Description

Technical Field

[0001] This utility model relates to the field of glass cutting technology, and more specifically, to a glass cutting device. Background Technology

[0002] Glass is an amorphous inorganic non-metallic material, generally made from a variety of inorganic minerals as the main raw materials, with the addition of a small amount of auxiliary materials. It is widely used in buildings for wind insulation and light transmission, and is a mixture. During the assembly and processing of glass, it needs to be cut.

[0003] Existing glass cutting methods can be broadly categorized into manual cutting, mechanical cutting, and laser cutting. Mechanical and laser cutting require specialized equipment, resulting in higher operating costs, making them unsuitable for businesses or individual users with small cutting volumes. Manual cutting utilizes glass cutting blades, which traditionally require a person to hold and move them for cutting. Controlling the blade's trajectory and cutting force relies heavily on the operator's grip, leading to less than ideal control and potential deviations that affect the cutting quality. Furthermore, the fixed blade structure prevents the selection of suitable blades for different types of glass, and damage necessitates replacing the entire blade, increasing costs and reducing overall practicality, thus leaving room for improvement.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

Detailed Implementation

[0027] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0028] According to an embodiment of the present invention, a glass cutting device is provided.

[0029] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-4As shown, a glass cutting device according to an embodiment of the present invention includes a fixed rod 1 and a blade head 10. A rotating head 3 is rotatably connected to the middle of the surface of the fixed rod 1. A fixed arm 18 is welded to one end of the rotating head 3. A movable arm 16 is slidably connected to the inside of the fixed arm 18. An adjusting rod 15 is rotatably threaded to one end of the movable arm 16. One end of the adjusting rod 15 passes through one side of the movable arm 16 and is rotatably connected to a fixed block 12. Guide rods 6 are symmetrically installed on both sides of the fixed block 12, and the guide rods 6 are slidably connected to the movable arm 16. A blade head 10 is snapped onto the surface of the fixed block 12. A blade wheel 9 is installed on the surface of the blade head 10. Several sets of positioning blocks 19 are installed around the surface of the fixed rod 1, and the positioning blocks 19 are fastened to the rotating head 3. The components 20 are fixed together: a fixed rod 1, a rotating head 3, a fixed arm 18, and positioning blocks 19. The fixed rod 1 is made of high-strength aluminum alloy. A bearing is used in the middle of its surface to rotatably connect it to the rotating head 3. The bearing is a deep groove ball bearing to ensure smooth rotation of the rotating head 3 and reduce frictional resistance. One end of the rotating head 3 is fixed to the fixed arm 18 by welding using argon arc welding to ensure connection strength. Positioning blocks 19 are installed around the surface of the fixed rod 1. There are at least four sets of positioning blocks 19, which are fixed to the fixed rod 1 by screws, welding, etc. The positioning blocks 19 and the rotating head 3 are fixed by fasteners 20 (such as bolts, nuts, pins, etc.) passing through the first positioning hole 2. During installation, the rotating head 3 is first adjusted to a suitable angle, and then the fasteners 20 are tightened. The rotating head 3 can rotate 360° on the fixed rod 1, driving the fixed arm 18 to rotate. The fixing of the positioning block 19 to the rotating head 3 restricts the rotation of the rotating head 3. When performing straight cutting, fixing the rotating head 3 to the positioning block 19 ensures that the fixed arm 18 is stable and does not rotate. When performing circumferential cutting, the fixing is loosened, allowing the rotating head 3 to rotate freely. The fixed rod 1, as the basic support component of the device, provides stable support. The cooperation between the rotating head 3 and the fixed arm 18, combined with the fixing function of the positioning block 19, enables the device to achieve both straight and circumferential cutting, expanding the applicability of the device. Through the fixing of the positioning block 19 and the fastener 20, the stability of the fixed arm 18 is ensured during straight cutting, preventing the cutting trajectory from deviating and improving the cutting efficiency. Cutting precision and quality; Moving arm 16, adjusting rod 15, fixed block 12 and guide rod 6: The fixed arm 18 has a groove machined inside. The moving arm 16 and the fixed arm 18 are slidably connected through the groove. The width of the groove is adapted to the width of the moving arm 16 to ensure that the moving arm 16 slides smoothly and does not wobble. One end of the moving arm 16 is machined with an internal threaded hole. The adjusting rod 15 is rotatably connected to the moving arm 16 through the thread. One end of the adjusting rod 15 is rotatably connected to the fixed block 12 through a bearing, so that the fixed block 12 will not rotate when the adjusting rod 15 rotates. Guide rods 6 are symmetrically installed on both sides of the fixed block 12. The guide rods 6 pass through the through holes on the moving arm 16 and are slidably connected to the moving arm 16. The surface of the guide rods 6 is polished to reduce friction with the moving arm 16.Rotating the adjusting rod 15 causes the fixed block 12 to move up and down along the guide rod 6 due to the threaded connection between the adjusting rod 15 and the moving arm 16. The moving arm 16 can extend and retract within the groove of the fixed arm 18, changing the cutting range of the cutter head 10. The cooperation between the adjusting rod 15 and the fixed block 12 allows for precise adjustment of the distance between the cutter head 10 and the glass, thereby controlling the cutting force and preventing glass breakage or unsuccessful cutting due to improper cutting force. The extension and retraction of the moving arm 16 within the fixed arm 18 can adjust the cutting range according to different cutting needs, meeting diverse cutting tasks and further enhancing the practicality of the device. For the cutter head 10 and the cutter wheel 9: a T-shaped connecting groove 11 is provided on the surface of the fixed block 12, and a corresponding T-shaped connector 7 is installed on the surface of the cutter head 10. The cutter head 10 and the fixed block 12 are engaged through a T-shaped structure. Second positioning holes 8 are provided on both sides of the cutter head 10 and both sides of the fixed block 12. After completion, fasteners 20, consisting of pins, bolts, and nuts, pass through the second positioning hole 8 to fix the cutter head 10 to the fixing block 12, preventing the cutter head 10 from loosening during cutting. The cutter wheel 9 is mounted on the surface of the cutter head 10 via a shaft pin. The shaft pin, cutter head 10, and cutter wheel 9 are interference-fitted to ensure the cutter wheel 9 is securely installed. The T-shaped snap-fit ​​structure between the cutter head 10 and the fixing block 12 facilitates the disassembly and installation of the cutter head 10, allowing for the replacement of cutter heads 10 made of different materials depending on the glass material. The cutter wheel 9 is mounted on the surface of the cutter head 10 and directly contacts the glass for cutting. The detachable cutter head 10 design allows personnel to select the appropriate cutter head 10 according to the glass material. For example, the carbide cutter wheel 9 is suitable for ordinary glass, while the diamond cutter wheel 9 is suitable for hard glass such as tempered glass, improving cutting efficiency and quality. When the cutter head 10 wears out, only the cutter head 10 needs to be replaced, without replacing the entire cutter body, reducing maintenance and operating costs.

