Description

Technical Field

[0001] The present application relates to the technical field of crankshaft processing, and in particular to a crankshaft processing drilling machine. Background Art

[0002] The crankshaft is a common and important component in mechanical engineering. It plays a vital role in many mechanical equipment. It is usually used to convert rotational motion into reciprocating motion, or reciprocating motion into rotational motion. The structural design and performance of the crankshaft directly affect the operating efficiency and stability of the entire mechanical equipment.

[0003] Patent publication number "CN217018701U" discloses "a drilling machine for crankshaft blank processing", which includes a workbench, a pushing frame and a top frame. A plurality of crankshaft blanks are placed on the upper end of a movable plate, and then an electric push rod 2 pushes the lower pressure plate so that a pressing roller presses and fixes the crankshaft blank. Then the motor drives the drill rod to rotate, and the electric push rod 1 pushes the push box to move so that the drill rod drills holes in the crankshaft blank. Then the motor drives the slider through the screw to move the clamping frame, thereby drilling holes in other crankshaft blanks. This solves the problem that most of the existing crankshaft blank drilling devices place a single crankshaft blank on a workbench and fix it, and then drill holes in it. This drilling method is inefficient and can only drill a single hole, and most of the fixing effects are poor.

[0004] When the device in the above patent performs drilling operation on the crankshaft blank, if the crankshaft blank is too short and exceeds the standard range of the device design, it may make the drilling operation difficult to carry out effectively, thereby adversely affecting the production efficiency. Therefore, in order to ensure the smooth progress of the drilling operation and improve the production efficiency, the drilling operation device should be optimized and improved.
