The present utility model relates to grinders, particularly to a spherical grinder.
Grinders are mainly intended for grinding and polishing various workpiece surfaces; they mainly aim to smooth and finely process workpiece surfaces, remove surface defectives such as burrs, oxide scales and rust, make surfaces smoother and cleaner, and improve the quality and service life of workpieces; Grinding machines are usually divided into handhold and bench type products. A commonly used grinding disc includes a grinding wheel, a grinding belt and a polishing disc, etc; different types of grinding discs can meet different material and process requirements. For example, grinding wheel discs are intended for rough machining and deburring of metal materials, while grinding belt discs are suitable for grinding and smoothing soft materials such as wood; grinders are widely used in surface treatment, mechanical processing and home decoration regarding materials such as metals, wood and plastics; grinders can also be used for maintenance and upkeep of various tools and equipment;
A traditional grinder comprises of a grinding disc and a handle, which is quite suitable for grinding flat walls or polishing; the grinding disc can be replaced by another one depending on the needs, and the operation is very easy and practical; however, there are still some shortcomings for it; when an outer surface that needs to be polished is curved or spherical, existing grinders are always impracticable; curved or spherical surfaces are hard to be finely and ideally ground and polished, inevitably reducing the grinding process quality and efficiency, moreover, the operation is awkward and inconvenient.
The technical issue to be solved by the present utility model, considering the status quo of the prior art, is to provide a spherical grinder.
The technical solution adopted for the present utility model to solve the above technical issue discloses: a spherical grinder comprising a grinder body; the grinder body comprises a handhold part and a grinding part; the grinding part is set below the handhold part and provided with at least one grinding unit.
Preferably, the grinding units comprise grinding discs, grinding disc covers, universal balls and connecting pieces; the lower ends of the connecting pieces pass through the grinding disc covers and are connected to the grinding discs, and the upper ends of the connecting pieces are connected to the universal balls.
Preferably, through-holes are provided below the handhold part for fitting and connecting to the grinding units, and connecting joints are set in the through-holes; universal balls are set in the connecting joints, and the grinding units are connected to the handhold part through the universal balls fitting and connecting to the connecting joints.
Preferably, the handhold part is provided with a gripping part for easy holding, and the gripping part has at least one downward concavity.
Compared with the prior art, the advantage of the present utility model is that the grinding units are fit and connected to the handhold part through universal balls, the operation is flexible and can meet different angle grinding requirements, improving the grinding and polishing efficiency; and the handhold part provided with a gripping part is intended for easy holding, achieving a more friendly grip, making the control of the grinder easier and avoiding hand fatigue.

The following shows embodiments of the present utility model through drawings. For clarity, many practical details are elucidated together in the following description. However, it should be understood that these practical details should not be intended for limiting the present utility model, namely, for some embodiments of the present utility model, these practical details are not necessary. In addition, for simplifying the drawings, some common structures and components are illustrated in a simple schematic manner.
It should be noted that all directional indications relating to the embodiments of the utility model, such as up, down, left, right, front or rear . . . , only aims to explain a relative position relationship and motion of each component in a specific posture (as shown in the drawings). The directional indication changes with the change of the specific posture.
Moreover, in addition to being used for indicating directional or positional relationships, some of the above terms may also have other meanings. For example, the term “up” may also be used for representing a attachment or connection relationship. For common technicians in the art, the specific meanings of these terms regarding the present utility model can be understood depending on the specific circumstances.
Moreover, the terms “install”, “set”, “have”, “connect”, “joint”, and “attach” should be interpreted broadly. For example, they can mean a fixed connection, a detachable connection or a monolithic structure; they can mean a mechanical connection or an electrical connection; It can mean directly connected, indirectly connected through an intermediate medium, or internally connected between two devices, components or parts. The connection methods mentioned here are based on the prior art and no any improvement has been made, which are common senses for those skilled in the art, and the meanings of the above terms mentioned regarding the present utility model can be understood depending on the specific circumstances.
Moreover, words like “first” and “second” regarding the present utility model are only used for descriptive purposes; they do not particularly imply an order or a priority, and are not intended for limiting the utility model; they only aim to distinguish components or operations described with the same technical terms, and cannot be understood as indicating or implying their relative importance or implying the number of indicated technical features. Therefore, the features that are limited to “first” and “second” explicitly or implicitly include at least one of them. In addition, the technical solutions regarding various embodiments can be combined with each other, however, they must be subject to the ability of common technicians in the art; when the combination of technical solutions is contradictory or impossible to achieve, it should be considered that this combination of technical solutions does not exist and is not covered within the protection required by this utility model.
