Description

Technical Field

[0001] This invention relates to the field of drilling equipment technology, specifically to a mechanical metal plate drilling device. Background Technology

[0002] Metal sheets are made of metal materials, such as aluminum and aluminum alloys, steel, stainless steel, and copper.

[0003] Metal sheets need to be perforated during the production process, so drilling machines are used. Drilling machines are a general term for machinery and equipment that use tools that are harder and sharper than the target object to leave cylindrical holes or openings in the target object through rotary cutting or rotary extrusion.

[0004] Existing drilling devices only achieve simple cooling during the drilling process, but do not take into account the debris left on the surface of the drill bit after the work is completed. This requires manual cleaning later, which is quite troublesome. If it is forgotten to be cleaned later, it will affect subsequent drilling work.

[0005] Therefore, it is necessary to design a highly practical drilling device for metal plates in machinery. Summary of the Invention

[0006] The purpose of this invention is to provide a drilling device for metal plates for machinery, so as to solve the problems mentioned in the background art.

[0010] The working component is positioned between the workbench and the U-shaped frame;

[0011] The working component includes a drilling section installed on the lower surface of the U-shaped frame, the drilling section being connected to a cooling section, and the cooling section being connected to a cleaning section.

[0012] According to the above technical solution, support frames are fixedly installed at the bottom of both ends of the workbench, and a bottom frame is fixedly installed at the bottom of the support frames.

[0013] The above technical solution provides stable support for the entire device through the support frame, while the bottom frame installed at the bottom of the support frame further enhances its stability.

[0014] According to the above technical solution, a cylinder is fixedly installed at the slot of the workbench, and a clamping plate is fixedly installed at one end of the cylinder.

[0015] By adopting the above technical solution, the position of the clamping plate can be adjusted by the set cylinder, thereby enabling the clamping of metal plates of different sizes.

[0028] The number of the bent rods and L-shaped tubes is two, and the two bent rods and L-shaped tubes are symmetrically distributed on the left and right sides with the center line of the front of the auxiliary plate as the axis of symmetry.

[0029] By adopting the above technical solution, the drill bit can be cooled after drilling is completed, thus preventing the drill bit from being in a high-temperature state after operation, which would affect the service life of the drill bit in the later stage.

[0030] According to the above technical solution, the cleaning unit includes:

[0031] The cover is slidably fitted onto the outside of the drill bit;

[0032] The bottom surface of the cover is hollowed out, the outer wall of the cover has a rectangular opening, the inner wall of the rectangular opening has a rectangular groove, and an installation plate is fixedly installed on the outside of the cover. The two ends of the installation plate are fixedly installed on the inner side of the U-shaped frame, and the installation plate is movably sleeved on the outer wall of the bent rod and L-shaped tube.

[0033] A movable block slides through the rectangular opening and extends into the enclosure, with one end of the movable block protruding outside the enclosure.

[0034] The movable block has a semi-circular shape at the end closest to the drill bit, and bristles are installed at this semi-circular structure. The movable block has a quarter-circular shape at the end furthest from the drill bit.

[0038] A collection hood has an opening on its top surface, which is fitted onto the outside of the drill bit, and the outer wall of the collection hood is fitted onto the inner wall of the hood body.

[0039] By adopting the above technical solution, it is possible to process the chips from the drill bit after the work is completed without manual processing, which is quite convenient.

[0040] According to the above technical solution, the inner diameter of the circular opening on the top surface of the cover is slightly larger than the outer diameter of the drill bit.

[0041] By adopting the above technical solution, friction between the cover and the drill bit can be avoided, which would affect its use.

[0042] According to the above technical solution, there are multiple obstructions, and each obstruction is made of rubber.

[0043] By adopting the above technical solution, the auxiliary rod can be effectively squeezed and pass through the obstruction.

[0044] According to the above technical solution, the inner diameter of the opening on the top surface of the collection cover is slightly larger than the outer diameter of the drill bit, the outer wall of the collection cover is provided with an outer annular groove, and the outer edge of the upper end of the collection cover is rounded.

[0045] By adopting the above technical solution, friction between the collection cover and the drill bit can be avoided, which would affect its use. At the same time, the outer annular groove and the rounded corners are designed so that the debris can fall and be collected and processed in a concentrated manner.

