Description

Technical Field

[0001] The utility model relates to the field of mechanical equipment, in particular to a device for disassembling and measuring the firmness of a watch glass. Background Art

[0002] like Figure 1 As shown, the structure of the watch can be classified into top-mounted and conventional styles according to the assembly method of the dial into the watch case 200. The shape of the watch case 200 of the top-mounted style is mostly a bowl-shaped structure with a large top and a small bottom. The disc, the hands 300, and the movement kit are restricted by the size of the bottom of the watch case 200, and can only be installed from the top of the watch case 200 and then the bezel or glass 100 is assembled. In this way, after the watch head is assembled, once the dial or the hands need to be repaired, the bezel needs to be pried open for the real bezel style, and the glass 100 needs to be disassembled for the fake bezel style. In the past, the watch glass 100 of the top-mounted fake bezel style was disassembled by using an air gun 500, and compressed dry air was introduced from the handle 600 to blow out the watch glass 100. The general steps are: pry out the bottom cover 400 → take out the crown → press the bottom cover 400 back → blow it out with the air gun 500. This method is inefficient and there is little room for improvement. In addition, similar to the fragile discs of gold sandstone and shells, the air pressure blowing process is easy to break. Removing the bezel of a genuine bezel style may easily cause the bezel to be scratched or even scrapped. Utility Model Content

[0024] The above technical solutions are basic solutions, such as Figure 2-Figure 4 As shown, the operation steps of the watch glass disassembly and fastness measurement device of the utility model include:

[0025] Step 1: According to the size of the watch glass 13, select the corresponding size of the pressing block 10 and the limiting ring 2. Then stick the double-sided tape 12 under the pressing block 10, and then operate the driving device to make the pressing block 10 and the watch glass 13 adhere. When the meter head is pressed, the force measuring display screen 6 will display the pressure value in real time (such as Figure 2The displayed pressure is 18KG); here, as long as the value is lower than the safety pressure that the watch glass 13 can withstand.

[0026] Step 2: After the watch glass 13 and the pressing block 10 are firmly glued, the driving device is operated to make the watch head rise. When the watch case part contacts the limit ring 2, the force measuring display screen 6 will display the tension value in real time (such as Figure 3 The display shows -12KG, which is the tensile force on the glass). Before the watch glass 13 is separated from the housing, the maximum value displayed is the maximum tensile force on the glass, and the tensile force represents the firmness of the watch glass 13.
