Abstract
The invention discloses a thin wall workpiece centering clamp spindle which comprises a support, wherein a nut is fixed on the support, a shaft lever is in threaded fit into the nut, threads matched with the nut are formed in one end of the shaft lever, a handle for rotating the shaft lever is arranged at the other end of the shaft lever, a baffle is arranged in the middle of the shaft lever, a support ring, a corrugated sleeve and a retainer ring are arranged between the baffle and the nut sequentially, and the retainer ring is in contact with the nut. The shaft lever is driven to rotate together by rotating the handle. One end of the shaft lever is in threaded insertion into the nut fixed on the support, so that the shaft lever moves axially in the rotation process. When a workpiece is required to be clamped, the shaft lever is driven to move to the nut, the baffle located on the shaft lever extrudes the support ring, the support ring extrudes the corrugated sleeve between the support ring and the retainer ring so that the corrugated sleeve compresses, the compressed corrugated sleeve expands uniformly axially, and the thin wall workpiece is centered and clamped form inside to outside.
Description
Technical field
The present invention relates to a kind of clamping tool for machine work, be specifically related to a kind of thin-wall workpiece centering clamping axle.
Background technology
Axle, being used for support rotary workpiece only bears moment of flexure and not transmitting torque, and some central axis, as the axle etc. of rolling stock, some axle is not then rotated, as the axle etc. of supporting pulley.Whether rotate when working according to axle, axle can be divided into mandrel and stationary spindle again.Its central shaft: only bear moment of flexure and not transmitting torque; Rotating shaft had not only born moment of flexure but also transmitting torque; A power transmission shaft transmitting torque and do not bear moment of flexure, or moment of flexure is very little.Processing thin-walled workpiece particularly thin-wall pipe time, due to the limited strength of workpiece itself, can not clamp from outside, the damage of workpiece can be caused from outside clamping.Consider and can not clamp from outside, elastic expansion-sleeve can only be adopted to clamp from inside.But elastic expansion-sleeve is generally use metal manufacture, when carrying out inside clamping to workpiece, very easily scratch or defective work piece, cause the processing of workpiece not meet the requirement of use.
Summary of the invention
The object of the present invention is to provide a kind of thin-wall workpiece feel relieved clamping axle, can clamp thin-wall workpiece by structural adjustment and fix, and can not clamp process in defective work piece.
For achieving the above object, technical scheme of the present invention is: thin-wall workpiece centering clamping axle, comprise bearing, described bearing is fixed with a nut, in described nut, threaded engagement has axostylus axostyle, and one end of described axostylus axostyle is provided with the screw thread with nut screw connection, the other end of described axostylus axostyle is provided with the handle of rotating shaft rod, the middle part of described axostylus axostyle is provided with a baffle plate, and be provided with bracing ring, radiation fins and back-up ring successively between described baffle plate and nut, described back-up ring contacts with nut.
When adopting technique scheme, by turning handle, axostylus axostyle is driven to rotate in the lump.One end due to axostylus axostyle is that screw thread inserts in the nut be fixed on bearing, causes axostylus axostyle to move axially in the process of rotating.When needs clamping work pieces, drive shaft rod moves to nut, is positioned at the baffle plate extruding bracing ring on axostylus axostyle, radiation fins between back-up ring is extruded by bracing ring, radiation fins is compressed, radiation fins radial dilatation equably after compression, thin-wall workpiece is felt relieved and from inside to outside clamps.Structure of the present invention is simple, can clamp thin-wall workpiece and fix, and can not in the process clamped defective work piece.
Further, described radiation fins is at least provided with the clamping ring of two-layer projection.This setting can increase the contact area of radiation fins and workpiece, reduces local pressure further, prevents workpiece deformation.
Further, described baffle plate is circular, and the external diameter of described baffle plate is identical with the external diameter of bracing ring.This setting can be convenient to processing and use.
Further, on described radiation fins, the cross sectional shape of clamping ring is trapezoidal.Trapezoidal cross section makes the contact of radiation fins and sheet workpiece be that face contacts, and increases contact area.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Fig. 1 is the structural representation of thin-wall workpiece of the present invention centering clamping axle embodiment.
Detailed description of the invention
As shown in Figure 1, thin-wall workpiece centering clamping axle of the present invention, comprise bearing, bearing is fixed with a nut 1, in nut 1, threaded engagement has axostylus axostyle 2, and one end of axostylus axostyle 2 is provided with the screw thread with nut screw connection; The other end of axostylus axostyle 2 is provided with the handle 3 of rotating shaft rod, and the middle part of axostylus axostyle 2 is provided with a baffle plate 4, and be provided with bracing ring 5, radiation fins 6 and back-up ring 7 between baffle plate 4 and nut 1 successively, back-up ring 7 contacts with nut 1.Baffle plate 4 is circular, and the external diameter of baffle plate 4 is identical with the external diameter of bracing ring 5.This setting can be convenient to processing and use.Radiation fins 6 is provided with the clamping ring of two-layer projection, and on radiation fins 6, the cross sectional shape of clamping ring is trapezoidal.Trapezoidal cross section makes the contact of radiation fins and sheet workpiece be that face contacts, and increases contact area, reduces local pressure further, prevent workpiece 8 to be out of shape.
When adopting technique scheme, by turning handle 3, axostylus axostyle 2 is driven to rotate in the lump.One end due to axostylus axostyle 2 is that screw thread inserts in the nut 1 be fixed on bearing, causes axostylus axostyle 2 to move axially in the process of rotating.When needs clamping work pieces 8, drive shaft rod 2 moves to nut 1, the baffle plate 4 be positioned on axostylus axostyle 2 extrudes bracing ring 5, radiation fins 6 between back-up ring 7 is extruded by bracing ring 5, radiation fins 6 is compressed, radiation fins 6 radial dilatation equably after compression, feels relieved workpiece 8 and from inside to outside clamps.Structure of the present invention is simple, can clamp workpiece 8 and fix, and can not in the process clamped defective work piece 8.
Above-described is only the preferred embodiment of the present invention; should be understood that; for a person skilled in the art; without departing from the inventive concept of the premise; some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.
