[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Please refer to Figures 1 to 5 To achieve the above purpose, the utility model provides the following technical solutions:

[0023] An O-ring transport clamping device comprises a fixed bracket 1, wherein the lower end of the fixed bracket 1 is fixedly connected to a workbench (not shown) by bolts, welding or the like to ensure the stability of the entire clamping device during operation; a crossbeam is installed at the upper end of the fixed bracket 1, wherein a six-axis robot 2 is fixedly installed below the crossbeam, and the six-axis robot 2 can realize complex spatial movements due to the flexibility of its six joints; the end of the movable arm of the six-axis robot 2 is fixedly connected to the crossbeam through an end cover 3 to ensure the stability and accuracy of the movable arm during movement, wherein a fixed plate 4 is provided at the front end of the movable arm of the six-axis robot 2; one side of the fixed plate 4 is fixedly connected to the movable arm, wherein a clamping claw assembly 5 is installed on the other side of the fixed plate 4; the clamping claw assembly 5 comprises a base 501 and an internally supported clamping claw cylinder 502, wherein the base 5 One side of 01 is vertically connected to the fixed plate 4, thereby ensuring that the clamping action of the clamping jaw assembly 5 can be accurately performed; the cylinder end of the internal support clamping jaw cylinder 502 is fixedly connected to the base 501, and the internal support clamping jaw cylinder 502 adopts a six-finger clamping jaw cylinder, wherein the design of the six-finger clamping jaw cylinder makes the clamping end of the internal support clamping jaw cylinder 502 radially open six movable grooves 503 along its circumference, and a piston head 504 is installed in each movable groove 503; when the internal support clamping jaw cylinder 502 is working, the six piston heads 504 are controlled to move inward or outward at the same time, so as to realize the stable clamping or release of the O-ring 6; the device realizes the stable clamping and transportation of the O-ring 6 through the coordinated work of the fixed bracket 1, the six-axis robot 2 and the clamping jaw assembly 5, thereby improving the production efficiency and operation accuracy.

[0024] Please refer to Figure 3 , Figure 4 As an embodiment of the utility model, a push block 505 is provided at the upper end of the piston head 504, wherein six push blocks 505 are provided, and the six push blocks 505 are radially distributed with the axis of the inner support type clamping cylinder 502 as the center.

[0025] In the above-described scheme, the six push blocks 505 are evenly distributed in a radial shape with the axis of the internal support clamp cylinder 502 as the center. When the internal support clamp cylinder 502 is working, the push blocks 505 will move according to the movement of the piston head 504. Such a layout ensures that the push blocks 505 can be evenly stressed when the O-ring 6 is internally supported and fixed, thereby improving the stability and reliability of the internal support of the O-ring 6.

[0026] When it is necessary to clamp the O-ring 6, the internal support type clamping cylinder 502 starts working and drives the piston head 504 to move outward, so that the piston head 504 drives the push block 505 to move outward synchronously. Since the push blocks 505 are distributed radially, the six push blocks 505 will expand outward at the same time, thereby expanding and fixing the O-ring 6. Once the O-ring 6 is fixed by the internal support, the six-axis robot 2 can drive the clamping assembly 5 and the O-ring 6 to move to the pressing position together through the movable arm according to the preset path and action; after reaching the pressing position, the internal support type clamping cylinder 502 will work again, driving the piston head 504 to move inward, so that the piston head 504 drives the push block 505 to retract synchronously, thereby releasing the internal support for the O-ring 6. At this time, the O-ring 6 can be safely placed in the assembly position of the pressing assembly, completing the entire transportation process.

[0027] See also Figure 4 As an embodiment of the utility model, two positioning pins 7 are fixedly installed on the upper end of the piston head 504, and a positioning hole 8 matched with the positioning pins 7 is opened on the push block 505.

[0028] In the above-described scheme, two locating pins 7 are installed on the upper end of the piston head 504. The two locating pins 7 play the role of ensuring that the push block 505 is accurately and stably installed on the piston head 504. The push block 505 is provided with locating holes 8 that are compatible with the locating pins 7. The shapes, sizes and positions of these locating holes 8 are designed according to the locating pins 7 to ensure that the two can match accurately; the main function of the locating pins 7 and the locating holes 8 is to ensure that the position of the push block 505 on the piston head 504 is accurate and stable; moreover, the cooperation of the locating pins 7 and the locating holes 8 can prevent the push block 505 from deviating or shaking during the movement. This design not only improves the accuracy and reliability of clamping the O-ring 6, but also enhances the stability and safety of the entire clamping device.

