[0061] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

On the contrary, the use of the terms "example," "exemplary," and the like is intended to present concepts in a concrete manner.

[0063] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0064] like Figure 1As shown, at least one disclosed embodiment provides a punching device for ASU, comprising: a supporting mechanism and a detecting mechanism; the detecting mechanism is arranged in the supporting mechanism, the supporting mechanism is suitable for supporting the valve seat 4, the detecting mechanism contacts the bottom surface of the valve seat 4, and the detecting mechanism is suitable for detecting whether the thickness of the bottom surface of the valve seat 4 is uniform; wherein the detecting mechanism comprises: a lifting ring 1; the lifting ring 1 is slidably connected to the supporting mechanism, the positioning posts 13 on the top surface of the lifting ring 1 are inserted into the bottom surface of the valve seat 4, and the positioning posts 13 are at least two; After the mechanism supports the valve seat 4, the supporting mechanism and the valve seat 4 form an inner chamber 25 and an outer chamber 26, and the lifting ring 1 is slidably set in the outer chamber 26. At this time, the gas in the inner chamber 25 is extracted outward. If the thickness of the bottom surface of the valve seat 4 is uneven, the inner chamber 25 is connected to the outer chamber 26. As the gas in the inner chamber 25 is extracted, the gas in the outer chamber 26 is also extracted. The negative pressure in the outer chamber 26 makes the lifting ring 1 move upward and lift the valve seat 4 through the positioning column 13; the detection of the bottom surface thickness of the valve seat 4 is realized to ensure the quality of the final product.

[0065] The bottom surface of the valve seat 4 is provided with a protruding portion, and the bottom surface of the portion needs to be parallel to the plane where the bottom surface of the valve seat 4 without the protruding portion is located, that is, the thickness of the protruding portion needs to be uniform, so as to ensure the accuracy of the valve seat 4, and then ensure the accuracy and quality of the ASU formed by the subsequent assembly of the valve seat 4; the protruding portion can be a circular ring, and the bottom surface of the circular ring needs to be parallel to the plane where the valve seat 4 without the circular ring portion is provided, that is, the axial thickness of the circular ring needs to be uniform, and the outer diameter of the circular ring is smaller than the inner diameter of the lifting ring 1, and the inner wall of the lifting ring 1 will not contact the outer wall of the circular ring when the lifting ring 1 rises. When the thickness of the ring is uniform, the bottom surface of the ring will be in complete contact with the top surface of the supporting sleeve 23, so that the inner chamber 25 and the outer chamber 26 are blocked, and the inner chamber 25 and the outer chamber 26 cannot be connected. If the thickness of the ring is uneven, the bottom surface of the ring will not be in complete contact with the top surface of the supporting sleeve 23, and a gap will appear between the bottom surface of the ring and the top surface of the supporting sleeve 23, resulting in the inner chamber 25 and the outer chamber 26 being connected due to the gap. This detection mechanism is used to detect unqualified valve seat 4 in which a gap appears between the ring and the top surface of the supporting sleeve 23 due to uneven thickness of the ring.

[0066] like Figure 3 and Figure 4As shown, in an optional embodiment, the support mechanism includes: a support block 2; a support groove 21 is provided on the top surface of the support block 2; a first through hole 22 is provided on the inner bottom surface of the support groove 21, and the first through hole 22 extends to the bottom surface of the support block 2; a support sleeve 23 is passed through the first through hole 22, and the top surface of the support sleeve 23 is lower than the inner bottom surface of the support groove 21; the lifting ring 1 is sleeved on the support sleeve 23, the outer wall of the lifting ring 1 contacts the inner wall of the first through hole 22, the lifting ring 1 and the first through hole 22 are sealed, and the lifting ring 1 and the support sleeve 23 are sealed to prevent gas from flowing out of the support block 2 from between the lifting ring 1 and the first through hole 22 or between the lifting ring 1 and the support sleeve 23; the inner bottom surface of the support groove 21 can contact the plane of the valve seat 4 without a protruding part, and the top surface of the support sleeve 23 can The bottom surface of the protruding part of the bottom surface of the valve seat 4 is in contact with the support block 2, and the support sleeve 23 is lower than the bottom surface of the support block 2. When the lifting ring 1 is lowered to the lowest position, the bottom surface of the lifting ring 1 is lower than the bottom surface of the support sleeve 23. The support sleeve 23 can also be set on the base, and a groove can be opened on the base so that the lifting ring 1 can be lowered to the lowest position. The bottom surface of the lifting ring 1 contacts the external atmosphere, so that the lifting ring 1 can rise when a negative pressure is formed in the outer chamber 26; the size of the support groove 21 can be larger than the size of the valve seat 4. When the valve seat 4 is placed, the top end of the positioning column 13 protrudes from the inner bottom surface of the support groove 21, so that the top end of the positioning column 13 can enter the groove on the bottom surface of the valve seat 4, which plays a role of pre-positioning. When the valve seat 4 is placed manually, it may not be aligned. Therefore, the positioning column 13 plays a role of pre-positioning, so that the protruding part of the bottom surface of the valve seat 4 can be aligned with the support sleeve 23.

