Description

Technical Field

[0001] The invention relates to the field of grinding, and in particular to an automatic grinding system for seat bars. Background Art

[0002] In the field of seat manufacturing, especially in the processing and surface treatment of seat components, traditional processes often cannot meet the requirements of high precision, high efficiency, high adhesion and low temperature processing for seat bars. The manufacture of seats usually involves precision grinding of seat bars to ensure their surface smoothness, adhesion and overall quality. Traditional grinding methods have some limitations, such as the inability to effectively form surface micro-depression and texture, which reduces the adhesion of subsequent coating processes. At the same time, excessive heat may be generated during the traditional grinding process, affecting the stability of the workpiece and equipment, and thus affecting the grinding quality. There are some improvements in the prior art, but there are still some problems. For example, the patent number CN219666154U discloses a grinding device for sheet metal processing, which has the following deficiencies in the field of grinding: 1. The fixed grinding method is adopted, which lacks sufficient flexibility to adapt to seat bars of different shapes and sizes, resulting in insufficient adaptability of the production line. 2. Due to the limitations of the surface treatment method, the surface roughness of the seat bar cannot reach the optimal level, affecting the adhesion of the subsequent coating. 3. During the grinding process, mechanical friction and grinding will cause friction heat on the workpiece surface and the grinding head, which will cause local high temperature. Excessive heat accumulation will damage the workpiece and grinding equipment and reduce the efficiency of the entire processing system. Summary of the invention

[0003] 1. Technical issues to be solved

[0004] In view of the deficiencies of the prior art, the present invention aims to provide an automatic grinding system for seat bars, which solves the problems existing in the prior art. By introducing the design of a movable grinding mechanism, the grinding cylinder can be flexibly adjusted to adapt to workpieces of different shapes, thereby improving the adaptability of the entire system to different seat components. And through the synergistic effect of the fixed grinding mechanism and the movable grinding mechanism, the specific design of the first grinding cylinder and the second grinding cylinder is adopted to form tiny depressions and textures on the surface, which helps to form a certain texture on the surface of the seat bar and improve the adhesion of the subsequent coating. And through the spiral texture of the grinding cylinder, a heat dissipation channel is formed, and the design of the multi-layer transmission structure in the fixed grinding mechanism and the dividing strips of the movable grinding mechanism play a role in guiding and optimizing heat transfer in the heat dissipation channel, which not only helps to effectively dissipate the heat generated by friction heat, but also reduces the grinding temperature, prevents excessive heat accumulation, and ensures the stable operation of the system.

[0029] The following will be combined with the attached examples of the present invention Figure 1-10 The technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0030] The present invention provides a technical solution: an automatic grinding system for seat bars, including an automatic grinding system for seat bars, including a frame 1, a fixed grinding mechanism 2 is fixed on the upper rear side of the frame 1, a movable grinding mechanism 3 is fixed on the upper front side of the frame 1, a loading platform 4 is arranged on the left side of the frame 1, a unloading platform 5 is arranged on the right side of the frame 1, and a conveying mechanism 6 is arranged between the loading platform 4 and the unloading platform 5; the frame 1 is a supporting structure of the whole system, which is used to fix and support components of other grinding systems. It provides a stable foundation for the system and ensures the correct installation and alignment of each component. The fixed grinding mechanism 2 is located at the upper rear side of the frame 1, and its function is to perform directional and fixed position grinding on the seat bars, and provide grinding consistency and accuracy. The movable grinding mechanism 3 is located at the upper front side of the frame 1, and its function is to perform flexible and adjustable position grinding on the seat bars, and increase the flexibility and adaptability of the system. The loading platform 4 and the unloading platform 5 are respectively located on the left and right sides of the frame 1, and are used to place the seat bars. The loading platform is used to feed the seat bars into the grinding system, and the unloading platform is used to receive the seat bars that have been polished. They provide support and positioning for the seat bars during the conveying process. The inlet and outlet positions of the loading platform 4 and the unloading platform 5 are provided with motors to drive the movement of the seat bars. The conveying mechanism 6 is located between the loading platform 4 and the unloading platform 5. Its function is to transfer the seat bars from the loading platform to the unloading platform to ensure the smooth transfer of the seat bars during the grinding process.

