[0036] Specifically, the air in the dust collecting drawer 702 is sucked out by the air pump 9, so that a vacuum is formed inside the dust collecting drawer 702, and negative pressure is generated on the surfaces of several groups of chip suction grooves 701 connected to the dust collecting drawer 702, so that debris is sucked into the dust collecting drawer 702. At the same time, negative pressure is also generated at the air inlet end of the telescopic hose 11 connected to the dust collecting drawer 702, so that debris is sucked into the dust collecting drawer 702.

[0037] The clamping mechanism 8 includes a fixed plate 801 and a plurality of groups of movable clamping blocks 803; illustratively, Figure 3 shown.

[0038] The fixed plate 801 is fixedly connected to the top of the outer wall of the dust box 7, and a plurality of groups of chip leakage grooves 802 are formed on the fixed plate 801.

[0040] Specifically, by extending or contracting the output end of the electric cylinder 804, the distance between the movable clamping block 803 and the fixed plate 801 is adjusted, so that the clamping mechanism 8 can clamp and limit mechanical parts of different sizes. At the same time, through the coordinated use of several groups of electric cylinders 804, the position of the mechanical parts can be adjusted within a certain range, so as to adjust the position of the drilling holes on the surface of the mechanical parts according to the processing requirements.

[0041] The processing assembly 6 includes a mounting block 601; illustratively, as Figure 4-6 shown.

[0042] The mounting block 601 is fixedly connected to the slider 5, and a motor 602 is fixedly connected to the mounting block 601. The output end of the motor 602 passes through the mounting block 601 and is connected to a driving pulley 603. The bottom end of the mounting block 601 is rotatably connected to a driven pulley 604. Both the driven pulley 604 and the driving pulley 603 are sleeved with a synchronous belt 605.

[0043] The mounting block 601 is threadedly connected with a threaded rod 606, the top of the threaded rod 606 is fixedly connected with a first limit block 608, the bottom of the threaded rod 606 is installed with a drill bit 607, and the drill bit 607 is provided with a thread groove;

[0044] The mounting block 601 is slidably connected with a sliding shaft 609, the top of the sliding shaft 609 is fixedly connected with a second limit block 6010, a linkage rod 6011 is provided between the second limit block 6010 and the first limit block 608, one end of the linkage rod 6011 is rotatably connected to the first limit block 608, and the other end of the linkage rod 6011 is fixedly connected to the second limit block 6010;

[0045] The sliding shaft 609 is sleeved with a spring 6012, and the mounting block 601 is mounted with a pressure sensor 6013. One end of the spring 6012 contacts the bottom end of the second limit block 6010, and the other end of the spring 6012 contacts the upper surface of the pressure sensor 6013.

[0046] The bottom end of the sliding shaft 609 is fixedly connected to a mounting frame 6015, and the mounting frame 6015 is fixedly connected to a chip suction pipe 6016, the air inlet end of the chip suction pipe 6016 faces the processing end of the drill bit 607, and the other end of the chip suction pipe 6016 is connected to one end of the telescopic hose 11;

[0047] The driven pulley 604 is fixedly connected with a plurality of clamping blocks 6041, the bottom end of the mounting block 601 is provided with a clamping ring groove 6014, the clamping ring groove 6014 is movably fitted with the clamping block 6041, the driven pulley 604 is provided with a through hole 6042, the through hole 6042 is movably fitted with the threaded rod 606, the inner wall of the through hole 6042 is fixedly connected with a linkage bolt 6043, the threaded rod 606 is provided with a transmission groove 6061, the transmission groove 6061 is movably fitted with the linkage bolt 6043;

