Abstract
Description
Technical Field
[0001] This utility model relates to the field of sheet metal processing technology, and in particular to a sheet metal positioning and clamping device. Background Technology
[0002] A clamping device is a tooling device that applies clamping force mechanically or pneumatically to fix a workpiece in a preset position. It features secure fixing and convenient operation, and its core function is to ensure that the workpiece does not shift during processing, making it suitable for various precision machining scenarios. It is closely related to the positioning of sheet metal parts. Sheet metal processing requires precise positioning references, and positioning structures alone are prone to displacement due to external forces or vibrations. The clamping device is the key to ensuring that positioning accuracy does not fail.
[0003] In the prior art, some sheet metal positioning and clamping devices achieve precise fixation of sheet metal parts during processing through the synergistic effect of positioning reference and clamping force. The device first constrains the sheet metal parts at the preset processing reference position through structures such as positioning pins and stops, and clarifies their spatial coordinates to ensure accurate processing position; then, through pneumatic, hydraulic or manual drive mechanism, it drives clamping components such as pressure plate and chuck to apply a uniform and stable clamping force to the sheet metal parts.
[0004] In practical use, some clamping plates have fixed positions and angles, which cannot be adapted to sheet metal parts of different shapes and sizes. They can only process products of a single specification, resulting in extremely poor versatility. This increases the cost of purchasing special tooling, and the clamping plate spacing and clamping points cannot be adjusted. It is difficult to achieve accurate positioning for irregular or complex sheet metal parts, and the reference offset is prone to occur during processing, leading to dimensional deviations.
[0005] Therefore, it is necessary to provide a new sheet metal positioning and clamping device to solve the above-mentioned technical problems. Utility Model Content

[0007] The present invention provides a sheet metal part positioning and clamping device comprising: a mounting base, wherein mounting frames are fixedly connected to the front and rear sides of the mounting base, a clamping adjustment mechanism is slidably connected to the outside of the mounting frames, and connecting frames are fixedly connected to the four corners of the mounting base, wherein mounting mechanisms are slidably connected to the outside of the connecting frames. The clamping adjustment mechanism includes sliders, with connecting plates fixedly connected to the outer sides of the two sliders. A fixing block is fixedly connected to the outer bottom end of the connecting plate. A limiting plate is slidably connected inside the fixing block. Sliding rods are fixedly connected to both the front and rear sides of the bottom end of the limiting plate. A return spring is sleeved on the outside of the sliding rod.

[0011] Preferably, a pull plate is fixedly connected to the outside of the sliding lever, and the outside of the pull plate is in contact with the outside of the connecting frame.
[0012] Preferably, a workbench is slidably connected to the top of the mounting base, and the outer bottom end of the sliding lever is locked to the outside of the workbench.

