Description

Technical Field

[0002] A drilling and milling machine is a combination of drilling, milling, grinding and other functions. It is often used for processing small and medium-sized workpieces. It can complete holes, grooves and other structures on the workpiece at one time. For example, a multi-axis drilling and milling machine has multiple spindles in different directions. At the same time, it can process multiple surfaces of the workpiece with a rotatable fixture. In addition, when processing simple workpieces, such as common regular shapes of plates and blocks, a gantry drilling and milling machine can be used for processing. The blank is directly placed or fixed on the workbench, and processing can be achieved on one side of the blank. When processing large blanks, this type of machine can ensure processing accuracy and production economy. When the existing CNC drilling and milling machine is processing the workpiece, the corresponding fixture is used to complete the clamping and transportation of the workpiece to be processed. The CNC host can control the drilling and milling head for precise control, and the workpiece is manually unloaded and transported after the processing is completed. For workpieces with larger volume and heavier weight, a hoist is required to lift and transport the material.

[0024] 1. When the present invention is in use, the workpiece is placed on the workbench, the lifting frame is started to move the material picking mechanism above the workpiece, and the adjustable structure of the material picking mechanism is used to pick up and fix workpieces of different sizes, then the lifting frame is reset to make the workpiece leave the workbench, and the driving mechanism drives the truss to move on the guide rail to transport the workpiece. After the workpiece moves to the electromagnetic suction cup or the grid plate, the lifting frame moves down to make the workpiece fall above the electromagnetic suction cup and the grid plate, and the workpiece is fixed by the magnetic suction force generated by the electromagnetic suction cup, or when it is on the grid plate, it is pressed by the material picking mechanism, so that the workpiece can be fixed, which is convenient for the drilling and milling host to perform drilling and milling operations.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] Embodiment 1: refer to the attached Figure 1-9The integrated drilling and milling processing machine tool comprises a drilling and milling host 5, an X-axis driving mechanism 2, a Y-axis driving mechanism 3, a Z-axis driving mechanism 4, a control host and a base plate 14. The Y-axis driving mechanism 3 is fixed on the X-axis driving mechanism 2 through a connecting seat, and the Z-axis driving mechanism 4 is installed on the Y-axis driving mechanism 3 through a mounting seat. The drilling and milling host 5 is installed on the Z-axis driving mechanism 4. The upper end of the base plate 14 is fixedly connected with a frame 1, and the X-axis moving mechanism is symmetrically installed on both sides of the frame 1. A lifting frame is installed in the frame 1, and the lifting frame consists of two laterally arranged guide rails 10. A truss 12 is installed between the two guide rails 10. A material picking mechanism is installed on the upper end of the truss 12. The adjustable structure of the material picking mechanism is used to pick up, place and fix workpieces of different sizes. Driving mechanisms are installed at both ends of the truss 12. The driving mechanism is used to drive the truss 12 to move on the guide rail 10 to transport the workpiece. A protective cover 15 is installed on the upper end of the truss 12, and the material picking mechanism is installed below the protective cover 15.

[0039] A workbench 6 is installed at the upper end of the base plate 14, and an electromagnetic suction cup 39 and a grille plate 7 are fixedly connected to the upper end of the workbench 6. The upper ends of the electromagnetic suction cup 39 and the grille plate 7 are located in the same horizontal plane. An opening is provided at one end of the frame 1, and two door panels are hinged at the opening through a hinge, and the two door panels are connected by a lock.

[0040] When the present invention is in use, the workpiece is placed on the workbench 6, the lifting frame is started to move the material picking mechanism to the top of the workpiece, and the adjustable structure of the material picking mechanism is used to pick up and fix workpieces of different sizes. Then the lifting frame is reset to make the workpiece leave the workbench 6, and the truss 12 is driven by the driving mechanism to move on the guide rail 10 to transport the workpiece. After the workpiece moves to the electromagnetic suction cup 39 or the grid plate 7, the lifting frame moves down to make the workpiece fall on the electromagnetic suction cup 39 and the grid plate 7, and the workpiece is fixed by the magnetic attraction force generated by the electromagnetic suction cup 39, or when it is on the grid plate 7, it is pressed by the material picking mechanism. In this way, the workpiece can be fixed, which is convenient for the drilling and milling main machine 5 to perform drilling and milling operations.

