Problems solved by technology

[0002] The anti-folding performance of the spring sheet is an important indicator to measure its life. The traditional fatigue test of the spring sheet uses the form of linear reciprocating push-pull to repeatedly fold and stretch the spring sheet. Since each folding and stretching needs to ensure a sufficient stroke, this fatigue test The frequency of the method is low, and the test period is long

Embodiment Construction

[0020] The present invention will be further described below in conjunction with the embodiments and drawings.

[0021] Such as Figure 1 to Figure 4 As shown, a spring plate fatigue test device includes a support plate b. The front of the support plate b is provided with a base a and a spring clamp 4, and a reciprocating swing frame 1 is installed on the base a through a swing shaft 2. The oscillating frame 1 is provided with an elastic sheet clamping position, and an elastic sheet slot is provided on the edge of the reciprocating swing frame 1, and the elastic sheet slot forms the elastic sheet clamping position, and the reciprocating swing frame 1 is connected with a reciprocating drive mechanism 3 , The elastic piece clamp 4 and the elastic piece clamping position are correspondingly arranged.

[0022] The reciprocating swing frame 1 includes a star frame 11, which includes at least two extended arms. The inner ends of the extended arms are connected to the same rotating disk,...

Abstract

The invention discloses a high-frequency and large-amplitude device for testing the fatigue of a spring piece, and the device comprises a substrate. The substrate is provided with a reciprocating swinging frame through a swinging rotating shaft, and the reciprocating swinging frame is provided with an elastic piece clamping position, and is connected with a reciprocating drive mechanism. The beneficial effects of the invention are that a conventional linear reciprocating push-pull testing mode is changed into a periodic swinging mode for testing; the center of the reciprocating swinging frame just carries out small-angle swinging, and then the elastic piece clamping position, far from the swinging rotating shaft, is enabled to have a bigger stroke; the vibration frequency can reach 1000Hz when the amplitude is 1.5 mm.

Description

Technical field [0001] The invention relates to a flexion test device, in particular to a spring sheet fatigue test device. Background technique [0002] The anti-folding performance of the spring leaf is an important indicator to measure its life. The traditional fatigue test of the spring leaf uses the form of linear reciprocating push and pull to repeatedly fold and stretch the spring leaf. Because each folding and stretching needs to ensure sufficient stroke, this fatigue test The frequency of the method is lower and the test period is longer. Summary of the invention [0003] In view of solving one or more of the above technical problems, the present invention provides a spring leaf fatigue testing device. [0004] The technical solutions are as follows: [0005] A spring plate fatigue testing device, the key is that it includes a base, on which a reciprocating swing frame is installed through a swing shaft, the reciprocating swing frame is provided with elastic sheet clamping ...
