With the flat face of milling one end；Flat-nose pliers is unclamped during dismounting part, part and clamp body are taken out simultaneously, in milling another side,
Part conversion is installed, then just can be with the other flat face of milling after being clamped with flat-nose pliers.Two ends are completed with same above-mentioned handling mode
The flat technique of milling.
Further, the clamping Kong Weiyi, the location hole is two, is symmetrically placed in clamping hole both sides；Or it is described
Clamping hole is two, and the location hole is two, and on the left of the first clamping hole, the second location hole is located at second to the first location hole
On the right side of clamping hole, so can simultaneously complete two stuffing-boxes first of milling it is flat, then change position, while two stuffing-boxes second of milling
It is flat, improve working (machining) efficiency.
Further, the alignment pin includes alignment pin prismatic portion and alignment pin cylindrical portion, and the alignment pin prismatic portion wears
Cross location hole and stuffing-box bolt hole is positioned to stuffing-box, there are arc side, the arc side and filler in the alignment pin prism portion
Letter bolt hole internal diameter is tangent, the alignment pin that this spline structure makes through with pass conveniently, and positioning precision effect also can guarantee that, improve
The efficiency clamp, dismantled.
Relative to prior art, the flat clamping tooling of stuffing-box milling described in the utility model and clamp method have following excellent
Gesture：
Jig Design described in the utility model is simple, and reasonable positioning is economic and practical, and technical requirements can be guaranteed.
