[0017] 1. The processing unit in the drilling and cutting machine of the present application includes an upper machine head and a lower machine head, and the upper machine head and the lower machine head perform drilling and cutting processing on the material from the top and bottom of the material respectively, thereby improving the processing efficiency of the material; in addition, by setting a Y-direction drive module, the lower machine head can be driven to move along the Y direction, thereby realizing accurate locking of the relative position of the lower machine head and the material, and helping to improve the processing accuracy and processing efficiency of the material by the lower machine head; the lower machine head of the present application is also provided with a dust hood, and when the drill group and the spindle group in the lower machine head generate debris during the process of drilling or grooving the material, the dust hood can, on the one hand, absorb the debris generated by the drill group and the spindle group during operation, and the material debris absorbed by the dust suction port They are discharged after passing through the dust removal channel and the dust outlet in sequence, which reduces the possibility of material debris being ejected to other components, thereby reducing the impact of the debris on the normal operation of the drilling and cutting machine and providing a guarantee for the stable operation of the drilling and cutting machine. On the other hand, since the debris is generated at the contact position between the main shaft and the material and the contact position between the drill bit and the material, and the kinetic energy of the debris is relatively strong when it is just generated, the dust suction port is set to surround the main shaft and the drill bit, which can shield the debris with strong kinetic energy. After the debris collides with the dust hood, the kinetic energy of the debris is greatly dissipated, and it can be more easily sucked into the dust suction port, which improves the dust hood's efficiency in absorbing the debris and reduces the possibility of the debris being unable to be absorbed by the dust hood due to excessive kinetic energy.

When the spindle is cutting, the elastic sheet abuts against the spindle under the action of its own elastic force, thereby sealing the gap between the spindle and the side wall of the first through hole, preventing debris from escaping from the dust suction port through the gap between the first through hole and the spindle, thereby improving the dust suction efficiency of the dust suction port for debris collection, and helping to improve the dust suction performance of the dust suction hood.

[0019] 3. As a preferred embodiment of the present application, a positioning piece is provided, and the elastic piece is fixed to the inner wall of the dust hood by means of the positioning piece and the dust hood being pressed together, so that the fixing method of the elastic piece and the dust hood is a surface connection. Compared with the fixing method of the elastic piece and the dust hood being connected at points, the fixing method of the surface connection can improve the locking property of the elastic piece and the dust hood, and reduce the possibility of stress concentration at the contact position between the elastic piece and the dust hood, thereby reducing the possibility of wear and damage of the elastic piece at the connection position with the dust hood during long-term use, which helps to improve the service life of the elastic piece; in addition, the positioning piece and the dust hood are threadedly locked with threaded fasteners, and the detachable connection between the positioning piece and the dust hood is achieved while ensuring the connection strength between the two.

[0020] 4.

The setting of the Z-direction slide also improves the driving smoothness of the Z-direction drive module, helps to improve the movement efficiency of the lower machine head, and realizes the rapid locking of the material drilling and cutting position.

[0022] 6. As a preferred embodiment of the present application, a first guide rail and slider mechanism including a first slider and a first guide rail is provided, so that the Z-axis slider can move stably under the driving action of the first slider and the first guide rail, and the cylinder is fixed to the mounting plate.

[0058] like Figures 1 to 6 As shown, a drilling and cutting machine includes a frame 1 and a processing unit, the frame 1 has a loading platform 2 for placing materials, the processing unit is used for drilling and cutting the materials to be processed placed on the loading platform 2, the processing unit includes an upper crossbeam 3, a lower crossbeam 4, a Y-direction drive module, an upper head 6 and a lower head 7, the upper head 6 is arranged on the upper crossbeam 3, the Y-direction drive module can drive the lower head 7 to move along the lower crossbeam 4, the lower head 7 includes a spindle group, a drill group and a dust hood 5, the spindle group includes a spindle 9, the drill group includes a drill 10 motor and a drill 10 driven by the drill 10 motor, the dust hood 5 has a dust suction port 11, a dust outlet 12 and a dust removal channel connecting the dust suction port 11 with the dust outlet 12, the spindle 9 and the drill 10 are surrounded by the dust hood 5 in the dust suction port 11.

