Description

Technical Field

[0001] The invention relates to the field of magnetic grinding, and in particular to a flexible suspension type magnetic grinding and polishing device and method for non-magnetic thin plate parts. Background Art

[0002] Existing flat plate polishing machines are mostly used for online polishing of steel plates on large thin plate rolling production lines. This method is mostly grinding and polishing with a grinding wheel or abrasive belt, which has a large amount of material removal and a large grinding tool size, and is not suitable for polishing precision parts. In addition, due to the large size of the equipment, it is not suitable for small workpieces and single batch grinding and polishing.

[0003] Most of the existing devices for polishing planes based on magnetic grinding are modified from three-axis vertical CNC milling machines or table drilling machines. The principle of this type of device is: the permanent magnetic pole adsorbing magnetic abrasives is clamped on the machine tool spindle, and the workpiece to be polished is clamped on the workbench; a certain grinding gap is maintained between the permanent magnetic pole adsorbing magnetic abrasives and the polished plane; the machine tool spindle drives the permanent magnetic pole adsorbing magnetic abrasives to rotate, and at the same time, it generates a relative feed motion with the polished workpiece at a certain speed, thereby completing the grinding and polishing of the workpiece surface. In this processing model, the magnetic field force acts in the form of attracting magnetic abrasive particles, so that they overcome their own gravity, the mutual attraction between the abrasive particles, and the friction between the abrasive particles, and finally adsorb on the rotating permanent magnetic pole. The grinding pressure, one of the important factors in the grinding process, comes largely from the positive pressure between the machine tool spindle and the surface of the workpiece to be processed, which is a rigid force. When the grinding gap between the machine tool spindle and the surface of the workpiece to be processed is determined, the more magnetic abrasive particles are pressed between the machine tool spindle and the workpiece surface, the greater the grinding pressure. On the contrary, if the number of pressed magnetic abrasive particles is smaller, the grinding pressure is smaller. During the grinding process, the machine tool spindle drives the magnetic abrasive particles to rotate at high speed, so that the magnetic abrasive particles at the center of the pressed area move toward the outer edge of the spindle permanent magnetic pole, and finally adsorb on the outer edge of the spindle permanent magnetic pole or break away from the attraction of the spindle permanent magnetic pole and splash outward, resulting in a decrease in the number of pressed magnetic abrasive particles between the machine tool spindle permanent magnetic pole and the surface of the workpiece being processed, a decrease in grinding pressure, and a weakened grinding effect; when there are too many pressed magnetic abrasive particles between the machine tool spindle permanent magnetic pole and the surface of the workpiece being processed, or the plane of the workpiece being processed is not parallel to the extreme surface of the machine tool spindle permanent magnetic pole, the grinding pressure suddenly increases, resulting in deep scratches and other "ploughing" phenomena, which destroy the surface integrity of the workpiece and have a very poor grinding effect.

[0004] In summary, the surface grinding and polishing of thin plate workpieces are mostly done by grinding wheels or abrasive belts, which remove a large amount of material and have large grinding tools, making them unsuitable for polishing precision parts. The traditional vertical milling machine's magnetic plane grinding method has the disadvantages of sudden changes in grinding pressure, difficulty in control, uneven surface quality, and easy damage to the surface integrity of the workpiece. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a flexible suspended magnetic grinding and polishing device for non-magnetic thin plate parts, which solves the problems existing in the traditional vertical milling machine magnetic grinding plane method, such as the grinding pressure is difficult to control, the grinding surface quality is uneven, and the surface integrity of the workpiece is easily damaged.

[0044] The specific steps are as follows:

[0045] 1) Clamping: Fix the ground plate on the upper platform of the workbench cover box through the downward screw of the workpiece clamping mechanism;

[0046] 2) Suspension height adjustment: Install the cylindrical magnetic pole to be used on the connecting rod bracket, and adjust the length of the lower connecting rod bracket so that the cylindrical magnetic pole is 1-3mm away from the upper surface of the ground plate;

[0047] 3) Adding abrasive: Add magnetic abrasive (ferromagnetic abrasive particles mixed with an appropriate amount of water-based abrasive liquid) to the cylindrical magnetic pole suspended above the plate to be ground, so that it completely wraps the cylindrical magnetic pole;

[0048] 4) Set the processing speed: set the rotating permanent magnet speed in the rotating magnetic pole mechanism to 600-1000r / min, and set the feed speed of the X-axis moving mechanism to 1-3mm / s;

[0049] 5) Processing: Magnetic abrasive is pressed on the upper surface of the plate to be ground for grinding and polishing. The abrasive is replaced every 20-30 minutes, and 2-3 ml of grinding liquid is added to the grinding area every 10-15 minutes;

[0050] 6) Cleaning: Remove the ground workpiece, rinse with clean water, and then dry it.
