Technical Field
[0001] This utility model relates to the field of skeleton processing technology, and in particular to a deburring device for processing automotive seat skeletons. Background Technology
[0002] The car seat frame is a crucial load-bearing structure of a car seat, typically made of metal profiles through welding, stamping, and other processes. It plays a vital role in supporting the overall seat structure and ensuring passenger safety and comfort. As the automotive industry continues to demand higher standards of vehicle safety and comfort, the requirements for processing precision and surface quality in the design and manufacturing of car seat frames are becoming increasingly stringent.
[0003] During the manufacturing process of automotive seat frames, especially after welding or cutting, burrs and flash often appear on their edges or connecting parts. If these burrs are not removed promptly, they can not only affect subsequent assembly processes but also pose safety hazards such as cuts to operators. Therefore, burr removal is a crucial step in automotive seat frame manufacturing, and its quality directly impacts the overall performance of the product and production safety. Particularly in the core process of deburring complex structural parts, existing grinding equipment is increasingly revealing a series of significant limitations and technical problems.
[0004] Specifically, utility model patent CN218254308U discloses a deburring device comprising a worktable, mounting slot, rotating assembly, first electric telescopic rod, clamping assembly, fixing frame, grinding assembly, protective mechanism, hydraulic rod, dust extraction hood, conduit, air pump, and storage tank. This device uses an electric push rod to drive a slider to slide on a guide rod, causing the clamping block to clamp the workpiece, achieving automatic clamping. The hydraulic rod also drives the storage tank downwards, coordinating with the air pump to suck burrs and dust generated during grinding into the storage tank, effectively preventing burr splashes from affecting the environment and operators, and improving the safety and automation of the grinding process.
[0005] However, in practical applications, it was found that the equipment suffers from a problem where the grinding components cannot move flexibly. All grinding operations rely on the movement of the workpiece to achieve contact processing in different areas. Because automotive seat frames are large and heavy, movement is difficult and time-consuming, resulting in low grinding efficiency and inconvenient operation, directly leading to reduced grinding efficiency and increased operational complexity. Therefore, to address the many shortcomings of existing technologies, we urgently need an innovative deburring equipment for automotive seat frame processing to solve these problems.

[0022] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.
[0023] Please see Figure 1-5 A deburring and polishing device for processing automotive seat frames includes a frame 1, and a support frame 2 slidably connected to the inner side of the frame 1. Rotating rods 5 are rotatably connected to both sides of the inner side of the support frame 2, and polishing plates 6 are fixedly connected to opposite ends of the two rotating rods 5. A dual-axis motor 19 is bolted to one side of the outer wall of the support frame 2, and connecting rods 17 are provided on both sides of the support frame 2. One end of each connecting rod 17 is connected to the output shaft of the dual-axis motor 19. One end of each connecting rod 17 is wound around one end of each rotating rod 5 via a belt 12. A screw 7 is rotatably connected to one side of the inner side of the frame 1, and a drive motor 10 is bolted to one side of the top of the frame 1. The top end of the screw 7 penetrates the top of the frame 1 and is connected to the output shaft of the drive motor 10. One end of the screw 7 is threadedly connected to a nut seat 16, and one side of the nut seat 16 is fixedly connected to one side of the support frame 2.
[0024] First, the car seat frame material to be deburred is placed between two grinding plates 6, ensuring it is within the reasonable working range of the support frame 2. Then, the dual-axis motor 19, fixed to one side of the outer wall of the support frame 2, is activated. The output shaft of this motor drives two connecting rods 17 to rotate synchronously via a transmission connection. One end of each connecting rod 17 is connected to one end of each of the two rotating rods 5 via a belt 12, thus achieving effective power transmission. This causes the two rotating rods 5 to rotate synchronously, thereby driving the two grinding plates 6 fixed at their bottom ends to begin high-speed rotation, entering the grinding working state. Simultaneously, to achieve automatic grinding of different height areas of the entire car seat frame material, the drive motor 10, installed on one side of the top of the frame 1, is activated. The output shaft of 10 drives the screw 7, which passes through the top of the frame 1 and is connected to it, to rotate. Since one end of the screw 7 is connected to the nut seat 16 by a threaded connection, and one side of the nut seat 16 is fixedly connected to one side of the bearing frame 2, when the screw 7 rotates, it can drive the nut seat 16 to move up and down along the length of the screw 7, thereby driving the bearing frame 2 and the grinding components on it to slide up and down along the inner side of the frame 1. In this way, the rotating grinding plate 6 can perform continuous grinding operations along the height direction of the car seat frame material under the drive of the bearing frame 2, and complete the efficient removal of defects such as burrs and flash on the surface of the workpiece. The whole process does not require frequent manual adjustment or movement of the heavy car seat frame material, thus realizing automated and continuous grinding operation.