[0067] In an optional embodiment, the valve seat 4 is suitable for being placed in the support groove 21, and at this time, the bottom surface of the valve seat 4 contacts the top surface of the support sleeve 23; the bottom surface of the support sleeve 23 is sealed, and the bottom surface of the support sleeve 23 is suitable for connecting to an external air source through an air pipe; an inner chamber 25 is formed between the support sleeve 23 and the bottom surface of the valve seat 4; the space between the outer wall of the support sleeve 23 and the inner wall of the first through hole 22, and the bottom surface of the valve seat 4 forms an outer chamber 26; the protruding portion of the bottom surface of the valve seat 4 blocks the open top surface of the support sleeve 23 to form an inner chamber 25 in the support sleeve 23, and the inner chamber 25 is connected to the bottom surface of the support sleeve 23. The air pipe can pump air to the outside. If the thickness of the protruding part of the bottom surface of the valve seat 4 is uniform and meets the requirements, the inner chamber 25 is in a sealed state, and the inner chamber 25 is not connected with the outer chamber 26. During the process of pumping air outward from the inner chamber 25, the gas in the outer chamber 26 cannot be pumped out. At this time, the lifting ring 1 remains stationary; if the thickness of the protruding part is uneven, the protruding part cannot completely cover the open top surface of the supporting sleeve 23, resulting in the inner chamber 25 and the outer chamber 26 being connected, the gas in the outer chamber 26 is also pumped out, and the outer chamber 26 forms a negative pressure. The lifting ring 1 moves upward to lift the valve seat 4. At this time, it can be judged that the thickness of the protruding part of the bottom surface of the valve seat 4 is unqualified and the valve seat 4 is unqualified.

[0068] In an optional embodiment, a plurality of strip grooves 24 are vertically opened on the inner wall of the first through hole 22; a slider 12 is provided on the outer wall of the lifting ring 1, and the slider 12 corresponds to and fits with the strip groove 24; the slider 12 is located in the corresponding strip groove 24, and the outer wall of the slider 12 contacts the inner wall of the strip groove 24; the lifting ring 1 can be lifted and lowered stably through the cooperation of the strip groove 24 and the slider 12.

[0069] In an optional embodiment, the detection mechanism includes: a pair of rotating components; the rotating components are arranged in the support block 2, and the rotating components extend from the top surface of the support block 2; the rotating components are in contact with the lifting ring 1.

[0070] In an optional embodiment, the rotating assembly includes: a rotating shaft 14 and a rotating block 16; the rotating block 16 is rotatably arranged in the support block 2; one end of the rotating shaft 14 is connected to the support block 2, and the other end of the rotating shaft 14 extends out of the top surface of the support block 2; the rotating shaft 14 is rotatably connected to the support block 2; the position where the rotating shaft 14 contacts the support block 2 is in a sealed state; the rotating shaft 14 extending out of the support block 2 can facilitate manual rotation of the rotating shaft 14 to adjust the position of the lifting ring 1.

[0071] like Figure 5 and Figure 6As shown, in an optional embodiment, a spiral groove 17 is provided on the outer wall of the rotating block 16; a column 11 corresponding to the rotating block 16 is provided on the outer wall of the lifting ring 1, and the column 11 is arranged horizontally; one end of the column 11 is connected to the outer wall of the lifting ring 1, and the other end of the column 11 is located in the spiral groove 17; when the rotating block 16 rotates, the lifting ring 1 is lifted and lowered by the cooperation of the spiral groove 17 and the column 11.

[0072] like Figure 2 As shown, in an optional embodiment, a disc 15 is provided on the top surface of the rotating shaft 14, and a plane is provided on the side wall of the disc 15; when the plane is close to the support groove 21, the disc 15 is completely located above the portion of the top surface of the support block 2 where the support groove 21 is not provided; an arc-shaped groove 41 corresponding to the disc 15 is provided on the outer wall of the valve seat 4; a groove adapted to the positioning column 13 is provided on the bottom surface of the valve seat 4; when the valve seat 4 is not placed in the support groove 21, the plane is close to the support groove 21, and the disc 15 is completely located above the portion of the top surface of the support block 2 where the support groove 21 is not provided, thereby avoiding obstruction of the support groove 21 by the disc 15 and ensuring that the valve seat 4 can be smoothly placed in the support groove 21.

