[0027] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0028] like Figures 1-5 As shown, a device for detecting the curvature and warpage of a sealing ring includes a detection base 1. The detection base 1 has two opposing semicircular disks 2. The top side of each semicircular disk 2 has a placement opening 3, and the edge of the placement opening 3 has a pre-installation opening 4. When the two semicircular disks 2 are combined, the two pre-installation openings 4 form a pre-installation hole 5. A pre-installation rod 6 for inserting the sealing ring is provided in the pre-installation hole 5. The detection base 1 has a drive mechanism 7 for driving the two semicircular disks 2 to move synchronously in opposite directions. The detection base 1 also has a detection cylinder 8. The detection cylinder 8 has a detection channel 9 that is directly opposite to the placement opening 3. The bottom end of the pre-installation rod 6 extends into the detection channel 9. The detection cylinder 8 has a bending detection mechanism 10 for detecting the curvature of the sealing ring. A warpage detection mechanism 11 is also provided between the detection cylinder 8 and the bending detection mechanism 10.

[0029] As shown in Figures 1-5 the test, the two half-discs 2 are driven to merge by the driving mechanism 7, the sealing ring to be tested is placed in the placement opening 3, the preloading rod 6 is inserted into the preloading hole 5, and the sealing ring to be tested is sleeved on the preloading rod 6, so that the bottom of the sealing ring abuts against the bottom surface of the placement opening 3; then the two half-discs 2 are driven to separate by the driving mechanism 7, the sealing ring falls into the detection channel 9, and then sequentially passes through the bending detection mechanism 10 and the warping detection mechanism 11 for detection; the sealing ring to be tested with qualified bending degree flows to the warping detection mechanism 11, and the sealing ring to be tested with unqualified bending degree is directly discharged; the sealing ring to be tested with qualified bending degree is detected by the warping detection mechanism 11, and finally the sealing ring to be tested with qualified warping degree and bending degree and the sealing ring to be tested with only unqualified warping degree are discharged, so as to facilitate classification and processing of the sealing ring to be tested, effectively improve the detection and feeding effect of the sealing ring, facilitate collection, fast detection, and high accuracy; the preloading rod 6 is arranged to guide the movement of the sealing ring, avoid the sealing ring to be tested from impacting the inner wall of the detection channel 9, and accelerate the flow speed of the sealing ring, so that the sealing ring can be sequentially detected in terms of bending degree and warping degree, the detection cost of the sealing ring is reduced, and the detection effect is improved.

[0030] As shown in Figure 3 in the embodiment, the driving mechanism 7 includes an electric cylinder 71, a guide rail 72, a driving frame 73, and a driving groove 74; the electric cylinder 71 is arranged on the detection seat 1; the guide rail 72 is arranged on the detection seat 1 and parallel to the electric cylinder 71; the middle part of the driving frame 73 is fixedly connected with the output end of the electric cylinder 71; the two ends of the driving frame 73 are respectively slidably connected with the guide rail 72; the two ends of the driving frame 73 are provided with driving columns 731; the number of the driving grooves 74 is two and the driving grooves 74 are symmetrically arranged at the bottom of the half-disc 2; the driving grooves 74 have a V-shaped structure and the tip of the V-shaped structure faces the preloading opening 4; the connecting line at the two ends of the V-shaped structure is parallel to the extension direction of the guide rail 72; and the driving column 731 is slidably fitted in the driving groove 74, so that when the driving column 731 moves to the tip of the driving groove 74, the sealing ring falls into the detection channel 9.

[0031] The driving frame 73 is driven by the electric cylinder 71 to move along the guide rail 72, and the driving column 731 is driven to slide in the driving groove 74; when the two half-discs 2 merge, the driving column 731 is located at the end of the driving groove 74; when the driving column 731 slides to the tip of the V-shaped structure of the driving groove 74, the two half-discs 2 are separated from each other; the driving frame 73 is continuously driven by the electric cylinder 71 to move in the same direction, so as to make the two half-discs 2 merge again; the structure is compact, the two half-discs 2 can be quickly and synchronously merged and separated, the moving accuracy is high, the two ends of the sealing ring can be simultaneously lost in support, the two ends of the sealing ring are uniformly stressed, the sealing ring can stably fall into the detection channel 9 along the preloading rod 6, and the falling speed of the sealing ring is improved.

[0032] As Figures 1-5 shown in the embodiment, the bending detection mechanism 10 comprises a bending cylinder 101, a bending hole 102, a non-bending opening 103, and a rotating assembly 104. The bending cylinder 101 is rotationally connected with the bottom end of the detection cylinder 8. The bending hole 102 is coaxially arranged at the bottom of the bending cylinder 101. The diameter of the bending hole 102 is the same as the rated detection diameter of the sealing ring, and the rated detection diameter is the same as the minimum diameter of the sealing ring. A centrifugal arc surface with a small upper part and a large lower part is arranged in the middle of the inner wall of the bending cylinder 101. The non-bending opening 103 is arranged on the centrifugal arc surface. The rotating assembly 104 is arranged between the bending cylinder 101 and the warping detection mechanism 11 and is used to drive the bending cylinder 101 to rotate.

