Special equipment for drilling straight oil hole or inclined oil hole in crankshaft

Abstract

The invention relates to special equipment for drilling straight oil holes or inclined oil holes in a crankshaft, which is used for drilling the straight oil holes or the inclined oil holes in the crankshaft. The equipment is mainly composed of a machine tool body, a transverse moving workbench, a drilling power head, a rotary table workbench, an indexing transposition clamp, a crankshaft axial positioning clamp, a crankshaft radial positioning clamp, an electrical control system, a hydraulic control system and a pneumatic control system. Except for manual feeding and discharging, all the steps are completed automatically, the automation degree is high, the working efficiency can be effectively improved, the labor intensity is relieved, and meanwhile operation on a mechanical arm assemblyline is facilitated; and a MQL aerodynamic minimal quantity lubrication device is adopted, so that the production environment is thoroughly improved.

Description

technical field [0001] The invention relates to the technical field of auto parts manufacturing, in particular to a special equipment for drilling straight oil holes or oblique oil holes for crankshafts. Background technique [0002] With the continuous increase of annual output of crankshafts, the processing of straight and inclined oil holes of crankshafts has become the bottleneck of the entire production line. Due to the continuous development of advanced technology in the machinery industry, compared with the original SSK8119 crankshaft straight and inclined oil hole processing gun drilling machine, there are the following disadvantages: [0003] 1. During use, a large amount of sprayed gun drilling oil is used to cool the workpiece and lubricate the tool. However, due to the large amount of sprayed oil, a recycling equipment filtration system is equipped to filter the gun drilling oil. , and the circulating filtration system is too large and occupies a large area. ...

AI Technical Summary

Problems solved by technology

[0003] 1. During use, a large amount of sprayed gun drilling oil is used to cool the workpiece and lubricate the tool. However, due to the large amount of sprayed oil, a recycling equipment filtration system is equipped to filter the gun drilling oil. , and the circulating filtration system is too large and occupies a large area

[0004] 2. Operators will be exposed to a large amount of gun drilling oil during processing, tool changing, debugging, cleaning equipment, etc. Especially in summer, there is gun drilling oil mist around the machine tool, which poses a serious threat to the health of operators

[0005] 3. The iron filings after drilling contain a large amount of gun drilling oil. If they are directly discarded as iron filings, it will cause great harm to the environment; the transfer of gun drilling oil with iron filings will cause serious pollution at any time, so special personnel should be equipped to clean Iron filings are treated with oil dumping, resulting in a waste of human resources

[0006] 4. The working efficiency of the machine tool is low;

[0007] 5. In the filter system of the gun drilling oil, if the gun drilling oil with poor cleanliness passes through the oil hole of the gun drilling tool, it will be easily blocked by impurities. If the gun drilling oil cannot spray the workpiece smoothly, it will cause the gun drilling Cutting tool breakage, crankshaft and jig set are scrapped

[0008] 6. Use the top to tighten the top holes at both ends of the crankshaft to drill the oil hole. Since the crankshaft is a slender shaft, the radial force on the slender shaft is very large when drilling, the crankshaft may bend, and the machine tool vibrates greatly

[0009] 7. Due to the design of the gun drilling machine itself, the length of the gun drilling machine is very long, reaching 480-500mm. Therefore, it is necessary to equip the gun drilling machine with a very complicated guide device

If the oil temperature of the gun drill is too high, in addition to being unable to cool the workpiece and lubricate the tool, there may also be fires and cooler trips.

[0013] 11. After the top is tightened, it will automatically return, because it is not equipped with an alarm device, if drilling at this time, the phenomenon of knife breaking will inevitably occur
