Description

Technical Field

[0001] This utility model relates to the field of magnetic drill technology, and in particular to a magnetic drill with controllable processing depth. Background Technology

[0002] In the field of metal processing, especially in complex industries with extremely high precision requirements such as steel structure, shipbuilding, equipment manufacturing, bridge engineering and wind power, drilling is a crucial process. Traditional drilling methods, such as using electric drills or stationary drilling machines, often fall short when dealing with large, heavy or difficult-to-fix workpieces.

[0003] For example, patent CN222843201U, entitled "A Magnetic Drill with Controllable Machining Depth," with an authorization announcement date of May 9, 2025, includes a mounting box. A fixed box is mounted on one side of the outer wall of the mounting box, and a movable box is located at the bottom of the fixed box. A rotating head is located on the bottom surface of the movable rod. A drive mechanism is located inside the mounting box, which drives the movable box to move up and down. Through the adjustment and movement mechanisms, workers can clearly observe and precisely control the drilling depth of the rotating head using scale lines, reducing manual intervention during the drilling process. Excessive or insufficient drilling depth can lead to workpiece damage or safety accidents. Precise control of the drilling depth can effectively avoid these problems, improving work safety. Simultaneously, precise control of the drilling depth reduces the scrap rate and minimizes material waste and rework costs caused by improper drilling depth.

[0004] The shortcomings of existing technologies are that traditional magnetic drills mostly rely on manual experience or simple mechanical limiting devices to control the drilling depth. This method not only has limited accuracy but is also complicated to operate, making it difficult to meet the needs of high-precision machining. Therefore, a magnetic base drill with controllable machining depth is proposed to solve the above problems. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Reference Figure 1-5 A magnetic drill with controllable processing depth includes a magnetic base 1; a support frame 2 is fixedly connected to the top of the magnetic base 1, and a drill body 4 is provided at one end of the support frame 2; the support frame 2 includes a support arm 21, and a slider 22 is slidably provided between the two support arms 21. A toothed groove 23 is provided at one end of the slider 22, and the toothed groove 23 meshes with a gear shaft 24 fixedly connected to a rotating shaft 25. A rotating handle 5 is fixedly connected to one end of the rotating shaft 25 through the support arm 21; it also includes a limiting component 3, which is provided on the support frame 2, and the moving distance of the drill body 4 is preset by the limiting component 3.

[0029] Specifically, the magnetic base 1 has a rectangular structure, and a support frame 2 is fixedly connected to the magnetic base 1. A slider 22 is slidably installed in the support arm 21 symmetrically arranged in the support frame 2. The drill body 4 is fixedly connected to the slider 22. By manually rotating the rotating handle 5, the rotating shaft 25 and the gear shaft 24 fixed to it are driven to rotate. The gear groove 23 of the gear shaft 24 is opened on the slider 22, so that the slider 22 drives the drill body 4 to move in a directional manner under the transmission of the rotating handle 5 to complete the drilling of the drill body 4. The limiting component 3 set on the support frame 2 is used to limit the distance of the directional movement of the drill body 4, so that the drilling depth can be controlled according to actual needs.

[0030] The limiting component 3 includes a pull rod 31, which passes through the support frame 2 and is fixedly connected to a stop post 32. Limiting strips 33 are provided at both ends of the stop post 32 and are fixedly connected to the slider 22. A limiting strip 33 is movably provided at the top of the pull rod 31, and scale strips 34 are symmetrically fixedly connected to both ends of the limiting strip 33. Scale grooves 341 are symmetrically provided at both ends of the scale strips 34. Gear blocks 347 are symmetrically provided at the bottom of the scale strips 34, and a rack 35 is provided at one end of each gear block 347 and is fixedly connected to... On the support arm 21; a brake bar 344 is provided at the top of the gear block 347, and a guide post 343 is symmetrically provided through the top of the brake bar 344. A fixed seat 342 is fixedly connected to one end of the guide post 343, and the fixed seat 342 is fixedly connected to the scale bar 34; a support spring 346 is fixedly connected to the bottom end of the fixed seat 342, and the bottom end of the support spring 346 is fixedly connected to the brake bar 344; a connecting rod 345 is fixedly connected to one end of the brake bar 344, and a handle bar 348 is fixedly connected to the top of the connecting rod 345.

[0031] Specifically, racks 35 fixed to the support arm 21 are symmetrically distributed on both sides of the scale bar 34. The gear block 347 rotatably connected to the bottom end of the scale bar 34 meshes with the rack 35. When the handle 348 is manually pulled, it moves upward. The handle 348 drives the connecting rod 345 to move in a specific direction. The brake bar 344 fixed to the bottom end of the connecting rod 345 compresses the support spring 346 and separates from the gear block 347, pushing the limit bar 33 to drive the scale bar 34 to move downward, so that the limit bar 33 penetrates into the scale bar 34. The pull rod 31 drives the abutment 32 to move. The limiting block 26 fixed on the slider 22 is used to limit the position of the slider 22 and the abutment 32. The limiting cap fixed on the top of the pull rod 31 is used to limit the position of the pull rod 31 on the limiting strip 33. This allows the movement distance of the limiting strip 33 to be controlled by the scale groove 341 in the scale strip 34. The abutment 32 controls the movement distance of the drill body 4 through the limiting strip 33. This device has a simple structure, strong practicality, and is worth promoting widely.

[0032] Working principle: Manually rotating the rotating handle 5 drives the rotating shaft 25 and the gear shaft 24 to rotate. The meshing tooth groove 23 of the gear shaft 24 is opened on the slider 22. Under the transmission of the rotating handle 5, the slider 22 drives the drill body 4 to move in a directional manner. The limiting component 3 set on the support frame 2 limits the distance of the directional movement of the drill body 4. Among them, the rack 35 on the support arm 21 is symmetrically distributed on both sides of the scale bar 34. The gear block 347 rotatably connected to the bottom end of the scale bar 34 meshes with the rack 35. Manually pulling the handle 348 moves it upward. The handle 348 drives the connecting rod 345 to move in a directional manner. The brake bar 344 fixed to the bottom end of the connecting rod 345 squeezes out. The pressure support spring 346 separates from the gear block 347, pushing the limiting bar 33 to drive the scale bar 34 downward, causing the pull rod 31 passing through the limiting bar 33 to drive the abutment 32 to move. The limiting block 26 fixed on the slider 22 is used to limit the position of the slider 22 and the abutment 32. The limiting cap fixed on the top of the pull rod 31 is used to limit the position of the pull rod 31 on the limiting bar 33, so that the distance of movement of the limiting bar 33 can be controlled by the scale groove 341 in the scale bar 34, and the distance of movement of the abutment 32 can be controlled by the limiting bar 33 to control the distance of movement of the drill body 4, so that the drilling depth can be controlled according to actual needs.
