Description

Technical Field

[0001] The utility model relates to the technical field of punching equipment, in particular to a punching device with adjustable angle. Background Art

[0002] In the process of machining mechanical parts, drilling operations are required. In most cases, automatic drilling or reaming equipment is used in the prior art. The equipment includes one or more drilling or reaming heads, which can improve production efficiency. However, due to its large size, the above-mentioned drilling equipment is not fully applicable to the inner wall hole opening processing of some special parts. In particular, the internal space of special parts is narrow and irregular, which makes the working space of the larger drilling equipment small. Only electric drills are allowed to enter the working space, and personnel cannot fully enter. It is inconvenient to exert force when using the electric drill, and it cannot ensure that the drill bit is perpendicular to the drilled plane. It does not meet the requirements of safe operation and there are certain safety hazards. It also cannot ensure the verticality of the hole, resulting in the drilled hole failing to meet the use requirements, causing the opened hole to fail to meet the design requirements, which brings great difficulties to the operator.

[0011] In some technical solutions of the present utility model, an indicator plate connected to the outer side wall of the support arm is sleeved thereon, and a scale plate is provided on the body of the third cylinder.

[0021] Example

[0022] Please refer to Figure 1-Figure 3 shown.

[0023] The utility model provides a punching device with adjustable angle, such as Figure 1 、 Figure 2 As shown, it includes a mounting frame 2 mounted on the free end of the robotic arm, the mounting frame 2 and the free end of the robotic arm are connected by bolts, and a mounting groove is opened on the side wall of the mounting frame 2 along its extension direction, the mounting groove is long and its cross section is rectangular; a support arm 7 in the shape of a hollow tube is installed in the mounting groove, and its cross section is rectangular; a fixing seat 9 is installed on the free end of the support arm 7, and a through groove is opened in the middle of the fixing seat 9, and a second drive motor 8 is installed in the through groove, and the second drive motor 8 is fixed in the through groove by bolts, and a drill bit 14 is installed on the output end of the second drive motor 8. The drill bit 14 can be removed from the output end of the second drive motor 8 for easy later maintenance, and an adjustment component on the mounting frame 2 for adjusting the movement of the support arm 7 relative to the mounting frame 2 can adjust the relative position of the drill bit 14 relative to the workpiece 1 in a wider range. Through the above structure, the support arm 7 can also be extended into the narrow space inside the workpiece 1, so as to facilitate the adjustment of the drilling angle of the drill tool by the robotic arm; and ensure that the drill bit is perpendicular to the drilled plane and the verticality of the drilled hole is ensured, thereby improving the hole quality required for the workpiece 1.

[0024] In some technical solutions of the present invention, the adjustment assembly includes a mounting base 4 slidably disposed within a mounting groove. The mounting base 4 has a rectangular cross-section, with the outer wall of the mounting base 4 abutting against the inner wall of the mounting groove. A support arm 7 is connected to the mounting base 4. A first cylinder 3 connected to the mounting base 4 is disposed within the mounting groove. The main body of the first cylinder 3 is rotatably disposed on the inner wall of the mounting groove via an ear piece and a pin, and the telescopic end of the first cylinder 3 is fixedly connected to the mounting base 4 via a bolt. The above structure enables the mounting base 4 to drive the support arm 7 to reciprocate in the direction of the mounting groove, ensuring that the drilling depth of the drill bit 14 in the workpiece 1 is adjustable to accommodate drilling requirements of different depths.

[0025] Preferably, a guide groove may be provided on the inner wall of the mounting groove, and a sliding block fixedly connected to the mounting seat 4 by bolts is slidably provided in the guide groove.

[0026] In some technical solutions of the present invention, a rectangular telescopic arm 16 is slidingly provided in the support arm 7, and the telescopic arm 16 is connected to the fixed seat 9 by bolts. A third cylinder 15 connected to the fixed seat 9 is provided in the support arm 7. In this way, when the telescopic end of the third cylinder 15 gradually moves out of its body, the telescopic arm 16 will gradually extend out of the support arm 7, thereby extending the movement distance of the support arm 7 in the narrow space of the workpiece 1, thereby extending the drill bit 14 to the specified position, and performing drilling operations deeper in the narrow space of the workpiece 1, thereby improving the adaptability of the device.

[0027] In some technical solutions of the present invention, a first drive motor 5 is mounted within the mounting base 4, the output end of which is connected to the body of a third cylinder 15; the third cylinder 15 is rotatably mounted within the support arm 7. This arrangement allows the mounting base 9 to perform circular motion within the support arm 7, driven by the first drive motor 5. This allows the drill bit to adjust its deflection angle within the narrow space of the workpiece 1, allowing drilling operations to be performed in particularly difficult locations.

[0028] In some technical solutions of the present invention, a coupling 11 is provided between the output end of the first drive motor 5 and the body of the third cylinder 15. This arrangement facilitates disassembly and installation of the first drive motor 5 and the third cylinder 15 during subsequent maintenance, thereby improving the disassembly and maintenance efficiency of the structure.

[0029] In some technical solutions of the present invention, a second cylinder 6 is provided on the side wall of the mounting frame 2, and a support arm 7 is provided with a sliding sleeve 10 connected to the free end of the second cylinder 6. The support arm 7 is hingedly connected to the mounting frame 2. This allows the second cylinder 6 to push the support arm 7 upward or downward on the mounting frame 2, further adjusting the deflection angle of the drill bit within the narrow space of the workpiece 1, allowing drilling operations to be performed in more difficult locations.

[0030] In some technical solutions of the present invention, an indicator disk 12 connected to the outer wall of the support arm 7 is provided, and a scale disk 13 is provided on the body of the third cylinder 15 for observing the deflection angle of the fixed seat 9 relative to the support arm 7, which is convenient for the later operator to perform actual operations and adjust the relative position of the drill bit 14 and the hole to be drilled.

[0031] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
