Abstract

The utility model discloses a protection mechanism of a drilling machine motor, and relates to the technical field of drilling machine processing. The protection mechanism of the drilling machine motor comprises a photoelectric encoder used for detecting the rotation state of a drilling machine main spindle. The protection mechanism further comprises a controller, and the controller is connected with the photoelectric encoder and the drilling machine motor to achieve the control purposes of receiving signals of the photoelectric encoder and stopping working of the drilling machine motor. The photoelectric encoder detects the working state of the drilling machine main spindle in processing of a drilling machine in real time, when the drilling machine main spindle stops rotating due to the fact that a drill bit is clamped, working of the drilling machine motor can be stopped at the first time, and safety of the drilling machine motor is effectively guaranteed.

Description

A kind of drill motor protection mechanism
Technical field
The utility model relates to drilling machine processing technique field, is particularly useful for a kind of drill motor protection mechanism.
Background technology
Bench drill is called for short bench drill, is the requisite equipment of machine-building and various repair factory, and volume is small and exquisite, easy and simple to handle, is conventionally arranged on the small-sized hole processor bed using in dedicated.Bench drill bore diameter, generally below 13 millimeters, is generally no more than 25 millimeters.Its main shaft speed change is generally realized by changing the position of V-belt on tower belt wheel, and axis feeding is by manual operation.
In prior art, in drilling machine process, when having the place boring of hook groove or counterbore at some, if the cutting amount of feeding is too much or feed speed is too fast, will there is the stuck accident on workpiece of drill bit, motor electric current now, the more than 6 times of rated current, if disable motor power supply not in time, even short several seconds, will motor damage or other accident.
Utility model content
(1) technical problem that will solve
Problem to be solved in the utility model is, a kind of drill motor protection mechanism is provided, and prevents that drill motor from damaging.
(2) technical scheme
For addressing the above problem, the utility model provides a kind of drill motor protection mechanism, and it comprises drill motor and drill press spindle, and described protection mechanism also comprises:
Detecting element, for detecting in real time the rotary state of drill press spindle.
Controller, the signal spreading out of for receiving detecting element, and export control signal.
Wherein, described controller is connected with drill motor, and described detecting element is connected with controller.
Wherein, described detecting element is located at the upper end of described drill press spindle, and is predeterminable range with the external diameter of drill press spindle.
Wherein, described detecting element is photoelectric encoder.
(3) beneficial effect
The utility model detects the duty of drill press spindle in drilling machine processing in real time by photoelectric encoder, when drill bit is stuck while causing drill press spindle to stop operating, can stop the work of drill motor the very first time, has effectively ensured the safety of machine motor.
Accompanying drawing explanation
Fig. 1 is the structured flowchart of a kind of embodiment of the utility model;
Fig. 2 is the structural representation of a kind of embodiment of the utility model.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.
As shown in Fig. 1~2, described drilling machine protection mechanism comprises drill motor 4 and drill press spindle 2, also comprises:
Detecting element 1, for detecting in real time the rotary state of drill press spindle 2.
Controller 3, the signal spreading out of for receiving detecting element, and export its control signal.
Wherein, described controller 3 is connected with drill motor 4, and described detecting element 1 is connected with controller 3.
Preferably, described photoelectric encoder 1 is arranged at the upper end of drill press spindle 2, and is predeterminable range with the external diameter of drill press spindle 2.
Preferably, described detecting element 1 is photoelectric encoder.
Wherein, described photoelectric encoder 1 is in order to detect the rotary state of drill press spindle 2, and after starting drilling machine, drill press spindle just 2 can rotate, if there is drill bit stuck phenomenon, main shaft also just stops operating, and now, photoelectric encoder 1 just can be passed to controller 3 signal, by controller 3, passing to drill motor 4 again quits work it, like this, in the very first time, close the power supply of motor, guaranteed the safety of drill motor 4.
Above embodiment is only for illustrating the utility model; and be not limitation of the utility model; the those of ordinary skill in relevant technologies field; in the situation that not departing from spirit and scope of the present utility model; can also make a variety of changes and modification; therefore all technical schemes that are equal to also belong to category of the present utility model, and scope of patent protection of the present utility model should be defined by the claims.
