Technical Field

[0001] The utility model relates to the technical field of grinding, and particularly relates to an adjustable honing rod. Background Art

[0002] Honing, also known as boring and grinding, is a finishing process that uses oilstones embedded in a honing head to finish a machined surface. The Chinese utility model patent with the authorization announcement number "CN219599093U" discloses an adjustable honing rod for deep holes, which includes a rod body, an adjusting mechanism, a reinforcement device, and a honing head, so as to adjust the overall length of the honing rod to adapt to honing holes of different depths. However, due to the existence of the adjusting column, a part of the original inserted column will be exposed outside, and the connection between the parts in the overall structure is no longer airtight, resulting in instability. In order to reinforce and stabilize, a reinforcement plate is provided. The reinforcement plate is movably sleeved on the first rod body. After the first rod body is connected to the second rod body, the baffle restricts the movement of the reinforcement plate. Then, the reinforcement plate is rotated so that the through hole on the reinforcement plate is aligned with the threaded hole on the side wall of the second rod body, and then fixed with bolts to reinforce the stability of the overall structure of the rod body.

[0003] The above technical solution adjusts the overall length of the honing rod by arranging the first adjusting column and the second adjusting column in the threaded hole to adapt to honing holes of different depths. However, the above technical solution still has certain defects. For example, the above device adjusts the overall length of the honing rod by arranging the first adjusting column and the second adjusting column in the threaded hole. However, when adjusting, tools are needed for disassembly and adjustment, which is relatively complex in operation, increases the workload of the staff, and reduces the adjustment efficiency of the honing rod.

[0030] Please refer to Figures 1-4 , the present utility model provides a technical solution: an adjustable honing rod, including a honing rod 1;

[0031] An adjusting device is provided on the honing rod 1;

[0032] The adjusting device includes a sliding rod 6, two protective shells 9 and two pull rods 5. Pull rod grooves 4 are formed on the outer walls of the two protective shells 9. The outer walls of the two pull rods 5 are respectively slidably connected to the interiors of the corresponding pull rod grooves 4. The two protective shells 9 are fixedly connected to the outer wall of the honing rod 1. A sliding rod groove 14 is formed on the outer wall of one end of the honing rod 1. The outer wall of the sliding rod 6 is slidably connected to the interior of the sliding rod groove 14. Two second limiting block grooves 13 are formed on the inner wall of the sliding rod groove 14. Limiting blocks 15 are respectively slidably connected to the interiors of the two second limiting block grooves 13. A plurality of first limiting block grooves 8 are formed on the outer wall of the sliding rod 6. One ends of the two limiting blocks 15 close to the first limiting block grooves 8 are respectively in contact with the inner walls of the corresponding first limiting block grooves 8. Reset spring grooves 12 are formed inside the two protective shells 9. The interiors of the two reset spring grooves 12 communicate with the interiors of the corresponding pull rod grooves 4 respectively. The interiors of the two second limiting block grooves 13 communicate with the interiors of the corresponding reset spring grooves 12 respectively. One ends of the two pull rods 5 close to the limiting blocks 15 slide and extend into the interiors of the second limiting block grooves 13 and are respectively fixedly connected to the outer walls of one ends of the corresponding limiting blocks 15. Two reset springs 16 are respectively arranged inside the two reset spring grooves 12. Both ends of the four reset springs 16 are fixedly connected to the outer wall of one end of the corresponding limiting block 15 and the inner wall of the protective shell 9 respectively.

[0033] Wherein, a connecting head 7 is fixedly connected to one end of the sliding rod 6 away from the honing rod 1. A connecting rod 3 is fixedly connected to one end of the honing rod 1 away from the connecting head 7. A threaded rod groove 10 is formed on the outer wall of one end of the connecting rod 3 away from the honing rod 1. A honing head 2 is arranged outside the honing rod 1. A threaded rod 11 is fixedly connected to the outer wall of one end of the honing head 2. The outer wall of the threaded rod 11 is threadedly connected to the inner wall of the threaded rod groove 10.

[0034] Furthermore, when using this device, it is started by connecting to an external power supply. First, the honing rod 1 is installed on an external device through the connector 7. Then, the external device drives the honing head 2 for use. When it is necessary to adjust the length of the honing rod 1, pulling the pull rod 5 to move in the opposite direction drives the limit block 15 to move in the opposite direction while driving the return spring 16 to contract. Then, due to the opposite movement of the limit block 15, its outer wall is disengaged from the inside of the first limit block groove 8. Furthermore, pulling the honing rod 1 downward can pull out the sliding rod 6 from the inside of the honing rod 1. Then, after adjusting to the required length, release the pull rod 5. The force generated by the return spring 16 on the pull rod 5 causes the limit block 15 to reset while driving the pull rod 5 to reset. Then, when it is necessary to remove the honing head 2, use a tool to unscrew the honing head 2 to disassemble it for maintenance and repair.

[0035] By adjusting the device, pulling the pull rod 5 to move in the opposite direction drives the limit block 15 to move in the opposite direction while driving the return spring 16 to contract. Then, due to the opposite movement of the limit block 15, its outer wall is disengaged from the inside of the first limit block groove 8. Furthermore, pulling the honing rod 1 downward can pull out the sliding rod 6 from the inside of the honing rod 1. Then, adjust to the required length, which facilitates the adjustment of the length of the honing rod 1, reduces the difficulty of adjustment, and at the same time avoids the need for staff to use tools for adjustment, effectively reducing the workload of the staff. The honing head 2 is internally threaded with the threaded rod groove 10 opened on the lower connecting rod 3 of the honing rod 1 through the threaded rod 11. This increases the stability during work, and at the same time, the honing head 2 can be unscrewed with a tool for maintenance and repair, effectively improving the maintenance and repair efficiency of the honing head 2.

[0036] Working principle: First, the honing rod 1 is installed on an external device through the connector 7. Then, the external device drives the honing head 2 for use. When it is necessary to adjust the length of the honing rod 1, pulling the pull rod 5 to move in the opposite direction drives the limit block 15 to move in the opposite direction while driving the return spring 16 to contract. Then, due to the opposite movement of the limit block 15, its outer wall is disengaged from the inside of the first limit block groove 8. Furthermore, pulling the honing rod 1 downward can pull out the sliding rod 6 from the inside of the honing rod 1. Then, after adjusting to the required length, release the pull rod 5. The force generated by the return spring 16 on the pull rod 5 causes the limit block 15 to reset while driving the pull rod 5 to reset. Then, when it is necessary to remove the honing head 2, use a tool to unscrew the honing head 2 to disassemble it for maintenance and repair.

[0037] The above has described the embodiments of the present invention in detail with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art in the technical field, various changes can be made without departing from the purpose of the present invention.
