Technical Field

[0001] This utility model relates to the field of disc cutter technology, specifically a disc cutter that can be quickly assembled. Background Technology

[0002] In modern industrial production, disc cutters are widely used in packaging, metal processing, and plastics manufacturing industries due to their high-efficiency cutting capabilities. As market competition intensifies and companies increasingly prioritize production efficiency, the assembly efficiency of disc cutters has become a crucial factor affecting production line operating speed and overall production effectiveness. In response, Chinese patent application number CN202123156986.6 discloses a disc-shaped pipe cutter, relating to the field of cutting tool technology. This disc-shaped pipe cutter includes: a cutter body for fixed connection with a cutter shaft, the cutter body extending circumferentially to form a cutting edge, the cutter body having a through hole that mates with the cutter shaft, and a wear-resistant ring disposed around the inner surface of the through hole.

A side nut 130 is abutted and supported on the outer side of the side abutment ring 120 and threaded onto the outer wall of the auxiliary insert 110. A back abutment ring 111 is integrally provided on the left side of the auxiliary insert 110, and a limit pin 112 is integrally provided on the right side of the back abutment ring 111. The limit pin 112 is inserted into the side inside the disc cutter body 100. An inner shaft pin 141 is inserted through the inner end of the inner abutment plate 140, and inner support feet 142 are fixed at both ends of the inner shaft pin 141. The inner support feet 142 are fixed to the inner wall of the auxiliary insert 110, and the inner abutment feet 122 are integrally fixed inside the side abutment ring 120. Therefore, during assembly and use, it is convenient to combine and support the auxiliary insert 110 and the disc cutter body 100, which makes it easy to disassemble in parts later, thus realizing the whole into parts and disassembling them individually, and also facilitating rapid assembly later.

[0017] As described in more detail in this embodiment, the auxiliary insert 110 has an inner card seat 113 integrally fixed on the outer wall of the middle part, and the disc cutter body 100 has an inner card groove 101 corresponding to the inner card seat 113 inside, and a side slot 102 corresponding to the limiting pin 112 is opened inside the side of the disc cutter body 100.

[0018] Therefore, during assembly and use, it is convenient to assist in the fitting and locking of the disc cutter body 100, making operation and use more convenient; with the cooperation of the inner clasp 113 and the limit pin 112, it is convenient to assist in the fitting and assembly of the disc cutter body 100. As described in more detail in this embodiment, the right side of the disc cutter body 100 is supported by a front retaining ring 114, and the front retaining ring 114 and the back abutment ring 111 are symmetrically arranged. The outer end of the limiting pin 112 is inserted into the side of the front retaining ring 114. The right side of the front retaining ring 114 abuts against and supports a limiting screw sleeve 115, and the limiting screw sleeve 115 is threaded onto the outer wall of the auxiliary insert 110 and is fastened by inserting and fastening screws 116.

[0019] Therefore, during assembly and use, it is convenient to provide auxiliary limiting support according to the needs of use, making subsequent assembly more convenient and stable; As described in more detail in this embodiment, the auxiliary insert 110 has an inner sleeve through hole 117 inside, and the side of the inner sleeve through hole 117 is hexagonal, with six sets of inner abutment pieces 140 evenly distributed on the inner wall of the inner sleeve through hole 117. This facilitates the limiting assembly inside the auxiliary insert 110, making subsequent operation and use more convenient; As described in more detail in this embodiment, the outer end of the inner abutment 140 is arc-shaped and the inner side of the inner abutment foot 122 is inclined. Six sets of inner abutment feet 122 are evenly distributed on the inner wall of the side abutment ring 120, and the inner abutment feet 122 are engaged on the side wall of the auxiliary insert 110. The side wall of the auxiliary insert 110 is provided with a side sliding groove 123 corresponding to the inner abutment foot 122. Therefore, during assembly and use, the inner foot 122 provides auxiliary support to the corresponding inner abutment piece 140, making operation and use more convenient.

[0020] As more detailed in this embodiment, the auxiliary insert 110 is provided on both sides, and the right side of the auxiliary insert 110 is also provided with an inner abutment 140. The right side of the auxiliary insert 110 is fitted with an auxiliary abutment ring 121 and an auxiliary nut 131 corresponding to the side abutment ring 120 and the side nut 130.

[0022] Therefore, during assembly and use, it is convenient to provide auxiliary limiting support for the auxiliary insert 110, so that the auxiliary insert 110 can be fitted onto the drive end of the equipment shaft for auxiliary support and limiting.

[0023] Working principle: During assembly and use, the opening of the inner through hole 117 facilitates the fitting and support of the auxiliary insert 110 on the drive output end of the equipment shaft. Subsequently, with the cooperation of the side abutment ring 120 and the inner abutment foot 122, the auxiliary abutment inner abutment piece 140 provides limiting support for the auxiliary insert 110 and the equipment shaft end. As the side nut 130 is tightened, it is easy to maintain the supporting contact between the side abutment ring 120 and the inner abutment foot 122 and the inner abutment piece 140, thereby facilitating the limiting support assembly of the auxiliary insert 110 and the equipment shaft, which is conducive to subsequent stable driving. At the same time, the limiting support can also be achieved by tightening the rear locking pin 118. Subsequently, with the cooperation of the back abutment ring 111 and the limiting pin 112, the disc cutter body 100 is easily positioned and supported. Then, with the cooperation of the front retaining ring 114 and the limiting screw 115, the limiting screw 115 is tightened, making it easier for the disc cutter body 100 to be supported and supported, thus achieving assembly and facilitating subsequent use. When disassembly and maintenance are required, the disc cutter body 100 can be disassembled individually instead of the whole body, which also facilitates quick reassembly. The operation ends here.
