Problems solved by technology

[0005] In addition, the existing suspension stiffness test tool and the test bench are fastened and connected by a bolt, which is a one-point fixed installation method. The installation strength is not enough, which leads to the low constraint mode of the test tool. When performing high-frequency dynamic performance tests , prone to resonance, resulting in inaccurate test results

Embodiment Construction

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

[0027] see figure 1 with 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 upp...

Abstract

The present invention proposes a tool for testing engine mount stiffness, which includes a mounting panel, an angle-adjustable support device and a mounting base; the angle-adjustable support device is fixedly mounted on the mounting base, and the mounting panel is fixedly mounted on the angle-adjustable support device The upper end can adjust the angle with the horizontal plane through the angle-adjustable support device; the installation panel is distributed with installation holes suitable for installation of suspensions with different fixing methods. The present invention adopts the angle-adjustable support device, and the inclination angle of the main installation surface can be adjusted arbitrarily by the combination of the angle adjustment mechanism and the locking structure, which can realize the precise control of any inclination angle, and can be used for suspensions with any inclination angle. Perform a stiffness test. In addition, by setting mounting holes on the main mounting surface that are suitable for installation of mounts with different fixing methods, the stiffness test can be performed on mounts at any installation position. The invention can effectively reduce the production cost of the tooling, and improve work efficiency and test accuracy.

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...
