DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1-Figure 3 As shown, a hydraulic steering gear test bench includes a hydraulic steering gear test bench main body 1. Before installing the hydraulic steering gear to be tested, the staff starts the driving motor 2 to drive the adjusting screw 3 to rotate. The rotating adjusting screw 3 pushes the adjusting plate 4 through the thread to drive the rotating shaft 13 to drive the roller 14 to drive the rubber sleeve 15 to roll in the slide groove provided in the hydraulic steering gear test bench main body 1. The rotating shaft 13 drives the roller 14 to drive the rubber sleeve 15 to roll and support the adjusting plate 4 to move in the slide groove provided in the hydraulic steering gear test bench main body 1, thereby reducing the friction between the hydraulic steering gear test bench main body 1 and the adjusting plate 4, making the adjustment of the adjusting plate 4 more labor-saving and convenient to operate.

[0023] When the adjusting plate 4 is adjusted and moved, the adjusting plate 4 drives the mounting assembly 5 to move synchronously. When the hydraulic steering gear is longer, the adjusting plate 4 is pushed out of the hydraulic steering gear test bench main body 1. When the hydraulic steering gear is shorter, the adjusting plate 4 is driven into the hydraulic steering gear test bench main body 1. After the adjustment is completed, the second fastening bolt 17 is tightened to adjust the installable size of the mounting plate 12 on the mounting block 11 included in the mounting assembly 5, so as to adapt to the installation of hydraulic steering gears of different lengths, facilitate the testing of hydraulic steering gears of different lengths and sizes, save the use cost, have a wider range of applications, and be more practical.

[0024] like Figure 2 and Figure 4 As shown, after the hydraulic steering gear to be tested is installed, the deflection plate 10 on the movable plate 7 can display the action state of the hydraulic steering gear output shaft during the test. As an external extension of the output shaft action, the observable angle of the test is increased, which is convenient for staff to observe. The deflection plate 10 is used to simulate the state of the output shaft when it is actually used. The test result is more precise and accurate. When testing hydraulic steering gears of different sizes, the position of the output shaft changes due to the change of the installation position. After loosening the first fastening bolt 8, the movable plate 7 can be pulled to slide on the fixed rod 6. Pulling the movable plate 7 drives the fixed cylinder 9 to drive the deflection plate 10 to move to the position of the current output shaft of the hydraulic steering gear to be tested. It can adapt to the test requirements of hydraulic steering gears of different sizes and is convenient for staff to use.

[0025] How it works

[0026] It should be noted that the utility model is a hydraulic steering gear test bench. When in use, the staff first starts the driving motor 2, and the output end of the driving motor 2 drives the adjusting screw 3 to rotate on the hydraulic steering gear test bench body 1. The rotating adjusting screw 3 pushes the adjusting plate 4 through the thread, and the adjusting plate 4 drives the rotating shaft 13 to drive the roller 14 to drive the rubber sleeve 15 to roll in the slide groove opened in the hydraulic steering gear test bench body 1. At the same time, the adjusting plate 4 drives the mounting assembly 5 to move synchronously, and then the position of the adjusting plate 4 in the slide groove opened in the hydraulic steering gear test bench body 1 is adjusted according to the size of the hydraulic steering gear to be tested. When the hydraulic steering gear is longer, the adjusting plate 4 is pushed out of the hydraulic steering gear test bench body 1. When the hydraulic steering gear is shorter, the adjusting plate 4 is driven into the hydraulic steering gear test bench body 1. After the adjustment is completed, the second fastening bolt 17 is tightened, and the second fastening bolt 17 is against one side of the fixing rod 6 to fix the position of the adjusting plate 4 on the hydraulic steering gear test bench body 1 at this time, thereby fixing the position of the mounting assembly 5 at this time, so as to achieve the purpose of adjusting the installable size and adapting to the test of hydraulic steering gears of different lengths.

[0027] After determining the installation position of the hydraulic steering gear, place the hydraulic steering gear on the mounting block 11, align the mounting hole of the hydraulic steering gear with the waist-shaped hole on the mounting plate 12, and fix it on the mounting block 11 by mounting bolts, so as to fix the hydraulic steering gear to be tested. Then, pull the movable plate 7 to slide on the fixing rod 6, and connect the deflection plate 10 on the movable plate 7 with the output shaft of the hydraulic steering gear through the transmission structure, so that when testing the output shaft of the hydraulic steering gear, the output shaft action state is displayed through the deflection plate 10, so as to achieve the purpose of increasing the observation angle.

[0028] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
