Description

Technical Field

[0001] This utility model relates to the technical field of deburring equipment, specifically a spindle deburring machine for internal hole processing. Background Technology

[0002] Burrs on mechanical parts are caused by various factors, including plastic deformation during machining, flash from casting and forging, and weld residue. With increasing industrialization and automation, particularly in the aerospace and instrumentation sectors, the demand for precision in manufacturing mechanical parts and the miniaturization of mechanisms have made the harmfulness of burrs particularly apparent. This has led to widespread attention and research into the formation mechanism and removal methods of burrs. A spindle deburring machine is a device that uses cutting tools mounted on a high-speed rotating spindle to deburr internal holes.

[0003] Currently, spindle deburring machines used for internal hole machining generally employ a single spindle for deburring, resulting in low efficiency. Furthermore, if used for parts with a round hole on one side and a long hole on the other, the single spindle deburring machine requires two sets of programs. Therefore, two separate single spindle deburring machines are typically used for processing, leading to increased costs and reduced efficiency. Additionally, the debris generated during processing by existing spindle deburring machines is difficult to collect. Therefore, an improved technology is urgently needed to solve this problem in the existing technology. Utility Model Content

[0039] Working method and principle: First, the first motor 13 drives the rotating pressure column 8 to rotate, so that one of the planes of the rotating pressure column 8 faces downward, supporting the C-shaped strip workpiece on the double-control mold. At this time, the two holes on both sides of the C-shaped strip workpiece correspond to the two holes of the double-hole mold 5. The rear end of the C-shaped strip workpiece abuts against the limiting column 36 and is supported on the limiting block 37. The first motor 13 drives the rotating pressure column 8 to rotate again, so that the arc surface of the rotating pressure column 8 presses against the upper surface of the workpiece. Then, the second motor 14 drives the output shaft of the bidirectional output shaft reducer 9 to rotate, thereby causing the swing arm 10 to rotate 90°, and the pressure rod 11 installed on the swing arm 10 presses against the upper surface of the rotating pressure column 8, completing the positioning of the workpiece. The third motor 26, in conjunction with a lead screw pair, drives the left slide 15 to move. The upright 16 on the upper surface of the left slide 15, in conjunction with the fifth motor 28 and a lead screw pair, drives the left lifting seat 17 to rise and fall along the guide rail of the upright 16. The left transverse seat 18, in conjunction with the sixth motor 29, a toothed belt, a toothed pulley, and a lead screw pair, moves laterally along the guide rail of the left lifting seat 17, thereby enabling the left main shaft 19 to move closer to and away from the double-hole mold 5, and simultaneously enabling the lifting and translation of the left main shaft 19. The fourth motor 27, in conjunction with a lead screw pair, drives the right slide 21 to move. The right transverse seat 22, in conjunction with the eighth motor 32, a toothed belt, a toothed pulley, and a lead screw pair, moves laterally along the guide rail of the right slide 21, thereby enabling the right main shaft 23 to move closer to and away from the double-hole mold 5, and simultaneously enabling the translation of the right main shaft 23. The left spindle 19 drives the left tool 20 to rotate at high speed through the cooperation of the seventh motor 30, toothed belt, and toothed pulley. The right spindle 23 drives the right tool 24 to rotate at high speed through the cooperation of the ninth motor 33, toothed belt, and toothed pulley, thereby achieving deburring of the through holes on both sides of the C-shaped strip workpiece. This utility model has a reasonable structure. A mold table 3 is set in the middle of the upper surface of the worktable 1. A double-hole mold 5 is set on the upper surface of the mold table 3. The left spindle 19 and the right spindle 23 are movably set on both sides of the double-hole mold 5. The two spindles can simultaneously deburr two holes, greatly improving efficiency. Moreover, the left spindle 19 is three-axis movable, which can be used for structures with a strip-shaped waist hole on one side and a round hole on the other side, greatly improving the scope of application and flexibility. The double-hole mold 5 is set in the first receiving groove 4. The upper surface of the worktable 1 and the mold table 3 are both provided with second receiving grooves 25. The first receiving groove 4 and the second receiving groove 25 can collect the debris generated during deburring, greatly improving convenience.
