[0020] 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.
[0021] As attached Figure 1 and Figure 2 As shown, this utility model provides a floating alignment gear hobbing device, including a workpiece limiting support 1 and a cutter 2 disposed on one side of the workpiece limiting support 1. The workpiece limiting support 1 includes a support component 11 and a workpiece limiting component 12. The workpiece limiting component 12 is located on one side of the support component 11 and is connected to the support component 11.
[0022] It should be noted that the cutter 2 is connected to the lifting assembly (such as a cylinder), which can drive the cutter 2 to move up and down to process the workpiece. The workpiece is usually a ring, so it has an inner diameter and an outer diameter.
[0023] As attached Figure 3 and Figure 4 As shown, the workpiece limiting assembly 12 includes a placement plate 121, a protective shell 122, a turntable 124, a connecting plate 127, a slider 126, a servo motor 128, and a clamping post 129. The placement plate 121 is disposed on one side of the support assembly 11, and the protective shell 122 is disposed on the lower end face of the placement plate 121. The turntable 124 is rotatably connected to the lower end face of the placement plate 121. Multiple connecting plates 127 are provided, and multiple connecting plates 127 are rotatably connected to the lower end face of the turntable 124. The slider 126 is disposed on the upper end face of the connecting plate 127 away from the turntable 124. The servo motor 128 is disposed inside the protective shell 122, and the output end of the servo motor 128 is connected to the turntable 124. The clamping post 129 is disposed on the upper end face of the slider 126, and the lower end face of the clamping post 129 is at the same horizontal plane as the upper end face of the placement plate 121. The placement tray 121 has a groove 125, and the slider 126 on the connecting plate 127 is slidably connected to the groove 125 on the placement tray 121. The lower end face of the turntable 124 has a groove 123, and the turntable 124 is rotatably connected to the bottom end of the inner side of the groove 123. The depth of the groove 123 is equal to the thickness of the turntable 124. The cross-section of the slider 126 is cross-shaped, and the size and shape of the slider 126 are adapted to the groove 125.
[0024] The specific implementation method is as follows: When using this utility model, first place the workpiece on the upper surface of the placement tray 121, and then place the workpiece on multiple clamping posts 129. Then start the servo motor 128, which drives the turntable 124 to rotate. The turntable 124 drives one end of the connecting plate 127 to rotate in an arc. The rotation of one end of the connecting plate 127 drives the slider 126 connected to the other end of the connecting plate 127 to move towards the inner wall of the workpiece. The slider 126 drives the clamping posts 129 to move. When the multiple clamping posts 129 fix the position of the workpiece placed on the upper surface of the placement tray 121, the cutter 2 can be moved up and down to process the workpiece.
[0025] The workpiece limiting component 12 can be used to process workpieces with different inner diameters, thereby increasing the range of workpieces that the device can process. In addition, the multiple clamping posts 129 provide multiple position limiting points for the workpiece, which can improve the stability of the workpiece being positionally limited.
[0026] As attached Figure 5 As shown, the support assembly 11 includes a support base 111, a fixed horizontal plate 112 is provided on the upper end surface of the support base 111, and a protective shell 122 is provided at one end of the upper end surface of the fixed horizontal plate 112. A guide post 113 is provided on the upper end surface of the support base 111, and a clamping plate 114 is provided above the support base 111. The clamping plate 114 is sleeved on the guide post 113, a limit block is provided at the top of the guide post 113, and a plurality of positioning screws 115 are provided on the upper end surface of the clamping plate 114.
[0027] The specific implementation method is as follows: when it is necessary to adjust the processing position of the workpiece, loosen the positioning screw 115, then adjust the position of the fixed horizontal plate 112 between the support base 111 and the clamping plate 114, and finally fix the position of the clamping plate 114 again by the positioning screw 115.
[0028] The support component 11 not only supports the workpiece but also allows for adjustment of its processing position.
[0029] Working principle of this utility model:
[0030] First, place the workpiece on the upper surface of the placement tray 121. The workpiece is then fitted onto multiple clamping posts 129. Then, start the servo motor 128, which drives the turntable 124 to rotate. The turntable 124 causes one end of the connecting plate 127 to rotate in an arc. The rotation of one end of the connecting plate 127 causes the slider 126 connected to the other end of the connecting plate 127 to move towards the inner wall of the workpiece. The slider 126 drives the clamping posts 129 to move. When the multiple clamping posts 129 have fixedly restricted the position of the workpiece placed on the upper surface of the placement tray 121, the cutter 2 can be moved up and down to process the workpiece. When it is necessary to adjust the processing position of the workpiece, loosen the positioning screw 115, then adjust the position of the fixed horizontal plate 112 between the support base 111 and the clamping plate 114. Finally, fix the position of the clamping plate 114 again using the positioning screw 115.
[0031] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