[0029] Please refer to Figure 3 , Figure 4 As an embodiment of the utility model, a push block 505 is fixedly connected to an inner support rod 506 at one end close to the axis of the inner support type clamping cylinder 502, wherein the inner support rod 506 and the push block 505 are arranged perpendicular to each other; there are six inner support rods 506, wherein the six inner support rods 506 are spliced ​​into a cylindrical structure with the axis of the inner support type clamping cylinder 502 as the center.

[0030] In the above-mentioned scheme, the push block 505 is fixedly connected to the inner support rod 506 at one end close to the axis of the inner support type clamping claw cylinder 502. This connection method ensures that when the push block 505 moves, the inner support rod 506 can move synchronously, thereby realizing the opening and closing of the inner support rod 506; the inner support rod 506 and the push block 505 are arranged perpendicular to each other. This design not only ensures the uniform distribution of the clamping force, but also enables the inner support rod 506 to form a tight circular structure when opening and closing to adapt to the shape of the O-ring 6; the inner support rod 506 is provided with six, And corresponding to the six movable grooves 503 of the internal support type clamping cylinder 502, such a design ensures that the push block 505 in each movable groove 503 is connected to an internal support rod 506, thereby realizing the uniform contraction and expansion of the internal support rod 506; when the internal support type clamping cylinder 502 is working, the six internal support rods 506 will move inward or outward synchronously to form a cylindrical clamping space. The size of this cylindrical space can be precisely adjusted by controlling the moving distance of the piston head 504 of the internal support type clamping cylinder 502 to accommodate O-rings 6 of different sizes.

[0031] When it is necessary to clamp the O-ring 6, the internal support claw cylinder 502 drives the piston head 504 to move outward, wherein the movement of the piston head 504 drives the push block 505 to move outward synchronously, and then the push block 505 drives the internal support rod 506 to expand outward. Since the six internal support rods 506 are spliced ​​into a cylindrical structure with the axis of the internal support claw cylinder 502 as the center, the six internal support rods 506 will expand outward synchronously to form a cylindrical space, thereby expanding and fixing the O-ring 6 to ensure that the O-ring 6 will not fall off or shift during transportation; when the O-ring 6 is fixed by the internal support, the six internal support rods 506 will expand outward synchronously to form a cylindrical space. The axis robot 2 can move the clamping jaw assembly 5 and the O-ring 6 to the pressing position through the movable arm according to the preset path and action; after reaching the pressing position, the internal support clamping jaw cylinder 502 will work again, driving the piston head 504 to move inward, so that the piston head 504 drives the push block 505 to retract synchronously, and then drives the internal support rod 506 to retract inward. As the internal support rod 506 retracts, the internal support space gradually shrinks, and finally releases the internal support fixation of the O-ring 6. At this time, the O-ring 6 can be safely placed in the assembly position of the press-fitting assembly, completing the entire transportation process.

[0032] See also Figure 5 As an embodiment of the utility model, one end of the inner support rod 506 is fixedly connected to the push block 505, wherein a limiting groove 9 is provided on the outer wall of the other end of the inner support rod 506.

[0033] In the above-described scheme, one end of the inner support rod 506 is fixedly connected to the push block 505, so that the push block 505 can drive the inner support rod 506 to move synchronously when moving, thereby ensuring the stability and accuracy of the inner support rod 506 when clamping and releasing the O-ring 6; by providing a limiting groove 9 adapted to the O-ring 6 on the outer wall of the other end of the inner support rod 506, wherein the size and shape of the limiting groove 9 are customized according to the specific size and shape of the O-ring 6, when the inner support jaw cylinder 502 drives the piston head 504 to drive the push block 505 synchronously When moving outward, the push block 505 drives the inner support rod 506 to expand outward. As the inner support rod 506 expands outward, since the outer wall of the inner support rod 506 is provided with a limiting groove 9 compatible with the O-ring 6, when the inner support rod 506 expands to a certain extent, the inner ring of the O-ring 6 can be completely embedded and stably fixed in the limiting groove 9. This design ensures the stability and safety of the O-ring 6 during the clamping process, prevents the O-ring 6 from shifting or falling off during the transportation process, thereby achieving efficient and stable clamping and transportation of the O-ring 6.
