Abstract
The utility model relates to a kind of machine tool chip removal device motor overload protection device, belongs to motor overload protection field; Comprise motor, motor shaft connection rotating shaft, roller end side is provided with home block, rotating shaft external stability inductor, and inductor is by line connecting controller, and controller is by connection motor.The utility model is damage equipment not, safe and reliable.
Description
Technical field
The utility model relates to a kind of machine tool chip removal device motor overload protection device, belongs to motor overload protection field.
Background technology
Existing electric motor protecting mainly adopts torque guard, mainly contains two shortcomings, and when being first each appearance overload, motor does not all stop operating, the skidding until torque guard overload breaks down, and such torque guard all needs to change at every turn; Next be if torque guard defective or bear moment of torsion excessive time, protective effect cannot be formed to motor, cause motor overload to break down.
Utility model content
The purpose of this utility model is to provide a kind of machine tool chip removal device motor overload protection device, and not damage equipment is safe and reliable.
Machine tool chip removal device motor overload protection device described in the utility model, comprise motor, motor shaft connection rotating shaft, roller end side is provided with home block, rotating shaft external stability inductor, and inductor is by line connecting controller, and controller is by connection motor.
During electric motor starting; motor shaft drives axis of rotation; home block is with axis of rotation, and home block is not positioned at rotating shaft core position, and the distance of home block and inductor is cyclically-varying; when exceeding setting-up time; when inductor does not sense home block, inductor sends signal to controller, controller power alarm; protection motor, avoids motor impaired.
Described inductor is proximity switch; Home block is when proximity switch, and proximity switch can sense home block, exceedes setting-up time, and when proximity switch fails to sense home block, illustrate that axis of rotation is abnormal, proximity switch sends signal to controller, controller power alarm.
Compared with prior art, the beneficial effects of the utility model are:
(1) the utility model structure is simple, by arranging home block and inductor, can judge that spindle operation is abnormal in time, and by controller power alarm, motor damage avoided by protection motor, safe and reliable;
(2) overload protection is reliable in time, avoids rotating shaft and damages, simplify maintenance work, saved cost;
(3) simple installation, applied widely.
Accompanying drawing explanation
Fig. 1 is the structural representation of an embodiment of the present utility model.
In figure: 1, proximity switch 2, home block 3, rotating shaft.
Detailed description of the invention
Below in conjunction with embodiment, the utility model is described further:
As shown in Figure 1, machine tool chip removal device motor overload protection device described in the utility model, comprises motor, motor shaft connection rotating shaft 3, and side, rotating shaft 3 end is provided with home block 2, rotating shaft 3 external stability inductor, and inductor is proximity switch 1; Proximity switch 1 is by line connecting controller, and controller is by connection motor.
Operation principle:
During electric motor starting, motor shaft drives rotating shaft 3 to rotate, and home block 2 rotates with rotating shaft 3; home block 2 is not positioned at rotating shaft 3 shaft core position, and home block 2 is cyclically-varying with the distance of proximity switch 1, when home block 2 enters proximity switch 1 induction range; proximity switch 1 can sense home block 2; when exceeding setting-up time, proximity switch 1 does not sense home block 2, illustrates that exception is rotated in rotating shaft 3; proximity switch 1 sends signal to controller; controller power alarm, protection motor, avoids motor impaired.
Claims (2)
1. a machine tool chip removal device motor overload protection device; it is characterized in that; comprise motor; motor shaft connection rotating shaft (3); rotating shaft (3) side, end is provided with home block (2); rotating shaft (3) external stability inductor, inductor is by line connecting controller, and controller is by connection motor.
2. machine tool chip removal device motor overload protection device according to claim 1, is characterized in that, inductor is proximity switch (1).