[0046] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0047] 1. The present invention provides a metal plate drilling device for machinery. The position of the drill bit can be adjusted by a hydraulic cylinder, thereby adapting to metal plates of different thicknesses. Finally, the drilling operation is achieved by the drill bit under the action of a motor.

[0048] 2. The present invention provides a metal plate drilling device for machinery. By means of a bent rod and a piston, the airflow inside the L-shaped tube can be brought into the cover body under the action of a hydraulic cylinder, thereby achieving the purpose of cooling the drill bit.

[0049] 3. The present invention provides a metal plate drilling device for machinery. Under the action of a hydraulic cylinder, a bent rod, and a blocking body, an auxiliary rod can squeeze a movable block. Then, under the action of a sliding rod and a spring, the brush bristles can vibrate, increasing the cleaning force of the brush bristles on the drill bit. At the same time, the dust on the brush bristles can fall onto the collection cover for easy centralized treatment.

[0050] 4. The present invention provides a metal plate drilling device for machinery. The airflow inside the L-shaped tube is blown into the cover body, which can increase the fluidity of the bristles and can also blow towards the drill bit, thus assisting in the dust removal function.

[0061] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1

[0062] A preferred embodiment of the metal plate drilling device for machinery provided by the present invention is as follows: Figures 1 to 8 As shown:

[0063] A drilling device for metal plates for machinery, comprising:

[0064] Workbench 1, the top of which has a slotted design;

[0065] Among them, support frames 2 are fixedly installed at the bottom of both ends of the workbench 1, and bottom frames 3 are fixedly installed at the bottom of the support frames 2. The support frames 2 can provide stable support for the entire device, and the bottom frames 3 installed at the bottom of the support frames 2 assist in the stability of the support frames 2. A cylinder 4 is fixedly installed at the slot of the workbench 1, and a clamping plate 5 is fixedly installed at one end of the cylinder 4. The position of the clamping plate 5 can be adjusted by the cylinder 4, thereby enabling the clamping of metal plates of different sizes.

[0066] U-shaped frame 6 is fixedly installed on the top surface of workbench 1;

[0067] The working component 7 is located between the workbench 1 and the U-shaped frame 6;

[0068] The working component 7 includes a drilling section 71 installed on the lower surface of the U-shaped frame 6, a cooling section 72 connected to the drilling section 71, and a cleaning section 73 connected to the cooling section 72.

[0069] The drilled portion 71 includes:

[0070] Hydraulic cylinder 711 is fixedly installed on the lower surface of U-shaped frame 6;

[0071] The auxiliary plate 712 is fixedly installed at the bottom end of the hydraulic cylinder 711;

[0072] Motor 713 is mounted on the bottom of auxiliary plate 712;

[0073] Drill bit 714 is fixedly installed at the output end of motor 713.

[0074] In the specific implementation process, the metal plate to be drilled is first placed in the slot on the top surface of the workbench 1. Then, the clamping plate 5 is clamped by starting the cylinder 4. After clamping, the hydraulic cylinder 711 is started to move the motor 713 installed at the bottom of the auxiliary plate 712 downward. When the drill bit 714 installed at the output end of the motor 713 contacts the metal plate, the motor 713 can be started to work and drive the drill bit 714 to work, thus completing the drilling work.

[0075] In this embodiment, there are two hydraulic cylinders 711. The two hydraulic cylinders 711 are symmetrically distributed on both sides with the center line of the front of the U-shaped frame 6 as the axis of symmetry. By setting two hydraulic cylinders 711 and symmetrically setting them, the position of the rest of the structure of the drilling part 71 can be stably adjusted. Example 2

[0076] Based on Example 1, a preferred embodiment of the mechanical metal plate drilling device provided by the present invention is as follows: Figures 1 to 8 As shown:

[0077] Cooling section 72 includes:

[0078] The bent rod 721 is fixedly installed at the bottom of the auxiliary plate 712;

[0079] The L-shaped tube 722 is slidably sleeved on the outside of the bent rod 721, and the L-shaped tube 722 is connected to the cleaning part 73.

[0080] The inner wall of the L-shaped tube 722 is provided with an inner annular groove, and a piston 723 is slidably arranged on the inner wall of the inner annular groove. The bottom surface of the piston 723 is fixedly installed with the end of the bent rod 721 away from the auxiliary plate 712.

