Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing technology, specifically to a liftable and adjustable main roller bed. Background Technology

[0002] In automotive manufacturing production lines, mainline roller beds are commonly used to transport vehicle frames or other components. However, traditional mainline roller beds typically have a fixed height. In actual production, this fixed-height roller bed presents several inconveniences. For example, on automotive assembly lines, different car models have different chassis heights, and a fixed-height roller bed may not be able to adequately meet the transport and assembly needs of various models. Furthermore, traditional mainline roller beds can only transport materials in one direction, resulting in poor transport efficiency. Moreover, during transport, the mainline roller bed cannot be adjusted for materials of different sizes, which can easily lead to material shifting during transport and affect subsequent processing. To solve these problems, a height-adjustable mainline roller bed is needed.

[0003] The existing mainline roller bed has problems such as not being able to adjust the height, not being able to transport materials at multiple angles, and not being able to correct deviations during the material transport process to ensure the stability of the materials. Therefore, there is an urgent need for a mainline roller bed that can be adjusted in height. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a height-adjustable main roller bed to solve the problems of existing main roller beds being unable to adjust height, unable to transport materials at multiple angles, and unable to correct deviations during material transport to ensure material stability.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a height-adjustable main roller bed, including a track frame, a connecting rod installed at the bottom of the track frame, a fixed platform installed on the outer wall of the connecting rod, a rotary motor installed at the bottom of the fixed platform, a turntable installed at the top of the rotary motor, a sliding sleeve installed on the side wall of the turntable, and rollers installed on the inner wall of the sliding sleeve.

[0006] An electric lifting rod is installed on the top of the turntable, a power motor is installed on the side wall of the electric lifting rod, a limit sleeve is installed on the top of the sliding sleeve, a limit rod is installed on the inner wall of the limit sleeve, a conveyor frame is installed on the top of the limit rod, a drive motor is installed on the side wall of the conveyor frame, and a drive roller is installed on the outer wall of the drive motor.

[0007] A fixing rod is installed on the side wall of the conveyor frame, a fixing sleeve is installed on the outer wall of the fixing rod, a limit clamp is installed on the outer wall of the fixing rod, a positioning shaft is installed on the outer wall of the limit clamp, and a return spring is installed on the outer wall of the positioning shaft.

[0008] Preferably, the fixed platform is welded to the track frame via a connecting rod, and the turntable forms a rotating structure with the fixed platform via a rotary motor.

[0009] Preferably, the sliding sleeve is engaged with the track frame, and the roller is slidably connected to the track frame.

[0010] Preferably, the limiting sleeve is welded to the sliding sleeve, and the limiting sleeve is U-shaped.

[0011] Preferably, the limiting rod is symmetrically arranged with the central axis of the conveyor frame as the center, and the limiting rod is movably connected to the limiting sleeve.

[0012] Preferably, the fixing rod is threadedly connected to the fixing sleeve, and the fixing rod is movably connected to the limiting clamp.

[0013] Preferably, the limiting clamp plate forms a telescopic structure with the positioning shaft through a return spring, and the return spring is sleeved with the positioning shaft.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model uses a track frame, connecting rod, fixed platform, rotary motor, turntable, sliding sleeve and rollers. By starting the rotary motor, the turntable is driven to rotate. At this time, the turntable synchronously drives the sliding sleeve and rollers to rotate along the track frame, thereby meeting the transportation needs of multiple angles. Compared with a single transportation line, the multi-angle adjustable transportation efficiency of this utility model is higher and the space utilization rate is greater.

[0016] 2. This utility model uses an electric lifting rod, a power motor, a limit sleeve, a limit rod, a conveyor frame, a transmission motor, and a transmission roller shaft. By starting the power motor, the electric lifting rod is raised and lowered, thereby controlling the height of the conveyor frame. This meets the conveying and assembly needs of different vehicle models and chassis heights, and avoids interference between the car chassis and the roller bed due to unsuitable height, which would affect assembly efficiency and may even damage the car chassis or roller bed.

[0017] 3. This utility model, through the setting of a fixed rod, a fixed sleeve, a limiting clamp, a positioning shaft, and a return spring, controls the channel size above the transmission roller shaft by rotating the fixed sleeve and the thread of the fixed rod to adjust the size of the frame or parts to be conveyed, so that the limiting clamp can limit the conveyed material and prevent the transmission roller shaft from shifting when conveying materials of different sizes, thus affecting the subsequent assembly process.

