[0035] During the engine valve lift measurement process, accurate valve lift measurement is required. Whether this item meets the specification range is directly related to the engine test performance. During the valve lift measurement process, the hydraulic tappet and rocker arm need to be disassembled.

[0036] In the related art, when disassembling the hydraulic tappets and rocker arms of an engine, the method generally adopted is to first disassemble many parts such as the cylinder head cover and the camshaft, which is time-consuming and labor-intensive, and the efficiency of parts disassembly and recovery is low.

[0037] Furthermore, these disassembly methods are mostly manual, relying heavily on the operator's skills and experience. This can lead to inconsistent disassembly efficiency and easily introduces errors due to human factors, affecting the accuracy of subsequent valve lift measurements. As the automotive industry moves toward automation and intelligentization, higher requirements are placed on the precision, efficiency, and stability of disassembly tools.

[0038] See also Figure 1 、 Figure 2 and Figure 3 An embodiment of the present application relates to an auxiliary tool 10 for disassembling the hydraulic tappet and rocker arm of an engine, including a support base, a sliding bracket 200, a mounting base 300 and a pressing assembly 400.

Specifically, the driver 410 is used to drive the pressure member 420 toward or away from the valve spring seat. The driver 410 is an electric push rod.

[0043] By providing the driving member 410 and the pressing member 420, the driving member 410 can drive the pressing member 420 to press against the valve spring seat of the engine to compress the valve spring of the engine, so that a certain gap is generated between the top of the valve spring and the rocker arm. The rocker arm and the hydraulic tappet can be easily disassembled through the gap, and there is no need to disassemble the parts around the hydraulic tappet and the rocker arm, thereby avoiding wasting time, saving costs and improving disassembly efficiency.

[0044] Angle adjustment member 430 is connected to driver 410 and is used to adjust the angle of driver 410, thereby adjusting the angle of pressure member 420 so that the axial direction of pressure member 420 is parallel to the axial direction of the engine valve stem. By providing angle adjustment member 430, angle adjustment member 430 can adjust the angle of driver 410 so that the axial direction of pressure member 420 is parallel to the axial direction of the engine valve stem, thereby preventing the pressure member 420 from bending or damaging the valve stem when pushing the valve spring seat.

[0045] See also Figure 1 、 Figure 2 and Figure 3 According to some embodiments of the present application, optionally, the angle adjustment member 430 includes a turntable 431 and a limit member. The turntable 431 can be rotatably connected to one side of the mounting base 300. The driving member 410 is arranged on the side of the turntable 431 away from the mounting base 300.

[0049] More specifically, a plurality of first limiting pins are provided at one end of the limiting block 432 away from the mounting base 300 , and an avoidance groove is provided on the limiting block 432 , and the avoidance groove is used to avoid the turntable shaft 435 .

[0050] In this embodiment, two first stop pins are provided, one on each side of the turntable shaft 435. It should be noted that the position of the first stop pins is positively correlated with the rotation angle of the turntable 431. In this application, the rotation angle of the turntable 431 is not limited and can be set according to the desired rotation angle of the turntable 431.

[0051] See also Figure 1 、 Figure 2 and Figure 3 According to some embodiments of the present application, the mounting base 300 is optionally slidably connected to the sliding bracket 200 via a first sliding assembly 500.

The first T-shaped slider 510 is slidably connected to the first T-shaped slot 520.

[0052] More specifically, the first T-shaped sliding groove 520 extends along the X direction. Two first T-shaped sliding blocks 510 are spaced apart at the bottom of the mounting base 300 .

[0053] See also Figure 1 、 Figure 2 and Figure 3 According to some embodiments of the present application, two connecting brackets 600 are optionally provided at intervals on the sliding bracket 200. The two connecting brackets 600 are provided in a one-to-one correspondence with the two fixed brackets 100, and the two connecting brackets 600 are slidably connected to the corresponding fixed bracket 100 via a second sliding assembly 700. Specifically, the second sliding assembly 700 includes a second T-shaped slider 710 connected to the connecting bracket 600 and a second T-shaped slot 720 defined on the fixed bracket 100. The second T-shaped slider 710 is slidably connected within the second T-shaped slot 720. The connecting bracket 600 includes a first connecting member 610 and a second connecting member 620 connected to the first connecting member 610.

[0056] See also Figure 1 、 Figure 2 and Figure 3 According to some embodiments of the present application, the auxiliary tooling 10 for disassembling the hydraulic tappet and rocker arm of the engine optionally further includes a status detection module and a control module. The status detection module is used to detect the status of the pressure member 420. The status detection module is communicatively connected to the control module, and the control module is connected to the driving member 410. The control module is used to implement automated control, for example, the control module uses a single-chip microcomputer. It should be noted that the status detection module is used to detect the moving speed and stroke of the pressure member 420.

[0057] The auxiliary tool 10 for disassembling the hydraulic tappet and rocker arm of the engine further comprises a terminal control, which includes an operation interface and is communicatively connected to the control module.

[0058] The terminal inputs the set values ​​on the user interface, and the data is transmitted to the control module. The control module then controls the operation of the driver 410, driving the pressing member 420 to press against the engine's valve spring seat, compressing the valve spring to the predetermined stroke. When the spring is compressed to the predetermined stroke, the control module controls the driver 410 to stop, allowing the operator to easily disassemble the hydraulic tappet and rocker arm and replace them with hydraulic tappets and rocker arms specifically for valve lift.

[0059] During the movement of the pressure member 420, the status detection module detects the speed and travel of the pressure member 420 in real time and transmits this information to the control module, which then transmits it to the terminal control. In the event of an abnormality, the terminal control receives the abnormality information. Upon receiving the abnormality information, the terminal control transmits it to the control module, causing it to stop the driving member 410. The operator then conducts troubleshooting and troubleshooting according to the prompts provided by the terminal control.

[0060] By setting up a status detection module and a control module, the hydraulic tappet and rocker arm can be automatically disassembled, which can improve the disassembly efficiency, save time and labor, and improve the accuracy of subsequent valve lift measurement.
