Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art.

[0045] See Figure 1-13The present invention discloses a testing device for an automated hydraulic accelerator, comprising an electro-hydraulic control platform 3 and a hydraulic conversion platform 4, and a base plate 1. A first test support rod 15 and a second test support rod 105 are provided on the upper end face of the base plate 1. A drive assembly is provided between the first test support rod 15 and the second test support rod 105. A testing assembly 6 includes a test hydraulic cylinder 64 and a movable base 19. The test hydraulic cylinder 64 is disposed on the upper end face of the base plate 1, and the movable base 19 is disposed on the upper end face of the base plate 1 and located at one end of the first test support rod 15. A hydraulic cylinder test head 604 is provided between the movable base 19 and the test hydraulic cylinder 64. A protection assembly 2 is disposed on the upper side of the first test support rod 15 and the second test support rod 105. In use, the hydraulic accelerator 901 to be tested is placed on one end of the first test support rod 15 and the second test support rod 105 on the base plate 1. To ensure the stability of the hydraulic accelerator 901, a placement notch 101 is provided on the end face of both the first test support rod 15 and the second test support rod 105. During testing, the hydraulic accelerator 901 to be tested is driven to the other end of the first test support rod 15 and the second test support rod 105 by the set drive component. The movable end 902 of the hydraulic accelerator 901 to be tested is used to connect with the movable base 19. Then, the hydraulic cylinder test head 604 of the test component 6 drives the movable base 19 to stretch the movable end 902 of the hydraulic accelerator 901 to be tested, forming a stretching stroke 903. At the same time, a protective component 2 is set on the upper side of this area. By covering the entire test area with the protective component 2, the hydraulic accelerator 901 to be tested is prevented from breaking and causing accidental damage. Simultaneously, a strip lamp 9, a working camera 90, and a displacement sensor 91 can be further installed on the inner side wall of the protective component. This facilitates observation of the inner test status via the working camera 90 through the electro-hydraulic control platform 3. Furthermore, the electro-hydraulic control platform 3 controls the working status of the drive component; the light switch of the strip lamp 9; the camera switch of the working camera 90; and the displacement sensor switch of the displacement sensor 91. The electro-hydraulic control platform 3 displays the test status, processes data, performs calculations, and generates statistical tables.

[0046] The electro-hydraulic control platform 3 is used to collect the stroke of the hydraulic accelerator under test from the displacement sensor 91, collect the tension and force values ​​of the hydraulic accelerator under test from the extension and retraction of the test hydraulic cylinder 64, and collect the number of tension and force tests of the hydraulic accelerator under test by collecting the number of cycles of the full extension and release stroke of the test hydraulic cylinder 64.

[0047] For the electro-hydraulic control platform 3, data acquisition is achieved. The displacement sensor 91 serves as the data acquisition source, collecting signals. These signals are amplified, filtered, and linearized using common signal conditioning circuits, converting them into analog signals for the data acquisition card. The data acquisition card then converts the analog signals into digital signals for processing by the computer software on the electro-hydraulic control platform 3, before displaying the displacement of the tested tool on the monitor. The bar light is manually controlled, and the working camera 90 is locally controlled. Using the camera's accompanying software on the computer, the tested image of the hydraulic accelerator's motion status can be displayed on the monitor.

[0048] Furthermore, the electro-hydraulic control platform 3 is interconnected with the hydraulic conversion platform 4. The electro-hydraulic control platform 3 controls the passage state of the hydraulic conversion platform 4, thereby enabling it to control the working state of the test components and the adjustment components.

[0049] participate Figures 8-9 Specifically, the driving assembly includes a first positioning plate 14, which is disposed on the upper end face of the base plate 1; a second positioning plate 17, which is disposed on the upper end face of the base plate 1, located on the opposite side of the first positioning plate 14 and below the protection assembly 2, and the first positioning plate 14 and the second positioning plate 17 are provided with multiple sets of lead screws 106; a first slide rail 16, which consists of at least two sets and is disposed between the first positioning plate 14 and the second positioning plate 17; and a sliding base 160, which is slidably connected to the upper side of the first slide rail 16 and rotatably connected to the lead screws 106.

[0050] The drive assembly also includes a drive motor 18, which is disposed on one side of the second positioning plate 17 and meshes with one end of the lead screw 106 via gears to achieve power transmission. In use, by providing power to the drive motor, power is transmitted through gear meshing between the motor and the lead screw 106 as the motor rotates forward and backward. The rotation of the lead screw 106 causes the sliding base 160 to move along the first slide rail 16, and the sliding base 160, with its upper end face forming an outward-facing limiting groove 1600, holds the hydraulic accelerator 901 to be tested, thereby moving the hydraulic accelerator 901 to the test assembly for tensile testing.

[0051] participate Figure 9In this design, multiple sets of second slide rails 190 are provided between the movable base 19 and the base plate 1, and the movable base 19 is slidably connected to the second slide rails 190. In use, the extension and retraction of the hydraulic cylinder test head 604 drives the movable base 19 to move along the second slide rails 190, which also drives the stretching of the movable end 902 of the hydraulic accelerator 901 under test.

[0052] Specifically, the upper surface of the movable base 19, located below the protective component 2, has a first limiting slot 109 with an outward opening. One end face of the second test support rod 105, located below the protective component 2, has a second placement slot 105 with an outward opening. To ensure the stability of both ends of the hydraulic accelerator 901 under test during testing, the first limiting slot 109 is used to connect with the movable end 902, and the second placement slot 105 is used to place the fixed end 904.

