Adjustable-template angle control device for line heating plates

The utility model discloses an adjustable-template angle control device for line heating plates. The adjustable-template angle control device is formed by a triangular body which comprises a first edge, a second edge and a third edge, the first edge is used for being movably connected with an adjustable template, a second edge is used for being connected with a curved outer plate, the third edge forms the triangular body with the first edge and the second edge, the first edge is hinged with the second edge and the third edge respectively, the second edge is provided with a second guide rail and a second connecting block used for being connected with the third edge, and one end of the second connecting block is hinged with the third edge while the other end is slidably connected on the second guide rail. The triangular body is capable of being connectedly fixed with the curved outer plate with the inner angle being adjusted flexibly, angle fixation between the adjustable template and the curved outer plate during machining of the linear curved outer plate of a ship is effectively assisted, the adjustable plate can be fixed at the corresponding place and is effectively prevented from being damaged, and machining accuracy and quality of the curved outer plate are improved.
