Description

Technical Field

[0001] This utility model relates to the technical field of aluminum alloy cleaning equipment, specifically a cleaning device for the manufacturing and processing of aerospace aluminum alloys. Background Technology

[0002] During the processing of aerospace aluminum alloy profiles, it is necessary to clean them to remove cutting oil, coolant and residues from the surface. Currently, ultrasonic cleaning tanks with built-in cleaning agents are mostly used for cleaning aluminum alloy profiles.

[0003] A search revealed a convenient aluminum alloy pipe cleaning device in patent application publication number CN213316623U. This device involves placing the aluminum alloy pipe into a cleaning tank through the gaps between partitions. The pipe slides down the partitions, compressing an elastic buffer pad. A return spring then cushions the pipe as it falls into the cleaning tank, simultaneously rinsing both the inner wall and surface. After cleaning, an electric door is opened, and the pipe slides down the inclined surface at the bottom of the cleaning tank onto a slanted filter screen in the recovery tank. This method allows for the rapid and thorough cleaning of multiple aluminum alloy pipes, and both unloading and removal are very convenient.

[0004] This cleaning equipment cleans aluminum alloy profiles by placing them on a partition plate and conveying them into a cleaning tank. While it achieves the desired cleaning effect, it is only suitable for shorter aluminum alloy profiles. For longer profiles, a hoisting method is currently used, where the profiles are placed in sections within a hoisting frame and then immersed as a whole in a cleaning tank for acid immersion cleaning. However, due to the stacking of aluminum profiles, the hoisting cleaning efficiency is not high enough. Utility Model Content

[0005] The purpose of this utility model is to provide a cleaning device for the manufacturing and processing of aerospace aluminum alloys. By installing serpentine steel wire ropes on both sides of the hoisting frame, and fixing a rope with bristles between the two sets of steel wire ropes, when the drive structure drives the steel wire ropes to retract and release, the ropes reciprocate within the partition of the aluminum alloy profile. By contacting the surface of the aluminum alloy profile with the ropes, the cleaning efficiency is improved.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a cleaning device for manufacturing and processing aerospace aluminum alloys, comprising a hoisting frame and a rope structure capable of scraping the surface of aluminum alloy square tubes, wherein a partition rod capable of arranging aluminum alloy square tubes in layers is fixed inside the hoisting frame, and a driving structure capable of driving the rope structure to pass through the layers of aluminum alloy square tubes is installed on both sides of the hoisting frame.

[0007] The rope structure includes a rope, the outer wall of which is fixed with bristles, and both ends of the rope are provided with connecting structures for connection to the drive structure.

[0008] Preferably, the drive structure includes a wire rope and a winding motor for winding the wire rope and an unwinding motor for unwinding the wire rope. The winding motor and the unwinding motor are both fixed to the top of the hoisting frame by screws, and the output ends of the winding motor and the unwinding motor are respectively fixed with a winding roller and an unwinding roller.

[0009] Preferably, the drive structure further includes guide wheels for guiding the wire rope, and support rods are fixed at each of the four corners of the hoisting frame, with the guide wheels rotatably connected to one side of the support rods;

[0010] The guide wheels are provided in several units, and the wire ropes are provided in two sets.

[0011] Preferably, the connecting structure includes a connecting rod, one end of which is welded to the outer wall of the wire rope, and the other end of which is bent into a closed loop. Both ends of the rope are respectively bolted to two closed loops. Several sets of ropes and connecting rods are provided, and several ropes are arranged in parallel.

[0012] Preferably, the hoisting frame includes a base plate supporting the aluminum alloy profile, and the two sides of the base plate are welded with fences to protect the sides of the aluminum alloy profile, and the two ends of the partition rod are respectively welded to two sets of fences;

[0013] The separator bars are provided in several groups, and the several groups of separator bars are arranged longitudinally at equal intervals.

[0014] Preferably, each of the four corners at the top of the fence is welded with a hanging ring for hoisting, and the bottom plate is hollowed out.

[0015] Preferably, the two ends of the hoisting frame are fixed with limiting frames that limit the movement of the two ends of the aluminum alloy square tube by screws, and a mesh is fixed in the middle of the limiting frame.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This invention uses a serpentine arrangement of double steel wire ropes to drive multiple sets of parallel ropes to reciprocate between the profile layers. The brush bristles contact the profile surface underwater, which can improve the efficiency of the cleaning fluid in removing oil and residue. It is especially suitable for long aviation aluminum alloy profiles.

