Technical fields:

[0001] This utility model relates to the field of floor grinding machines, and in particular to an integrated grinding disc and a floor grinding machine using the integrated grinding disc. Background technology:

[0002] Floor grinders are used to smooth the ground. Current floor grinders, such as the Chinese patent "Multifunctional Grinding Disc of Floor Grinding Machine" (publication number CN202292464U), consist of a grinding disc body. The grinding disc body has a central through hole at its center. Around the central through hole, several sets of magnetic holes and sets of locking abrasive holes are evenly distributed on the surface of the grinding disc body. Each set of magnetic holes and locking abrasive holes consists of three through holes arranged in a triangle. Around the central through hole, several elongated grooves are evenly distributed on the surface of the grinding disc body. These elongated grooves extend to the other side of the grinding disc body with an inclined plane. Since the cutting tools (grinding heads) wear out frequently during the grinding process, they need to be replaced regularly. Because each grinding disc body in this patent has multiple cutting tools (grinding heads), the used cutting tools (grinding heads) are covered with a lot of dust, making the process of replacing multiple cutting tools (grinding heads) cumbersome and inefficient. Summary of the Invention:

[0003] In view of the above-mentioned shortcomings of the prior art, the purpose of this utility model is to provide an integrated grinding disc and a floor grinding machine using the integrated grinding disc. The integrated grinding disc and the floor grinding machine using the integrated grinding disc are reasonably designed and easy to disassemble and replace.

[0004] The present invention relates to an integrated grinding disc, characterized in that it includes a circular mounting plate and multiple grinding heads directly fixed on one side surface of the mounting plate and arranged in a circumferential direction. The mounting plate is provided with multiple positioning through holes for installation and positioning, and multiple bolt holes for installation and fixing.

[0005] Preferably, the mounting plate has a clearance hole at its center.

[0006] Preferably, the inner periphery of the aforementioned clearance hole is provided with several notches.

[0007] Preferably, the cross-section of the grinding head is circular, rectangular, arrow-shaped, trapezoidal, or T-shaped.

[0008] Preferably, the large end of the T-shaped and trapezoidal grinding heads is close to the outer periphery of the mounting plate, the small end of the T-shaped and trapezoidal grinding heads is far away from the outer periphery of the mounting plate, and the symmetrical center plane of each T-shaped and trapezoidal grinding head passes through the axis of the mounting plate.

[0009] Preferably, the center point of each of the above-mentioned circular grinding heads falls on a concentric circle of the mounting plate.

[0010] Preferably, the rectangular grinding head includes a first rectangular grinding head and a second rectangular grinding head, which are spaced apart. The symmetrical center plane of the first rectangular grinding head passes through the axis of the mounting plate, and the plane containing the long side of the second rectangular grinding head forms an acute angle with the plane containing the long side of the first rectangular grinding head.

[0020] This utility model of an integrated grinding disc includes a circular mounting plate 1 and multiple grinding heads 2 directly fixed on one side surface 101 (the lower surface during operation) of the mounting plate 1 and arranged in a circumferential direction. The mounting plate 1 is provided with multiple positioning through holes 3 for installation and positioning, and multiple bolt holes 4 for installation and fixing. The multiple grinding heads 2 are fixed on the mounting plate 1 during production. The grinding heads and the mounting plate can be fixed by welding or bonding. The mounting plate 1 can be made of materials such as 45# steel, and the grinding heads can be made of materials such as tool steel, tungsten steel, or diamond.

[0021] The positioning through holes 3 are used to position the grinding disc body 7 (mounted on the flange 13 of the output shaft 12 of the gearbox) with a number of positioning pins 5. The bolt holes 4 are used to correspond one-to-one with a number of threaded holes 6 on the lower surface of the grinding disc body 7 for bolt locking. That is, the positioning pins 5 and the threaded holes 6 can be installed on a grinding disc body 7, which is locked to the lower part of the output rotating shaft by the flange 13, etc.

[0022] Multiple grinding heads 2 can be arranged either evenly or non-evenly.

[0023] The cross-section of the grinding head can be circular, rectangular, arrow-shaped, trapezoidal, T-shaped, etc., and there are countless specific shapes. Only a few examples are listed here.

[0024] In one embodiment, the large ends of the T-shaped and trapezoidal grinding heads are close to the outer periphery of the mounting plate, while the small ends are far from the outer periphery of the mounting plate. Furthermore, the symmetrical center planes of each T-shaped and trapezoidal grinding head pass through the axis of the mounting plate (e.g., ...). Figure 3 (As shown).

[0025] In one embodiment, the center point of each circular grinding head falls on a concentric circle of the mounting plate (e.g., ...). Figure 1 (As shown).

[0026] In one embodiment, the rectangular grinding head includes a first rectangular grinding head 201 and a second rectangular grinding head 202. The first rectangular grinding heads 201 are evenly distributed in an array around the circumference of the mounting plate, and the second rectangular grinding heads 202 are also evenly distributed in an array around the circumference of the mounting plate. The first and second rectangular grinding heads are spaced apart (in the circumferential direction). The symmetrical center plane of the first rectangular grinding head passes through the axis of the mounting plate, and the face containing the long side of the second rectangular grinding head forms an acute angle with the face containing the long side of the first rectangular grinding head (e.g., ...). Figure 5 (As shown).

[0027] In order to avoid the installation of bolts 8 on the grinding disc body 7 (the bolts 8 are used for interconnection within the flange 13 and are existing technology), there is a clearance hole 9 in the center of the mounting plate. The grinding disc body 7 has multiple countersunk holes and countersunk bolts 14 installed in the countersunk holes. These countersunk bolts are used to connect the grinding disc body 7 to the flange 13. The flange 13 is connected and fixed to the output rotating shaft 12 by a key engagement.

[0028] To ensure the strength of the mounting plate, several notches 10 (which can be arc-shaped notches) are provided along the inner circumference of the aforementioned clearance hole 9. These notches 10 also serve to accommodate the bolt 8. While a larger diameter could be chosen for the clearance hole 9 on the mounting plate to accommodate the bolt 8, this would reduce the strength of the mounting plate. Therefore, by providing notches 10 while ensuring the clearance of the bolt 8, the diameter of the clearance hole 9 can be reduced (e.g., ...). Figure 5 (As shown).

[0029] The present invention relates to a floor grinding machine, which includes a gearbox 11 (the gearbox is prior art and will not be described in detail here) and several output rotating shafts 12 extending through the lower surface of the gearbox. A grinding disc body 7 is connected to the output rotating shafts via flanges 13 (the above connection is prior art and will not be described in detail here). A plurality of positioning pins 5 are provided on the lower surface of the grinding disc body 7 for positioning the mounting plate 1, and the mounting plate is locked to the grinding disc body 7 by bolts.

[0030] This utility model's integrated grinding disc allows for the direct mounting of multiple grinding heads onto the mounting plate. This eliminates the need to install multiple grinding discs separately on the grinding disc body, thus improving the efficiency of changing multiple grinding heads and greatly facilitating use.

[0031] The above description is only a preferred embodiment of this utility model. For those skilled in the art, designing different forms of a novel prefabricated steel plate composite shock-absorbing wall design method that considers multi-stage stress based on the teachings of this utility model does not require creative labor. All equivalent changes, modifications, substitutions and variations made in accordance with the scope of the patent application of this utility model without departing from the principles and spirit of this utility model shall be covered by this utility model.