[0048] Specifically, the motor 602 drives the active pulley 603 to rotate, and the synchronous belt 605 drives the driven pulley 604 to rotate synchronously, so that the linkage bolt 6043 drives the threaded rod 606 to rotate synchronously. Since the threaded rod 606 is threadedly connected to the mounting block 601, the threaded rod 606 rotates and moves up and down. When drilling, the motor 602 drives the active pulley 603 to rotate forward, so that the driven pulley drives the threaded rod 606 to rotate forward and move downward, thereby driving the drill bit 607 to rotate and move downward while drilling. After the drilling operation is completed, the motor 602 drives the active pulley 603 to rotate in the opposite direction, so that the drill bit 607 rotates in the opposite direction and moves upward, and the debris is taken out through the threaded groove on the surface of the drill bit 607. The debris generated during the processing and the debris remaining on the drill bit 607 are sucked into the telescopic hose 11 through the chip suction pipe 6016 and then enter the dust collection drawer 702;

[0049] Furthermore, while the threaded rod 606 drives the drill bit 607 to move downward and rotate to drill, the linkage rod 6011 drives the second limit block 6010 to move downward, squeezing the spring 6012. The change in the pressure value of the pressure sensor 6013 is used to monitor the distance that the drill bit 607 descends. When the drilling depth reaches a preset value, the motor 602 is automatically controlled to reverse, so that the drill bit 607 rotates in the opposite direction and rises and resets at the same time, so that the drilling depth reaches the preset value.

[0050] The working principle of the processing device for producing mechanical parts proposed by the present invention is as follows:

[0051] By extending or contracting the output end of the electric cylinder 804, the distance between the movable clamping block 803 and the fixed plate 801 is adjusted, so that the clamping mechanism 8 can clamp and limit mechanical parts of different sizes. At the same time, through the coordinated use of several groups of electric cylinders 804, the position of the mechanical parts can be adjusted within a certain range, so as to adjust the position of the drilling holes on the surface of the mechanical parts according to the processing requirements.

[0052] The slider 5 is driven to move horizontally by the electric slide 4, so as to adjust the horizontal position of the processing component 6. The active pulley 603 is driven to rotate by the motor 602, and the driven pulley 604 is driven to rotate synchronously by the synchronous belt 605, so that the linkage bolt 6043 drives the threaded rod 606 to rotate synchronously. Since the threaded rod 606 is threadedly connected to the mounting block 601, the threaded rod 606 rotates and moves up and down. When drilling, the active pulley 603 is driven to rotate forward by the motor 602, so that the driven pulley drives the threaded rod 606 to rotate forward and move downward, thereby driving the drill bit 607 to rotate and move downward while drilling. After the drilling operation is completed, the active pulley 603 is driven to rotate in the opposite direction by the motor 602, so that the drill bit 607 rotates in the opposite direction and moves upward, and the debris is brought out through the threaded groove on the surface of the drill bit 607.

[0053] The air in the dust collecting drawer 702 is sucked out by the air pump 9, so that a vacuum is formed inside the dust collecting drawer 702, and negative pressure is generated on the surfaces of several groups of chip suction grooves 701 connected to the dust collecting drawer 702, so that debris is sucked into the dust collecting drawer 702. At the same time, negative pressure is also generated at the air inlet end of the telescopic hose 11 connected to the dust collecting drawer 702, and the debris generated during the processing and the debris remaining on the drill bit 607 are sucked into the telescopic hose 11 through the chip suction pipe 6016 and then enter the dust collecting drawer 702.

[0054] While the threaded rod 606 drives the drill bit 607 to move downward and rotate to drill, the linkage rod 6011 drives the second limit block 6010 to move downward to squeeze the spring 6012, and the change in the pressure value of the pressure sensor 6013 is used to monitor the descending distance of the drill bit 607. When the pressure value reaches the preset threshold, the motor 602 is triggered to rotate in the opposite direction, that is, when the drilling depth reaches the preset value, the motor 602 is automatically controlled to reverse, so that the drill bit 607 rotates in the opposite direction and rises and resets at the same time, so that the drilling depth reaches the preset value, thereby realizing the monitoring and adjustment of the drilling depth.

[0055] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein; and these modifications or substitutions do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
