Abstract
Description
Technical Field
[0001] This utility model relates to the field of vacuum coating fixture technology, and in particular to vacuum coating fixtures for metal parts. Background Technology
[0002] Metal fittings are components made from metal materials through casting, forging, cutting, and stamping processes, and are customized according to specific needs. With their high strength, good electrical conductivity, thermal conductivity, and corrosion resistance, they play a crucial role in machinery manufacturing, automotive, aerospace, and electronics industries. They are essential basic components ensuring the normal operation of equipment and achieving structural connections and functional operation. Vacuum coating fixtures for metal fittings are specialized devices used to fix, support, and position metal fittings in the vacuum coating process. Made from high-temperature resistant, corrosion-resistant metal materials with good mechanical strength, they are important tools for ensuring the quality of vacuum coating and production efficiency of metal fittings.
[0003] Existing fixtures use permanent magnets mounted on the fixture to attract and fix metal parts using the magnetic field generated by the permanent magnets. However, when attracting metal parts that are too large, the permanent magnets cannot provide sufficient magnetism, thus the metal parts cannot be firmly secured. Existing technologies increase the number of permanent magnets to attract metal parts that are too large. However, the distribution of permanent magnets is regular and it is difficult to completely conform to the surface of irregularly shaped parts. This can easily lead to uneven attraction forces, causing the parts to shake or shift during the attraction process. This seriously affects the coating quality of the metal parts and increases the coating cost. Utility Model Content

[0031] 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.
[0032] Reference Figure 1 , Figure 3 and Figure 5This utility model provides an embodiment of a vacuum coating fixture for metal parts, comprising a vacuum cabinet 1. A groove 25 is formed in the middle of the bottom of the inner wall of the vacuum cabinet 1. Slider blocks 15 are slidably connected to both the left and right ends of the groove 25, allowing the sliders 15 to slide within the groove 25. A fixing post 16 is fixedly connected to the top of the slider 15. A three-way pipe 17 is fixedly connected to the middle of the outer wall of the fixing post 16. A turntable 18 is rotatably connected to the left end of the inner wall of the three-way pipe 17. When the slider 15 slides within the groove 25, the turntable 18 moves synchronously left and right within the groove 25. Multiple springs 19 are fixedly connected at equal intervals to the outer side of the turntable 18. A support rod 21 is fixedly connected to the middle of the outer side of the turntable 18. Multiple fixing blocks 22 are fixedly connected at equal intervals to the outer side of the support rod 21. Multiple adjusting rods 20 are fixedly connected to the top of the fixing blocks 22. The bottom of the fixing blocks 22 is connected to the adjusting rods... The adjustment rod 20 is slidably connected to the fixed block 22 by the spring 19. The top of the adjustment rod 20 is rotatably connected to the shaft 23, and the top of the adjustment rod 20 is rotatably connected to the claw 24 through the shaft 23. Therefore, the claw 24 will move synchronously with the turntable 18. When the claw 24 is released, the clamp will hold the metal parts under the elastic contraction of the spring 19. The bottom left and right sides of the inner wall of the vacuum cabinet 1 are fixedly connected to the cleaning mechanism 2, which is used to clean the waste on the left and right sides of the inner wall of the vacuum cabinet 1. The lower middle part of the vacuum cabinet 1 is slidably connected to the storage box 3. The front side of the outer wall of the storage box 3 is fixedly connected to the ball pull block 4, which is convenient for users to store items. The four corners of the bottom of the vacuum cabinet 1 are fixedly connected to the load-bearing column 5. The bottom of the load-bearing column 5 is fixedly connected to the foot pad 6 to reduce the impact of the device on the ground.
