DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] The terms "upper", "lower", "left", "right", "middle" and "one" used in the present invention are only for the convenience of description and are not intended to limit the scope of application of the present invention. Changes or adjustments to their relative relationships shall be deemed to be within the scope of application of the present invention without substantially changing the technical content.

[0022] Reference Figures 1-4 A drilling and grinding device for precision machinery manufacturing used in aerospace, including a table body 1, an L-shaped mounting plate is fixedly installed on the upper surface of the table body 1, a lifting cylinder 2 is fixedly installed on the upper surface of the mounting plate, the driving shaft of the lifting cylinder 2 passes through the mounting plate and is fixedly installed with a driving motor 3, a drill rod 4 is fixedly installed at the bottom end of the output shaft of the driving motor 3, a mounting plate 5 is fixedly sleeved on the output shaft of the driving motor 3, and a grinding wheel 7 is provided under the mounting plate 5.

[0023] The lower surface of the mounting plate 5 is symmetrically fixed with an insertion rod 6, and the upper surface of the grinding wheel 7 is symmetrically and vertically fixed with a hollow rod 8. The two hollow rods 8 are respectively slidably sleeved on the two insertion rods 6. A through hole 9 for the drill rod 4 to pass through is opened at the center of the surface of the grinding wheel 7, and the grinding wheel 7 is locked by a locking assembly.

[0024] The lifting cylinder 2 can move downward with the driving motor 3, the grinding wheel 7 and the drill rod 4, and the driving motor 3 can rotate with the grinding wheel 7 and the drill rod 4. When the workpiece needs to be polished, it is only necessary to release the lock of the grinding wheel 7 by the locking assembly, and then control the grinding wheel 7 to move downward, so that the grinding wheel 7 moves to the bottom of the drill rod 4, and then lock the grinding wheel 7. At this time, when the driving motor 3 rotates with the drill rod 4 and the grinding wheel 7, the drill rod 4 does not contact the workpiece, and the grinding wheel 7 can polish the workpiece.

[0025] When it is necessary to drill a hole in the workpiece, it is only necessary to release the lock on the grinding wheel 7 by the locking assembly, and then control the grinding wheel 7 to move upward, so that the grinding wheel 7 moves to above the drill rod 4, and then lock the grinding wheel 7. At this time, when the drive motor 3 rotates with the drill rod 4 and the grinding wheel 7, the grinding wheel 7 does not contact the workpiece, and the drill rod 4 can grind the workpiece.

[0026] By adjusting the vertical movement of the grinding wheel 7 and changing the height position relationship between the grinding wheel 7 and the drill rod 4, the grinding and drilling work can be achieved with only one set of electric drive device.

[0027] The locking assembly includes an L-shaped support plate 10, a sliding rod 11 and a trapezoidal locking block 12 fixedly installed at one end of the sliding rod 11. The two support plates 10 are respectively fixedly sleeved on the two hollow rods 8. A through hole is opened on the surface of the support plate 10, and the sliding rod 11 is slidably inserted in the through hole. The end of the sliding rod 11 away from the locking block 12 is fixedly installed with a mounting block, and the mounting block is connected to the support plate 10 through a telescopic component. The telescopic component includes a telescopic spring 16 sleeved on the sliding rod 11, and the two ends of the telescopic spring 16 are respectively fixedly connected to the mounting block and the support plate 10. An L-shaped vertical plate 13 is symmetrically and vertically fixedly installed on the lower surface of the mounting plate 5. A locking hole 14 for inserting the locking block 12 is opened on the surface of the vertical plate 13, and a limiting hole 15 is symmetrically opened on the upper surface of the mounting plate 5. The upper surfaces of the two locking blocks 12 correspond to the positions of the lower surface of the mounting plate 5, and do not correspond to the positions of the two limiting holes 15.

[0028] When the grinding wheel 7 is controlled to move downward, the two sliding rods 11 are controlled to move closer to each other until the grinding wheel 7 moves down to the bottom, that is, when the grinding wheel 7 is located below the drill rod 4, the two locking blocks 12 will respectively correspond to the positions of the two locking openings 14, and then the two sliding rods 11 are released. The two sliding rods 11 will quickly move and reset with the two locking blocks 12 under the elastic potential energy of the two telescopic springs 16, and the two locking blocks 12 will be respectively inserted into the two locking openings 14, thereby completing the locking of the grinding wheel 7.

[0029] When the lock needs to be released, the two sliding rods 11 are simply moved closer to each other to move the two locking blocks 12 out of the two locking openings 14 respectively.

