[0002] Countersinking is a metal processing process, which is mainly used to improve the shape and size of the hole to better accommodate the screw head or nut. The purpose of countersinking is to ensure the perpendicularity between the hole mouth and the center line of the hole, and to ensure the correct position of the parts connected to the hole. The distance between the drill bit of the traditional countersinking device and the processing material is difficult to adjust. When adjusting, multiple parts need to be screwed to adjust the distance between the drill bit of the countersinking device and the processing material. This adjustment method is inconvenient to operate and affects work efficiency. Utility Model Content

[0008] As a further solution of the utility model: an electric box is fixedly installed on one side of the top plate, a countersink is installed below the electric box, and a hand wheel is installed on one side of the electric box.

[0009] As a further solution of the utility model: a counterweight block is fixedly installed above the base, and a collecting trough is fixedly installed at one end of the base away from the counterweight block.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] 1. The countersinking device for mechanical processing is provided with a pressure plate, a spring, a clamping block, a pulley and a slide rail. When the device is used, the pressure plate is squeezed according to the thickness of the material, and the pressure plate squeezes the spring to drive the clamping block to disengage from the limiting hole 1, and the pulley moves upward or downward on the slide groove. According to the preset height, the pressure plate is released, and the spring rebounds to drive the clamping block to engage in the limiting hole 1. This adjustment method abandons the need for the traditional countersinking device to screw multiple parts to adjust the distance between the drill bit of the countersinking device and the processing material, and the operation is convenient and the work efficiency is improved.

[0012] 2. The countersinking device for mechanical processing is provided with a water tank, a water injection hole, a water pump, a hose and a water outlet. When countersinking is performed, the high-speed rotation of the countersink drill will generate dust or metal waste. Clean water is added to the water tank through the water injection hole, the water pump is started, and the water outlet is aligned with the drilling position. The water pump draws water from the water tank and then sprays water mist from the water outlet through the hose, which effectively prevents dust or metal waste from spreading in the air and preventing dust or metal waste from being spread into the air and inhaled by workers, thereby improving practicality.
