(1) drilling range: ф 31 mm;
(2) trip: 40 mm
(3) power 1.2 horsepower (1.6 KW) import GX35 Honda petrol engine
(4) 10 s unloading is 10 s card time machine time
5. The whole machine 19 kg weight ACTS accordingly
6. Suitable for drilling 50 to 60 kg/mg type rail. Specific rail waist position (replacement card block).
All landowners pitch deviation within + / - 0.25 mm.
End up drilling time 45 s. it has work stability, easy maintainability, and safety and serviceability. Its social benefit is big, can improve the mechanization degree of drilling operation, ensure the quality, improve efficiency, to repair the shorten time of operation, at the same time reduce the physical labor of workers
Two product design and design scheme selection was based on delicate appearance, small volume, light weight, handling, simple structure, easy to workers. Imported Honda 1.6 KW gasoline engine as power source, reducer casing used aluminium alloy, transmission adopts gear drive. Alloy steel hollow drill bit adopted. The design process is:
1, the thorough market investigation and study, relying on years of production experience, understanding of users and the requirements of labor workers
NZG - 32 drilling machine 2. Analysis of the advantages and disadvantages, as well as on the structure can be inherited.
3. The scheme comparison and determine the best solution
The gear transmission is used in the main movement of bit rotation;
(2) feed movement using sleeve type rack drive;
(3) the main motion and feed movement is matched with the spindle cohesion;
(4) the machine on the rail card with bolt locking mechanism.
