The first moving member 11, the second moving member 12, the third moving member 13, the first auxiliary member 14, the second auxiliary member 15, and the workpiece to be flipped are arranged on the flipping base 17.

[0043] Furthermore, the first moving member 11, the second moving member 12, the third moving member 13, the first auxiliary member 14, and the second auxiliary member 15 can be selectively arranged on the flipping base 17, and the first moving member 11, the second moving member 12, the third moving member 13, the first auxiliary member 14, and the second auxiliary member 15 can rotate in a vertical plane.

[0044] Furthermore, the flipping device further includes a clamping portion. The clamping portion is fixedly connected to the flipping base 17. The workpiece to be flipped can be detachably clamped on the clamping portion, and the clamping portion flips together with the flipping portion 1.

[0045] The first moving member 11, the second moving member 12, and the third moving member 13 are evenly arranged along the circumference of the flipping base 17. The first moving member 11, the second moving member 12, and the third moving member 13 are located in a first plane. The projection of the first auxiliary member 14 in the first plane is located between the first moving member 11 and the second moving member 12, and the projection of the second auxiliary member 15 in the first plane is located between the second moving member 12 and the third moving member 13, which can make the first moving member 11 and the first auxiliary member 14 contact the support platform 3 simultaneously, and the third moving member 13 and the second auxiliary member 15 contact the support platform 3 simultaneously, ensuring the stable movement of the flipping portion 1 on the support platform 3.

[0046] Furthermore, the first moving member 11, the second moving member 12, and the third moving member 13 are evenly arranged along the circumference with the center of the flipping base 17 as the center of the circle, and the angles formed between the connecting lines of the first moving member 11, the second moving member 12, and the third moving member 13 and the center of the flipping base 17 are 60°.

[0047] The first auxiliary member 14 and the second auxiliary member 15 are located in the second plane, the second plane is parallel to the first plane, the distance L1 between the center of the first auxiliary member 14 and the center of the first moving member 11, the distance L2 between the center of the first auxiliary member 14 and the center of the second moving member 12, the distance L3 between the center of the second auxiliary member 15 and the center of the second moving member 12, and the distance L4 between the center of the second auxiliary member 15 and the center of the third moving member 13 are L1=L2=L3=L4. That is, the center of the first auxiliary member 14 is located on the bisector of the 60° angle formed by the center of the first moving member 11, the center of the second moving member 12 and the center of the flipping member. The center of the second auxiliary member 15 is located on the bisector of the 60° angle formed by the center of the second moving member 12, the center of the third moving member 13 and the center of the flipping member.

[0048] The first moving member 11 , the second moving member 12 , the third moving member 13 , the first auxiliary member 14 and the second auxiliary member 15 are rollers of the same size, which ensure the stability of the flipping part 1 when flipping.

[0049] Furthermore, the first moving member 11 , the second moving member 12 , and the third moving member 13 are rollingly arranged on the first track 33 , and the first auxiliary member 14 and the second auxiliary member 15 are rollingly arranged on the second track 34 .

[0050] When the flipping part 1 is in the first state, the shortest distance between the second moving part 12 and the supporting platform 3 is greater than the maximum distance between the first protrusion 21 and the supporting platform 3, that is, when the flipping part 1 is in the first state, the distance between the bottom end of the second moving part 12 and the top end of the supporting platform 3 is greater than the height of the first protrusion 21, ensuring that when the first moving part 11 contacts the first protrusion 21, the second moving part 12 can cross the top of the first protrusion 21 so that the flipping part 1 can flip.

[0051] Furthermore, when the flip portion 1 is in the second state, the distance between the bottom end of the first moving member 11 and the top end of the supporting platform 3 is greater than the height of the second protrusion 22 .

[0052] The motion path of the first auxiliary member 14 and the second auxiliary member 15 on the support platform 3 is the second path, the toggle portion 2 further includes a third protrusion 23, the third protrusion 23 is located on the second path, the first protrusion 21, the second protrusion 22 and the third protrusion 23 are symmetrical structures, the symmetry axes of the first protrusion 21, the second protrusion 22 and the third protrusion 23 are perpendicular to the support platform 3, the distance between the symmetry axis of the first protrusion 21 and the symmetry axis of the third protrusion 23 is A1, the distance between the symmetry axis of the second protrusion 22 and the symmetry axis of the third protrusion 23 is A2, A1=A2. That is, the projection of the third protrusion 23 on the circumferential surface where the first protrusion 21 and the second protrusion 22 are located is located in the middle of the first protrusion 21 and the second protrusion 22.

[0053] Further, the first path is located on the outer peripheral side of the second path, that is, the radius of the first path is greater than the radius of the second path.

[0054] Further, the shape and size of the third protrusion 23 are the same as those of the first protrusion 21 and the second protrusion 22.

[0055] The support platform 3 is provided with a first avoidance groove 31 and a second avoidance groove 32. The first avoidance groove 31 and the second avoidance groove 32 are arranged along the second path. The first avoidance groove 31 is arranged on one side of the third protrusion 23, and the second avoidance groove 32 is arranged on the other side of the third protrusion 23. When the first moving part 11 contacts the first protrusion 21, the first auxiliary part 14 can enter the first avoidance groove 31. When the third moving part 13 contacts the second protrusion 22, the second auxiliary part 15 can enter the second avoidance groove 32. By providing the first avoidance groove 31 and the second avoidance groove 32, when the first moving part 11 contacts the first protrusion 21, the first auxiliary part 14 can enter the first avoidance groove 31. When flipping, there may be a large frictional force between the first auxiliary part 14 and the second track 34. After giving way, the first auxiliary part 14 is suspended, reducing the frictional force, so that the flipping part 1 can flip smoothly.

