The utility model is comprised of workpieces, a workpiece case, coreless cards, a grinding wheel, a grinding head, a grinding wheel main shaft, a grinding wheel bracket, and a swing friction plane. Workpieces are arranged on coreless cards of the workpiece case; the swing friction plane is a sliding plane supporting the workpiece case and workpiece case horizontal and vertical moving guide rail; and the grinding wheel is fixedly arranged at the front end of the grinding wheel main shaft by the grinding wheel bracket.
Description
Technical field
The utility model relates to the grinding machine equipment field, concretely, relates to a kind of large-scale reciprocally swinging groove grinder.
Background technology
At bearing industry, the inner ring of ball-track, outer ring not only specification are many, and the large product that surpasses φ 200 circles is very many, be processed into the part of spherical raceway groove at present for needs, two kinds of processing methods are generally arranged, and a kind of is to utilize the emery wheel grinding tool to do globulate, carries out grinding work piece, be called the molding cutter grinding, another kind of method is that workpiece is contained on the workpiece box that can swing.The problem that first method exists is that after the forming grinding wheel cutter consumed, size changed, and has influenced the quality of spherical product; The ubiquitous processing characteristic of the device that adopts in the second method be passive to workpiece box be a bigger main shaft, spindle centerline is exactly an oscillation center, workpiece box and portraitlandscape adjusting device thereof all concentrate on the end face of main shaft, form a cantilever design.The Area of bearing of cantilever design is little, supports unstable.And can only process the following product of small-sized φ 200 circles, because main shaft can not be infinitely great.Prior art does not satisfy the equipment needs of the large-scale ball track of the φ 200 above bearing ring needs grindings of circle.
Summary of the invention
In order to solve the problems of the technologies described above, the purpose of this utility model provides a kind of large-scale reciprocally swinging groove grinder.The cantilever design defective that the utility model has solved grinding machine spindle supporting workpiece case in the past is little with the Area of bearing of swing frictional plane cantilever design, supports unsettled shortcoming.
The utility model by workpiece, workpiece box, be not in the mood for card, emery wheel, bistrique, grinding wheel spindle, grinding carriage, swing friction tapered plane constitutes; Workpiece is installed in not being in the mood on the card of workpiece box, and swing friction tapered plane is supporting workpiece case and the workpiece box slip plane of moving guide rail in length and breadth, and emery wheel is fixedly mounted on the grinding wheel spindle front end of bistrique by grinding carriage.
Described workpiece box can be along two orthogonal directions adjustment in horizontal plane, so that the ball receway center of workpiece overlaps with the oscillation center of lathe.
Described bistrique drives emery wheel can hand feed on perpendicular to the grinding wheel spindle centerline direction, can manually adjust being parallel on the grinding wheel spindle centerline direction, can adjust to vertical emery wheel direction of axis line, the spherical raceway groove of the end face of grinding thrust ball bearing.
Described grinding carriage can turn round adjustment around grinding carriage centre of gyration line.
Described swing friction tapered plane is supporting workpiece case and the workpiece box slip plane of moving guide rail in length and breadth, and when workpiece box drove workpiece around the reciprocal spherical track swing of oscillation center, swing friction tapered plane played the main support effect.
Dovetail groove below the described grinding wheel spindle can be adjusted grinding wheel spindle and do radial cutting and axially cutting, and promptly grinding wheel spindle can return and turn 90 degrees, and carries out the grinding of various part circular trace.
The utility model utilization swing frictional plane supports the spherical orbiting motion workpiece box of doing that can swing, and four limit dovetail ramp structures strengthen frictional plane, and frictional force strengthens.It is very big very big that this structure can be done the contact area of swing frictional plane, reaches in the φ 800 circle part scopes to process.
The workpiece that has needs processing ball-track is installed in not being in the mood on the jig of workpiece box, workpiece box can be along two orthogonal directions adjustment swings in horizontal plane, this principle is the adjustment that realizes by tetragonal dovetail groove, the both sides dovetail groove can be adjusted the size of the spherical motion track of swing workpiece box, and the both sides dovetail groove can be adjusted the axiality of main shaft and grinding wheel spindle in addition.The ball-type raceway center that guarantees workpiece overlaps with the oscillation center of lathe.Dovetail groove below the grinding wheel spindle can be adjusted grinding wheel spindle and do radial cutting and axially cutting, and promptly grinding wheel spindle can return and turn 90 degrees, and carries out the grinding of various part circular trace.
The emery wheel grinding tool is installed in the grinding wheel spindle front end of bistrique, bistrique drives the emery wheel grinding tool can hand feed on perpendicular to the grinding wheel spindle centerline direction, can be parallel to manually adjustment on the grinding wheel spindle centerline direction, whole grinding carriage can turn round adjustment around grinding carriage centre of gyration line.When carrying out the raceway groove grinding, driven by motor transmission device assurance workpiece is back and forth done spherical track swing around oscillation center.
Advantage of the present utility model is:
1, the circular arc of steel ball raceway groove is to generate by the swing of lathe is automatic, rather than crushing is become circular arc, forms by method of forming grinding, does not therefore need trimming wheel when grinding steel ball raceway groove, saves the time of a large amount of trimming wheels.Can raise the efficiency more than 3 times.
2, because the circular arc of steel ball raceway groove is to generate by the swing of lathe is automatic, the circularity precision height of circular arc is not subjected to the influence of abrasion of grinding wheel.
3, the utility model structure has solved the cantilever design defective of main shaft support workpiece box in the past, and it is little to have solved the Area of bearing of swinging the frictional plane cantilever design, supports unsettled shortcoming.
Description of drawings
Fig. 1 is the utility model structural representation sketch.
The specific embodiment
Reference numeral shown in Figure 1 is as follows: workpiece 1, workpiece box 2, be not in the mood for card 3, emery wheel 4, bistrique 5, grinding wheel spindle 6, grinding carriage 7, swing friction tapered plane 8.
The utility model by workpiece 1, workpiece box 2, be not in the mood for card 3, emery wheel 4, bistrique 5, grinding wheel spindle 6, grinding carriage 7, swing friction tapered plane 8 constitutes; Workpiece 1 is installed in not being in the mood on the card 3 of workpiece box 2, and swing friction tapered plane 8 is supporting workpiece case 2 and workpiece box 2 slip planes of moving guide rail in length and breadth, and emery wheel 4 is fixedly mounted on grinding wheel spindle 6 front ends of bistrique 5 by grinding carriage 7.
