Description

Technical Field

[0002] The conveying device is a device for conveying some product objects. It is generally used more in factories. When casting special steel, a conveying device is needed to convey its stamping parts. When conveying, efficiency is more important, and the integrity of the stamping parts should also be guaranteed;

[0004] When transporting special steel castings over long distances, jerks will occur when stopping, starting, and accelerating. Once a jerk occurs, the special steel casting will, to a certain extent, move relative to the suction cup due to its own inertia.

If conventional clamping is used, it is easy to cause problems such as surface deformation and depression of the special steel casting during jerks. Summary of the invention

[0010] Preferably, a first air groove is formed on the inner wall of the connection plate, and a second air groove is formed on the inner wall of the suction cup, and the first air groove and the second air groove serve to connect the air.

[0011] Preferably, the interior of the second air groove is connected to the interior of the first air groove, and the interior of the first air groove is connected to the interior of an air pump, and the air pump is used to extract the air inside the suction cup through the first air groove and the second air groove.

[0012] Preferably, the suction cup is used to perform the function of negative pressure adsorption of the steel casting, and the connecting plate is used to perform the function of connection between the vacuum pump and the suction cup.

[0013] Preferably, a limiting mechanism is provided on the outer wall of the fixed column, and the limiting mechanism includes a first rotating ball, which is rotatably connected to the outer wall of the fixed column, and the outer wall of the first rotating ball is fixedly connected to a telescopic rod, and one end of the telescopic rod is fixedly connected to a second rotating ball, and the outer wall of the second rotating ball is rotatably connected to the outer wall of the connecting plate.

[0014] Preferably, an air hole is formed on the outer wall of the telescopic rod, and the interior of the telescopic rod is connected to the outside through the air hole.

[0015] Preferably, a toggle plate is fixedly connected to the outer wall of the telescopic rod, and the toggle plate is used to play a role in toggling air.

[0016] Preferably, a fixing sleeve is fixedly connected to the inner wall of the connecting disk, a push rod is slidably connected to the inner wall of the fixing sleeve, a built-in spring is provided on the inner wall of the fixing sleeve, and the inner wall of the fixing sleeve is fixedly connected to one end of the push rod via the built-in spring.

[0017] The present invention provides a conveying device for stamping parts for special steel casting, which has the following beneficial effects:

[0018] 1. The present invention is provided with a conveying and adsorption mechanism. When there is a setback, the suction cup, the connecting plate and the rotating ball will rotate together with inertia in the inner wall at the bottom of the fixed column. The inner wall of the fixed column will wrap the rotating ball, so that the rotating ball can slide and rotate in the inner wall of the fixed column, and drive the steel casting below to rotate together, so that the steel casting and the suction cup can swing together, so as to reduce the relative movement between the steel casting and the suction cup due to inertia, thereby reducing the possibility of air leakage between the suction cup and the steel casting, and improving the stability of the suction cup negative pressure adsorption of the steel casting.

[0019] 2. The present invention provides a conveying and adsorption mechanism. When a setback occurs, the suction cup and the steel casting will rotate and swing together to release the impact force of the setback. Under this movement trend, the risk of air leakage caused by lateral movement between the steel casting and the steel casting will be greatly reduced. When the steel casting moves vertically away from the suction cup, the suction cup can effectively exert a uniform negative pressure adsorption effect on the steel casting, thereby ensuring the stable adsorption of the steel casting by the suction cup and reducing the risk of falling off.

[0020] 3. The present invention provides a conveying and adsorption mechanism. When an object is adsorbed on a connector and a slider and moves through a turn, the suction cup and the steel casting will automatically adjust their shapes through the rotation of the rotating ball, so that the steel casting and the suction cup always maintain an inclined state during a long turn. The suction force of the suction cup on the steel casting in a vertical adsorption state is used to counteract the centrifugal separation force at this time, thereby avoiding the problem of uneven force between the steel casting and the clamper under the centrifugal action of a turn if conventional adsorption or clamping methods are used for transportation, and also avoiding the problem of deformation of the steel casting under uneven force, which affects its own quality.

