Description

Technical Field

[0001] This utility model relates to the field of wave-shaped spring technology, specifically a wave-shaped spring structure. Background Technology

[0002] A corrugated spring is a wave-shaped ring-shaped elastic element, usually made of stainless steel (such as 304 / 316 grade) or spring steel. Its corrugated structure gives it excellent elastic deformation ability and can generate uniform elastic force under axial pressure. It is mainly used in bolt fastening scenarios to provide continuous preload to prevent loosening (such as motor bearings and mechanical assemblies), while absorbing vibration and compensating for dimensional changes caused by thermal expansion and contraction. It is suitable for various precision equipment and industrial fields.

[0003] The existing wavy spring has a small contact area between the top and bottom during use, resulting in poor stability. Placing shims directly between the top and bottom of the spring can easily cause misalignment between the two shims, further reducing stability.

[0004] Based on this, a wave-shaped spring structure is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0005] The purpose of this invention is to provide a wave-shaped spring sheet structure to solve the problem of poor stability of spring sheets in the prior art.

[0008] The bottom of the spring body is provided with a second pad, and the top of the second pad is provided with a second positioning groove at equal intervals in a ring. The second positioning groove is adapted to the spring body, and a positioning component is provided between the second pad and the first pad.

Each of the multiple positioning sleeves has a positioning rod slidably installed inside, and the positioning rod is fixedly connected to the second pad.

[0012] In one alternative: the top of the spring body is provided with equidistant annular positioning holes, and the positioning rod passes through the positioning holes to penetrate the spring body.

[0016] In one alternative: the hydrophobic layer is made of a polyolefin hydrophobic coating.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0027] In one embodiment, such as Figures 1-5 As shown, a wave-shaped spring sheet structure includes a spring sheet body 1, a first pad 2 is provided on the top of the spring sheet body 1, and a first positioning groove 3 is provided at equal intervals in a ring at the bottom of the first pad 2, and the first positioning groove 3 is adapted to the spring sheet body 1.

[0028] The bottom of the spring body 1 is provided with a second pad 6, and the top of the second pad 6 is provided with a second positioning groove 7 at equal intervals in a ring. The second positioning groove 7 is adapted to the spring body 1, and a positioning component is provided between the second pad 6 and the first pad 2.

[0029] In this embodiment, the cooperation of the first positioning groove 3 and the second positioning groove 7 makes the spring body 1 stably installed between the first pad 2 and the second pad 6. The first pad 2 and the second pad 6 increase the contact area between the top and bottom of the spring body 1, making the spring body 1 more evenly stressed. The positioning component further improves the stability between the first pad 2, the spring body 1 and the second pad 6, making it safer to use.

[0030] In one embodiment, such as Figure 1 and Figure 3 As shown, the first pad 2 has a first anti-slip pad 4 on its top and the second pad 6 has a second anti-slip pad 8 on its bottom. The first pad 2 has a first through hole 10 at the top center point and the second pad 6 has a second through hole 11 at the top center point. The friction of the spring is improved by the first anti-slip pad 4 and the second anti-slip pad 8, making it less prone to loosening during use. The first anti-slip pad 4 and the second anti-slip pad 8 are made of rubber, which has a certain cushioning effect.

[0031] In one embodiment, such as Figure 1 and Figure 3As shown, the positioning assembly includes multiple positioning sleeves 5, which are equidistantly and annularly fixedly connected to the bottom of the first pad 2. Positioning rods 9 are slidably installed inside each of the multiple positioning sleeves 5, and the positioning rods 9 are fixedly connected to the second pad 6. Positioning holes 12 are equidistantly and annularly opened at the top of the spring body 1. The positioning rods 9 penetrate the spring body 1 through the positioning holes 12. When the spring body 1 deforms, the cooperation between the positioning sleeves 5 and the positioning rods 9 ensures that the positions of the first pad 2 and the second pad 6 will not shift, improving the overall stability of the spring and making it safer to use.

[0032] In one embodiment, such as Figure 1 and Figure 3 As shown, the spring body 1 includes a carbon steel layer 101, a phosphate layer 102 is attached to the outside of the carbon steel layer 101, an electroplated layer 103 is attached to the outside of the phosphate layer 102, and a hydrophobic layer 104 is attached to the outside of the electroplated layer 103. The electroplated layer 103 is made of zinc-nickel alloy, and the hydrophobic layer 104 is made of polyolefin hydrophobic coating. The phosphate layer 102 enhances the adhesion of the coating and the rust prevention ability of the carbon steel layer 101. The electroplated layer 103 is covered by electroplating or vacuum coating process to provide basic corrosion protection. The hydrophobic layer 104 covers the surface of the contact point to achieve automatic isolation upon contact with liquid, improve the rust prevention function, and effectively extend the service life of the spring.

[0033] The above embodiment discloses a wave-shaped spring sheet structure, wherein the positioning hole 12 is aligned with the positioning rod 9 to install the spring sheet body 1 and the second washer 6, and the positioning sleeve 5 is aligned with the positioning rod 9 to install the first washer 2 and the second washer 6. Through the cooperation of the first positioning groove 3 and the second positioning groove 7, the spring sheet body 1 is stably installed between the first washer 2 and the second washer 6, and the first washer 2 and the second washer 6 increase the contact area between the top and bottom of the spring sheet body 1, making the force on the spring sheet body 1 more uniform. When the spring sheet body 1 deforms... At the same time, due to the cooperation between the positioning sleeve 5 and the positioning rod 9, the positions of the first pad 2 and the second pad 6 will not shift, which improves the overall stability of the spring. The friction of the spring is improved by the first anti-slip pad 4 and the second anti-slip pad 8, making it less prone to loosening during use. The phosphate layer 102 enhances the coating adhesion and the rust prevention ability of the carbon steel layer 101. The electroplating layer 103 is covered by electroplating or vacuum coating process to provide basic corrosion protection. The hydrophobic layer 104 covers the surface of the contact point, realizes automatic isolation when encountering liquid, improves the rust prevention function, and effectively extends the service life of the spring.
