Description
Technical field
The utility model belongs to a kind of fixture of Machining of Connecting Rod, is mainly used for gonnecting rod body, connecting rod cap while processing two sides.
Background technology
Core component (see Fig. 1) of the connecting rod as engine, is made of gonnecting rod body A and connecting rod cap B.In process,
In have a procedure, the two sides C of gonnecting rod body A and connecting rod cap B are processed respectively, typically on gonnecting rod body and connecting rod cap
After lower both ends of the surface are ground, using end face as positioning datum, after clamping, then milling one side is overturn again, with the one of rigid milling
Side is positioning datum, then milling another side.Special fixture will be made to the connecting rod of each different size and coordinate processing
Equipment.Such processing method is cumbersome, time-consuming, and production efficiency is relatively low, and the economic input for making fixture is larger, and
The dimensional uniformity of the gonnecting rod body A and connecting rod cap B that process are poor, bring and seriously affect to subsequent assembly process, are not suitable with
The requirement of mass production.
Utility model content
The main technical problems to be solved in the utility model and purpose are：Added according to current gonnecting rod body and connecting rod cap two sides
Insufficient existing for work, design a kind of new gonnecting rod body and connecting rod cap process the fixture of two sides simultaneously.Fundamentally overcome operation
It is cumbersome, fixture is of high cost, the phenomenon of the dimensional uniformity difference of gonnecting rod body and connecting rod cap, reach and effectively improve production efficiency, drop
To cost, ensures the processing quality of gonnecting rod body and connecting rod cap, adapt to the requirement produced in enormous quantities completely.
The main technical schemes of the utility model：The fixture include pedestal, U-shaped piece, it is gusset, backup plate, small head bore mandrel, big
Head bore mandrel, bolt, nut, backing plate, cushion cover, washer, U-shaped pressing plate, concrete structure：A, pedestal and backup plate are welded as at a right angle
One holder is simultaneously reinforced with gusset；B, in backup plate lower part, the left end of big end hole mandrel is passed through to the cushion cover being connected with backup plate,
It is used in combination nut, washer to fasten, then the right end of big end hole mandrel is packed into U-shaped pressing plate and nut；C, on backup plate top, by small head bore
Mandrel passes through the opening location hole of backing plate, backup plate, and nut, washer is used in combination to fasten.
The utility model is proved by practical application：Purpose of design is fully achieved, the clamp structure is simple, easy to manufacture；Work
It is easy to operate when making, improve five times of efficiency or more；The gonnecting rod body of processing and the dimensional uniformity difference qualification rate of connecting rod cap are up to 100%；
The cost for making fixture is greatly lowered, and the demand of mass production is fully met.

Specific implementation mode
With reference to Fig. 2,3, the main technical schemes of the utility model are illustrated：The utility model includes pedestal 1, U-shaped
It is block 2, gusset 3, backup plate 5, small head bore mandrel 6, big end hole mandrel 7, bolt 8, nut 9, backing plate 10, cushion cover 11, washer 12, U-shaped
Pressing plate 13, concrete structure：A, pedestal 1 and backup plate 5 are welded as a holder at a right angle and are reinforced with gusset 3；B, under backup plate 5
The left end of big end hole mandrel 7 is passed through the cushion cover 11 being connected with backup plate 5 by portion, is used in combination nut 9, washer 12 to fasten, then will be big
The right end of head bore mandrel 7 is packed into U-shaped pressing plate 13 and nut；C, on 5 top of backup plate, small head bore mandrel 6 is passed through into backing plate 10, backup plate
Opening location hole, be used in combination nut 9, washer 12 fasten.
With reference to Fig. 2,3, the operation principle of the utility model：1, fixture is mounted on platen first, according to even
The specification of bar is debugged.2 connecting rod cap B are packed on U-shaped piece 2 and position, and gonnecting rod body A is packed into size head bore mandrel, is made
Gonnecting rod body, the end face of connecting rod cap and the plane of cushion cover 11 are sticked to form component 4, are inserted into U-shaped pressing plate 13, then twist nut 9
Enter big end hole mandrel 7, is tightened to securing position.3, start processing button, carried out by the program that process equipment has been debugged in advance same
When Milling Process two sides.The mechanism can also be used for monoblock type connecting rod（After gonnecting rod body, connecting rod cap bolt combination）Two sides
It processes simultaneously.
With reference to Fig. 2,3,5,6, the utility model is applicable to the connecting rod two sides of different size while processing, and only needs basis
The diameter of phi of the large and small head bore of connecting rod1、Φ2, select corresponding big end hole mandrel 7 and small head bore mandrel 6, connecting rod centre-to-centre spacing L
It can be adjusted by the opening location hole at 5 top of backup plate.
The utility model has been used for the Machining of Connecting Rod of the plurality of specifications such as YAE, JL474Q, JL474Q1, YC5, YY5, M15A,
Effect is preferable, and purpose of design is fully achieved.