[0021] 4. The present invention provides a conveying and adsorption mechanism. When the steel casting is adsorbed, even if the clamping position of the steel casting and the center of the suction cup is not adjusted, the steel casting will drive the suction cup and the rotating ball above to rotate, and will automatically maintain the center of gravity in the center. Therefore, when the suction cup and the steel casting are adsorbed, a tilted state will appear, thereby reducing the problem of uneven force and easy air leakage caused by the center of gravity of the steel casting not being centered when the suction cup and the steel casting are adsorbed, and also avoiding the problem of the steel casting being deformed due to uneven adsorption, and the possibility of the clamping falling off.

[0022] 5. The present invention sets a limiting mechanism. When the suction cup, the steel casting and the rotating ball rotate and swing, the pores on the surface of the telescopic rod have smaller diameters, thereby limiting the telescopic sliding speed of the telescopic rod. Then, the rotation and swinging speeds of the connecting plate, the suction cup and the steel casting are limited to a certain extent, thereby providing a certain buffering force for the connector when encountering setbacks, and also avoiding the instability problem caused by the steel casting swinging back and forth after the setback.

[0023] 6. The present invention sets a limiting mechanism. When the connection plate and the steel casting are swung, the push rod in the fixed sleeve between the connection plate and the steel casting will support the steel casting near the connection plate under the elastic force of the built-in spring, thereby reducing the tilt and misalignment angle between the suction cup and the steel casting, and ensuring the parallel state between the suction cup and the steel casting as much as possible, thereby maximizing the advantages of the suction cup adsorption and reducing the possibility of its misalignment and falling off.

[0024] 7. The present invention sets a limiting mechanism, and when the suction cup just starts to adsorb the steel casting, the push rod has a certain thrust on the steel casting, which will cause a self-check of the adsorption between the suction cup and the steel casting. If the adsorption is not strong, it will be directly pushed down by the push rod, avoiding the problem of adsorption misalignment and leakage not being discovered in time, which will lead to the problem of falling off in subsequent transportation.

[0025] 8. The present invention sets a limiting mechanism, and when the steel casting swings, it will move relative to the surrounding air as it swings, and the particles attached to the surface will be taken away and thrown out with the centrifugal force of the swing. When swinging, the angle of the telescopic rod will change, thereby driving the paddle plate on the outer wall to paddle the air, and the air flow will be used to further enhance the removal of particles on the surface of the steel casting, thereby avoiding the problem that the steel casting is attached with a large amount of dust particles in the factory during long-term transportation, thereby affecting its own quality.

DETAILED DESCRIPTION

[0037] Example 1: Please refer to Figure 1-4 The present invention provides a technical solution: a conveying device for stamping parts for special steel casting, comprising a suspension conveying rail 1, a slider 2 is arranged inside the suspension conveying rail 1, a connector 5 is fixedly connected to the bottom of the slider 2, and a conveying adsorption mechanism 3 is arranged at the bottom of the connector 5;

[0038] The conveying and adsorption mechanism 3 comprises:

[0039] The fixed column 301 is a circular disc-shaped structure. The top of the fixed column 301 is fixedly connected to the bottom of the connector 5. A rotating ball 302 is embedded in the bottom of the fixed column 301. The outer wall of the rotating ball 302 is slidably connected to the inner wall of the fixed column 301. The fixed column 301 is used to limit the rotating ball 302.

[0040] The air pump 303, the top of the air pump 303 is fixedly connected to the bottom of the rotating ball 302, the bottom of the air pump 303 is fixedly connected to a connecting plate 304, the connecting plate 304 is a circular disc structure, the bottom of the connecting plate 304 is fixedly connected to a suction cup 305, the bottom of the suction cup 305 is provided with a steel casting 7, and the air pump 303 is used to control the suction cup 305 to absorb the steel casting 7 under negative pressure;

[0041] When in use, the steel casting 7 to be suspended and transported is placed under the suction cup 305, and then the suspension conveying guide rail 1 is started to control the slider 2 to drive the connector 5 to move and align with the top of the steel casting 7 below, and the vacuum pump 303 is started to remove the negative pressure of the air inside the suction cup 305 through the connecting plate 304 and the first air groove 306 and the second air groove 307 in the suction cup 305, so as to complete the negative pressure adsorption of the steel casting 7 by the suction cup 305, and then the suspension conveying guide rail 1 controls the slider 2 and the connector 5 to complete the lifting belt-shaped transportation work;

