Description

Technical Field

[0001] This utility model relates to the field of fire extinguisher processing, and in particular to a deburring and repair machine for the outer cylinder of a fire extinguisher. Background Technology

[0002] As a common fire-fighting equipment, the safety and precision of the manufacturing process of fire extinguishers are of paramount importance. The outer cylinder of the fire extinguisher is the core pressure-bearing component. However, after the welding process, weld slag, spatter, and uneven burrs are inevitably generated in the weld and its surrounding area. Therefore, deburring and surface finishing of the outer cylinder of the fire extinguisher is an essential and critical step in its production process.

[0003] Currently, the common method for deburring the outer cylinder of fire extinguishers is to rely on the operator's arm strength to press the cylinder against a grinding column and remove the burrs through friction. However, the quality of the entire deburring process is highly dependent on the operator's experience, physical strength, and concentration. Different operators can lead to huge differences in processing results. In some areas, the grinding may be overdone, damaging the cylinder base material and affecting its structural strength; in other areas, the grinding may be insufficient, leaving burrs and failing to meet quality standards. This instability and inconsistency makes it difficult to guarantee the product qualification rate, seriously affecting the smooth progress of subsequent processes and the overall quality of the final product. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a fire extinguisher outer cylinder deburring and repair machine. Through a locking component, the outer cylinder of the fire extinguisher is limited, replacing the dangerous operation of manually supporting the cylinder. This fundamentally eliminates the safety hazard of the operator's hands approaching the high-speed rotating grinding tool, and greatly improves the safety of the operation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fire extinguisher outer cylinder deburring and repair machine, comprising a repair machine body, a placement post rotatably connected to the bottom of the inner wall of the repair machine body, a rotating column rotatably connected to the inner wall of the placement post, a locking assembly provided on the outer wall of the rotating column, the rotating column limiting the fire extinguisher outer cylinder through the locking assembly, a motor fixedly connected to the left end of the outer wall of the repair machine body, the drive end of the motor penetrating through the inner wall of the repair machine body and fixedly connected to a threaded rod, a sliding plate threadedly connected to the outer wall of the threaded rod, a slider slidably connected to the top of the outer wall of the sliding plate, and the outer wall of the slider fixedly connected to the bottom end of the repair machine body.

[0006] Furthermore, the positioning assembly includes several fixing rings fixedly connected to the outer wall of the rotating column, with sliding columns slidably connected to both the upper and lower sides of the inner wall of the fixing rings, and a top block fixedly connected to the outer wall of the sliding column, the outer wall of the top block slidably connected to the inner wall of the placement pile.

[0007] Furthermore, the outer wall of the fixed ring is provided with rotating grooves on both the upper and lower sides, and the sliding column slides in the rotating grooves.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figure 2 - Figure 5This utility model provides an embodiment of a fire extinguisher outer cylinder deburring and repair machine, including a repair machine body 1. A placement post 4 is rotatably connected to the bottom of the inner wall of the repair machine body 1. A rotating column 26 is rotatably connected to the inner wall of the placement post 4. A locking assembly is provided on the outer wall of the rotating column 26. The rotating column 26 limits the fire extinguisher outer cylinder through the locking assembly. The locking assembly includes several fixing rings 24 fixedly connected to the outer wall of the rotating column 26. Sliding sliding connections are provided on both the upper and lower sides of the inner wall of the fixing rings 24. The moving column 21 and the sliding column 21 are fixedly connected to a top block 13. The outer wall of the top block 13 is slidably connected to the inner wall of the placement pile 4. The upper and lower sides of the outer wall of the fixing ring 24 are provided with rotating grooves 20. The sliding column 21 slides in the rotating grooves 20. The left end of the rotating column 26 is fixedly connected to a handle 5. The inner wall of the handle 5 is fixedly connected to an inner tube 23. The inner wall of the inner tube 23 is fixedly connected to a compression spring 25. The outer wall of the compression spring 25 is fixedly connected to a sliding rod 22. The outer wall of the sliding rod 22 is slidably connected to the handle 5. The inner wall of the machine body 1 has several slots 6 at the rear end of the outer wall of the placement pile 4. The size of the slots 6 is adapted to the slide bar 22. The left end of the outer wall of the machine body 1 is fixedly connected to the motor 2. The drive end of the motor 2 passes through the inner wall of the machine body 1 and is fixedly connected to the threaded rod 3. The outer wall of the threaded rod 3 is threadedly connected to the slide plate 10. The bottom end of the slide plate 10 is fixedly connected to the grinding wheel 12. The front end of the grinding wheel 12 is fixedly connected to the connecting rod 16. The front end of the connecting rod 16 is fixedly connected to the bottom end of the outer wall of the slide plate 10. A slider 11 is slidably connected to the top of the outer wall of the slide plate 10. The outer wall of the slider 11 is fixedly connected to the bottom of the repair machine body 1. A top plate 7 is fixedly connected to the right end of the outer wall of the repair machine body 1. A hydraulic rod 8 is rotatably connected to the bottom end of the top plate 7. A fixing block 9 is rotatably connected to the bottom end of the hydraulic rod 8. A rotating plate 15 is fixedly connected to the left end of the fixing block 9. The top of the rotating plate 15 is rotatably connected to the right side of the bottom end of the repair machine body 1. The bottom end of the inner wall of the rotating plate 15 is locked to the right end of the outer wall of the placement pile 4.

