Description

Technical Field

[0001] This utility model relates to the field of explosion-proof valve top cover processing technology, specifically a rapid drilling device for the vent hole of an explosion-proof valve top cover. Background Technology

[0002] The explosion-proof valve top cover is a key component of the explosion-proof valve, primarily used to ensure equipment safety under abnormal pressure conditions. It is commonly used in equipment such as boilers and pressure vessels. When abnormal pressure fluctuations occur, such as in thermal power plant units where abnormal operation of the boiler's forced and induced draft fans leads to excessively high induced draft head in the furnace, coupled with a rapid decrease in fuel input or a total fuel trip, causing a sharp drop in furnace flue gas and pressure that could trigger an implosion, the explosion-proof valve top cover, in conjunction with other components of the explosion-proof valve, can preemptively replenish air into the relevant equipment, preventing permanent deformation of the furnace and serious consequences such as flue gas explosions.

[0003] Existing CNC machine tools only support single-hole machining, which cannot meet the needs of multi-hole synchronous machining, resulting in limited production capacity; frequent manual contact with high-speed drill bits poses a risk of workplace injury; if flying debris is not cleaned up in time during aluminum alloy machining, it may damage the precision parts of the equipment; under traditional drilling methods, a worker can only operate a maximum of 1-2 machines, making it difficult to improve production efficiency.

[0015] Compared with the prior art, this utility model provides a rapid drilling device for the vent hole of the explosion-proof valve top cover, which has the following beneficial effects:

[0016] 1. The rapid drilling device for the vent hole of the explosion-proof valve top cover has a feeding tray and a discharging tray.

It reduces aluminum alloy debris generation, producing less dust compared to traditional solutions, eliminating dust risk, and ensuring that dust and debris generated during processing will not affect subsequent processing.

[0020] The spindle motors, arranged in a ring around the outside of the four-jaw gas disc, operate synchronously in all four directions when machining the explosion-proof valve top cover. They drill holes in the explosion-proof valve top cover using a drill bit, completing multi-hole machining in a single operation and improving machining efficiency.

When processing the explosion-proof valve top cover 6, the spindle motors 2202 in the four directions work synchronously, and drill holes in the explosion-proof valve top cover 6 through the drill bit 2203, completing multi-hole processing in one go, which improves processing efficiency.

[0043] Example 3

[0044] See Figure 2 , Figure 3 and Figure 7 Furthermore, based on Embodiment 1 and Embodiment 2, the material transfer mechanism 3 includes an X-axis assembly 31 and a Y-axis assembly 32. The X-axis assembly 31 is located on the top of the worktable 41, behind the positioning mechanism 1, and the Y-axis assembly 32 is located on top of the X-axis assembly 31.

[0045] The X-axis assembly 31 includes an X-module slide 3101, which is positioned above the rear drilling mechanism 2. A support rod 3102 is fixedly connected to the bottom of the X-module slide 3101 and to the top of the worktable 41. An observation camera 3103 is fixedly connected to the front of the X-module slide 3101 and is aligned with the top of the gripper fixture 1202. A servo motor 3104 is fixedly connected to the inner right side of the X-module slide 3101. The top of the X-module slide 3101 slides... The Y-axis assembly 32 includes a Y-module slide 3201, which is fixedly connected to the top of the movable slide 3105. A servo motor 3202 is fixedly connected to the rear inner side of the Y-module slide 3201. A slide frame 3203 is slidably connected to the right side of the Y-module slide 3201. An air blowing device 3204 is fixedly connected to the right side of the slide frame 3203. A suction cup structure 3205 is provided on the rear side of the air blowing device 3204. The suction cup structure 3205 is fixedly connected to the right side of the slide frame 3203.

[0046] Furthermore: the workbench 41 and the feeding tray 42 work together, with each tray accommodating 35 / 70 explosion-proof valve top covers 6. The overall structure of the material transfer mechanism 3 enables unmanned loading and unloading, breaking through the traditional single-piece processing mode.

[0047] In actual operation, when this device is used, the feeding tray 42, which is covered with the explosion-proof valve top cover 6, is first placed on the top of the workbench 41. Then, the second servo motor 3104 is started, driving the moving slide 3105 to slide on the top of the X module slide 3101. At the same time, the third servo motor 3202 is started, driving the slide 3203 to slide on the right side of the Y module slide 3201. The two work together to move the suction cup structure 3205 to the top of the workbench 41 and align it with the explosion-proof valve top cover 6. The suction cup structure 3205 then secures the explosion-proof valve top cover 6. The explosion valve top cover 6 is adsorbed and picked up. Then the air blowing device 3204 continues to move to the top of the gripper fixture 1202. Then the suction cup structure 3205 starts to spray air onto the explosion valve top cover 6 adsorbed at the bottom of the air blowing device 3204, releasing the adsorption of the explosion valve top cover 6 by the air blowing device 3204, so that the explosion valve top cover 6 falls into the top of the gripper fixture 1202. Then the gripper fixture 1202 retracts inward to clamp and fix the explosion valve top cover 6. At this time, the fixing of the explosion valve top cover 6 is completed.

[0048] Then, the four corner servo motors 2102 start and drive the slide table 2103 to move inward synchronously. The inward movement of the slide table 2103 drives the drill bit 2203 to move inward through the motor clamp 2201 and the spindle motor 2202. At the same time as the servo motor 2102 starts, the four corner spindle motors 2202 start synchronously. The start of the spindle motor 2202 drives the drill bit 2203 to start. The start of the drill bit 2203 contacts the four corners of the outer ring of the explosion-proof valve top cover 6 to complete the drilling of the outer ring of the explosion-proof valve top cover 6.

[0049] Afterwards, the gripper fixture 1202 unlocks and releases the gripper on the explosion-proof valve top cover 6. Then, servo motor 2 3104 and servo motor 3202 start the moving air blowing device 3204 to the top of the explosion-proof valve top cover 6 to adsorb the explosion-proof valve top cover 6. Then, the explosion-proof valve top cover 6 is moved to the top of the discharge tray 43. Then, the suction cup structure 3205 is activated to make the explosion-proof valve top cover 6 fall into the top of the discharge tray 43. At this time, the processing of the explosion-proof valve top cover 6 is completed.
