Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing and automated processing technology, specifically a shell cleaning tool for a side deep groove structure. Background Technology

[0002] In fields such as machining and casting, components with deep side groove structures, such as aerospace parts, automotive parts, and industrial valves, are widely used.

[0003] For deep groove structures, manual cleaning with small tools such as scrapers and brushes is difficult to precisely control the force and depth, which can easily lead to incomplete cleaning or damage to the workpiece surface. This is especially true for complex curved blind hole-type deep grooves. Traditional mechanical cutting fixtures are mostly fixed structures, and the size and angle of the cutting head are difficult to adjust flexibly, making them unsuitable for different specifications of side deep grooves. Some cleaning fixtures that rely on high-pressure water and ultrasonic technologies can improve efficiency, but they have high requirements for the material and structure of the workpiece. For example, high-pressure water jets may cause impact deformation to thin-walled parts, and ultrasonic cleaning has limited effectiveness in peeling off stubborn shells. In addition, traditional fixtures lack an adaptive feedback mechanism, making it difficult to adjust parameters in real time during the cleaning process, which poses a risk of damaging the workpiece.

[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] Example

[0024] Please see Figure 1-5 This utility model provides a technical solution: a shell cleaning tool for a side-deep groove structure, comprising:

[0025] The rod body 1 has a cleaning device 2 slidably connected to its top end. The cleaning device 2 scrapes and cleans the deep groove structure by rotating. The top end of the cleaning device 2 is rotatably connected to an auxiliary device 3. The auxiliary device 3 cleans by utilizing the rotation of the cleaning device 2. The rod body 1 is fixed to the lathe spindle by a lathe fixture. After the lathe is started, the spindle drives the rod body 1 to rotate, which in turn drives the cleaning device 2 and the auxiliary device 3 to rotate synchronously on the inner wall of the deep groove structure.

[0026] The cleaning device 2 includes a cutter head 20, with a bolt 21 threadedly connected to the inner wall of the cutter head 20. An auxiliary device 3 is slidably connected to the top of the cutter head 20. The outer wall of the cutter head 20 is slidably connected to the inner wall of the rod body 1. The outer wall of the bolt 21 is threadedly connected to the inner wall of the rod body 1. The outer wall of the cutter head 20 and the inner wall of the rod body 1 are slidably fitted together and fixed by the threaded connection of the bolt 21 to the rod body 1. The threaded connection of the bolt 21 can fix the axial position of the cutter head 20 to ensure stable scraping depth. When adjustment is required, the bolt 21 can be loosened to slide the cutter head 20 up and down to adapt to deep grooves of different depths. When the rod body 1 rotates, the cutter head 20 rotates synchronously with the rod body 1. Its outer cutting edge applies mechanical scraping force to the residual shell on the inner wall of the deep groove, peeling off the shell layer by layer.

[0027] The auxiliary device 3 includes a limiting cylinder 30, a handle 31 rotatably connected to the inner wall of the limiting cylinder 30, a rope winding shaft 32 fixedly connected to the outer wall of the handle 31, the outer wall of the limiting cylinder 30 fixedly connected to the outer wall of the rod 1, the inner wall of the limiting cylinder 30 rotatably connected to the outer wall of the rope winding shaft 32, and the rope winding shaft 32 is located on the inner wall of the limiting cylinder 30. The limiting cylinder 30 and the handle 31 are locked by a pin. Before the cleaning device 2 is removed from the inside of the deep groove structure, the handle is turned. During this process, the handle drives the rope winding shaft 32 to rotate on the inner wall of the limiting cylinder 30, so that the pull rope 33 and the rope winding shaft 32 are centered and continuously wrapped around the outer wall of the rope winding shaft 32. This drives the triangular scraper 34 to overcome the elastic force of the torsion spring 35 and continuously slide towards the inner wall of the blade head 20 and fit against the inner wall of the blade head 20. Then, the pin is inserted into the inner wall of the limiting cylinder 30 and the handle 31.

