Description

A turning section is set between the two production lines to transfer the car body. At present, the existing rolling dipping systems in China are divided into electric rolling dipping conveying and mechanical rolling dipping conveying. The electric rolling dipping machine generally completes the pre-treatment and electrophoretic coating line equipment transfer through self-propelled walking or turntable; the mechanical rolling dipping realizes the transfer between the pre-treatment and electrophoretic coating line through the skid system. The existing mechanical rolling dipping turning section structure is as follows Figure 1 As shown, the line body transfer is achieved through the skid system. The pre-treatment lower part elevator separates the skid with the body from the roller dip machine, and the skid with the body is transferred to the electrophoresis conveyor line through the skid system.

[0046] It should be understood that the terms such as “having”, “including” and “comprising” used herein do not exclude the existence or addition of one or more other elements or combinations thereof.

[0047] Embodiment 1:

[0048] like Figure 2-5 As shown, the present invention provides a device for pre-treatment to electrophoresis, rolling, dipping, hanging and conveying, comprising:

[0049] A main track 1, an unpowered track 2, a friction drive device 3, a trolley group 4 and a mechanical rolling immersion vehicle 5. The main track 1 and the unpowered track 2 are both arranged in an arc shape. Multiple friction drive devices 3 and the trolley group 4 are installed on the main track 1. The friction drive device 3 is used to drive the trolley group 4 to move along the main track 1. The mechanical rolling immersion vehicle 5 is installed on the trolley group 4, and the end of the mechanical rolling immersion vehicle 5 is rollingly connected to the unpowered track 2.

[0050] The working principle and beneficial effects of the above technical solution are:

[0051] The invention provides a device for conveying from pre-treatment to electrophoresis, rolling immersion and hanging. A mechanical rolling immersion carrier 5 is installed on a trolley group 4. The trolley group 4 is carried by a main track 1 and a friction drive device 3 is installed. During the conveying operation, the friction drive device 3 is started to drive the trolley group 4 to move through the friction force. Under the guidance of the arc-shaped main track 1, the trolley group 4 turns along its shape, and the unpowered track 2 provides support for the end of the mechanical rolling immersion carrier 5.

[0052] Through the above-mentioned structural design, the mechanical rolling immersion performs friction driving on the trolley group 4 through the friction driving device 3 on the main track 1, and provides auxiliary support for the mechanical rolling immersion vehicle 5 through the unpowered track 2, so that the line body can be transferred along the track direction to ensure stable and reliable operation; compared with the existing skid system transfer method, it reduces equipment, saves costs, and reduces the difficulty of processing and maintenance, thereby improving the transfer efficiency, reducing the risks brought by the transfer, and improving the production rhythm of the production line.

[0053] Embodiment 2:

[0054] like Figure 2-5 As shown, based on the above-mentioned embodiment 1, the unpowered rails 2 are provided in two groups and are respectively supported on both sides of the support shaft 6 of the mechanical rolling immersion vehicle 5 .

[0055] The working principle and beneficial effects of the above technical solution are:

[0056] The unpowered track 2 is arranged into two groups, which can provide support to both sides of the support shaft 6 of the mechanical rolling immersion vehicle 5 at the same time, reduce the load of the trolley group 4 on the main track 1, and keep the two sides of the mechanical rolling immersion vehicle 5 balanced during movement.

[0057] Embodiment 3:

[0058] like Figure 6 , 7 As shown, based on the above embodiment 1, the friction drive device 3 includes:

[0059] A support frame 11, the support frame 11 is arranged below the main track 1;

[0060] A driving motor 12, the driving motor 12 is mounted on a motor bracket 13, and the motor bracket 13 is rotatably connected to one side of the support frame 11;

[0061] A main friction wheel 14, which is connected to the output end of the driving motor 12 and is horizontally arranged on one side above the main track 1;

[0062] The auxiliary friction wheel 15 is rotatably connected to the auxiliary friction wheel frame 16, and the auxiliary friction wheel frame 16 is rotatably connected to the motor bracket 13 and is located on the other side of the support frame 11. The auxiliary friction wheel 15 is arranged on the other side above the main track 1; when the trolley group 4 moves, it contacts the main friction wheel 14 and the auxiliary friction wheel 15 at the same time.