[0073] In the initial state, the valve seat 4 has not been placed in the support groove 21. At this time, the lifting ring 1 is in an upper position, the top surface of the lifting ring 1 is higher than the top surface of the support sleeve 23, the plane of the disc 15 is close to the support groove 21, and the disc 15 is completely located above the portion of the top surface of the support block 2 where the support groove 21 is not provided. The top end of the positioning column 13 is higher than the inner bottom surface of the support groove 21. At this time, the valve seat 4 is placed in the support groove 21, and the top end of the positioning column 13 is inserted into the groove on the bottom surface of the valve seat 4 to pre-position the valve seat 4. The protruding part of the bottom surface of the valve group contacts the top surface of the support sleeve 23. The disc 15 is manually rotated to press the valve seat 4 to prevent the valve seat 4 from being offset during the rotation of the disc 15. The plane on the disc 15 rotates to be away from the support groove 21. At this time, the disc 15 partially rotates into the arc groove 41 of the valve seat 4. The disc 15 presses the valve seat 4 to prevent the valve seat 4 from being separated from the support groove 21. As the disc 15 rotates, the lifting ring 1 is driven to descend. When the lifting ring 1 descends to the lowest position, the top surface of the lifting ring 1 is flush with the top surface of the support sleeve 23. When the valve core is pressed onto the valve seat 4, the lifting ring 1 protects the support sleeve 23 to prevent the support sleeve 23 from being deformed. The bottom surface of the lifting ring 1 is lower than the bottom surface of the support sleeve 23. The gas in the support sleeve 23 is extracted through the air source. Since the air source is evacuated quickly, the original air pipe will be aligned with the bottom surface of the support sleeve 23. The lifting ring 1 bends when in contact with the lifting ring 1. In this embodiment, since the bottom surface of the lifting ring 1 is lower than the bottom surface of the supporting sleeve 23, the position where the air pipe contacts the lifting ring 1 is bent, so that the curvature of the air pipe bending is reduced, thereby preventing the air pipe from being unable to ventilate due to bending, and ensuring the effect of air extraction. During the air extraction process, if the thickness of the protruding portion of the bottom surface of the valve seat 4 is uniform, the inner chamber 25 is in a sealed state, the inner chamber 25 is not connected to the outer chamber 26, the gas in the outer chamber 26 will not be extracted, and the lifting ring 1 will not rise. If the thickness of the protruding portion of the bottom surface of the valve seat 4 is uneven, the protruding portion cannot completely contact with the top surface of the supporting sleeve 23, and the inner chamber 25 is connected to the outer chamber 26. At this time, when the gas in the inner chamber 25 is extracted, it will lead to As a result, the gas in the outer chamber 26 is also extracted, and a negative pressure is formed in the outer chamber 26, causing the lifting ring 1 to rise. During the rising process of the lifting ring 1, the column 11 moves in the spiral groove 17 and then drives the rotating block 16 to rotate, so that the rotating shaft 14 of the disc 15 does not press the valve seat 4. During the rising process of the lifting ring 1, the positioning column 13 is reinserted into the groove on the bottom surface of the valve seat 4. When the lifting ring 1 rises to the highest point, the valve seat 4 is lifted up. At this time, it is judged that the thickness of the bottom surface of the valve seat 4 is unqualified. The highest position of the lifting ring 1 is higher than the position of the lifting ring 1 in the initial state, and when the lifting ring 1 rises to the highest position, the disc 15 will not rotate into the arc groove 41, so as to avoid the disc 15 from hindering the lifting of the valve seat 4.

[0074] In an optional embodiment, a stamping mechanism is arranged above the supporting mechanism, and the stamping mechanism includes: a three-axis moving component 3 and a stamping head 31; the stamping head 31 is arranged on the three-axis moving component 3; the three-axis moving component 3 is suitable for driving the stamping head 31 to move; the stamping head 31 is suitable for stamping the valve core on the valve seat 4; the three-axis moving component 3 can make the stamping head 31 align with the valve seat 4 and press the valve core onto the valve seat 4.

[0075] At least one other disclosed embodiment also provides a working method using the above-mentioned ASU stamping device, including: after the support mechanism supports the valve seat 4, the gas in the inner chamber 25 is extracted outwardly, if the bottom surface of the valve seat 4 is uneven, the inner chamber 25 is connected to the outer chamber 26, and as the gas in the inner chamber 25 is extracted, the lifting ring 1 moves upward to lift the valve seat 4 through the positioning column 13.

[0076] In summary, the stamping device for ASU includes: a supporting mechanism and a detecting mechanism; the detecting mechanism is arranged in the supporting mechanism, the supporting mechanism is suitable for supporting the valve seat 4, the detecting mechanism contacts the bottom surface of the valve seat 4, and the detecting mechanism is suitable for detecting whether the thickness of the bottom surface of the valve seat 4 is uniform; wherein the detecting mechanism includes: a lifting ring 1; the lifting ring 1 is slidably connected to the supporting mechanism, and the positioning column 13 on the top surface of the lifting ring 1 is inserted into the bottom surface of the valve seat 4; after the supporting mechanism supports the valve seat 4, the supporting mechanism and the valve seat 4 form an inner chamber 25 and an outer chamber 26, and the lifting ring 1 is slidably arranged in the outer chamber 26, at which time the gas in the inner chamber 25 is extracted outwardly, if the thickness of the bottom surface of the valve seat 4 is uneven, the inner chamber 25 is connected to the outer chamber 26, and as the gas in the inner chamber 25 is extracted, the lifting ring 1 moves upward through the positioning column 13 to lift the valve seat 4; the detection of the bottom surface thickness of the valve seat 4 is realized to ensure the quality of the final product.
