Large mechanical press connecting rod semicircle machining tool

Abstract

The invention discloses a large mechanical press connecting rod semicircle machining tool which comprises a support, a cutter clamp, a semicircular plate and a cutter bar. The support is fixed to a slotting machine working table through a T-shaped bolt, the inner side of the support is connected with the cutter clamp through a dovetail groove structure, and the cutter clamp can move vertically along the dovetail groove structure; an opening is formed in the lower end of the cutter clamp, and an insertion cutter is fixed to the cutter clamp through the opening; a square opening is formed in the upper end of the cutter clamp, a semicircular plate is jointed into the square opening and is fixed to the lower end of the cutter bar through a bolt, and the cutter bar is fixed to a slotting machine sliding pillow through a clamp; the cutter bar and the semicircular plate drives the cutter clamp to do vertical motion along with the slotting machine sliding pillow; and meanwhile, the support and the cutter clamp do indexing motion along with the slotting machine working table. According to the large mechanical press connecting rod semicircle machining tool, the problem that a super-tonnage large connecting rod cannot be machined on a light slotting machine is solved, and the machining method that a connecting rod and a working table rotate around an insertion cutter in the past is changed; and meanwhile, the load of the working table is reduced, the semicircle machining accuracy is improved, and the machining scope of the light slotting machine is enlarged.

Description

technical field [0001] The invention relates to a semicircle processing tool, which belongs to the technical field of mechanical processing tool. Background technique [0002] The current semi-circle processing method of the connecting rod: fix the connecting rod on the worktable of the slotting machine, the rotation of the worktable drives the connecting rod to make a rotary motion, and at the same time, the knife rod equipped with the slotting knife makes a single up and down movement to realize the semicircle arc surface of the connecting rod. Processing; with the increasing demand for large mechanical presses, the tonnage of presses continues to increase, and the weight and shape of the connecting rods of its internal parts continue to increase. Since the weight of large connecting rods has exceeded the load-bearing range of ordinary light slotting machines, large connecting rods It cannot be processed under the existing equipment capacity, so we can only seek heavy slot...
