Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of shock absorber inner tube turning and milling, especially to a numerical control lathe for shock absorber inner tube turning and milling. BACKGROUND

[0002] The shock absorber inner tube is one of the core components of the shock absorber in the automobile suspension system, usually made of high-strength alloy steel or chromium-plated steel pipe, and its inside cooperates with the piston rod to form a hydraulic oil flow channel, and through precise control of oil damping, it realizes the buffering and energy absorption effect. The inner tube must have very high dimensional accuracy, surface finish and fatigue resistance to ensure the stable operation of the shock absorber under complex road conditions. During the manufacturing process, the inner hole and the outer circle need to be precisely turned, and the positioning groove or mounting hole is processed by milling process, and finally heat treatment and surface plating treatment are carried out to improve wear resistance and corrosion resistance.

[0003] The numerical control lathe for shock absorber inner tube turning and milling in the prior art is operated by multiple structures. The bed body is usually made of cast iron material, which is cast by special process and has reinforcing ribs inside, so it is stable and shock-resistant. The guide rail is usually of roller type, which is wear-resistant and high-precision. The spindle unit is the core, and the high-precision electric spindle can realize high-speed rotation, and the C-axis can complete precise angle positioning. The power tool turret has multiple stations and can quickly switch between turning tools and milling tools. The tail seat cooperates with a special clamp to ensure firm clamping of the inner tube. The milling module integrates a separate spindle to realize multi-axis linkage. The cooling system cools down by high-pressure injection of coolant.

[0004] When the conventional numerical control lathe is used to process the shock absorber inner tube, the operator needs to frequently use the chip hook to manually clean the accumulated metal chips due to the lack of an automatic chip removal system. During this process, the worker needs to be close to the high-speed rotating tool or workpiece, which is easy to be scratched by the flying iron chips, and even the limbs may be caught in the equipment due to operation errors, which poses a serious safety hazard. In addition, manual chip removal is low in efficiency and has a long interruption time in the processing, which further restricts the utilization rate of the equipment and the production rhythm. Therefore, a numerical control lathe for shock absorber inner tube turning and milling is proposed to solve the above problems. UTILITY MODEL CONTENTS
