Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: a protective device for a drilling machine comprises a support 2, the middle of the support 2 is hollow, protective plates 1 are attached to the periphery of the support 2, limiting grooves 7 are formed in four corners of the upper end of the support 2, the limiting grooves 7 penetrate through the lower end of the support 2, a connecting frame 3 is arranged at the upper end of the support 2, the middle of the connecting frame 3 is hollow, limiting rods 4 are fixedly connected to four corners of the lower end of the connecting frame 3, the limiting rods 4 downwards extend through the limiting grooves 7, clamping blocks 8 are fixedly connected to the lower end of the limiting rods 4 and are located at the lower end of the limiting grooves 7, main springs 5 are sleeved outside the limiting rods 4 and between the support 2 and the connecting frame 3, the upper ends and the lower ends of the main springs 5 are respectively attached to the lower end of the connecting frame 3 and the upper end of the support 2, a sliding groove 10 is formed in the middle of the front side of the upper end of the support 2, a sliding rod 11 is provided with, the upper end of a sliding rod 11 is fixedly connected with a pressing sheet 6, the middle position of the front side of the lower end of a connecting frame 3 is fixedly connected with a contact switch 13, the contact switch 13 is positioned at the upper end of the pressing sheet 6, the lower end of a protection plate 1 at the rear end is provided with a chip removal hole 14, a limiting rod 4 is in sliding connection with a limiting groove 7, a sliding groove 10 is in sliding connection with the sliding rod 11, adjacent protection plates 1 are mutually attached, the protection plate 1 is made of hard transparent plastic, two contacts are arranged inside the contact switch 13, and the two contacts of the contact switch 13 are respectively electrically connected with a switch of a drilling machine and;

firstly, need install this device on the drilling machine, because support 2 and the 3 middle parts of splice frame are hollow, can be through the drill bit outside with splice frame 3 and support 2 cover at the drilling machine, and can be with splice frame 3 welding or through the bolt mounting on the shell of drilling machine, again with two contacts of contact switch 13 respectively with the switch electric connection of external power source and drilling machine, like this when the switch of starting the drilling machine, because contact switch 13 does not have pressed, so the drill bit can not rotate.

Afterwards, place the work piece on table surface and the centre gripping of drilling machine, through the handle on the rotation drilling machine after that, make the drill bit and install this device in the drill bit outside descend, because guard plate 1 is lower than the drill bit bottom, so that guard plate 1 lower extreme contacts the work piece earlier, at this moment guard plate 1 receives the extrusion of work piece, make guard plate 1 and support 2 can upwards remove, and then gag lever post 4 can be in spout 10 lapse, main spring 5 can receive the extrusion simultaneously, and slide bar 11 upper end rebound contacts can extrude contact switch 13 behind contact switch 13, make contact switch 13 switch-on external power and the connection of drilling machine, the drill bit just begins to rotate like this, and slide bar 11's upper end receives contact switch 13's restriction can extrude secondary spring 12 downwards, and slide downwards in spout 10.

After the drill bit rotates, the handle on the drilling machine continues to rotate, the drill bit continues to move downwards and starts to process the workpiece, the lower end of the protection plate 1 is kept to be tightly attached to the workpiece all the time, and therefore chips generated by the drill bit during processing of the workpiece can only fly out of the chip removal hole 14, and the chips which are splashed out cannot damage the drill bit.

After finishing waiting to process, through the handle on the antiport drilling machine, upwards shift the drill bit, wait that the drill bit moves to and to be higher than the lower extreme of guard plate 1, slide bar 11 moves to the upper end and makes lug 9 support the lower extreme of support 2, and then preforming 6 leaves contact switch 13, and contact switch 13 resets for the disconnection of drilling machine and external power, lead to the drill bit stall, just so reached and bored the effect of stopping promptly.
