Description

Technical Field

[0001] The present application relates to the technical field of stainless steel processing, and in particular to a stainless steel polishing and grinding device and a fixing bracket. Background Art

[0002] With the development of modern industry, stainless steel has been widely used in many fields such as construction, kitchenware, chemical equipment, etc. due to its excellent corrosion resistance and aesthetics. In the production process of stainless steel products, polishing is a crucial process, which directly affects the surface finish and overall quality of the product.

[0003] Existing stainless steel grinding devices mostly use mechanical or electric methods to drive the grinding tools to perform fine processing on the surface of stainless steel plates. In order to keep the working environment clean, vacuum cleaners or other forms of dust removal devices are usually installed near the grinding area to suck away the stainless steel chips generated during the grinding process through the negative pressure principle, so as to reduce the pollution of waste chips to the environment and the interference with subsequent processing procedures.

[0004] However, in actual operation, although these dust removal devices have played a cleaning role to a certain extent, they still have significant shortcomings. In particular, in the side areas of the grinding device, there are often blind spots for cleaning due to uneven airflow distribution, limited suction range of the vacuum cleaner, or the influence of the distribution characteristics of the waste chips. These waste chips that are not cleaned in time will gradually accumulate, which may not only scratch the surface of the stainless steel plate, affecting the finish and consistency of the grinding effect, but also increase the wear of the equipment and shorten its service life.

[0005] Therefore, the present application provides a stainless steel polishing and grinding device and a fixing bracket to solve the above problems. Summary of the invention

These wastes that are not cleaned in time will gradually accumulate, which may not only scratch the surface of the stainless steel plate, affect the finish and consistency of the polishing effect, but also increase the wear of the equipment and shorten the service life.

[0007] To achieve the above-mentioned purpose, on the one hand, the present application provides a stainless steel polishing and grinding device, comprising: a grinding table, a grinding device body disposed on the grinding table, a support structure disposed on the grinding table, a driving structure disposed on the support structure and connected to the grinding device body for driving the grinding device body to move closer to or away from the grinding table, and a dust suction structure disposed on the support structure and connected to the grinding device body for removing dust from the stainless steel surface; and also comprising a clamping structure disposed on the grinding table for clamping and fixing the stainless steel; The difference from the existing polishing and grinding devices is that: in order to facilitate the cleaning of the stainless steel waste on the side of the grinding device body: the dust suction structure includes a vacuum cleaner fixedly arranged on the upper end of the bracket structure, a dust hood fixedly mounted on the grinding device body and connected to the vacuum cleaner, and a fan blade arranged on the grinding device body, and the dust hood is connected to the vacuum cleaner through a bellows.

Through the ingenious coordination of the shell and the dust hood and the optimized design of the internal shape of the shell, the cleaning effect of the waste chips on the sides of the grinding device body is significantly improved, and the residue and escape of waste chips in the working environment are reduced.

[0014] Preferably, in order to prevent the stainless steel from slipping with the clamping plate, the clamping plate is processed with anti-skid teeth at one end close to the stainless steel.

[0018] The present application significantly improves the cleaning effect of the waste chips on the side of the grinding device body through the clever coordination of the shell and the dust hood and the optimized design of the internal shape of the shell, and reduces the residue and escape of waste chips in the working environment. The conical design of the bottom of the shell enhances the downward airflow strength, making it easier for waste chips to be blown away and guided into the dust hood, thereby improving the dust collection efficiency of the vacuum cleaner.