[0033] Specifically, the slider 15 can slide left and right on the groove 25. A fixed post 16 is installed on the slider 15, and a three-way pipe 17 is welded to the middle of the fixed post 16. The turntable 18 can be fixed to the fixed post 16 through the three-way pipe 17. The turntable 18 can rotate at the left end of the three-way pipe 17 to achieve a flipping effect. A support rod 21 is welded to the left side of the turntable 18. Springs 19 are installed at equal intervals around the left side of the turntable 18, and an adjusting rod 20 is welded to the left side of the springs 19. Therefore, the springs 19 can pull the adjusting rods 20 according to their own elasticity. Because fixed blocks 22 are welded at equal intervals around the left end of the support rod 21, and two adjusting rods 20 are installed on the top of the fixed blocks 22, the claw 24 can be relatively fixed and rotated with the fixed blocks 22 through the rotating shaft 23 on the adjusting rods 20. The adjusting rod 20 on the left side of the spring 19 is connected to another adjusting rod. The adjustment rod 20 can slide inside the fixed block 22 by rotating the pivot 23, so the elasticity of the spring 19 can drive the claw 24 to rotate around the fixed block 22, achieving the effect of clamping and fixing. This solves the problem of the accessories shaking or shifting during the adsorption process, which seriously affects the coating quality of the metal accessories and increases the coating cost. A sliding storage box 3 is set in the middle and lower part of the vacuum cabinet 1. A spherical pull block 4 is firmly embedded on the front outer wall of the storage box 3. The rounded shape conforms to the ergonomic design, making it easy for users to lift and open and close, providing convenient storage space for storing various items. At the four corners of the bottom of the vacuum cabinet 1, load-bearing columns 5 are vertically fixed. The bottom of each load-bearing column 5 is equipped with a special foot pad 6, which is made of elastic cushioning material, which can effectively disperse pressure and significantly reduce the impact force on the ground when the device is running.
[0034] Reference Figure 1 , Figure 2 and Figure 6 The cleaning mechanism 2 includes a limiting plate 201. A drive shaft 203 is rotatably connected to the upper middle part of the limiting plate 201. A retaining ring 208 is fixedly connected to the right outer end of the drive shaft 203 to limit its position. A rotating ring 205 is fixedly connected to the right middle part of the outer wall of the drive shaft 203. A brush 206 is fixedly connected to the outer wall of the rotating ring 205. The brush 206 can clean the inner wall of the vacuum cabinet 1. A sealing sleeve 204 is fixedly connected to the middle outer part of the drive shaft 203 to seal the vacuum cabinet 1. The left outer part of the drive shaft 203... A turntable 202 is fixedly connected to the end, and a rotating handle 207 is fixedly connected to the left side of the outer wall of the turntable 202. Therefore, the brush 206 will rotate synchronously with the turntable 202 driven by the rotating handle 207. A sealing ring 7 is fixedly connected to the front side of the upper middle part of the vacuum cabinet 1. A transparent cabinet door 8 is fixedly connected inside the sealing ring 7, which facilitates the handling of metal parts while maintaining the vacuum inside the cabinet. Multiple welding blocks 10 are fixedly connected to the right side of the front middle part of the transparent cabinet door 8. An arc-shaped handle 9 is fixedly connected to the front side of the welding block 10, which facilitates the observation of the coating condition inside the cabinet.
[0035] Specifically, the rotary handle 207 is installed on the left end of the turntable 202, and its right end is welded to the drive shaft 203. A rotating ring 205 is welded to the right side of the center of the drive shaft 203, and the outer side of the rotating ring 205 is welded to the brush 206 for cleaning the inner wall of the vacuum cabinet 1. A sealing sleeve 204 is installed in the center of the drive shaft 203 to ensure continuous vacuum inside the vacuum cabinet 1 during cleaning. A limiting plate 201 is installed on the right side of the drive shaft 203 to stabilize the cleaning mechanism 2. A retaining ring 208 is installed at the right end of the drive shaft 203 to prevent it from moving left or right during rotation. Therefore, when the rotary handle 207 is rotated, it synchronously drives the brush 206 to rotate, solving the problem of not being able to clean the inner wall of the vacuum cabinet 1 in time during coating, thus affecting its vacuum performance. The upper front side of the vacuum cabinet 1... A tightly fixed annular sealing ring 7 is fitted inside a transparent cabinet door 8. The sealing ring 7 is made of highly elastic silicone material, which can form a tight seal with the cabinet door, ensuring that the vacuum environment inside the cabinet is not disturbed by the outside world. The transparent cabinet door 8 not only allows operators to directly observe the condition of the internal metal parts, but also facilitates quick access and placement. While ensuring ease of operation, it effectively maintains the sealing and functionality of the vacuum cabinet 1. Multiple welding blocks 10 are evenly distributed and firmly welded to the right side of the front center of the transparent cabinet door 8. Each welding block 10 extends a smooth arc-shaped handle 9 from its front end. This design not only conforms to human grip habits and makes it easy to open and close the cabinet door, but also allows the operator to stand naturally and observe the real-time progress and detailed changes of the coating of the metal parts inside the cabinet without obstruction when the cabinet door is closed.
