Description

Technical Field

[0001] This utility model relates to the field of pipe fitting processing technology, specifically an automatic feeding device for processing metal pipe fittings. Background Technology

[0002] When metal pipes are processed in an automated manner, a robotic arm is needed to grip the metal pipes at a designated position. To achieve automated processing, a feeding device needs to be set up at the designated position so that the robotic gripper can grip the pipes at the designated position. However, the metal pipes in the feeding device are usually piled up together, and the outlet below the feed port is in an inclined state. This can easily cause two pipes to press against each other in an inclined position to form a balance state, thus preventing the pipes from falling to the designated position and affecting the feeding. Furthermore, when the pipes reach the designated position, they need to slide and roll down. This sliding can easily cause positional deviation, making it easy for the gripper to grip the pipes in different positions, which can lead to inaccurate positioning in subsequent automated processing. Utility Model Content

[0003] This invention provides an automatic feeding device for processing metal pipe fittings, which overcomes the shortcomings described in the background art.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] An automatic feeding device for processing metal pipe fittings includes a feeding box, a feeding port, and a limiting mechanism. The feeding port and the limiting mechanism are located at the upper end of the feeding box, and the feeding port is located to the right of the limiting mechanism.

[0006] The limiting mechanism includes a first hydraulic actuator, a movable mechanism, a push plate, an elastic plate, and a positioning mechanism. The push plate is located at the output end of the first hydraulic actuator, and the first hydraulic actuator hydraulically pushes the push plate to move vertically. The movable mechanism is located inside the feed inlet. The elastic plate is located inside the feed box. A spring is horizontally arranged on the side of the elastic plate. The metal tube falls from the outlet end of the feed inlet onto the elastic plate and presses against one end of the spring. The spring elastically pushes the metal tube to the upper end of the push plate. The positioning mechanism is located at the upper end of the feed box. The push plate moves vertically and squeezes the movable mechanism. The movable mechanism squeezes the side of the metal tube inside the feed inlet.

[0007] A preferred technical solution: The movable mechanism includes a fixed plate, a shaking mechanism, a rotating rod, a rubber block, a force-bearing block, and a spring rod. The force-bearing block and the fixed plate are respectively attached to the left and right sides of the rubber block. The left and right ends of the spring rod are connected to the force-bearing block and the rotating rod. There are two spring rods, symmetrically arranged on both sides of the fixed plate. The rotating rod is divided into inner and outer rings, with a spring between them. The inner ring of the rotating rod is fixed inside the fixed plate. When the spring rod is under force, it presses against the outer ring of the rotating rod and compresses the spring. There are two shaking mechanisms, symmetrically arranged on the outer ring of the rotating rod. When the spring rod is stationary, the outer ring of the rotating rod is elastically reset by the spring, causing the outer ring of the rotating rod to drive the shaking mechanism to rotate back and forth. The shaking mechanism rubs against the side of the metal pipe inside the feed port.

[0008] A preferred technical solution: The shaking mechanism includes a connecting rod, a spring, a circular block, and a plastic block. The spring is located on the side of the connecting rod, and a circular block is located at the outer end of the spring. The surface of the circular block is covered with irregularly distributed plastic blocks. When the connecting rod rotates, it causes the plastic blocks on the surface of the circular block to rub against the side of the metal pipe and to squeeze the side of the pipe under the elasticity of the spring.

[0009] A preferred technical solution: The positioning mechanism includes a laser sensor, a second hydraulic actuator, a hollow tube, a connector, a blocking block, and a plastic block. The laser sensor is mounted on two parallel hollow tubes. Two second hydraulic actuators are mounted on both sides of the laser sensor. A connector connected to the output end of the second hydraulic actuator is disposed inside the hollow tube. An electrical signal drives the second hydraulic actuator to extend and retract the connector. A notch is provided on one side of the hollow tube. The connector and the plastic block are connected through the notch. The plastic block moves parallel to the outside of the hollow tube and pushes the pipe fitting to move between the two hollow tubes. The blocking block is disposed between the two hollow tubes, and the lower side of the pipe fitting abuts against the blocking block.

[0010] A preferred technical solution: A trapezoidal plate is provided at the upper end of the feed box, with the inclined surface of the trapezoid located at the top, and the metal pipe slides into the middle of the positioning mechanism from the inclined surface of the trapezoid.