[0033] As Figure 2 , 4 shown, the sealing ring with the same diameter as the diameter of the bending hole 102 is a qualified product, so that it is left to the warping detection mechanism 11 through the bending hole 102. Since the rated detection diameter is the same as the minimum diameter of the sealing ring, it is convenient to accurately screen the bending degree of the sealing ring with the smallest diameter. The end of the sealing ring to be detected that does not meet the requirements is inserted into the centrifugal arc surface. At this time, the preloading rod 6 is pulled out, and the rotating assembly 104 is driven to drive the bending cylinder 101 to rotate. Under the action of the centrifugal force, the sealing ring with the qualified bending degree is discharged from the non-bending opening 103.

[0034] As Figure 2 , 4 shown in the embodiment, the rotating assembly 104 comprises a rotating motor 1041, a rotating gear 1042, and a connecting gear 1043. The mounting end of the rotating motor 1041 is fixedly connected to the warping detection mechanism 11. The output end of the rotating motor 1041 is coaxially fixedly connected with the rotating gear 1042. The connecting gear 1043 is coaxially fixedly connected to the outside of the bending cylinder 101. The rotating gear 1042 is fixedly connected with the connecting gear 1043.

[0035] As Figure 2 shown, the rotating motor 1041 drives the rotating gear 1042 to rotate, and the bending cylinder 101 is driven to rotate under the action of the rotating gear 1042 and the connecting gear 1043. It is convenient to automatically drive the bending cylinder 101 to rotate. The rotating motor 1041 is a servo motor, which effectively controls the rotation accuracy and rotation speed of the bending cylinder 101. Increasing the rotation speed of the rotating motor 1041 can shorten the test time of the sealing ring.

[0036] As Figure 2As shown, in this embodiment, the warpage detection mechanism 11 includes a warpage cylinder 111, a warpage cavity 112, a warpage opening 113, a defective product opening 114, a warpage block 115, and a lifting assembly 116. The warpage cylinder 111 is rotatably connected to the bending cylinder 101. The mounting end of the rotating motor 1041 is fixedly connected to the warpage cylinder 111. The top end of the warpage cavity 112 has a warpage hole 1121 corresponding to the bending hole 102. The warpage opening 113 is obliquely penetrating through the warpage cavity 111. The side wall of 2 has the bottom end of the warped opening 113 facing outward from the warped cylinder 111. The top surface of the warped block 115 is inclined and flush with the bottom surface of the warped opening 113. The defective opening 114 is opened through the warped cylinder 111 and extends in a direction parallel to the warped opening 113. The defective opening 114 is located below the warped opening 113. The lifting assembly 116 is located inside the warped cylinder 111 and is used to drive the warped block 115 to move longitudinally between the defective opening 114 and the warped opening 113.

[0037] The test sealing ring with qualified curvature is located on the top surface of the warping block 115 after passing through the bending hole 102 and the warping hole 1121. Since the bottom end of the warping opening 113 faces outward from the warping cylinder 111, and the top surface of the warping block 115 is inclined and flush with the bottom surface of the warping opening 113, the test sealing ring with qualified curvature can be directly discharged from the bottom end of the warping opening 113. The test sealing ring with unqualified curvature accumulates at the inner end opening of the warping opening 113, and is then lifted to the defective product opening 114 by the lifting component 116. Since the defective product opening 114 is opened through the warping cylinder 111 and extends in a direction parallel to the warping opening 113, it is convenient to smoothly send the test sealing ring with unqualified curvature and curvature to the defective product opening 114 and discharge it.

[0038] In this embodiment, the lifting component 116 is a lifting cylinder. The mounting end of the lifting cylinder is fixedly installed on the bottom surface of the inner wall of the warping cylinder 111. The output end of the lifting cylinder is fixedly connected to the warping block 115. The extension and retraction distance of the lifting cylinder is equal to the distance between the defective port 114 and the warping port 113.

[0039] like Figure 2 As shown, the lifting cylinder drives the warp block 115 to move up and down. Since the extension and retraction distance of the lifting cylinder is equal to the distance between the defective port 114 and the warp port 113, it prevents the bottom of the top surface of the warp block 115 from being lower than the bottom of the opening of the defective port 114, thus preventing the test sealing ring, which has failed to meet the requirements of warp and curvature, from being bumped and ensuring the integrity of the test sealing product.

[0040] In this embodiment, a protective cylinder 12 is fixedly connected to the warp cylinder 111. The inner side of the protective cylinder 12 is rotatably connected to the outer side of the warp cylinder 111. The outer end of the non-bend 103 abuts against the inner side of the protective cylinder 12. The protective cylinder 12 is provided with an outlet 13 corresponding to the non-bend 103. The protective cylinder 12 is also provided with a guide ring cover 14 with an open bottom end. One end of the outlet 13 passes through the guide ring cover 14.

[0041] When the bending cylinder 101 rotates, the test sealing rings that fail to meet the bending requirements flow through the non-bend 103 and the outlet 13 into the guide ring cover 14, and then flow out from the bottom of the guide ring cover 14, preventing the test sealing rings from splashing. The rotation component 104 can control the speed and time of the rotation motor 1041, stopping when the test sealing rings that fail to meet the bending requirements are located at the connection between the non-bend 103 and the outlet 13. Under the action of centrifugal force, the test sealing rings are retained in the guide ring cover 14, preventing the test sealing rings from being subjected to additional collisions. This not only ensures the accuracy of the bending test, but also improves the product integrity of the test sealing rings, facilitating subsequent processing.

[0042] All technical features in this embodiment can be freely combined according to actual needs.

[0043] The above embodiments are preferred implementations of the present invention. In addition, other implementations are also included. Any obvious substitutions without departing from the concept of the present invention are within the protection scope of the present invention.
