Description

Technical Field

[0001] This utility model belongs to the field of detection technology for the front and back of V-groove sealing rings, specifically relating to a device for detecting the front and back of V-groove sealing rings. Background Technology

[0002] V-groove seals are widely used. Due to their unique V-shaped design, V-groove seals effectively prevent leakage of liquids, gases, and particles from gaps, and are widely used in various mechanical equipment such as reciprocating motion sealing devices and rotary shaft sealing devices. The cross-section of a V-groove seal is V-shaped, and the inner diameter differs between the positive and negative axial ends. During use, V-groove seals are designed to provide a seal in a specific direction. When installed incorrectly, the sealing performance can be severely affected, leading to fluid leakage. This not only wastes resources but may also cause equipment instability and increase maintenance costs.

[0003] During on-site operations, it is necessary to determine the orientation of the V-groove seal. Currently, this is often done manually, which is inefficient and prone to errors due to the high labor intensity.

[0004] Therefore, it is necessary to design a detection device for the positive and negative orientation of V-groove seals to improve operational efficiency. Utility Model Content

[0040] In the accompanying drawings, the same parts use the same reference numerals. The drawings are not drawn to scale. Detailed Implementation

[0041] To make the technical solution and advantages of this utility model clearer, the exemplary embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not an exhaustive list of all embodiments. Furthermore, without conflict, the embodiments and features in the embodiments of this utility model can be combined with each other.

[0042] An embodiment of this utility model provides a device for detecting the positive and negative orientation of a V-groove sealing ring. For example... Figures 1 to 5As shown, the detection device for the positive and negative orientation of a V-groove seal ring includes a support platform (not shown), a first support member 1, a probe 2, a first proximity sensor 3, an elastic reset member 4, a second support member 5, a second proximity sensor 6, and a first driver 7. The support platform serves as the basic support for this detection device, primarily supporting the other components. The first support member 1 is mounted on the support platform. A first mounting hole 11 is provided on the first support member 1. The first mounting hole 11 extends vertically. The probe 2 is fitted into the first mounting hole 11 and can move vertically relative to the first support member 1. The lower end of the probe 2 is a cone 21. This cone 21 is used to insert into the inner cavity of the V-groove seal ring. The first proximity sensor 3 is fixedly mounted in the first mounting hole 11. Simultaneously, the first proximity sensor 3 is located above the probe 2 and is used to sense the approach of the probe 2. When the distance between the probe 2 and the first proximity sensor 3 reaches a preset range, the first proximity sensor 3 generates a signal. An elastic reset member 4 is disposed between the probe 2 and the first support member 1. During the movement of the probe 2 relative to the first support member 1, it generates resistance and accumulates energy, causing the probe 2 to reset. A first driver 7 is disposed between the support platform and the first support member 1, used to drive the first support member 1 to move vertically relative to the support platform, thereby driving the probe 2 to move. The upper end surface of the second support member 5 forms a sealing ring mounting surface 51, used as a mounting surface for placing a V-groove sealing ring. That is, the V-groove sealing ring to be tested can be placed on the second support member 5. A second mounting hole 52 is provided on the second support member 5. The axial direction of the second mounting hole 52 extends vertically. Furthermore, the upper end of the second mounting hole 52 communicates with the sealing ring mounting surface 51. That is, the opening of the second mounting hole 52 is located on the sealing ring mounting surface 51. A second proximity sensor 6 is fixedly sleeved within the second mounting hole 52. Furthermore, the second proximity sensor 6 is located at the lower end of the second mounting hole 52.

[0043] During the operation of the detection device for the front and back of the V-groove seal ring, the V-groove seal ring 200 to be detected is placed on the seal ring mounting surface 51 of the second support member 5. At this time, the inner cavity of the V-groove seal ring 200 is vertically connected to the second mounting hole 52. Then, the first driver 7 is activated, actuating the first support member 1 and causing the probe 2 to move downwards. The probe 2 approaches and penetrates into the inner cavity of the V-groove seal ring 200. Because the inner cavity of the V-groove seal ring 200 is a frustum-shaped hole, the depth of insertion of the cone 21 into the inner cavity of the V-groove seal ring will differ depending on whether it is inserted from the back or the front. Therefore, the position of the probe 2 will also be different accordingly. Specifically, the probe 2 will either be closer to the first proximity sensor 3 or closer to the second proximity sensor 6. If it is closer to the first proximity sensor 3, such as... Figure 4As shown, the V-groove seal ring is difficult to insert deeper; that is, the probe 2 encounters greater resistance during insertion. This force can cause the probe 2 to move upward relative to the first support 1, approaching the first sensor 3, and causing the first proximity sensor 3 to send a signal indicating that the V-groove seal ring is in the reverse direction (the smaller end of the inner diameter of the V-groove seal ring is facing upward). During this process, the elastic reset member 4 is compressed and accumulates its capacity so that after the first driver moves the first support 1 upward, it causes the probe 2 to move downward relative to the first support 1 for reset. If it gets closer to the second proximity sensor 6, such as... Figure 5 As shown, the V-groove seal ring is easier to insert deeper, so the probe 2 gets closer to the second proximity sensor 6. The second proximity sensor 6 then sends a signal indicating that the V-groove seal ring is in the positive orientation (the larger end of the V-groove seal ring's inner diameter is facing upwards). Therefore, the detection device for the positive and negative orientation of the V-groove seal ring can easily determine its orientation, freeing up manpower, improving detection efficiency, and increasing detection accuracy.

