Boring, the T-shaped water-drainage type seal device of milling unit head.
The utility model boring, the technical scheme of T-shaped water-drainage type seal device of milling unit head are to include the master of unit head
Axle, protecgulum, bearing cage and bearing are installed outside main shaft, the cutter holes of installation cutter are formed with main shaft, bearing cage matches with bearing
Close, it is characterised in that described spindle outer wall is formed with T-shaped connection ring, and described protecgulum inwall is formed with groove and baffle ring, in axle
The side for holding cover is formed with back-up ring, and protecgulum is in contact with bearing cage, and the side of T-shaped connection ring is arranged in the groove of protecgulum, and
Corresponding with baffle ring, the opposite side of T-shaped connection ring is engaged with bearing cage, and corresponding with back-up ring, and the groove of protecgulum is formed
Water storage tank, the osculum communicated with water storage tank is formed with protecgulum.
It the utility model is related to a kind of T-shaped water-drainage type seal device for the unit head for being used for boring machine or milling machine, including power
The main shaft of head, installs protecgulum, bearing cage and bearing outside main shaft, and the cutter holes of installation cutter, bearing cage and axle are formed with main shaft
Hold and be engaged, it is mainly technically characterized by being formed with T-shaped connection ring in spindle outer wall, and described protecgulum inwall is formed with groove and gear
Ring, back-up ring is formed with the side of bearing cage, protecgulum is in contact with bearing cage, and the side of T-shaped connection ring is arranged on the recessed of protecgulum
In groove, and corresponding with baffle ring, the opposite side of T-shaped connection ring is engaged with bearing cage, and corresponding with back-up ring, protecgulum it is recessed
Groove forms water storage tank, and the osculum communicated with water storage tank is formed with protecgulum.T-shaped connection ring and protecgulum inwall outside by main shaft
In baffle ring and the back-up ring of groove and bearing cage inwall composition sealing mechanism, prevented by the sealing mechanism from unit head to knife
Have the coolant used to enter in bearing, the water storage tank that the osculum and protecgulum groove particularly in protecgulum are formed, make entrance
Coolant in water storage tank（Cooling water）It is discharged to by osculum outside protecgulum, and the osculum is either in the work of unit head
Make state, or inactive state, can be by the coolant in water storage tank（Cooling water）Constantly, timely discharge, keep away completely
Exempt from coolant to enter in bearing, effectively overcome because coolant enters the problem of causing bearing damage after bearing, and because originally
Sealing device is by the structural change to main shaft, protecgulum and bearing cage, without consumable accessorys such as sealing ring or sealing rings, so originally
Sealing device has：Wear small or without abrasion, the features such as service life is long.
The utility model boring, the T-shaped water-drainage type seal device of milling unit head, T-shaped connection ring one end on the main shaft
Bulge loop is formed with, bulge loop is engaged with the inwall of protecgulum, there is bulge loop, increases the sealing effectiveness between protecgulum and bearing cage, more has
Discharged beneficial to the coolant in water storage tank from osculum, further prevent coolant from entering in bearing, ensure the safety of bearing
Use.It is engaged between described protecgulum and bearing cage by convex tendon with recess, convex tendon is connected with recess, makes protecgulum and bearing
It is closer that both coordinate cover.

Embodiment
A kind of boring, the T-shaped water-drainage type seal device of milling unit head are the utility model is related to, as shown in Fig. 1-Fig. 4, including
The main shaft 1 of unit head, protecgulum 2, bearing cage 3 and bearing 4 are installed outside main shaft 1, the cutter holes of installation cutter are formed with main shaft 1
13, bearing cage 3 is engaged with bearing 4, and it is mainly technically characterized by being formed with T-shaped connection ring 11 in the outer wall of main shaft 1, before described
The inwall of lid 2 is formed with groove 21 and baffle ring 22, and back-up ring 31 is formed with the side of bearing cage 3, and protecgulum 2 is in contact with bearing cage 3, T words
The side of shape connection ring 11 is arranged in the groove 21 of protecgulum 2, and corresponding with baffle ring 22, the opposite side of T-shaped connection ring 11
It is engaged with bearing cage 3, and it is corresponding with back-up ring 31, and the groove 21 of protecgulum 2 forms water storage tank 23, is formed with protecgulum 2 and product
The osculum 24 that tank 23 communicates.T-shaped connection ring 11 outside by main shaft 1 and the baffle ring 22 in the inwall of protecgulum 2 and groove 21 with
And the back-up ring 31 of the inwall of bearing cage 3 forms sealing mechanism, the cooling for preventing from using cutter from unit head by the sealing mechanism
Liquid enters in bearing, the water storage tank that the osculum and protecgulum groove particularly in protecgulum are formed, makes cold into water storage tank
But liquid（Cooling water）It is discharged to by osculum outside protecgulum, and the osculum is either in the working condition of unit head, or
Inactive state, can be by the coolant in water storage tank（Cooling water）Constantly, timely discharge, avoid coolant from entering completely
In bearing, effectively overcome because coolant enters the problem of causing bearing damage after bearing, and because this sealing device is logical
The structural change to main shaft, protecgulum and bearing cage is crossed, without consumable accessorys such as sealing ring or sealing rings, so this sealing device has
Have：Wear small or without abrasion, the features such as service life is long.One end of T-shaped connection ring 11 on the main shaft 1 is formed with bulge loop 12,
Bulge loop 12 is engaged with the inwall of protecgulum 2, there is bulge loop, is increased the sealing effectiveness between protecgulum and bearing cage, is more beneficial for accumulating
Coolant in tank is discharged from osculum, is further prevented coolant from entering in bearing, is ensured the safe handling of bearing.Institute
It is engaged between the protecgulum 2 stated and bearing cage 3 by convex tendon 25 with recess 32, convex tendon is connected with recess, makes protecgulum and bearing
It is closer that both coordinate cover.
