Description

TECHNICAL FIELD

[0001] The utility model relates to numerical control machine tool technical field, concretely relates to a numerical control planer boring and milling machine on -line cleaning system. BACKGROUND

[0002] At present, the planer boring and milling machine is widely used in the metal processing field, but a large amount of metal chips will be generated in the processing, if the chips cannot be removed in time, the processing precision will be affected, the machine parts will be damaged, and even the safety of the operator will be endangered. In the prior art, the following cleaning methods are mainly used:

[0003] Compressed air blowing: this is the most common cleaning method at present, the chips are blown away from the processing area by high-pressure airflow. However, this method has obvious defects: first, the high-speed airflow will cause the chips to scatter, pollute the workshop environment and increase the difficulty of subsequent cleaning; secondly, for the chips mixed with oil stains, the airflow is difficult to completely remove, and the residues will adhere to the surface of the machine; thirdly, the consumption of compressed air is large, and the energy consumption is high, which does not meet the requirements of modern green manufacturing.

[0004] Fixed electromagnetic chip removal: although it solves the problem of chip scattering, it has the following disadvantages: first, the fixed magnetic field will interfere with precision machining, especially for magnetic sensitive workpieces and measuring instruments; secondly, the electromagnet needs to be powered off regularly for cleaning, which must interrupt the processing process and affect the production efficiency; thirdly, it is completely ineffective for non-ferromagnetic materials such as aluminum alloy, copper alloy and the like.

[0005] Mechanical scraper: the chips are scraped into the collecting device by the mechanical scraper. This method is effective in dry environment, but in actual processing, the cutting fluid and lubricating oil will make the chips form a viscous mixture, which is easy to cause the scraper to be blocked. In addition, the scraper is seriously worn after long-term use, and needs to be replaced frequently, which has high maintenance cost.

[0006] More importantly, most of the existing cleaning devices lack intelligent detection function, and cannot judge the cleaning effect in real time, often requiring manual secondary inspection. In addition, the traditional chip collecting system is designed in an open type, and the chips are easy to scatter again during transfer, causing environmental pollution.

[0007] In view of the above technical bottleneck, the utility model provides an innovative solution, which realizes automatic cleaning in the processing process through the organic combination of the rotating electromagnetic chip removal device and the multispectral detection technology, avoiding the inherent defects of the traditional method and adapting to the complex oil environment.

[0019] The detection wavelength of the infrared sensor is 3-5 μm, and the polarization camera is provided with a 0° / 45° / 90° three-way polarization filter.

[0023] 1. Efficient cleaning and accurate detection: through the cooperative work of the rotating electromagnetic chip-adsorbing roller and the multispectral detection module, the real-time adsorption and intelligent monitoring of the chips in the machining process are realized.

[0024] 2. Spatial Adaptability and Processing Continuity: The unique 15° tilt installation design maintains a safe distance of 30-50mm between the electromagnetic roller and the cutting tool, completely avoiding interference with the processing path. The height adjustment module (guide rail slider mechanism) provides a rapid positioning capability of ±25mm, which can complete the adaptation of workpieces of different heights within 10 seconds, realizing simultaneous "processing-cleaning", improving production efficiency by more than 27% compared with traditional downtime cleaning methods.

[0025] 3. Energy Saving, Environmental Protection, and Intelligent Maintenance: The closed-loop negative pressure recovery system reduces energy consumption for debris transfer by 42%, and combined with the debris compression device in the debris collection box with a 3:1 compression ratio, it effectively reduces waste volume. The full-material alarm sensor and self-lubricating bearing design extend the maintenance cycle to 2000 hours, reducing maintenance frequency by 83% compared to traditional scraper-type cleaning systems.
