Technical Field
[0001] This utility model relates to the field of stone technology, specifically to a stone chamfering and grinding machine. Background Technology
[0002] Stone, as a high-end building decoration material, is widely used in interior and exterior decoration design, curtain wall decoration, and public facility construction. Currently, the most common types of stone on the market are natural stone and artificial stone.
[0003] During interior decoration, the edges of stone and slabs need to be ground to a 45-degree angle or beveled according to the design requirements. This is called chamfering. Chamfering is to remove the sharp edges of the stone and slabs, making the edges smoother. It also serves as a guide and positioning tool during assembly. However, after chamfering, the chamfered edges often become sharp, which requires further rounding to prevent the sharp edges from causing injury. Utility Model Content

[0013] The working principle and beneficial effects of this utility model are as follows:
[0014] 1. In this utility model, a stone slab is placed on top of a base plate. The angle is adjusted according to the chamfer on the stone, allowing the limiting block to slide inside the fixed plate in conjunction with the support frame. When the angle is determined, the knob is turned, which drives the screw to make the positioning block contact the outside of the fixed plate, thus fixing the position of the support frame. The electric push rod is started to adjust the height of the grinding wheel, pushing the stone slab so that it contacts the grinding wheel. This drives the grinding assembly to move the positioning plate outward, which in turn drives the spring to extend outward. The positioning plate drives the connecting ring, causing the sliding ring to slide inside the sleeve. The main spindle motor is started, which drives the rotating shaft to make the grinding wheel work. When grinding the stone, the spring rebounds and applies a downward force. The drive motor is started to drive the threaded rod to move the ball nut pair. The ball nut pair drives the support plate, causing the housing to move. This allows the grinding assembly to grind the chamfer on a straight line of the stone, making it easy to adjust the grinding angle and making the grinding more stable. Attached Figure Description

[0022] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.
[0023] Example 1
[0024] like Figures 1-5 As shown in the figure, this embodiment proposes a stone chamfering and grinding machine, including a base plate 1, a fixing block 2 fixedly connected to the bottom of the base plate 1, a drive assembly 3 installed on the outside of the base plate 1, a support plate 4 installed on the top of the drive assembly 3, an electric push rod 9 fixedly connected inside the support plate 4, a housing 5 fixedly connected to the output end of the electric push rod 9, a sliding assembly 6 installed inside the housing 5, an elastic support assembly 7 installed on the outside of the sliding assembly 6, a grinding assembly 8 installed on the top of the elastic support assembly 7, and a support column 10 fixedly connected to the bottom of the base plate 1.
[0025] Furthermore, the sliding assembly 6 includes a fixed plate 61, which is fixed inside the housing 5. A main groove 62 is formed on the outside of the fixed plate 61. A support frame 63 is slidably connected to the outside of the fixed plate 61. The support frame 63 is located inside the main groove 62. A limit block 64 is fixedly connected inside the support frame 63. The bottom of the limit block 64 is slidably connected to the top of the fixed plate 61. A screw 66 is threadedly connected to the outside of the fixed plate 61. A knob 65 is fixedly connected to the top of the screw 66. The bottom end of the screw 66 extends to the support frame 63. An internal positioning block 67 is fixedly connected. The width of the limiting block 64 is greater than the distance from the inside of the support frame 63 to the side of the main groove 62. The distance from the screw 66 to the inside of the support frame 63 is greater than the width of the limiting block 64. This allows the limiting block 64 to slide inside the fixed plate 61 in conjunction with the support frame 63. When the angle is determined, the knob 65 is rotated. The knob 65 drives the screw 66 to make the positioning block 67 contact the outside of the fixed plate 61, thus fixing the position of the support frame 63. This makes it convenient to adjust the angle of the grinding component 8 when facing the stone.
[0026] Furthermore, the elastic support component 7 includes a sleeve 71, which is fixed to the outside of the support frame 63. A sliding ring 72 is slidably connected inside the sleeve 71. A connecting ring 73 is fixedly connected to the top of the sliding ring 72. The top of the connecting ring 73 extends above the sleeve 71 and is fixedly connected to a positioning plate 74. A spring 75 is fixedly connected to the bottom of the positioning plate 74 and inside the sleeve 71. The bottom end of the spring 75 is fixedly connected to the outside of the support frame 63. By driving the grinding component 8, the positioning plate 74 is driven to move outward. The positioning plate 74 drives the spring 75 to extend outward. The positioning plate 74 drives the connecting ring 73, causing the sliding ring 72 to slide inside the sleeve 71. When grinding the stone, the spring 75 rebounds and applies a downward force, which facilitates control of the grinding depth.
[0027] Furthermore, the grinding assembly 8 includes a spindle motor 81, which is fixed on the top of the positioning plate 74. A rotating shaft 83 is fixedly installed at the output end of the spindle motor 81. A secondary groove 82 is provided on the outside of the support frame 63. The lower end of the rotating shaft 83 passes through the secondary groove 82 and a grinding wheel 84 is fixedly installed thereon. When the spindle motor 81 is started, it drives the rotating shaft 83 to make the grinding wheel 84 work, so that the chamfer can be smoothly rounded.
[0028] Furthermore, the drive assembly 3 includes a square groove 31, which is formed inside the base plate 1. A drive motor 32 is fixedly connected to the outside of the base plate 1. The output end of the drive motor 32 extends into the inside of the square groove 31 and is fixedly installed with a threaded rod 33. The threaded rod 33 is driven to connect a ball nut pair 35. The top of the ball nut pair 35 is fixedly connected to the bottom of the support plate 4. A slide rod 34 is fixedly connected inside the square groove 31. A slider 36 is slidably connected to the outside of the slide rod 34. The top of the slider 36 is fixedly connected to the bottom of the support plate 4. When the drive motor 32 is started, it drives the threaded rod 33 to move the ball nut pair 35. The ball nut pair 35 drives the support plate 4 to move the housing 5, so that the grinding assembly 8 grinds the chamfer on a straight line of the stone.
[0029] In this embodiment, the stone slab is placed above the base plate 1, and the angle is adjusted according to the chamfer on the stone so that the limiting block 64 slides inside the fixed plate 61 in conjunction with the support frame 63. When the angle is determined, the knob 65 is turned, and the knob 65 drives the screw 66 so that the positioning block 67 contacts the outside of the fixed plate 61, thus fixing the position of the support frame 63. The electric push rod 9 is activated to adjust the height of the grinding wheel 84, pushing the stone slab so that it contacts the grinding wheel 84. This drives the grinding assembly 8 to move the positioning plate 74 outward, and the positioning plate 74 moves outward. Spring 75 extends outward, positioning plate 74 drives connecting ring 73 to make sliding ring 72 slide inside sleeve 71. Start spindle motor 81 drives rotating shaft 83 to make grinding wheel 84 work. When grinding stone, spring 75 rebounds and gives downward force. Start drive motor 32 drives threaded rod 33 to move ball nut pair 35. Ball nut pair 35 drives support plate 4 to move housing 5, so that grinding assembly 8 grinds the chamfer on a straight line of stone, which is convenient to adjust the grinding angle and makes grinding more stable.
