Description

Technical Field

[0001] The invention relates to the technical field of grinding head structures of flat plate polishers, and in particular to a swinging grinding head structure of a flat plate polisher. Background Art

[0002] A flat plate polisher is a mechanical device specially used for polishing the planes of various materials. It is widely used in the surface polishing of metal and non-metal materials, and can achieve a mirror effect or a specific surface roughness. The flat plate polisher drives the polishing head to rotate through an electric motor and generates friction with the surface of the workpiece. The cutting force generated by friction is used to grind the uneven surface of the workpiece flat, thereby achieving a polishing effect. During the polishing process, the polishing liquid can be sprayed through an automatic liquid spraying device to keep the polishing head moist and improve the polishing effect.

[0003] In the existing flat polishing machine, the grinding wheel only rotates relative to the parts during the grinding wheel polishing process, and the polishing part moves horizontally on the workbench to complete the surface polishing of the polishing part. The polishing wheel cannot swing left and right during polishing. When the polishing wheel position is adjusted, the polishing wheel and the unpolished part of the part are re-polished. The pressure of the subsequent polishing is different, which often causes lines along the horizontal movement direction of the polishing part between one polishing track and another polishing track, affecting the surface polishing effect. Therefore, a flat polishing machine swinging grinding head structure is needed to solve the above problems. Summary of the invention

[0015] The present invention has at least the following beneficial effects:

[0016] 1. By setting a grinding head assembly, the swinging and pushing grinding of the grinding wheel can be realized. Compared with the traditional structure, the device controls the rotation of the grinding wheel by driving the frame shaft to rotate through the shaft tube. When the grinding wheel rotates, it can drive the rotating shaft between the left buckle ring and the right buckle ring. At this time, the V-shaped return groove of the rotating shaft can cooperate with the guide block to control the rotating shaft to rotate left and right between the left buckle ring and the right buckle ring, and then control the grinding wheel to grind the parts in the swing. At this time, the parts are being pushed, and the grinding wheel can grind the parts without stopping, and the parts can be polished in a non-debugging state, which effectively reduces the probability of lines formed between one polishing track and another polishing track along the horizontal moving direction of the polished part in traditional grinding, thereby ensuring the polishing effect.

[0017] 2. By setting up an auxiliary grinding component, the grinding effect of parts is further improved. After the device grinds the flat plate parts with the grinding wheel, the movable block can be driven to move by the extension and retraction of the cylinder piston rod end, so that the movable block cooperates with the hanging plate to drive the docking shaft to dock with the first pulley. At this time, the docking shaft can drive the first bevel gear to rotate, and the first bevel gear and the second bevel gear can drive the air disk to rotate. Affected by the distribution of the counterweight plate, the end of the air disk generates high-frequency vibration. At this time, the sandpaper sleeve is arranged on the surface of the grinding pressure plate, and the high-frequency vibration of the grinding pressure plate is driven by the air disk, and then the sandpaper is driven to perform a flat and fine grinding operation on the surface of the flat plate, thereby further improving the grinding effect of the flat plate parts.

[0018] 3. By setting up the grinding head assembly, the stable disassembly and assembly of the grinding wheel can be achieved. The device removes the bolts of the left buckle and the right buckle. When the guide block is excessively worn, the right buckle and the guide block can be removed in turn and replaced. When disassembling and assembling the grinding wheel, the grinding wheel can be pulled outward, and then the frame shaft and the shaft tube are separated, which is convenient for disassembly of the grinding wheel. The slider can move in the plate frame guide groove, and the position of the right hanging plate can be changed to meet the installation of various types of grinding wheels and ensure the installation adaptability of the grinding wheel. By using various types of grinding wheels to grind the flat plate parts, the grinding effect of the flat plate parts will be further improved.

[0019] 4. By setting the pushing accessories, the parallel transmission of the docking shaft is realized. The device can control the movable block to move in the guide groove in the shaft bin through the extension and retraction of the piston rod end of the cylinder. The movement of the movable block can drive the movement of the hanging plate, and then control the docking shaft to be inserted into the polygonal groove on the right side of the first pulley, so that the first bevel gear can rotate synchronously, control the vibration of the grinding pressure plate, and facilitate the grinding of the flat plate parts by the grinding pressure plate and sandpaper. This design can complete the grinding and finishing operation without removing the flat plate parts. BRIEF DESCRIPTION OF THE DRAWINGS

A motor 43 is connected to the right side of the second pulley 42, and the motor 43 is installed on the side of the frame 1 by bolts.

