[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present invention.

[0024] The quantity of any element in the drawings is for illustration rather than limitation, and any naming is only for distinction and does not have any limiting meaning.

[0025] Next, referring to several representative embodiments of the present invention, the principles and spirits of the present invention will be elaborated in detail.

[0026] A surface grinding disc provided by the present invention, as Figures 1 to 4 shown, includes a mounting base 1. A first mounting groove 11 and a second mounting groove 12 are provided on the mounting base 1. A grinding disc body 2 and a transmission shaft 3 are respectively fitted in the first mounting groove 11 and the second mounting groove 12. The grinding disc body 2 and the transmission shaft 3 are both detachably connected to the mounting base 1. Based on the bottom of the first mounting groove 11, the height of the grinding disc body 2 is higher than the height of the end face of the mounting base 1 facing the grinding disc body 2. A limit groove 121 corresponding to the second mounting groove 12 is provided on the mounting base 1. The transmission shaft 3 is provided with a mounting cavity 31 and an opening 32 communicating with the mounting cavity 31. An elastic limit assembly 33 is provided in the mounting cavity 31. The elastic limit assembly 33 elastically expands and contracts along the opening 32, and the elastic expansion and contraction assembly is movably fitted with the limit groove 121.

[0027] By adopting the above technical solution, the transmission shaft 3 does not need to penetrate through the grinding disc body 2, which can efficiently utilize the grinding area of the grinding disc body 2, helps the grinding disc body 2 better play its grinding role, can effectively avoid unnecessary friction between the grinding disc body 2 and the mounting seat 1, and under the action of the elastic limiting component 33, it makes the disassembly and assembly between the mounting seat 1 and the transmission shaft 3 more convenient. Moreover, during the operation of the equipment, it can effectively prevent the transmission shaft 3 from loosening or shifting, ensuring the stable operation of the grinding disc. At the same time, the design of the elastic limiting component 33 also has a certain buffering effect, which can reduce the vibration and noise during the operation of the equipment to a certain extent, improve the running stability of the equipment, and make the grinding disc more practical.

[0028] In this embodiment, the elastic limiting component 33 includes a limiting member 331 and an elastic member 332. The elastic member 332 is abutted and connected between the limiting member 331 and the inner wall of the installation cavity 31. The limiting member 331 includes a limiting portion 3311, a connecting portion 3312, and an adjusting portion 3313. The two ends of the connecting portion 3312 are respectively fixedly connected to the limiting portion 3311 and the adjusting portion 3313. In this embodiment, the elastic member 332 is a spring. The two groups of openings 32 are distributed vertically up and down. The limiting member 331 is arranged in a U-shaped structure for convenient operation of personnel. During the process of inserting the transmission shaft 3 into the second installation groove 12, pressing the adjusting portion 3313 can cause the whole limiting member 331 to contract into the installation cavity 31. At this time, the elastic member 332 is compressed. When the transmission shaft 3 is installed in place, releasing the pressing on the adjusting member, the elastic member 332 rebounds, so that the limiting member 331 can be tightly fitted in the limiting groove 121 to prevent the transmission shaft 3 from loosening or shifting during operation.

[0029] In this embodiment, both the limiting groove 121 and the elastic limiting component 33 include two groups, and the limiting groove 121 and the elastic limiting component 33 correspond to each other one by one. The two groups of limiting grooves 121 and the two groups of elastic limiting components 33 are symmetrically distributed on both sides of the vertical central axis of the transmission shaft 3, which helps to firmly limit the transmission shaft 3 from multiple directions and prevent it from shifting or shaking during the working process. It should be noted that the vertical central axes of the mounting seat 1 and the transmission shaft 3 coincide with each other, ensuring the position accuracy of the transmission shaft 3 on the mounting seat 1 and ensuring that the transmission shaft 3 drives the grinding disc body 2 to perform efficient grinding work.

[0030] In this embodiment, the mounting seat 1 is provided with a mounting hole 111 corresponding to the first installation groove 11. A limiting pin 112 is threadedly connected in the mounting hole 111, and the limiting pin 112 is in abutting cooperation with the grinding disc body 2 to realize the detachable connection between the grinding disc body 2 and the mounting seat 1, with simple installation and high stability.

[0031] In this embodiment, the limit pins 112 include two groups, and the two groups of limit pins 112 are symmetrically distributed on both sides of the vertical central axis of the mounting base 1. In other embodiments, the limit pins 112 can also be provided in multiple groups, and the multiple groups of limit pins 112 are evenly distributed along the circumferential direction to ensure the stability of the grinding disc body 2 mounted on the mounting base 1.

[0032] In this embodiment, the grinding disc body 2 is adhesively connected with an elastic base 21. The elastic base 21 is abutted and fitted between the grinding disc body 2 and the bottom of the first mounting groove 11. The elastic base 21 has good elasticity and deformation ability. It can play a role in buffering and dispersing force when the grinding disc body 2 is subjected to external impact or vibration, effectively reducing the direct impact on the grinding disc body 2.

[0033] In this embodiment, a plurality of grinding bodies 22 are arranged on the end face of the grinding disc body 2 away from the elastic base 21. Flow guiding grooves 23 are formed between adjacent two grinding bodies 22. The shapes and materials of the grinding bodies 22 can be selected according to different grinding requirements to meet the requirements of various materials and grinding processes, making the grinding process more accurate and efficient. In this embodiment, the grinding bodies 22 are arranged in a circular structure. In other embodiments, the grinding bodies 22 can be arranged in shapes such as rectangle and rhombus. The flow guiding grooves 23 can effectively guide the flow of grinding media (such as grinding fluid, abrasive, etc.), thereby improving the uniformity and consistency of grinding. At the same time, the flow guiding grooves 23 also help to remove the waste and impurities generated during the grinding process, keep the grinding surface clean and the grinding effect stable, and the setting of the flow guiding grooves 23 also helps to reduce the temperature during the grinding process, making the grinding disc more practical.

It is only for the purpose of facilitating the description of the solution of the present invention and simplifying the description, rather than explicitly or implicitly indicating that the device or element involved must have the specific orientation, be constructed and operated in the specific orientation. Therefore, the above terms of orientation or position relationship cannot be understood or interpreted as a limitation to the solution of the present invention.