[0011] Compared with existing technologies, this technical solution has the following advantages:

[0012] In this invention, the force-bearing block compresses the spring rod, which drives the outer ring of the rotating rod to rotate. At this time, the outer ring of the rotating rod rotates elastically through the spring while being fixed by the inner ring of the rotating rod. The outer ring of the rotating rod drives the shaking mechanism to rotate back and forth. The rotation of the shaking mechanism causes the connecting rod to drive the spring to rub against the side of the metal pipe in the feed port. Under the elasticity of the spring, the plastic block rubs irregularly against the side of the pipe, causing the two pipes that are mutually pressing and balanced in the feed port to become unbalanced and fall down, preventing the pipes from pressing against each other in the feed port and getting stuck, thus preventing them from falling down.

[0013] In this invention, after the metal pipe falls between two hollow pipes, it is detected by the laser sensor, which then drives the second hydraulic device to extend and retract the connector, causing the connector to slide inside the hollow pipe and drive the plastic block to push the metal pipe against the blocking block. At this time, the metal pipe reaches the designated gripping position, avoiding inaccurate processing caused by the pipe being gripped in an unstable position. Attached Figure Description

[0023] like Figures 1 to 5 As shown in the figure, this utility model proposes an automatic feeding device for processing metal pipe fittings. Its structure includes a feeding box 1, a feeding port 2 and a limiting mechanism 3. The feeding port 2 and the limiting mechanism 3 are located at the upper end of the feeding box 1, and the feeding port 2 is located to the right of the limiting mechanism 3.

[0024] The limiting mechanism 3 includes a first hydraulic unit 31, a movable mechanism 32, a push plate 33, an elastic plate 34, and a positioning mechanism 35. The push plate 33 is located at the output end of the first hydraulic unit 31, and the first hydraulic unit 31 hydraulically pushes the push plate 33 to move vertically. The movable mechanism 32 is located inside the feed inlet 2. The elastic plate 34 is located inside the feed box 1. A spring is horizontally arranged on the side of the elastic plate 34. The metal tube falls from the outlet end of the feed inlet 2 onto the elastic plate 34 and presses against one end of the spring. The spring elastically pushes the metal tube to the upper end of the push plate 33. The positioning mechanism 35 is located at the upper end of the feed box 1. The push plate 33 moves vertically and squeezes the movable mechanism 32. The movable mechanism 32 squeezes the side of the metal tube inside the feed inlet 2.

[0025] Furthermore, when the push plate 33 is stationary, its uppermost position is to the side of the elastic plate 34, and there is a space about the size of a metal tube above the push plate 33.

[0026] The movable mechanism 32 includes a fixed plate 321, a shaking mechanism 322, a rotating rod 323, a rubber block 324, a force-bearing block 325, and a spring rod 326. The force-bearing block 325 and the fixed plate 321 are respectively attached to the left and right sides of the rubber block 324. The left and right ends of the spring rod 326 are connected to the force-bearing block 325 and the rotating rod 323. Two spring rods 326 are provided and symmetrically arranged on both sides of the fixed plate 321. The rotating rod 323 is divided into inner and outer rings, with the inner and outer rings connected... A spring is provided, and the inner ring of the rotating rod 323 is fixedly installed inside the fixed plate 321. When the spring rod 326 is under force, the spring rod 326 presses the outer ring of the rotating rod 323 and compresses the spring. Two shaking mechanisms 322 are provided and are symmetrically arranged on the outer ring of the rotating rod 323. When the spring rod 326 is stationary, the outer ring of the rotating rod 323 is elastically reset by the spring, and the outer ring of the rotating rod 323 drives the shaking mechanism 322 to rotate back and forth. The shaking mechanism 322 rubs against the side of the metal pipe in the feed port 2.

[0027] Furthermore, the moving mechanism 32 is in a horizontal state, and the two shaking mechanisms 322 inside the moving mechanism 32 rotate back and forth at an angle of 30°. The side of the shaking mechanism 322 corresponds exactly to the inclined position of the lower half of the inside of the feed port 2.

