[0004] Therefore, based on the above retrieval and in combination with the existing ones, during the part conveying process, it is difficult to avoid vibrations and collisions, resulting in problems such as part damage, deformation, or surface scratches. However, this patent cannot buffer the parts during transportation, making it difficult to reduce the impact force on the parts, thereby affecting the integrity and surface quality of the parts. At the same time, the device cannot achieve conveying at different angles and directions, making it easy for the parts to shake and shift during transportation, and it is difficult to meet the requirements of vertical lifting or lowering conveying. Summary of the Invention

[0005] The purpose of the present invention is to provide a conveying device for mechanical parts with adjustable stroke to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A conveying device for mechanical parts with adjustable stroke, including a bottom plate and a bracket, the bracket is fixedly installed on the top surface of the bottom plate, a pipeline for transporting mechanical parts is slidably installed inside the bracket cavity, the pipeline adopts a double-layer folding structure, and a keel for supporting the pipeline is installed between the two layers of pipelines. The pipeline is a silicone hose, and the mechanical parts are wrapped by the pipeline to ensure that the conveyed parts pass through the pipeline safely and reliably, reducing the risk of damage and collision;

[0007] An outer wall of the pipeline is sleeved with a driving structure for driving the pipeline to rotate and an adjusting structure for adjusting a transmission angle. A driving wheel of the driving structure can drive the pipeline to rotate, and a suction cup of the adjusting structure can adjust a transportation stroke of the pipeline.

The suction cup is fixedly connected to a bottom surface of the arc-shaped plate, and the suction cup is used for adsorbing and fixing the outer layer pipeline.

[0009] As a further solution of the present invention, in order to enable the suction cup to adsorb and fix the pipeline while moving, a spring pipe is slidably connected to an inner cavity of the special-shaped plate. One end of the spring pipe is fixedly connected to the sliding pipe, and the other end of the spring pipe is fixedly connected to a limit block for positioning the spring pipe, and the limit block is fixedly connected to an inner wall of the special-shaped plate.

[0010] As a further solution of the present invention, an auxiliary wheel for assisting the movement of the sliding pipe is rotatably connected to an outer wall of one end of the sliding pipe through a bearing, and the auxiliary wheel is located inside the special-shaped plate. A moving groove for providing sliding of the sliding pipe is formed in an outer wall of the special-shaped plate, and the sliding pipe is located in the moving groove.

[0011] As a further solution of the present invention, the keel is composed of two sections, and a telescopic pipe for cooperating with the contraction and folding of the pipeline is fixedly connected between the two sections of the keel through bolts. When the pipeline contracts and folds, the two sections of the keel are pulled to move relatively, so that the telescopic pipe contracts and folds accordingly.

[0012] As a further solution of the present invention, a blowing pump I for adjusting an inner diameter of pipeline transportation is fixedly installed on an outer wall of the outer cover pipe, and a control valve for adjusting an inflation state inside the pipeline is fixedly installed at a bottom end of the outer wall of the pipeline.

[0013] As a further solution of the present invention, a feed pipe is fixedly connected to one side of a group of the brackets. A guiding hopper and a blowing pump II are respectively fixedly installed at two ends of the feed pipe. The blowing pump II is used for pushing parts, and the guiding hopper is used for guiding the parts into the pipeline. An injection pipe for injecting parts is fixedly connected to a top end of the feed pipe.

[0014] As a further solution of the present invention, the driving structure includes a fixed cover, the fixed cover is sleeved on the outer wall of the outer layer pipeline, and a plurality of driving wheels are provided and all rotatably installed inside the fixed cover. The pipeline is driven by the plurality of driving wheels to achieve interlayer conversion rotation. Each driving wheel is slidably attached to the outer wall of the outer layer pipeline, and a plurality of silica gel anti-slip strips are fixedly installed on the outer wall of each driving wheel. The driving wheel controls the pipeline to rotate for interlayer conversion around the keel, so that the pipeline always wraps the parts during the transportation of the parts, realizing basic fixation and protection, preventing random movement during transportation, and reducing the risk of collision damage.

