Description

Technical Field

[0001] This invention relates to the field of external hose testing technology, and in particular to a testing device for high wear-resistant and compression-resistant hydraulic hoses. Background Technology

[0002] With the continuous advancement of new material research and development, a series of high-performance new materials have been applied to the manufacturing of hydraulic hoses. The outer hose of a hydraulic hose is directly exposed to a complex working environment and needs to withstand high pressure, frequent extrusion, and various harsh conditions. Therefore, the wear resistance and extrusion resistance of the outer hose material have become important indicators for measuring the quality of hydraulic hoses.

[0003] Existing external hose testing devices typically apply pressure and record data at several specific points on the surface of the external hose, which is not convenient for comprehensive testing of the external hose. This reduces the comprehensiveness of the compression resistance test data. Furthermore, compression resistance testing and abrasion resistance testing are usually performed separately when testing external hoses. This step-by-step testing mode not only makes the testing process cumbersome and time-consuming, but also makes it difficult to comprehensively consider the potential correlation between the two key performance indicators.

[0015] Beneficial effects 1. This invention, through the ingenious combination of a proximity sensor and a metal block, enables the control module to accurately sense the proximity of the metal block to the proximity sensor and precisely control the drive motor to reverse. This innovative design allows the detection structure to drive the extrusion roller to move stably and regularly back and forth on the outside of the hose body, ensuring that every part of the hose body is subjected to uniform extrusion, thereby achieving comprehensive extrusion detection of the hose body. This effectively avoids the detection blind spots that may occur in traditional detection methods, greatly improving the accuracy and reliability of the detection results. At the same time, during the extrusion process of the extrusion roller on the hose body, the friction between the extrusion roller and the extrusion seat is cleverly utilized, realizing simultaneous wear resistance detection of the hose body by the extrusion roller while performing extrusion resistance detection. This dual detection mode not only saves detection time and cost but also avoids the accumulation of errors that may be caused by step-by-step detection, making the detection results more accurately reflect the comprehensive performance of the hose body. In addition, the counting module can accurately record the number of times the extrusion roller extrudes the hose body, providing important data support for evaluating the fatigue resistance performance of the hose body.

[0016] 2. This invention, by providing a sliding column and a linkage seat, as well as a linkage plate and a connecting seat, enables one set of extrusion seats to move in the opposite direction when one set of extrusion seats moves; thus, it enables the two sets of extrusion rollers to simultaneously extrude the top and bottom of the hose body; ensuring that the hose body is subjected to uniform force during the extrusion process; at the same time, when the electric cylinder drives the pressure seat to extrude the hose body through the pressure seat and the vertical rod, the rubber column will simultaneously extrude the pressure sensor; thus, the pressure value of the pressure sensor can indicate the extrusion force of the extrusion rollers on the hose body.

[0017] 3. This invention, by providing a double-headed screw A and two sets of adjusting brackets, enables the two sets of fixing mechanisms to move in opposite directions simultaneously, which is beneficial for fixing the hose body according to its specific length. Simultaneously, as the adjusting brackets move, the proximity sensor also moves accordingly. This allows for control of the reciprocating movement path of the detection structure based on the specific length of the hose body. Furthermore, by adjusting the screw, auxiliary seat, and guide bracket, the distance between the limiting seat and the auxiliary seat can be adjusted, thereby controlling the distance between the endpoint of the detection bracket's movement path and the clamping plate. This helps prevent collisions between the extrusion assembly and the clamping plate.

[0018] 4. In this invention, the linear array camera in the detection structure is located on the same horizontal plane as the main body of the rubber tube, which can capture images of the surface of the rubber tube in real time during the detection process and transmit the image information to the information acquisition module. Through image analysis technology, defects such as wear and scratches on the surface of the rubber tube can be detected in a timely manner, realizing real-time monitoring of extrusion resistance and wear resistance. This non-contact detection method not only avoids secondary damage to the rubber tube, but also improves detection efficiency and accuracy, providing strong support for timely detection of quality problems.

[0019] 5. The present invention, by providing an air outlet groove, enables the gas inside the hose body to be smoothly discharged through the air outlet groove when the extrusion roller extrudes the hose body. This design effectively avoids the residual gas inside the hose body from generating additional pressure or interference during the extrusion process, thereby preventing it from adversely affecting the extrusion test results and ensuring the accuracy and reliability of the test results.

[0037] The specific usage and function of this embodiment are as follows: In this invention, when in use, according to the length of the hose body 3 to be tested, rotate the handwheel at the top of the double-ended screw A103 inside the fixing frame 101, so that the adjusting frame 102 slides through the dovetail groove, thereby adjusting the distance between the two sets of fixing mechanisms 2 to be slightly larger than the length of the hose body 3; put both ends of the hose body 3 onto the inner support column 202, and then rotate the double-ended screw B204.

When the pressure value reaches the detection requirement, electric cylinder 602 stops working; then drive motor 406 is started. Drive motor 406 drives two sets of drive screws 402 to rotate synchronously through sprocket 403 and chain 404, causing drive seat 405 to move the detection structure 6 as a whole; when the detection frame 601 moves and the metal block 609 approaches proximity sensor 504, proximity sensor 504 transmits a signal to control module 604.

As the extrusion roller 706 rotates, the friction between the extrusion roller 706 and the extrusion seat 705 causes wear on the surface of the hose body 3, thus achieving wear resistance testing. The line scan camera 608 is located on the same horizontal plane as the hose body 3, capturing images of the hose surface in real time during the inspection process and transmitting the image information to the information acquisition module 603. Through image analysis technology, defects such as wear and scratches on the hose surface can be detected in a timely manner.The operator records data such as the pressure value, number of compressions, and surface defect information of the hose detected by the line scan camera 608, as displayed on the monitor 606; this data is then analyzed in depth to assess whether the extrusion resistance and abrasion resistance of the hose body 3 meet relevant standards and requirements.
