Description
Technical field
The present invention relates to lathe tailstock holder structure technical field, more particularly to a kind of for hydraulic tailstock Discrete control
Guide frame.
Background technology
Numerically controlled lathe tailstock is one important part of lathe, generally uses hydraulic tailstock form, tailstock body at present
On bed body guide rail, and it can be moved along Z-direction, move mode is usually manually or lathe drags.
Reach after specified location manually hand or with hydraulic mechanism by platen clamp.The hydraulic pressure of tailstock itself is utilized every time
The flexible of sleeve mechanism holds out against or unclamps workpiece.In order to improve efficiency, the stroke of sleeve is generally limited, in sleeve both sides
Have two travel switches and be used for control sleeve stroke.Typically by Stroke Control within 30-50mm.
The hydraulic tailstock of above-mentioned this structure when change processing part need to move tailstock when operate it is cumbersome, first will pine
Drive tailstock pressing plate, then move, in place after clamp again.This process can produce certain influence to tailstock precision.It is whole dynamic
If work is bigger using manually-operated mode labor intensity, be not suitable for the occasion frequently with changing part.If using machine
Bed dragging and Automatic-clamping unclamp mode then need to increase set of device in addition to realize, control it is more complicated, fault rate compared with
It is high, it is often necessary to human intervention.For telescopic barrel of tail stock, it should ensure that centering precision ensures good slip again
Property, mode of the generally use with boring or honing process tailstock body sleeve hole, and processing cost is higher, and with after a while
Producing abrasion causes gap excessive.Need to readjust or change.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of guide frame for hydraulic tailstock Discrete control, will pass
Tailstock cylinder in system structure is stretched out and an action is merged into tailstock body movement, is all completed by the hydraulic jack of lower section, significantly simple
Changed the structure of whole tailstock component, improved reliability, using switch and buting iron realize two kinds of shift motions of tailstock body it
Between conversion, programming Control can be realized to whole tailstock component, more than 50% can be reduced compared with traditional structure cost, efficiency can
1 times is improved so that hydraulic jack is hidden in below protective cover, and whole workspace does not have hydraulic line, advantageously in the row of iron filings
Go out.
The technical solution adopted for the present invention to solve the technical problems is：There is provided a kind of for hydraulic tailstock Discrete control
Guide frame, including lathe bed, tailstock body and oil cylinder, described lathe bed top are disposed with one of rail groove, and left and right is moved in rail groove
It is dynamic that tailstock body is installed, connecting seat is installed on rail groove one end, oil cylinder is installed on the rail groove other end, rail groove middle part is horizontal
To several stroke buting iron are uniformly provided with, described tailstock body lower end is provided with switch adjustment knot corresponding with stroke buting iron
Structure, described switch adjustment structure include adjustment plate mounting seat and adjustment plate, and described tailstock body lower disposed has to be extended down
Adjustment plate mounting seat, be installed with the adjustment plate moved left and right, described adjustment plate on front side of described adjustment plate mounting seat
Lower end extend into the top of stroke buting iron, the lower end of described adjustment plate is vertically symmetrical to be provided with the first travel switch and second
Travel switch.
Described the first travel switch and the second travel switch is connected by the fixed plate of lateral arrangement with adjustment plate.
A word through hole is disposed with described adjustment plate, is provided with a described word through hole through adjustment plate with adjusting
The connected lock-screw of whole plate mounting seat.
Described adjustment plate upper end is provided with the briquetting being connected by screw with adjustment plate mounting seat, described briquetting downside
Wrap up the upper end of adjustment plate.
Adjustment handle is installed on front side of described adjustment plate.
The embedded guide pad for being provided with rear side and being bonded on front side of adjustment plate mounting seat on rear side of described adjustment plate upper end.
Tailstock is carried out first to zero, first by tailstock body clear point, now the first travel switch and the second travel switch are same
When send signal, be defined as tailstock body zero point, tailstock be then moved to the left by suitable distance according to Workpiece length, is moved to the left
When the second travel switch is shielded, only allow first travel switch to signal, often send out signal instruction tailstock body and move two
The distance at stroke buting iron interval, in place after, release the second travel switch shielding；
Afterwards by button control oil cylinder, input hydraulic pressure, tailstock body is promoted so that the thimble workpiece pressing on tailstock body,
When lathe produces pressure feedback, illustrate that workpiece has been held out against；
When then carrying out Operation switch adjustment structure, lock-screw is unclamped, left and right is carried out to adjustment plate by adjusting handle
It is mobile so that the first travel switch and the second travel switch are in stroke buting iron both sides or between two stroke buting iron,
Ensure that the first travel switch and the second travel switch will not produce signal, now workpiece is in and holds out against state；
Then be processed, control tailstock body to move backward by oil cylinder after machining, until the first travel switch or
Second travel switch aligns with stroke buting iron send signal after stop, now workpiece is in releasing orientation, can carry out workpiece more
Change, control tailstock body court to move left after replacing again so that workpiece pre-tightening, to operate by identical, enter to same batch work-piece
Row processing；
Need to perform again when changing different batches workpiece and performed since first step step.
When adjustment plate is adjusted, it is ensured that adjustment plate moves toward near the stroke buting iron direction of itself.
Beneficial effect：It is compact-sized the present invention relates to a kind of guide frame for hydraulic tailstock Discrete control, have with
Lower advantage：(1) the tailstock cylinder on traditional structure is stretched out and an action is merged into tailstock body movement, all by the hydraulic oil of lower section
Cylinder is completed；(2) structure of whole tailstock component is enormously simplify, improves reliability；(3) tail is realized using switch and buting iron
Conversion between two kinds of shift motions of pedestal；(4) programming Control can be realized to whole tailstock component, can compared with traditional structure cost
To reduce by more than 50%, efficiency can improve more than 1 times；(5) hydraulic jack is hidden in below protective cover, and whole workspace does not have liquid
Pressure pipeline, advantageously in the discharge of iron filings.
