Description

Technical Field

[0001] The present invention relates to the technical field of chassis grinding, and particularly relates to a grinding device for computer chassis processing. Background Art

[0002] The manufacturing process of computer chassis usually includes multiple steps such as welding and grinding of plates. The main process is as follows: Plate blanking: Cut the metal plates (usually cold-rolled steel plates or aluminum plates) according to the design drawings. The cutting methods can include laser cutting, numerical control punching or shearing, etc. Stamping and bending: Process the metal plates into different shapes and structures of the chassis through stamping and bending processes, such as side panels, top covers, brackets, etc. This step can form the basic contour of the chassis as well as heat dissipation holes, mounting hole positions, etc. Welding: Assemble and weld the processed plates together to form the basic framework of the chassis. Select an appropriate welding process according to the material and precision requirements. The purpose of welding is to ensure the structural strength and stability of the chassis. Grinding: After welding, the metal surface will leave welding points, weld seams and splashed metal particles, which need to be ground and polished to eliminate welding marks and make the chassis surface smooth and shiny. Grinding can also remove sharp corners and improve safety. Usually, further polishing is carried out after grinding to enhance the appearance. Surface treatment: After grinding, surface treatment is carried out, such as spraying, electroplating or oxidation treatment, to enhance the corrosion resistance and aesthetics of the chassis. Steel chassis are usually sprayed with coatings, while aluminum chassis may use anodic oxidation treatment to increase surface hardness and protective performance. Assembly and inspection: Assemble various components onto the chassis main body, and finally conduct quality inspection to ensure that dimensions, strength, aesthetics, etc. meet the standards.

[0003] Through processes such as welding, grinding, and surface treatment, metal computer chassis can have characteristics such as firm structure, durability, corrosion resistance, and beautiful appearance. In the processing of computer chassis, grinding the corners is a key process, and the main reasons include the following: Improving safety: The unground corners may have sharp burrs or sharp corners, which are likely to cause cuts to assembly workers or users. Grinding can remove burrs and make the corners smooth, reducing the risk of accidental injury. Improving the appearance quality: After the chassis is ground, the corners appear smoother and the overall appearance is more beautiful. The smooth edges can make the product look more textured and enhance the user's first impression. Facilitating subsequent processing (such as spraying or electroplating): The chassis often needs to undergo surface treatment processes such as painting and electroplating. The unground corners may affect the adhesion of the coating, resulting in uneven coating thickness or even peeling at the edges, thus affecting the quality and durability of the product. Improving the assembly accuracy: Grinding can ensure that the corners are flat, reduce dimensional errors, facilitate the precise alignment of each component, and improve the stability and efficiency of the assembly process.

[0004] Therefore, grinding is an important step in processing to improve the quality, appearance, safety, and assembly efficiency of the computer case. In existing grinding devices, if manual fixation of the computer case is required and then combined with a grinding machine for grinding, the following hazards may occur: Risk of worker injury: Manually fixing the computer case and operating the grinding machine can easily expose workers to the high-speed rotating parts of the grinding machine. Especially during the grinding process of the corners of the computer case, workers may be scratched or cut by sharp metal edges or flying debris generated during grinding. Hazard of dust inhalation: A large amount of metal dust is generated during the operation of the grinding machine. These tiny particles spread in the air and are easily inhaled by workers. Long-term inhalation of metal dust may cause respiratory diseases such as pneumoconiosis and chronic bronchitis. Muscle strain and fatigue: Workers need to manually fix and operate the equipment, and repeated similar actions for a long time can easily cause muscle strain and fatigue in the arms, wrists, and shoulders, and may even lead to work-related injuries such as tendinitis and muscle strains. Operational instability: Manually fixing the computer case may not be stable enough, easily resulting in uneven grinding or misoperation due to sliding. If the equipment generates a reaction force, it may be difficult for workers to maintain stability, leading to over-grinding or under-grinding and affecting product quality. Risk of burns from sparks or flying debris: Sparks or flying metal chips may be generated during the grinding process. When workers do not wear sufficient protective equipment, their skin and eyes are easily burned or stabbed.

