DETAILED DESCRIPTION

The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

1-5, a fixed mechanical fixture for machining includes a mounting box 1, the upper end surface of the mounting box 1 is rotatably connected with a clamping assembly;

The clamping assembly includes a turntable 2 rotatably connected to the upper end surface of the installation box 1, and a plurality of groups of rotating grooves 4 are provided on the inner circumference of the turntable 2. The rotating grooves 4 are arc-shaped structures that diffuse from the inside to the outside. A fixed plate 3 is arranged above the turntable 2, and the fixed plate 3 is fixedly connected to the installation box 1 through a fixed structure. A sliding groove 6 that cooperates with the rotating groove 4 is provided inside the fixed plate 3, and a sliding block 5 is slidably connected to the inside of the sliding groove 6. The bottom of the sliding block 5 is slidably connected to the inside of the rotating groove 4, and the upper end surface of the sliding block 5 is fixedly connected to a fixed rod 7. The rotation of the turntable 2 drives the sliding block 5 to slide in the rotating groove 4, so that the sliding block 5 slides along the sliding groove 6, so that the clamping rod 8 clamps the workpiece, and the clamping rod 8 in multiple directions can effectively clamp round or special-shaped workpieces.

A servo motor 13 is fixedly mounted inside the mounting box 1 via a motor frame. The output shaft of the servo motor 13 is drivingly connected to the turntable 2 , and the servo motor 13 can be driven to complete the clamping of the workpiece.

A limit slot 12 is provided inside the turntable 2, and a limit plate 11 is movably inserted inside the limit slot 12. The limit plate 11 is fixedly connected to the servo motor 13 by screws 14. The turntable can be disassembled and installed, which is convenient for maintenance and can increase the service life of the device.

The fixing structure includes fixing grooves 10 opened at the four corners of the installation box 1, and the outer end surface of the fixing plate 3 is fixedly connected with a fixing block 9, which is movably inserted into the inside of the fixing groove 10. The fixing block 9 is fixedly connected to the installation box 1 by bolts, so that the fixing plate 3 can be disassembled and installed, which is convenient for the maintenance of the device.

The outer end surfaces of the fixing rods 7 are sleeved with clamping rods 8, and the clamping rods 8 are fixedly connected to the fixing rods 7 by screws, so that the clamping rods 8 can be easily replaced, thereby increasing the application range of the device.

The clamping rod 8 is provided with different sizes, and different clamping rods 8 can be replaced according to workpieces with different requirements.

Working mode: When working, the turntable 2 is driven to rotate by the servo motor 13, thereby moving the sliding block 5 in the rotating groove 4, so that the sliding block 5 moves back and forth in the sliding groove 6. When multiple groups of clamping rods 8 move inward at the same time, the workpiece placed on the upper end surface of the fixed plate 3 is clamped. In this way, circular or special-shaped workpieces can be clamped. At the same time, when clamping a circular workpiece, the center of the circle can be ensured to be at the center of the circle of the fixed plate 3, which is convenient for processing the workpiece and increases the scope of use of the device. In the face of different workpieces, they can also be clamped by replacing the clamping rod 8. Because the turntable 2 and the fixed plate 3 are fixedly connected by screws 14, the structure is simple, convenient for disassembly and installation, and the device can be conveniently repaired and maintained, increasing the service life of the device.
