Description

Technical Field

[0001] This utility model relates to the field of automotive air conditioning compressor cylinder block manufacturing technology, and more specifically, it relates to a cleaning device for the production and processing of automotive air conditioning compressor cylinder blocks. Background Technology

[0002] The cleaning device for automotive air conditioning compressor cylinder block production and processing refers to a special equipment specifically designed for efficient and high-cleanliness cleaning of the compressor cylinder block (i.e., the core housing component that houses the piston, swashplate, or scroll assembly) after machining, heat treatment, or assembly processes during the manufacturing of automotive air conditioning compressors.

[0003] Traditional automotive air conditioning compressor cylinder cleaning devices typically employ a multi-station, step-by-step process of "soaking first, then transferring to the spray area for rinsing" when cleaning the inside of the cylinder cavity. The cylinder needs to be moved or transferred multiple times between the soaking tank and the spray area, resulting in dispersed processes, frequent transfers, low cleaning efficiency, slow production cycle, and the need to set up multiple independent functional areas (soaking tank, spray room), making the equipment complex and occupying a large area.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a cleaning device for the production and processing of automotive air conditioning compressor cylinder blocks, which aims to solve the technical problems of low cleaning efficiency and complex equipment structure with large footprint.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a cleaning device for the production and processing of automotive air conditioning compressor cylinder blocks, including a workbench, a cleaning tank fixedly installed at the upper end of the workbench for cleaning the compressor cylinder block, a drain pipe movably connected to the upper end of the workbench, the drain pipe passing through the bottom center of the cleaning tank and extending into the cleaning tank, a diverter pipe fixedly installed at the top end of the drain pipe, multiple nozzles with filter screens distributed circumferentially on the side wall of the diverter pipe, and a nozzle with a filter screen provided at the top of the diverter pipe, a fixing plate fixedly connected to the lower outer side of the drain pipe, and a first electric cylinder fixedly installed on the upper right side of the workbench, the telescopic end of the first electric cylinder extending vertically downward and fixedly connected to the fixing plate, for driving the drain pipe and water tank as a whole to move up and down in the cleaning tank to adjust the spray height and perform multi-angle rinsing of the cylinder block cavity.

[0007] The present invention is further configured such that: a fixed frame is fixedly installed on the upper rear side of the workbench, a second electric cylinder is fixedly installed on the top of the fixed frame, and a positioning pressure plate is fixedly installed on the output end of the second electric cylinder. The second electric cylinder drives the positioning pressure plate 11 at its output end to move vertically downward, and the positioning pressure plate presses against the top of the cylinder body to position and fix the compressor cylinder body.

[0008] The present invention is further configured such that the center lines of the positioning pressure plate and the cleaning tank coincide, ensuring that when the second electric cylinder drives the positioning pressure plate to press down, the pressure is applied vertically along the central axis of the cylinder body, so that the inverted compressor cylinder body remains coaxially aligned after being pressed, avoiding skewness or unilateral force.

[0009] The present invention is further configured such that a flexible water supply pipe is fixedly installed at the bottom of the drain pipe.

[0010] The present invention is further configured such that: a first drain pipe is fixedly installed on the bottom left side of the cleaning tank for discharging cleaning waste liquid in the cleaning tank; and a second drain pipe is fixedly installed on the bottom middle side of the cleaning tank, located outside the drain pipe, for receiving and discharging the rinsing water flowing down through the compressor cylinder.

[0011] The present invention is further configured such that: five nozzles are provided and are evenly distributed circumferentially on the outer surface sidewall of the diverter.

[0012] The present invention is further configured such that: a discharge chute is provided on the upper left side of the workbench, the discharge chute is located directly below the first sewage pipe and the second sewage pipe, the discharge chute serves as a centralized guide channel for waste liquid, receiving the discharged liquid from the two sewage pipes, and its "inclined" structure uses gravity to automatically guide the waste liquid to an external collection box or treatment system.

[0013] In summary, this utility model has the following beneficial effects:

[0014] This device integrates short-time retention cleaning and spraying into the same workstation, requiring only one clamping to complete all cleaning actions. This significantly shortens the processing time per piece, meets the cycle time requirements of modern high-speed production lines, and significantly improves cleaning efficiency. It solves the problems of "dispersed processes and slow cycle time." Furthermore, because it eliminates the need for separate soaking tanks, spray chambers, and transfer mechanisms, the entire machine has a compact structure, consisting only of a workbench, cleaning tank, lifting spray components, and dual drain pipes. This makes it easy to integrate into automated production lines, reduces factory space requirements, simplifies equipment structure, and reduces the floor space required. Attached Figure Description

[0022] The present invention will now be described in detail with reference to the accompanying drawings.

