Detailed Description

The utility model is further described below with reference to examples and figures:

when the ceramic key caps 18 are shaped, the ceramic key caps 18 are placed in a clamping device, a grinding wheel in a grinding device is started to grind the surface of one ceramic key cap 18, and cold water in a water pipe is used for flushing the grinding place of the ceramic key caps 18 to dissipate heat during grinding.

Example 1

As shown in fig. 1, 2 and 3, the clamping device comprises a clamp and a pressing mechanism, wherein the jacket comprises a cover plate 111, a main body 112 and a limiting plate 113; the pressing mechanism comprises a hand-screwed bolt, a pressing block 15, an adjusting block 16, a cushion block 12 and a base plate 17. The cover plate 111, the main body 112 and the limiting plate 113 are all cuboid, the limiting plate 113 is fixedly connected to the lower end of the main body 112, the cover plate 111 is movably covered on the upper end of the main body 112, and the front ends of the limiting plate 113 and the cover plate 111 extend out of the main body 112. The cover plate 111, the main body 112 and the limiting plate 113 form a strip-shaped groove, and a plurality of ceramic key caps 18 are connected end to end and clamped in the strip-shaped groove side by side.

A movable jacket and a spacer 12 are placed on the base plate 17, and the jacket is placed at the front end of the base plate 17, and the spacer 12 is placed at the rear of the jacket. The adjusting block 16 is placed between the spacer block 12 and the pressing block 15, and the pressing block 15 is placed above the adjusting block 16 and the cover plate 111. In this embodiment, the cushion block 12 is a whole strip-shaped metal block, and two pressing blocks 15 and two adjusting blocks 16 are respectively disposed at two ends of the cushion block 12.
