[0053] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0054] Please see Figures 1-7 As shown, the present invention is an intelligent gantry machining center, including a machining table 1 and a controller. Automatic slide rails are provided on both sides of the machining table 1, and a gantry frame 2 is installed on the automatic slide rails. The gantry frame 2 includes two columns and a middle crossbeam. A machining die head 3 is provided on the middle crossbeam. A circulation pipe 4 is embedded in the columns and the middle crossbeam. A cleaning mechanism 5 is provided on the machining table 1, which is used to clean the debris on the machining table 1.

[0055] In this embodiment, by embedding circulation pipes 4 in the two columns and the middle crossbeam, and connecting circulation pumps to the outside of the circulation pipes 4, air circulation can be achieved inside the two columns and the middle crossbeam, so that the temperature of the left and right columns tends to be consistent, eliminating the temperature difference between the two sides caused by sunlight, air conditioning and other reasons, and improving the thermal stability of the gantry machining center; and the cleaning mechanism 5 thoroughly cleans the machining debris on the machining table 1, minimizing the adverse effects of machining debris.

[0056] The cleaning mechanism 5 includes: a control module, a cleaning component 51, and an air blowing component 52. The cleaning component 51 includes:

[0057] Lead screw 511, which is rotatably mounted on one side of the processing table 1;

[0058] A light rod 512 is fixedly installed on the other opposite side of the processing table 1;

[0059] A drive motor 513 is mounted on the processing table 1 and is connected to the lead screw 511 in a transmission manner.

[0060] A slider seat 514 is sleeved on the lead screw 511 and the guide rod 512, and the slider seat 514 and the lead screw 511 are connected by a helical transmission.

[0061] The top of the sweeping frame 515 is connected to the slider seat 514 via an electric telescopic rod 516.

[0062] Brush layer 517, which is detachably fixed to the bottom of the sweeping frame 515;

[0063] A protective shell is fitted onto the lead screw 511, and an opening groove is provided on one side of the protective shell for the slider seat 514 to move.

[0064] The air blowing assembly 52 includes:

[0065] The air blowing frame 521 is horizontally arranged below the processing table 1;

[0066] The air blowing frame 521 is slidably mounted on the stand 522;

[0067] A multi-section automatic telescopic column 523 is provided with one end fixedly installed on one side of the bottom of the processing table 1, and the other end is detachably and fixedly connected to the air blowing frame 521.

[0068] An air pump 524 is located on one side of the processing table 1 and supplies air to the air nozzles 526 through a telescopic hose 525. Multiple air nozzles 526 are embedded in the top of the air blowing frame 521 and are arranged at equal intervals along the lateral direction.

[0069] A pressure sensor is installed inside the telescopic hose 525.

[0070] In this embodiment, by setting the lower air blowing component 52 and the upper cleaning component 51 in cooperation, the goal of thoroughly removing debris from the processing table 1 can be achieved. The specific working process is as follows: after the workpiece is processed, the drive motor 513 drives the lead screw 511 to rotate. The lead screw 511 and the slider seat 514 are screwed together, causing the cleaning frame 515 and the bristle layer 517 on the slider seat 514 to move back and forth, thereby cleaning the debris on the processing table 1, and then returning to the initial position to wait for the next cleaning action. At the same time, the lower air blowing pump 524 is started, and air is supplied to each air nozzle through the telescopic hose 525. The air nozzle is set one by one with the drain hole on the processing table 1. Under the push of the multi-section automatic telescopic rod, the drain hole is pressurized and impacted, forcibly blowing out the debris in the drain hole, which is then swept away by the following cleaning component 51. The two work together to achieve a relatively thorough debris removal effect.

