Abstract
The utility model discloses a bench drill with a double-microswitch protection function. The bench drill with the double-microswitch protection function comprises a bench drill body, a shield and a goggles device, wherein the shield is provided with a first microswitch, and the goggles device is provided with a second microswitch. An emergency stop switch and a power source switch are installed on the bench drill body. The first microswitch, the second microswitch, the emergency stop switch and the power source switch are connected in series. The goggles device comprises a goggles seat, a tension spring, goggles and the second microswitch. The goggles are provided with a first strong magnet. The goggles seat is provided with a second strong magnet, and the first strong magnet is matched with the second strong magnet. The second microswitch comprises a microswitch contact terminal, a press claw and a microswitch wire-passing groove. The microswitch contact terminal is installed on the goggles seat. The press claw is installed on the goggles, and is matched with the microswitch contact terminal. A machine can be shut down by turning off the power switch, turning off the emergency stop switch, opening the shield cover or opening the goggles, and therefore the danger caused by misoperation of exchanging a drill when an operator does not turn off a power source is avoided.
Description
Technical field
The utility model relates to a kind of electric tool accessory, is specifically related to a kind of double protecting device of the guard shield goggle band microswitch for bench drill.
Background technology
Existing bench drill, goggle is equipped with at the drill bit place, when bit change more, need turn off power supply and goggle is opened, install drill bit after, with goggle playback and opening power, then process again.Secondly in use there is following defective in this bench drill: it is more loaded down with trivial details at first to open and close power supply, forgets that operating personnel the maloperation meeting produces potential safety hazard in the situation of powered-down.
The utility model content
Goal of the invention: in order to overcome the deficiencies in the prior art, the utility model provides a kind of bench drill with dual crack defencive function.
For achieving the above object, the technical solution adopted in the utility model is: a kind of bench drill with dual crack defencive function, comprise table drill body, the guard shield of the first microswitch is installed and the protective glass device of the second microswitch is installed, emergency stop switch and power switch are installed on the described table drill body, and described the first microswitch, the second microswitch, emergency stop switch and power switch are in series; Described protective glass device comprises goggle seat, extension spring, goggle and the second microswitch; Described extension spring one end is connected mutually with the goggle seat, and the other end is connected mutually with goggle; Described goggle is provided with strong magnetic one, and described goggle seat is provided with strong magnetic two, and strong magnetic one and strong magnetic two are suitable; Described the second microswitch comprises microswitch contact, paw and microswitch trough, described microswitch contact is installed on the goggle seat, described goggle is provided with paw, and paw and microswitch contact are suitable, and described microswitch trough is arranged on the goggle seat.
As preferably, described power switch and emergency stop switch are the top that Rankine-Hugoniot relations up and down is installed in table drill body.
Beneficial effect: the utility model has increased microswitch and the emergency stop switch on the goggle on the basis of original almuce belt microswitch, two microswitches, emergency stop switch and power switches are connected mutually.Be in closure state at power switch and emergency stop switch, and guard shield is closed, when goggle is closed, machine works; Turn off power switch, turn off emergency stop switch, open guard shield and touch the first microswitch or open goggle and touch the second microswitch, any one that carry out in above-mentioned four operations can both make power supply disconnect machine down.The utility model makes operation easier, has simultaneously effectively avoided operator's more danger of bringing of the maloperation of bit change when not having powered-down.
Description of drawings
Fig. 1 is goggle in the utility model and the structural representation of goggle seat;
Fig. 2 is the state diagram of bench drill when closed of the goggle in the utility model;
Fig. 3 is the state diagram of the bench drill when opening of the goggle in the utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand these embodiment only is used for explanation the utility model and is not used in restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present utility model.
See also Fig. 1 to shown in Figure 3, the utility model discloses a kind of bench drill with dual crack defencive function, comprise table drill body, the guard shield of the first microswitch is installed and the protective glass device of the second microswitch is installed, emergency stop switch 1 and power switch 6 are installed on the described table drill body, and described the first microswitch, the second microswitch, emergency stop switch 1 and power switch 6 are in series; Described protective glass device comprises goggle seat 2, extension spring 3, goggle 4 and the second microswitch; Described extension spring 3 one ends are connected mutually with goggle seat 2, and the other end is connected mutually with goggle 4; Described goggle 4 is provided with strong magnetic 1, and described goggle seat 2 is provided with strong magnetic 2 21, and strong magnetic 1 and strong magnetic 2 21 are suitable; Described the second microswitch comprises microswitch contact 22, paw 42 and microswitch trough 5, described microswitch contact 22 is installed on the goggle seat 2, described goggle 4 is provided with paw 42, paw 42 and microswitch contact 22 are suitable, and described microswitch trough 5 is arranged on the goggle seat 2.
In the present embodiment, Rankine-Hugoniot relations was installed in the top of table drill body about described power switch 6 and emergency stop switch 1 were.
The utility model is in state shown in Figure 2 during bench drill start work when work, power switch 6 and emergency stop switch are in closure state, and guard shield is closed, goggle 4 closures.This moment, goggle 4 and goggle seat 2 were closed together under the effect of extension spring 3; This moment, strong magnetic 1 and strong magnetic 2 21 engaged, and it is tight to prevent effectively that machine vibration from causing goggle 4 to contact with goggle seat 2, affects the tight closure of paw 42 and microswitch contact 22; This moment, paw 42 reliably contacted with microswitch contact 22, and microswitch contact 22 makes the second microswitch closed under the pressure of paw 42, and this moment, the second microswitch was "on" position, the machine normal operation.
When operating personnel need more bit change, perhaps because maloperation when having opened goggle 4, bench drill is shut down, and machine has been changed to state shown in Figure 3 by state shown in Figure 2.This moment, goggle 4 overturn under the effect of extension spring 3, and strong magnetic 1 and strong magnetic were opened in 2 21 minutes, and paw 42 leaves the outage of microswitch contact 22, the second microswitches, machine down.
Being "on" position when the second microswitch is stressed closure, is off-position under the normal condition.
The line arrangement of the second microswitch is in the front side of table drill body, at goggle seat 2 microswitch trough 5 is set, the circuit that can prevent the second microswitch exposes and moves up and down when causing drill bit work and relevant connecting line is damaged by pressure, also can avoid the overall aesthetic that circuit exposes affects bench drill simultaneously.
In the course of work of bench drill, open guard shield, open goggle 4, close emergency stop switch or powered-down switch 6, can both make machine down, more effectively played safety protection function.
