Description

Technical Field

[0001] This invention relates to the field of rubber product testing, and more particularly to a testing device for automotive rubber production. Background Technology

[0002] As an important component of automotive piping systems, automotive rubber corrugated hoses are widely used in ventilation, water supply, and oil and gas transportation. Their retraction and recovery performance and pipe wall integrity are key indicators to ensure the normal operation of the pipeline. After production, the industry generally uses inflation to test the corrugated hoses: on the one hand, compressed air is used to expand the corrugated hose, and after depressurization, it naturally contracts to test its retraction and recovery effect; on the other hand, after the corrugated hose is inflated and expanded, the folds of the pipe wall are fully unfolded, making it easier for operators to observe the appearance of the pipe wall and check for surface defects such as cracks and holes. This testing method is simple to operate and is now widely used.

[0003] However, the existing inflation testing process has obvious safety defects, which seriously affect the normal operation of the testing work. During the testing process, compressed air is injected into the corrugated pipe. If the corrugated pipe itself has material defects (such as uneven wall thickness, hidden cracks, etc.), it is very easy to break under inflation and pressure. When the corrugated pipe breaks, the high-pressure gas inside is released rapidly, which will form a high-speed jet of air. This airflow can not only cause impact injury to on-site personnel, but the rubber fragments generated by the breakage will also be splashed along with the airflow, further aggravating the safety risks. Summary of the Invention

[0004] In order to overcome the shortcomings of existing air-filled testing equipment and processes for corrugated pipes, such as the high-speed airflow after rupture easily causing safety accidents and poor testing safety, this invention provides a testing device for automotive rubber production.

[0005] The technical solution is as follows: a testing device for automotive rubber production, comprising a workbench; a bracket mounted on the workbench; an industrial microscope mounted on the bracket; a display screen mounted on the workbench; the industrial microscope and the display screen being electrically connected; a connecting assembly mounted on the workbench; two symmetrical clamping blocks connected to the workbench; each clamping block being mounted on the connecting assembly; a clamping assembly for clamping bellows connected to each clamping block; a first airbag installed between the two clamping blocks; a cylindrical lamp installed inside the first airbag; a connector connected to the connecting assembly; a first rotating ring rotatably connected to the clamping block on the left side, forming a first cavity between the first rotating ring and the clamping block, and a first connecting pipe connected to the first rotating ring; the first connecting pipe communicating with the first cavity; an air inlet groove formed on the clamping block on the left side; the first cavity communicating with the first airbag through the air inlet groove.

[0006] Furthermore, the connecting assembly includes a servo motor connected to the worktable; a connecting rod is fixedly connected to the output end of the servo motor; a clamping block on the left side is fixedly connected to the connecting rod, and an electric push rod is fixedly connected to the worktable; a connector is fixedly connected to the telescopic end of the electric push rod; a connecting end is provided on the clamping block on the right side; the connecting end is rotatably connected to the connector; a limiting groove is provided inside the connecting rod; a sliding rod is slidably connected inside the limiting groove; a sliding head is fixedly connected to the left side of the sliding rod; a spring is fixedly connected between the sliding head and the connecting rod; a cylindrical light is installed on the outside of the sliding rod; a conductive slot is provided on the right side of the sliding rod; a conductive plug is fixedly connected to the connector, and the conductive plug is inserted into the conductive slot; a retaining ring is fixedly connected to the sliding rod; one end of the first airbag is fixedly connected to the clamping block on the left side, and the other end is fixedly connected to the retaining ring; an electromagnet is fixedly connected to the retaining ring; the electromagnet is magnetically attracted and fixed to the clamping block on the right side; both the cylindrical light and the electromagnet are electrically connected to the conductive slot.

[0007] Furthermore, the clamping assembly includes a second airbag connected to the clamping block; a second rotating ring is rotatably connected to each clamping block; a second cavity is formed between each second rotating ring and the clamping block; a second connecting tube is connected to each second rotating ring; each second connecting tube is connected to the corresponding second cavity; each second cavity is connected to the second airbag; the first and second rotating rings on the left clamping block are fixed to the worktable; the second rotating ring on the right clamping block is fixed to the connector.

[0008] Furthermore, the first airbag is made of highly transparent silicone material.

[0009] Furthermore, the second airbag is made of fluororubber and has a roughened surface.

[0010] Furthermore, the length of the cylindrical lamp is greater than the length of the corrugated tube in its maximum tensile state; it can completely cover the internal area of ​​the corrugated tube, avoiding localized light loss that could interfere with subsequent testing.

[0011] Furthermore, the cylindrical lamp is covered with an explosion-proof transparent cover, which can buffer the squeezing effect of air pressure on the cylindrical lamp and prevent the cylindrical lamp from being damaged by pressure.

[0012] Furthermore, it also includes contact rings; several contact rings are fixedly connected inside the conductive slot; each contact ring is in close contact with the conductive plug.

[0013] By adopting the above structure, the copper contact ring exhibits excellent conductivity, and the multiple sets of contact points enhance circuit connection stability, preventing power outages and poor contact during equipment operation.

