Abstract

The utility model discloses a force moment coupling which comprises a connecting plate, two connecting pins symmetrically arranged on one side of the connecting plate, and a tool joint which is arranged on the other side of the connecting plate and corresponds to the middle position of the connecting pin. The size and the spacing of the connecting pin correspond to the threaded hole of the crankshaft flange. The force moment coupling has the advantage that the crankshaft flange is connected by the connecting pin at one side of the force moment coupling, and the tool joint at the other side of the force moment coupling is connected with the checking meter or other tools like a lever. When the force moment coupling is used for checking the rotating flexibility of the crankshaft and the plunger of the engine assembly, the tool joint is connected with the force moment checking meter, which is convenient to detect whether the force moment values of the crankshaft and the connecting rod conform to the requirement, and the assembling quality is ensured by the quantification flexibility. When the force moment coupling is used for make the crankshaft and the plunger aim the assembling position in the assemblage, the tool joint is connected with the tools like a lever and the crankshaft is easily and conveniently rotated, so the labor intensity of the operator is decreased and the work efficiency is enhanced. The force moment coupling has simple structure and easy use.

Description

The moment joiner

Technical field the utility model relates to a kind of engine crankshaft, the assistant tool when piston assembles, particularly a kind of moment joiner of being used for.

Background technique in the past engineering repair works or the user in the motor assembling work, rotation flexibility to engine crankshaft, piston detects, be personnel selection setting stick dynamic crankshaft or flywheel, with what feel to detect, also have assemblings such as bent axle, piston also to make bent axle, piston reach rigging position by bent axle or flywheel in people's setting stick dynamic crankshaft case; Operation in this way, owing to the shape of engine crankshaft or flywheel and assembly technology, sequential scheduling reason, operation is inconvenience very, also is not easy to adopt some to help rapid operation instrument, not only operator's labor intensity height, and inefficiency, simultaneously, can not quantize owing to rotate flexibility, operation is lack of standardization or nonstandard, thereby, can not improve the quality of motor assembling.

The summary of the invention the purpose of this utility model is for overcoming above-mentioned deficiency of the prior art, special a kind of labor intensity that can reduce the operator, the moment joiner of raising efficiency of assembling and assembly quality of disclosing.

The technical solution of the utility model is achieved in that it is by joining plate and symmetrically arranged two attachment pegs of joining plate one side, and the tool-joint that opposite side is installed with respect to described attachment pegs neutral position is formed; Described attachment pegs size is corresponding with the screw on the crankshaft flange with spacing.Described attachment pegs is used to connect crankshaft flange, its size, spacing position are determined according to the hole of different engine crankshaft flange plate, tool-joint then is used to connect the instrument of required use, its form is determined according to the instrument of required use, such as, resemble the instrument connecting head of socket wrench class, can be equipped with the polygonal cylinder or the polygonal hole of instrument with polygonal hole or polygonal cylinder, in a word, as long as phase mutual energy carry-over moment is just passable, for another example, join cylinder with circular hole and add and wear pin, pin is used for carry-over moment.

The profile of described tool-joint can be the polygonal cylinder, and establishes polygonal post hole in the middle of the polygonal cylinder.The instrument of socket wrench class is more common, and polygonal cylinder and post boring ratio are better processed, polygonal cylinder, post hole can be hexagonal, anise or triangle, four jiaos or the like.

Moment joiner of the present utility model, attachment pegs by moment joiner one side connects crankshaft flange, the tool-joint coupling torque of opposite side detects table or lever and so on instrument, when being used for checking the rotation flexibility of motor assembling crankshaft and piston, the tool-joint coupling torque detects table, whether the moment values that can measure bent axle, connecting rod, piston, cylinder body, piston ring, connecting rod bearing shell, main box very easily meets the requirements, and guarantees assembly quality with the quantification flexibility; When being used for assembling aligning rigging positions such as making bent axle, piston, tool-joint connects the instrument of lever and so on, makes turning crankshaft easily, conveniently, has reduced operator's labor intensity and has improved working efficiency; And it is simple in structure, easy to use.

Description of drawings: the utility model is described in further detail below in conjunction with drawings and Examples:

Fig. 1 is a moment joiner structure schematic representation

Fig. 2 is the crankshaft flange structural representation

Fig. 3 detects the list structure schematic representation for moment

Embodiment is shown in accompanying drawing 1～3, moment joiner of the present utility model is two tapped holes of side processing by the joining plate of making of steel plate 1, two attachment pegs, the 2 one end machining screw that make with copper rod, one end is a polished rod, after screw thread one end of attachment pegs 2 screws in a nut earlier, after being installed in the aforementioned threads hole again, use nut check at last, the opposite side of joining plate 1 is with respect to described attachment pegs 2 position intermediate, method with welding is fixed on tool-joint 3 on the joining plate 1 and forms, and described attachment pegs 2 is big or small corresponding with the screw 4 on the crankshaft flange with spacing.

Attachment pegs 2 is used to connect crankshaft flange, its size, spacing position are determined according to the screw 4 of different engine crankshaft flange plate, use the copper processing and fabricating, make it both guarantee certain intensity, can protect crankshaft flange screw 4 to be unlikely in rotation process, to be damaged again;

Tool-joint 3 is used to connect the instrument of required use, its form is determined according to the instrument of required use, present embodiment, tool-joint 3 outer surfaces are the Hexagon cylinder, instrument with Hexagonal jacket in cooperating and so on, make turning crankshaft easily, conveniently, reduced operator's labor intensity and improved working efficiency; Also processed the square post hole 5 that a square cylinder 7 with moment detection table 6 side adapts in the middle of tool-joint 3 end faces, when being used for checking the rotation flexibility of motor assembling crankshaft and piston, coupling torque detects table 6, whether the moment values that just can measure bent axles, connecting rod, piston, cylinder body, piston ring, connecting rod bearing shell, main box by moment detection meter reading dish 9 very easily when handle with sleeve 8 meets the requirements, and reaches the purpose that guarantees assembly quality with the quantification flexibility.

Certainly, the shape of tool-joint 3 is not limited to the foregoing description, such as, when the joint geometry on the moment detection table 6 changes, the square post hole 5 of tool-joint 3 end faces will adapt to it, even when moment detect table 6 adopt fully in during Hexagonal jacket, tool-joint 3 just becomes the Hexagon cylinder of an entity.In a word, above embodiment is only in order to explanation the technical solution of the utility model and unrestricted, and the technical solution of the utility model is made amendment or is equal to replacement, and it all should be encompassed in the middle of the claim scope of the present utility model.
