Description

Technical Field

[0001] This invention relates to the technical field of crankshaft machining, and more specifically to a crankshaft machining equipment and machining method. Background Technology

[0002] The crankshaft is the most important component in an engine. It bears the force transmitted from the connecting rod and converts it into torque, which is then output through the crankshaft to drive other accessories on the engine.

[0003] After machining the crankshaft, it is essential to thoroughly clean it, especially the oil holes. These areas are in contact with bearings or bushings, and any iron filings or other impurities inside can damage the oil film, causing problems such as crankshaft connecting rod jamming or crankshaft seizure. Therefore, a comprehensive cleaning of the crankshaft's oil holes is necessary.

[0004] Currently, the traditional method for cleaning crankshaft internal oil holes generally uses a through-type cleaning machine. This method can clean the crankshaft exterior, but it is not easy to clean the crankshaft interior. Ordinary high-pressure fixed-point cleaning machines for cleaning oil holes have limitations. Because the oil hole diameter is too small (φ4~φ5mm), the high-pressure water or air flow can only be sprayed into the crankshaft oil hole through the orifice, and the nozzle cannot penetrate deep into the oil hole. This cannot guarantee that the inner wall of the oil hole is cleaned thoroughly. Furthermore, the entire process requires workers to wear masks and hold high-pressure water guns or high-pressure air guns, making the working environment relatively dirty and harsh.

[0005] Therefore, how to solve the problem that existing cleaning equipment cannot clean the inner wall of the oil hole in the crankshaft is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0006] The purpose of this invention is to provide a crankshaft processing equipment and processing method to solve the above-mentioned defects caused by the prior art.

The lower end of the fixing frame (301) located directly above the connecting rod journal on the crankshaft component (311) is vertically welded to the connecting rod component (312), and the connecting rod (312) is rotatably connected to the connecting rod journal of the crankshaft component (311).

2. The crankshaft processing equipment according to claim 1, characterized in that: The processing method is as follows: S1: Place the front and rear shafts on the crankshaft part (40) on the support blocks (201) on the left and right sides respectively, and place the main journal and connecting rod journal on the crankshaft part (40) on the corresponding sealing ring (306) respectively. S2: The piston rods of the hydraulic cylinders (105) on the left and right sides extend and drive the corresponding clamping blocks (204) to press upward and inward against the upper side of the support block (201), and press the front end shaft of the crankshaft part (40) against the upper side of the friction belt (212). At the same time, the front and rear sealing covers (111) are closed synchronously. S3: The piston rods of all the hydraulic cylinders (303) extend and drive the corresponding sealing rings (308) to press upward and inward against the upper side of the sealing rings (306), and seal the main journal or connecting rod journal on the crankshaft part (40) therein; S4: The friction belt (212) is driven by the electric motor (208) to rotate, and the crankshaft parts (40) are driven to rotate synchronously. S5: High-pressure oil is sprayed out through the oil injection hole (112a) on the oil injection pipe (112) and sprayed to wash the outer surface of the crankshaft parts (40); S6: First, introduce the high-pressure oil into the sealing ring one (306) and sealing ring two (308), then enter the crankshaft part (40) through the hole at the main journal or connecting rod journal on the crankshaft part (40), and flush the oil hole in the crankshaft part (40); S7: The piston rods of all hydraulic cylinders 2 (303) retract and drive the corresponding sealing rings 2 (308) downward and outward away from the upper side of sealing ring 1 (306); S8: The piston rods of the hydraulic cylinders (105) on the left and right sides retract and drive the corresponding clamping blocks (204) downward and outward away from the upper side of the support block (201), and release the clamped crankshaft parts (40). At the same time, the front and rear sealing covers (111) are opened simultaneously. S9: Remove the oil-washed crankshaft parts (40).

3. The crankshaft processing equipment according to claim 1, characterized in that: The bottom of the sliding groove one (201a) is coaxially provided with an arc-shaped oil retention groove one (201b), and an oil guide hole (201c) is provided in the center of the bottom of the oil retention groove one (201b). The bottom of the sliding groove two (204a) is coaxially provided with an arc-shaped oil retention groove two (204b).

4. The crankshaft processing equipment according to claim 1, characterized in that: The first retainer (203) has an oil passage groove (203b) at both ends of the first oil retention groove (201b), and the second retainer (206) has an oil passage groove (206b) at both ends of the second oil retention groove (204b).
