Description

Technical Field

[0001] This utility model relates to the technical field of passivation devices for indium steel parts, and in particular to a special passivation device for the surface of indium steel parts. Background Technology

[0002] In the surface treatment of indium steel parts, traditional passivation methods typically require cleaning the surface first, followed by passivation. These two steps are usually performed separately, resulting in long processing times, low efficiency, and the potential introduction of new contaminants during the transition between cleaning and passivation, which can negatively impact the passivation effect.

[0003] A search revealed that patent number "CN220432974U" provides a passivation device for mechanical manufacturing, applicable to the field of parts passivation technology. The device includes a frame and a passivation cylinder mounted on the frame. A lifting platform is movably mounted within the frame via a telescopic cylinder. A support base is fixedly mounted on the bottom surface of the lifting platform via a support rod. A holding basket is mounted on the support base, which also includes a drive mechanism for shaking the basket. This drive mechanism, by causing the basket to shake at multiple angles, can cause multiple parts placed inside the basket to shake. During the passivation process, the shaking of the basket increases the flow of the passivation liquid. The mobility of the container accelerates the passivation efficiency of the parts to a certain extent. After the telescopic cylinder drives the container to detach from the passivation liquid, the shaking of the container can throw out the passivation liquid accumulated on the surface or internal grooves of the parts. The thrown-out passivation liquid can fall back into the passivation cylinder, avoiding waste of resources. During use, the drive mechanism drives the container to shake at multiple angles, which accelerates the passivation efficiency of the parts. At the same time, the thrown-out passivation liquid falls into the passivation cylinder for collection again, avoiding waste of passivation liquid. However, before the parts are passivated, the surface dirt and rust need to be cleaned. After cleaning, new pollution will be generated during transportation, which will affect the formation effect of the subsequent passivation film.

[0004] Therefore, we provide a special passivation device for the surface of indium steel parts to solve the above problems. Utility Model Content

[0027] Please see Figure 1-8 This utility model provides a technical solution: a special passivation device for the surface of indium steel parts, including a housing 1 and a functional mechanism 7. A mesh frame 2 is provided on the inner side of the housing 1, and a lifting frame 3 is installed on the top of the housing 1. A lifting motor 4 is bolted to the top of one side of the lifting frame 3, and an operating plate 5 is screwed to the outer side of the other side of the lifting frame 3. A lifting slide 6 is provided on the inner side of the lifting frame 3. The functional mechanism 7 includes a moving component 71, a connecting component 72, a brushing component 73, and a measuring component 74. The moving component 71 is slidably connected to the inner side of the lifting slide 6. The connecting component 72 is bolted to the bottom of the moving component 71. The brushing component 73 is bolted to the bottom of the connecting component 72. The measuring component 74 is provided inside the brushing component 73. Two liquid channels are provided at the rear end of the housing 1, which are used for the recovery of passivation liquid and the collection of waste liquid after cleaning, respectively.

[0028] Furthermore, the moving component 71 includes a horizontal frame 711, a horizontal motor 712, a horizontal slide 713, and a sliding frame 714. The horizontal frame 711 is slidably connected to the inner side of the lifting slide 6. The horizontal frame 711 is connected to the lifting motor 4 via a hinge. The horizontal motor 712 controls the horizontal movement of the sliding frame 714 within the horizontal slide 713 via a hinge.

[0029] Furthermore, a horizontal motor 712 is bolted to the top of the horizontal frame 711, and a horizontal groove 713 is formed at the bottom of the horizontal frame 711. A sliding frame 714 is slidably connected to the inner side of the horizontal groove 713. The horizontal groove 713 fixes the sliding frame 714. The sliding frame 714 is connected to the horizontal motor 712 through a hinge. When the horizontal motor 712 rotates, it drives the hinge to move, thereby causing the hinge to move the sliding frame 714.

[0030] Furthermore, the connecting assembly 72 includes a buffer frame 721, a connecting plate 722, a connecting frame 723, a connecting water pipe 724, a plastic water pipe 725, and a nozzle 726. The bottom end of the sliding frame 714 is bolted to the buffer frame 721, and the bottom end of the buffer frame 721 is bolted to the connecting plate 722. The outer sides of the connecting plate 722 are all bolted to the connecting frame 723, and the outer sides of the connecting frame 723 are all provided with connecting water pipes 724. The outer sides of the connecting water pipes 724 are provided with plastic water pipes 725, and the ends of the plastic water pipes 725 are all threaded. The nozzle 726 is included. The buffer frame 721 has a rectangular telescopic tube exterior and is equipped with a stepper motor and slide rail inside. The stepper motor has high precision, high resolution and good dynamic response capability, which can achieve fine adjustment of position. The displacement of the connecting plate 722 can be further fine-tuned through the stepper motor and slide rail to adapt to the fine adjustment of the pressure between the brush blob 735 and the surface of the part. The plastic water pipe 725 is existing technology. The shape of the plastic water pipe 725 can be adjusted by the operator, which makes it convenient for the operator to adjust the position of the nozzle 726.