[0023] A cleaning device for the production and processing of automotive air conditioning compressor cylinder blocks, such as Figures 1 to 3As shown, the system includes a workbench 1, with a cleaning tank 2 fixedly installed on the upper end of the workbench 1 for cleaning the compressor cylinder. A drain pipe 3 is movably connected to the upper end of the workbench 1, passing through the bottom center of the cleaning tank 2 and extending into the cleaning tank 2. A diversion pipe 4 is fixedly installed at the top of the drain pipe 3, with multiple nozzles 5 with filter screens distributed circumferentially on the side wall of the diversion pipe 4, and a nozzle 6 with a filter screen is installed at the top of the diversion pipe 4. A fixing plate 7 is fixedly connected to the lower outer side of the drain pipe 3. A first electric cylinder 8 is fixedly installed on the upper right side of the workbench 1, with the telescopic end of the first electric cylinder 8 extending vertically downward and fixedly connected to the fixing plate 7. This cylinder is used to drive the drain pipe 3 and the entire water tank to move up and down within the cleaning tank 2 to adjust the spray height and perform multi-angle rinsing of the cylinder cavity. Removable stainless steel filters with an 80μm pore size are provided at the inlet of the nozzles 5 and 6 to intercept metal debris in the cleaning fluid and prevent nozzle clogging. The filters are installed via threaded connections for easy periodic cleaning or replacement.

[0024] like Figure 1 As shown, a fixed frame 9 is fixedly installed on the upper rear side of the workbench 1, a second electric cylinder 10 is fixedly installed on the top of the fixed frame 9, and a positioning pressure plate 11 is fixedly installed on the output end of the second electric cylinder 10.

[0025] like Figure 1 As shown, the center lines of the positioning plate 11 and the cleaning tank 2 coincide, ensuring that when the second electric cylinder 10 drives the positioning plate 11 to press down, the pressure is applied vertically along the central axis of the cylinder body, so that the inverted compressor cylinder body remains coaxially aligned after being pressed, avoiding skewness or unilateral force.

[0026] A flexible water supply pipe 12 is fixedly installed at the bottom of the drain pipe 3. The flexible water supply pipe 12 connects the external water supply system to the liftable drain pipe 3 and serves as the inlet channel for the cleaning fluid. Its "flexible" characteristics (such as metal braided hose or pressure-resistant rubber hose) allow the drain pipe 3 to move freely up and down under the drive of the first electric cylinder 8 without pipe breakage or leakage.

[0027] A first drain pipe 13 is fixedly installed on the bottom left side of the cleaning tank 2 for discharging the cleaning waste liquid in the cleaning tank 2. A second drain pipe 14 is fixedly installed on the bottom middle side of the cleaning tank 2, located outside the drain pipe 3, for receiving and discharging the rinsing water flowing down through the compressor cylinder. The first drain pipe 13 is responsible for emptying the overflow liquid or main waste liquid accumulated in the cleaning tank 2. The second drain pipe 14 is directly below the opening of the inverted cylinder and is specifically used to collect the highly polluted rinsing water flowing directly from the inside of the cylinder.

[0028] Five nozzles 5 are provided and are evenly distributed circumferentially on the outer surface sidewall of the split pipe 4. The five nozzles are evenly arranged at equal angles (72° intervals) along the circumference of the split pipe 4 to form a 360° horizontal spray coverage. The spray direction is directly towards the inner wall of the inverted cylinder body, the oil passage inlet and the side cavity area.

[0029] A discharge chute 15 is provided on the upper left side of the workbench 1. The discharge chute 15 is located directly below the first sewage pipe 13 and the second sewage pipe 14. The discharge chute 15 serves as a centralized guide channel for waste liquid, receiving the discharged liquid from the two sewage pipes. Its "inclined" structure uses gravity to automatically guide the waste liquid to an external collection box or treatment system.

