Background

Drilling refers to the operation of machining a hole in a solid material with a drill bit. In the prior art, when drilling a plate, in order to realize fixed point drilling of the plate, it is generally required that a drill can move in three directions of up and down, left and right, and front and back of a processing table, after the plate is placed on the processing table, the drill can reach above a position on the plate where drilling is required through the movement of the drill in the front and back and left and right directions of the processing table, and then the drilling operation of the plate is completed through the up and down movement of the drill, so that slide rails need to be arranged in the length direction and the width direction of the processing table, the movement of the drill in the front and back direction is realized by the slide rails in the length direction of the processing table, and the slide rails in the width direction are used for realizing the movement of the drill in the left and right direction of the processing table.

In the prior art, in order to reduce the workload of workers, a controller is generally adopted to control the drill bit to move on a processing table, and when drilling, after a plate to be processed is placed on the processing table by a worker, parameters of the drill bit to move are input through a control panel, the controller can control the drill bit to move according to the input parameters, so that the plate is drilled. However, in the drilling process, once the drill bit is found to be out of order, the drill bit needs to be stopped in time, and if the worker is not beside the processing table, the drill bit cannot be closed in time, so that the worker is required to be always beside the processing table, and thus, the moving range of the worker is limited, the worker is inconvenient to work, and drilled debris can splash around in the drilling process, and the drill bit can cause damage to the worker beside the processing table.