[0044] In one embodiment, the first support member 1 includes a first connecting plate 12, a second connecting plate 13, and a third connecting plate 14. The first connecting plate 12 is also connected to the first driver 7 and is L-shaped. The second connecting plate 13 is vertically spaced opposite to one side of the first connecting plate 12. The third connecting plate 14 connects the first connecting plate 12 and the second connecting plate 13, mainly serving a connecting function. The first mounting hole 11 passes through the first connecting plate 12 and the second connecting plate 13 in sequence. A radial extension 22 is provided on the outer wall of the probe 2. After installation, the radial extension 22 is located between the first connecting plate 12 and the second connecting plate 13. An elastic reset member 4 is disposed between the radial extension 22 and the first connecting plate 12. Preferably, the elastic reset member 4 is a spring. The spring is sleeved on the outer wall of the probe 2, and its upper and lower ends abut against the first connecting plate 12 and the radial extension 22, respectively. The above-described structure is optimized and easy to implement.

[0045] The first actuator 7 is a lifting cylinder, used to drive the first support member 1 to move up and down. This setup is simple and easy to implement.

[0046] A gripper assembly is also provided on the support platform. The gripper assembly includes a gripper 91, a gripper drive cylinder 92, a tilting cylinder 93, a second drive cylinder 94, and a third drive cylinder 95. The gripper 91 extends horizontally, with its opening facing the second support member 5, for picking up the V-groove seal ring. The gripper drive cylinder 92 drives the gripper 91 to open to release or prepare to pick up the V-groove seal ring, or drives the gripper 91 to clamp to hold the V-groove seal ring. The tilting cylinder 93 drives the gripper drive cylinder 92 to tilt around the length of the gripper 91. For example, the tilting cylinder 93 can rotate 180 degrees clockwise or counterclockwise to drive the gripper drive cylinder 92, thereby tilting the gripper 91 to flip the V-groove seal ring. The second drive cylinder 94 drives the tilting cylinder 93 to move vertically. The second drive cylinder 94 is a lifting cylinder. The position of the gripper 91 in the vertical direction can be adjusted by setting the second drive cylinder 94. The third drive cylinder 95 is used to drive the second drive cylinder 94 to move in the horizontal direction, thereby making the gripper 91 move closer to or away from the V-groove seal ring.

[0047] A cover plate 53 is provided on the upper surface of the second support member 5. The cover plate 53 is spaced apart from the sealing ring mounting surface 51. A feed port 54 is formed between the cover plate 53 and the sealing ring mounting surface 51. An open groove 55 is provided on the cover plate 53. The open groove 55 and the feed port 54 are located at opposite ends in the horizontal direction. At the same time, the open groove 55 is opposite to the second mounting hole 52. In use, the V-groove sealing ring enters the sealing ring mounting surface 51 of the second support member 5 through the feed port 54. It can be seen that the cover plate 53 vertically defines the position of the V-groove sealing ring, which can ensure that the V-groove sealing ring enters from either the front or the back. When the V-groove sealing ring is positioned opposite the open groove 55, the probe 2 can pass through the open groove 55 and penetrate into the inner cavity of the V-groove sealing ring. To facilitate the insertion of probe 2, the width of the open groove 55 must be greater than the inner diameter of the V-groove sealing ring. To facilitate the removal of probe 2 from the V-groove sealing ring and prevent the V-groove sealing ring from moving together with probe 2, the width of the open groove 55 must be smaller than the outer diameter of the V-groove sealing ring, so that the cover plate 53 can limit the V-groove sealing ring.

[0048] A color sensor 56 is provided on the second support member 5. The color sensor 56 is used to detect whether the V-groove sealing ring is in place. Specifically, when the V-groove sealing ring reaches the preset position, that is, directly above the second mounting hole 52 and directly below the probe 2, the color sensor 56 indicates that the V-groove sealing ring is in place.

[0049] A baffle 10 is provided at the open end of the open slot 55 of the cover plate 53. The baffle 10 is connected to the support platform via a fourth drive cylinder 8. The fourth drive cylinder 8 is used to drive the baffle 10 to move vertically. The fourth drive cylinder 8 is a lifting cylinder. The baffle 10 is located away from the feed port 54, which can be referred to as the extended discharge port 57, and is used to limit the position of the V-groove sealing ring to prevent the V-groove sealing ring from falling off. The fourth drive cylinder 8 can drive the baffle 10 to a blocking position or an avoidance position, thereby positioning the V-groove sealing ring or making it removable.

