Description

Technical Field

[0001] This utility model belongs to the field of cutting tool grinding technology, and in particular relates to a grinding device for machine tool cutting tools. Background Technology

[0002] CNC machine tool cutting tools are tools used for cutting and machining in mechanical manufacturing. They are also called cutting tools. Turning tools and milling cutters are two types of CNC cutting tools. During use, cutting tools often need to be ground with grinding equipment to ensure that the workpiece achieves the surface accuracy, dimensional accuracy and surface roughness required before polishing.

[0003] Existing grinding devices grind machine tool cutting tools by rotating a grinding wheel. During the grinding process, metal shavings are scattered throughout the working environment, which greatly affects the grinding of machine tool cutting tools. At the same time, prolonged grinding causes the surface temperature of the cutting tool and grinding wheel to rise, which will inevitably affect the grinding quality of the machine tool cutting tools.

Figure 2As shown, in the initial state, the air pressure cleaning unit 301 is set close to the inner wall of the sanding box 101. When the cleaning control motor 303 is started to drive the horizontal screw 304 to rotate, the air pressure cleaning unit 301 can be driven to reciprocate along the surface of the filter plate 103 by means of the threaded engagement between the horizontal screw 304 and the moving seat 306.

[0028] Furthermore, the air pressure cleaning unit 301 is disposed in the sanding chamber 104 and is attached to the top of the filter plate 103.

[0029] The grinding control motor 204 is started to slowly rotate the grinding wheel 201. The control system opens the solenoid valve 113 on the drain pipe 112, allowing water from the storage tank 111 to flow along the drain pipe 112 into the hollow drain section 108, and then out through the guide pipe 109 and the arc-shaped guide section 102 to the circumferential surface of the grinding wheel 201. This wets and cools the grinding wheel 201 through water flow. After closing the solenoid valve 113, the grinding control motor 204 controls the grinding wheel 201 to rotate rapidly. The operator holds a machine tool cutting tool, inserts it into the grinding chamber 104 through the grinding operation port 110, and presses it against the circumferential surface of the grinding wheel 201. The rotating grinding wheel 201 then performs the grinding process on the machine tool cutting tool. After a grinding period (set by the system), the operator... The operator removes the machine tool cutting tool from the grinding wheel 201 and controls the opening of the solenoid valve 113 again (while simultaneously controlling the grinding wheel 201 to rotate slowly again), so that the water in the water tank 111 flows along the diversion pipe 112 to the hollow diversion part 108, and then flows out through the guide pipe 109 and the arc-shaped guide part 102 to the circumferential side of the grinding wheel 201. In this way, the grinding wheel 201 is wetted and cooled again by the water flow. Then, the grinding wheel 201 is controlled to rotate rapidly again by the grinding control motor 204. The operator holds the machine tool cutting tool and inserts it into the grinding chamber 104 through the grinding operation port 110 and presses it against the circumferential side of the grinding wheel 201. The grinding wheel 201 rotates to achieve the grinding of the machine tool cutting tool. The same grinding control method is used until the grinding of the machine tool cutting tool is completed.