The fixed platform 3 is welded to the track frame 1 through the connecting rod 2, and the turntable 5 forms a rotating structure with the fixed platform 3 through the rotary motor 4. The sliding sleeve 6 is engaged with the track frame 1, and the roller 7 is slidably connected to the track frame 1. Through the arrangement of the track frame 1, connecting rod 2, fixed platform 3, rotary motor 4, turntable 5, sliding sleeve 6, and roller 7, the rotary motor 4 is started to drive the turntable 5 to rotate. At this time, the turntable 5 synchronously drives the sliding sleeve 6 and roller 7 to rotate along the track frame 1, thereby meeting the multi-angle transportation needs. Compared with a single transportation line, the multi-angle adjustable transportation of this utility model has higher efficiency and greater space utilization.

[0026] Please see Figures 1-4A height-adjustable main roller bed includes an electric lifting rod 8 mounted on the top of a turntable 5, a power motor 9 mounted on the side wall of the electric lifting rod 8, a limit sleeve 10 mounted on the top of a sliding sleeve 6, a limit rod 11 mounted on the inner wall of the limit sleeve 10, a conveyor frame 12 mounted on the top of the limit rod 11, a drive motor 13 mounted on the side wall of the conveyor frame 12, and a drive roller shaft 14 mounted on the outer wall of the drive motor 13. The limit sleeve 10 is welded to the sliding sleeve 6 and is U-shaped. The limit rod 11 is positioned centered on the central axis of the conveyor frame 12. The system is configured such that the limiting rod 11 is movably connected to the limiting sleeve 10. Through the electric lifting rod 8, power motor 9, limiting sleeve 10, limiting rod 11, conveyor frame 12, transmission motor 13, and transmission roller shaft 14, the power motor 9 is started to drive the electric lifting rod 8 to lift and lower, thereby controlling the height of the conveyor frame 12. This meets the conveying and assembly needs of different vehicle models and chassis heights, avoiding interference between the vehicle chassis and the roller bed due to unsuitable height, which would affect assembly efficiency and may even damage the vehicle chassis or roller bed.

[0027] Please see Figures 1-4 A height-adjustable main roller bed is disclosed. A fixed rod 15 is mounted on the side wall of the conveyor frame 12. A fixed sleeve 16 is mounted on the outer wall of the fixed rod 15. A limiting clamp 17 is mounted on the outer wall of the fixed rod 15. A positioning shaft 18 is mounted on the outer wall of the limiting clamp 17. A return spring 19 is mounted on the outer wall of the positioning shaft 18.

Through the fixed rod 15, fixed sleeve 16, limiting clamp 17, positioning shaft 18, and return spring 19, the size of the channel above the drive roller shaft 14 is controlled by rotating the fixed sleeve 16 and the fixed rod 15 to adjust the dimensions of the required conveyed frame or parts. This allows the limiting clamp 17 to limit the conveyed material, preventing the drive roller shaft 14 from shifting when conveying materials of different sizes, thus avoiding interference with subsequent assembly processes.

[0028] Working principle: In use, first move the device to the required position, and then, according to the size of the frame or parts to be conveyed, adjust the channel size above the transmission roller shaft 14 by rotating the fixed sleeve 16 and the fixed rod 15 to limit the conveyed material with the limiting clamp 17, preventing the transmission roller shaft 14 from shifting when conveying materials of different sizes, which would affect subsequent assembly processes. Then, start the rotary motor 4 to drive the turntable 5 to rotate. At this time, the turntable 5 synchronously drives the sliding sleeve 6 and roller 7 to rotate along the track frame 1, thereby meeting the transportation needs of multiple angles. Compared with a single transportation line, this utility model... The multi-angle adjustment improves transportation efficiency and space utilization. Then, the electric lifting rod 8 is raised and lowered by starting the power motor 9, thereby controlling the height of the conveyor frame 12 to meet the transportation and assembly needs of different vehicle models and chassis heights. This avoids interference between the car chassis and the roller bed due to unsuitable height, which would affect assembly efficiency or even damage the car chassis or roller bed. Finally, the transmission motor 13 is started to drive the transmission roller shaft 14 to rotate and transport the equipment. This completes the use of the device.
