Description

Technical Field

[0001] The utility model relates to the technical field of magnetic base drill equipment, in particular to a magnetic base drill with controllable processing depth. Background Art

[0002] In the field of metal processing, especially in complex and high-precision industries such as steel structure, shipbuilding, equipment manufacturing, bridge engineering, and wind power, drilling is a crucial process. Traditional drilling methods, such as using hand drills or fixed drilling machines, often seem to be inadequate when facing large, heavy or difficult-to-fix workpieces. These traditional tools are difficult to ensure the consistency of processing depth during the drilling process, and the operation is complicated, labor-intensive, and work efficiency is low.

[0003] In order to overcome these limitations, an innovative tool, the magnetic drill, has gradually appeared on the market. The magnetic drill, also known as the magnetic base drill, magnet drill, and magnet drill, works on the electromagnetic principle. When powered on, the electromagnet on the base of the magnetic drill generates a strong magnetic field, which firmly adheres to the surface of the steel part. This feature enables the magnetic drill to perform stable and precise drilling operations on steel structures without the need for additional fixtures. However, although the magnetic drill has made significant progress in adsorption and stability, there are still certain challenges in controlling the processing depth. Traditional magnetic drills mostly rely on manual experience or simple mechanical limit devices to control the drilling depth. This method not only has limited accuracy, but also is complicated to operate and is difficult to meet the needs of high-precision processing. Therefore, a magnetic base drill with controllable processing depth is proposed to solve the above problems. Utility Model Content

[0023] The present application provides a magnetic drill with controllable processing depth, which is mainly used to solve the problem of how to control the drilling depth, and provides the following technical solutions. Figure 1-Figure 6 Make a detailed description:

[0024] Embodiment 1:

[0025] A magnetic drill with controllable processing depth comprises an installation box 1, a fixed box 2 is installed on one side of the outer wall of the installation box 1, a movable box 3 is arranged at the bottom of the fixed box 2, a rotary head 4 is arranged on the bottom surface of the movable box 3, a driving mechanism 5 is arranged inside the installation box 1, the driving mechanism 5 is used to drive the movable box 3 to move up and down, and its specific components are: it comprises an electric push rod 501 installed on the inner top wall of the fixed box 1, a connecting hole is opened on the bottom surface of the fixed box 2, the output end of the electric push rod 501 passes through the connecting hole and a movable rod 502 is fixedly installed on the end, the bottom end of the movable rod 502 is fixedly connected to the movable box 2, and adjustment mechanisms 6 are arranged on both sides of the installation box 1, and the adjustment mechanism 6 is used to adjust the descending distance of the rotary head 4, and its specific components are: it comprises an L-shaped plate 601 fixedly connected to both sides of the movable rod 502, guide rods 602 are symmetrically installed on both sides of the outer wall of the installation box 1, and the outer wall of the guide rod 602 is slidably connected with A connecting ring 603, the outer wall of the connecting ring 603 is fixedly connected to the L-shaped plate 601, a first pointer 604 is fixedly installed on one side of the outer wall of the connecting ring 603, a movable ring 605 is arranged on the outer wall of the guide rod 602 below the connecting ring 603, a second pointer 606 is arranged on one side of the outer wall of the movable ring 605, a connecting groove is opened on one side of the top surface of the movable ring 605 and a pressure sensor 607 is installed on the inner bottom wall of the connecting groove, a resistance block 608 is installed on one side of the bottom surface of the connecting ring 603, a moving mechanism 8 is arranged on the top of the installation box 1, the moving mechanism 8 is used to drive the connecting ring 603 to move up and down, the pressure sensor 607 is electrically connected to the electric push rod 501, display panels are symmetrically installed on both sides of the outer wall of the installation box 1 and the outer wall of the display panel is marked with scale lines 9, a rotating mechanism 7 is arranged inside the movable box 3, the rotating mechanism 7 is used to drive the rotating head 4 to rotate, and a handle is installed on one side of the outer wall of the installation box 1.

