Referring to fig. 1 to 6, the present utility model proposes an embodiment, in which a synchronous turning device 100 includes a clamping mechanism 2, a turning mechanism 1, and an angle detecting mechanism 3. The clamping mechanism 2 is provided with a movable space. The turnover mechanism 1 comprises a first turnover mechanism 101 and a second turnover mechanism 102, the first turnover mechanism 101 and the second turnover mechanism 102 are arranged in the movable space at intervals and are opposite to each other, and the first turnover mechanism 101 and the second turnover mechanism 102 are used for clamping products. The angle detection mechanism 3 includes a first angle detection mechanism 301 and a second angle detection mechanism 302, the first angle detection mechanism 301 is connected to the first turnover mechanism 101 and electrically connected to the second turnover mechanism 102, and the second angle detection mechanism 302 is connected to the second turnover mechanism 102 and electrically connected to the first turnover mechanism 101.

Specifically, the frame is longmen truss or section bar frame, fixture 2 fixed connection in the frame. A movable space is arranged below the clamping mechanism 2, and two turnover mechanisms 1 are connected to the clamping mechanism 2, positioned on two sides of the movable space and arranged in opposite directions. The clamping mechanism 2 can drive the turnover mechanism 1 to clamp products from two sides along the horizontal direction in the space, and then the turnover mechanism 1 rotates the products by 180 degrees to finish turnover operation.

And, each of the tilting mechanisms 1 is connected with one angle detecting mechanism 3, the angle detecting mechanism 3 detects a rotation parameter of the connected tilting mechanism 1, and the other tilting mechanism 1 is electrically connected.

Meanwhile, the two synchronous driving systems are mutually provided with motion feedback of the other side, and form closed-loop real-time monitoring.

Further, the angle detecting mechanism 3 may be an angle sensor, and the rotation parameter of the turning mechanism 1 is transmitted to the angle sensor through gear transmission, so that the angle sensor can feed back the rotation parameter to the other turning mechanism 1. Alternatively, it will be appreciated that each movement means is typically provided with a motor, so that the operating parameters of the motor may also be fed back to another motor by a monitoring device that is self-contained or designed.

Alternatively, a plurality of turnover mechanisms 1 are provided in one clamping mechanism 2, and a small movable space is formed between each pair of turnover mechanisms 1.

Further, when there are only two tilting mechanisms 1, the angle detection mechanisms 3 provided on the two tilting mechanisms 1 mutually transmit the rotation parameters of the tilting mechanism 1 to which they are connected to the other tilting mechanism 1, thereby realizing closed-loop feedback control. When the number of turnover mechanisms 1 exceeds two, the angle detection mechanism 3 feeds back the rotation parameters of the connected turnover mechanisms 1 to the other turnover mechanism 1 to form a feedback chain, and the last angle detection mechanism 3 feeds back the rotation parameters to the original turnover mechanism 1 to form a closed loop feedback control.

Wherein the internal monitoring system of the servo motor can be used as the angle detection mechanism 3 of the present application. It can be understood that the internal monitoring system of the servo motor can make the performance precision of the synchronous control system of the application higher, but the cost of the servo motor can be higher than that of other motors matched with the angle detection mechanism 3, and the cost can be chosen by referring to different requirements.

The two rails 41 are connected to the accommodating cavity in the vertical direction, and are located at two sides of the accommodating cavity, and two ends of the synchronous turning device 100 are movably connected to the rails 41. The lifting driving member 42 is connected to the machine 200 in a transmission manner. The belt 43 is in driving connection with the lifting drive 42, and the synchronous turning device 100 is connected to the belt. The lifting driving member 42 drives the driving belt 43 to drive the synchronous turning device 100 to ascend or descend along the track 41.

Specifically, the lifting device 400 is connected to the machine 200, the synchronous turning device 100 is connected to the lifting device 400, and the lifting device 400 drives the synchronous turning device 100 to ascend or descend.

Further, the lifting driving member 42 includes two sets of guide rails, a synchronous wheel synchronous belt assembly and a motor, the guide rails and the synchronous wheel synchronous belt assembly are disposed on two sides of the frame along the vertical direction, and the two sets of guide rails form a track 41. The clamping mechanism 2 is connected to the guide rail and synchronous wheel synchronous belt assemblies on both sides. The motor drives the synchronous wheel synchronous belt assembly to drive the synchronous turning device 100 to move along the vertical direction.

Further, the synchronizing gear set 44 comprises three bar-shaped parts with bevel gears, wherein two bar-shaped parts are connected with the synchronizing wheel and synchronizing belt assembly, and the other bar-shaped part is connected with the bar-shaped parts with the synchronizing wheel and synchronizing belt assembly, wherein the motor can drive the synchronizing wheel and synchronizing belt assemblies at two sides to move simultaneously through the meshing of the bevel gears.

Through the embodiment, when the synchronous turning device 100 clamps the product, the lifting device 400 drives the synchronous turning device 100 to ascend, so that enough space is reserved for turning action, and after the turning action is completed, the lifting device 400 descends to put down the turned product. Wherein, synchronous belt synchronizing wheel assembly can promote synchronous turning device 100 faster than the lead screw. Meanwhile, the synchronous wheel synchronous belt assemblies on two sides are connected through the synchronous gear set 44, so that the running time, the running angle and the running speed of the synchronous wheel synchronous belt assemblies on two sides are consistent, and the synchronous turning device 100 arranged along the length direction is prevented from inclining when being lifted or lowered, so that the guide rails on two sides are subjected to torque force, and unnecessary abrasion is caused.

The foregoing description is only of the preferred embodiments of the present utility model and is not intended to limit the scope of the utility model, and all equivalent structural changes made by the description of the present utility model and the accompanying drawings or direct/indirect application in other related technical fields are included in the scope of the utility model.
