Description
Technical Field
[0001] The utility model relates to a grinding tool, in particular to a floor grinding disc. Background Art
[0002] With the rapid development of the construction industry, floor preparation has become a crucial component. Whether it's new building floor construction or renovation of existing buildings, higher requirements are placed on floor preparation tools (primarily floor grinders). As a key component in a floor grinder, the performance of the floor grinding disc directly affects the efficiency and quality of floor preparation.
[0003] Floor grinders smooth the work surface by rotating the grinding disc at high speed. The grinding head is the core component of the grinding disc. Conventional grinding discs rotate at different speeds on the inner and outer edges of the grinding head, resulting in different friction forces inside and outside. This can cause unstable operation and uneven grinding force. Utility Model Content
[0004] The main purpose of the utility model is to provide a floor grinding disc to solve the problems of unstable equipment operation and uneven grinding force when the existing floor grinding disc is rotating.
[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:
[0006] A floor grinding disc, comprising:
[0007] disc body;
[0008] There are multiple grinding heads, which are fixed on one end face of the disc body in the circumferential direction of the disc body. The grinding heads include a first grinding block and a second grinding block arranged vertically, and an end of the first grinding block away from the center of the disc body is fixedly connected to the middle of the second grinding block.
[0009] As a further technical solution, the first grinding block and the second grinding block are both rectangular parallelepipeds, and a line connecting the midpoint of the first grinding block in the width direction and the midpoint of the second grinding block in the length direction is collinear with the radius of the disc body.
[0010] As a further technical solution, on the end surface of the second grinding block away from the center of the disc body, both end points of the edge line close to the end surface of the disc body are located on the outer circumference of the disc body.
[0011] As a further technical solution, the first grinding block and the second grinding block have the same thickness, both between 9 mm and 11 mm.
[0012] As a further technical solution, the length of the first grinding block is between 27 mm and 29 mm, and the width is between 11 mm and 13 mm.
[0013] As a further technical solution, the length of the second grinding block is between 23mm-25mm, the width is between 7mm-9mm, and the distance between the two width-direction end faces of the second grinding block and the length-direction end faces of the first grinding block on the same side are the same, both between 5mm-7mm.
[0014] As a further technical solution, there are four grinding heads, which are evenly distributed on the disc body in the circumferential direction of the disc body.
[0015] As a further technical solution, the disc body is provided with a plurality of groups of positioning holes of different sizes, each group of positioning holes includes two positioning holes, and the two positioning holes are symmetrically arranged on both sides of the center of the disc body.
[0016] As a further technical solution, a connecting shaft is fixedly provided on the end surface of the disc body away from the grinding head, and the central axis of the connecting shaft is collinear with the central axis of the disc body.
[0017] The beneficial effects of the utility model are:
[0018] 1. The vertical arrangement of the first and second grinding blocks makes the grinding head form a "T" shape, which can adapt to the characteristics of the grinding disc rotating with a low linear speed in the middle and a high linear speed at the outer edge. As a result, when the grinding head rotates, the outer edge friction is large and the internal friction is small, which can well balance the friction between the grinding disc and the floor, making the whole equipment run more smoothly.
[0019] 2. The outer edge of the "T"-shaped grinding head structure formed by the first grinding block and the second grinding block can form a triangular structure, which makes the contact with the floor more stable, the whole machine is more stable during grinding, and the grinding force is more balanced.
[0020] 3. Compared with the "1"-shaped, arrow-shaped, arc-shaped and other shaped grinding head structures, the "T"-shaped grinding head structure formed by the first grinding block and the second grinding block has a relatively large area, high friction repeatability per rotation, and high grinding efficiency.

[0026] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0027] like Figure 1-Figure 2 As shown, the utility model proposes a floor grinding disc, which mainly includes a disc body 1 and a grinding head 2.
[0028] There are multiple grinding heads 2, which are fixed on one end face of the disc body 1 around the circumference of the disc body 1. In this embodiment, there are four grinding heads 2, which are evenly distributed on the disc body 1 around the circumference of the disc body 1. A connecting shaft 4 is fixedly provided on the end face of the disc body 1 away from the grinding head 2. The central axis of the connecting shaft 4 is colinear with the central axis of the disc body 1, which is conducive to rotating the disc body 1 on the floor grinder through the connecting shaft 4. The grinding head 2 includes a first grinding block 21 and a second grinding block 22 arranged vertically. The end of the first grinding block 21 away from the center of the disc body 1 is fixedly connected to the middle of the second grinding block 22. The vertical arrangement of the first grinding block 21 and the second grinding block 22 makes the grinding head 2 form a "T" shape, and the head of the "T" shape is located at the edge of the disc body 1, so that when the grinding head 2 rotates, the outer edge friction is large and the internal friction is small, which can well balance the friction of the grinding disc on the floor, making the whole equipment run more smoothly. The lines connecting the outer vertices of the "T"-shaped grinding head form a triangular structure, which provides more stable contact with the floor, a more stable grinding machine, and a more balanced grinding force. Furthermore, the "T"-shaped head is located at the edge of the disc body 1, which provides a larger grinding area, high friction repeatability per rotation, and high grinding efficiency.
[0029] The first grinding block 21 and the second grinding block 22 are both rectangular parallelepipeds. The line connecting the midpoint of the width direction of the first grinding block 21 and the midpoint of the length direction of the second grinding block 22 is collinear with the radius of the disc body 1, ensuring stability during grinding. On the end face of the second grinding block 22 away from the center of the disc body 1, the two end points of the edge line close to the end face of the disc body 1 are both located on the outer circumference of the disc body 1, which is conducive to enhancing the grinding effect.
[0030] In this embodiment, the thickness of the first grinding block 21 and the second grinding block 22 are the same, both between 9mm and 11mm. Preferably, the thickness of the first grinding block 21 and the second grinding block 22 are both 10mm. The length of the first grinding block 21 is between 27mm and 29mm, preferably 28mm, and the width of the first grinding block 21 is between 11mm and 13mm, preferably 12mm. The length of the second grinding block 22 is between 23mm and 25mm, preferably 24mm, and the width of the second grinding block 22 is between 7mm and 9mm, preferably 8mm. The distances between the two width-direction end faces of the second grinding block 22 and the length-direction end faces of the first grinding block 21 on the same side are the same, both between 5mm and 7mm. Specifically, the parts of the second grinding block 22 on both sides of the connection between the first grinding block 21 and the second grinding block 22 are symmetrically arranged, and both are 6mm long, which is conducive to further ensuring the smoothness of grinding.
[0031] The disc body 1 is provided with multiple groups of positioning holes 3 of varying sizes, each group of positioning holes 3 comprising two holes. The two positioning holes 3 are symmetrically arranged on either side of the center of the disc body 1. The positioning holes 3 are provided for insertion of the positioning shaft on the floor grinder, thereby limiting the circumferential position of the disc body 1 and preventing relative rotation between the grinding disc and the grinder. The multiple groups of positioning holes 3 of varying sizes can be adapted for installation on different types of grinders, providing enhanced practicality. In this embodiment, there are two groups of positioning holes 3, i.e., four positioning holes 3, each of which is located between two adjacent grinding heads 2.
[0032] The above description is only a preferred embodiment of the present invention. Obviously, the described embodiment is only a part of the embodiment of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