[0005] In view of the above situation, in order to overcome the above technical problems, the present invention designs a grinding device for computer case processing, which solves the above technical problems. Summary of the Invention

[0006] The technical objective to be achieved by the present invention is: to design a grinding device for computer case processing, where only the computer case needs to be placed in the processing mechanism, and the corresponding fixing mechanism, clamping mechanism, and pushing component can move in sequence to achieve the clamping and fixing effect on the computer case, eliminating the many inconveniences of manual fixation and also improving the general adaptability of grinding each corner of the computer case.

[0007] In order to achieve the above technical objective, the present invention provides the following technical solutions:

[0008] A grinding device for computer case processing aims to achieve automated grinding treatment of the corners of the computer case, improve processing efficiency, and reduce the risk of manual operation. The device includes a bracket, a processing mechanism, a driving cylinder, a pushing component, a clamping mechanism, a fixing mechanism, a moving base, and a grinding machine. Each component cooperates closely to jointly complete the precise fixation and corner grinding of the computer case.

[0009] Among them, the bracket is the basic framework of the entire device, used to support and fix each processing component, providing a stable working platform. Above the bracket is installed a processing mechanism, which is a key device for accommodating the chassis and has positioning and fixing functions. The structural design of the processing mechanism can adapt to chassis of different sizes and ensure that the chassis can be accurately aligned for the subsequent smooth progress of automated operations.

[0010] The driving cylinder is installed on one side of the processing mechanism to provide power for the pushing component. Through the connection between the output end of the driving cylinder and the pushing component, the pushing component can push the chassis horizontally, realizing the lateral movement of the chassis within the processing mechanism. This design ensures that the chassis can be accurately moved to the grinding position and maintain a stable state for the next operation.

[0011] Next to the driving cylinder, a clamping mechanism is installed. This mechanism adopts a dual mechanism of adsorption and expansion and contraction. It can first position the chassis in parallel through the adsorption device, and then realize the clamping and fixing of the chassis through the expansion and contraction of the internal components. This dual clamping method ensures the stability of the chassis during the grinding process, prevents the positioning deviation caused by the vibration or movement of the chassis, and ensures the accuracy and consistency of grinding.

[0012] The fixing mechanism is installed on the top of the processing mechanism, and its function is to further push the chassis towards the inner side of the processing mechanism, so that the chassis is fixed in three-dimensional directions and maintains a stable posture. This multi-angle fixing scheme improves the reliability of the processing process and reduces the quality defects caused by the loosening of the workpiece.

[0013] A moving base is set next to the processing mechanism, and a grinding machine is installed on the base. Driven by the moving base, the grinding machine can perform translational and reciprocating movements to grind the edges and corners of the chassis. The combined design of the moving base and the grinding machine can achieve precise grinding of the edges of the chassis, with a clear and controllable grinding path, making the entire processing process highly automated and extremely efficient.

[0014] The processing mechanism is composed of a processing frame, a sliding groove, a grinding port and mounting holes. The processing frame is installed on the bracket as the load-bearing structure of the overall device. The sliding groove is opened on the bottom surface of the processing frame to facilitate the smooth sliding of the chassis during the processing process and ensure accurate positioning. The side of the processing frame is provided with a grinding port to facilitate the grinding machine to directly contact the edge and corner positions of the chassis during operation for precise grinding. The mounting holes are located on the side of the processing frame and are used to fix other additional components to make each component more stable and improve the overall processing efficiency and accuracy of the device.

[0015] The pushing component consists of a pushing rod, a pushing plate, and anti-slip strips. The pushing rod is installed at the output end of the driving cylinder and drives the entire component to move through the power provided by the cylinder. The pushing plate is fixed to the side of the pushing rod and is used to directly contact and push the chassis to achieve smooth movement. The surface of the pushing plate is covered with anti-slip strips, which can effectively increase the friction force, prevent the chassis from sliding or shifting during the movement, ensure the smoothness and accuracy of the pushing process, and improve the operation stability and safety of the device.

[0016] The clamping mechanism consists of a clamping frame, sliding blocks, mounting grooves, and rotating shafts, and is designed to ensure the stability and positioning accuracy of the chassis during grinding. The clamping frame is installed on the top of the processing mechanism, providing an overall support structure. The sliding blocks are located below the clamping frame and are designed in a "convex" shape, making it easier to move and adjust within the clamping frame, thus achieving adaptive clamping of the chassis. Mounting grooves are provided inside the sliding blocks to provide fixed positions for the installation of the rotating shafts. A total of 4 rotating shafts are provided in the device, divided into two groups and arranged in parallel in the mounting grooves. This dual-group structure not only increases the clamping stability but also enables more precise positioning. Through the coordinated operation of these four rotating shafts, the clamping mechanism can effectively avoid the offset of the chassis during the grinding process, improving the consistency of the processing quality and the safety of the operation.

[0017] The clamping mechanism also includes a rotating belt and diagonal stripes, further enhancing the efficiency and stability of the clamping process. The rotating belt is installed on the outer side of the rotating shaft and is designed to fit tightly with the rotating shaft, enabling it to smoothly drive the rotating shaft to rotate. The surface of the rotating belt is made of wear-resistant material, which not only improves the durability but also effectively reduces the wear generated during long-term operation, thereby extending the service life of the device. At the same time, diagonal stripes are provided on the surface of the rotating belt. This design can increase the friction force, improve the clamping stability, and prevent the chassis from sliding or loosening during the clamping and grinding processes. Through this combined design, the clamping mechanism can maintain good adaptability and reliability in the processing of various chassis, ensuring the consistency and safety of the processing effect.

[0018] The fixing mechanism consists of a fixing block, rubber strips, rubber protrusions, telescopic grooves, limit sliding grooves, fixing components and return springs, aiming to ensure the stable positioning of the chassis during the processing. The fixing block is installed on the side of the processing mechanism and serves as the main supporting part of the entire fixing mechanism. The rubber strips are located on the upper and lower parts of the surface of the fixing block and are symmetrically arranged obliquely on the central plane of the fixing block, which can effectively increase the friction with the chassis and prevent the chassis from sliding during clamping or grinding. Rubber protrusions are provided in the middle part of the rubber strips, enhancing the fit between the contact surface and the chassis and ensuring a more secure clamping effect. The design of the telescopic grooves and limit sliding grooves enables the fixing components to be adjusted according to the different sizes of the chassis during operation, flexibly adapting to various models of chassis and improving the versatility of the equipment. At the same time, the function of the return springs is to ensure that the fixing mechanism can be quickly reset after clamping is completed, preparing for the processing of the next workpiece. This series of designs effectively improves the operating stability and adaptability of the fixing mechanism.

[0019] The fixing mechanism also includes telescopic grooves, limit sliding grooves, fixing components and return springs, aiming to enhance the flexibility and reliability of the chassis fixation. The telescopic grooves are opened in the middle part of the fixing block, enabling the fixing components to move freely therein, thus adapting to chassis of different sizes. The limit sliding grooves are provided on the inner side surfaces of the telescopic grooves, providing a guiding system to ensure the stability of the fixing components during movement and preventing deviation or jamming. This design not only improves the accuracy of clamping and fixation but also helps to simplify the operation process during work.

[0020] The fixing components are installed in the telescopic grooves and can precisely adjust their positions through cooperation with the limit sliding grooves to ensure that the chassis can be safely clamped. At the same time, the return springs are installed below the fixing components and are responsible for quickly resetting the fixing components to the initial position after the clamping action is completed. This mechanism ensures the rapid switching between clamping and relaxation of the fixing mechanism, improves work efficiency, makes the processing process of the chassis more smooth, can quickly respond to different production requirements, and significantly enhances the adaptability and practicality of the equipment.

[0021] The fixing components are composed of telescopic blocks, limit sliders, support rings, fixing suction cups and mating grooves, and are designed to achieve precise clamping and fixation of the chassis. The telescopic blocks are installed in the telescopic grooves and can move freely therein, thus being flexibly adjusted according to the sizes of different chassis. The limit sliders are installed on the four side surfaces of the telescopic blocks to ensure the stability of the telescopic blocks during movement and prevent jamming or uneven clamping.

[0022] The support ring is installed on the side of the telescopic block to provide additional support and stability for the fixed component. The fixed suction cup is installed in the central part of the support ring, and the vacuum principle is used to achieve close adsorption of the chassis surface, ensuring that the chassis is firmly fixed during the processing. In order to further enhance the fixing effect, the matching groove is opened on the outer surface of the fixed suction cup, which can form a good match with the chassis surface, increase the contact area, and improve the adsorption force. Through this series of designs, the fixed component not only improves the clamping effect of the chassis, but also significantly enhances the simplicity and safety of operation, ensuring the efficiency and accuracy of the processing process.

