Can explain the utility model in more detail by the following examples, the utility model is not limited to the following examples;
The grinding mechanism of 1～3 described a kind of bearing roller spherical end surface in conjunction with the accompanying drawings, adopt 5 pairs of workpiece of cylinder grinding wheel 17 to carry out grinding, the center line of described cylinder grinding wheel 5 for be horizontally disposed with or with the angled setting of horizontal plane, be provided with the spherical that caves inward in the end of cylinder grinding wheel 5, its spherical radius should equate with the spherical end surface radius of workpiece to be machined, in the hole of described cylinder grinding wheel 5, be provided with baffle plate 6, described baffle plate 6 is fixed in the endoporus of cylinder grinding wheel 5 by barrier support 7, baffle plate 6 in described cylinder grinding wheel 5 holes and barrier support 7 baffle plate 6 when changing the workpiece 17 of different model is adjustable in the axis direction position of cylinder grinding wheel 5, described barrier support 7 where necessary can be in the axis direction adjustment of cylinder grinding wheel 5, wherein cylinder grinding wheel 5 is arranged on a side of feed mechanism, feed table 18 outer rims in the described feed mechanism are provided with a plurality of V-shaped parts 28 that are used to deposit workpiece 17, described workpiece 17 carries out feeding by feed table 18 along cylinder grinding wheel 5 shaft sections, feed table 18 is arranged between right guide wheel 19 and the left guide wheel 29, described right guide wheel 19 is connected transmission mechanism respectively with left guide wheel 29, drives right guide wheel 19 and left guide wheel 29 respectively by transmission mechanism and is forward and reverse rotation and makes the V-shaped part 28 that is provided with on the feed table 18 drive the grinding area that workpiece 17 enter cylinder grinding wheel 5 continuously to carry out grinding.
The grinding mechanism of described bearing roller spherical end surface, described cylinder grinding wheel 5 be arranged on grinding wheel stand 16 above, described grinding wheel stand 16 advances by motor C15 and screw pair drive grinding wheel stand 16 and retreats, and cylinder grinding wheel 5 is by belt wheel A1, belt A 2, belt wheel B3 and motor A4 driven rotary.
The grinding mechanism of described bearing roller spherical end surface, wherein right guide wheel 19 by motor D 27 through decelerator B26, belt wheel F25, belt C23, belt wheel E22 and right guide wheel shaft 20 driven rotary, right guide wheel 19 be arranged on slide A above, described slide A horizontally slips by feed screw nut pair B24, a left side guide wheel 29 by motor B14 through decelerator A13, belt wheel D12, belt B10, belt wheel C8 and left guide wheel shaft 9 driven rotary, a left side guide wheel 29 be arranged on slide B above, described slide B horizontally slips by feed screw nut pair A11, be provided with mandrel 21 in the endoporus of right guide wheel shaft 20 or left guide wheel shaft 9, the end of described mandrel 21 is provided with feed table 18.
Implementation method of the present utility model is, at first workpiece 17 is sent into the V-shaped part 2 on feed table 18 tops, right guide wheel 19 and left guide wheel 29 are around self axis rotation, but its direction of rotation is opposite, after workpiece 17 entered spigot surface between right guide wheel 19 and the left guide wheel 29, workpiece 17 was around self axis rotation under the effect of frictional force between right guide wheel 19 and the left guide wheel 29; Because workpiece 17 can not rub mutually between each workpiece 17 by the separation of feed table 18; When the rotating speed of right guide wheel 19 during greater than the rotating speed of left guide wheel 29, workpiece 17 can revolve round the sun around feed table 18 center lines with half of both differentials; Owing in the hole of cylinder grinding wheel 5, be provided with baffle plate 6, drop in the hole of cylinder grinding wheel 5 when having avoided workpiece 17 effectively through cylinder grinding wheel 5 endoporus; Along with the continuous rotation of feed table 18, the workpiece 17 after the grinding can break away from V-shaped part 28 by band from grinding area under the effect of deadweight.
The utility model is in implementation process, and the center line of cylinder grinding wheel 5 is vertical with the center line of right guide wheel 19 with left guide wheel 29, and intersects in the symmetric position of left guide wheel 29 and right guide wheel 19 and the center line of left guide wheel 29 and right guide wheel 19.Tail end at the grinding wheel spindle of cylinder grinding wheel 5 is equipped with belt wheel A1, be with belt A 2 on the belt wheel A1, the other end of belt A 2 is enclosed within belt wheel B3, and belt wheel B3 connects with motor A4, grinding wheel stand 16 links with motor C15, and motor C15 finishes the forward and back and the compensating motion of cylinder grinding wheel 5 by the feed screw nut.
Wherein the operative end surface of cylinder grinding wheel 5 should be trimmed to the sphere of suitable radius before equipment carries out work.
The feed rate of workpiece 17 is to calculate like this: the rotating speed of supposing right guide wheel 19 is n1, the rotation speed n 2 of left side guide wheel 29, as n1 during greater than n2, workpiece 17 meetings are revolved round the sun around the center line of feed table 18 with the rotating speed of half n3 of both differentials, finish sending to and grinding process through cylinder grinding wheel 5 spherical end surfaces.In this process, feed table 18 is being pushed away passively speed with n3 around self axis rotation by workpiece 17, but feed table 18 plays a part to separate workpiece 17 and control workpiece 17 directions again conversely, and it has very important influence to crudy.
Wherein the size of n3 has determined that feeding speed is a production efficiency, and too small-scale production efficient of n3 is low, and it is unfavorable to crudy that n3 crosses conference, and this need decide according to factors such as the actual size of workpiece 17 and allowance sizes.N3 is calculated as follows:
n3=?(n1-n2)/2
The rotation speed n 1 of right guide wheel 19 can be by carrying out frequency control to motor D 27, and the rotation speed n 2 of left guide wheel 29 can be by carrying out frequency control to motor B14, thereby can realize the revolution speed of workpiece 17 is adjusted arbitrarily.
Wherein the material loading of workpiece 17, send to, grinding, blanking be to carry out continuously synchronously, the choose reasonable operation parameter can obtain desirable production efficiency.
Driving member in the above-mentioned embodiment can change under different situations, and for example belt and belt wheel also can adopt chain and sprocket wheel or the like.
