Embodiment Construction

[0013] The present invention will be described in further detail below. The method of the present invention for processing a shielded incomplete circumferential gear uses a gear shaping machine and a special gear shaping cutter, and is characterized in that the processing steps are as follows:

[0014] First, clamp the parts; fix the processed parts on the special fixture, insert the vertical positioning pin 4 on the fixture bottom plate 8 into the center hole of the incomplete circumferential gear 2 on the part, and insert the horizontal positioning pin 5 on the fixture bottom plate 8 into the part In the through hole on the last lug 3, the ring positioning surface 10 on the lower surface of the ring body 1 on the part is pushed against the end face of the end face positioning pin 6 on the side plate 9 of the fixture, and the pressure plate mechanism 7 on the bottom plate 8 of the fixture The tight end is pressed against the upper surface of the ring body 1 between the two lu...

Abstract

The invention belongs to mechanical processing technology, and relates to a method for processing a shielded incomplete circumferential gear, a special fixture and a special gear shaping cutter. The processing steps are as follows, clamping parts; installing fixtures; gear shaping. The special fixture of the present invention consists of a bottom plate (8), a side plate (9) vertically connected to the bottom plate (8), a vertical positioning pin (4), a horizontal positioning pin (5) and a pressing plate fixed on the side plate (9) Organization (7) is composed. The number of teeth of the special gear shaper cutter of the present invention is the number of teeth of the incomplete circumferential gear processed with shielding plus (2), and redundant teeth are cut off to form the incomplete circumferential gear shaper cutter. The invention solves the difficult problem of processing special parts of non-complete circumferential gears with shielding.

Description

technical field [0001] The invention belongs to mechanical processing technology, and relates to a method for processing a shielded incomplete circumferential gear, a special fixture and a special gear shaper cutter. Background technique [0002] There is a shaded non-perfect circumference gear in the helicopter part, see figure 1 stereogram of parts and figure 2 The processed part shown by the dotted line in , which consists of a ring body 1, two incomplete circumferential gears 2 with the same structure and a central hole 4, and two lugs 3 with through holes in the same structure constitute. The lower surface of the ring body 1 has a ring positioning surface 10 , one end of the ring body 1 is vertically connected with two incomplete circumferential gears 2 , and the other end of the ring body 1 is vertically connected with two lugs 3 . When the usual gear shaping method is adopted, the gear shaping cutter interferes with the ring body 1 due to the obstruction of the ri...
