新聞摘要:The boring machine is easy to operate

 The portable boring machine is mainly used for processing small-scale pipe inner hole, concentric interval hole and large-scale equipment through hole on site. It is suitable for excavators, cranes, cranes and other engineering machinery, ship rudder shaft hole, stern shaft hole, pipe flange, various large-scale frame hinge holes and so on.

Performance features:


1. The rotary device of the portable boring bar has a compact structure and a high power weight ratio;
2. The boring bar is made of high-strength alloy steel, which is quenched as a whole. After stress relief and aging treatment for many times, the surface is chrome plated and polished, with high hardness, good rigidity and not easy to deform;
3. The main shaft box is driven by worm gear, which is small in volume and large in transmission ratio. The worm gear is made of imported special metal, with good lubrication, good wear resistance and long service life;
4. Various forms of support and fixing devices meet the needs of different working environments, including single arm support, one word support, T-shaped support, cross support, center support, landing support, centering support, etc;
5. Special anti vibration technology is adopted for bearing support, with high precision and rigidity;
6. The tool holder on the end face of the lathe can automatically move the tool forward and backward, the feed rate can be adjusted, and it can be disassembled, which is convenient for installation and disassembly;
7. The well-designed bearing end plate can be adjusted and tilted in any direction to compensate for any misalignment;
8. High machining accuracy, surface roughness up to Ra1.6;
9. Automatic feed of axial feed box, equipped with three speed change device, to output the most suitable feed for rough and finish machining, and equipped with forward and reverse and manual feed change gears;
The positioning device of the boring machine is characterized in that it includes a positioning seat, a positioning top core and at least three identical positioning columns, the positioning seat includes a support seat and a positioning sleeve, at least three through holes matched with the positioning column are arranged on the side wall of the positioning sleeve, each through hole is perpendicular to the center line of the positioning sleeve, the positioning top core is in the shape of nails, the fixed end is provided with a nail cap, and the working end is The cone is against the inner end of each positioning column. Compared with the prior art, the utility model has the advantages of simple structure, convenient use, accurate positioning, low cost, easy realization and greatly improved production efficiency.