[0042] When transporting the steel casting 7 over a long distance, there will be setbacks when stopping, starting, or accelerating. Once setbacks occur, the steel casting 7 will to a certain extent move relative to the suction cup 305 due to its own inertia. Since the mass of the steel casting 7 is large, the inertia is also large, and the suction cup 305 is a deformable material. At this time, there is a possibility of air leakage between the steel casting 7 and the suction cup 305 due to the inertia of the mutual movement;

[0043] Example 2: Please refer to Figure 1-9 On the basis of the first embodiment, the present invention provides a technical solution: a first air groove 306 is provided on the inner wall of the connection disk 304, and a second air groove 307 is provided on the inner wall of the suction cup 305. The first air groove 306 and the second air groove 307 play a role in air communication.

[0044] The interior of the second air groove 307 is connected to the interior of the first air groove 306 , and the interior of the first air groove 306 is connected to the interior of the air pump 303 . The air pump 303 is used to extract the air inside the suction cup 305 through the first air groove 306 and the second air groove 307 .

[0045] The suction cup 305 is used to absorb the steel casting 7 by negative pressure, and the connecting plate 304 is used to connect the air pump 303 and the suction cup 305;

[0046] At this time, when the suction cup 305, the connecting plate 304 and the rotating ball 302 will rotate together in the inner wall at the bottom of the fixed column 301 due to inertia, and the inner wall of the fixed column 301 will wrap the rotating ball 302, so that the rotating ball 302 can slide and rotate in the inner wall of the fixed column 301, and drive the steel casting 7 below to rotate together, so that the steel casting 7 and the suction cup 305 swing together, so as to reduce the relative movement between the steel casting 7 and the suction cup 305 due to inertia, thereby reducing the possibility of air leakage between the suction cup 305 and the steel casting 7, and improving the stability of the suction cup 305 adsorbing the steel casting 7 with negative pressure;

[0047] When setback occurs, the rotating ball 302, the air pump 303, the connecting plate 304, the suction cup 305 and the steel casting 7 will rotate and swing together to release the impact force of the setback, and the lateral relative movement trend between the steel casting 7 and the suction cup 305 will be converted into a movement trend of the steel casting 7 away from the rotation center of the rotating ball 302 and away from the suction cup 305 under the centrifugal swing of the suction cup 305. Under this movement trend, the suction cup 305 will greatly reduce the risk of air leakage caused by the lateral movement between the steel casting 7 and the suction cup 305. When the steel casting 7 moves vertically away from the suction cup 305, the suction cup 305 can effectively exert a uniform negative pressure adsorption effect on the steel casting 7, thereby ensuring the stable adsorption of the steel casting 7 by the suction cup 305 and reducing the risk of falling off.

[0048] When the object is adsorbed on the connector 5 and the slider 2 and moves, when encountering a turn or the like, the steel casting 7 under the suction cup 305 will be subjected to a centrifugal force away from the center of the bend when turning. At this time, the suction cup 305 and the steel casting 7 will automatically adjust their shapes through the rotation of the rotating ball 302 to achieve that the steel casting 7 and the suction cup 305 always maintain an inclined state during a long-distance turn, and the suction force of the suction cup 305 on the steel casting 7 in a vertical adsorption state is used to counteract the centrifugal separation force at this time, thereby avoiding the problem of uneven force between the steel casting 7 and the clamper under the centrifugal action of the turn if conventional adsorption or clamping methods are used for transportation, and also avoiding the problem of deformation of the steel casting 7 under the condition of uneven force, which affects its own quality;

