Description

Technical Field

[0001] This invention relates to the field of automotive hose testing equipment, and more specifically, to a hose testing device for automotive hose extruders. Background Technology

[0002] In modern automotive manufacturing, automotive hoses, as a core component of the piping system, play a decisive role in the overall vehicle performance due to their dimensional accuracy. Precise dimensions effectively ensure the vehicle's sealing performance, preventing liquid or gas leaks, while significantly improving the hoses' aging resistance and extending their service life, thereby ensuring the overall safety of the vehicle.

[0003] Laser diameter gauges, with their significant advantages such as non-contact measurement, high-precision detection, and real-time feedback, have become a key testing device in the quality control process of automotive hose production. Their working principle involves a laser emitting a beam, which, after being processed by a multi-faceted scanning mirror and scanning optical system, forms a continuous high-speed scanning beam parallel to the optical axis, rapidly scanning the workpiece within the measurement area. A photodetector located on the other side of the workpiece receives the scanning beam. When the beam scans the workpiece, it is blocked. By analyzing the output signal of the photodetector, data related to the workpiece diameter can be obtained.

[0004] Taking the laser diameter measuring instrument disclosed in patent document CN204177352U as an example, the device includes a display screen with a control panel, a hexagonal frame connected to the control panel, and a notch at the port of the frame. A first laser and a second laser emitter are arranged in a cross shape on the inner wall of the square frame. The first laser includes a first laser emitter and a first laser receiver located on the same straight line, and the second laser includes a second laser emitter and a second laser receiver located on the same straight line. A guide wheel structure is also provided at the bottom of the frame, consisting of two parallel guide wheels mounted on the inner wall of the frame via an adjuster. Although this utility model achieves automatic detection of pipes, in practical applications, it has been found that even slight vibrations when the pipe moves on the guide wheels can significantly increase the measurement error, severely affecting the accuracy of the detection results and making it difficult to meet the increasingly stringent high-precision detection requirements in automotive hose production.

Detailed Implementation

[0030] To further understand the content of this invention, a detailed description of the invention will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative and not limiting of the invention.

[0031] Example 1, as Figure 1-2 As shown, this embodiment provides a hose inspection device for automotive hose extruders, which includes a laser diameter gauge 100. The laser diameter gauge 100 includes two sets of laser emitters 210 and photoelectric receivers 220, and also includes two sets of clamping mechanisms disposed at both ends of the two sets of laser emitters 210 and photoelectric receivers 220. The clamping mechanism includes a circular mounting plate 130, combined with... Figure 4 as well as Figure 8 As shown, a fixing plate 810 is provided at the laser diameter measuring instrument 100, and a connecting plate 4100 is provided at the mounting plate 130 to be bolted to the fixing plate 810.

[0032] The mounting plate 130 has a through hole 131 at its center for the automotive hose to pass through. The mounting plate 130 has at least three grooves 140; in this embodiment, there are four grooves 140. The at least three grooves 140 communicate with the through hole 131 and are evenly distributed circumferentially along the through hole 131. A slider 150 slides within the groove 140, with its end extending into the through hole 131. A guide wheel 160 is rotatably mounted on the end of the slider 150 extending into the through hole 131. The mounting plate 130 has an adjustment mechanism for adjusting the position of the slider 150 so that the guide wheel 160 clamps the automotive hose.

[0033] When the car hose enters the detection device, it first passes through the through hole 131 of the mounting plate. The adjustment mechanism is then activated, and four sets of guide wheels form a symmetrical clamping force, stably fixing the hose at the center of the through hole 131 to prevent radial movement. The two sets of laser emitters 210 of the laser diameter gauge 100 emit beams, which are then received by the photoelectric receiver 220 after being blocked by the hose. The hose diameter data is obtained by calculating the time difference between the beam blocking and the actual diameter.

[0034] In this embodiment, the passively supported guide wheel in the prior art is improved into an active adaptive clamping mechanism, which better solves the measurement error problem caused by hose vibration, thereby improving the accuracy of automotive hose diameter measurement and meeting the high-precision and high-efficiency testing requirements of automotive hose production lines.

[0035] Meanwhile, in this embodiment, the adjustment mechanism can control the clamping range of the guide wheel 160 by adjusting the position of the slider 150, thereby accommodating the inspection of automotive hoses of different diameters. Compared with the traditional fixed guide wheel structure, it can adapt to the production needs of multiple specifications without changing the hardware, thus significantly improving the inspection efficiency of automotive hoses.

