Description

Technical Field

[0001] The present invention relates to the technical field of grinding and polishing, and particularly relates to a double-sided grinding and polishing device. Background Art

[0002] A grinding and polishing device is a device specifically used for fine processing of the surfaces of various materials. By adjusting parameters such as grinding pressure, rotation speed, and grinding and polishing time, operations such as grinding to remove defects and flatten the surface of the workpiece, and then polishing to improve the surface finish can be carried out on the surface of the workpiece in sequence, so that the surface of the workpiece can reach an ideal smoothness, flatness, and glossiness, and it is widely used in many fields such as metal processing, jewelry manufacturing, and optical lens production to meet the high-quality surface process requirements of products.

[0003] When the existing grinding and polishing device processes the surface of the workpiece, usually only one side can be processed at a time. After the processing is completed, the workpiece needs to be turned over and then the other side is processed. And after the grinding process, the polishing head needs to be reinstalled to polish the workpiece. In this way, the processing efficiency is relatively low, which affects the processing efficiency of the workpiece. Moreover, when grinding and polishing the workpiece, the movement process of the grinding head or the polishing head is not convenient. To solve the deficiencies of the existing technology, we propose a double-sided grinding and polishing device. Summary of the Invention

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In the present invention, the two groups of grinding discs and polishing discs provided can simultaneously grind and polish the outer surfaces of both sides of the workpiece. In this way, the grinding and polishing efficiency of the workpiece surface is higher, and there is no need to turn the workpiece over. At the same time, processing both sides of the workpiece can save more time, and the grinding and polishing effects on both sides of the workpiece can be better controlled, so that the grinding and polishing degrees on both sides of the workpiece can be better kept consistent, and the quality of the processed workpiece is better.

[0017] 2. In the present invention, the provided grinding disc and polishing disc enable the device, after grinding the workpiece, not to disassemble the grinding disc and then reinstall the polishing disc, making the polishing process after grinding more convenient, saving time, and also making the polishing process more efficient. The process of disassembling the grinding disc and installing the polishing disc is omitted, making the polishing operation simpler and more convenient, and also making the processing efficiency of the workpiece higher.

[0018] 3. In the present invention, the provided threaded rod, first rotating rod, moving bottom plate, second slide rail, and second rotating rod can make the movement operation of the two groups of grinding discs more convenient, the movement process more stable, and also enable the grinding discs to have a wider range of movement, facilitating people to control the movement of the grinding discs and the grinding process of the workpiece surface. The first rotating rod rotates to drive the two groups of moving bottom plates to move synchronously towards or away from each other at the upper end of the working platform, facilitating people to control the distance between the grinding disc and the workpiece and the contact force with the workpiece. Each first sliding block is controlled to move by a group of second lead screws. When the two first sliding blocks move synchronously in the same direction in the middle of the second slide rail, the grinding disc will perform a translation. When the two first sliding blocks move non-synchronously in the middle of the second slide rail, the grinding disc will perform up and down height movement and various position adjustments, making the movement process of the grinding disc more convenient.

[0019] 4. In the present invention, the provided slide bar, second sliding block, first lead screw, connecting block, third slide rail, and third sliding block can make the movement process of the polishing disc smoother, the movement operation of the polishing disc more convenient, and also make the movement range of the polishing disc wider, resulting in a better polishing effect on the workpiece. The telescopic movement of the first air cylinder can drive the two groups of polishing discs to move synchronously in the same or opposite directions through the third rotating rod, controlling the distance between the polishing disc and the surface of the workpiece. When the second mounting frame moves up and down through the lifting frame and the second air cylinder, the height of the polishing disc can be adjusted. When the first lead screw rotates, it can drive the two groups of polishing discs to move back and forth. In this way, the polishing disc can move to multiple positions, and the movement operation is very simple and convenient.

