Description

Technical Field

[0001] This utility model relates to the field of steel cabinet processing technology, and in particular to a steel cabinet weld point grinding device. Background Technology

[0002] In the production and processing of steel cabinets, in order to ensure the structural stability and appearance flatness of the steel cabinets, it is usually necessary to grind the weld points at the welded joints of the steel cabinets. Currently, the commonly used grinding equipment is a handheld belt sander.

[0003] However, due to the structural design of existing steel cabinets, the welded parts inside the cabinets usually have a certain angle. The angle formed by these welded parts varies in size, and the angle of the grinding belt of existing handheld grinders is usually fixed. It cannot be adjusted according to the actual angle of the welded parts inside the steel cabinet. When grinding these welded points with angles, the grinding belt is difficult to fully fit the weld. Not only does the operator need to constantly adjust their hand posture to try to match the angle, but it also results in incomplete and uneven grinding, which leads to low grinding efficiency and limitations.

[0004] The reason for adjusting the angle of the grinding device for the welded parts inside the steel cabinet is that if the welded parts inside the steel cabinet are not ground sufficiently, it will lead to a decline in the appearance quality of the steel cabinet, affecting the overall aesthetics of the product. In addition, weld slag is easily left at the unground corners. This weld slag can not only scratch the operators or subsequent users of the steel cabinet, but also fall off during subsequent use due to the shaking of the steel cabinet or the influence of the external environment, thereby affecting the safety of the items stored inside the steel cabinet and posing limitations. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides, for example Figure 1 The steel cabinet weld point grinding device shown includes a body 1, a grinding belt 2 is provided on one side of the body 1, and an angle adjustment unit 3 is provided on one side of the body 1. The angle adjustment unit 3 includes a rotating arm 31, a driven wheel 32 and a driving component 33.

[0026] A rotating arm 31 is located on one side of the machine body 1. One end of the rotating arm 31 is rotatably connected to the machine body 1. A drive wheel is located on one side of the machine body 1. The machine body 1 is driven to the drive wheel. A driven wheel 32 is located on the rotating arm 31. The drive wheel and the driven wheel 32 are used to drive the grinding belt 2 to rotate. A drive component 33 is located inside the rotating arm 31. The drive component 33 is driven to the driven wheel 32. The drive component 33 is used to drive the driven wheel 32 to adjust the distance between the driven wheel 32 and the drive wheel simultaneously when the rotating arm 31 adjusts its angle.

[0027] Example 1: In this example, the handheld belt sander is a common grinding device. Its core working principle is that the motor drives the drive wheel to rotate, and the drive wheel then drives the grinding belt 2, which is sleeved between the drive wheel and the driven wheel 32, to rotate synchronously through friction, forming a continuously moving grinding surface. In actual operation, the operator holds the machine body 1 and puts the high-speed rotating sanding belt against the surface of the weld point to be ground. The mechanical friction between the abrasive on the surface of the sanding belt and the weld point removes impurities such as welding slag and protrusions at the weld point, so that the surface of the weld point achieves a smooth and flat effect.

[0028] like Figures 2 to 4The steel cabinet weld point grinding device shown includes a body 1, a grinding belt 2 is provided on one side of the body 1, and an angle adjustment unit 3 is provided on one side of the body 1. The angle adjustment unit 3 includes a rotating arm 31, a driven wheel 32 and a driving component 33.

[0029] A rotating arm 31 is located on one side of the machine body 1. One end of the rotating arm 31 is rotatably connected to the machine body 1. A drive wheel is located on one side of the machine body 1. The machine body 1 is driven to the drive wheel. A driven wheel 32 is located on the rotating arm 31. The drive wheel and the driven wheel 32 are used to drive the grinding belt 2 to rotate. A drive component 33 is located inside the rotating arm 31. The drive component 33 is driven to the driven wheel 32. The drive component 33 is used to drive the driven wheel 32 to adjust the distance between the driven wheel 32 and the drive wheel simultaneously when the rotating arm 31 adjusts its angle.

[0030] The driving component 33 includes a slider 331 and a threaded rod 332. The slider 331 is slidably connected inside the rotating arm 31; the threaded rod 332 is rotatably connected inside the rotating arm 31, passing through the slider 331, and the threaded rod 332 is threadedly engaged with the slider 331. The driving component 33 also includes a drive motor 333 and a bellows-style protective cover 334; the drive motor 333 is fixedly mounted inside the rotating arm 31, and the output shaft of the drive motor 333 is fixedly mounted to the threaded rod 332; one end of the bellows-style protective cover 334 is fixedly mounted to the rotating arm 31, and the other end of the bellows-style protective cover 334 is fixedly mounted to the slider 331. A support arm 34 is provided on one side of the body 1, and a connecting strip 35 is fixedly mounted inside the support arm 34, and the connecting strip 35 is fixedly mounted to the body 1. A slot 36 is provided at the end of the support arm 34, and a protrusion 37 is fixedly mounted at the end of the rotating arm 31, and the protrusion 37 is rotatably connected inside the slot 36. A rotary motor 38 is fixedly mounted on one side of the support arm 34, and the output shaft of the rotary motor 38 is fixedly mounted to the rotary arm 31. A protective cover 39 is sleeved on the outer surface of the rotary motor 38, and the protective cover 39 is fixedly mounted to the support arm 34. A bracket 310 is fixedly mounted on one side of the protective cover 39, and a roller 311 is rotatably connected to the bracket 310.

[0031] Example 2: In this example, the rotary motor 38 on one side of the support arm 34 is started. The output shaft of the rotary motor 38 drives the rotary arm 31 to rotate until the angle of the grinding belt 2 is perfectly matched with the angle of the welding part. During this process, the change in the angle of the rotary arm 31 will cause the distance between the driving wheel and the driven wheel 32 to change. The drive motor 333 inside the rotary arm 31 is started simultaneously. The drive motor 333 drives the threaded rod 332 to rotate, which in turn pushes the slider 331 to slide inside the rotary arm 31, thereby driving the driven wheel 32 to move. This ensures that the distance between the driven wheel 32 and the driving wheel can always keep the grinding belt 2 taut. After the angle adjustment is completed, the motor inside the machine body 1 that drives the driving wheel to rotate is started. The driving wheel drives the grinding belt 2 and the driven wheel 32 to rotate at high speed. The operator holds the machine body 1 and makes the grinding belt 2 fit against the surface of the welding point to achieve efficient and uniform grinding of the welding point.

[0032] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