[0035] An auxiliary grinding assembly 5 is arranged on the right side of the first pulley 37, and the auxiliary grinding assembly 5 includes a docking shaft 51, which is inserted into the right side of the first pulley 37 through a polygonal slot, and a first bevel gear 52 is connected to the right side of the docking shaft 51, and a second bevel gear 53 is meshed below the first bevel gear 52, and the shaft end of the second bevel gear 53 passes through the box body 57 and is connected to the wind disk 54, and a grinding pressure plate 56 is arranged at the bottom of the wind disk 54.

[0037] A pushing accessory 58 is provided at the top of the box body 57, and the pushing accessory 58 includes a hanging plate 581. The four corners of the bottom end of the hanging plate 581 are connected to the box body 57 through bolts. A movable block 582 is connected to the top of the vertical plate of the hanging plate 581. The movable block 582 is movably installed inside the shaft bin 583 through a guide groove.

[0038] The movable block 582 is composed of a column end and a plate end. A cylinder 584 is installed on the left side of the movable block 582, and the cylinder seat end of the cylinder 584 is installed on the left side of the shaft bin 583. The shaft bin 583 is fixed to the front side of the plate frame 1 by bolts.

[0039] The pull-out design of the frame shaft 34 and the shaft cylinder 36 can facilitate the grinding wheel 33 to be swung, pulled, disassembled and assembled left and right. The shaft cylinder 36 can be suspended by the right hanging plate 35 to prevent the grinding wheel 33 from tilting and falling during grinding. The left buckle 312 and the right buckle 314 are externally installed on the surface of the left hanging plate 311, which can facilitate the subsequent replacement of the grinding wheel 33. Replacing grinding wheels 33 of different models can meet the grinding of flat plate parts. By twisting the threaded rotating shaft 39, the slider 38 can be driven to translate in the guide groove of the plate frame 1, thereby controlling the displacement of the right hanging plate 35, and then controlling the position of the shaft cylinder 36, and controlling the frame The shaft 34 is inserted into the position inside the shaft cylinder 36, which is convenient for plugging, unplugging and assembling the grinding wheel 33. At the same time, the guide groove of the plate frame 1 can limit and guide the slider 38 to prevent the slider 38 from offset during movement. The columnar structure design on the surface of the slider 38 can ensure the smoothness of the slider 38 during movement. When the frame shaft 34 is connected to the shaft cylinder 36, the external spline of the frame shaft 34 cooperates with the internal spline of the shaft cylinder 36. When the first pulley 37 rotates, it can drive the shaft cylinder 36 to rotate. At this time, the shaft cylinder 36 can cooperate with the frame shaft 34 to drive the grinding wheel 33 to rotate, and then the grinding wheel 33 can be conveniently controlled to perform grinding and polishing operations on the flat plate parts.

[0040] The left buckle ring 312 and the right buckle ring 314 adopt a split design, which can facilitate the replacement of the guide block 313 after it is worn. When the rotating shaft 32 is inserted into the guide block 313 and the right buckle ring 314, the grinding wheel 33 can drive the rotating shaft 32 to rotate. The V-shaped return groove of the rotating shaft 32 cooperates with the guide block 313, which can make the grinding wheel 33 swing left and right, thereby ensuring the grinding and polishing effect of the flat plate parts and reducing the probability of straight line marks appearing on the grinding wheel 33 during grinding. The rotation of the second pulley 42 can be controlled by rotating the shaft end of the motor 43, so that the second pulley 42 cooperates with the connecting belt 41 to control the rotation of the first pulley 37, thereby controlling the rotation start and stop effect of the grinding wheel 33.

