[0029] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.
[0030] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0031] The first embodiment of this utility model:
[0032] like Figure 1 As shown, the present invention provides a steel wire retaining ring pressing mechanism, which mainly includes a pressing cylinder 1, a pressing cylinder fixing plate 3, a pressing head mounting base plate 6, a pressing head 7, a product top cover 8, a steel wire retaining ring 9, an annular tooling 10, a molecular sieve tank 11, a sieve tank tooling 12, and a tooling base plate 13, etc.
[0033] The above structural components can be mainly divided into three parts: the press-in unit, the product unit, and the tooling unit.
[0034] I. The pressing unit mainly includes pressing cylinder 1, pressing cylinder fixing plate 3, pressing head mounting base plate 6, and pressing head 7.
[0035] The driving end of the bottom of the pressing cylinder 1, which is mounted on the pressing cylinder fixing plate 3, drives the pressing head mounting base plate 6 below to move vertically through the floating joint 5. During the movement of the pressing head mounting base plate 6, it can be guided by multiple guide shafts 2. The pressing head 7 is mounted on the bottom of the pressing head mounting base plate 6 through the connecting shaft 14. The pressing head 7 is the main working component of this utility model.
[0036] like Figure 2 As shown, four press-in feet 16 are evenly distributed along the circumference on the press head 7. The press-in feet 16 are rotatably mounted on the press head 7 near the center by a pin 17. After all four press-in feet 16 are inserted into the body of the press head 7, an O-ring 15 is fitted on its top to reset the four press-in feet 16, so that the press-in feet 16 are always in the open state when not in operation.
[0037] In addition, a clearance is designed around the main body of the pressure head 7 (i.e., a clearance groove is provided on the pressure head 7 to allow the protrusion on the top of the product cover 8 to be cleared), so that the air nozzle on the top of the product cover 8 can fall into the main body of the pressure head 7.
[0038] During operation, the lower surface of the pressure head 7 presses against the surface of the product top cover 8, ensuring that the surface of the product top cover 8 is evenly stressed. Except for the O-ring 15, which is a standard part, all other parts of this pressure head 7 are made of mold steel through heat treatment, achieving a hardness of HRC58-62, making it more wear-resistant.
[0039] II. The product unit mainly includes the product top cover 8, the wire retaining ring 9, and the molecular sieve tank 11. The tooling unit mainly includes the annular tooling 10, the sieve tank tooling 12, and the tooling base plate 13.
[0040] like Figure 1 As shown, the product top cover 8 is used to be installed on the molecular sieve tank 11, and the steel wire retaining ring 9 is used to be installed in the retaining ring groove 19 on the product top cover 8.
[0041] The bottom of the molecular sieve tank 11 is installed inside the sieve tank fixture 12, which is mounted on the working platform via the fixture base plate 13. An annular fixture 10 is installed on the top of the molecular sieve tank 11 to assist in the installation of the product top cover 8 and the wire retaining ring 9. This annular fixture 10 is made of mold steel through heat treatment, achieving a hardness of HRC58-62 for enhanced wear resistance.
[0042] like Figure 3As shown, an outer step 18 is provided on the product top cover 8 above the retaining ring groove 19. The outer diameter of the outer step 18 is smaller than the inner diameter of the wire retaining ring 9, which facilitates the pressing in of the wire retaining ring 9.
[0043] A chamfered groove 20 is provided on the top inner side of the annular tooling 10, and the inner diameter of the chamfered groove 20 gradually decreases from top to bottom, which facilitates the pressing foot 16 of the pressing head 7 to be pressed in. The bottom diameter matches the size of the molecular sieve tank 11 opening, so that the wire retaining ring can be pressed in.
[0044] A tooling protrusion 21 protruding inward is provided in the middle of the inner side of the annular tooling 10. The contact surface of the inner side of the tooling protrusion 21 is a smooth arc-shaped structure, which facilitates the product top cover 8 to be pressed better into the molecular sieve tank 11 below. The tooling protrusion 21 is engaged with the sieve tank engaging part 22 at the top of the molecular sieve tank 11. The inner diameter of the tooling protrusion 21 is larger than the outer diameter of the product top cover 8, so that the product top cover 8 can pass through freely.
[0045] Brief description of the working process of this utility model:
[0046] 1. Place the oxygen generator molecular sieve container 11 into the bottom sieve container fixture 12;
[0047] 2. Fit the annular tool 10 onto the top of the molecular sieve tank 11 (it can be removed after the wire retaining ring 9 is installed);
[0048] 3. Place the product top cover 8 into the molecular sieve tank 11;
[0049] 4. Place the wire retaining ring 9 on the top cover 8 of the product. The inner circle of the wire retaining ring 9 is larger than the first step of the top cover 8 (i.e., the outer step 18 of the top cover) to facilitate pressing it in.
[0050] 5. Press the manual start button. At this time, the upper pressing cylinder 1 drives the pressing head 7 to press down, pressing the wire retaining ring 9 and the product top cover 8 together into the molecular sieve tank 11. The wire retaining ring 9 falls into the retaining ring groove 19 to prevent the product top cover 8 from falling out of the molecular sieve tank 11.
