Abstract
The utility model discloses a workpiece shaft for a grinding machine. The workpiece shaft comprises a workpiece shaft body, a belt pulley, a bearing, a flexible sleeve, a positioning shaft, a clutch seat, a one-way clutch and a workpiece, wherein the workpiece shaft body is fixedly arranged on a mounting seat and sleeved in an inner hole of the bearing; the excircle of the workpiece shaft body is arranged in the belt pulley; an end cover is fixed on the belt pulley and pressed by the bearing; the clutch seat is connected with the end cover through the flexible sleeve; the belt pulley directly drives the one-way clutch to rotate; and the workpiece is grasped by the one-way clutch. The workpiece shaft has the advantages that the workpiece shaft body is fixed, and the belt pulley rotates, so that the requirement on the machining accuracy of the workpiece shaft body is met; and meanwhile, a point-to-surface contact mode is adopted, and a steel ball is welded at the front end of the positioning shaft, so that the influence of the end surface accuracy of the workpiece on the rotary motion of the workpiece is reduced.
Description
Technical field:
The utility model relates to a kind of grinding machine workpiece spindle, is specially adapted to install on the water pump shaft bearing grinding machine.
Background technology:
Existing is the sketch map of raw water pump axle bearing grinding machine workpiece spindle structure like Fig. 1; It is mainly by workpiece spindle 1, workpiece housing 4, belt pulley 2, bearing 3, stage clip 5, spring base 6, and assemblies such as bolt 7, flexible boot 8, locating shaft 9, clutch base 10, one-way clutch 11 are formed.Workpiece spindle 1 is formed the supporting of group angular contact bearing by two, is contained in the workpiece housing 4, applies pretightning force through 5 pairs of bearings of the stage clip in the spring base 6.Bolt 7 positions of fixing spring seat 6 in the workpiece housing, thereby the axial location of location workpiece spindle in the workpiece housing.The workpiece spindle rear end wheel that thongs, the round nut back of the body is tight, flat key is circumferentially located; Front end dress flexible boot, pipe collar locking.Locating shaft is contained in the screwed hole of workpiece spindle front end.One-way clutch is contained in the clutch base, is used for promptly workpiece, and rotates with flexible boot.When motor drove the belt rotation through belt, belt pulley drive workpiece spindle and the flexible boot, clutch base, the one-way clutch that are fixed on the workpiece spindle rotated together.One-way clutch is firmly grasped workpiece, realizes the gyration of workpiece.Its movement characteristic is the gyration that is realized workpiece by the rotation of workpiece spindle.Its shortcoming is the gyration that the running accuracy of workpiece spindle can directly influence workpiece.Therefore this structure is higher to the requirement on machining accuracy of workpiece spindle.
Summary of the invention:
The task of the utility model is to propose a kind of influence of eliminating workpiece spindle to workpiece; Reduced requirement to the workpiece spindle machining accuracy; The task of the utility model is done in such a way that it comprises workpiece spindle, belt pulley, bearing, flexible boot, locating shaft, clutch base, one-way clutch and workpiece; It is characterized in that: be fixed with the workpiece spindle workpiece spindle on the mount pad and be sleeved in the brearing bore; Its cylindrical is contained in the belt pulley, and end cap is fixed on the belt pulley and with bearing and compresses, and clutch links to each other with end cap through flexible boot.Described belt pulley directly drives the one-way clutch rotation, and described workpiece promptly is to be firmly grasped by one-way clutch.The utlity model has following effect: the utility model is to adopt workpiece spindle fixed; Realize the requirement on machining accuracy of workpiece spindle by the belt pulley rotation; Simultaneously; Adopt the way of contact of some face, be welded with a steel ball at the locating shaft front end, thereby reduced of the influence of workpiece end face precision workpiece rotational motion.
Description of drawings:
Fig. 1 is the structural representation of existing workpiece spindle; Fig. 2 is the structural representation of the utility model.
Drawing explanation: 1, workpiece spindle, 2, belt pulley, 3, bearing, 4, the workpiece housing, 5, stage clip; 6, spring base, 7, bolt, 8, flexible boot, 9, locating shaft, 10, clutch base; 11, one-way clutch, 12, workpiece, 13, mount pad, 14, bucker, 15, end cap.
The specific embodiment:
Describe embodiment in detail in conjunction with above accompanying drawing, be fixed with workpiece spindle 1 on the mount pad 13, workpiece spindle is sleeved in the dead eye; Bucker 14 is equipped with in workpiece spindle outside, and its cylindrical is contained in belt pulley 2 inner ends lid 15 and is fixed on the belt pulley, and compresses clutch 10 with bearing and link to each other with end cap 15 through flexible boot 8; Locating shaft 9 is contained in the workpiece spindle 1 front end screwed hole; One-way clutch 11 is contained in 10 li of clutch bases, and firmly grasps workpiece, when motor drives the belt pulley rotation through belt; Belt pulley drives coupled end cap, flexible boot, clutch base, one-way clutch and rotates together; One-way clutch is firmly grasped the gyration that workpiece is realized workpiece 12, has realized that workpiece spindle is motionless directly to drive the one-way clutch rotation by belt pulley, thereby has eliminated the influence of workpiece spindle to workpiece.
Claims (2)
1. grinding machine workpiece spindle; It comprises workpiece spindle, belt pulley, bearing, flexible boot; Locating shaft, clutch base, one-way clutch and workpiece is characterized in that: be fixed with the workpiece spindle workpiece spindle on the mount pad and be sleeved in the brearing bore, its cylindrical is contained in the belt pulley; End cap is fixed on the belt pulley and with bearing and compresses, and clutch links to each other with end cap through flexible boot.
2. a kind of grinding machine workpiece spindle according to claim 1 is characterized in that: described belt pulley directly drives the one-way clutch rotation, and described workpiece promptly is to be firmly grasped by one-way clutch.
