Description

Technical Field

[0001] This utility model relates to the field of honing rod technology, and in particular to a honing rod structure with multi-stage stroke limit protection. Background Technology

[0002] Honing is a high-precision hole-making process widely used in industries such as automotive, aerospace, and machinery manufacturing. The honing rod, as the core component of honing, directly affects machining accuracy and equipment lifespan through its performance and stability.

[0003] To facilitate honing of workpieces with different inner diameters using a honing rod, the length of the honing rod needs to be adjusted to match the depth of the workpiece's inner diameter. However, most existing honing rod length adjustments lack a stroke limit protection structure, leading to problems such as the honing rod being adjusted too long or too short. This can easily cause impacts to both ends of the inner cavity of the outer sleeve of the honing rod, potentially damaging the sleeve over time and causing inconvenience in the use of the device.

[0004] Therefore, it is necessary to propose a honing rod structure with multi-stage stroke limit protection to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a honing rod structure with multi-stage stroke limit protection, so as to solve the problem mentioned in the background art that most existing honing rods lack stroke limit protection structures when adjusting the length of the honing rod, resulting in the honing rod being adjusted too long or too short, which can easily cause impact to both ends of the inner cavity of the outer sleeve of the honing rod, and eventually damage to the sleeve.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a honing rod structure with multi-stage stroke limit protection, including a sleeve, wherein an adjusting rod is slidably connected inside the sleeve;

[0007] The end of the adjusting rod that extends into the sleeve is provided with a travel limit protection component;

[0008] The travel limit protection component includes an adjusting block, a limit rod, a spring, a protective sleeve, and a rubber pad;

[0009] The adjusting block is slidably connected to the outside of the limiting rod, and the side of the adjusting block is fixedly connected to one end of the spring. The other end of the spring is fixedly connected to one side of the protective sleeve, and the other side of the protective sleeve is fixedly connected to the side of the rubber pad.

[0010] Preferably, one end of the adjusting rod that extends movably into the sleeve is fixedly connected to the side of the adjusting block, and the outside of the adjusting block is slidably connected to the inside of the sleeve.

[0011] Preferably, the inside of the protective sleeve is slidably connected to the outside of the adjusting rod.

[0012] Preferably, both ends of the limiting rod are fixedly connected to the side of the inner cavity of the sleeve, and the outside of the limiting rod is slidably connected to the inside of the spring.

[0013] Preferably, both the sleeve and the adjusting rod have an adjusting hole inside, and a fixing bolt is inserted into the adjusting hole. The fixing bolt passes through and extends to the outside of the sleeve, and a nut is connected to the external thread of the fixing bolt.

[0014] Preferably, a connecting rod is fixedly connected to the end of the adjusting rod away from the sleeve, a connecting bolt is inserted inside the connecting rod, an installation rod is inserted outside the connecting bolt, a honing sleeve is fixedly connected to one end of the installation rod, and a honing strip is provided on the outside of the honing sleeve.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] By setting up a travel limit protection component, the spring and rubber pad can effectively absorb the impact force when adjusting the length of the adjusting rod. This prevents the adjusting rod from being adjusted too long or too short, which could easily cause impacts to both ends of the inner cavity of the outer sleeve of the adjusting rod and damage the sleeve over time. This improves the protection of the sleeve. Furthermore, the limit rod can disperse the torque generated when the adjusting rod rotates due to honing, preventing excessive torque on the fixing bolt when the adjusting rod rotates, which could damage the adjusting hole and affect the adjustment of the adjusting rod length. This brings convenience to the use of the device. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides, for example Figures 1-4 The honing rod structure shown includes a sleeve 1, with an adjusting rod 2 slidably connected inside the sleeve 1. A stroke limit protection component is provided at one end of the adjusting rod 2 that extends movably into the sleeve 1. The stroke limit protection component includes an adjusting block 3, a limiting rod 4, a spring 5, a protective sleeve 6, and a rubber pad 7. The stroke limit protection component can be used to limit the movement of the sleeve 1, improving its protective performance.

[0024] The adjusting block 3 is slidably connected to the outside of the limiting rod 4, and the side of the adjusting block 3 is fixedly connected to one end of the spring 5. The other end of the spring 5 is fixedly connected to one side of the protective sleeve 6, and the other side of the protective sleeve 6 is fixedly connected to the side of the rubber pad 7. The end of the adjusting rod 2 that extends into the sleeve 1 is fixedly connected to the side of the adjusting block 3, and the outside of the adjusting block 3 is slidably connected to the inside of the sleeve 1. The inside of the protective sleeve 6 is slidably connected to the outside of the adjusting rod 2. Both ends of the limiting rod 4 are fixedly connected to the side of the inner cavity of the sleeve 1, and the outside of the limiting rod 4 is slidably connected to the inside of the spring 5. When the length of the adjusting rod 2 is adjusted by pulling it (the length of the adjusting rod 2 can also be adjusted electrically by an electric push rod), the spring 5 and the rubber pad 7 can effectively absorb the impact force, avoiding the problem that the length of the adjusting rod 2 is too long or too short, which may cause the two ends of the inner cavity of the sleeve 1 to impact. Over time, this may cause damage to the sleeve 1, thus improving the protection of the sleeve 1.

[0025] In addition, both the sleeve 1 and the adjusting rod 2 have adjusting holes 8 inside. A fixing bolt 9 is inserted into the adjusting hole 8, and the fixing bolt 9 passes through and extends to the outside of the sleeve 1. A nut is threaded onto the outside of the fixing bolt 9. When it is necessary to adjust the length of the adjusting rod 2, the nut can be rotated in the opposite direction to separate the nut from the fixing bolt 9. Then, the fixing bolt 9 can be pulled out to separate it from the sleeve 1. Then, the adjusting rod 2 can be pulled out to select a suitable adjusting hole 8 to adjust the length of the adjusting rod 2. The limiting rod 4 can be used to disperse the torque generated when the adjusting rod 2 rotates due to honing, avoiding the problem that the fixing bolt 9 is subjected to excessive torque when the adjusting rod 2 rotates, which could damage the adjusting hole 8 and affect the length adjustment of the adjusting rod 2. This brings convenience to the use of the device.

[0026] Finally, a connecting rod 10 is fixedly connected to the end of the adjusting rod 2 away from the sleeve 1. A connecting bolt 11 is inserted into the inside of the connecting rod 10, and a mounting rod 12 is inserted into the outside of the connecting bolt 11. A honing sleeve 13 is fixedly connected to one end of the mounting rod 12, and a honing strip 14 is provided on the outside of the honing sleeve 13. The honing strip 14 can be used to hone the workpiece.

[0027] Working principle: When the length of the adjusting rod 2 needs to be adjusted, the nut can be rotated in the opposite direction to separate the nut from the fixing bolt 9. Then, the fixing bolt 9 can be pulled to separate it from the sleeve 1. Then, the adjusting rod 2 can be pulled to select the appropriate adjusting hole 8 to adjust the length of the adjusting rod 2. The limiting rod 4 can be used to disperse the torque generated when the adjusting rod 2 rotates due to honing, avoiding excessive torque on the fixing bolt 9 when the adjusting rod 2 rotates, which could damage the adjusting hole 8 and affect the length adjustment of the adjusting rod 2. This makes the use of the device more convenient. The spring 5 and rubber pad 7 can effectively absorb the impact force, preventing the adjusting rod 2 from being adjusted too long or too short, which could easily cause impact to both ends of the inner cavity of the outer sleeve 1 of the adjusting rod 2. Over time, this could easily damage the sleeve 1, thus improving the protection of the sleeve 1.
