Description

A simple tool for clamping the crankshaft

technical field

The utility model relates to the technical field of engine assembling tools, in particular to a simple tool for clamping a crankshaft.

Background technique

In the process of engine assembly, the required components need to be assembled organically, and certain process requirements must also be met.

Wait. At present, when the 6MK engine is assembled, the way to clamp the crankshaft is to use a crowbar to hold the crankshaft, and give a certain resistance in the opposite direction of the crankshaft rotation, so as to clamp the crankshaft. When turning the crankshaft, the crankshaft is turned by shaking the crankshaft with both hands.

The existing method of clamping the crankshaft mainly has the following shortcomings: 1. To use a crowbar to hold the crankshaft, it is necessary to find a suitable force point on the engine, and it cannot interfere with other parts on the engine, resulting in low work efficiency. If the crowbar is loose, the crankshaft will not be clamped tightly, and the reliability is poor; 2. Due to the large torque required to rotate the crankshaft, it is time-consuming and laborious to rotate the crankshaft by hand. The torque is larger, making it more difficult to manually turn the crankshaft.

One end of the handle 1 is provided with a mounting plate 3 , and the mounting plate 3 is provided with more than two first mounting holes 4 . Specifically, there are nine first installation holes 4 . During use, if the first installation hole 4 is damaged, other first installation holes 4 can be selected for use. On the one hand, the work efficiency will not be affected, and on the other hand, the service life and Flexibility and practicality are higher. The positioning pin 2 is detachably installed in the first installation hole 4 . Through the positioning function of the two positioning pins 2, the tool can effectively rotate or clamp and position the crankshaft. During operation, the positioning pin 2 is installed in the appropriate first installation hole 4, and then the positioning pin 2 is inserted into the positioning hole on the crankshaft, and the crankshaft can be rotated or positioned through the handle 1. The operation is not only simple, convenient, time-saving and labor-saving, but also greatly improves the work efficiency and the reliability and stability of the clamping crankshaft compared with the manual rotation of the crankshaft in the prior art.

One end of the positioning pin 2 in this embodiment is a semicircular plug end. The semi-circular plug-in end plays a guiding role, so that the positioning pin 2 can be inserted into the positioning hole of the crankshaft accurately and quickly, and at the same time, the positioning hole on the crankshaft is effectively prevented from being damaged by the impact of the positioning pin 2. The phenomenon.