[0025] Furthermore, a side groove 18 is provided on one side of the support frame 2, and pulleys 11 are sleeved on one end of the two connecting rods 17 and one end of the two rotating rods 5. The two pulleys 11 on the same side of the four pulleys 11 are connected by belts 12. The two belts 12 pass through the side wall of the support frame 2 through the side groove 18. This design allows the dual-axis motor 19 to effectively transmit power to the rotating rods 5, ensuring the stable rotation of the grinding plate 6. This not only enhances the stability and efficiency of the transmission system, but also reduces energy loss caused by friction or slippage, and improves the continuity and reliability of the grinding work.
[0026] Furthermore, a fixed frame 20 is provided on the outer side of the dual-axis motor 19, and one side of the fixed frame 20 is fixedly connected to the outer wall of the bearing frame 2. One side of the fixed frame 20 is fixedly connected to one side of the nut seat 16. Slide rods 14 are fixedly connected to both sides of the frame 1, and a sliding sleeve 15 is fitted on one end of each slide rod 14. One side of each sliding sleeve 15 is fixedly connected to one side of the nut seat 16. This provides additional support and guidance for the bearing frame 2 when it moves up and down. This not only increases the overall structural stability of the device, but also effectively reduces wear or loosening caused by long-term use. It ensures that the bearing frame 2 moves smoothly and accurately along the predetermined path during the grinding process, thereby improving grinding accuracy and safety.
[0027] Furthermore, a top groove 8 is provided on the top of the frame 1, and clamping plates 9 are rotatably connected to the inner sides of the top groove 8 via torsion spring shafts. A bottom groove 13 is provided on the inner bottom of the frame 1. When placing automotive seat frame plates, the position of the clamping plates 9 can be adjusted to accommodate workpieces of different sizes, providing more stable positioning support and ensuring that the workpiece will not shift during the grinding process, thereby improving grinding quality and work efficiency.
[0028] Furthermore, sliders 3 are fixedly connected to both sides of the support frame 2, and both sliders 3 are slidably connected to the side wall of the frame 1 through the sliding groove 4. The sliders 3 fixedly connected to both sides of the support frame 2 and the sliding groove 4 slidably connected to the side wall of the frame 1 ensure the smoothness and directionality of the support frame 2 when moving up and down along the inner side of the frame 1, prevent the support frame 2 from deviating or shaking, ensure the consistency of the contact between the grinding component and the workpiece surface, and help improve the consistency of grinding effect and quality.
[0029] Furthermore, the bottom end of the screw 7 is rotatably connected to the inner bottom of the frame 1 via a rotating shaft, and the top end of the screw 7 passes through the top of the frame 1 via a bearing sleeve. One end of each of the two rotating rods 5 is rotatably connected to the inner wall of the bearing frame 2 via a rotating shaft. This enables the nut seat 16 to move smoothly up and down along the screw 7 when the drive motor 10 drives the screw 7 to rotate, while the rotating rods 5 can rotate freely inside the bearing frame 2 without affecting the movement of the bearing frame 2. This not only optimizes the power transmission efficiency of the entire equipment but also extends the service life of the equipment and reduces maintenance costs.
