DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] like Figure 1 As shown, a rocker arm support frame for testing includes a column 1, a beam 2, a turntable assembly 3 and a sliding assembly 4. The lower part of the column 1 is rotatably connected to the turntable assembly 3, the sliding assembly 4 is connected to the upper part of the column 1, one end of the beam 2 is connected to the sliding assembly 4, and is slidably connected to the upper part of the column 1 through the sliding assembly 4, and the other end of the beam 2 is provided with a plurality of side-by-side test windows 5, and the test window 5 is used to install a test panel.

[0027] Its working principle or implementation method is: a rocker arm that can be used for support is formed by a column 1 and a beam 2, the rocker arm swings through a turntable assembly 3, and the beam 2 moves up and down through a sliding assembly 4. After the test panel is installed on the test window 5, the test panel can be moved up and down and rotated circumferentially to better adjust the orientation of the joint on the test panel, so that the test tool connected to the test panel can be better inserted into the engine and other components, and it is also more convenient to adjust the buttons on the test panel.

[0028] During implementation, first, place the object to be tested in an appropriate position or install the above-mentioned rocker support frame for testing next to the object to be tested, for example, if the object to be tested is an engine, then adjust the angle of the turntable assembly 3 to make the crossbeam 2 in the best working posture according to the different requirements of the test items; then drive the sliding assembly 4 to move up and down along the column 1 manually or electrically until it reaches a suitable height; finally, select the corresponding test panel and install it in the designated test window 5 to start executing the specific test procedure. During the whole process, various components work together to achieve flexible construction and real-time regulation of the test environment.

[0029] According to the above working principle or embodiment, some implementation structures or implementation methods are provided. The bottom of the turntable assembly 3 is provided with a threading port, the column 1 is hollow and the upper end is provided with a connected wire outlet, and the threading port is connected to the lower end of the hollow column 1. The interior of the column 1 is cleverly designed as a hollow structure, which is specially used to accommodate various wires and data cables, greatly improving many problems caused by the clutter of cables in the past. Such a design not only improves the test efficiency, but also significantly enhances the safety of the system.

[0030] like Figure 4 As shown, the turntable assembly 3 includes a turntable 31 and a chassis 32. The upper part of the turntable 31 is fixedly connected to the column 1, and the lower part of the turntable 31 is rotatably connected to the chassis 32 through a bearing. The turntable 31 and the chassis 32 are preferably made of high-strength aluminum alloy to ensure sufficient strength and light weight; the bearing is recommended to be a deep groove ball bearing because of its strong radial load capacity and easy to obtain good lubrication conditions. In actual work, the external power source drives the column 1 to rotate, and the column 1 drives the turntable 31 fixed thereto to rotate together, while the bearing at the bottom of the turntable 31 allows the turntable 31 to rotate freely relative to the chassis 32, thereby realizing the precise angle adjustment function. Before performing the above operations, ensure that the column 1 is firmly installed in the specified position; place the turntable 31 correctly on the chassis 32 and assemble it through the bearing; adjust it to the required starting angle; regularly check the status of each component to ensure sufficient lubrication. It is also possible to replace or add components: such as adding rotating components such as rotating motors, and controlling them by remote control or other means to achieve that the turntable 31 of the turntable assembly 3 can drive the column 1 to rotate automatically. This design ensures that the turntable assembly 3 can not only achieve smooth rotation, but also is easy to install and maintain.

