Abstract
The invention discloses a kind of novel hydraulic tailstock core shaft structure, including tailstock body, tailstock oil cylinder, cylinder flange, mandrel flange, piston attaching nut, guide pin bushing, back-up ring, scraping article, center sleeve, top, T-shaped piece, ruler for reading, proximity switch support, proximity switch, mandrel and bolt.Novel hydraulic tailstock core shaft structure of the invention is simpler than the structure of conventional tailstock mandrel, requirements to parts substantially reduce, and reduces processing cost；Installation is more convenient simultaneously, automaticity is also higher, stroke is fully controllable.
Description
Technical field
The invention belongs to numerical-control horizontal lathe field, and in particular to a kind of novel hydraulic tailstock core shaft structure, for tailstock
Movement, the control of mandrel.
Background technology
The hydraulic tailstock generally use of today's numerical control lathe is embedded or integrated pushing formula.Embedded, mandrel cylinder integrates
To tailstock, mechanism is complicated, and parts require high, cumbersome for installation.And without position record, control；Monoblock type driving
Tailstock, it is to the requirement of tailstock bottom space big, do not apply to that (tailstock stroke is big, the liquid of bottom integrated pushing with the lathe of big stroke
Cylinder pressure is oversize, can not arrange).
The content of the invention
Goal of the invention：In order to solve the deficiencies in the prior art, the invention provides a kind of novel hydraulic tailstock core shaft structure.
The purpose of this patent is to make that the structure of tailstock mandrel is simpler, installation is more convenient and accomplishes that mandrel stroke is controllable, cost is lower.
Technical scheme：A kind of novel hydraulic tailstock core shaft structure, including tailstock body, tailstock oil cylinder, cylinder flange, mandrel
Flange, piston attaching nut, guide pin bushing, back-up ring, scraping article, center sleeve, top, T-shaped piece, ruler for reading, proximity switch support, close to opening
Pass, mandrel and bolt；
Guide pin bushing is installed with the tailstock body, the guide pin bushing is built with mandrel；
The head of the mandrel is installed with center sleeve, has in the center sleeve top；
The afterbody of the mandrel is installed with tailstock oil cylinder, and cylinder flange and core are cased with order on the tailstock oil cylinder
Shaft flange, piston attaching nut is screwed on oil cylinder piston, mandrel flange is locked on mandrel, last locking cylinder flange；
Described T-shaped piece is arranged on mandrel by bolt, and ruler for reading is arranged on T-shaped piece above, and proximity switch support is consolidated
It is scheduled on tailstock body, 3 proximity switches are arranged on proximity switch support.
As optimization：The head of the mandrel and it is top between be lined with back-up ring.
As optimization：The head of the mandrel and it is top between scraping article is installed.
Beneficial effect：The present invention novel hydraulic tailstock core shaft structure it is simpler than the structure of conventional tailstock mandrel, to zero
The requirement of part substantially reduces, and reduces processing cost；Installation is more convenient simultaneously, automaticity is also higher, stroke is fully controllable.
The present invention reaches the purpose that tail stock held out against, loosened workpiece by mandrel side-to-side movement；Pass through in simultaneously mobile
Three proximity switches sense the signal intensity for counting chi, and the purpose (core of control tailstock mandrel position is being reached by PLC logics
Controllableization that axle advances, retreats, stopped).
