[0004] The technical solution of this utility model is as follows:

[0005] A fixture for stamping irregularly shaped plates includes a base and further includes...

[0006] A mounting bracket is provided on the base and has two mounting walls that are mirror images of each other. The mounting walls are provided with mounting posts for placing the flange of the workpiece, and the mounting posts are provided with positioning pins that pass through the circular holes of the workpiece.

[0007] A connecting rod, comprising a connector detachably connected to the locating pin, the connector pressing against the upper end face of the flange of the workpiece;

[0008] A fixing rod is provided on the base;

[0009] A screw is used to install the connecting rod and the fixing rod together.

[0010] The fixing rod includes a frame, a washer, and a nut. The washer is disposed on the frame, the nut cooperates with the screw, and the bottom of the nut contacts the washer.

[0011] The mounting wall is provided with a hinge seat, and the fixing rod is hinged to the hinge seat.

[0012] It also includes a handle, the middle end of the fixed rod is hinged to the hinge seat, and the tail end is hinged to the handle; the hinge seat is provided with a rotatably connected locking plate, the middle end of the locking plate is hinged to the handle, and when the handle is rotated to the horizontal position, the locking plate contacts the tail end of the fixed rod to prevent the fixed rod from rotating clockwise.

[0013] The edge of the gasket is provided with a folded edge, which contacts the outer walls of both sides of the frame.

[0014] The beneficial effects of this utility model are: This utility model provides a fixed fixture for stamping irregularly shaped plates. The structure allows for convenient clamping, and the upper surface of the workpiece is basically unobstructed, which is very beneficial for assembly and processing. Attached Figure Description

[0015] Figure 1 This is a perspective view of one embodiment of the present utility model.

[0016] Figure 2 for Figure 1 Enlarged schematic diagram of point A in the middle.

[0017] Figure 3 This is a schematic diagram of a partial cross-section. Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings: As shown in the figures, a fixing fixture for stamping irregularly shaped plates includes a base 1 and a mounting bracket 2 disposed on the base. The bracket has two mutually mirror-arranged mounting walls 21, and mounting posts 22 for placing the flange of a workpiece 9 are provided on the mounting walls. The mounting posts are provided with positioning pins 221 that pass through the circular holes of the workpiece. A connecting rod 3 includes a connector 31 detachably connected to the positioning pins, and the connector presses against the upper end face of the flange of the workpiece. A fixing rod 4 is disposed on the base. A screw 5 is used to install the connecting rod and the fixing rod together. During installation, the workpiece is first placed on the mounting posts, with the positioning pins passing through the circular holes of the workpiece. Then, the fixing rod is placed on the upper end face of the workpiece, and the screw is tightened to achieve fixation.

[0019] In this embodiment, as shown in the figure, the fixing rod includes a frame 41, a washer 42, and a nut 43. The washer is disposed on the frame, and the nut cooperates with the screw, with the bottom of the nut contacting the washer. This makes the installation more stable.

[0020] In this embodiment, as shown in the figure, a hinge seat 25 is provided on the mounting wall, and the fixing rod is hinged to the hinge seat.

[0021] In this embodiment, as shown in the figure, a handle 26 is also included. The middle end of the fixed rod is hinged to the hinge seat, and the tail end is hinged to the handle. The hinge seat is provided with a rotatably connected locking plate 27. The middle end of the locking plate is hinged to the handle. When the handle is rotated to the horizontal position, the locking plate contacts the tail end of the fixed rod to prevent the fixed rod from rotating clockwise. Figure 3 As shown, when the handle is turned to the end, the locking plate will be positioned opposite the fixing rod to prevent it from rotating instantaneously and thus lock it. This prevents the other end of the fixing rod from tilting up. When rotation is required, the handle can be turned to move the locking plate away and drive the fixing rod. The first rotating shaft 410 is the hinge shaft of the frame, and the second rotating shaft 270 is the rotating shaft of the locking plate.

[0022] In this embodiment, as shown in the figure, the edge of the gasket is provided with a folded edge 421, which contacts the outer walls of both sides of the frame. This prevents the gasket from rotating, facilitating reassembly.

[0023] In the description of this utility model, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.
