Description

Technical Field

[0001] This utility model relates to the field of quick replacement technology for curved arm bushings, and in particular to a device for quick replacement of curved arm bushings. Background Technology

[0002] The bushing is a key component of the radial sliding bearing. It adopts an integral tubular structure design and directly cooperates with the journal to support rotational motion. Its integrated construction simplifies the assembly process and is suitable for mechanical scenarios that require stable load-bearing and relative motion.

[0003] Curved arms are generally used in the glove production process to connect hand molds to the production line. They are typically hung on the shaft of the production line by a bushing at the end of the curved arm. During production, the curved arm bushing is prone to wear or other damage, requiring timely replacement of the internal bushing to reduce the failure rate and ensure stable production operation.

[0004] Replacing the internal bushing of the boom is relatively laborious. It requires removing the old bushing and then inserting the new bushing to ensure that the boom can still work normally. This process takes a lot of time, reduces the efficiency of the operators, and makes it difficult to ensure a low damage rate of the boom during bushing replacement.

[0005] Therefore, it is necessary to provide a device for quickly replacing the bent arm bushing to solve the above-mentioned technical problems. Utility Model Content

[0044] Please refer to the following: Figures 4-5 , Figure 4 A schematic diagram of the second embodiment of the device for quickly replacing the bent arm bushing provided by this utility model; Figure 5 Provided for this utility model Figure 4 The enlarged view at point B shows a device for quickly replacing the bend arm bushing based on the first embodiment of this application. The second embodiment of this application proposes another device for quickly replacing the bend arm bushing. The second embodiment is merely a preferred embodiment of the first embodiment, and its implementation will not affect the independent implementation of the first embodiment.

[0045] Specifically, the difference in the device for quickly replacing the curved arm bushing provided in the second embodiment of this application is that a base plate 27 is installed on the top of the mounting bracket 5, and sliding rods 24 are installed on the top of the base plate 27 near both sides via fixing plates 26, and fixing rods 18 are fixedly connected to the top ends of the two sliding rods 24.

[0046] The fixing rod 18 is used to increase the stability of the slide rod 24.

[0047] The outer surfaces of the two slide rods 24 are slidably connected to a movable frame 23. Two auxiliary springs 25 are installed at the bottom of the movable frame 23. A protective cover 20 is installed on the front of the movable frame 23. Iron plates 19 are installed on the top of the inner wall of the protective cover 20 near the two corners of the front.

[0052] Beneficial effects:

[0053] To enhance the safety of replacing the bushing 10 with the curved arm 12, two sliding rods 24 are mounted on the top of the base plate 27 via a fixing plate 26. Movable frames 23 are mounted on the outer surfaces of the two sliding rods 24 via auxiliary springs 25. The thrust provided by the auxiliary springs 25 allows the movable frames 23 to move the protective cover 20 upwards. In actual use, after placing the curved arm 12 and bushing 10, simply press down on the protective cover 20 to compress the auxiliary springs 25, causing the iron plate 19 to attract the magnetic plate 21 on the mounting rod 22. This allows the protective cover 20 to cover the replacement area of ​​the bushing 10. After replacement, simply lift the protective cover 20 upwards to separate the magnetic plate 21 from the iron plate 19. The protective cover 20 will then return to its original position due to the elasticity of the auxiliary springs 25. This design improves protection during bushing 10 replacement and enhances safety.
