Description

Technical Field

[0001] This utility model relates to the field of burr removal and polishing technology, specifically to a burr removal and polishing device for machine tool cutting. Background Technology

[0002] Burrs are tiny metal protrusions or tear marks that form on the edges, holes, or surfaces of parts during machining. They are irregular in shape, usually with sharp edges or thin flakes, and may pose safety hazards or functional problems. Main causes include: Cutting processes: In turning, milling, drilling, etc., material tearing occurs when the tool separates from the workpiece, forming burrs. Plastic deformation: In stamping, forging, bending, etc., uneven metal flow causes edges to curl. Casting defects: Burrs are generated at the parting line of a mold due to the flow or cooling contraction of molten metal. Material characteristics: Brittle materials (such as cast iron) are prone to chipping burrs, while tough materials (such as aluminum alloys) may form rolled burrs due to stretching. Traditional burr removal involves workers using handheld grinding equipment to remove burrs through friction. However, traditional methods cannot reach into the bore or narrow space to remove small burrs inside tool holes.

[0003] For example, the application with application number "202321387245.5" cannot grind burrs in narrow spaces, and there is no monitoring of the operation of the entire machine during grinding. For example, during grinding, the shape of the tools being ground inside the grinding box may be different or the weight may exceed the standard, causing the local center of gravity of the grinding box to be too large, which will cause abnormal vibration of the entire grinding unit. If not intervened in time, it is easy to cause damage to the grinding equipment.

[0004] Therefore, a burr removal and grinding device for machine tool cutting is needed to address this problem. Utility Model Content

[0005] The purpose of this invention is to provide a burr-removing and grinding device for machine tool cutting tools. First, the cutting tool to be ground is placed into the grinding chamber. Then, the motor is started by pressing a start button, causing the grinding chamber to rotate. Silicon carbide or ceramic particles filled inside the grinding chamber then grind the burrs in the holes or grooves of the cutting tool. A vibration sensor monitors the vibration data of the entire device. If abnormal vibration occurs, an audible and visual warning device is activated, and the control unit stops the motor, allowing for timely intervention by the operator. The locking cover can be opened promptly to check if the cutting tool is stuck or if the weight is unevenly distributed within the grinding chamber. This invention not only grinds in small, narrow spaces but also provides timely warnings of unexpected situations during the grinding process. It is simple, convenient, quick, and highly practical.

[0006] This utility model is implemented as follows:

[0007] A burr-removing and grinding device for machine tool cutting tools includes a frame, bearing seats fixed on both sides of the frame, a grinding box rotatably mounted between the bearing seats on both sides via a rotating rod, a motor mounted on the frame at the bottom of the grinding box, a pulley mounted on the outer end of the rotating rod, and the rotating wheel of the motor being connected to the pulley via a belt.

[0008] A protective cover is provided on one side of the motor, and a control box is fixed to the top of the protective cover by a support rod. A swing door is provided on one side of the control box.

[0009] The control box is equipped with a motor start / stop button, which is connected to the motor.

[0010] A display screen is provided above the motor start / stop button, an audible and visual warning device is provided at the top of the control box, a vibration sensor is provided on the frame at the bottom of the bearing seat, and a control processing unit is provided inside the control box. The vibration sensor is connected to the input terminal of the control processing unit, and the motor, display screen and audible and visual warning device are all connected to the output terminal of the control processing unit.

[0011] Furthermore, the control processing unit adopts an STM32 control processor, and the grinding box is provided with a tool inlet, which is equipped with a locking cover.

[0012] Furthermore, the grinding chamber is filled with silicon carbide particles or ceramic particles. The particle size of the silicon carbide particles or ceramic particles is 10-20 mesh. 10-20 mesh particles can enter into small pores and grind burrs in narrow spaces.

[0013] Compared with existing technologies, the advantages of this invention are as follows: The tool to be sharpened is placed into the sharpening box, and the motor is started by pressing the start button. The motor drives the sharpening box to rotate, and the silicon carbide or ceramic particles filled inside the sharpening box sharpen the burrs in the holes or grooves of the tool. A vibration sensor monitors the vibration data of the entire device. If abnormal vibration occurs, an audible and visual warning device is activated, and the control unit stops the motor, allowing for timely intervention by staff. The locking cover can be opened promptly to check if the tool is stuck or if the weight is unevenly distributed within the sharpening box. This invention not only sharpens in small, narrow spaces but also provides timely warnings of unexpected situations during sharpening. It is simple, convenient, quick, and highly practical.
