Description

Technical Field

[0001] The invention relates to the technical field of conveyor belts, in particular to a conveying device for stamping parts used in special steel casting. Background Art

[0002] The conveying device is a device for conveying some product objects. It is generally used more in factories. When special steel is cast, 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;

[0003] Patent application No. CN109081046A describes a conveying device for special steel casting stamping parts, comprising a main seat and a conveying seat. Air mesh is provided on the left and right outer walls of the main seat, and chute blocks are installed on the left and right ends of the air mesh. The chute blocks are movably connected to the air mesh, and the chute blocks are welded to the main seat. A motor is fixed inside the main seat, and a movable rod is provided at the upper end of the motor. The movable rod is fixedly connected to the motor. The rear end of the main seat is connected to the conveying seat.

[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. Since the special steel castings have a large mass and inertia, there is a possibility of air leakage between the special steel castings and the suction cup due to the inertial movement. The use of conventional splints for clamping is prone to problems such as surface deformation and depression of the special steel castings during jerks. Summary of the Invention

[0005] In view of the deficiencies in the prior art, the present invention provides a conveying device for stamping parts for special steel casting, which achieves the purpose of solving the above-mentioned problems.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: A conveying device for special steel casting stamping parts, including a suspension conveying guide rail, a slider is provided inside the suspension conveying guide rail, a connector is fixedly connected to the bottom of the slider, and a conveying adsorption mechanism is provided at the bottom of the connector;

[0007] The conveying and adsorption mechanism comprises:

[0008] The fixed column is a circular disc-shaped structure. The top of the fixed column is fixedly connected to the bottom of the connector. A rotating ball is embedded in the bottom of the fixed column. The outer wall of the rotating ball is slidably connected to the inner wall of the fixed column. The fixed column is used to limit the rotating ball.

[0009] The air suction pump is fixedly connected with the bottom of the rotating ball, the bottom of the air suction pump is fixedly connected with a connecting disc, the connecting disc is a circular disc structure, the bottom of the connecting disc is fixedly connected with a suction disc, the bottom of the suction disc is provided with a steel casting part, and the air suction pump is used to control the negative pressure adsorption of the suction disc on the steel casting part.

[0010] Preferably, the inner wall of the connecting disc is provided with a first air groove, and the inner wall of the suction disc is provided with a second air groove.

[0011] Preferably, the second air groove is in communication with the first air groove, and the first air groove is in communication with the inside of the air suction pump.

[0012] Preferably, the suction disc is used to adsorb the steel casting part under negative pressure, and the connecting disc is used to connect between the air suction pump and the suction disc.

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

[0014] Preferably, the outer wall of the telescopic rod is provided with an air hole, and the inside of the telescopic rod is in communication with the outside through the air hole.

[0015] Preferably, the outer wall of the telescopic rod is fixedly connected with a push plate, and the push plate is used to push the air.

[0016] Preferably, the inner wall of the connecting disc is fixedly connected with a fixed sleeve, the inner wall of the fixed sleeve is slidably connected with a push rod, the inner wall of the fixed sleeve is provided with an embedded spring, and the inner wall of the fixed sleeve is fixedly connected with one end of the push rod through the embedded spring.

[0017] The application provides a special steel casting stamping part conveying device.

[0018] 1、The suction disc, the connecting disc and the rotating ball rotate in the inner wall of the fixed column bottom under inertia when the conveying and adsorbing mechanism is set, the rotating ball is wrapped in the inner wall of the fixed column, so that the rotating ball can slide and rotate in the inner wall of the fixed column and drive the lower steel casting part to rotate together, so that the steel casting part and the suction disc swing together to reduce the relative movement between the steel casting part and the suction disc due to inertia, thereby reducing the possibility of air leakage between the suction disc and the steel casting part and improving the stability of the suction disc in adsorbing the steel casting part under negative pressure.

[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 the connector and the slider and moves to a turn, the suction cup and the steel casting will automatically adjust their shapes through the rotation of the rotating ball to ensure that the steel casting and the suction cup always maintain an inclined state during long-distance turns. 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 the turn if conventional adsorption or clamping methods are used for transportation, and also avoiding the problem of deformation of the steel casting due to 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 adsorbing a thick suction cup and the steel casting, a tilted state will appear. This reduces the problem of uneven force and easy air leakage caused by the center of gravity of the steel casting being not centered when the suction cup and the steel casting are adsorbed. It also avoids 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 provides a limiting mechanism. When the suction cup, steel casting, and rotating ball rotate and swing, the pores on the surface of the telescopic rod have a smaller diameter, thereby limiting the speed at which the telescopic rod can extend and slide. As a result, the speed at which the connecting plate, suction cup, and steel casting rotate and swing is also limited to a certain extent, thereby providing a certain buffering force when the connector encounters a setback. At the same time, it also avoids the instability problem caused by the steel casting swinging back and forth after the setback.