[0063] The working principle and beneficial effects of the above technical solution are:

[0064] When the friction drive device is in use, the trolley group 4 moves between the main friction wheel 14 and the auxiliary friction wheel 15; the drive motor 12 is started, and the drive motor 12 drives the main friction wheel 14 to rotate through the reducer, and the two sides of the trolley group 4 are respectively in contact with the main friction wheel 14 and the auxiliary friction wheel 15; under the action of the friction force between the main friction wheel 14 and one side of the trolley group 4, the trolley group 4 is driven to move; the force on the other side of the trolley group 4 is balanced through the auxiliary friction wheel 15, so that the trolley group 4 is always located in the center of the main track 1, maintaining the flexibility of the movement of the trolley group 4.

[0065] Embodiment 4:

[0066] like Figure 6 , 7 As shown, based on the above embodiment 3, the friction drive device 3 further includes:

[0067] A first tension rod 17, the first tension rod 17 is slidably connected to the support frame 11, one end of the first tension rod 17 is connected to the motor bracket 13 through a chain 18, the other end of the first tension rod 17 is sleeved with a first tension spring 19, both ends of the first tension spring 19 are respectively connected to the support frame 11 and a first adjusting nut 21, and the first adjusting nut 21 is screwed to the first tension rod 17;

[0068] The second tension rod 22 is slidably connected to the rotating sleeve 23, the rotating sleeve 23 is rotatably connected to the support frame 11, one end of the second tension rod 22 is connected to the rotating shaft of the auxiliary friction wheel frame 16 through the rotating plate 24, and the other end of the second tension rod 22 is sleeved with a second tension spring 25, both ends of the second tension spring 25 are respectively connected to the rotating sleeve 23 and the second adjusting nut 26, and the second adjusting nut 26 is threadedly connected to the second tension rod 22.

[0069] The working principle and beneficial effects of the above technical solution are:

[0070] A tensioning assembly is also provided on the friction drive device 3. When the main friction wheel 14 is tensioned and adjusted, the first adjusting nut 21 is rotated forward to bring its position close to the support frame 11, and the elastic force of the first tensioning spring 19 increases after being compressed, the pulling force of the first tensioning rod 17 on the chain 18 increases, and the tendency of the motor bracket 13 to rotate toward the center of the main track 1 increases, so that the pressure of the main friction wheel 14 on the trolley group 4 increases, thereby increasing the friction force on the trolley group 4; on the contrary, the first adjusting nut 21 is rotated reversely to move its position away from the support frame 11, and the elastic force of the first tensioning spring 19 decreases after being stretched, so that the pulling force of the first tensioning rod 17 on the chain 18 decreases, and the tendency of the motor bracket 13 to rotate toward the center of the main track 1 decreases, so that the pressure of the main friction wheel 14 on the trolley group 4 decreases, thereby reducing the friction force on the trolley group 4.

[0071] In order to keep the forces on both sides of the trolley group 4 balanced, it is necessary to tension and adjust the main friction wheel 14 and the auxiliary friction wheel 15 at the same time. When the secondary friction wheel 15 is tensioned and adjusted, the second adjusting nut 26 is rotated forward to make its position close to the rotating sleeve 23, and the elastic force of the second tensioning spring 25 is increased after being compressed. The tendency of the second tensioning rod 22 to pull the rotating plate 24 to rotate forward increases, and the tendency of the secondary friction wheel frame 16 to rotate toward the center of the main track 1 increases, which increases the pressure of the secondary friction wheel 15 on the trolley group 4, thereby increasing the friction force on the trolley group 4 and maintaining a balance with the pressure of the main friction wheel 14; on the contrary, the second adjusting nut 26 is rotated reversely to make its position away from the rotating sleeve 23, and the elastic force of the second tensioning spring 25 is reduced after being compressed, and the tendency of the second tensioning rod 22 to pull the rotating plate 24 to rotate forward decreases, so that the tendency of the secondary friction wheel frame 16 to rotate toward the center of the main track 1 is reduced, and the pressure of the secondary friction wheel 15 on the trolley group 4 is reduced, thereby reducing the friction force on the trolley group 4 and maintaining a balance with the pressure of the main friction wheel 14.

