Description

Technical Field

[0001] This invention belongs to the field of microparticle jet polishing technology, and specifically discloses a microparticle jet polishing device for the inner wall of a GIS switch housing. Background Technology

[0002] The GIS switch housing is a key load-bearing component of gas-insulated switchgear. The smoothness and cleanliness of the inner wall of the housing directly determine the insulation performance, sealing performance and long-term operational reliability of the equipment. After the housing is processed, it must be polished by microparticle jet polishing to remove burrs, oxide layers and processing defects.

[0003] Currently, traditional polishing and spraying devices have a fixed structural design, with the spray head only set in a single spray direction. This cannot fully cover complex areas such as the corners and grooves of the inner wall of the housing, resulting in limited polishing coverage, poor overall polishing uniformity, and a high risk of uneven polishing. In addition, the auxiliary spraying channels that are conventionally added tend to accumulate and stagnate abrasive particles during long-term operation, causing blockage of the spray nozzles. This not only leads to the failure of the auxiliary spraying function and the interruption of polishing operations, but also reduces the polishing accuracy and production efficiency of the housing. The equipment has high maintenance costs and is difficult to adapt to the batch polishing processing needs of high-precision GIS switch housings. Summary of the Invention

This effectively covers complex structures such as the corners and grooves of the inner wall of the GIS switch housing, eliminating polishing dead angles and improving polishing coverage and uniformity. By rotating synchronously with the adjusting ring, the striking rod periodically strikes the inner wall of the nozzle to generate high-frequency micro-vibration, which can clear the nozzle in real time and prevent the accumulation of fine sand particles that block the spray channel. No need to stop the machine for disassembly and cleaning, reducing the frequency of equipment failure and downtime, lowering maintenance costs, and is suitable for the mass polishing of GIS switch housings. By relying on springs, adjusting rings, and support structures to form a pressure-adaptive buffer structure, and with the main slide, secondary slide, and sliding ball working together, the internal structure of the nozzle is ensured to operate smoothly, thus improving the stability of the device's operation. The electric wheel drives the slide to slide back and forth, which drives the overall displacement of the sandblasting pipe and the spray head to make fine adjustments. Combined with the rotation of the spray head itself, it realizes dynamic polishing of the entire inner wall of the shell, adapting to the curved surface and grooved irregular structure of the shell, and improving polishing accuracy and work efficiency.

[0017] like Figures 1-11The device shown is a particle jet polishing device for the inner wall of a GIS switch housing. It includes a sandblasting chamber 1, a frame 2 fixedly mounted at the lower end of the sandblasting chamber 1, a sandblaster 3 mounted on the inner bottom of the frame 2, an auxiliary part 9 located on the inner bottom of the sandblasting chamber 1, a flow divider 6 mounted on the inner wall of the sandblasting chamber 1, a sandblasting pipe 7 mounted at the front end of the flow divider 6, and a nozzle 8 located at the front end of the sandblasting pipe 7.

[0018] A support ring 816 is fixedly installed on the outer side of the support rod 814 near the front side of the spring 815. A retaining ring 817 is movably installed on the outer side of the support ring 816. A docking bracket 818 is fixedly installed on the inner wall of the control ring 87. An installation groove 819 is opened on the outer side of the adjusting ring 812. A shaft 820 is fixedly installed on the inner wall of the installation groove 819. A striking rod 821 is movably installed on the outer side of the shaft 820. An elastic element 822 is installed on the bottom inner side of the installation groove 819. A contact head is fixedly installed at one end of the striking rod 821. 823, a striking head 824 is fixedly installed at one end of the striking rod 821 near the front side of the contact head 823; a connecting joint 825 is fixedly installed on the inner wall of the nozzle 81 near the spiral groove 84 and the control frame 89; a connecting rod 826 is fixedly installed at the front end of the adjusting ring 812; a flow divider groove 827 is opened at the rear end of the adjusting ring 812; a secondary sliding groove 828 is fixedly installed at the rear end of the fixed ring 85 near the outer side of the retaining ring 86; a split nozzle 829 is movably installed inside the movable hole 82; and the outer side of the retaining ring 86 is connected to the main sliding groove. The grooves 810 are fixedly connected. The outer side of the adjusting head 88 is slidably connected to the inner side of the spiral groove 84. The front end of the slider 811 is fixedly connected to the rear end of the support rod 814. The support rod 814 is slidably connected to the inner side of the secondary slide groove 828. The rear end of the spring 815 is fixedly connected to the front end of the support frame 813. The front end of the spring 815 is fixedly connected to the rear end of the support ring 816. The outer side of the support ring 816 is slidably connected to the inner side of the buckle 817 near the front side of the spring 815. The rear end of the buckle 817 is connected to the front side of the support frame 813. The end is fixedly connected to the outer side of the spring 815. The inner side of the docking frame 818 is slidably connected to the outer side of the support rod 814 near the front side of the support ring 816. One end of the elastic element 822 is installed at one end of the striking rod 821. The contact head 823 corresponds to the docking head 825. The front end of the connecting rod 826 is fixedly connected to the rear end of the control ring 87. The main body of the diversion groove 827 is spiral-shaped. The lower end of the nozzle 829 is fixedly connected to the bottom of the inner side of the cavity 83. The nozzle 829 and the nozzle 81 are interconnected.