[0036] Reference Figure 2 and Figure 3 A limit ring 11 is fixedly connected to the upper right side of the vacuum cabinet 1. A magnetic block 12 is fixedly connected to the inner side of the limit ring 11 for temporary storage of small metal parts. Multiple screws 14 are threadedly connected to the lower left side of the vacuum cabinet 1. A warning sign 13 is threadedly connected to the outer side of the screws 14 for warning purposes.
[0037] Specifically, on the upper right side of vacuum cabinet 1, a ring-shaped limiting ring 11 is precisely fixed, with a high-performance magnetic block 12 tightly fitted inside. This magnetic block 12 is made of rare-earth permanent magnet material, which can generate a stable and strong adsorption force, quickly adsorbing small metal parts. This not only prevents parts from being scattered and lost, but also provides operators with a convenient temporary storage space during the coating operation, significantly improving work efficiency. On the lower left side of vacuum cabinet 1, multiple screw holes are set at equal intervals, and screws 14 are tightly connected to them through a precise thread engagement. On the outside of the screws 14, warning signs 13 are securely installed with the same thread connection, which plays a significant role in warning of potential dangers and operating precautions, ensuring the safe use of the equipment.
[0038] Working principle: By sliding the slider 15 and actuating the jaws 24, the clamp can stably hold any type of metal part. The slider 15 can slide left and right on the groove 25. A fixing post 16 is mounted on the slider 15, and a T-shaped pipe 17 is welded to the middle of the fixing post 16. The turntable 18 can be fixed to the fixing post 16 through the T-shaped pipe 17. The turntable 18 can rotate at the left end of the T-shaped pipe 17, thus achieving a flipping effect. A support rod 21 is welded to the left side of the turntable 18. Springs 19 are equidistantly installed around the left side of the turntable 18, and an adjusting rod 20 is welded to the left side of each spring 19. Therefore, the springs 19 can adjust according to their own elasticity. The spring 19 pulls the adjusting rod 20. Because the left end of the support rod 21 is welded with fixed blocks 22 at equal intervals, and two adjusting rods 20 are installed on the top of the fixed blocks 22, the claw 24 can rotate relative to the fixed blocks 22 through the rotating shaft 23 on the adjusting rod 20. The adjusting rod 20 on the left side of the spring 19 rotates with another adjusting rod 20 through the rotating shaft 23 and the adjusting rod 20 can slide inside the fixed block 22. Therefore, the elasticity of the spring 19 can drive the claw 24 to rotate around the fixed block 22, achieving the clamping and fixing effect. This solves the problem of the accessories shaking or shifting during the adsorption process, which seriously affects the coating quality of metal accessories and increases the coating cost.
[0039] The inner wall of the vacuum cabinet 1 is cleaned by rotating the rotary handle 207. The rotary handle 207 is installed on the left end of the turntable 202, and its right end is welded to the drive shaft 203. A rotating ring 205 is welded to the right side of the middle of the drive shaft 203, and the outer side of the rotating ring 205 is welded to the brush 206 to clean the inner wall of the vacuum cabinet 1. A sealing sleeve 204 is installed in the middle of the drive shaft 203 to ensure that the vacuum cabinet 1 is kept in a continuous vacuum during cleaning. A limiting plate 201 is installed on the right side of the drive shaft 203 to stabilize the cleaning mechanism 2. A retaining ring 208 is installed on the right end of the drive shaft 203 to prevent the drive shaft 203 from moving left and right when rotating. Therefore, when the rotary handle 207 is rotated, it will drive the brush 206 to rotate synchronously, which solves the problem that the inner wall of the vacuum cabinet 1 cannot be cleaned in time when coating is performed inside the vacuum cabinet 1, thus affecting its vacuum performance.
