Embodiment
Below the utility model is described in further details.Referring to Fig. 1, mechanical part of the present utility model comprises that is gone up a wheel rim gripping body 1, go up wheel rim 2 and a coaxial mounted wheel rim 4 down for one, one 4 that be connected with following wheel rim, can lock or unclamp the locking head 3 of going up wheel rim, an incremental spindle encoder 8 that is connected with main shaft 9, a main shaft drives mechanism that is made up of servomotor 6 and friction pulley 7, friction pulley 7 is between the output shaft and main shaft 9 of servomotor 6.The control circuit of this device comprises main axle servo driver module 5, industrial computer 15, address card 16, programmable logic controller (PLC) 19 sum counter modules 18, main axle servo driver module 5 is connected with address card 16 with programmable logic controller (PLC) 19 respectively by industrial field bus, the output terminal of counter module 18 is connected with the respective input of programmable logic controller (PLC) 19, address card 16 is inserted in the expansion slot of industrial computer 15, and the output terminal of main axle servo driver module 5 is connected with servomotor 6.Because the above machinery and the structure and the principle of work of electric member are same as the prior art, introduce no longer in detail herein.Main improvement of the present utility model is:
(1) wheel rim zero degree mark 11 on having on the last wheel rim 2 is having following wheel rim zero degree mark 10 on the wheel rim 4 down.The zero degree mark can be groove or other figures, symbol, observes and aims at as long as be convenient to.
(2) fixing a sensor block 12 at last wheel rim upper surface, the zero degree sensor 13 of a stationkeeping is installed above this sensor block rotate path, this zero degree sensor is screwed on the pedestal of last wheel rim lifting and gripping body.Sensor block 12 can be used metal sensor block or reflector.Zero degree sensor 13 can use near switch or optoelectronic switch.TURCK Bi2-M12-AP6X type switch for example.
(3) have a digital quantity to interrupt input card 14, be inserted in the expansion slot of industrial computer 15, the output terminal of zero degree sensor 13 interrupts input card 14 corresponding input ends with digital quantity and is connected.ADVANTECH PCL730 type for example.
The course of work of the present utility model is as follows:
The first step is demarcated the zero degree alignment angles.The steps include:
1. unclamp locking head 3, wheel rim gripping body 1 in the clamping makes wheel rim 2 separate with following wheel rim 4, can rotate freely.
2. the zero degree mark 10 and 11 of wheel rim manually aligns about inciting somebody to action with messenger wire method or other measuring methods, and requiring positive error is in ± 1 °.
3. unclamp wheel rim gripping body 1, locking locking head 3 makes wheel rim 2 combine as a whole with following wheel rim 4.
4. start main axis rotation, zero degree sensor 13 interrupts input card 14 by digital quantity and triggers the industrial computer interrupt service routine in pulse of each swing circle output, reads the angle value of main axis rotation scrambler 8 outputs, and this value is zero degree alignment angles θ 0.Because sensor block 12, last wheel rim 2 and following wheel rim 4 and spindle encoder 8 are as a whole at this moment, so the angle value θ 0 that each swing circle is read is the same.It is standby to deposit this value in industrial computer 15.
In second step, measure wheel rim angular error up and down.The steps include:
5. load onto detected tyre and carry out actual measurement, at this moment, zero degree sensor 13 is still exported a pulse at each swing circle, interrupts input card 14 by digital quantity and triggers the industrial computer interrupt service routine, read the angle value of main axis rotation scrambler 8 outputs, this angle value is θ t.In like manner, the θ t of each swing circle is also identical.In industrial computer 15, ask for the difference θ of θ t and θ 0, if the absolute value of θ smaller or equal to 0.4 °, does not then need to proofread and correct; If the absolute value of θ is greater than 0.4 °, then the result with θ t-θ 0=θ deposits in the industrial computer 15.
In the 3rd step, proofread and correct wheel rim angular error up and down.The steps include:
6. finish the actual measurement of tire and unload tire later on, unclamp locking head 3, wheel rim gripping body 1 in the clamping makes wheel rim 2 separate with following wheel rim 4.
7. industrial computer 15 is according to the value of θ, sends the instruction at drive shaft rotation-θ angle by Programmable Logic Controller 19 to main axle servo driver module 5, finishes the correction of wheel rim synchronous error up and down.
8. begin the actual measurement of tire next time.
The synchronous error of wheel rim was in 0.4 ° about the utility model had been guaranteed.
Fig. 2 is the main flow chart of software that the utility model uses.The software operation flow process that above-mentioned three steps are used is same program, and software is taked different algorithms and different control methods according to different states, and sampling number N can get 1～10 positive integer according to accuracy requirement.Calculating mean value after sampling is finished is because angle has periodic characteristics, so will adopt the method calculating mean value of vector calculus.If demarcate the measuring process of zero degree, then to preserve this mean value be that zero degree alignment angles θ 0 back finishes to measure to software.If the tire measuring process, then to preserve this mean value be θ t to software, calculates the value of θ t-θ 0=θ, carries out the angular deviation compensation if the absolute value of θ is then controlled the main axle servo drive system greater than 0.4 °.
