Description

Technical Field

[0001] This utility model belongs to the field of acid pickling technology for the inner cavity of bottle parts, and specifically relates to a non-powered flipping device for acid pickling the inner cavity of bottle parts. Background Technology

[0002] In aviation equipment maintenance, metal bottle-type parts used to store compressed air and fire extinguishing agents often develop internal corrosion after a refurbishment period, requiring acid pickling to clean the rust. The acid pickling process is as follows: degreasing → hot water wash → cold water wash → acid pickling → cold water wash → drying. To prevent cross-contamination between processes, the solution inside the bottle must be completely emptied after each process, once the bottle is full and held for a certain period, before moving it to the next process. Traditional bottle-type part acid pickling production lines use an overhead crane to immerse the bottle-type parts, supported by specialized fixtures, into the solution. The bottle-type parts are held upright within the fixture to ensure the solution fills the internal cavity. After a certain processing time, another electric lifting mechanism on the overhead crane uses a steel cable to pull the bottom of the fixture upwards, lifting the bottle-type parts so that the bottle-type parts are tilted downwards, thus emptying the solution. This method has the following problems: First, manual intervention is required after each process to start the electric mechanism to pour the solution in the bottle, which results in high labor costs and low efficiency. Second, when an electric mechanical device is used to pull the steel cable to pour the solution after each process, the investment in the production line is large. In addition, when the electric device works in the pickling atmosphere, the components of the electric device are easily corroded under the pickling conditions, resulting in a high failure rate and poor reliability. Utility Model Content

[0003] The purpose of this invention is to address the problems of high production line investment, high labor costs, low production efficiency, and poor reliability associated with existing electromechanical devices for acid washing of the inner cavity of bottle parts. This invention provides a non-powered tilting device for acid washing the inner cavity of bottle parts. This device uses a purely mechanical structure and automatically fills and pours the solution into the metal bottle during different process flows without external power. Furthermore, this device is compact, simple in structure, and highly versatile, enabling non-powered tilting of gas cylinder parts of various sizes and specifications. This improves the reliability, production efficiency, and safety of aerospace equipment repair while saving on production line hardware costs.

[0004] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0005] A non-powered flipping device for acid pickling of the inner cavity of bottle parts is provided, including a cage-like clamp, a hanger, and two buoyancy balls;

[0006] Cage-shaped clamps are used to hold and fix parts whose inner cavities are to be pickled;

[0007] The hanger is used to connect the cage clamp to the trolley and includes a rope and a hook. The rope is fixed to the bottom end of the cage clamp, and the hook is used to connect to the trolley attachment point so that the cage clamp can be placed into the pickling solution in an upside-down manner and pulled out of the solution by the trolley.

[0008] The two buoyancy balls are a first flipping buoyancy ball and a second buoyancy ball, both connected to the bottle mouth end of the cage-like clamp. The first flipping buoyancy ball can tilt the bottle mouth of the part when the part is placed into the pickling solution, so as to allow the solution to enter the part. The second buoyancy ball can make the part vertically suspended in the solution after the pickling solution enters the part.

[0009] Furthermore, the second buoyancy ball is a double-eared buoyancy ball, with its two protruding ears symmetrically fixed to the bottle mouth end of the cage-shaped clamp along the circumference of the cage-shaped clamp.

[0010] Furthermore, the first flipping buoyancy ball is a single-ear buoyancy ball, with its lug connected near the bottle mouth end of the cage-like clamp.

[0011] Furthermore, the rope is connected to the cage clamp via a locking device.

[0012] Furthermore, the cage-like clamp is made of a material resistant to corrosion from acid pickling solutions.

[0013] Furthermore, the net buoyancy of the second buoyancy ball is the weight of the cage-like clamp and the part after assembly in the solution, excluding its own buoyancy, plus the predetermined load.

[0014] Furthermore, the predetermined load is 10N.

[0015] The advantages of this utility model are:

[0016] This invention relates to a non-powered tilting device for acid pickling of bottle-shaped parts. The parts are housed in a cage-like clamp, with the bottom of the clamp connected to a trolley. Two buoyancy balls are connected to the bottle opening. One ball tilts the bottle opening to allow the acid pickling solution to enter, while the other ball keeps the parts suspended in the solution. Thus, after the bottle is filled with solution and held for a certain period before being moved to the next process, the trolley simply pulls the bottom of the clamp to tilt the parts, thereby emptying the solution. Therefore, this device uses a purely mechanical structure to achieve fully automated solution filling and emptying during the chemical processing of bottle-shaped parts on a production line, requiring no additional power. This improves the efficiency of aerospace equipment repair, saves on production line hardware costs, and offers high reliability. Attached Figure Description

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] Furthermore, terms such as "first" and "second" are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0026] This invention provides a non-powered tilting device for acid washing of bottle parts, which is used to automatically fill and pour out the solution when the bottle parts are transferred to different processes.

