Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical manufacturing, and in particular relates to a high-pressure cleaning machine without dead angles. Background Art

[0002] During the use of the car, a substance called sludge will be produced on the surface of the engine, which greatly increases the probability of engine failure. At the same time, it is not easy to find problems on the surface of the wiring harness. Furthermore, the dirt covering the surface of the engine will affect the heat dissipation of the engine, resulting in excessive temperature in the engine compartment, which will affect the service life of the engine on the one hand, and increase the aging of internal components of the engine compartment such as the wiring harness on the other hand, posing a safety hazard. In addition, the engine usually runs in a relatively closed compartment and will produce a high temperature of more than 100°C. The temperature is even higher in summer. If it is not cleaned and maintained regularly, the external components of the engine will be corroded, rusted, aged, cracked, etc., which will reduce the heat dissipation function of the engine and increase fuel consumption. In severe cases, it will ignite cracks and leak flammable oil stains, causing failure.

[0003] Therefore, it is very necessary to clean the engine casing (hereinafter referred to as the product). However, since the inner and outer surfaces of the engine casing are both uneven, there are cleaning dead corners during manual cleaning, and there are also uneven cleaning quality during manual cleaning, which increases labor and labor costs. Therefore, robots or manipulators are usually used in the prior art to replace manual grasping of products for automated cleaning to reduce labor intensity and labor costs. However, the cost of using robots is expensive, and since the surface of the product is uneven, it is not convenient for robots to grasp. Furthermore, since the grasping force is controlled by the system, when using robots to grasp the product, there is a situation where the surface of the product is deformed due to excessive force, which affects the normal use of the product; finally, whether it is manual grasping or robot grasping, the part of the product that contacts the clamp is difficult to clean in one go, and there is a problem of cleaning dead corners.

[0004] The cleaning machine can be used to flush and filter the pollutants generated or invaded during the manufacturing, manufacturing, assembly, use and maintenance of the hydraulic system; it can also be used for regular maintenance and filtration of the working oil to improve the cleanliness, avoid or reduce failures caused by pollution, so as to ensure the high performance, high reliability and long life of the hydraulic system equipment. Therefore, it is also common in the prior art to use a cleaning machine to achieve automatic cleaning of products. The structure of the cleaning machine can refer to patent CN110314892A, "A cleaning device for an engine and a gearbox housing". The cleaning machine disclosed by the prior art including this patent can solve the need for one-time cleaning products, but the overall equipment is large in size and has certain requirements for placement space. In addition, when using the prior art including this device for cleaning, multiple conveying devices are required, and in order to achieve all-round cleaning, a flip spray device needs to be added between the two conveying devices, and the products are transported to each cleaning tank in turn for cleaning through the conveying device; that is, the prior art requires multiple process processing during cleaning, the cleaning stroke is long, and there are many operating processes, so its cleaning efficiency is low.

[0005] Furthermore, patent CN217017832U discloses "an automatic cleaning and flipping device based on chain conveying technology". This device can effectively shorten the cleaning time by setting a flipping component on the cleaning table, driving the product to be cleaned to rotate through the flipping component, and cleaning at the same time. During use, it was found that the technical solution has the following shortcomings: 1. The main function of the cleaning table is to convey the product to be cleaned. When the product moves to the position of the flipping component, it needs to be shut down and restarted after the cleaning is completed. Multiple start and stop operations will greatly shorten the service life of the cleaning table, thereby increasing the cost of later maintenance and even replacement. 2. When the product to be cleaned is flipped by the flipping component, since there is no fixing device on the periphery of the product, and it cannot be guaranteed that the product fits the inner wall of the flipping component, the stability of the product cannot be guaranteed during the flipping process, and bumps may occur, affecting the product quality. 3. The flip assembly includes a high-pressure water pipe and a high-pressure nozzle, so the outer surface of the product is cleaned indiscriminately during the cleaning process. Since the local structure of some products is relatively delicate, high-pressure cleaning will cause certain damage to their structure or parts during cleaning, so this will not be suitable for the cleaning of such products; and there is no need to use high-pressure cleaning for some dust or non-stubborn stains attached to the product. 4. Since the high-pressure nozzles are distributed at equal distances along the cleaning table, when the product is conveyed, the two end faces set along the conveying direction will not be fully cleaned, and there will be blind spots for cleaning.

