Detailed Description
The principle of the hand and button dual-purpose manual pulse generator of the present invention is described with reference to fig. 1. The invention mainly comprises a hand signal input unit, a key signal input unit and a Central Processing Unit (CPU). The functions of the central processing unit CPU mainly comprise the functions of converting key input signals into pulse signals, converting the pulse signals into signals for controlling a machine tool, selecting circuits and other auxiliary operations.
The function of the selection circuit is specifically described as follows, when the hand signal generation unit outputs pulses and the key unit does not output the pulses, the selection circuit outputs the pulses generated by the hand unit; when the key unit has output and the hand-operated unit has no output, the selection circuit outputs the pulse generated by the key unit; when the hand-operated unit outputs, the key is pressed again, and the key is invalid; when the key generation unit outputs, the hand-operated pulse unit is shaken again, and the hand-operated unit is invalid; when the hand-cranking unit and the key unit both output or do not output, the selection circuit controls the manual pulse generator not to output pulses.
As shown in fig. 1, the signals output by the hand signal input unit and the key signal input unit are transmitted to the central processing unit; the central processing unit outputs a control signal for realizing the movement or positioning of the cutter or the workpiece on the machine tool through the differential chip.
As shown in fig. 5, the pulse generator of the present invention includes a hand-operated unit and a key unit in terms of mechanical structure, the key unit is composed of forward and reverse keys 41 and 42, and therefore, the CPU is further connected with forward and reverse indicator lights 43 and 44 (as shown in fig. 1).
In addition, when the computer is started, the control signal is fed back to the central processing unit through a circuit to realize the self-detection of the computer. Specifically, the self-test phase is entered when the manual pulse generator is powered on and started. As shown in fig. 1, sampling and feeding back the A + and B + signals output by the differential chip to the CPU, detecting the whole circuit, and if the circuit is normal, simultaneously turning on the forward indicator light and the reverse indicator light for 1 second; if the circuit is abnormal, the forward rotation indicator light and the reverse rotation indicator light are both turned off.
As shown in fig. 2, the structure of the hand cranking unit is explained in conjunction with the principles of fig. 3 and 4. In the figure, it can be seen that the inner ring tooth damping fin 11 and the outer ring tooth damping fin 12 which are made of magnetic conductive materials and the ring-shaped magnet 10 are laminated, the inner ring tooth damping fin 11 and the outer ring tooth damping fin 12 are arranged concentrically, and the inner ring tooth damping fin 11 and the outer ring tooth damping fin 12 are respectively provided with teeth 51 and 51' which have gaps between the outer ring and the inner ring, correspond to each other in tooth shape and have the same number of teeth (as shown in fig. 3). The driving crank 1 is associated with the driven rotating shaft 5 and drives a scale cover 8 to rotate, an outer ring tooth damping sheet 12 and an iron bowl 9 are fixed inside the scale cover 8, and the iron bowl 9 is mainly used for transmitting the magnetic force of the magnet 10 to the outer ring tooth damping sheet 12. Although the gap 16 exists between the iron bowl 9 and the magnet 10, the gap is small, and magnetic conduction can be realized. In addition, the inner ring tooth damper 11 and the ring magnet 10 are fixed to a fixing base 14.
The arrangement is such that the teeth of the inner and outer ring teeth damping fins 11, 12 are respectively provided with a magnetic pole N and a magnetic pole S or opposite magnetic poles. When the crank 1 is shaken, the outer ring tooth damping fin 12 rotates concentrically therewith, the outer ring tooth damping fin 12 and the inner ring tooth damping fin 11 move relatively, and the rotation can feel the click feeling according to the principle, so that the scale which is rotated is sensed. In addition, in fig. 5, a code wheel 3 which rotates concentrically with the rotary shaft 5, and a photoelectric switch 4 for detecting the rotation state are also included. Because the coded disc 3 is carved with evenly distributed slit, required pulse can be output to photoelectric switch 4 when it rotates, and the number of output pulse is in direct proportion to the angle that coded disc 3 rotated. The electrical signal generated by the photoelectric switch 4 is transmitted to the central processor unit on the circuit board 2.
In order to change the magnetic damping, the inner ring tooth damping sheet 11 and the outer ring tooth damping sheet 12 are formed by laminating a plurality of damping sheets (as shown in fig. 5); the number of the damping plates is large, the damping effect is strong, the number of the damping plates is small, and the damping effect is weak. The magnets may be disposed on both sides of the inner and outer ring teeth damping fins 11, 12, as long as the corresponding magnetic poles N and S are formed between the teeth of the inner and outer ring teeth damping fins 11, 12.
To sum up, the utility model discloses a hand and manual pulse generator of button dual-purpose can operate with two kinds of modes. Namely, signals are input to the central processing unit through the hand signal input unit, and finally the central processing unit outputs control signals; or inputting a signal to the central processing unit through the key, and finally outputting a control signal by the central processing unit.
In addition, the operation of the keys can be further functionalized. Such as: when a forward rotation key is pressed down, the pulse generator outputs a forward pulse; when the reverse key is pressed, the pulse generator outputs a reverse pulse; when the forward rotation key and the reverse rotation key are pressed simultaneously, the pulse generator does not output pulses. When the key is pressed for less than 0.5 second, only one pulse is output; the pulse signal is output at the frequency of 10Hz when the key is pressed for 0.5 to 2 seconds, the pulse signal is output at the frequency of 100Hz when the key is pressed for 2 to 5 seconds, and the pulse signal is output at the frequency of 1000Hz when the key is pressed for more than 5 seconds.
Or only one pulse can be output when the key is pressed for less than 20 seconds; the key is pressed for 20 seconds to 50 seconds, and a pulse signal is output at the frequency of 1000 Hz.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be able to cover the technical solutions and the inventive concepts of the present invention within the technical scope of the present invention.
