Abstract
A hole boring machine for main shaft positioning pin of a water turbine belongs to hole boring equipment for pins. The hole boring machine comprises a support rod; a hand wheel is connected with a cutting feed screw rod; the cutting feed screw rod is connected with a main shaft through a nut; a connecting screw thread is formed at the lower end of the main shaft; a rotary sleeve is matched with the main shaft; the rotary sleeve is connected with a motor through a belt pulley; a sliding sleeve is arranged inside the rotary sleeve; a cutter head is arranged at the lower part of the rotary sleeve; and a cutter head is positioned on a cutter. The hole boring machine ensures that the main shaft can be adjusted and fixed on the axial line of a hole to be processed through the high-precision main shaft, as well as a rotary head, a feeding mechanism, an adjusting mechanism and the like clung to the main shaft; and the hole to be processed can be processed to meet the desired technique precision requirements according to operating procedures. The utility model has the characteristics of compact structure, reasonable layout, light weight, simple and convenient operation, strong adaptability and the like.
Description
Technical field
The utility model relates to a kind of pin Boring machine, the special-purpose boring machine of the accessory processing during a kind of especially Large Hydroelectric Set main shaft junction dowel hole is installed at the scene.
Background technology
After the integral hoisting of Large Hydroelectric Set macro-axis is in place, it is a vital ring in the whole engineering with the work of boring hinge that runner and macro-axis connecting pin oncomelania keyhole carry out the building site, the quality that reamed quality directly influences cooperating of hole and pin bolt, and the safe and stable operation of unit is in the future had a direct impact.Main shaft junction dowel hole (vertical or horizontal), specification requirements such as the precision in installing at the scene, form and position tolerance, surface roughness are very high, and place, job site narrow space, and existing bore hole facility can't use in the erecting bed.China is the erecting bed special boring machine of design at present, must wait the runner of unit to decompose with macro-axis after, macro-axis is hung out, just runner and macro-axis connecting pin oncomelania keyhole can be carried out cutting with scissors with boring, concentric with the assurance macro-axis with runner.And the Large Hydroelectric Set macro-axis weighs more than 200 tons, after integral hoisting is in place, may not hang out bore hole again, and the on-the-spot boring behind hoisted in position is hinged into and is the technical barrier in the Large Hydroelectric Set installation process.
Summary of the invention
The purpose of this utility model will provide exactly and can fully adapt to field erected specific (special) requirements, solves the hydraulic turbine main shaft alignment pin Boring machine of main shaft junction dowel hole boring hinge work in the installation process.
The purpose of this utility model is achieved in that a kind of hydraulic turbine main shaft alignment pin Boring machine, comprises strut, and handwheel is connected with the feed screw rod, and the feed screw rod is connected with main shaft by nut, and the main shaft lower end is provided with connecting thread; Rotary sleeve matches with main shaft, and rotary sleeve is connected with motor by belt pulley, is provided with sliding sleeve in the rotary sleeve, and the rotary sleeve bottom is provided with cutterhead, and cutter places on the cutterhead.
Hydraulic turbine main shaft alignment pin Boring machine provided by the utility model, by the high accuracy main shaft and depend on rotary head on the main shaft, feed mechanism, guiding mechanism etc., the main shaft adjustment is fixed on the axis of institute's machining hole, according to operating procedure, just processed hole can be worked into desired technology acuracy by the processing personnel.This device have compact conformation, rationally distributed, weight is light and handy, easy and simple to handle, characteristics such as adaptability is strong.
Description of drawings
Below in conjunction with drawings and Examples the utility model is done a step explanation.
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The utility model adopts following structure: a kind of hydraulic turbine main shaft alignment pin Boring machine, comprise strut 1, and handwheel 2 is connected with feed screw rod 3, and feed screw rod 3 is connected with main shaft 5 by nut 4, and main shaft 5 lower ends are provided with connecting thread 11; Rotary sleeve 6 matches with main shaft 5, and rotary sleeve 6 is connected with motor 8 by belt pulley 7, is provided with sliding sleeve 10 in the rotary sleeve 6, and rotary sleeve 6 bottoms are provided with cutterhead 9, and cutter places on the cutterhead 9.
Operation principle of the present utility model is: main shaft 5 is stood on center, processed hole and proofreaies and correct perpendicularity, rotate handwheel 2, by hand cutter screw rod 3 cutter that is positioned at cutterhead 9 is contacted with machined surface, start motor 8, drive main shaft 5 by belt pulley 7 and rotary sleeve 6 and rotate, make cutter finish the operation of pin bore hole.
The effect of sliding sleeve 10 is to guarantee that rotary sleeve 6 can accurate move axially up and down, the cylindricity of control machining hole.
Connecting thread 11 is connected with existing screw on the processed hydraulic turbine main shaft.Be that the utility model is with connection between the processed hole and basis, location.