[0072] Through the above structural design, the friction wheel is tightly attached to the trolley group 4 by setting the tensioning spring, thereby ensuring the effectiveness of the friction drive; the friction force of the friction wheel on the trolley group 4 is adjusted by rotating the adjusting nut, that is, the adjustment of the friction driving force is realized, which effectively adapts to the transportation of vehicle bodies of different weights and facilitates the maintenance of the friction wheel; at the same time, the two sets of tensioning components respectively adjust the main friction wheel 14 and the auxiliary friction wheel 15, which helps to maintain the force balance on both sides of the trolley group 4.

[0073] Embodiment 5:

[0074] On the basis of the above-mentioned embodiment 3, the main friction wheel 14 and the auxiliary friction wheel 15 are both configured as rubber-covered wheels.

[0075] The working principle and beneficial effects of the above technical solution are:

[0076] The main friction wheel 14 and the auxiliary friction wheel 15 are both set as rubber-coated wheels, and the rubber-coated layer covers the surface of the friction wheel body. Its main function is to make the contact closer, increase the friction force, reduce the wear of the wheel body, and can buffer the impact to a certain extent.

[0077] Embodiment 6:

[0078] like Figure 2 As shown, on the basis of the above-mentioned embodiment 2, the main track 1 is arranged between the two groups of non-powered tracks 2, and the main track 1 is arranged close to the outer non-powered track 2, and the mechanical rolling vehicle 5 is located between the main track 1 and the inner non-powered track 2; the outer non-powered track 2 is higher than the main track 1 and the inner non-powered track 2;

[0079] The inner end of the support shaft 6 of the mechanical rolling immersion vehicle 5 is connected to a roller 7, which is rolled on the inner non-powered track 2; the outer end of the support shaft 6 is connected to a balance frame 8 and the support shaft 6 is located at the center of the balance frame 8, and the corner point of the balance frame 8 is connected to a roller 7, which is rolled on the outer non-powered track 2.

[0080] The working principle and beneficial effects of the above technical solution are:

[0081] The first arrangement of the device provides a friction driving force on the outside of the mechanical rolling and immersion vehicle 5. The specific arrangement is that the main track 1 is arranged close to the outer non-powered track 2, and the mechanical rolling and immersion vehicle 5 is located between the main track 1 and the inner non-powered track 2; the friction driving device 3 on the main track 1 provides a friction driving force from the outside of the mechanical rolling and immersion vehicle 5, thereby driving the inner mechanical rolling and immersion vehicle 5 to move; the outer non-powered track 2 is higher than the main track 1 and the inner non-powered track 2, to avoid the situation where the trolley group 4 is arranged in the middle to produce a lever effect when the heights of the two sides are the same, causing uneven force on the inner and outer non-powered tracks 2, and causing a gap between the roller 7 on one side and the non-powered track 2.

[0082] Embodiment 7:

[0083] like Figure 3 As shown, on the basis of the above-mentioned embodiment 2, the main track 1 is arranged on the inner side of the two groups of unpowered tracks 2, the mechanical rolling and soaking vehicle 5 is located between the inner and outer unpowered tracks 2, and the heights of the inner and outer unpowered tracks 2 are equal; the inner and outer ends of the support shaft 6 of the mechanical rolling and soaking vehicle 5 are connected to rollers 7, and the rollers 7 are rollingly arranged on the unpowered tracks 2.

[0084] The working principle and beneficial effects of the above technical solution are:

[0085] The second arrangement of the device provides a friction driving force on the inner side of the mechanical rolling immersion vehicle 5. Specifically, the main track 1 is arranged on the inner side of two groups of non-powered tracks 2, and the mechanical rolling immersion vehicle 5 is located between the two groups of non-powered tracks 2; the friction driving device 3 on the main track 1 provides a friction driving force from the inner side of the mechanical rolling immersion vehicle 5, thereby driving the outer mechanical rolling immersion vehicle 5 to move; this arrangement greatly shortens the length of the main track 1.

