[0019] This utility model provides a hob cutter holder 106 for a gear hobbing machine, including a frame 101 and a mounting assembly 102. The mounting assembly 102 includes a movable seat 103, a mounting seat 104, a rotating seat 105, a hob cutter 106, a driving component 107, a guide rod 112, and a sealing plate 113. The driving component 107 includes a cylinder 108, a driving plate 109, and a connecting plate 110. The rotating seat 105 has a limiting protrusion 114, and the hob cutter 106 has a limiting groove 115. The driving component 107 drives the two movable seats 103 to move, thereby driving the corresponding mounting seat 104 and rotating seat 105 to move, so that the two rotating seats 105 move closer or further apart, thereby facilitating the disassembly and replacement of the hob cutter 106. It can be understood that the above solution can be used to facilitate the replacement of the hob cutter 106, and can also be used to improve the stability of the hob cutter 106.

[0020] In this specific embodiment, the frame 101 is mounted on a gear hobbing machine (not shown in the figure). The gear hobbing machine drives the frame 101 to move, thereby adjusting the feed of the hob 106 in the horizontal direction. During operation, the rotational motion of the hob 106 and the feed motion of the frame 101 work together to gradually cut the tooth groove according to the tooth profile parameters of the gear, thereby achieving the purpose of processing the gear.

[0021] The movable seat 103 is slidably connected to the frame 101 and located inside the frame 101. The mounting seat 104 is fixedly connected to the movable seat 103 and located on one side of the movable seat 103. The rotating seat 105 is rotatably connected to the mounting seat 104 and located inside the mounting seat 104. The hobbing cutter 106 is connected to the rotating seat 105 and is disposed on the rotating seat 105. The driving member 107 is disposed on the frame 101 and is used to drive the movable seat 103 to move. Two movable seats 103, two mounting seats 104, and two rotating seats 105 are provided. The rotating seats 105 are respectively located on both sides of the hob 106. The rotating seat 105 is provided with a slot 111 on the side near the hob 106. The shape of the slot 111 matches the two ends of the hob 106. The driving member 107 can drive the two moving seats 103 to move closer or further apart. A drive motor is also installed on one of the mounting seats 104. The output end of the drive motor is connected to one of the rotating seats 105. The drive motor drives the rotating seat 105 to rotate, and the rotating seat 105 drives the hob 106 to rotate, thereby achieving the purpose of driving the hob 106 to rotate.

[0022] When the hob 106 needs to be replaced, the drive component 107 is activated to drive the two movable seats 103 away from each other. At this time, the two mounting seats 104 and the two rotating seats 105 move synchronously with the movable seats 103. The slots 111 on the two rotating seats 105 gradually disengage from the two ends of the hob 106. At this time, the hob 106 loses the limitation and fixation on both sides, and the operator can easily grasp the middle of the hob 106 and remove it without the need for special tools to pry or disassemble other fasteners. After the old hob 106 is removed, a new hob 106 is taken and its two ends are aligned with the slots 111 of the two rotating seats 105 respectively. Then, the drive component 107 is activated to move the two movable seats 103 towards each other. The mounting seats 104 and rotating seats 105 move closer to each other synchronously. The slots 111 gradually fit onto the ends of the hob 106, thereby quickly completing the replacement of the hob 106 and improving the equipment's tool changing efficiency.

[0023] Secondly, the cylinder 108 is connected to the frame 101 and located inside the frame 101; the drive plate 109 is disposed on the cylinder 108 and connected to the output end of the cylinder 108; the two ends of the connecting plate 110 are respectively rotatably connected to the drive plate 109 and the movable seat 103; the operation of the cylinder 108 drives the drive plate 109 to move, causing the drive plate 109 to drive the connecting plate 110 to move, and the connecting plate 110 drives the corresponding movable seat 103 to move, thereby achieving the purpose of driving the movable seat 103 to move.

[0024] Meanwhile, the guide rod 112 is fixedly connected to the frame 101 and slidably connected to the movable seat 103, and passes through the movable seat 103; there are two guide rods 112, which are respectively connected to the two movable seats 103. The guide rods 112 guide the movement of the movable seat 103, thereby improving the stability of the movable seat 103 when it moves.

[0025] In addition, the sealing plate 113 is fixedly connected to the movable seat 103 and is located on the side of the movable seat 103 near the mounting seat 104; the frame 101 is provided with a sliding groove that matches the moving trajectory of the movable seat 103. The sealing plate 113 seals the sliding groove to prevent iron filings, coolant, and external dust generated during processing from entering the interior of the frame 101 through the sliding groove.

[0026] Finally, the limiting protrusion 114 is disposed inside the rotating seat 105; the hob 106 has a limiting groove 115, which is disposed on the side of the hob 106 near the limiting protrusion 114, and the limiting groove 115 cooperates with the limiting protrusion 114; when the two rotating seats 105 approach each other and clamp the hob 106, the limiting protrusion 114 is embedded in the corresponding limiting groove 115 to prevent relative sliding between the two during transmission.

[0027] When using the hob cutter 106 holder of this utility model, when it is necessary to replace the hob 106 to process gears of different specifications, the cylinder 108 is activated to drive the drive plate 109 to move. The connecting plate 110 pulls the two moving seats 103 away from each other, causing the rotating seat 105 to separate from the hob 106. The limiting protrusion 114 disengages from the limiting groove 115. At this time, the slot 111 separates from the end of the hob 106, and the operator can directly remove the old hob 106. When installing a new hob 106, first align the two ends of the suitable hob 106 with the two rotating seats 105. The slot 111 is activated, and the drive component 107 is started. The cylinder 108 drives the drive plate 109 to move. The two moving seats 103 are brought closer to each other through the connecting plate 110. The mounting seat 104 and the rotating seat 105 move synchronously until the slot 111 of the rotating seat 105 fits onto the end of the hob 106, and the limiting protrusion 114 is embedded in the limiting groove 115 of the hob 106. This completes the installation and fixation of the hob 106, making it convenient to install and remove the hob 106, and thus convenient to replace the hob 106.

[0028] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