[0036] Combination Figure 5 As shown, in order to realize the rotation of the guide wheel 160, the end of the slider 150 that extends into the through hole 131 of the mounting plate is provided with a set of roller shaft mounting seats 510, the guide wheel 160 is disposed between the set of roller shaft mounting seats 510, and an optical axis 520 passing through the guide wheel 160 is provided between the set of roller shaft mounting seats 510.

[0037] By rotatably connecting the guide wheel 160 to the roller mounting base 510 via the optical shaft 520, the guide wheel 160 rotates synchronously when the hose moves, reducing frictional resistance and maintaining stable clamping force, thus avoiding positional displacement caused by hose movement and improving the stability of the hose detection device for automotive hose extruders during use.

[0038] Combination Figure 3 as well as Figure 4As shown, a rotating seat mounting cavity 410 is provided at the mounting plate 130, and the adjustment mechanism includes a rotating seat 420 rotatably disposed in the rotating seat mounting cavity 410, combined with... Figure 7 As shown, in order to realize the rotation of the rotating seat 420, a screw hole 710 is provided at the bottom end face of the rotating seat mounting cavity 410, and a countersunk hole 720 is provided at the rotating seat 420. A semi-threaded bolt 730 that mates with the screw hole 710 is provided in the countersunk hole 720.

[0039] In this embodiment, by setting the semi-threaded bolt 730 and the countersunk hole 720, the rotating seat 420 can be installed in the rotating seat mounting cavity 410 through the cooperation between the semi-threaded bolt 730 and the screw hole 710. In this embodiment, the diameter of the countersunk hole 720 is larger than the diameter of the semi-threaded bolt 730, so that the rotating seat 420 can rotate in the rotating seat mounting cavity 410.

[0040] The adjustment mechanism also includes a clamping member disposed at the slider 150. The clamping member includes two rotatably disposed clamping posts 530. An eccentric plate 430 capable of rotating synchronously with the rotating seat 420 is provided at the rotating seat 420. In this embodiment, the eccentric plate 430 is bolted to the rotating seat 420. Figure 6 As shown, the eccentric plate 430 includes a circular portion 610 and a protruding portion 620. The edge of the eccentric plate 430 is provided with a surrounding plate 630 that extends between the two rotatably configured clamping columns 530. The mounting plate 130 is provided with a rotating seat drive mechanism that drives the rotating seat 420 to rotate in order to adjust the position of the slider 150.

[0041] The eccentric plate 430 consists of a circular portion 610 and a protruding portion 620, with a difference in the offset between their centers. When the rotating seat 420 drives the eccentric plate to rotate, the radial distance of the protruding portion 620 is greater than that of the circular portion 610, thereby pushing the clamping column 530 to drive the slider 150 to slide in the groove 140.

[0042] In this embodiment, the adjustment mechanism, through the design of the eccentricity, converts the angular displacement of the rotating seat 420 into the linear displacement of the slider 150, thereby realizing the adjustment of the position of the guide wheel 160. This allows the guide wheel 160 to better clamp automotive hoses of different diameters, thus improving the applicability of the hose detection device for automotive hose extruders.

[0043] The protrusion 620 and the circular part 610 adopt an arc transition design, which can reduce the frictional wear between the enclosure 630 and the clamping column 530 and avoid jamming.

[0044] Combination Figure 4As shown, the rotating base 420 has a toothed block 440 arranged circumferentially on its side wall. The rotating base driving mechanism includes an annular plate 450 rotatably sleeved around the mounting plate 130. In this embodiment, to achieve the installation of the annular plate 450, a mounting plate protrusion 470 arranged circumferentially is provided on the outer side wall of the mounting plate 130, and an annular groove 480 with clearance fit to the mounting plate protrusion 470 is provided on the inner wall of the annular plate 450. An internal gear ring 460 meshing with the toothed block 440 is provided on the inner wall of the annular plate 450; the laser diameter measuring instrument 100 is provided with an annular plate driving mechanism for driving the annular plate 450 to rotate.

[0045] In this embodiment, the annular plate 450 simultaneously engages with the toothed block 440 of the rotating seat 420 at the mounting plate 130, thereby achieving synchronous adjustment of the rotating seat 420 at the mounting plate 130. This avoids different displacements of the slider 150 at different locations on the mounting plate 130, ensuring uniform clamping force at both ends of the hose and preventing hose bending due to excessive force on one side, thus significantly improving the stability of the hose detection device for automotive hose extruders during use.

