Description

Technical Field

[0001] The utility model relates to the technical field of cold-drawn tube polishing processing, in particular to a cold-drawn tube fluid polishing device. Background Art

[0002] Many precision parts are difficult to polish manually, such as complex internal holes, cross holes, micropores, and curved holes. Manual polishing is inefficient and difficult. Fluid polishing is a machining method that uses a high-speed flow of polishing fluid to remove tiny burrs and unevenness on the workpiece surface. During the polishing process, the high-speed flow of polishing fluid rubs against the workpiece surface, removing surface material and improving the surface finish.

[0003] In the production of cold-drawn tubes, the inner and outer walls of the cold-drawn tubes are easily scratched by the workpiece, and the scratches are long and shallow. If traditional grinders are used for grinding, the grinding time is long and the grinding and polishing are unstable. Existing fluid polishing equipment can only polish the inner wall of the cold-drawn tube by passing fluid into it, and cannot achieve double-sided polishing, resulting in low polishing efficiency.

[0004] Therefore, it is necessary to provide a new cold-drawn tube fluid polishing equipment to solve the above technical problems. Utility Model Content

[0048] When in use, after the inner support tube 5 adapted to the cold-drawn tube is fixed to the liquid inlet end plate 4 by means of the sealing screw 41, the servo motor 23 is started to drive the screw 22 to rotate, thereby driving the transmission plate 31 to slide in the vertical groove 201, thereby driving the slip ring 32 to slide along the support rod 21 until the roller 34 slides into the tube of the inner support tube 5, and the roller 34 is used to support the end of the inner support tube 5 away from the liquid inlet end plate 4, and the movement is carried out until the pressure plate 35 is completely squeezed on one end of the inner support tube 5 to achieve support and pressure fixation, and then the cold-drawn tube and the outer cover tube 7 are clamped in the slot 1 601 and the slot 2 602 of the limit plate 6, and then the limit plate 6 is twisted to press the outer cover tube 7 and one end of the cold-drawn tube to be processed and pressed on the liquid inlet end plate 4. The cover tube 7 is then fixed using the sealing screw 41 corresponding to the liquid inlet end plate 4, and then the whole is inserted into the inner support tube 5. When inserting, the support bolt 51 is driven to drive the ball head 511 to lift the end of the cold-drawn tube close to the liquid inlet end plate 4, so that the inner and outer walls of the cold-drawn tube are formed into a circulation channel using the liquid inlet end plate 4, the inner support tube 5, the limit plate 6 and the outer cover tube 7. Then, the circulation pump 8 is started to introduce the liquid into the vertical hole 401 through the liquid inlet ring 81, and then the liquid is continuously introduced into the circulation channel through the horizontal hole 402 aligned with the circulation channel, and then discharged from the guide groove 1 603 and the guide groove 2 604 to the water tank 9, realizing circulating liquid supply and circulation polishing, thereby realizing double-sided fluid polishing operation.