[0059] The processing unit in the drilling and cutting machine of the present application includes an upper head 6 and a lower head 7, and the upper head 6 and the lower head 7 perform drilling and cutting processing on the material from the top and bottom of the material respectively, thereby improving the processing efficiency of the material; in addition, by setting up a Y-direction driving module, the lower head 7 can be driven to move along the Y direction, so as to realize accurate locking of the relative position of the lower head 7 and the material, thereby helping to improve the processing accuracy and processing efficiency of the material by the lower head 7; the lower head 7 of the present application is also provided with a dust hood 5, and when the drill group and the spindle group in the lower head 7 generate debris during the process of drilling or grooving the material, the dust hood 5 can, on the one hand, absorb the debris generated by the drill group and the spindle group during operation, and the material debris absorbed by the dust suction port 11 is successively discharged. After being discharged through the dust removal channel and the dust outlet 12, the debris is discharged, which reduces the possibility of material debris being ejected to other components, thereby reducing the impact of the debris on the normal operation of the drilling and cutting machine, and providing a guarantee for the stable operation of the drilling and cutting machine; on the other hand, since the debris is generated at the contact position between the main shaft 9 and the material and the contact position between the drill 10 and the material, and the kinetic energy of the debris is relatively strong when it is just generated, the dust suction port 11 is set to surround the main shaft 9 and the drill 10, which can shield the debris with strong kinetic energy. After the debris collides with the dust hood 5, the kinetic energy of the debris is greatly dissipated, and it can be more easily sucked into the dust suction port 11, which improves the dust hood 5's efficiency in absorbing the debris and reduces the possibility that the debris cannot be absorbed by the dust hood 5 due to excessive kinetic energy.

[0060] Figure 3 The Y-axis driving module is schematically shown in FIG. Figure 3 The double-headed arrow Y in the middle indicates the movement direction of the Y-direction drive module, which can reciprocate along the Y direction.

[0061] As a preferred embodiment of the present application, Figure 3 , Figure 5 , Figure 6As shown, the dust hood 5 is provided with a first through hole 13 penetrating the dust suction port 11, and the dust hood 5 is installed with an elastic sheet 14 covering the first through hole 13, and the elastic sheet 14 is provided with an expansion joint that can be closed or opened, so that the main shaft 9 passes through the expansion joint and enters the dust suction port 11. Since the spindle 9 needs to move towards and away from the material during operation, that is, the spindle 9 needs to move back and forth in the dust suction port 11, the present application provides a movement channel for the spindle 9 by setting a first through hole 13 and an elastic sheet 14, which is convenient for the spindle 9 to move close to or away from the material for cutting, and separates the spindle 9 from the drill 10 to avoid mutual interference between the two during operation, thereby providing a guarantee for the stable operation of the lower head 7; on the other hand, the elastic sheet 14 is provided with a closable or openable expansion joint. When the spindle 9 is cutting, the elastic sheet 14 abuts against the spindle 9 under the action of its own elastic force, thereby sealing the gap between the spindle 9 and the side wall of the first through hole 13, preventing debris from escaping from the dust suction port 11 through the gap between the first through hole 13 and the spindle 9, thereby improving the dust collection efficiency of the dust suction port 11 for debris, and helping to improve the dust suction performance of the dust suction hood 5.

[0062] Specifically, the elastic sheet 14 may be a structure made of rubber material.

[0063] As a preferred embodiment of this implementation, Figure 6 As shown, it also includes a positioning piece 15, the positioning piece 15 is provided with a first positioning hole, and the dust hood 5 is provided with a first threaded hole. The positioning piece 15 presses and fixes the elastic piece 14 on the inner wall of the dust hood 5 through the cooperation of a threaded fastener with the first positioning hole and the first threaded hole.

[0064] By setting a positioning piece 15, the elastic piece 14 is fixed to the inner wall of the dust hood 5 by the positioning piece 15 and the dust hood 5 being pressed together, so that the fixing method of the elastic piece 14 and the dust hood 5 is surface connection. Compared with the fixing method of the elastic piece 14 and the dust hood 5 being fixed by point connection, the fixing method of surface connection can improve the locking performance of the elastic piece 14 and the dust hood 5, and reduce the possibility of stress concentration at the contact position of the elastic piece 14 and the dust hood 5, thereby reducing the possibility of wear and damage of the elastic piece 14 at the connection position with the dust hood 5 during long-term use, which helps to improve the service life of the elastic piece 14; in addition, the positioning piece 15 and the dust hood 5 are threadedly locked by threaded fasteners, and the detachable connection between the positioning piece 15 and the dust hood 5 is achieved under the premise of ensuring the connection strength between the two. When the elastic piece 14 is aged, or it is necessary to replace the elastic piece 14 of different sizes to adapt to different types of spindles 9, it is convenient to replace the elastic piece 14 after the positioning piece 15 is removed from the dust hood 5, thereby reducing the difficulty of replacing the elastic piece 14.

[0065] The present embodiment does not limit the number and position of the first positioning holes and the first threaded holes, which should be adaptively adjusted according to the structural forms of the elastic sheet 14 and the positioning sheet 15. For example, in one example, the elastic sheet 14 is a circular structure, and the positioning sheet 15 can also be set to a circular shape that matches the shape of the elastic sheet 14, and a plurality of first positioning holes are spaced apart along the circumferential direction of the positioning sheet 15; in another example, the elastic sheet 14 is Figure 6 The rectangular structure shown in FIG. 1 , the positioning sheet 15 can also be set as a rectangular structure that matches the shape of the elastic sheet 14 , and the number of the first positioning holes is set to four, and the four first positioning holes are respectively set at the four corners of the positioning sheet 15 .