[0030] In summary:
[0031] First, the car seat frame material to be deburred is placed in the top groove 8 of the frame 1, and the workpiece is initially positioned by clamping plates 9 connected by torsion spring shafts on both sides. Simultaneously, the bottom groove 13 on the inner bottom of the frame 1 provides support and clearance for the material, ensuring stability and preventing displacement during the deburring process. Then, the dual-axis motor 19, fixed to one side of the outer wall of the support frame 2, is activated. This motor is bolted to the support frame 2, and a fixing frame 20 is provided externally. One side of the fixing frame 20 is fixedly connected to both the outer wall of the support frame 2 and one side of the nut seat 16 to enhance structural stability. The output shaft of the dual-axis motor 19... The two connecting rods 17 rotate synchronously. One end of the connecting rod 17 is connected to the output shaft of the dual-axis motor 19 through a transmission structure, and the other end is connected to the pulley 11 on the rotating rod 5 through a belt 12. The belt 12 passes through the side groove 18 opened on the support frame 2 and penetrates its side wall, thereby realizing the effective transmission of power. The two rotating rods 5 are respectively rotatably connected to the inner sides of the support frame 2 and connected to the inner wall of the support frame 2 through a rotating shaft, so that they can rotate smoothly, thereby driving the two grinding plates 6 fixed at their ends to rotate at high speed and enter the grinding state. At the same time, in order to realize the grinding components at different heights Automatic position adjustment is initiated by activating the drive motor 10 mounted on one side of the top of the frame 1. This motor is bolted to the top of the frame 1, and its output shaft drives a screw 7, which passes through the top of the frame 1 and is fixed by a bearing sleeve, to rotate. The bottom end of the screw 7 is rotatably connected to the bottom inner side of the frame 1 via a rotating shaft, forming a stable rotation fulcrum. A nut seat 16 is screwed onto the screw 7. One side of the nut seat 16 is fixedly connected to one side of the support frame 2, and the other side is slidably engaged with sliding rods 14 fixed on both sides of the frame 1 via a sliding sleeve 15, providing good guidance and stability for the support frame 2 during vertical movement. As the screw 7 rotates, the nut seat 16 moves along... The screw 7 moves up and down along its length, causing the bearing frame 2 and the grinding components on it to slide up and down along the inner side of the frame 1. The bearing frame 2 is also equipped with sliders 3 on both sides, which are slidably connected to the side wall of the frame 1 through the groove 4, further improving the smoothness and accuracy of the bearing frame 2 during movement. In this way, the two high-speed rotating grinding plates 6 can perform continuous grinding operations along the height direction of the car seat frame material under the drive of the bearing frame 2, and efficiently remove defects such as burrs and flash from the workpiece surface. The whole process does not require frequent manual adjustment or movement of the heavy car seat frame material, realizing automated and continuous grinding operation.The power transmission system, consisting of a dual-axis motor 19, connecting rod 17, pulley 11, belt 12, and rotating rod 5, enables the synchronous high-speed rotation of the two grinding plates 6. This not only improves deburring efficiency but also enhances the uniformity and consistency of grinding quality, solving the problem of uneven grinding caused by unstable power transmission in existing technologies. Secondly, the lifting mechanism, consisting of a drive motor 10, screw 7, nut seat 16, slide rod 14, and sliding sleeve 15, enables automatic vertical displacement of the grinding components. This effectively avoids the inefficiency and safety hazards associated with manually moving heavy objects, significantly improving adaptability to complex structures and reducing the labor intensity of operators. Thirdly, the sliders 3 on both sides of the support frame 2 work in conjunction with the grooves 4 on the side walls of the frame 1, allowing the support frame 2 to move vertically... Maintaining good guidance and operational stability during movement prevents uneven grinding surfaces or workpiece damage caused by shaking, thereby further ensuring grinding accuracy. In addition, the side groove 18 on the support frame 2 and the through-belt structure of the belt 12 effectively optimize the power transmission path, improve the stability and reliability of the transmission system, and reduce energy loss. The fixed frame 20 not only strengthens the connection between the dual-axis motor 19 and the support frame 2, but also enhances the rigidity of the overall structure through its connection with the nut seat 16, extending the service life of the equipment. Finally, the clamping plate 9 at the top of the frame 1 achieves self-adaptive clamping through a torsion spring shaft. Combined with the design of the bottom groove 13, it can flexibly adapt to different sizes of automotive seat frame plates, improving the versatility of the equipment while also enhancing the safety and stability of the grinding process.
