As a kind of perferred technical scheme, the elevating mechanism includes a lifting for being mounted on the spindle box bottom Seat, is provided with two optical axises and two ball-screws being vertically arranged below the lifting seat, two optical axises and two The ball-screw is oppositely arranged, and an erecting bed, each optical axis and each institute are equipped between the optical axis and ball-screw It states ball-screw and both passes through the erecting bed, be additionally provided with lifting motor and lifting decelerator on the erecting bed.

As a kind of perferred technical scheme, the main shaft and the pull rod are set to the blind rivet on the main shaft by one It is attached.

As a kind of perferred technical scheme, one end of the stretching spindle box of the pull rod is equipped with a cylinder, institute It states main shaft and stretches out one end of spindle box equipped with water blocking metal plate.

As a kind of perferred technical scheme, the shrapnel group includes several elastic slices, is mutually pushed up between the adjacent elastic slice It is close together.

As a kind of perferred technical scheme, the main shaft is BT40 main shaft.

As a kind of perferred technical scheme, the front end of the collar bush reaches Rockwell hardness 48-55 through Overheating Treatment.

The another technical solution of the utility model is achieved in that

The environmentally friendly numerical control mo(u)lding machine of the fast quick change grinding head device, including rack, the side of the rack are provided with one Crossbeam is horizontally arranged with seven fast quick change grinding head devices on the crossbeam, is additionally provided on the crossbeam and passes for driving Send the speed reducer of band.

As a kind of perferred technical scheme, different types of mill is separately installed on each fast quick change grinding head device The shape of head.

Using above-mentioned technical proposal, the utility model has the following beneficial effects:

Since fast quick change grinding head device includes threephase asynchronous machine, one first is provided on the transmission shaft of threephase asynchronous machine Synchronizing wheel is equipped with a spindle box below threephase asynchronous machine, and spindle box includes a collar bush being fixed in spindle box, main It is arranged with one second synchronizing wheel on the corresponding position of axle sleeve, synchronous belt is provided between the first synchronizing wheel and the second synchronizing wheel, it is main By a pull rod in axle sleeve, one end of pull rod is connected with main shaft, and main shaft stretches out spindle box far from one end of pull rod, pull rod it is another Spindle box is stretched out at end, is arranged with a shrapnel group in the middle part of pull rod, and shrapnel group abuts against an elastic slice locknut being set on pull rod, In use, threephase asynchronous machine drives the first synchronizing wheel to be rotated, so that synchronous belt and the second synchronizing wheel is driven to be rotated, And then collar bush rotation is driven, the rotation of collar bush drives pull rod rotation, and pull rod can generate huge pulling force by elastic slice, in turn Main axis is driven, the spindle box form that the utility model uses drives spindle box using threephase asynchronous machine, to drive master Axis rotation, the main shaft threephase asynchronous machine form used than in the prior art is more durable, and is not likely to produce " horn mouth ", prolongs significantly The service life for having grown the utility model, takes full advantage of bistrique.

Due to being provided with an elevating mechanism below spindle box, elevating mechanism includes a lifting for being mounted on spindle box bottom , two optical axises and two ball-screws being vertically arranged, two optical axises and two ball-screws are provided with below lifting seat It is oppositely arranged, an erecting bed is equipped between optical axis and ball-screw, each optical axis and each ball-screw both pass through erecting bed, pacify It is additionally provided with lifting motor and lifting decelerator on dress platform, elevating mechanism can control main shaft and be moved in the vertical direction, The bistrique of multiple types can be installed on mo(u)lding machine, what moulding is needed directly to use, reduce replacement bistrique Time, and replacement bistrique moulding can generate a large amount of dust, to reduce the generation of exhaust gas.

Since main shaft is attached with pull rod by a blind rivet being set on main shaft, when in use, pull rod passes through elastic slice Huge pulling force can be generated, and then realizes the rotation of main shaft, grinding spindle and spindle box are separated, so that being not likely to produce on main shaft " horn mouth ", on the other hand, but also to change bistrique convenient and efficient by operator.

Since one end of the stretching spindle box of pull rod is equipped with a cylinder, the utility model uses pneumatic form, will grind Main shaft and the spindle box of head separate, and avoid " horn mouth " occur on main shaft, extend the service life of the utility model, so that mill Head is fully utilized.

Since the front end of collar bush is through Overheating Treatment, reaches Rockwell hardness 48-55, be not susceptible to deform, and has certain Toughness, ensure that collar bush will not damage during rotation, and be not easy occur " horn mouth ".

Due to being separately installed with the shape of different types of bistrique on each fast quick change grinding head device, the shape of bistrique can be with Many types are kept, without constantly changing shape on a bistrique.It is every change a kind of shape must be again to bistrique, reconditioning Head.The bistrique moulding of needs is carried out in advance in new technology, what moulding needed, is directly loaded onto, the distance of front and back does not need to adjust Section, so that operator changes, bistrique is convenient and efficient, reduces the generation of exhaust gas, takes full advantage of bistrique.