[0023] The cross-sectional graphics of the limit slider and the limit chute are set to trapezoidal, which brings advantages in many aspects, especially in terms of the sliding performance and stability of the fixed component. The trapezoidal design enables the limit slider to better maintain a relatively stable position when sliding in the limit chute. Compared with other shapes, the geometric characteristics of the trapezoid can prevent the slider from shaking too much in the chute, thereby reducing the risk of jamming and improving the smoothness of operation. The trapezoidal shape helps with self-centering, making the slider move more smoothly in the chute. When the slider slides, due to its shape characteristics, it can automatically adjust to the best contact position, avoiding friction and wear caused by misalignment, thereby extending the service life of the component.

[0024] The fixing assembly also includes a gas flow channel, which is designed to be mainly opened inside the telescopic block and the fixed suction cup, and has important functions and effects. An air pump is provided at one end of the fixing assembly, and the main function of the air pump is to perform vacuum treatment on the fixed suction cup so as to effectively adsorb and fix the computer case. Through the structural design of the gas flow channel, the air pump can quickly extract air to form a negative pressure environment, so that the fixed suction cup is tightly adsorbed on the surface of the case.

[0025] The application of this vacuum adsorption technology brings several advantages. First, the design of the gas flow channel ensures efficient air flow transmission between the air pump and the suction cup, ensuring the rapid formation of vacuum. Compared with traditional mechanical clamping methods, vacuum adsorption can provide more uniform clamping force, reduce the risk of damage to the chassis surface, and thus improve the fixing stability and safety of the chassis.

[0026] The present invention also discloses a method for using the above-mentioned grinding device for processing a computer case, comprising the following steps:

[0027] S1. Place the computer case on the processing frame of the processing mechanism;

[0028] S2. Start the clamping mechanism, slide the sliding block along the sliding groove, drive the clamping frame to move toward the inner side of the processing frame, make the side of the chassis contact the inner side of the processing frame and adjust the angle;

[0029] S3. The driving cylinder is activated, and the push rod of the pushing component drives the push plate to laterally push the chassis. The anti-slip strips provide static friction to ensure the horizontal displacement of the chassis.

[0030] S4. During the movement of the chassis, the rotating belt of the clamping mechanism contacts the chassis and drives the rotating shaft to rotate, further clamping the chassis.

[0031] S5. The air pump of the fixing mechanism enables the fixing suction cups to adsorb the surface of the chassis through the gas flow channels. The telescopic block slides along the telescopic groove, and the rubber strip and rubber protrusions limit the displacement of the chassis.

[0032] S6. The moving base drives the grinding machine to perform translational reciprocating grinding on the edges and corners of the chassis.

[0033] S7. After one side of grinding is completed, change the surface and repeat steps S1 - S6 until all edges and corners are ground.

[0034] The beneficial effects of the present invention are as follows:

[0035] 1. In the present invention, only by placing the chassis into the device, the automated fixing, clamping, and pushing systems can complete various operations, reducing the steps of manual fixing and manual grinding, making the whole process more smooth and efficient, and suitable for mass production. The automated grinding device can ensure uniform grinding of each edge and corner, reducing the common deviations in manual operations, improving the smoothness and consistency of grinding, and thus enhancing the overall quality and aesthetics of the product. The present invention is adapted to chassis of different specifications, enhancing the flexibility of the device. The fixing, clamping, and pushing components can automatically adapt to chassis of different sizes and shapes, reducing the time for adjusting the device and improving the versatility of the device, which is suitable for the rapid switching of different models of products in production.

[0036] 2. On the one hand, the present invention reduces the labor intensity and ensures operation safety. The device automatically completes clamping and grinding, reducing the chance for workers to contact high-speed rotating grinding tools, thereby reducing the operation risk. At the same time, workers only need to perform simple operations and do not need to perform repetitive fixing actions for a long time, reducing muscle strain and fatigue. It improves the production efficiency of the device and saves costs: The application of the automated device not only reduces the manual operation time but also improves the production efficiency. In the long-term use, it can save labor costs and increase the output of the production line, which is beneficial to the control of production costs and the improvement of profits. The automated clamping and grinding design can complete processing in a closed device, which helps to cooperate with dust collection and exhaust equipment to control dust emissions, reduce dust pollution in the workshop, and thus optimize the working environment and the health protection of workers.

