Description

Technical Field

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

[0002] The grinding and polishing device is a kind of equipment specially used for fine processing of the surface of various materials. By adjusting the parameters such as grinding pressure, rotation speed, grinding and polishing time, the surface of the workpiece can be ground to remove defects, flatten the surface, and then polish to improve the finish. The surface of the workpiece can achieve the ideal smoothness, flatness and glossiness. It is widely used in many fields such as metal processing, jewelry manufacturing, optical lens production, etc. to meet the high-quality product surface processing requirements.

[0003] When the existing grinding and polishing device performs grinding and polishing on the surface of the workpiece, it is usually only possible to process one side at a time. After the processing is completed, the workpiece needs to be turned over before processing the other side. After the grinding process, the polishing head needs to be reinstalled to polish the workpiece. This processing efficiency is low, which affects the efficiency of the workpiece processing. In addition, when grinding and polishing the workpiece, the process of moving the grinding head or the polishing head is inconvenient. In order to solve the shortcomings of the prior art, we propose a double-sided grinding and polishing device. Summary of the invention

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

[0017] 2. In the present invention, the grinding disc and polishing disc provided allow the device to grind the workpiece without the need to disassemble the grinding disc and then reinstall the polishing disc, making the polishing process after grinding more convenient, saving time, and making the polishing process more efficient, eliminating the process of disassembling the grinding disc and installing the polishing disc, making the polishing process operation simpler and more convenient, and also making the workpiece processing more efficient.

[0018] 3. In the present invention, the threaded rod, No. 1 rotating rod, movable base plate, No. 2 slide rail and No. 2 rotating rod provided can make the moving operation of the two groups of grinding discs more convenient, the moving process is more stable, and the grinding discs can move in a wider range, which is convenient for people to control the movement of the grinding discs and the process of grinding the workpiece surface. The No. 1 rotating rod rotates to drive the two groups of movable base plates to move synchronously in the same or opposite directions at the upper end of the working platform, making it convenient for people to control the distance between the grinding discs and the workpieces and the contact force with the workpieces. Each group of No. 1 sliding blocks is respectively controlled to move by a group of No. 2 screw rods. When the two groups of No. 1 sliding blocks move synchronously in the same direction in the middle of the No. 2 slide rail, the grinding disc will translate. When the two groups of No. 1 sliding blocks move asynchronously in the middle of the No. 2 slide rail, the grinding disc will move up and down in height and adjust to multiple positions, and the moving process of the grinding disc is more convenient.

[0019] 4. In the present invention, the sliding rod, No. 2 sliding block, No. 1 screw rod, connecting block, No. 3 slide rail and No. 3 sliding block can make the movement process of the polishing disc smoother, the movement operation of the polishing disc more convenient, and the movement range of the polishing disc is wider, so as to achieve better polishing effect on the workpiece. The telescopic activity of the No. 1 cylinder can drive the two groups of polishing discs to move synchronously in the same direction or in the opposite direction through the No. 3 rotating rod, and control the distance between the polishing disc and the workpiece surface. When the No. 2 mounting frame is lifted and lowered by the lifting frame and the No. 2 cylinder, the height of the polishing disc can be adjusted. When the No. 1 screw rod rotates, it can drive the two groups of polishing discs to move forward and backward. In this way, the polishing disc can be moved to multiple positions, and the moving operation is also very simple and convenient.

[0020] 5. In the present invention, the No. 1 hair dryer and the No. 2 hair dryer can cool the surface of the workpiece and remove the dust and debris generated by the grinding or polishing process. When the grinding disc or the polishing disc rotates and rubs against the surface of the workpiece at high speed, a higher temperature will be generated, which will affect the properties of the workpiece to a certain extent and will also affect the service life of the polishing disc and the No. 2 hair dryer. The polishing disc and the No. 2 hair dryer cool them by wind power, which can prevent the surface properties of the workpiece from changing, better ensure the quality of grinding and polishing, and provide cooling protection for the grinding disc and the polishing disc to extend their service life. At the same time, the No. 1 hair dryer and the No. 2 hair dryer can also remove dust and debris to prevent these dust and debris from affecting the effect of grinding and polishing.

[0021] 6. In the present invention, the dust suction port, dust collection box and vacuum fan can absorb and collect the dust dropped during the grinding and polishing process, preventing dust debris from spreading in the air and affecting the air environment near the device and people's health, so that people can have a better air environment when operating, and keep the upper end of the working platform clean and tidy, making it more convenient to clean.

[0022] 7. In the present invention, the No. 4 slide rail, No. 4 slider and fastening bolts can conveniently allow the fixed clamp to slide on the upper end of the No. 4 slide rail, so that the fixed clamp can adjust its position according to the size of the workpiece and adapt to the sizes of different workpieces. The use range is wider, and workpieces of different sizes can be conveniently fixed, making the grinding and polishing process more convenient. The springs also make it very simple and convenient for the fixed clamp to fix the workpiece. BRIEF DESCRIPTION OF THE DRAWINGS
