Description

Technical Field

[0001] This invention relates to the field of casing drilling technology, and more specifically to a drilling device for the production of chainsaw casings. Background Technology

[0002] A chainsaw is a handheld cutting tool powered by a two-stroke gasoline engine. Its core components include the engine, saw chain, guide plate, and chainsaw braking system. A chainsaw is a handheld power tool that uses a gasoline engine to cut wood by moving the L-shaped blades on the saw chain laterally. It is mainly used in logging, garden trimming, and fire rescue and disaster relief.

[0003] As a key power tool in forestry, garden maintenance and emergency rescue, the outer shell of the chainsaw is usually made of lightweight and high-strength aluminum alloy or magnesium alloy die casting to meet the requirements of portability and durability. After the chainsaw outer shell is integrally die-cast, it needs to be drilled to connect with the other electronic components inside to complete the overall production process of the chainsaw.

[0004] When drilling holes in the casing of a chainsaw, it needs to be clamped and fixed. Before drilling, the chainsaw is already integrated and pressed for support, so its casing shape is quite heavy. Therefore, current clamping equipment cannot adapt to the internal shape of chainsaws with complex shapes. If too much force is applied, it will damage the casing of the chainsaw. In addition, different chainsaw models have different external dimensions, and current clamping devices cannot automatically adjust according to the model of the chainsaw, making clamping inconvenient.

[0005] Nowadays, clamping is a rather cumbersome process, and when drilling holes in the chainsaw casing, the cutting tool gets very hot during multiple drilling operations, which can easily lead to tool damage. Summary of the Invention

[0006] In order to overcome the above-mentioned defects of the prior art, embodiments of the present invention provide a drilling device for the production of chainsaw casings to solve the technical problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a drilling device for producing chainsaw casings, comprising a drilling machine tool, a drilling assembly on the side of the drilling machine tool, a drilling punch fixedly connected to the side of the drilling assembly near the side of the drilling machine tool, a placement table fixedly connected to the center of the top of the drilling machine tool, the drilling punch located above the placement table, an output mechanism movably connected inside the drilling machine tool, clamping mechanisms fixedly connected to both sides of the top of the output mechanism, two clamping mechanisms located on both sides of the placement table, an exhaust pipe on the side of the placement table away from the drilling assembly, a smoke exhaust mechanism fixedly connected to the bottom end of the exhaust pipe, and when the two clamping mechanisms move closer to each other, they flexibly fix the chainsaw casing above the placement table, and the clamping angle of the clamping mechanism is adapted to the size of the chainsaw casing.

[0008] In a preferred embodiment, the clamping mechanism includes a fixed plate for support and fixation, a support plate is fixedly connected to the middle of the top of the fixed plate, fixed shafts are fixedly connected to both sides of the top of the fixed plate, clamping plates are movably connected to the sides of both fixed shafts, a threaded rod is movably connected inside the support plate, and an adjusting wheel is fixedly connected to the side of the threaded rod, the adjusting wheel being located on the side of the support plate away from the threaded rod.

[0009] In a preferred embodiment, a threaded sleeve is threadedly connected to the side of the threaded rod away from the adjusting wheel, a top plate is fixedly connected to the side of the threaded sleeve away from the adjusting wheel, an extension plate is fixedly connected to both the top and bottom ends of the top plate, and a second connecting shaft is fixedly connected to both sides of the extension plate that are close to each other.

[0010] In a preferred embodiment, connecting plates are movably sleeved on the sides of both second couplings, and a first coupling is movably connected to the interior of the connecting plates away from the second couplings. Locking plates are fixedly connected to the top and bottom of the first couplings, and the sides of the locking plates away from the first couplings are fixedly connected to the sides of the clamping plates.

[0011] In a preferred embodiment, a flexible inner liner is fixedly connected to the sides of the two clamping plates away from the fixed axis. The two ends of the flexible inner liner are fixedly connected to the clamping plates respectively, and the middle part of the flexible inner liner is fixedly connected to the side of the top plate away from the threaded sleeve.

[0012] In a preferred embodiment, limiting posts are fixedly connected to the adjacent sides of the two clamping plates. The flexible inner liner is located between the clamping plates and the limiting posts, and the two sides and the middle part of the flexible inner liner are fixedly connected to the clamping plates and the top plate, respectively. The contact portion between the flexible inner liner and the limiting posts moves within the limiting posts.

[0013] In a preferred embodiment, the output mechanism includes an output motor that provides power. A bidirectional screw is fixedly connected to the side of the output motor. The two sides of the bidirectional screw are provided with threaded grooves that are mirror-symmetrical about the central plane of the drilling machine. A movable plate is threadedly connected to the side of each threaded groove of the bidirectional screw. The top end of the movable plate is fixedly connected to the bottom end of the clamping mechanism.