[0041] After drilling and milling are completed, the above picking and placing actions are repeated through the material picking mechanism to move the workpiece and scraps to the opening close to the frame 1, which is convenient for technicians to operate and pick up the workpiece. At the same time, the material picking mechanism can also clean the drilling and milling debris from above the workbench 6 to one side of the bottom plate 14 for subsequent unified cleaning.

[0042] Embodiment 2: Based on embodiment 1, the difference is that;

[0043] See attached Figure 3-8The material-taking mechanism includes a transverse axis 32, both ends of which are fixedly connected with screw rods 29, the spiral directions of the two screw rods 29 are opposite, and the walls of the screw rods 29 are threadedly connected with threaded sleeves 31, and both ends of the threaded sleeves 31 are rotatably connected with pull rods 20 through pin shafts, and the ends of the two pull rods 20 away from the threaded sleeves 31 are rotatably connected with support arms 13 through shaft pins, one end of the support arm 13 is rotatably connected to one side of the truss 12 through a rotating shaft, and the other end of the support arm 13 is fixedly connected to a first electromagnet 18, the transverse axis 32 and the two screw rods 29 are rotatably connected to the upper end of the truss 12 through a bearing seat, and the upper end of the truss 12 is fixedly connected to a first motor 19, and the output end of the first motor 19 is fixedly connected to one end of one of the screw rods 29.

[0044] A plurality of strip holes are provided at the upper end of the protective cover 15, and side plates 16 are provided at the plurality of strip holes. A fixing portion 35 is provided on one side of the plurality of side plates 16. The side wall of the threaded sleeve 31 is symmetrically fixedly connected to two connecting plates 30, and the fixing portion 35 passes through the strip through hole and is fixedly connected to one end of one of the connecting plates 30. Two top plates 34 are provided at the upper end of the protective cover 15, and the two top plates 34 are fixed to one end of the side plates 16, and a first electric push rod 33 is fixedly connected to one end of the top plate 34, and a support is fixedly connected to the output end of the first electric push rod 33, and a V-shaped clamping plate 17 is fixedly connected to one end of the support, and an anti-slip strip is fixedly connected to one side of the support arm 13, and an anti-slip strip is provided on one side. An arc plate 21 is fixedly connected to the corner of one end of the support arm 13;

[0045] Bending parts are symmetrically arranged on both sides of the truss 12, and two main shafts are rotatably connected between the two bending parts through ball bearings. Support rollers 36 are fixedly connected to the shaft walls of the two main shafts, and a conveyor belt 37 is wound around the support rollers 36. A second electromagnet 38 is arranged in the conveyor belt 37. The second electromagnet 38 is fixed between the bending parts. A second motor 22 is fixedly connected to one side of one of the bending parts, and the output end of the second motor 22 passes through a rolling bearing and is fixedly connected to one end of one of the main shafts.

[0046] The present invention is provided with a material taking mechanism, which uses the first motor 19 as a driving screw rod 29 and a horizontal shaft 32 to make the two threaded sleeves 31 move relatively, and when the threaded sleeve 31 moves, it drives the pull rod 20 to make the support arm 13 swing, and after the support arm 13 swings, it drives the first electromagnet 18 to move. After the first electromagnet 18 swings, the distance between the multiple electromagnets increases, so that the workpiece can be sucked by the magnetic attraction of the first electromagnet 18, and at the same time, the second electromagnet 38 arranged under the truss 12 can generate suction force on the workpiece after being energized to generate magnetic attraction force, so that the stability when picking and placing the workpiece can be improved. In addition, the first electromagnet 18 can be replaced by a negative pressure suction cup, which can also generate suction force on the flat workpiece;

