Description

Technical Field

[0001] The utility model relates to a spiral component orthopedic device, belonging to the technical field of orthopedic equipment. Background Art

[0002] The conveying device of the crawler grain harvester includes an outer cylindrical shell and an inner spiral component. The spiral component includes a central main shaft and spiral blades arranged on the main shaft. Since the spiral component is a welded part and has a slender structure, it is difficult to ensure coaxiality during the welding process, resulting in serious deformation after welding, causing the spiral component straightness and spiral component outer circle runout to exceed tolerance. After the spiral welded component with excessive runout is assembled into the cylindrical shell, the gap between the shell and the spiral component is uneven due to the non-concentricity of the two components, and there may even be interference friction between the two components, which affects the crop conveying efficiency and even causes crop damage.

[0003] Therefore, the welded spiral parts need to be straightened before assembly. At present, the welded spiral parts usually adopt the manual straightening process: first, visually check the bending direction and approximate bending amount, then manually apply pressure in the opposite direction, visually check again, and then straighten; then check on the platform whether it meets the requirements, if not, continue with the previous process until it meets the requirements.

[0004] At present, due to the complete reliance on manual labor, the labor intensity of employees is high and the efficiency is low. In addition, the straightening process measurement is inaccurate, resulting in a long production cycle and certain safety hazards. Therefore, in order to improve the output, quality and safety of slender welded spiral parts, a spiral part correction device is needed. Utility Model Content

[0020] Furthermore, the orthopedic mechanism also includes a fixed seat, and the pressure head driving component includes a hydraulic cylinder, which is installed on the fixed seat, and the piston rod end of the hydraulic cylinder is fixedly connected to the orthopedic pressure head.

[0021] The beneficial effect of adopting the above further technical solution is: the orthopedic pressure head is driven to rise and fall by the hydraulic cylinder, thereby achieving the orthopedic effect on the spiral component.

[0022] Furthermore, it also includes a sensor and a PLC control system, wherein the sensor is used to detect the stroke of the orthopedic pressure head, and the sensor and the hydraulic cylinder are respectively connected to the PLC control system signal.

[0023] The beneficial effect of adopting the above-mentioned further technical scheme is: according to the highest point of the main shaft of the spiral component, the correction amount of the spiral component is calculated and set through the PLC control system, and the set value is transmitted to the hydraulic cylinder. The hydraulic cylinder presses down a preset distance according to the set value preset by the PLC control system, and the stroke of the correction pressure head is detected by the sensor. By returning the data to the PLC control system, it is determined whether the correction pressure head is pressed into place, thereby realizing accurate correction and straightening operation of the spiral component.

[0024] Furthermore, a display screen and an operation interface are provided on the fixing base, and the display screen and the operation interface are respectively connected to the PLC control system signal.

[0025] The beneficial effect of adopting the above further technical solution is that by arranging a display screen and an operation interface on the fixed base, it is convenient for workers to operate.

[0026] Furthermore, it also includes at least two safety gratings, which are arranged at two ends of the workbench, the supporting mechanism and the corrective mechanism are arranged between the two safety gratings, and the safety gratings are connected to the PLC control system signal.

[0027] The beneficial effect of adopting the above further technical solution is that the main function of the safety grating is to protect personnel and equipment from accidental injuries.
