Description
Technical field
The present invention relates to Metal Cutting Machine Tool field, particularly relate to a kind of band self-centering chuck processing revolution class workpiece
Single-column high-speed numeric control vertical vehicle turning equipment.
Background technology
At present, the speed of mainshaft of common vertical lathe is relatively low, and when processing small-sized revolution class workpiece, efficiency is low, and cannot reach
To required surface roughness equally accurate requirement, can produce due to reasons in structure own when common vertical lathe runs to high speed
Vibration, it is impossible to ensure the precision of processing.Existing high-speed vertical lathe is connected directly to by belt pulley or other modes by motor
The main shaft of vertical lathe, chuck for installing on main shaft, main shaft drive card disc spins.The master when chuck is in long-time high speed rotating
Axle easily generates heat, thus causes machining accuracy to reduce；And when chuck low speed rotation, owing to output torque is not enough, lathe cannot
Carry out normal machining.When vertical lathe is used for processing revolution class workpiece, during roughing, gripper chuck clamping of workpieces needs bigger
Clamping force；When polish, in order to prevent workpiece from deforming, need the suitable clamping force reducing chuck, therefore work as roughing
After need to manually adjust the clamping force of chuck, then carry out the polish to workpiece.
Summary of the invention
The purpose of the present invention is to propose to the single-column high-speed numerical-control vertical lathe of a kind of band self-centering chuck, this vertical lathe
Main shaft can guarantee that output torque when low-speed running, and main shaft can keep stablizing of processing when running up, and this lathe can also
Realize the self-centering of workpiece during Workpiece clamping, and by numerical control program, the clamping force size of chuck can be adjusted.
For achieving the above object, this equipment is mainly by base, chuck, inner carrier, outer piston, knife bar, electric knives tower, basis
Body, crossbeam, column, longitudinal electric machine, traverse motor, bascule, operating board, main shaft, driven pulley, oil cylinder, main motor,
Multi-speed gear box, drivewheel, hydraulic system etc. form.The parts such as column, column entablature, body are installed, by vertical on base
Drive body and electric knives tower to do and longitudinally, laterally move to motor, traverse motor, thus realize electric knives tower longitudinal,
Traverse feed.Main motor is arranged on multi-speed gear box, and belt pulley installed by multi-speed gear box outfan.Come by belt transmission
Drive installation main shaft on base, by electrical system the control of main motor realized to chuck velocity of rotation stepless
Speed governing, ensures enough output torques by the gearshift of HYDRAULIC CONTROL SYSTEM multi-speed gear box.Hydraulic jack is installed in main shaft bottom,
Hydraulic cylinder piston divides inner carrier and outer piston.During clamping workpiece, inner carrier first holds up workpiece, is then driven chuck by outer piston
Clamping workpiece, realizes self-centering clamping and the folder of clamping device of workpiece by numerical control program to the control of hydraulic system
The conversion of clamp force size.
The invention has the beneficial effects as follows, each modular construction optimized ensures that lathe has enough rigidity, it is ensured that lathe is at main shaft
Stable and friction when of high speed rotating；Multi-speed gear box is driven, it is possible to the main shaft of lathe is carried out by spindle drive motor
Stepless speed regulation, has enough output torques the main shaft low of lathe rotates when, so that it is guaranteed that lathe adapts to various processing
The demand of situation.The high-speed main spindle integrated improves precision and the stability of lathe while reducing base difficulty of processing.Main
Installing oil cylinder bottom axle, the piston driving chuck of oil cylinder carries out clamping to workpiece, eliminates the work such as manual correction, leveling workpiece
Make.The hydraulic system controlled by numerical control program can provide according to different machining status needed for the hydraulic oil of band pressure, thus
Make oild chuck obtain different size of clamping force, make workpiece have only to clamping and the most just can complete roughing and polish.Electricity
Moving knife tower can install multiple knife rest, can manufacture and design various knife rest according to the process requirements of part, and lathe autgmentability is strong.

Specific implementation method: optimizing the structure of design base 1, column 9 is arranged on base 1 by screw, electric component
It is placed on column 9 internal, sets up independent operating board 13 that lathe is controlled operation outside lathe.Column 9 top is installed vertical
To motor 10, longitudinal electric machine 10 drives crossbeam 8 to do on column 9 along the guide rail of column 9 by ball screw nut etc.
Vertically move.Body 7 is arranged on crossbeam 8, and the right-hand member of crossbeam 8 installs traverse motor 11, and traverse motor 11 passes through ball
Feed screw nut drives body 7 to laterally move on crossbeam 8 along the guide rail of crossbeam 8.Electric knives tower 6 is installed on body 7, electronic
Knife bar 5 is installed on cutter tower 6.The internally installed bascule of column 9 12, for entering the weight of crossbeam 8, body 7 and electric knives tower 6
Row balance.Main motor 17 is installed on base 1, by a multi-speed gear box 18, main motor 17 output speed can be changed
For at a high speed and two kinds of rotating speeds of low speed, to guarantee the requirement of various cutting.Drivewheel 19 installed by the outfan of multi-speed gear box 18, logical
Crossing driven pulley 15 and be transferred to main shaft 14, main shaft 14 is the high-speed main spindle integrated, and uses oil cooling to prevent main shaft 14 because of for a long time
The temperature rise run up and produce.Chuck 2 is attached to the oild chuck on main shaft 14 top.The bottom of main shaft 14 connects oil cylinder
16.Oil cylinder 16 is with inner carrier 4 and outer piston 3, and inner carrier 4 for holding up the position specified by workpiece, and outer piston 3 is used for controlling
The clamping of fabrication dish 2 with unclamp.During lathe work, control hydraulic system 20 by numerical control program, make the inner carrier 4 liters of oil cylinder 16
Rise, workpiece is held up appointment position, is then driven chuck 2 by Workpiece clamping by outer piston 3.After Workpiece clamping, inner carrier 4 moves back
Return to origin-location, leave the space of processing.The output of hydraulic system during roughing 20 can be set to by numerical control program
The hydraulic oil of elevated pressures, so that chuck 2 obtains bigger clamping force.After roughing, program first controls hydraulic system
The hydraulic oil of 20 pairs of oil circuit output lower pressures, makes the clamping force of chuck 2 reduce, then carries out polish, thus prevent workpiece
The deformation caused because clamping force is excessive during polish.
