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 one plane of milling is as process area on bent axle fan plate, this process area is in engine use without appointing
What use ensures that crank-shaft link neck 180 degree symmetrically uses, not only needs to occupy a machine tool, also need to occupy when being only used as processing
Manually, cost is virtually added.
Utility model content：
In conclusion in order to overcome the shortcomings of prior art problem, the utility model provides a kind of crank-shaft link neck and adds
Work fixture, it is one index dial of design, and index dial is set with and is fastenedly connected the small head end in bent axle, on index dial 180 ° it is right
Claim to set two card slots, while bayonet lock is set, bayonet lock is arranged on by block pin seat on the footstock of lathe, bayonet lock card during use
In a card slot on index dial, then start lathe the connecting rod neck in the same direction of bent axle is processed, completion of processing it
Afterwards, bayonet lock is removed out of card slot, bent axle rotates 180 °, bayonet lock is installed in another card slot of index dial, to bent axle
Remaining connecting rod neck be processed, need not on bent axle processing technology platform and realize the guarantor of 180 ° of symmetries of crank-shaft link neck
Card, has saved lathe and has saved a procedure, practical function is notable.
In order to solve the above technical problems, the technical solution adopted in the utility model is：
A kind of crank-shaft link neck fixture for processing, wherein：Including index dial, bayonet lock and block pin seat, the block pin seat is tight
It being solidly connected on the footstock of lathe, bayonet lock is hinged on block pin seat, and the index dial is sleeved on the small head end of bent axle, and
Be fastenedly connected with the small head end of bent axle, set on the index dial there are two card slot, two card slots on index dial 180 ° it is right
Claim distribution, the bayonet lock is corresponding with card slot.
Further, the index dial is fastenedly connected by the small head end of big jackscrew and bent axle.
Further, small jackscrew is provided on the block pin seat, bayonet lock is hinged by articulated shaft and block pin seat, small jackscrew top
Tight articulated shaft.
The beneficial effects of the utility model are：
1st, the utility model is one index dial of design, and index dial is set with and is fastenedly connected the small head end in bent axle, indexes
Two card slots are symmetrical arranged on disk for 180 °, while bayonet lock is set, and bayonet lock is arranged on by block pin seat on the footstock of lathe, is made
Used time bayonet lock is installed in a card slot on index dial, then starts lathe and the connecting rod neck in the same direction of bent axle is processed,
After completion of processing, bayonet lock is removed out of card slot, bent axle rotates 180 °, and bayonet lock is installed on to another card slot of index dial
It is interior, be processed in remaining connecting rod neck to bent axle, need not on bent axle processing technology platform and realize crank-shaft link neck
The guarantee of 180 ° of symmetries has saved lathe and has saved a procedure, and practical function is notable.
2nd, the utility model is simple in structure, easy to use, cost is cheap, is fastenedly connected using the small head end with bent axle
Index dial and bayonet lock corresponding with index dial realize to the clamping of bent axle, prevent the swing in Crankshaft Machining rotation process or alter
It is dynamic, while utilize the guarantee for card slot realization 180 ° of symmetries of crank-shaft link neck that 180 ° are arranged symmetrically on index dial.
Description of the drawings：
Fig. 1 is the structure diagram of the utility model；
1. bent axle, 2. index dials, 3. bayonet locks, 4. card slots, 5. big jackscrews, 6. small jackscrews, 7. block pin seats.
