Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0023] This utility model provides, for example Figures 1-3 The gear machining auxiliary device shown includes a support platform 100, a positioning pin 102, and a driving component. A gear carrier plate 101 is movably mounted on the top of the support platform 100. A cylindrical through hole is provided in the middle of the gear carrier plate 101. The positioning pin 102 is located directly above the cylindrical through hole of the gear carrier plate 101. The diameter of the positioning pin 102 gradually increases from bottom to top. The driving component is mounted on the support platform 100 and drives the positioning pin 102 to move vertically along the cylindrical through hole. In actual use, the gear blank to be machined is simply placed on the gear carrier plate 101, and the gear blank is moved vertically along the cylindrical through hole. The mounting hole and the cylindrical through hole of the gear carrier plate 101 are in a connected state, so that when the positioning pin 102 descends, it can be inserted into the mounting hole of the gear blank. The positioning pin 102 is driven to move down by the driving component. The diameter of the outer wall of the positioning pin 102 gradually increases from bottom to top, which can adapt to the size of the mounting hole on the gear blank, thereby adjusting the gear blank to a concentric position with the gear carrier plate 101. Furthermore, the pressing of the positioning pin 102 is used to fix the gear blank at the top of the gear carrier plate 101. The entire positioning process is not affected by the length of the positioning pin 102, and it can adapt to a wider range of gear specifications.

[0024] The driving components include a gantry frame 103 and a lifting component 104. The gantry frame 103 is located above the support platform 100, and both sides of the gantry frame 103 bend downwards and extend to be fixed to the side walls of the support platform 100. The lifting component 104 is fixedly connected to the middle of the top of the gantry frame 103. The telescopic end of the lifting component 104 extends to the inner side of the gantry frame 103 and is fixed to the positioning column 102. The top of the positioning column 102 is fixedly connected to a first ball bearing 105. The inner ring of the first ball bearing 105 is fixedly connected to the bottom outer wall of the lifting component 104, so that the positioning column 102 can rotate radially at the bottom position of the lifting component 104. In the prior art, the lifting component 104 can be an electric push rod, hydraulic telescopic rod, or other electrical device that can drive the positioning column 102 to move vertically. The setting of the first ball bearing 105 allows the connection between the positioning column 102 and the bottom of the lifting component 104 to be rotatably connected, so that the positioning column 102 can rotate with the gear while pressing down on the gear.

[0025] Furthermore, the gear carrier plate 101 is T-shaped, wider at the top and narrower at the bottom. The bottom of the gear carrier plate 101 passes through a rotating hole in the middle of the bearing platform 100 and extends to the lower position. A second ball bearing 107 is fixedly connected between the gear carrier plate 101 and the rotating hole. An external gear ring 108 is fixedly sleeved on the bottom of the outer wall of the gear carrier plate 101. A drive gear 109 is meshed with the side wall of the external gear ring 108. The drive gear 109 is rotatably connected to the bottom end of the bearing platform 100. A concave base 106 is fixedly connected to the bottom end of the bearing platform 100. A servo motor 110 is fixedly connected to the inner wall of the concave base 106. The rotating end of the servo motor 110 is connected to the drive gear 109. A knob screw 111 is threaded into the bottom of the side wall of the gantry frame 103. One end of the knob screw 111 extends to the inside of the gantry frame 103 and is rotatably connected to an arc-shaped sleeve 112. The bottom end of the arc-shaped sleeve 112 is connected to the bearing... The top of the platform 100 is movably fitted, and a brake pad 113 is fixedly connected to one end of the arc-shaped sleeve 112 facing the gear carrier plate 101. After the gear is positioned on the gear carrier plate 101, when the position needs to be adjusted during processing, the servo motor 110 drives the drive gear 109 to rotate. With the meshing transmission between the drive gear 109 and the external gear ring 108, the gear carrier plate 101 is driven to rotate through the second ball bearing 107, thereby adjusting the processing position of the gear's outer tooth surface. In addition, the user can manually turn the knob screw 111 clockwise to move the arc-shaped sleeve 112 along the top of the platform 100 toward the side wall of the gear carrier plate 101. This causes the brake pad 113 to press against the side wall of the gear carrier plate 101, thereby locking the gear carrier plate 101 radially and making the gear positioning of the gear carrier plate 101 more stable.

[0026] 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. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