[0014] In a preferred embodiment, a limiting plate is fixedly connected to the bottom end of the movable plate, and limiting rods are movably connected to both sides inside the limiting plate. The two ends of the limiting rods are fixedly connected to the interior of the drilling machine tool, and the bidirectional screw passes through the placement table and is movably connected to the placement table.

[0015] In a preferred embodiment, the smoke exhaust mechanism includes an air intake cylinder fixedly connected to an exhaust pipe. The air intake cylinder is located at the bottom end of the exhaust pipe and is connected to the exhaust pipe. A rotating motor is provided on the side of the air intake cylinder near the drilling machine tool. A rotating shaft is fixedly connected to the side of the rotating motor, and a blade assembly is fixedly connected to the side of the rotating shaft.

[0016] In a preferred embodiment, the blade assembly is located inside the intake cylinder, and there are two blade assemblies, both of which are located on the side of the exhaust pipe away from the rotating motor. A sealing plate is fixedly connected to the side of the rotating motor.

[0017] The technical effects and advantages of this invention are as follows:

[0018] 1. When the present invention clamps the chainsaw shell, the output motor starts and drives the bidirectional screw to rotate. When the bidirectional screw rotates, the two moving plates move inward synchronously. When the moving plates move inward synchronously, they drive the two clamping mechanisms to move inward as a whole. When the clamping mechanism moves and clamps the chainsaw shell, the flexible inner lining plate contacts the chainsaw shell, achieving a flexible clamping effect. It can clamp at multiple points, ensuring that the clamping is strong enough while allowing for quick clamping and fixing before drilling.

[0019] 2. When clamping chainsaw shells of different sizes, the present invention rotates the adjusting wheel, which drives the threaded rod to rotate. When the threaded rod rotates, the threaded sleeve drives the top plate to move. When the top plate moves away from the support plate, the clamping plate moves inward through the connecting plate. When the top plate moves closer to the support plate, the clamping plate moves outward, thereby adjusting the clamping angle to adapt to different chainsaw shells. When the clamping plate changes angle, the flexible inner lining plate remains in contact with the clamping plate under the restriction of the limiting post, thus ensuring the effect of flexible clamping.

[0020] 3. When the punch of the present invention punches a hole in the casing of a chainsaw, the rotating motor starts and drives the rotating shaft to rotate. When the rotating shaft rotates, it drives the two blade groups on the side to rotate. When the blade groups rotate, they absorb gas from the outside through the air suction cylinder. The exhaust pipe blows the gas in the air suction cylinder to the contact surface between the punch and the casing of the chainsaw. At this time, the punch and the casing of the chainsaw will be cooled down quickly to ensure that they can be used for a long time. Attached Figure Description

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The drilling device for producing chainsaw casings involved in the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Reference Figure 1 , Figure 2 as well as Figure 3 This invention provides a drilling device for producing chainsaw casings, including a drilling machine tool 1, a drilling assembly 2 on the side of the drilling machine tool 1, a drilling punch 3 fixedly connected to the side of the drilling assembly 2 near the side of the drilling machine tool 1, a placement table 8 fixedly connected to the middle of the top of the drilling machine tool 1, the drilling punch 3 located above the placement table 8, an output mechanism 5 movably connected inside the drilling machine tool 1, clamping mechanisms 6 fixedly connected to both sides of the top of the output mechanism 5, the two clamping mechanisms 6 located on both sides of the placement table 8, an exhaust pipe 4 provided on the side of the placement table 8 away from the drilling assembly 2, and a smoke exhaust mechanism 7 fixedly connected to the bottom end of the exhaust pipe 4. When the two clamping mechanisms 6 move closer to each other, they flexibly fix the chainsaw casing above the placement table 8, and the clamping angle of the clamping mechanism 6 is adapted to the size of the chainsaw casing.

[0032] In this embodiment, when the chainsaw casing is clamped, the two clamping mechanisms 6 move inward as a whole. At this time, the two clamping mechanisms 6 clamp and fix the chainsaw casing, and can achieve a flexible clamping effect. Multiple clamping points can be used to ensure that the clamping is strong enough without damaging the chainsaw casing. The output mechanism 5 can adjust the clamping angle to adapt to different chainsaw casings, ensuring the flexible clamping effect and improving the versatility of this application. In addition, it should be noted that when drilling, the drilling component 2 controls the drilling punch 3 to automatically descend to perform the drilling operation. This is a conventional structure in the field, and this application does not limit it in detail.

