AI Technical Summary
In the prior art, the design of traditional honing tubes is complex and the existing sealing problems cause electroplating solutions to seep into the inner wall roughness of the honing tube, resulting in inconsistent inner wall roughness. In the prior art, the sealing of traditional honing tubes is prone to leakage of electroplating solutions, resulting in inconsistent inner wall roughness. The existing honing tube sealing leakage electroplating process is as follows: In the prior art, the sealing of traditional honing tubes is prone to leakage of electroplating solutions, and the existing honing tube sealing design is complex and prone to leakage of electroplating solutions, affecting the inner wall roughness.
A connecting rod is designed between plug a and plug b. Plug a has a sealing ring a, and plug b has a sealing ring b. Plug a has a recessed groove a on its lower outer wall and a socket a at its middle bottom. The upper cross-section is hexagonal. Plug b has a recessed groove b on its lower outer wall and a socket b at its middle bottom. The upper two sides are cut to form bosses. The outer wall of the honing tube opening on one side is recessed. 40Cr material is used for quenching to enhance hardness. The plug tooling design is ingenious to prevent electroplating chemicals from entering the inner wall of the honing tube.
It achieves high-performance sealing, prevents electroplating chemicals from entering the inner wall of the honing tube, ensures that the inner wall roughness meets the standard, reduces production costs and improves product quality.

TECHNICAL FIELD
[0001] The utility model relates to single cylinder damper field especially a honing pipe surface treatment plug structure. BACKGROUND
[0002] Traditional damper uses honing pipe, and the honing pipe is usually sealed by a plug, which has a complex design and sealing problems, and is easy to penetrate into electroplating liquid, resulting in the roughness of the inner wall. SUMMARY
[0003] In order to solve the above technical problems of complex design and easy penetration, the utility model provides a honing pipe surface treatment plug structure.
[0004] The technical scheme of the utility model is as follows:
[0005] A honing pipe surface treatment plug structure, comprising a honing pipe, the honing pipe is provided with a plug a and a plug b at both ends, a connecting rod is arranged between the plug a and the plug b, the plug a is designed to have a wire hole for hanging a fixture, a sealing ring a is arranged on the plug a, and a sealing ring b is arranged on the plug b.
[0006] The outer wall of the lower part of the plug a is provided with a recess groove a, the middle bottom is provided with a socket a, and the upper part is hexagonal in cross section.
[0007] The outer wall of the lower part of the plug b is provided with a recess groove b, the middle bottom is provided with a socket b, and the upper part is provided with a boss formed by cutting edges on both sides.
[0008] The outer wall of one side of the honing pipe is recessed.
[0009] The technical scheme of the utility model has the advantages of novel structure, ingenious and simple design, high-performance sealing ring design, prevention of electroplating liquid from entering the honing pipe inner wall and affecting the roughness of the inner wall, plug tooling made of 40Cr material for quenching to strengthen hardness and prevent durable deformation, inconsistent shapes of the plugs at both ends to prevent misassembly, no abnormality in surface treatment, up-to-standard inner wall roughness, and cost reduction and efficiency improvement. BRIEF DESCRIPTION OF DRAWINGS
[0010] Figure 1 It is a structural schematic view of the utility model;
[0011] Figure 2 , 3 It is a structural schematic view of the plug a of the utility model;
[0012] Figure 4 , 5 It is a structural schematic view of the plug b of the utility model. DETAILED DESCRIPTION
[0013] The utility model will be further described below in combination with the drawings and examples. EXAMPLE
[0014] As Figure 1 、 2 , 3, 4, 5 shows a honing tube surface treatment plug structure, including honing tube 1, the honing tube 1 both ends are provided with plug a4 and plug b7, the plug a4 and plug b7 between the connecting rod 2 is equipped, plug a4 design hanger wire hole.
[0015] The lower outer wall of the plug a4 is provided with recess groove a5, the middle bottom is provided with socket a, the upper cross section is hexagonal.
[0016] The lower outer wall of the plug b7 is provided with recess groove b8, the middle bottom is provided with socket b, the upper two sides are cut to form boss 9.
[0017] The outer wall of one side of the honing tube 1 is recessed.
[0018] In use, the honing tube raw material with the standard inner hole roughness is purchased, and the processing process is as follows: blanking, chamfering, turning outer diameter, turning outer teeth, turning spring groove; after numerical control processing, oil washing is carried out to prevent rust, special tooling is installed, plug a4 is sleeved into sealing ring a3, plug b7 is provided with sealing ring b6, the honing tube 1 is sealed and fixed by locking and locking, and then the surface treatment is carried out in the electroplating factory, after completion, the pipe body is wrapped with waste paper to prevent inner hole oxidation and rust, plug a4 is designed to hang the wire hole, which can be directly and well conducted without passing through the product itself, and the product surface is avoided to leave the abnormal influence of the appearance, such as the burn spot.