[0020] 5. In the present invention, the provided first hair dryer and second hair dryer can cool the surface of the workpiece and also remove the dust and debris generated during the grinding or polishing process. When the grinding disc or polishing disc rotates at high speed and rubs against the surface of the workpiece, a relatively high temperature will be generated, which will affect the properties of the workpiece to a certain extent and also affect the service life of the polishing disc and the second hair dryer. The polishing disc and the second hair dryer can be cooled by the wind force, preventing changes in the surface properties of the workpiece, better ensuring the quality of grinding and polishing, and also providing cooling protection for the grinding disc and the polishing disc, extending their service life. At the same time, the first hair dryer and the second hair dryer can also remove dust and debris, preventing these dust and debris from affecting the grinding and polishing effect.

[0021] 6. In the present invention, the provided dust suction port, dust collection box, and air extractor can absorb and collect the dust falling during the grinding and polishing process, preventing the dust and debris from spreading in the air, affecting the air environment near the device, and also preventing it from affecting people's physical health, making the air environment better during people's operation and keeping the upper end of the work platform clean, making it more convenient to clean.

[0022] 7. In the present invention, the provided fourth slide rail, fourth slider, and fastening bolt can conveniently make the fixed clamp block slide on the upper end of the fourth slide rail, allowing the fixed clamp block to adjust its position according to the size of the workpiece, adapting to workpieces of different sizes, with a wider range of use. Workpieces of different sizes can be conveniently fixed, making the grinding and polishing process more convenient. The provided spring also makes the operation of fixing the workpiece by the fixed clamp block very simple and convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] It should be noted that the present invention is a double-sided grinding and polishing device. When in use, the fixed clamping block 55 slides on the upper end of the fourth slide rail 54 through the fourth slider 59 to adjust the distance to adapt to the size of the workpiece. Then, the fastening bolt 63 is rotated to fix the fourth slider 59 to the fourth slide rail 54. One side of the fixed clamping block 55 is pulled outwards, and a plate-shaped or sheet-shaped workpiece is placed between the fixed clamping blocks 55. The fixed clamping block 55 fixes the lower end of the workpiece through the elastic force of the spring 62. Then, the first motor 14 on the upper end of the support plate 5 drives the threaded rod 15 to rotate at the lower end of the working platform 1. When the threaded rod 15 rotates, the first movable block 16 will move downwards on the outer wall of the threaded rod 15, and at the same time, drive the two groups of moving bottom plates 3 to move relatively synchronously on the upper end of the working platform 1 through the first rotating rod 17, so that the two grinding discs 29 contact the two side surfaces of the workpiece. The third motor 28 is started to drive the grinding discs 29 to rotate at a high speed, and the surface of the workpiece can be ground.

When the two first sliding blocks 19 in the middle of the second slide rail 13 move synchronously in the same direction, the grinding discs 29 will move back and forth. When the two first sliding blocks 19 do not move synchronously in the middle of the second slide rail 13, the grinding discs 29 will move in multiple positions to perform all-round grinding on the surface of the workpiece;

[0044] After grinding is completed, the grinding disc 29 leaves the surface of the workpiece. The first cylinder 41 extends upward, driving two groups of third sliding blocks 40 to move relatively in the middle of the third slide rail 39 through two groups of third rotating rods 43, so that the two polishing discs 48 contact the two side surfaces of the workpiece. The fifth motor 47 inside the second mounting frame 45 is started to drive the polishing disc 48 to rotate at a high speed, and the surface of the workpiece is polished. At the same time, the second hair dryer 49 is started to cool the polishing disc 48 and the surface of the workpiece. The telescopic movement of the second cylinder 46 can drive the polishing disc 48 to move up and down. The fourth motor 37 drives the first lead screw 10 to rotate, and the connecting block 36 will move on the outer wall of the first lead screw 10. Then, through the first connecting rod 35, the second sliding block 34 and the second connecting rod 38, the third slide rail 39 is driven to move back and forth, and then the two polishing discs 48 are driven to move back and forth, so that the polishing disc 48 can move in multiple positions to perform all-round polishing on the workpiece. During the polishing and grinding process, the air extractor 58 also keeps working, generating suction above the two dust suction ports 56 to suck the dust and debris generated during the grinding and polishing processes into the inside of the dust collection box 57.
