[0024] It should be noted that all directional indications in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0025] In this application, unless otherwise expressly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0026] In related technologies, when machining complex shells in a factory, the support surface needs to be completely covered on the fixture, which leads to the need to add a covered area before subsequent processing steps. At the same time, multiple clamping can cause the accumulation of processing errors.

[0027] To address some of the problems in the related technologies, this application provides a bending plate fixture. When needed, the workpiece to be processed is simply placed vertically with the processing surface exposed, and the workpiece is positioned from the edge by moving the clamping plate.

[0028] This application is described below with reference to the accompanying drawings and specific embodiments:

[0029] Combination Figures 1-4 This application provides a bending plate fixture, including a clamping plate 1. A base plate 2 perpendicular to the clamping plate 1 is fixedly installed at the bottom end of the clamping plate 1. A through groove 3 for placing the workpiece is opened in the middle of the clamping plate 1. A semi-through groove 4 for fixing the connecting end of the workpiece is opened on one side of the clamping plate 1 on the outer ring of the through groove 3. A sliding groove 5 is opened on the surface of the clamping plate 1 around the outer side of the semi-through groove 4. A locking bolt 6 is threadedly connected between the sliding groove 5 and the semi-through groove 4. A movable pressure plate 7 is slidably connected to the outer surface of the locking bolt 6. A positioning screw 8 is threadedly connected to the outer end of the movable pressure plate 7. The positioning screw 8 is slidably connected inside the sliding groove 5. A positioning pin 9 is inserted into the end of the movable pressure plate 7 away from the positioning screw 8. The positioning pin 9 is inserted into the connecting end of the workpiece.

[0030] In some embodiments, the surface of the clamping plate 1 is provided with a tool setting hole 10, which enables the determination of the machining reference.

[0031] Specifically, a compression spring 11 is sleeved on the outer surface of the locking bolt 6. The compression spring 11 is located between the clamping plate 1 and the movable pressure plate 7. This arrangement allows for better connection and positioning of the device via the movable pressure plate 7.

[0032] In some embodiments, the positioning pin 9 is divided into a round-headed positioning pin and a diamond-headed positioning pin. The surface of the semi-through groove 4 and the fixed end of the part are provided with positioning holes 12 that are adapted to the positioning pin 9.

[0033] Specifically, the cross-sectional shape of the sliding groove 5 is semi-circular, and the locking bolt 6 is located at the center point of the semi-circular sliding groove 5. This setting allows for fine adjustment of the position of the moving pressure plate 7.

[0034] Specifically, the clamping plate 1 and the base plate 2 are fixedly connected by a support beam 13. The cross-sectional shape of the support beam 13 is a right trapezoid. The two mutually perpendicular surfaces of the support beam 13 are parallel to and in contact with the clamping plate 1 and the base plate 2, respectively. This arrangement can ensure the stability of the device and at the same time limit the perpendicularity between the clamping plate 1 and the base plate 2.

[0035] In some embodiments, the surface of the movable pressure plate 7 has two symmetrical notches 14, and the locking bolt 6 is sleeved inside the two notches 14. The movable pressure plate 7 is inserted into the locking bolt 6. By setting the movable pressure plate 7 as an insertable type, the conversion efficiency can be improved.

[0036] The part is fitted into the through groove 3 and the fixed end of the part is located in the half through groove 4. By adjusting the movable pressure plate 7, the positioning pin can be aligned with the hole at the fixed end of the part and the part can be positioned by the positioning pin. The position can be fixed by rotating the locking bolt 6. The part can be vertically fixed on the surface of the clamping plate 1 by multiple movable pressure plates 7, so that the machined surface is exposed and kept in a vertical state for easy processing.
