Combined press-mounting table for peeling roller of corn harvesting machine

Abstract

The invention discloses a combined press-mounting table for a peeling roller of a corn harvesting machine. The combined press-mounting table comprises a peeling roller rubber sleeve press-mounting table, a duplex-bearing block press-mounting table and a hydraulic station, wherein the peeling roller rubber sleeve press-mounting table comprises first positioning seats, aligning devices and pressure heads, the first positioning seats are horizontally arranged on a first frame in sequence, and the pressure heads are fixed at one ends of long-stroke oil cylinders; the duplex-bearing block press-mounting table comprises second positioning seats and a duplex pressure head, the second positioning seats are vertically arranged on a second frame in sequence, and the duplex pressure head is fixed at one end of an oil cylinder; the long-stroke oil cylinders and the oil cylinder are connected with the hydraulic station respectively; the peeling roller rubber sleeve press-mounting table can guarantee the quality of press mounting of peeling roller rubber sleeves, the duplex-bearing block press-mounting table can guarantee the quality of press mounting of duplex-bearing blocks; manual operation is replaced by mechanical operation, and the peeling roller rubber sleeve press-mounting table and the duplex-bearing block press-mounting table are combined together to form a workflow, so as to facilitate line production, shorten the turn-over time of workpieces and improve the assembly efficiency of the peeling roller of the corn harvesting machine.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery and equipment, in particular to a corn harvester peeling roller combined pressing platform. Background technique [0002] The peeling roller is an important part of the corn peeling machine, such as figure 1 As shown, the multi-section (generally 3 to 5 sections) skinning roller rubber sleeve 1 is press-fitted on the skinning roller shaft 2, and the skinning roller shaft 2 is press-fitted on the double bearing housing 3 to form a skinning roller. The peeling work of corn is realized by the opposite rotation of two adjacent peeling roller rubber sleeves 1 . At present, the assembly of the peeling roller generally requires manual assembly. [0003] Because the peeling roller is a slender shaft, the interference between the rubber sleeve of the peeling roller and the shaft of the peeling roller is relatively large, and the rubber sleeve needs to be compressed at the end to be loaded ...

AI Technical Summary

Problems solved by technology

[0003] Since the peeling roller is a slender shaft, the interference between the rubber sleeve of the peeling roller and the shaft of the peeling roller is relatively large, and the positioning pin needs to be compressed at the end of the rubber sleeve, so the vertical assembly is too high to operate

For horizontal assembly, due to the small positioning surface and too long cantilever, it is difficult to keep the shaft level, and the coaxiality of the indenter and the shaft cannot be guaranteed during press-fitting, posing safety hazards

In addition, the rubber sleeves of the peeling rollers are relatively short, and each peeling roller can only be completed by multiple pressings according to the number of rubber sleeves, resulting in low assembly efficiency

[0004] The double bearing seat is assembled with a tool, the force is uneven, and the bearing is easy to be damaged

However, the two ends of the peeling roller shaft are equipped with a bearing seat, and the workpiece needs to be turned over when assembling with a beating tool, which is labor-intensive and low in efficiency.

In addition, after the peeling roller is pressed, the peeling roller assembly is transferred to the next station for bearing seat assembly, which is time-consuming and laborious, and requires a large area

[0005] It can be seen that the existing manual peeling roller assembly process is inefficient, and the assembly quality is difficult to guarantee