[0019] Specifically, the operator first activates hydraulic rod 8, causing it to retract. This retraction directly pulls rotating plate 15, causing it to rotate on the repair machine body 1. This moves rotating plate 15 away from the right end of placement stake 4, creating sufficient space for the subsequent insertion of the fire extinguisher outer cylinder. At this point, the right end of placement stake 4 is fully open, allowing the operator to easily and quickly insert the fire extinguisher outer cylinder from right to left onto placement stake 4 for initial positioning. After the fire extinguisher outer cylinder is inserted into placement stake 4, the operator manually... Pressing the slide bar 22 causes its front end to leave the slot 6 and be inserted into the handle 5, thereby releasing the rotation restriction of the handle 5. Simultaneously, the pressing action compresses the spring 25, storing elastic potential energy for subsequent reset operations. Then, the operator rotates the handle 5 backward. The handle 5 is coaxially fixed with the rotating column 26, so rotating the handle 5 directly drives the rotating column 26 to rotate synchronously. A fixing ring 24 is fixedly connected to the end of the rotating column 26. A groove 20 with a special trajectory is formed on the inner wall of the fixing ring 24. This groove 20 is a groove with an eccentric curve. When fixed... When ring 24 rotates together with rotating column 26, the groove 20 on its inner wall applies a thrust through sliding column 21. Since top block 13 is confined within the radial slide of placement post 4, it can only move linearly up and down. Therefore, the rotational motion of rotating column 26 is precisely converted into linear motion of top block 13 radially outward along placement post 4 through the linkage of fixed ring 24, groove 20, and sliding column 21. Then, as top block 13 protrudes outward from the inner wall of placement post 4, its end is evenly and forcefully pressed against the inner wall of the outer cylinder of the fire extinguisher, thus firmly restricting the outer cylinder from moving. The movement of the stake 4 prevents it from shifting or deflecting during the grinding process. Moreover, since the clamping force acts on the inner wall, it will not damage the outer surface of the outer cylinder, thus ensuring the appearance quality of the product. After clamping is completed, the operator releases the slide rod 22, and the compressed spring 25 immediately releases its elasticity, pushing the slide rod 22 out of the handle 5 and resetting it. The handle 5 is also relocked to prevent accidental loosening due to vibration during equipment operation. Finally, the reverse drive hydraulic rod 8 is used to retract it, causing the rotating plate 15 to rotate in the opposite direction and re-close the right end opening of the stake 4.

[0020] Reference Figure 1 , Figure 2 and Figure 6 A collection box 17 is fixedly connected to the front end of the outer wall of the repair machine body 1. A traction pipe 18 is fixedly connected to both the left and right sides of the slider 11. The rear end of the traction pipe 18 penetrates the inner wall of the repair machine body 1. A drawer 19 is provided on the inner wall of the traction pipe 18. The drawer 19 is used to store the metal dust after grinding. An exhaust fan 14 is fixedly connected to the top end of the traction pipe 18. A filter screen is provided at the bottom end of the inner wall of the exhaust fan 14. The filter screen is used to prevent the metal dust after grinding from entering the exhaust fan 14.