[0056] Further, the first avoidance groove 31 is arranged on the upstream side of the third protrusion 23 along the moving direction of the flipping part 1, and the second avoidance groove 32 is arranged on the downstream side of the third protrusion 23 along the moving direction of the flipping part 1.

[0058] The flipping device further includes a connecting part 4 and a driving part. The driving part is connected to the flipping part 1 through the connecting part 4 to drive the flipping part 1 to move on the support platform 3. At least a part of the connecting part 4 can move in a direction close to or away from the support platform 3. By providing the driving part, power is provided for the movement of the flipping part 1 and the workpiece to be flipped. The connecting part 4 is used to transmit the driving force provided by the driving part.

[0059] Further, the driving part provides a driving force for circumferential rotation along the support platform 3, driving the connecting part 4, the flipping part 1 and the workpiece to be flipped to rotate circumferentially along the support platform 3.

[0060] The connecting part 4 includes a first connecting rod 41 and a second connecting rod 42. The first end of the first connecting rod 41 is connected to the driving part, the second end of the first connecting rod 41 is connected to the second connecting rod 42, and the end of the second connecting rod 42 far from the first connecting rod 41 is sleeved in the flipping part 1. A limiting ring 411 is arranged on the first connecting rod 41, and a limiting rod 421 is arranged on the second connecting rod 42. The limiting rod 421 is sleeved in the limiting ring 411, and the limiting rod 421 can slide in the limiting ring 411 so that the second connecting rod 42 can move towards or away from the support platform 3. By arranging the limiting ring 411 and the limiting rod 421, the second connecting part can rotate in a vertical plane with the limiting rod 421 as the axis. At the same time, the limiting rod 421 can also slide up and down in the limiting ring 411, so as to avoid the connecting rod being stressed and damaged when the first protrusion 21, the second protrusion 22 and the third protrusion 23 move on the flipping part 1.

[0061] Further, the second connecting rod 42 passes through the flipping seat 17, and the flipping seat 17 can rotate on the second connecting rod 42.

[0062] Further, the flipping device further includes a rotating disk 43. The rotating disk 43 is coaxially arranged with the support platform 3 at the top of the support platform 3. The end of the second connecting rod 42 far from the flipping part 1 is arranged on the rotating disk 43. The driving part drives the rotating disk 43 to rotate to drive the first connecting rod 41 and the second connecting rod 42 to rotate.

[0063] Further, the second connecting rod 42 is arranged on the outer wall of the rotating disk 43 along the radial direction of the rotating disk 43.

[0064] Further, a third track 35 is arranged on the top surface of the support platform 3. A support wheel 44 is arranged at the bottom of the end of the first connecting rod 41 close to the second connecting rod 42. The support wheel 44 is slidably arranged on the third track 35.

[0065] Further, in this embodiment, 12 connecting parts 4 are uniformly arranged on the outer wall of the rotating disk 43. A flipping part 1 is arranged on each connecting part 4, and a workpiece to be flipped can be connected to each flipping part 1. When the rotating disk 43 rotates one week, 12 workpieces to be flipped can be flipped.

[0066] Before starting the machine, fix the workpiece to be turned on the clamping part, and multiple workpieces to be turned can be assembled according to actual needs. After starting the machine, the driving part drives the rotating disk 43 to rotate, and the rotating disk 43 drives the connecting part 4, the turning part 1, the clamping part and the workpiece to be turned to rotate along the circumferential direction of the supporting platform 3. When the movement reaches the position of the toggle portion 2, the first moving part 11 contacts and interacts with the first protrusion 21. The first protrusion 21 gives the first moving part 11 a rotational torque, driving the flip seat 17 and the clamping part to flip. When the first moving part 11 contacts the first protrusion 21, the first auxiliary part 14 on the second track 34 is just located at the first avoidance groove 31. The first avoidance groove 31 makes way for the flipping of the first auxiliary part 14, because there may be a large friction between the first auxiliary part 14 and the second track 34 during flipping. After making way, the first auxiliary part 14 is suspended to reduce friction. Then the flip part 1 continues to move to the right. The first auxiliary part 14 will contact the third protrusion 23. After contact, the third protrusion 23 will also provide a rotational torque to prevent the first protrusion 21 from rotating out of place, thereby playing a role in assisting rotation. When the first auxiliary part 14 is flipped, it is disengaged from the third protrusion 23. At this time, the second moving part 12 reaches the middle of the first protrusion 21 and the second protrusion 22. Figure 6 As shown, the intermediate state is reached, at which time the flip part 1 has flipped 90°, and then the second moving part 12 repeats the action of the first moving part 11, and the third moving part 13 repeats the action of the second moving part 12, completing the flip of 180°. If some special processes require secondary processing, the driving part can be reversed, passing through the second protrusion 22, the third protrusion 23 and the first protrusion 21 in the opposite direction, and flipping back to the first state. After the material has completed the process, the material can be replaced and flipped again, and this is a cycle.

[0067] A turning device provided in an embodiment of the present invention can avoid manual turning of workpieces, reduce manual labor, increase production efficiency, and simplify the process.

[0068] It is easy for those skilled in the art to understand that, under the premise of no conflict, the above-mentioned advantageous methods can be freely combined and superimposed.
