[0019] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0020] Please see Figure 1-3This utility model provides a technical solution: a multi-station fixture for CNC machining of hardware parts, including a fixed plate 1, an electric push rod 7 and a threaded sleeve 11. The fixed plate 1 is provided with a mounting plate 2 and a movable plate 8; the mounting plate 2 is provided with a first fixture 4, and the movable plate 8 is provided with a second fixture 9. The electric push rod 7 is used to drive the movable plate 8 to move; the second fixture 9 is provided with a fixed threaded rod 10, and the fixed threaded rod 10 and the threaded sleeve 11 are used to connect the movable plate 8 and the second fixture 9.

[0021] Furthermore, a mounting plate 2 is fixedly installed on the top of the fixed plate 1. Positioning plates 3 are fixedly installed on the front side of the mounting plate 2 and the rear side of the movable plate 8. The first clamp 4 and the second clamp 9 are in contact with the positioning plates 3 but are not fixed. A positioning block 5 is fixedly installed on the bottom of the first clamp 4. An opening is provided on the top of the fixed plate 1 for the positioning block 5 to move. The positioning block 5 passes through the opening on the fixed plate 1 and extends to the bottom of the fixed plate 1. This arrangement allows the first clamp 4 to be installed on the fixed plate 1. The second clamp 9 can be connected to the movable plate 8 by fixing the threaded rod 10 and the threaded sleeve 11. In this way, if one set of the first clamp 4 or one set of the second clamp 9 is damaged, only one of them needs to be replaced, thereby reducing the cost of subsequent maintenance.

[0022] Furthermore, the movable plate 8 has a circular hole inside. A fixed threaded rod 10 is fixedly installed on the front side of the second clamp 9. One end of the fixed threaded rod 10 passes through the circular hole on the movable plate 8 and extends to the front side of the movable plate 8, where a threaded sleeve 11 is threadedly installed. A rotating washer 12 is rotatably installed on the rear side of the threaded sleeve 11. The rotating washer 12 has a hole inside that allows the fixed threaded rod 10 to move. The inner wall of the hole does not contact the outer wall of the fixed threaded rod 10. A handle is fixedly installed on the front side of the threaded sleeve 11. The top of the fixed plate 1... A fixed vertical plate 6 is fixedly installed on the part, and an electric push rod 7 is fixedly installed on the front side of the fixed vertical plate 6. The free end of the electric push rod 7 extends to the rear side of the fixed vertical plate 6 and is fixedly installed with the front side of the movable plate 8. A base plate 13 is fixedly installed at the bottom of the fixed plate 1. There are two sets of base plates 13. Anti-slip pads are attached to the bottom of both sets of base plates 13. This arrangement can clamp the hardware parts. In addition, the arrangement of multiple sets of first clamps 4 and second clamps 9 can clamp multiple sets of hardware parts, thereby increasing the clamping efficiency of the clamps.

[0023] Working principle: When in use, the positioning block 5 on the first clamp 4 is inserted into the opening on the fixed plate 1 to limit the first clamp 4. Then, the fixing threaded rod 10 on the second clamp 9 is passed through the circular hole on the moving plate 8, and the threaded sleeve 11 is threaded onto the fixing threaded rod 10, thereby fixing the second clamp 9 onto the moving plate 8. After placing the hardware between the first clamp 4 and the second clamp 9, the electric push rod 7 is started to drive the moving plate 8 to move. The movement of the moving plate 8 drives the movement of the second clamp 9, thereby clamping the hardware through the first clamp 4 and the second clamp 9.
