Description

Technical Field

[0001] This utility model relates to the technical field of valve core assembly equipment, and in particular to a clamping structure for facilitating valve core assembly of retaining rings. Background Technology

[0002] Currently, in faucet valve cores, a retaining ring is fitted onto the top of the valve core housing to limit the valve stem's movement and restrict its left and right rotation. Common retaining rings are mostly C-shaped elastic rings with two opposing folded edges at the opening. Before installation, the retaining ring's opening needs to be manually pressed closed. The pressed retaining ring is then fitted onto the top of the valve core housing, and the pressure is released, allowing the retaining ring to fit tightly against the inner wall of the valve core housing under elasticity. However, manually pressing the retaining ring opening results in low assembly efficiency for the valve core. Utility Model Content

[0016] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of protection of this utility model.

[0017] Please see Figure 1A clamping and conveying structure for assembling a retaining ring 10 onto the top of a valve core housing is disclosed. The structure includes a clamping ring unit 20 and a transfer plate 30. The retaining ring 10 forms an elastic ring body 11 with a C-shaped opening and two folded edges 12 arranged opposite to each other at the opening of the elastic ring body 11. The clamping ring unit 20 includes a base plate 21, a positioning seat 22, a wide air gripper 23, and two clamping arms 24. The positioning seat 22 and the wide air gripper 23 are mounted one in front of the other on the top surface of the base plate 21. The top of the positioning seat 22 is recessed and formed with a positioning groove 221 for the retaining ring 10 to be placed flat with its opening facing forward, and a guide groove 222 that runs straight through from one side to the other corresponding to the opening position of the retaining ring 10.

[0018] The wide-type pneumatic gripper 23 has two gripper arms 231 that can move forward and backward synchronously relative to the two sides of the positioning seat 22. Each gripper arm 231 is equipped with a corresponding clamping arm 24. The clamping arm 24 has a main arm section 201 that can pass through the guide groove 222 and the positioning groove 221, so that the retaining ring 10 in the open state can be placed flat in the positioning groove 221. The wide-type pneumatic gripper 23 drives the two clamping arms 24 to move closer to the positioning seat 22. Each main arm section 201 pushes against a folded edge 12 along the guide groove 222, applying pressure to the two folded edges 12 until the opening of the elastic ring 11 is closed.

[0019] The transfer plate 30 has a positioning port 31 through the top and bottom surfaces to position the retaining ring 10 in the open and closed state, and a positioning groove 32 is recessed on both sides of the bottom surface corresponding to the guide groove 222. After the wide-type pneumatic gripper 23 closes the opening of the retaining ring 10, the transfer plate 30 is fitted onto the retaining ring 10 through the positioning port 31 to maintain the open and closed state or the slightly open state of the retaining ring 10. Each positioning groove 32 corresponds to a main arm section 201. As the wide-type pneumatic gripper 23 drives the two clamping arms 24 away from the positioning seat 22, the transfer plate 30 removes the retaining ring 10 and after the retaining ring 10 is assembled onto the top of the valve core housing, the transfer plate 30 is removed.

[0020] Furthermore, in this embodiment, the substrate 21 has several fixing holes 211 between the positioning seat 22 and the wide air gripper 23 to fix the substrate 21 to the outside.

[0021] Furthermore, in this embodiment, the positioning groove 221 forms a ring receiving area 41 for receiving the elastic ring 11 and a folded edge receiving area 42 for receiving the two folded edges 12. The guide groove 222 is located between the ring receiving area 41 and the folded edge receiving area 42. The length and width of the ring receiving area 41 match the elastic ring 11 in the open state, and the width of the folded edge receiving area 42 matches the distance between the two folded edges 12 in the open state.

[0022] Furthermore, in this embodiment, the positioning opening 31 is formed with a first positioning segment 311 for accommodating the elastic ring 11 and a second positioning segment 312 for accommodating the two folded edges 12. The first positioning segment 311 has a concave arc transition edge 313 in the region of each adjacent second positioning segment 312 to facilitate accommodating the elastic ring 11. The width of the first positioning segment 311 is greater than the width of the elastic ring 11 in the open and closed state, and the distance between the top edge of the first positioning segment 311 and the concave arc transition edge 313 is greater than the length of the elastic ring 11 in the open and closed state. The width of the second positioning segment 312 is equal to the distance between the two folded edges 12 in the open and closed state or the slightly open state.

[0023] Furthermore, in this embodiment, the clamping arm 24 includes a connecting block 241 and a main arm body 242. The rear end of the connecting block 241 is connected to the inner side of the claw arm 231, and the front end of the connecting block 241 is located on one side of the positioning seat 22. The main arm body 242 is installed on the inner side of the front end of the connecting block 241. The main arm body 242 has a main arm segment 201 at one end facing the positioning seat 22 and a fixing seat 202 connected to the connecting block 241 at the other end away from the positioning seat 22.

[0024] Understandably, the method of using the clamping and conveying structure for assembling a valve core retaining ring according to this utility model includes the following steps: First, after the retaining ring 10 in its open state is placed flat into the positioning groove 221, the wide-type pneumatic gripper 23 is activated. The wide-type pneumatic gripper 23 drives the two clamping arms 24 to move closer to the positioning seat 22. Each main arm segment 201 pushes against a corresponding folded edge 12 along the guide groove 222, applying pressure to the two folded edges 12 until the opening of the elastic ring body 11 is closed. Second, the transfer plate 30 is fitted onto the retaining ring 10 with the positioning port 31, maintaining the retaining ring 10 in an open and closed state or a slightly open state. Third, as the wide-type pneumatic gripper 23 drives the two clamping arms 24 away from the positioning seat 22, the transfer plate 30 removes the retaining ring 10. After the retaining ring 10 is assembled onto the top of the valve core housing, the transfer plate 30 is removed. This completes the assembly of the retaining ring 10.

[0025] In summary, the clamping and conveying structure of this utility model for facilitating valve core assembly of the retaining ring, through the cooperation between the clamping ring unit 20 and the transfer plate 30, can efficiently press the retaining ring 10 from an open state to an open-closed state with the clamping ring unit 20, and assemble the open-closed retaining ring 10 onto the top of the valve core housing with the transfer plate 30, effectively improving the valve core assembly efficiency.

[0026] Any combination of different embodiments of this utility model, provided it does not violate the inventive concept of this utility model, shall be considered as the disclosure of this utility model; any simple modifications to the technical solution and any combination of different embodiments within the scope of the inventive concept of this utility model, without violating the inventive concept of this utility model, shall be within the protection scope of this utility model.