[0033] Reference Figure 4 and Figure 5The clamping mechanism 6 includes a fixed plate 601 for support and fixation. A support plate 602 is fixedly connected to the middle of the top of the fixed plate 601. Fixed shafts 607 are fixedly connected to both sides of the top of the fixed plate 601. Clamping plates 608 are movably connected to the sides of both fixed shafts 607. A threaded rod 604 is movably connected inside the support plate 602. An adjusting wheel 603 is fixedly connected to the side of the threaded rod 604. The adjusting wheel 603 is located on the side of the support plate 602 away from the threaded rod 604. A threaded sleeve 605 is threadedly connected to the side of the threaded rod 604 away from the adjusting wheel 603. A top plate 606 is fixedly connected to the side of the threaded sleeve 605 away from the adjusting wheel 603. An extension plate 613 is fixedly connected to both the top and bottom of the top plate 606. A second connecting shaft 612 is fixedly connected to the inner sides of the extension plate 613 that are close to each other.

[0034] Each of the two second coupling shafts 612 has a connecting plate 611 movably sleeved on its side. The connecting plate 611, away from the second coupling shaft 612, is movably connected to a first coupling shaft 610. Locking plates 609 are fixedly connected to the top and bottom of the first coupling shaft 610. The side of the locking plate 609 away from the first coupling shaft 610 is fixedly connected to the side of the clamping plate 608. Flexible inner lining plates 614 are fixedly connected to the sides of the two clamping plates 608 away from the fixed shaft 607. The two ends of the flexible inner lining plates 614 are respectively connected to the clamping plates. The flexible inner liner 614 is fixedly connected to the middle part of the top plate 606 away from the threaded sleeve 605. The two clamping plates 608 are fixedly connected to the sides of each other with limit posts 615. The flexible inner liner 614 is located between the clamping plate 608 and the limit post 615. The two sides and the middle part of the flexible inner liner 614 are fixedly connected to the clamping plate 608 and the top plate 606 respectively. The contact part between the flexible inner liner 614 and the limit post 615 moves within the limit post 615.

[0035] In this embodiment, when the adjusting wheel 603 rotates forward and backward, the threaded rod 604 rotates forward and backward. When the threaded rod 604 rotates forward and backward, the threaded sleeve 605 moves closer to or further away from the adjusting wheel 603. When it moves closer, the top plate 606 drives the second connecting shaft 612 to move via the extension plate 613. When the second connecting shaft 612 moves, it drives the connecting plate 611 to rotate around the first connecting shaft 610, thereby causing the clamping plates 608 on both sides to rotate away from each other. At this time, the angle between the two clamping plates 608 increases, making it more suitable for larger chainsaw housings. When the top plate 606 moves away from the adjusting wheel 603, the angle between the two clamping plates 608 decreases, making it suitable for smaller chainsaw housings. Furthermore, when it moves closer, the angle between the two clamping plates 608 increases, and the top plate 606 moves closer to the support. When the support plate 602 moves away from the clamping plate 608, the angle decreases and the top plate 606 moves away from the support plate 602. This ensures that the top plate 606 and the side of the clamping plate 608 away from the support plate 602 are always close to the same plane, making the contact between the flexible inner lining plate 614 and the chainsaw shell more stable. The two sides of the flexible inner lining plate 614 are fixed to the side of the clamping plate 608 away from the support plate 602, while the center of the flexible inner lining plate 614 is fixed to the side of the top plate 606. The rest of the flexible inner lining plate 614 is separated from the clamping plate 608, but the limiting post 615 keeps the flexible inner lining plate 614 and the clamping plate 608 in a close fit. During adjustment, the flexible inner lining plate 614 can move between the limiting post 615 and the clamping plate 608, allowing the application to be adjusted normally.

[0036] Reference Figure 6 and Figure 7 The output mechanism 5 includes an output motor 501 that provides power. A bidirectional screw 502 is fixedly connected to the side of the output motor 501. The two sides of the bidirectional screw 502 are provided with threaded grooves that are mirror-symmetrical about the central plane of the drilling machine tool 1. A movable plate 503 is threadedly connected to the side of the threaded groove of the bidirectional screw 502. The top of the movable plate 503 is fixedly connected to the bottom of the clamping mechanism 6. A limit plate 504 is fixedly connected to the bottom of the movable plate 503. Limit rods 505 are movably connected to both sides inside the limit plate 504. The two ends of the limit rods 505 are fixedly connected to the inside of the drilling machine tool 1. The bidirectional screw 502 passes through the placement table 8 and is movably connected to the placement table 8.

[0037] In this embodiment, when the output motor 501 drives the bidirectional screw 502 to rotate, it will drive the moving plates 503 on both sides of it to move inward synchronously. When the bidirectional screw 502 moves, it will drive the clamping mechanism 6 above it to move inward as a whole. At this time, the two clamping mechanisms 6 move synchronously towards the chainsaw shell above the placement platform 8. The flexible inner lining plate 614 contacts the chainsaw shell, thereby flexibly clamping and fixing the chainsaw shell. The top plate 606 and the clamping plate 608 can support the flexible inner lining plate 614, ensuring the clamping effect of flexible clamping and fixing, and avoiding secondary damage to the chainsaw shell.

