Description

Technical Field

[0001] This utility model relates to a spring repair device, belonging to the field of spring processing equipment. Background Technology

[0002] A spring is a mechanical part that works by utilizing elasticity. During the production of springs, burrs may be generated for the following reasons: First, during the rolling and forming stage: the raw material is squeezed or sheared by the mold during the rolling process, and tearing burrs are easily generated at the edges; Second, during the heat treatment stage: high-temperature oxidation may cause oxide scale burrs to form on the surface, or fine burrs may appear at stress concentration points after quenching; Third, during cutting and processing: such as when cutting spring wire or grinding the end face, the friction between the tool and the material may generate burrs.

[0003] Burrs on springs increase the risk of stress concentration and breakage, and also cause deviations in elastic properties, increased friction and wear. Therefore, it is necessary to remove burrs from springs.

[0004] In response, most existing equipment uses tumble polishing machines and electrolytic deburring devices to remove burrs. However, some springs are small and the number of them with this problem is small. They only need to be slightly handled manually. Using tumble polishing machines and electrolytic deburring devices may actually affect the performance of the springs.

[0005] Therefore, this utility model provides a manually operated spring adjustment device. Utility Model Content

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0023] In the description of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0024] Reference Figures 1-4 As shown, this embodiment provides a specific implementation of a spring repair device, including a box body 10 and a protrusion 20. The protrusion 20 is located in the center of the box body 10, so that two receiving cavities 30 for accommodating debris are formed inside the box body 10. This utility model includes a first groove 201 opened on the top surface of the protrusion 20, a grinding block 202 is installed in the first groove 201, and an adjustment unit 203 is installed between the grinding block 202 and the inner wall of the first groove 201. The grinding block 202 is used to grind the burrs of the spring, and the adjustment unit 203 is used to fasten the grinding block 202.

[0025] In the above technical solution, this utility model uses the grinding block 202 in the protrusion 20 to grind these small springs with a small number of them. It is easier for people to control the grinding force and avoid affecting the performance of the springs. The grinding debris falls directly into the receiving cavity 30 of the grinding block 202 for easy collection and processing. If the spring is made of metal material, a magnet can also be placed in the receiving cavity 30 to attract the debris for easy collection and utilization.

[0026] The grinding block 202 of this utility model is detachable and fixed to accommodate springs of different hardness. When cleaning the box 10, the grinding block 202 can also be removed to facilitate the cleaning of waste materials in the box 10.

[0027] In this embodiment, the bottom surface of the protrusion 20 is completely fixed to the bottom end surface of the box 10. In other embodiments, the protrusion 20 can be inclined in the box 10. Grinding the spring on the inclined end surface is less laborious and makes it easier to observe the work and effect of the spring.

[0028] In this embodiment, the adjustment unit 203 includes a spring 231 and a movable plate 232. The middle part of the movable plate 232 is fixed to the inner wall of the end of the first groove 201 by the spring 231, so that the movable plate 232 can slide in the first groove 201. When installing the grinding block 202, pressing the movable plate 232 compresses the spring 231, so that the grinding block 202 is placed into the first groove 201. Releasing the movable plate 232, the movable plate 232 is pressed tightly against the grinding block 202 under the action of the spring 231.

[0029] As one specific implementation of the polishing block 202, the polishing block 202 is a polygon with a rough surface, which can be directly used to polish the spring.

[0030] Unlike the above, in another specific implementation of the polishing block 202, the polishing block 202 includes a polishing layer 221 and a main body 222, wherein the polishing layer 221 is detachably fixed to the outer surface of the main body 222.

[0031] Furthermore, the bottom sides of the main body 222 are provided with locking blocks 223, which are detachably and fixedly connected to the end of the polishing layer 221.

[0032] Furthermore, the polishing layer 221 is made of sandpaper material, which is a material used for grinding. Sandpaper is used to grind the surfaces of metals, wood, etc., to make them smooth and shiny. It is usually made by gluing various abrasive grains onto the base paper. Depending on the different abrasive materials, there are various types such as diamond sandpaper, artificial diamond sandpaper, and glass sandpaper.

[0033] In the above technical solution, when applied to the production process, the roughness of the sandpaper surface will be smoothed out. After the above structural design, the sanding layer 221 can be replaced. First, it can replace the sandpaper that has already been smoothed. Second, different sandpaper can be selected according to the spring with different hardness, such as replacing it with diamond sandpaper, artificial diamond sandpaper, glass sandpaper, etc.

[0034] In one specific embodiment, the sandpaper material has a thickness of 0.05cm to 0.5cm, suitable for springs of different hardness.

[0035] In one specific embodiment, the box body 10 is made of plastic or stainless steel, which is lightweight, not easily corroded or rusted, and has a long service life.

[0036] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