[0037] In summary, the present invention not only improves the efficiency and quality but also reduces the labor intensity and safety risks, making the device have good practicality and economic benefits. Description of the Drawings

Specific Embodiments

[0049] To better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings of the specification and specific embodiments.

[0050] Embodiment

[0051] As Figure 1-8 shown, a grinding device for computer chassis processing aims to achieve automatic grinding treatment of the chassis corners, improve processing efficiency, and reduce the risk of manual operation. The device includes a bracket 1, a processing mechanism 2, a driving cylinder 3, a pushing component 4, a clamping mechanism 5, a fixing mechanism 6, a moving base 7, and a grinding machine 8. Each component cooperates closely to jointly complete the precise fixation of the chassis and the grinding of the corners.

[0052] Among them, the bracket 1 is the basic framework of the entire device, used to support and fix each processing component, providing a stable working platform. Above the bracket 1 is installed the processing mechanism 2, which is a key device for accommodating the chassis and has positioning and fixing functions. The structural design of the processing mechanism 2 can adapt to chassis of different sizes and ensure that the chassis can be accurately aligned for the subsequent smooth progress of automated operations.

[0053] The driving cylinder 3 is installed on one side of the processing mechanism 2 to provide power for the pushing component 4. Through the connection between the output end of the driving cylinder 3 and the pushing component 4, the pushing component 4 can push the chassis horizontally, realizing the lateral movement of the chassis within the processing mechanism 2. This design ensures that the chassis can be accurately moved to the grinding position and maintain a stable state for the next operation.

[0054] Next to the driving cylinder 3, the clamping mechanism 5 is installed. This mechanism adopts a dual mechanism of adsorption and expansion. It can first position the chassis in parallel through the adsorption device and then achieve the clamping and fixation of the chassis through the expansion of the internal components. This dual clamping method ensures the stability of the chassis during the grinding process, preventing the positioning deviation of the chassis caused by vibration or movement, and ensuring the accuracy and consistency of grinding.

[0055] The fixing mechanism 6 is installed on the top of the processing mechanism 2, and its function is to further push the chassis towards the inner side of the processing mechanism 2, so that the chassis is fixed in three-dimensional directions and maintains a stable posture. This multi-angle fixing scheme improves the reliability of the processing process and reduces the quality defects caused by workpiece loosening.

[0056] Next to the processing mechanism 2, a moving base 7 is set, and a grinding machine 8 is installed on the base. The grinding machine 8 can perform translational and reciprocating motions driven by the moving base 7, and the corners of the chassis are ground through this device. The combined design of the moving base 7 and the grinding machine 8 can achieve precise grinding of the chassis edge, with a clear and controllable grinding path, making the entire processing process highly automated and extremely efficient.

[0057] As shown Figure 2 in the figure, the processing mechanism 2 is composed of a processing frame 21, a sliding groove 22, a grinding port 23, and mounting holes 24. The processing frame 21 is mounted on the bracket 1 and serves as the load-bearing structure of the overall device. The sliding groove 22 is opened on the bottom surface of the processing frame 21 to facilitate the smooth sliding of the chassis during the processing, ensuring accurate positioning. The grinding port 23 is provided on the side of the processing frame 21 to facilitate the direct contact of the grinding machine 8 with the corner positions of the chassis during operation for precise grinding. The mounting holes 24 are located on the side of the processing frame 21 for fixing other additional components, making each component more stable and improving the overall processing efficiency and accuracy of the device.

[0058] As shown Figure 3 in the figure, the pushing component 4 is composed of a push rod 41, a push plate 42, and anti-slip strips 43. Among them, the push rod 41 is mounted on the output end of the driving cylinder 3, and the entire component is pushed by the power provided by the cylinder. The push plate 42 is fixed to the side of the push rod 41 for directly contacting and pushing the chassis to achieve smooth movement. The surface of the push plate 42 is covered with anti-slip strips 43, which can effectively increase the friction force, prevent the chassis from sliding or shifting during the movement, ensure the smoothness and accuracy of the pushing process, and improve the operation stability and safety of the device.