[0047] like Figure 6As shown, the symmetrically arranged support arms 13 can clamp workpieces with special structures through the anti-slip strip fixed on one side thereof, and the arc-shaped plate 21 can clamp smaller workpieces when the support arms 13 swing, and one side of the workpiece contacts the bent portion of the truss 12 during the clamping process, so that the workpiece can be stably clamped;

[0048] like Figure 7 and Figure 8 As shown, when the threaded sleeve 31 moves, it drives the fixing part 35 to move the side plate 16, and when the side plate 16 moves, it drives the first electric push rod 33 and the top plate 34 to move, and when the top plate 34 moves, it drives the V-shaped clamping plate 17 to move, so that the workpiece can be clamped above the truss 12, and the first electric push rod 33 arranged on the top plate 34 can directly push the V-shaped clamping plate 17 to move, so that the secondary force clamping of the workpiece can be achieved;

[0049] like Fig. 9 As shown, a conveyor belt 37 is installed around the second electromagnet 38, and the conveyor belt 37 is supported by the support roller 36. When the second motor 22 drives the support roller 36 to rotate, the conveyor belt 37 rotates synchronously. In this way, the magnetic attraction generated by the second electromagnet 38 can penetrate the conveyor belt 37 to absorb the metal debris scattered above the workbench 6. Since the conveyor belt 37 is rotating, the conveyor belt 37 can maintain friction with the metal debris under the action of the magnetic force, so that the metal debris moves to one side with the conveyor belt 37. When it moves to the vicinity of the support roller 36, the magnetic force gradually weakens, and the metal debris falls under the action of inertia. In this way, the metal debris above the workbench 6 can be cleaned up, which is convenient for technical personnel to use.

[0050] In addition, when the truss 12 moves downward, the lower ends of the first electromagnet 18 and the second electromagnet 38 are at the same horizontal plane, so that the workpiece can be pressed and fixed, especially a larger plate-shaped workpiece, thereby realizing the versatility of the material removal mechanism.

[0051] Embodiment 3: Based on embodiment 1, the difference is that;

[0052] See attached Figure 2-3 The driving mechanism includes a rack 25, which is fixed to the upper end of the guide rail 10. The upper end of the truss 12 is fixedly connected to a reduction motor 23, and the output end of the reduction motor 23 is fixedly connected to a gear 24, which meshes with the rack 25. One end of the truss 12 extends into the guide rail 10 and is fixedly connected to two track wheels 27. Both track wheels 27 are in contact with the inner wall of the lower end of the guide rail 10. A positioning wheel 26 is arranged in the track, and the positioning wheel 26 is fixed to the upper end of the scale. The guide rail 10 is a C-shaped structure, and an inner folding edge is arranged at the edge of the guide rail 10. The side wall of the truss 12 is rotatably connected to a plurality of limiting wheels 28 through a support shaft, wherein two limiting wheels 28 are in contact with one inner wall of the guide rail 10, and the other two limiting wheels 28 are in contact with one side of the inner folding edge;

[0053] The lifting frame also includes four guide columns 8, which are symmetrically fixed at the four corners of the base plate 14. A fixing plate 9 is fixedly connected to the inner edge of the frame 1, and the fixing plate 9 is fixedly connected to the upper ends of the guide columns 8. The side walls of the guide rails 10 are sleeved with the side walls of the guide columns 8 through guide holes. Two second electric push rods 11 are fixedly connected to the upper end of the base plate 14, and the output ends of the two second electric push rods 11 are respectively fixed at the lower end centers of the two guide rails 10.

[0054] The present invention is provided with a driving mechanism, which utilizes two second electric push rods 11 to simultaneously push the two guide rails 10 to move, and the two guide rails 10 simultaneously push the truss 12 to move. When the truss 12 moves, the material picking mechanism installed above it can realize reciprocating motion for picking up and placing workpieces. When the reduction motor 23 is working, the driving gear 24 rolls on the rack 25, so that the truss 12 can be driven by the reduction motor 23 to move horizontally, so that the workpiece on the material picking mechanism can be moved, and after the material picking mechanism completes its work, the reduction motor 23 can drive the truss 12 to move to a position away from the drilling and milling main machine 5 without affecting the normal drilling and milling operation.
