Description

Technical Field

[0001] The utility model relates to the technical field of metal porcelain product grinding, in particular to a metal porcelain product grinding device with a replaceable grinding head. Background Art

[0002] Porcelain fused to metal is a dental restoration technology that combines metal and ceramic materials to make crowns or bridges for repairing damaged or missing teeth. The porcelain fused to metal polishing device is used to polish the crowns or bridges made of porcelain fused to metal to ensure the aesthetics of the crowns or bridges made of porcelain fused to metal.

[0003] When grinding crowns or bridges, the existing metal porcelain product grinding device generally requires an operator to hold the crown or bridge while grinding. If the operator's hand slips during the grinding process, the metal porcelain product grinding device may scratch the operator's hand, posing a safety hazard. At the same time, the grinding head of the existing metal porcelain product grinding device must be manually loosened, replaced and tightened by the operator during the replacement process. The tightening process is very laborious and inconvenient for the operator to quickly replace it. Utility Model Content

[0012] The beneficial effects of the utility model are as follows:

[0013] 1. The utility model places the crown or bridge between two clamping blocks, rotates the screw rod, and drives the clamping blocks to fix it. Then the operator takes out the grinder body from the inside of the L-shaped placement hole plate, and uses the grinder body to make the grinding head grind the crown or bridge. When the operator needs to replace the grinding head, the operator pushes the adjustment block upward, and the adjustment block drives the limit bevel block to move upward to squeeze the second spring, causing the second spring to undergo elastic deformation. At the same time, the limit bevel block moving upward releases the limit on the fixed block, so that the first spring pushes the annular hole plate to move under its elastic potential energy, and the moving annular hole plate drives The fixing block is away from the inside of the positioning hole, so that it is convenient for the operator to replace the new grinding head. After the grinding head is replaced, the operator loosens the adjusting block, so that the second spring pushes the limiting bevel block downward under its elastic potential energy, and the downward moving limiting bevel block pushes the fixing block to re-enter the inside of the positioning hole to fix the grinding head. This device can fix the crown or bridge that needs to be polished, and the operator does not need to hold the crown or bridge to polish, which prevents the operator from grinding and injuring his hands, avoiding safety hazards. At the same time, it is convenient for the operator to quickly replace the grinding head, avoiding the operator from manually loosening, replacing and tightening it, and reducing the operator's workload.

[0014] 2. The utility model utilizes the setting of the brush, which can facilitate the operator to clean the debris remaining on the surface of the grinding table of the device after use, thereby preventing the remaining debris from accumulating on the surface of the grinding table and affecting the aesthetics of the device.

[0015] 3. The utility model utilizes the setting of the charging hole, which can facilitate the operator to charge the battery through the charging hole, so that the battery can provide a stable power supply to the grinder body, thereby ensuring the normal use of the device.