[0030] like Figure 1 As shown, a fixing plate 4 is installed on one end of the fixing rod 1, and a suction cup 5 is installed at the bottom of the fixing plate 4. The fixing plate 4 is fixed to one end of the fixing rod 1 with screws. The suction cup 5 is a high-powered vacuum suction cup, which is installed at the bottom of the fixing plate 4 with bolts. When installing the suction cup 5, first drill a hole in the fixing plate 4, then pass the bolt of the suction cup 5 through the hole, and then tighten it with a nut. (If the position of the fixing rod 1 needs to be adjusted, personnel can adjust it themselves to avoid interfering with the installation and use of the suction cup 5. The position of the fixing rod 1 does not affect the use of the structure and the realization of the function of this application, and will not be described in detail here.) The fixing plate 4 provides the mounting base for the suction cup 5. The suction cup 5 is adsorbed on the surface of the glass or the working platform to fix the fixing rod 1. The suction cup 5 can firmly adsorb the fixing rod 1 on the glass or the working platform, ensuring the stability of the device during cutting and avoiding the device from moving and affecting the cutting accuracy. When cutting circular glass or making openings, the fixing rod 1 is adsorbed on the glass surface; when cutting straight lines, it is adsorbed on the surface of the working platform, so that the fixing rod 1 is in a suitable position to meet different cutting needs.

[0031] like Figure 1 and Figure 3 As shown, first positioning holes 2 are provided on the surface of positioning block 19 and rotating head 3. The positioning holes and fasteners 20 are as follows: the first positioning holes 2 are respectively provided on the surface of positioning block 19 and rotating head 3; the second positioning holes 8 are provided on the surface of cutter head 10 and fixed block 12; and the third positioning holes 17 are provided on the surface of fixed arm 18 and moving arm 16. The fasteners 20 include bolts, nuts, pins, etc. In use, the fasteners 20 are passed through the corresponding positioning holes and then tightened or fixed. By passing the fasteners 20 through the positioning holes, different components are connected and fixed together, realizing the relative fixation between components and ensuring the stability of the position of each component during the cutting process. The cooperation between the positioning holes and the fasteners 20 enables the device to be firmly connected at the parts that need to be fixed, ensuring the stability and reliability of the device during the cutting process, thereby improving the cutting accuracy and quality, and also facilitating the disassembly and assembly of components.