[0038] Reference Figure 2 and Figure 8 The smoke exhaust mechanism 7 includes an air intake 701 fixedly connected to the exhaust pipe 4. The air intake 701 is located at the bottom end of the exhaust pipe 4 and is connected to the exhaust pipe 4. A rotating motor 702 is provided on the side of the air intake 701 near the drilling machine tool 1. A rotating shaft 703 is fixedly connected to the side of the rotating motor 702. A blade assembly 704 is fixedly connected to the side of the rotating shaft 703. The blade assembly 704 is located inside the air intake 701 and consists of two sets. Both sets of blade assemblies 704 are located on the side of the exhaust pipe 4 away from the rotating motor 702. A sealing plate 705 is fixedly connected to the side of the rotating motor 702.

[0039] In this embodiment, the rotating motor 702 starts and drives the rotating shaft 703 to rotate. When the rotating shaft 703 rotates, it drives the two blade groups 704 on the side to rotate. When the blade groups 704 rotate, they absorb gas from the outside through the suction cylinder 701. The exhaust pipe 4 discharges the gas absorbed by the suction cylinder 701 through the exhaust pipe 4. The gas discharged from the exhaust pipe 4 blows onto the punch and the chainsaw housing, thereby cooling them down. Both blade groups 704 are located on the side of the exhaust pipe 4 away from the rotating motor 702, ensuring the absorption effect from the outside air and thus ensuring that the punch 3 does not overheat, allowing it to perform punching work for a long time.

[0040] The working principle of this invention is as follows: When drilling holes in the chainsaw casing, the chainsaw casing is placed above the placement platform 8. At this time, the adjusting wheel 603 is rotated according to the size of the chainsaw casing. When the adjusting wheel 603 rotates, it drives the threaded rod 604 to rotate. The forward and reverse rotation of the threaded rod 604 causes the threaded sleeve 605 to move closer to or away from the adjusting wheel 603. When the threaded sleeve 605 drives the top plate 606 to move closer to the adjusting wheel 603, the top plate 606 drives the second connecting shaft 612 to move through the extension plate 613. When the second connecting shaft 612 moves, it drives the connecting plate 611 to rotate around the first connecting shaft 610, thereby causing the clamping plates 608 on both sides to rotate away from each other. At this time, the angle between the two clamping plates 608 becomes larger, which is more suitable for larger chainsaw casings. When the top plate 606 moves away from the adjusting wheel 603, the angle between the two clamping plates 608 becomes smaller, which is suitable for smaller chainsaw casings.

[0041] When the angle between the two clamping plates 608 changes, the side of the clamping plate 608 away from the fixed axis 607 drives the flexible inner liner plate 614 to move. At this time, the flexible inner liner plate 614 moves on the side of the limiting post 615. Under the limitation of the limiting post 615, the flexible inner liner plate 614 maintains a close fit with the sides of the two clamping plates 608. At this time, the flexible inner liner plate 614 is located on the side of the clamping plate 608 and the extension plate 613. Figure 4 As shown, the limiting post 615 is located on the side of the extension plate 613 near the adjusting wheel 603, so it will not directly contact the chainsaw housing.

[0042] After adjusting the clamping mechanism 6, the output motor 501 starts and drives the bidirectional screw 502 to rotate. When the bidirectional screw 502 rotates, it drives the moving plates 503 on both sides to move inward synchronously. When the bidirectional screw 502 moves, it drives the clamping mechanism 6 above it to move inward as a whole. At this time, the two clamping mechanisms 6 move synchronously towards the chainsaw shell above the placement platform 8. The flexible inner lining plate 614 contacts the chainsaw shell, thereby flexibly clamping and fixing the chainsaw shell. The top plate 606 and the clamping plate 608 can support the flexible inner lining plate 614, ensuring the clamping effect of flexible clamping and fixing, and avoiding secondary damage to the chainsaw shell.

[0043] After the chainsaw housing is fixed, the rotating motor 702 starts and drives the rotating shaft 703 to rotate. When the rotating shaft 703 rotates, it drives the two blade groups 704 on the side to rotate. When the blade groups 704 rotate, they absorb gas from the outside through the suction cylinder 701. The exhaust pipe 4 will discharge the gas absorbed by the suction cylinder 701 through the exhaust pipe 4. The gas discharged from the exhaust pipe 4 will blow onto the drilling punch and the chainsaw housing, thereby cooling it down. Both blade groups 704 are located on the side of the exhaust pipe 4 away from the rotating motor 702, ensuring the absorption effect of the outside air and thus ensuring that the drilling punch 3 will not overheat, allowing it to perform drilling work for a long time.

[0044] In conclusion, the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
