DETAILED DESCRIPTION
[0017] The technical scheme in the embodiments of the utility model will be clearly and completely described in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, not all the embodiments.
[0018] As Figures 1-2As shown, a multi-angle adjustable rolling cutter includes a tool holder 10 for connecting to a machine tool turret. An extension arm 11 is fixedly mounted on the tool holder 10, and a connecting plate 12 is fixedly mounted on the extension arm 11. An angle plate 20 is adjustablely connected to the connecting plate 12, and a tool shank 30 is connected to the angle plate 20. A rolling cutter 40 is connected to the front end of the tool shank 30. In use, the tool holder 10 is fixedly connected to the machine tool turret to perform wheel hub rolling operations. When changing the production wheel type and needing to adjust the angle between the cutter and the wheel hub surface, simply adjusting the angle plate 20 relative to the connecting plate 12 by the corresponding angle is sufficient to meet the rolling operation requirements of different wheel profiles. This eliminates the hassle of frequently changing the entire tool, saves changeover adjustment time, and ensures operational efficiency. Simultaneously, it eliminates the need to design and manufacture dedicated rolling cutters 40 for different wheel profiles, saving tool development costs and reducing the difficulty of storing and managing on-site tooling.
[0019] In a preferred embodiment, a spline groove 13 is provided on the end face of the connecting plate 12, and a spline 21 is provided on the angle plate 20 corresponding to the spline groove 13. The connecting plate 12 and the angle plate 20 are connected by the spline groove 13 and the spline 21 to improve the connection strength between the connecting plate 12 and the angle plate 20. When it is necessary to adjust the angle between the tool and the hub surface, the angle plate 20 is disassembled so that the spline 21 on the angle plate 20 is disengaged from the spline groove 13 of the connecting plate 12. After the angle plate 20 is rotated radially by a certain angle, the angle plate 20 is reconnected and fixed to the connecting plate 12 to complete the tool angle adjustment.
[0020] Furthermore, the tool holder 30 and the angle disk 20 are rotatably connected via a rotating shaft 31, further refining the angle adjustment accuracy. When the adjustment via the connecting plate 12 and the angle disk 20 cannot adequately match the tool machining angle or only a small angle adjustment is required, the tool angle can be adjusted by adjusting the rotation angle of the tool holder 30 relative to the angle disk 20, thereby improving the angle adjustment accuracy and facilitating small angle adjustment operations.
[0021] Preferably, a locking lug 22 is provided on the outer diameter of the angle plate 20, and an arc-shaped groove 23 is provided through the locking lug 22. A fastening screw 24 is provided on the tool bar 30 corresponding to the arc-shaped groove 23. The fastening screw 24 passes through the locking lug 22 and the arc-shaped groove 23 in sequence, and a nut 25 is screwed to the end of the fastening screw 24, so that the tool bar 30 can be locked at any angle position of the arc-shaped groove 23, and the tool angle can be finely adjusted.
[0022] Preferably, such as Figure 2 As shown, the angle disk 20 and the tool holder 30 have corresponding sawtooth grooves 26 on their contact end surfaces to increase the friction between them and ensure a reliable connection.
[0023] Preferably, the locking lug 22 is marked with an angle scale 27 as a reference for the angle adjustment of the cutter bar 30, facilitating the adjustment operation.
[0024] The above disclosed is only the specific embodiment of the present application, but the present application is not limited to this.
