[0002] In modern manufacturing, construction and home DIY projects, handheld grinders are widely used as a basic and important tool for processing the surfaces of various materials. These grinders use high-speed rotating sandpaper or grinding discs to effectively remove excess material from the surface of the material to achieve the purpose of grinding, polishing or cleaning. With the development of technology, handheld grinders have evolved into a variety of designs to adapt to different work needs and material types, including vibration, disc, belt and angle grinders.
[0003] Nevertheless, existing handheld grinder technology still faces a series of challenges in practical applications, especially in terms of operator fatigue, grinding uniformity and consistency.
[0004] Holding and operating a grinder for a long time, especially when fine control or high-intensity work is required, will cause fatigue in the operator's arms, waist and shoulders. This not only reduces work efficiency, but also increases the risk of work-related injuries. The root cause of the operator fatigue problem is that the equipment design fails to fully consider ergonomic principles, resulting in uneven weight distribution, poor operating posture and improper vibration control.
[0005] In addition, the grinding effect of handheld grinders is highly dependent on the skills and experience of the operator. Maintaining consistent grinding pressure and speed becomes particularly difficult when dealing with large areas or complex shapes. This high dependence on operating skills leads to inconsistency in grinding results, affecting the quality and appearance of the final product. In addition, the existing technology is difficult to effectively adjust surfaces of different hardness and materials, which further limits its scope of application and effect.

[0036] The following describes a grinding and leveling device according to some embodiments of the utility model with reference to the drawings. The core design concept of the utility model is: in view of the professional and complex operation of existing grinding machines, an auxiliary grinding and leveling device is designed to reduce the difficulty of operation for ordinary users. The grinding machine described in this article can be various types of handheld grinding machines.
[0037] Example 1
[0038] Figure 1 It is a schematic structural diagram of a grinding and leveling device according to an embodiment of the utility model. Figure 2 The embodiment of the utility model provides a grinding and leveling device, such as Figure 1 and Figure 2 As shown, the grinding and leveling device includes: a bottom frame 1, a middle slide 2, an adjustment mechanism 3 and a grinder 4. Among them, the bottom frame 1 is provided with a plurality of leveling members 11 for adjusting the horizontality of the bottom frame 1, and each leveling member 11 can adjust the relative distance between the corresponding part of the bottom frame 1 provided with the leveling member 11 and the grinding surface. In this embodiment, the bottom frame 1 is a four-sided frame structure. In other embodiments, the bottom frame 1 can also be designed into a frame structure of other shapes according to requirements, such as a circular or polygonal shape.
[0039] In this embodiment, the first slide rail 12 and the second slide rail 13 are arranged on two opposite sides of the bottom frame 1 for the middle slideway 2 to slide. In this embodiment, the number of leveling members 11 is four, which are bolts respectively arranged at the four corners of the bottom frame 1 of the four-sided frame structure. Each bolt can be adjusted to adjust the relative distance between the four corners of the bottom frame 1 and the grinding surface. In this way, the grinding and leveling device can be applied to various complex grinding surface requirements, and the grinder 4 can always be in a horizontal state or a state relatively parallel to the grinding surface, which reduces the difficulty of the grinding operation.
[0040] The middle slideway 2 is slidably arranged on the bottom frame 1 . Figure 3 This is an enlarged schematic diagram of the contact area between the middle slideway and the bottom frame of the embodiment of the utility model. Figure 3 As shown, in this embodiment, the middle slideway 2 includes a third slide rail 21 and a fourth slide rail 22 which are parallel to each other, and the ends of the third slide rail 21 and the fourth slide rail 22 are respectively in sliding contact with the first slide rail 12 and the second slide rail 13 of the bottom frame 1. In this way, during the grinding process, the grinding direction of the grinder 4 can be easily adjusted and switched at will. In addition, due to the support of the frame, the operator does not need to bear the weight of the grinder itself, thereby reducing the operator fatigue.