[0031] like Figure 1 The sliding assembly 4 shown includes a slide rail 41 and a slider 42. Figure 3 The screw rod 43, screw rod sleeve 44 and motor 45 are shown in FIG. Figure 3 and Figure 1The screw sleeve 44 is connected to the end of the beam 2 away from the test window 5, the screw 43 is meshed with the screw sleeve 44, the two ends of the screw 43 are rotatably connected in the column 1, the motor 45 is drivingly connected to one end of the screw 43, the slide rail 41 is arranged on the upper part of the column 1, the slider 42 is slidably connected to the slide rail 41, and is fixedly connected to the beam 2. The slide rail 41 can be made of high-strength aluminum alloy to ensure lightweight while maintaining sufficient rigidity and wear resistance; the slider 42 is made of self-lubricating composite material to reduce friction during movement; the screw 43 is made of precision ball screw to ensure high precision and smooth movement; the screw sleeve 44 is made of copper alloy, which has good thermal conductivity and wear resistance; the motor 45 is a stepper motor, which can provide stable driving force. The rotating shaft of the motor 45 can be connected to one end of the screw rod 43 through a coupling. When the motor 45 rotates, the screw rod 43 is driven to rotate, and the screw rod 43 is meshed with the screw rod sleeve 44, so that the screw rod sleeve 44 moves linearly along the screw rod 43, and the screw rod sleeve drives one end of the beam 2 to move linearly, and the beam 2 drives the slider 42 to slide on the slide rail 41, so that the beam 2 slides up and down along the slide rail 41. The sliding fit between the slider 42 and the slide rail 41 ensures the smooth movement of the beam 2 and reduces the vibration and noise during the movement. In practical applications, limit switches can be added on both sides of the slide rail 41 to prevent the slider 42 from exceeding the predetermined stroke; an encoder feedback system can be added to monitor the position of the slider 42 in real time to improve the positioning accuracy; a DC servo motor can also be used instead of a stepper motor to achieve smoother speed regulation and higher dynamic response.

[0032] The sliding assembly 4 with the above structure can improve the positioning accuracy and operation stability of the sliding assembly 4, ensuring that high accuracy and stability can be maintained during high-speed operation.

[0033] There are at least two slide rails 41 , which are respectively arranged on both sides of the column 1 . There are multiple sliders 42 . One end of the beam 2 away from the test window 5 is connected to a connecting plate 6 , and multiple sliders 42 are evenly distributed on the connecting plate 6 .

[0034] A first reinforcing rib plate 7 is connected between the connecting plate 6 and the crossbeam 2, and a second reinforcing rib plate 8 is connected between the slide rail 41 and the column 1. The slide rail 41 is made of high-strength aluminum alloy material to ensure good corrosion resistance and lightweight characteristics. The reinforcing rib plate is 5mm thick and is forged from high-quality carbon steel. The surface is galvanized to enhance fatigue resistance and service life. The slider 42 is made of self-lubricating material and has the characteristics of low friction coefficient and long life. During operation, the crossbeam 2 moves up and down along the slide rail 41, driving the connecting plate 6 to move synchronously. Since multiple slide rails 41 are provided, the slider 42 can evenly distribute the load in multiple directions, avoiding the problem of uneven force on a single slide rail 41. The presence of the first reinforcing rib plate 7 and the second reinforcing rib plate 8 further enhances the rigidity and stability of the entire device, effectively preventing deformation and vibration. Through such a design, the stability and carrying capacity of the test device can be significantly improved, and the positioning error caused by a single slide rail 41 can be reduced, which is particularly suitable for test occasions requiring high precision and high stability.

[0035] A test panel is installed on the test window 5. The test panel can be provided with a connector for a temperature measuring instrument, a connector for a pressure measuring instrument, and some quick-plug adapters, etc. The test panel can also be connected to the beam through a hose. When it is not needed to be pulled out, the hose is collected in the hollow beam, and the test panel is directly inserted into the test window of the beam through a quick plug. When encountering a test point inside the engine, the quick plug can be pulled out, the hose can be pulled out, and the test panel can be placed in a suitable position. Then, the pressure tester is connected through the connector and penetrated into the engine for testing. The temperature measuring instrument connector is made of high-temperature resistant material to ensure stable operation under extreme conditions; the pressure measuring instrument connector is designed with a high-pressure seal to prevent leakage. The hose material is made of high-strength flexible plastic with good aging resistance and chemical corrosion resistance. The quick-plug interface is treated with metal plating to enhance conductivity and durability.

[0036] The test panel is connected to the test cabinet through a wiring harness, which passes through the crossbeam 2, the outlet, the hollow of the column 1 and the threading port in turn and is connected to the test cabinet. When the test starts, the test panel receives data from the test object and transmits it to the test cabinet through the wiring harness for processing and analysis. During the whole process, the path formed by the wiring harness passing through the crossbeam 2, the outlet, the hollow of the column 1 and the threading port effectively avoids the influence of external factors on it, and also facilitates subsequent inspection and maintenance.

