It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.
[0028] like Figure 1 and Figure 2 As shown, a secondary arm fixture for picking up and placing ball valves includes a picking worktable 1 and a resetting worktable 2. The picking worktable 1 is located at one end of the surface of the resetting worktable 2. The picking worktable 1 has several gripper holes 3, each gripper hole 3 is equipped with a gripper cylinder 4, and each gripper cylinder 4 is equipped with several pneumatic grippers 5. The bottom of the resetting worktable 2 is equipped with several resetting rods 6, each resetting rod 6 is equipped with a resetting ring 7, and the resetting ring 7 is equipped with a drive mechanism for driving the resetting ring 7 to move. The surface of the resetting worktable 2 is equipped with a flipping mounting assembly, which is equipped with a flipping component for flipping the picking worktable 1 and the resetting worktable 2, and the flipping component is equipped with a drive component 8 for driving the fixture as a whole to move up and down.
[0029] The drive unit 8 is a robotic arm. During use, the gripper cylinder 4 controls the pneumatic gripper 5 to grasp or release the ball valve, completing the material handling of the ball valve. The reset rod 6 provides corresponding support for the reset ring 7. The reset ring 7 is displaced by the drive mechanism, so that the fixed ring 29 in the prior art can be reset accordingly, which is convenient for the next processing. The fixed ring 29 plays a role in fixing the ball valve. The flipping mounting assembly provides corresponding support for the flipping assembly. The flipping assembly can realize the conversion between the material handling worktable 1 and the reset worktable 2, so that two functions can be realized on one drive unit 8, which improves the operating efficiency.
[0030] like Figure 1 and Figure 2As shown, a reinforcing plate 9 is bolted to both sides of the material picking workbench 1. The bottoms of the two reinforcing plates 9 are bolted to both sides of the reset workbench 2. The reinforcing plate 9 has a triangular structure. Triangles have good stability, so that there are multiple support points between the material picking workbench 1 and the reset workbench 2. The material picking workbench 1 and the reset workbench 2 will not fall off or shift, thus improving the overall stability.
[0031] like Figure 1 and Figure 2 As shown, each pneumatic gripper 5 has a mounting plate 10 bolted to its bottom, and the mounting plate 10 is set on the surface of the gripper cylinder 4. There are three pneumatic grippers 5 in total. Through the mounting plate 10, the pneumatic grippers 5 can be stably installed on the gripper cylinder 4 to achieve flexible gripping of the ball valve.
[0032] like Figure 1 and Figure 2 As shown, the drive mechanism includes a drive plate 11, the bottom of which is bolted to several reset rings 7, and a drive cylinder 12 is provided on its top. The output shaft of the drive cylinder 12 passes through the drive plate 11. Two guide rods 13 are provided on the top of the drive plate 11, and the two guide rods 13 pass through the reset worktable 2 and are symmetrically distributed along the center of the drive plate 11.
[0033] The specific number of reset rings 7 is four, distributed along the four corners of the bottom of the reset worktable 2. The guide rod 13 is a movable guide rod, which is fixed to the reset worktable 2 by bolts through the guide rod sleeve, so as to realize synchronous displacement with the piston rod of the drive cylinder 12. The guide rod sleeve is fitted on the guide rod 13, and the bottom of the guide rod 13 is fixedly connected to the drive plate 11. The output shaft of the drive cylinder 12 enables the reset rings 7 to move, so that the fixed ring 29 in the prior art can be reset accordingly. The guide rod 13 can improve the overall stability of the drive mechanism during displacement, so that the drive plate 11 will not shake or deviate.
[0034] like Figure 1 and Figure 2 As shown, a mounting groove 14 is provided on the outer circumference of the reset rod 6, and a limiting plate 15 is provided on the mounting groove 14. The limiting plate 15 is bolted to the inner wall of the reset rod 6. A limiting hole 16 is provided on the circumference of the reset ring 7, and the limiting hole 16 cooperates with the limiting plate 15.