By providing the second through hole 16 in the dust cover 5, a working space is provided for the drill 10, and the drill 10 is separated from the spindle 9 to avoid mutual interference between the two when working, thereby providing a guarantee for the stable operation of the lower machine head 7; in addition, the edge of the second through hole 16 is in contact with the shell of the drill group, thereby avoiding the existence of a gap between the drill group and the second through hole 16, thereby avoiding the possibility of debris escaping from the gap to the dust suction port 11, which helps to improve the dust collection efficiency of the dust cover 5.

[0068] Such a configuration improves the connection stability between the drilling group and the dust hood 5. Since the dust hood 5 may be affected by the airflow and vibrate when performing vacuuming, the dust hood 5 is fixed to the outer shell of the drilling group so that the vibration of the dust hood 5 can be borne by the drilling group, thereby increasing the working stability of the dust hood 5. In addition, the dust hood 5 and the drilling group are detachably connected by a first fastener, which is convenient for the staff to clean the dust hood 5 after removing it from the drilling group, thereby reducing the cleaning pressure of the dust hood 5.

By setting the Y-direction slide 17 and the Z-direction slide 18, on the one hand, the Y-direction slide 17 cooperates with the lower horizontal sliding and moves along the lower cross beam 4 under the push of the Y-direction active module, thereby improving the movement smoothness of the Y-direction slide 17; similarly, the Z-direction drive module can drive the Z-direction slide 18 to move along the Y-direction slide 17, so that the spindle group and the drilling group change their positions along the Z direction under the drive of the Z-direction slide 18, that is, the working stroke of the spindle group and the drilling group along the Z direction is increased. The setting of the Z-direction slide 18 also improves the driving smoothness of the Z-direction drive module, helps to improve the movement efficiency of the lower machine head 7, and realizes the rapid locking of the material drilling position.

By providing the mounting plate 20, a mounting position is provided for the spindle 9, and the cylinder 8 drives the spindle 9 to move by pushing the mounting plate 20 to move up and down along the Z-direction slide plate 18, thereby increasing the movement stability of the spindle 9.

The piston rod of the cylinder 8 drives the relative movement of the slider and the mounting plate 20 during the movement, and the first guide rail and the first slider can guide the movement direction of the slider to avoid the slider from being displaced during the movement relative to the mounting plate 20, thereby providing a guarantee for the stable movement of the main shaft 9.

[0074] As another preferred embodiment of this implementation mode, Figure 3 , Figure 4 As shown, the Z-direction drive module includes a Z-direction drive motor 22 and a ball screw nut pair connected to the output shaft of the Z-direction drive motor 22, and the Z-direction drive motor 22 drives the Z-direction slide plate 18 to move along the Y-direction slide plate 17 through the ball screw nut pair; the Z-direction slide plate 18 and the Y-direction slide plate 17 are slidably connected through a second guide rail slider mechanism, and the second guide rail slider mechanism includes a second slider disposed on the Z-direction slide plate 18 and a second guide rail disposed on the Y-direction slide plate 17.

[0076] By setting the reducer 21, the output shaft speed of the Y-axis drive motor 19 can be reduced, and the output torque of the Y-axis drive motor 19 can be increased, so as to enhance the driving effect of the Y-axis drive motor 19 on the lower beam 4; in addition, by setting gears and racks at the output end of the reducer 21 and the upper beam 3, respectively, the lower beam 4 moves through the meshing transmission of the gears and the racks, thereby improving the travel stability of the lower beam 4, and after the lower beam 4 reaches the preset position, the reducer 21 is stopped by controlling the Y-axis drive motor 19, the gears will stop rotating immediately, and the gears and the racks will be stuck to prevent the lower beam 4 from moving. The lower cross beam 4 is stopped from moving, which improves the real-time performance of the movement or stopping of the lower cross beam 4 and reduces the possibility of inaccurate positioning of the Y-axis slide 17 due to the inertia of movement; in addition, the Y-axis slide 17 is connected to the lower cross beam through a third guide rail slide mechanism including a third slide block and a third guide rail, which locks the motion trajectory of the Y-axis slide 17 and the lower cross beam 4 for relative movement, so that the Y-axis slide 17 can only move along the extension direction of the third guide rail, thereby improving the motion accuracy of the Y-axis slide 17, so as to improve the motion accuracy of the lower machine head 7 installed on the Z-axis slide 18 along the Y direction.