[0021] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0022] This embodiment provides a stainless steel polishing and grinding device, such as Figure 1-6 As shown, the grinding device includes a grinding table 1, a grinding device body 2 arranged on the grinding table 1, a support structure 3 arranged on the grinding table 1, a driving structure 4 arranged on the support structure 3 and connected to the grinding device body 2 for driving the grinding device body 2 to move closer to or away from the grinding table 1, and a dust suction structure 5 arranged on the support structure 3 and connected to the grinding device body 2 for removing dust from the stainless steel surface; and also includes a clamping structure 6 arranged on the grinding table 1 for clamping and fixing the stainless steel; Different from the existing polishing and grinding devices, in order to facilitate the cleaning of the stainless steel waste chips on the side of the grinding device body 2: the dust suction structure 5 includes a dust collector 51 fixedly arranged on the upper end of the support structure 3, a dust hood 52 fixedly mounted on the grinding device body 2 and connected to the dust collector 51, and a fan blade 53 arranged on the grinding device body 2, and the dust hood 52 is connected to the dust collector 51 through a bellows 54. Among them, traditional grinding equipment often ignores the problem of handling waste chips generated during the grinding process, resulting in a poor working environment and affecting the health of operators. The dust suction structure 5 of the present invention cleverly solves this problem. The dust hood 52 is arranged close to the grinding device body 2, and is flexibly connected to the dust collector 51 through the bellows 54, thereby ensuring the dust suction effect. The fan blade 53 uses the rotational power of the rotating rod 22 to synchronously generate airflow during the grinding process, blow away the waste generated by grinding from the contact part between the grinding sheet 24 and the stainless steel, and guide it into the dust cover 52, and finally suck it in and collect it by the dust collector 51, realizing an efficient operation mode of dust removal while grinding. By optimizing the structural design of the dust collection structure 5, during the grinding process, the rotational power on the grinding device body 2 is used to drive the fan blade 53 to rotate, and airflow is synchronously generated during the grinding process, blowing away the waste generated by grinding from the contact part between the grinding sheet 24 and the stainless steel, and guiding it into the dust cover 52, and finally sucking it in and collecting it by the dust collector 51, realizing an efficient operation mode of dust removal while grinding, improving the grinding efficiency and surface quality, effectively reducing the dust pollution generated during the grinding process, and protecting the health of the operator. During operation, the stainless steel workpiece to be polished is first fixed on the grinding table 1 through the clamping structure 6. Then, the stainless steel surface is polished by the grinding device body 2. At the same time, the fan blades 53 generate airflow under the drive of the grinding device body 2, blow away the waste chips generated by grinding and guide them into the dust cover 52. Finally, the dust collector 51 sucks and collects the waste chips in the dust cover 52 through the bellows 54, completing the entire grinding and dust removal process.

[0023] Specifically, in order to improve the dust collection effect of the vacuum cleaner 51: the dust hood 52 is in a cone shape with a small top and a large bottom. Among them, the conical dust hood 52 can more effectively guide and concentrate the waste chips generated during the grinding process. Since the grinding sheet 24 is located below the dust hood 52 and works with the rotation of the rotating rod 22, the waste chips are often thrown out at a certain angle. The conical design makes the opening of the dust hood 52 gradually increase, forming a natural "funnel" effect. The waste chips are more easily guided to the depth of the dust hood 52 under the push of the airflow, thereby reducing the possibility of waste chips escaping. In addition, the conical dust hood 52 also helps to enhance the suction force of the vacuum cleaner 51. When the waste chips are concentrated and guided to the depth of the dust hood 52, the distance between the suction port of the vacuum cleaner 51 and the waste chips is shortened, making the suction force more concentrated and effective. This design not only improves the dust collection efficiency, but also reduces the energy consumption of the vacuum cleaner 51, achieving the purpose of energy saving and environmental protection. The conical dust hood 52 effectively guides and concentrates the waste chips, significantly improves the dust collection effect of the vacuum cleaner 51, and reduces the dust pollution in the working environment. When working, the dust hood 52, with its unique conical design, first blows away the waste chips generated by the contact part between the grinding sheet 24 and the stainless steel through the airflow generated by the fan blades 53 and initially guides them to the entrance of the dust hood 52. Subsequently, under the guidance of the conical dust hood 52, the waste chips are further concentrated and guided to the depth of the dust hood 52 along the gradually increasing opening. At this time, the vacuum cleaner 51 is connected to the dust hood 52 through the bellows 54, and uses its powerful suction force to suck in and collect the waste chips. In the whole process, the conical dust hood 52 plays a vital role. It not only improves the dust collection efficiency, but also ensures the smooth progress of the dust collection process.

