Description
Technical field
The utility model belongs to connection rod of automobile engine forging field, and in particular to a kind of forging roll chela reprocesses processing work
Dress.
Background technique
Automobile engine is that the machine of power is provided for automobile, is the heart of automobile, influences dynamic property, the economy of automobile
And the feature of environmental protection, and the power of engine then derives from cylinder interior.Cylinder, which is exactly one, can be converted into the interior of fuel
The place of kinetic energy can be simply interpreted as, and fuel generates immense pressure and push piston up-down, pass through in combustor inner cylinder
Power is transmitted to crankshaft by connecting rod, is eventually converted into rotary motion, then by speed changer and transmission shaft, power is transmitted to driving wheel
On, so that automobile be pushed to advance.Since the working principle of engine is similar, basic structure is also just similar.Petrol engine
It is usually made of two great institutions five big systems, is crank link mechanism, valve actuating mechanism, fuel system, lube system, cooling respectively
System, igniting system, starting system.Wherein crank link mechanism is one of main transmission mechanism of automobile engine, it is by piston and song
Axis connection is got up, and the expanding gas pressure for acting on top land is transmitted to crankshaft, makes the linear reciprocating motion of piston reversibly
It is converted into the rotary motion of crankshaft, with output power.
Engine link at work, in addition to bearing the pressure that combustion chamber combustion gas generates, still suffers from vertical and horizontal
Inertia force.Therefore, engine link works under a complicated stress state, it is not only by the tension and compression stress of alternation but also by curved
Transverse stress.So engine link easily damages, it is accordingly used in the forging roll chela requirement pole of forging connection rod of automobile engine
Its is huge, and to save production cost in production, forging roll chela is usually required to reuse, thus be needed to forging roll chela
Abrading section carry out repair welding, reprocessed after repair welding.It is a pair of of forging roll chela of guarantee when reprocessing processing forging roll chela
Consistency needs a pair of of forging roll chela reprocessing processing together, and processing positioning in this way is just relatively difficult, it is difficult to ensure that it is processed
Precision.And the requirement to operator is also very high, it is necessary to have the experience of very abundant could be grasped.Therefore, how
The precision of its positioning process is also ensured under the premise of the consistency for guaranteeing a pair of of chela, making it have certain repeatability etc. is
Urgent problem to be solved.
Utility model content
The purpose of this utility model is that in view of the deficiencies of the prior art, it is simple to provide a kind of structure, easy to operate, error
Small, a kind of positioning process forging roll chela with high accuracy reprocesses processing tool.
The purpose of this utility model is achieved in that a kind of forging roll chela reprocesses processing tool, this reprocesses processing work
Dress includes forging roll chela, the clamping fixture seat for placing forging roll chela and the upper cover for fixing forging roll chela, the roller
Forging machine chela is made of chela body and the positioning clamping column being arranged in below chela body；The clamping fixture seat is in cylindrical shape, folder
The intermediate position of tool seat is machined with a clip groove, and the clip groove is a groove extended transversely through, processing among clip groove
There are two the location hole for placing positioning clamping column below forging roll chela, two location holes and the forging roll chela
Two positioning clamping columns of lower section are corresponding, and the outside of two location holes is machined with first bolt hole respectively, described
First bolt hole is the through-hole that clamping fixture seat bottom is extended to from clip groove, is set in two the first bolts hole there are two fixing bolt,
The fixing bolt passes through first bolt hole and the forging roll chela being placed in location hole is fixed；In the upper cover
Between position be machined with a processing hole coaxial with upper cover, the two sides in the processing hole are respectively provided with equidistant second spiral shell
Keyhole, second bolt hole are through-hole, two the first bolts on two the second bolts hole and clamping fixture seat on the upper lid
Hole is corresponding.
The advantages and positive effects of the utility model are as follows: this forging roll chela is reprocessed, tool structure for processing is simple, and operation is real
It is at low cost with convenience, working efficiency is also improved under the premise of guaranteeing a pair of of forging roll chela consistency when reprocessing, is more avoided
Error caused by because of the reason of the artificial.
Detailed description of the invention
Fig. 1 is the overall structure decomposition diagram of the utility model.
Fig. 2 is the top view of the utility model Fig. 1.
Fig. 3 is the use state of the utility model with reference to figure.
Specific embodiment
For the utility model in order to solve drawbacks described above, applicants have invented the application forging roll chelas to reprocess processing tool.
The application is described in detail with reference to the accompanying drawing,
As shown in attached drawing, it includes forging roll chela 9, the clamping fixture seat 1 for placing forging roll chela 9 that this, which reprocesses processing tool,
With the upper cover 8 for fixing forging roll chela 9;
Wherein, the forging roll chela 9 is made of chela body 10 and the positioning clamping column 11 being arranged in below chela body 10；
Wherein, the clamping fixture seat 1 is in cylindrical shape, and the intermediate position of clamping fixture seat 1 is machined with a clip groove 2, described
Clip groove 2 is a groove extended transversely through, and there are two for placing determining for 9 lower section of forging roll chela for processing among clip groove 2
