Technical Field
[0001] This utility model relates to the field of flexible clamps, and in particular to a flexible clamping device based on an automated housing display. Background Technology
[0002] Automated flexible housing clamping devices are used in automated production lines to clamp and fix various types of housings, especially for workpieces with irregular shapes, sizes, and weights, providing a flexible and efficient clamping solution. Through its flexible design, it can adapt to workpieces of different models or shapes, and through automated control, it achieves precise clamping.
[0003] Existing technologies, such as the invention with publication number CN113334064A, disclose an automated equipment for flexible tooling fixtures. This patent employs a workbench, and along the conveying direction of the material channel, the workbench is sequentially equipped with a housing feeding mechanism, a bearing assembly mechanism for installing bearings into the housing, an elastic wire and elastic clip feeding device for installing elastic steel wire and elastic clips into the housing, a detection and processing device for detecting whether the elastic steel wire is properly installed and cleaning the inner cavity of the housing, and a painting and drying device for painting the housing. Using the above scheme, this invention provides an automated equipment for flexible tooling fixtures that improves the pass rate and assembly effect.
[0004] The inventors discovered in daily use that existing flexible clamping devices are typically designed with a certain range of adaptability. However, for items with significant differences in model, shape, size, and weight, the system may not be able to adjust quickly and accurately. Especially when dealing with parts with different geometric features (such as different sizes, shapes, and surface materials), the clamp's adaptability is insufficient, leading to inefficient clamping and fixation. Flexible clamping devices often require adjustments to their shape or position within a certain range, but excessive adjustments may affect clamping accuracy. For multiple models of items, the automatic adjustment mechanism of the clamp often struggles to maintain precise clamping for each item, potentially affecting the precision requirements of the production line and leading to error accumulation. When different models of parts need to be replaced, the flexible clamp may require manual intervention or reconfiguration, resulting in reduced production efficiency. Especially in production environments requiring frequent model changes, the time and complexity of the clamp adjustment process can significantly impact production.

[0028] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.
[0029] Please see Figures 1 to 4This utility model provides a flexible clamping device based on an automated housing display, comprising: a mounting plate 1 and a connecting structure 9. A connecting plate 2 is mounted on the upper surface of the mounting plate 1. Four connecting rods 4 are fixed on the inner wall of the connecting plate 2. The four connecting rods 4 are divided into two groups of two. A connecting plate 3 is fixedly connected to the upper end of each group of connecting rods 4. An adjustment device 5 is provided between the connecting plate 3 and the connecting plate 2. The two ends of the adjustment device 5 are respectively connected to the connecting plate 3 and the connecting plate 2. An auxiliary component 7 is mounted on the upper surface of both ends of the mounting plate 1. An auxiliary plate 8 is provided at the lower end of the connecting rod 4. The auxiliary plate 8 is connected to the connecting rod 4 through the connecting structure 9. A suction cup component 6 is installed inside the auxiliary plate 8 at the end away from the connecting rod 4. A plurality of servo cylinders 10 are mounted on the lower surface of the mounting plate 1. An auxiliary rod 11 is mounted on both output ends of the servo cylinders 10. A connecting piece 12 is fixedly connected to the end of the auxiliary rod 11 away from the servo cylinder 10. A pressing block 13 is fixedly connected to the lower end of the connecting piece 12. When clamping an item is required, the mounting plate 1 and connecting plate 2 are moved to the appropriate position. Then, the servo cylinder 10 is positioned above the item to be clamped, and the servo cylinder 10 is started. The output end of the servo cylinder 10 drives the auxiliary rod 11 to move, which in turn drives the connecting piece 12 to move. The connecting piece 12 then retracts the squeezing block 13, which is placed inside the item to be clamped. The servo cylinder 10 is then started again to drive the squeezing block 13 to expand and clamp the item. The connecting rod 4 has a circular cross-section and is made of stainless steel. The stainless steel material increases the service life of the connecting rod 4 and prevents it from rusting during use. The lower end of the suction cup assembly 6 is arc-shaped and is made of rubber. The servo cylinder 10 is connected to the mounting plate 1 by several bolts. The mounting plate 1 has a rectangular cross-section, and the lower end of the connecting rod 4 has a connecting structure 9.