[0006] Designing a high-pressure cleaning machine without dead angles is an important technical problem that those skilled in the art need to solve. Utility Model Content

[0028] The purpose, advantages and features of the present invention will be illustrated and explained through the non-limiting description of the following preferred embodiments. These embodiments are only typical examples of the application of the technical solution of the present invention, and any technical solution formed by equivalent replacement or equivalent transformation falls within the scope of protection claimed by the present invention.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance. Moreover, in the description of the scheme, with the operator as a reference, the direction close to the operator is the proximal end, and the direction away from the operator is the distal end.

[0030] like Figure 1 to Figure 2 As shown, the utility model discloses a high-pressure cleaning machine without dead angles, comprising a power transmission device 1, a flip device 2 spanning the power transmission device 1, and a cleaning device 3 arranged above the flip device 2. The flip device is arranged across the power transmission device, so that the product reaches the flip device under the drive of the power transmission device, and cooperates with the cleaning device under the action of the flip device to achieve all-round and dead angle-free cleaning of the product; and resets after cleaning is completed, and then outputs by the power transmission device; the power transmission device does not need to be stopped for operation throughout the whole process, thereby extending its service life.

[0031] like Figure 1As shown, the power transmission device 1 is a conveyor line, on which a placement groove 10 is provided; and the flip device 2 on the placement groove 10 is provided with a position sensor 224 for sensing whether there is a product, and drives the flip device 2 to start after receiving a confirmation signal. When the product is placed on the power transmission device 1, its axis is consistent with the conveying direction of the power transmission device 1, and when it reaches the position sensor 224, it is clamped by the flip device 2 and flipped.

[0032] Further, as shown in the figure Figure 1 and Figure 3 As shown, the flip device 2 includes a driving mechanism 21 arranged on both sides of the power transmission device 1 and a flip frame 22 arranged between the driving mechanisms 21. Specifically, the driving mechanism 21 includes a driving motor 211 fixed on a driving fixed seat 210, and a hollow rotating shaft 212 driven to rotate by the driving motor 211; the rotating shaft 212 passes through the fixed seat 210 and the flip frame 22 is arranged at its far end. In the present application, it is preferred to design one of the driving mechanisms 21 as an active driving mechanism and the other as a passive driving mechanism. It can be seen that after starting the driving mechanism 21, it drives the flip frame 22 to rotate, and the rotation direction of the flip frame 22 is consistent with the conveying direction of the power transmission device 1.

[0033] like Figure 3 As shown, the overturning frame 22 includes a turntable 222 fixedly connected to the distal end of the rotating shaft 212, a connecting roller 223 connecting two of the turntables 222, and a second conveying roller 221 arranged at the bottom of the overturning frame 22. The position sensor 224 is arranged at the bottom of the overturning frame 22 and is preferably arranged in the center; further, the position sensor 224 is arranged between any two of the second conveying rollers 221. After the active driving mechanism of the driving mechanism 21 is started, the turntable 222 will drive the connecting roller 223 to rotate, and the driving force is transmitted through the connecting roller 223, thereby realizing the rotation of the above-mentioned driven driving mechanism. The second conveying roller 221 is located on the same plane as the first conveying roller 11 on the power transmission device 1, and is driven by the second power driving device 220. Further, the second power driving device 220 is arranged on the outer side of any of the turntables 222, and drives the second conveying roller 221 to move.

[0034] Further Figure 3 to Figure 4As shown, the connecting roller 223 is distributed in a rectangular shape and is located above and below the second conveying roller 221; that is, the turntable 222 is fixedly connected to the connecting roller 223 to form a cage-like structure, and the turntable 222 is located at the mounting groove 10. A space for accommodating products is formed between the connecting roller 223 located at the upper layer and the second conveying roller 221.

