Abstract
The utility model relates to an adjustable core clamper of digital control lathe tail-holder which belongs to digital control lathe field. It is composed of tail-holder sleeve and core clamper. Internal cylindrical surface in tail-holder sleeve is installed with one adjustment sleeve through screw same axis engagement. The adjustment sleeve same axis processing has one taper hole matching with installation conical surface of core clamper. The utility model has realized the adjustability of tail-holder core clamper, solved the problem of workpiece deformation due to unchanged top force of tail-holder core clamper and effectively improved the processing accuracy of workpiece. It is particularly suitable for digital control lathe processing of parts with bad structural rigidity and that can deform easily.
Description
Technical field
The utility model belongs to the Digit Control Machine Tool field, and especially a kind of Digit Control Machine Tool tailstock is adjustable top.
Background technology
At present, the tailstock of Digit Control Machine Tool adopts hydraulic-driven or pneumatic, and the tight surely power of adjustable minimum is bigger, and the workpiece on turn does not hold out against feel.Like this, in process, can produce certain deformation, thereby influence the machining accuracy of workpiece for poor, the yielding part of some rigidities of structure.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, thereby provides the Digit Control Machine Tool tailstock of the top power size that a kind of physical location of adjusting tailstock centre adjusts tailstock centre adjustable top.
The utility model solves its technical problem and takes following technical scheme to realize:
This Digit Control Machine Tool tailstock is adjustable top, by barrel of tail stock, toply constitute, it is characterized in that: be equipped with one at the barrel of tail stock inner cylinder face by the coaxial engagement of screw thread and adjust sleeve, the coaxial processing of this adjustment sleeve is shaped on a taper hole that can match with the top installation conical surface.
And, but the end of described adjustment sleeve is equipped with a thread lock barrel of tail stock and the locknut of adjusting sleeve by screw-threaded engagement.
Advantage of the present utility model and beneficial effect are:
By the adjustment sleeve that coaxial threaded in barrel of tail stock is installed, can adjust the axial displacement of sleeve by threaded adjustment, and then adjust top axial displacement, and adopt locknut to give lock in place.So just realized the adjustable of tailstock centre, the top power that has solved tailstock centre immobilizes and may cause the problem of workpiece deformation, has improved the machining accuracy of workpiece effectively, is particularly useful for that the rigidity of structure is poor, the processing of the Digit Control Machine Tool of yielding part.
Description of drawings
Fig. 1 is a cross section of the present utility model sectional structure chart.
The specific embodiment
Below in conjunction with accompanying drawing the utility model embodiment is further described:
Digit Control Machine Tool tailstock described in the utility model is adjustable top, is that the face of cylinder made in barrel of tail stock 2 is equipped with an adjustment sleeve 3 by screw thread 1 coaxial engagement, can adjust barrel of tail stock and the axial displacement of adjusting sleeve by the rotation barrel of tail stock like this.But the end at this adjustment sleeve is equipped with a thread lock barrel of tail stock and the locknut 5 of adjusting sleeve by screw-threaded engagement, and this locknut promptly adopts this locknut lock in place after barrel of tail stock and the adjustment of adjustment sleeve are located.Be shaped on a taper hole that can match in the coaxial processing of adjustment sleeve with the top installation conical surface 4.
Claims (2)
1. a Digit Control Machine Tool tailstock is adjustable top, by barrel of tail stock, toply constitute, it is characterized in that: be equipped with one at the barrel of tail stock inner cylinder face by the coaxial engagement of screw thread and adjust sleeve, the coaxial processing of this adjustment sleeve is shaped on a taper hole that can match with the top installation conical surface.
2. Digit Control Machine Tool tailstock according to claim 1 is adjustable top, it is characterized in that: but the end of described adjustment sleeve is equipped with a thread lock barrel of tail stock and the locknut of adjusting sleeve by screw-threaded engagement.