[0037] There are multiple wire troughs in the hollow of column 1, which are used to distinguish the installation harnesses. There are gaps on the surface of column 1 corresponding to the wire troughs. It is recommended to use high-strength aluminum alloy as the material of column 1, which is both light and can bear a certain weight; it is also recommended to use the same material for beam 2 to ensure the stability of the overall structure. The width of the wire trough should be slightly larger than the diameter of the cable to facilitate wiring and prevent wear. It improves the safety and reliability of cable connection and effectively prevents line damage caused by external factors. It optimizes the cable management process, making the equipment more neat and orderly, and facilitating daily maintenance and troubleshooting.

[0038] The middle of the column 1 is connected with a rotating handle 9. By adding the rotating handle 9 design in the middle of the column 1, the manual adjustment method is effectively optimized, which simplifies the overall structure and improves the user's operating experience.

[0039] The above-mentioned rocker arm support frame for testing realizes the relative independence of the test cabinet and the support frame. The test cabinet can be placed at a farther distance to form a partitioned structure of the test panel and the processing instrument. The test requirements are realized by secondary transfer of the wire harness to the gantry test panel. The hollow column 1 can realize partitioning, and a wire harness groove is reserved in the hollow inner wall. The first function is to make the routing of each panel in the beam 2 independently partitioned, and the second function is to ensure that the pipeline is relatively fixed on the column 1 to prevent the pipeline from sinking and causing the pressure point to be concentrated on the test panel. The bottom of the column 1 is designed with a turntable assembly 3 and a locking structure, which can be rotated 360 degrees by turning the handle 9. After determining the position, it is fixed by the lock. The column 1 is installed and contacted with the beam 2 through the slider 42, and the up and down movement is realized through the guide rail. The movement method can be through the motor 45, or it can be a hydraulic drive device. The motor 45 can be placed at the upper end of the column 1 opposite the beam 2. After fixing, an external protective shell is placed, and the beam 2 has a test window 5 for installing the test panel. The test window 5 is reserved with a replaceable test panel interface. The size and interface form of the test panel can be customized, but the interface must correspond to the reserved screw holes. When in use, just install the adapted panel.

[0040] Operation steps and precautions:

[0041] S1: Place the rocker support frame on a flat and solid ground to ensure it is stable and does not shake;

[0042] S2: Select the appropriate test panel according to the test requirements and install it firmly to the specified test

[0043] Window 5 position;

[0044] S3: Gently rotate the carrier assembly to turn the entire support frame to the desired test viewing angle;

[0045] S4: slowly pull the crossbeam 2 to make it rise or fall along the sliding assembly 4 to a proper height;

[0046] S5: Check whether all wiring is correct and turn on the equipment to start testing after confirming safety.

[0047] Column 1 is made of high-strength steel, and its diameter can be adjusted according to the load-bearing requirements, and its length depends on the specific application occasion; beam 2 is also made of steel, and its width must be sufficient to support the installation of the test panel, and its thickness is determined according to the bearing capacity calculation; the core parts of the turntable assembly 3 are made of wear-resistant alloy steel to ensure that it will not deform after long-term use; the power of motor 45 must meet the requirements of smooth operation under maximum load, and it is recommended to use a high-efficiency DC motor; the size and shape of the test window 5 are set according to common test panel standards, and the edges are reinforced to increase durability.

[0048] When the test angle needs to be adjusted, the operator first unlocks the lock on the turntable assembly 3, then turns the handle 9 manually or with the help of an external power source to drive the entire support frame to rotate around the bottom of the column 1 to the target position, and finally locks the lock again to fix the position. To adjust the height of the beam 2, just start the motor 45 located at the top of the column 1, and push the slider 42 up or down along the guide rail through the gear transmission mechanism until it reaches the predetermined height. In this process, the wiring harness trough in the column 1 ensures the safe layout of the power cord and other signal cables to prevent damage caused by pulling.

[0049] Replaceable parts: The column 1, the crossbeam 2, the turntable assembly 3 and the sliding assembly 4 can all be replaced with products of different specifications and models according to actual usage to adapt to more types of testing tasks.
