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 4, the utility model discloses a kind of bench drill with dual crack safety device, comprise table drill body, collar bush, 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 2 are installed on the described table drill body, and described the first microswitch, the second microswitch, emergency stop switch 1 and power switch 2 are in series; Described protective glass device comprises goggle seat 3, goggle 4 and the second microswitch; Described the second microswitch is installed on the goggle seat 3, and goggle seat 3 is installed on the collar bush; Described goggle seat 3 is provided with hole 1, and goggle 4 is provided with hole 2 41, and hole 1 and hole 2 41 are suitable, and bolt connects goggle 4 and goggle seat 3 by hole 1, hole 2 41; Described the second microswitch comprises cover plate 5, contact-making surface 6, contact 7, paw 8, arc groove 9 and trough 10; Described cover plate 5 is connected mutually with goggle seat 3, and cover plate 5 is provided with boss 51, and boss 51 and contact-making surface 6 are suitable; Described goggle 4 is provided with paw 8, and described contact 7 is installed on the goggle seat 3, and goggle seat 3 is provided with arc groove 9, and arc groove 9 and paw 8 are suitable, and paw 8 and contact 7 are suitable; Also be provided with locating hole 32 and trough 10 on the described goggle seat 3, goggle 4 is provided with navigation button 42, and navigation button 42 and locating hole 32 are suitable.
In the present embodiment, described cover plate 5 is riveted on the goggle seat 3, and Rankine-Hugoniot relations was installed in the side of table drill body about described power switch 2 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 2 and emergency stop switch 1 are in closure state, 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 enters locating hole 32, has avoided the gap of bench drill vibrations generations on the impact of the second microswitch, and auxiliary goggle 4 forwards suitable operating position to simultaneously.This moment, paw 8 was depressed contact 7, and the second microswitch is "on" position, the machine normal operation.
