Description

Technical Field

[0001] The utility model relates to the technical field of watch processing, in particular to a fixture for polishing a watch dial panel. Background Art

[0002] A watch is a portable timepiece that is carried or worn by people. It is also called a wristwatch. Watches can be divided into mechanical watches, electronic watches, etc. Among them, mechanical watches are the most representative. Mechanical watches are timing instruments with mechanical vibration systems. Their working principle is to utilize a vibration system with a constant period and continuous vibration. They are generally composed of several parts such as energy, wheel train, escapement, vibration system, pointer mechanism and additional mechanism.

[0003] Mechanical watches, especially expensive mechanical watches, need to be polished and ground, especially the watch dial panels, which require precision grinding. During the polishing and grinding process, the watch dial panels need to be clamped and fixed. For example, a fixing device and watch grinding equipment with application number 201922500307.9 can clamp and fix the watch dial panels, and can adjust them at a certain angle, making the polishing process simpler, reducing the labor intensity of workers and improving grinding efficiency; however, this solution still adopts the clamping and fixing method. For expensive watches, this fixing method may leave processing marks, making the watch less beautiful as a whole. At the same time, when polishing precious metal watches, the precious metal powder polished off is not recycled, which increases the cost of polishing and grinding to a certain extent.

Since the clamping force is performed by atmospheric compression, it is a non-contact clamping force, and therefore will not cause damage to the outside of the watch dial panel.

[0024] Specifically, the recycling structure includes: a recycling rack 9, a recycling hopper 10, three recycling air pipes 11 and a recycling filter 12; the recycling rack 9 is installed on the side wall of the supporting bracket 2, the recycling hopper 10 is installed on the upper wall of the recycling rack 9, one end of the three recycling air pipes 11 is respectively installed inside the recycling hopper 10, and the recycling filter 12 is installed at the other end of the three recycling air pipes 11.

[0025] Working principle: When using the utility model, first connect the external AC power supply to the utility model to provide energy for the electrical appliances in the utility model. The operator first directly snaps the watch dial panel onto the upper wall of the dial mold 1. At this time, the adsorption air pump 7 is started. At this time, the air inside the four adsorption tubes 4, the four adsorption hoses 5 and the adsorption main pipe 6 is discharged by the adsorption air pump 7. At this time, the watch dial panel is in contact with the four adsorption tubes 4, and a good sealing effect can be achieved through the four sealing disks 15. At this time, the four adsorption tubes 4, the four adsorption hoses 5 and the adsorption main pipe 6 are in a negative pressure. Under the action of atmospheric pressure, the watch dial panel is tightly adsorbed on the dial mold 1, and then the operator can polish the watch dial panel. At this time, metal debris will fly out from between the polishing tool and the watch dial panel. If it is a watch dial panel made of precious metal, such fine metal debris will float away. At the same time, the operator starts the recovery air pump 13, and the gas above the dial mold 1 will pass through the recovery hopper 10, three recovery air pipes 11 and the recovery filter 12. At this time, the fine precious metal debris will be intercepted by the recovery filter 12, thereby ensuring the loss of precious metals.
