In the prior art, the manual device of the boring bar bracket of the drawing and boring machine is mainly composed of a manual device base, fastening bolts, positioning pins, circlips, rotating shafts, bushings, racks, flat keys, transmission gears, circlips for shafts, etc. , but there are three inconvenient factors: 1. The inner tapered sleeve (nylon) sometimes produces a lot of friction with the boring bar due to wear and squeeze; 2. The weight of the boring bar bracket itself; 3. The gear The moving force generated between the rack and the rack is biased on the side of the boring bar support, and the distance from the center is relatively large
These three factors make the operator's work heavy and inconvenient when adjusting the position of the boring bar holder
In addition, because the inner tapered sleeve (nylon) is squeezed tightly, the boring bar is squeezed to death, and is often passively dragged and moved by the boring bar, and the meshing position between the gear and the rack is offset to the side of the boring bar bracket. And the distance from the center is relatively large, so from time to time there will be a vicious equipment event that the gear and the rack are locked first, and then the boring head and the boring bar are pulled off

The invention discloses a boring machine boring bar support hand-operated device comprising a hand-operated device pedestal, a fastening bolt I, a positioning pin, a fastening screw, an end cover plate, a bull gear, a shaft sleeve I, a fastening bolt II, a shaft sleeve II, a rotary flat key I, a rotary shaft I, a rotary shaft cover plate, a shaft sleeve III, a pinion, a shaft sleeve IV, a gear rack, a rotary flat key II, a spline rotary shaft II, a transfer gear and a shaft stop ring; the hand-operated device and the boring bar support pedestal are connected not only by the positioning pin and screw, and embedded into a pedestal groove, so connection is more flexible; the bull gear-pinion engagement structure is added to save laboring; the spline release structure between the gear wheel and gear rack is added, thus preventing major equipment damage accident from happening.
Description
technical field [0001] The invention belongs to a bracket manual device, in particular to a manual device for a boring bar bracket of a boring machine. Background technique [0002] During the working process of the boring machine, in order to meet the need of guiding the boring bar, the position of the boring bar support needs to be constantly changed, which requires a manual device to complete. In the prior art, the manual device of the boring bar bracket of the drawing and boring machine is mainly composed of a manual device base, fastening bolts, positioning pins, circlips, rotating shafts, bushings, racks, flat keys, transmission gears, circlips for shafts, etc. , but there are three inconvenient factors: 1. The inner tapered sleeve (nylon) sometimes produces a lot of friction with the boring bar due to wear and squeeze; 2. The weight of the boring bar bracket itself; 3. The gear The moving force generated between the rack and the rack is offset to the side of the bo...
