Description

Technical Field

[0001] This utility model relates to the field of drilling mechanism technology, specifically a square hole drilling mechanism that facilitates material discharge. Background Technology

[0002] A square hole drilling machine is a mechanical device that can process square holes. Its core principle is based on the special geometry of the Reuleaux triangle. The Reuleaux triangle is a convex planar shape with a constant width. Its characteristic is that its width remains unchanged no matter how the curve rotates. This property allows the Reuleaux triangle-shaped drill bit to drill a square with rounded corners.

[0003] For example, Chinese utility model patent application number 202222147540.5 discloses a square hole drilling mechanism for easy material discharge, including a worktable, a support, a top plate, a drive mechanism, a drill rod, a drill sleeve, and a collection bin. The support is vertically fixed to the worktable, and the top plate is horizontally fixed to the top of the support. The drive mechanism is fixed to the lower surface of the top plate, and the drill rod is vertically arranged with its upper end connected to the drive mechanism. The drill sleeve is fitted around the drill rod, and its upper end is fixed to the drive mechanism. The drill sleeve is a square tube with an opening on its side wall, and a cover is sealed to the opening. The cover is connected to the inlet of the collection bin, and the outlet of the collection bin is connected to a suction machine. A filter plate is installed in the inner cavity of the collection bin, located between the inlet and outlet. This square hole drilling mechanism provides a closed-loop treatment for the debris generated during drilling, effectively avoiding problems such as poor debris discharge, debris accumulation around the processing table, and debris easily splashing into the worker's eyes.

[0004] However, the aforementioned square hole drilling mechanism is not easily adaptable to irregularly shaped workpieces of different sizes and shapes during use. The adjustment and drilling process is cumbersome, and it is also difficult to quickly release the clamps and remove the workpiece after drilling, affecting the material discharge and cleaning effect. Therefore, those skilled in the art have provided a square hole drilling mechanism that facilitates material discharge to solve the problems mentioned in the background art. Utility Model Content

[0033] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0034] According to one embodiment of the present invention, in conjunction with Figures 1-4 As shown. A square hole drilling mechanism for easy material discharge includes a fixed base 1, a metal frame 2 fixed to the top of the fixed base 1, a square hole drilling device body 3 fixed to the top of the metal frame 2, a worktable 4 installed on the top of the fixed base 1, and a positioning mechanism 5 provided on the top of the worktable 4;

[0035] The positioning mechanism 5 includes a servo motor 51, a ball screw 52 fixed to the outside of the output shaft of the servo motor 51, a self-locking ball nut 53 threaded to the outside of the ball screw 52, ​​a movable guide sleeve 54 fixed to the outside of the self-locking ball nut 53, a support frame 55 mounted on the top of the worktable 4, a guide sliding sleeve 56 provided on one side of the movable guide sleeve 54, a guide rail 57 fixed on the top of the worktable 4, a fixing pad 58 fixed to the outside of the servo motor 51, a clamping mechanism 6 provided to the outside of the movable guide sleeve 54, the fixing pad 58 and the worktable 4 fixedly connected, the servo motor 51 and the worktable 4 fixedly connected, a through hole opened inside the movable guide sleeve 54, the size of the through hole being adapted to the size of the ball screw 52, ​​the guide sliding sleeve 56 movably sleeved on the outside of the guide rail 57, the guide rail 57 fixedly connected to the worktable 4 by bolts, the self-locking ball nut 53 and the movable guide sleeve 54 being bonded and fixed together, and one end of the ball screw 52 being connected to the support frame 55.

[0036] The clamping mechanism 6 includes a clamping pad 61, with a movable groove 62 inside the clamping pad 61. A movable block 63 is slidably connected inside the movable groove 62. A limit block 64 is fixed to one end of the movable block 63, and an auxiliary positioning plate 65 is fixed to one end of the movable block 63. A movable threaded post 66 is fixed to the top of the movable block 63, and a limit pad 67 is installed on the top of the movable threaded post 66. A washer 68 is movably sleeved on the outside of the movable threaded post 66, and a positioning nut 69 is threadedly connected to the outside of the movable threaded post 66. The size of the movable groove 62 is adapted to the size of the movable block 63, and a limit groove for accommodating the movement of the movable threaded post 66 is provided inside the clamping pad 61.

[0037] In this embodiment, when drilling square holes in a workpiece, the workpiece is first placed on the worktable 4. Then, two servo motors 51 are started, causing the output shafts of the servo motors 51 to drive the ball screw 52 to rotate. This causes the self-locking ball nut 53 to move the guide sleeve 54 and the clamping pad 61 horizontally. At this time, the guide sliding sleeve 56 slides on the outside of the guide rail 57, providing support. After the corresponding surface of the clamping pad 61 is in close contact with the outside of the workpiece, the main body 3 of the square hole drilling device can be started to drill square holes. This allows for quick adaptation to irregularly shaped workpieces of different sizes and shapes, ensuring that the workpiece does not shift during processing. After drilling, the limit can be quickly released and the workpiece can be removed. The debris generated during the square hole drilling process is also easy to discharge and clean, achieving convenient material discharge. Objective: By providing a clamping mechanism 6, the position of the auxiliary positioning plate 65 can be adjusted when clamping the workpiece. During adjustment, the limiting pad 67 is moved, causing the movable threaded column 66 and the movable block 63 to move. At this time, the movable block 63 moves the limiting block 64 and the auxiliary positioning plate 65 simultaneously. After the auxiliary positioning plate 65 moves to the appropriate position, the positioning nut 69 on the outside of the movable threaded column 66 is rotated, so that the corresponding surface of the positioning nut 69 is in close contact with the washer 68, and the bottom surface of the washer 68 is in close contact with the clamping pad 61. This facilitates the adjustment and fixation of the position of the auxiliary positioning plate 65, enabling the auxiliary positioning plate 65 to play an auxiliary positioning role. This solves the problems of unstable clamping and low efficiency in traditional square hole drilling equipment, and is beneficial to the square hole drilling process.

[0038] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
