Description

Technical Field

[0001] This utility model relates to the field of gear processing technology, specifically to a high-precision gear hobbing machine. Background Technology

[0002] Gear hobbing machines are among the most widely used gear processing machine tools. They can cut spur gears, helical gears, worm gears, sprockets, etc. Patent CN220093276U discloses a high-precision gear hobbing machine, which includes a housing. The side wall of the housing is provided with a sliding groove. A water tank is fixedly connected to one side of the housing, and the side wall of the water tank is provided with a nozzle for spraying water to cool the gear during the gear cutting process. A second motor and a lead screw are provided in the sliding groove, and a support rod for assisting the gear cutting is provided on the lead screw. The bottom of the support rod is provided with a hobbing tool for cutting the gear.

[0003] The above patent utilizes a nozzle to dissipate heat and flush away debris during gear hobbing cutting. Water from a tank is continuously sprayed onto the gears and hobbing gears via the nozzle and pipes, preventing damage due to high temperatures during cutting. Furthermore, the position of the hobbing gears is flexibly adjusted via a sliding groove, an internal second motor, and a lead screw, improving the device's adaptability. However, when processing workpieces, the patent involves placing the workpiece on a cylindrical mounting rod. Since the rod's diameter is fixed, it can only limit and fix workpieces with specific inner diameters. When the workpiece is large, its inner diameter will vary. Placing a workpiece with a larger inner diameter on the mounting rod will cause it to wobble, leading to decreased machining accuracy during hobbing. This issue needs to be addressed.

[0004] Therefore, a high-precision gear hobbing machine is proposed. Utility Model Content

[0024] like Figures 1 to 4 As shown, a high-precision gear hobbing machine includes a base 1, a control box 2, and a housing 3. The control box 2 and housing 3 are both fixedly mounted on the top of the base 1. A filter plate 4 is provided on the housing 3. A drive assembly 5 for driving workpiece rotation is provided inside the housing 3 and on one outer wall. A fixing mechanism 6 for limiting and fixing workpieces of various inner diameters is provided on the surface of the drive assembly 5. A processing mechanism 7 for machining the workpiece is provided on the surface of the housing 3. A cooling assembly 8 for dissipating heat from the workpiece and the processing mechanism 7 is provided on the top of the base 1, the surface of the housing 3, and inside the housing 3. Specifically, the drive assembly 5... The start and stop of the machining mechanism 7 and the cooling assembly 8 are controlled by the control box 2. The workpiece is placed on the surface of the fixing mechanism 6, which fixes the workpiece to ensure the stability and accuracy of the workpiece during processing. The fixing mechanism 6 can adapt to workpieces with various inner diameters, thus expanding its application range. The workpiece on the fixing mechanism 6 is driven to rotate by the drive assembly 5, and the machining mechanism 7 processes the workpiece during the rotation process, thereby continuously cutting teeth on the workpiece. The cooling assembly 8 can cool and dissipate heat from the workpiece and the machining mechanism 7, thereby preventing damage to the workpiece and the machining mechanism 7 due to high temperature.

[0025] like Figure 2 , Figure 3As shown, the driving assembly 5 includes a first motor 501. The first motor 501 is fixedly mounted on one outer wall of the housing 3. A rotating shaft 502 is rotatably mounted on the surface of the housing 3. One end of the rotating shaft 502 is fixedly connected to the output end of the first motor 501, and the other end of the rotating shaft 502 passes through the surface of the housing 3 and extends into the interior of the housing 3. A turntable 503 is fixedly mounted on the end of the rotating shaft 502. The fixing mechanism 6 is disposed on the surface of the turntable 503. Specifically, when the first motor 501 is started, its output end drives the rotating shaft 502 to rotate, thereby causing the turntable 503 to rotate, which in turn causes the fixing mechanism 6 and the workpiece on its surface to rotate.