[0031] Furthermore, the brushing assembly 73 includes a mounting ring 731, a rotary motor 732, a mounting plate 733, a brush plate 734, and a bristle bundle 735. The mounting ring 731 is bolted to the bottom end of the connecting bracket 723. The rotary motor 732 is fixedly connected to the bottom end of the mounting ring 731. The rotor of the rotary motor 732 passes through the mounting plate 733. The mounting plate 733 is disposed on the outer shell of one side of the rotor of the rotary motor 732. The brush plate 734 is fixedly connected to the outer side of the rotor at one end of the rotary motor 732. The bottom end of the brush plate 734 is provided with a bristle bundle 735. The bristle bundle 735 is made of soft bristles of nylon or soft plastic with moderate density. Under the lubrication of the passivation fluid... The brush can effectively remove dirt, rust, and impurities from the surface of parts. At the same time, spraying passivating liquid can immediately form a passivation film on the cleaned surface, improving the passivation effect. The rotor of the rotary motor 732 is fixedly connected to the brush plate 734. When the rotary motor 732 rotates, it can drive the brush plate 734 to rotate, so that the brush bristles 735 clean the inside and outside of the parts. The mounting plate 733 is fixed on the outer shell of one end of the extended rotor of the rotary motor 732 and is rotatably connected to the brush plate 734. This can prevent the rotor of the rotary motor 732 from shifting under the action of external force due to the brush plate 734 during operation, thereby reducing the service life of the rotary motor 732.

[0032] Furthermore, the measuring component 74 includes a brush cluster 741, a locking block 742, a mounting rod 743, a displacement block 744, and a pressure sensor 745. The brush tuft 735 contains a specially designed brush cluster 741 and ordinary bristles for brushing. A locking block 742 is located at the top of the brush cluster 741, and the mounting rod 743 is fixedly connected to the top of the locking block 742. The displacement block 744 is sleeved on the outside of the mounting rod 743, and the pressure sensor 745 contacts the outside of the displacement block 744. When the brush plate 734 rotates, it drives the brush cluster 741 to rotate. The brush cluster 741 partially contacts the surface of the part. After the surfaces are bonded, the rotation of the brush cluster 741 will generate a pushing force on the locking block 742 and the mounting rod 743, causing the mounting rod 743 to shift. The shift of the mounting rod 743 will also cause the displacement block 744 to shift, thereby causing the displacement block 744 to squeeze the pressure sensor 745, which in turn makes the pressure sensor 745 sense the pressure and complete the detection. This enables the device to detect the pressure between the brush cluster 735 and the surface of the part. The brush cluster 735 is provided with multiple sets of brush clusters 741, and the bristle material used in the brush cluster 741 is the same as the bristle material of the brush cluster 735.

[0033] Furthermore, the bottom end of the brush plate 734 is provided with a hole for inserting the mounting rod 743, and a pressure sensor 745 is installed in the hole. The pressure sensor 745 is a thin-film pressure sensor and corresponds to the position of the displacement block 744. The mounting rod 743 is inserted into the reserved mounting hole of the brush plate 734, and the pressure sensor 745 is aligned with the position of the displacement block 744 to complete the installation of the brush cluster 741. Multiple sets of brush clusters 741 can be set. By analyzing the pressure change curves of multiple sets of pressure sensors 745, the pressure between the brush cluster 735 and the surface of the part can be obtained. Then, the height of the brush plate 734 can be adjusted by the lifting motor 4. At the same time, without starting the rotary motor 732, the pressure between the brush cluster 735 and the part can also be detected by the displacement block 744 caused by the contact between the brush cluster 741 and the part by the pressure sensor 745.

[0034] Working principle: First, the special passivation device for the surface of the indium steel parts is moved to the working position. Firstly, the passivation liquid is connected to the connection point of the water pipe 724 via a pipe. Secondly, the parts to be passivated are placed in the mesh frame 2. The horizontal motor 4 is adjusted via the operating panel 5. The horizontal motor 4 drives the horizontal frame 711 to adjust its vertical displacement within the lifting slide 6 via a hinge. Thirdly, when the horizontal frame 711 descends, it drives the brush plate 734 to descend, causing the brush bristles 735 to contact the parts. Because the brush bristles 735... When the brush cluster 741 comes into contact with the surface of the part, the base of the brush bristles shifts position. For the brush cluster 741, this causes the locking block 742 to shift position. The shift in the position of the locking block 742 causes a relative shift in the position of the displacement block 744, which in turn squeezes the pressure sensor 745. Thus, the pressure sensor 745 indirectly obtains the pressure status when the brush cluster 741 and brush ball 735 come into contact with the part. In the fourth step, the operator reads the pressure status at the operation panel 5 and simultaneously through the buffer frame 72. Step 5 involves fine-tuning the pressure between the brush blob 735 and the part surface. The fifth step involves starting the rotary motor 732, which drives the brush blob 735 and brush cluster 741 to rotate, cleaning the part surface. Simultaneously, the passivation liquid sprayed from the nozzle 726 is immediately applied to the part surface, allowing for immediate application of passivation liquid after cleaning, thus improving the passivation film formation effect. The brush blob 735 can completely clean light to moderate stains on the part surface after 2-5 minutes of operation. For heavy stains... The parts need to be cleaned in advance. After the brush 735 is cleaned, the operation stops and the spray nozzle 726 continues to spray passivating liquid for passivation. During this period, the horizontal motor 712 drives the brush 735 to make horizontal displacement to ensure that the passivation film on the surface of the parts is formed evenly. In the sixth step, during the cleaning operation, the passivating liquid concentrated in the box 1 flows into the filter device from the liquid channel at the rear of the box 1 and can then be connected to the water pipe 724 for reuse. This completes the process of using the special passivation device for the surface of indium steel parts.
