Abstract
The utility model discloses a special core bit that is used for power station gate water seal to drill, it includes the drill bit, the inside processing of drill bit has a drill bit through hole, and the head processing of drill bit has a sawtooth, the afterbody welding of drill bit in row material cylindrical in the heart, it has a row material through -hole to arrange the processing of material cylindrical center, has a row material window in row material cylindrical side processing, and the spliced pole is installed in row material cylindrical other end in the heart. This presss from both sides tight frock can carry out the tight operation of effectual clamp by counter shaft class part, prevents that it from taking place to rotate under great effect of the torque, and the surface of counter shaft class spare part carries out effectual protection.
Description
Technical field
This utility model belongs to hydroelectric facility apparatus for examination and repair technical field, a kind of special hollow drill bit removing use for power station steel-slag sand water seal.
Background technology
For the steel-slag sand in power station, water seal is to ensure that the core component of gate water sealing effect, owing to water seal belongs to rubber, life-time service is the most aging, therefore Jeakage through Sluice Sealant typically need to be replaced by power station every 4-8, when changing Jeakage through Sluice Sealant, need to hole water seal to install.
When water seal is holed by present stage, main using general hollow boring bit on the market to carry out work of holing, in use there is following convenient defect in this kind of hollow boring bit:
One, softer due to water seal rubber material, can expand after drill bit frictional heating, cause the socket cap rubber insert got out to be embedded in inside drill bit cylinder, thus cause extremely difficult taking-up, specific purpose tool need to be used during taking-up, waste time and energy.
Two, less due to water seal rubber skin-friction coefficient, the head zigzag of general hollow boring bit is less, easily skids when just having proceeded by bore operation, causes circular hole to bore askew, thus affects follow-up bore operation.
Utility model content
The purpose of this utility model is to provide a kind of special hollow drill bit for gate of hydropower station water seal boring; this clamping tool can carry out effective clamping operation to axial workpiece; prevent it from rotating under high torque effect, the outer surface of shaft element is effectively protected.
In order to realize above-mentioned technical characteristic, the technical solution adopted in the utility model is: a kind of special hollow drill bit for gate of hydropower station water seal boring, it includes drill bit, described drill bit internal is machined with drill bit through hole, the head of drill bit is machined with sawtooth, and the afterbody of drill bit is welded in discharge cylinder in the heart, and described discharge cylindrical center is machined with discharge through hole, it is machined with discharge window in the side of discharge cylinder, connects post and be arranged in the other end of discharge cylinder in the heart.
Described discharge window is symmetricly set on the two sides of discharge cylinder, and is connected with discharge through hole, discharges for material.
Described connection post bores with hand-held impact or bench drill is connected, and transmits torque.
The centrage of described drill bit, discharge cylinder and connection post overlaps.
The external diameter of described drill bit is 19mm.
This utility model has the advantages that:
When needing the boring of the water seal rubber structure to gate of hydropower station to take out, use this drill bit, connection post and hand-held impact are bored or bench drill the electric tool such as is connected and is connected, and then transmission moment of torsion, under the rotation connecting post, and then drive discharge cylinder to rotate, discharge cylinder drives drill bit to rotate, the sawtooth of drill bit carries out cutting drilling to the rubber sealed in hole, rubber is cut enters into drilling through in drill bit afterwards, discharge cylindrical inside is entered into through drill bit through hole, and then enter into discharge through hole, the outside of discharge cylinder it is discharged to eventually through discharge window, it is effectively prevented the elastomeric material accumulation at drill bit internal, prevent the blocking to drill bit, and facilitate the discharge of scrap rubber material, improve work efficiency and work quality, can promote the use of on a large scale.
Accompanying drawing explanation
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.
Fig. 1 is the main sectional view of this utility model.
Fig. 2 is the Section A-A figure in this utility model Fig. 1.
Fig. 3 is this utility model right view.
In figure: drill bit 1, sawtooth 2, drill bit through hole 3, discharge cylinder 4, discharge through hole 5, discharge window 6, connection post 7.
B: material discharge direction.
Detailed description of the invention
Below in conjunction with the accompanying drawings embodiment of the present utility model is described further.
As Figure 1-3, a kind of special hollow drill bit for gate of hydropower station water seal boring, it includes drill bit 1, described drill bit 1 is internal is machined with drill bit through hole 3, the head of drill bit 1 is machined with sawtooth 2, and the afterbody of drill bit 1 is welded in discharge cylinder 4 in the heart, and described discharge cylinder 4 center is machined with discharge through hole 5, it is machined with discharge window 6 in the side of discharge cylinder 4, connects post 7 and be arranged in the other end of discharge cylinder 4 in the heart.By using this kind of drill bit 1 that elastomeric material can be made easily to enter into drill bit internal, and then it is internal to enter into discharge cylinder 4, can be facilitated the storage of elastomeric material by discharge cylinder 4.
Further, described discharge window 6 is symmetricly set on the two sides of discharge cylinder 4, and is connected with discharge through hole 5, discharges for material.The expulsion efficiency of material is improve by two discharge windows 6.Prevent the rubber scrap blocking to discharge cylinder 4.
Further, described connection post 7 bores with hand-held impact or bench drill is connected, and transmits torque.By being connected with drilling equipment by connection post 7, it is possible to transmission moment of torsion, and then reach the function of boring.
Further, described sawtooth 2 shape is optimized, and is increased by the height of sawtooth, and spacing reduces, and is avoided that skidding, prevents circular hole from boring askew, improves work quality and work efficiency.
Further, the centrage of described drill bit 1, discharge cylinder 4 and connection post 7 overlaps.Be ensure that the transmission of moment of torsion by the centrage overlapped, improve work efficiency.
Further, the external diameter of described drill bit 1 is 19mm.The water seal bolt of hydraulic gate is generally M20, therefore the desirable 19mm of the external diameter of drill bit assembly, in order to ensure the water sealing effect of water seal.
Specific operation process of the present utility model is:
When needing the boring of the water seal rubber structure to gate of hydropower station to take out, use this drill bit, first, connection post 7 and hand-held impact are bored or bench drill the electric tool such as is connected and is connected, and then transmission moment of torsion, under the rotation connecting post 7, and then driving discharge cylinder 4 to rotate, discharge cylinder 4 drives drill bit 1 to rotate；Then, the sawtooth 2 of drill bit 1 carries out cutting drilling to the rubber sealed in hole, rubber is cut enter into afterwards in drill bit 1 drill through 3, enter into discharge cylinder 4 through drill bit through hole 3 internal, and then enter into discharge through hole 5；Finally, it is discharged to the outside of discharge cylinder 4 by discharge window 6, is effectively prevented elastomeric material in the accumulation within drill bit 1, prevent the blocking to drill bit 1, and facilitate the discharge of scrap rubber material, improve work efficiency and work quality, it is possible to promote the use of on a large scale.
