Background technology：
Bent axle is the main rotation member on engine, after bent axle is connected with connecting rod, can accept the motion (reciprocal) up and down of connecting rod
Become to circulate (rotation) motion.Therefore bent axle is an important part of engine, and it includes two significant points:Trunnion
And connecting rod neck, trunnion are installed on cylinder body, connecting rod neck is connected with crank pin end pore, and connecting rod small end hole connects with steam-cylinder piston
Connect, the rotation of bent axle is the power source of engine.And the driving source of whole engine mechanical system.
Processing to crank-shaft link neck at present mainly includes turning and grinding, is graded mark according to I. C. engine crankshaft product quality
Quasi- JB/NQ/62.1-87, it is desired to which each connecting rod neck is ± 20 ' to the angular deviation Grade A of first connecting rod neck center line, to make inspection
It is more directly perceived during survey, 180 ° of symmetries of neck are commonly referred to as turned, at present, in machining crankshafts, 180 ° for guarantee crank-shaft link neck are right
Title degree requirement, it usually needs as process area, this process area is no in engine use to appoint the plane of milling one on bent axle fan plate
What use, ensure that crank-shaft link neck 180 degree symmetrically uses when being only used as processing, not only need to take a machine tool, also need to take
Manually, cost is virtually added.
The content of the invention：
In summary, in order to overcome the shortcomings of prior art problem, the invention provides a kind of crank-shaft link neck fixture for processing,
It is one index dial of design, and index dial is set with and is fastenedly connected the small head end in bent axle, and 180 ° are symmetrical arranged two on index dial
Individual neck, while set bayonet lock, bayonet lock is arranged on the footstock of lathe by block pin seat, and bayonet lock is installed on indexing during use
In a neck on disk, then start lathe and the connecting rod neck in the same direction of bent axle is processed, after completion of processing, by bayonet lock
Removed out of neck, bent axle rotates 180 °, and bayonet lock is installed in another neck of index dial, in remaining company to bent axle
Bar neck is processed, it is not necessary to the processing technology platform on bent axle and realize the guarantee of 180 ° of symmetries of crank-shaft link neck, save
Lathe and a procedure is saved, practical function is notable.
In order to solve the above technical problems, the technical solution adopted by the present invention is：
A kind of crank-shaft link neck fixture for processing, wherein：Including index dial, bayonet lock and block pin seat, the fastening of described block pin seat connects
Be connected on the footstock of lathe, bayonet lock is hinged on block pin seat, and described index dial is sleeved on the small head end of bent axle, and with song
The small head end of axle is fastenedly connected, and two necks, two necks, 180 ° symmetrical point on index dial are provided with described index dial
Cloth, described bayonet lock are corresponding with neck.
Technical scheme may also is that realization, the microcephaly that described index dial passes through big jackscrew and bent axle
End is fastenedly connected.
Technical scheme may also is that realization, and small jackscrew is provided with described block pin seat, and bayonet lock leads to
Cross jointed shaft to be hinged with block pin seat, small jackscrew holds out against jointed shaft.
Beneficial effects of the present invention are：
1st, the present invention is one index dial of design, and index dial is set with and is fastenedly connected the small head end in bent axle, 180 ° on index dial
Two necks are symmetrical arranged, while bayonet lock is set, bayonet lock is arranged on the footstock of lathe by block pin seat, bayonet lock during use
It is installed in a neck on index dial, then starts lathe and the connecting rod neck in the same direction of bent axle is processed, completion of processing
Afterwards, bayonet lock is removed out of neck, bent axle rotates 180 °, bayonet lock is installed in another neck of index dial, to song
Remaining connecting rod neck of axle is processed, it is not necessary to the processing technology platform on bent axle and realize 180 ° of symmetries of crank-shaft link neck
Ensure, saved lathe and saved a procedure, practical function is notable.
2nd, the present invention is simple in construction, easy to use, cost is cheap, point being fastenedly connected using the small head end with bent axle
Scale and bayonet lock corresponding with index dial realize the clamping to bent axle, prevent the swing in Crankshaft Machining rotation process or play,
The guarantee of 180 ° of symmetries of crank-shaft link neck is realized using 180 ° of necks being arranged symmetrically on index dial simultaneously.
Brief description of the drawings：
Fig. 1 is the structural representation of the present invention；
1. bent axle, 2. index dials, 3. bayonet locks, 4. necks, 5. big jackscrews, 6. small jackscrews, 7. block pin seats.
Embodiment：
