Description

Technical Field

[0001] The invention belongs to the technical field of mechanical equipment, and mainly relates to a turning device with automatic conveying and angle adjustment. Background Art

[0002] At present, industrial automation is the trend of widely using automatic control and automatic adjustment devices in industrial production to replace manual operation of machines and machine systems for processing and production. Under the conditions of industrial production automation, people only indirectly take care of and supervise the machines for production. In a complete processing production line, in addition to the necessary machine tools and equipment, the flipping devices for part posture conversion play a vital role. They significantly improve production efficiency, quality and safety through automation and precise operation. Especially in the automated production lines of large and medium-sized parts. They can automatically flip the workpiece from one side to another, thereby realizing efficient production automation flipping.

[0003] The Chinese utility model patent with application number 201520181921.2 discloses an automatic connection conveying and flipping device for assembling and conveying motor rotors, including a frame, a flip frame capable of flipping horizontally relative to the frame, a flip driving mechanism for driving the flip frame to flip, a connection conveying mechanism for an assembly conveying device that flips with the flip frame and carries and conveys the motor rotor and connects the two sides of the frame, the connection conveying mechanism comprising a lower connection conveying mechanism and an upper connection conveying mechanism that opens and closes opposite to the lower connection conveying mechanism, and a push-pull mechanism capable of pushing the upper connection conveying mechanism to reciprocate in the direction of the lower connection conveying mechanism and clamping the motor rotor is provided on the flipping frame. However, the upper and lower connecting rails in this application are driven by motors, and the rotation of the motor drives the sprocket through the chain. Because this structure needs to cooperate with the tensioning mechanism to operate, the entire upper and lower raceway system is bulky and complicated, and interference is easy to occur during angle changes and arrangements; and this application uses two parallel and synchronously rotating wheels, and the two wheels are connected by multiple connecting rods. The reducer drives only one of the wheels to rotate, and the other wheel only rotates under the drive of the connecting mechanism. This will cause power bias, which is very likely to cause safety accidents and the consequences are disastrous.

[0004] The Chinese utility model patent with application number 201920717945.3 discloses a conveying device capable of realizing horizontal rotation and vertical flipping of workpieces, including a horizontal rotation mechanism, a vertical flipping mechanism and a conveying roller. The horizontal rotation mechanism and the vertical flipping mechanism are connected through a rotating platform. The horizontal rotation reducer drives the slewing support to rotate through gears to realize horizontal rotation of the workpiece by 180 degrees. The flipping reducer drives the left and right hub wheels to flip through chains to realize vertical flipping of the workpiece by 180 degrees. A conveying roller composed of upper and lower rollers is installed between the left and right hub wheels so that the workpiece can be directly transported to the next process after flipping. Position limiting units are respectively provided on the horizontal rotation mechanism and the vertical flipping mechanism, and a material stopper and a backstop are respectively installed on the lower roller. At least one clamping device is provided on the wall panel on which the upper roller is installed. However, the vertical flipping mechanism in this application adopts the method of connecting the left hub wheel, the right hub wheel and the chain mounting plate as a whole through the pull column. The reducer drives only one of the hub wheels to rotate, and the other hub wheel rotates only under the drive of the pull column. This will cause power bias, just like the technical solution in the Chinese utility model patent with application number 201520181921.2. In addition, the rotating disk has only two supporting wheels and no pressure wheel on it. Once the signal fails, the reducer does not have a torque limiter safety device, and the reducer will pull down the flipping device and cause a safety accident. The consequences are disastrous. Summary of the invention

[0005] The purpose of the present invention is to provide a new technical solution to solve the above problems.

[0012] Two symmetrically arranged dead stops and a signal seat A and a signal seat B are respectively provided on the inner diameter of the rotating disk; the angle between the two dead stops is the flipping angle of the control part.

[0029] The present invention is described with reference to the accompanying drawings.

