Abstract
The invention discloses an eccentric upper valve deck drilling clamp and a clamping method of the eccentric upper valve deck drilling clamp. The eccentric upper valve deck drilling clamp comprises a cushion block, a bolt, adjusting bolts, movable clamps, a fixed clamp, screw rods, adjusting nuts, a pressing block, a supporting base, a base and threaded holes. The clamp is suitable for being used for drilling holes in an eccentric upper valve deck. The eccentric upper valve deck is clamped on the clamp, and the eccentric upper valve deck can be drilled simultaneously in the front and the back. The eccentric upper valve deck drilling clamp is simple in using method and low in requirements for technical level of workers; the eccentric upper valve deck can be drilled with only one time of clamping, and thus the production efficiency is high. The eccentric upper valve deck drilling clamp is easy to machine, low in cost and suitable for drilling eccentric upper valve deck with different sizes.
