Abstract
The utility model discloses a quartering drilling device for a generator shaft. The quartering drilling device comprises a base plate; a fixing plate is vertically fixed on the base plate; a drilling template is fixed at the upper end of the fixing plate; a positioning mandrel passes through the fixing plate; one end surface of the fixing plate is rotatably connected with a rotating disc, through which the position mandrel passes; four positioning holes are uniformly formed in one end surface of the fixing plate, relative to the rotating disc; rotating positioning pins for locking the positioning holes are correspondingly arranged on the fixing plate; compression springs are arranged in inner chambers of the rotating positioning pins; the generator shaft is sleeved on the positioning mandrel; one end of the generator shaft presses against the rotating disc; and a positioning pressure plate which is sleeved on the positioning mandrel is fixed at the other end of the generator shaft. With the adoption of the quartering drilling device for the generator shaft, by using the fixing of the positioning holes and the rotating positioning pins of the rotating disc, the generator shaft can be conveniently rotated for 90 degrees, so that quartering drilling to the generator shaft can be accurately performed; the quartering drilling is simple to operate; the time and the labor are saved; the processing efficiency is high; and meanwhile the quartering drilling device is low in cost.
Description
Technical field
The utility model relates to the process equipment of generator shaft, relates in particular to the quartering drilling equipment of generator shaft.
Background technology
The branch borehole that waits of traditional generator shaft generally adopts Ni Zhifu drill (multi spindle drilling machine) or cover die to realize.When with Ni Zhifu drill generator shaft being waited branch borehole, a plurality of drill bits in the equipment need balanced fixing, and therefore debugging drill bit need take much time, and operating personnel are required height, and product rejection rate is high; And when adopting cover die that generator shaft is waited branch borehole, need supporting special mould, thereby increased processing cost, and cover die processing slowly, efficient is low.
Summary of the invention
The purpose of the utility model provides a kind of quartering drilling equipment of generator shaft of can be fast generator shaft being holed.
Be the realization above-mentioned purpose, the quartering drilling equipment of the utility model generator shaft, it comprises base plate; Vertical fixing has fixed head on the base plate, and the fixed head upper end is fixed with bushing plate, is equipped with positioning core axle on the fixed head; Fixed head one end face is rotatably connected to the rotating disc that wears positioning core axle; Evenly be provided with four locating holes on one end face of rotating disc relative fixed plate, the corresponding positioning of rotating pin that is provided with the holding locating hole is provided with the compression spring on the fixed head in the inner chamber of positioning of rotating pin; Generator shaft is set on the positioning core axle, and the boring in the bushing plate is aimed at generator shaft and needed bore position, and generator shaft one end is butted on rotating disc, and the other end is fixed with the positioning pressuring plate that is set on the positioning core axle.
Said positioning core axle is connected with handle at fixed head away from an end of rotating disc.
Adopt the structure of the utility model, utilize the locating hole of rotating disc and fixing of positioning of rotating pin, can easily generator shaft be rotated 90 °; And then accurately generator shaft is carried out quartering boring, and adopting No. one time clamping, a mold can be realized the quartering boring to generator shaft; This quartering drilling operation is simple; Time saving and energy saving, working (machining) efficiency is high, and the quartering drilling equipment cost of the utility model is low simultaneously.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation:
Fig. 1 is the cutaway view of the quartering drilling equipment of the utility model generator shaft;
Fig. 2 is the partial sectional view of the quartering drilling equipment of the utility model generator shaft.
The specific embodiment
Like Fig. 1 or shown in Figure 2; The quartering drilling equipment of the utility model generator shaft, it comprises base plate 1, vertical fixing has fixed head 2 on the base plate 1; Fixed head 2 upper ends are fixed with bushing plate 3; Be equipped with positioning core axle 4 on the fixed head 2, fixed head 2 one end faces are rotatably connected to the rotating disc 5 that wears positioning core axle 4, evenly are provided with four locating holes 6 on the end face of rotating disc 5 relative fixed plates 2; The corresponding positioning of rotating pin 7 that is provided with holding locating hole 6 on the fixed head 2 is provided with compression spring 8 in the inner chamber of positioning of rotating pin 7; Generator shaft 9 is set on the positioning core axle 4, and the boring 31 in the bushing plate 3 is aimed at generator shaft 9 and needed bore position, and generator shaft 9 one ends are butted on rotating disc 5, and the other end is fixed with the positioning pressuring plate 10 that is set on the positioning core axle 4.
Adopt above structure, generator shaft 9 is set on the positioning core axle 4, the one of which end is butted on rotating disc 5; The other end is fixing with the positioning pressuring plate that wears positioning core axle 4 10, and the position that generator shaft 9 needs boring is aimed in the boring 31 in the bushing plate 3, adopts milling head that generator shaft 9 is holed then; Completion of processing is unclamped the nut of stationary positioned mandrel 4 and positioning pressuring plate 10, and the compression spring 8 in the positioning of rotating pin 7 ejects positioning of rotating pins 7 with rotating disc 5; Then rotating disc 5, positioning pressuring plate 10 and generator shaft 9 are rotated 90 ° synchronously around positioning core axle 4, when rotateing in place, positioning of rotating pin 7 snaps in another the locating hole 6 in the rotating disc 5; Locking positioning of rotating pin 7, at this moment, generator shaft 9 another positions that need hole are aimed in the boring 31 in the bushing plate 3; The nut of locking positioning mandrel 4 and positioning pressuring plate 10 again; Adopt milling head to be holed in generator shaft 9 another positions, repeat above operation, accomplish quartering boring generator shaft 9.
Said positioning core axle 4 is connected with handle 11 at fixed head 2 away from an end of rotating disc 5, is convenient to rotational positioning mandrel 4.