[0030] like Figure 1-Figure 8 As shown, a flipping device with automatic conveying and angle adjustment includes a conveying mechanism and a flipping mechanism; the conveying mechanism includes a front raceway 26 and a rear raceway 28 arranged in sequence front and back; the flipping mechanism is arranged between the front raceway 26 and the rear raceway 28; the flipping mechanism includes a fixed flipping support 1; a hollow shaft reducer 3, a signal fixed bracket 29, a rotating disk 7 and a rotating support wheel 5 are arranged on the fixed flipping support 1; the rotating disk 7 is arranged on a concentric axis inside the fixed flipping support 1, and three rotating support wheels 5 evenly distributed in the shape of isosceles triangles are arranged along the outer diameter surface of the rotating disk 7, and the rotating support wheel 5 is designed to be coaxial with the rotating disk 7 and the fixed flipping support 1; the hollow shaft reducer 3 is arranged on one side below the fixed flipping support 1, and a torque limiter 34 is arranged in its coaxial direction; the signal fixed bracket 29 is provided It is arranged on one side above the fixed flip support 1; a sprocket 19 is arranged on the torque limiter 34, and a chain 4 is arranged between the sprocket 19 and the rotating disk 7 to be connected to each other, and the end of the chain 4 is connected to the chain seat 14 arranged on the rotating disk 7; three uniformly distributed guide bars 15 are also arranged on the rotating disk 7; the guide bars 15 are distributed at the outer end position of the part 13 to ensure that the part 13 will not be offset during the conveying process; the present invention arranges a rotating disk 7, and the hollow shaft reducer 3 is driven to rotate by the chain 4, the power is centered, and the rotating disk 7 is not subjected to external force when rotating, and rotates smoothly; the three rotating support wheels 5 firmly fix the rotating disk 7 at the center, and there will be no overturning. A torque limiter 34 is also installed on the coaxial axis of the hollow shaft reducer 3, which adds an important link of safety, so this flipping device is truly safe.

[0031] The rotating disk 7 is provided with an upper raceway 12 and a lower raceway 6 with a power docking function; one side end of the upper raceway 12 is provided with a meshing tooth C33; one side end of the lower raceway 6 is provided with a meshing tooth B23, and the other side end thereof is provided with a flipping stopper 16; a part 13 is also provided between the upper raceway 12 and the lower raceway 6; the function of the flipping stopper 16 here is that after the part 13 enters the flipping mechanism, it will not retreat due to inertia due to the front blocking block 22 in front, which plays an important role in fixing the part 13 during flipping; the signal fixing bracket 29 is provided with a signal shaft 10, a spring 30, a block A17 and a block B32, a travel switch A11, and a travel switch B31, which together constitute the initial and in-position signal system of the flipping mechanism; when the flipping device is in the original position, the bearing 18 is in the signal position. On the plane of seat B35, when the rotating disk 7 rotates, it drives the signal seat A9 and signal seat B35 to rotate, and the bearing 18 rolls down the plane of B35. When it rotates into place, the bearing 18 on the signal shaft 10 rolls onto the step on the signal seat A9, which will cause the block A17 to hit the travel switch A11 to send a signal, and the rotating disk 7 rotates into place; when the rotating disk 7 rotates to the 180-degree position, that is, the position of the signal seat A9, since the heights of the signal seat B35 and the signal seat A9 in the radial direction are inconsistent, the signal seat A9 is farther from the center than the rolling surface of the bearing 18 of the signal seat B35. When the bearing 18 rolls onto the plane of the signal seat A9, the signal shaft 10 rises, and at this time the block A17 hits the travel switch A11 to send a signal, telling the electronic control system that the flip device is in the flip position at this time, and the hollow shaft reducer 3 stops.

