Description

Technical Field

[0001] The invention relates to the technical field of external rubber hose detection, in particular to a highly wear-resistant and extrusion-resistant external rubber hose detection device for hydraulic oil pipes. Background Art

[0002] With the continuous advancement of new material research and development, a series of high-performance new materials have been used in the manufacture of hydraulic oil pipe outer hoses; hydraulic oil pipe outer hoses are directly exposed to complex working environments and need 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 oil pipes.

[0003] Existing external hose testing devices usually select several specific points on the surface of the external hose to apply pressure and record data when testing the external hose, which is not convenient for comprehensive testing of the external hose and reduces the comprehensiveness of the anti-extrusion test data. In addition, when testing external hoses, anti-extrusion testing and wear resistance testing are usually performed separately.

[0015] Beneficial effects 1. In the present invention, through the ingenious combination of the proximity sensor and the metal block, the control module can accurately sense the proximity of the metal block to the proximity sensor and accurately control the reverse rotation of the drive motor accordingly. This innovative design enables the detection structure to drive the squeezing roller to perform stable and regular reciprocating movement on the outside of the hose body, ensuring that every part of the hose body is evenly squeezed, thereby achieving comprehensive squeezing detection of the hose body, effectively avoiding the detection blind spots that may occur in traditional detection methods, and greatly improving the accuracy and reliability of the detection results. At the same time, during the squeezing process of the squeezing roller on the hose body, the friction between the squeezing roller and the squeezing seat is cleverly utilized to achieve simultaneous wear resistance testing of the hose body during anti-extrusion testing. This dual detection mode not only saves detection time and cost, but also avoids the error accumulation that may result from step-by-step detection, so that the test results more accurately reflect the comprehensive performance of the hose body. At the same time, the counting module can accurately record the number of times the squeezing roller squeezes the hose body, providing important data support for evaluating the fatigue resistance of the hose body.

[0016] 2. The present invention, by providing a sliding column and a linkage seat as well as a linkage plate and a connecting seat, can enable one group of extrusion seats to move in the opposite direction when one group of extrusion seats moves; thereby, the top and bottom of the hose body can be extruded synchronously by two groups of extrusion rollers, 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 squeeze the pressure sensor; thereby, the pressure value of the pressure sensor can indicate the extrusion force of the extrusion roller on the hose body.

[0017] 3. The present invention, by providing a double-headed screw A and two sets of adjustment frames, can make the two sets of fixing mechanisms move in opposite directions at the same time, which is beneficial to fixing the hose body according to the specific length of the hose body; at the same time, when the adjustment frame moves, the proximity sensor will also move accordingly; thus, the reciprocating movement distance of the detection structure can be controlled according to the specific length of the hose body; and by adjusting the screw, the auxiliary seat and the guide frame, the distance between the limit seat and the auxiliary seat can be adjusted; thus, the distance between the end point of the movement path of the detection frame and the splint can be controlled, which is beneficial to prevent the extrusion component from colliding with the splint.

[0018] 4. In the present invention, the linear array camera in the detection structure is located on the same horizontal plane as the hose body. It can capture images of the hose surface 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 hose surface can be promptly discovered, and real-time monitoring of the anti-extrusion performance and wear resistance can be achieved. This non-contact detection method not only does not cause secondary damage to the hose, but also improves detection efficiency and accuracy, providing strong support for the timely discovery of quality problems.

[0019] 5. The present invention is provided with an air outlet groove, which enables the gas in the hose body to be smoothly discharged through the air outlet groove when the extrusion roller squeezes the hose body. This design effectively avoids the residual gas in the hose body from generating additional pressure or interference during the extrusion process, thereby preventing it from causing adverse effects on the extrusion test results and ensuring the accuracy and reliability of the test results.

[0037] Specific usage and function of this embodiment: In the present invention, when in use, according to the length of the hose body 3 to be tested, the handwheel at the top of the double-headed screw A103 inside the fixing frame 101 is rotated to make the adjusting frame 102 slide through the dovetail groove, so that the spacing between the two sets of fixing mechanisms 2 is adjusted to be slightly larger than the length of the hose body 3; the two ends of the hose body 3 are put on the inner support column 202, and then the double-headed screw B204 is rotated, and the double-headed screw B204 drives the two sets of clamping seats 205 to move in the opposite direction, so that the two sets of clamping plates 208 move inward, and the two ends of the hose body 3 are firmly clamped between the inner support column 202 and the clamping plate 208; then the spacing between the two sets of fixing mechanisms 2 is adjusted to make the hose body 3 in a taut state; then the adjusting The screw 505 and the adjusting screw 505 drive the limit seat 503 to move horizontally through the guide frame 502 and the auxiliary seat 501, so that the proximity sensor 504 reaches the appropriate position; then the electric cylinder 602 is started, and the electric cylinder 602 drives the pressure seat 707 to move downward, and the pressure seat 707 drives a group of extrusion seats 705 to move downward through the vertical rod 708. The extrusion seats 705 drive another group of extrusion seats 705 to move in the opposite direction through the linkage seat 702 and the linkage plate 703 and the guide column 701 and the connecting seat 704, so that the two groups of extrusion rollers 706 squeeze the hose body 3, so that the gas in the hose body 3 is discharged through the air outlet groove 203; at the same time, the rubber column 7010 squeezes the pressure sensor 7011, which can be used to The pressure value of the pressure sensor 7011 indicates the squeezing force of the squeezing roller 706 on the hose body 3; the pressure value of the pressure sensor 7011 can be observed by the display 606. When the pressure value reaches the detection requirement, the electric cylinder 602 stops working; then the drive motor 406 is started, and the drive motor 406 drives the two sets of drive screws 402 to rotate synchronously through the sprocket 403 and the chain 404, so that the drive seat 405 drives the detection structure 6 to move as a whole; when the detection frame 601 moves so that the metal block 609 approaches the proximity sensor 504, the proximity sensor 504 transmits a signal to the control module 604, and the control module 604 immediately controls the drive motor 406 to reverse, so that the detection structure 6 moves in the opposite direction, realizing the detection structure 6 reciprocates on the outside of the hose body 3 to ensure comprehensive and uniform inspection of the hose body 3; at the same time, the control module 604 controls the counting module 605 to synchronously record the number of times the squeezing roller 706 squeezes the hose body 3, providing data support for evaluating the fatigue resistance of the hose body 3; since when the squeezing roller 706 rotates, the friction between the squeezing roller 706 and the squeezing seat 705 will cause wear on the surface of the hose body 3, thereby realizing wear resistance inspection; the line array camera 608 is located at the same horizontal plane as the hose body 3, and takes real-time images of the hose surface during the inspection process, and transmits 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 discovered in a timely manner;The operator records the pressure value and number of squeezes displayed on the display 606, as well as the hose surface defect information detected by the line array camera 608.
