Description

Technical Field

[0001] This utility model belongs to the field of automotive parts processing technology, and specifically relates to a surface treatment device for automotive parts processing. Background Technology

[0002] In the automotive manufacturing industry, the surface quality of parts directly affects product performance and lifespan, and surface treatment processes are a crucial link in ensuring quality. As a core pre-processing unit for surface treatment in automotive parts manufacturing, the surface oil cleaning device acts like a "cleaner" on the production line, undertaking a vital pre-treatment task. If oil or impurities remain on the surface of parts, subsequent surface treatment processes such as electroplating, painting, and coating will struggle to adhere firmly, leading to defects such as coating peeling and uneven coating, severely impacting the corrosion resistance, wear resistance, and aesthetics of the parts. Therefore, an efficient surface oil cleaning device is not only fundamental to ensuring the smooth operation of surface treatment processes but also a necessary prerequisite for improving the quality of automotive parts, extending product lifecycles, and enhancing overall vehicle reliability. It has profound significance for promoting the automotive manufacturing industry towards refinement and high quality.

[0003] Existing cleaning devices for automotive parts involve directly placing the parts to be cleaned into a cleaning net, suspending the net inside the cleaning chamber of the machine, and then using ultrasonic vibration to clean the oil stains on the surface of the automotive parts. However, if too many parts are stacked together, the ultrasonic energy may not be able to penetrate the gaps between the parts, and the oil stains and debris at the contact points may not be effectively impacted, creating a "cleaning blind spot". If only one layer of parts is placed, the number of parts that can be cleaned at one time is small, resulting in low cleaning efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a surface treatment device for automotive parts processing, aiming to solve the problem that existing cleaning devices for automotive parts, in the process of cleaning automotive parts, directly put the parts to be cleaned into a cleaning net bag, and then suspend the net bag in the cleaning chamber of the cleaning machine, and use the principle of ultrasonic vibration to clean the oil stains on the surface of the automotive parts, can easily cause the ultrasonic energy to be unable to penetrate the gaps between the parts, and the oil stains and debris at the contact points are difficult to be effectively impacted, forming a "cleaning blind zone". If a layer of parts is placed, the number of parts to be cleaned at one time is small, resulting in low parts cleaning efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a surface treatment device for processing automotive parts, comprising a cleaning machine body, a control panel connected to the front surface of the cleaning machine body, a placement groove formed on the upper surface of the inner wall of the cleaning machine body, a cleaning mesh frame inserted into the surface of the placement groove, a limiting groove formed on the top surface of the cleaning mesh frame, a first limiting block slidably connected to the surface of the limiting groove, a bottom mesh frame connected to the other side surface of the first limiting block, a screw connected to the top surface of the bottom mesh frame, a support tube threadedly connected to the surface of the screw, a partition mesh frame abutting the top surface of the support tube, a screw inserted into the surface of the partition mesh frame, a second limiting block connected to the surface of the partition mesh frame, and the second limiting block slidably connected to the surface of the limiting groove.

[0006] In a preferred embodiment of the surface treatment device for processing automotive parts according to this utility model, the limiting groove, the first limiting block, and the bottom mesh frame form a sliding connection structure, and the limiting groove, the partition mesh frame, and the second limiting block form a sliding connection structure.

[0007] As a preferred embodiment of the surface treatment device for processing automotive parts according to this utility model, the inner wall of the support tube is provided with a threaded groove, and the shape and size of the threaded groove are adapted to the thread on the surface of the screw.

[0008] As a preferred embodiment of the surface treatment device for processing automotive parts according to this utility model, circular through grooves are respectively opened on both sides of the longitudinal end of the partition frame, and the shape and size of the through grooves are adapted to the screw.

[0009] As a preferred embodiment of the surface treatment device for automotive parts processing according to this utility model, the front end of the cleaning machine body is connected to a fixed frame on the side surface next to the control panel. A moving groove is opened on the inner wall surface of the fixed frame, and a spring is connected to the inner wall surface of the fixed frame. The other side surface of the spring is connected to the surface of the connecting block.

[0010] In a preferred embodiment of the surface treatment device for processing automotive parts according to this utility model, the surface of the connecting block is movably sleeved on the surface of the limiting rod, the other side surface of the limiting rod is connected to the inner wall of the fixing frame, the surface of the connecting block is connected to the surface of the protective plate, and the protective plate is movably connected to the inner wall of the fixing frame.

