Embodiment Construction

[0019] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0020] The specific embodiment of spring testing machine of the present invention, as Figure 2 to Figure 4 As shown, it includes a frame 1 and a stretching stroke expansion bracket 2 fixed on the upper side of the frame 1 through a fixing structure 3. The stretching stroke expansion bracket 2 includes a protective sleeve 21 with a hollow inner cavity, which is welded and fixed on the upper end of the protective sleeve 21. The cover plate 22 and the flange plate 23 welded and fixed on the lower end of the protective cover 21. The cover plate 22 is connected with the upper draw hook 43 for cooperating with the pull-down hook 12 on the frame to stretch the tested spring, and the spring hooked between the upper draw hook 43 and the pull-down hook 12 is in the protective cover 21 to avoid spring decoupling Fly out and hurt people. For avoiding the friction...

Abstract

The invention relates to a spring testing machine to solve the problem in the prior art that the spring is easy to fall out and hurt people when the spring testing machine performs tension and compression tests on the spring. The spring testing machine of the present invention is provided with protective structure on frame, so in carrying out tensile test or compression process to the spring, when the tested spring appears eccentric and falls off from the testing machine, the spring that falls off will be in the horizontal direction. The movement can be stopped by the protective structure without flying out from the side of the rack to injure the operator, which improves the operating safety of the spring testing machine.

Description

technical field [0001] The invention relates to a spring testing machine. Background technique [0002] With the development of industry, various springs have been more and more widely used in various fields, and in many occasions and structures, springs rely on the force generated by spring deformation to function. To judge whether the spring can provide the required force under a certain deformation, it is necessary to measure the elastic coefficient of the spring. If there is a slight variation in the deformation of the spring, it will have a negative impact on the safety and practical performance of the entire structure. Therefore, tension spring and compression The measurement and detection of the spring's elastic force and its elastic coefficient is a very important part of spring application. [0003] The structure of the spring testing machine in the prior art is as figure 1 Shown, comprise frame 1, and frame 1 comprises the pull-up plate 11 of upper end, and the l...
