[0020] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Please refer to Figure 1 The embodiment of the utility model provides a rotary material turning mechanism, including a turntable 51, a material turning device 52, a rotary drive device 53, a rotary material turning support 54, and a flipping and lifting device 55. The various components of this embodiment are described in detail below in conjunction with the accompanying drawings.

[0022] like Figure 1 and Figure 2 As shown, the rotary drive device 53 can be upward on the rotary material turning support 54 and its output part extends out of the top surface of the rotary material turning support 54. The bottom surface of the turntable 51 is transmission connected with the output part of the rotary drive device 53 and is driven to rotate by the rotary drive device 53. The turning device 52 is provided with four and is horizontally and rotatably arranged on the four corners of the top surface of the turntable 51. The four corners of the top surface of the turntable 51 are located below the turning device 52 and are respectively penetrated by corresponding through holes 511. The flipping and lifting device 55 is installed upward on the rotary material turning support 54 and is located on one side of the rotary drive device 53. The output shaft of the flipping and lifting device 55 extends out of the top surface of the rotary material turning support 54.

[0023] In specific implementation, when the rotary drive device 53 can drive the turntable 51 to rotate and each of its through holes 511 is located above the output shaft of the flipping and lifting device 55 in sequence, the output shaft of the flipping and lifting device 55 can pass through the corresponding through holes 511 and move upward to lift the turning device 52 to turn it over, and then move downward to restore the turning device 52 to a horizontal state.

[0024] Among them, each through hole 511 on the turntable 51 enables the flipping and lifting device 55 to smoothly contact the material turning device 52, ensuring the smoothness and accuracy of the flipping operation, helping to improve work efficiency and reliability, and ensuring the consistency of blank processing.

[0025] like Figure 3As shown, the rotary drive device 53 may include a rotating shaft 531, a coupling 532, a crossed roller bearing 533, a rotary drive motor 534, and a rotary motor mounting plate 535. The rotary drive motor 534 is fixedly arranged below the top surface of the rotary tipping support 54 through the rotary motor mounting plate. The top end of the rotating shaft 531 passes through the top surface of the rotary tipping support 54 and is fixedly connected to the bottom surface of the turntable 51. The bottom end of the rotating shaft 531 is drivingly connected to the output shaft of the rotary drive motor 534 through the coupling 532 and drives it to rotate. The crossed roller bearing 533 is sleeved on the rotating shaft 531 and is located between the top surface of the rotary tipping support 54 and the turntable 51.

[0026] Among them, the coupling 532 can play a role in transmitting torque, can effectively buffer the deviation caused by mechanical assembly errors, increase the stability of the system, reduce wear, and extend the service life. The crossed roller bearing 533 can reduce friction, enable the rotating shaft 531 to rotate smoothly, has high load-bearing capacity and rigidity, and helps to improve its rotation accuracy and flexibility.

[0027] Preferably, the flipping and jacking device 55 can be set as a lifting drive cylinder.

[0028] Preferably, the turntable 51 can be set as a cross-shaped structure. Among them, the tipping device 52 is respectively arranged at the ends of the extension arms of the cross-shaped turntable. The structure is compact, can better support the distribution of the tipping device, improve the overall stability of the turntable, and can quickly align the flipping and jacking device with the tipping device during operation, improving the flipping efficiency.

[0029] Such as Figure 4 and Figure 5As shown in the figure, each material turning device 52 may include a hinge seat 521, a rotating rod 522, a turning block 523, a reset torsion spring 524, a positioning fixture 525, an abutting block 526, and a support rod 528. The hinge seat 521 is fixedly arranged on the turntable 51. Both ends of the rotating rod 522 are rotatably installed between the inner walls at both ends of the hinge seat 521. The structure of the turning block 523 is L-shaped. One end of the horizontal section of the turning block 523 is rotatably installed on the hinge seat 521 through the rotating rod 522. The bottom surface of the positioning fixture 525 is fixedly arranged on the top surface of the horizontal section of the turning block 523. The positioning fixture 525 is provided with a plurality of positioning grooves 5251 for placing round bar-shaped blanks. One side surface of the abutting block 526 is fixedly arranged on one side surface of the vertical section of the turning block 523 and is located on one side of the positioning fixture 525. The horizontal height of the abutting block 526 is higher than the horizontal height of the positioning fixture 525, and an abutting platform 5261 is formed at the higher part. The reset torsion spring 524 is sleeved on the rotating rod 522 and is located between the through grooves 5231 at one end of the vertical section of the turning block 523. The first rotating arm 5241 and the second rotating arm 5242 at both ends of the reset torsion spring 524 both extend outward and are respectively located on the back surface and below the turning block 523. There are two support rods 528, which are respectively and spacedly fixedly arranged at the bottom of the turning block 523 and can be in contact with the top surface of the turntable 51 when the turning block 523 is in a horizontal state.

[0030] As Figure 6 shown in the figure, the material turning device 52 may further include a limiting piece 527. The limiting piece 527 is inclined towards the direction close to the second rotating arm 5242 and is arranged on the hinge seat 521 and is located below the reset torsion spring 524.

[0031] Furthermore, the reset torsion spring 524 can provide a restoring force for the turning block 523, so that it can automatically return to the horizontal state after turning. The limiting piece 527 limits the turning angle of the second rotating arm 5242, prevents it from turning over, and can ensure the quick reset of the material turning device 52 after each turning, ensuring the continuous operation efficiency. In addition, the support rod 528 can enhance the stability of the turning block 523, prevent tilting caused by the influence of gravity during the rotation process, and ensure the smooth progress of the material turning action.

[0032] In this embodiment, in order to increase the friction force on the positioning fixture 525 and the abutting block 526 and prevent the blank from slipping during docking, it may further include a flannelette 529 and a flannelette pad 5291. The flannelette 529 is fixedly connected to the inner wall surface of the positioning groove 5251 on each positioning fixture 525. The flannelette pad 5291 is fixedly connected to the abutting platform 5261 of the abutting block 526. The flannelette 529 and the flannelette pad 5291 can improve the anti-slip effect of the blank between the inner wall of the positioning groove 5251 and the abutting platform 5261.

[0033] The working principle of this embodiment is as follows:

[0034] When the rotary drive device drives the through holes on the turntable to rotate above its output shaft in sequence and enables the external blank feeding mechanism to transfer the blank in a vertical state above the turnover device for docking, the output shaft of the turnover lifting device moves upward to lift and turn over the turnover block. At the same time, the bottom of the blank first contacts the abutting platform, and then the output shaft of the turnover lifting device descends, and the turnover block resets. The blank falls into the positioning groove under the action of gravity, and thus the turnover from the vertical state to the horizontal state is completed. Then, the rotary drive device drives the blank on the turntable to rotate to the material suction station, facilitating the external material suction mechanism to suck the blank in the horizontal state for blank discharging work, and finally sending it to the next production station.

[0035] In summary, the utility model can realize turning the blank transferred vertically into a horizontal state and achieving rapid station conversion. It has a high degree of automation, ensures the coherence of the process, operates stably and reliably, reduces manual intervention, and improves work efficiency.

[0036] The above embodiments are the preferred embodiments of the utility model, but the embodiments of the utility model are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications made without departing from the spirit and principle of the utility model shall be equivalent replacement methods and are all included in the protection scope of the utility model.