[0086] Embodiment 8:

[0087] like Figure 4As shown, on the basis of the above-mentioned embodiment 2, the main track 1 is arranged between the two groups of unpowered tracks 2, and the main track 1 is arranged close to the inner unpowered track 2, and the main track 1 and the inner unpowered track 2 each include two parallel fixed sections 31 and a rotating section 32; a turntable 9 is provided on one side of the two fixed sections 31 close to the outer unpowered track 2, and the rotating section 32 is installed on the turntable 9, and the turntable 9 rotates so that the rotating section 32 can dock with any one of the fixed sections 31.

[0088] The working principle and beneficial effects of the above technical solution are:

[0089] The third arrangement of the device is to set the main track 1 and the inner non-powered track 2 in a split form. During the transportation process, the turntable 9 first drives the rotating section 32 to rotate until it docks with the fixed section 31 on one side; under the driving action of the friction drive device 3 on the main track 1, the trolley group 4 drives the mechanical rolling and soaking vehicle 5 to move from the fixed section 31 on one side to the rotating section 32; then the turntable 9 rotates, driving the rotating section 32 and the mechanical rolling and soaking vehicle 5 to rotate until the rotating section 32 docks with the fixed section 31 on the other side, and under the driving action of the friction drive device 3 on the rotating section 32, the trolley group 4 drives the mechanical rolling and soaking vehicle 5 from the rotating section 32 on the turntable 9 to the fixed section 31 on the other side, completing the turning transportation of the mechanical rolling and soaking vehicle 5. Through the above structural design, a turntable 9 is used to realize the steering of the mechanical rolling immersion carrier 5, and a friction drive device 3 is used to realize the sending of the mechanical rolling immersion carrier 5 into and out of the turntable 9. The rotating section 32 on the turntable 9 and the fixed sections 31 on both sides can be accurately docked to ensure the stability and reliability of the conveying operation.

[0090] Embodiment 9:

[0091] like Figure 8 , 9 As shown, based on the above embodiment 1, the trolley group 4 includes:

[0092] A body 41 is provided with a shaft sleeve 42, and a support shaft 6 is installed in the shaft sleeve 42;

[0093] First slide 43, two first slides 43 are symmetrically connected to the bottom end of the vehicle body 41, and the first slide 43 is adapted to be arranged with the conveying frame 44 of the pre-treatment station and the rolling dipping station;

[0094] A second slide 45, the second slide 45 is connected to the center of the bottom end of the vehicle body 41, and the second slide 45 includes a plurality of slide short sections 46, and adjacent slide short sections 46 are hinged;

[0095] A lifting hydraulic cylinder 47, the lifting hydraulic cylinder 47 is connected to the articulation shaft of the adjacent carriage short section 46;

[0096] The lifting slider 48 is connected to the bottom end of the lifting hydraulic cylinder 47 , and the lifting slider 48 is adapted to the main track 1 .

[0097] The working principle and beneficial effects of the above technical solution are:

[0098] Two groups of slides are arranged on the trolley group 4, and the first slide 43 is arranged at the bottom of the body 41. When the trolley group 4 moves on the pre-processing station and the rolling-in station, the first slide 43 can adapt to its conveying frame 44 and move along the conveying frame 44; when the trolley group 4 moves to the main track 1, the second slide 45 is located between the main friction wheel 14 and the auxiliary friction wheel 14, and moves forward under the action of friction; the second slide 45 is arranged in the form of a combination of multiple slide short sections 46, which can be flexibly bent when the trolley group 4 turns to adapt to the curvature of the track. A lifting hydraulic cylinder 47 is arranged on the hinge shaft of the adjacent slide short section 46. When the trolley group 4 moves onto the main track 1, the lifting hydraulic cylinder 47 is started to lower the lifting slide block 48 so that it enters the main track 1 and is slidably connected thereto, thereby guiding the movement of the trolley group 4; when the trolley group 4 moves out from the main track 1, the lifting hydraulic cylinder 47 is started to raise the lifting slide block 48 without affecting the movement of the trolley group 4 on the conveying frame 44.