[0071] The bristle layer 517 includes an inner layer 8 and an outer layer. The outer layer can slide circumferentially along the outer surface of the inner layer 8. The outer layer is configured with stiff bristles, and the inner layer 8 is configured with soft bristles. The outer layer has two layers: a first surrounding layer 9 and a second surrounding layer 10. The second surrounding layer 10 is located on the outermost side. The top height of the first surrounding layer 9 is greater than the top height of the second surrounding layer 10. A toothed band 11 is fixed to the outer side of the top of the first surrounding layer 9, and a toothed band 12 is fixed to the outer side of the top of the second surrounding layer 10. A toothed rack 13 is provided on one side of the protective shell, and a toothed rack 14 is provided on the other side of the protective shell. The toothed rack 13 engages with the toothed band 11, and the toothed rack 14 engages with the toothed band 12. 12. Engagement: When the bristle layer 517 moves, the first toothed strip 13 and the second toothed strip 14 remain stationary, while the first toothed belt 11 and the second toothed belt 12 move, thus passively rubbing the first toothed belt 11 and the second toothed belt 12 in a circumferential rotation. Since the two outer layers move towards the same side simultaneously, under the rubbing action of their respective toothed strips, the two outer layers rotate in opposite directions in a circumferential rotation. On the one hand, this creates an effect of alternating rubbing of surface impurities, which, combined with the soft bristles in the middle, achieves a stronger cleaning effect. On the other hand, the hard bristles on the outer layers always come into contact with stubborn impurities first, which can pre-clean up the stubborn impurities. At the same time, during the alternating rubbing process of the two layers of hard bristles, large impurities will also be rubbed and broken down one after another, thereby reducing the entrainment of large impurities and always maintaining the efficient cleaning of the bristles.

[0072] The air blowing frame 521 is configured as a concave structure with a recessed center on the top surface. The edge of the upper surface of the air blowing frame 521 is in contact with the bottom surface of the processing table 1. A sealing component 53 is also provided on the surface of the air blowing frame. The sealing component 53 is used to seal the upper surface of the air blowing frame and the bottom surface of the processing table 1, and at the same time to intermittently lubricate the lead screw 511.

[0073] The sealing assembly 53 includes an embedding groove 531, which is formed around the outer side of the upper surface of the air blower 521. An elastic sealing airbag 532 is embedded and fixed in the embedding groove 531. The embedding groove 531 is filled with lubricating oil. An oil outlet pipe 533 is provided on the side of the embedding groove 531 facing the lead screw 511. A one-way valve 534 is provided in the oil outlet pipe 533. A displacement groove 535 is provided on the side of the processing table 1 facing the oil outlet pipe 533, so that the lubricating oil sprayed from the oil outlet pipe 533 can directly contact the surface of the lead screw 511. An arc-shaped protrusion 536 is provided on the bottom surface of the processing table 1. The arc-shaped protrusion 536 is located on the travel path of the elastic sealing airbag 532. An oil replenishment pipe 537 is connected to the other side of the embedding groove 531. A one-way oil inlet valve 538 is provided in the oil replenishment pipe 537.

[0074] In this embodiment, to prevent the gas ejected from the nozzle from overflowing and being wasted, a sealing component 53 is added to the air blowing frame 521. During use, oil is added to the oil supply pipe 537 via an external oiling device. After the lubricating oil in the embedded groove 531 is full, the bottom of the elastic sealing airbag 532 is compressed, causing the top to bulge out. This allows it to press against the bottom surface of the processing table 1. The surrounding elastic sealing airbag 532 achieves a sealing action inside the air blowing frame 521, effectively ensuring the effective use of the pressurized air blower 524 and improving the leakage rate. The internal debris removal effect is achieved by the elastic sealing airbag 532 meeting the arc-shaped protrusion 536 on the bottom surface of the processing table 1 during the displacement of the air blower 521. Under the passive compression of the left side of the elastic sealing airbag 532 by the arc-shaped protrusion 536, the elastic sealing airbag 532 contracts downward, thereby forcibly compressing the lubricating oil embedded in the groove 531 to spray out from the oil outlet pipe 533. Since the can opening of the oil outlet pipe 533 corresponds to the lead screw 511, the lubricating oil will be sprayed onto the lead screw 511. Subsequently, the slider seat 514 will make transmission contact with the lubricated area to achieve the effect of automatic lubrication.

[0075] By setting the sealing component 53, this invention can, on the one hand, utilize the sealing characteristics of the elastic sealing airbag 532 to achieve a sealing effect on the edge of the air blowing frame 521, thereby preventing gas from overflowing from the air blowing nozzle 526 and enabling effective utilization of the gas from the air blowing pump 524; on the other hand, by using the arc-shaped protrusion 536 set at the bottom of the processing table 1 in conjunction with the elastic sealing airbag 532, intermittently extruding lubricating oil is achieved, thereby achieving the function of automatically lubricating the lead screw 511 and the slider seat 514 transmission; at the same time, since the lubricating oil is sprayed downwards towards the lead screw 511, the workpiece processing phase above is isolated, avoiding damage caused by debris entering the transmission part during the lubrication process.

