Abstract
A device for grinding two ferrules at a same time is provided, which is characterized in that: a central line for a grinding machine positioning cylinder is inclined downwards; the inclination angle equals the gradient of the work piece; a bracket for a clamp on the positioning cylinder can be inclined downwards with same angle; two position limiting brackets connected vertically to the bracket are positioned on the bracket; a work surface of a top block under each position limiting bracket corresponds respective to a work piece bushed in parallel on a column grinding wheel; the distance between the work surfaces of two top block equals 1/2 of the difference between the large inner diameter and the small inner diameter of the work piece. Therefore, the utility model can not only boost the production efficiency by one time, but also save the investment on the configuration of taper grinding wheel with diversified specification.
Description
Technical field the utility model relates to a kind of grinding machine.
Background technology is present, grinding to the outer raceway of single-row tapered roller bearing lasso, basically still on the grinding machine of existing structure, carry out, promptly be fixed with anchor clamps on the top of this grinding machine positioning tube, it has a bar shaped support parallel with the positioning tube center line, establish the strip through-hole parallel with the positioning tube center line on it, the bolt that passes this strip through-hole also passes the strip through-hole of limiting bracket, and limiting bracket is vertically fixed on the support.Be provided with jacking block in the limiting bracket lower end, its can with the emery wheel acting in conjunction, with the top of workpiece folder within it.This emery wheel is the tapering circular cone emery wheel identical with the workpiece to be machined tapering.Its weak point is: once can only grind a workpiece, efficient is very low; And the tapering difference of workpiece will change the emery wheel of different taperings, and not only troublesome poeration also needs expensive fund to get all the these emery wheels ready.
The summary of the invention the purpose of this utility model is to provide a kind of device with two lassos of a grinding of cylindrical grinding wheel.The utility model mainly is based on existing grinding machine, but will make the positioning tube center line downward-sloping, and its inclination angle promptly equals the tapering of workpiece machined surface with the folded acute angle of horizontal plane.The also downward-sloping thereupon same angle of anchor clamps on the positioning tube.On these anchor clamps, be provided with two and support limiting bracket connected vertically, the working face of jacking block is respectively corresponding with a workpiece again below each limiting bracket, and the distance between two jacking block working faces equals 1/2 of workpiece large diameter and the little internal diameter difference of workpiece, can make the interior raceway top of two workpiece be straight line like this, and this straight line is parallel with grinding wheel bearing again.The horizontal rotating shaft of grinding machine is provided with cylinder emery wheel, and when grinding, two workpiece are enclosed within on the cylindrical grinding wheel side by side, and their interior raceway top contacts with emery wheel, and the outer peripheral face of this two workpiece then contacts with two jacking blocks respectively.When the rotating shaft of emery wheel is turned round, cylindrical grinding wheel can carry out grinding to the tapered raceway of two workpiece, in addition in these two workpiece arranged side by side, the end face of a workpiece can contact with positioning tube, establish the locating part corresponding that is fixed on the grinding machine near being preferably in the end face of another workpiece, in order to the displacement that stops this two workpiece to produce horizontal direction when the grinding with the workpiece bottom.This locating part can have multiple version, and simpler structure is a fork, and its lower end is hinged on the grinding machine, and the upper end is a free end, and it can hinge be that axle rotates, and fork can be forwarded to the position of holding up when grinding, so it can block workpiece; Grinding then forwards fork to the position that keeps flat when finishing, so that workpiece loading and unloading.For guaranteeing that support is vertical with limiting bracket, preferably fixture mount is provided with two strip through-holes arranged side by side, then is provided with two fastening bolts on each limiting bracket.
The utility model has following advantage compared to existing technology: 1. corase grind production efficient can improve about 60%, and fine grinding production efficient can improve about one, and no matter is corase grind or its oval improvement all more than 50% of fine grinding.2. adopt cylindrical grinding wheel can process the workpiece of various taperings, saved the investment that is equipped with plurality of specifications circular cone emery wheel.
Description of drawings
Fig. 1 is that the utility model user mode master looks generalized section.
Specific embodiment duty is looked in the generalized section the user mode master of the device of two lassos of a grinding shown in Figure 1, grinding machine positioning tube 1 top is fixed with anchor clamps, it has a support parallel with the positioning tube center line 2, this support is provided with two strip through-holes parallel with the positioning tube center line, the bolt that passes cylindrical void also passes the strip through-hole of limiting bracket 3, and limiting bracket is vertically fixed on the support.Above-mentioned positioning tube center line is downward-sloping, and its inclination angle equals the tapering of workpiece 4.The also downward-sloping thereupon same angle of the support of anchor clamps on the positioning tube.Respectively establish a jacking block 5 below above-mentioned two limiting brackets, each is corresponding with a workpiece that is enclosed within side by side on the cylindrical grinding wheel 6 for its working face, and the distance between two jacking block working faces equals 1/2 of workpiece large diameter and the little internal diameter difference of workpiece.Be provided with the locating part corresponding with the workpiece bottom on grinding machine, it is hinged on the fixture 7 for the lower end, and the upper end is free-ended fork 8.
Claims (3)
1. device of two lassos of grinding once, its grinding machine positioning tube top is fixed with anchor clamps, it has a support, this support is provided with the strip through-hole parallel with the positioning tube center line, the bolt that passes this cylindrical void also passes the strip through-hole of limiting bracket, limiting bracket is vertically fixed on the support, be provided with jacking block in the limiting bracket lower end, it can press from both sides within it with the top of emery wheel with workpiece, it is characterized in that: the positioning tube center line is downward-sloping, its inclination angle equals the gradient of workpiece, the also downward-sloping same angle of the support of anchor clamps on the positioning tube, on this support, establish two with support limiting bracket connected vertically, the working face of jacking block can each be corresponding with a workpiece that is enclosed within side by side on the cylindrical grinding wheel below each limiting bracket, and the distance between two jacking block working faces equals 1/2 of workpiece large diameter and the little internal diameter difference of workpiece.
2. the device of two lassos of a grinding according to claim 1, it is characterized in that: fixture mount is provided with two strip through-holes arranged side by side, and each limiting bracket then is provided with two fastening bolts.
3. the device of two lassos of a grinding according to claim 1 and 2 is characterized in that: be provided with the locating part corresponding with the workpiece bottom on grinding machine.