[0035] like Figures 2 to 3 As shown, in order to prevent the product from shaking after being placed in the space, the present application is provided with clamping assemblies 4 on both sides and the top of the flip frame 22; the clamping assembly includes an upper clamping member 41 and a side clamping member 42. At least one upper clamping member 41 is fixed on the connecting roller 223 located on the upper layer, and moves toward the direction of the second conveying roller 221 to adapt to the height of the product. The number of the upper clamping members 41 can be adjusted according to demand and is not limited here. The upper clamping member 41 and the second conveying roller 221 are used to fix the product in the vertical direction to reduce the shaking amplitude of the product.

[0036] like Figure 3 As shown, the side clamping members 42 are symmetrically arranged on the two rotating disks 222, and the side clamping members 42 and the upper clamping member 41 are driven by a cylinder. The side clamping members 42 include clamping rods 421 distributed in a rectangular shape on the rotating disk 222, and clamping plates 422 arranged opposite to each other. The clamping rods 421 and / or the clamping plates 422 can be selectively activated according to the product model. The side clamping members 42 apply a force to both sides of the product to fix the product in the horizontal direction, further reducing the shaking amplitude of the product; the upper clamping member and the side clamping member are combined to effectively ensure the stability of the product during the flipping process.

[0037] Further, such as Figure 3 to Figure 4 As shown, each of the upper clamping member 41 and the side clamping member 42 is provided with a corresponding in-place sensor 40, and the in-place sensor 40 detects whether the upper clamping member 41 or the side clamping member 42 is clamped in place, so as to ensure the stability of the clamped product. The signal connection line of the in-place sensor 40 penetrates from the outer periphery of the rotating shaft 212 near its position and passes out along its axial direction until it is connected with the rotary joint 213 at the end of the rotating shaft 212; the rotary joint 213 is located at the end of the rotating shaft 212 away from the turntable 222. It can be seen that after the product is clamped and the flip frame 22 drives the flipping process, the signal connection line of each in-place sensor 40 will not be entangled or broken, ensuring that each in-place sensor 40 can work effectively during the operation, and extending the service life of the in-place sensor.

[0038] The inner side of the rotating disk 222 is also provided with Figures 1 to 4The spray box 5 shown has a spray pipe extending from the periphery of the spray box 5 to the inside thereof; a group of spray ports 50 for connecting a low-pressure spray head are arranged on the side thereof, and the low-pressure spray head cleans the outer wall of the product. The spray box 5 supplies water to the low-pressure spray head, and the low-pressure spray head cleans the outer wall of the product at low pressure, thereby ensuring the integrity of the outer wall structure of the product and effectively cleaning large particles of impurities or dust on the outer wall.

[0039] like Figure 5 As shown, the cleaning device 3 at least includes a first spray head 31 that can be displaced relative to the flip device 2. The first spray head 31 is driven by a linear module 32 to move in a three-dimensional direction, and is driven by a rotary motor 33 to perform rotational spraying. The distal end of the first spray head 31 is provided with a first liquid outlet 311 and a second liquid outlet 312 at an angle; wherein the first liquid outlet 311 is located on the axis of the first spray head 31, and the second liquid outlet 312 is located on the outer wall of the first spray head 31, and the two are preferably arranged vertically. When the product is clamped by the upper clamp 41 and the side clamp 42 and driven to rotate by the flip frame 22, the high-pressure water sprayed from the first liquid outlet 311 and the second liquid outlet 312 performs all-round high-pressure cleaning on the product, effectively preventing the accumulation of impurities caused by sanitary dead corners on the product, and the cleaning is more comprehensive and thorough.

[0040] There are many implementation methods of the utility model, and all technical solutions formed by equivalent transformation or equivalent transformation fall within the protection scope of the utility model.