[0030] After the grinding wheel 7 is unlocked, the grinding wheel 7 can be controlled to move upward until the grinding wheel 7 moves to the highest point, that is, the grinding wheel 7 is located above the drill rod 4. At this time, since the telescopic spring 16 is in a stretched state, the position of the locking block 12 will change, and the upper surfaces of the two locking blocks 12 will correspond to the positions of the two limiting openings 15 respectively. The top ends of the two support plates 10, the two sliding rods 11 and the two locking blocks 12 will pass through the two limiting openings 15 respectively. Then, the two sliding rods 11 are released at this time, and the two sliding rods 11 will quickly move and reset under the elastic potential energy of the telescopic spring 16. At this time, the lower surfaces of the two locking blocks 12 will both be against the upper surface of the mounting plate 5, thereby locking the grinding wheel 7 and limiting its downward movement.

[0031] When the lock needs to be released, it is only necessary to control the two slide bars 11 to move closer to each other so that the lower surface of the locking block 12 no longer abuts against the upper surface of the mounting plate 5 .

[0032] The vertical plate 13 is provided with an inclined wall 17 , and the inclined wall 17 is parallel to the inclined surface of the locking block 12 .

[0033] When the lock of the grinding wheel 7 at the top is released and the grinding wheel 7 is controlled to move downward, there is no need to control the two slide bars 11 to approach each other. It is only necessary to control the grinding wheel 7 to move downward. The inclined surfaces of the two locking blocks 12 will slide in contact with the inclined walls 17 of the two vertical plates 13 respectively. Under the action of the inclined surfaces, the two slide bars 11 will approach each other, and the telescopic spring 16 will stretch until the grinding wheel 7 moves to the bottom. At this time, the two locking blocks 12 will correspond to the positions of the two locking openings 14 respectively, and the pressing force exerted by the vertical plate 13 on the locking block 12 disappears. The locking block 12 and the slide bar 11 will quickly move and reset under the elastic potential energy of the telescopic spring 16, and be inserted into the locking opening 14 corresponding to their own positions.

[0034] The surfaces of the two support plates 10 are provided with a pressing component, which is used to control the two sliding rods 11 to move away from each other. The pressing component includes two sliders 18, a movable plate 19 fixedly connected to the two sliders 18, and two pressing rods 20 symmetrically fixedly installed on the surface of the movable plate 19. A fixed block is fixedly sleeved on the sliding rod 11, and an inclined plate 21 is fixedly installed on the bottom end of the fixed block. A sliding groove is vertically opened on the surface of the support plate 10, and the two sliders 18 are respectively slidably arranged in the two sliding grooves, and the two pressing rods 20 are respectively pressed against the inclined surfaces of the two inclined plates 21.

[0035] When it is necessary to control the two slide bars 11 to move closer to each other, it is only necessary to control the movable plate 19 to move the two push rods 20 upward, and the two push rods 20 will respectively slide into contact with the two inclined plates 21. Under the action of the inclined surface pressure, the two slide bars 11 will move laterally closer to each other. There is no need to control the movement of the two slide bars 11 one by one, which is convenient and quick.

[0036] In the present invention, the lifting cylinder 2 can move down with the driving motor 3, the grinding wheel 7 and the drill rod 4, and the driving motor 3 can rotate with the grinding wheel 7 and the drill rod 4. When it is necessary to grind the workpiece, it is only necessary to release the lock of the grinding wheel 7 from the locking assembly, and then control the grinding wheel 7 to move down, so that the grinding wheel 7 moves to the bottom of the drill rod 4, and then lock the grinding wheel 7. At this time, when the driving motor 3 rotates with the drill rod 4 and the grinding wheel 7, the drill rod 4 does not contact the workpiece, and the grinding wheel 7 can grind the workpiece. When it is necessary to drill a hole in the workpiece, it is only necessary to release the lock of the grinding wheel 7 on the locking assembly, and then control the grinding wheel 7 to move upward, so that the grinding wheel 7 moves to above the drill rod 4, and then lock the grinding wheel 7. At this time, when the drive motor 3 rotates with the drill rod 4 and the grinding wheel 7, the grinding wheel 7 does not contact the workpiece, and the drill rod 4 can grind the workpiece. By adjusting the vertical movement of the grinding wheel 7 and changing the height position relationship between the grinding wheel 7 and the drill rod 4, the grinding and drilling work can be achieved with only one set of electric drive device.

[0037] In the present invention, unless otherwise clearly specified or limited, the terms “installed”, “connected”, “connected”, “fixed” and the like should be understood in a broad sense.

[0038] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
