[0004] In related technologies, workers need to clamp and punch holes in the front bracket, which is usually done using a stamping machine. The above-mentioned utility model uses a stamping head to press down the front bracket of the passenger side, and then guides it through a guide column. When the front bracket of the passenger side is fixed, the workpiece is punched. However, before stamping, the workpiece needs to be installed inside the guard rod, which guides the workpiece. But to insert the guard rod into the workpiece, holes need to be pre-drilled in the workpiece, which increases the workload and makes the punching efficiency of the workpiece low.

[0005] Therefore, it is necessary to provide a clamping mechanism for machining the front passenger side bracket of an automobile to solve the above-mentioned technical problems. Utility Model Content

[0006] To address the issue that when fixing the front passenger seat bracket, punching is performed on the workpiece, but before punching, the workpiece needs to be installed inside the guard rod, which guides the workpiece, pre-drilling holes is required to insert the guard rod into the workpiece, thus increasing the workload and reducing the punching efficiency, this utility model provides a clamping mechanism for processing the front passenger seat bracket of an automobile.

[0007] This utility model provides a clamping mechanism for processing a front passenger seat bracket for automobiles, comprising: a base, a plurality of support columns fixedly connected at equal intervals above the base, a guide column fixedly connected to the upper end of each of the plurality of support columns, a support plate fixedly connected to the upper end of each of the plurality of guide columns, and a movable plate movably disposed on the surface of each of the plurality of support columns.

[0008] A cylinder is fixedly mounted below the support plate. A pressure rod is driven and connected to the lower output end of the cylinder. A clamping block is fixedly inserted into the surface of the pressure rod. Two limiting components are fixedly connected inside the movable plate, with the two limiting components located on opposite sides of the pressure rod.

[0009] The bracket body is movably disposed above the base and below the clamping block. A base is fixedly connected above the base, and the base is located around the bracket body.

[0010] Preferably, the base has a receiving groove and a guiding groove inside, the guiding groove and the receiving groove are connected on one side, one end of the guiding groove extends downward at an angle, and the bracket body is located above the receiving groove.

[0011] Preferably, a plurality of limiting posts are fixedly connected to the top of the base, one end of the plurality of limiting posts penetrates through the clamping block, and the plurality of limiting posts are respectively located on both sides of the two limiting components.

[0012] Preferably, the limiting component includes a fixing block fixedly connected to the movable plate, a guide rod slidably inserted inside the fixing block, the lower end of the guide rod being fixedly connected to the clamping block, a threaded rod being threadedly connected to the upper end of the guide rod, and a turntable being fixedly connected to the upper end of the threaded rod, the turntable rotating above the fixing block.

[0015] Compared with related technologies, the clamping mechanism for processing the front passenger seat bracket of an automobile provided by this utility model has the following advantages:

[0016] 1. When punching the bracket body, the worker places it on top of the base. The bracket body's shape fits snugly against the inner wall of the base, reducing movement and improving stability during punching. A clamping block secures the support plate above the base, and a cylinder is fixed below the support plate. When the cylinder is activated, it drives the pressure rod downwards. The pressure rod has an outward-protruding boss in the middle. A movable plate is positioned above the boss, and its lower part fits against it. The movable plate slides downwards along the surface of the support column, causing two internal limiting components to descend. These components support the clamping block below, which then presses against the bracket body, improving the fit between the bracket body and the base and enhancing stability during punching. The pressure rod presses downwards, and a punch is fixed to the lower end of the pressure rod through the clamping block. The punch punches the bracket body, increasing the efficiency and stability of the clamping process.

[0017] 2. The turntable rotates above the fixed block. The limiting component fixes the clamping block below through the fixed block. When the worker rotates the turntable above the fixed block, the turntable drives the threaded rod to rotate. The threaded rod controls the lifting and lowering of the guide rod below. The guide rod slides inside the fixed block. The guide rod can adjust the distance between the clamping block and the movable plate. When the guide rod slides, the limiting block slides inside the fixed block, improving the stability of the guide rod sliding inside the fixed block. The stepped groove is located above the turntable. The stepped groove is composed of multiple square grooves of different depths in a ring. The multiple square grooves are arranged in a way that blocks the bottom of the ejector pin into the interior of the stepped groove, which can limit the rotation of the turntable and improve the stability of the threaded rod rotation.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please refer to the following: Figures 1 to 4 A clamping mechanism for processing a front passenger seat bracket for automobiles includes: a base 1, a cylinder 5, and a bracket body 9. Multiple support columns 2 are fixedly connected at equal intervals above the base 1. Guide columns 21 are fixedly connected to the upper ends of the multiple support columns 2. Support plates 3 are fixedly connected to the upper ends of the multiple guide columns 21. Movable plates 4 are movably arranged on the surfaces of the multiple support columns 2. The cylinder 5 is fixedly arranged below the support plate 3. A pressure rod 51 is driven and connected to the lower output end of the cylinder 5. A clamping block 7 is fixedly inserted into the surface of the pressure rod 51. Two limiting components 6 are fixedly connected inside the movable plate 4. The two limiting components 6 are located on both sides of the pressure rod 51. The bracket body 9 is movably arranged above the base 1 and below the clamping block 7. A base 8 is fixedly connected above the base 1 and is located around the bracket body 9.

