Abstract
It is a kind of to adjust the high eccentric in numerically controlled lathe knife tower center, it is characterised in that: including eccentric collet, fastening screw, the bias collet is fixed in broach shell by broach shell fixing bolt, and knife tower composite drill is fixed in eccentric collet by fastening screw.Eccentric collet deviates center and is less than or equal to 0.3mm, can arbitrarily rotate adjusting within the scope of numerical control lathe guide rail abrasion 0.6mm, adjusting using eccentric center principle keeps nose center consistent with main shaft of numerical control machine tool center.The utility model passes through the subtle rotation adjustment of eccentric collet, is solved easily and quickly because numerical control lathe guide rail is worn, and when centering will appear frequently disconnected composite drill situation, reduces production efficiency, increase processing cost problem.When also solving the lesser internal screw thread of processing and external screw thread, point of a knife relief angle can be caused to generate interference, surface to be machined roughness is poor, influences product quality problem because point of a knife is lower than workpiece.
Description
Technical field
The utility model relates to a kind of eccentrics that adjusting numerically controlled lathe knife tower center is high.
Background technique
Numerically controlled lathe is basis and the core of factory automation, and numerically controlled lathe in use, is led for various reasons
The probability that rail is worn is very big, influences whether the precision and accuracy of numerically controlled lathe.Guide rail mild wear can make under entire knife tower
Drop, and be lower than 0.1 millimeter~0.3 millimeter of main shaft of numerical control machine tool center, in converted products centering on numerically controlled lathe because
Way rub, knife tower center are lower than the center of workpiece, and when centering will appear frequently disconnected composite drill situation, reduce production effect
Rate increases processing cost.It, can be because of knife when processing lesser internal screw thread and external screw thread in such equipment due to way rub
Point is lower than workpiece, causes point of a knife relief angle to generate interference, surface to be machined roughness is poor, influences product quality.In existing technology
In field, to solve the problems, such as that knife tower declines, need to repair numerical control lathe guide rail, general restorative procedure is: guide rail
Mild wear, shallow slot directly can be dug out in abrasion section with flat chisel, be polished flat with oilstone.Way rub is more serious, generally adopts
The method inlayed with high molecular material and the method using replacement guide rail, these methods require to carry out a large amount of people to machined surface
The disadvantages of work scraping has heavy workload, and the period is long, costly.
Summary of the invention
The purpose of this utility model is to provide a kind of eccentrics that adjusting numerically controlled lathe knife tower center is high, overcome factor
Lathe guide rail abrasion is controlled, the composite drill etc. that frequently breaks when will cause centering reduces production efficiency and influences lacking for product quality
Point does not need to repair numerical control lathe guide rail.
It is a kind of to adjust the high eccentric in numerically controlled lathe knife tower center, it is characterised in that: including eccentric collet, fastening spiral shell
Nail, the bias collet are fixed in broach shell by broach shell fixing bolt, and knife tower composite drill is fixed on cam lock by fastening screw
In set.Eccentric collet deviates center and is less than or equal to 0.3mm, can arbitrarily rotate tune within the scope of numerical control lathe guide rail abrasion 0.6mm
Section, being adjusted using eccentric center principle keeps nose center consistent with main shaft of numerical control machine tool center.
It is a kind of to adjust the high eccentric in numerically controlled lathe knife tower center, it is characterised in that: described device further includes chuck, card
Disk composite drill, dial gauge, chuck composite drill are clamped with chuck three-jaw, and dial gauge is inhaled on knife tower, compound in chuck with dial gauge
It bores and is translated back and forth between knife tower composite drill, rotating eccentricity collet is tuned up with the numerical value of reading, adjust and cause knife tower composite drill and card
Until disk composite drill is contour.
The technical effect of the utility model is: the utility model passes through the subtle rotation adjustment of eccentric collet, it is easily and quick
Solve because numerical control lathe guide rail is worn, when centering, will appear frequently disconnected composite drill situation, reduce production efficiency, increase plus
Work cost problem.When also solving the lesser internal screw thread of processing and external screw thread, point of a knife relief angle can be caused because point of a knife is lower than workpiece
Interference is generated, surface to be machined roughness is poor, influences product quality problem.

Specific embodiment
The embodiment for structure that according to the present invention will be described in detail below with reference to the accompanying drawings:
It is a kind of to adjust the high eccentric in numerically controlled lathe knife tower center, it is characterised in that: including eccentric collet 1, fastening spiral shell
2, chuck 3, chuck composite drill 4, dial gauge 5, knife tower composite drill 6, broach shell 7, broach shell fixing bolt 8 are followed closely, the bias collet 1 is logical
It crosses broach shell fixing bolt 8 to be fixed in broach shell 7, knife tower composite drill 6 is fixed in eccentric collet 1 by fastening screw 2, and chuck is compound
It bores 4 to be clamped with 3 three-jaw of chuck, dial gauge 5 is inhaled on knife tower, is put down back and forth between chuck composite drill 4 and knife tower composite drill 6
It moves, rotating eccentricity collet 1 is tuned up with the numerical value of reading, adjust until causing knife tower composite drill 6 and chuck composite drill 4 contour.It uses again
Broach shell fixing bolt 8, which is tightened, fixes eccentric collet 1.Ensure that the center upper-lower height of knife tower composite drill 6 in numerical control in this way
On the center of lathe spindle.6 front-rear direction (X-axis) of knife tower composite drill can use the cutter correction table on numerically controlled lathe control panel
It makes corrections, is also at 6 front-rear center of knife tower composite drill on the center of spindle of numerical control lathe, in this way in completion number lathe tool tower
The high tune-up of the heart.Make knife tower center and main shaft of numerical control machine tool center one by the reading rotating eccentricity collet 1 of dial gauge 5 to adjust
It causes.The knife tower central point that the numerical control lathe guide rail difference degree of wear can be found is high.The apparatus structure is simple, and operation easily, is protected
Product quality has been demonstrate,proved, has been improved work efficiency.Utilization can be widely popularized in numerically-controlled machine tool industry.
It, cannot the above content is specific preferred embodiment further detailed description of the utility model is combined
Assert that the specific implementation of the utility model is only limited to these instructions.For the ordinary skill of the utility model technical field
For personnel, make several equivalent substitute or obvious modifications without departing from the concept of the premise utility, and performance or
