Description

Technical Field

[0001] The present invention relates to the technical field of grinding machines, in particular to a Fancheng method grinding head structure and a grinding machine. Background Art

[0002] Currently, the Fancheng method's grinding head structure is typically driven by a three-phase asynchronous motor, which is then transmitted to the grinding head spindle via a belt, thereby driving the grinding wheel. The height and generatrix of the grinding wheel center and the workpiece are adjusted using three pivot points on the base plate. This adjustment process is complex and results in poor accuracy. Summary of the Invention

[0003] In order to solve the above technical deficiencies, the present invention provides a Fancheng method grinding head structure and a grinding machine, which can quickly and conveniently adjust the center height and angle of the grinding wheel.

[0004] The present invention discloses a Fancheng method grinding head structure, comprising a grinding head box, a grinding head rotating shaft provided on the grinding head box, a limiting mechanism provided between the grinding head rotating shaft and the grinding head box, a grinding head bracket shell fixed to the end of the grinding head rotating shaft, a grinding head shaft provided on the grinding head bracket shell away from one end of the grinding head rotating shaft, the grinding head shaft and the grinding head rotating shaft are perpendicular to each other, a pulley shell is sleeved on the grinding head shaft through a bearing, the pulley shell and the grinding head shaft are rotatably connected, a grinding wheel is fixed at the end of the pulley shell, a power motor is provided on the grinding head bracket shell between the grinding head shaft and the grinding head rotating shaft, a pulley is provided on the output shaft of the power motor, and a belt is wound between the pulley and the pulley shell.

[0005] In the above solution, the pulley housing on the grinding head shaft is driven to rotate by the pulley and belt on the power motor, and the pulley housing and the grinding head shaft are connected by a bearing. Therefore, the pulley housing rotates with high precision, and the grinding wheel rotates with high precision. In addition, the power motor is a synchronous motor, which can stably and efficiently transmit power to the grinding wheel, thereby improving the cutting power of the grinding wheel. At the same time, through the design of the grinding head rotating shaft, the grinding wheel angle can be adjusted by adjusting the angle of the grinding head rotating shaft, which is simple, convenient and highly precise. In order to increase the transmission stability between the belt, the pulley and the pulley housing, the inner surface of the belt can be provided with a pattern or texture, and the outer surfaces of the pulley and the pulley housing are correspondingly provided with a concave pattern or texture, so that the transmission is stable and the friction is large during the matching process.

[0006] The grinding head box is fixed on a wedge-shaped support plate mechanism, and the wedge-shaped support plate mechanism includes a wedge-shaped upper support plate and a wedge-shaped lower support plate. A slide rail is provided between the upper wedge-shaped support plate and the lower wedge-shaped support plate, and a linear motor is provided between the upper wedge-shaped support plate and the lower wedge-shaped support plate. The linear motor drives the upper wedge-shaped support plate and the lower wedge-shaped support plate to cause relative displacement along the slide rail. The upper wedge-shaped support plate and the lower wedge-shaped support plate have different thicknesses at both ends in the length direction, that is, the upper and lower surfaces are not parallel, and when the upper wedge-shaped support plate and the lower wedge-shaped support plate are matched, the ends with larger thicknesses of the two are respectively located at the two ends after matching, and are connected by the slide rail. Therefore, when the linear motor drives the two to cause relative displacement, the distance between the upper surface of the upper wedge-shaped support plate and the lower surface of the lower wedge-shaped support plate will change, thereby changing the height of the grinding head box on the upper wedge-shaped support plate, and finally adjusting the center height of the grinding wheel. The adjustment process is simple and convenient. The magnetic plate part and the coil part of the linear motor can be fixed on the wedge-shaped upper supporting plate and the wedge-shaped lower supporting plate respectively, ensuring that the linear motor can drive the two to move relative to each other along the direction of the slide rail.

[0007] A lubrication channel is provided within the grinding head shaft, extending from the end of the shaft without the grinding wheel to the bearing. An oil-gas connector is provided on the lubrication channel at the end of the shaft for connecting to a lubricating oil supply mechanism. Because the grinding head shaft is fixed and does not rotate, a lubrication channel can be provided within the shaft, extending to the bearing. The lubricating oil supply mechanism can be an oil mist lubricator, which generates oil mist that is transferred through the lubrication channel to the bearing for lubrication, thereby ensuring the bearing's life during high-speed operation.

[0008] A limiting disk is provided at the end of the grinding head rotating shaft, and the grinding head bracket shell is fixed on the limiting disk. The limiting mechanism is as follows: an inner concave notch is provided on the edge of the limiting disk, and a fixed block is provided on the grinding head housing corresponding to the inner concave notch. The fixed block is located inside the inner concave notch, and there is a gap between the edge of the fixed block and the edge of the inner concave notch. Screw holes are provided on the limiting disk on both sides of the inner concave notch, and tightening bolts are provided in the screw holes. The ends of the tightening bolts press against the fixed block. The design of this structure can adjust the angle of the grinding head rotating shaft by matching the positions of the tightening bolts on both sides of the inner concave notch with the screw holes, and fine-tune its position. The ends of the two tightening bolts after adjustment always press against the fixed block. The position of the grinding head rotating shaft can be limited, so the angle of the grinding wheel is fixed during operation to ensure processing accuracy and processing stability. Moreover, the above structure is simple and convenient for adjusting the angular position of the grinding head rotating shaft.

[0009] A coolant channel is provided inside the grinding head shaft, extending axially through the shaft. A coolant connector is provided on the coolant channel at the end of the shaft where the grinding wheel is not located. This connector delivers coolant through the channel to the grinding wheel, achieving continuous and effective cooling of the grinding wheel.

[0010] A sealing cover is provided on the grinding head support housing. The grinding head support housing and the sealing cover form a hollow cavity. The pulley, belt, and partial pulley housing are located within the hollow cavity. An air connector is provided on the grinding head support housing. The air connector is connected to a high-pressure air source and is used to create air pressure within the grinding head support housing to prevent the ingress of impurities and water. This structural design can enclose components such as the belt within the grinding head support housing and the sealing cover. During operation, it can effectively prevent coolant that washes onto the grinding wheel from entering the interior and coming into contact with the belt, thereby affecting the belt's operating condition and service life, thereby ensuring the stability of equipment operation.

[0011] A Fancheng method grinding machine using the aforementioned grinding head structure comprises a frame, a material clamping mechanism disposed on the frame, and a grinding head structure. The material clamping mechanism disposed on the frame includes a displacement mechanism oriented in the same direction as the linear motor. When the grinding wheel height of the grinding head structure is adjusted, the position of the linear motor in the direction of motion also changes accordingly. The material clamping mechanism can then drive the material to be repositioned accordingly, ensuring that the relative position of the material and the grinding wheel remains unchanged. Furthermore, a motion mechanism disposed on the frame, perpendicular to the linear motor's direction of motion, drives the wedge-shaped support mechanism and the grinding head structure above it toward or away from the material, thereby enabling processing of the material.

[0012] The Fancheng method grinding head structure and grinding machine obtained by the present invention can realize rapid and accurate adjustment of the grinding head height, and can also adjust the grinding wheel angle, and are convenient and simple to operate. BRIEF DESCRIPTION OF THE DRAWINGS
