DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below through the accompanying drawings and specific implementation examples.

[0027] The utility model provides a ceramic tile chamfering device for an angle grinder, which is a set of auxiliary tools specially designed for ceramic tile chamfering, and is composed of multiple components, including a chamfering support plate 6, a locking screw 25, a ceramic tile positioning clamping plate 18, a smooth strip component 21, an angle grinder conversion output shaft 1, an inner pressure plate, etc. These components work together to ensure the stability of the ceramic tile during the chamfering process and the accuracy of the processing.

[0028] The chamfered bracket plate 6 is the foundation of the entire device, and it provides a stable platform for fixing tiles and installing other components. A saw blade receiving groove is provided on the chamfered bracket plate, and the saw blade receiving groove is provided at the intersection of the horizontal plate and the side plate, and the saw blade receiving groove is a space formed by the grooves provided on the horizontal plate and the side plate respectively. The saw blade receiving groove can also be provided on the side plate alone, but since the design adopted in the technical solution simplifies the profile of the chamfered bracket plate 6, there is no obstacle to the expansion of the saw blade receiving groove to the horizontal plate, and the saw blade receiving groove is a cavity connected to the horizontal plate and the side plate, which is helpful for adjusting the cutting position and also helps with the assembly of components.

[0029] The design of the bracket plate takes into account tiles of different sizes and thicknesses. Through the use of the locking screws 25 and the tile positioning clamps 18, it can quickly adapt to tiles of different specifications.

[0030] The tile positioning clamp 18 is an important part of the bracket plate. It can move up and down according to the thickness of the tile to adapt to tiles of different sizes. When in use, first loosen the locking screw 25, move the clamp to a suitable position, clamp the tile, and then tighten the screw to ensure that the tile will not move during processing. It is very important to prevent processing errors caused by human errors and resistance when the saw blade is cut, which is directly related to the final processing accuracy.

[0031] The smooth bar assembly 21 is another component on the bracket plate, which is composed of a smooth bar frame 17, a roller 16 and a pin 15. The bracket plate is equipped with multiple smooth bar assemblies, which contact the upper surface and the side of the tile respectively, so that the workpiece can roll on it to reduce friction, firstly to prevent scratches on the tile surface, and secondly to make the pulling and cutting process smooth.

[0032] The angle grinder 19 is the main power source in the process of chamfering tiles. It is connected to the edge retaining inner pressure plate and the saw blade 24 through the conversion output shaft 1. In order to ensure the processing accuracy, the inner pressure plate of the angle grinder is first inserted into the output shaft of the angle grinder, and then the conversion output shaft 1 is tightened. This ensures the concentricity of the conversion output shaft and the angle grinder output shaft, avoids shaking during the cutting process, and thus ensures the accuracy of the processing.

[0033] The angle grinder conversion output shaft 1 is used to transmit the power of the angle grinder to the saw blade 24 to achieve precise cutting. The conversion output shaft 1 ensures the concentricity with the angle grinder output shaft to prevent swinging during cutting.

[0034] The edge retaining inner pressure plate is used to fix the saw blade 24 to ensure the stability of the saw blade during the cutting process. The edge retaining inner pressure plate is provided in a variety of sizes to meet different cutting requirements.

[0035] In the chamfer bracket system, different thicknesses of inner pressure plates can be selected according to the required edge size, such as 1mm, 2mm or 3mm. These inner pressure plates can be quickly replaced to meet different processing requirements. Compared with the traditional method of changing the position of the saw blade by adjusting the cutting frame screws, this method of replacing the inner pressure plate is faster and more accurate, greatly saving adjustment time and labor intensity.

[0036] The inner pressure plate 20 of the angle grinder is first inserted into the output shaft of the angle grinder, and then the conversion output shaft 1 of the angle grinder is screwed in and tightened on the output shaft of the angle grinder (the conversion output shaft 1 of the angle grinder can be used with most AC or DC angle grinders). This can ensure the concentricity of the conversion output shaft and the output shaft of the angle grinder, and avoid the vibration of the machine and the saw blade affecting the processing accuracy; then insert the bearing 3 on the head shell 4 together, and then select a 1 / 2 / 3mm inner pressure plate with a margin according to the size of the margin to be left, insert the conversion output shaft 1, and then install the saw blade 24, and finally tighten the outer pressure plate 28 of the angle grinder on the thread of the conversion output shaft.

[0037] Three types of margin inner pressure plates are installed on the chamfer bracket plate, and the margin inner pressure plates are set on the vertical plate of the chamfer bracket plate. After the spacer 11 is set in the middle hole of the margin inner pressure plate, it is tightened on the side plate of the chamfer bracket plate through the flange nut 14 and the screw 12. It is used for quick replacement of different margin sizes; compared with the method of loosening the cutter frame screws and then adjusting the saw blade position by tightening or loosening the set screws 13 to change the margin size, it is faster and more accurate. Adjusting the set screws on both sides of the cutting frame cannot ensure that the set screws on both sides are adjusted to the same distance, which will cause the saw blade to be non-parallel to the tile. Another problem is that the adjustment distance is uncontrollable, and the margin size cannot be accurately adjusted. It is necessary to try cutting multiple times, which is time-consuming, labor-intensive and wasteful of tiles.

[0038] The head shell assembly 4 is fixed on the chamfer bracket plate, and the head shell assembly is installed on the cross plate. The head shell assembly contains a mounting seat, which is mounted on the cross plate by screws. The mounting seat is also provided with a bearing seat for mounting the angle grinder conversion output shaft. The angle formed by the axis of the bearing in the bearing seat and the mating surfaces of the mounting seat and the cross plate is the same as the cutting angle of the tile. The advantage of setting the head shell assembly is that the component that realizes the angle formed by the axis of the bearing in the bearing seat and the chamfer bracket plate is completely placed on the mounting seat, which is convenient for the profile manufacturing of the chamfer bracket plate. The mounting seat can also realize the suspended setting of the grinder conversion output shaft, which can avoid too close contact with the saw blade accommodating groove, that is, the cutting groove, on the chamfer bracket plate, and leave enough space for component installation.

[0039] Ensure its stability. Slide the inner pressure plate 20 of the angle grinder into the output shaft of the angle grinder, and then tighten the conversion output shaft 1 onto the output shaft of the angle grinder to ensure concentricity. Pass the conversion output shaft 1 through the bearing 3 in the head shell 4, select an inner pressure plate of suitable size with margins to insert into the conversion output shaft 1, install the saw blade 24, and finally use the outer pressure plate of the angle grinder to axially lock the saw blade, head shell 4 and angle grinder. Put the angle grinder on its side and tie it with Velcro self-adhesive tape 7 to prevent it from rotating during processing.

[0040] Two threaded holes are provided on the back of the head shell for assembling water pipe connectors 30 for spraying water on both sides of the saw blade, which helps to better cool the saw blade and tiles and more effectively discharge the chips. This cooling system can extend the service life of the saw blade and prevent heat accumulation from damaging the tiles.

[0041] The side of the head shell is also provided with a water-blocking rubber 31 for blocking water, and the water-blocking rubber is connected to the head shell through a rubber screw 34. The water pipe joint is used to spray water on both sides of the saw blade. A protective cover can be opened and closed on the head shell assembly.

[0042] The shield 32 is made of transparent material. When it is closed on the head shell, the cutting condition of the saw blade can be observed and the operator can be protected from injury by the saw blade. When the shield is rotated open, the inner pressure plate and the saw blade can be easily replaced.

[0043] Finally, it should be pointed out that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit them. Although the utility model is described in detail with reference to the above embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above embodiments, or replace some of the technical features therein by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the utility model.
