Abstract
The utility model provides a deflection drill for steam turbine rotor blade wheel pin hole processing. The utility model is composed of a machine tool body, a guiding track, a transmission case, a drill arm, etc. Three shafts are arranged in a box body of an upper saddle. Gears which can be mutually engaged are arranged on the shafts, wherein, a chain wheel is arranged on one shaft. The chain wheel is driven by a chain wheel on a main shaft through a chain. Thus, the main shaft is rotated for realizing a drilling function. The drill arm is leaned against a drill arm support through pin shaft positioning and screw fastening. The longitudinal automatic and manual feed of the main shaft can be realized by the means that a gear box is driven by a screw rod and a nut. The transversal manual feed of the main shaft can be realized by the means that the gear box is driven by the screw rod and the nut. Due to the structure, the center of a main shaft of a machine tool of the utility model is not required to be aligned to absolute consistence with a rotor center height. Thereby, the utility model has the advantages of alignment difficulty reduction and processing efficiency enhancement. The drill arm can be optionally lifted for rapidly replacing cutters. After the deflection drill of chain transmission is used, production efficiency can be enhanced five times or so.
Description
Technical field
The utility model belongs to turbine rotor impeller pin hole special processing equipment.
Background technology
Known to the research of applicant's professional production: because it is minimum to open grade size between the turbine rotor impeller, each steam turbine professional production producer is general to adopt fixing gear drive machine tool structure to hole.Its shortcoming is tool changing inconvenience, inefficiency, inconvenient operation.
Summary of the invention
Task of the present utility model is intended to improve the working (machining) efficiency of turbine rotor impeller pin hole, the tool changing scheme has been carried out on the basis of feasibility analysis, design, produce and a kind ofly drive main axis rotation, realize drilling function, and can realize that drill boom laterally, longitudinally manually and the Deflection drill of power feed with chain transmission mode.
Task of the present utility model is to adopt following structure to realize: this Deflection drill comprises lathe bed, guide rail, transmission case, several most of compositions of drill boom, it is characterized in that: three axles are arranged in the transmission case body, the energy pitch wheel is housed on the axle, wherein gear and sprocket wheel are housed on one, sprocket wheel on this can make another sprocket wheel rotation by chain in drill boom.
Drill boom leans against on the drill boom backer, and the drill boom backer is fastened on the transmission case body by screw, and locking device is installed on the drill boom, and lifting handle is arranged on the drill boom, and the screw of adjusting the drill boom height is housed on the transmission case body, and transmission case body has shifting apparatus outward.
Transmission case body is pressed on the middle carriage, middle carriage equally also is pressed on the saddle, and the screw pair that transmission case is vertically moved and laterally move is arranged between them.
Saddle is connected with the machine power slide unit by T type bolt.
Drill boom main shaft endoporus is equipped with collet, adopts the collet clamp-on tool.
The utility model makes it have following beneficial effect owing to adopt the said structure technical measures: can realize drill boom laterally, hand feed longitudinally and power feed; Can determine the relative position of main shaft on the drill boom according to the position relation of drill boom and turbine rotor impeller pin hole, because adopting chain transmission, drill boom can arbitrarily raise, lower, therefore, it is definitely consistent with the rotor center height that the machine tool chief axis center can require centering to arrive, thereby reduced the centering difficulty of lathe, improved working (machining) efficiency; Can arbitrarily drill boom be mentioned and carry out knife quick change; Use chaindriven Deflection drill, can enhance productivity about five times.

The specific embodiment
With reference to Fig. 1, Fig. 2, Fig. 3, Deflection drill comprises several most of compositions such as lathe bed, guide rail, transmission case 10, drill boom 1.The horizontal level height of lathe is to be achieved by the height dimension of adjusting the fot screw under the lathe bed.In the transmission case body (going up planker) 10 three axles (6,8,9) are arranged, the energy pitch wheel is housed on the axle 8,9, axle is equipped with gear (can with the gears engaged on the axle 7) and sprocket wheel 11 on 6, the sprocket wheel of axle 6 is in drill boom 1, in the drill boom 1 main shaft endoporus collet 3 is housed, with its clamping cutter 4, link to each other with sprocket wheel 2 and drive its rotation by chain 11; Drill boom 1 leans against on the drill boom backer 12, and drill boom backer 12 is fastened on the transmission case body 10 by screw; Locking device (7,13) is installed on the drill boom; The screw 5 of adjusting the drill boom height is housed on the transmission case body; Transmission case body has shifting apparatus 15 outward; Transmission case body (go up planker) 10 by the dovetail guide pair be pressed on the middle carriage 24, middle carriage 24 equally also is pressed on the saddle 17, and screw pair 23 and corresponding hand feed handle 22 and 20 that the transmission case vertical and horizontal are moved are arranged between them; Saddle 17 is connected with the machine power slide unit by T type bolt 21.Adopt collet 3 clamp-on tools; Lifting handle 14 is arranged on the drill boom.Gear 18 rotations on 19 in the motor are after after reduction gearing 16 slows down, drive axle 9 and rotate, the gears engaged of the gear on the axle 9 and axle 8, with the gears engaged of axle 6,, pass on the sprocket wheel 2 again by chain 11, drive cutter 4 rotations on the collet 3, carry out drilling processing.
Operating procedure:
A) roughly adjust the relative position height of machine tool chief axis and rotor center according to the level height of rotor, owing to adopt chain drive structure, the mechanism that the fine setting at center can be adjusted on the drill boom determines consistent with the center, hole.
B) the centering plug is inserted in the lathe drill boom main shaft, after the adjustment lathe makes the centering plug and the impeller of rotor end face is vertical, clamp drill boom.
C) determine main shaft and pin-and-hole lateral attitude by impeller pin hole position scribing position.
D) after main spindle's is determined, load onto cutter and can carry out length feed drilling (manual or motor-driven).
