A flange is arranged at one end of the main axis, the other end has a screw thread, the adamas roller and the flange and the screw thread at the main axis are tightly fixed at the outside of the main axis by the fastened nut, and a supporting head nut is arranged at the fastened nut. The device can effectively improve the supporting rigidity and the returning precision of the main axis, simultaneously is convenient for installing and adjusting.
Description
Technical field
This practical technique belongs to a kind of grinding machine components, refers in particular to the structure member of the used dresser of grinding machine of a kind of deep groove ball bearing of processing hub bearing outer ring or two raceways and taper roll bearing outer ring.
Background technology
The processing hub bearing adopts the forming grinding wheel grinding more, is repaired out the shape of forming grinding wheel by emery wheel.The shape and size correct grinding that emery wheel is trimmed out will directly have influence on the technical parameter index and the dimensional accuracy of workpiece to be machined, therefore require the emery wheel main shaft that higher rigidity, dimensional accuracy and rotating accuracy are arranged.Because emery wheel has certain service life, therefore also require trimmer on structure, can be convenient to changeing and adjusting of emery wheel.
In the prior art, the structure that the emery wheel main shaft that uses on the grinding machine is adopted is a kind of cantilevered structure that is similar to, be that emery wheel is at rolling bearing supporting-point another side, though be convenient to the dismounting of emery wheel, but therefore reduced the rigidity of roller main shaft, be easy to generate vibration, also reduced the rotating accuracy of main shaft.
The utility model content
The purpose of this utility model is to design a kind of numerical control hub bearing outer ring ditch grinding machine emery wheel mainshaft mechanism, so that improve the supporting rigidity of main shaft and the rotating accuracy of main shaft, and convenient simultaneously the installation and adjustment.
According to scheme provided by the utility model, utilize bearing to connect splicing sleeve respectively at the two ends of main shaft, at the middle part of main shaft emery wheel is installed, in main shaft inside axle is arranged, at an end of axle drive is installed.
Its further feature is: the end at main shaft is provided with flange, and the other end has screw thread, and emery wheel utilizes the flange on fastening screw nut and the main shaft and is screwed to outside the main shaft, and branch head screw is set on fastening screw nut again.End installation at the close drive of axle is used to locate the shaft-cup of drive, and is used for the bearing cap of location bearing, also is provided for the bearing cap of location bearing at the other end of axle.End at splicing sleeve is provided with end cap, and dish-like nut is set between end cap and bearing.
The utility model has the advantages that: owing to all utilize high-precision in groups angular contact ball bearing to install, compare, improved the supporting rigidity of main shaft on the one hand, also improved the rotating accuracy of main shaft simultaneously with original cantilever structure at the main shaft two ends.After being provided with disk spring between bearing and the end cap, can control the pretightning force of bearing by the degree that compresses of disk spring, more convenient.The organic assembling of main shaft and axle and splicing sleeve is for installing and adjustment provides convenience.
Description of drawings
Fig. 1 is the structure chart of utility model.
The specific embodiment
As shown in the figure: 1, dish-like nut, 2, bearing cap, 3, end cap, 4, splicing sleeve, 5, angular contact ball bearing, 6, main shaft, 7, fastening screw nut, 8, fastening nail, 9, splicing sleeve, 10, bearing cap, 11, motor, 12, belt pulley, 13, belt, 14, sealing ring, 15, key, 16, shaft-cup, 17, belt pulley, 18, angular contact ball bearing, 19, clamp, 20, emery wheel.
Utilize bearing 5,18 to connect splicing sleeve 4,9 at the two ends of main shaft 6 respectively, at the middle part of main shaft 6 emery wheel 20 is installed, in the inside of main shaft 6 axle 21 is arranged, the main shaft of this separate assembling is convenient to processing and is made, and at an end of axle 21 drive 17 is installed.Emery wheel main shaft 6 can be by clamp 19 integral installations on the trimmer seat together with emery wheel 20, and during work, actuating motor 11 drives belt pulley 17 by belt pulley 12 by belt 13 and rotates, and drives main shaft 6 and emery wheel 20 rotations by key 15 again.The used bearing 5,18 in main shaft 6 two ends is high-precision angular contact ball bearing in groups, and the supporting rigidity that this can improve main shaft 6 has on the one hand also improved the rotating accuracy of main shaft 6 on the other hand.
End at main shaft 6 is provided with flange 22, and the other end has screw thread, and emery wheel 20 utilizes the flange on fastening screw nut 7 and the main shaft 6 and is screwed to outside the main shaft 6, and branch head screw 8 is set on fastening screw nut 7 again.What adopt between emery wheel 20 and the main shaft 6 is interference fit, can avoid the gap that exists between hole, the axle like this and causes that emery wheel main shaft 6 beats.Branch head screw 8 wherein is used to locate fastening screw nut 7.
End installation at axle 21 close drives 17 is used to locate the shaft-cup 16 of drive 17, and is used for the bearing cap 10 of location bearing 18, also is provided for the bearing cap 2 of location bearing 5 at the other end of axle 21.In the end of splicing sleeve 4 end cap 3 is set, dish-like nut 1 is set between end cap 3 and bearing 5.The pretightning force of bearing 5,18 is controlled by the degree that compresses of disk spring 1.
