Technical Field

[0001] The utility model relates to the technical field of numerically controlled gear hobbing machines, in particular to a high-speed horizontal numerically controlled gear hobbing machine. Background Art

[0002] Gear hobbing machines are divided into two categories according to their layout: vertical and horizontal. Large and medium-sized gear hobbing machines are mostly vertical, while small gear hobbing machines and gear hobbing machines specially used for processing long shaft gears are all horizontal. Vertical gear hobbing machines are further divided into two types: worktable movement and column movement. When the vertical gear hobbing machine is working, the hob is mounted on the hob spindle and driven by the main motor to rotate. The tool holder can move vertically along the column guide rail and can also be adjusted at an angle around the horizontal axis. The workpiece is mounted on the worktable and driven to rotate by the indexing worm gear pair, which together with the movement of the hob constitutes an unfolding motion.

[0003] Existing gear hobbing machines cut workpieces by rotating the teeth at a uniform speed during processing. For example, a new CNC gear hobbing machine disclosed in Chinese patent announcement number "CN215658230U" includes a mounting seat fixedly installed on one side of the top of the base, and a rotating motor fixedly installed inside the mounting seat, a wheel fixedly installed at the output end of the rotating motor, and a protective shell fixedly installed on the top of the base.

[0004] During the processing of the current CNC gear hobbing machine, the mandrel rotates at high speed. At the same time, due to the rotation direction of the mandrel and its relative position to the rear column, the iron chips cut from the gear will splash everywhere under the action of centrifugal force. Although the existing gear hobbing machine is equipped with a protective door to protect personnel, the chips will still splash inside the equipment during processing. The splashed chips are not only scattered inside the equipment and difficult to clean, but also easily affect the equipment in the splashing direction. Utility Model Content

[0020] In this embodiment, the protective mechanism 6 includes a semicircular sleeve 61 and a protective shell 62. The protective shell 62 is semicircular and can be retracted into the semicircular sleeve 61. The protective shell 62 is movably connected to the inside of the semicircular sleeve 61. A toggle block 63 is fixed on the top of the protective shell 62. The protruding toggle block 63 can facilitate the staff to rotate the protective shell 62. A through groove 64 is opened on one side of the protective shell 62. The through groove 64 can contact the workpiece with the edge processing part for processing. A clamping mechanism 8 is provided between the semicircular sleeve 61 and the protective shell 62.

[0021] Furthermore, the clamping mechanism 8 includes a fixed box 81, which is fixed to one side of the semicircular sleeve 61. A clamping column 82 is slidably connected to the inside of the fixed box 81. A movable block 83 is fixed to the surface of the clamping column 82. The movable block 83 is slidably connected to the inside of the fixed box 81. A first spring 84 is sleeved on the surface of the clamping column 82 and the two ends of the first spring 84 are respectively in contact with the fixed box 81 and the movable block 83. Through holes 85 are provided on both sides of the protective shell 62. The through holes 85 are located on both sides of the protective shell 62 and have the same height as the clamping column 82. The clamping column 82 is movably connected to the through hole 85, and the clamping column 82 and the through hole 85 can be fixed after the protective shell 62 is contracted or expanded.

[0022] Furthermore, an arc groove 9 is provided on the top of the semicircular sleeve 61, the width of the arc groove 9 is greater than the diameter of the toggle block 63, and the toggle block 63 is movably connected to the arc groove 9. The arc groove 9 can cooperate with the toggle block 63 to limit the position to prevent the protective shell 62 from completely falling out.

[0023] In addition, the mounting mechanism 7 includes an annular groove 71 and a mounting ring 72. The annular groove 71 and the mounting ring 72 are clearance-fitted. The annular groove 71 is opened at the top of the rotating seat 5. The mounting ring 72 is fixed to the bottom of the semicircular sleeve 61. A mounting notch 73 is opened on one side of the mounting ring 72. The mounting notch 73 can conveniently pass through the processing component on the rotating seat 5. A clamping component 10 is provided between the mounting ring 72 and the annular groove 71.

[0024] It should be noted that the clamping assembly 10 includes a fixed frame 101 and a clamping block 102. A limiting groove corresponding to the clamping block 102 is provided on the top of the mounting ring 72. The fixed frame 101 is fixed to the top of the rotating seat 5. The clamping block 102 is slidably connected to the inner side of the fixed frame 101. A second spring 103 is fixed to one side of the clamping block 102 and the other end of the second spring 103 is fixedly connected to the fixed frame 101.

Both sides of the fixed frame 101 are provided with guide grooves 105 and are slidably connected to the protrusions 104. The clamping block 102 can slide inside the fixed frame 101 and squeeze the second spring 103. The mounting ring 72 can be clamped and fixed by the clamping block 102.

[0025] Working method: When performing gear hobbing, the staff needs to fix the workpiece on the mounting assembly on the top of the rotating seat 5, and then pull the clamping column 82 by hand and squeeze the first spring 84. When the clamping column 82 is disengaged from the through hole 85, the toggle block 63 can be pinched by hand to pull the protective shell 62 out of the semicircular sleeve 61. After the protective shell 62 is completely attached to the other side, the clamping column 82 can be clamped on the through hole 85 on the other side. At this time, the staff can start the equipment for processing, and the equipment can contact the workpiece through the through groove 64. When disassembling and assembling the protective assembly, the clamping block 102 can be pushed outward at the same time. The clamping block 102 squeezes the second spring 103 and disengages from the mounting ring 72 to remove the entire protective assembly.
