The purpose of this utility model is to overcome above-mentioned weak point, thereby the special hand-held power commutation of a kind of high-speed gear box drill is provided, and can complete the processing of oilhole between high-speed gear box axis hole, and can ensure machining accuracy.
The technical scheme providing according to the utility model, the special 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 and the second bevel gear of 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 the guard shield that power transmission shaft cover is got up.
Compared with the prior art the utility model has the following advantages:
The utility model 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 of a high-speed gear box axis hole, realize the break-in cutting of oilhole by direction-variable power, can not destroy the wall thickness of casing, ensure 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 ensured stability and the precision of boring.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is that the utility model 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.
Detailed description of the invention
The utility model is further described in connection with the embodiment in accompanying drawing below:
As shown in Figure 1, the utility model 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.The power that portable drill gun 14 provides power transmission shaft 11 to rotate, 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 rotation, drives the second bevel gear 8 engaging with the first bevel gear 9 to rotate, 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., when boring, drill bit locking member 4 can be subject to a power upwards, and drill bit locking member 4 is moved axially, and prevents to move axially so thrust bearing is set between end cap top board 2 and drill bit locking member 4.
Described power transmission shaft 11 outer rings are provided with the guard shield 12 that power transmission shaft 11 covers are got up, and guard shield 12 is protected power transmission shaft 11, prevents that power transmission shaft 11 is damaged.
Operation principle of the present utility model is: as shown in Figure 2, in the time boring oilhole, fixed head is stretched in axis hole, drill bit is aimed at machining of oil hole position.Open portable drill gun and by the umbrella shape tooth of 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 cutting of oilhole by direction-variable power, can not destroy the wall thickness of casing, ensure 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 ensured stability and the precision of boring.The utility model cost is lower, easy to operate, and continuity is good, and the scope of application is extensive.