[0015] Compared with related technologies, the sheet metal positioning and clamping device provided by this utility model has the following advantages: This invention uses a pull ring in the adjusting assembly to move the limiting plate, sliding rod, and through-hole block. Combined with the elasticity of the return spring, this allows the positioning rod to slide within the through-hole block, enabling flexible adjustment of the pressure plate position. The slider slides on the mounting bracket, moving the connecting plate and fixing block, allowing for overall adjustment of the clamping mechanism position. This structure solves the problem of fixed clamping plate position in traditional systems, adapts to sheet metal parts of different shapes and sizes, eliminates the need for specialized tooling, significantly reduces equipment investment costs, and improves the device's versatility.
[0016] This invention allows for flexible adjustment of the clamping plate spacing and clamping points through the sliding cooperation of the through-hole block and the positioning rod, enabling multi-point precise clamping of irregularly shaped sheet metal parts. The worktable is quickly positioned through the cooperation of the sliding latch and tension spring, and combined with the adjustable angle of the pressure plate, it can stably fix complex workpieces and avoid datum offset during processing.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.
[0020] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.
[0021] Please see Figures 1 to 4 A sheet metal part positioning and clamping device includes: a mounting base 1, which provides a stable mounting platform for components such as mounting brackets 2 and connecting brackets 15, and transmits the weight of the entire device and the force generated during operation to the base, ensuring that the device will not shake or shift during the positioning and clamping of sheet metal parts; mounting brackets 2 are fixedly connected to the front and rear sides of the mounting base 1, which provide mounting and sliding track support for the clamping adjustment mechanism, and enhance the overall structural strength of the device, so that the clamping adjustment mechanism can slide stably along it, realizing the adjustment of the clamping range for sheet metal parts of different sizes; the clamping adjustment mechanism is slidably connected to the outside of the mounting brackets 2; connecting brackets 15 are fixedly connected to the four corners of the outside of the mounting base 1, which provide mounting and sliding support for the mounting mechanism, so that the mounting mechanism can be adjusted in the vertical or horizontal direction to adapt to the positioning requirements of sheet metal parts of different thicknesses or shapes, and enhance the structural stability of the four corners of the device; the mounting mechanism is slidably connected to the outside of the connecting brackets 15. The clamping adjustment mechanism includes sliders 3, which drive components such as connecting plates 4 to slide along the mounting bracket 2, thereby achieving lateral adjustment of the clamping position. The sliding accuracy directly affects the positioning accuracy of the sheet metal parts. Connecting plates 4 are fixedly connected to the outer, adjacent sides of the two sliders 3. Connecting plates 4 connect the two sliders 3 into a single unit, ensuring synchronized movement during sliding and preventing the clamping mechanism from tilting due to the offset of a single slider 3. Simultaneously, it provides a mounting carrier for the fixing block 5, evenly transmitting the clamping force to the sliders 3. The outer bottom end of the connecting plate 4 is fixedly connected to… The fixing block 5 provides installation support for the limiting plate 6 and transmits the force of the connecting plate 4 to the limiting plate 6 through its own rigid structure, ensuring that the clamping force can effectively act on the sheet metal part. The fixing block 5 is internally slidably connected to the limiting plate 6. The bottom end of the limiting plate 6 is fixedly connected to the front and rear sides with sliding rods 7. The sliding rods 7 provide guidance for the sliding of the limiting plate 6, ensuring that it always moves in the vertical direction and avoids tilting. The sliding rods 7 are externally sleeved with a return spring 8, and the bottom end of the sliding rods 7 is fixedly connected to a through hole block 9. See Figures 2 to 3 The through-hole block 9 provides an installation platform for the adjustment assembly. Through the cooperation of the positioning rod 10 and the limiting block 11, the position of the pressure plate 12 is adjusted, thereby adjusting the distribution of the clamping force. An adjustment assembly, including the positioning rod 10, is slidably connected to the outside of the through-hole block 9. This adjustment assembly provides positioning and support for the limiting block 11. By adjusting its own position within the through-hole block 9, it moves the limiting block 11 and the pressure plate 12, achieving fine-tuning of the clamping position and enhancing the adaptability of the device. The positioning rod 10 is slidably connected to the outside of the through-hole block 9. At the through hole, multiple limiting blocks 11 are slidably connected inside the through hole block 9. The limiting blocks 11 adjust their own position by sliding, thereby driving the pressure plate 12 to change the contact point with the sheet metal part, while limiting the excessive movement of the pressure plate 12 to ensure the safety of the clamping action. The pressure plate 12 is fixedly connected to the outside of the limiting block 11. A power assembly is fixedly connected to the top of the limiting plate 6. The power assembly includes a worktable 13. The worktable 13 is fixedly connected to the top of the limiting plate 6. A pull ring 14 is fixedly connected to the outside of the worktable 13.
[0022] See Figures 3 to 4The installation mechanism includes a sliding lever 16, which achieves locking or unlocking actions through its own sliding. It is a key actuator for fixing the position of the worktable 13 in the installation mechanism, and can quickly connect and separate the worktable 13 from the connecting frame 15. The external sliding connection of the sliding lever 16 is connected to the inside of the connecting frame 15. The connecting frame 15 has a cavity 17 inside, and a limit plate 18 is slidably connected inside the cavity 17. The limit plate 18 limits the sliding range of the sliding lever 16 to prevent the sliding lever 16 from detaching from the cavity 17 due to excessive sliding. At the same time, it serves as the force carrier of the tension spring 19, transmitting the spring force to the sliding lever 16. The tension spring 19 is sleeved on the outside of the sliding lever 16. The tension spring 19 provides a restoring force for the sliding lever 16: when the sliding lever 16 is pulled upward by an external force, the spring is further stretched and stores elastic potential energy; when the external force is pulled upward by an external force, the spring is further stretched and stores elastic potential energy. After the force is released, the spring force pulls the sliding lever 16 downward to reset it, keeping it locked to the worktable 13. The sliding lever 16 is externally fixedly connected to a pull plate 20, which provides a force application point for the operator. By pulling the pull plate 20 upward, the sliding lever 16 is moved to slide, separating it from the worktable 13, making it easy to adjust the position of the worktable 13. The operation is convenient and labor-saving. The outside of the pull plate 20 is in contact with the outside of the connecting frame 15. The top of the mounting base 1 is slidably connected to the worktable 13. The bottom of the sliding lever 16 is locked to the outside of the worktable 13. The inside of the limiting plate 2 18 is fixedly connected to the outside of the sliding lever 16, and the outside of the sliding lever 16 is slidably connected to the inside of the cavity 17. One end of the reset spring 8 is fixedly connected to the bottom of the fixed block 5, and the other end of the reset spring 8 is fixedly connected to the top of the through hole block 9.
[0023] The working principle of the sheet metal part positioning and clamping device provided by this utility model is as follows: First, by pulling the pull plate 20, the pull plate 20 causes the sliding latch 16 to slide within the cavity 17 of the connecting frame 15. At the same time, the sliding latch 16 causes the limiting plate 18 to slide within the cavity 17, and the tension spring 19 is compressed. Next, the worktable 13 is placed on top of the mounting base 1 and adjusted to a suitable position. The pull plate 20 is then released. Under the reset action of the tension spring 19, the sliding latch 16 slides downward, and its bottom end locks into the worktable 13, completing the installation and positioning of the worktable 13.
[0024] By pulling the pull ring 14, the pull ring 14 moves on the fixed block 5 via the limiting plate 6. The limiting plate 6 drives the sliding rod 7 to move, and the sliding rod 7 drives the through-hole block 9 to move, thus stretching or compressing the return spring 8. At the same time, the positioning rod 10 of the adjusting component slides at the through hole of the through-hole block 9, and the limiting block 11 slides within the through-hole block 9, thereby driving the pressure plate 12 to move and adjusting the position of the pressure plate 12. Afterward, the slider 3 slides on the mounting bracket 2, and the slider 3 drives the connecting plate 4 to slide. The connecting plate 4 drives the fixed block 5 to slide, thereby adjusting the overall position of the clamping adjustment mechanism so that the pressure plate 12 is aligned with the clamping position of the sheet metal part.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
