[0042] This embodiment provides a workpiece processing device. The workpiece 10 includes an annular component 11 and a rod component 12. The annular component 11 is disposed at one end of the rod component 12. Figure 1 As shown, the processing device includes a base 100, a first base 110, a clamping mechanism 200, and a counterweight 300. The first base 110 is mounted on the base 100. The clamping mechanism 200 includes a chuck body 210, a gripper drive assembly, and a gripper assembly. The chuck body 210 is rotatably mounted on one end of the first base 110. Figures 2-3As shown, the gripper assembly includes three grippers 221, which are evenly distributed around the circumference of the chuck body 210. Each gripper 221 can slide radially along the chuck body 210. A counterweight 300 is provided on one of the three grippers 221. The gripper drive assembly is used to drive the three grippers 221 to jointly grip the annular part 11. The counterweight 300 and the rod 12 are radially opposite to each other along the annular part 11, which effectively realizes the mass balance compensation during the processing, reduces the vibration caused by eccentricity, and improves the stability of the gripping. In addition, the counterweight 300 counteracts the centrifugal force caused by the structural asymmetry of the workpiece 10, so that the chuck body 210 remains stable when rotating at high speed, avoiding vibration and jumping of the workpiece 10, which is conducive to improving the positioning accuracy and cutting accuracy of the processing process, and improving the processing quality of the workpiece 10.

[0043] Optionally, the counterweight 300 is fastened to the corresponding gripper 221 by the first fastener, which can ensure that the connection between the counterweight 300 and the gripper 221 is more stable, and make the installation and removal of the counterweight 300 more convenient. This allows users to quickly adjust or replace the counterweight 300 according to the mass distribution of different workpieces 10, thereby improving the adaptability of the workpiece processing device.

[0044] Optionally, the jaw 221 on which the counterweight 300 is mounted has a plurality of first threaded holes spaced radially along the chuck body 210. The counterweight 300 has a through hole, and the fastener can pass through the through hole and engage with any one of the threaded holes, thereby making the position of the counterweight 300 on the jaw 221 adjustable and reliably fixing the counterweight 300 on the jaw 221.

[0045] Optionally, the counterweight 300 can be a cylinder, cube, or cuboid. Different shapes of counterweight 300 can be flexibly selected according to the installation space of the gripper 221, thereby achieving more precise counterweight adjustment. In this embodiment, the counterweight 300 is preferably a cylinder.

[0046] Optionally, the counterweight 300 has a chamfered edge to prevent scratches to operators during installation and disassembly, thus improving operator safety.

[0047] Optionally, the gripper drive assembly includes a hydraulic cylinder and a transmission assembly. The hydraulic cylinder is connected to the input end of the transmission assembly, and the output end of the transmission assembly is connected to the three grippers 221. By driving the transmission assembly through the hydraulic cylinder, the three grippers 221 can be moved radially along the chuck body 210, thereby clamping and releasing the workpiece 10. The hydraulic cylinder can provide a more reliable clamping force, improving the reliability of clamping.

[0048] Optionally, the transmission assembly may include a pull rod, three first blocks, and three second blocks. The pull rod is slidably disposed within the chuck body 210 along the axial direction. The first end of the pull rod is connected to the piston rod of a hydraulic cylinder. The three first blocks are respectively engaged with the other end of the pull rod via a first wedge structure. The three second blocks are respectively slidably disposed on the chuck body 210 along the radial direction, and each second block is engaged with one of the first blocks via a second wedge structure. Each second block is equipped with a gripper 221. When the hydraulic cylinder drives the pull rod to move axially along the chuck body 210, the first and second wedge mechanisms drive the three second blocks to move radially along the chuck body 210, thereby achieving synchronous radial clamping or loosening of the three grippers 221. It should be noted that the first and second wedge structures are existing technologies and will not be described in detail.

[0049] In other embodiments, the transmission assembly may include a pull rod, three connecting rods, and three second blocks. The three second blocks are radially slidably disposed on the chuck body 210. Each second block is connected to the pull rod via a connecting rod, and each second block is equipped with a gripper 221. The pull rod is connected to the piston rod of a hydraulic cylinder, which can synchronously pull or push the three pull rods. The connecting rods convert the axial movement of the pull rods into the radial sliding of the second blocks, thereby realizing the synchronous radial clamping or releasing operation of the three grippers 221. This structure provides smooth transmission, uniform force distribution, and effectively improves the stability and response speed of the clamping mechanism 200.

