[0027] See Figs. 1-4 This utility model relates to an engine no-load debugging device, comprising a frame 1, a mounting plate 4 vertically fixed to the left end of the frame 1 for connecting the left side of the engine 2, and a support device 3 longitudinally moved and positioned in the middle of the frame 1 via a longitudinal translation mechanism for supporting the right side of the engine 2; the frame 1 is a rectangular frame structure, with a horizontal brace 7 and a traveling wheel 8 welded to the bottom, and a handrail 9 installed at the right end; the handrail 9 and the traveling wheel 8 facilitate the movement of the debugging device and improve the efficiency of engine 2 debugging preparation work;

[0028] The mounting plate 4 has multiple fan-shaped mounting holes 11 for mounting and connecting with the left side of the engine 2. The left side of the engine 2 is fixedly connected to the mounting holes 11 by bolts and washers. Different engines 2 are adapted to different mounting hole 11 positions to achieve left side fixation of different models of engines 2.

[0029] The longitudinal translation mechanism includes a sliding seat 5 slidably mounted on the longitudinal frame of the frame 1 and an elongated hole 12 formed on the longitudinal frame of the frame 1; the sliding seat 5 is provided with bolt holes 14, the positions of which correspond to the elongated hole 12; bolts and nuts are inserted into the elongated hole 12 and the bolt holes 14, and the sliding seat 5 is locked in the longitudinal sliding position on the frame 1 by the bolts and nuts; the support device 3 realizes the adjustment of the longitudinal position by the longitudinal sliding of the sliding seat 5;

[0030] The support device 3 includes a support assembly 10 that is laterally translatable on the longitudinal translation mechanism via a lateral translation mechanism. The support assembly 10 includes a support rod 15 that is raised and lowered to support the right side of the engine 2. The lateral translation mechanism includes a lateral guide rail 6 fixed on the sliding seat 5 of the longitudinal translation mechanism and a support seat 13 that is laterally slidably disposed on the lateral guide rail 6. In this embodiment, the lateral guide rail 6 includes two parallel open slots. The support seat 13 is an inner cylinder with internal threads. The bottom of the inner cylinder is slidably disposed on the open slots and its position is locked with the open slots by a bolt and nut structure. The lateral position of the support device 3 is adjusted by the lateral sliding of the support seat 13.

[0031] An external thread is provided on the support rod 15, which cooperates with the internal thread of the support seat 13 to realize the lifting action of the support rod 15. That is, by rotating the support rod 15, the support rod 15 can be lifted or lowered by utilizing the threaded cooperation structure between the support rod 15 and the support seat 13. The support rod 15 is provided with an adjustment rod 16 for conveniently rotating the support rod 15 to adjust its lifting position.

[0032] The longitudinal and lateral translation mechanisms enable adjustment of the lateral and longitudinal positions of the support rod 15, and the lifting and lowering of the support rod 15 enables height adjustment, thus allowing for free adaptation of the right-side support position for different engine models 2 and meeting the support requirements for the right side of different engine models 2. To meet the requirement of a certain number of support points, multiple sets of support devices 3 can be set. In this embodiment, two sets are set, using two freely adjustable longitudinal, lateral, and height support rods 15 to support different parts of the right side of the engine 2.

[0033] The left and right sides of the engine 2 are effectively fixed and supported by the mounting plate 4 and the support rod 15, respectively, which meets the installation and fixing requirements of the engine 2 for no-load debugging. By setting different mounting holes 11 on the mounting plate 4, the lateral, longitudinal displacement and height adjustment of the support rod 15 are achieved, which realizes the effective matching of different mounting support positions on the left and right sides of different engines 2. That is, the debugging device of this utility model can be used for the installation support of different models of engines 2 and meet the no-load debugging requirements.

[0034] Additionally, it should be noted that the above-described specific implementation is merely an optimized solution of this patent, and any modifications or improvements made by those skilled in the art based on the above concept are within the scope of protection of this patent.