[0011] In a preferred embodiment of the surface treatment device for processing automotive parts according to this utility model, the fixing frame, spring, connecting block and protective plate form an elastic connection structure.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] By cooperating with the cleaning mesh frame, limiting groove, first limiting block, bottom mesh frame, screw, support tube, partition mesh frame and second limiting block, the partition mesh frame of the appropriate size is selected according to the size of the automotive parts to be cleaned. The partition mesh frame is fixed by the limiting groove opened on the cleaning mesh frame and the screw and the support tube connected to it by threads. Multiple partition mesh frames can be fixed in the cleaning mesh frame according to the size of the parts, so that multiple layers of parts can be placed in the cleaning chamber of the cleaning machine body at one time, thereby improving cleaning efficiency while ensuring cleaning quality.

This prevents the sewage generated during the cleaning process from adhering to the buttons on the surface of the control panel. After the sewage dries, it may form sticky residues, which may affect the sensitivity of the buttons. Attached Figure Description

Detailed Implementation

[0021] 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.

[0022] Please see Figures 1-4 This utility model provides the following technical solution: a surface treatment device for processing automotive parts, including a cleaning machine body 1, a control panel 2 connected to the front surface of the cleaning machine body 1, a placement groove 3 opened on the upper surface of the inner wall of the cleaning machine body 1, a cleaning mesh frame 4 inserted into the surface of the placement groove 3, a limiting groove 5 opened on the top surface of the cleaning mesh frame 4, a first limiting block 6 slidably connected to the surface of the limiting groove 5, a bottom mesh frame 7 connected to the other side surface of the first limiting block 6, a screw 8 connected to the top surface of the bottom mesh frame 7, a support tube 9 threadedly connected to the surface of the screw 8, a separating mesh frame 10 abutting the top surface of the support tube 9, a screw 8 inserted into the surface of the separating mesh frame 10, a second limiting block 11 connected to the surface of the separating mesh frame 10, and a second limiting block 11 slidably connected to the surface of the limiting groove 5. In this design, the cleaning machine body 1, control panel 2, placement groove 3 and cleaning mesh frame 4 constitute the main body of an ultrasonic cleaning machine, and a large number of related components are set in the main body of the ultrasonic cleaning machine. Since these are existing technologies and the core content of this technical solution is irrelevant to them, they will not be described in detail in this technical solution.

[0023] The main model of the ultrasonic cleaner in this solution is: jp-240plus0-1800w.

[0024] In operation: When the ultrasonic cleaner cleans automotive parts, the ultrasonic generator converts the main power frequency energy into a high-frequency electrical signal of 20-40kHz, which is transmitted to the transducer via a high-frequency cable. The transducer, receiving a high-frequency voltage, generates ultrasonic vibrations that propagate through the liquid in the cleaning tank. Numerous tiny bubbles are generated in the liquid; these bubbles rapidly expand and burst under the action of the ultrasonic waves, creating a cavitation effect. The instantaneous bursting of these bubbles generates a powerful impact force and localized high temperature and pressure, much like countless tiny brushes impacting the inner and outer walls of the automotive parts placed within the cleaning mesh frame 4. This dislodges micron-sized oil, carbon deposits, dust, and other contaminants from the surface of the parts, dissolving or dispersing them in the cleaning solution, thus achieving the cleaning purpose.

[0025] Preferably, the limiting groove 5, the first limiting block 6 and the bottom grid frame 7 form a sliding connection structure, and the limiting groove 5, the partition grid frame 10 and the second limiting block 11 form a sliding connection structure.

[0026] In practical use, the limiting groove 5 opened at the top of the cleaning mesh frame 4 is used to slide and insert the first limiting blocks 6 on both sides of the bottom mesh frame 7, thereby fixing the position of the bottom mesh frame 7 inside the cleaning mesh frame 4. At the same time, the second limiting block 11 connected to the surface of the separating mesh frame 10 can also be conveniently connected to the position of the separating mesh frame 10 inside the cleaning mesh frame 4.

[0027] Preferably, the inner wall of the support tube 9 is provided with a threaded groove, and the shape and size of the threaded groove are adapted to the surface thread of the screw 8.

[0028] In practical use, according to the height of the components placed inside the bottom frame 7, the support tube 9 is threaded onto the screw rod 8. Thus, by using the support tubes 9 with parallel heights on both sides, the partition frame 10 can be inserted into the screw rod 8 and the position of the partition frame 10 is supported and fixed by the support tubes 9 threaded onto the screw rod 8.

