Description

Technical Field

[0001] This utility model relates to the field of CNC drilling machine technology, specifically to an automatic material clamping and positioning device for CNC drilling machines. Background Technology

[0002] Automatic material clamping and positioning devices for CNC drilling machines are mainly used for drilling, reaming, boring, and tapping. They are numerically controlled hole-making machine tools primarily used for drilling. Based on their layout and functional characteristics, automatic material clamping and positioning devices for CNC drilling machines can be categorized into those for CNC vertical drilling machines, drilling centers, CNC drilling machines for printed circuit boards, CNC deep hole drilling machines, and other large CNC drilling machines.

[0003] Existing automatic material clamping and positioning devices for CNC drilling machines require fixing the material's position during the material clamping process to ensure drilling accuracy. However, these devices often require operators to rotate a screw to move the clamping plate and fix the material's position, increasing the operator's workload. Furthermore, once the material is clamped and fixed on the CNC drilling machine table, the angle cannot be adjusted. For irregular workpieces, adjusting the angle requires the operator to loosen the clamping components, manually rotate the workpiece, and re-fix it. Manual adjustment can easily lead to inaccurate positioning, affecting drilling accuracy. Therefore, we propose a new automatic material clamping and positioning device for CNC drilling machines.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] Please see Figure 1-3 This utility model provides a technical solution: an automatic positioning device for material clamping of a CNC drilling machine, including a base 1, with non-through mounting grooves 2 symmetrically opened on both sides of the top of the base 1, a moving component 3 provided in the inner cavity of the mounting groove 2, a vertical plate 4 fixedly connected to the top of the moving component 3, non-through sliding grooves 5 respectively opened on the opposite side of the two vertical plates 4, a lifting component 6 provided in the inner cavity of the sliding groove 5, mounting plates 7 symmetrically provided on the two lifting components 6, a rotating component 8 provided on one side of one mounting plate 7, a clamping plate 9 fixedly connected to one side of the rotating component 8, and a clamping plate 9 rotatably connected to one side of the other mounting plate 7 through a bearing.

[0020] Specifically, such as Figure 2As shown, the moving component 3 includes a motor 3.1, a threaded rod 3.2, and a moving block 3.3. The threaded rod 3.2 is rotatably connected to the inner wall of the mounting groove 2 via a bearing. The motor 3.1 is fixedly connected to one side of the base 1. The output end of the motor 3.1 passes through the inner cavity of the mounting groove 2 and is fixedly connected to one end of the threaded rod 3.2. The moving block 3.3 is threadedly engaged with the threaded rod 3.2, and a vertical plate 4 is fixedly connected to the top of the moving block 3.3. When clamping and fixing the material, the height of the clamping plate 9 is first adjusted by the lifting component 6, and then the motor 3.1 is started, driving the threaded rod 3.2 to rotate. This causes the two moving blocks 3.3 to drive the vertical plate 4 and the clamping plate 9 on it to fix the material from both sides. This method is suitable for materials of different sizes and provides a stable clamping and fixing of the material.

[0021] Specifically, such as Figure 2 , Figure 3 As shown, the lifting assembly 6 includes a second motor 6.1, a second threaded rod 6.2, and a second moving block 6.3. The second threaded rod 6.2 is rotatably connected to the inner cavity of the slide groove 5 via a bearing. The second motor 6.1 is fixedly connected to the top of the vertical plate 4, and the output end of the second motor 6.1 passes through the inner cavity of the slide groove 5 and is fixedly connected to the top of the second threaded rod 6.2. The second moving block 6.3 is slidably sleeved on the second threaded rod 6.2 via threaded engagement, and mounting plates 7 are fixedly connected to opposite sides of the two second moving blocks 6.3. When clamping and fixing the material begins, the second motor 6.1 is started according to the size of the material, driving the second threaded rod 6.2 to rotate, thereby driving the second moving block 6.3 to move. When the second moving block 6.3 moves the mounting plate 7 and its clamping plate 9 to the appropriate position, the second motor 6.1 is stopped, and the material can be clamped. This allows for adjustment of the height of the clamping plate 9 according to the size of the material, making the clamping more stable.

[0022] Specifically, such as Figure 2 , Figure 3As shown, the rotating assembly 8 includes a motor 8.1, a driving gear 8.2, and a driven gear 8.3. The driven gear 8.3 is rotatably connected to the middle of one side of the mounting plate 7 via a bearing. The driving gear 8.2 is rotatably connected to one side of the mounting plate 7 via a bearing, and the driving gear 8.2 and the driven gear 8.3 are meshed together. The motor 8.1 is fixedly connected to the other side of the mounting plate 7. The output end of the motor 8.1 passes through the mounting plate 7 and is fixedly connected to the driving gear 8.2. One side of the driven gear 8.3 is fixedly connected to the clamping plate 9. When the material is irregularly shaped and needs to be drilled on one side, or when multiple sides of the material need to be drilled, the material is first clamped by the moving component 3, and then the lifting component 6 is activated to lift the material away from the surface of the base 1. At this time, the motor 8.1 is activated to drive the drive gear 8.2 to rotate, which in turn causes the driven gear 8.3 to drive the clamping plate 9 to rotate. Since the two clamping plates 9 clamp the material, the material and the other clamping plate 9 also rotate. When the rotation reaches the surface to be drilled, the motor 8.1 is stopped, and the lifting component 6 is activated again to make the material fall to the top of the base 1, so that the drilling work on this surface can be carried out.

[0023] Specifically, such as Figure 3 As shown, the clamping plate 9 is circular. The circular clamping plate 9 facilitates the flipping of the material with the rotating component 8. Rubber anti-slip pads 10 are fixedly connected to the opposite sides of the two clamping plates 9. The rubber anti-slip pads 10 can effectively increase the friction between the clamping plate 9 and the material, making the clamping more stable.

[0024] It should be noted that this utility model is an automatic positioning device for clamping materials on a CNC drilling machine. When clamping and fixing the material, motor 6.1 is started according to the size of the material, driving the threaded rod 6.2 to rotate, thereby driving the moving block 6.3 to move. When the moving block 6.3 drives the mounting plate 7 and the clamping plate 9 on it to a suitable position, motor 6.1 is stopped, and the material can be clamped. It is convenient to adjust the height of the clamping plate 9 according to the size of the material, so as to make the clamping more stable. Then, motor 3.1 is started again, driving the threaded rod 3.2 to rotate, so that the two moving blocks 3.3 drive the vertical plate 4 and the clamping plate 9 on it to fix the material from both sides. It is suitable for materials of different sizes and heights, and the clamping and fixing of the material is stable.

[0025] When the material is irregularly shaped and needs to be drilled on one side, or when multiple sides of the material need to be drilled, the material is first clamped by the moving component 3, and then the lifting component 6 is activated to lift the material away from the surface of the base 1. At this time, the motor 8.1 is activated to drive the drive gear 8.2 to rotate, which in turn causes the driven gear 8.3 to drive the clamping plate 9 to rotate. Since the two clamping plates 9 clamp the material, the material and the other clamping plate 9 also rotate. When the rotation reaches the surface to be drilled, the motor 8.1 is stopped, and the lifting component 6 is activated again to make the material fall to the top of the base 1, so that the drilling work on this surface can be carried out.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
