Description
Technical field
The utility model belongs to quartzy process equipment field, particularly relates to a kind of mill elevating mechanism that is applied on quartzy grinding or the polishing machine.
Background technology
Publication number is that the patent documentation of CN2748220Y discloses a kind of crystal flour-milling machine with liftable millstone, it is designed to the inside and outside sleeve structure, outer sleeve is fixed on the frame, rotate in the inner sleeve mill spindle is set, in outer sleeve one side axially open is set, and on inner sleeve, be provided with the corresponding position of axially open, be provided with and the tooth bar meshed gears in the outer sleeve outside, reach the purpose of lifting mill by transmitting gear.Such structure moves up and down in the process at inner sleeve, has bigger wearing and tearing between inner sleeve and the outer sleeve, has a strong impact on the service life of machine.
Publication number is that the patent documentation of CN201009143Y discloses the quartzy facet machine of a kind of full-automatic mill lift, employing is with the same inside and outside sleeve structure of above-mentioned document, but the elevating mechanism difference of inner sleeve, inner sleeve is connected with lifting frame, lifting frame is connected with wire rod thread on the frame that is arranged on outer sleeve below, though such structure can reduce the wearing and tearing of inside and outside sleeve, but, also increased the height of frame and mill, not only use inconvenient operation, and increase material cost and influence the machine stationarity.
Summary of the invention
In order to solve above-mentioned technical problem, the purpose of this utility model provides a kind of mill elevating mechanism of quartzy grinding and polishing machine, not only can reduce the wearing and tearing of inside and outside sleeve, guarantee the service life of machine, and the mill height is low, volume is little, compact conformation.
To achieve the above object, the utility model has adopted following technical scheme:
A kind of mill elevating mechanism of quartzy grinding and polishing machine, comprise the outer sleeve that is fixed on the frame, be provided with inner sleeve moving up and down in the outer sleeve, rotating mill spindle is set in the inner sleeve, the mill spindle upper end is provided with mill, the mill spindle lower end is connected by the belt wheel that spline and rotation are arranged on the outer sleeve bottom, belt wheel connects rotary electric machine, described outer sleeve one side is provided with axially open, be connected with the connecting rod that stretches out this axially open on the described inner sleeve, connecting rod is connected with the wire rod thread that rotation is arranged on the frame, and the lifting motor on described screw mandrel and the frame is in transmission connection, wherein, described inner sleeve is provided with the wear-resistant sleeve that contacts with outer sleeve.
As preferably, above-mentioned screw mandrel is a ball screw, the ball nut cover that has been threaded on the ball screw, and described connecting rod is connected with the ball nut cover.
As preferably, above-mentioned inner sleeve is provided with at least two wear-resistant sleeves, is provided with oil storage tank between the adjacent wear-resistant sleeve.Oil lubrication is set, to reduce wear between inside and outside sleeve.
As preferably, be provided with telescopic protective cover between above-mentioned outer sleeve top and the inner sleeve.Protective cover can prevent that sealing, mill slag enter and cause wearing and tearing between the inside and outside sleeve.
The utility model is owing to adopted above technical scheme, employing is at the affixed connecting rod of a side of inner sleeve, connecting rod is connected with wire rod thread, by lifting motor rotary screw rod and then driving connecting rod and connected inner sleeve lifting, make like this lifting motor and screw mandrel needn't be arranged on outer sleeve under and can be arranged on the one side, reduced mill and bracket height; Employing is provided with wear-resistant sleeve on inner sleeve, guaranteed the case hardness of inside and outside sleeve and the wearing and tearing that flatness can reduce both, increases oil lubrication again and can obtain better effect.Therefore, the utlity model has that inside and outside sleeve wearing and tearing are little, long service life, rational in infrastructure, advantage such as volume is small and exquisite, machine operates steadily.
