Embodiment Construction

[0026] Below in conjunction with accompanying drawing, describe structure of the present invention in detail:

[0027] see figure 1 and figure 2 , the test tool mainly includes a mounting panel 1, an angle-adjustable support device and a mounting base 7. The angle-adjustable support device is fixedly installed on the installation base 7, and the installation panel 1 is fixedly installed on the upper end of the angle-adjustable support device, and the angle with the horizontal plane can be adjusted by the angle-adjustable support device. The angle-adjustable supporting device includes an upper bracket 2, a lower bracket 6, and an angle adjustment mechanism 3 and a fixed shaft 5 connecting them.

[0028] The installation base 7 is connected with the test bench 18 through 8 bolts, and the main installation surface 1 is used for connecting with the test components. The bottom surface of the main installation surface 1 is rigidly connected with the upper bracket 2, and the u...

Abstract

The invention provides an engine suspension rigidity testing tool. The engine suspension rigidity testing tool comprises an installing panel, an angle adjusting supporting device and an installing base. The angle adjusting supporting device is fixedly installed on the installing base, the installing panel is fixedly installed at the upper end of the angle adjusting supporting device, and the angle between the installing panel and the horizontal plane can be adjusted through the angle adjusting supporting device. Installing holes suitable for installing a suspension with different fixing modes are distributed in the installing panel. The angle adjusting supporting device is adopted, an angle adjusting mechanism and a locking structure are used in cooperation, the inclined angle of the main installing plane can be adjusted at will, any inclined angle can be accurately controlled, and the engine suspension rigidity testing tool is universal for carrying out the rigidity test on the suspension at any inclined angle. The main installing plane is provided with the installing holes suitable for installing the suspension with the different modes, and the engine suspension rigidity testing tool is universal for carrying out the rigidity test on the suspension at any inclined angle. According to the engine suspension rigidity testing tool, tool manufacturing cost can be effectively reduced, and working efficiency and testing accuracy are improved.

Description

technical field [0001] The invention belongs to tooling for automobile engine components, in particular to tooling for testing engine suspension stiffness. Background technique [0002] In the current situation, the engine mount has the following problems in the stiffness test: [0003] Due to the different inclination angles when the mounts are installed, different mounts require different test fixtures. A mount with an inclination angle of 60 degrees requires the design of a test fixture with an inclination angle of 60 degrees. A mount with an inclination angle of 30° requires the design of a test fixture with an inclination angle of 30°. By analogy, when performing stiffness tests on mounts with different inclination angles, it is necessary to design a test fixture with the same inclination angle. It requires a lot of human and material resources. [0004] Since there are four-point fixed and three-point fixed mounts, a four-point fixed test fixture needs to be design...