[0018] By modularizing the connection structure, the bristle-equipped ropes are replaceable, making it particularly suitable for batch cleaning of large-size aluminum alloy square tubes for aviation applications. Compared to traditional immersion cleaning, this device can solve the problem of insufficient contact during the hoisting and cleaning of long-size aviation aluminum alloy profiles, thereby improving cleaning efficiency.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0026] Please see Figure 1-5 This utility model provides a technical solution: a cleaning device for manufacturing and processing aviation aluminum alloy, including a hoisting frame 1 and a rope structure 2 capable of scraping the surface of aluminum alloy square tubes. The hoisting frame 1 is fixed with a separator rod 3 that can arrange the aluminum alloy square tubes in layers. The hoisting frame 1 is equipped with a driving structure 4 on both sides that can drive the rope structure 2 to pass through the layers of aluminum alloy square tubes.

[0027] The rope structure 2 includes a rope 201, the outer wall of which is fixed with bristles 202, and the two ends of the rope 201 are provided with connecting structures 5 for connecting to the drive structure 4.

[0028] By setting up a rope 201, when the rope 201 moves laterally within the partition between two adjacent aluminum alloy square tubes, the bristles 202 come into contact with the surface of the aluminum alloy square tubes, which can improve the cleaning efficiency of oil stains on the surface of the aluminum alloy square tubes underwater.

[0029] The parallel array of bristles 202 forms an interlaced contact pattern during reciprocating motion. Each square centimeter is equipped with 120-150 nylon composite bristles 202, which, with a preset cutting depth of 5-8mm, form a continuous wiping trajectory on the profile surface.

[0030] The drive structure 4 includes a wire rope 405, a winding motor 401 for winding the wire rope 405, and an unwinding motor 402 for unwinding the wire rope 405. The winding motor 401 and the unwinding motor 402 are both fixed to the top of the hoisting frame 1 by screws. The output ends of the winding motor 401 and the unwinding motor 402 are respectively fixed with a winding roller 403 and an unwinding roller 404.

[0031] The winding motor 401 and the unwinding motor 402 are synchronously controlled to drive the alternating winding and unwinding motion of the two sets of wire ropes 405.

[0032] The drive structure 4 also includes a guide wheel 406 for guiding the wire rope 405. Support rods 6 are fixed at the four corners of the hoisting frame 1. The guide wheel 406 is rotatably connected to one side of the support rod 6.

[0033] Several guide wheels 406 are provided, and two sets of steel wire ropes 405 are provided.

[0034] Two sets of steel wire ropes 405 are used to drive the two ends of rope 201 to move synchronously.

[0035] The connecting structure 5 includes a connecting rod 501. One end of the connecting rod 501 is welded to the outer wall of the wire rope 405. The other end of the connecting rod 501 is bent into a closed loop 502. The two ends of the rope 201 are respectively bolted to two closed loops 502. Several sets of ropes 201 and connecting rod 501 are provided. Several sets of ropes 201 are arranged in parallel.

[0036] By setting up connecting rod 501 and closed loop 502, both ends of rope 201 can be connected to closed loop 502 for easy replacement.

[0037] The hoisting frame 1 includes a base plate 101 that supports the aluminum alloy profile. The base plate 101 has railings 102 welded to both sides to protect the sides of the aluminum alloy profile. The two ends of the dividing rod 3 are respectively welded to two sets of railings 102.

[0038] The separator rod 3 is provided in several groups, and the several groups of separator rod 3 are arranged longitudinally at equal intervals.

[0039] The four corners at the top of the fence 102 are each welded with a hanging ring 103 for hoisting, and the base plate 101 is hollowed out. In use, the hanging rings 103 are lifted by an external hoisting machine, so that the hoisting frame 1 lifts the aluminum alloy profile and immerses it in the cleaning tank for cleaning.

[0040] The lifting frame 1 has a limiting frame 104 fixed to both ends of the aluminum alloy square tube by screws, which limits the movement of both ends. A mesh 105 is fixed to the middle of the limiting frame 104. By setting the limiting frame 104 and the mesh 105, it is easy to limit the movement of both ends of the aluminum alloy square tube.

[0041] When in use, place the aluminum alloy square tube profiles on top of the divider bar 3. After stacking, use an external hoisting machine to lift the hanging ring 103, so that the hoisting frame 1 lifts the aluminum alloy profiles and immerses them in the cleaning tank for soaking and cleaning.

[0042] During soaking, the winding motor 401 and the unwinding motor 402 are driven synchronously, causing the two sets of steel wire ropes 405 to move alternately in and out. When the two sets of steel wire ropes 405 move synchronously, they drive the rope 201 to move within the gaps of the aluminum alloy profile. The bristles 202 simultaneously contact the upper surface of the bottom layer of aluminum alloy profile and the lower surface of the upper layer of aluminum alloy profile, which can improve the efficiency of the cleaning solution in removing oil residues, and is especially suitable for long aviation aluminum alloy profiles.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
