Description
Technical field
The invention belongs to machining equipment technical fields, and in particular to a kind of center adjustment dress for cooperating lathe chuck
It sets.
Background technique
Early in the 1950s, just having had already appeared the high-frequency motor spindle for being ground aperture, frequency converter at that time is adopted
With radio tube, although revolving speed is high, power is small, and torque is also small.The needs and power electronic device developed with high-speed cutting
The development of the computer technology of part, microelectronic component produces the frequency converter and vector controlled driver of all solid state original part；In addition
The appearance of admixture ceramics bearing, so that occurring at late 1980s, the beginning of the nineties for milling, turning, machining center
High-power, the big torque of equal processing, high-revolving electro spindle.Lathe is that most wide one kind is used in machine-building and repair factory
Lathe is known as " turner " using the worker of lathe, and lathe is considered as that the work of all devices is " female in mechanical processing industry
Machine ".Lathe is mainly used for processing axis, disk, set and other workpiece with rotary surface, based on cylindrical body.On lathe also
It can be processed accordingly with drill bit, reamer, reamer, screw tap, screw die and checkering tool etc..The rotations such as milling machine and drilling machine processing
Machinery be all to extend out from lathe.The main building block of lathe has: spindle box, change gear box, feed box, slide carriage
Each tailstock of case, knife rest, chuck etc., chuck are the mechanical devices for being used to clamp workpiece on lathe.Using being evenly arranged on chuck body
Movable jaw moves radially, the machine tool accessories of Workpiece clamping and positioning.Chuck is generally by chuck body, movable jaw and claw
3 part of driving mechanism composition.Minimum 65 millimeters of chuck body diameter, maximum up to 1500 millimeters, there is through-hole in center, to lead to
Cross workpiece or bar；There is cylindrical or short taper profile structure at back, is connected directly or by ring flange and machine tool chief axis end.Card
Disk is typically mounted on lathe, cylindrical grinder and internal grinder and uses, and can also cooperate with various indexing means, is used for milling machine and brill
On bed.Lathe process mainly carries out turnery processing, main working shaft-like, bar class, stick class or sleeve with workpiece of the lathe tool to rotation
The outer peripheral surfaces such as class regular part cylindrical by clamping with three-jaw chuck part on lathe, then cooperates top on tailstock, dress
It is clamping to determine parts to be processed, it after lathe tool is moved to machining position, is rotated by chuck with parts to be processed, part is carried out by lathe tool
Turnery processing.
Lathe or numerically controlled lathe of today are generally used for processing revolving body workpieces, generally pass through three-jaw self-centering chuck clamping
Workpiece, this chuck can realize quick clamping by fastening assembly, but workpiece reverse side needs then to carry out by secondary clamping
Processing, even if chuck is good again with lathe main shaft concentricity when installing, abrasion and gap as caused by claw long-time use
Excessive, so that the concentricity of workpiece centre axis and main shaft after fixed is poor, end face run-out is larger when workpiece rotation, needs not
Adjust the clamping force of three claws disconnectedly or under some claw or the diameter of axle pad modes such as copper sheet it is adjusted it is very numb
It is tired, so that production efficiency reduces and labor intensity is larger.
