In the structure, the upper end surface of the fixture body is provided with a plurality of positioning grooves which are longitudinally, oppositely, parallelly and equidistantly arranged; and the positioning block at the lower part of the positioning seat is embedded into the positioning groove and is in clearance fit with the positioning groove.

In the above configuration, the platen width H is less than the distance L between two workpieces below the platen.

Compared with the prior art, the utility model, following positive effect has:

1. the lower part of the positioning seat is provided with a rectangular positioning block; the positioning block at the lower part of the positioning seat is embedded into the T-shaped groove on the upper end face of the fixture body and is in clearance fit with the T-shaped groove, so that different positioning seats can be installed on the same fixture body as long as the positioning block at the lower part of the positioning seat is the same, and the positions of the positioning seat and the clamping mechanism can be transversely adjusted along the T-shaped groove as required, so that the requirements of various valve plates on processing on a processing center are met, the fixture body does not need to be replaced, the longitudinal position of the positioning seat does not need to.

2. The upper end surface of the fixture body is provided with a plurality of positioning grooves which are longitudinally, relatively, parallelly and equidistantly arranged; the positioning block at the lower part of the positioning seat is embedded into the positioning groove and is in clearance fit with the positioning groove, so that different valve plates are processed, the positioning seats corresponding to the valve plates are positioned in the positioning groove in sequence according to needs, and the positioning grooves are equidistant, so that the transverse positions of the positioning seats are not required to be corrected when the valve plates are processed in a processing center, and the production efficiency is further improved.

3. The width H of the pressing plate is smaller than the distance L between two workpieces below the pressing plate, and after the workpieces are machined, the pressing plate can be rotated by 90 degrees without being detached, the workpieces can be detached and installed again, and the production efficiency is further improved.
