Description

Technical Field

[0001] This utility model relates to the field of rotary table technology, and in particular to a rotary table for a CNC gear hobbing machine. Background Technology

[0002] A CNC gear shaper is a specialized machine tool that uses CNC technology to automate gear processing. The maximum processing diameter of some CNC gear shapers is limited by the diameter of the rotary table, while the gear processing diameter of some machines exceeds the range of the rotary table diameter. To meet production requirements, it would be difficult to purchase more gear shapers with larger processing ranges. An existing patent discloses a "rotary table for a CNC gear shaper". This solution uses workpiece support blocks evenly distributed on the rotary table body. After the workpiece is placed on the workpiece support block, the workpiece is aligned and clamped by moving the workpiece support block. The slide table slides on the support block through a slide rail, and at the same time, the screw is rotated to move the workpiece support block on the support block, thereby moving the workpiece support block. The position of the workpiece support block can be adjusted, and the diameter of the rotary table body is increased, thus expanding the processing diameter of the original machine tool.

[0003] However, this solution requires workers to rotate the screws sequentially to adjust the workpiece support blocks, which wastes a lot of time and affects work efficiency. Therefore, a rotary table for CNC gear hobbing machines is proposed. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a rotary table for a CNC gear hobbing machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a rotary table for a CNC gear hobbing machine, comprising a rotary table body, four sliding grooves on the upper surface of the rotary table body, a sliding column slidably connected in each sliding groove, a connecting column fixedly connected to the upper surface of each sliding column, a slide table fixedly connected to the upper surface of every two connecting columns, and a base fixedly connected to the bottom of the rotary table body, the base having a rotating structure.

[0006] As a further description of the above technical solution:

[0007] The rotating structure includes a rotating column that is rotatably connected to the upper surface of the rotary table body. One end of the rotating column extends to the inside of the base and is fixedly connected to a worm gear.

[0008] As a further description of the above technical solution:

[0009] A rotating disk is fixedly connected to the upper surface of the rotating column. The upper surface of the rotating disk has four arc-shaped grooves, and each arc-shaped groove is slidably connected to a corresponding connecting column.

[0010] As a further description of the above technical solution:

[0011] A rotating rod is rotatably connected through one side of the base, and a knob is fixedly connected to one end of the rotating rod.

[0012] As a further description of the above technical solution:

[0013] The other end of the rotating rod is fixedly connected to a worm gear, which meshes with a worm wheel.

[0014] As a further description of the above technical solution:

[0015] The upper surface of the base has multiple drainage holes, and the bottom of the base has four liquid outlets.

[0016] As a further description of the above technical solution:

[0017] Each slide is fixedly connected to a workpiece support block on its upper surface. Each workpiece support block has a clamping groove on its upper surface. Anti-slip teeth are fixedly connected to the opposite side inside each clamping groove.

[0018] This utility model has the following beneficial effects:

[0019] Compared with existing technologies, this CNC gear shaping machine uses a rotary table. By incorporating a rotating rod, knob, worm gear, worm wheel, rotating column, rotating disk, and arc-shaped groove, rotating the knob drives the rotating rod, which in turn drives the worm gear, which in turn drives the rotating column, which in turn drives the rotating disk. The rotating disk, through the arc-shaped groove, moves the corresponding connecting column, which in turn moves the corresponding sliding column and slide table, which in turn moves the corresponding workpiece support block. This expands the processing diameter of the original machining bed, eliminating the need for operators to manually rotate screws for adjustment, thus saving time and improving work efficiency.

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.

[0032] Reference Figures 1 to 9This utility model provides a rotary table for a CNC gear hobbing machine: it includes a rotary table body 1, the upper surface of the rotary table body 1 is provided with four sliding grooves 2, each sliding groove 2 is slidably connected with a sliding column 3, the upper surface of each sliding column 3 is fixedly connected with a connecting column 4, the upper surfaces of every two connecting columns 4 are jointly fixedly connected with a slide table 5, the upper surface of each slide table 5 is fixedly connected with a workpiece support block 6, the upper surface of each workpiece support block 6 is provided with a clamping groove, and the opposite side of each clamping groove is fixedly connected with an anti-slip tooth 7. The bottom of the rotary table body 1 is fixedly connected with a base 8, the upper surface of the base 8 is provided with multiple drain holes 10, and the bottom of the base 8 is provided with four liquid outlets 11. When the coolant leaks into the sliding groove 2 through the arc groove 907, it drips through the multiple drain holes 10 and then flows out through the four liquid outlets 11. The base 8 is provided with a rotating structure 9.

[0033] To achieve the goal of increasing the machining diameter of the machining bed, the rotating structure 9 includes a rotating column 905 that is rotatably connected to the upper surface of the rotary table body 1.

The worm gear 903 meshes with the worm wheel 904. Rotating the knob 902 causes the rotating rod 901 to rotate, which in turn causes the worm gear 903 to rotate. The worm gear 903 then causes the worm wheel 904 to rotate, which in turn causes the rotating column 905 to rotate. The rotating column 905 then causes the rotating disk 906 to rotate. The rotating disk 906 moves the corresponding connecting column 4 through the arc groove 907. The connecting column 4 moves the corresponding sliding column 3 and slide table 5, which in turn moves the corresponding workpiece support block 6.

This eliminates the need for operators to rotate screws sequentially for adjustment, saving time and improving work efficiency.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
