This scheme is through setting up handheld handle, make things convenient for the staff gripping, the movable rod is articulated with horizontal hinge, under natural state, the movable rod is in vertical state, during the use, at first put a bent axle bell crank on horizontal hammering block face, with first dead lever, the second dead lever is pressed close to completely with two perpendiculars of the bell crank that will measure, observe the relative position relation between movable rod and the vertical pole, if movable rod and vertical pole coincidence, then the contained angle of measuring bell crank and horizontal bell crank is exactly 120, satisfy the technological requirement.
Preferably, the first fixing rod, the second fixing rod, the vertical rod and the handheld handle are located on the same plane. This optimization scheme sets up the handheld handle in the plane that first dead lever, second dead lever and vertical pole are located, more conveniently holds the relative position relation of this measuring tool and the bell crank that awaits measuring, is favorable to improving the measuring accuracy.
Preferably, the lower end of the movable rod is fixedly provided with a counterweight ball. According to the optimization scheme, the movable rod is ensured to be in a vertical state in the measuring process by arranging the counterweight balls, and the measuring accuracy is further improved.
As optimization, the lower end of the movable rod is provided with external threads, and a threaded hole matched with the lower end of the movable rod is machined in the counterweight ball. This optimization scheme passes through threaded connection with counter weight ball and movable rod, makes the installation of counter weight ball more convenient, makes things convenient for the staff to select or change different counter weight balls according to the in-service use operating mode simultaneously.
The utility model has the beneficial effects that: the measuring tool is simple in structure, easy to manufacture and operate, and capable of obtaining the space angle of the crank which is relatively difficult to measure through simple operation, so that the production working efficiency is effectively improved.

1. the device comprises a first fixing rod, a second fixing rod, a third fixing rod, a vertical rod, a fourth fixing rod, a fifth fixing rod, a sixth fixing rod, a fifth fixing rod, a sixth fixing rod, a movable rod, a fifth rod, a sixth moving rod, a fifth moving rod, a fourth moving rod, a movable rod, a 5 and a handheld handle.
Detailed Description
In order to clearly illustrate the technical features of the present solution, the present solution is explained below by way of specific embodiments.
As shown in fig. 1, the large crankshaft angle measuring tool comprises a first fixing rod 1, a second fixing rod 2, a vertical rod 3 and a handheld handle 5 which are fixedly connected to a central pivot 6 and are sequentially arranged along the anticlockwise direction, wherein the first fixing rod, the second fixing rod, the vertical rod and the handheld handle are located on the same plane, the first fixing rod and the second fixing rod are mutually perpendicular, and the included angle between the second fixing rod and the vertical rod is 30 degrees. The included angle between the second fixed rod and the vertical rod can be adjusted, and the measurement requirements of different angles to be measured are met.
The center pivot 6 is also hinged with a movable rod 4 through a horizontal hinge shaft, the planes of the first fixed rod 1, the second fixed rod 2 and the vertical rod 3 are perpendicular to the horizontal hinge shaft, and the planes of the first fixed rod, the second fixed rod and the vertical rod are parallel to the movable rod.
In order to guarantee that the movable rod is in the reliability of vertical state in the measurement process, this embodiment has set firmly the counter weight ball at the lower extreme of movable rod. The lower extreme of movable rod is equipped with the external screw thread, processes on the counter weight ball to have the screw hole with the lower extreme adaptation of movable rod.
During actual measurement, one crank throw of the crankshaft is firstly placed horizontally, then the first fixing rod and the second fixing rod are placed on two vertical faces of flat sides of other crank throws, the first fixing rod and the second fixing rod are made to be tightly attached to the two vertical faces respectively, and meanwhile the spatial plane where the measuring tool is located is perpendicular to the central shaft of the crankshaft. Observe the relative position of movable rod and vertical pole this moment, there are three kinds of situations:
the first is that: the movable rod is overlapped with the vertical rod, which shows that the included angle between the angle of the measuring crank and the angle of the horizontal crank is 120 degrees, and the process requirement is met;
secondly, the following steps: the movable rod is deviated to the inner side, which indicates that the included angle between the angle of the measuring crank and the angle of the horizontal crank is more than 120 degrees and does not meet the process requirements, and the inner side refers to the left side of the vertical rod 3 in the figure 1;
thirdly, the method comprises the following steps: the movable rod is deviated to the outer side, which means that the included angle between the angle of the measuring crank and the angle of the horizontal crank is less than 120 degrees, and the outer side does not meet the process requirements, and the outer side refers to the right side of the vertical rod 3 in the figure 1. And when the measured included angle cannot meet the process requirement of the forging piece, correcting the crank throw.
The measuring tool disclosed by the utility model is simple in structure and easy to assemble, and meanwhile, the operation steps are very simple and easy to learn, so that the problem that the crank included angle is difficult to measure in the production process of the crankshaft is well solved.
