The drilling mechanism 1 can pump water to cool down and rinse the workpiece drill bit while drilling, and then the rinse water and iron filings enter the filter mechanism 6 for filtration, so that the water can be recycled; The drilling mechanism 1 includes a protective shell 101, a flat plate 102 is fixedly mounted on the outer wall of the protective shell 101, a punching motor 103 is installed on the top of the protective shell 101, a liquid storage cylinder 115 is arranged on the top of the flat plate 102, a rubber plug 114 is slidably connected to the inner wall of the liquid storage cylinder 115, a moving rod 113 is fixedly mounted on the inner wall of the rubber plug 114, an inlet check valve 117 and an outlet check valve 119 are fixedly mounted on the outer wall of the liquid storage cylinder 115, an inlet pipe 118 is fixedly mounted on the outer wall of the inlet check valve 117, an outlet pipe 120 is fixedly mounted on the outer wall of the outlet check valve 119, a cooling pipe 121 is installed on the end of the outlet pipe 120 away from the outlet check valve 119, and a water supply pipe 122 is installed on the end of the cooling pipe 121 away from the outlet pipe 120; In the above structure, the rubber plug 114 is driven by the moving rod 113 to move in the direction of the punching motor 103 to form a suction force, at which time the water inlet check valve 117 is in an open state, and then the water enters the liquid storage cylinder 115 through the water inlet pipe 118 and the water inlet check valve 117. When the moving rod 113 and the liquid storage cylinder 115 move in the opposite direction to the punching motor 103, the rubber plug 114 pushes the water in the liquid storage cylinder 115, so that the water closes the water inlet check valve 117, and at the same time the water outlet check valve 119 is opened, so that the water passes through the water outlet pipe 120 and the cooling pipe 121 to reach the water supply pipe 122, and then the water is sprayed out through the water supply pipe 122, the water can cool the workpiece and the drill bit, and the water pressure is increased by using the squeezing force of the rubber plug 114, and the squeezed water can wash the iron filings; The filtering mechanism 6 includes a water tank 601, a water inlet pipe 118 passes through the water tank 601, a filter box 602 is provided on the right side of the water tank 601, a through groove 603 is provided between the filter box 602 and the water tank 601, and the through groove 603 is located at the top between the water tank 601 and the filter box 602, a filter element 607 is installed on the inner wall of the filter box 602, a filter bucket 604 is provided on the top of the water tank 601 and the filter box 602, a retaining bar 605 is installed at the bottom of the inner cavity of the filter bucket 604, and a vertical groove 606 is provided on the top of the filter bucket 604 and the filter box 602.

[0021] In the above structure, through the arrangement of the water tank 601 and the filter box 602, the mixture of water and iron filings will flow to the filter bucket 604 and the baffle 605. When the water and iron filings flow on the filter bucket 604, the baffle 605 can block the iron filings, so that the iron filings in the filter box 602 become less. Since the iron filings have weight, a large amount of iron filings are deposited at the bottom of the filter box 602. The iron filings are blocked by the filter element 607, so that water passes through the filter element 607, and then the water enters the water tank 601 through the through groove 603, so that the water used for flushing and cooling can be reused.

[0022] In a preferred embodiment: the power output shaft of the punching motor 103 is fixedly sleeved with a left small gear 104, the outer edge of the left small gear 104 is meshed with a left large gear 105, the top of the left large gear 105 is fixedly equipped with a right small gear 106, the outer edge of the right small gear 106 is meshed with a right large gear 107, the right small gear 106 and the inner wall of the left large gear 105 are fixedly sleeved with a connecting column 1061, the connecting column 1061 is movably connected to the protective shell 101, and the inner wall of the right large gear 107 is fixedly sleeved with a rotating column 108.

[0023] In the above structure, the left side large gear 105 is driven to rotate by the rotation of the left side small gear 104. At this time, the rotation speed of the left side large gear 105 is reduced. When the left side large gear 105 rotates, the right side small gear 106 rotates synchronously. The right side large gear 107 is driven to rotate by the rotation of the right side small gear 106, so that the rotation speed of the right side large gear 107 can be reduced again. When the right side large gear 107 rotates, it can drive the rotating column 108 to rotate.

[0024] In a preferred embodiment: a disc 109 is fixedly mounted on the top of the rotating column 108 , a column 110 is arranged on the periphery of the top of the disc 109 , a movable rod 111 is movably sleeved on the outer edge of the column 110 , and the movable rod 111 is movably connected to the moving rod 113 through a short column 112 .

[0025] In the above structure, the rotation of the rotating column 108 can drive the disc 109 to rotate, and the rotation of the disc 109 can cause the column 110 to rotate around the outer periphery of the rotating column 108. When the column 110 rotates, the movable rod 111 can be driven to move. When the movable rod 111 moves, it can drive the movable rod 113 and the rubber plug 114 to reciprocate in the liquid storage cylinder 115, so that the rubber plug 114 can extract and output water, thereby improving the rationality of the device.

[0026] In a preferred embodiment, a sealing cover 116 is installed on the outer wall of the liquid storage cylinder 115 at one end away from the water inlet check valve 117 , and the moving rod 113 is slidably connected to the sealing cover 116 .

[0027] In the above structure, by installing a sealing cover 116 on the outer wall of the liquid storage cylinder 115, the sealing cover 116 can be removed from the liquid storage cylinder 115, and the rubber plug 114 can be removed from the liquid storage cylinder 115, so that the inner cavity of the liquid storage cylinder 115 is easy to clean. The sealing cover 116 can limit the moving rod 113, and the connection between the moving rod 113 and the rubber plug 114 is more stable, thereby improving the stability of the device.

