Description

Technical Field

[0001] The utility model relates to the technical field of drilling machine protection, in particular to a protection component and a drilling machine thereof. Background Art

[0002] A drilling machine refers to a machine tool that mainly uses a drill to process holes on a workpiece. Usually, the drill bit rotates as the main movement. The drilling machine has a simple structure and relatively low processing accuracy. It is a general-purpose machine tool with a wide range of uses. Drilling machines are regularly inspected and maintained by professional maintenance personnel once a year or once every six months.

[0003] When a drilling machine is drilling, a lot of metal debris is ejected. The bench drills currently used generally do not have protective components to protect both sides of the bench drill when the drill bit falls. Manual attention is required to adjust the protective structure, which is inconvenient. Therefore, a new protective component is needed. Utility Model Content

The purpose of this arrangement is: by setting a proximity switch, the drill bit can be close to the proximity sleeve when it falls to a certain height, thereby opening the electric telescopic rod, so that the two protective vertical plates slide in the guide slide groove, the two protective vertical plates block the two sides of the drilling machine body to prevent metal debris from flying out, and the other direction of the drilling machine body is blocked and protected by inserting a protective baffle. When the drilling operation is completed, the proximity sleeve is away from the proximity switch, and the proximity switch controls the electric telescopic rod to reset, so that the two protective vertical plates are away from the drilling machine body, which is convenient for adjusting the workpiece after the operation and then drilling or removing the workpiece.

[0006] Preferably, a positioning pin is fixedly provided on one end of the lower surface of the two protective baffles, and the two positioning pins are interlaced and connected with the protective vertical plates that are located opposite to each other.

[0007] Preferably, a U-shaped positioning block is provided on the top of one side of each of the two protective vertical plates, and a positioning top plate is inserted between the two U-shaped positioning blocks.

[0008] Preferably, a protective top plate is fixedly connected to one side of the positioning top plate, and two positioning screws are interspersed and connected between the positioning top plate and the U-shaped positioning block.

[0009] Preferably, both ends of each of the positioning screws extend to the outside of the U-shaped positioning block and are threadedly connected with a positioning nut. The purpose of this arrangement is: the protective baffle can be disassembled and cleaned by means of the positioning pin, the positioning top plate is limited by means of the U-shaped positioning block, the positioning screw and the positioning nut, and the gap between the upper surfaces of the two protective vertical plates is blocked by means of the positioning top plate and the protective top plate to prevent debris from flying out.

[0010] Another object of the utility model is to provide a drilling machine, wherein the drilling machine comprises the protective assembly as described above.

[0011] Technical effects and advantages of the utility model:

[0012] (1) The device can be provided with a proximity switch so that when the drill bit falls to a certain height, it can approach the proximity sleeve, thereby opening the electric telescopic rod, allowing the two protective vertical plates to slide in the guide slide groove. The two protective vertical plates shield the two sides of the drilling machine body to prevent metal debris from flying out, and the other side of the drilling machine body is shielded and protected by plugging in a protective baffle. When the drilling operation is completed, the proximity sleeve moves away from the proximity switch, and the proximity switch controls the electric telescopic rod to reset, so that the two protective vertical plates move away from the drilling machine body, which is convenient for adjusting the workpiece after the operation and drilling or removing the workpiece. This solves the problem that the bench drills currently used generally do not have a protective component to protect the two sides of the bench drill when the drill bit falls, and manual attention is required to adjust the protective structure.

[0013] (2) The protective baffle can be disassembled and cleaned by means of a positioning pin, and the positioning top plate can be limited by means of a U-shaped positioning block, a positioning screw and a positioning nut. The positioning top plate and the protective top plate can block the gap between the upper surfaces of the two protective vertical plates to prevent debris from flying out.
