The utility model has the advantages of simple structure, be convenient for install. The utility model discloses a bar is put up to the centre frame main part, therefore the charge bar can obtain fine processing rigidity, can not be because of the bar overlength, cause the course of working in the bar crooked, and influence the machining precision, the oval -shaped condition can not appear.
Description
Technical field
This utility model is related to clamping structure technical field, refers in particular to a kind of control lathe center frame.
Background technology
When needing to process long-axle workpieces, one end of workpiece is fixed by traditional installation way just with workbench,
Because the draw ratio of these workpiece is big, in long tubular, and workpiece height is high, in processing, the easy whipping of the other end of workpiece, and work
Part is easily subject to the effect of radial cutting force to produce flexural deformation.Meanwhile, the whipping of workpiece one end easily causes the vibrations of cutter, damages
Cutter, affects processing progress, reduces production efficiency.Traditional traditional numeric-control lathe adds, for elongated workpieces, the side that formula is with thimble
Formula is completing, but thimble processing can make part stress bend to the power of thimble and cutter.In addition, thimble can interfere lathe tool and
Do not process the end face of part.
Utility model content
This utility model is directed to problem of the prior art and provides a kind of control lathe center frame.
In order to solve above-mentioned technical problem, this utility model adopts the following technical scheme that：
A kind of control lathe center frame, includes reverse V-shaped steady rest body, and the two ends of steady rest body are used for installing admittedly
Fixed, the middle turning point of described steady rest body is the central circular being provided with round tube hole, runs through and be provided with described central circular
For clamping the clamping head of charge bar, one end of described clamping head is provided with threaded connector, is provided with and will press from both sides on threaded connector
The locking nut that tight head is strained to side.
Wherein, cylindrical bearing is set between described clamping head and round tube hole, and described cylindrical bearing is sheathed in clamping head, and
The same side of locking nut is provided with bearing lock nut.
Further, described cylindrical bearing includes bearing outer ring, some cylindrical rollers and bearing neck bush, in described bearing
The side of bushing is extended threaded section, and described bearing lock nut is connected with threaded section, in bearing neck bush
Opposite side be extended restraining position ring block, described threaded section, spacing ring and bearing neck bush are integrally formed.
Wherein, the both ends of described steady rest body are fixedly installed connecting seat respectively, described connecting seat are provided with many
Individual bolt hole.
The beneficial effects of the utility model：
A kind of control lathe center frame that this utility model provides, its structure is simple, is easily installed.Described steady rest body
Bar is supported, therefore charge bar can obtain good processing rigidity, will not be long because of bar, causes rod in the course of processing
Material bending, and affect machining accuracy, be not in oval situation.