[0024] Specifically, the grinding device body 2 includes a shell 21, a rotating rod 22 rotatably plugged into the shell 21, a driving motor 23 arranged at the upper end of the shell 21 for driving the rotating rod 22 to rotate, and a grinding sheet 24 fixedly installed at the lower end of the rotating rod 22, wherein the output end of the driving motor 23 is fixedly connected to the upper end of the rotating rod 22, the dust cover 52 is fixedly sleeved on the outside of the shell 21, and the fan blade 53 is fixedly sleeved on the rotating rod 22 corresponding to the grinding sheet 24 and the shell 21. Among them, the shell 21 serves as a supporting structure, and electrical control components are integrated inside to ensure the stable operation of the entire grinding process. The rotating rod 22 is rotatably plugged into the shell 21 through a precision bearing assembly to ensure stability and precision during the rotation process. The driving motor 23 uses a high-performance DC motor, which transmits power to the rotating rod 22 through a gear reduction mechanism to drive it to rotate at high speed. The grinding sheet 24 is made of high-quality diamond or silicon carbide material, which has high hardness, high wear resistance and good self-sharpening property, and can quickly remove the oxide layer, scratches and other defects on the surface of stainless steel to achieve an ideal surface finish. The combined design of the dust hood 52 and the fan blade 53 effectively reduces the dust pollution generated during the grinding process and protects the health of the operator and the quality of the environment. During operation, the drive motor 23 starts and drives the rotating rod 22 to rotate. The rotating rod 22 drives the grinding sheet 24 to rotate at a high speed, contacts the stainless steel surface and produces a grinding effect. At the same time, the fan blade 53 generates an airflow driven by the rotating rod 22, blows away the waste generated during the grinding process and guides it into the dust hood 52. The dust collector 51 is connected to the dust hood 52 through the bellows 54, and uses its strong suction to suck in and collect the waste. During the whole process, the grinding device body 2 and the dust suction structure 5 are closely matched to achieve efficient and environmentally friendly grinding operations.

[0025] Furthermore, in order to improve the effect of cleaning the waste chips on the side of the grinding device body 2: the top shape of the shell 21 is consistent with the shape of the dust hood 52, and the shape of the bottom of the shell 21 is opposite to the shape of the dust hood 52, that is, the bottom shape of the shell 21 is a cone shape with a large top and a small bottom, and the shape of the inner wall of the shell 21 is consistent with the shape of the outer wall of the shell 21. Among them, the top shape of the shell 21 is designed to be consistent with the dust hood 52, that is, it is also a cone shape with a small top and a large bottom. Such a design enables the dust hood 52 to fit tightly on the top of the shell 21, reducing the escape space between the airflow and the waste chips, and improving the dust collection efficiency. At the same time, the bottom shape of the shell 21 is opposite to the dust hood 52, and is designed to be a cone shape with a large top and a small bottom. This design is not arbitrary, but is based on aerodynamic considerations. When the fan blade 53 rotates under the drive of the rotating rod 22 to generate airflow, the airflow will flow along the inner wall of the shell 21. Since the bottom of the shell 21 is in a cone shape, the airflow will gradually accelerate and concentrate during the downward flow, forming a strong downward airflow. This airflow not only helps to blow away the waste chips around the grinding sheet 24 and guide them into the dust cover 52, but also reduces the deposition and accumulation of waste chips at the bottom of the shell 21 to a certain extent. In addition, in order to maintain the smoothness and stability of the airflow, the shape of the inner wall of the shell 21 is also designed to be consistent with the shape of the outer wall, that is, it is also conical. Such a design allows the airflow to maintain continuity and consistency when flowing inside the shell 21, reducing the generation of eddy currents and turbulence, thereby improving the cleaning effect of waste chips. Through the ingenious coordination of the shell 21 and the dust cover 52 and the optimized design of the internal shape of the shell 21, the cleaning effect of the waste chips on the side of the grinding device body 2 is significantly improved, and the residue and escape of waste chips in the working environment are reduced. The conical design at the bottom of the shell 21 enhances the downward airflow strength, making it easier for waste chips to be blown away and guided into the dust cover 52, thereby improving the dust collection efficiency of the vacuum cleaner 51. When working, the drive motor 23 starts and drives the rotating rod 22 to rotate. The rotating rod 22 drives the grinding disc 24 to rotate at high speed, contacting the stainless steel surface and producing a grinding effect. At the same time, the fan blades 53 rotate under the drive of the rotating rod 22 to generate airflow. This airflow first flows downward along the inner wall of the shell 21. Since the bottom of the shell 21 is conical, the airflow gradually accelerates and concentrates to form a strong downward airflow. This airflow blows away the waste chips around the grinding disc 24 and guides them into the dust hood 52. The vacuum cleaner 51 is connected to the dust hood 52 through the bellows 54, and uses its strong suction to suck in and collect the waste chips. During the whole process, the ingenious cooperation between the shell 21 and the dust hood 52 and the optimized design of the internal shape of the shell 21 work together to guide and collect the waste chips, realizing efficient and environmentally friendly grinding operations.