[0026] like Figure 3 , Figure 4As shown, the fixing mechanism 6 includes a slide groove 601. The surface of the turntable 503 has the slide groove 601. A lead screw 602 is rotatably mounted on the inner wall of the slide groove 601. One end of the lead screw 602 passes through the surface of the turntable 503 and extends to the outside of the slide groove 601. A first knob 603 is fixedly mounted on this end of the lead screw 602. A slider 604 is threadedly connected to the surface of the lead screw 602. The slider 604 is slidably mounted to the inner wall of the slide groove 601. A movable rod 605 is fixedly mounted on the surface of the slider 604. Both the slider 604 and the movable rod 605 are provided with... Two sets are provided. A fixing plate 606 is fixedly mounted on the surface of the movable rod 605. A slot 607 is formed on the surface of the movable rod 605. A threaded rod 608 is rotatably mounted on the inner wall of the slot 607. One end of the threaded rod 608 penetrates the surface of the movable rod 605 and extends to the outside of the slot 607. A second knob 613 is fixedly mounted on this end of the threaded rod 608. A movable plate 609 is threadedly connected to the surface of the threaded rod 608, and the movable plate 609 is slidably installed with the inner wall of the slot 607. A cavity 610 is formed on the surface of the movable plate 609. A spring 611 is fixedly installed inside the cavity 610. A limiting plate 612 is fixedly installed at one end of the spring 611, and the limiting plate 612 is adapted to the spring 611. Specifically, rotating the first knob 603 causes the lead screw 602 to rotate, thereby causing the two sets of sliders 604 to slide in opposite directions, thus adjusting the distance between the two sets of movable rods 605. After reducing the distance between the two sets of movable rods 605, the workpiece is placed on the two sets of movable rods 605 and the limiting plate 612 is pressed, so that the limiting plate 612 is embedded inside the cavity 610. When the limiting plate 612 is embedded inside the cavity 610... When the spring 611 is compressed, the workpiece is translated so that one side of the workpiece contacts the surface of the fixed plate 606. The second knob 613 is rotated according to the thickness of the workpiece, causing the threaded rod 608 to rotate, thereby causing the movable plate 609 to move horizontally, and then causing the surface of the movable plate 609 to contact the other side of the workpiece. The fixed plate 606 and the movable plate 609 clamp the workpiece. At this time, the first knob 603 is rotated in the opposite direction to widen the distance between the two sets of movable rods 605. When the surfaces of both sets of movable rods 605 are in contact with the inner wall of the workpiece, the workpiece is fixed.

[0027] like Figure 1 , Figure 2As shown, the processing mechanism 7 includes a support rod 701. The support rod 701 is slidably provided on one inner wall of the housing 3. An electric push rod 702 is fixedly provided on one side of the housing 3, and the telescopic end of the electric push rod 702 is fixedly connected to one side of the support rod 701. A second motor 703 is fixedly provided on the top of the support rod 701, and the output end of the second motor 703 passes through the surface of the support rod 701 and extends to its bottom. A hob 704 is fixedly connected to the output end of the second motor 703. Specifically, when the electric push rod 702 is activated, it drives the support rod 701 to move horizontally, thereby adjusting the distance between the hob 704 and the workpiece. When the hob 704 is adjusted to a suitable position, the second motor 703 drives the hob 704 to rotate. The relative rotational motion of the hob 704 and the workpiece simulates the meshing and rolling process of a pair of helical gears, thereby continuously cutting teeth on the workpiece.

[0028] like Figure 1 As shown, the cooling assembly 8 includes a coolant storage tank 801. The coolant storage tank 801 is fixedly mounted on the top of the base 1. The coolant storage tank 801 is equipped with a pump 802. A pipe 803 is fixedly inserted into the pump 802, and the other end of the pipe 803 penetrates the surface of the tank 3 and extends into the interior of the tank 3. A nozzle 804 is fixedly mounted on this end of the pipe 803, and the nozzle 804 corresponds to the hob 704. Specifically, the pump 802 draws the coolant from the coolant storage tank 801 into the interior of the pipe 803, and sprays the coolant onto the surface of the workpiece and the hob 704 through the nozzle 804, thereby cooling and dissipating heat from the workpiece and the hob 704.

[0029] like Figure 1 , Figure 2 As shown, the nozzle 804 is located on one side of the roller cutter 704, and the nozzle 804 and the roller cutter 704 are at the same horizontal height; specifically, when the nozzle 804 sprays coolant, it can spray coolant onto the surface of the roller cutter 704, thereby dissipating heat from the roller cutter 704 in a timely manner.

[0030] In summary: the drive assembly 5, the machining mechanism 7, and the cooling assembly 8 are all controlled by the control box 2 to start and stop. The workpiece is placed on the surface of the fixing mechanism 6, which fixes the workpiece, thereby ensuring the stability and accuracy of the workpiece during machining. The fixing mechanism 6 can adapt to workpieces with various inner diameters, thus expanding its applicability. The drive assembly 5 drives the workpiece on the fixing mechanism 6 to rotate, and the machining mechanism 7 processes the workpiece during the rotation process, thereby continuously cutting teeth on the workpiece. The cooling assembly 8 can cool and dissipate heat from the workpiece and the machining mechanism 7, thereby preventing damage to the workpiece and the machining mechanism 7 due to high temperature.