[0059] As shown Figure 4 in the figure, the clamping mechanism 5 is composed of a clamping frame 51, a sliding block 52, a mounting groove 53, and a rotating shaft 54, and is designed to ensure the stability and positioning accuracy of the chassis during grinding. The clamping frame 51 is mounted on the top of the processing mechanism 2 to provide the overall support structure. The sliding block 52 is located below the clamping frame 51 and is designed in a "convex" shape to make it easier to move and adjust within the clamping frame 51, thereby achieving adaptive clamping of the chassis. The mounting groove 53 is provided inside the sliding block 52 to provide a fixed position for the installation of the rotating shaft 54. A total of 4 rotating shafts 54 are provided in the device, which are divided into two groups and arranged in parallel in the mounting groove 53. Such a double-group structure not only increases the clamping stability but also enables more accurate positioning. Through the coordinated operation of these four rotating shafts 54, the clamping mechanism 5 can effectively avoid the offset of the chassis during the grinding process, improving the consistency of the processing quality and the safety of the operation.

[0060] The clamping mechanism 5 further includes a rotating belt 55 and diagonal stripes 56, which further enhance the efficiency and stability of the clamping process. The rotating belt 55 is installed on the outer side of the rotating shaft 54 and is designed to fit tightly with the rotating shaft 54, enabling it to smoothly drive the rotating shaft 54 to rotate. The surface of the rotating belt 55 is made of wear-resistant material, which not only improves durability but also effectively reduces wear generated during long-term operation, thereby extending the service life of the device. At the same time, diagonal stripes 56 are provided on the surface of the rotating belt 55. This design can increase friction, improve the stability of clamping, and prevent the chassis from sliding or loosening during the clamping and grinding processes. Through this combined design, the clamping mechanism 5 can maintain good adaptability and reliability in the processing of various chassis, ensuring the consistency and safety of the processing effect.

[0061] As Figure 6 shown, the fixing mechanism 6 is composed of a fixing block 61, a rubber strip 62, rubber protrusions 63, a telescopic groove 64, a limit sliding groove 65, a fixing component 66, and a return spring 67, aiming to ensure the stable positioning of the chassis during the processing. The fixing block 61 is installed on the side of the processing mechanism 2 and serves as the main support part of the entire fixing mechanism 6. The rubber strip 62 is located at the upper and lower parts of the surface of the fixing block 61 and is symmetrically arranged obliquely on the central plane of the fixing block 61, which can effectively increase the friction with the chassis and prevent the chassis from sliding during the clamping or grinding process. Rubber protrusions 63 are provided in the middle part of the rubber strip 62, enhancing the fit between the contact surface and the chassis and ensuring a more secure clamping effect. The design of the telescopic groove 64 and the limit sliding groove 65 enables the fixing component 66 to be adjusted according to the different sizes of the chassis during operation, flexibly adapting to various models of chassis and improving the versatility of the device. At the same time, the function of the return spring 67 is to ensure that after the clamping is completed, the fixing mechanism 6 can be quickly reset to prepare for the processing of the next workpiece. This series of designs effectively improves the operating stability and adaptability of the fixing mechanism 6.

[0062] The fixing mechanism 6 further includes a telescopic groove 64, a limit sliding groove 65, a fixing component 66, and a return spring 67, aiming to enhance the flexibility and reliability of the chassis fixing. The telescopic groove 64 is opened in the middle part of the fixing block 61, enabling the fixing component 66 to move freely therein, thereby adapting to different sizes of the chassis. The limit sliding groove 65 is provided on the inner side surface of the telescopic groove 64, providing a guiding system to ensure that the fixing component 66 remains stable during movement, preventing deviation or jamming. This design not only improves the accuracy of clamping and fixing but also helps to simplify the operation process during work.

[0063] The fixing assembly 66 is installed in the telescopic slot 64. By cooperating with the limiting slide slot 65, its position can be precisely adjusted to ensure that the chassis can be safely clamped. At the same time, the reset spring 67 is installed below the fixing assembly 66, which is responsible for quickly resetting the fixing assembly 66 to the initial position after the clamping action is completed. This mechanism ensures the fast switching of the fixing mechanism 6 between clamping and loosening, improves work efficiency, makes the processing process of the chassis smoother, can quickly respond to different production needs, and significantly improves the adaptability and practicality of the equipment.