[0081] Among them, there are two bent rods 721 and two L-shaped tubes 722, and the two bent rods 721 and L-shaped tubes 722 are symmetrically distributed on the left and right sides with the center line of the front of the auxiliary plate 712 as the axis of symmetry.

[0082] In the specific implementation process, after the drilling work is completed, the hydraulic cylinder 711 drives the auxiliary plate 712, motor 713 and drill bit 714 to move upward. During the upward movement of the auxiliary plate 712, the bent rod 721 can be moved upward. The upward movement of the bent rod 721 can move the piston 723 installed at one end of the bent rod 721. During the movement of the piston 723, an airflow is generated, which blows towards the drill bit 714 to achieve a local cooling effect. Example 3

[0083] Based on Embodiments 1 and 2, a preferred embodiment of the mechanical metal plate drilling device provided by the present invention is as follows: Figures 1 to 8 As shown:

[0084] Cleaning Department 73 includes:

[0085] The cover 731 is slidably sleeved on the outside of the drill bit 714;

[0086] The bottom surface of the cover 731 is hollowed out, and a rectangular opening 9 is provided on the outer wall of the cover 731. A rectangular groove 10 is provided on the inner wall of the rectangular opening 9. An installation plate 8 is fixedly installed on the outside of the cover 731. The two ends of the installation plate 8 are fixedly installed on the inner side of the U-shaped frame 6, and the installation plate 8 is movably sleeved on the outer wall of the bent rod 721 and the L-shaped tube 722.

[0087] Movable block 732 slides through rectangular opening 9 and extends into cover 731, with one end of movable block 732 protruding outside cover 731;

[0088] Among them, the end of the movable block 732 near the drill bit 714 is set in a semi-circular shape, and bristles 733 are installed in the semi-circular structure; the end of the movable block 732 away from the drill bit 714 is set in a quarter-circular shape.

[0089] The obstruction 734 is fixedly installed on the outer surface of the movable block 732;

[0090] An auxiliary rod 735 is fixedly installed on the surface of the bent rod 721, and the end of the auxiliary rod 735 away from the bent rod 721 is slidably disposed with respect to the surface of the movable block 732;

[0091] A slide bar 737 is fixedly installed on the surface of the movable block 732. The slide bar 737 is slidably disposed in the rectangular groove 10, and a spring 738 is fixedly installed on the surface of the slide bar 737. The end of the spring 738 away from the slide bar 737 is fixedly installed to the inner wall of the rectangular groove 10.

[0092] The collection cover 736 has an opening on its top surface, which is fitted onto the outside of the drill bit 714. The outer wall of the collection cover 736 is fitted onto the inner wall of the cover body 731.

[0093] In the specific implementation process, as the drill bit 714 moves upward, it will come into contact with and rub against the brush bristles 733, which can play a cleaning role. At the same time, with the cooperation of the curved rod 721 and the obstruction body 734, the movable block 732 can be squeezed. Then, with the cooperation of the slide rod 737 and the spring 738, the movable block 732 can be vibrated. This not only enables large-amplitude cleaning of the drill bit 714, but also makes the brush bristles 733 vibrate, so that the dust falls smoothly into the collection cover 736. When centralized cleaning is needed, simply pull the collection cover 736 downward with force.

[0094] In this embodiment, the inner diameter of the circular opening on the top surface of the cover 731 is slightly larger than the outer diameter of the drill bit 714. This avoids friction between the cover 731 and the drill bit 714, which would affect its use.

[0095] Furthermore, there are multiple obstructions 734, and each obstruction 734 is made of rubber, so that the auxiliary rod 735 can be squeezed well and pass through the obstruction 734.

[0096] Furthermore, the inner diameter of the opening on the top surface of the collection cover 736 is slightly larger than the outer diameter of the drill bit 714. The outer wall of the collection cover 736 has an outer annular groove, and the outer edge of the upper end of the collection cover 736 has rounded corners. By setting the inner diameter of the opening of the collection cover 736 to be larger than the outer diameter of the drill bit 714, friction between the collection cover 736 and the drill bit 714 can be avoided, which would affect its use. At the same time, the outer annular groove on the outside of the collection cover 736 and the rounded corners at the upper end of the collection cover 736 are for the purpose of collecting and processing debris.