[0014] Furthermore, it also includes a supplemental light that connects to the industrial microscope.

[0015] Furthermore, it also includes a light shield that connects to an industrial microscope.

[0016] The beneficial effects of this invention are: This equipment adopts a detection structure with an internal expansion of the first air bladder, replacing the traditional detection method of directly filling the corrugated pipe with compressed air. During the detection process, the high-pressure gas is always inside the first air bladder. Even if the corrugated pipe has material defects, uneven wall thickness, hidden cracks and is damaged, there will be no situation where high-pressure gas leaks out and forms a high-speed jet airflow, which can effectively ensure the personal safety of on-site operators.

[0017] Light emitted from the cylindrical lamp shines outward through the highly transparent first airbag. When the corrugated pipe has through-hole defects such as cracks or pinholes, the light can be transmitted through the defect location and accurately captured by the industrial microscope. At the same time, by utilizing the corrugated pipe's own light-shielding properties, hidden forming defects such as uneven wall thickness and local thinning can be identified based on the differences in light transmittance at various locations. Combined with the servo motor driving the corrugated pipe to rotate throughout its entire range, a blind-angle scanning is achieved, greatly improving the accuracy and comprehensiveness of defect detection.

[0018] Before the first airbag is inflated for testing, the electric push rod drives the right-side clamp, sliding rod and cylindrical light to move to the right, stretching the bellows and the first airbag. The spring is stretched synchronously, straightening the corrugated bellows into a regular cylindrical shape. The subsequent inflation of the first airbag allows all the folds of the bellows to fully unfold, avoiding the folds from overlapping and obscuring defects, thereby eliminating blind spots in the inspection.

[0025] The first airbag 105 is made of highly transparent silicone material.

[0026] The second airbag 202 is made of fluororubber and has a rough surface to increase the friction between it and the bellows 5.

[0027] The length of the cylindrical lamp 108 is greater than the length of the corrugated pipe 5 under maximum tension.

[0028] The corrugated pipe 5 used in vehicles is usually black, and this invention is particularly suitable for light transmission detection of black corrugated pipes.

[0029] The working principle of Example 1 is as follows: In the initial state, the electric push rod 103 is in the retracted state. At this time, the right clamping block 104 is separated from the sliding rod 107, leaving sufficient space for loading. During the loading process, the worker first places the corrugated pipe 5 on the outside of the first airbag 105 and inserts the left end of the corrugated pipe 5 into the clamping groove 10405 on the left clamping block 104. Then, the electric push rod 103 is controlled to push the connector 106 and the right clamping block 104 to the left, so that the conductive plug 10601 is inserted into the conductive slot 10702. When the electromagnet 204 comes into contact with the clamping block 104 on the right, the worker inserts the right end of the corrugated pipe 5 into the clamping groove 10405 on the right clamping block 104. Then, the power supply of the equipment is turned on, the electromagnet 204 is turned on, so that the sliding rod 107 is magnetically fixed to the clamping block 104 on the right. The second connecting pipe 20301 is inflated by an external air pump, and then the airflow will enter the corresponding second airbag 202 through the second cavity 10403, so that the second airbag 202 expands to clamp and fix the end of the corrugated pipe 5 in the clamping groove 10405.

[0030] After the bellows 5 is fixed, the external air pump is started to inflate the first connecting pipe 20101. The airflow enters the first airbag 105 through the first cavity 10401 and the air inlet slot 10402, causing the silicone first airbag 105 to expand and fit more evenly against the inner side of the bellows 5. Then, as the first airbag 105 continues to expand, it expands the bellows 5. The internal air pressure of the second airbag 202 is set to be greater than the internal air pressure of the first airbag 105, so that the clamping force of the second airbag 202 on the bellows 5 is greater than that of the first airbag 105. The first airbag 105 provides internal support to the bellows 5, effectively preventing it from loosening. After the bellows 5 is expanded, the servo motor 101 drives the connecting rod 102 and the left clamping block 104 to rotate, which in turn drives the sliding rod 107, the bellows 5, and the right clamping block 104 to rotate synchronously. At this time, the right clamping block 104 rotates relative to the connector 106 through the connecting end 10404. Then, the industrial microscope 3 takes real-time images of the surface of the bellows 5 during its rotation. The system displays the magnified image on the screen 4 in real time, facilitating workers' inspection of the corrugated pipe 5 for visual defects. After inspection, an external air pump is used to evacuate the first connecting pipe 20101, expelling the gas from the first airbag 105 and releasing the internal support of the first airbag 105 on the corrugated pipe 5, allowing the corrugated pipe 5 to return to its original shape. Then, an industrial microscope 3 is used to compare the images of the corrugated pipe 5 before and after expansion to check the retraction and recovery effect of the corrugated pipe 5. This equipment expands the corrugated pipe 5 by inflating the first airbag 105, which has an intact and defect-free surface. This solves the problem in the existing technology where compressed air is directly injected into the corrugated pipe 5. If the corrugated pipe 5 itself has material defects, uneven wall thickness, or hidden cracks, it is very easy to break under pressure. At the moment of rupture, the high-pressure gas inside the corrugated pipe 5 is released rapidly, forming a high-speed jet of air. This not only easily causes impact injuries to on-site personnel, but the rubber fragments generated by the rupture will also fly with the airflow, further aggravating the safety risks.