[0050] Optionally, the workpiece processing device further includes a turret mechanism 400. The turret mechanism 400 includes a first moving component, a second base 410, a second moving component, a mounting arm 420, a turret assembly 430, and a second drive motor. The first moving component is disposed on the base 100, and the second base 410 is disposed on the moving end of the first moving component. The first moving component drives the second base 410 to move axially along the chuck body 210. One end of the second base 410 is inclinedly provided with a mounting arm 420, and the mounting arm 420 is provided with a second moving component. The turret assembly 430 includes a turret disk 431 and multiple machining tools 432. The turret disk 431 is rotatably mounted on the moving end of the second moving assembly. The multiple machining tools 432 are evenly distributed around the circumference of the turret disk 431, with at least a portion of each machining tool 432 protruding from the turret disk 431. The output end of a second drive motor is connected to the turret disk 431 for transmission. The second drive motor is used to drive the turret disk 431 to rotate by a preset angle, thereby performing the tool changing step. By setting the first moving assembly and the second moving assembly, the turret mechanism 400 achieves bidirectional adjustable movement of the turret assembly 430 in the axial direction of the chuck body 210 and the length direction of the mounting arm 420, enabling the machining tools 432 to accurately machine the workpiece 10.

[0051] Optionally, such as Figure 4 As shown, the turret assembly 430 includes a rotatable turret disk 431 and multiple circumferentially distributed machining tools 432. The turret disk 431 is controlled to rotate at a preset angle by a second drive motor, enabling rapid switching between multiple tool positions and improving machining efficiency and automation. Furthermore, the tilted design of the mounting arm 420 helps to expand the tool's range of motion, optimize the relative positional relationship between the tool and the workpiece 10, and further improve machining flexibility and accuracy.

[0052] Optionally, the first moving assembly includes a first lead screw, a first nut, and a third drive motor. The first lead screw is rotatably mounted on the base 100, the first nut is threadedly connected to the first lead screw, and the second base 410 is fixed to the first nut. The third drive motor is connected to the first lead screw for driving the first lead screw to rotate, thereby causing the first nut to move along the lead screw axis. This, in turn, drives the second base 410 to move precisely along the axial direction of the chuck body 210, ensuring that the turret assembly 430 on the second base 410 accurately processes the workpiece 10. It should be noted that the second moving assembly has the same structure as the first moving assembly, and the structure of the second moving assembly will not be described in detail.

[0053] Optionally, the turret mechanism 400 also includes a guide assembly, which includes a slide rail and a slider. One of the slide rail and the slider is disposed on the base 100, and the other of the slide rail and the slider is disposed on the second base 410. The slide rail and the slider slide in cooperation, which can improve the stability of the movement of the second base 410, thereby further improving the machining accuracy of the turret mechanism 400.

[0054] Optionally, the workpiece processing device also includes a protective cover mounted on the base 100. The clamping mechanism 200 and the turret mechanism 400 are both located inside the protective cover, effectively preventing the splashing of chips, coolant, and other debris, improving the cleanliness of the operating environment, and enhancing operator safety. The protective cover also reduces operating noise and improves operator comfort.

[0055] Optionally, the workpiece processing device further includes a loading and unloading mechanism 500, which includes a conveying component and two clamping components. Both clamping components are disposed on the moving end of the conveying component. One of the two clamping components is used to clamp the unprocessed workpiece 10, and the other of the two clamping components is used to clamp the processed workpiece 10.

[0056] The working process of the loading and unloading mechanism 500 is roughly as follows: when the first unprocessed workpiece 10 is clamped onto the clamping mechanism 200, the workpiece 10 begins to enter the processing flow; while the first workpiece 10 is being processed, the conveying component drives the two clamping components to move together to the picking area, and one of the two clamping components picks up the second unprocessed workpiece 10 and moves it to the waiting area to wait.

[0057] After the first workpiece 10 is processed, the conveying component synchronously drives the two clamping components to move to the clamping mechanism 200. One of the two clamping components unloads the processed workpiece 10, while the other clamps the second unprocessed workpiece 10 onto the clamping mechanism 200 for processing. Next, the conveying component moves the two clamping components to the finished product area, releasing the processed workpiece 10. Simultaneously, the other clamping component retrieves the third unprocessed workpiece 10 from the material handling area and moves it to the waiting area. This cycle repeats continuously, achieving seamless connection between loading and unloading actions, improving the continuity and automation level of equipment operation, significantly increasing loading and unloading efficiency, effectively shortening equipment standby time, and thus improving overall processing cycle time and capacity.

[0058] Optionally, the handling component can be a three-axis robot, a four-axis robot, a five-axis robot, a six-axis robot, etc. The structure of the above-mentioned multi-axis robot is prior art known to those skilled in the art, and will not be described in detail here.

[0059] Optionally, the clamping assembly includes a clamping cylinder and two clamping members, both of which are connected to the output end of the clamping cylinder. The clamping cylinder can drive the two clamping members to move closer or further apart, thereby clamping or releasing the workpiece 10. This clamping assembly has a fast response speed, runs smoothly, and is noiseless, which can significantly improve the efficiency and continuity of the loading and unloading process.

[0060] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model.