[0026] The specific operation method and working principle of the device are as follows: during the working process, the staff turns on the electric push rod 501, so that the electric push rod 501 drives the movable rod 502 and the rotating head 4 to move downward until the rotating head 4 conflicts with the object, and then observes the scale line 9 pointed to by the first pointer 604 at this time. Then the staff can process the hole turning distance as needed, and then drive the second pointer 606 to move up and down through the moving mechanism 8. Here, the scale line 9 pointed to by the second pointer 606 minus the scale line 9 pointed to by the first pointer 604 is the distance of this construction processing, so that the staff can intuitively control the processing depth. When the staff turns on the electric push rod 501 to drive the movable rod 502 and the movable box 3 to move downward, the staff can turn on the motor 701 to drive the rotating head 4 to rotate and turn the hole in the object. At this time, the connecting ring 603 will move downward until the connecting ring 603 conflicts with the movable ring 605. At this time, the conflict block 608 presses on the pressure sensor 607, and the pressure sensor 607 triggers a signal to the electric push rod 501, causing the electric push rod 501 to stop working.

[0027] Embodiment 2:

[0028] like Figure 2 , Figure 3 and Figure 5 As shown, in some embodiments, the moving mechanism 8 includes a first screw 801 rotatably connected to the upper and lower sides of the installation box 1, the outer wall of the first screw 801 is threadedly connected to a nut 802, and the outer wall of the nut 802 is symmetrically installed with a limit plate 803, and rectangular holes are symmetrically opened on both sides of the outer wall of the installation box 1, and the limit plate 803 is slidably connected to the rectangular hole. The end of the limit plate 803 away from the nut 802 passes through the rectangular hole and the end is fixedly connected to the movable ring 605. The rotating mechanism 7 includes a motor 701 fixedly installed on the inner top wall of the movable box 3, the output end of the motor 701 is installed with a movable rod 502, and the outer wall of the movable rod 502 is slidably connected with a connecting sleeve 702, and the bottom of the connecting sleeve 702 is fixedly connected to the rotating head 4, the outer wall of the connecting sleeve 702 is threadedly connected with a second screw 703, and the end of the movable rod 502 is opened with a threaded hole compatible with the screw, and a handle is fixedly installed on one end of the second screw 703 and the outer wall of the handle is provided with a rubber sleeve.

[0029] The operating principle and working method of the moving mechanism 8 are as follows: during operation, the staff can rotate the first screw 801 to drive the nut 802 to move up and down, thereby driving the movable ring 605 to move upward. In addition, the staff can also turn on the motor 701 to drive the movable rod 502 to rotate, thereby driving the connecting sleeve 702 and the rotating head 4 to rotate and make holes in the object. It should be noted that the staff can rotate the second screw 703 to disengage the second screw 703 from the movable rod 502 and the connecting sleeve 702, thereby facilitating the staff to replace the rotating head 4.

[0030] Working step one: during the working process, the staff can place the rotating head 4 above the construction object, and then the staff can turn on the electric push rod 501, so that the electric push rod 501 drives the movable rod 502 and the rotating head 4 to move downward until the rotating head 4 collides with the object, and then observes the scale line 9 pointed to by the first pointer 604 at this time, and then the staff can process the distance of the rotary hole as needed, and then the staff can rotate the first screw 801, so that the nut 802 moves up and down, thereby driving the limit plate 803 and the movable ring 605 to move upward. Here, the scale line 9 pointed to by the second pointer 606 minus the scale line 9 pointed to by the first pointer 604 is the distance of this construction processing, which can facilitate the staff to intuitively control the processing depth.

[0031] Working step two: when the staff turns on the electric push rod 501 to drive the movable rod 502 and the movable box 3 to move downward, the motor 701 can be turned on to drive the movable rod 502 to rotate, thereby driving the connecting sleeve 702 and the rotating head 4 to rotate and turn the object. At this time, the connecting ring 603 will move downward until the connecting ring 603 conflicts with the movable ring 605. At this time, the conflict block 608 presses on the pressure sensor 607, and the pressure sensor 607 triggers a signal to the electric push rod 501, causing the electric push rod 501 to stop working, thereby stopping the rotating head 4 from continuing to move downward, and realizing depth-controlled processing and turning holes.

[0032] Work step three: After the work is completed, if the rotor 4 needs to be replaced, the staff can rotate the second screw 703 to make the second screw 703 disengage from the movable rod 502 and the connecting sleeve 702, and then put on a new rotor 4, so that the screw passes through the connecting sleeve 702 and the movable rod 502, thereby replacing the rotor 4.

[0033] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