[0035] The limiting plate 15 is fixed with bolts, so that the limiting plate 15 can be stably installed on the inner wall of the support rod. The limiting hole 16 and the limiting ring cooperate to limit the reset ring 7. The limiting plate 15 extends along the axial direction of the reset rod 6, limiting the movement range of the reset ring 7, so that the limiting ring 7 will not fall off during use.
[0036] like Figure 3 and Figure 4As shown, the flip installation assembly includes a flip support rod 17, a flip base plate 18, and a flip positioning plate 19. There are four flip support rods 17, which are symmetrically distributed along the center of the reset worktable 2. The flip base plate 18 is located on top of the four flip support rods 17, and the flip positioning plate 19 is located on top of the flip base plate 18.
[0037] Four rotating support rods 17 are centrally symmetrically distributed to form a stable quadrilateral support frame, effectively distributing the load and reducing vibration during the rotating process, avoiding deformation or displacement caused by uneven force. The support rods serve as the basic support layer, providing the main load-bearing function. The rotating base plate 18 serves as an intermediate transition layer, connecting the support rods and the positioning plate, enhancing the overall rigidity. The rotating positioning plate 19 serves as the top positioning layer, precisely constraining the workpiece position. The combined design of the positioning plate and the base plate forms a dual positioning reference surface, ensuring that the workpiece always maintains the preset posture during the rotating process, avoiding displacement deviation caused by inertia.
[0038] like Figure 3 and Figure 4 As shown, the flipping assembly includes a flipping arm 20, a flipping base 21, a flipping shaft 22, a flipping connector 23, a flipping cylinder 24, and a flipping mounting plate 25. There are two flipping arms 20 and two flipping bases 21. The two flipping arms 20 and the two flipping bases 21 are symmetrically distributed along the center of the flipping positioning plate 19. One end of the two flipping bases 21 is bolted to the driving component 8. The flipping shaft 22 passes through and is rotatably connected to the flipping positioning plate 19, the two flipping arms 20, and the two flipping bases 21. The flipping connector 23 is set on the output shaft of the flipping cylinder 24 and is rotatably connected to the two flipping arms 20. One end of the flipping mounting plate 25 is bolted to the bottom of the flipping cylinder 24, and the other end is bolted to the driving component 8.
[0039] The flipping base 21 is a flipping base 21 with bearings. The through-type flipping shaft 22 integrates the positioning plate, flipping arm 20 and base into a rigid linkage body, eliminating the gap error of the traditional hinge structure. In use, the flipping cylinder 24 generates force and transmits the force to the flipping joint 23. The flipping joint 23 drives the flipping arm 20 to rotate accordingly through the rotational connection with the flipping arm 20. The other end of the flipping arm 20 is rotatably connected to the flipping positioning plate 19. Through the connection between the flipping positioning plate 19 and the flipping support rod 17 and the flipping base plate 18, the flipping positioning plate 19 can drive the conversion between the material picking worktable 1 and the reset worktable 2, realizing the conversion between material picking and resetting functions.
[0040] Working principle: When it is necessary to pick up or release material from the ball valve, the gripper cylinder 4 controls the pneumatic gripper 5 to grip or release the ball valve. When the reset function is required, the output shaft of the drive cylinder 12 causes the drive plate 11 to move, and the drive plate 11 drives the reset ring 7 to move accordingly, so that the fixed ring 29 in the prior art is reset accordingly. The conversion between the pneumatic gripper 5 and the reset ring 7 is achieved by the force generated by the flipping cylinder 24, which is transmitted to the flipping joint 23. The flipping joint 23 drives the flipping arm 20 to rotate accordingly through the rotatable connection with the flipping arm 20. The other end of the flipping arm 20 is rotatably connected to the flipping positioning plate 19. Through the connection between the flipping positioning plate 19, the flipping support rod 17, and the flipping base plate 18, the flipping positioning plate 19 can drive the conversion between the picking worktable 1 and the reset worktable 2.
