Abstract
The utility model provides a torque wrench tightening head, which comprises a ratchet wrench, a wrench connector, a fixed bolt and a connection flat hole. The ratchet wrench adopts a common ratchet wrench in the existing market. The technical problem that when part of bolts are assembled on an engine, due to narrow installation position, the existing straight-handle elbow torque wrench cannot tighten an upper torque is overcome by utilizing the small swing angle of the selected ratchet wrench. The wrench connector (5) is provided with the ratchet wrench (1), a wrench connection square head (4) and the fixed bolt (2) for tightenning the ratchet wrench (1). A center distance (6) is reserved between a wrench connector flat hole (3) and the wrench connection square head (4). The front end of the wrench connector is provided with the connection flat hole. A handle of the ratchet wrench is in matching connection with the flat hole at the front end of the wrench connector. The utility model has the advantages of small swing angle, simple structure and low cost and is easy to improve.
Description
Affiliated technical field
The utility model relates to a kind of moment that tights a bolt in the engine assembling process that is applied to, utilize existing common ratchet spanner and torque spanner connector to transform and form, do not use to design and produce special-purpose torque spanner tappet head in addition, simple in structure, transform easily, easy-to-use.
Background technology
At present, the set bolt of part (nut) needs the screw-down torque of control bolt (nut) in the engine assembling process, and because the installation site of partial fixing bolt and the interference of other engine components, existing common staight shank type, curved head type torque spanner can not put because of bolt position is narrow bolt or because of the required amplitude of fluctuation of the handle of torque spanner greater than 30 degree, can't screw change bolt (nut) thus can not use torque spanner to control required moment.
Summary of the invention
For solving the problems of the technologies described above, the purpose of this utility model is to provide a kind of torque spanner tappet head, comprises ratchet spanner, set bolt, spanner connector, connecting hole.Described ratchet spanner is selected common ratchet spanner on the market for use, utilize the one-directional rotation of selected ratchet spanner and when tightening required minimum wobble angle go to the lavatory the set bolt of part in the engine assembling process certainly because of the narrow problem that can't use the torque spanner screw-down torque in position.Utilize the center, flat hole and relative dislocation the in square toes center, spanner connector rear end of spanner connector front end, avoid blocking required other parts that tight a bolt, solved can not use ordinary straight ansa, curved head type torque spanner make-up torque problem.The utility model overcomes the defective of prior art, and a kind of simple in structure, easy torque spanner tappet head of transformation is provided.
Technical solution of the present utility model is such: a kind of torque spanner tappet head, comprise ratchet spanner, spanner connector, connecting hole, set bolt, it is characterized in that the spanner connector has the flat hole of spanner connector, the spanner connector is equipped with spanner and connects square toes, set bolt, and ratchet spanner.
The spanner connector has the flat hole of spanner connector, tightens up with set bolt.
Assembly wrench connects square toes on the parallel direction in the flat hole of spanner connector, and vertical have an installing hole, and installing hole has set bolt, and installing hole communicates with the flat hole of spanner connector.
The flat hole of spanner connector is connected with spanner centre distance between the square toes.
Advantage of the present utility model is to utilize existing ratchet spanner and torque spanner transformation to form, change the center in the flat hole of spanner connector front end and the relative distance at spanner connector square toes center by adjustment, can avoid hindering the parts of torque spanner handle swing easily, reach required moment thereby tight a bolt, improvement cost is cheap, and is easy to use.
Description of drawings:
Fig. 1 is that the overall structure of a kind of torque spanner tappet head of the utility model is installed schematic isometric.
Fig. 2 is the overall structure axonometric drawing of a kind of torque spanner tappet head of the utility model.
Among Fig. 1～Fig. 2, ratchet spanner (1), set bolt (2), the flat hole of spanner connector (3), spanner connect square toes (4), spanner connector (5), centre distance (6), bolt mounting holes (7).
The specific embodiment
Most preferred embodiment of the present utility model is such, with reference to accompanying drawing, described torque spanner tappet head comprises that ratchet spanner (1), set bolt (2), the flat hole of spanner connector (3), spanner connect square toes (4), spanner connector (5), centre distance (6), spanner connector (5) has the flat hole of spanner connector (3), spanner connector (5) is equipped with spanner and connects square toes (4), set bolt (2), and ratchet spanner (1).Spanner connector (5) has the flat hole of spanner connector (3), ratchet spanner (1) and the handle flat hole of spanner connector (3) of packing into.Assembly wrench connects square toes (4) on the parallel direction in the flat hole of spanner connector (3).Ratchet spanner (1) is connected square toes (4) parallel direction with spanner.Install and fix bolt (2) on vertical, installing hole (7) communicates with the flat hole of spanner connector (3).The flat hole of spanner connector (3) is connected square toes (4) to be had more than the about 1cm of centre distance (6) with spanner.
Described ratchet spanner (1) is the handle of common ratchet spanner to be cut be short to required length.
It is to be connected with the connecting hole of employed torque spanner that described spanner connects square toes (4).The center in the flat hole of described spanner connector (3) can be set according to needed width with the relative centre distance (6) that described spanner connects square toes (4).Described ratchet spanner (1) is connected with the flat hole of spanner connector (3), tightens described set bolt (2) and can fix described ratchet spanner (1).
