[0014] Beneficial effects of the present invention:

[0015] 1. The intelligent multi-hole double-part continuous processing automatic drilling machine of the present invention has fixtures for clamping workpieces installed on both sides of the support, and gear boxes with multiple drill bits installed on both sides of the support. After the driving motor circuit is turned on, the driving motor drives the gears in the gear box to rotate through the transmission belt, so that the drill bits installed on multiple output ends of the gear box rotate together.

[0016] 2. In the intelligent porous double-part continuous processing automatic drilling machine of the present invention, when the support member is close to a gear box, the support member squeezes the extrusion part, and the extrusion part drives the baffle plate to move after being squeezed. At this time, the dovetail tenon strip slides in the dovetail tenon groove relative to the baffle plate, thereby limiting the movement trajectory of the baffle plate. During the movement of the baffle plate, the movable rod drives the pressure plate to move in the circular tube, so that the pressure plate and the blocking cover work together to squeeze the spring, and the spring undergoes elastic deformation. When the support member is close to another gear box, under the action of the spring rebound force, the baffle plate slides in the opposite direction, thereby resetting the baffle plate. At this time, the baffle plate is in a state of shielding the rotating drill bit. When a person removes the workpiece on the support member, the baffle plate can prevent the person's hands from accidentally touching the rotating drill bit, thereby improving safety.

[0028] A support 2 for installing a workpiece fixture is provided between the two hollow boxes 4. The lower end of the support 2 is in sliding contact with the base 1. A threaded hole 24 arranged along the length direction of the base 1 is opened at the lower position of one side of the support 2. A threaded rod 3 is connected to the inner thread of the threaded hole 24. The threaded rod 3 is rotatably installed between the two hollow boxes 4. One end of the threaded rod 3 is fixedly connected to the output end of a servo motor 27. The servo motor 27 is installed in the hollow box 4. The servo motor 27 is controlled by PLC to realize intelligent automatic control of the movement of the support 2. Fixtures for clamping the workpiece are installed on both sides of the support 2, and multiple drill bits are installed on both sides of the support 2. After the gear box 28 of the head 10 is connected to the circuit of the drive motor 12, the drive motor 12 drives the gears in the gear box 28 to rotate through the transmission belt 14, so that the drill bits 10 installed on multiple output ends of the gear box 28 rotate together. When the servo motor 27 is controlled to rotate forward or reverse, the servo motor 27 drives the support member 2 to slide on the base 1 through the threaded rod 3, so that the workpiece installed on the support member 2 is close to the drill bit 10, which is convenient for drilling multiple holes in the workpiece at a time. During the forward or reverse rotation of the servo motor 27, there is always a workpiece in a processing state, and at the same time, the other processed workpiece is taken out, thereby realizing continuous processing of two parts and improving work efficiency.

[0029] A shielding plate 5 for shielding the drill bit 10 is installed on one side of the two gear boxes 28, and a dovetail tenon bar 6 is fixedly connected to the side of the gear box 28 facing the shielding plate 5. The dovetail tenon bar 6 is fixed to one side of the gear box 28 and arranged along the length direction of the base 1. The dovetail tenon bar 6 is inserted in the dovetail tenon groove 20. The dovetail tenon groove 20 is opened on the side of the shielding plate 5 facing the gear box 28. The dovetail tenon bar 6 is inserted in the dovetail tenon groove 20 to realize the connection between the shielding plate 5 and the gear box 28.

[0030] A movable rod 7 arranged along the length direction of the base 1 is fixedly connected to the side of the baffle plate 5 facing away from the gear box 28, and the end of the movable rod 7 away from the baffle plate 5 extends into the round tube 8, and the round tube 8 is fixedly connected to the gear box 28.

The side of the baffle plate 5 facing the gear box 28 is fixedly connected to an extrusion portion 19 in contact with the support member 2, and the extrusion portion 19 and the baffle plate 5 are an integrally formed structure, and the extrusion portion 19 and the baffle plate 5 are arranged at an angle of 90°. When the support member 2 is close to a gear box 28, the support member 2 squeezes the extrusion portion 19. After being squeezed, the extrusion portion 19 drives the baffle plate 5 to move. At this time, the dovetail tenon bar 6 slides in the dovetail tenon groove 20 relative to the baffle plate 5, which plays a role in limiting the moving trajectory of the baffle plate 5. During the movement of the baffle plate 5, the movable rod 7 drives the pressure plate 26 to move in the circular tube 8, so that the pressure plate 26 and the blocking cover 9 work together to squeeze the spring 25, and the spring 25 undergoes elastic deformation. When the support 2 is close to another gear box 28, under the action of the rebound force of the spring 25, the baffle plate 5 slides in the opposite direction, thereby resetting the baffle plate 5. At this time, the baffle plate 5 is in a state of shielding the rotating drill bit 10. When a person removes a workpiece on the support 2, the baffle plate 5 blocks the person's hand from accidentally touching the rotating drill bit 10, thereby improving safety.

