Description

Technical Field

[0001] The utility model belongs to the field of mechanical equipment, and particularly relates to a novel double-sided overhead rotary assembly line. Background Art

[0002] The double-sided overhead rotary assembly line is composed of a closed circular rotary line, a number of wire harness workbench trolleys arranged at equal intervals and running on the overhead platform, a transmission system and a PLC electrical control system. The running trolley on the assembly line is driven by a conveyor chain after the speed is adjusted by a frequency converter, and runs on the platform at the linear speed set by the process.

[0003] At present, the operation of the workbench trolley is driven by the chain in the drag chain track. The workbench trolley only has guide wheels but no guide tracks. The workbench trolley will be affected by the uneven ground during operation, and the workbench trolley will derail, roll over and other problems. The main structure of the trolley adopts a single-layer square tube, which has weak deformation resistance. When the tooling plate installed on the workbench above the trolley is heavy, the main body of the trolley will undergo irreversible deformation.

[0004] Therefore, in view of the shortcomings of the above-mentioned scheme in actual production and implementation, it has been revised and improved. At the same time, in the spirit and concept of seeking excellence, with the assistance of professional knowledge and experience, and after many ingenuity and experiments, the present utility model was created. A new type of double-sided overhead rotary assembly line is provided to solve the problems of large footprint, poor stability and low safety. Utility Model Content

[0007] The circular turntable includes a straight rail, a curved rail and a bracket, wherein the straight rail and the curved rail form a closed track connected end to end, and the bracket is used to support the circular turntable, and an overhead platform is laid on the circular turntable;

[0008] The harness workbench trolley comprises a symmetrically arranged trolley, wherein a guide wheel is arranged inside the trolley, a universal wheel is arranged at the bottom of the trolley, and a guide wheel baffle is arranged at the top of the guide wheel.

[0009] When the entire assembly line starts running, the running trolley on the assembly line is driven by the conveyor chain after the speed is regulated by the frequency converter, and moves on the platform according to the linear speed set by the process. When the running trolley reaches the end of the straight track on one side, the running trolley carries the workbench along the curved track to the beginning of the straight track on the other side.

The height of the overhead platform is adjusted by the feet. The workbench trolley walks on the overhead platform without being affected by the uneven ground, thereby avoiding the risk of derailment and rollover of the workbench trolley. At the same time, the workload of debugging the assembly line is reduced, and it is also convenient to move the assembly line.

[0011] As a preferred embodiment, a trolley stand is provided in the middle of the wiring harness workbench trolley, and symmetrical workbenches are obliquely arranged on both sides of the trolley stand. The trolley is a double-layer square tube box structure, and the main structure of the trolley is changed to a double-layer square tube box structure, which has enhanced anti-deformation ability, prevents irreversible deformation caused by the installation of relatively heavy tooling plates, and extends the service life of the assembly line.

[0012] As a preferred embodiment, the wiring harness workbench trolley includes a trolley, a guide wheel is arranged on the inner side of the trolley, a universal wheel is arranged on the lower part of the trolley, a guide wheel baffle is arranged on the upper part of the guide wheel, a guide wheel baffle design is added, and guide grooves are added at the head and tail of the assembly line, so that the workbench trolley runs more smoothly and reliably, and the safety of the assembly line is improved.

[0013] As a preferred embodiment, the diameter of the overhead platform is larger than the diameter of the trolley, so that the wire harness workbench trolley can run smoothly on the overhead platform.

[0014] As a preferred embodiment, the guide wheel baffle is arranged in cooperation with the guide wheel, an outer pedal is arranged on the outer side of the trolley, and an inner pedal is arranged on the inner side of the trolley.

[0015] As a preferred implementation manner, a guide groove is arranged on the outer side of the guide wheel, and the guide groove is arranged in cooperation with the guide wheel.

[0016] After adopting the above technical scheme, the beneficial effects of the utility model are: adding guide wheel baffles and guide grooves to improve the stability and safety of the trolley operation, designing an overhead platform, laying galvanized steel plates, achieving smooth operation of the trolley, facilitating the mobility of the assembly line, and the box-type structure of the trolley body, which solves a series of problems and hidden dangers caused by the deformation of the trolley main body structure and extends the service life of the assembly line.
