[0002] When machining holes on a vertical drilling machine, the alignment of the tool and the workpiece is achieved by moving the workpiece, which is obviously very inconvenient for some large and heavy workpieces. However, a radial drilling machine can use the position of the tool axis to achieve alignment, which greatly facilitates the machining of holes on large and heavy workpieces in single-piece and small-batch production.

[0003] Chinese Patent No. CN217941954U discloses a positioning and locking device for a radial drilling machine, including a base and a radial drilling machine, and a positioning and locking mechanism. The positioning and locking mechanism is provided at the base under the radial drilling machine. With the help of the positioning and locking mechanism at the base, there is a simple and effective positioning and locking structure at the base under the radial drilling machine. When the workpiece is processed at the base, it can be easily positioned and locked and is not easy to move, which facilitates the safe processing of the workpiece that is firmly locked at the base.

[0004] The positioning device for radial drilling machines described in the above patent has a complex structure and is inconvenient for changing workpieces, which affects work efficiency in actual use. Therefore, it does not meet the existing needs. In response, we have proposed a positioning and locking structure for radial drilling machines. Utility Model Content

The two ends of the sliding rod are fixedly connected to the top support plate and the positioning frame base, respectively, and the sliding rod passes through the spring pressure plate and is slidably connected to the spring pressure plate.

[0011] Preferably, the lower end of the spring rod extends into the interior of the electromagnet column and is fixedly connected to the electromagnet column, and the upper end of the spring rod is fixedly connected to the spring pressure plate, and the upper end surface of the spring pressure plate is provided with an anti-slip pad.

[0012] Preferably, a magnetic ring is provided on the lower end face of the spring pressure plate, and the electrodes of the electromagnet column are the same as the electrodes of the magnetic ring.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] To address the problems of complex structure, inconvenient workpiece replacement, and reduced work efficiency associated with existing radial drilling machine positioning devices, please refer to [the relevant documentation / reference]. Figure 1 - Figure 4 This embodiment provides the following technical solution:

[0023] A positioning and locking structure for a radial drilling machine includes a radial arm bracket 1 and a positioning frame base 5. A worktable 4 is installed below the radial arm bracket 1. Two positioning frame bases 5 are provided, and the two positioning frame bases 5 are respectively installed on both sides of the worktable 4.

[0024] An electromagnet column 503 is installed above the positioning frame base 5, and a spring pressure plate 502 is installed above the electromagnet column 503. A spring rod 504 is installed between the spring pressure plate 502 and the electromagnet column 503. During use, the positioning device adjusts the position of the two positioning frame bases 5 according to the size of the workpiece to adapt to different workpieces. The two ends of the workpiece are inserted into the spring pressure plates 502 on both sides and fixed by the spring rod 504.

[0025] A top support plate 501 is installed above the positioning frame base 5. A sliding rod 505 is installed at the lower outer end of the top support plate 501. The two ends of the sliding rod 505 are fixedly connected to the top support plate 501 and the positioning frame base 5, respectively. The sliding rod 505 passes through the spring pressure plate 502 and is slidably connected to the spring pressure plate 502.

[0026] The lower end of the spring rod 504 extends into the interior of the electromagnet column 503 and is fixedly connected to the electromagnet column 503. The upper end of the spring rod 504 is fixedly connected to the spring pressure plate 502. An anti-slip pad 506 is provided on the upper surface of the spring pressure plate 502. The anti-slip pad 506 further stabilizes the position of the workpiece and reduces the wear of the positioning structure.

[0027] A magnetic ring 508 is provided on the lower end face of the spring pressure plate 502. The electrodes of the electromagnet column 503 are the same as the electrodes of the magnetic ring 508. After the power is turned on, the like poles repel each other, pushing the electromagnet column 503 away from the top support plate 501 to perform locking. When the power is turned on, the electromagnet column 503 pushes the magnetic ring 508, causing the spring pressure plate 502 to press the workpiece and lock it quickly. The structure is simple, the position is stable, and it is easy to disassemble and assemble, so as to carry out continuous work and improve work efficiency.

[0028] Specifically, during use, the positioning device adjusts the positions of the two positioning frame bases 5 according to the size of the workpiece to adapt to different workpieces. The two ends of the workpiece are inserted above the spring pressure plates 502 on both sides and fixed by the spring rods 504. After the position is stable, the power supply of the electromagnet column 503 is turned on. The electromagnet column 503 pushes the magnetic ring 508, causing the spring pressure plates 502 to squeeze the workpiece and lock it quickly. The structure is simple, the position is stable, and it is easy to disassemble and assemble for continuous work and improve work efficiency.

[0029] To address the issues of poor positional stability and inconvenient operation in existing radial drilling machine positioning devices during practical use, please refer to... Figure 1 - Figure 3 This embodiment provides the following technical solution:

[0030] A lifting frame 2 is installed on one side of the rocker arm bracket 1. A mobile drilling rig 3 is set outside the lifting frame 2. The position of the drill bit of the mobile drilling rig 3 corresponds to the position of the positioning frame base 5. The processing work is carried out by adjusting the position of the lifting frame 2 and the mobile drilling rig 3.

[0031] Both sides of the workbench 4 are fixedly connected with side guard plates 401. Adjustable pressure plates 402 are installed at the front and rear ends of the side guard plates 401. The adjustable pressure plates 402 are used to assist in positioning. By adjusting the position of the adjustable pressure plates 402, the outside of the workpiece is clamped to assist in fixing.

[0032] The positioning frame base 5 is provided with a guide slide plate 507 on its outside, and a guide rail is provided on the upper surface of the worktable 4. The guide slide plate 507 is slidably connected to the worktable 4 through the guide rail. The positions of the two positioning frame bases 5 are adjusted according to the size of the workpiece. The positioning frame base 5 is slid by the guide slide plate 507 to keep the position of the positioning frame base 5 stable and adapt to different workpieces.

[0033] Specifically, by adjusting the position of the pressure plate 402, the workpiece is clamped externally to assist in fixing the work. The positions of the two positioning frame bases 5 are adjusted according to the size of the workpiece. The positioning frame bases 5 are slid by the guide slide plate 507 to keep the position of the positioning frame bases 5 stable and adapt to different workpieces. The processing work is carried out by adjusting the position of the lifting frame 2 and the moving drill 3.

[0034] Working principle: By adjusting the position of the adjusting pressure plate 402, the workpiece is clamped and fixed. The positions of the two positioning frame bases 5 are adjusted according to the size of the workpiece. The positioning frame bases 5 are slid by the guide slide plate 507 to keep the position of the positioning frame bases 5 stable, adapting to different workpieces. The two ends of the workpiece are inserted above the spring pressure plates 502 on both sides and fixed by the spring rod 504. After the position is stable, the power of the electromagnet column 503 is turned on. The electromagnet column 503 pushes the magnetic ring 508, causing the spring pressure plate 502 to squeeze the workpiece and lock it quickly. The structure is simple, the position is stable, and it is easy to disassemble and assemble for continuous work, improving work efficiency. The processing work is carried out by adjusting the position of the lifting frame 2 and the moving drill 3.