[0015] As a further solution of the present invention, a toothed ring for driving the driving wheel to rotate is rotatably installed in the inner cavity of the fixed cover, and the driving wheel is rotatably sleeved outside the toothed ring. A gear groove is opened in the inner cavity of the driving wheel, and the toothed ring is engaged with the gear groove through a toothed block fixedly connected to its outer wall.

[0016] As a further solution of the present invention, the bottom surface of the bottom plate is rotatably connected to the base through a bearing, and the two are rotatably connected through an electric push rod. The electric push rod is used to change the conveying angle of the device, and both ends of the electric push rod are fixedly connected to the bottom plate and the base respectively through connecting pieces.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. When the present invention is used, through the silica gel pipeline, by virtue of the good flexibility and elasticity of silica gel itself, it can easily adapt to various shapes of mechanical parts. During the transportation of parts, the silica gel material can, by virtue of its own elastic deformation, wrap the parts in all directions, effectively reducing the damage, deformation and surface scratching risks caused by vibration and collision during transportation. Moreover, the inflated pipeline can play a good clamping and fixing role for the parts, effectively reducing the gap between the pipeline and the parts. When the device needs to carry out transportation operations at a special angle (such as vertical transportation), it can still ensure the stability of part transportation and avoid the situation of part falling off. At the same time, silica gel is a non-toxic, odorless and chemically stable material, which will not corrode or pollute the transported mechanical parts, effectively guaranteeing the quality and performance of the parts;

[0019] 2. When the present invention is used, by setting the adjusting structure, the conveying stroke length of the pipeline can be accurately changed. By means of the suction cup to adsorb and pull the pipeline, the conveying distance can be flexibly adjusted according to actual needs, greatly improving the applicability of the device. At the same time, by setting the driving structure in cooperation with the keel, it is ensured that the pipeline can rotate stably and efficiently, prompting the originally outer part to gradually move inward. By using a special rotation method, the pipeline always wraps the parts during the transportation of the parts, effectively reducing the possibility of collision and displacement, and guaranteeing the integrity of the parts and the stability of the transportation process;

[0020] 3. When the present invention is in use, through the cooperation of the air blowing pump I and the control valve, the expansion degree of the inner layer pipeline can be accurately controlled according to the result sensed by the sensor, so as to adapt to parts of different sizes, increase the use value of the device. At the same time, the electric push rod can control the conveying angle of the device, which can meet the conveying requirements of different angles and directions, and effectively expand the application range of the device.

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] Embodiment 1: Please refer to Figures 1 to 5 , a conveying device for a travel-adjustable mechanical part, including a bottom plate 1 and a bracket 2. The bracket 2 is fixedly installed on the top surface of the bottom plate 1. A pipeline 3 for transmitting mechanical parts is slidably installed in the inner cavity of the bracket 2. The pipeline 3 adopts a double-layer folding structure, and a keel 4 for supporting the pipeline 3 is installed between the two layers of the pipeline 3. The pipeline 3 is a silica gel hose. The mechanical part is wrapped by the pipeline 3 to ensure that the conveyed part safely and reliably passes through the pipeline 3, reducing the risk of damage and collision.

[0032] A driving structure 5 for driving the pipeline 3 to rotate and an adjusting structure 6 for adjusting the transmission angle are sleeved on the outer wall of the pipeline 3. The driving wheel 502 of the driving structure 5 can drive the pipeline 3 to rotate, and the suction cup 605 of the adjusting structure 6 can adjust the transportation stroke of the pipeline 3.

[0033] Specifically, there are two groups of brackets 2, which are respectively located at both ends of the pipeline 3. Magnetic rings 8 are fixedly sleeved on the outer walls of the keels 4. Electromagnets are arranged inside the inner walls of the brackets 2. The brackets 2 are magnetically connected to the magnetic rings 8 through the electromagnets. The flexible pipeline 3 can be stably fixed by the brackets 2, so as to ensure that the pipeline 3 maintains a stable position during operation. And when in use, the fixing force between the brackets 2 and the magnetic rings 8 can be accurately controlled by adjusting the current of the electromagnets, so as to avoid the pipeline 3 being unable to work properly due to being too tight or too loose, and further realize the stable fixing of the pipeline 3. At the same time, while ensuring the fixing effect by the magnetic rings 8, it does not affect the interlayer conversion rotation of the pipeline 3 around the keel 4, ensuring that the device can not only operate stably but also has a flexible conveying function.

