Description
Technical field
The utility model belongs to a kind of machining set-up, is specifically related to a kind of clamping and positioning device of bar grinding attachment.
Background technology
Cylindricalo grinding for shaft-like workpiece generally is to use the clamping dop of the grinding machine headstock to clamp at an end of axle at present, the other end is located with the thimble centre bore, or the clamping dop clamping of an end usefulness grinding machine headstock, the other end or middle part are supported with second wheel, and the deficiency of this class clamping and positioning structure is:
1. because the workpiece that has does not allow other end band thimble center, so can't locate with centre bore.
2. adopt an end grinding machine headstock dop to clamp and add the other end or the support of middle part use second wheel, when carrying out grinding, emery wheel produces radial pressure to workpiece, make workpiece rely on second wheel, make axle obtain radial location, but workpiece little to diameter, the rigidity difference, emery wheel produces radial pressure to workpiece, it is crooked that workpiece is produced, and the support of second wheel is equivalent to a hinge fulcrum, and workpiece flexural deformation is bigger.In addition, because workpiece relies on second wheel, free unidirectional support produces the ground vibration in the time of can not eliminating the workpiece grinding, the workpiece grinding surface roughness is reduced.
Summary of the invention
The technical problems to be solved in the utility model overcomes above-mentioned deficiency, provides a kind of cylindricalo grinding operation to shaft-like workpiece easier, and the clamping and positioning device of the bar grinding attachment of a grinding accuracy that can improve spool and surface roughness.
The technical scheme that addresses the above problem is (referring to implementing illustration): the utility model is provided with workpiece and clamps dop (15) on the grinding machine headstock (16), spacing out with clamping dop (15), workpiece one side relative with emery wheel, being provided with can be to the upper roller (4) and the bottom roller (3) on the rolling wheel support (2) of being contained in of workpiece (5) radial location, it is characterized in that: at workpiece (5) opposite side relative with upper roller and bottom roller, be provided with the pinch rollers (6) that is installed in pinch rollers support (9) top, pinch rollers support (9) middle part articulates by swinging axle (7) and rolling wheel support (2), the spring (8) to its outside application of force is equipped with in the bottom, make pinch rollers (6) elasticity on top press to described upper roller and bottom roller, pinch rollers support (9) bottom with can be in transmission connection to its power part (11) that applies inside active force.
Operation principle of the present utility model is: the pinch rollers (6) elastic compression upper roller (4) and the bottom roller (3) under the effect of spring (8) that are contained in pinch rollers support (9) top, when needing to clamp shaft-like workpiece, workpiece one end is clamped on the clamping dop (15) of the headstock, apply and the rightabout power of spring (8) for pinch rollers support (9) bottom by power part (11), make the roller (6) that is contained in fastening spring support top break away from upper roller and bottom roller, the workpiece other end or its middle part are put into, between bottom roller and the pinch rollers, power part (11) discharges pinch rollers support bottom then, under the effect of spring (8), pinch rollers (6) elasticity clamping work pieces (5) can carry out grinding to excircle of workpiece then.
Shaft-like workpiece one end that the utility model will be processed clamps with the clamping dop of the grinding machine headstock, use three rollers to support the other end or middle part, when workpiece being carried out grinding with emery wheel, emery wheel produces radial pressure to workpiece, make workpiece rely on second wheel up and down, and pinch rollers is pressed to workpiece with spring, workpiece clamp in pinch rollers with up and down between the second wheel, is obtained the radial location of axle; The workpiece of, rigidity difference little to diameter, emery wheel are to the radial pressure that workpiece produces, and it is crooked that workpiece is produced, because three rollers have certain width that axially clamps, make its clamping be equivalent to a cantilever fulcrum, thereby can reduce the flexural deformation of workpiece, improve the grinding accuracy of workpiece workpiece.In addition, with three roller clip clamping of workpieces, the vibration that produces in the time of eliminating the workpiece grinding, the workpiece grinding surface roughness is improved.
The utlity model has advantage simple in structure, as to improve workpiece machining accuracy and surface roughness.