[0021] Specifically, the operator then starts motor 2. The output shaft of motor 2 is connected to threaded rod 3, driving threaded rod 3 to rotate at high speed. Through the rotation of threaded rod 3, the sliding plate 10 is driven to move along the guide rail of slider 11 installed on the repair machine, making precise and uniform horizontal linear reciprocating motion. As the sliding plate 10 moves axially along the outer cylinder of the fire extinguisher under the drive of threaded rod 3, the grinding wheel 12 will closely adhere to the weld seams and edges of the outer cylinder surface, performing continuous grinding and cutting. Since the outer cylinder has been firmly fixed, the feed depth and movement trajectory of the grinding wheel 12 are very stable, thus ensuring the consistency of burr removal effect and the smoothness of the processed surface. Then, at the same time as starting motor 2, the exhaust fan 14 is started. The strong suction of exhaust fan 14 acts on the inside of collection box 17, creating a negative pressure environment inside collection box 17. This negative pressure is transmitted to the surface of placement stake 4 through traction pipe 18. As soon as the metal dust generated by the friction between the grinding wheel 12 and the outer cylinder is produced, it is captured by the immediately generated powerful airflow. Then, the airflow carrying the metal dust is quickly sucked into the collection box 17 through the traction pipe 18 under negative pressure. Inside the collection box 17, the airflow must pass through the high-efficiency filter screen installed at the inlet of the exhaust fan 14. This filter screen can intercept metal dust particles, allowing clean air to be discharged through the fan. The intercepted metal dust falls into the drawer 19 designed at the bottom of the collection box 17 under the action of gravity. When the grinding wheel 12 completes a stroke or a preset grinding time, the equipment stops running. The operator first turns off the motor 2 and the exhaust fan 14. Then, in the reverse order of clamping, the operator operates the throttle 5 and the hydraulic rod 8 to release and remove the processed fire extinguisher outer cylinder. Finally, the drawer 19 is pulled out, which allows for convenient and centralized cleaning and treatment of the collected metal dust.

[0022] Working principle: First, drive the hydraulic rod 8, which drives the rotating plate 15 through the fixed block 9, causing the rotating plate 15 to leave the placement post 4. Then, the outer cylinder of the fire extinguisher that needs to be deburred can be placed on the placement post 4. Then, press the sliding rod 22, which enters the handle 5 from the slot 6 on the placement post 4 to release the restriction on the handle 5. At the same time, the sliding rod 22 squeezes the compression spring 25. Then, rotate the handle 5 backward, which drives the rotating column 26 to rotate. The rotating column 26 drives the fixed ring 24 to rotate, which drives the sliding column 21 to slide in the rotating groove 20 opened in the inner wall of the fixed ring 24. Then, the sliding column 21 drives the top block 13 to move outward in the inner wall of the placement post 4, so that the top block 13 protrudes from the placement post 4 and limits the upper and lower sides of the outer cylinder of the fire extinguisher. After the outer cylinder is limited, drive the hydraulic rod 8 in reverse, which causes the rotating plate 15 to close the right end of the placement post 4 again.

[0023] Then, by starting the motor 2 and the exhaust fan 14, the motor 2 drives the threaded rod 3 to rotate, causing the threaded rod 3 to drive the slide plate 10 to slide to the left on the slider 11. The slide plate 10 drives the grinding wheel 12 to move along the burr seam on the outer cylinder, so that the grinding wheel 12 grinds the restricted outer cylinder. Then, by starting the exhaust fan 14, the exhaust fan 14 draws air from the collection box 17, so that the collection box 17 draws air from the placement pile 4 through the traction pipe 18, collecting the dust generated when the grinding wheel 12 grinds the outer cylinder. The metal dust enters the collection box 17 through the traction pipe 18, and after being blocked by the filter screen on the exhaust fan 14, it falls into the drawer 19. After grinding and repair, the exhaust fan 14 is turned off and the drawer 19 is taken out to clean the metal dust in the drawer 19.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
