Abstract
The utility model relates to a rotating speed correcting mechanism of a stepless speed changing grinder, which is composed of a casing, a base, a light grating plate and a light shielding device, wherein, the rotation speed of a motor is automatically adjusted by an operating panel according to pulse signals generated from the light shielding device and a light grating hole of the light grating plate at any time through the arrangement of the light shielding device and the light grating plate which are connected with the operating panel. Thus, the rotation speed of the motor can be maintained in the state of a rotation speed arranged by a user. Thereby, a stable rotation speed is achieved. In addition, when precise grinding is implemented by the user at a low rotation speed, the rotation speed of the grinder does not descend to an almost stopping state due to the reacting force of a workpiece or because the workpiece is abutted to the grinder with an excessive great force by the user.
Description
The utility model relates to a kind of rotating speed check and correction mechanism of stepless change abrasive machine, especially so a kind of rotating speed is proofreaded mechanism, it is by the setting of Photo Interrupter and original screen panel, and be connected with control panel, the pulse signal that control panel can be at any time produced according to the grating hole of Photo Interrupter and original screen panel, automatically adjust the rotating speed of motor, make the rotating speed of motor can remain on the rotating speed state that the user sets, thereby obtain a stable rotating speed.
Known abrasive machine sets up a motor in body, connect two abrasive discs at the motor two ends, drive this two abrasive disc and carry out grinding work, yet, when the user when using abrasive machine, promptly when abrasive machine during just at grinding work-piece, workpiece can apply a reacting force to described abrasive machine, thereby increase the load of abrasive machine, make the rotating speed of this abrasive machine can do irregular variation; Or when the retroaction of workpiece was very big, regular meeting allowed the user can't very stably grasp workpiece.Said circumstances makes that abrasive machine can not be stablized, grinding work-piece equably; and make workpiece can't be ground very smoothly; even when the user can't grasp workpiece; workpiece also might fly out; can hurt user or other people; and quite high or only need grind some parts the time when the workpiece permissible accuracy of sand milling, high-revolving abrasive machine regular meeting makes the user accidentally promptly excessive, and exceeds required accuracy rating.
In addition, also have a kind of known abrasive machine that can adjust grinding wheel speed, this abrasive machine utilizes variable-resistance modulation mode to adjust the rotating speed of motor.Yet, though it can adjust the rotating speed of motor, but, when being transferred to a certain desired speed, when carrying out sawing work, this workpiece still can apply sizable load to this abrasive machine, and make the running speed of this abrasive machine still can near predetermined rotating speed, do the change of macrorelief, though the user can adjust the rotating speed that variable resistor is adjusted motor at any time, but this still can't make the rotating speed of motor remain on the constant speed state, the load that workpiece is applied on the abrasive machine is becoming at any time, the work so the user can't adjust at any time at all, and when abrasive machine during in the slow-speed of revolution, touch the reacting force of workpiece or workpiece when big, the speed of its grinding can be the state that stops to machine slowly.
The purpose of this utility model is the rotating speed check and correction mechanism that a kind of stepless change abrasive machine will be provided, especially a kind of setting by Photo Interrupter and original screen panel, and be connected with control panel, make control panel can adjust the rotating speed of motor rotor at any time automatically according to the signal that it obtained, make the rotating speed of motor rotor can remain on the rotating speed state that the user sets, thereby make this abrasive machine can very stably grind the rotating speed check and correction mechanism of work.
The purpose of this utility model is achieved in that a kind of rotating speed check and correction mechanism of stepless change abrasive machine, and it comprises:
One housing is provided with a motor in this housing, be installed with a lid in the motor both sides, and this lid can pass for motor two ends;
One base, described base place above-mentioned housing below, are provided with control panel in this base inboard, are provided with revolution speed control device and power switch in chassis outer side, and control panel, revolution speed control device are connected with power switch;
One original screen panel, this original screen panel are installed on arbitrary end of said motor, are equipped with the grating hole on original screen panel;
One Photo Interrupter, this Photo Interrupter have a depressed part that can pass through for above-mentioned original screen panel, and Photo Interrupter is installed on the cover body outside with original screen panel the same side, and are connected with above-mentioned control panel.
The rotating speed check and correction mechanism of the stepless change abrasive machine that the utility model proposes, setting by Photo Interrupter and original screen panel, and be connected with control panel, the pulse signal that control panel can be at any time produced according to the grating hole of Photo Interrupter and original screen panel, automatically adjust the rotating speed of motor, make the rotating speed of motor can remain on the rotating speed state that the user sets, thereby obtain a stable rotating speed, and when the user when precise finiss is carried out in the slow-speed of revolution, the reacting force of reason workpiece or user be not with workpiece contact abrasive machine too firmly and make the rotating speed of abrasive machine be declined to become the state that stops soon yet.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is the stereo appearance figure according to the rotating speed check and correction mechanism of a kind of stepless change abrasive machine that the utility model proposes;
Fig. 2 is the perspective exploded view according to the rotating speed check and correction mechanism of a kind of stepless change abrasive machine that the utility model proposes;
Fig. 3 is the combination synoptic diagram according to Photo Interrupter, original screen panel and the lid of the rotating speed check and correction mechanism of a kind of stepless change abrasive machine that the utility model proposes.
Below in conjunction with accompanying drawing and most preferred embodiment thereof the concrete structure that the utility model proposes is further described.
As Fig. 1, shown in Figure 2, the rotating speed check and correction mechanism of a kind of stepless change abrasive machine that the utility model proposes comprises: a housing 100, be provided with motor stator 110 at housing 100 inboard circumferential surfaces, be provided with a motor rotor 111 in motor stator 110 inboards, this motor rotor 111 can be motor stator 110 inboard rotations, described motor rotor 111 two ends all have a core 112, this diaxon core 112 rotates with motor rotor 111, at motor rotor 111 left cap unification inner cap 113, on diaxon core 112, be arranged with a bearing 114 respectively, 115, two lids 116,117 by four screws 118 and cooperate four nuts 119, with above-mentioned two lids 116,117 are fixed to described housing 100 two ends, and can pass for above-mentioned diaxon core 112, below housing 100, be provided with a base 120, in base 120, be provided with a control panel 121, be provided with a power switch 122 and a revolution speed control device 123 in a side of base 120, wherein be provided with a variable resistor (end illustrates among the figure) in the revolution speed control device 123, by by control panel 121, power switch 122 and revolution speed control device 123 threes' combination, the rotating speed check and correction mechanism of power switch 122 may command stepless change abrasive machine of the present utility model cut-offs, and can be by adjust the rotating speed of motor by the variable-resistance adjusting in the revolution speed control device 123, below control panel 121, be provided with a base plate 124, this base plate 124, control panel 121 is screwed with base 120.
