Description

Technical Field

[0001] This utility model relates to the field of mechanical processing equipment technology, and more specifically, to a CNC radial drilling machine with multi-angle guide rail adjustment. Background Technology

[0002] Traditional radial drilling machines typically operate only on a fixed plane, making it difficult to achieve ideal machining results for workpieces with complex shapes or specific angle requirements. Chinese patent CN212526115U discloses a CNC radial drilling machine that allows for drilling without significant adjustments to the workpiece's position. Even when the drilling location of the workpiece cannot be placed on the worktable, drilling can be performed by changing the angle of the swing arm, thus improving the flexibility of the CNC radial drilling machine. However, in this patent, the swing arm can only change its planar angle, limiting machining accuracy. Utility Model Content

The first worm gear remains stationary, and the rotating first worm gear rotates around the first worm gear, causing the guide ring to rotate around the annular guide rail.

[0008] Preferably, the upper surface of the movable arm is provided with a toothed track, the movable arm serves as a guide for the movable frame, and when the movable arm rotates, it drives the movable frame to rotate synchronously. The movable frame is provided with a drive gear, which meshes with the toothed track.

[0011] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0012] This utility model discloses a CNC radial drilling machine with multi-angle guide rail adjustment. The combination of the first and second guide rail adjustment components enables the machining component to achieve precise angle adjustment in multiple directions, ensuring accurate drilling of complex workpieces. Through the engagement of the threaded rod and the lifting plate, precise control of the drill bit's machining height is achieved, adapting to the needs of workpieces of different thicknesses and improving machining accuracy. The multi-angle adjustment function of the movable arm and machining component allows it to handle workpieces of various shapes and sizes, especially those with complex geometric structures or special angle requirements, greatly expanding the application range of the equipment. When the movable arm rotates, the moving frame rotates synchronously, ensuring that the machining component is always aligned with the workpiece, avoiding deviations caused by angle changes, and further simplifying the operation process.

[0020] Combination Figures 1-4 This utility model discloses a CNC radial drilling machine with multi-angle guide rail adjustment, including a base 1, a processing table 11 on the base 1, the processing table 11 being movable along the base 1 to adjust the position of the workpiece, a turntable 12 being fixedly connected to one end of the upper surface of the base 1, a guide column 13 being provided on the turntable 12, a lifting plate 2 being sleeved on the guide column 13, a limit plate 14 being fixedly connected to the upper end of the guide column 13, a first motor 141 being provided at one end of the limit plate 14, a threaded rod 142 being fixedly connected to the output end of the first motor 141, the threaded rod 142 engaging with the lifting plate 2, the first motor 141 driving the threaded rod 142 to rotate, controlling the lifting plate 2 to move up and down.

[0021] A first guide rail adjustment assembly is provided on one side of the lifting plate 2. The lifting plate 2 is connected to the movable arm 3 through the first guide rail adjustment assembly. The first guide rail adjustment assembly includes an annular guide rail 21 and a first worm gear 22 fixedly connected to the lifting plate 2. There are two annular guide rails 21, which are fixedly connected to each other through the first worm gear 22. The first guide rail adjustment assembly also includes a guide ring 31 fixedly connected to the movable arm 3 and a first worm gear 32 installed on the guide ring 31. The guide ring 31 is sleeved with the annular guide rail 21, and the guide ring 31 is connected to the movable arm 3 by a shaft. The first worm gear 32 is connected to the first worm gear 32, and a second motor 321 is fixedly connected to one end of the first worm gear 32. When the second motor 321 works, it drives the first worm gear 32 to rotate. The first worm gear 32 meshes with the first worm wheel 22. The first worm wheel 22 remains stationary. The rotating first worm gear 32 rotates around the first worm wheel 22, which drives the guide ring 31 to rotate around the annular guide rail 21. The guide ring 31 drives the movable arm 3 to rotate, changing the angle between the movable arm 3 and the horizontal plane. The structure of the guide ring 31 and the annular guide rail 21 sleeved together improves the stability of the movable arm 3 when it rotates.

[0022] The upper surface of the movable arm 3 is provided with a toothed track 33. A movable frame 4 is sleeved on the movable arm 3. The movable arm 3 guides the movable frame 4. The movable frame 4 moves along the direction of the movable arm 3. When the movable arm 3 rotates, it drives the movable frame 4 to rotate synchronously. A drive gear 41 is provided on the movable frame 4. The drive gear 41 meshes with the toothed track 33. The drive gear 41 drives it to rotate through a handwheel. The movable frame 4 moves along the toothed track 33.

[0023] A second guide rail adjustment assembly is provided on the lower surface of the movable frame 4, and a processing assembly 5 is connected to the second guide rail adjustment assembly. The second guide rail adjustment assembly includes a semi-circular guide rail 42 and a second worm gear 43 fixedly connected to the lower surface of the movable frame 4. Both ends of the second worm gear 43 are fixedly connected to the semi-circular guide rail 42. The second worm gear 43 is also designed as a semi-cylindrical structure to facilitate a tight connection with the movable frame 4. The second guide rail adjustment assembly also includes a slide bar 51 and a second worm 52 connected to the processing assembly 5. The slide bar 51 is movably connected to the semi-circular guide rail 42. The slide bar 51 moves within the semi-circular guide rail 42 and cannot disengage from it. The processing component 5 is connected to the semi-circular guide rail 42 via the slide bar 51. The second worm 52 meshes with the second worm wheel 43. One end of the second worm 52 is connected to a third motor 521, which drives the second worm 52 to rotate. The position of the second worm wheel 43 is fixed, causing the second worm 52 to rotate along the second worm wheel 43, thereby adjusting the angle of the processing component 5. The second worm wheel 43 is perpendicular to the axis of the first worm wheel 22, enabling multi-directional angle adjustment of the processing component 5.

[0024] The processing component 5 includes an electric drill motor 53 and an electric drill bit 54. The electric drill motor 53 drives the electric drill bit 54 to work and drill holes in the workpiece.

[0025] Working process: The workpiece to be processed is fixed on the processing table 11. By moving the processing table 11, the position of the workpiece can be adjusted. The guide column 13 supports the lifting plate 2. The first motor 141 drives the threaded rod 142 to rotate, causing the lifting plate 2 to move up and down along the guide column 13, adjusting the processing height of the electric drill bit 54. The operator can rotate the drive gear 41 by rotating the handwheel to move the moving frame 4 back and forth along the movable arm 3. When the second motor 321 drives the first worm 32 to rotate, since the first worm wheel 22 is fixed, the first worm 32 rotates around the first worm wheel 22, thereby driving the guide ring 31 and the movable arm 3 to rotate around the annular guide rail 21. The rotation allows the movable arm 3 to change its angle relative to the horizontal plane. The third motor 521 drives the second worm 52 to rotate. Since the position of the second worm wheel 43 is fixed, the second worm 52 will rotate along the second worm wheel 43, thereby driving the processing component 5 to adjust its angle. The second worm wheel 43 and the first worm wheel 22 are arranged perpendicularly to each other, so that the processing component 5 can achieve precise angle adjustment in multiple directions. In addition, when the movable arm 3 rotates, the moving frame 4 will rotate synchronously to ensure that the processing component 5 is always aligned with the workpiece. After the angle is adjusted, the electric drill motor 53 is started, and the electric drill bit 54 starts to work, precisely drilling holes in the workpiece according to the predetermined position and angle.
