Description

Technical Field

[0001] This invention relates to the technical field of hydraulic cylinder manufacturing and processing. More specifically, this invention relates to a processing machine for a helical oscillating hydraulic cylinder. Background Technology

[0002] The spiral swing cylinder is a special hydraulic cylinder that uses a spiral pair with a large helix angle to achieve rotational motion. Its end cap is disc-shaped and has six threaded holes arranged in a ring. In the current technology, when painting the outer surface of the end cap, in order to avoid spraying paint into the threaded holes, a masking plate is usually placed over the end of the threaded hole before the painting operation. However, the diameter of the masking plate is slightly larger than that of the threaded hole, which prevents paint from being sprayed around the end face of the threaded hole. This results in the end cap rusting during subsequent use. If the bolts are screwed into the threaded holes before painting the outer surface of the end cap, the paint on the bolts and the paint on the surface of the end cap will connect with each other. When the bolts need to be unscrewed later, the hardened paint layer on the outer surface of the end cap will crack.

At the same time, the threaded post is aligned with the thread path on the part to be painted by the cooperation of the slider and the spring before being screwed in, avoiding direct screwing and damaging the threads on the part to be painted. Meanwhile, the second cylinder blows air downward to dry the water on the rod and the threaded post. During use, the first blade is rotated to blow air downward to dry the water on the rod and the threaded post, avoiding the impact of liquid on the next painting operation. Moreover, the first blade is driven to rotate by the rod, eliminating the need for an additional drive component for drying, which helps to save costs.

[0017] During cleaning, the threaded column is cleaned in two stages using bristles and an electric telescopic scraper. By rotating the second blade, the sewage inside the third cylinder is drawn out to the outside, and clean water flows into the third cylinder, which improves the paint dissolution efficiency on the threaded column and further improves the cleaning efficiency.

[0018] In addition, after the spraying is completed, the receiving unit is removed and the parts to be painted are transferred to other processes through the receiving unit to achieve assembly line operation. Attached Figure Description

All six connecting rods 2010 are inserted into the part to be painted 2013. The two magnetic components 2012 are magnetically connected to the part to be painted 2013. The upper edge of the connecting rod 2010 is chamfered. The magnetic component 2012 is a magnet.

[0038] The lifting unit includes a connecting block 2016, a second telescopic cylinder 2017, and a first linkage block 2018; the connecting block 2016 is welded between the two first support frames 3; two second telescopic cylinders 2017 are fixedly connected to the upper side of the connecting block 2016; the first linkage block 2018 is fixedly connected between the telescopic ends of the two second telescopic cylinders 2017.

[0039] The sealing unit located at the front includes a slider 2019, a second linkage block 2020, a spring 2021, a round rod 2022, and a threaded column 2023; the slider 2019 is slidably connected to the front side of the first linkage block 2018; the second linkage block 2020 is bolted to the upper side of the slider 2019; two springs 2021 are welded to the lower side of the second linkage block 2020; the lower ends of the two springs 2021 are welded to the first linkage block 2018; the round rod 2022 is rotatably connected inside the second linkage block 2020; the threaded column 2023 is welded to the lower end of the round rod 2022.

[0040] The front drying unit includes a first blade 2024 and a second cylinder 2025; six first blades 2024 are welded in a ring on the outer surface of the round rod 2022; a second cylinder 2025 is welded between two first blades 2024; the second cylinder 2025 is funnel-shaped.

[0041] The drive unit includes a first motor 2026, a first gear 2027, and a second gear 2028; the first motor 2026 is fixedly connected to the upper middle part of the first linkage block 2018; the first gear 2027 is fixedly connected to the output end of the first motor 2026; six second gears 2028 are meshed on the first gear 2027; the six second gears 2028 are respectively connected to the adjacent sealing unit; the second gear 2028 located at the front is fixedly connected to the round rod 2022.

[0042] During preparation, the external feed pipe is manually connected to the spray head 204. The part to be painted 2013 is manually inserted into the upper end of the six connecting rods 2010, and the lower side of the part to be painted 2013 is brought into contact with the support ring 2011 and the magnetic component 2012. The magnetic component 2012 fixes the part to be painted 2013 with magnetic force. Then, the second base plate 209 is inserted into the receiving plate 208, and then the fixing block 2015 is pushed backward, so that the fixing block 2015 moves to the upper side of the second base plate 209, fixing the second base plate 209 onto the receiving plate 208. Figure 5 As shown, the installation process is complete;

[0043] After installation, the second telescopic cylinder 2017 drives the first linkage block 2018 to move downwards. The first linkage block 2018 drives the parts on it to move downwards, causing the threaded post 2023 to move downwards and contact the threaded hole on the part to be painted 2013. At the same time, the first motor 2026 is started. The first motor 2026 drives the first gear 2027 to rotate, the first gear 2027 drives the second gear 2028 to rotate, the second gear 2028 drives the round rod 2022 to rotate, and the round rod 2022 drives the threaded post 2023 to rotate, thereby screwing the threaded post 2023 into the threaded hole on the part to be painted 2013. Then, the external supply pipe delivers paint to the paint spray head 204. 204. Paint is sprayed onto the surface of the part to be painted 2013. At the same time, the robotic arm 203 changes the position of the paint spray head 204 in real time. The electric turntable 202 drives the robotic arm 203 to perform reciprocating circular motion, so that the paint spray head 204 sprays paint from various angles onto the surface of the part to be painted 2013, completing the paint spraying process. In use, the threaded post 2023 blocks the threaded hole on the part to be painted 2013. Compared with the existing technology of attaching the baffle to the threaded hole, the threaded post 2023 does not block the area around the end face of the threaded hole of the part to be painted 2013, thus solving the problem that the area around the end face of the threaded hole of the part to be painted 2013 is not sprayed with paint after the existing equipment is sprayed.

