[0002] In intelligent production lines and related training platforms for industrial robots, a part flipping module is often set on a rotary worktable to facilitate part gripping and assembly. The part flipping module is used to achieve the function of flipping and turning over parts. Currently, most of these are achieved by adding a new module and then having the robot grip the workpiece to achieve the part flipping and turning over.
[0003] In the prior art, such as the patent with publication number CN204545984U, a rotating worktable with a flipping function is disclosed, which includes a worktable, a base plate, a rotating support base, a flipping plate, and a flipping assembly for driving the flipping plate to flip.

[0004] The above structure improves the rotating panel based on the rotary worktable, allowing each workstation to be flipped at a certain angle. However, it requires additional special parts such as a flipping module to be added in conjunction with the rotating panel, which increases the manufacturing cost. Utility Model Content
[0005] In view of this, the purpose of this utility model is to propose a part flipping device based on a rotary worktable, so as to solve the problem that additional special part flipping modules are needed when flipping is performed by using a motor or other structures in conjunction with a rotating panel.
[0006] To achieve the above objectives, this utility model provides a part flipping device based on a rotary worktable, including a flipping device fixedly installed at the center of the worktable. The flipping device includes a base plate fixedly installed on the worktable, a base fixedly installed on the base plate, a locator fixedly installed on the top of the base, a top rod fixedly installed on the upper edge of the locator, and two sets of positioning rods provided on one side of the top rod. The positioning rods are used to engage with the workpiece.
[0007] The positioner and the base have openings, and the openings accommodate clamping rods, with the top of the clamping rods extending out of the openings.
[0008] A compression spring is fixedly installed at the bottom of the clamping rod. One end of the compression spring is fixedly connected to the bottom of the clamping rod, and the other end abuts against the bottom inner wall of the opening.
[0009] Preferably, the clamping rod has a notch at its top end and is an inverted T-shaped structure.
[0010] Preferably, the outer side of the notch is chamfered, and a rubber pad is provided at the top of the notch.
[0011] Preferably, the two sets of positioning rods are arranged vertically and vertically, and the diameter of the positioning rods is slightly smaller than the inner diameter of the workpiece.
[0012] Preferably, the positioning rod and the clamping rod are arranged correspondingly to each other, and the positioning rod and the clamping rod are used to restrict the external position of the workpiece.
[0013] Preferably, multiple sets of mounting screws are fixedly installed between the base plate and the worktable, between the base plate and the base, and between the base and the locator. The mounting screws are arranged in a mirror-symmetrical manner with respect to the center of the base.
[0014] The beneficial effects of this utility model are:
[0015] The flipping device is fixed at the central axis of the worktable. The robot gripper aligns the inner hole of the workpiece with the positioning rod on one side of the top rod of the locator, and then gradually pushes it to the bottom. Once the workpiece is pushed into place, it is positioned and clamped by the positioning rod and clamping rod. Then, the worktable is rotated 180° to turn the workpiece to the opposite side. The robot gripper then inserts into the inner hole of the workpiece to remove it, completing the workpiece flipping. Installed on an existing rotary worktable, it does not require an additional special parts flipping module, reducing manufacturing costs. At the same time, it simplifies the difficulty and running time of robot flipping, improving efficiency. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.
[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a part flipping device based on a rotary worktable includes a flipping device fixedly installed at the center of the worktable 10. The flipping device includes a base plate 1 fixedly installed on the worktable 10, a base 2 fixedly installed on the base plate 1, a locator 3 fixedly installed on the top of the base 2, a top rod 7 fixedly installed on the upper edge of the locator 3, and two sets of positioning rods 8 provided on one side of the top rod 7. The positioning rods 8 are used to engage with the workpiece 12.
[0025] The positioner 3 and the base 2 have an opening 13, and the opening 13 accommodates a clamping rod 4. The top end of the clamping rod 4 extends out of the opening 13.
[0026] A compression spring 5 is fixedly installed at the bottom of the clamping rod 4. One end of the compression spring 5 is fixedly connected to the bottom of the clamping rod 4, and the other end abuts against the bottom inner wall of the opening 13.