[0028] A pull rope 33 is wound around the outer wall of the rope-retracting shaft 32 through a through groove, which is located on the inner wall of the limiting cylinder 30. A triangular scraper 34 is fixedly connected to the end of the pull rope 33 away from the rope-retracting shaft 32. A torsion spring 35 is fixedly connected to the bottom end of the triangular scraper 34. A rotating rod 36 is fixedly connected to the inner wall of the triangular scraper 34. The outer wall of the pull rope 33 is slidably connected to the top end of the cutter head 20. The outer wall of the triangular scraper 34 is slidably connected to the inner wall of the cutter head 20, and the triangular part of the triangular scraper 34 is slidably connected to the inner wall of the deep groove structure. The end of the torsion spring 35 away from the triangular scraper 34 is fixedly connected to the inner wall of the cutter head 20. The end of the rotating rod away from the triangular scraper 34 is rotatably connected to the inner wall of the cutter head. The limiting cylinder 30 of the auxiliary device 3 is fixed to the outer wall of the rod body 1. When the cleaning device 2 is located inside the deep groove structure, the inner walls of the limiting cylinder 30 and the handle 31 are locked by a pin. When the pin is pulled out, the bottom end of the triangular scraper 34 is fixedly connected to the torsion spring 35. The elasticity of the torsion spring 35 causes the triangular scraper 34 to drive the rotating rod 36 to rotate on the inner wall of the cutter head 20 and quickly spring up. The triangular part of the triangular scraper 34 contacts the inner wall of the deep groove. When the cleaning device 2 rotates due to the rotation of the rod 1, the triangular scraper 34 generates a circumferential scraping force when it rotates with the cutter head 20, removing the debris that the cutter head 20 has not completely peeled off. When the inner wall of the deep groove is uneven, the triangular scraper 34 can rotate around the rotating rod 36 and automatically adapt to the inner wall contour through the elastic deformation of the torsion spring 35 to maintain a close fit.

[0029] When in use, the rod 1 is fixed to the lathe spindle by the lathe fixture. After the lathe is started, the spindle drives the rod 1 to rotate, which in turn drives the cleaning device 2 and the auxiliary device 3 to rotate synchronously on the inner wall of the deep groove structure.

[0030] First, the outer wall of the cutter head 20 slides against the inner wall of the rod body 1 and is fixed to the rod body 1 by a bolt 21 threaded connection. The threaded connection of the bolt 21 can fix the axial position of the cutter head 20 and ensure the stability of the scraping depth. When adjustment is needed, the bolt 21 can be loosened to allow the cutter head 20 to slide up and down to adapt to deep grooves of different depths. When the rod body 1 rotates, the cutter head 20 rotates synchronously with the rod body 1. Its outer cutting edge applies mechanical scraping force to the residual shell on the inner wall of the deep groove, peeling off the shell layer by layer.

[0031] The limiting cylinder 30 of the auxiliary device 3 is fixed to the outer wall of the rod body 1. When the cleaning device 2 is located inside the deep groove structure, the inner wall of the limiting cylinder 30 and the handle 31 is locked by a pin. When the pin is pulled out, the bottom end of the triangular scraper 34 is fixedly connected to the torsion spring 35. The elasticity of the torsion spring 35 causes the triangular scraper 34 to drive the rotating rod 36 to rotate on the inner wall of the cutter head 20 and quickly spring up. The triangular part of the triangular scraper 34 contacts the inner wall of the deep groove.

[0032] When the cleaning device 2 rotates due to the rotation of the rod 1, the triangular scraper 34 generates circumferential scraping force as the blade head 20 rotates, removing the debris that the blade head 20 has not completely peeled off. When the inner wall of the deep groove is uneven, the triangular scraper 34 can rotate around the rotating rod 36 and automatically adapt to the inner wall contour through the elastic deformation of the torsion spring 35 to maintain a close fit.

[0033] Before the cleaning device 2 is removed from the inside of the deep groove structure, the handle is turned. During this process, the handle drives the rope winding shaft 32 to rotate on the inner wall of the limiting cylinder 30, so that the pull rope 33 is centered on the rope winding shaft 32 and continuously wraps around the outer wall of the rope winding shaft 32. This causes the triangular scraper 34 to overcome the elastic force of the torsion spring 35 and continuously slide towards the inner wall of the blade head 20 and fit against the inner wall of the blade head 20. Then, the pin is inserted into the inner wall of the limiting cylinder 30 and the handle 31.