[0029] Preferably, circular through slots are provided on both sides of the longitudinal end of the partition frame 10, and the shape and size of the through slots are adapted to the screw 8.

[0030] In practical use, the circular through groove on the surface of the partition frame 10 allows the screw 8 to be inserted into it, and the support tube 9 connected to the screw 8 supports the partition frame 10.

[0031] Preferably, the front end of the cleaning machine body 1 is connected to the fixing frame 12 on the side surface next to the control panel 2. The inner wall surface of the fixing frame 12 has a moving groove 13. The inner wall surface of the fixing frame 12 is connected to the spring 14. The other side surface of the spring 14 is connected to the surface of the connecting block 15.

[0032] In actual use, the connecting block 15 slides on the limiting rod 16, limiting the movement range of the protective plate 17, thereby causing the protective plate 17 to move again and block the front end of the control panel 2.

[0033] Preferably, the surface of the connecting block 15 is movably sleeved on the surface of the limiting rod 16, the other side surface of the limiting rod 16 is connected to the inner wall of the fixing frame 12, the surface of the connecting block 15 is connected to the surface of the protective plate 17, and the protective plate 17 is movably connected to the inner wall of the fixing frame 12.

[0034] In actual use, releasing the hand holding the protective plate 17 will cause the protective plate 17 to rebound towards the fixed frame 12 via the spring 14 connected to the surface of the connecting blocks 15 on both sides. At the same time, the connecting blocks 15 slide on the limit rod 16, thereby limiting the movement range of the connecting blocks 15.

[0035] Preferably, the fixing frame 12, spring 14, connecting block 15 and protective plate 17 form an elastic connection structure.

[0036] In practical use, the spring 14 connecting the fixed frame 12 and the connecting block 15 is used to make the connecting block 15 drive the protective plate 17 to move elastically on the fixed frame 12, thereby fixing the position of the protective plate 17 on the fixed frame 12.

[0037] Working principle: In the automotive parts production process, the oil stains adhering to the surface of parts that need to be electroplated or painted are cleaned to facilitate subsequent processing. A partition frame 10 of appropriate size is selected based on the size of the parts to be cleaned. The parts to be cleaned are then laid sequentially on the bottom of the cleaning frame 4, and inside the selected base frame 7 and partition frame 10. The limiting groove 5 at the top of the cleaning frame 4 is used to slide and insert the first limiting blocks 6 on both sides of the base frame 7, thereby fixing the position of the base frame 7 inside the cleaning frame 4. Then, according to the height of the parts placed inside the base frame 7, the support rod 9 is threaded onto the screw 8. The parallel height of the support rods 9 on both sides ensures that the partition frame 10... It can be inserted into the screw 8, so that the bottom of the partition frame 10 is supported by the support tube 9 threaded to the screw 8, thereby fixing the position of the partition frame 10 on the screw 8. Then, according to the remaining space on the inner wall of the cleaning frame 4, the partition frame 10 of the corresponding size is selected and fixed to the surface of the screw 8 again by the support tube 9 threaded to it. This makes good use of the space inside the cleaning frame 4, and cleans the parts on the partition frame 10 placed in multiple layers at one time. This improves cleaning efficiency while ensuring cleaning quality and avoids stacking too many parts, which would create dead corners. Then, the placement slots 3 on both sides of the cleaning frame 4 are inserted and overlapped on the placement slots 3, thereby using gravity to fix the position of the cleaning frame 4 in the cleaning chamber inside the cleaning machine body 1.

[0038] At this point, after placing the parts to be cleaned, pull the protective plate 17 in the opposite direction of the fixing frame 12 to expose the control panel 2, which is covered by the protective plate. This allows the user to easily operate the buttons on the surface of the control panel 2 to clean the parts placed inside the cleaning machine body 1. After the operation is completed, release the hand holding the protective plate 17, and the protective plate 17 will be driven by the spring 14 connected to the surface of the connecting blocks 15 on both sides to rebound towards the fixing frame 12. At the same time, the connecting blocks 15 slide on the limit rod 16, limiting the range of movement of the protective plate 17. This allows the protective plate 17 to move again to cover the front end of the control panel 2, preventing the wastewater carried when the parts are picked up from adhering to the buttons on the surface of the control panel 2. This would prevent the dried and sticky substances from affecting the sensitivity of the buttons on the control panel 2.

[0039] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