[0028] The shaking mechanism 322 includes a connecting rod 3221, a spring 3222, a circular block 3223, and a plastic block 3224. The spring 3222 is located on the side of the connecting rod 3221. The outer end of the spring 3222 is provided with a circular block 3223. The surface of the circular block 3223 is provided with irregularly distributed plastic blocks 3224. When the connecting rod 3221 rotates, it causes the plastic blocks 3224 on the surface of the circular block 3223 to rub against the side of the metal pipe and to squeeze the side of the pipe under the elasticity of the spring 3222.

[0029] Furthermore, the diameter of the circular block 3223 is larger than the diameter of the metal pipe fitting to prevent the circular block 3223 from entering the middle of the metal pipe fitting.

[0030] In this invention, the metal pipe is placed at the feed inlet 2 and slides into the elastic plate 34. Under the spring force of the elastic plate 34, the slid-in metal pipe is bounced onto the upper end of the push plate 33. This causes an electrical signal to drive the first hydraulic actuator 31 to push the push plate 33, moving the metal pipe to the right of the positioning mechanism 35. At this point, the metal pipe slides from the inclined side of the push plate 33 onto the trapezoidal block at the upper end of the feed box 1 and is guided to fall into the positioning mechanism 35. After the laser sensor 351 in the positioning mechanism 35 senses the metal pipe, the push plate 33 extends and retracts downwards to reset. During the extension and retraction of the push plate 33, it presses against the force block 325 inside the feed inlet 2, causing... The force-bearing block 325 moves elastically, thus squeezing the spring rod 326. The spring rod 326 drives the outer ring of the rotating rod 323 to rotate. At this time, the outer ring of the rotating rod 323 rotates elastically through the spring under the fixation of the inner ring of the rotating rod 323. The outer ring of the rotating rod 323 drives the shaking mechanism 322 to rotate back and forth. At this time, the rotation of the shaking mechanism 322 causes the connecting rod 3221 to drive the spring 3222 to rub against the side of the metal pipe in the feed port 2. Under the elasticity of the spring 3222, the plastic block 3224 rubs irregularly against the side of the pipe, causing the two pipes that are mutually pressing and balanced in the feed port 2 to become unbalanced and fall, preventing the pipes from pressing against each other in the feed port 2 and getting stuck, thus preventing them from falling.

[0031] The positioning mechanism 35 includes a laser sensor 351, a second hydraulic actuator 352, a hollow tube 353, a connector 354, a blocking block 355, and a plastic block 356. The laser sensor 351 is mounted on two parallel hollow tubes 353. Two second hydraulic actuators 352 are mounted on both sides of the laser sensor 351. A connector 354 is installed inside the hollow tube 353 and connected to the output end of the second hydraulic actuator 352. An electrical signal drives the second hydraulic actuator 352 to extend or retract the connector 354. A notch is provided on one side of the hollow tube 353, and the connector 354 and the plastic block 356 are connected through the notch. The plastic block 356 moves parallel to the outside of the hollow tube 353 and pushes the tube to move between the two hollow tubes 353. The blocking block 355 is located between the two hollow tubes 353, and the lower side of the tube abuts against the blocking block 355.

[0032] Furthermore, a trapezoidal plate is provided at the upper end of the feed box 1, with the inclined surface of the trapezoid located at the top, and the metal pipe slides into the middle of the positioning mechanism 35 from the inclined surface of the trapezoid.

[0033] Furthermore, the laser sensor 351 is surrounded by a housing, which is fixed to the hollow tube 353. The second hydraulic actuator 352 extends and retracts inside the hollow tube 353. The direction of the laser sensor 351 is parallel to the two hollow tubes 353. When the laser sensor 351 cannot detect the metal pipe, the electrical signal drives the first hydraulic actuator 31 to extend and retract again.

[0034] In this invention, after the metal pipe falls between the two hollow tubes 353, it is detected by the laser sensor 351, which then drives the second hydraulic device 352 to extend and retract the connector 354, causing the connector 354 to slide inside the hollow tube 353. This causes the plastic block 356 to push the metal pipe against the blocking block 355, at which point the metal pipe reaches the designated gripping position, thus avoiding inaccurate processing caused by the pipe's position not being fixed when it is gripped.

[0035] The above description is merely a preferred embodiment of this utility model, and therefore cannot be used to limit the scope of this utility model. All equivalent changes and modifications made in accordance with the scope of this utility model and the contents of the specification should still fall within the scope of this utility model.