[0019] After startup, the sandblaster 3 at the bottom of the frame 2 extracts the fine particles from the collection chamber 4, forming a high-pressure sandblasting mixed airflow. The airflow is transported through the pipe 5 to the distributor 6 for pressure stabilization and diversion, and then evenly introduced into the sandblasting pipe 7. Finally, it rushes into the nozzle 81 of the spray head 8 at high speed, providing stable power for the polishing operation. After the high-pressure sandblasting airflow enters the nozzle 81, it penetrates forward through the control frame 89. The air pressure pushes the adjusting ring 812 to move backward, causing the support frame 813 to slide along the support rod 814 and compress the spring 815. The spring 815 achieves pressure adaptive buffering. At the same time, the adjusting ring 812 pulls the control ring 87 to move through the connecting rod 826, causing the control head 88 of the control ring 87 to slide along the spiral groove 84 on the inner wall of the nozzle 81. The spiral structure converts linear displacement into rotational motion, driving the control ring 87 and the adjusting ring 812 to rotate synchronously. During operation, the support rod 814 can slide along the secondary slide groove 828, cooperating with the guide ball 811 in the main slide groove 810. To ensure stable structural operation, the retaining ring 817 and the docking frame 818 serve as limiters to prevent deviation. As the adjusting ring 812 rotates, the sandblasting airflow converges into the spiral-shaped diversion groove 827 at its rear end and forms a vortex. The fine sandblasting particles are ejected laterally through the nozzles 829 in the movable hole 82, while another portion passes through the central channel of the retaining ring 86 and the fixed ring 85 and is ejected from the front end of the nozzle 81, forming a multi-angle spraying pattern. This effectively covers the complex structure of the inner wall of the housing, eliminating polishing dead angles. Simultaneously, the striking rod 821 on the outer side of the adjusting ring 812 rotates synchronously with it. When the end contact head 823 touches and presses against the butt joint 825 on the inner wall of the nozzle 81, the striking rod 821 rotates around the shaft 820 as the fulcrum and presses against the elastic element 822, causing the striking head 824 to periodically strike the inner wall of the nozzle 81, generating high-frequency micro-vibration. This vibration can effectively clear the nozzle 829, prevent the accumulation and blockage of micro-particles, ensure uniform and smooth sandblasting output, and improve the polishing flatness.

[0020] The auxiliary unit 9 includes a base 91 fixedly installed at the bottom of the inner side of the sandblasting chamber 1. A disc 92 is fixedly installed at the upper end of the base 91. A slide rail 93 is fixedly installed on the outer side of the disc 92. A carriage 94 is slidably installed on the outer side of the slide rail 93. An electric wheel 95 is installed on the inner wall of the carriage 94. An adjustment frame 96 is fixedly installed at the upper end of the carriage 94. A support platform 97 is fixedly installed at the front end of the base 91. A clamp 98 is fixedly installed at the upper end of the support platform 97. The rear end of the carriage 94 is connected to the outer side of the slide rail 93. The inner side of the adjustment frame 96 is fixedly connected to the outer side of the sandblasting pipe 7. The clamp 98 is located above the disc 92.

[0021] Workers fill the collection chamber 4 with polishing-specific micro-particles for sandblasting. Then, they fix the GIS switch housing workpiece to be polished onto the clamp 98 on the bottom auxiliary part 9 inside the sandblasting chamber 1. The clamp 98 securely holds the workpiece, preventing it from shifting or shaking during polishing. After the workpiece is clamped, the control frame 96 of the auxiliary part 9 is adjusted. Using the sliding fit structure between the slide 94 and the slide rail 93, the position and insertion angle of the sandblasting pipe 7 and the front nozzle 8 are adjusted, and the nozzle 8 is precisely inserted into the polishing area inside the workpiece to complete the initial alignment and adjustment. During the polishing operation, the electric wheel 95 of the auxiliary part 9 drives the slide 94 to slide back and forth along the slide rail 93. The control frame 96 drives the overall displacement of the sandblasting pipe 7 and the nozzle 8 for fine adjustment. Combined with the rotation of the nozzle 8 itself, dynamic polishing of the entire inner wall of the GIS switch housing without dead angles is achieved. This effectively adapts to complex structures such as grooves and curved surfaces of the housing, significantly improving polishing accuracy and work efficiency.