[0064] like Figure 7 As shown, the fixing assembly 66 is composed of a telescopic block 661, a limiting slider 662, a support ring 663, a fixing suction cup 664 and a matching groove 665, and is designed to achieve accurate clamping and fixing of the chassis. The telescopic block 661 is installed in the telescopic groove 64 and can move freely therein, so as to be flexibly adjusted according to the size of different chassis. The limiting slider 662 is installed on the four sides of the telescopic block 661 to ensure that the telescopic block 661 remains stable when moving to prevent jamming or uneven clamping.

[0065] The support ring 663 is installed on the side of the telescopic block 661 to provide additional support and stability for the fixing component 66. The fixing suction cup 664 is installed in the central part of the support ring 663, and the vacuum principle is used to achieve close adsorption to the surface of the chassis, ensuring that the chassis is firmly fixed during the processing. In order to further enhance the fixing effect, a matching groove 665 is opened on the outer surface of the fixing suction cup 664, which can form a good match with the surface of the chassis, increase the contact area, and improve the adsorption force. Through this series of designs, the fixing component 66 not only improves the clamping effect of the chassis, but also significantly enhances the simplicity and safety of operation, ensuring the efficiency and accuracy of the processing process.

[0066] The cross-sectional graphics of the limiting slider 662 and the limiting chute 65 are set to a trapezoid, which brings advantages in many aspects, especially in terms of the sliding performance and stability of the fixed component 66. The trapezoidal design enables the limiting slider 662 to better maintain a relatively stable position when sliding in the limiting chute 65. Compared with other shapes, the geometric characteristics of the trapezoid can prevent the slider from shaking too much in the chute, thereby reducing the risk of jamming and improving the smoothness of operation. The trapezoidal shape helps with self-centering, making the movement of the slider in the chute smoother. When the slider slides, due to its shape characteristics, it can automatically adjust to the optimal contact position, avoiding friction and wear caused by misalignment, thereby extending the service life of the component.

[0067] The fixed component 66 further includes a gas flow channel 666, which is mainly designed inside the telescopic block 661 and the fixed suction cup 664 and has important functions. An air pump is provided at one end of the fixed component 66. The main function of the air pump is to perform vacuum treatment on the fixed suction cup 664 so as to effectively adsorb and fix the computer chassis. Through the structural design of the gas flow channel 666, the air pump can quickly extract air to form a negative pressure environment, so that the fixed suction cup 664 tightly adheres to the surface of the chassis.

[0068] The application of this vacuum adsorption technology brings multiple advantages. First of all, the design of the gas flow channel 666 ensures efficient air flow transmission between the air pump and the suction cup, ensuring the rapid formation of a vacuum. Compared with traditional mechanical clamping methods, vacuum adsorption can provide a more uniform clamping force, reducing the risk of damage to the surface of the chassis, thereby improving the fixing stability and safety of the chassis.

[0069] As Figure 8 shown, during the working process of the present invention, the welded computer chassis is placed in the processing frame 21 by a worker or a manipulator, and the clamping mechanism 5 is started first:

[0070] The sliding block 52 slides in the sliding groove 22, thereby driving the clamping frame 51 to move towards the inner side of the processing frame 21. After contacting the computer chassis, it slowly corrects the angle until it is pushed to the deepest position, and the side of the computer chassis completely contacts the inner side of the processing frame 21;

[0071] The driving cylinder 3 is started, driving the push rod 41 and the push plate 42 to move. The push plate 42 slowly pushes the computer chassis to move horizontally, and the anti-slip strip 43 provides a horizontal static friction force during this process to ensure that the chassis maintains a horizontal displacement;

[0072] During the process of the chassis being pushed by the pushing component 4, the side of the chassis is always in contact with the rotating belt 55, and the static friction force generated between the two causes the rotating belt 55 to drive the rotating shaft 54 to rotate, thereby realizing the horizontal transverse movement of the chassis;

[0073] The chassis is pushed to contact the fixed suction cup 664. The air pump provided on the side of the fixed block 61 makes the fixed suction cup 664 inhale close to a vacuum state through the gas flow channel 666. The shape of the fixed suction cup 664 changes, and it is clamped on the support ring 663 through the groove 665 to ensure stability, so that the fixed suction cup 664 can adsorb the chassis; during the further pushing process of the pushing component 4, the telescopic block 661 slides into the telescopic groove 64 against the elastic force of the return spring 67, and the chassis can thus contact the rubber strip 62 and the rubber protrusion 63, further restricting the displacement trend of the chassis and improving stability;

[0074] The chassis bears the pressure from the pushing component 4, the clamping mechanism 5, and the fixing mechanism 6 in three directions respectively, as well as the static friction force of each rubber component, ensuring its stability during the grinding process;

[0075] The moving base 7 drives the grinding machine 8 to grind the corners of the chassis. After one side is completed, the surface is changed manually or by a manipulator to continue grinding until all corners are ground.

