Description
Technical field
This utility model relates to a kind of mechanical transmission clamping device, specifically, is a kind of grinder center frame suitable in thin and long shafts part.
Background technology
In grinding operation, having a kind of thin and long shafts part, the draw ratio of this kind of part is very big sometimes, reaches more than 50, and diameter is not as again big sometimes, such as about 20mm or less.This kind of part, without step or other groove etc., is typically all employing centerless grinding processing；But, sometimes such slender axles part cannot adopt centreless grinding to process because of requirements such as structures, and it being also performed to grinding in center, this is highly difficult when having resulted in existing cylindrical grinder and auxiliary grinding, it is easy to causes and beats and consequence that size is unstable.Because slender axles are on cylindrical grinder during grinding, with the two ends centre bore of the top top tight workpiece at two ends, owing to the rigidity of slender axles is very poor, top when slightly holding out against axle will bend, or when middle part grinding, cutter relieving vibrations etc. occur.During the centre frame worn with existing grinding machine, often neither be highly desirable, because workpiece only two fulcrums on centre frame, do not push down when workpiece upwards shakes, so being always not sufficiently stable during grinding.
Summary of the invention
The purpose of this utility model is in that to provide a kind of clamping dynamics good, the grinder center frame of simple in construction.
This utility model is realized by following technological means: a kind of cylindrical grinder centre frame, including main body, in the side of main body, the second bearing is set, main body on the downside of the second bearing arranges extension, described extension arranges the 3rd bearing, the top of main body connects paw by rotating axle, arranges clutch shaft bearing on paw top, and described clutch shaft bearing, the 3rd bearing can move along Y direction, the second bearing can move along X-direction.
Also include handle, described handle includes first handle, second handle, the 3rd handle, described first, second, third handle is connected with first, second, third bearing respectively, described handle connects screw rod, screw rod arranges external screw thread, described first, second, third bearing is arranged and the equal-sized through hole of outer screw diameter, female thread is set in through hole.
Also setting up movable supporting frame at body top, movable supporting frame is arranged far from the side of paw, arranges the groove that can support first handle screw rod at movable supporting frame top.
Described second handle and the 3rd handle are arranged on the main body side away from the second bearing and the 3rd bearing, and handle is connected with bearing by described screw rod through main body.
It is arranged below wheel in main body.
Compared with prior art, fulcrum quantity has been become 3 from 2 to this utility model by it, greatly strengthen the clamping dynamics to part, and does not become complicated in structure, and production cost can control.

Detailed description of the invention
Below in conjunction with Figure of description, this utility model is described in further detail:
This utility model relates to a kind of clamping device, specifically, is a kind of grinder center frame suitable in thin and long shafts part, it includes a main body, and main body is box-structure, and the bottom of main body is provided with wheel, it is preferably universal wheel, so just can carry out clamping device easily and move.Side in main body, it is provided with the second bearing, in main body on the downside of second bearing, one extension is set, extension tip arranges the 3rd bearing, top in main body, arranging a paw, paw is connected in main body by the first straight pin 7, and is freely rotatable, paw foremost on be provided with clutch shaft bearing, three bearings are all removable, and wherein the first, the 3rd bearing can move along Y direction, and the second bearing can move along X-direction, by cooperating of three bearings, part is effectively clamped.
In this utility model, the handle that is moved through of bearing completes, accordingly, handle is divided into first handle, second handle and the 3rd handle, and correspondence controls clutch shaft bearing, the second bearing and the 3rd bearing respectively, and described handle connects a screw rod, bearing is respectively provided with the through hole that internal diameter is identical with outer screw diameter, along with the rotation of handle, bearing moves, and reaches to change the effect of position.
In this utility model, the screw rod of second handle and the 3rd handle is arranged at body interior, and the screw rod of first handle is exposed, therefore at the top of this utility model main body, also having a moveable support, movable supporting frame is arranged far from the side of paw, arranges the groove that can support first handle left-handed screw 5 at movable supporting frame top, so when first handle works, will not fracture because of unbalance stress.
In this utility model, described paw 8 is connected by the second straight pin 6 with left-handed screw 5, and so, screw rod just can be folded, thus making device overall structure more compact.
In this utility model, three handles are respectively provided with locking device, thus ensure that the stability when holding parts.
Illustrate below by an example:
First first handle 4 is reversed and on lift drive paw 8 turn over to releasing orientation, start feeding, workpiece on grinding machine with the top centre bore holding out against two ends in two ends, degree of tightness is suitable, then second handle 1 and the 3rd handle 2 are rotated, the second bearing 12 and the 3rd bearing 11 is made just to contact with workpiece 10, then second, third handle locked, operation first handle 4 overturns paw 8 and is at duty, and rotate forward first handle 4 and make clutch shaft bearing 9 workpiece pressing 10, namely complete the clamping of workpiece, grinding can be carried out with that.