[0023] 6. The present invention provides a limiting mechanism. When the suction cup is swung, the push rod in the fixed sleeve between the connecting disc and the steel casting will, under the elastic force of the built-in spring, provide a support force to the steel casting near the connecting disc, thereby reducing the angle of tilt and misalignment 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 suction cup's adsorption advantage and reducing the possibility of misalignment and falling off.

[0024] 7、The limiting mechanism is arranged, and when the suction cup just starts to adsorb the steel casting, the push rod has a certain pushing force on the steel casting, so that the adsorption between the suction cup and the steel casting is self-checked, if the adsorption is not firm, it will be directly pushed down by the push rod, avoiding the situation that the misplacement and air leakage are not discovered in time, and causing the falling problem in subsequent transportation.

[0025] 8、The limiting mechanism is arranged, when the steel casting swings, the particles attached to the surface will be taken away with the relative movement with the surrounding air, and will be thrown out with the centrifugal force of the swing, the angle of the telescopic rod will change during the swing, so that the stirring plate of the outer wall will stir the air, and the air flow is further used to promote the falling of the particles on the surface of the steel casting, avoiding the problem that the steel casting is affected by the quality of the large amount of dust particles attached in the factory during long time transportation.

DETAILED DESCRIPTION

[0037] Embodiment one: please refer to Figures 1-4 The application provides a kind of technical scheme: a kind of stamping part conveying device for special steel casting, including hanging conveying guide rail 1, hanging conveying guide rail 1 inside is provided with slider 2, slider 2 bottom is fixedly connected with connector 5, and connector 5 bottom is provided with conveying adsorption mechanism 3;

[0038] Conveying adsorption mechanism 3 includes:

[0039] Fixed column 301, fixed column 301 is circular disc structure, and the top of fixed column 301 is fixedly connected with the bottom of connector 5, and rotating ball 302 is embedded in the bottom of fixed column 301, and the outer wall of rotating ball 302 is slidably connected with the inner wall of fixed column 301, and fixed column 301 is used to limit rotating ball 302;

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

[0041] In use, the steel casting 7 to be hung and conveyed is placed below the suction disc 305, then the hanging conveying guide rail 1 is started to control the slider 2 to drive the connector 5 to move and align the top of the steel casting 7 below, the air pump 303 is started, the air in the suction disc 305 is pumped away through the first air groove 306 and the second air groove 307 in the connecting disc 304 and the suction disc 305, thereby completing the negative pressure adsorption of the steel casting 7 by the suction disc 305, and then the hanging and conveying work of the steel casting 7 is completed by the hanging conveying guide rail 1 controlling the slider 2 and the connector 5;

[0042] When transporting the steel casting 7 for a long distance, stopping or starting and accelerating will all cause jerk, once the jerk occurs, the steel casting 7 will move relative to the suction disc 305 due to inertia to a certain extent, since the mass of the steel casting 7 is large, the inertia is also large, and the suction disc 305 is a deformable material, at this time, the steel casting 7 and the suction disc 305 will have the possibility of air leakage due to the inertia of mutual motion.

[0043] Embodiment two: please refer to Figures 1-9 On the basis of embodiment one, the application provides a technical solution: the inner wall of the connecting disc 304 is provided with a first air groove 306, and the inner wall of the suction disc 305 is provided with a second air groove 307. The first air groove 306 and the second air groove 307 play a role in communicating air.

[0044] The inside of the second air groove 307 is in communication with the inside of the first air groove 306, and the inside of the first air groove 306 is in communication with the inside of the air pump 303. The air pump 303 is used to play a role in pumping away the air inside the suction disc 305 through the first air groove 306 and the second air groove 307.

[0045] The suction disc 305 is used to play a role in negative pressure adsorbing the steel casting 7, and the connecting disc 304 is used to play a role in connecting between the air pump 303 and the suction disc 305.

[0046] At this time, the suction disc 305, the connecting disc 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 disc 305 swing together to reduce the relative movement between the steel casting 7 and the suction disc 305 due to inertia, thereby reducing the possibility of air leakage between the suction disc 305 and the steel casting 7 and improving the stability of the suction disc 305 in negative pressure adsorbing the steel casting 7.

[0047] When the jerk occurs, the rotating ball 302, the air pump 303, the connecting disc 304, the suction disc 305 and the steel casting 7 will rotate and swing together to release the jerk impact force, and the relative movement trend between the steel casting 7 and the suction disc 305 will be converted into the movement trend of the steel casting 7 moving away from the suction disc 305 in the direction away from the rotating center of the rotating ball 302 under the centrifugal swing of the suction disc 305. Under this movement trend, the suction disc 305 can greatly reduce the risk of air leakage caused by the horizontal movement between the suction disc 305 and the steel casting 7. The steel casting 7 can effectively play the uniform negative pressure adsorption effect of the suction disc 305 on the steel casting 7 in the state of moving vertically away from the suction disc 305, thereby ensuring the stable adsorption effect of the suction disc 305 on the steel casting 7 and reducing the risk of falling off.

