Technical solution of the present utility model is such, a kind of engine advance angle assembling adjustment instrument, comprise handle, sash weight fastening bolt, sash weight, straight pin, it is characterized in that cylinder end of body installation bent axle, the injection pump of engine is installed in engine cylinder block, sash weight is installed on the handle by the sash weight fastening bolt, and straight pin is installed on the handle.
Be equipped with scale on the handle.
Sash weight one end is meant aciculiform, and the other end is a balancing weight.
Straight pin installing hole on the handle is a circular hole, and the hole on the handle is a circular hole.
Straight pin installing hole on the handle is a slotted hole, and the hole on the handle is a slotted hole.
It is interference fit that straight pin is installed in handle, and the installing hole of sash weight and sash weight fastening bolt is to be slidingly matched.
The utility model has the advantages that: be equipped with the scale of measuring the corner angle on the handle, have two dowel holes on the handle, one is used for installing straight pin, and one is used for being contained on the bent axle and cooperates with alignment pin, and two alignment pin circular holes can be designed to long lumbar hole according to adapting to different bent axle size needs.Sash weight one end is made pointer shape, the other end is as balancing weight, gravity by self can keep motionless in vertical direction, and the sash weight fastening bolt is as fastening effect, and is middle as rotating shaft, the scale of the pointed handle of sash weight is the crank angle degree, promptly finish the assembling of engine advance angle and adjust, easy to use, easy to manufacture, simple in structure, engine advance angle accuracy rate when improving assembling.