[0022] Working principle: During use, the worker first fills the collection chamber 4 with polishing-specific micro-particles for sandblasting. Then, the GIS switch housing workpiece to be polished is fixedly installed on the clamp 98 of the auxiliary part 9 at the bottom inside the sandblasting chamber 1. The clamp 98 securely holds the workpiece, preventing it from shifting or shaking during polishing. After the workpiece is clamped, the control frame 96 of the auxiliary part 9 is adjusted. Using the sliding fit structure between the slide 94 and the slide rail 93, the position and insertion angle of the sandblasting pipe 7 and the front nozzle 8 are adjusted, and the nozzle 8 is precisely inserted into the area to be polished inside the workpiece, completing the initial alignment and debugging. After startup, the sandblaster 3 at the bottom of the frame 2 draws the micro-particles from the collection chamber 4, forming a high-pressure sandblasting mixed airflow. The airflow is transported through the pipe 5. After being regulated and diverted by the distributor 6, the airflow is evenly introduced into the sandblasting pipe 7 and finally flows at high speed into the nozzle 81 of the spray head 8, providing stable power for the polishing operation. The high-pressure sandblasting airflow enters the nozzle 81 and penetrates forward through the control frame 89. The air pressure pushes the adjusting ring 812 backward, causing the support frame 813 to slide along the support rod 814 and compress the spring 815. The spring 815 provides pressure adaptive buffering. Simultaneously, the adjusting ring 812 pulls the control ring 87 to move via the connecting rod 826, causing the control ring 87's adjusting head 88 to slide along the spiral groove 84 on the inner wall of the nozzle 81. The spiral structure converts linear displacement into rotational motion, driving the control ring 87 and the adjusting ring 812 to rotate synchronously. During operation, the support rod... 814 can slide along the secondary slide groove 828, and with the guidance of the sliding ball 811 in the main slide groove 810, it ensures the smooth operation of the structure. The retaining ring 817 and the docking frame 818 play a role in limiting and preventing deviation. As the adjusting ring 812 rotates, the sandblasting airflow converges into the spiral diversion groove 827 at its rear end and forms a vortex. The sandblasting particles are sprayed laterally through the nozzle 829 in the movable hole 82, and another part passes through the central channel of the retaining ring 86 and the fixed ring 85 and is sprayed from the front end of the nozzle 81, forming a multi-angle spraying mode, which effectively covers the complex structure of the inner wall of the shell and eliminates polishing dead angles. At the same time, the striking rod 821 on the outside of the adjusting ring 812 rotates synchronously with it. When the end contact head 823 and the docking joint 825 on the inner wall of the nozzle 81 are connected, the sandblasting airflow is directed to the main slide groove 812. When touched and squeezed, the striking rod 821 rotates around the shaft 820 and squeezes the elastic device 822, causing the striking head 824 to periodically strike the inner wall of the nozzle 81, generating high-frequency micro-vibration. This vibration can effectively clear the sub-nozzle 829, prevent the accumulation and blockage of micro-particles, ensure uniform and smooth sandblasting output, and improve the polishing flatness. During the polishing operation, the electric wheel 95 of the auxiliary part 9 drives the slide 94 to slide back and forth along the slide rail 93. Through the control frame 96, the overall displacement of the sandblasting pipe 7 and the nozzle 8 is finely adjusted. Combined with the rotation and spraying of the nozzle 8 itself, dynamic polishing operation of the entire inner wall of the GIS switch housing without dead angles is realized. It can effectively adapt to complex structures such as housing grooves and curved surfaces, and significantly improve polishing accuracy and work efficiency.Multi-angle spraying modes are achieved through nozzle 81. Fine abrasive particles can be sprayed laterally from the sub-nozzle 829 or from the front of nozzle 81, effectively covering complex structures such as corners and grooves on the inner wall of the GIS switch housing, eliminating polishing dead angles, and improving polishing coverage and uniformity. The striking rod 821 rotates synchronously with the adjusting ring 812, periodically striking the inner wall of nozzle 81 to generate high-frequency micro-vibrations. This can clear the sub-nozzle 829 in real time, automatically preventing fine abrasive particles from accumulating and clogging the spraying channel. No downtime for disassembly and cleaning is required, reducing equipment downtime frequency and lowering maintenance costs. This technology is compatible with GIS switch housings. In the mass polishing of IS switch housings, a pressure-adaptive buffer structure is formed by spring 815, adjusting ring 812, and support frame 813. Simultaneously, the main slide groove 810, secondary slide groove 828, and sliding ball 811 work together to ensure smooth operation of the internal structure of the spray head 8, improving the stability of the device's operation. The electric wheel 95 drives the slide 94 to reciprocate, causing fine-tuning of the overall displacement of the sandblasting pipe 7 and spray head 8. Combined with the rotational spraying of the spray head 8, dynamic polishing of the entire inner wall of the housing is achieved, adapting to curved surfaces and irregularly shaped grooves of the housing, improving polishing accuracy and work efficiency.