[0076] A guide plate 6 is rotatably connected to the bottom of the slider seat 514. The guide plate 6 is configured in an L-shape. An angle sensor is installed between the guide plate 6 and the sweeping frame 515. The included angle between the guide plate 6 and the sweeping frame 515 is adjusted by a movable adjusting telescopic rod 7. The inner angle of the guide plate 6 is set with an arc transition. A rangefinder is installed inside the adjusting telescopic rod 7 to detect the extension of the adjusting telescopic rod 7 in real time. The adjusting telescopic rod is an electric telescopic rod.

[0077] In this embodiment, by setting the baffle 6, the air pressure of the air pump 524 can be increased to force the mixture out of the leak hole when the cutting fluid and chips solidify at low temperature or mix, causing severe blockage. Simultaneously, the electric adjusting telescopic rod 7 is extended to widen the angle between the baffle 6 and the cleaning frame 515, guiding the mixture along the baffle 6 to a more distant surface of the machining table 1. This prevents the mixture from falling back into the leak hole due to an insufficient angle between the baffle 6 and the cleaning frame 515. When the situation occurs, the present invention, through the L-shaped structure of the guide plate, provides a shield above the drain hole when the air blowing assembly 52 is working, preventing debris from flying around and causing subsequent cleaning problems when it is forcibly blown out from bottom to top. At the same time, it can also adapt the included angle of the guide plate 6 to the mixed clumps and the enhanced gas impact force, thereby guiding the mixed clumps. By using the airflow blown out from other drain holes, the mixed clumps at a distance are impacted, thereby dispersing the mixed clumps and facilitating the cleaning action of the subsequent cleaning assembly 51.

[0078] The control module includes:

[0079] A drive unit, which is electrically connected to the controller, is used to control the operation of the drive motor 513 and the air pump 524;

[0080] A storage unit, electrically connected to the controller, is used to store relevant data and programs;

[0081] The data acquisition unit is used to collect the gas pressure value inside the telescopic hose 525 and the angle value between the baffle 6 and the cleaning frame 515 in real time.

[0082] An execution unit, electrically connected to the controller, is used to execute the program in the storage unit.

[0083] The control module operates as follows:

[0084] Based on the real-time acquisition of the gas pressure value P inside the telescopic hose 525 by the pressure sensor 实 ;

[0085] Based on historical statistical data, a pre-set gas pressure threshold P for leak-blocked conditions is established. 阈 ;

[0086] The real-time detected gas pressure value P 实 With gas pressure threshold P 阈 Perform a comparison; if P 实 -P 阈 If ≥0, then the horizontal row of leaks here is considered to be blocked;

[0087] The angle value γ between the guide plate 6 and the sweeper 515 is collected in real time based on the angle sensor. i ; through the following formula:

[0088] γ0=α*(P 实 -P 阈 )+γ i (1)

[0089] The angle γ0 between the adjusted guide baffle 6 and the cleaning frame 515 is calculated, where α is the adjustment parameter, selected and determined based on experimental data; the execution unit calculates the current gas pressure value P. 实 With gas pressure threshold P 阈 The difference is used to adjust the included angle between the guide baffle 6 and the sweeper frame 515;

[0090] Substitute γ0 into the following equation:

[0091] γ0=β*L; (2)

[0092] The elongation length L of the adjusting telescopic rod 7 is calculated, where β is a preset proportional coefficient, which is selected and determined based on empirical data;

[0093] The actuator controls the extension rod 7 to length L.

[0094] In this embodiment, a specific method for the control module is provided. By real-time acquisition of the gas pressure in the telescopic hose 525 supplied by the air pump 524 and the angle between the baffle 6 and the cleaning frame 515, and by judging the blockage status of the current horizontal row of leaks by the current gas pressure, it is possible to prevent the situation where the same power of the air pump 524 is always used due to severe blockage of the leaks, resulting in incomplete cleaning of debris from the leaks. The angle between the baffle 6 and the cleaning frame 515 is adjusted in real-time according to the difference between the current gas pressure value and the gas pressure threshold. This also prevents the mixed material from falling back into the leaks after the power is increased, thus avoiding potential debris cleaning hazards.

[0095] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
