Detailed implementation manners

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0019] Refer to Figures 1-3 , Figure 5 , Figure 8 and Figure 9 , a drilling device for metal sheet processing, including a processing table 1 with a plurality of support legs 2, and a placement groove 3 for placing metal sheets is opened on the processing table 1. A mounting plate 7 is fixedly installed on the processing table 1 through two fixing rods 6. A motor 8 is fixedly installed on the mounting plate 7. The driving end of the motor 8 is fixedly installed with a rotating shaft 9, and the rotating shaft 9 rotates through the mounting plate 7 and is fixedly installed with a drill bit 10; The following points are worthy of attention: 1. The number of support legs 2 is at least three, and four are shown in the figure. When specifically set, they should be evenly spaced on the processing table 1; A suction cup can be arranged on the lower surface of the support leg 2, so that the whole device is more stable when placed.

[0020] 2. Rubber pads are fixedly arranged on the inner walls on both sides of the placement groove 3. The elasticity of the rubber pads can be used to prevent the metal sheet from directly contacting the inner walls on both sides of the placement groove 3 when placed; This layer of rubber pad can also be arranged on the bottom wall of the placement groove 3.

[0021] 3. A motor cover can be fixedly arranged on the mounting plate 7, and the motor 8 is located inside the motor cover, which plays a certain isolation and protection effect on the motor 8, and can also reduce the noise generated by the operation of the motor 8 to a certain extent.

[0022] Refer to Figure 1 , Figure 3 , Figure 4 ,Figure 6 , Figure 7 , there are two reciprocating lead screws 11 rotatably installed between the processing table 1 and the mounting plate 7, and a linkage structure is installed between the rotating shaft 9 and the two reciprocating lead screws 11. A cover body 14 is fixedly installed on the lower surface of the mounting plate 7, and the linkage structure is located inside the cover body 14. Lifting blocks 16 are installed on both reciprocating lead screws 11 through ball nuts 15. Two cross bars 17 are fixedly installed on each of the two lifting blocks 16. One end of each cross bar 17 is fixedly installed with a screw 18. A plurality of screws 18 are installed with a lifting plate 21 through a support structure. And a lifting groove 4 matching with the lifting plate 21 is opened on the bottom wall of the placing groove 3. A through hole 22 matching with the drill bit 10 is opened at the middle position of the lifting plate 21; The following points are worthy of attention: 1. The linkage structure is composed of a transmission wheel 12 and a transmission belt 13. A transmission wheel 12 is fixedly installed on the rotating shaft 9 and the two reciprocating lead screws 11, and a transmission belt 13 is sleeved on the plurality of transmission wheels 12 together; The setting of the linkage structure enables the rotating shaft 9 to drive the two surrounding reciprocating lead screws 11 to rotate together when rotating; At the same time, the setting of the cover body 14 plays a role in shielding and protecting the transmission wheel 12 and the transmission belt 13, effectively reducing the influence of external factors on this part.

[0023] 2. The support structure is composed of a cross bar 19, a circular plate 20 and a connecting groove 5. Four connecting grooves 5 are opened on the processing table 1, and the connecting grooves 5 are connected with the placing groove 3 and the lifting groove 4. The lower end of the screw 18 is located in the connecting groove 5 and fixedly installed with a cross bar 19. The two corresponding cross bars 19 are fixedly installed with a circular plate 20 together, and the circular plate 20 is symmetrically fixed on both sides of the lower surface of the lifting plate 21; The setting of the support structure is used to drive the lifting plate 21 to move together with the vertical movement of the screw 18 in the vertical direction (height adjustment in the vertical direction, the screw 18 itself will not rotate, but only move in the vertical direction along with the cross bar 17).

[0024] 3. A rubber pad can also be fixedly arranged on the upper surface of the lifting plate 21 to avoid the direct contact between the lifting plate 21 and the scripture board by using the elasticity of the rubber pad.

