[0002] In the field of machining, the finishing of internal holes has always faced the challenge of balancing precision, efficiency, and surface quality. Traditional reamers and honing processes, as two main hole machining techniques, each have their own insurmountable limitations. Honing tools, as a type of precision machining tool, achieve micro-cutting of the hole wall through a multi-cutting-edge structure design, representing a significant breakthrough in modern machining technology for internal hole finishing. This tool combines the high efficiency of traditional reamers with the precision of honing processes and is specifically designed to solve many problems in machining internal holes of high-hardness, thin-walled parts.

[0003] Compared with Chinese Patent Publication No. CN 217434020 U, a straight shank coated honing cutter includes a cutter body extending in a left-right direction. One end of the cutter body has a connecting end for connection with a corresponding machine tool. The cutter body is characterized by having an entry end at the other end, a grinding section between the entry end and the connecting end, the entry end being conical in shape, the radial cross-sectional dimension of the conical shape gradually decreasing in size away from the connecting section, a rounded chamfer between the end face of the entry end and the conical surface, a guide support section between the grinding section and the entry end, an extended support section between the grinding section and the connecting end, a spiral chip removal groove on the grinding section, and an abrasive coating at the intervals between adjacent chip removal grooves. The connecting end is a straight shank.

[0004] The disadvantage of the above patent is that when using a honing tool, the grinding part is prone to wear in direct contact with the part to be processed, requiring timely tool replacement, which is cumbersome and costly. Utility Model Content

[0005] The purpose of this invention is to provide a wear-resistant thin-walled honing tool to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A wear-resistant thin-walled honing tool includes a honing rod, a fixing component on the honing rod, a connecting component between the fixing components, and a grinding component between the honing rod and the connecting component; the connecting component includes a positioning sleeve, a plurality of pressure plates are evenly arranged around the middle circumference of the positioning sleeve, a through hole is opened in the middle of the pressure plate, and a locking block is provided on the top of the pressure plate.

The threaded groove 2 is evenly distributed on the outside of the honing rod 1. When the grinding block 502 is severely worn, it is not necessary to replace the entire tool, but only to replace the corresponding grinding component 5, which saves maintenance costs. By unscrewing the lower nut 304, the connecting cylinder 302 can be detached from the honing rod 1, and a new grinding component 5 can be replaced, which improves the replacement efficiency.

[0018] In this embodiment: the connecting component 4 includes a positioning sleeve 401, a plurality of pressure plates 402 are evenly arranged around the middle circumference of the positioning sleeve 401, a through hole 403 is opened in the middle of the pressure plate 402, and a locking block 404 is provided on the top of the pressure plate 402. The positioning sleeve 401 is located between the connecting cylinder 302 and the lower nut 304. The locking block 404 matches the limiting groove 303 and has a chamfered edge. The connecting cylinder 302 is rotated so that the position of the locking block 404 corresponds to the limiting groove 303. Finally, the lower nut 304 is installed and the lower nut 304 and the upper nut 301 are tightened. The locking block 404 is squeezed into the limiting groove 303, which drives the pressure plate 402 to press the insert 501, so that the grinding component 5 and the honing rod 1 are tightly connected, preventing the grinding block 502 from shifting due to vibration and improving the installation tightness.

[0019] In this embodiment: the grinding assembly 5 includes an insert 501, a grinding block 502 is provided in the middle of the insert 501, the insert 501 is located inside the pressure plate 402, and its cross-section is arc-shaped. The grinding block 502 is slidably connected to the inner wall of the through hole 403. The insert 501 is placed inside the pressure plate 402, and the grinding block 502 on the insert 501 passes through the through hole 403 on the pressure plate 402. After all the grinding assemblies 5 are installed, the connecting cylinder 302 is sleeved on the honing rod 1.

[0020] Working principle: During installation, first, put the upper nut 301 on the honing rod 1, place the insert 501 inside the pressure plate 402, and ensure that the grinding block 502 on the insert 501 passes through the through hole 403 on the pressure plate 402. After all grinding components 5 are installed, put the connecting sleeve 302 on the honing rod 1, rotate the connecting sleeve 302 so that the position of the locking block 404 corresponds to the limiting groove 303, and finally install the lower nut 304, tighten the lower nut 304 and the upper nut 301, and squeeze the locking block. Block 404 slides into the limiting groove 303, driving the pressure plate 402 to press the insert 501, so that the grinding component 5 and the honing rod 1 are tightly connected, preventing the grinding block 502 from shifting due to vibration, improving the installation tightness. When the grinding block 502 is severely worn, it is not necessary to replace the entire tool, but only to replace the corresponding grinding component 5, saving maintenance costs. By unscrewing the lower nut 304, the connecting cylinder 302 can be detached from the honing rod 1, and a new grinding component 5 can be replaced, which improves the replacement efficiency.
