Description

Technical Field

[0001] This utility model relates to the field of crankshaft manufacturing technology, specifically to a deburring device for crankshaft main shaft connecting rod necks. Background Technology

[0002] In crankshaft machining, after rough machining with MAG milling and turning, burrs will appear on both sides of the crankshaft's main journal and connecting rod journal. These burrs are caused by the rough machining tool pressing against the workpiece's side, creating a ring of fine, strip-like burrs. Because they adhere during machining, cleaning equipment cannot remove them completely, and they can only be manually removed. However, due to process limitations, they cannot be completely removed during manufacturing, resulting in burr residue on the finished product. Since engine assembly lines have extremely stringent cleanliness requirements, allowing no foreign matter inside the engine, these burr hazards, if not cleaned properly, are highly likely to end up on the assembly line and ultimately reach the customer, resulting in defective products.

The upper end of the guide shaft 43 is slidably connected to the linear guide rail 42, and the lower end is fixedly connected to the support plate 8.

[0024] In a further implementation, refer to Figure 4 The power assembly 1 includes a servo motor 11, a synchronous belt 12, and a motor drive shaft 13. The servo motor 11 is located above the support plate 8. The lower end of the motor drive shaft 13 passes through the support plate 8 and is connected to the transmission assembly 2. A bearing is provided between the motor drive shaft 13 and the support plate 8. The output shaft of the servo motor 11 and the upper end of the motor drive shaft 13 are connected by the synchronous belt 12.

[0025] In a further implementation, refer to Figure 5The transmission assembly 2 includes a power transmission gearbox 21, multiple transmission gears 22, and a positioning wire brush 23. The power transmission gearbox 21 is connected to the support plate 8 below and is connected to the motor drive shaft 13. The transmission gears 22 are located in the power transmission gearbox 21 and can be driven by the power transmission gearbox 21 to rotate synchronously. The positioning wire brush 23 is located below the power transmission gearbox 21 and is connected to the transmission gears 22.

[0026] The transmission gear 22 and the positioning wire brush 23 are positioned on both sides of the main journal and connecting rod journal of the crankshaft 7. Different types of crankshafts 7 are equipped with matching transmission components 2.