[0050] The detection device for the positive and negative orientation of V-groove seals also includes a V-groove seal discharge mechanism 20. The discharge port (not shown in the figure) of the V-groove seal discharge mechanism 20 is connected to the inlet 54 for supplying V-groove seals. For example, the second support member 5 can be fixed to the outer wall of the V-groove seal discharge mechanism 20. In this application, a V-groove seal discharge mechanism 20 from the prior art is utilized; for example, this V-groove seal discharge mechanism 20 can be a V-groove seal discharge mechanism manufactured by Hengyuan Manufacturing Machinery Plant in Dalian Economic and Technological Development Zone.

[0051] The following is based on Figures 1 to 4 This document describes in detail the process of detecting the front and back of a V-groove seal using a detection device for V-groove seals.

[0052] First, the device enters the preparatory state. At this time, the V-groove sealing ring is placed inside the V-groove sealing ring discharge mechanism 20, ready for discharge. The baffle 10, driven by the fourth drive cylinder 8, reaches the position to block the extended discharge port 57. The first drive cylinder 7 moves, actuating the first support member 1 to adjust the position of the probe 2, so that the probe 2 is positioned directly above the second mounting hole 52, ready for insertion. At this point, the gripper 91, controlled by the third drive cylinder 95, moves away from the extended discharge port 57.

[0053] Then, the discharge operation is performed. The V-groove seal ring in the V-groove seal ring discharge mechanism 20 is discharged through the discharge port. The V-groove seal ring enters between the cover plate 53 and the seal ring mounting surface 51 through the feed port 54 and is located on the seal ring mounting surface 51. As the V-groove seal ring moves horizontally towards the extended discharge port 57, it gradually approaches the baffle 10. Under the action of the baffle 10, the V-groove seal ring is prevented from falling off the seal ring mounting surface 51. The color sensor 56 operates. If the V-groove seal ring is in place, it provides an indication. At this time, the V-groove seal ring is located directly above the second mounting hole 52 and directly below the probe 2.

[0054] Next, the probe probes and detects the orientation of the V-groove seal. Specifically, the first actuator 7 drives the first support 1 downward, which in turn drives the probe 2 downward. With the drive of the first actuator 7, the probe 2 inserts into the V-groove seal. Through the operation of the first proximity sensor 3 and the second proximity sensor 6, if the first proximity sensor 3 sends a signal, it indicates that the V-groove seal is in the reverse orientation; if the second proximity sensor 6 sends a signal, it indicates that the V-groove seal is in the forward orientation.

[0055] Finally, the V-groove seal ring is moved to the next position. According to the specifications for the next position, if the V-groove seal ring needs to be facing upwards in the front position, then the V-groove seal ring facing upwards on the seal ring mounting surface 51 is moved directly, while the V-groove seal ring facing downwards on the seal ring mounting surface 51 is flipped and moved. Conversely, if the next position requires a reversed V-groove seal ring, then the reversed V-groove seal ring is moved directly, while the front V-groove seal ring is flipped and moved.

[0056] When the V-groove seal ring can be directly transported without needing to be flipped, the first actuator 7 drives the probe 2 upward. The fourth actuator 8 drives the baffle 10 downward, releasing its blocking effect on the V-groove seal ring. At this time, the V-groove seal ring is in a pick-upable state. Then, the third actuator 95 moves the gripper 91 close to the V-groove seal ring. The gripper actuator 92 is activated to actuate the gripper 91 to clamp the V-groove seal ring. Then, the third actuator 95 moves the gripper 91 away from the second support member 5, and transports the V-groove seal ring to the next work station.

[0057] When the V-groove seal needs to be flipped, the first driver 7 drives the probe 2 upward. The fourth drive cylinder 8 drives the baffle 10 downward, releasing the blocking effect on the V-groove seal. At this time, the V-groove seal is in a pick-upable state. Then, the third drive cylinder 95 moves the gripper 91 close to the V-groove seal. The gripper drive cylinder 92 is activated to actuate the gripper 91 to clamp the V-groove seal. The third drive cylinder 95 then moves the gripper 91 away from the second support member 5. The second drive cylinder 94 extends. The flipping cylinder 93 moves to move the V-groove seal. The second drive cylinder 94 extends and retracts. At this time, the V-groove seal is flipped to the required surface. The V-groove seal is then transported to the next workstation.

[0058] In this application, the detection device for the positive and negative orientation of the V-groove sealing ring has a simple structure and is easy to operate; it can determine the positive and negative orientation of the V-groove sealing ring through a proximity sensor, and has high working efficiency.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and / or modifications falling within the scope of the present invention, and all changes and / or modifications made according to the embodiments of the present invention should be covered within the protection scope of the present invention.
