[0002] In the hardware processing industry, drilling is one of the most basic and common processing procedures.

[0003] Currently, when drilling disc-shaped hardware products, such as flanges, a pressure-holding mechanism is often used to position the product from above. However, in this positioning method, the pressure structure covers part of the top surface of the hardware product, which affects the drilling operation of the drilling equipment on different areas of the top surface of the hardware product.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-6 This utility model provides a technical solution: a hardware processing positioning drilling machine, including a worktable 1, a portal frame 2 fixed to the top surface of the worktable 1, a transverse base 3 that moves laterally along the top of the portal frame 2, a vertical base 4 that moves vertically along the transverse base 3, and a drilling mechanism 5 fixed to the front wall of the vertical base 4. The transverse base 3 is slidably engaged with the top beam of the portal frame 2 via guide rails and sliders, and is driven by a telescopic cylinder or a servo motor matched with gears and racks to achieve lateral movement of the transverse base 3 along the top of the portal frame 2. The vertical base 4 is slidably engaged with the front wall of the transverse base 3 via guide rails and sliders, and is driven by a telescopic cylinder or a servo motor matched with gears and racks to achieve vertical movement of the vertical base 4 along the transverse base 3. The drilling mechanism 5 consists of a drive motor and a drill bit. The lateral movement of the base 3 is used to adjust the lateral position of the drilling mechanism 5, while the vertical movement of the base 4 is used to drive the drilling mechanism 5 to move vertically, thereby enabling the drilling and retraction processes. A drive motor drives the drill bit to rotate at high speed to perform drilling operations on metal products.

[0031] A rectangular groove 1.1 is longitudinally provided in the center of the top surface of the workbench 1. Guide rails 1.2 are fixed on both sides of the rectangular groove 1.1. Slider blocks 7.2 that are slidably engaged with the guide rails 1.2 are fixed on both sides of the bottom surface of the sliding plate 7. The rear end of the piston cylinder of the push-pull telescopic cylinder 6 is connected to the rear wall of the rectangular groove 1.1, and the front end of the piston rod of the push-pull telescopic cylinder 6 is connected to the bottom surface of the sliding plate 7. That is, the push-pull telescopic cylinder 6 is used to push and pull the sliding plate 7 to slide back and forth.

[0032] The sliding plate 7 has multiple radially extending grooves 7.1 evenly distributed around its center. The clamping mechanism 8 includes a square column housing 8.1 whose top is radially slidably engaged with the bottom of the groove 7.1; a block 8.2 slidably fitted into the inner cavity of the square column housing 8.1; a vertical rod 8.3 whose bottom end is fixed to the top surface of the block 8.2 and slidably engaged with the groove 7.1; a spring 8.5 supported between the block 8.2 and the outer end wall of the inner cavity of the square column housing 8.1; and a plate 8.7 hinged to the outer end of the square column housing 8.1. A connecting shaft 8.8 is vertically fitted onto the outer end of the plate 8.7. The square column housing 8.1 has a groove 8.1.1 along its axial direction at the center of its top surface, which is slidably engaged with the vertical rod 8.3. An ear seat 8.6, rotatably connected to the plate 8.7, is fixed to the outer end face of the square column housing 8.1.

[0033] The rotary table 9 includes a fixed inner ring 9.1 fixed to the bottom surface of the sliding plate 7 and located on the periphery of the slide groove 7.1, and an outer gear ring 9.2 rotatably fitted outside the fixed inner ring 9.1. The outer gear ring 9.2 is provided with a plurality of sleeve holes 9.2.1 evenly in the circumferential direction, and the top of the connecting shaft 8.8 is rotatably fitted into the corresponding sleeve hole 9.2.1.

[0034] The drive unit 10 includes a bracket 10.1 fixed to the bottom surface of the sliding plate 7, a servo motor 10.2 fixed to the bottom of the inner cavity of the bracket 10.1, and a gear 10.3 fixedly mounted on the power output shaft of the servo motor 10.2 and meshing with the external gear ring 9.2.

[0035] In summary, when processing disc-shaped hardware products, the hardware products are placed in the middle of the top surface of the sliding plate 7. Then, the servo motor 10.2 drives the outer gear ring 9.2 to rotate through the gear 10.3. The outer gear ring 9.2 pushes the square column housing 8.1 through the connecting shaft 8.8 and the plate 8.7, causing the square column housing 8.1 to slide from the bottom of the slide groove 7.1 towards the middle. At the same time, the vertical rods 8.3 also slide along the slide groove 7.1 towards the middle until multiple vertical rods 8.3 are pressed against the outer peripheral wall of the disc-shaped hardware product to achieve the positioning of the hardware product.

[0036] Then, the sliding plate 7 is pulled back to the corresponding position of the gantry 2 by the push-pull telescopic cylinder 6 to facilitate drilling. During this process, the push-pull telescopic cylinder 6 extends and retracts accordingly to coordinate with the drilling mechanism 5 to adjust the drilling position.

[0037] When the servo motor 10.2 reverses, it drives the external gear ring 9.2 to reverse through the gear 10.3. The external gear ring 9.2 then pulls the square column housing 8.1 through the connecting shaft 8.8 and the plate 8.7, causing the square column housing 8.1 and the vertical rod 8.3 to slide outward along the slide groove 7.1, so as to facilitate the clamping and positioning of the disc-shaped hardware product.

[0038] Among them, the spring 8.5 can provide a cushioning effect, making it easier for multiple vertical bars 8.3 to fit and press better against the outer wall of the hardware product.

[0039] To prevent scratches on the outer wall of the vertical rod 8.3 when clamping and fixing hardware products, a sleeve 8.4 is threaded onto the top of the vertical rod 8.3, and the sleeve 8.4 is covered with a flexible rubber layer.