[0046] Furthermore, the laser diameter measuring instrument 100 is provided with a set of mounting brackets 310, and the annular plate driving mechanism includes a rotating rod 320 rotatably disposed between the set of mounting brackets 310. The outer wall of the annular plate 450 is provided with an annular plate external gear ring 490. The rotating rod 320 is provided with a driven gear 330 that meshes with the annular plate external gear ring 490 of the two clamping mechanisms. The set of mounting brackets 310 is also provided with a drive motor 340, and the shaft of the drive motor 340 is provided with a driving gear 350 that meshes with the driven gear 330.

[0047] In use, the drive motor 340 meshes with the driven gear 330 through the drive gear 350, driving the rotating rod 320 to rotate. The driven gears 330 at both ends of the rotating rod 320 mesh with the outer gear rings 490 of the two annular plates, realizing the synchronous drive of the two clamping mechanisms.

[0048] In this embodiment, the annular plate driving mechanism drives the annular plates 450 at the two clamping mechanisms through the same rotating rod 320, so that the displacement of the sliders 150 at different mounting plates 130 is the same, ensuring that the force at both ends of the hose is uniform, thereby avoiding bending of the hose due to the different displacement of the sliders 150 at the two clamping mechanisms, thus improving the stability of the hose detection device for automotive hose extruders during use.

[0049] The specific working principle of the hose testing device for automotive hose extruders in this embodiment is as follows:

[0050] First, the automotive hose enters from one end of the device and passes through the mounting plate through hole 131 in the center of the mounting plate 130. The mounting plate 130 is circular, and its outer side wall is provided with mounting plate protrusions 470 distributed circumferentially, which are used to form a clearance fit with the annular groove 480 of the annular plate 450 to realize the circumferential rotation guidance of the annular plate 450.

[0051] The drive motor 340 starts, and the driving gear 350 on its shaft meshes with the driven gear 330, driving the rotating rod 320 to rotate between the mounting brackets 310. The mounting brackets 310 are fixed to the laser diameter gauge 100, providing rigid support for the rotating rod 320. The driven gears 330 at both ends of the rotating rod 320 mesh with the outer gear rings 490 of the annular plates 450 on both sides, driving the annular plates 450 to rotate around the periphery of the mounting plate 130. The inner gear ring 460 on the inner wall of the annular plate 450 meshes synchronously with the toothed blocks 440 on the side wall of the rotating seat 420, causing the rotating seat 420 to rotate within the rotating seat mounting cavity 410.

[0052] The rotating seat 420 is connected to the screw hole 710 on the bottom surface of the rotating seat mounting cavity 410 by a half-threaded bolt 730, and the eccentric plate 430 on its top rotates synchronously with the rotating seat 420. The eccentric plate 430 consists of a circular part 610 and a protruding part 620, and the edge plate 630 extends into the clamping post 530 of the slider 150.

[0053] When the eccentric plate 430 rotates, the protrusion 620 pushes the clamping column 530, causing the slider 150 to slide towards the center of the through hole 131 in the mounting plate 130 through the groove 140. There are four grooves 140, which are evenly distributed around the circumference of the through hole in the mounting plate.

[0054] Guide wheels 160 are mounted on the end of slider 150 via roller mounting base 510 and optical axis 520. As slider moves, four sets of guide wheels 160 synchronously adhere to the outer wall of the hose, forming an annular clamp. Guide wheels 160 can rotate around optical axis 520, reducing frictional resistance when hose moves.

[0055] The laser diameter gauge 100 emits laser beams from two sets of laser emitters 210. After being blocked by the rubber tube, the beams are received by the photoelectric receiver 220. The diameter of the rubber tube is obtained by calculating the time difference of the beam blocking. The laser diameter gauge 100 is bolted to the connecting plate 4100 of the mounting plate 130 via the fixing plate 810 to ensure installation accuracy.

[0056] When the diameter of the hose fluctuates, the drive motor 340 rotates, and through the transmission chain of the drive gear 350-driven gear 330-rotating rod 320-ring plate outer gear ring 490, the rotation angle of the ring plate 450 is adjusted in real time, which drives the rotating seat 420 and the eccentric plate 430 to rotate synchronously, dynamically adjusting the position of the slider 150 and maintaining the clamping force of the guide wheel 160 on the hose.

[0057] In summary, the above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made within the scope of the claims of the present invention should be covered by the present invention.
