[0021] The present invention is described in further detail below with reference to the accompanying drawings.
[0022] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are for illustrative purposes only, and those skilled in the art will readily appreciate other obvious variations. The basic principles of the present invention as defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.
[0023] As attached Figure 1-6The illustrated embodiment shows a floating flexible positioning mechanism comprising a mounting base 1 and a floating assembly 2. The floating assembly 2 includes positioning members 2.3 and a floating plate 2.1 for mounting a clamping jaw assembly 5. The floating plate 2.1 is provided with multiple floating members 2.2. The mounting base 1 flexibly engages with the floating plate 2.1 via the floating members 2.2. Multiple positioning members 2.3 located around the floating plate 2.1 are fixed to the mounting base 1 and serve to position the floating plate 2.1. The floating plate 2.1 is also provided with guide posts 2.13. Specifically, the guide posts 2.13 cooperate with the guide sleeve on the mold to achieve directional clamping. When the guide posts 2.13 and the guide sleeve deviate from each other, the guide posts 2.13 drive the floating plate 2.1, which in turn drives the floating assembly 2, to automatically position the guide sleeve with the mold. Specifically, because the floating plate 2.1 can be fine-tuned in multiple directions driven by the guide posts 2.13, the accuracy and tolerance of the debugging and pairing process are improved, wear is reduced, and the service life is increased. At the same time, the positioning member 2.3 provided in the present invention can realize the preliminary positioning of the floating plate 2.1, further ensuring the reliability and smoothness of the debugging and pairing.
[0024] Building on the above, a floating plate 2.1 is positioned beneath the mounting base 1. The floating element 2.2 comprises a connecting rod 2.21 and a thrust bearing 2.22. The mounting base 1 defines mounting holes 1.1 corresponding to the connecting rods 2.21. The connecting rods 2.21 flexibly extend through the floating plate 2.1, while the thrust bearings 2.22 are positioned over the corresponding connecting rods 2.21 and clamped to the upper and lower sides of the floating plate 2.1. The coordination between the connecting rods 2.21 and the thrust bearings 2.22 allows for floating adjustment of the floating plate 2.1, thereby improving the reliability and error tolerance of the mechanical gripper during alignment and extending its service life. After gripping is complete, i.e., after the guide post 2.13 is disengaged from the guide sleeve, the floating plate 2.1 automatically returns to its center position under the action of the floating element 2.2.
[0025] It is worth mentioning that positioning angles 2.11 are provided around the floating plate 2.1, and the positioning members 2.3 correspond one-to-one with the positioning angles 2.11. By cooperating with the multiple positioning angles 2.11 and the corresponding positioning members 2.3, the floating plate 2.1 can be initially positioned, and a rebound force is provided for the floating plate 2.1 after displacement to ensure accurate reset. Specifically, the positioning member 2.3 includes a fixed seat 2.31, which is fixed to the mounting seat 1. The fixed seat 2.31 is provided with a limiting rod 2.32 located on both sides of the positioning angle 2.11. The limiting rod 2.32 is provided with a ball 2.33, which presses the floating plate 2.1. The cooperation between the limiting rod 2.32 and the ball 2.33 achieves the initial positioning of the floating plate 2.1 while reducing wear and impact on the floating plate 2.1. A compression spring can be provided within the limiting rod 2.32 to ensure that the ball 2.33 is in close contact with the floating plate 2.1.
[0026] The lower side of the floating plate 2.1 of the present invention is provided with a connecting seat 2.12, to which a guide post 2.13 is fixed. The connecting seat 2.12 is fixed with two guide posts 2.13 arranged side by side, which can further improve the guiding performance and the stability after the pairing.
[0027] In order to improve the production clamping efficiency, the mounting base 1 is provided with multiple floating components 2 side by side, that is, multiple groups of clamping jaw components 5 can be provided to achieve high-efficiency clamping.
[0028] The clamping assembly 5 of the present invention is configured as follows: a mounting base 1 defines an assembly hole 1.2 corresponding to a floating plate 2.1; an adjustment actuator 3 is fixed to the floating plate 2.1; the adjustment actuator 3 extends upward through the assembly hole 1.2 and is located within the mounting base 1; the telescopic shaft of the adjustment actuator 3 is fixed to the adjustment plate 4; and the clamping assembly 5 is disposed on the adjustment plate 4. The clamping assembly 5 includes a lifting actuator 5.1 and a clamping actuator 5.5. The side of the adjustment plate 4 is provided with a plurality of support rods 5.2 that movably penetrate the floating plate 2.1 and extend into the mounting base 1.
