[0002] Power tools are a kind of mechanical tools that use an electric motor or an electromagnet as power and drive the working head through a transmission mechanism to perform operations; common power tools include electric drills, electric grinders, electric wrenches, electric screwdrivers, electric hammers, impact electric drills, concrete vibrators, and electric planers; among them, the drill bit of an electric drill also belongs to the category of tools. During the use of the main cutting edge and the chisel edge of the drill bit, they will become dull or even chipped with the increase in the number of uses. In order to protect the cutting edge and extend the service life of the drill bit, the main cutting edge and the chisel edge of the drill bit often need to be ground after the drill bit is processed and formed.

[0003] Referring to the patent with the publication number CN216327035U, a drill bit edge grinding device is disclosed, including a workbench, a stepping motor, and a grinding tool. Support columns are arranged at the four corners of the lower end of the workbench, and a backing plate is installed at the lower end of the support columns. An operation panel is arranged on one side of the upper end of the workbench, a support frame is arranged on one side of the operation panel, and the stepping motor is arranged on one side wall of the support frame. The beneficial effects are as follows: The utility model adopts the design of clamping parts, sliding grooves, adjusting rods, and locking bolts, and can adjust the contact area between the grinding tool and the drill bit edge according to needs, and then fix the grinding tool through the locking bolt, so that the grinding quality can be effectively controlled to ensure the grinding quality of the drill bit. With the design of the stepping motor, the drill bit is driven by the stepping motor to rotate forward and backward at high speed, so that the grinding tool reciprocates and grinds inside the edge, greatly improving the grinding efficiency.

[0004] During the use of the above-mentioned device for grinding tools, some dust and debris will be generated. Due to the lack of a dust removal structure, the dust will spread to the surrounding area, polluting the environment or endangering human health.

The concave part of the crankshaft 9 is movably connected to a push rod 14 through a connecting piece 13, and the push rod 14 is arranged in the water storage chamber. At the bottom inside the water storage chamber, there is a pump cylinder 15. One end of the push rod 14 is connected to a piston 16 inside the pump cylinder 15. On one side of the top of the pump cylinder 15, there is a water inlet, and a one-way valve is arranged inside the water inlet. One end of the pump cylinder 15 is connected to a spray head through a conduit with a one-way valve, and the spray head is arranged on one side of the grinding tool 24, and the spray head is fixedly connected to the connection component. One end of the air duct 8 is connected to a dust suction hood 28 through a connecting pipe, and the dust suction hood 28 is fixedly installed on the inner rear wall of the box body 2.

[0024] The working principle of the present utility model: When in use, one end of the tool to be polished is clamped and fixed by the three-jaw chuck 5, and then the motor 4 can drive the three-jaw chuck 5 to rotate, and the grinding tool 24 is brought into contact with the tool, so as to polish it. At the same time, the operation of the motor 4 will drive a bevel gear II 11 connected to the output end, so that the bevel gear II 11 drives the bevel gear I 10 meshing with it to drive the crankshaft 9 to rotate. The crankshaft 9 will drive the fan blade 12 to rotate, generating a suction force, so as to cooperate with the dust suction hood 28 to suck the dust generated by grinding into the air duct 8 and intercept it through the filter screen. Part of the intercepted and fallen dust will be collected into the collection box 17, and the filtered air is discharged through the bottom of the base 1. When the crankshaft 9 rotates, it will drive the connecting member 13, so that the connecting member 13 drives the push rod 14, so that the push rod 14 continuously pushes and pulls the piston 16 to move in the pump barrel 15, so that the water entering the pump barrel 15 is transported into the conduit and then sprayed out through the nozzle to wash, cool and lower the temperature of the grinding tool 24 and the tool, preventing it from being damaged due to frictional heating, and at the same time avoiding the need for the tool to be statically cooled after grinding, improving the processing efficiency of the tool, and being able to process grinding waste and dust. At the same time, the washing water can be filtered and recycled to save water. At the same time, its linkage method reduces energy consumption and reduces costs. When the push rod 14 moves, it will drive the transmission rod 22 to drive the extrusion rod 23 to move, so that the upper end of the extrusion rod 23 squeezes and pushes the ejector rod 21 to push the knocking head 20 to move upward, so that the knocking head 20 impacts the filter screen in the filter frame 18 to vibrate, preventing the filtered dust and other sundries from accumulating and blocking to affect its filtering effect. When the grinding tool 24 is worn and needs to be replaced, the handle can be rotated to drive the bidirectional screw rod 26 to rotate, so that the bidirectional screw rod 26 synchronously drives the two fixing blocks 27 to move in the relatively outer direction, so that one end of the fixing block 27 inserted into the jack is removed, and the disassembly of the grinding tool 24 can be completed, which is convenient to use and has stronger practicability.

[0025] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features.
