Described lever arm comprises brace through bending, be used for the nut that is socketed in the U-shaped sheet on guide rod and is complementary with screw mandrel, the two ends of brace respectively with the two ends riveted joint of U-shaped sheet, the bending part parcel nut of brace, and pass through tightening of rivet; Wire rod thread is connected in the screw of nut;
Described fixed arm comprises two symmetrical support arms, their end respectively after bending, the closed guide rod hole that forms, pegging graft in guide rod hole in the top of guide rod, and passes through tightening of rivet; Be fixedly connected with by rivet between two support arms.
Another object of the present invention is to provide a kind of manufacturing process of above-mentioned F type carpenters' clamp, it is characterized in that: comprise the steps:
Fixed arm is made in A, selection:
A1, be made into two support arms with two carbon steel sheet by Sheet Metal Forming Technology;
A2, an end of two support arms is carried out bending and molding respectively and process;
A3, with two support arms and together, and by tightening of rivet, they form the guide rod hole that is complementary with guide rod after the closed end that bending is processed;
B, selection creative activity arm:
B1, make U-shaped and a brace that is used for being socketed on guide rod with carbon steel sheet by Sheet Metal Forming Technology respectively;
B2, brace is folded in half into type from the centre, then, its two ends is riveted with the two ends of U-shaped respectively; The bending part of brace arranges a nut that is complementary with screw mandrel, and uses tightening of rivet;
C, assembling:
In C1, the top insertion guide rod hole with guide rod, and use tightening of rivet;
C2, lever arm is enclosed within on guide rod by the U-shaped sheet;
C3, wire rod thread is connected in the screw of nut.
Owing to having adopted technique scheme, compared with prior art, the F type carpenters' clamp overall weight that adopts manufacturing process of the present invention to make is light, thereby uses very lightly, and durable tolerance is higher; There is no the generation of pernicious gas and residue in production process, environment friendly and pollution-free, and also production efficiency is high.
The present invention will be further described below in conjunction with the drawings and specific embodiments.