[0041] By plugging and docking the docking shaft 51 with the shaft cylinder 36, the first pulley 37 can synchronously drive the docking shaft 51 to rotate, and the synchronous rotation of the docking shaft 51 can be controlled. The docking shaft 51 and the second bevel gear 53 are both rotatably installed inside the box body 57 to prevent the docking shaft 51 and the second bevel gear 53 from lacking support during rotation. When the second bevel gear 53 rotates, it can drive the second bevel gear 53 to rotate, and then it is convenient to make the end of the wind disc 54 vibrate under the counterweight of the counterweight plate 55, so that the grinding pressure plate 56 can vibrate at a high frequency in a small range, and the sandpaper is installed on the grinding pressure plate 5 6 surface, the grinding plate 56 can be used to drive the sandpaper to grind and polish the flat plate parts. When the wind disc 54 rotates, the wind slot of the wind disc 54 can accelerate the air circulation in the box body 57, which has a certain cooling effect. The counterweight plates 55 on the surface of the wind disc 54 are unevenly distributed. The counterweight plates 55 are sparsely arranged on the left side of the top of the wind disc 54, and the counterweight plates 55 are tightly arranged on the right side, thereby changing the centrifugal force of the wind disc 54 during rotation. When the wind disc 54 rotates, the wind disc 54 can vibrate at a high frequency during rotation, which makes it convenient for the grinding plate 56 to cooperate with the sandpaper to grind the flat plate parts.

[0042] The movable block 582 can be controlled to move in the guide groove of the shaft bin 583 by extending and retracting the piston rod end of the cylinder 584, and then the connecting plate 581 drives the box body 57 to move, and the plug-in state of the docking shaft 51 and the polygonal groove of the first pulley 37 is controlled, so as to control the start and stop rotation state of the wind disk 54. The column end structure of the movable block 582 can ensure the smooth movement of the movable block 582 inside the shaft bin 583. The movable block 582 can be pushed by extending and retracting the piston rod end of the cylinder 584, and then the position of the connecting plate 581 is adjusted to control the plug-in state of the docking shaft 51 and the right side of the first pulley 37.

[0043] Working principle: According to the attached Figure 2 With attached Figure 3 As shown, during use, the flat plate component can be placed on the processing table, and the rotating shaft 32 can be inserted between the left buckle ring 312 and the right buckle ring 314, so that the guide block 313 is embedded in the guide groove of the rotating shaft 32, and the left buckle ring 312 and the right buckle ring 314 are fixed to the surface of the left hanging plate 311 by bolts. At this time, the threaded rotating shaft 39 is twisted, and the shaft end of the threaded rotating shaft 39 cooperates with the slider 38, and the slider 38 can be controlled to drive the right hanging plate 35 to move. The right hanging plate 35 can control the internal spline of the shaft cylinder 36 to dock with the external spline of the frame shaft 34 during the movement, thereby completing the assembly;

[0044] Secondly, according to the attached Figure 4As shown, the motor 43 is started, and the shaft end of the motor 43 can drive the second pulley 42 to rotate, so that the second pulley 42 cooperates with the connecting belt 41 to drive the first pulley 37 to rotate, and the first pulley 37 can drive the shaft cylinder 36 to rotate, and the shaft cylinder 36 cooperates with the frame shaft 34 to drive the grinding wheel 33 to rotate. At this time, the rotating shaft 32 on the left side of the grinding wheel 33 rotates between the right buckle 314 and the guide block 313, and the guide block 313 cooperates with the V-shaped return groove of the rotating shaft 32, so that the grinding wheel 33 can be controlled to swing left and right for rotation and grinding. At this time, the flat plate parts are pushed or the external driving device controls the overall displacement of the grinding device, and the grinding wheel 33 is controlled to grind the displacement in the swing. When the preliminary grinding is completed, according to the attached Figure 5 With attached Figure 6 As shown, extending and retracting the piston rod end of the cylinder 584 can drive the movable block 582 to move in the guide groove of the shaft warehouse 583, thereby changing the position of the hanging plate 581. The movement of the hanging plate 581 can drive the box body 57 to move, so that the docking shaft 51 is docked with the polygonal slot on the right side of the first pulley 37. When the first pulley 37 rotates, the docking shaft 51 can be driven to rotate, and the docking shaft 51 drives the first bevel gear 52 to rotate. The first bevel gear 52 cooperates with the second bevel gear 53 to drive the air disc 54 to rotate. Affected by the counterweight of the counterweight plate 55, the end of the air disc 54 vibrates and swings at a high frequency during rotation. At this time, the air disc 54 drives the sandpaper on the surface of the grinding pressure plate 56 to perform a grinding and finishing operation on the flat plate parts.