[0026] Specifically, the support structure 3 includes a support frame 31 and pillars 32 fixedly connected at the four corners between the support frame 31 and the grinding table 1. During operation, the support frame 31 serves as the main load-bearing component, bearing the gravity from the grinding device body 2 and the workpiece as well as the vibration and impact force generated during operation. The pillars 32 firmly fix the support frame 31 on the grinding table 1 through a fixed connection, ensuring the stability and balance of the entire support structure 3. When the grinding device body 2 is working, the vibration and impact force generated by it will be transmitted to the grinding table 1 through the support frame 31 and the pillars 32, but due to the stability design of the support structure 3, these vibrations and impact forces are effectively dispersed and absorbed, thereby ensuring the smooth operation of the equipment and the safety of the operator.

[0027] Specifically, in order to achieve precise control and adjustment of the grinding device body 2 in three-dimensional space: the driving structure 4 includes a lifting frame 41 arranged between the grinding table 1 and the support frame 31 and mounted on the pillar 32, an X-axis moving mechanism 42 symmetrically fixedly mounted on the lifting frame 41 for driving the grinding device body 2 to move along the X-axis, a Y-axis moving mechanism 43 installed on the X-axis moving mechanism 42 and fixedly connected to the dust cover 52 for driving the grinding device body 2 to move along the Y-axis, a Z-axis moving mechanism 44 fixedly mounted on the top of the support frame 31 and connected to the lifting frame 41 for driving the lifting frame 41 to move along the Z-axis, and a control box 45 arranged on the grinding table 1 and connected to the driving structure 4. The driving structure 4 is a prior art and will not be described in detail here. The design of the driving structure 4 allows the operator to easily adjust the position and posture of the grinding device according to the shape, size and grinding requirements of the workpiece, so as to achieve a wider grinding coverage and a more sophisticated grinding operation. The automated movement control and lifting and lowering adjustment functions reduce manual intervention and downtime, and improve work efficiency and production capacity. During the working process, the operator sends instructions to the drive structure 4 through the control box 45. After receiving the instructions, the control box 45 will coordinate the movement of each moving mechanism. First, the Z-axis moving mechanism 44 drives the lifting frame 41 and all the components thereon to perform lifting and adjustment according to the instructions to set the appropriate grinding height. Then, the X-axis moving mechanism 42 and the Y-axis moving mechanism 43 drive the grinding device body 2 to move along the X-axis and Y-axis respectively according to the preset path or real-time feedback position information. In this way, the grinding device body 2 can perform precise trajectory control and grinding operations on the surface of the workpiece. At the same time, the dust hood 52 moves together with the grinding device body 2 to ensure that waste chips and dust can be effectively collected during the entire grinding process.

[0028] Specifically, in order to facilitate the fixing of the stainless steel on the grinding table 1: the clamping structure 6 includes a guide groove 61 opened on the grinding table 1 along the X-axis direction, a clamping plate 62 symmetrically arranged in the guide groove 61, a bearing plate 63 fixedly arranged at the lower end of the grinding table 1 corresponding to the two ends of the guide groove 61, a bidirectional screw 64 rotatably plugged on the two bearing plates 63, a slide plate 65 threadedly sleeved on the bidirectional screw 64 and fixedly connected to the clamping plate 62, and a drive motor 66 fixedly installed on the bearing plate 63, and the output end of the drive motor 66 is fixedly connected to the end of the bidirectional screw 64. The design of the clamping structure 6 makes the fixing of the stainless steel material fast and accurate, reduces the time of manual adjustment, and thus improves the efficiency of the overall grinding operation. Through the precise matching of the bidirectional screw 64 and the slide plate 65, the synchronous and stable movement of the clamping plate 62 is achieved, and the stability and reliability of the clamping are effectively guaranteed. When the stainless steel material needs to be fixed on the grinding table 1, the drive motor 66 is first started, and the drive motor 66 drives the bidirectional screw 64 to rotate. Since the two sides of the two-way screw rod 64 have opposite thread directions, when it rotates, the two slide plates 65 will move in opposite thread directions, driving the clamping plate 62 to approach the stainless steel material synchronously. As the clamping plate 62 gradually approaches, the stainless steel material is firmly clamped between the two. When the required clamping force is reached, the drive motor 66 is turned off and the grinding operation can be started. After the grinding is completed, the drive motor 66 is started again to reverse, so that the clamping plate 62 is separated and the stainless steel material is released.