[0031] As an embodiment of the present invention: a soft rubber strip 11 is provided at one end of the shielding plate 5 away from the movable rod 7, and the soft rubber strip 11 is fixedly connected to the shielding plate 5 by glue. The two corners of the soft rubber strip 11 away from the shielding plate 5 are processed with rounded corners 23, and a plurality of protrusions 22 are fixedly connected to the side of the soft rubber strip 11 facing the shielding plate 5, and the protrusions 22 are fixedly connected to the soft rubber strip 11. A plurality of fixing holes 21 matching with the protrusions 22 are opened on the side of the shielding plate 5 facing the soft rubber strip 11, and the protrusions 22 are fixed in the fixing holes 21. The plurality of protrusions 22 on the soft rubber strip 11 are respectively fixed in the plurality of fixing holes 21 on the shielding plate 5, thereby increasing the contact range between the soft rubber strip 11 and the shielding plate 5, and improving the stability of the connection between the soft rubber strip 11 and the shielding plate 5. By installing a soft rubber pad at one end of the shielding plate 5 close to the support member 2, hard collision between the hands of personnel and the shielding plate 5 when taking and placing workpieces can be avoided, thereby improving safety.

[0032] As an embodiment of the present invention: two supports 16 are symmetrically fixedly connected at the lower position of the outer surface of the driving motor 12, and two vertically arranged through holes are symmetrically opened on the upper surface of the support 16. Studs 18 are inserted in the through holes, and the lower ends of the studs 18 are fixedly connected to the gear box 28. Nuts 17 threadedly connected to the studs 18 are provided on the upper and lower sides of the through holes. The studs 18 are inserted in the through holes of the supports 16, and the lower ends of the studs 18 are fixedly connected to the gear box 28. Subsequently, the studs 18 and the supports 16 are fixedly connected by two nuts 17 to fix the position of the driving motor 12. By adjusting the relative positions of the supports 16 and the studs 18, the spacing between the driving motor 12 and the gear box 28 can be adjusted, and the tension of the transmission belt 14 can be adjusted.

[0034] Specific implementation method: fixtures for clamping the workpiece are installed on both sides of the support member 2, and gear boxes 28 with multiple drill bits 10 installed are set on both sides of the support member 2. After the circuit of the driving motor 12 is turned on, the driving motor 12 drives the gears in the gear box 28 to rotate through the transmission belt 14, so that the drill bits 10 installed on multiple output ends of the gear box 28 rotate together. When the servo motor 27 is controlled to rotate forward or reverse, the servo motor 27 drives the support member 2 to slide on the base 1 through the threaded rod 3, so that the workpiece installed on the support member 2 is close to the drill bit 10, which is convenient for drilling multiple holes in the workpiece at a time. During the forward or reverse rotation of the servo motor 27, there is always a workpiece in a processing state, and at the same time, the other processed workpiece is taken out, so as to realize the continuous processing of two parts and improve work efficiency.

[0035] When the support member 2 is close to a gear box 28, the support member 2 squeezes the extrusion part 19, and the extrusion part 19 drives the baffle plate 5 to move after being squeezed. At this time, the dovetail tenon strip 6 slides in the dovetail tenon groove 20 relative to the baffle plate 5, which plays a role in limiting the movement trajectory of the baffle plate 5. During the movement of the baffle plate 5, the movable rod 7 drives the pressure plate 26 to move in the circular tube 8, so that the pressure plate 26 and the blocking cover 9 work together to squeeze the spring 25, and the spring 25 undergoes elastic deformation. When the support member 2 is close to another gear box 28, under the action of the rebound force of the spring 25, the baffle plate 5 slides in the opposite direction, thereby resetting the baffle plate 5. At this time, the baffle plate 5 is in a state of shielding the rotating drill bit 10. When a person removes a workpiece from the support member 2, the baffle plate 5 blocks the person's hand from accidentally touching the rotating drill bit 10, thereby improving safety.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.
