Any operation of turning off the power switch, turning off the emergency stop switch, opening the shield or opening the gobe can cause the bench drill to stop, thereby avoiding danger caused by replacing a drill bit by an operator without power off.
Description
Technical field
The present invention relates to a kind of electric tool accessory, be specifically related to a kind of double protecting device that is used for the guard shield goggle band microswitch of 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, process then again.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, secondly forgets that operating personnel the maloperation meeting produces potential safety hazard under the situation of powered-down.
Summary of the invention
Goal of the invention: in order to overcome the deficiency that exists in the prior art, the present invention provides a kind of bench drill with dual crack safety device.
For realizing above-mentioned purpose; The technical scheme that the present invention adopts is: a kind of bench drill with dual crack safety device; Comprise bench drill body, collar bush, the guard shield of first microswitch is installed and the goggle device of second microswitch is installed; On the said bench drill body emergency stop switch and power switch are installed, said first microswitch, second microswitch, emergency stop switch and power switch are in series; Said goggle device comprises goggle seat, goggle and second microswitch; Said second microswitch is installed on the goggle seat, and the goggle seat is installed on the collar bush; Said goggle seat is provided with hole one, and goggle is provided with hole two, and hole one is suitable with hole two, and bolt connects goggle and goggle seat through hole one, hole two; Said second microswitch comprises cover plate, contact-making surface, contact, paw, arc groove and trough; Said cover plate is connected with the goggle seat mutually, and cover plate is provided with boss, and boss and contact-making surface are suitable; Said goggle is provided with paw, and said contact is installed on the goggle seat, and the goggle seat is provided with arc groove, and arc groove and paw are suitable, and paw and contact are suitable; Also be provided with locating hole and trough on the said goggle seat, goggle is provided with navigation button, and navigation button and locating hole are suitable.
As preferably, said cover plate is riveted on the goggle seat.
As preferably, said power switch and emergency stop switch are the side that Rankine-Hugoniot relations up and down is installed in the bench drill body.
Beneficial effect: the present invention has increased microswitch and the emergency stop switch device on the goggle on the bench drill of original almuce belt microswitch.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 first microswitch or open goggle and touch second microswitch, any one that carry out in above-mentioned four operations can both make power supply break off machine down.The present invention makes operation easier, has effectively prevented operator's more danger that maloperation brought of bit change when not having powered-down simultaneously.

The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment; Further illustrate the present invention; Should understand these embodiment only be used to the present invention is described and be not used in the restriction scope of the present invention; After having read the present invention, those skilled in the art all fall within the application's accompanying claims institute restricted portion to the modification of the various equivalent form of values of the present invention.
See also Fig. 1 to shown in Figure 4; The present invention discloses a kind of bench drill with dual crack safety device; Comprise bench drill body, collar bush, the guard shield of first microswitch is installed and the goggle device of second microswitch is installed; Emergency stop switch 1 and power switch 2 are installed on the said bench drill body, and said first microswitch, second microswitch, emergency stop switch 1 and power switch 2 are in series; Said goggle device comprises goggle seat 3, goggle 4 and second microswitch; Said second microswitch is installed on the goggle seat 3, and goggle seat 3 is installed on the collar bush; Said goggle seat 3 is provided with hole 1, and goggle 4 is provided with hole 2 41, and hole 1 is suitable with hole 2 41, and bolt connects goggle 4 and goggle seat 3 through hole 1, hole 2 41; Said second microswitch comprises cover plate 5, contact-making surface 6, contact 7, paw 8, arc groove 9 and trough 10; Said cover plate 5 is connected with goggle seat 3 mutually, and cover plate 5 is provided with boss 51, and boss 51 is suitable with contact-making surface 6; Said goggle 4 is provided with paw 8, and said contact 7 is installed on the goggle seat 3, and goggle seat 3 is provided with arc groove 9, and arc groove 9 is suitable with paw 8, and paw 8 is suitable with contact 7; Also be provided with locating hole 32 and trough 10 on the said goggle seat 3, goggle 4 is provided with navigation button 42, and navigation button 42 is suitable with locating hole 32.
In the present embodiment, said cover plate 5 is riveted on the goggle seat 3, and Rankine-Hugoniot relations was installed in the side of bench drill body about said power switch 2 was with emergency stop switch 1.
The present invention is in state shown in Figure 2 during bench drill start work when work, power switch 2 is in closure state with emergency stop switch 1, and guard shield is closed, goggle 4 closures.Goggle seat 3 is installed on the collar bush, and when collar bush moved up and down, goggle 4 and goggle seat 3 moved with collar bush.During bench drill work, navigation button 42 gets into locating hole 32, has avoided the influence of the gap of bench drill vibrations generations to second microswitch, and auxiliary simultaneously goggle 4 forwards suitable operating position to.This moment, paw 8 was depressed contact 7, and second microswitch is a "on" position, the machine operate as normal.
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.Open goggle 4, paw 8 rotates with goggle 4, and after paw 8 produced from contact 7 contacted positions arc groove 9 in, paw 8 did not contact with contact 7, and second microswitch is in off-position, machine down at this moment.
Boss 51 is pushed down contact-making surface 6, thereby makes the second microswitch fixed-site.
Second microswitch is off-position under normal condition, and stressed is "on" position when closed.
In the course of work of bench drill, open guard shield, open goggle 5, close emergency stop switch 1 or powered-down switch 2, can both make machine down, played the security protection effect more effectively.
