Description
Technical field
The utility model relates to machining, chucking device field, specifically a kind of clamping device.
Background technology
When carrying out the machining of workpiece or measuring operation, after often needing first Workpiece clamping, fixing, then start operation, whether workpiece is clamped well or is fixing, will directly affect processing or the measurement effect of workpiece.At present, general conventional clamping structure has clamping clip, clamping platform, and clamping clip is simple in structure, relies on the grip of both hands by Workpiece clamping, and this has relatively high expectations to operating personnel's, needs to continue clamping clip to hold with a firm grip, has improved thus labour intensity.Clamping platform often adopts two clamps to realize Workpiece clamping, although compare clamping clip, clamp operation intensity is little, but the passing along with service time, clamping platform can send some ear-piercing noises, these noises are normally formed by the friction between clamp and operating desk, and such frictional noise not only affects operating environment, bring certain impact also to operating personnel's the sense of hearing.
Utility model content
The utility model provides a kind of clamping device, has solved current Workpiece clamping device and has easily produced noise, affects working environment, or even affects operating personnel's healthy problem.
The purpose of this utility model is achieved through the following technical solutions: a kind of clamping device, comprise two parallel guide rails, article two, one end of guide rail is fixed with quiet clamping plate, the other end connects by baffle plate, article two, between guide rail, be provided with the screw rod with guide rail parallel, described two guide rails are provided with moving clamping plate, the bottom of moving clamping plate is provided with drive block, drive block is provided with tapped through hole, screw rod is successively through quiet clamping plate, through hole, and be movably fixed on baffle plate, one end away from baffle plate on screw rod is provided with rotational structure, on described two guide rails, be also respectively provided with a guide groove, the below of moving clamping plate is provided with two guide wheels, two guide wheels are placed in respectively in two guide grooves.In this programme, the Main Function of baffle plate is movable standing screw, and screw rod can freely rotate, the effect of moving clamping plate and quiet clamping plate is by Workpiece clamping, the shape of moving clamping plate and quiet clamping plate does not have specific (special) requirements, those skilled in the art is also readily appreciated that and realizes, what the motion of moving clamping plate relied on is the rotation of screw rod, the effect of screw rod is similar to leading screw, clamping plate are moved back and forth along screw rod, and directly contact with guide rail for fear of moving clamping plate, the noise that reduces or even stop between moving clamping plate and guide rail to produce because of friction, this programme arranges guide groove on guide rail, under moving clamping plate, guide wheel is set, changed the sliding friction between moving clamping plate and guide rail into rolling friction thus, and in order further to stop noise, also lubricating oil can be splashed in guide groove.
Further, the two ends of described moving clamping plate are respectively provided with a clamp, and two guide rails are between two clamps, and the distance between two clamps equals the distance between the opposing opposite of two guide rails.Due to moving clamping plate, in motion process, just drive block is stressed, so stress point is relatively concentrated, is unfavorable for the stability of moving clamping plate, at moving clamping plate two ends, arrange after clamp, can by moving, clamping plate are whole to be stuck on guide rail, anti-stop clamping plate rock, and to obtain, preferably clamp effect.
Further, on the face that described quiet clamping plate are relative with moving clamping plate, be equipped with raised line.Raised line can strengthen the frictional force between workpiece and moving clamping plate, quiet clamping plate to a certain extent, prevents from occurring skidding in workpiece operation.
Further, the angle that described raised line becomes with vertical direction is 0 ~ 45 degree.Because moving clamping plate, quiet clamping plate and guide rail form a draw-in groove shape, in the time of operation, what workpiece was mainly subject to is the power of horizontal direction, therefore need not too much consider stressed on workpiece vertical direction, raised line, in vertical direction with 0 ~ miter angle, can guarantee that most frictional force can act in the horizontal direction.
Further, described rotational structure is one to be shaped as conical lever, and one end that this lever diameter is less is fixed on screw rod, and lever is perpendicular to screw rod.
Further, described rotational structure comprises an annulus and four support bars, and screw rod is through the center of circle of this annulus and perpendicular to the plane at this annulus place, one end of four support bars is all fixed on screw rod, the other end is all fixed on annulus, and four support bars are by the annulus quartering.The rotational structure of circular ring type can make the rotation of screw rod more comfortable, rotates more convenient.
Further, the part that described screw rod is positioned at two guide rails is provided with screw thread, and screw rod is positioned at two parts outside guide rail and is not provided with screw thread.Because the moving region of moving clamping plate is from start to finish in guide rail, so screw rod can only arrange part screw thread, and the part in guide rail arranges screw thread.
Further, described quiet clamping plate are provided with bearing, and screw rod is through this bearing.Under the effect of bearing, the friction meeting between screw rod and quiet clamping plate is relatively little, can further reduce the possibility that noise occurs.
The utlity model has following beneficial effect:
(1) the utility model adopts quiet clamping plate and moving clamping plate to clamp workpiece, the motion of moving clamping plate relies on the motion of screw rod to realize, meanwhile, below moving clamping plate, guide wheel is set, guide groove is set on guide rail, thereby avoided moving clamping plate to contact with the direct of guide rail, reduce the friction between moving clamping plate and guide rail, avoided the generation of noise, guaranteed good working environment, operating personnel are worked disturb little, environment is more comfortable.
(2) the utility model, by moving clamping plate two ends, clamp being set, will move clamping plate and be stuck on guide rail, increase the stress point of moving clamping plate, make workpiece more easily clamped, also can not produce and rock simultaneously.
(3) the utility model, by raised line being set on moving clamping plate and quiet clamping plate, has increased the friction between workpiece and quiet clamping plate, moving clamping plate, makes workpiece be difficult for skidding or even skid off quiet clamping plate and moving clamping plate in operation.
(4) the utility model adopts the rotational structure of circular ring type to realize the rotation of screw rod, thereby regulates better the position of moving clamping plate, and to realize the clamping of workpiece, bolt rotary is convenient, comfortable.
