[0001] This utility model relates to the field of sharpening devices, and in particular to a sharpening device for an arc-tooth milling cutter disc. Background Technology
[0002] The spiral bevel gear grinding device is a key piece of equipment used for grinding spiral bevel gear machining tools to ensure the geometric accuracy and cutting performance of the tools.
[0003] Sharpening devices typically use mechanical clamping structures to fix the workpiece, and then manually adjust the axial and radial positions of the milling cutter head to achieve sharpening alignment of cutting edges with different curvatures. Operators judge the relative position based on their own experience, and workers with different skill levels may cause large fluctuations in tool setting errors. Tool setting relies on manual experience, is prone to tool setting deviations, and the process is relatively cumbersome and inconvenient. Utility Model Content

[0007] The angle adjustment component two includes a U-shaped frame one rotatably mounted on the top of the translation plate. A drive motor is fixed to the end of the U-shaped frame one away from the translation plate, and a rotating disk is fixedly mounted on the drive end of the drive motor.
[0008] An angle adjustment component one is installed in the rear part of the middle of the machine compartment. A servo motor is fixed at the rotating end of the angle adjustment component one. A grinding disc is fixedly connected to the driving end of the servo motor. The angle adjustment component one includes a base and an L-shaped plate fixed on the top of the base. A rotating cavity is opened on the side of the horizontal end of the L-shaped plate near the grinding disc. A U-shaped frame two is rotatably installed inside the rotating cavity. An L-shaped frame is fixed in the inner cavity of the U-shaped frame two. A line laser pointer is inserted and installed at the protruding end of the L-shaped frame, which is located directly above the grinding disc.
[0009] As an improved technical solution, a linear motor for driving the translation plate to move is installed inside the cabin and below the translation plate, and the translation plate is fixed on the movable end of the linear motor.
[0010] As an improved technical solution, the workpiece mounting sleeve has a threaded hole at the center of the end away from the U-shaped frame, and a hexagonal bolt is threaded onto the workpiece mounting sleeve through the threaded hole, so that the workpiece is clamped between the workpiece mounting sleeve and the hexagonal bolt.
[0011] As an improved technical solution, the angle adjustment component 2 further includes two shaft brackets 1 fixed on the translation plate. A mounting shaft 1 is rotatably installed between the two shaft brackets 1. Gears 1 are sleeved at both ends of the mounting shaft 1 and located in the inner cavity of the U-shaped frame 1. A translation seat is slidably installed on the top of the translation plate and passing through the inner cavity of the U-shaped frame 1. A rack 1 that meshes with the gear 1 is installed at both support sides of the translation seat. An electric telescopic rod 1 is installed on the top of the translation plate and located between the two racks 1.
[0012] As an improved technical solution, the angle adjustment component one also includes two shaft brackets two mounted on the L-shaped plate. The shaft brackets two are rotatably mounted with mounting shafts two via bearings on them. The end of the mounting shaft two away from the servo motor is sleeved with a gear two. On the L-shaped plate and directly below the two gears two, racks two that mesh with the gears two are slidably mounted. An electric telescopic rod two is fixed in the middle of the inner cavity of the L-shaped plate and on the side away from the grinding disc. The movable end of the electric telescopic rod two is fixedly connected to a U-shaped connecting rod, and the two supports of the U-shaped connecting rod are respectively connected to the two racks two.
[0013] As an improved technical solution, angle indicating structure 1 is installed at both ends of the mounting shaft 1, and angle indicating structure 2 is installed at the opposite ends of the two racks 2, wherein the angle indicating structure 1 and the angle indicating structure 2 have the same structure.
[0014] As an improved technical solution, the angle indicating structure includes a linkage shaft and an angle disk. The linkage shaft is fixed on the mounting shaft and is in a coaxial setting state. One end of the linkage shaft is equipped with a pointer that indicates on the angle disk.

[0016] 1. In this utility model, the extension and retraction of the electric telescopic rod one drives the arc tooth milling cutter disc to adjust the longitudinal angle, which is used to adapt to different angles of arc teeth and different processing requirements. The extension and retraction of the electric telescopic rod two drives the rack two to move laterally. Under the meshing transmission of the rack two and the gear two, the U-shaped frame two is driven to rotate longitudinally through the mounting shaft two, which realizes the adjustment of the longitudinal angle of the grinding disc, further adapting to different angles of arc teeth and different processing requirements.
[0017] 2. In this utility model, when the longitudinal angle of the grinding disc and the arc-tooth milling cutter disc is adjusted, the linkage shaft and the pointer will be rotated simultaneously. The pointer indicates the angle on the angle disc, which is the current angle of the grinding disc or the arc-tooth milling cutter disc. The state of the adjusted angle can be understood in real time, which is more conducive to controlling the adjustment of the angle and improving the adjustment accuracy.
[0018] 3. In this utility model, the longitudinal angles of both the grinding disc and the arc-tooth milling cutter disc can be adjusted during tool setting, which is beneficial for adapting to different angles and different processing requirements. Furthermore, during tool setting, the linear laser pointer will emit a linear laser line, which is projected onto the cutting edge of the rack and the arc-tooth milling cutter disc. The position on the arc-tooth milling cutter disc is exactly the processing position of the grinding disc, which improves the accuracy of tool setting, helps to reduce tool setting deviation, and simplifies the tool setting process by assisting in the tool setting process, thus reducing the difficulty of tool setting.

[0032] Inside the machine compartment 1 and below the translation plate 6, there is a linear motor 7 for driving the translation plate 6 to translate, and the translation plate 6 is fixed on the movable end of the linear motor 7.
[0033] The workpiece mounting sleeve 4 has a threaded hole at the center of the end away from the U-shaped frame 53. A hexagonal bolt 41 is threadedly installed on the workpiece mounting sleeve 4 through the threaded hole. The workpiece is clamped between the workpiece mounting sleeve 4 and the hexagonal bolt 41.

The arc-tooth milling cutter disc is pressed and fixed on the workpiece mounting sleeve 4 by the hexagonal bolt 41.
[0043] The procedure for adjusting the angle of the arc tooth milling cutter head is as follows:
[0044] The extension and retraction of the electric telescopic rod 55 drives the rack 52 to move laterally. Under the meshing transmission of the rack 52 and the gear 54, the mounting shaft 56 is driven to rotate clockwise or counterclockwise, which drives the arc tooth milling cutter disc to adjust the longitudinal angle.
[0045] The adjustment procedure for the angle of the grinding disc 2 is as follows:
