Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy technology, and in particular to a drilling and tapping device for aluminum alloy processing. Background Technology

[0002] Aluminum alloys are alloys based on aluminum with the addition of certain amounts of other alloying elements; they are a type of lightweight metal material. In addition to the general properties of aluminum, aluminum alloys also possess specific alloying characteristics due to variations in the types and amounts of alloying elements added.

[0003] After production, aluminum alloys are made into workpieces of different shapes. In order to meet the needs of use, holes are drilled in the workpieces to facilitate subsequent assembly and use. Current drilling equipment uses stamping or drilling methods. Stamping is more effective for thin plates, while drilling is used for thick plates. However, when drilling pipes, the unstable fixing of the pipes can cause deviations in the drilling position, resulting in losses. Utility Model Content

The fixing motor 16 drives the bidirectional screw 8 to rotate, and after the bidirectional screw 8 rotates, it drives the fixing rod 9 to move closer to each other. The fixing rod 9 enters the limiting groove 5 from the fixing groove 30 to clamp the workpiece.

[0028] The output shaft of the fixed motor 16 is connected to one end of the bidirectional screw 8, and the outer wall of the fixed rod 9 is slidably connected to the inner wall of the fixed groove 30. The outer wall of the combination groove 10 is provided with a positioning groove 11, and the outer wall of the combination groove 10 is slidably connected to the combination rod 12. The outer wall of the combination rod 12 is welded with a positioning protrusion. The combination groove 10 on the outer wall of the fixed rod 9 is connected to the fixed rod 9 by the connecting screw 13 and the positioning groove 11, thereby extending the clamping surface and clamping distance of the fixed rod 9. The connecting screw 13 at the top of the fixed rod 9 is installed with a top plate 14 to limit the top of the workpiece, further assisting in fixing the workpiece and improving the stability of the workpiece fixing.

[0029] A connecting screw 13 is welded to one side of the outer wall of the combination rod 12 and the top outer wall of the fixed rod 9. A top plate 14 is inserted into the outer wall of the connecting screw 13 at the top of the fixed rod 9. A nut is threaded onto the outer wall of the connecting screw 13. A contact pad 15 is adhered to one side of the combination rod 12, the top plate 14 and the outer wall of the fixed rod 9.

[0030] The fixed motor 16, the lifting motor 20, the drilling motor 29, and the hydraulic push rod 21 are connected to the switch via wires, and the switch is connected to the power supply via wires.

[0031] Example 2:

[0032] Reference Figure 4-5 The lifting structure 3 includes lifting grooves 17 opened at both ends of the outer wall of one side of the side plate 2, lifting screws 18 rotatably connected in the lifting grooves 17, lifting frame 19 screwed to the outer wall of the lifting screws 18, hydraulic push rods 21 installed at both ends of the outer wall of one end of the lifting frame 19, and mounting brackets 22 installed on the outer wall of the other end of the hydraulic push rods 21. When the lifting frame 19 adjusts the position of the mounting brackets 22, the sliding rods 24 are slidably connected in the lifting frame 19 to ensure the stability of the adjustment process. The sliding rods 24 are slidably connected in the sliding grooves 23 to facilitate movement with lifting and lowering, making it convenient to use.

[0033] Both ends of the lifting frame 19 are slidably connected to the inner wall of the lifting groove 17, and a lifting motor 20 is installed on the top outer wall of the side plate 2. The output shaft of the lifting motor 20 is connected to the top of the lifting screw 18. The lifting motor 20 drives the lifting frame 19 to descend on the side plate 2 through the lifting screw 18. The hydraulic push rod 21 is started to drive the mounting frame 22 to adjust its position in the lifting frame 19 so that the drill rod is located in the processing area. Then the drilling motor 29 is started to drill the workpiece.

[0034] A sliding rod 24 is installed on one side of the outer wall of the mounting bracket 22, and the outer wall of the sliding rod 24 is slidably connected to the lifting frame 19. A sliding groove 23 is opened on the outer wall of the side plate 2 at the sliding rod 24. When the drill rod is positioned, after the drill rod contacts the workpiece, the drilling motor 29 compresses the spring 27 through the fixing ring 28, causing the drilling motor 29 to contract, reducing the damage to the contact surface between the drill rod and the workpiece, and facilitating positioning.

[0036] Working principle: During use, the workpiece is placed in the center groove 6 or limit groove 5 on the base plate 1 according to the shape of the aluminum alloy. The fixed motor 16 at the corresponding position is started to drive the bidirectional screw 8 to rotate. After the bidirectional screw 8 rotates, it drives the fixed rods 9 to move closer to each other. The fixed rods 9 enter the limit groove 5 from the fixed groove 30 to clamp the workpiece. The combination groove 10 on the outer wall of the fixed rod 9 is connected to the combination rod 12 on the fixed rod 9 through the connecting screw 13 and the positioning groove 11, which extends the clamping surface and clamping distance of the fixed rod 9. The connecting screw 13 at the top of the fixed rod 9 is installed with the top plate 14 to limit the top of the workpiece, further assisting in the fixation of the workpiece and improving the stability of the workpiece fixation. The drill rod is installed in the shaft of the drilling motor 29. The lifting motor 20 and the hydraulic push rod 21 are started. The lifting motor 20 drives the lifting frame 19 to descend on the side plate 2 through the lifting screw 18. The hydraulic push rod 21 is started to drive the mounting frame 22 to adjust its position in the lifting frame 19 so that the drill rod is located in the processing area. Then the drilling motor 29 is started to drill the workpiece.
