Description

Technical Field

[0001] The utility model relates to the technical field of surface grinders, in particular to a surface grinder with a protective function. Background Art

[0002] A surface grinder is a type of grinding machine. It primarily uses a grinding wheel to rotate and grind workpieces to achieve the required flatness. Surface grinders are categorized by worktable shape: rectangular and circular. The primary parameters for rectangular surface grinders are width and length, while those for circular surfaces are primarily based on table diameter. Surface grinders are categorized by shaft type as horizontal or vertical. While grinding workpieces, these grinders produce debris or sparks. Conventional protective shields have a limited range, and sparks are prone to flying, potentially injuring workers. Therefore, those skilled in the art have sought to provide a surface grinder with protective features to address the issues raised in the aforementioned background technology. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. It should be noted that, unless otherwise clearly specified and limited, the terms "install", "connect", and "set" should be understood in a broad sense. For ordinary technicians in this field, the specific meanings of the above terms in this patent can be understood according to specific circumstances.

[0023] Reference Figure 1-Figure 4 A surface grinder with a protective function comprises a body 1 and a fixed table 2 and a grinding wheel 3 installed in the body 1. The fixed table 2 is movably installed (existing technology, which will not be described here). One end of the fixed table 2 is fixedly connected to an arc-shaped protective shell 4. Both sides of the protective shell 4 are slidably connected to circular side baffles 5. A connecting rod 6 is fixedly connected between the two side baffles 5. A top screw can be set between the side baffles 5 and the protective shell 4 to prevent the side baffles 5 from moving. At the same time, the side baffles 5 can be used to increase the protective effect. When not in use, the side baffles 5 can be opened for flexible use.

[0024] The inner wall of the protective shell 4 is fixedly connected with a plurality of inclined splash plates 7. The inclined splash plates 7 in the protective shell 4 reduce the splashing of flying chips and guide the flying chips into the collection box 8 for easy collection of the flying chips. The inner wall of the protective shell 4 is fixedly connected with a collection box 8 for collecting impurities. One corner of the collection box 8 is tilted downward and is fixedly connected to a discharge pipe 9.

[0025] In the present invention, a guide block 13 is fixedly connected to one side of the protective shell 4, and a rotating rod 14 is rotatably connected to one side of the guide block 13. A ball head 15 is fixedly connected to one end of the rotating rod 14, and the ball head 15 contacts the protective shell 4. A torsion spring 16 is fixedly connected between the guide block 13 and the rotating rod 14. A driving rod 18 is fixedly installed on the end of the rotating rod 14 away from the ball head 15. A sliding rod 17 is inserted at the bottom of the driving rod 18. A wedge 19 used in conjunction with the sliding rod 17 is fixedly connected to one side of the body 1. When the driving rod 18 is reset, the driving rod 18, the rotating rod 14 and the ball head 15 are rotated under the action of the sliding rod 17. Then, after the sliding rod 17 is out of contact with the wedge 19, the ball head 15 is reset under the action of the torsion spring 16, thereby knocking the protective shell 4 to prevent impurities from adhering to the protective shell 4.

[0026] In particular, a counterweight 20 is fixedly connected to the circumference of the driving rod 18 , and the counterweight 20 is used in conjunction with the torsion spring 16 .

[0027] It should be noted that a mounting box 10 is fixedly connected to one side of the machine body 1 , and a slag collecting box 11 is provided in the mounting box 10 . The slag collecting box 11 facilitates people to collect impurities.

[0028] In the present invention, two avoidance grooves 12 are provided on one side of one side baffle 5 , and the two avoidance grooves 12 cooperate with the discharge pipe 9 and the rotating rod 14 respectively to prevent the movement of the side baffle 5 from being affected.

[0029] In particular, a handle is fixedly connected to one side of the slag collecting box 11 , and the handle makes it convenient for people to take out the slag collecting box 11 .

[0030] It should be noted that one side of the slag collecting box 11 is rotatably connected to a rotating plate, and the bottom of the mounting box 10 is provided with a long strip-shaped limiting hole used in conjunction with the rotating plate, and the rotating plate is used to limit the slag collecting box 11.

[0031] Working principle: When in use, fix the workpiece to be polished on the surface of the fixed table 2, start the equipment, the fixed table 2 moves back and forth, and the grinding wheel 3 rotates and moves downward to polish the workpiece (existing technology). Before polishing, close the side baffle 5. The circular side baffle 5 increases the protection effect to prevent flying chips or sparks from flying. The flying chips generated during polishing fly into the protective shell 4. The splash guard 7 arranged obliquely in the protective shell 4 reduces the splash of flying chips and guides the flying chips to the collection box 8 for easy collection of flying chips. During the reciprocating movement, the rotating rod 14 is driven to move back and forth, and the rotating rod 14 drives the driving rod 18 to move. After the driving rod 18 contacts the inclined surface of the wedge block 19, the sliding rod 17 is retracted into the driving rod 18 and extends again after breaking contact. When the driving rod 18 is reset, the driving rod 18, the rotating rod 14 and the ball head 15 are rotated under the action of the sliding rod 17. Then, after the sliding rod 17 breaks contact with the wedge block 19, the ball head 15 is reset under the action of the torsion spring 16, thereby knocking the protective shell 4 to prevent impurities from adhering to the protective shell 4.

[0032] In this application, the structures and connection relationships that are not described in detail are all prior art, and their structures and principles are well-known technologies and will not be described in detail here.

[0033] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
