Description

Technical Field

[0001] The utility model relates to the technical field of rotary positioning machines, and particularly relates to a rotary orientation mechanism of an O rotary positioning machine. Background Technique

[0002] A rotary positioning machine is a device used to rotate and position objects in industrial production. It usually consists of a rotating platform and a control system, and can precisely control the rotation angle and positioning position of the object. Rotary positioning machines are widely used in automated production lines, assembly lines, and logistics systems, and can improve production efficiency and accuracy. Common applications include welding, assembly, inspection, packaging, and other fields.

[0003] In the existing processing and production process, the angle and position of the workpiece are adjusted by the rotation of the rotary positioning mechanism, and then the upper processing component processes a specific position. However, the rotation can only be planar, which has great limitations. When the side or bottom also needs to be processed, it is usually necessary to manually reposition the workpiece, which is not convenient and affects the work efficiency. Secondly, due to the different shapes of the workpieces, it may be difficult to firmly clamp irregular workpieces, and the workpiece may shift during the processing, thus affecting the quality of the workpiece. Content of the Utility Model

[0004] The utility model provides a rotary orientation mechanism of an O rotary positioning machine, which has the advantages of being able to firmly clamp processing components with different shapes, quickly flip and adjust the components, and process different positions, so as to solve the problems in the prior art that it may be difficult to firmly clamp irregular components and it is not convenient enough to affect the work efficiency when processing multiple different positions.

[0005] To achieve the purpose of being able to firmly clamp processing components with different shapes, quickly flip and adjust the components, and process different positions, the utility model provides the following technical solution: A rotary orientation mechanism of an O rotary positioning machine, including a mounting frame. Arc-shaped sliding grooves are provided on the inner walls of both sides of the mounting frame. Arc-shaped sliders are slidably connected inside the two arc-shaped sliding grooves. A bottom frame is arranged inside the mounting frame. The two sides of the bottom frame are respectively fixedly connected to the two arc-shaped sliders. A fixed ring is fixedly connected to the top surface of the bottom frame. A rotating disk is arranged inside the fixed ring. Four clamping sliding grooves are provided on the top surface of the rotating disk. Clamping components are arranged on the tops of the four clamping sliding grooves.

[0006] Preferably, four sliding connection blocks are fixedly connected to the outer surface of the rotating disk. All four sliding connection blocks extend into the fixed ring and are slidably connected. A first motor is fixedly connected to the inner bottom end of the chassis. The output end of the first motor is fixedly connected to the rotating disk. The rotation of the output end of the first motor drives the rotation of the rotating disk. The four sliding connection blocks fixedly connected to the outside of the rotating disk slide inside the fixed ring. The rotation angle and positioning position of the workpiece are precisely controlled through the rotation of the rotating disk.

[0007] Preferably, two vertical plates are fixedly connected to the top surface of the mounting frame. Connecting rods are rotatably connected to the opposite sides of the two vertical plates. One end of the connecting rod extends to the outside of the arc-shaped slider and is fixedly connected to the arc-shaped slider. A second motor is fixedly installed on the other side of one of the vertical plates. The output end of the second motor is fixedly connected to one of the connecting rods. The rotation of the output end of the second motor drives the connecting rod. The rotation of the connecting rod drives the arc-shaped slider to slide inside the arc-shaped chute, so that the chassis fixedly connected between the two arc-shaped sliders rotates synchronously along the trajectory of the arc-shaped chute.

[0008] Preferably, first electric push rods are fixedly connected to the bottom surfaces of the four sliding connection blocks. The telescopic ends of the first electric push rods extend to the tops of the sliding connection blocks and are fixedly connected to a lifting plate. The lifting plate is pushed upward by the first electric push rods to lift the clamped workpiece, exposing its bottom surface.

[0009] Preferably, the clamping assembly includes an arc-shaped soft plate. A telescopic rod is fixedly connected to the bottom end of the arc-shaped soft plate. The telescopic rod is slidably connected inside the clamping chute. The workpiece placed on the surface of the rotating disk is clamped by the telescopic rod fixedly connected to the bottom sliding inside the clamping chute.