[0025] In this way, when the worker needs to punch the bracket body 9 during the implementation process, the worker will place the bracket body 9 on the base 1. The shape of the bracket body 9 will fit the inner wall of the base 8, reducing the movement of the bracket body 9 and improving the stability during the punching process. The support plate 3 is fixed above the base 1 by the clamping block 7. The cylinder 5 is fixed below the support plate 3. When the cylinder 5 is started, the cylinder 5 will drive the pressure rod 51 to extend downward. The middle of the pressure rod 51 has an outward protruding boss. The movable plate 4 is located above the boss, and the lower part of the movable plate 4 fits against the boss.

[0026] The movable plate 4 slides downward along the surface of the support column 2. The movable plate 4 drives the two internal limiting components 6 to descend. The limiting components 6 support the lower clamping block 7. The clamping block 7 presses the lower bracket body 9 to improve the fit between the bracket body 9 and the lower base 1, thereby improving the stability of the bracket body 9 during the punching process. The pressure rod 51 presses downward. The lower end of the pressure rod 51 passes through the clamping block 7 and is fixed with a punch. The punch punches the bracket body 9, increasing the efficiency and stability of the bracket body 9 in processing and clamping.

[0027] The base 1 has a receiving groove 11 and a guiding groove 12 inside. The guiding groove 12 and the receiving groove 11 are connected on one side. One end of the guiding groove 12 extends downward at an angle. The bracket body 9 is located above the receiving groove 11. The receiving groove 11 and the guiding groove 12 are mainly used to collect debris. When the bracket body 9 is punched, the debris will enter the guiding groove 12 through the receiving groove 11 below the bracket body 9, and then slide out through the inclined surface inside the guiding groove 12, which facilitates the worker to clean and collect the debris later.

[0028] Preferably, a plurality of limiting posts 81 are fixedly connected to the upper part of the base 8. One end of the plurality of limiting posts 81 passes through the clamping block 7, and the plurality of limiting posts 81 are respectively located on both sides of the two limiting components 6. When the limiting posts 81 extend upward, the limiting posts 81 will limit the clamping block 7, which can make the clamping block 7 more stable during the lifting process, reduce the friction of the clamping block 7, and greatly increase the stability of the clamping block 7.

[0029] Specifically, the limiting component 6 includes a fixed block 61 fixedly connected to the movable plate 4. A guide rod 62 is slidably inserted inside the fixed block 61. The lower end of the guide rod 62 is fixedly connected to the clamping block 7. A threaded rod 64 is threadedly connected to the upper end of the guide rod 62. A turntable 65 is fixedly connected to the upper end of the threaded rod 64. The turntable 65 rotates above the fixed block 61. The limiting component 6 fixes the clamping block 7 below through the fixed block 61. When the worker rotates the turntable 65 above the fixed block 61, the turntable 65 will drive the threaded rod 64 to rotate. The threaded rod 64 controls the lower guide rod 62 to rise and fall. The guide rod 62 will slide inside the fixed block 61. The guide rod 62 can adjust the distance between the clamping block 7 and the movable plate 4.

[0030] More specifically, a limiting block 63 is fixedly sleeved on the surface of the guide rod 62. The periphery of the limiting block 63 slides and fits in contact with the inside of the fixed block 61. The diameter of the limiting block 63 is larger than that of the guide rod 62. When the guide rod 62 slides, the limiting block 63 will slide inside the fixed block 61, thereby improving the stability of the guide rod 62 sliding inside the fixed block 61.

[0031] Furthermore, during implementation, a bracket 66 is fixedly connected above the fixing block 61, and a pin 67 is threadedly connected inside the bracket 66. A stepped groove 68 is annularly opened above the turntable 65, and the lower end of the pin 67 extends into the interior of the stepped groove 68. The stepped groove 68 is located above the turntable 65 and is composed of multiple square grooves of varying depths in a ring. The multiple square grooves are arranged in a way that separates the deep and shallow sections, allowing the lower part of the pin 67 to be engaged inside the stepped groove 68, which can limit the rotation of the turntable 65 and improve the stability of the rotation of the threaded rod 64.

[0032] The working principle of the clamping mechanism for processing the front passenger seat bracket of an automobile provided by this utility model is as follows:

[0033] When using the bracket body 9, the worker places it on top of the base 1. The shape of the bracket body 9 fits snugly against the inner wall of the base 8, reducing movement and improving stability during punching. The support plate 3 is fixed to the top of the base 1 by the clamping block 7. The cylinder 5 is fixed to the bottom of the support plate 3. When the cylinder 5 is activated, it drives the pressure rod 51 to extend downward. The pressure rod 51 has an outwardly protruding boss in the middle. The movable plate 4 is located above the boss, and the bottom of the movable plate 4 is flush with the boss. When the support column 2 is in place, the movable plate 4 slides downward along the surface of the support column 2. The movable plate 4 drives the two internal limiting components 6 to descend. The limiting components 6 support the lower clamping block 7 and press the lower bracket body 9 through the clamping block 7 to improve the fit between the bracket body 9 and the lower base 1, thereby improving the stability of the bracket body 9 during the punching process. The pressure rod 51 presses downward, and the lower end of the pressure rod 51 passes through the clamping block 7 and is fixed with a punch. The punch punches the bracket body 9, increasing the efficiency and stability of the bracket body 9 in the processing and clamping.

[0034] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