[0025] Refer to Figure 1 and Figures 3-9 , a gathering cover 26 is installed on the rotating shaft 9 through a vertical sliding structure. A magnetic chip suction structure is installed on the gathering cover 26. A magnetic repulsion structure is installed between the cover body 14 and the gathering cover 26; Among them, a plate pressing structure is installed on the two screws 18; The following points are worthy of attention: 1. The vertical sliding structure includes a strip-shaped chute 24 and a slider 25. A plurality of strip-shaped chutes 24 are equidistantly formed on the rotating shaft 9. A slider 25 is slidably installed in each strip-shaped chute 24, and the slider 25 is fixedly arranged on the upper inner wall of the converging cover 26; The setting of the vertical sliding structure enables the converging cover 26 to rotate along with the rotation of the rotating shaft 9. At the same time, the converging cover 26 can also move in the vertical direction relative to the rotating shaft 9, meeting the usage requirements.

[0026] 2. The magnetic chip attracting structure is composed of a threaded groove, an annular body 27, and magnetic rods 28. A threaded groove is formed on the lower inner wall of the converging cover 26. The annular body 27 is threadedly installed in the threaded groove, and a plurality of magnetic rods 28 are fixedly installed in the annular body 27 at equal intervals; The setting of the magnetic chip attracting structure is used to adsorb and remove more metal chips generated during the drilling process.

[0027] 3. The magnetic force repelling structure is composed of a magnetic ring 30 and magnetic blocks 31. The magnetic ring 30 is fixedly installed on the lower surface of the cover body 14. A plurality of magnetic blocks 31 are fixedly installed on the upper end surface of the converging cover 26 at equal intervals, and the magnetic sides of the magnetic ring 30 and the magnetic blocks 31 close to each other have the same magnetic property; The setting of the magnetic force repelling structure enables the converging cover 26 to always be under a vertical acting force, so that the lower end of the converging cover 26 can better contact the upper surface of the metal plate.

[0028] 4. The plate pressing structure is composed of a limit slide bar 23, a disc body 32, a connecting rod 33, a pressing block 34, and a limit slide hole. A disc body 32 is threadedly installed on the two screw rods 18. The connecting rod 33 is rotatably installed on the disc body 32, and the lower end of the connecting rod 33 is fixedly installed with a pressing block 34. Two limit sliders are formed on the two connecting rods 33, and a plurality of limit slide bars 23 matched with the limit slide holes are fixedly installed on the processing table 1; The setting of the plate pressing structure is used to apply a vertical pressing force to the plate after it is placed. At this time, the lower surface of the metal plate contacts the upper surface of the lifting plate 21, thereby avoiding movement or shaking during drilling and improving the accuracy during drilling.

[0029] Further explanation, the above fixed connection, unless otherwise clearly specified and limited, should be understood in a broad sense. For example, it can be welding, gluing, or integrally formed setting, etc., which are common means well-known to those skilled in the art.

[0030] In the present invention, the metal plate to be drilled is placed on the placement groove 3 so that the position to be drilled corresponds to the through hole 22. Then, a rotational force is applied to the two discs 32 by hand. At this time, the discs 32 will rotate vertically relative to the screw rod 18. The vertical movement of the discs 32 drives the connecting rod 33 to move vertically (under the limiting action of the limiting slide rod 23, the connecting rod 33 will not rotate with the discs 32 but only move vertically with them). The vertical movement of the connecting rod 33 drives the pressing block 34 to move vertically, thereby pressing the metal plate (in the initial state, the pressing block 34 is at the highest position. Rotate the disc 32 to make the pressing block 34 move downward). Then, start the motor 8. The motor 8 works to directly drive the drill bit 10 to rotate. The rotation of the rotating shaft 9 drives the two reciprocating lead screws 11 to rotate through the cooperation of the transmission wheels 12 and the transmission belt 13. The rotation of the two reciprocating lead screws 11 drives the two lifting blocks 16 to move reciprocally in the vertical direction through the ball nuts 15 (during the upward movement to the highest position, drilling is completed, and during the downward movement, it is for reset). The upward movement of the lifting block 16 drives the screw rod 18 to move upward together through the first cross bar 17. The upward movement of the screw rod 18 drives the metal plate to move upward under the cooperation of the second cross bar 19 and the circular plate 20. During this process, the pressing block 34 also moves upward together to press the metal plate. During the upward movement, the metal plate will contact the drill bit 10, thereby completing the required drilling. The converging cover 26 will first contact the metal plate, which plays a role in intercepting and collecting the metal chips generated during the drilling process. Moreover, the converging cover 26 can move to a certain extent vertically relative to the rotating shaft 9, so as not to affect the drilling operation of the drill bit 10 on the metal plate.

[0031] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
