Description

Technical Field

[0001] The utility model relates to the technical field of numerical control processing equipment, and more specifically to a window system for numerical control equipment. Background Art

[0002] During the processing of CNC machine tools, cutting fluid, metal chips and stains will indiscriminately block the perspective window on the safety door, making it impossible for the operator to observe the processing status in real time.

[0003] In order to solve this observation problem, the current conventional solution is to manually remove the cutting fluid, metal chips and stains attached to the perspective window regularly, which will bring safety hazards and increase the workload.

[0004] At present, the Korean patent publication number KR102533588B1 discloses a CNC lathe perspective window enclosure device, which is to install a scraper on the front side of the perspective window on the safety door. One way is that the scraper is movable left and right, and the moving scraper is used to scrape off the cutting fluid, metal chips, and stains on the perspective window; another way is to fix the scraper at the middle bottom of the perspective window, and the scraper rotates to form a fan-shaped motion trajectory to scrape off the cutting fluid, metal chips, and stains on the perspective window.

[0005] Using this scraper to scrape off the cutting fluid, metal chips, and stains on the perspective window can avoid the safety hazards caused by manual impurity removal. However, when the scraper pushes the metal chips, it may cause scratches on the perspective window. Moreover, the scraper is made of soft rubber material, and long-term contact with cutting fluid and metal chips will be damaged. In order to ensure the visual effect of observation, the scraper needs to be replaced frequently, and the daily maintenance cost of the equipment will increase. In addition, the noise is obvious when the scraper is in action, and the sealing of the connection needs to be improved. Utility Model Content

[0006] In order to solve the above problems, the utility model provides an ingeniously designed window system for CNC equipment, which removes cutting fluid, metal chips and stains on the perspective window plate through centrifugal force. The perspective window plate has high clarity, good water tightness, stable operation, low noise and long equipment service life.

[0007] According to one aspect of the utility model, a window system for numerical control equipment is provided, which is used as a viewport for observing the internal processing process in the numerical control equipment.

The ring cover is a hollow annular structure. One end of the driving component is fixed to the base, and the other end of the driving component is connected to the perspective window plate. The driving component drives the ring cover and the perspective window plate to rotate relative to the base. The perspective window plate is made of transparent material and is located on the inner side of the safety door. Thus, the driving component drives the ring cover and the perspective window plate to rotate, and the centrifugal force generated by the rotation is used to throw away the cutting fluid, metal chips, and stains on the perspective window plate, so as to achieve the effect of automatically removing the cutting fluid, metal chips, and stains. The perspective window plate has high clarity, so as to achieve the purpose of clearly observing the production process through the perspective window plate.

[0008] In some embodiments, the driving assembly includes a motor, a connector and a cap, the base has a bracket extending inward, the motor is mounted on the bracket, the output end of the motor is connected to one end of the connector, a through hole is provided at the center of the perspective window plate, the other end of the connector is embedded in the through hole of the perspective window plate, the end of the connector exposed from the through hole is connected to the cap, and the cap and the connector fix the perspective window plate. Therefore, the motor is selected as the power source, which has low noise, stable operation and long service life. The motor drives the perspective window plate, the ring cover and the cap to rotate through the connector. The motor is located outside the safety door, and its working environment is not disturbed by cutting fluid, metal chips, stains, etc., which is conducive to protecting the motor. The cap covers the through hole connection of the perspective window plate to prevent liquid and other impurities from entering, which is conducive to extending the service life of the equipment.

[0009] In some embodiments, a circuit channel for the power supply machine is provided in the bracket, and the lead wire of the motor is led out from the circuit channel. Thus, the wiring of the motor is sealed, which is conducive to extending the service life of the device.

[0010] In some embodiments, the connection between the cap and the connector adopts a left-handed thread locking structure. Therefore, during the rotation process, the left-handed thread locking structure can play a self-locking role, effectively achieving the function of fixing the perspective window plate and the ring cover, while also improving safety.

[0011] In some embodiments, the perspective window plate is transparent glass. Therefore, the transparent glass has a good visual effect and is not easily scratched by metal chips.

[0012] In some embodiments, the ring cover wraps around the edge of the perspective window panel by turning up the edge, and the edge of the perspective window panel is engaged with the ring cover. Therefore, the ring cover is made of aluminum alloy material, and when the perspective window panel and the ring cover are installed, the perspective window panel is put in through the extrusion process, and then rotated and extruded, so that the ring cover made of aluminum alloy can hold the edge of the perspective window panel, and the connection between the perspective window panel and the ring cover is watertight.

The edge of the perspective window plate is embedded in the ring cover through a flange, and the connection center of the perspective window plate is covered by a cap. The connection between the ring cover and the base is through a plurality of serrated waterproof labyrinth grooves, which effectively prevent the cutting fluid, metal chips and stains from entering the interior of the window system during the rotation, thereby improving the water tightness of the equipment, and the equipment has a long service life, stable operation and low noise.
