Description

Technical Field

[0001] The utility model relates to the technical field of cutting equipment, and more specifically, to a rotating wheel that is convenient for disassembly and assembly. Background Art

[0002] Stone cutting is an important process in modern stone processing. Traditional stone cutting equipment cuts stones through saw blades. With the progress of technology, now diamond wires are used instead of saw blades to cut stones. A single diamond wire is very long and needs to be wound multiple times on the cutting equipment to form multiple cutting lines for cutting multiple stones. Therefore, multiple rotating wheels are required to achieve the winding and transmission of the diamond wire. The rotating wheels will wear the wire grooves after long-term supporting and driving the diamond wire, resulting in the diamond wire being stuck in the wire grooves during transmission, affecting the transmission of the diamond wire. Therefore, the rotating wheels need to be frequently removed for maintenance and replacement. Since a single diamond wire is wound around multiple rotating wheels multiple times, the disassembly and assembly of the rotating wheels are difficult and the operation is troublesome. Summary of the Invention

[0005] Further, a plurality of fixing holes are formed in the first turntable, a plurality of gourd holes are formed in the second turntable, and bolts pass through the fixing holes and the gourd holes to fix the second turntable on the first turntable.

[0006] Further, a U-shaped installation groove is formed in the outer ring of the second turntable, and a protruding portion is circumferentially arranged on the inner side of the ring body.

[0007] Further, the bracket is L-shaped, and a strip-shaped hole is formed in the horizontal part of the bracket.

[0008] Further, an end cover is arranged on one side of the first turntable away from the bracket, a convex ring is arranged on the end cover, and the convex ring presses the outer ring of the bearing.

[0009] Further, a plurality of missing holes are formed in the second turntable.

[0021] Please refer to Figures 1-4 , the present utility model provides a rotatable wheel that is convenient for disassembly and assembly, including a bracket 10. In this embodiment, the bracket 10 is L-shaped. A strip-shaped hole 108 is formed in the horizontal portion of the bracket 10. The bracket 10 is locked and installed on the cutting device through the strip-shaped hole 108. The strip-shaped hole 108 can be used to finely adjust the overall position of the bracket 10 to support the diamond wire.

[0022] Please refer to Figures 1-4 , a fixed shaft 101 is installed on the bracket 10. A bearing 102 is sleeved on the fixed shaft 101. A first turntable 103 is sleeved on the bearing 102. The first turntable 103 is installed with a second turntable 104 through bolts. Specifically, a plurality of fixing holes 1031 are formed in the first turntable 103, and a plurality of gourd-shaped holes 1041 are formed in the second turntable 104. The bolts pass through the fixing holes 1031 and the gourd-shaped holes 1041 to fix the second turntable 104 on the first turntable 103. Loosen the bolts locked in the fixing holes 1031 and rotate the second turntable 104 so that the wider side of the gourd-shaped hole 1041 of the second turntable 104 is aligned with the position of the bolts, and then the second turntable 104 can be separated from the first turntable 103. During installation, the bolts are inserted from the gourd-shaped holes 1041, and then the second turntable 104 is rotated so that the bolts are placed at the narrower positions of the gourd-shaped holes 1041. Finally, the bolts are tightened to fix the second turntable 104 on the first turntable 103. The first turntable 103 is convenient for disassembly and assembly.

[0023] Please refer to Figures 1-4, a ring body 105 is sleeved outside the second turntable 104. Specifically, a U-shaped installation groove is formed on the outer ring of the second turntable 104. A convex portion is circumferentially arranged on the inner side of the ring body 105. The ring body 105 is installed in the installation groove through the convex portion. A U-shaped guiding groove 1051 is formed on the ring body 105. The ring body 105 is made of wear-resistant material. The diamond wire bypasses through the guiding groove 1051. The ring body 105 is installed on the second turntable 104. The second turntable 104 is connected to the first turntable 103 to realize the rotation of the ring body 105, playing a role in winding the diamond wire. Further, a number of missing holes 107 are formed on the second turntable 104 to reduce the overall weight of the second turntable 104, making the whole rotating wheel light and convenient for disassembly.