[0031] The fixed grinding mechanism 2 includes a first grinding motor 201 fixed to the upper end of the frame 1, a mounting plate 202 fixed to the left side of the frame 1, a rotating ball bearing 203 embedded in the middle of the right side of the mounting plate 202, a transmission shaft 204 axially connected between the first grinding motor 201 and the rotating shaft bearing 203, a fastening sleeve 205 sleeved on the transmission shaft 204 and the output shaft of the first grinding motor 201, a sleeve tube 206 fixed to the left side of the transmission shaft 204, a first grinding tube 207 fixed on the outer contour of the sleeve tube 206, and a stabilizing plate 208 embedded in the left part of the first grinding tube 207. The first grinding motor 201 is the main power source of the mechanism, and the first grinding motor provides the necessary power to drive the grinding process. Through the output shaft, it transmits the rotational force to the transmission shaft 204, so that the entire grinding mechanism starts to operate. The mounting plate 202 is the base of the first grinding motor and other mechanism components, and is fixed to the left side of the frame 1. It provides stable support and position to ensure that the overall structure of the grinding mechanism is firm. The ball bearing 203 is embedded in the middle of the right side of the mounting plate 202. The ball bearing 203 is responsible for supporting the rotational movement of the transmission shaft 204, reducing the friction force and allowing the transmission shaft to rotate more freely. The transmission shaft 204 is a key component connecting the first grinding motor 201 and the ball bearing 203, and is responsible for transmitting the rotational force of the motor to the grinding mechanism. It is axially connected between the first grinding motor and the ball bearing, and drives the operation of the entire mechanism through rotation. The fastening sleeve 205 is sleeved on the transmission shaft 204 and the output shaft of the first grinding motor 201. The function of the fastening sleeve is to ensure the effective connection between the transmission shaft and the motor output shaft so that the rotational force can be smoothly transmitted.

[0032] An arc-shaped interlocking tooth 2041 is provided on the left side of the transmission shaft 204 near the position of the sleeve tube 206. Its main function is to interlock with the transmission tooth 2061 of the sleeve tube 206 to form a transmission mechanism. When the transmission shaft 204 rotates, the arc-shaped interlocking tooth 2041 interlocks with the transmission tooth 2061 in the sleeve tube 206, so that the rotational force of the transmission shaft can be effectively transmitted to the sleeve tube 206, thereby driving the rotation of the first grinding tube 207. This interlocking mechanism ensures the reliability and efficiency of the transmission, so that the entire grinding mechanism can work in coordination. The sleeve tube 206 is fixed on the left side of the transmission shaft 204, and the first grinding tube 207 is installed on the outer contour of the sleeve tube 206. The first grinding tube is the tool that actually performs the grinding task. It rotates during the grinding process and contacts the surface of the seat bar to achieve precise grinding. The stabilizing plate 208 is embedded in the left part of the first grinding cylinder 207. The function of the stabilizing plate is to provide additional support and stability to ensure that the first grinding cylinder maintains the correct position and direction during operation.

[0033] The sleeve tube 206 is in a stepped cylindrical shape, and a transmission tooth 2061 is arranged inside the sleeve tube 206. The outer contour of the largest end of the sleeve tube 206 is arrayed with a trapezoidal meshing tooth 2062. These teeth are tightly meshed with the first grinding tube 207 during the grinding process of the seat bar material, ensuring stability and efficiency during grinding. The design of the meshing tooth 2062 helps to provide additional transmission force and make the entire grinding mechanism more solid. Through such a design, the arc-shaped interlocking tooth 2041 and the transmission tooth 2061 of the sleeve tube 206 work together with the meshing tooth 2062 to form a reliable transmission structure, so that the power can be effectively transmitted to the grinding mechanism, thereby realizing efficient grinding of the seat bar material. An interlocking mechanism is formed between the arc-shaped interlocking tooth 2041 and the transmission tooth 2061 of the sleeve tube 206. In this contact area, due to the shape of the teeth and the interlocking method, the surface contact integral is relatively large. Compared with flat contact, the contact surface between the arc-shaped interlocking teeth and the transmission teeth is more complex, so that the transferred heat can be more evenly distributed on these contact surfaces. The shape design of the arc-shaped interlocking teeth and the transmission teeth may make it easier for the contact surfaces to adapt to each other's shapes and form a closer contact. This helps to improve the efficiency of heat transfer because the advantage of the surface shape can reduce gaps and make heat transfer faster.

