Description

Technical Field

[0001] The invention relates to the technical field of jewelry processing, in particular to a grinding device for jewelry processing. Background Art

[0002] Jewelry is loved by everyone. The shiny jewelry we see in jewelry stores, as well as various shapes and styles, are all completed through many procedures of processing, design, production, and polishing. Polishing is the last procedure of jewelry processing and also the most important one. The quality of polishing determines the quality and price of jewelry.

[0003] According to a jewelry processing and polishing device proposed by Chinese patent CN212794390U, the jewelry is placed between two rotating disks, and the operation of the electric push rod is started by a controller. The contraction of the electric push rod drives the two pressure plates to move toward each other to clamp the jewelry to be polished. Then, according to the degree of polishing required for the jewelry, the rotating handle is manually rotated, and the rotation of the handle drives the movement of the mounting block, and the movement of the mounting block drives the movement of the jewelry to be polished to adjust the most suitable polishing point of the jewelry to be polished and the polishing sheet. Then, the rotation of the motor is started by the controller, and the rotation of the motor drives the rotation of the polishing sheet. Then, the rotating disk is manually rotated, and the rotation of the rotating disk drives the movement of the mounting block. The movement of the mounting block makes the jewelry to be polished constantly approach the polishing sheet for polishing. After the polishing is completed, the motor is turned off and the polished jewelry can be removed.

[0004] However, there are still some shortcomings in this patent. In this device, the surface of the jewelry is polished by rotating the polishing plate. However, during the polishing process, since the fixed position of the jewelry is always unchanged, the polishing position is single during the polishing process, which makes it inconvenient to polish other positions on the surface of the jewelry, affecting the practicality of the device. For this reason, we propose a polishing device for jewelry processing. Summary of the invention

[0026] Working principle: Before the jewelry needs to be polished, in order to improve the stability of the jewelry polishing process, the jewelry needs to be fixed. At this time, the operator places the jewelry between the two displacement plates 3116, and then turns on the forward and reverse motor 319. After the forward and reverse motor 319 is started, the output shaft 3110 is prompted to rotate. After the output shaft 3110 rotates, the spur gear 3111 is prompted to rotate. After the spur gear 3111 rotates, it meshes with the rack 3112. Under the action of the T-shaped limit plate 3114 and the slide groove 3113 limiting the rack 3112, the two racks 3112 are prompted to get closer to each other, prompting the two limit rods 311 When the two limit rods 3115 are relatively close to each other, the displacement plates 3116 are relatively close to each other. Under the action of the corresponding clamping force of the two displacement plates 3116, the jewelry to be polished can be clamped and fixed.

When the rotation angle of the jewelry is adjusted, the operator releases the pull plate 3118, and the insertion rod 3117 is reset under the reaction of the spring 3119, causing the insertion rod 3117 to be inserted into the side of the clamping plate 3121 to limit the clamping plate 3121, thereby facilitating the fixing of the jewelry after the rotation angle is adjusted, and improving the stability of the jewelry during the polishing process. When the surface of the jewelry needs to be polished, the operator turns on the cylinder 328 to cause the fixing seat 329 to move downward. When the fixing seat 329 moves downward, the bottom of the polishing disc 3212 will fit the surface of the jewelry. Then, the operator turns on the second drive motor 3210 to cause the transmission shaft 3211 to rotate. After the transmission shaft 3211 rotates, the polishing disc 3212 will rotate, so that the surface of the jewelry can be polished by the polishing disc 3212. When the polishing position needs to be adjusted, the operator turns on the first drive motor 325 to cause the screw rod 326 to rotate. After the screw rod 326 rotates, the sleeve block 327 will move. After the sleeve block 327 moves, the lower polishing disc 3212 will move, so that the polishing position of the jewelry can be adjusted. When the surface of the jewelry needs to be polished, the operator turns on the cylinder 328 to cause the fixing seat 329 to move downward. When the fixing seat 329 moves downward, the bottom of the polishing disc 3212 will fit the surface of the jewelry. Then, the operator turns on the second drive motor 3210 to cause the transmission shaft 3211 to rotate. After the transmission shaft 3211 rotates, the polishing disc 3212 will rotate, so that the surface of the jewelry can be polished by the polishing disc 3212. When the polishing position needs to be adjusted, the operator turns on the first drive motor 325 to cause the screw rod 326 to rotate. After the screw rod 326 rotates, the sleeve block 327 will move. After the sleeve block 327 moves, the lower polishing disc 3212 will move, so that the polishing position of the jewelry can be adjusted. When the longitudinal grinding position of the jewellery needs to be adjusted, the operator turns on the electric push rod 323 to cause the movable frame 324 to move inside the fixed frame 322, thereby adjusting the longitudinal grinding position of the jewellery. During the movement of the fixed frame 322, the squeezing rod 3216 is squeezed, causing the squeezing rod 3216 to squeeze the gas inside the sleeve 3213 through the rubber block 3217, and discharge it through the exhaust pipe 3214 and the exhaust head 3215, so that the exhausted gas is convenient for blowing away the dust and debris attached to the surface of the jewellery during the grinding process, so as to prevent the dust and debris from adhering to the surface of the jewellery and affecting the grinding effect.
