Technical field
The present invention relates to a kind of drill, the hand-held power commutation drill of high-speed gear box special use specifically, belongs to high-speed gear box technical field of processing equipment.
Background technology
During the operation of single-stage high-speed centrifugal blower, need lubricating oil lubricated and cooling to high slow-speed shaft, so designed the oil circuit to the technical stipulation parameter of this equipment between two axis holes.But less because of the aperture of axis hole, and oil circuit hole and axis hole be 90 ° of angles, so adopt existing general rig cannot complete the processing to oilhole between high-speed gear box axis hole.
Summary of the invention
The object of the invention is to overcome above-mentioned weak point, thereby the special-purpose hand-held power commutation of a kind of high-speed gear box drill is provided, can complete the processing of oilhole between high-speed gear box axis hole, and can guarantee machining accuracy.
According to technical scheme provided by the invention, the special-purpose hand-held power commutation of high-speed gear box drill comprises fixed head, it is characterized in that: from left to right stiff end lid top panel, front-end bearing pedestal and rear bearing block successively on fixed head, in front-end bearing pedestal and rear bearing block by bearings power transmission shaft; Described power transmission shaft one end connects portable drill gun by adapter sleeve, and the other end connects the first bevel gear; End cap top board is provided with self-lubricating bearing, is provided with the second bevel gear with the first bevel gear Vertical Meshing under self-lubricating bearing, and the second bevel gear is installed bearing by bevel gear and is arranged on fixed head; Described the second bevel gear center is provided with drill bit locking member, and drill bit is installed in drill bit locking member, between drill bit locking member and self-lubricating bearing, is provided with thrust bearing, and thrust bearing compresses drill bit locking member and the second bevel gear.
Further, drill bit is by the screw lock on drill bit locking member.
Further, power transmission shaft outer ring is provided with guard shield that power transmission shaft cover is got up.
Compared with the prior art the present invention has the following advantages:
The present invention is simple in structure, compact, reasonable, and cost is lower, easy to operate, and continuity is good, and the scope of application is extensive; Can in two axis holes of high-speed gear box, by direction-variable power, realize the break-in of oilhole and cut, can not destroy the wall thickness of casing, guarantee that non-machining area is not impaired; Thrust bearing compresses drill bit locking member and the second bevel gear, prevents that drill bit locking member from moving axially, and has guaranteed stability and the precision of boring.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is that the present invention uses schematic diagram.
Description of reference numerals: 1-fixed head, 2-end cap top board, 3-self-lubricating bearing, 4-drill bit locking member, 5-thrust bearing, 6-bevel gear are installed bearing, 7-drill bit, 8-the second bevel gear, 9-the first bevel gear, 10-front-end bearing pedestal, 11-power transmission shaft, 12-guard shield, 13-rear bearing block, the portable drill gun of 14-, 15-adapter sleeve, 16-gear housing, 17-axis hole, 18-oilhole.
The specific embodiment
The present invention is below further described in connection with the embodiment in accompanying drawing:
As shown in Figure 1, the present invention mainly comprises fixed head 1, from left to right stiff end lid top panel 2, front-end bearing pedestal 10 and rear bearing block 13 successively on fixed head 1, in front-end bearing pedestal 10 and rear bearing block 13 by bearings power transmission shaft 11.Described power transmission shaft 11 one end connect portable drill gun 14 by adapter sleeve 15, and the other end connects the first bevel gear 9.Portable drill gun 14 provides the power of power transmission shaft 11 rotations, drives the first bevel gear 9 on power transmission shaft 11 to rotate.
End cap top board 2 is provided with self-lubricating bearing 3, is provided with by bevel gear, bearing 6 to be installed with the second bevel gear 8, the second bevel gears 8 of the first bevel gear 9 Vertical Meshing and to be arranged on fixed head 1 under self-lubricating bearing 3.
Described the second bevel gear 8 centers are provided with drill bit locking member 4, the interior installation drill bit 7 of drill bit locking member 4, and drill bit 7 is by the screw lock on drill bit locking member 4.Portable drill gun 14 drives the first umbrella shape tooth 9 to take turns while rotating, and drives with the second bevel gear 8 of the first bevel gear 9 engagements and rotates, and the second bevel gear 8 drives again the drill bit 7 being locked in the second bevel gear 8 to rotate, and realizes the boring of oilhole between two axis holes.
Between described drill bit locking member 4 and self-lubricating bearing 3, be provided with thrust bearing 5, thrust bearing 5 compresses drill bit locking member 4 and the second bevel gear 8., during boring, drill bit locking member 4 can be subject to the power making progress, and drill bit locking member 4 is moved axially, so thrust bearing is set between end cap top board 2 and drill bit locking member 4, prevents to move axially.
Described power transmission shaft 11 outer rings are provided with covers by power transmission shaft 11 the guard shield 12 of getting up, and guard shield 12 protection power transmission shafts 11, prevent that power transmission shaft 11 is damaged.
Operation principle of the present invention is: as shown in Figure 2, when boring oilhole, fixed head is stretched in axis hole, drill bit is aimed at machining of oil hole position.Open the umbrella shape tooth of portable drill gun by a pair of Vertical Meshing 90 ° of power are turned to, realize the processing of drill bit to oilhole.Because axis hole aperture is little, portable drill gun is inconvenient to enter boring, and therefore on fixed head, the umbrella shape tooth by a pair of Vertical Meshing turns to 90 ° of power, realizes the break-in of oilhole cut by direction-variable power, can not destroy the wall thickness of casing, guarantee that non-machining area is not impaired.Thrust bearing compresses drill bit locking member and the second bevel gear, prevents that drill bit locking member from moving axially, and has guaranteed stability and the precision of boring.Cost of the present invention is lower, easy to operate, and continuity is good, and the scope of application is extensive.
