The invention discloses a kind of positioner being easy to berrette file hook bolt rapid processing and processing method thereof, described device includes three-jaw clamp shaft, thimble and movable thimble, snap-fit engagement section that described three-jaw clamp shaft rear end is arranged and lathe three-claw chuck is connected, described its front end of three-jaw clamp shaft arranges thimble, and described thimble arranges fastener；Described movable thimble and bearing fit are socketed on lathe center.The inventive method include successively being installed location, rough turn, finish turning shaft and flat bolt is domatic, car tooth, correction, forming step.The present invention uses three-jaw clamp shaft so that rough turn and finish turning pole face and flat bolt is domatic all can process at one time, and has both ensured bolt precision, has reduced mismachining tolerance, more save process time of unit bolt.Prior art forges machine work molding from blanking, processes a bolt used time average 27min, uses the inventive method processing used time average 15min.Present configuration is simple, and convenient mounting and clamping is processed fast and simple.
Description
Technical field
The invention belongs to Machining Technology field, belong to axle class processing technique field further, be specifically related to a kind of simple in construction, cheap, the positioner being easy to berrette file hook bolt rapid processing of the convenient mounting and clamping of reliable operation and method thereof.
Background technology
Bolt, by a head and screw rod class securing member dimerous, needs and nut screw connection, for being fastenedly connected two parts with through hole.In many equipment such as bolt is referred to as the rice of industry, is widely used in electronic product, engineering goods, digital product, power equipment, dynamo-electric engineering goods.The generally blanking of the processing technique of bolt, forge into just shape hair training, two ends centre hole beaten by annealing cooling, upper lathe, grab chuck with four blocks flat bolt head, simultaneously thimble withstand the rough turn pole face of bolt tail, finish turning pole face, reverse end for end that the flat bolt head of car two is domatic again, car tooth, correction, molding, tune turnery processing speed is slow the most in turn, and concentricity is low, mismachining tolerance is big, and labor strength is bigger.To this end, a kind of simple in construction of research and development, cheap, reliable operation, the positioner being easy to berrette file hook bolt rapid processing of convenient mounting and clamping and processing method thereof, it is with a wide range of applications.
Summary of the invention
It is an object of the invention to provide one and can be effectively improved bolt working (machining) efficiency, it is ensured that the dedicated positioning device being easy to berrette file hook bolt rapid processing of bolt machining accuracy；Second purpose is to provide a kind of method based on aforementioned means processing berrette file hook bolt.
The first object of the present invention is realized in, described device includes three-jaw clamp shaft, thimble and movable thimble, snap-fit engagement section that described three-jaw clamp shaft rear end is arranged and lathe three-claw chuck is connected, described its front end of three-jaw clamp shaft arranges thimble, and described thimble arranges fastener；Described movable thimble and bearing fit are socketed on lathe center.
The second object of the present invention be achieved in that the inventive method include successively being installed location, rough turn, finish turning shaft and flat bolt is domatic, car tooth, correction, forming step:
A, first accomplish fluently centre hole at workpiece two ends, three-jaw clamp shaft rear end is installed with lathe three-claw chuck, moves lathe guide rail, workpiece vehicle body end centre hole is coordinated with movable thimble, and make the flat bolt of thimble front end and workpiece domatic end centre hole coordinate, make fastener and workpiece snug fit simultaneously；
B, startup lathe, rough turn screw rod shaft and flat bolt are domatic；Finish turning screw rod shaft and flat bolt are domatic the most again；
C, then car tooth, correction, obtain the berrette file hook bolt processed through last molding.
The present invention uses three-jaw clamp shaft so that rough turn and finish turning pole face and flat bolt is domatic all can process at one time, and has both ensured bolt precision, has reduced mismachining tolerance, more save process time of unit bolt.Prior art forges machine work molding from blanking, processes a bolt used time average 27min, uses the inventive method processing used time average 15min.With 1 year certain factory 1200, such bolt of needs for counting, lathe power of motor 10KW, often degree electricity 0.5 yuan；1 year can using electricity wisely 1200 yuan；Present configuration is simple, cheap, reliable operation, and convenient mounting and clamping is processed fast and simple.
Accompanying drawing explanation
Fig. 1 is duty schematic front view of the present invention；
In figure: 1-three-jaw clamp shaft, 2-thimble, 3-movable thimble, 4-bearing, 5-Lathe thimble, 6-workpiece, 7-fastener, 8-scroll chuck.
Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings, but is any limitation as the present invention never in any form, based on present invention teach that any conversion or improvement made, each falls within protection scope of the present invention.
As shown in Figure 1, apparatus of the present invention include three-jaw clamp shaft 1, thimble 2 and movable thimble 3, snap-fit engagement section that described three-jaw clamp shaft 1 rear end is arranged and lathe three-claw chuck is connected, described its front end of three-jaw clamp shaft 1 arranges thimble 2, described thimble 2 arranges fastener 7；Described movable thimble 3 is connected on lathe center 5 with bearing 4 engagement sleeves.
Described fastener 7 is L-shaped, and its minor face is fixed in thimble 2 side.
A diameter of 20-30mm of described three-jaw clamp shaft 1.
Described thimble 2 is overall structure with three-jaw clamp shaft 1, and its thimble total length is 15-30mm.
Described thimble 2 is Split type structure with three-jaw clamp shaft 1, and described thimble 2 is arranged in the front end centre bore of three-jaw clamp shaft 1.
The front end of described thimble 2 is cone, and cone angle is 30 ~ 90 °.
Described fixing card 7 front end is longer than thimble 2 front end.
The inventive method include successively being installed location, rough turn, finish turning shaft and flat bolt is domatic, car tooth, correction, forming step, first centre hole is accomplished fluently at workpiece two ends, three-jaw clamp shaft 1 rear end is installed with in lathe three-claw chuck 8, mobile lathe guide rail, workpiece vehicle body end centre hole is coordinated with movable thimble, and make the thimble 2 front end domatic end centre hole of bolt flat with workpiece coordinate, make fastener 7 and workpiece 6 snug fit simultaneously；Starting lathe, rough turn screw rod shaft and flat bolt are domatic；Finish turning screw rod shaft and flat bolt are domatic the most again；Then car tooth, correction, obtains the berrette file hook bolt processed through last molding.
The operation principle of the present invention and work process:
The present invention uses three-jaw clamp shaft, by thimble top tight workpiece, fastener and workpiece fits and rotates, realize not carrying out under secondary clamping, the disposable processing domatic to pole face and flat bolt, both ensured bolt precision, reduce mismachining tolerance, more save the process time of unit bolt.
Adding man-hour, three-jaw clamp shaft is anchored in three-jaw (or four paws) chuck by lathe, thimble and movable thimble hold out against the two ends that need to process workpiece respectively；Fitted workpiece by fastener again, rotate realize pole face and the domatic processing of flat bolt by fastener rotational band part of starting building.Rough turn and finish turning pole face and flat bolt is domatic is not required to unload workpiece and again installs post-treatment and complete.
