Description

Technical Field

[0001] This utility model relates to the field of drilling technology, and in particular to a drilling device for intelligent CNC machine tools. Background Technology

[0002] CNC machine tools, short for numerical control machine tools, are automated machine tools equipped with a program control system. This control system can logically process programs with control codes or other symbolic instructions, decode them, represent them with coded numbers, input them to the CNC device through an information carrier, and after processing, the CNC device sends out various control signals to control the machine tool's movements, automatically machining parts according to the shape and dimensions required by the drawings.

[0003] However, in practical applications, before drilling multiple holes at equal intervals on the outer side of a circular plate, it is necessary to use measuring tools to mark the circular plate with lines. When drilling, these marked positions need to be aligned with the drilling position one by one, which takes a long time and is prone to deviation between the marked position and the drilling position, resulting in drilling failure of the circular plate. Therefore, we disclose a drilling device for intelligent CNC machine tools. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a drilling device for intelligent CNC machine tools to solve the problem of easy failure when drilling circular plates.

[0005] To achieve the above objectives, this utility model provides a drilling device for an intelligent CNC machine tool, comprising a machine tool frame, a rotating shaft rotatably connected to the top of the machine tool frame, a placement platform fixedly connected to one end of the rotating shaft extending outside the machine tool frame, a plurality of second limiting grooves equidistantly formed on the outer wall of the placement platform, a second moving groove formed at one end of the machine tool frame, a second spring fixedly connected to the inner wall of the second moving groove, a limiting frame fixedly connected to one end of the second spring, a second limiting rod fixedly connected to one end of the limiting frame extending out of the machine tool frame, the second limiting rod being movably engaged with the second limiting groove, and a drilling machine fixedly connected to the top of the machine tool frame, the drilling machine being located above the placement platform.

[0006] Preferably, a scale groove is provided on one side of the second limiting groove, the second moving groove and the limiting frame are both L-shaped, and a handle is fixedly connected to one end of the limiting frame that extends to the outside of the machine tool frame.

[0007] Preferably, the rotating shaft is T-shaped and the placement platform is circular.

[0008] Preferably, a first movable groove is provided in the middle of the top of the machine tool frame, and a cover plate is fixedly connected to the middle of the first movable groove. The top surface of the cover plate and the placement table are located on the same plane. A rotating cylinder is rotatably connected to the lower end of the cover plate. Both ends of the rotating cylinder are threadedly connected to screws. A connecting plate is fixedly connected to one end of the screws. A limit plate is fixedly connected to one end of the connecting plate extending to the outside of the machine tool frame. A first gear is fixedly connected to the outer wall of the rotating cylinder. A second gear is meshed at one end of the first gear. A belt assembly is fixedly sleeved in the middle of the second gear. A connecting shaft is fixedly sleeved in the middle of the belt assembly. One end of the connecting shaft passes through the placement table and is fixedly connected to a turntable outside the placement table. A first spring is fixedly connected to one end of the turntable. A first limit rod is fixedly connected to one end of the first spring. A plurality of first limit grooves are provided on one side of the placement table. The first limit rod passes through the turntable and is movably engaged with the first limit groove.

[0009] Preferably, the first limiting rod is a T-shaped rod, the first moving groove and the connecting plate are T-shaped, and the limiting plate is an arc-shaped plate.

[0010] Preferably, both the second gear and the belt assembly are rotatably connected to the placement platform.

[0011] The beneficial effects of this utility model are as follows: The drilling plate is placed on the top of the placement table, and the machine tool frame restricts the rotation position of the placement table through the rotating shaft, thereby restricting the position of the drilling plate placed on the top of the placement table. The rotation angle of the placement table can be controlled according to the second limiting groove, so that the placement table drives the drilling plate to rotate at equal angles, thereby allowing the drilling plate to drill multiple holes distributed at equal angles. This avoids drilling deviation caused by manually marking lines on the surface of the drilling plate and then aligning them one by one during drilling, thereby improving the drilling success rate of the drilling plate.

[0012] The first movable groove restricts the movement of the connecting plate, thereby limiting the rotation of the screw. When the drum rotates, it drives the screw to move. When the turntable rotates, it drives the belt assembly to rotate through the connecting shaft. The belt assembly drives the drum to rotate through the second gear and the first gear. The two screws drive the two limiting plates to move synchronously through the connecting plate and fit against the drilling plate at the top of the placement platform. This also makes the drilling plate located at the center of the placement platform, so that the drilling plate and the placement platform rotate concentrically. This ensures that the drilling plate and the placement platform rotate at the same angle at the same time, restricts the position of the drilling plate, ensures the stability of the drilling plate when drilling, and improves the drilling success rate.

The drilling machine 23 is located above the placement table 3. The second limiting groove 22... A graduated groove is provided on one side of the machine tool frame 1. The second moving groove 18 and the limiting bracket 20 are both L-shaped. A handle is fixedly connected to one end of the limiting bracket 20 extending to the outside of the machine tool frame 1. The rotating shaft 2 is T-shaped, and the placement table 3 is a circular table. In use, the drilling plate is placed on the top of the placement table 3. The rotating shaft 2 is rotatably connected to the top of the machine tool frame 1. The placement table 3 is fixedly connected to one end of the rotating shaft 2 extending to the outside of the machine tool frame 1, so that the machine tool frame 1 restricts the rotation position of the placement table 3 through the rotating shaft 2, thereby restricting the position of the drilling plate placed on the top of the placement table 3. Several second limiting grooves 22 are equidistantly provided in a ring on the outer wall of the placement table 3. A second moving groove 18 is provided at one end of the machine tool frame 1.

This avoids drilling deviations caused by manually marking lines on the drilling plate surface and then aligning them one by one during drilling, thus improving the drilling success rate of the drilling plate. The second moving groove 18 and the second spring 19 restrict the movement of the limiting frame 20, thereby limiting the position of the second limiting rod 21 through the limiting frame 20, allowing the second limiting rod 21 to... The second limiting groove 22 restricts the position of the placement table 3 after rotation, thereby making the rotation angle of the placement table 3 more stable when drilling holes in the drilling plate, improving the drilling success rate. A scale groove is opened on one side of the second limiting groove 22, making it easy for the operator to control the rotation angle. Since both the second moving groove 18 and the limiting frame 20 are L-shaped, the second moving groove 18 has a good position limiting effect on the limiting frame 20, which in turn makes the second limiting rod 21 better limit the position of the placement table 3.

The rotating shaft 2 is T-shaped and the placement table 3 is a circular platform, making the connection between the rotating shaft 2 and the machine tool frame 1 more stable.