[0034] The adjusting structure 6 includes an outer cover pipe 601, which is sleeved on the outer wall of the outer layer pipeline 3. A plurality of special-shaped plates 602 (the specific shape is referred to Figure 4 ) are fixedly connected to the inner cavity of the outer cover pipe 601. A sliding pipe 603 is slidably connected to the inner cavity of each special-shaped plate 602. An arc-shaped plate 604 is fixedly connected to the bottom end of the sliding pipe 603. The suction cup 605 is fixedly connected to the bottom surface of the arc-shaped plate 604, and the suction cup 605 is used for adsorbing and fixing the outer layer pipeline 3.

[0035] Specifically, there are two groups of six arc-shaped plates 604 and suction cups 605 each, which are arranged in groups to achieve full circumferential wrapping of the pipeline 3, ensuring the stability of adsorbing and pulling the pipeline 3. The two groups of suction cups 605 respectively adsorb and fix the outer pipeline 3 and pull it to both sides, so as to achieve the purpose of shrinking the pipeline 3, thereby changing the overall conveying length of the pipeline 3. The bottom end of the special-shaped plate 602 is provided with a protruding plate, which can limit and squeeze the pulled pipeline 3. At the same time, the bottom end of the sliding pipe 603 penetrates through the arc-shaped plate 604 and is connected to the top end of the suction cup 605;

[0036] In order to enable the suction cup 605 to adsorb and fix the pipeline 3 while moving, a spring tube 606 is slidably connected to the inner cavity of the special-shaped plate 602. One end of the spring tube 606 is fixedly connected to the sliding tube 603, and the other end of the spring tube 606 is fixedly connected with a limit block 607 for positioning the spring tube 606, and the limit block 607 is fixedly connected to the inner wall of the special-shaped plate 602;

[0037] Specifically, an air suction cavity is formed in the inner cavity of the special-shaped plate 602. The top end of the special-shaped plate 602 is fixedly connected with an air suction pipe 608, and the bottom end of the air suction pipe 608 is communicated with the air suction cavity. A circular hole groove is formed at the center of the limit block 607, and a silica gel sleeve for preventing gas leakage is fixedly sleeved on the outer wall of the limit block 607. When the air in the air suction cavity of the special-shaped plate 602 is sucked through the air suction pipe 608, a strong suction force will be generated. This suction force will be conducted to the suction cup 605 through the spring tube 606 and the sliding tube 603 in sequence, so that the air pressure inside the suction cup 605 rapidly decreases. Under the action of the air pressure difference, the suction cup 605 can firmly adsorb and fix the pipeline 3. At the same time, relying on the foldable characteristic of the spring tube 606, when the spring tube 606 is affected by the suction force, it will move and contract in the direction of the limit block 607, thereby pulling the connected sliding tube 603 and suction cup 605 to move together, enabling the suction cup 605 to apply a pulling force to the pipeline 3 and achieving the expected purpose of pulling the pipeline 3;

[0038] One end of the outer wall of the sliding tube 603 is rotatably connected with an auxiliary wheel 609 for assisting the movement of the sliding tube 603 through a bearing, and the auxiliary wheel 609 is located inside the special-shaped plate 602. A moving groove for providing sliding of the sliding tube 603 is formed on the outer wall of the special-shaped plate 602, and the sliding tube 603 is located in the moving groove;

[0039] Specifically, the auxiliary wheel 609 is slidably installed in the air suction cavity, and the shape of the air suction cavity is used to make the auxiliary wheel 609 drive the suction cup 605 to move upward first and then move to both sides, further increasing the foldable storage range of the pipeline 3;

[0040] An air suction pump 610 for providing suction force is fixedly installed on the upper surface of the outer cover tube 601 through bolts, and the suction ends of the air suction pump 610 are respectively fixedly connected with the air suction pipes 608 through connecting pipes;

[0041] The keel 4 is composed of two sections, and a telescopic tube 611 for cooperating with the retractable and foldable pipeline 3 is fixedly connected between the two sections of the keel 4 by bolts. When the pipeline 3 is retracted and folded, the two sections of the keel 4 are pulled to move relative to each other, causing the telescopic tube 611 to contract and fold accordingly.