[0032] like Figure 1 , Figure 2 and Figure 4 As shown, a connecting groove 11 is provided on the surface of the fixing block 12, and a connector 7 is installed on the surface of the cutter head 10. Both the connecting groove 11 and the connector 7 are T-shaped structures. Second positioning holes 8 are provided on both sides of the cutter head 10 and both sides of the fixing block 12.

[0033] like Figure 1 As shown, a third positioning hole 17 is provided on the surface of both the fixed arm 18 and the movable arm 16.

[0034] like Figure 1 As shown, a handle 14 is installed on one end of the moving arm 16. The handle 14 is installed on one end of the moving arm 16 by screws. During installation, holes are drilled in the moving arm 16, and then the screws of the handle 14 are passed through the holes and tightened to fix it. The surface of the handle 14 is designed with anti-slip to increase the friction when gripping. The handle 14 provides a gripping part for the operator, making it convenient for the operator to push or pull the moving arm 16. The design of the handle 14 makes it easier and more comfortable for the operator to operate the moving arm 16. When performing straight cutting, the operator can control the cutting trajectory and cutting range by gripping the handle 14 and pulling the moving arm 16, thereby improving the convenience of operation and cutting efficiency.

[0035] like Figure 1 and Figure 2As shown, the guide rod 6 has a positioning scale 13 on its surface. The positioning scale 13 is directly engraved on the surface of the guide rod 6 with a moderate engraving depth to ensure that the scale is clear and not easily worn. The positioning scale 13 cooperates with the adjusting rod 15 and the fixing block 12. By observing the positioning scale 13, the operator can understand the movement distance of the fixing block 12 and the cutter head 10. The positioning scale 13 provides the operator with an intuitive reference, enabling the operator to accurately control the distance between the cutter head 10 and the glass, thereby precisely controlling the cutting force, improving the accuracy and consistency of cutting, and reducing the scrap rate caused by improper cutting force.

[0036] like Figure 1 and Figure 3 As shown, there are at least four sets of positioning blocks 19. The number of positioning blocks 19 is set to ensure that the rotating head 3 can be fixed in multiple directions, avoiding the situation where the fixation is not firm or even shifts due to single-sided fixation, and ensuring the stability during straight cutting.

[0037] Working Principle: In actual use, the operator can move the position of the fixing rod 1 according to the desired shape of the glass to be cut. When cutting circular glass or openings, the fixing rod 1 can be placed directly on the surface of the glass and fixed to the glass surface by the suction cup 5 at the bottom, facilitating subsequent cutting. When cutting straight lines, the fixing rod 1 can be attached to the surface of the work platform by the suction cup 5 at the bottom, thus placing the fixing rod 1 on the side of the glass to avoid interrupting the cutting trajectory. At the same time, the rotating head 3 needs to be connected and locked to the positioning block 19 on the surface of the fixing rod 1 by the fastener 20, thereby ensuring the stability of the fixing arm 18 and preventing the cutting trajectory from deviating due to rotation during cutting, ensuring the cutting quality. The operator can also replace the cutter head 10 at the location of the cutter wheel 9 according to the type of glass to be cut. For example, the carbide cutter wheel 9 is suitable for ordinary glass, while the diamond cutter wheel 9 is suitable for hard glass such as tempered glass. Since only the cutter head 10 needs to be replaced, and the entire cutter body structure does not need to be replaced, it can... This device effectively reduces usage costs while maintaining structural flexibility for better operation. After the cutter head 10 is installed, the adjusting rod 15 can be rotated according to the glass thickness and the required cutting force. This allows the fixing block 12 to move the cutter head 10 up and down to a certain extent, changing the distance between the cutter wheel 9 and the glass. Consequently, the cutting force applied to the glass by the cutter wheel 9 is adjusted. Compared to the traditional manual gripping and pressing method, this effectively ensures stable cutting force during cutting, facilitating better cutting and avoiding the problems of excessive cutting force causing glass breakage or insufficient cutting force preventing cutting. This reduces the difficulty of cutting. After all the methods are selected, pushing the fixing arm 18 causes the rotating head 3 to rotate, achieving circular cutting, or pulling the handle 14 drives the moving arm 16 to extend, thus achieving linear cutting. The cutting size can be adjusted by adjusting the position of the moving arm 16 throughout the cutting process, making it easier to use. The device as a whole has the advantages of strong practicality, wide applicability, and flexible structure.