[0032] The front roller 26 and the rear roller 28 are both provided with motors 27, and a meshing tooth A21 is also provided at one end of the rear roller 28; the meshing tooth A21 is adapted to the meshing tooth B23 and the meshing tooth C33; here, when the flipping mechanism is in the initial position, the lower roller 6 and the front roller 26 and the rear roller 28 form a transmission system, so that the part 13 enters the flipping mechanism, and when the flipping mechanism is in the flipped position, the upper roller 12 and the front roller 26 and the rear roller 28 form a transmission system, so that the part 13 is smoothly sent out of the flipping device to complete the flipping action; two opposing sensors 25 are provided on the roller frame of the lower roller 6 in the diagonal direction, and A liftable front stop block 22 is also provided at the rear end of the raceway 6, and a proximity switch B24 is provided on the raceway frame near the front stop block 22; a fixed dead stop seat 2 is provided on the fixed flip support 1 near the hollow shaft reducer 3; two symmetrically arranged dead stops 8 and a signal seat A9 and a signal seat B35 are also provided along the inner diameter of the rotating disk 7; the angle between the two dead stops 8 is the flip angle of the control part 13; here, the dead stop 8 is related to the arrangement of the signal seat A9 and the signal seat B35 on the rotating disk 7 and the flip angle of the flip mechanism, and their relative position angles can be set according to the required flip angle. degrees; when the part 13 rotates 180 degrees in the flip mechanism, the lower raceway 6 and the upper raceway 12 are arranged on the upper and lower sides of the part 13 and are symmetrical to the center of the rotating disk 7, that is, the two dead stops 8 and the two signal seats A9 and the signal seat B35 are arranged 180 degrees on the rotating disk 7 respectively; the rotating support wheel 5 is a concave structure with high sides and low middle, and the width of the groove is greater than the thickness of the rotating disk 7, which is used to limit the displacement of the rotating disk 7; the concave structure of the rotating support wheel 5 here can prevent the rotating disk 7 from tilting during rotation. During the design process, the center of gravity of the part 13 will be placed in the center of the rotating disk 7 as much as possible, which is conducive to smooth transportation and improves the safety factor of use; the The torque limiter 34 is also provided with a proximity switch A20 for limiting; the function of the proximity switch A20 here is that when the torque exceeds the torque limit of the torque, the stack spring will be deformed, so that the switch will have a signal and transmit it to the system; if a fault occurs and the torque exceeds the torque limit of the torque limiter 34 on the sprocket 19, the sprocket 19 will slip and idle with the shaft, and the rotating disk 7 will stop rotating to avoid accidents. At the same time, the proximity switch A20 on the torque limiter 34 will tell the system to stop the hollow shaft reducer 3, and at the same time tell the electronic control system that the flip mechanism has a fault, and give the operator an alarm to solve the problem. The torque limiter 34 plays a very important safety role.

[0033] When the present invention is in use, when the part 13 is conveyed to the front roller 26 of the flipping mechanism, the motor 27 of the rear roller 28 is started, and the meshing tooth A21 on the rear roller 28 starts to rotate through the drive of the bevel gear B39, and at the same time moves forward to mesh with the meshing tooth B23 and rotates, and at the same time drives the bevel gear A36 set at the end of the meshing tooth B23 to rotate, further driving the roller connected to it to rotate, and a double sprocket 37 is set at the end of the roller, and under the drive of the sprocket chain 38, all the rollers on the lower roller 6 are rotated, and driven by the friction force, the part 13 is smoothly advanced. When the proximity switch B24 and the through-beam sensor 25 in the flipping mechanism have signals, the meshing teeth A21 of the rear raceway 28 retreat. After the meshing teeth A21 retreat into place, the hollow shaft reducer 3 of the flipping mechanism starts to start, driving the rotating disk 7 to rotate. When the hollow shaft reducer 3 receives the in-place signal from the travel switch A11, the flipping mechanism flips into place, and the front blocking block 22 retreats (this device rises after the part 13 is transported out of the flipping mechanism). The meshing teeth A21 on the rear raceway 28 advance again to complete docking with the meshing teeth C33 of the upper raceway 12. The roller of the upper raceway 12 rotates to send the part 13 out and flip it, thus completing the flipping action; if the part 13 needs to be flipped 90 degrees, the upper raceway 12, the lower raceway 6, the dead stopper 8, the signal seat A9 and the signal seat B35 can be arranged at a 90-degree direction on the rotating disk 7, that is, the lower raceway 6 does not move, and the upper raceway 12 is disassembled and moved to a 90-degree direction to be installed and arranged, so that the part 13 can enter the flipping device when the roller of the lower raceway 6 rotates; after the rotating disk 7 rotates 90 degrees, the part leaves the flipping when the roller of the upper raceway 12 shifted to the 90-degree direction rotates; similarly, If the part 13 needs to be flipped 60 degrees, the upper raceway 12 and the lower raceway 6 are arranged at 60 degrees, and the dead stop block 8, the signal seat A9 and the signal seat B35 are also arranged at 60 degrees on the rotating disk 7, so that a 60-degree flip can be achieved; in this way, although the cavity inside the rotating disk 7 will be made in different styles according to the different angles of the part 13, the appearance of the overall flipping device is unified, making the entire production line beautiful and easy to organize and manage during production; in this way, the flipping mechanism can be flipped at any angle of 0-180 degrees, meeting the flipping posture requirements of the part 13 in the processing production line.

[0034] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, various equivalent transformations can be made to the technical scheme of the present invention, and these equivalent transformations all belong to the protection scope of the present invention.
