Embodiment Construction
[0011] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.
[0012] figure 1 Shown is a schematic front view of the structure of the present invention.
[0013] figure 2 Shown is a schematic cross-sectional view A-A of the present invention.
[0014] The present invention includes a bracket 5, a tool holder 13, a semicircular plate 4 and a tool bar 15.
[0015] The bracket 5 is fixed on the slotting table 14 by means of T-bolts 10 .
[0016] The inner side of the bracket 5 is provided with a dovetail groove, the rear end of the tool holder 13 is provided with an outer dovetail structure that matches the dovetail groove, and the outer dovetail structure of the tool holder 13 is placed in the dovetail groove of the bracket 5, and is passed through the screw 11 and the dovetail structure. The pressing plate 12 is closed, and the tool holder 13 moves up and down along the dovetail groove.

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 semi-circular arc processing tool, belonging to the technical field of mechanical processing tool. Background technique [0002] At present, the semi-circular arc processing method of the connecting rod is as follows: the connecting rod is fixed on the table of the slotting machine, the rotation of the table drives the connecting rod to make a rotary motion, and the tool bar equipped with the slotting knife performs a single up and down movement, so as to realize the semi-circular arc surface of the connecting rod. Processing; With the increasing demand for large mechanical presses, the tonnage of the press continues to increase, and the weight and shape of the internal parts of the connecting rod are also increasing. Because the weight of the large connecting rod has exceeded the load-bearing range of the ordinary light slotting machine table, the large connecting rod It cannot be processed under the existing equipment capac...