[0028] In a preferred embodiment, the cooling tube 121 is a threaded tube, and the cooling tube 121 is a stainless steel tube, and the cooling tube 121 is located at the periphery of the punching motor 103 .

[0029] In the above structure, through the setting of the cooling tube 121, when water enters the cooling tube 121, the water in the cooling tube 121 will absorb part of the heat emitted by the punching motor 103, so that the punching motor 103 can also be cooled by the cooling tube 121 under its own fan heat dissipation state, thereby greatly improving the service life of the punching motor 103.

[0030] In a preferred embodiment: a transverse groove 31 is formed on the outer wall of the equipment bin 3 , a bin door 32 is installed on the inner wall of the transverse groove 31 , and the filter bucket 604 is slidably connected to the transverse groove 31 .

[0031] In the above structure, through the setting of the transverse groove 31, when a large amount of iron filings are accumulated in the filter bucket 604, the compartment door 32 can be opened at this time, and then the filter bucket 604 can be pulled out from the transverse groove 31, and then the iron filings on the filter bucket 604 can be cleaned, so that the inner cavity of the filter bucket 604 is easy to clean.

[0032] In a preferred embodiment, a connecting tube 608 is fixedly mounted at the bottom of the vertical groove 606 , and the connecting tube 608 passes through the filter element 607 . The height of the filter element 607 is lower than that of the through groove 603 .

[0033] In the above structure, through the setting of the connecting tube 608, the water and iron filings on the filter bucket 604 can pass through the vertical groove 606 and then enter the filter box 602 through the connecting tube 608. The filter element 607 blocks the iron filings, so that the water will overflow the filter element 607, and then the water will enter the water tank 601 through the through groove 603.

[0034] In a preferred embodiment, the angle between the filter hopper 604 and the water tank 601 is 5°, and a plurality of baffles 605 are provided and evenly distributed on the filter hopper 604 .

[0035] In the above structure, by setting the filter bucket 604 to an inclined state, water can automatically flow toward the vertical groove 606. The flow of water drives the iron filings to flow. Larger iron filings will fall downward due to their own gravity. The iron filings are blocked by a number of baffles 605, so that the larger iron filings will not flow into the filter box 602. The large iron filings are filtered through the filter bucket 604.

[0036] In a preferred embodiment, the filter hopper 604 is located below the platform 5 , and the height of the baffle frame 4 is higher than that of the platform 5 .

[0037] In the above structure, the iron filings are flushed by water so that the iron filings on the platform 5 can be directly flushed into the filter bucket 604, so that the iron filings will not fall under the platform 5. The baffle frame 4 is set to block the water and iron filings so that the water and iron filings can only flow toward the filter bucket 604.

[0038] A metal workpiece processing process comprises the following steps: S1: placing the workpiece on platform 5; S2: The operation of the elevator 2 drives the drilling mechanism 1 to move downward; S3: The drilling motor 103 rotates to process the workpiece, and the power output shaft of the drilling motor 103 drives the left small gear 104 to rotate, and the left small gear 104 drives the left large gear 105 and the right small gear 106 to rotate, and the right small gear 106 rotates to drive the right large gear 107 to rotate, and the rotating column 108, the disk 109 and the column 110 rotate following the right large gear 107, and the rotation of the disk 109 drives the movable rod 111, the sealing cover 116 and the rubber plug 114 to move, and the rubber plug 114 moves toward the disk 109 so that the water in the water tank 601 enters the liquid storage cylinder 115 through the water inlet pipe 118 and the water inlet check valve 117, and the rubber plug 114 moves in the opposite direction of the disk 109, and then the water is squeezed, so that the water enters the water outlet check valve 119, the water outlet pipe 120 and the cooling pipe 121, and then sprayed out through the water supply pipe 122 to cool the workpiece and the drill bit, and the iron filings are processed at the same time.

[0039] Working principle: when in use, by fixing the workpiece on the platform 5, when the punching motor 103 is running to punch the workpiece, the power output shaft of the punching motor 103 drives the left small gear 104 to rotate, and the rotation of the left small gear 104 drives the left large gear 105 to rotate, and the right small gear 106 also rotates, and the right small gear 106 drives the right large gear 107 to rotate when rotating, and the rotation of the right large gear 107 drives the rotating column 108 to rotate, and the rotation of the rotating column 108 drives the disc 109 to rotate. When the disc 109 rotates, it will drive the movable rod 111, the moving rod 113 and the rubber plug 114 to reciprocate. When the rubber plug 114 moves toward the direction of the disc 109, the water inlet check valve 117 is opened and the water outlet check valve 119 is in a closed state. The suction force of the rubber plug 114 moving toward the direction of the disc 109 is used to draw water in the water tank 601 through the water inlet pipe 118 and the water inlet check valve 1 17 is drawn into the liquid storage cylinder 115, so that the liquid storage cylinder 115 is filled with water. When the rubber plug 114 moves in the opposite direction to the disc 109, the thrust generated by the rotation of the disc 109 causes the rubber plug 114 to squeeze the water in the liquid storage cylinder 115. At this time, the water closes the water inlet check valve 117 and opens the water outlet check valve 119, so that the water enters the water outlet pipe 120 and the cooling pipe 121 through the water outlet check valve 119, and then is sprayed to the drill bit and the workpiece through the water supply pipe 122. At this time, the water can flush the iron filings at the punching point onto the filter bucket 604, and the water and iron filings move toward the vertical groove 606. The larger iron filings are blocked by the blocking bar 605, and part of the water and iron filings flow into the filter box 602 through the connecting tube 608. At this time, the water in the filter box 602 will surge, and the iron filings are blocked by the filter element 607, so that there is no iron filings in the water above the filter element 607, and the water enters the water tank 601 through the through groove 603, so that the water can be recycled.
