Abstract
A kind of glass punching machine, comprises cooling water pipe, commutator, motor shaft, and is placed in two bearings in commutator bore sleeve, a water inlet core pipe and black box; Two bearing holder (housing, cover)s are located at on water core pipe, and the outer end of water inlet core pipe is connected with cooling water pipe, and insert in the motor shaft of hollow after black box is worn in the inner of water inlet core pipe, motor shaft spins integral through the axle sleeve of connection screwed pipe and commutator.Black box is a set of mechanical sealing member, and this mechanical sealing member is arranged on described commutator bore sleeve near the side of motor shaft; The ring wall of commutator axle sleeve has a connecting bushing inner chamber and extraneous through hole.The utility model substitutes rubber seal with mechanical sealing member first on puncher commutator, is conducive to improving sealing property; After particularly offering through hole on commutator shaft cover, the water vapour that High Rotation Speed can be made to produce is discharged in time from the inner chamber of axle sleeve, avoids water vapour to be accumulated in bore sleeve, and infringement bearing affects complete machine work.
Description
Technical field
The utility model relates to a kind of glass working machine, especially belongs to a kind of glass punching machine.
Background technology
Glass punching machine drives the drill bit making High Rotation Speed, the cooling water pipe supplied water to drill bit by motor shaft, and is serially connected in the parts such as commutator between motor shaft and cooling water pipe and forms.Commutator comprises axle sleeve, and is arranged on two bearings in this bore sleeve, a water inlet core pipe and a rubber seal.Two bearing holder (housing, cover)s are located at on water core pipe, and the outer end of water inlet core pipe is communicated with cooling water pipe, the inner is passed from the mesopore of rubber seal, and insert the motor shaft of hollow, the axle sleeve of motor shaft through connecting screwed pipe and commutator spins integral.Before the utility model is made, there is following problems in this puncher: in operation, and commutator axle sleeve, with motor shaft High Rotation Speed, very easily causes rubber seal damage and occur leaking, cause cooling water to flow backwards and enter commutator inner chamber breaking-up bearing, affect complete machine work.
Summary of the invention
The utility model aims to provide a kind of glass punching machine, and these facility have seal not fragile, the advantage that sealing reliability is high.
For achieving the above object, the utility model have employed following technical proposals: this glass punching machine, comprises cooling water pipe, commutator, motor shaft, and is placed in two bearings in commutator bore sleeve, a water inlet core pipe and black box; Two bearing holder (housing, cover)s are located at on water core pipe, the outer end of water inlet core pipe is connected with cooling water pipe, the inner of water inlet core pipe is inserted in the motor shaft of hollow through after black box, the axle sleeve of motor shaft through connecting screwed pipe and commutator spins integral, it is characterized in that: described black box is a set of mechanical sealing member, this mechanical sealing member is arranged on described commutator bore sleeve near the side of motor shaft; The ring wall of described commutator axle sleeve has a connecting bushing inner chamber and extraneous through hole.
As preferably, described through hole is an axially extended rectangular through-hole.
As preferably, the area of described through hole is 2 × 30 ㎜
2.
Beneficial effect: compared with prior art, the utility model substitutes original rubber seal with mechanical sealing member first on puncher commutator, is conducive to improving sealing property; After particularly offering through hole on commutator shaft cover, the water vapour that high-speed rotary can be made to transfer to produce is discharged in time from the inner chamber of axle sleeve, avoids water vapour to be accumulated in bore sleeve, and infringement bearing causes the breaking-up of bearing.
Below in conjunction with accompanying drawing, by embodiment, the utility model is done into a bit describing.
Accompanying drawing explanation
Fig. 1 is the perspective view of the utility model embodiment.
In figure: motor 1, drill bit 11, commutator 2, through hole 21, cooling water pipe 3, steering knuckle 31, connects screwed pipe 4.
Detailed description of the invention
See Fig. 1.Tube drill 11 is fixed in the right-hand member of the motor shaft of motor 1.The left end of motor shaft spins integral through connecting screwed pipe 4 with axle sleeve 2 right-hand member of commutator.Cooling water pipe 3 is through steering knuckle 31 and water inlet core pipe (being positioned at axle sleeve 2) shape corner in 90 °, and the mouth of pipe of water inlet core pipe penetrates from the left end of commutator axle sleeve 2.In axle sleeve 2 inner chamber, from left to right, two bearing holder (housing, cover)s are located at on the pipe shaft of water core pipe, have both realized the sealing of axle sleeve 2 left end, realize again connecting between static water inlet core pipe and the axle sleeve 2 of High Rotation Speed.Water inlet core pipe continues to stretch to the right-hand member of commutator axle sleeve 2, and its mouth of pipe is through the motor shaft left end inserting hollow after the mesopore of mechanical sealing member.The both ends of the surface of axle sleeve 2 inner chamber are respectively the inner bearing face of two bearings and the sealing surface of mechanical sealing member, and this inner chamber is connected with extraneous via through holes 21.Through hole 21 is preferably offered along the axis of axle sleeve 2, and processing is more convenient like this, and the area of through hole 21 is with 2 × 30 ㎜
2as well.
Above-described embodiment only for explaining invention thinking, and should not be considered as the restriction to the utility model protection domain.
