Detailed implementation mode

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] Next, the present invention will be further described in conjunction with the accompanying drawings of the specification.

[0022] The present invention provides the following technical solutions:

[0023] As shown in the attached Figures 1-4 As shown, the present invention discloses a semi-automatic retaining ring pressing structure, including a bottom plate 1 and a vertical plate 26. A cylinder 2 and a mounting plate 3 are arranged on the bottom plate 1. The cylinder 2 and the mounting plate 3 are fixedly connected. A pressing plate 4 is arranged at one end of the cylinder 2 away from the mounting plate 3. A fixing member 5 is arranged on the bottom plate 1. A connecting component 6 is arranged on the fixing member 5. The pressing plate 4 horizontally presses towards one end of the fixing member 5. The pressing plate 4 presses the connecting component 6. In this design, the technical solution of this design fixedly connects the cylinder 2 and the mounting plate 3, and then uses the cylinder 2 to push the pressing plate 3 downward. After contacting the valve body 14, it drives the valve body 14 and the valve body limit sleeve to move downward. After continuing to press down, the valve body 14 contacts the spring seat 7 and drives it to move downward together (due to the presence of the spring 8, the spring seat 7 has not been pressed in place at this time). When the valve body 14 keeps moving downward until it contacts the retaining ring positioning sleeve 12 (the retaining ring positioning sleeve 12 is connected to the valve body 14), it drives the retaining ring positioning sleeve 12 to continue moving downward. Since the fixed shaft 28 does not move, the retaining ring 11 will be ejected, and the gland 10, valve 9, spring 8, and spring seat 7 will be pressed into the valve body 14. When the retaining ring 11 enters the valve body 14, the retaining ring 11 rebounds to prevent the components from coming out, effectively solving the problem of difficult pressing of the retaining ring 11 caused by the force of the spring 8. And with this pneumatic pressing, all the components are placed in place at one time and then pressed at one time, reducing steps and improving efficiency.

[0024] Furthermore, a snap ring positioning sleeve 12 and a valve body limiting sleeve 13 are arranged on the fixing part 5. A snap ring 11 is arranged on the snap ring positioning sleeve 12. The connecting component 6 includes a gland 10, a valve 9, a spring 8 and a spring seat 7 which are sequentially arranged on the snap ring 11. A valve body 14 is arranged in the valve body limiting sleeve 13. The cylinder 2 is arranged at one end of the valve body 14 away from the snap ring 11. One end of the cylinder 2 pushes the pressing plate 4 to drive the valve body 14 to move downward. The snap ring positioning sleeve 12 has a positioning protrusion 9. One end of the spring 8 extends into the positioning protrusion 9 to be connected with the snap ring positioning sleeve 12. The spring 8 is connected with the snap ring positioning sleeve 12. In this design, first, the snap ring 11 is installed in the snap ring positioning sleeve 12 with a snap ring pliers. Then, the gland 10, the valve 9, the spring 8, the spring seat 7 and the valve body 14 are placed in sequence. The cylinder 2 intakes air and pushes the pressing plate 4 to move downward. After contacting the valve body 14, it drives the valve body 14 and the valve body limiting sleeve 13 to move downward. After continuous pressing down, the valve body 14 contacts the spring seat 7 and drives it to move downward together. When the valve body 14 moves downward all the way to contact the snap ring positioning sleeve 12 (the small boss of the snap ring positioning sleeve 12 enters the valve body 14), it drives the snap ring positioning sleeve 12 to continue moving downward, and will push out the snap ring 11, and press the gland 10, the valve 9, the spring 8 and the spring seat 7 into the valve body 14. When the snap ring 11 enters the groove of the snap ring 11 in the valve body 14, the snap ring 11 rebounds to prevent the components from coming out.

[0025] Furthermore, an angle-shaped pull plate 15 and a guide rail 16 are arranged on the bottom plate 1. An angle-shaped pull handle 17 is arranged on the angle-shaped pull plate 15. A bolt connection groove 18 is opened on the angle-shaped pull plate 15. A bolt (not shown in the figure) is arranged in the bolt connection groove 18. The bolt passes through the angle-shaped pull handle 17 and extends into the bolt connection groove 18 to be connected with the angle-shaped pull plate 15. The angle-shaped pull handle 17 and the angle-shaped pull plate 15 are fixedly connected. A sliding connection groove 20 is arranged on the guide rail 16. The guide rail 16 is provided with a sliding protrusion end 21 corresponding to the sliding connection groove 20. The sliding protrusion end 21 extends into the sliding connection groove 20 to be connected with the guide rail 16. In this design, the arrangement of the angle-shaped pull plate 15 facilitates pulling out the fixing part 5 in the later stage for the retraction and deployment after extrusion. The design of the guide rail 16 improves the pulling speed of the angle-shaped pull handle 17.

[0026] Furthermore, the cylinder 2 has a cylinder adapter 25. A pressing plate connection hole 22 is opened on the pressing plate 4. The cylinder adapter 25 is provided with an adapter connection groove (not shown in the figure) corresponding to the size of the pressing plate connection hole 22. A cylindrical pin 24 is arranged in the adapter connection groove. The cylindrical pin 24 passes through the pressing plate connection hole 22 and extends into the adapter connection groove to be connected with the cylinder adapter 25. In this design, the cylinder 2 connector and the pressing plate 4 are connected through the cylindrical pin 24, which avoids the danger of the pressing plate 4 falling due to unstable connection during the later press-fitting process, and also improves the stability of the pressing plate 4 falling.

[0027] Furthermore, reinforcing ribs 27 are provided at both ends of the vertical plate 26. The reinforcing ribs 27 are respectively connected to the vertical plate 26 and the bottom plate 1. In this design, the design of the reinforcing ribs 27 strengthens the fixation between the bottom plate 1 and the vertical plate, avoids the dropping of product components caused by long-term work, and improves the service life of the product.
