A plurality of groups of clamping components 4 are installed on the upper and lower surfaces of the turning plate 2. The clamping component 4 includes a fixed clamping plate 45 and a movable clamping plate 43. A push plate 42 is installed on one side of the movable clamping plate 43. The push plate 42 is driven by a clamping cylinder 41 to perform telescopic movement. A fixed block 44 is installed on one side of the fixed clamping plate 45. A positioning seat 46 is installed at the bottom of the clamping cylinder 41. A guiding column 461 is installed on one side of the positioning seat 46. A guiding hole is provided on the push plate 42. The guiding column 461 is in sliding fit with the guiding hole. Through a clever structural design, the efficient and stable clamping function of the fixture is realized. The core of the fixture lies in its clamping component, which is composed of a fixed clamping plate and a movable clamping plate. The movable clamping plate is driven by a clamping cylinder to perform telescopic movement, so as to realize the flexible clamping of the workpiece. At the same time, the fixed clamping plate is installed on the turning plate through a fixed block, ensuring the stability of the clamping component. The positioning seat installed at the bottom of the clamping cylinder and the sliding fit between the guiding column and the guiding hole on the push plate further improve the stability and accuracy during the clamping process, ensuring that the fixture can maintain a high-precision and high-efficiency working state during rotation and clamping.

[0021] In this embodiment, four groups of clamping components 4 are installed on each of the front and back surfaces of the turning plate 2 to ensure the simultaneous clamping and fixing of multiple workpieces.

[0022] Specifically, both ends of the turning plate 2 are rotatably connected to the base 1. An electric motor 3 is installed outside one end of the base 1. The output shaft of the electric motor 3 is fixedly connected to the turning plate 2, and the turning plate 2 is driven by the electric motor to perform a 360-degree turning operation.

[0023] Furthermore, positioning grooves are provided on the surfaces of the fixed clamping plate 45 and the movable clamping plate 43 close to the workpiece. The shape of the mating groove is adapted to the shape of the workpiece surface, so as to ensure the stability of the clamped workpiece and prevent the workpiece from sliding.

[0024] Furthermore, the fixed clamping plate 45 is installed on the fixed block 44 through bolts, the fixed block 44 is fixed on the turning plate 2 through bolts, the clamping cylinder 41 is installed on the positioning seat 46 through bolts, and the positioning seat 46 is installed on the turning plate 2 through bolts, which facilitates the quick disassembly and assembly operations of the fixed clamping plate 45 and the clamping cylinder 41.

[0025] Furthermore, a bayonet socket 421 is provided on the surface of the push plate 42, and a bayonet joint 411 is installed on the output shaft of the clamping cylinder 41.

Then, the clamping cylinder 41 is started, and its output shaft drives the push plate 42 to perform telescopic movement, thereby driving the movable clamping plate 43 to move towards the fixed clamping plate 45 to achieve stable clamping of the workpiece.

[0028] During this process, the guide post 461 on the positioning seat 46 is in sliding fit with the guide hole on the push plate 42, ensuring the stability and precision during the clamping process. At the same time, the fixed clamping plate 45 is installed on the turning plate 2 through the fixing block 44, ensuring the stability of the clamping assembly.

[0029] When multi-sided machining of the workpiece is required, only the motor 3 needs to be started, and its output shaft drives the turning plate 2 to perform a 360-degree turning operation, so that the workpiece can be turned to the required machining position without readjusting the position of the fixture or the workpiece, greatly improving the machining efficiency and precision.

[0030] In addition, this fixture also has the characteristics of quick disassembly and assembly.