[0076] Specifically, in one embodiment, the usage method of the above-mentioned grinding device for computer chassis processing includes the following steps:

[0077] S1. Place the computer chassis on the processing frame 21 of the processing mechanism 2;

[0078] S2. Start the clamping mechanism 5. The sliding block 52 slides along the sliding groove 22, driving the clamping frame 51 to move towards the inner side of the processing frame 21, so that the side of the chassis contacts the inner side of the processing frame 21 and the angle is adjusted;

[0079] S3. Start the driving cylinder 3. The push rod 41 of the pushing component 4 drives the push plate 42 to laterally push the chassis, and the anti-slip strip 43 provides static friction to ensure the horizontal displacement of the chassis;

[0080] S4. During the movement of the chassis, the rotating belt 55 of the clamping mechanism 5 contacts the chassis, driving the rotating shaft 54 to rotate, further clamping the chassis;

[0081] S5. The air pump of the fixing mechanism 6 makes the fixing suction cup 664 adsorb the surface of the chassis through the gas flow channel 666. The telescopic block 661 slides along the telescopic groove 64, and the rubber strip 62 and the rubber protrusion 63 limit the displacement of the chassis;

[0082] S6. The moving base 7 drives the grinding machine 8 to perform translational reciprocating grinding on the corners of the chassis;

[0083] S7. After one side is ground, change the surface and repeat steps S1 - S6 until all corners are ground.

[0084] More specifically, in one embodiment, the usage method of the above-mentioned grinding device for computer chassis processing includes the following steps:

[0085] A usage method of a grinding device for computer chassis processing includes the following steps:

[0086] S1. Place the computer chassis on the processing frame 21 of the processing mechanism 2, and adjust the position of the chassis through the sliding groove 22 so that the chassis is aligned with the mounting hole 24 on the side of the processing frame 21;

[0087] S2. Activate the clamping mechanism 5. The slider 52 slides along the sliding groove 22, driving the clamping frame 51 to move towards the inner side of the processing frame 21. The rotating shaft 54 rotates in the mounting groove 53. Frictional force is generated by the contact between the inclined stripes 56 on the surface of the rotating belt 55 and the chassis, driving the chassis to be horizontally aligned and preliminarily clamped.

[0088] S3. Activate the driving cylinder 3. The push rod 41 of the pushing component 4 drives the push plate 42 to horizontally push the chassis. The anti-slip strips 43 on the surface of the push plate 42 provide static friction to ensure that the chassis is horizontally displaced along the sliding groove 22 to the preset position.

[0089] S4. Activate the fixing mechanism 6. The air pump in the fixing block 61 extracts the air inside the fixing suction cup 664 through the gas flow channel 666 to form a vacuum adsorption. It cooperates with the groove 665 to fit the surface of the chassis. The telescopic block 661 slides along the telescopic groove 64. The trapezoidal cross-section of the limit slider 662 and the limit sliding groove 65 cooperate for guiding. The rubber strip 62 and the rubber protrusion 63 simultaneously press the surface of the chassis tightly. The return spring 67 stores energy when the telescopic block 661 moves.

[0090] S5. The moving base 7 drives the grinding machine 8 to perform a reciprocating translational motion along the grinding port 23 on the side of the processing frame 21 to precisely grind the corners of the chassis.

[0091] S6. After finishing grinding one side, the air pump releases the vacuum adsorption. The return spring 67 pushes the fixing component 66 to reset. The rotating shaft 54 of the clamping mechanism 5 rotates in the reverse direction to release the chassis. The pushing component 4 retracts to the initial position.

[0092] S7. After turning the chassis over and re-placing it on the processing frame 21, repeat steps S2 to S6, and use the mounting holes 24 for positioning until all corners are ground.

[0093] S8. After grinding, reset all components on the support 1 and clean the residual dust inside the processing frame 21.
