Description

Technical Field

[0001] This utility model relates to the field of rotary clamping technology for CNC machining, specifically a rotary clamping device for CNC machining centers. Background Technology

[0002] As a core piece of equipment in modern manufacturing, machining centers integrate multiple processes such as milling, boring, drilling, and tapping, enabling efficient machining of complex parts. Their key features are automatic tool change systems and multi-axis linkage control, which can complete multiple processes in a single setup, significantly improving machining accuracy and efficiency. CNC technology gives the machine tool its "brain," and vertical machining centers improve rigidity by reducing the length of the bed, but require a rotary clamping device to achieve multi-angle machining.

[0003] According to the patent application disclosed on the Internet, a rotary clamping device for a CNC machining center (authorization announcement CN222114290U) is described as follows: "A rotary clamping device for a CNC machining center includes a worktable, a sliding groove is provided on the worktable, clamping blocks are symmetrically and movably arranged in the sliding groove, a moving link is rotatably arranged on one side of the clamping block, an arc-shaped link is rotatably connected to one side of the moving link, and the two arc-shaped links are rotatably connected by a hydraulic rod."

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] This utility model, during use, uses a rotating motor to drive a rotating gear, which in turn rotates the rotating ring, thus rotating the worktable and allowing for machining of the workpiece at different angles, improving the device's usability. However, in actual use, the device can only rotate the worktable vertically and cannot adjust the horizontal rotation angle in real time as needed. Consequently, it cannot better coordinate with the adjustment and machining of CNC machining centers, resulting in a narrow range of applications. Furthermore, the gears are exposed, making it easy for waste chips to get stuck in the gear gaps during CNC machining, thus affecting the device's rotation. Therefore, an improved rotary clamping device for CNC machining centers is needed. Utility Model Content

[0036] Example 2:

[0037] Based on the existing technology's requirement to fix the workpiece, please refer to... Figure 5Furthermore, in conjunction with Embodiment 1, the clamping mechanism 5 includes a connecting plate 51, which is fixedly connected to the inner side of the top of the rotary worktable 4. A servo motor 52 is fixedly connected to the back of the connecting plate 51. A trapezoidal bidirectional screw 53 is fixedly connected to the output end of the servo motor 52.

[0039] In actual operation, when the device is in use, the control method of this utility model is controlled by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail. The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The supply of power is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.

[0040] First, the servo motors 212, 221, and 52 used in this device are all equipped with self-locking devices. These devices utilize existing self-locking technologies, which will not be elaborated further. During operation, the workpiece is placed on the rotary table 4 via the clamping mechanism 5. The servo motor 52 is then activated, synchronously driving the trapezoidal bidirectional screw 53 to rotate. This rotation of the screw 53 simultaneously moves the two side clamping plates 54 along the guide of the adjusting column 56, causing the two side clamping pads 55 to gradually approach the workpiece, thus fixing the workpiece between the clamping pads 55 and achieving rapid fixation. Furthermore, during processing, when the required processing angle needs to be adjusted, the servo motor 212 is activated via the angle adjustment rotation mechanism 2. Servo motor 212 synchronously drives trapezoidal screw 213 to rotate, which in turn drives movable sleeve 214 to move. During the movement of movable sleeve 214, slider 215 is pushed to move. In turn, during the movement of slider 215, sliding frame 216 rotates around the connection point of connecting frame 3, which in turn drives rotary table 4 to rotate. This allows for real-time adjustment of the vertical angle of the worktable and workpiece. Simultaneously, by starting servo motor 221, gear 222 is driven to rotate, which in turn drives gear 223 to rotate. Gear 223 then drives rotary plate 224 to rotate, which rotates along the guide groove of ball 226 and guide ring 227. This allows for real-time and rapid adjustment of the horizontal rotation angle of the workpiece and rotary table 4.
