Description

A kind of intaglio plate grinder main shaft waterproof construction

Technical field

The utility model is related to a kind of intaglio plate main shaft structure of grinding machine more particularly to a kind of intaglio plate grinder main shaft waterproof knots Structure.

Background technology

For gravure printing roller is made to obtain good finished surface in the production process, made before steel rider roller embryo copper facing with copper roller Before picture and text, processing is often ground to roller.Intaglio plate grinding is right under pressure with high-speed rotating abrasive sand wheel disc Intaglio plate surface is carried out repeatedly after milled processed to obtain the processing method of good finish and concentricity.In abrasive sand wheel disc and Cool water shower device is provided at roller, while the cooling water sprayed can wash away the abrasive grain on roller surface, reduce it Influence to following process.

To prevent the cooling water for being mingled with abrasive grain from being impacted to roller live spindle drive mechanism, it is equipped on main shaft anti- Water-bound.Existing waterproof construction is as shown in Figure 1 using drip ring and outside framework oil seal water blocking, structure.The structure is often because rotation is led Axis and waterproof jacket gap are improper, skeleton oil seal does not make sternly the cooling water of entrainment abrasive grain enter in bearing, influence making for bearing Use the service life.

Utility model content

The purpose of this utility model is exactly overcome the deficiencies in the prior art, and provides a kind of more efficiently intaglio plate grinder Main shaft waterproof construction.

To achieve these goals, the technical solution adopted in the utility model is：

A kind of intaglio plate grinder main shaft waterproof construction, including main shaft, improvement rear support, connection ring, rotatory sealing after improvement Ring, improves rear pressing cover at fixing seal ring, it is characterised in that：After the improvement main shaft by thrust bearing, radial ball bearing and Locking nut, which is mounted on, to be improved on rear support；The improvement rear support is welded by section bar, is improved rear pressing cover and is passed through cylinder Head screw c compresses the outer ring of the outer ring of thrust bearing, spacer and radial ball bearing；Have in the connection ring threaded hole b, Stepped hole b, connection ring are fixed on after improvement by holding screw on main shaft；Have on the rotating seal ring inner ring place it is O-shaped The o-ring groove a of sealing ring a, rotating seal ring are connect by fillister head screw e with connection ring, connection ring and rotating seal ring It is rotated with main shaft after improvement；There is the groove for placing O-ring seal b on the improvement rear support, improve rear pressing cover and pass through Fillister head screw d compresses O-ring seal b；There is stepped hole a on the fixing seal ring；Have on the improvement rear pressing cover The threaded hole of the groove of placement O-ring seal c, the stepped hole for wearing fillister head screw c and installation fillister head screw d, O-ring seal C is compressed by fixing seal ring and fillister head screw d；There are certain intervals between rotating seal ring and fixing seal ring.For The clamping that roller clamps is top i.e. usable on main shaft after improving.

Compared with prior art, the beneficial effects of the utility model are：Traditional drip ring and outside framework oil seal water blocking are changed For the waterproof construction of the compositions such as rotating seal ring and fixing seal ring, the adjustment difficulty in static and dynamic sealing link gap is reduced, is subtracted The small cooling water with abrasive grain enters the probability in bearing, improves the service life of bearing, extends the maintenance week of equipment Phase.

Specific embodiment

Fig. 1 is existing main shaft waterproof construction schematic diagram, mainly includes the conventional master spindle 2 with water blocking groove 3, drip ring 4, passes System gland 5, thrust bearing 7, radial ball bearing 9, rubber oil sea 11 etc..As shown in Figure 1, the clamping top 1 clamped for roller On conventional master spindle 2, conventional master spindle 2 passes through thrust bearing 7, radial ball bearing 9 and locking nut（It is not drawn on figure）Deng On traditional bearing 8, traditional bearing 8 is welded by section bar, and traditional gland 5 is by fillister head screw a6 by thrust bearing The outer ring of 7 outer ring, spacer 10 and radial ball bearing 9 compresses.The groove of rubber oil sea 11 is machined on traditional gland 5, is kept off Water ring 4 is compressed rubber oil sea 11 by fillister head screw b12.Fixed drip ring 4 and rotation conventional master spindle 2 between there are Small―gap suture, conventional master spindle 2 are pasting the gear being machined on the diameter of axle in top 1 direction of close clamping faced for water blocking with drip ring 4 Water groove 3.

Fig. 2 is the utility model main shaft waterproof construction schematic diagram, unlike Fig. 1, eliminates drip ring 4 and rubber oil Envelope 11, for roller clamp clamping top 1 be mounted on improve after main shaft 13, after improvement main shaft 13 by thrust bearing 7, to Heart ball bearing 9 and locking nut（It is not drawn on figure）It is improved on rear support 20 Deng being mounted on, improves rear support 20 and welded by section bar It forms, improving rear pressing cover 22 will be outside the outer ring of thrust bearing 7, spacer 10 and radial ball bearing 9 by fillister head screw c19 Circle compresses.Connection ring 15 is fixed on by holding screw 14 after improvement on main shaft 13, and rotating seal ring 17 passes through fillister head screw E25 is connect with connection ring 15, there is the groove for placing O-ring seal a16 on 17 inner ring of rotating seal ring, and connection ring 15 and rotation are close Seal ring 17 is rotated with main shaft after improvement 13.The groove for having on rear support 20 and placing O-ring seal b21 is improved, is pressed after improvement Lid 22 is compressed O-ring seal b21 by fillister head screw c19, improve have on rear pressing cover the groove for placing O-ring seal c24, It wears the stepped hole of fillister head screw c19 and the threaded hole of installation fillister head screw d23, O-ring seal c24 passes through fixing seal ring 18 and fillister head screw d23 is compressed.There are certain intervals between rotating seal ring 17 and fixing seal ring 18.
