Description

Technical Field

[0001] This invention relates to the field of CNC machine tools, and in particular to a machine tool front sliding door system and a CNC machine tool with anti-leakage and anti-jamming functions. Background Technology

[0002] A CNC machine tool is a modern machining equipment that precisely manipulates the movement of a machine tool through digital control commands. Using pre-programmed computer programs, it performs high-precision, high-efficiency cutting, drilling, milling, and other machining operations on workpieces made of metals, plastics, and composite materials. It is a core foundation of intelligent manufacturing and high-end equipment manufacturing.

[0003] The sliding door in front of a CNC machine tool is usually called a protective sliding door or safety door, and it is mostly a left-right sliding type. It mainly consists of the door body, transparent observation window, guide rails / rollers, handle, sealing strip, and safety interlock switch.

[0004] The main functions of closing the sliding door during processing are:

[0005] Safety isolation: to prevent personnel from accidentally touching high-speed rotating spindles, cutting tools, workpieces, etc.

[0006] Splash prevention: Keep chips, coolant, and oil mist inside the machine tool protective cover to keep the work area clean.

[0007] Sound insulation and noise reduction: Reduce processing noise.

[0008] Easy to observe: The processing status of the cutting tools and workpieces can be viewed through the observation window without opening the door.

[0009] The key point is the safety interlock: if the door is not closed properly, the machine tool usually cannot start the cycle; if the door is opened during processing, the spindle, feed, coolant, etc. will stop or pause and trigger an alarm. Automatic doors are driven by cylinders or motors.

[0010] Existing technologies for CNC machine tool sliding doors suffer from drawbacks such as easy leakage, easy jamming, and lack of active maintenance functions. Summary of the Invention

[0011] The technical problem to be solved by the present invention is to overcome the defects of existing CNC machine tool sliding doors, such as easy leakage, easy jamming, and lack of active maintenance functions, and to provide a machine tool sliding door system and CNC machine tool with active anti-leakage and anti-jamming functions to improve processing safety.

[0012] The present invention solves the above-mentioned technical problems through the following technical solution:

The optical axis is fixed to the inner side of the L-shaped baffle. A baffle strip is provided below the flow guide plate of the left sliding door and the right sliding door. The baffle strip and the L-shaped baffle form the flow guide groove.

[0018] Preferably, both the left and right sliding doors are equipped with sliding modules at their bottoms. The sliding module includes a small bearing positioning rod, a small deep groove ball bearing, a large bearing positioning rod, a front sliding door lower support connecting plate, and a large bearing.

The small deep groove ball bearing is installed below the optical axis via the small bearing positioning rod fixed to the front sliding door lower support connecting plate. The large bearing is installed above the optical axis via the large bearing positioning rod fixed to the front sliding door lower support connecting plate.

[0019] Preferably, the top slide rail is an optical axis, and the tops of the left and right sliding doors are mounted on the optical axis of the top slide rail by sliders. An electromagnetic ball lock is provided at the top mating position of the left and right sliding doors, and the processing module is used to receive the locking signal sent by the electromagnetic ball lock.

[0020] Preferably, the processing module is used to determine whether the air pressure signal is greater than a preset value. If so, it controls the cylinder reversing valve to drive the cylinder to perform a reverse retraction and forward movement obstacle clearing step.

[0021] Preferably, the left-hand or right-hand sliding door is equipped with a visual monitoring mechanism and a rotating viewing window mechanism.

[0022] Preferably, the visual monitoring mechanism is used to acquire an image of the calibration structure of the processing area after the processing module receives the door lock signal. The processing module is used to determine whether the current image matches the image of the calibration structure. If not, it controls the cylinder reversing valve to drive the cylinder to perform a reverse retraction and forward movement obstacle clearing step.

[0023] Preferably, the processing module is used to acquire the door lock signal, the image of the calibration structure, and the air pressure signal; the processing module is also used to:

[0024] Determine whether the locked door signal, the image of the calibration structure, and the air pressure signal all meet preset conditions. If so, execute the CNC machine tool processing. The preset condition for the locked door signal is that it is in a locked state.

The preset condition for the image of the calibration structure is that the current image matches the image of the calibration structure, provided that the image of the calibration structure meets the clarity requirements.

[0025] Preferably, the processing module is further configured to obtain the blur of the current image using blur detection technology, obtain the image blur by using a vision monitoring mechanism during CNC machine tool processing to obtain evaluation data of the processing environment, generate a correction value for dynamically adjusting the processing feed speed based on the evaluation data, and use the correction value to dynamically adjust the processing feed speed.

[0026] The processing module is also used to obtain the opening speed of the left and right sliding doors by using the blurriness of the images obtained by the visual monitoring mechanism during a preset time period before the doors open.