[0029] More specifically, in order to prevent the stainless steel from slipping with the clamping plate 62, an anti-slip tooth 621 is processed at one end of the clamping plate 62 close to the stainless steel. The anti-slip tooth 621 is a series of tiny and dense protrusions or grooves, which are carefully processed on the inner surface of the clamping plate 62, that is, the end that is in direct contact with the stainless steel material. These anti-slip teeth 621 can be regular sawtooth shapes, wavy shapes or other shapes that can increase friction. By increasing the roughness of the contact surface, the anti-slip teeth 621 can significantly increase the friction between the clamping plate 62 and the stainless steel material, thereby effectively preventing slippage caused by vibration or impact during the grinding process. The design of the anti-slip teeth 621 enables the clamping plate 62 to grasp the stainless steel material more firmly, and maintain a stable clamping state even under high-speed grinding or strong impact, greatly improving the safety and efficiency of the operation. Before the grinding operation begins, the operator places the stainless steel material on the grinding table 1 and starts the drive motor 66. As the bidirectional screw 64 rotates, the clamping plate 62 is gradually brought closer to the stainless steel material by the slide plate 65. When the anti-skid teeth 621 of the clamping plate 62 come into contact with the stainless steel material, due to the special design of the anti-skid teeth 621, they can quickly and firmly grasp the surface of the material to form a stable clamping force. At this time, even if the grinding device body 2 starts to work and generates vibration or impact force, the stainless steel material can be firmly fixed between the clamping plates 62, thereby ensuring the smooth progress of the grinding operation.

[0030] Furthermore, in order to facilitate wiping the polished stainless steel surface: the polishing table 1 is also provided with a wiping structure 7 for wiping the stainless steel surface, which includes a fixed shell 71, a wiping cloth 72 fixedly mounted at the lower end of the fixed shell 71, a fixed plate 73 fixedly mounted at both ends of the fixed shell 71, a guide plate 74 fixedly mounted at both ends of the Y-axis moving mechanism 43, a guide rod 75 plugged into the guide plate 74 and fixedly connected to the upper end of the fixed plate 73, a baffle 76 fixedly connected to the top of the guide rod 75, and a spring 77 sleeved on the guide rod 75 corresponding to the fixed plate 73 and the guide plate 74. Among them, the wiping cloth 72 needs to be made of soft and wear-resistant materials, such as clean cloth, paper towel or special wiping material, so that it can remove stains without damaging the stainless steel surface during the wiping process, and avoid using cleaning agents containing corrosive or abrasive components to avoid damaging the surface of the stainless steel plate. The main function of the spring 77 is to provide a buffer and reset function. When the wiping structure 7 contacts the stainless steel surface and applies a certain pressure, the spring 77 can absorb part of the impact force and keep the wiping cloth 72 in close contact with the stainless steel surface; when the wiping is completed, the spring 77 can push the wiping structure 7 to automatically reset to the initial position. The wiping structure 7 can automatically wipe the stainless steel surface after the grinding is completed to remove the residual grinding chips and stains, and ensure the cleanliness and flatness of the stainless steel surface. After the grinding operation is completed, the Y-axis moving mechanism 43 drives the wiping structure 7 to move above the stainless steel surface along the Y-axis direction according to the preset program or manual instruction. As the Y-axis moving mechanism 43 continues to move, the wiping structure 7 gradually approaches the stainless steel surface and applies a certain pressure. At this time, the wiping cloth 72 is in close contact with the stainless steel surface and starts the wiping action. During the wiping process, the spring 77 provides the necessary buffer and reset force to ensure the stability and uniformity of the wiping effect. When the wiping is completed, the spring 77 cooperates with the Y-axis moving mechanism 43 to drive the wiping structure 7 to automatically reset to the initial position and wait for the next use.

[0031] In addition, the present application also provides a fixed bracket of a stainless steel polishing and grinding device, and the fixed bracket includes the above-mentioned grinding device.

[0032] The above is only a preferred specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes according to the technical solution and concept of the present application within the technical scope disclosed in the present application, which should be covered by the protection scope of the present application.
