[0002] A radial drilling machine is a hole-making machine characterized by a spindle that moves along the arm and rotates around the column, allowing for flexible adjustment of the machining position. This makes it suitable for multi-hole machining on large and heavy workpieces. In automotive manufacturing, radial drilling machines are primarily used for subsequent hole machining or finishing of large, low-precision stamping parts.

[0003] In the prior art, a fixture is usually set on top of the workbench. When processing automobile stamping parts, the automobile stamping parts are generally placed on the workbench of the radial drilling machine, and then fixed by a fixture composed of standardized angle irons, T-slot bolts, and adjustment pads.

[0038] A through hole 15 is provided in the middle of the top of the fixture mounting seat 6 , and the through hole 15 cooperates with the magnetic fixture 9 and the vacuum fixture 10 .

[0039] Working principle: The device is provided with a magnetic clamp 9 and a vacuum clamp 10. The magnetic clamp 9 is suitable for some steel structure automobile stamping parts (such as subframe connecting plates, suspension brackets), and the vacuum clamp 10 is suitable for some thin plate automobile stamping parts (such as inner and outer door panels, fenders, etc.). Select the appropriate clamp according to the type of automobile stamping parts. The magnetic clamp 9 and the vacuum clamp 10 replace the manual fixation method of automobile stamping parts in the traditional technology, shortening the time for replacing automobile stamping parts, which is beneficial to improving the production efficiency of radial drilling machines for automobile stamping parts. When the vacuum clamp 10 adsorbs and fixes the thin plate automobile stamping parts, the adsorption force is uniform, avoiding the problem of easy deformation of the clamping parts. By starting the cylinder 11, under the action of their corresponding connecting mechanism, telescopic mechanism and buffer mechanism, the magnetic clamp 9 or vacuum clamp 10 can be positioned Inside the through hole 15, the radial drilling machine can drill holes on automobile stamping parts. When drilling, the rocker arm 3 rotates around the column 2 and the processing device 4 moves horizontally along the rocker arm 3. The position of the processing device 4 is adjusted so that it can drill holes in different positions of automobile stamping parts. By setting up multiple adjustment slots 7 and multiple adjustment screws 8, the multiple adjustment screws 8 are loosened, and the clamp adjustment seat 5 can be moved on the top of the base 1, thereby adjusting the position of the clamp adjustment seat 5 and the clamp mounting seat 6, magnetic clamp 9, and vacuum clamp 10 on its top. The required position can be adjusted according to different automobile stamping parts. After the adjustment is completed, the position of the clamp adjustment seat 5 can be fixed again using multiple adjustment screws 8. With the setting of multiple adjustment slots 7, the user can fix the clamp adjustment seat 5 inside different adjustment slots 7 according to actual needs.

[0040] When it is necessary to use the magnetic clamp 9 to fix the automobile stamping parts, the following is the movement process of the magnetic clamp 9 and its bottom movable seat 13, connecting mechanism, telescopic mechanism, and buffer mechanism: in the initial state, the card plate 21 is inserted into the card slot 22, and the movable plate 12 is connected to the movable seat 13, so when the cylinder 11 pushes the movable plate 12 to move, the movable seat 13 can move synchronously with the movable plate 12, and the movable plate 12 and the movable seat 13 slide along the guide rod 38 to push the movable seat 13 to move toward the through hole 15. When the two extension plates 19 are respectively in contact with the two push plates 17, as the movable seat 13 continues to move, the two push plates 17 are respectively in contact with the two push plates 17. The two extension plates 19 generate a force, and the two extension plates 19 slide inside the two limit grooves 27 respectively, and drive the U-shaped bracket 16 to move to the side away from the movable plate 12. The two ends of the U-shaped bracket 16 move along the two guide rods 2 18 respectively. The U-shaped bracket 16 drives the two transmission rods 20 to move synchronously. The two transmission rods 20 slide inside their corresponding strip grooves 24 and act on the two side support plates 23 respectively. The two side support plates 23 are forced to drive the card plate 21 to move upward. When the two side support plates 23 move, they slide upward along the two guide rods 3 25 respectively, and the two springs 1 26 are stretched by the force. The card plate 21 gradually moves upward inside the card slot 22. When the two extension plates 19 move to the extreme ends of the two limit slots 27, the card plate 21 is completely separated from the card slot 22, thereby separating the movable plate 12 from the movable seat 13. At this time, the movable seat 13 and the magnetic clamp 9 are both located directly below the through hole 15. As the cylinder 11 continues to push, the movable plate 12 continues to move, while the movable seat 13 does not move synchronously with the movable plate 12. The movable plate 12 drives the two hook rods 32 to move synchronously. When the two hook rods 32 act on the two extension plates 2 33 respectively, the two extension plates 2 33 are forced to push the sliding plate 28 slides toward the side close to the movable plate 12, and the sliding plate 28 slides along the two guide rods 3 25. As the sliding plate 28 slides, the T-shaped slider 30 slides inside the T-shaped slot 29, so that the top plate 31 pushes up the clamp fixing seat 14 and the magnetic clamp 9. The clamp fixing seat 14 drives the four sliding brackets 36 at its bottom to slide upward along the four guide rods 4 34 respectively. The magnetic clamp 9 moves upward and extends into the through hole 15. The surface of the magnetic clamp 9 is flush with the surface of the clamp mounting seat 6. At this time, the automobile stamping parts can be fixed by the magnetic clamp 9, and then the automobile stamping parts can be drilled by the processing device 4.

[0041] When it is necessary to switch to the vacuum clamp 10, the cylinder 11 pushes the movable plate 12 to move in the opposite direction, so that the magnetic clamp 9 and the movable seat 13 at the bottom thereof are away from the through hole 15, and the vacuum clamp 10 and the movable seat 13 at the bottom thereof are close to the through hole 15. The movement process of the movable seat 13, the connecting mechanism, the telescopic mechanism, and the buffer mechanism at the bottom of the vacuum clamp 10 is the same as described above. The principles of the magnetic clamp 9 and the movable seat 13, the connecting mechanism, the telescopic mechanism, and the buffer mechanism at the bottom thereof in this process are as follows: the cylinder 11 drives the movable plate 12 to move toward the movable seat 13. First, since the movable seat 13 is not connected to the movable plate 12 at this time, the position of the movable seat 13 remains unchanged. The two hook rods 32 move synchronously with the movable plate 12, and the two extension plates 2 33 are not subject to the thrust of the two hook rods 32. Under the action of their own gravity, the magnetic clamp 9 and the clamp fixing seat 14 at the bottom thereof all move downward, and the four sliding brackets 36 respectively press the four springs 2 35 When the two side support plates 23 move downward, the U-shaped bracket 16 drives the two extension plates 19 to move to one side of the moving plate 12 for reset. At this time, the moving seat 13 and the magnetic clamp 9 move synchronously with the moving plate 12 to reset, thereby switching the vacuum clamp 10. The top of the magnetic clamp 9 or the vacuum clamp 10 is flush with the surface of the clamp mounting seat 6. The magnetic clamp 9 or the vacuum clamp 10 does not extend outside the clamp mounting seat 6, so as not to affect the placement of automobile stamping parts. Some larger stamping parts can also be placed on the surface of the clamp mounting seat 6, thereby improving the applicability of the radial drilling machine.
