[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] The present utility model provides a rotatable workpiece clamping structure, as Figures 1 - 3 shown, which includes a base 1. A support plate 2 is installed on the top of the base 1. A flipping frame 3 is arranged on the upper part of the support plate 2. One end of the flipping frame 3 is installed on the support plate 2 through a bearing seat 22, and the other end of the flipping frame 3 is driven to rotate by a driving motor 4. Two sets of clamping stations are installed on the flipping frame 3. Each set of clamping stations includes a tightening cylinder 32 and a positioning seat 33. The tightening cylinder 32 and the positioning seat 33 jointly act to clamp and position the workpiece. This structure is mainly composed of key components such as a base, a support plate, a flipping frame, and a driving motor. One end of the flipping frame is stably installed on the support plate through a bearing seat, and the other end is connected to the driving motor, realizing the easy rotation of the flipping frame. This design enables the clamping structure to adapt to the requirements of different processing procedures, without the need to frequently re-clamp the workpiece, thereby reducing the labor intensity of operators and significantly improving production efficiency. At the same time, the two sets of clamping stations provided on the flipping frame, each equipped with a tightening cylinder and a positioning seat, jointly ensure the stable clamping and precise positioning of the workpiece during processing, effectively improving the processing quality and product accuracy.

[0022] In this embodiment, several motor positioning blocks 21 are installed on the outer side of the support plate 2 near the driving motor 4, which is convenient for positioning the base of the driving motor 4, thereby realizing the precise fixation of the motor.

[0023] Specifically, a first tightening rod 322 is installed on the output shaft of the tightening cylinder 32, and a second tightening rod 331 is installed on the outer wall of the positioning seat 33. The first tightening rod 322 and the second tightening rod 331 respectively abut against both sides of the workpiece to realize the tightening operation of the workpiece.

[0024] Furthermore, a positioning convex block 332 is installed on the outer side of the positioning seat 33, which is convenient for clamping at the bayonet of the workpiece, thereby facilitating the precise positioning of the clamping position of the workpiece.

[0025] Furthermore, several second mounting holes 333 are provided on the positioning seat 33, and several first mounting holes 323 are provided on the tightening cylinder 32, which is convenient for the installation and disassembly of the positioning seat 33 and the tightening cylinder 32.

[0026] Further, an installation plate 321 is provided at the bottom of the clamping cylinder 32. The installation plate 321 is fixedly welded to the flipping frame 3.

[0027] Further, an opening 31 is provided on the surface of the flipping frame 3 near the lower part of the workpiece, which facilitates the discharge of chips generated during processing.

[0028] When the rotatable workpiece clamping structure of the present utility model is in use, first during operation, the flipping frame 3 is driven to rotate by the driving motor 4, so that the clamping structure can meet the requirements of different processing procedures. The motor positioning block 21 installed on the outer side of the supporting plate 2 near the driving motor 4 ensures the precise positioning and fixation of the base of the driving motor 4, thereby ensuring the stability of the rotation of the flipping frame 3.

[0029] When clamping the workpiece, the workpiece is placed in the clamping station on the flipping frame 3. Each clamping station consists of a clamping cylinder 32 and a positioning seat 33. A first clamping rod 322 is installed on the output shaft of the clamping cylinder 32, and a second clamping rod 331 is installed on the outer wall of the positioning seat 33. The two work together to respectively press against both sides of the workpiece to achieve stable clamping of the workpiece. At the same time, the positioning convex block 332 installed on the outside of the positioning seat 33 can catch the bayonet on the workpiece to ensure the accurate positioning of the clamped workpiece.

[0030] During the processing, the clamping cylinder 32 and the positioning seat 33 work together to keep the workpiece stably clamped and accurately positioned during processing, effectively avoiding processing errors and improving processing quality and product accuracy. At the same time, the opening 31 provided on the surface of the flipping frame 3 near the lower part of the workpiece facilitates the timely discharge of chips generated during processing and keeps the processing environment clean.

[0031] When it is necessary to replace or maintain the clamping structure, the second installation hole 333 provided on the positioning seat 33 and the first installation hole 323 provided on the clamping cylinder 32 can be used to conveniently install and disassemble the positioning seat 33 and the clamping cylinder 32.