[0027] In this embodiment, the flipping device is fixed on the central axis of the worktable 10. The robot gripper 11 aligns the inner hole of the workpiece 12 with the positioning rod 8 on one side of the top rod 7 on the locator 3, and then gradually pushes it to the bottom. When the workpiece 12 is pushed into place, it is positioned and clamped by the locator 3, the top rod 7 and the clamping rod 4. Then, the worktable 10 is rotated 180° to turn the workpiece 12 to the opposite side. The robot gripper 11 then inserts into other inner holes of the workpiece 12 to remove it, thus completing the flipping of the workpiece 12. It can be installed on the existing rotary worktable 10 without the need for an additional special parts flipping module, which reduces manufacturing costs.
[0028] As one implementation method, such as Figure 2 , Figure 3 and Figure 4 As shown, the top of the clamping rod 4 has a notch 9, and the clamping rod 4 has an inverted T-shaped structure.
[0029] In this embodiment, when the robot gripper 11 aligns the inner hole of the workpiece 12 with the positioning rod 8 on one side of the top rod 7 of the locator 3, during the movement, the workpiece 12 first contacts the chamfer of the notch 9. Through the guiding action of the inclined surface of the notch 9 at the top of the clamping rod 4, the clamping rod 4 and the compression spring 5 will be gradually compressed downward, and the clamping force on the workpiece 12 will be maintained to prevent the workpiece 12 from moving.
[0030] As one implementation method, such as Figure 2 As shown, the outer side of notch 9 is chamfered, and a rubber pad is provided on the top of notch 9.
[0031] In this embodiment, the rubber pad on the notch 9 protects the outside of the workpiece 12, preventing wear on the outside of the workpiece 12 during the process of the robot gripper 11 pushing the inner hole of the workpiece 12 to the positioning rod 8 to the bottom.
[0032] As one implementation method, such as Figure 2 and Figure 4 As shown, the two sets of positioning rods 8 are arranged vertically and vertically, and the diameter of the positioning rods 8 is slightly smaller than the inner diameter of the workpiece 12.
[0033] In this embodiment, the robot gripper 11 aligns the inner hole of the workpiece 12 with the positioning rod 8 on one side of the top rod 7 on the locator 3, and then gradually pushes it to the bottom. When the workpiece 12 is pushed into place, the positioning rod 8 is inserted into the inner hole of the workpiece 12. Then, the worktable 10 is rotated 180° to turn the workpiece 12 to the opposite side. The robot gripper 11 is then inserted into other inner holes of the workpiece 12 to remove it, thus completing the flipping of the workpiece 12.
[0034] As one implementation method, such as Figure 4 and Figure 5 As shown, the positioning rod 8 and the clamping rod 4 are arranged correspondingly to each other, and the positioning rod 8 and the clamping rod 4 are used to restrict the external position of the workpiece 12.
[0035] In this embodiment, when the workpiece 12 is pushed to the positioning rod 8, the top rod 7 located at the top of the positioner 3, combined with the clamping action of the bottom clamping rod 4, clamps the entire workpiece 12 to prevent it from falling off during the flipping process.
[0036] As one implementation method, such as Figure 3 As shown, multiple sets of mounting screws 6 are fixedly installed between the base plate 1 and the worktable 10, between the base plate 1 and the base 2, and between the base 2 and the locator 3. The mounting screws 6 are arranged in a mirror symmetrical manner with the center of the base 2 as the reference.
[0037] In this embodiment, the flipping device is assembled using mounting screws 6, and the flipping device is fixed to the central axis position of the worktable 10 using mounting screws 6. The worktable 10 can be rotated around the central axis by a specified angle through the control system.
[0038] Working principle: In use, the flipping device is assembled using mounting screws 6 and fixed to the central axis of the worktable 10 using mounting screws 6. The robot gripper 11 aligns the inner hole of the workpiece 12 with the positioning rod 8 on one side of the top rod 7 on the locator 3, and then gradually pushes it to the bottom. During this process, the workpiece 12 is guided by the inclined surface of the notch 9 at the top of the clamping rod 4, which gradually compresses the clamping rod 4 and the compression spring 5, maintaining a clamping force on the workpiece 12. When the workpiece 12 is pushed into place, it is positioned and clamped by the locator 3, the top rod 7, and the clamping rod 4. Then, the worktable 10 is rotated 180° to turn the workpiece 12 to the opposite side. The robot gripper 11 then inserts into the inner hole of the workpiece 12 to remove it, completing the flipping of the workpiece 12. It can be installed on the existing rotary worktable 10 without the need for an additional special parts flipping module, thus reducing manufacturing costs.