[0053] Specifically, the protective assembly includes a first protective cover 21, with a front plate 26 on its front end face and a first guide wheel 201 and a second guide wheel 204 on its two side end faces; a second protective cover 22, located above the first protective cover 21, with a third guide wheel 203 and a fourth guide wheel 206 on its two side end faces; a third protective cover 23, located above the second protective cover 22, with a fifth guide wheel 205 and a sixth guide wheel 207 on its two side end faces, and a rear plate 260 on its end face away from the first protective cover 21; a side plate 29, located between the front plate 26 and the rear plate 260 and above the test hydraulic cylinder 64, with a placement notch 209 on the lower end face of the side plate 29 and above the test hydraulic cylinder 64. Multiple protective plates are stacked together to control the overall size of the protective cover area. The front plate 26 is equipped with a control motor 20. One end of the control motor 20 is rotatably connected to a spool 28. A pulley 27 is located on the upper side of the spool 28 and on the front end face of the front plate. A pull wire 202 is provided between the spool 28 and the sixth guide wheel 207. The pull wire 202 is wound around the first guide wheel 201, the second guide wheel 204, the third guide wheel 203, the fourth guide wheel 206, and the fifth guide wheel 205, respectively. The control motor 20 and the pulley 27 are fixedly connected to the front end face of the front plate through a motor base 25. To prevent excessive displacement of the protective covers between layers, a first limiting protrusion 210 is provided on the upper end face of the connection between the first protective cover 21 and the front plate 26, effectively restricting the displacement path of the second protective cover 22. For the second protective cover 22, a second limiting block 120 is provided on the front end face near the first protective cover 21, and a third limiting block 202 is provided on the lower end face of the second protective cover 22 on the side opposite to the first protective cover 21. As the second protective cover moves closer to the first protective cover, a third limiting block 202 is provided. The excessive displacement is limited by the limiting contact of the first limiting protrusion 210 and the second limiting block 120, as well as the contact between the third limiting block 202 and the other end face of the first protective cover plate 21. For the formed third protective cover plate 23, it is only necessary to set a downward protruding fourth limiting block 230 on one side end face of the second protective cover plate. The formed fourth limiting block 230 can not only serve as a limiting structure, but also as a connection between the lower end face of the third protective cover plate 23 and the upper end face of the rear plate 260 and the side plate 29.

[0054] See Figure 10In this process, power is provided by the motor 20. The winding method of the pull wire 202 and the guide wheel is as follows: each guide wheel is provided with two sets of wire grooves for winding the pull wire 202. One end of the pull wire is fixedly connected to point M of the sixth guide wheel 207. Starting from this point, it first passes through the fifth guide wheel 205, then the third guide wheel 203, then the first guide wheel 201, then the pulley 27, and finally winds onto the bobbin 28. After passing through the pulley 27 and the first guide wheel 201, it winds onto the second guide wheel 204, then through the third guide wheel 203, and then to the fourth guide wheel 206. Finally, after passing through the fifth guide wheel 205, the other end is fixed to point D of the fifth guide wheel 205. By continuously turning and flipping the bobbin 28, the movement of the second protective plate 22 on the upper end face of the first protective plate 21 and the movement of the third protective plate 23 on the upper end face of the second protective plate 22 are controlled.

[0055] When the first protective cover 21, the second protective cover 22, and the third protective cover 23 are opened, the sixth guide wheel 207 (pull line direction counterclockwise) - the fifth guide wheel 205 (pull line direction counterclockwise) - the third guide wheel 203 (pull line direction counterclockwise) - the first guide wheel 201 (pull line direction counterclockwise) rotate the pull line shaft counterclockwise to pull the protective cover plates to close and achieve opening. When the first protective cover 21, the second protective cover 22, and the third protective cover 23 are closed, the fifth guide wheel 205 (pulling the cable clockwise) - the fourth guide wheel 206 (pulling the cable clockwise) - the third guide wheel 203 (pulling the cable counterclockwise) - the second guide wheel 204 (pulling the cable clockwise) - the first guide wheel 201 (pulling the cable counterclockwise) cause the second and third protective covers to continuously move closer to the first protective cover. The second and third protective covers overlap and are located on the upper side of the first protective cover, thus opening the upper side of the entire front panel, rear panel, and side panel.

[0056] Specifically, an adjustment assembly is provided between the side plate 29 and the base plate 1. The adjustment assembly includes a hydraulic cylinder base 60, which is disposed on the upper end face of the base plate 1; and a cylinder cover 63, which is disposed on the side plate 29. A hydraulic cylinder 61 is disposed between the cylinder cover 63 and the hydraulic cylinder base 60, and a buffer spring 62 is fitted on the hydraulic cylinder 61. The hydraulic cylinder base 60 is fixedly connected to the base plate 1 by screws, and the cylinder cover 63 is fixedly connected to the side plate 29 by screws. When the hydraulic cylinder 61 rises or falls, it drives the side plate to rise or fall, thereby driving the entire protective assembly to rise or fall. The compressed buffer spring 62 buffers the force brought by the rise or fall of the hydraulic cylinder 61. Furthermore, a protective shell 5 can be provided on the upper side of the entire adjustment assembly. The protective shell 5 is fixedly connected to the side plate 29, which facilitates the up-and-down movement of the side plate 29 and protects the inner adjustment assembly. Of course, multiple sets of protruding hydraulic pipe fixing bases 13 can also be set at the upper edge of the base plate 1 to facilitate the hoisting and movement of the entire base. In use, the control signal can be sent to the hydraulic conversion platform 4 through the button of the hydraulic cylinder 61 of the electro-hydraulic control platform 3, and the hydraulic conversion platform 4 can control the working state of the hydraulic cylinder 61 to rise or fall.

[0057] In addition to the preferred embodiments described above, the present invention has other embodiments.