[0042] Embodiment 2: Please refer to Figure 2 、 Figure 5 , a conveying device for a travel-adjustable mechanical part, which is different from that of Embodiment 1 in that a first air blowing pump 7 for adjusting the conveying inner diameter of the pipeline 3 is fixedly installed on the outer wall of the outer cover tube 601, and a control valve 9 for adjusting the inflation state inside the pipeline 3 is fixedly installed at the bottom end of the outer wall of the pipeline 3;

[0043] Specifically, there are two control valves 9 in total. An electromagnetic ring is provided at the bottom end of one of the control valves 9 and is magnetically connected to the first air blowing pump 7 through the electromagnetic ring. This control valve 9 is set as a one-way intake valve, and the first air blowing pump 7 is connected to the one-way intake valve to inject gas into the pipeline 3, causing the inner layer of the pipeline 3 to bulge and fit the part, so as to adapt to parts of different sizes. The other control valve 9 is set as a one-way exhaust valve. When it is necessary to release the air inside the pipeline 3, the one-way exhaust valve is manually opened to deflate, ensuring that the inner diameter adjustment of the pipeline 3 can flexibly adapt to the size change of the part;

[0044] More specifically, with the help of the control valve 9, it can ensure that the pipeline 3 is in a connected state with the first air blowing pump 7 without interfering with the interlayer conversion rotation of the pipeline 3 itself. After the first air blowing pump 7 and the control valve 9 are connected, gas is injected into the pipeline 3. At the same time, a ventilation groove is provided inside the keel 4, so that the injected gas can flow more smoothly. Under the push of the gas, the inner pipeline 3 gradually arches, thereby changing the inner diameter range available for conveying inside the pipeline 3, and can play a role in wrapping and limiting the parts being conveyed.

[0045] Please refer to Figure 1 、 Figure 2 、 Figure 6 , one side of a group of brackets 2 is fixedly connected with a feed pipe 10. A guiding hopper 11 and a second air blowing pump 12 are respectively fixedly installed at both ends of the feed pipe 10. The second air blowing pump 12 is used to push the part, and cooperate with the guiding hopper 11 to guide the part into the pipeline 3. The top end of the feed pipe 10 is fixedly connected with an injection pipe 13 for injecting the part;

[0046] Specifically, the guiding hopper 11 restricts the expansion at the inlet of the pipeline 3. The second air blowing pump 12 is used to blow the part into the pipeline 3 to prevent the part from being blocked or staying during the conveying process. In order to prevent the part from colliding with the inner wall of the feed pipe 10 when entering the feed pipe 10, a silica gel soft pad 14 is fixedly installed on the inner wall of the feed pipe 10.

[0047] Embodiment 3: Please refer toFigure 1 , Figure 2 , Figure 7 , a conveying device for a stroke-adjustable mechanical part, which is different from that of Embodiment 1 in that the driving structure 5 includes a fixed cover 501 sleeved on the outer wall of the outer layer pipe 3. A plurality of driving wheels 502 are provided and are all rotatably installed inside the fixed cover 501. The pipe 3 is driven by the plurality of driving wheels 502 to realize interlayer conversion rotation. Each group of driving wheels 502 is slidably attached to the outer wall of the outer layer pipe 3, and a plurality of silica gel anti-slip strips are fixedly installed on the outer wall of each group of driving wheels 502. The driving wheels 502 control the pipe 3 to rotate for interlayer conversion around the keel 4, so that the pipe 3 always wraps the part during the transportation of the part, realizing basic fixation and protection, preventing random movement during transportation, and reducing the risk of collision damage;

[0048] Specifically, clamping plates 503 for limiting the position of the driving wheels 502 are attached to both sides of each group of driving wheels 502, and the clamping plates 503 are fixedly connected to the inner wall of the fixed cover 501;

[0049] A toothed ring 504 for driving the driving wheels 502 to rotate is rotatably installed in the inner cavity of the fixed cover 501, and the driving wheels 502 are rotatably sleeved outside the toothed ring 504. A gear groove is formed in the inner cavity of the driving wheels 502, and the toothed ring 504 is meshed with the gear groove through a tooth block fixedly connected to its outer wall;