[0048] When the object is adsorbed on the connector 5 and the slider 2 moves, when encountering a turn or the like, the steel casting 7 below the suction cup 305 will be subjected to a centrifugal force away from the center of the turn when turning, at which time the suction cup 305 and the steel casting 7 will automatically adjust their shape through the rotation of the rotating ball 302 to maintain the inclined state of the steel casting 7 and the suction cup 305 during long-distance turning, and use the adsorption force of the suction cup 305 on the steel casting 7 in the vertical adsorption state to resist the centrifugal force at this time, thereby avoiding the problem of uneven stress between the steel casting 7 and the clamp caused by the centrifugal force during turning if a conventional adsorption or clamping mode is used, and avoiding the problem of deformation of the steel casting 7 under uneven stress, which affects the quality of the steel casting 7;

[0049] And when the steel casting 7 is adsorbed, even if the clamping position of the steel casting 7 and the suction cup 305 is not adjusted, the steel casting 7 will also rotate the suction cup 305 and the rotating ball 302 above it, and the center of gravity will be automatically maintained in the center, so that the suction cup 305 and the steel casting 7 are in an inclined state, reducing the problem of uneven stress caused by the off-center gravity of the steel casting 7 during adsorption of the suction cup 305 and the steel casting 7, and avoiding the problem of deformation of the steel casting 7 caused by uneven adsorption, and the possibility of clamping and falling off;

[0050] Embodiment three: please refer to Figures 1-10 On the basis of embodiment one and embodiment two, the application provides a technical solution: the outer wall of the fixed column 301 is provided with a limiting mechanism 4, the limiting mechanism 4 includes a first rotating ball 401, the first rotating ball 401 is rotatably connected to the outer wall of the fixed column 301, a telescopic rod 402 is fixedly connected to the outer wall of the first rotating ball 401, one end of the telescopic rod 402 is fixedly connected with 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 disc 304.

[0051] The outer wall of the telescopic rod 402 is provided with an air hole 407, and the inside of the telescopic rod 402 is in communication with the outside through the air hole 407.

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

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

[0054] When the suction disc 305, the steel casting 7 and the rotating ball 302 rotate and swing, the telescopic rod 402 articulated between the fixed column 301 and the connecting disc 304 and the second rotating ball 403 will change in length, the telescopic rod 402 is provided with air holes 407 on the surface, when the suction disc 305 and the connecting disc 304 rotate, the telescopic rod 402 between the connecting disc 304 and the fixed column 301 is squeezed and stretched, the air holes 407 on the surface of the telescopic rod 402 are small in caliber, thereby limiting the speed of the telescopic sliding of the telescopic rod 402, and then the speed of the rotation and swing of the connecting disc 304, the suction disc 305 and the steel casting 7 is limited to a certain extent, thereby giving the connector 5 a certain buffering degree when encountering a jerk, and the instability problem caused by the back and forth swing of the steel casting 7 after the jerk is avoided.

[0055] Meanwhile, when swinging, since the suction disc 305 is of soft material, the suction disc 305 and the steel casting 7 below will tilt to a certain extent, changing from a horizontal state to an inclined state, thereby the push rod 406 in the fixed sleeve 405 between the connecting disc 304 and the steel casting 7 will support the position of the steel casting 7 close to the connecting disc 304 under the elastic force of the built-in spring, reducing the tilting displacement angle between the suction disc 305 and the steel casting 7, and trying to ensure the parallel state between the suction disc 305 and the steel casting 7, thereby maximizing the advantage of the suction of the suction disc 305 and reducing the possibility of the dislocation and falling of the suction disc 305.

[0056] And when the suction disc 305 starts to suck the steel casting 7, since the push rod 406 has a certain pushing force on the steel casting 7, the suction between the suction disc 305 and the steel casting 7 will be self-checked, if the suction is not firm, the suction disc 305 will be directly pushed down by the push rod 406, avoiding the situation that the dislocation and air leakage are not discovered in time and causing the falling problem in subsequent transportation.

[0057] When the steel casting 7 swings, the particles attached to the surface will be taken away by the relative movement with the surrounding air, and will be thrown out by the centrifugal force of the swing, and when swinging, the angle of the telescopic rod 402 will change, thereby driving the air with the driving plate 404 on the outer wall, and further improving the falling of the particles on the surface of the steel casting 7 by using air flow, avoiding the problem that the quality of the steel casting 7 is affected by the attachment of a large amount of dust particles in the factory during long-time transportation.

[0058] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this, any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
