[0019] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0020] The overall test system is as Figure 1-2 shown.

[0021] The present invention provides a convenient, fast and effective clamping tool for the test installation process of hydraulic pumps / hydraulic motors, and at the same time simplifies the installation difficulties caused by the structure of hydraulic pumps / hydraulic motors. It includes a hydraulic drive part 1, an installation and fixing device 2 of the hydraulic pump / hydraulic motor, and a quick clamping device 3;

[0022] In the present invention, a special method for installing and positioning the hydraulic pump / hydraulic motor is used. The T-shaped plate 4 for installing and fixing the hydraulic drive part, the installation stop ring 5 of the hydraulic drive part, and the installation and fixing positioning pin 6 of the hydraulic drive part.

[0023] Implementation method: As Figure 3-4 shown, in order to meet the tests of different types of hydraulic pumps / hydraulic motors, the test stop position installation holes of the T-shaped plate 4 for installing and fixing the hydraulic drive part are enlarged to a certain extent. When testing different types of products, the inner diameter of the installation stop ring 5 of the hydraulic drive part is changed to adapt to the tests of different types of products; at the same time, in order to prevent the relative rotation between the hydraulic pump / hydraulic motor and the T-shaped plate 4 for installing and fixing the hydraulic drive part during the test, an installation and fixing positioning pin 6 of the hydraulic drive part is provided on the T-shaped plate 4 for installing and fixing the hydraulic drive part.

[0024] Hydraulic pump / hydraulic motor clamping device.

[0025] The present invention adopts multiple mechanical motion principles and hydraulic control technologies to complete the automatic control of the quick clamping device during the whole process and the quick clamping function.

[0026] Implementation method: As shown in Figure 5 、 6 、Figure 7: After the hydraulic drive component is installed in place, a clamping signal is sent to the propulsion oil cylinder 7; the propulsion oil cylinder 7 propels the propulsion moving slider 8 to move forward along the propulsion moving slide rail 9 until it approaches the propulsion moving distal proximity switch 10; the propulsion moving distal proximity switch 10 sends a signal to the clamping oil cylinder 11, and the clamping oil cylinder 11 pushes the clamping wedge block 12 to move forward; the clamping wedge block 12 pushes the rotating clamping arm 13 to rotate around the rotating clamping shaft 14 so that the clamping pressure plate 15 presses onto the hydraulic pump / hydraulic motor clamping surface; when the clamping wedge block 12 moves forward to the designated position, the hydraulic pump / hydraulic motor is clamped onto the mounting plate. At this time, the clamping oil cylinder distal proximity switch 16 sends a signal to start the machine test; after the test is completed, a signal is sent to the clamping oil cylinder 11; the clamping oil cylinder 11 drives the clamping wedge block 12 to move backward, and the clamping pressure plate 15 releases the hydraulic pump / hydraulic motor under the action of the oil pressure shock absorber 19; when the clamping oil cylinder 11 moves to the clamping oil cylinder proximal proximity switch 17, the clamping oil cylinder proximal proximity switch 17 sends a signal to the propulsion oil cylinder 7; the propulsion oil cylinder 7 drives the propulsion moving slider 8 to retract, and the clamping pressure plate 15 moves away from the hydraulic pump / hydraulic motor clamping working area; when the propulsion oil cylinder 7 moves to the propulsion oil cylinder proximal proximity switch 18, it stops moving, and the hydraulic pump / hydraulic motor can be removed from the mounting plate. The above operations are cycled to complete the installation and clamping work of the hydraulic drive component 1 during the test process.
