Description

Technical Field

[0001] This utility model relates to the field of crankshaft machining, and in particular to a fixing component for crankshaft machining. Background Technology

[0002] The crankshaft is the main rotating component of an engine, typically made of carbon structural steel, ductile iron, or high-strength alloy steel. It converts the reciprocating motion of the piston into its own cyclic rotation, bears the force transmitted from the connecting rod and converts it into torque output, driving other accessories on the engine. It is the power source for the engine and even the entire mechanical system.

[0003] When the engine is running, the piston reciprocates linearly within the cylinder. The combustion of the compressed air pushes the piston, which transmits force to the crankshaft via the connecting rod, causing the crankshaft to rotate. This converts linear motion into rotational motion, thereby providing power to vehicles or other equipment.

[0004] The production process of crankshafts involves multiple aspects, such as rough machining, finish machining, surface treatment, and inspection and testing. During these processes, the crankshaft needs to be fixed. Application number CN202020977869.2 discloses a jig for machining the eccentric part of a crankshaft, solving the problems of poor clamping and fixing effect, inconvenient adjustment, narrow applicability, and poor practicality of existing technologies. However, when using this device, after the base plate is fixed, the front and rear positions of the crankshaft cannot be adjusted, resulting in poor adaptability to different processes. Furthermore, after fixing the crankshaft, it cannot be rotated, leading to the need to repeatedly loosen and re-fix it when multiple machining operations are required for different parts (such as crankshaft drilling), thus affecting the use of the fixing device and reducing processing efficiency.

[0005] Therefore, it is necessary to provide a fixing component for crankshaft machining to solve the above-mentioned technical problems. Utility Model Content

[0006] This utility model provides a fixing component for crankshaft machining, which solves the problem that in some existing crankshaft machining fixing components, it is not convenient to move the crankshaft back and forth when the base plate is fixed, and the crankshaft cannot rotate, which affects the machining efficiency.

[0011] Preferably, a drive motor is provided at the bottom of the inner wall of the movable plate, and the output end of the drive motor extends through the inner wall of the movable plate to its top.

[0015] Beneficial effects:
