[0002] Rotating components are important elements for mechanical rotation. They are of various types and complex structures. They are widely used in various mechanical equipment. They transmit power and torque in different ways to realize the rotation of mechanical parts. By rotating or moving the rotating components, the rotating components can realize multi-angle rotation. The application range of rotating components is very wide. For example, by rotating the rotating components, the workpiece being processed can be transferred from one station to another, reducing the trouble of manual handling and improving production efficiency.

[0003] For example, when deburring mechanical parts, in order to save overall steps, some parts of different specifications are placed together for deburring.

[0014] Preferably, the receiving device comprises a receiving plate, a first support rod and a second support rod, the bottom of the receiving plate is rotatably connected to a support shaft, and the first support rod is elastically connected to an elastic limiting rod inside;

[0015] The supporting shaft, the first supporting rod and the second supporting rod are all fixedly connected to the supporting seat, the position of the receiving plate corresponds to the lower pressure plate and is in conflict with the lower pressure plate, the end of the receiving plate away from the lower pressure plate is in conflict with the second supporting rod and the discharge conveyor belt, a spherical buffer head is provided on the top of the elastic limiting rod, the elastic limiting rod is in conflict with the receiving plate, and the receiving plate can be flipped with the supporting shaft as the axis.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] like Figures 1 to 8 As shown, the present invention provides a high degree of freedom rotating assembly, including a support seat 1, a rotating device 2 is arranged on the top of the support seat 1, a receiving device 3 and a discharge conveyor belt 5 are distributed in an annular shape on the outer side of the rotating device 2, and a feed conveyor belt 4 is arranged on the top of the rotating device 2;

[0032] The rotating device 2 includes a limiting mechanism 21 , a supporting mechanism 22 is slidably connected inside the limiting mechanism 21 , a platform 23 is movably connected to the top of the supporting mechanism 22 , and an adjusting mechanism 24 is distributed in a ring shape outside the limiting mechanism 21 .

[0033] The above scheme is adopted: the parts are conveyed to the top of the platform 23 by the feeding conveyor belt 4, and the platform 23 is directly pressed down a certain distance by the deadweight of the parts. At the same time, the adjustment mechanism 24 is slightly bent in all directions, and the plunger 222 and the oil cylinder 223 are pressed downward by the platform 23 until they stop moving. At this time, the oil port 224 at the corresponding position is connected with the oil channel 214, so that the oil inside the oil cylinder 223 can enter the sub-base 212 through the oil port 224 and the oil channel 214, and then the oil port 224 pushes the oil cylinder 223 to move upward and reset, so that the oil inside the oil cylinder 223 Through the squeezing of the plunger 222, the oil enters the sub-base 212 from the oil port 224 and the oil channel 214. After entering the sub-base 212, the oil squeezes and pushes the limit piston 242 to move downward, causing the limit piston 242 to pull the first sliding rod 241 and the elastic connecting rod 244 to move downward, and then the platform 23 will rotate in the corresponding direction, allowing the parts to enter the receiving plate 31 at the corresponding position, so that after the parts are transported to the top of the platform 23, they can be accurately and quickly classified and transported, and the model of the first spring 225 can be adjusted to accommodate the classification of parts of different weights.

[0034] like Figure 2 , Figure 3 and Figure 4 As shown, the limiting mechanism 21 includes a main base 211, the lower end of the main base 211 is fixedly connected to a secondary base 212 in a ring-shaped arrangement, a limiting channel 213 is provided inside the main base 211, and an oil channel 214 is provided inside the main base 211; the secondary base 212 is interconnected with the limiting channel 213 through the oil channel 214, the limiting channels 213 correspond to the positions of the secondary bases 212 respectively, the oil channel 214 is spirally distributed inside the main base 211, and a limiting ring is provided inside the limiting channel 213.

[0035] The above scheme is adopted: by setting a limit mechanism 21, the limit mechanism 21 supports the supporting mechanism 22, the platform 23 and the adjusting mechanism 24, and through the secondary base 212 set on the outside of the main base 211, the adjusting mechanism 24 can be separated from the platform 23 and slide up and down, the limit channel 213 opened inside the main base 211 corresponds to the position of the secondary base 212, and the limit channel 213 is connected with the oil channel 214 through the oil channel 214, so that the up and down movement of the adjusting mechanism 24 inside the main base 211 is controlled by the up and down movement of the platform 23, and the limit ring set inside the limit channel 213 is used to limit the upward sliding distance of the oil cylinder 223, so that after the oil cylinder 223 is reset, the platform 23 continues to rise under the push of the adjusting mechanism 24, and at the same time the platform 23 pulls the main support frame 221 to reset.

[0036] like Figure 3 , Figure 5 and Figure 6As shown, the support mechanism 22 includes a main support frame 221, a plunger 222 is fixedly connected to the bottom of the main support frame 221, an oil cylinder 223 is sleeved at the bottom of the plunger 222, an oil port 224 is opened on the outer side of the oil cylinder 223, and a first spring 225 is fixedly connected to the bottom of the oil cylinder 223; a spherical connector is arranged on the top of the main support frame 221, the main support frame 221 is slidably connected to the main base 211, the plunger 222 is annularly distributed at the bottom of the main support frame 221, and the oil cylinder 223 corresponds to the internal position of the limit channel 213 and is slidably connected to the limit channel 213. The oil port 224 is inside the position channel 213, and the oil port 224 corresponds to the vertical position of the oil channel 214. The diameter of the oil port 224 is greater than that of the oil channel 214, and the oil ports 224 are tangent to each other in the horizontal direction; the platform 23 is concentric with the main base 211, and one end of the feed conveyor belt 4 is located at the center of the platform 23. The bottom of the platform 23 and the top of the main support frame 221 are connected by a spherical connector. The feed conveyor belt 4 is used to transport parts to the top of the platform 23. The connection between the spherical connector and the platform 23 enables the platform 23 to rotate freely within a certain range.

[0037] The above scheme is adopted: by setting a supporting mechanism 22, the supporting mechanism 22 supports the main body of the platform 23, and at the same time, by squeezing the oil in the oil cylinder 223 to control the movement of the adjustment mechanism 24, the spherical connector set on the top of the main support frame 221 is rotatably connected to the platform 23, so that the platform 23 can be deflected at multiple angles on the top of the main support frame 221 to achieve high-degree-of-freedom rotation. At the same time, due to the setting of the adjustment mechanism 24, after the parts are placed on the platform 23, the platform 23 will directly squeeze the main support frame 221 to descend, and will not be directly turned over due to the downward pressure of the parts. The design of the plunger 222 and the oil cylinder 223 can play the role of a hydraulic push rod by the sliding of the plunger 222 in the oil cylinder 223. The oil port 224 opened on the outer side of the oil cylinder 223 is arranged to be spirally distributed with the oil port 224 and the oil channel 214, and the oil port 224 is arranged to be tangent to each other in the horizontal direction, so that the oil The liquid port 224 will be connected with the corresponding oil channel 214 within the moving range, so that no matter how far the main support frame 221 stays and is pressed down, there will always be an oil port 224 connected with its corresponding oil channel 214, so that the oil inside the oil cylinder 223 will be transported to the corresponding secondary base 212 to push the plunger 222 to move downward. The first spring 225 arranged at the bottom of the oil cylinder 223 is used to push the oil cylinder 223 to reset. At the same time, after the oil channel 214 is connected with the oil port 224, the oil cylinder 223 can be pushed to move upward, so as to push the oil cylinder 223 upward, so that the oil inside the oil cylinder 223 is squeezed into the secondary base 212, and the platform 23 is pulled by the adjustment mechanism 24 to rotate. The setting of the oil port 224 and the oil channel 214 enables the platform 23 to be connected with the oil port 224 and the oil channel 214 at different positions, and rotate in different directions, and has a high degree of rotation freedom.

[0038] like Figure 3 , Figure 4 and Figure 6 As shown, the direction adjustment mechanism 24 includes a first sliding rod 241, the bottom of the first sliding rod 241 is fixedly connected to a limiting piston 242, the bottom of the limiting piston 242 is fixedly connected to a second spring 243, and the upper end of the first sliding rod 241 is hinged to an elastic connecting rod 244; the first sliding rod 241 passes through the top of the secondary base 212 and is slidably connected to the inside of the secondary base 212, the limiting piston 242 is located on the lower side of the oil channel 214, the bottom of the second spring 243 is fixedly connected to the main base 211, and the top of the elastic connecting rod 244 is rotatably connected to the platform 23.

[0039] The above scheme is adopted: by setting the adjustment mechanism 24, the adjustment mechanism 24 supports the platform 23, so that the platform 23 remains stable, and at the same time, the platform 23 can be pulled to rotate to one side. By setting the first sliding rod 241, the first sliding rod 241 is slidably connected with the secondary base 212 to keep the first sliding rod 241 stable. The limiting piston 242 sliding inside the secondary base 212, which is set at the bottom of the first sliding rod 241, can be aligned with the oil channel 214 and the oil port 224 and the oil inside the oil cylinder 223 is squeezed into the secondary base 212. At this time, the oil will fill the secondary base 212 and push the limiting piston 242 downward, so that the limiting piston 242 pulls the elastic connecting rod 244 through the first sliding rod 241. The limiting piston 242 is located at the lower side of the oil channel 214, the bottom of the second spring 243 is fixedly connected to the main base 211, and the top of the elastic connecting rod 244 is rotatably connected to the platform 23.

[0040] like Figure 1 Figure 7 and Figure 8 As shown, the receiving device 3 includes a receiving plate 31, a first support rod 33 and a second support rod 35. The bottom of the receiving plate 31 is rotatably connected to a support shaft 32, and the first support rod 33 is elastically connected to an elastic limiting rod 34; the supporting shaft 32, the first support rod 33 and the second support rod 35 are all fixedly connected to the support seat 1, the position of the receiving plate 31 corresponds to the lower pressure plate 25 and contacts the lower pressure plate 25, the end of the receiving plate 31 away from the lower pressure plate 25 contacts the second support rod 35 and the discharge conveyor belt 5, a spherical buffer head is provided on the top of the elastic limiting rod 34, the elastic limiting rod 34 contacts the receiving plate 31, and the receiving plate 31 can be flipped with the supporting shaft 32 as the axis.

[0041] The above scheme is adopted: by setting the receiving device 3, the receiving plate 31 receives the parts that slide down after the platform 23 rotates, and transports the parts to the discharging conveyor belt 5, and the receiving plate 31 receives the parts, and baffles tightened inwardly are provided on both sides of the top of the receiving plate 31, which can accurately transport the parts to the discharging conveyor belt 5, and the receiving plate 31 will conflict with the lower pressure plate 25 when the platform 23 rotates, and be squeezed and turned downward by the lower pressure plate 25. When the parts on the top of the platform 23 slide to the top of the receiving plate 31, the elastic limiting rod 34 compressed at the bottom of the receiving plate 31 will push the receiving plate 31 to return to its original position. At the same time, the receiving plate 31 will push the platform 23 in the opposite direction through the lower pressure plate 25 so that the platform 23 can be quickly reset. The setting of the second support rod 35 at the bottom of the receiving plate 31 can support the receiving plate 31, and can also prevent the receiving plate 31 from hitting the discharging conveyor belt 5 and causing damage after it turns over.

[0042] like Figures 2 to 8As shown, the feed conveyor belt 4 conveys the parts to the top of the platform 23. The parts on the platform 23 will sink a certain distance due to the downward pressure of gravity. The corresponding oil port 224 is connected to the oil channel 214 according to the downward pressure distance, and then the oil port 224 pushes the oil cylinder 223 to move upward and reset, so that the oil inside the oil cylinder 223 is squeezed by the plunger 222, and the oil enters the sub-base 212 from the oil port 224 and the oil channel 214, and then the oil pushes the limit piston 242 to move downward, so that the limit piston 242 pulls the first sliding rod 241 to move downward, so that the platform 23 rotates in the corresponding direction.

[0043] The above scheme is adopted: when the feed conveyor belt 4 conveys the parts to the top of the platform 23, the platform 23 will be directly pressed downward by the parts, so that the platform 23 will sink directly for a certain distance, and at the same time, the adjustment mechanism 24 will be slightly bent to the surroundings. After the platform 23 is stable, the oil port 224 at the corresponding position will be connected with the oil channel 214 according to the downward pressing distance, and then the oil port 224 pushes the oil cylinder 223 to move upward and reset, so that the oil inside the oil cylinder 223 is squeezed by the plunger 222, so that the oil enters the sub-base 212 from the oil port 224 and the oil channel 214. Because the space inside the oil cylinder 223 is much larger than the single sub-base 212, after the oil enters the sub-base 212, it squeezes and pushes the limit piston 242 to move downward, so that the limit piston 242 pulls the first sliding rod 241 and the elastic connecting rod 244 to move downward, so that the platform 23 rotates in the corresponding direction.

[0044] The working principle and use process of the present invention are as follows: during operation, the parts are conveyed to the top of the platform 23 through the feeding conveyor belt 4, so that the platform 23 is directly pressed downward by the parts, and the platform 23 directly sinks a certain distance, and at the same time, the adjustment mechanism 24 is slightly bent in all directions, and the platform 23 squeezes the plunger 222 and the oil cylinder 223 to move downward synchronously. After the platform 23 is no longer sinking, the oil port 224 at the corresponding position is connected with the oil channel 214, so that the oil cylinder 223 and the secondary base 212 can exchange the oil in and out, and the oil port 224 pushes the oil cylinder 223 to move upward and reset, so that the oil inside the oil cylinder 223 is affected The extrusion of the plunger 222 causes the oil to enter the sub-base 212 from the oil port 224 and the oil channel 214. Because the space inside the oil cylinder 223 is much larger than that of a single sub-base 212, after the oil enters the sub-base 212, it squeezes and pushes the limit piston 242 to move downward, causing the limit piston 242 to pull the first sliding rod 241 and the elastic connecting rod 244 to move downward, and then the platform 23 will rotate in the corresponding direction, so that the parts enter the receiving plate 31 at the corresponding position. The platform 23 can rotate in different directions after the parts of different weights press the platform 23 to move different distances, so that the platform 23 can rotate with a high degree of freedom;

[0045] When the parts enter the receiving plate 31, the receiving plate 31 will be reset under the push of the elastic limiting rod 34, and the parts will slide to the discharge conveyor belt 5. At the same time, the receiving plate 31 pushes the platform 23 to reset through the lower pressure plate 25, so that the platform 23 pulls the first sliding rod 241 and the limiting piston 242 upward through the elastic connecting rod 244, so that the oil inside the secondary base 212 is transported back to the oil cylinder 223. At the same time, the first spring 225 pushes the oil cylinder 223 and the plunger 222 to reset, thereby pushing the platform 23 to return to a stable state, so as to classify the parts.
