Description
Technical field
The present invention relates to a kind of processing unit (plant), especially a kind of prefabricated rods processing unit (plant).
Background technique
Prefabricated rods can be used to the material preforms of drawing optical fiber.Preform is the core for manufacturing quartzy series fibre
Raw material.It needs to carry out combustion heating work to product using flame burner in prefabricated rods production process.Existing flame burner
Table device is fixed bracket structure, and blowtorch is always held at alignment pieces center, can not automatic open-close and point
Firer makees, and influences operating space in a non-operative state, has obstruction to the clamping and disassembly of workpiece；In addition existing flame burner
Without cooling provision for thermal insulation on table device, the high temperature heat generated when blowtorch burns work to workpiece is easily to related elements
It damages, it is highly desirable to install cooling heat-insulated device additional.
When special purpose machine tool is processed, it is desirable that upper lower table clamping large-scale workpiece rotation, intermediate workbench add workpiece
Work.But workpiece size length is inconsistent, cause three workbench will independent drive control, independent brake locking, but to coaxial
Degree requires height, and impulse stroke is long.
Ball-screw be convert rotary motion to linear motion, or by transform linear motion be rotary motion it is ideal
Product.Ball-screw is actuated element most-often used on machine tool and precision machinery, and major function is by rotary motion
Linear movement is converted, or torque is converted into axial repeated action power, while having both high-precision, invertibity and efficient spy
Point.Due to the frictional resistance with very little, ball-screw is widely used in various industrial equipments and precision instrument.Ball-screw
It is made of screw rod, nut, steel ball, pre- tabletting, reverser, dust excluder.Its function is that rotary motion is converted to linear motion,
Bearing exactly is become to roll by this further extension for being Ai Kemu screw rod and development, the significance of this development from sliding action
Movement.
Since ball-screw dead weight and material property limit, when ball-screw length is too long, then it is difficult to protect
Card lead screw is able to maintain linear state, so as to cause lead screw bending, the precision of Machine-Tool Control is caused to reduce.
Existing chuck can be divided into mechanical chuck, air spider and oild chuck by driving structure point.
The mechanical chuck of the prior art generally comprises main body rack, helix swiveling plate, bevel gear, allen wrench, clamping jaw, folder
Pawl is slidably arranged in the sliding slot of main body rack, and helix swiveling plate engages driving clamping jaw sliding, bevel gear and helix swiveling plate with clamping jaw
Tooth engagement is bored at edge, and allen wrench and bevel gear fix and be rotatably arranged on main body rack side.
Mechanical chuck generally manually clamping, spanner drive screw thread disc spins, drive claw on screw thread disk forward
It screws, clamping force is controlled by operator.Air spider and oild chuck, will by pull rod by pneumatic cylinder and hydraulic cylinder force
Power passes to chuck, and chuck is driven to clamp.
But mechanical chuck low efficiency relies on manpower.Air spider and oild chuck can realize automatic control, but special circumstances
Human intervention with regard to more troublesome, realize difficult by crawl.
