Description
Technical field
The present invention relates to a kind of processing equipments of macrotype axes series parts, and in particular to a kind of for the big of marine diesel
The processing of type connection rod type workpiece positions and rotating device, belongs to diesel engine manufacturing technology field.
Background technology
The Set and Positioning of workpiece be machining in one it is relatively common the problem of, while be also one must be directed to workpiece it is each
Different processing request needs specifically solve the problems, such as, because different workpiece needs different frock clamps.High-grade digital control processing
One main advantages at center are exactly to have powerful, widely applicable universal fixturing system, and workpiece on it can be accurate
It positions and firm clamping, and can also need to convert different angles according to processing.However numerical control machining center is expensive,
Processing cost is fairly expensive, thus on standard machinery machining tool, generally all uses the universal fixturing of lower cost
To solve the Set and Positioning of workpiece.
Piston rod is the important moving component of marine diesel, is made of large cylindrical, stage casing circle and end pin outer circle.It is living
Fill in processing of the connecting rod on lathe and include cutting outlet pin outer end face, stage casing is justified and and piston head faying face and large cylindrical and ten
The flat end surface of prefix connection.
The piston rod of marine diesel is the very large heavy parts of volume, and processing at present carries out as follows:Boring machine
Process the rough turn outer circle of centre hole → lathe and overall length → depth drill deep hole processing → lathe car to centre bore → surface hardening heat at
Reason → lathe smart car → Boring machine processing end-face hole → grinding workpiece → polishing workpiece.As described above zero is set from upper lathe, tune-up
To the overall process machined, piston rod needs lathe above and below repeatedly, and is not directed at all on each platen for position
The automatic positioning equipment of piston rod, so being required for that more time is spent to carry out again to knife centering and setting every time
Zero-bit during so as to considerably increase the hole on time and non-cutting time before processing, the particularly outer garden of Boring machine processing, needs
Manually to carry out rotational workpieces with common cooperate such as driving using crow bar, this not only lowers production efficiency, be unfavorable for high-volume life
Production, and the man-hour of substantial amounts of lathe and lifting device is occupied, add processing cost.
The content of the invention
It is an object of the present invention to when overcoming existing piston rod process each process conversion, rotate and reposition
The deficiency of workpiece inefficiency provides a kind of large link rod class work pieces process positioning and rotating device, realizes large-scale workpiece
Ease rotation and automatic positioning function, so as to reach the technique effect for reducing labor intensity, improving production of parts.
Based on above-mentioned purpose, the technical solution that the present invention takes is as follows:
A kind of large link rod class work pieces process positioning and rotating device, are placed on the workbench of lathe simultaneously support link
Class workpiece, it is characterised in that:It is described positioning and rotating device include V-type positioning seat, load-bearing fixing piece, lifting bearing supporting block and
Lift-bolt;
The V-type positioning seat is fixed on the workbench, and top is provided with to position the connecting rod on cross section
Class workpiece and the V-notch for limiting the rotary freedom of the connection rod type workpiece in the horizontal plane;
The load-bearing fixing piece is fixed on the V-type positioning seat, and medial surface is equipped with half slot, and both sides are equipped with along vertical
The guide groove in direction;
The lifting bearing supporting block is arranged in the guide groove of the load-bearing fixing piece and is carried out up and down along the guide groove
Mobile, the plane opposite with the medial surface of the load-bearing fixing piece is equipped with semicircle thread groove in the lifting bearing supporting block, should
For the half slot of semicircle thread groove and the load-bearing fixing piece to synthesizing a cylinder cavity, the top of the lifting bearing supporting block is left
There are two the rolling bearings that can be rotated for right symmetrically connection;
The lift-bolt is arranged in the cylinder cavity that the semicircle thread groove is formed with the half slot, the lifting spiral shell
The external screw thread of bar and the internal thread of the semicircle thread groove mutually screw;
The lift-bolt rotated in the forward direction promotes institute by the thrust of the half slot of the load-bearing fixing piece by screw-driven
It states lifting bearing supporting block and lifts the connection rod type workpiece upwards, the connection rod type workpiece is made to turn on the rolling bearing around axis
It moves with conversion station;The lift-bolt of reverse rotation passes through screw-driven by the thrust of the half slot of the load-bearing fixing piece
It promotes the lifting bearing supporting block downward, the connection rod type workpiece is made to depart from the rolling bearing and falls into the V-type positioning
In the V-notch of seat, complete that the automatic capturing of the connection rod type workpiece is positioned and supported on new station.
Further, the lift-bolt is equipped with upper shoulder and lower shoulder, the upper end of the half slot be equipped with on this
The upper thrust surface of shoulder contact, lower end are equipped with the lower thrust surface contacted with the lower shoulder.
Further, it is equipped between the upper shoulder and upper thrust surface and between the lower shoulder and lower thrust surface
Antifriction gasket.
Further, the top of the lift-bolt is equipped with the square hole for coordinating square spanner.
Further, the positional symmetry median plane of the rolling bearing is overlapped with the plane of symmetry of the V-notch.
Compared with prior art, the beneficial effects of the invention are as follows:
1. pair workpiece is automatically positioned --- the present invention has certainly the circular cross section of axis body part using V-notch
The principle of dynamic positioning action, is provided with V-block on V-type positioning seat, thus when connecting rod is held in the V-notch, it can
Realize the automatic capturing of connecting rod transverse direction, operating personnel need not tune up after conversion station again every time, correction and setting coordinate zero
Position, substantially increases the efficiency of workpiece positioning and clamping, and the positioning and rotating device not only define connection rod type workpiece edge automatically
The degree of freedom of platen face transverse shifting, and define the freedom that connection rod type workpiece rotates in the horizontal plane automatically simultaneously
Degree.
Easily 2. station can be converted by swivel link class workpiece --- lift bearing when pulling lift-bolt rotation forces
When supporting block rises picking-up connection rod type workpiece, two rolling bearings can be such that the connection rod type workpiece of circular cross-section is easily turned
It is dynamic, it is achieved thereby that the quick rotation to connection rod type workpiece, significantly reduces labor intensity, improve the security of operation.
3. improve production efficiency --- machining piston connecting rod of the present invention is used, outer round tube hole and flat transverse plane can be one
It is completed in a process, this just substantially reduces processing technology, saves the non-cutting time for repeatedly tuning up and getting on or off the bus, greatly promotes
Operating efficiency.
