A through-slot is formed around the groove, and a positioning plate is fitted inside each through-slot. A moving mechanism is provided around the outer surface of the clamping platform, each moving mechanism corresponding to one of the positioning plates. The moving mechanism allows the positioning plate to move within the through-slot and abut against the side wall of the workpiece inside the groove.

Sliding sleeves are fixedly connected to both sides of the positioning plate. The two sets of sliding sleeves are respectively sleeved on the outer surface of the two sets of connecting rods. Springs are sleeved on the surface of each connecting rod. An electromagnetic block is fixedly connected to the end of each set of connecting rods away from the clamping platform. The positioning plates are all magnetic.

[0007] Preferably, the electromagnetic block is energized to attract the positioning plate, and the spring is in a stretched state.

[0008] Preferably, the upper surface of the clamping platform is provided with fixing grooves on all four sides, and the fixing grooves and through grooves are provided in a one-to-one correspondence, and the corresponding fixing grooves and through grooves are connected. Fixing plates are installed inside the fixing grooves, and pressure plates are fixedly connected to the upper surface of the fixing plates.

[0016] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0017] This application discloses a machining fixture, including a clamping platform 1. The upper surface of the clamping platform 1 has an upward-opening groove 12 for placing a workpiece. The groove 12 has through slots 8 around its perimeter, and positioning plates 4 are installed inside each through slot 8. The outer surface of the clamping platform 1 is provided with a moving mechanism, which corresponds one-to-one with the positioning plates 4. The moving mechanism can move the positioning plates 4 inside the through slots 8 and make the positioning plates 4 abut against the side wall of the workpiece inside the groove 12.

[0018] In this embodiment, the workpiece to be processed is placed inside the groove 12, and then the moving mechanism drives the positioning plate 4 to abut against each side wall surface of the workpiece, so that the workpiece is automatically aligned and can be fixed.

[0019] Furthermore, each of the moving mechanisms includes two sets of connecting rods 10, one end of each set of connecting rods 10 is fixedly connected to the clamping platform 1, and the two sets of connecting rods 10 are located on both sides of the through groove 8. Sliding sleeves 11 are fixedly connected to both sides of the positioning plate 4. The two sets of sliding sleeves 11 are respectively sleeved on the outer surface of the two sets of connecting rods 10. Springs 9 are sleeved on the surface of each connecting rod 10. Electromagnetic blocks 5 are fixedly connected to the ends of the two sets of connecting rods 10 away from the clamping platform 1. The positioning plates 4 are all magnetic.

[0020] Furthermore, the electromagnetic block 5 is energized to attract the positioning plate 4, and the spring 9 is in a stretched state.

[0021] Furthermore, the upper surface of the clamping platform 1 is provided with fixing grooves 7 around the perimeter. The fixing grooves 7 and the through grooves 8 are provided in a one-to-one correspondence and are connected to each other. Fixing plates 6 are installed inside the fixing grooves 7. The upper surface of the fixing plates 6 is fixedly connected to the pressure plate 2. An electric push rod 3 is fixedly connected between the upper surface of the clamping platform 1 and the pressure plate 2.

[0022] Furthermore, the pressure plate 2 is a frame plate, and the shape of the pressure plate 2 is adapted to the opening of the clamping platform 1.

[0023] In this embodiment, in the initial state, the electromagnetic block 5 is energized to attract the positioning plate 4. The clamping end of the positioning plate 4 is located inside the through groove 8 so that the workpiece can be placed inside the groove 12. After the workpiece is placed, the electromagnetic block 5 is turned off, and the stretched spring 9 is reset, which drives the sliding sleeve 11 and the positioning plate 4 to move, so that the positioning plate 4 abuts against the side wall of the workpiece and pushes the workpiece to be aligned. Then, the electric push rod 3 is driven to move, which drives the pressure plate 2 and the fixing plate 6 to move down, so that the fixing plate 6 presses on the surface of the positioning plate 4 and fixes the positioning plate 4, thereby fixing the workpiece.

[0024] It should be noted that the switching interfaces of the electric push rod 3 and the electromagnetic block 5 are connected to an external power supply via wires. The circuits and related drivers involved are all existing conventional technologies, and will not be described in detail here.