[0044] When the threaded post 2023 is screwed into the bolt hole on the part to be painted 2013, the threaded post 2023 cannot be aligned with the thread path of the threaded hole on the part to be painted 2013 as soon as it comes into contact with the threaded hole. Instead, the threaded post 2023 tends to move downward. At this time, the first linkage block 2018 moves downward relative to the slider 2019 and stretches the spring 2021 on the second linkage block 2020, thereby stopping the threaded post 2023 from moving in the vertical direction until the rotating threaded post 2023 is completely aligned with the threaded hole on the part to be painted 2013. Then, the rotating post is screwed downward into the threaded hole on the part to be painted 2013. In use, the slider 2019 and the spring 2021 cooperate to make the threaded post 2023 align with the thread path on the part to be painted 2013 before screwing it in, avoiding direct screwing and damaging the threads on the part to be painted 2013.

[0045] After the spraying is completed, the first motor 2026 drives the first gear 2027 to reverse, and at the same time the second telescopic cylinder 2017 drives the first linkage block 2018 to move upward, thereby unscrewing the threaded post 2023, turning off the first motor 2026, and then manually pulling the fixing block 2015 forward away from the second base plate 209, and then taking out the second base plate 209 and the parts on it, that is, taking out the receiving unit. The part to be painted 2013 is transferred to other processes for processing through the receiving unit. Multiple sets of receiving units can be set up to realize assembly line operation.

[0046] Implementation Plan 2

[0047] Based on implementation plan 1, such as Figure 1-2 and Figure 9-11 As shown, the cleaning assembly includes a connecting frame 301, a second motor 302, a third gear 303, a fourth gear 304, a brushing unit, and a scraping unit. The connecting frame 301 is welded to the upper inner side of the first cylinder 206. The second motor 302 is fixedly connected to the middle of the upper side of the connecting frame 301. The output shaft of the second motor 302 is fixedly connected to the third gear 303. Six brushing units are connected in a circular array on the connecting frame 301. A fourth gear 304 is fixedly connected to the lower side of each of the six brushing units. All six fourth gears 304 mesh with the third gear 303. A scraping unit is connected to each of the six brushing units.

[0048] The front brushing unit includes a third cylinder 305, bristles 306, and second blades 307; the third cylinder 305 is rotatably connected to the front of the connecting frame 301; several bristles 306 are fixed to the inner side of the third cylinder 305; and six second blades 307 are welded in a ring array on the lower inner side of the third cylinder 305.

[0049] The scraping unit located at the front includes a slide rail 308, an electric telescopic scraper 309, and an elastic telescopic rod 3010; the slide rail 308 is welded to the front inner side of the third cylinder 305; the electric telescopic scraper 309 is slidably connected to the slide rail 308; an elastic telescopic rod 3010 is fixedly connected to both the upper and lower sides of the slide rail 308; the telescopic ends of the two elastic telescopic rods 3010 are fixedly connected to the electric telescopic scraper 309.

[0050] After the spraying is completed, some paint will remain on the threaded post 2023. After the receiving unit is removed, the first telescopic cylinder 205 drives the first cylinder 206 to move upward. The first cylinder 206 drives the parts on it to move upward, causing the third cylinder 305 to move to the outside of the threaded post 2023. At this time, the clean water in the first cylinder 206 submerges the threaded post 2023. The second motor 302 is started, and the second motor 302 drives the third gear 303 to rotate. The third gear 303 drives the fourth gear 304 to rotate. The fourth gear 304 drives the third cylinder 305 to rotate. The third cylinder 305 drives the bristle 306 to perform a circular motion, so that the bristle 306 brushes off the paint on the surface of the threaded post 2023. At the same time, the third cylinder 305 drives the six second blades 307 to rotate, thereby drawing the sewage inside the third cylinder 305 to the outside and allowing clean water to flow into the third cylinder 305, improving the paint dissolution efficiency on the threaded post 2023.

[0051] When the third cylinder 305 moves to the outside of the threaded post 2023, the electric telescopic scraper 309 extends, causing its end to engage in the threaded groove of the threaded post 2023. The second motor 302 drives the third gear 303 to reciprocate, causing the third cylinder 305 to reciprocate. The third cylinder 305 then drives the parts on it to reciprocate, causing the electric telescopic scraper 309 to reciprocate around the thread of the threaded post 2023, scraping away the paint in the groove of the threaded post 2023, further improving cleaning efficiency. During this process, the electric telescopic scraper 309 moves upward or downward under the guidance of the thread of the threaded post 2023. The electric telescopic scraper 309 slides in the slide rail 308 and moves against the elastic telescopic rod 3. 010 Compress or stretch; after cleaning, the first telescopic cylinder 205 drives the first cylinder 206 to move downward back to its original position, and the first cylinder 206 drives the parts on it to move back to their original position. The first motor 2026 is started, so that the round rod 2022 drives the first blade 2024 to rotate, thereby blowing air downward through the second cylinder 2025 to dry the water on the round rod 2022 and the threaded column 2023. In use, by rotating the first blade 2024 to blow air downward, the water on the round rod 2022 and the threaded column 2023 is dried, avoiding the impact of liquid on the next painting operation. Moreover, the rotation of the first blade 2024 driven by the round rod 2022 does not require an additional drive component for drying, which helps to save costs.