[0034] The first grinding cylinder 207 is cylindrical, and a mounting tooth 2071 arranged in an array around the center of the circle is provided on the right side, and a clockwise spiral grinding pattern 2072 is provided on the outer contour of the first grinding cylinder 207. The mounting tooth 2071 arranged in an array around the center of the circle is located on the right side of the first grinding cylinder 207, and is used to be fixed on the sleeve cylinder 206 to ensure its correct position and stability. The clockwise spiral grinding pattern 2072 is located on the outer contour of the first grinding cylinder 207, and is used to apply a certain force and friction on the surface of the seat bar. This helps to improve the grinding effect and increase the contact area with the surface of the seat bar, so as to more effectively remove the unevenness and defects of the surface. It also has the following functions: Enhancement of grinding effect: The clockwise spiral grinding pattern 2072 can guide the seat bar to pass through the first grinding cylinder 207 in a rotating manner during the grinding process. This spiral shape can lead to a more uniform grinding effect, which helps to avoid leaving obvious marks or uneven grinding marks on the surface of the seat bar. Formation of surface texture: Through the clockwise spiral grinding pattern 2072, a certain texture can be formed on the surface of the seat bar. These tiny depressions and textures may help increase the adhesion of the coating and increase the roughness of the seat bar surface, thereby improving the adhesion effect during the subsequent spraying process. Directional grinding: The spiral grinding pattern 2072 will give the grinding direction a certain direction. Such directional grinding helps to form a consistent texture and surface texture on the seat bar, providing a more uniform foundation for subsequent coating and surface treatment.

[0035] The spiral pattern creates a heat dissipation channel. During grinding, the abrasive chips are discharged along the spiral pattern, creating a ventilation effect. This helps to carry heat away from the surface of the workpiece and the grinding head, making it easier to dissipate into the surrounding environment. The spiral pattern design increases the total volume of the grinding head contact surface with the workpiece, providing more surface area for heat dissipation. This design increases the contact area with the surrounding air, which helps to transfer heat more effectively. The design of the heat dissipation channel helps to achieve uniform temperature distribution. In this way, the surface of the workpiece does not have concentrated hot spots, but can be cooled more evenly. Temperature uniformity helps to avoid problems caused by local overheating.

[0036] Through the combined design of the transmission shaft 204, the fastening sleeve 205, the sleeve 206 and the first grinding cylinder 207, a multi-layer transmission system is generated, which can effectively transfer power from one level to another, thereby improving the efficiency of the entire transmission system. The gears or meshing structures of each transmission level can effectively transfer power, reduce energy loss, and make the rotation of the grinding cylinder smoother. In the multi-layer transmission system, the gears or structures that mesh with each other can produce a self-stabilizing effect during movement. This helps to reduce the vibration and impact generated by the system during movement and improve the stability of the entire system. In general, the design of the arc-shaped interlocking teeth and transmission teeth helps to improve the stability of the system, reduce vibration and vibration during movement, and reduce the noise level. Such a design enables the grinding system to operate in an efficient, stable and low-noise state, ensuring the smooth progress of the grinding process.

[0037] In summary, the fixed grinding mechanism effectively converts the rotation of the power source into the grinding force of the seat bar through the synergistic effect of the above components, ensuring the stability and accuracy of the grinding process. Each component plays a key role in the mechanism and works together to achieve efficient seat bar grinding.