[0049] Furthermore, when the steel casting 7 is adsorbed, even if the clamping position of the steel casting 7 and the center of the suction cup 305 is not adjusted, the steel casting 7 will also drive the suction cup 305 and the rotating ball 302 above to rotate, and will automatically maintain the center of gravity in the middle, so that the suction cup 305 and the steel casting 7 will be tilted when adsorbed, reducing the problem of uneven force and easy air leakage caused by the center of gravity of the steel casting 7 not being centered when the suction cup 305 and the steel casting 7 are adsorbed, and also avoiding the problem of deformation of the steel casting 7 due to uneven adsorption, and the possibility of clamping and falling off;

[0050] Example 3: Please refer to Figure 1-10 On the basis of the first and second embodiments, the present invention provides a technical solution: a limiting mechanism 4 is provided on the outer wall of the fixed column 301, and the limiting mechanism 4 includes a first rotating ball 401, and the first rotating ball 401 is rotatably connected to the outer wall of the fixed column 301, and the outer wall of the first rotating ball 401 is fixedly connected to a telescopic rod 402, and one end of the telescopic rod 402 is fixedly connected to a second rotating ball 403, and the outer wall of the second rotating ball 403 is rotatably connected to the outer wall of the connecting plate 304.

[0051] An air hole 407 is formed on the outer wall of the telescopic rod 402 , and the interior of the telescopic rod 402 is connected to the outside through the air hole 407 .

[0052] The outer wall of the telescopic rod 402 is fixedly connected with a toggle plate 404, and the toggle plate 404 is used to play the role of toggle air.

[0053] The inner wall of the connecting plate 304 is fixedly connected with a fixing sleeve 405, the inner wall of the fixing sleeve 405 is slidably connected with a push rod 406, the inner wall of the fixing sleeve 405 is provided with an internal spring, and the inner wall of the fixing sleeve 405 is fixedly connected with one end of the push rod 406 through the internal spring;

[0054] When the suction cup 305, the steel casting 7, and the rotating ball 302 rotate and swing, the telescopic rod 402 and the second rotating ball 403 hinged between the fixed column 301 and the connecting plate 304 will change their lengths, and the telescopic rod 402 is provided with air holes 407. When the suction cup 305 and the connecting plate 304 rotate, the telescopic rod 402 between the connecting plate 304 and the fixed column 301 will be squeezed and stretched, and the air holes 407 provided on the surface of the telescopic rod 402 have a small diameter, thereby limiting the telescopic sliding speed of the telescopic rod 402. Then, the speed of the connecting plate 304, the suction cup 305, and the steel casting 7 rotating and swinging is limited to a certain extent, thereby providing a certain buffering force to the connector 5 when encountering setbacks, and also avoiding the instability problem caused by the steel casting 7 swinging back and forth after the setbacks.

[0055] At the same time, when swinging, since the suction cup 305 is made of soft material, the suction cup 305 and the steel casting 7 below will be tilted to a certain extent, and will change from a horizontal state to an inclined state, so that the push rod 406 in the fixing sleeve 405 between the connecting plate 304 and the steel casting 7 will, under the elastic force of the built-in spring, provide a support force to the position of the steel casting 7 close to the connecting plate 304, thereby reducing the tilt and misalignment angle between the suction cup 305 and the steel casting 7, and ensuring the parallel state between the suction cup 305 and the steel casting 7 as much as possible, thereby maximizing the advantage of the suction cup 305 adsorption and reducing the possibility of its misalignment and falling off;

[0056] And when the suction cup 305 just starts to adsorb the steel casting 7, since the push rod 406 has a certain thrust on the steel casting 7, the adsorption between the suction cup 305 and the steel casting 7 will be self-checked. If the adsorption is not strong, it will be directly pushed down by the push rod 406, avoiding the problem of adsorption misalignment and leakage not being discovered in time, which will cause the problem of falling off during subsequent transportation.

[0057] When the steel casting 7 swings, it will move relative to the surrounding air, and the particles attached to the surface will be taken away and thrown out due to the centrifugal force of the swing. At the same time, when swinging, the angle of the telescopic rod 402 will change, thereby driving the paddle plate 404 on the outer wall to paddle the air, and using the air flow to further enhance the removal of particles on the surface of the steel casting 7, thereby avoiding the problem that the steel casting 7 is attached with a large amount of dust particles in the factory during long-term transportation and affects its own quality.

[0058] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
