Description

Technical Field

[0001] The utility model relates to the technical field of sealing ring detection, in particular to a detection tool for stable detection of sealing rings. Background Art

[0002] Sealing rings are suitable for hydraulic and pneumatic systems and various mechanical equipment and components. They play a sealing role in liquid and gas media in static or moving states. Among the sealing rings, O-rings are the most commonly used. O-rings are the most widely used seals on various mechanical equipment. They have an extremely simple cross-sectional structure and are self-sealing with reliable sealing performance. They are mainly used for static sealing and reciprocating motion sealing. O-rings need to be quality inspected after production to eliminate unqualified products.

[0003] When the existing O-ring air tightness detection mechanism is performing detection, once the existence of a leak is confirmed, the leak cannot be quickly located to confirm the cause of the leak, and the O-ring needs to be removed and reprocessed, which is complicated to operate and inconvenient to use. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a sealing ring stability detection fixture, which solves the above-mentioned problems.

[0005] To achieve the above purpose, the utility model is implemented through the following technical solutions: a kind of inspection tool for sealing ring stability detection, including an inspection platform and a side plate fixed on the top of the inspection platform, one side of the side plate is fixedly connected with a driving cylinder, the bottom end of the driving cylinder piston rod is fixedly connected with an upper extrusion plate through a connecting tube, a sliding groove for the sealing ring to slide into is opened on the surface of the inspection platform, a lower lifting plate driven by a cylinder is embedded below the sliding groove, the inner cavity of the connecting tube is connected with an air pipe connected with an external air source, the bottom of the connecting tube is connected with the inner cavity of the upper extrusion plate, and a pressure detection component is embedded on the surface of the lower lifting plate;

[0006] The surface of the detection platform is provided with a display mechanism, which includes a rotating circle rotatably arranged on the surface of the detection platform, the inner cavity of the rotating circle is respectively provided with a foam output hole connected with the foam source through a foam tube and an air flow output hole connected with the air source through an air inlet pipe, the surface of the detection platform is rotatably connected with a driving gear driven by a motor, and the surface of the rotating circle is fixedly connected with a rack meshing with the surface of the driving gear. When in use, the sealing ring is slid to the top of the lower lifting plate through the sliding groove, and then the sealing ring is clamped by the clamping ring for positioning, and then the lower lifting plate lifts the sealing ring, and then the upper extrusion plate presses down to squeeze the sealing ring, and then air is injected into the sealing ring through the air pipe into the connecting cylinder, and the lower lifting plate is pressed. The built-in pressure detection component detects the air pressure. When a decrease in air pressure is detected, it is determined that there is an air leak. At this time, the sealing ring is moved between the rotating circles by adjusting the positions of the upper extrusion plate and the lower lifting plate. The rotating circle is then rotated to drive the foam output hole to blow out foam to the top of the sealing ring. The leakage point is then detected by the state of the bubbles. After the detection is completed, air flow is output through the air flow output hole to blow away the bubbles for cleaning. The upper extrusion plate and the lower lifting plate are reset to take out the sealing ring for the next one to be tested. After detecting that the sealing ring is leaking, the leakage point can be quickly detected. The foam can be effectively cleaned after rapid positioning by foam spraying. The operation is simple and convenient, and there is no need to re-detect and locate the leakage point later.

[0007] As a further solution of the utility model: the inner cavity of the upper extrusion plate is provided with a through-center groove, through which the airflow blown out of the air pipe can be guided to the center of the sealing ring.

[0008] As a further solution of the utility model: the foam output holes and the airflow output holes are both provided in multiple numbers and are symmetrically distributed on both sides of the inner circle of the rotating circle. The rotating circle rotates to drive the foam output holes to blow out foam to the top of the sealing ring, and then the leakage point is detected by the state of the bubbles. After the detection is completed, the airflow is output through the airflow output holes to blow away the bubbles for cleaning, and then the sealing ring is output for subsequent processing.

[0009] As a further solution of the utility model: the rotating ring is located between the upper extrusion plate and the lower lifting plate, and the inner diameter is 1.5 times that of the sealing ring.

[0010] As a further solution of the utility model: a clamping ring driven by a cylinder is built into the inner cavity of the sliding groove, the sealing ring is clamped by the clamping ring for positioning, and then lifted up by the lower lifting plate and extruded by the upper extrusion plate.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. The utility model, when the air pressure is detected to be reduced, it is judged that there is a leak. At this time, the sealing ring is moved between the rotating circles by adjusting the positions of the upper extrusion plate and the lower lifting plate. The rotating circle is then rotated to drive the foam output hole to blow out foam to the top of the sealing ring. The leakage point is then detected by the state of the bubbles. After the detection is completed, the air flow is output through the air flow output hole to blow away the bubbles for cleaning. The upper extrusion plate and the lower lifting plate are reset to take out the sealing ring for the next one to be tested. After the leakage of the sealing ring is detected, the leakage point can be quickly detected. The foam can be effectively cleaned after rapid positioning by foam spraying. The operation is simple and convenient, and there is no need to re-detect and locate the leakage point later.

[0013] 2. The utility model has multiple foam output holes and airflow output holes, which are symmetrically distributed on both sides of the inner circle of the rotating circle. Multiple operations can be performed by simply rotating the rotating circle. The structure is simple and easy to use. BRIEF DESCRIPTION OF THE DRAWINGS
