Description

Technical Field

[0001] The utility model belongs to the technical field of automobile crankshafts, and more specifically, particularly relates to an automobile crankshaft oil hole cleaning tool. Background Art

[0002] The crankshaft is the most important component in the engine. It bears the force transmitted from the connecting rod and converts it into torque, which is output through the crankshaft and drives other accessories on the engine to work. The crankshaft is subjected to the combined effects of the centrifugal force of the rotating mass, the periodically changing gas inertia force and the reciprocating inertia force, causing the crankshaft to be subjected to bending and torsional loads.

[0003] Based on the above, the inventors have found the following problems: some traditional methods for cleaning the crankshaft oil holes of automobiles mainly involve workers inserting a cleaning brush into the oil hole and moving it back and forth for cleaning, but this not only increases labor costs, but also reduces work efficiency.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and an automobile crankshaft oil hole cleaning tool is provided to achieve a more practical purpose. Utility Model Content

[0005] The purpose and effect of the automobile crankshaft oil hole cleaning tool of the utility model are achieved by the following specific technical means:

[0011] Furthermore, a pair of support blocks are installed on the upper end surface of the workbench at a side away from the groove, and arc-shaped clamping blocks are installed on the upper end surfaces of the pair of support blocks.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] Through the coordinated use of sliders, bolts, rotating handwheels, motors and lead screws, firstly, the position of the slider is adjusted according to the position of the oil holes on the same batch of crankshafts, so that the cleaning brush on one side of the slider is aligned with the position of the oil holes on the crankshafts, and the rotating handwheel is turned to drive the bolt to rotate. The bolt is adapted to the threaded groove on the upper end face of the slider, so that the slider can be fixed after the bolt is rotated to a certain extent. Then the motor is started, and the motor drives the lead screw to rotate clockwise and counterclockwise. The lead screw drives the slider to reciprocate through its own rotation, and the slider drives the support rod to move. The support rod drives the cleaning brush to be inserted into the oil hole for reciprocating motion through the first connecting rod and the second connecting rod, so that the oil hole can be quickly cleaned, replacing manual cleaning, thereby reducing the output of labor costs, and also improving work efficiency.