[0030] In the embodiments of this utility model, please refer to Figure 1 and Figure 4The connecting structure 9 includes a connecting rod 91, which is fixedly connected to the connecting rod 4. A connecting ring 92 is fixedly connected to the upper surface of the auxiliary plate 8. The connecting ring 92 is slidably connected to the connecting rod 91. Several sliding grooves 93 are provided on the inner wall of the connecting rod 91. A locking block 96 is slidably connected to the inner wall of the sliding groove 93. Several locking slots 94 are provided on the inner wall of the connecting ring 92. The locking slots 94 are engaged with the locking blocks 96. A spring 95 is provided inside the sliding groove 93. The two ends of the spring 95 are fixedly connected to the locking blocks 96 and the locking slots 94, respectively. When it is necessary to connect the suction cup assembly 6 to the connecting rod 4, the suction cup assembly 6 is pulled to move, which in turn moves the auxiliary plate 8. The auxiliary plate 8 then moves the connecting ring 92. The connecting ring 92 is then aligned with the connecting rod 91, and the connecting ring 92 is inserted into the connecting rod 91. The connecting ring 92 presses against the locking block 96, causing the locking block 96 to slide on the inner wall of the slide groove 93. The locking block 96 causes the spring 95 to retract. After moving to the appropriate position, the spring 95 stretches, causing the locking block 96 to engage with the locking slot 94 for fixation. A limiting rod 97 is fixedly connected inside the slide groove 93, and the limiting rod 97 is slidably connected to the locking block 96. The limiting rod 97 can limit the locking block 96, preventing it from shifting when sliding on the inner wall of the slide groove 93, thus improving the stability of the locking block 96's sliding. The limiting rod 97 has a circular cross-section, and the spring 95 is fitted onto the arc surface of the limiting rod 97. The limiting rod 97 can limit the spring 95, preventing the spring 95 from deforming during use and improving the service life of the spring 95;
[0031] The working principle of the flexible clamping device based on the automated housing provided by this utility model is as follows: When it is necessary to clamp an item, the mounting plate 1 and the connecting plate 2 are moved to a suitable position, and then the servo cylinder 10 is positioned above the item to be clamped. The servo cylinder 10 is then started to operate, and the output end of the servo cylinder 10 drives the auxiliary rod 11 to move. The auxiliary rod 11 drives the connecting piece 12 to move, and the connecting piece 12 drives the squeezing block 13 to retract. Then the squeezing block 13 is placed inside the clamped item, and the servo cylinder 10 is started to operate to drive the squeezing block 13 to expand and clamp and fix the item. The stainless steel material can increase the service life of the connecting rod 4 and prevent the connecting rod 4 from rusting during use.
[0032] When it is necessary to connect the suction cup assembly 6 to the connecting rod 4, pull the suction cup assembly 6 to move it. The suction cup assembly 6 drives the auxiliary plate 8 to move, and the auxiliary plate 8 drives the connecting ring 92 to move. Then, align the connecting ring 92 and the connecting rod 91, and insert the connecting ring 92 onto the connecting rod 91. The connecting ring 92 presses against the locking block 96, and the locking block 96 slides on the inner wall of the slide groove 93. The locking block 96 drives the spring 95 to retract. After moving to the appropriate position, the spring 95 stretches, causing the locking block 96 to lock into the locking groove 94 for fixation. The limiting rod 97 can limit the locking block 96 to prevent it from deviating when sliding on the inner wall of the slide groove 93, thus improving the stability of the sliding of the locking block 96. The limiting rod 97 can also limit the spring 95 to prevent it from deforming during use, thus improving the service life of the spring 95.
