing pulse.
The driving link of said lifter 9 is a brake motor 13.The brake motor has another name called electromagnetism dead electricity braking motor, braking asynchronous motor, be totally-enclosed, fan cold, mouse-cage type certainly, the asynchronous machine of additional direct current electromagnetic brake.
The brake motor has the high-precision location requirement.Should possess as the brake motor: brake rapidly, accurate positioning, safe and reliable, the interchangeable use of brake system, characteristics such as it is simple that structure is wanted, and repair and replacement are easy.A lot of factories motor that need brake is controlled motor inertia, meets the requirements of accurate location, realizes the automatic work of machinery.