[0010] Preferably, the clamping assembly further includes two second electric push rods. Both second electric push rods are fixedly connected to one side of the lifting plate. The telescopic ends of both second electric push rods extend to the other end of the lifting plate and are fixedly connected to the arc-shaped soft plate. By the respective pushing of the two second electric push rods, the arc-shaped soft plate will bend and deform according to the shape of the workpiece to fit the outside of the workpiece.

[0011] Preferably, eight clamping small soft disks are installed on one side of the arc-shaped soft plate. The eight clamping small soft disks are linearly arranged in groups of four. The two groups of clamping small soft disks are symmetrically distributed. If the outer surface of the workpiece is uneven, the multiple clamping small soft disks installed on one side of the arc-shaped soft plate can well automatically adapt to the uneven surface of the outside of the workpiece, making the contact closer and the clamping more stable.

[0012] Compared with the prior art, the present utility model provides a rotation orientation mechanism of an O-rotation positioning machine, having the following beneficial effects:

[0013] 1. For the rotation and orientation mechanism of this O-rotation positioning machine, when machining the side and bottom surfaces of a workpiece, the rotation of the output end of the second motor drives the connecting rod, and the rotation of the connecting rod drives the arc-shaped slider to slide inside the arc-shaped chute, causing the chassis fixedly connected between the two arc-shaped sliders to rotate synchronously along the trajectory of the arc-shaped chute. The orientation of the workpiece can be adjusted by rotation, facilitating the machining of different parts of the workpiece, improving work efficiency and the machining quality of the workpiece, reducing the manual labor intensity, and making up for the large limitations of only planar rotation in the existing technology. When the side or bottom surface also needs to be machined, it usually requires manual repositioning and adjustment of the workpiece, which is not convenient and affects work efficiency.

[0014] 2. For the rotation and orientation mechanism of this O-rotation positioning machine, when facing workpieces with different shapes, through the separate control of the four arc-shaped flexible plates, and the arc-shaped flexible plates are separately pushed by the two second electric push rods, the arc-shaped flexible plates will bend and deform according to the shape of the workpiece to fit the outer side of the workpiece. If the outer surface of the workpiece is also uneven, through the multiple clamping small flexible disks installed on one side of the arc-shaped flexible plate, it can well automatically adapt to the uneven outer surface of the workpiece, making the contact closer and the clamping more stable.

Embodiment 1

A fixed ring 5 is fixedly connected to the top surface of the bottom frame 4. A rotating disk 6 is arranged inside the fixed ring 5. Four clamping sliding grooves 12 are provided on the top surface of the rotating disk 6. Clamping components are arranged on the tops of the four clamping sliding grooves 12.

[0023] The clamping component includes an arc-shaped soft plate 16. A telescopic rod 15 is fixedly connected to the bottom end of the arc-shaped soft plate 16. The telescopic rod 15 is slidably connected inside the clamping sliding groove 12.

[0024] The clamping component further includes two second electric push rods 17. Both of the two second electric push rods 17 are fixedly connected to one side of a lifting plate 14. The telescopic ends of the two second electric push rods 17 extend to the other end of the lifting plate 14 and are fixedly connected to the arc-shaped soft plate 16.

[0025] Eight clamping small soft disks 18 are installed on one side of the arc-shaped soft plate 16. The eight clamping small soft disks 18 are linearly arranged in groups of four. The two groups of clamping small soft disks 18 are symmetrically distributed.

[0026] Specifically, when facing workpieces with different shapes, through the separate control of the four arc-shaped soft plates 16, and the arc-shaped soft plates 16 are respectively pushed by the two second electric push rods 17, the arc-shaped soft plates 16 will bend and deform according to the shape of the workpiece to fit the outside of the workpiece. If the outer surface of the workpiece is also uneven, through the multiple clamping small soft disks 18 installed on one side of the arc-shaped soft plate 16, it can well automatically adapt to the uneven surface of the outside of the workpiece, making the contact closer and the clamping more stable. Embodiment 2

[0027] Based on the above Embodiment 1, please refer to Figure 1 and Figure 2, two vertical plates 8 are fixedly connected to the top surface of the mounting bracket 1. Connecting rods 9 are rotatably connected to the opposite sides of the two vertical plates 8. One end of each connecting rod 9 extends to the outside of the arc-shaped slider 3 and is fixedly connected to the arc-shaped slider 3. A second motor 10 is fixedly installed on the other side of one of the vertical plates 8, and the output end of the second motor 10 is fixedly connected to one of the connecting rods 9.

[0028] Four sliding connection blocks 7 are fixedly connected to the outer surface of the rotating disk 6. All four sliding connection blocks 7 extend into the fixed ring 5 and are slidably connected. A first motor 11 is fixedly connected to the bottom end inside the chassis 4, and the output end of the first motor 11 is fixedly connected to the rotating disk 6.

[0029] A first electric push rod 13 is fixedly connected to the bottom surface of each of the four sliding connection blocks 7. The telescopic end of the first electric push rod 13 extends to the top of the sliding connection block 7 and is fixedly connected to a lifting plate 14.

[0030] Specifically, the rotation of the output end of the first motor 11 drives the rotation of the rotating disk 6, which can precisely control the rotation angle and positioning position of the workpiece. The rotation of the output end of the second motor 10 drives the connecting rod 9. The rotation of the connecting rod 9 drives the arc-shaped slider 3 to slide inside the arc-shaped chute 2, so that the chassis 4 fixedly connected between the two arc-shaped sliders 3 rotates synchronously along the track of the arc-shaped chute 2, placing the clamped workpiece horizontally, making it more convenient to process the side surface of the workpiece. The first electric push rods 13 fixedly connected to the bottoms of the four sliding connection blocks 7 respectively push the four lifting plates 14 upward, driving the arc-shaped soft plate 16 to move synchronously, lifting the clamped workpiece, and exposing its bottom surface.

[0031] The working principle and usage process of the present utility model: Place the workpiece to be processed on the top surface of the rotating disk 6. Then, the telescopic ends of the two second electric push rods 17 installed on one side of each of the four lifting plates 14 extend and push the arc-shaped soft plate 16, so that the four arc-shaped soft plates 16 slide in the four clamping chutes 12 opened on the surface of the rotating disk 6 through the telescopic rods 15 fixedly connected to the bottoms respectively, clamping the workpiece placed on the surface of the rotating disk 6. When facing workpieces with different shapes, through the separate control of the four arc-shaped soft plates 16, and the arc-shaped soft plates 16 are respectively pushed by the two second electric push rods 17, the arc-shaped soft plates 16 will bend and deform according to the shape of the workpiece to fit the outside of the workpiece. If the outer surface of the workpiece is also uneven, through the multiple clamping small soft disks 18 installed on one side of the arc-shaped soft plate 16, it can well automatically adapt to the uneven surface of the outside of the workpiece, making the contact closer and the clamping more stable.

[0032] After the workpiece is firmly clamped, the rotation of the output end of the first motor 11 drives the rotating disk 6 to rotate. The four sliding connection blocks 7 fixedly connected to the outside of the rotating disk 6 slide inside the fixed ring 5. The rotation angle and positioning position of the workpiece are precisely controlled by the rotation of the rotating disk 6. When machining the side and bottom surfaces of the workpiece, the rotation of the output end of the second motor 10 drives the connecting rod 9. The rotation of the connecting rod 9 drives the arc-shaped slider 3 to slide inside the arc-shaped chute 2, so that the chassis 4 fixedly connected between the two arc-shaped sliders 3 rotates synchronously along the trajectory of the arc-shaped chute 2. It can rotate up to 90 degrees according to the machining requirements, and the clamped workpiece is placed horizontally, making it more convenient to machine the side surface of the workpiece. At this time, the first electric push rods 13 fixedly connected to the bottoms of the four sliding connection blocks 7 respectively push the four lifting plates 14 to move upward, driving the arc-shaped flexible plate 16 to move synchronously. The telescopic rods 15 at the bottom of the arc-shaped flexible plate 16 extend synchronously, lifting the clamped workpiece, so that its bottom surface is exposed.
