Detailed Description
In order to make the technical means, the creation characteristics, the achievement purposes and the functions of the invention easy to understand, the invention is further explained by combining the specific embodiments.
As shown in fig. 1 to 4, a perforating device of aerogenerator cabin cover, including electric drill 1, still include cylinder drill bit 4, fixedly connected with connecting piece 3 on electric drill 1's the rotatory output shaft 2, the surface of the 3 latter half of connecting piece is equipped with the screw thread, and the bottom of connecting piece 3 still is equipped with a plurality of draw-in grooves 30, cylinder drill bit 4 is both ends open-ended pipe fitting, and the upper end of cylinder drill bit 4 is equipped with a plurality of and draw-in groove 30 matched with joint spare 40, the surface of joint spare 40 is equipped with the screw thread, it has fastening nut 5 to go back threaded connection on the connecting piece 3. The clamping piece 40 is clamped into the clamping groove 30 for connection, the clamping piece and the clamping groove are tightly connected through the fastening nut 5, and the barrel type drill bit is very convenient and stable to install and disassemble.
The thread on the outer surface of the clamping member 40 and the thread on the surface of the connecting member 3 have the same outer diameter, inner diameter, thread pitch and screwing direction. After the clamping member 40 is clamped into the clamping groove 30, the thread on the outer surface of the connecting member 40 and the thread on the surface of the connecting member 3 form a complete thread.
The number of the clamping pieces 40 and the clamping grooves 30 can be 4, 5 or 6. The quantity selection can be determined according to requirements.
The lower end of the barrel type drill bit 4 is provided with a circle of saw teeth. The convenient punching, cylinder drill 4 tells when rotatory, and 4 lower extremes of cylinder drill's sawtooth can be fast convenient saw out a hole.
The barrel type drill bit 4 and the clamping piece 40 are integrally formed and made of steel alloy materials. Ensuring sufficient hardness and increasing the service life.
The specific implementation mode and principle are as follows:
before punching generator cabin cover, insert the draw-in groove on the connecting piece 3 with the joint spare 40 of cylinder drill 4 upper end earlier to ensure that the screw thread on the two surface aligns, then rotatory fastening nut 5 makes fastening nut 5 cover at the junction of joint spare 40 and connecting piece 3, ensure that the two is connected closely, treat above preparation work and prepare the back of accomplishing, begin to punch again.
When punching, if the waste material card that the saw got off punches advances in cylinder drill bit 4, can take off the processing with cylinder drill bit 4 (need not take out the waste material promptly under the normal conditions, can punch after that, wait to block up more so that influence follow-up when punching retreating more), take off with the installation with the reason, unscrew fastening nut 5, then with cylinder drill bit 4 from connecting piece 3 pull out can, pull out the back, can use arbitrary ejecting (for example the thing of screwdriver class), from one of them one end of cylinder drill bit 4 with the waste material top out can, very convenient. The waste material is removed and the barrel drill 4 is mounted for subsequent drilling.
Based on the above, the utility model discloses simple structure uses in a flexible way, through setting up joint spare and draw-in groove for the cylinder drill bit is all very convenient when installation and dismantlement, sets up fastening nut simultaneously and can ensure that the cylinder drill bit is connected stably, and cylinder drill bit both ends are all open, when getting the waste material only need follow wherein one end with the waste material top out can, convenient and fast.
It will be appreciated by those skilled in the art that the invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The embodiments disclosed above are therefore to be considered in all respects as illustrative and not restrictive. All changes which come within the scope of the invention or which are equivalent to the scope of the invention are embraced by the invention.