[0038] The movable grinding mechanism 3 includes a fixed frame 301 fixed to the front side of the upper end of the frame 1, a guide rail 302 is symmetrically arranged on the upper end of the fixed frame 301, a mounting plate 303 is slidably connected to the upper end of the guide rail 302, a mounting frame 304 is fixed to the left side of the mounting plate 303, a second grinding motor 305 is fixed to the left side of the mounting frame 304, a second sleeve 306 is fixed to the output shaft of the second grinding motor 305, a second transmission shaft 307 is fixed to the right side of the second sleeve 306, a second grinding cylinder 308 is axially connected to the outer contour of the second transmission shaft 307, a bearing 309 is connected to the end of the second transmission shaft 307, a motor fixing seat 310 is arranged on the right side of the fixed frame 301, a push rod motor 311 is arranged on the right side of the motor fixing seat 310, and the output shaft end of the push rod motor 311 is fixedly connected to the mounting plate 303. The fixed frame 301 is fixed to the front side of the upper end of the frame 1 to provide a solid support for the entire movable grinding mechanism 3. It ensures the stability and reliability of the movable grinding mechanism and assumes the basic structural function of connecting other components. The guide rail 302 is located at the upper end of the fixed frame 301, and the mounting plate 303 is connected to the guide rail by sliding. This design allows the mounting plate to slide along the guide rail in the horizontal direction, realizing the front and rear adjustment of the grinding head. The mounting frame 304 is mounted on the mounting plate 303 to provide support for the second grinding motor 305 and related components. It is fixed with the second grinding motor 305 on the left side, becoming the basic support of the entire grinding mechanism. The second grinding motor 305 is mounted on the mounting frame 304 and is the power source of the entire system. Through the rotational movement on the output shaft, it drives the second sleeve 306, thereby rotating the second transmission shaft 307 and pushing the second grinding cylinder 308 for grinding. The second sleeve 306 is fixed on the output shaft of the second grinding motor 305, and transmits the rotational movement of the motor to the second transmission shaft 307. The second transmission shaft 307 transmits power to the second grinding cylinder 308 through the connection on the outer contour. The bearing 309 on the shaft ensures smooth and reliable transmission. The second grinding cylinder 308 is a cylindrical structure, which is driven by the second grinding motor 305 to grind the seat bar. It may have a specific surface design to achieve the desired grinding effect. The motor fixing seat 310 is located on the right side of the fixing frame 301 and is used to install the push rod motor 311. The push rod motor 311 is fixedly connected to the mounting plate 303 through the end of the output shaft, and is used to control the movement of the movable grinding mechanism 3 in the horizontal direction.

[0039] The outer contour of the second grinding barrel 308 is provided with a second grinding pattern 3081 in a counterclockwise spiral shape. The clockwise spiral grinding pattern 2072 of the first grinding barrel 207 and the counterclockwise spiral grinding pattern 3081 of the second grinding barrel 308 are combined together. The combination of the two grinding barrels can achieve comprehensive grinding coverage, ensuring that the entire surface of the seat bar is fully processed. The combination of clockwise and counterclockwise spiral patterns allows the grinding head to cover the surface of the workpiece more comprehensively, ensuring the uniformity of the overall grinding effect. The design of the surface pattern helps to improve the adhesion of the coating. The tiny depressions and textures created by the first grinding barrel 207, combined with the patterns of the second grinding barrel 308, provide more favorable surface conditions for the subsequent coating process and improve adhesion.

[0040] A shielding bin 3041 is provided on the right side of the mounting frame 304, and an arc-shaped dividing strip 3042 is provided inside the shielding bin 3041. During the grinding process, grinding chips (small particles that are ground off) may be generated on the surface of the seat bar. The shielding bin 3041 can act as an isolation space to prevent the grinding chips from entering other parts of the system. The arc shape of the dividing strip 3042 helps to guide the grinding chips to flow along the curve and prevent them from directly entering the interior of the system. The shielding bin 3041 prevents the grinding chips from splashing into the surrounding environment, which helps to maintain the cleanliness of the grinding area. This is important for the safety of operators and the normal operation of the system, because a clean working environment can reduce potential safety risks, while preventing grinding chips from entering other equipment or mechanical parts and reducing mechanical wear. The arc position of the dividing strip 3042 corresponds to the counterclockwise spiral pattern on the second grinding cylinder 308, which can form a continuous channel, which helps to more effectively remove the heat generated during the grinding process. This can improve the heat dissipation effect of the system and help maintain a suitable temperature during the grinding process. The design of the heat dissipation channel and the dividing strip helps to reduce the heat generated by friction. By better removing heat, the effects of friction on the system can be reduced, improving the efficiency and stability of the entire grinding system.