[0027] First refer to Figure 1 The bottle-type part internal acid pickling non-powered flipping device, which is an exemplary embodiment of the present utility model, includes a cage-shaped clamp 1, a hanging fixture 2, and two buoyancy balls, namely a first flipping buoyancy ball 3 and a second buoyancy ball 4.

[0028] The cage-like clamp 1 is used to accommodate and fix the parts in the inner cavity to be pickled, and is preferably made of a material resistant to the corrosion of pickling solution.

[0029] The hanging device 2 is used to connect the cage clamp 1 to the crane, and includes a rope 21 and a hook 22. The rope 21 can be a steel cable, which is fixed to the bottom end of the bottle of the cage clamp 1 and can be connected to the cage clamp 1 by a cable lock. The hook 22 is used to connect to the crane hanging point so that the cage clamp 1 can be placed into the pickling solution in an upside-down manner by the crane and pulled out of the solution.

[0030] Both buoyancy balls are made of PVC and are connected to the bottle mouth end of the cage-like clamp 1. The first flipping buoyancy ball 3 tilts the bottle mouth of the part when it is placed in the pickling solution, allowing the solution to enter the part. The second buoyancy ball 4 keeps the part vertically suspended in the solution after the pickling solution enters it. The first flipping buoyancy ball 3 can be a single-ear buoyancy ball, with its lug connected near the bottle mouth end of the cage-like clamp 1. Preferably, the second buoyancy ball 4 is a double-ear buoyancy ball, with its two lugs 41 symmetrically fixed to the bottle mouth end of the cage-like clamp 1 along the circumference of the cage-like clamp 1. The net buoyancy of the second buoyancy ball 4 is the weight of the cage-like clamp 1 and the part after assembly in the solution, excluding its own buoyancy, plus a predetermined load, which can optionally be 10N.

[0031] The working process of the non-powered flipping device for acid washing of bottle parts provided by this utility model is described below.

[0032] First, before starting the pickling process, open the cage-like clamp 1 and insert the metal bottle; then, fix the entire device to the trolley's mounting point using the hanger 2; set the trolley's operating parameters according to the solution filling and pouring time and the dwell time at each stage. Then, start the trolley, and the device automatically completes the pickling of the metal bottle with the assistance of the trolley. Figure 2 As shown, the device has a steel cable connecting the bottom of the clamp before entering the solution, with the bottle opening facing downwards. When the metal enters the solution to a certain depth, due to the action of the first buoyancy ball 3 at the bottle opening, the metal bottle becomes unbalanced in the solution and begins to tip over, with the bottle opening facing upwards at a certain angle, allowing the solution to begin entering the metal bottle, as shown. Figure 3 As shown. When the solution inside the metal bottle is full, the metal bottle moves downwards in the solution. After reaching a certain depth, it is pulled by the second buoyancy ball 4, ensuring that the metal bottle remains suspended in the solution, as shown. Figure 4 As shown. After maintaining this position for a certain period of time, the crane lifts the bottle upwards. Once it reaches a certain height, the steel cable pulls the bottom of the metal bottle, causing the bottle opening to tilt downwards and pour the solution out.

[0033] Therefore, as described above, according to this invention, the part is housed in a cage-like fixture. The bottom end of the fixture is connected to a trolley, and the mouth end is connected to two buoyancy balls. One buoyancy ball tilts the mouth of the bottle to ensure that the pickling solution can enter the bottle, while the other buoyancy ball allows the part to suspend in the solution after being filled. Thus, before transferring the part to the next process after the solution in the bottle is filled and held for a certain period, the part can be flipped by simply pulling the bottom of the fixture with the trolley, thereby emptying the solution inside the bottle. Therefore, this device uses a purely mechanical structure to achieve fully automated filling and emptying of solutions in the chemical processing production line for bottle-type parts by means of trolley movement, without requiring additional power. This improves the efficiency of aerospace equipment repair, saves hardware costs on the production line, and has high operational reliability.

[0034] Finally, it should be noted that the features mentioned and / or shown in the above description of exemplary embodiments of the present invention can be combined in the same or similar manner with one or more other embodiments, combined with features in other embodiments, or substituted for corresponding features in other embodiments. These combined or substituted technical solutions should also be considered as included within the protection scope of the present invention.