[0030] Working principle: The compressor cylinder to be cleaned is placed upside down in the cleaning tank 2 with the opening facing down and the bottom facing up. At this time, the diversion pipe 4, which is fixedly installed at the top of the drain pipe 3, and the spray head 5 and nozzle 6 on it naturally extend into the internal cavity of the cylinder, preparing for subsequent cleaning.

[0031] The second electric cylinder 10 at the top of the mounting bracket 9 is activated, driving the positioning plate 11 at its output end to move vertically downwards. The positioning plate 11 presses against the top of the cylinder body. Under the combined action of the cylinder body's own weight and the axial pressure applied by the positioning plate 11, the bottom of the cylinder body fits tightly against the bottom plane of the cleaning tank 2. This fitting structure effectively reduces the gap between the cylinder body and the tank bottom, preventing subsequent cleaning fluid from overflowing from the bottom in large quantities. Even if there is a small amount of leakage, it will fall into the cleaning tank 2 and be collected, avoiding external leakage that could contaminate the equipment or the environment.

[0032] The external water supply system continuously supplies cleaning fluid to the drain pipe 3 through the flexible water pipe 12. After being distributed by the diversion pipe 4, the cleaning fluid is simultaneously sprayed out from the following two paths: five circumferentially evenly distributed nozzles 5 spray outwards at a 360° angle horizontally, covering the inner wall and side cavities of the cylinder; and the top nozzle 6 sprays vertically upwards in a circular diffusion pattern, fully covering the inner surface of the top of the cylinder cavity. The sprayed cleaning fluid quickly fills the entire interior of the cylinder, performing in-situ cleaning of complex structures such as deep holes, intersecting oil passages, and annular grooves. The cleaning fluid is continuously sprayed through the nozzles 5 and 6, providing high-pressure flushing and short-term retention cleaning of the inside of the cylinder, softening and initially removing attached oil and metal debris.

[0033] After the short-term retention cleaning is completed, the highly concentrated polluted waste liquid inside the tank flows out from the tank opening under gravity and falls directly into the second drain pipe 14 located at the bottom center of the cleaning tank 2, achieving directional and efficient discharge of the rinsing water inside the tank. At the same time, the cleaning liquid that overflows into the cleaning tank 2 due to the tank being inverted, such as the liquid accumulated at the bottom of the tank, is discharged through the first drain pipe 13 on the left side.

[0034] After a short-term cleaning cycle, the first electric cylinder 8 can be activated. The first electric cylinder 8 drives the connected fixing plate 7, which in turn drives the drain pipe 3 and the diversion pipe 4 to move up and down within the cylinder cavity. During this lifting and lowering process, the nozzles 5 and 6 continuously spray high-pressure cleaning fluid, dynamically and comprehensively rinsing different height areas of the cylinder, especially the bottom of the deep cavity, corners, and oil passage inlets—traditionally blind spots—thoroughly removing residual impurities. The circumferential arrangement of the nozzles 5 ensures no dead corners on the inner wall, while the circular spray pattern of the nozzles 6 effectively covers the top area. Together, they achieve three-dimensional cleaning.

[0035] All discharged waste liquid flows from the first drain pipe 13 and the second drain pipe 14 to the discharge chute 15 on the upper left side of the workbench 1. The discharge chute 15 adopts an inclined structure design, which uses gravity to automatically guide the waste liquid to an external waste liquid recycling or treatment system. At this point, the entire cleaning cycle is completed, and the operator can take out the cleaned cylinder and proceed to the next process for subsequent drying.

[0036] In summary, traditional methods require multiple cylinder handling, which is time-consuming. This device integrates short-term retention cleaning and spraying into the same workstation, requiring only one clamping to complete all cleaning actions, significantly shortening the processing time per piece, meeting the cycle time requirements of modern high-speed production lines, significantly improving cleaning efficiency, and solving the problems of "dispersed processes and slow cycle time". Moreover, since it eliminates separate soaking tanks, spray chambers, and transfer mechanisms, the whole machine has a compact structure, consisting only of a workbench 1, a cleaning tank 2, a lifting spray assembly, and dual drain pipes, making it easy to integrate into automated production lines, reducing factory space requirements, simplifying equipment structure, and reducing floor space.

[0037] It is worth noting that the electric cylinder disclosed in the above embodiments is specifically the Festo EGC series, and the operation of the electric cylinder by the external control switch group and the external power supply adopts a method commonly used in the prior art.

[0038] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