[0041] The adjusting mechanism 3 is slidably arranged on the middle slideway 2, and a grinder 4 is arranged on the adjusting mechanism 3, and the adjusting mechanism 3 can adjust the relative distance between the grinder 4 and the grinding surface. In this embodiment, the adjusting mechanism 3 includes an upper adjusting portion 31 fixedly connected to the grinder 4 and a lower adjusting portion 32 in sliding contact with the middle slideway 2, and an adjusting spring assembly 33 for adjusting the relative distance between the upper adjusting portion 31 and the lower adjusting portion 32 is arranged between the upper adjusting portion 31 and the lower adjusting portion 32. Figure 4 This is an enlarged schematic diagram of the structure of the regulating spring assembly of the utility model embodiment. Figure 4 As shown, the adjustment spring assembly 33 includes an adjustment bolt 331 and a spring 332. The setting of the adjustment mechanism 3 can preset the grinding force, ensure that the grinder outputs a continuous uniform pressure, avoid the uneven grinding phenomenon caused by manual operation, and affect the final grinding effect. Non-technical personnel can also easily operate the grinding, while reducing the complexity and fatigue of the operator's work. And it can adapt to the needs of grinding surfaces of different hardness and materials.
[0042] In actual work, first, place the grinding and leveling device of the utility model on the grinding surface that needs to be polished, which can be other scenes such as the ground or marble slab that need fine processing. Due to the integrated structure of the grinding and leveling device of the utility model, it can be considered that the horizontality of the bottom frame 1 is the horizontality of the grinding surface after grinding. On this theoretical basis, adjust the four leveling members 11 to adjust the horizontality of the bottom frame 1 to the required horizontality of the grinding surface. For general ground, the bottom frame can be adjusted to a completely horizontal state. Then, by adjusting the structure 3, adjust the height of the grinder 4, which can also be understood as adjusting the contact force (grinding pressure) between the grinder 4 and the grinding surface. After all the above are adjusted, start the grinder 4, and the staff can easily grind the grinding surface in the bottom frame 1 to be flat and uniform through the double-layer slide rail design of the utility model.
[0043] In other embodiments, the leveling member 11 may be provided with scales to more conveniently adjust the levelness of the bottom frame 1 .
[0044] Example 2
[0045] Figure 5 This is a schematic diagram of the structure of a grinding and leveling device according to another embodiment of the utility model. Figure 5 As shown, different from the embodiment 1, in this embodiment, the adjusting mechanism 3 includes a slide member 34 and an adjusting member 35 that are in sliding contact with the middle slideway 2. The adjusting member 35 connects the slide member 34 and the grinder 4 and can adjust the relative distance between the grinder 4 and the grinding surface. In this embodiment, the adjusting member (35) includes three bolts.
[0046] In actual work, the height of the grinder 4 is adjusted by adjusting the adjusting member 35 of the adjusting structure 3, which can also be understood as adjusting the contact force (grinding pressure) between the grinder 4 and the grinding surface. After starting the grinder 4, the grinder 4 can slide on the middle slide 2 by means of the sliding member 34 of the adjusting mechanism 3. The staff can easily grind the grinding surface in the bottom frame 1 flat and evenly through the double-layer slide rail design of the utility model.
[0047] Example 3
[0048] Different from the first embodiment, in the present embodiment, the bottom frame 1 of the grinding and leveling device is a circular frame structure, and no slide rail is provided on the bottom frame 1. The upper surface of the bottom frame 1 is a polishing plane, and the middle slideway 2 can slide freely on it. The present embodiment can also be expanded to be designed for polishing requirements of various surface shapes, such as polygons, ellipses, etc. The polishing machine 4 can design the size of the grinding disc according to different grinding requirements.
[0049] The grinding and leveling device of the utility model can be applied to various complex grinding surface requirements through multiple leveling parts, and can make the grinder always in a horizontal state or a state relatively parallel to the grinding surface, reducing the difficulty of the grinding operation. In addition, through the design of the double-layer slide rail, during the grinding process, the grinding direction of the grinder can be easily adjusted at will to meet the requirements of various grinding surface shapes. Moreover, since the grinder is supported by a frame, the operator does not need to bear the weight of the grinder itself, reducing the operating intensity of the operator. In addition, through the adjustment mechanism of the utility model, the grinding force and pressure of the grinder can be preset. Therefore, there is no need for professional and experienced personnel to operate, and non-technical personnel can also easily grind, reducing the complexity and fatigue of the operator's operation. In addition, the grinding and leveling device provided by the utility model can adapt to grinding surfaces of different hardness and materials, with a simple design, easy to install, debug and use.
