Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0024] The O-shaped sealing ring is a circular rubber or plastic product, which is widely used in mechanical, automotive, aerospace and other industries, and is mainly used for preventing liquid or gas leakage. Such sealing ring is widely welcomed due to its simple structure, easy manufacturing and installation.

[0025] Based on the technical defects that the sealing ring is prone to deviation during installation in the prior art, please refer to Figures 1-6The utility model provides a kind of O type sealing ring assembly device, workpiece is placed on fixed sheet 6032, locating block 6034 is limited to workpiece four around, it can ensure the verticality of workpiece placement, guarantee the sealing groove on workpiece is in horizontal state, so subsequent sealing ring can be automatically fitted into sealing groove under the action of self shrinkage, realize the accurate installation of sealing ring, can avoid the situation that sealing ring installation appears deviation, to ensure the sealing property when subsequent use, the device includes base shell 1, motor 2 is installed in base shell 1, driving gear 3 is fixed on the output shaft of motor 2, one side of driving gear 3 is equipped with gear ring 4 and is engaged with it, gear ring 4 is fixedly connected at the bottom of rotating disc 5, rotating disc 5 is rotatably connected in base shell 1, rotating disc 5 is connected with multiple by moving to the outside to make the sealing ring be opened straining mechanism 6, straining mechanism 6 is slidably arranged on fixed disc 7, fixed disc 7 is fixedly connected on the surface of base shell 1, the center of base shell 1 is also fixedly provided with unseating mechanism 8;Sealing ring is placed on multiple straining mechanism 6 first, then work by motor 2 and drive rotating disc 5 to rotate under the meshing action of driving gear 3 and gear ring 4, rotating disc 5 drives multiple straining mechanism 6 to move to the outside, sealing ring can be opened at this time, after opening, workpiece is placed in the inside of straining mechanism 6, finally, the sealing ring on straining mechanism 6 is separated by unseating mechanism 8, so that it enters the sealing groove on workpiece and completes assembly work.

[0026] For the convenience of the assembly of sealing ring, please refer to Figure 4 And Figure 5 Straining mechanism 6 includes guide block 601, guide block 601 is slidably arranged in the guide hole 501 formed in rotating disc 5, guide block 601 is fixedly connected at the bottom of straining claw 602, and positioning assembly 603 is fixedly arranged on the inner wall of straining claw 602 close to the top; When rotating disc 5 rotates, guide block 601 moves and straining claw 602 moves synchronously under the action of guide hole 501, because guide hole 501 is inclined, so that multiple straining claws 602 can be driven synchronously.

[0027] To ensure that straining claw 602 can move smoothly, straining claw 602 is in the shape of "L", and outer sliding grooves are arranged on both sides of straining claw 602 and slidably arranged on fixed disc 7 through the outer sliding grooves; After straining claw 602 moves to the outside, sealing ring can be opened, so that its inner diameter becomes larger, and straining claw 602 can move smoothly on fixed disc 7 under the action of outer sliding groove.

[0028] To facilitate the entry of sealing ring into the sealing groove of workpiece, unseating inclined surface is arranged on the top of straining claw 602; After sealing ring is pushed to move upward, sealing ring enters the position of unseating inclined surface, and because unseating inclined surface has a guiding effect, sealing ring will gradually shrink and enter the sealing groove of workpiece.

[0029] To realize the positioning of the workpiece, please refer to Figure 5 The positioning assembly 603 includes a fixed sheet 6032 mounted on the inner wall of the spreading claw 602 by a bolt 6031, and a positioning block 6034 with a right trapezoidal cross section is mounted on the fixed sheet 6032 by a bolt 6033. Since one positioning assembly 603 is arranged on the inner side of each spreading claw 602, the workpiece placed on the fixed sheet 6032 can be limited in the four directions under the action of the positioning block 6034, so as to ensure the center positioning, and the height of the positioning sheet also represents the position of the sealing groove on the workpiece. The height of the positioning sheet can be changed to align the top of the spreading claw with the sealing groove, so that the sealing ring automatically shrinks to the sealing groove after being separated from the spreading claw 602, and precise positioning of the sealing ring assembly is realized.

[0030] To facilitate the separation of the sealing ring from the spreading claw 602, please refer to Figure 5 The ring separation mechanism 8 includes an electric push rod 801 mounted at the center of the base housing 1, and a lifting disc 802 is fixedly arranged at the top of the electric push rod 801. A plurality of guide grooves are formed in the lifting disc 802, and a ring separation block 803 is slidably arranged in the guide grooves. The ring separation block 803 is in the shape of “L”, and one end of the ring separation block 803 is slidably attached to the inner side of the spreading claw 602. After the sealing ring is spread, the ring separation block 803 will move outward with the spreading claw 602, and then the electric push rod 801 operates to move the lifting disc 802 and the ring separation block 803 upward. The ring separation block 803 pushes the sealing ring upward away from the spreading claw 602, so that the sealing ring can be directly embedded into the sealing groove of the workpiece after self-shrinking, and automatic installation of the sealing ring is realized.

[0031] To ensure that the ring separation block 803 moves with the spreading claw 602, a sliding block 804 is fixedly arranged on the outer wall of the ring separation block 803, and the sliding block 804 is slidably arranged in an inner sliding groove 6021 formed in the inner wall of the spreading claw 602. Under the action of the sliding block 804 and the inner sliding groove 6021, the ring separation block 803 moves with the spreading claw 602, and the ring separation block 803 can also move up and down in the spreading claw 602, which facilitates the ring separation movement.

[0032] It should be noted that the terms “include”, “contain” or any other variant thereof are intended to cover non-exclusive inclusion, so that the process, method, article or equipment including a series of elements not only includes those elements, but also includes other elements not explicitly listed or inherent to such process, method, article or equipment.
