Specific embodiment
Be described further below the technical solution of the utility model, but claimed range be not limited to it is described.
As shown in Figure 1, Figure 2, Figure 3, Figure 4, the utility model provides a kind of for processing the fixture of long drill steel, including bearing
Body 1 and multiple clamping devices 2, clamping device 2 include that U-shaped support 4, the first anchor ear 5 and the second anchor ear 6, support 4 are installed on bearing
On the approximately the same plane of body 1, the first anchor ear 5 is fixedly installed on support 4, and U-shaped support 4 has first support arm 401 and second
Support arm 402, one end of the second anchor ear 6 and first support arm 401 are hinged, when the other end of the second anchor ear 6 is connect with second support arm 402
When together, the first anchor ear 5 and the second anchor ear 6 two faces relative to each other around formed both ends be connected to, the clamping of all round closure
Curved surface 506 clamps and is equipped with several rolling bearings 7 on curved surface 506.
Using the technical solution of the utility model, clamping workpiece is compressed it within curved surface by rolling bearing in clamping,
Rolling bearing outer peripheral surface is in contact with workpiece surface, and for axially parallel line contacts with workpiece, this makes for the part that contacts with each other
Bearing weighs influence minimum wounded for workpiece surface, and the clamp for machining of the utility model is made both to be applicable to workpiece rotation, cutter
It in opposing stationary cutting processing system, is equally applicable to that workpiece is opposing stationary, in the cutting processing system of cutter rotation, clamps
Axially arrangement is multiple along workpiece for device, keeps workpiece position stress each in the axial direction more balanced, workpiece has been effectively ensured and has added
The technical indicators such as concentricity and straightness during work, and since rolling bearing is along workpiece radial direction application active force, appoint
Meaning two rolling bearings relative to each other towards each other apply radial clamping force on the surface of the workpiece, offset each other,
Reduce the damage to workpiece surface, and rolling bearing is contacted with workpiece surface for line, it means that workpiece is firstly the need of overcoming
The case where frictional force that line contact generates can slide axially, the size of the frictional force are generally radial clamping force rather
One of, therefore, the utility model is clearly advantageous to prevent workpiece from axially sliding.
Further, rolling bearing 7 is deep groove ball bearing.Clamp the appearance profile and 3 cross-sectional profile of workpiece of curved surface 506
Unanimously.Further, the quantity of rolling bearing 7 is 4, is respectively rotation center by circle using the central axis for clamping curved surface 506
All arrays are evenly arranged.Clamp the appearance profile of curved surface 506 both can with when it is round, be also possible to polygon, preferably number of edges is