[0031] This device relies on the first rotating ring 201 and the second rotating ring 203 to achieve independent airflow along the rotating structure, effectively avoiding the problem of air pipe entanglement. The first rotating ring 201 is rotatably mounted on the left clamping block 104, and the two together form the first cavity 10401. The first connecting pipe 20101 is externally connected to an air pump and fixed to the first rotating ring 201. When the device is running, the first rotating ring 201 remains stationary, and the left clamping block 104 rotates circumferentially with the servo motor 101. The first cavity 10401 is always connected to the first connecting pipe 20101 and the air inlet slot 10402, continuously and stably supplying and evacuating air to the first airbag 105. Each clamping block 104 is rotatably mounted with a second rotating ring 203, forming a second cavity 10403 between the second rotating ring 203 and the corresponding clamping block 104. The second connecting pipe 20301 is fixed to the second rotating ring 203 and connected to an external air passage. During operation, the second rotating ring 203 remains stationary, while the clamping block 104 rotates independently. The second cavity 10403 continuously conducts air passage to supply air pressure to the second airbag 202. The above-mentioned rotating air passage structure with separation of dynamic and static components ensures that the external air pipe will not twist and entangle with the rotating components during the full rotation detection of the clamping block 104 and the bellows 5, and that the air passage delivery is continuous and the operation is stable.

[0032] Furthermore, after the bellows 5 is expanded by the first airbag 105, power is supplied to the cylindrical lamp 108 through an external power source. When the cylindrical lamp 108 is turned on, it will emit light from inside the first airbag 105. Even if there are small cracks or holes on the surface of the bellows 5, the light source can still shine through these cracks and holes. The industrial microscope 3 can capture these small defects in time. When there are local weak areas or abnormal light transmission areas in the bellows 5, the difference in light transmission can also be collected by the industrial microscope 3 to detect the problem of uneven wall thickness of the bellows 5, which greatly improves the detection effect of the equipment. In addition, by filling the first airbag 105 with cold air, the first airbag 105 is expanded and the heat generated by the cylindrical lamp 108 during operation is carried away by the cold air. This avoids the problem of the cylindrical lamp 108 located inside the first airbag 105 accumulating a lot of heat after long-term operation, and the heat is difficult to dissipate, which affects the service life of the cylindrical lamp 108 and the first airbag 105.

[0033] Furthermore, before inflating the first connecting tube 20101, the electric push rod 103 is activated to move the right clamping block 104 to the right. At this time, the sliding rod 107 is magnetically fixed to the right clamping block 104 through the electromagnet 204, thereby moving the right clamping block 104, the sliding rod 107, and the cylindrical lamp 108 to the right. At this time, the spring 109 is stretched by force, pulling the bellows 5 and the first airbag 105 apart, so that the surface of the bellows 5 is in a regular cylindrical shape. Then, the first airbag 105 is inflated to expand the bellows 5, so that the folds of the bellows 5 are fully unfolded, avoiding the folds of the bellows 5 from overlapping and blocking the area below when unfolded, which would affect the detection of the folded area. Moreover, the length of the cylindrical lamp 108 is greater than the length of the bellows 5 in the maximum stretched state, so it can completely cover the internal area of ​​the bellows 5, avoiding local light loss, which would interfere with subsequent detection.

[0034] The cylindrical lamp 108 is covered with an explosion-proof transparent cover. When the first airbag 105 is inflated, it will compress the cylindrical lamp 108 inside. The explosion-proof transparent cover can buffer the compression effect of the air pressure and prevent the cylindrical lamp 108 from being damaged by pressure.

[0035] It also includes contact rings 10704; three contact rings 10704 are fixedly connected inside the conductive slot 10702. The contact rings 10704 are made of copper; each contact ring 10704 is in close contact with the conductive plug 10601; the copper contact rings 10704 have good conductivity, and multiple sets of contact points can improve the stability of circuit connection and avoid problems such as power failure and poor contact during equipment operation.

[0036] Example 2: Based on Example 1, such as Figure 1 and Figure 7 As shown, it also includes a supplementary light 205; the supplementary light 205 is fixedly attached to the lower side of the industrial microscope 3.

[0037] It also includes a light shield 206; the industrial microscope 3 has a light shield 206 fixed to its lower side.

[0038] Working principle of Example 2: When the wall thickness of the corrugated pipe 5 is detected by illuminating the light source from the inside out through the cylindrical lamp 108, the light shield 206 can block external stray light to prevent external light from interfering with the light transmission detection and ensure the accuracy of the wall thickness detection. When performing routine appearance inspection on the corrugated pipe 5, the supplementary light lamp 205 can provide a uniform auxiliary light source to the inspection area, optimize the surface lighting environment of the corrugated pipe 5, improve the imaging quality of the industrial microscope 3, and help the equipment accurately identify various minor appearance defects.