[0050] Specifically, the gear groove is provided with a certain inclination angle to be adapted to mesh with the tooth blocks of the rotating toothed ring 504. A motor 505 is fixedly installed on the outer wall of the fixed cover 501. A sawtooth gear 506 for driving the toothed ring 504 to rotate is fixedly installed on the output shaft of the motor 505. A sawtooth groove is formed in the outer wall of the toothed ring 504, and the sawtooth groove is meshed with the sawtooth gear 506;

[0051] More specifically, starting the output shaft of the motor 505 drives the sawtooth gear 506 to rotate. The sawtooth gear 506 is meshed with the sawtooth groove on the outer wall of the toothed ring 504, so as to drive the toothed ring 504 to drive the driving wheels 502 to rotate around the toothed ring 504. By virtue of the sliding fit between the silica gel anti-slip strips on the outer wall of the driving wheels 502 and the outer wall of the outer layer pipe 3, and by virtue of the increased friction force, the driving wheels 502 drive the outer layer pipe 3 to rotate for interlayer conversion.

[0052] Please refer to Figure 8 , the bottom surface of the bottom plate 1 is rotatably connected to a base 15 through a bearing, and the two are rotatably connected through an electric push rod 16. The electric push rod 16 is used to change the conveying angle of the device, and both ends of the electric push rod 16 are fixedly connected to the bottom plate 1 and the base 15 respectively through connecting pieces.

[0053] The working principle of the present invention is:

[0054] First, the operator injects mechanical parts into the feed pipe 10 through the injection pipe 13. The silica gel soft pad 14 can prevent the parts from colliding. The second air blowing pump 12 is started to blow the parts to move into the pipe 3, and the guide hopper 11 is used to guide the parts to smoothly enter the pipe 3;

[0055] Then, after the parts enter the pipe 3, the motor 505 is started. Its output shaft drives the saw gear 506 to rotate. The saw gear 506 drives the toothed ring 504 to rotate. The toothed ring 504 drives the driving wheel 502 to rotate around the toothed ring 504. The silica gel anti-slip strips on the outer wall of the driving wheel 502 slide and fit with the outer wall of the outer pipe 3. With the increased friction, the outer pipe 3 is driven to rotate layer by layer around the keel 4 in the direction of the feed pipe 10, prompting the originally outer pipe 3 to gradually move inward, so that the pipe 3 always wraps the parts during the transportation process, reducing the risk of collision damage;

[0056] At the same time, as the pipe 3 rotates, after the first air blowing pump 7 is connected to the control valve 9, the first air blowing pump 7 injects gas into the pipe 3. The air flow is used to push the inner pipe 3 to arch, changing the inner diameter range available for transportation inside it, playing a role in wrapping and limiting the transported parts. At the same time, the sensor in the pipe 3 senses the contact tightness between the inner pipe 3 and the parts, and controls the first air blowing pump 7 according to the sensing result to ensure that the inner pipe 3 expands moderately, making the inner diameter of the pipe 3 for transportation smaller than the outer diameter of the transported parts, so as to play a good clamping and limiting role for the parts;

[0057] Finally, the suction pump 610 is started. The air in the suction cavity of the special-shaped plate 602 is sucked through the suction pipe 608. The generated suction force is conducted to the suction cup 605 through the spring tube 606 and the sliding tube 603, reducing the air pressure inside the suction cup 605 to adsorb and fix the outer pipe 3. At the same time, the spring tube 606 moves and contracts in the direction of the limit block 607 under the suction force, pulling the sliding tube 603 and the suction cup 605 to move, so that the auxiliary wheel 609 slides in the suction cavity of the special-shaped plate 602, driving the suction cup 605 to move up first and then move to both sides. Because the two suction cups 605 respectively adsorb and pull the outer pipe 3 to both sides, when the pipe 3 contracts, it pulls the two keels 4 to move relatively, and the telescopic tube 611 contracts and folds accordingly, effectively realizing the contraction of the pipe 3 and changing its overall transportation length;

[0058] Secondly, by controlling the expansion and contraction of the electric push rod 16, the angle between the bottom plate 1 and the base 15 is changed, thereby adjusting the transportation angle of the entire transportation device to meet the requirements of different transportation angles.

[0059] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent replacements or changes, and should be covered within the protection scope of the present invention.
