Abstract
The utility model discloses the automatic round-the-corner device of a multi-teeth indexing table, comprising a driving system and an automatic controlling device. Carrying out remote control and automatic indexing, the utility model alters the lagging situation of manual operation and avoids the influence on measurement precision caused by human factors. The utility model can be used as an angle standard device and as a manufacture turn table for products with high requirements for diagonal indexing accuracy.
Description
The utility model is a kind of additional aut.eq. of precise angle testing tool, is made up of drive system and control system.
Multiteeth indexing table is the precision instrument of detection angles, both can be used as angle reference and has been used for measuring, and can be used as dividing apparatus again and is used for the high Precision Machining instrument of angle requirement.And the use of existing multiteeth indexing table is to use manually-operated entirely, the steps include: with the manual manipulation lifting handle fluted disc to be lifted; Take a turn for the better after the required angle with hand, operate lifting handle again and will go up fluted disc and put down, finish transposition action.With manually-operated defective be like this: one is not nimble; Two remove and apical tooth can occur when inaccurate, and fragile fluted disc causes the accident; The 3rd, limited range of application, as detecting automatic turntable precision and some detection and transposition at a distance; The 4th, people's body temperature causes environmental impact and causes precision not reach requirement.
The purpose of this utility model is to develop remote-controlled operation of a kind of energy and automatic corner, automatically the additional aut.eq. of the multiteeth indexing table of control.
The utility model is achieved with following scheme: finish fluted disc lifting and corner action with two stepper motors respectively, finish by interface controlling and driving power supply with microcomputer.
Concrete scheme is described further in conjunction with the accompanying drawings: when beginning to move, by signal of keyboard input microcomputer (A), microcomputer produces earlier a pulse power by interface (B) controlling and driving power supply (C) and rotates to the lifting shaft of lifting stepper motor (1) by shaft joint (2) drive multiteeth indexing table (3) fluted disc (work top) is risen to and make then, till the lower tooth disk drop out of gear, then driving power produces second pulse current again and gives corner stepper motor (6) rotation, be fixed on one corner gear wheel (4) engagement by corner pinion wheel (5) and last fluted disc, thereby reach the purpose of corner.What of its corner number of degrees, different and different with keyboard input microcomputer signal.Finishing the rear drive power supply at corner makes lifting stepper motor (1) return rotation by shaft coupling (2) for again a pulse current, make the rotation of multiteeth indexing table lifting shaft fall dish, upper and lower fluted disc is meshed again, thereby finished the whole procedure action of corner.If just in case produce the apical tooth phenomenon, locate also to have designed an insurance institution at shaft coupling (2), its scheme is to adopt to give shaft coupling one constant stress, its stress intensity can make elevating lever rotate just, when moment is increased, have a steel ball immediately by jack-up between shaft joint, cause microswitch work, the lifting stepper motor stops operating immediately.
Owing to carried out above scheme, the utility model has changed the manual operations of the sort of backwardness in the past, thus inaccurate fluted disc, the user mode of avoiding body temperature that environmental baseline is impacted damaged of degree of removing.And enlarged range of application widely, make the transposition operation and the detection of multiteeth indexing table all realize robotization.
Description of drawings:
Fig. 1 is a multiteeth indexing table automatic displacement device fundamental diagram, wherein: the A Control System of Microcomputer; The B interface converting system; The C driving power; 1 lifting stepper motor; 2 shaft joints and insurance institution; 3 multiteeth indexing tables; 4 corner gear wheels; 5 corner pinion wheels; 6 corner stepper motors.
Fig. 2 is a partly schematic diagram of step motor drive power amplifier.
Embodiment 1:
Microcomputer partly adopts M1C-80 personal computer central processing unit (CPU), and its chip gets final product with Z-80, and internal storage capacity can reach 48KB.All the other also have display (12 inches black and white television sets), compositions such as external storage (cassette tape recorder, the coupling of attention interface resistance) and line printer.
Interface partly adopts 1/0 interface, and its circuit mainly is made up of two 8255A interface slice, thin pieces, because this interface generality is strong, uses flexibly, and available programs changes its function, and can directly CPU be connected with peripherals.8255A
1#The interface slice, thin piece removes in order to the signal of input from insurance institution, guarantees also to can be used as the input port of data processing outside the multiple tooth calibration operate as normal, gathers the data from TA-80 photoelectric auto-collimation light pipe or other testing tool.8255A
2#The interface slice, thin piece is an output interface, in order to control the rotation of two stepper motors.
What driving power partly adopted is typical power amplifier, sees accompanying drawing 2, and wherein L is a motor windings.As long as suitably select resistance value R
0, the current value of the motor windings of flowing through is controlled within the required range.This circuit from the phase of four tunnel parallel connections as the stepper motor winding, is pressed the scale-of-two relation and selected R
0Value, thus make every road current value by the scale-of-two relationship change.Change as long as four road control end Usr make plus-minus counting with binary code, just obtain the superposition value of respective electrical stream in the output terminal stepper motor winding.Four lines can constitute 15 states that contain " 1 ", so motor windings can obtain the grading currents of 15 segmentations, thereby stepper motor is rotated by 15 segmentation step angles.
Embodiment 2:
We are simple according to BASIC, be convenient to man-machine conversation and the fast characteristics of assembly language execution speed, mix and use assembly language and BASIC to design operation program.The rotation subroutine BASIC of master routine and lifting stepper motor, the rotation subroutine assembly language of corner stepper motor.
For the check technical solution of the present invention can make multiteeth indexing table automatic displacement device reach angle measurement repeatability △ heavy≤0.06 " high-precision requirement; detect with TA-80 photoelectric auto-collimator and polyhedron according to a conventional method, the reading value of TA-80 passes through input interface (8255A
1#) gather automatically by micromotor.Results measured is △ weight=± 0.05 ".
Claims (3)
1, a kind of multiteeth indexing table automatic corner device of being made up of drive system and control system is characterized in that drive system has shaft joint (2) and corner gear wheel (4) and corner pinion wheel (5).
2, automatic corner device according to claim 1 is characterized in that corner gear wheel (4) can be fixed on the fluted disc on the multiteeth indexing table (3), and is meshed with corner pinion wheel (5).