[0041] The conveying mechanism 6 includes a mounting base 601, a chuck 602 is symmetrically arranged at the upper end of the mounting base 601, a limiting guide plate 603 is fixed inside the chuck 602, a support plate 604 is arranged at the lower end of the limiting guide plate 603, a conveying track 605 is fixed on the right side of the mounting base 601, and a driving device 606 is arranged at the middle lower end of the conveying track 605. The chuck 602 is a component used to fix and clamp the seat bar. Its role in the conveying mechanism is to ensure that the seat bar can be firmly fixed during the conveying process to avoid unnecessary shaking and instability. The limiting guide plate 603 is located on the inner side of the chuck 602, and its role is to limit the seat bar to ensure that it moves along the specified path during the conveying process. This helps to maintain the stable conveying of the seat bar and prevent it from deviating from the track. The support plate 604 is used to provide support for the seat bar, and the conveying track 605 is a guide channel for the seat bar to be conveyed in the system. It ensures that the seat bar moves along the specified path and remains stable during the conveying process. The driving device 606 is responsible for providing power to the conveying track, and the seat bar is driven by the motor to move along the track. A grinding notch 6031 is provided in the middle of the limiting guide plate 603. The existence of the grinding notch can provide sufficient space for the grinding head while the seat bar is being conveyed, ensuring the smooth progress of the grinding operation. The notch provides a channel for the grinding head to more easily contact and process specific areas of the seat bar. Grinding chips are generated during the grinding process, and the grinding notch allows these grinding chips to be discharged along the notch to prevent them from accumulating on the guide plate. This helps to maintain a clean working environment and reduce the adverse effects of grinding chips on the system. In general, the conveying mechanism is designed to achieve efficient, stable and controllable transmission of seat bars in the grinding system. Through the synergistic effect of clamping, limiting, supporting and pushing functions, the conveying mechanism helps to ensure that the seat bar can move in a controlled manner during the grinding process and reach the desired position and direction.

[0042] Working principle:

[0043] In the actual working process, batches of seat bars are placed on the loading platform 4, and the workpiece is accurately guided to the grinding position through the guiding effect of the limiting guide plate 603 on the conveying mechanism 6. After the workpiece reaches the grinding position, it is located between the fixed grinding mechanism 2 and the movable grinding mechanism 3. The second grinding cylinder 308 on the movable grinding mechanism 3 is extended through the screw rod of the push rod motor 311, and adaptively contacts the workpiece to ensure tight and stable positioning. The first grinding motor 201 and the second grinding motor 305 are started, and the first grinding cylinder 207 and the second grinding cylinder 308 are driven by the transmission shaft to grind the workpiece. The design of these two grinding cylinders allows them to form specific textures during the grinding process, namely the grinding lines 2072 on the first grinding cylinder 307 and the second grinding lines 3081 on the second grinding cylinder 308. The design purpose of the grinding lines and the second grinding lines is to form tiny depressions and textures on the surface of the seat bars. These specific surface features are carefully designed to improve the adhesion of the coating and increase the roughness of the seat bar surface, thereby improving the adhesion effect during the subsequent spraying process. And the spiral design not only helps to form the texture, but also effectively reduces the temperature during the grinding process. This helps to avoid overheating and ensures that the seat bar and the grinding head work in the appropriate temperature range. After grinding is completed, the workpiece is fed into the unloading table with the entry of the next workpiece, and the entire processing process is completed.
