Detailed Implementation

[0019] like Figure 1 , 2 As shown, a slanted hole expander for plywood includes a main support 1, an adjusting frame 2, and a positioning auxiliary structure 3. The positioning auxiliary structure 3 is bolted to the main support 1. The main support 1 has an inverted "L" shape. The adjusting frame 2 is snapped onto one end of the main support 1. The adjusting frame 2 is movably connected to the adjusting groove 5 on the side of the main support 1 via an adjusting screw 4. The positioning auxiliary structure 3 consists of a support base 6, a flipping bracket 7, and a limiting rod 8. The support base 6 is mounted on the main support 1. The end is connected to the flipping bracket 7 via a rotating shaft. The flipping bracket 7 is equipped with a limit rod 8 via the rotating shaft. The limit rod 8 passes through the U-shaped groove 9 and is connected to the limit block 10. The U-shaped groove 9 and the support base 6 are an integral structure. The surface of the main bracket 1 is provided with several scales 11. The adjustment frame 2 is provided with drill holes 12. The drill holes 12 and the oblique holes 13 on the surface of the adjustment frame 2 are connected. The back of the adjustment frame 2 is provided with chip removal holes 14. The extended end of the main bracket 1 and the inner wall of the main bracket 1 form a receiving platform 15. The limit block 10 is made of rubber.

[0020] In actual operation, the main support 1 has an inverted "L" shaped structure, which gives it good stability. The end is used to snap on the adjustment frame 2, which is convenient for installation and disassembly. The surface of the main support 1 has several scales 11. When using it, the scales 11 can be adjusted according to the actual thickness of the plywood. The extended end of the main support 1 and the inner wall of the main support 1 form a receiving platform 15. During the drilling process, the sawdust and other waste materials can fall directly onto the receiving platform 15, which is convenient for centralized cleaning and keeps the working environment clean.

[0021] The adjusting frame 2 is movably connected to the adjusting groove 5 on the side of the main support 1 via the adjusting screw 4, so as to realize the flexible adjustment of the angle. The adjusting frame 2 is provided with a drilling hole 12, which is connected to the inclined hole 13 on the surface of the adjusting frame 2. This design allows the drill bit to pass smoothly through the adjusting frame 2 for inclined drilling during the drilling process. The back of the adjusting frame 2 is provided with a chip removal hole 14. During the drilling process, waste materials such as wood chips can be discharged through the chip removal hole 14 to avoid accumulation inside the adjusting frame 2 and affecting the drilling effect.

[0022] The positioning auxiliary structure 3 is bolted to the main support 1 and consists of a support base 6, a flipping bracket 7, and a limiting rod 8. The support base 6, mounted on the main support 1, provides support for the entire positioning auxiliary structure 3. The end of the support base 6 is connected to the flipping bracket 7 via a pivot, allowing the flipping bracket 7 to rotate around the pivot to adapt to different working conditions. The flipping bracket 7 is fitted with the limiting rod 8 via the pivot. The limiting rod 8 passes through a U-shaped groove 9 and connects to a limiting block 10. The U-shaped groove 9 and the support base 6 are an integral structure. The cooperation of the limiting rod 8 and the limiting block 10 positions the plywood to be drilled, preventing displacement during drilling and ensuring drilling accuracy.

[0023] The limiting block 10 is made of rubber, which has good flexibility and friction. When positioning the plywood, the rubber limiting block can better fit the surface of the plywood, without damaging the surface, and provides sufficient friction to ensure the stability of the plywood during the drilling process.

[0024] First, install the support base 6 onto the main bracket 1 with bolts to ensure a secure installation. Then, install the flip bracket 7 onto the end of the support base 6 via a rotating shaft. After the rotating shaft is installed, ensure that the flip bracket 7 can rotate flexibly without any jamming.

[0025] Next, the limiting rod 8 is installed on the flip bracket 7, so that it passes through the U-shaped groove 9 on the support base 6, and the limiting block 10 is installed at the end of the limiting rod 8 to ensure that the limiting block 10 is tightly connected to the limiting rod 8.

[0026] Connect the adjustment bracket 2 to the adjustment groove 5 on the side of the main support 1 via the adjustment screw 4. Do not tighten the nut of the adjustment screw 4 too much so that the angle can be adjusted flexibly later.

[0027] When using it, adjust the angle of the adjusting bracket 2 by adjusting the adjusting screw 4 according to the required drilling angle. Observe the scale 11 on the main support 1. After adjusting the angle to the appropriate position, tighten the nut of the adjusting screw 4.

[0028] Place the plywood that needs to be drilled on the workbench, and position the plywood using the limiting block 10 of the positioning auxiliary structure 3 to ensure that the plywood is fixed in position.

[0029] Select a suitable drill bit, install it on the drilling equipment, align the drill bit with the hole 12 on the adjusting frame 2, and start the drilling equipment to perform angled drilling. During the drilling process, pay attention to the drilling situation to ensure smooth drilling.

[0030] After drilling is completed, turn off the drilling equipment and clean up the sawdust and other waste materials on the receiving platform.

[0031] Implementation Results: Following the above implementation steps, the angled hole expander was successfully used for angled drilling on plywood. Through the accurate positioning of the positioning auxiliary structure 3 and the precise adjustment of the angle of the adjusting frame 2, the drilling angle deviation was controlled within ±1°, meeting the requirements for high-precision drilling. The entire drilling process was convenient and quick, increasing work efficiency by approximately 30% compared to traditional angled drilling methods. Simultaneously, the design of the receiving platform and chip removal hole effectively collected and discharged sawdust, keeping the working environment clean and preventing sawdust accumulation from affecting drilling operations.
