Disc tool carrying gear shifting device

Abstract

The invention discloses a carrying tooth stirring device for a disc cutter. The carrying tooth stirring device for the disc cutter comprises a machine frame, a cutter hanging mechanism and a tooth stirring mechanism. The tooth stirring mechanism comprises a tooth stirring rotating shaft, a tooth stirring pivot base, a first tooth stirring driving assembly, a tooth stirring driving wheel, a tooth stirring frame body, a bearing, an elastic washer and a second tooth stirring driving assembly, wherein the tooth stirring frame body is provided with an assembling channel. The tooth stirring pivot base is pivoted to the machine frame. The first tooth stirring driving assembly drives the tooth stirring frame body arranged on the tooth stirring pivot base to rotate. The tooth stirring rotating shaft is arranged in the assembling channel in a penetrating mode, and the lower end of the tooth stirring rotating shaft extends out in the radial direction of the tooth stirring rotating shaft to form an abutting portion provided with a tooth stirring head. The elastic washer and the bearing are assembled in the assembling channel in sequence, and the tooth stirring rotating shaft is sleeved with the elastic washer and the bearing in a matched mode. The tooth stirring driving wheel is located above the elastic washer and arranged on the tooth stirring rotating shaft. The tooth stirring driving wheel enables the elastic washer to be extruded between the tooth stirring driving wheel and the tooth stirring bearing in an elastically deformed mode. The elastic washer enables the tooth stirring rotating shaft to bear axial tensile force distributed from the lower side of the tooth stirring frame body to the upper side of the tooth stirring frame body. Thus, tooth stirring positioning accuracy of the disc cutter is improved.

Description

technical field [0001] The invention relates to a load-bearing gear shifting device, in particular to a disc cutter bearing gear shifting device capable of improving the gear positioning accuracy of the disc cutter. Background technique [0002] As we all know, in order to improve the wear resistance of disc cutters, in addition to reasonable design on the material of disc cutters and the manufacturing process of disc cutters, another best way is to add The saw teeth are welded with wear-resistant alloy welding pieces, through which the saw teeth of the disc cutter are more wear-resistant, so as to reduce the use cost of the disc cutter. Therefore, various welding machines emerge as the times require. . [0003] Among them, in all kinds of welding machines, there is a load-bearing gear shifting device, through which each saw tooth in the disc cutter is moved to the welding mechanism of the welding machine to ensure that the welding The mechanism can normally weld the alloy...

Problems solved by technology

[0005] But, because the shifting rod swings around the pivot shaft to realize the shifting of the disc cutter, it will jump when the driver drives the shifting rod to shift the teeth. Interfering with the disc cutter after shifting the gear affects the accuracy and reliability of the positioning of the shifting gear; especially, after the gear shifting lever has been shifted multiple times, it will wear and tear between the pivot shaft and produce a gap. At this time, the beating of the gear lever is more serious, which further affects the accuracy and reliability of the positioning of the gear, and correspondingly increases the cost of replacing the pivot shaft or the gear lever.

[0006] At the same time, the knife-hanging mechanism carrying the shifting gear device includes a knife-hanging body, a knife-hanging shaft for the disc cutter to socket, and a motor to drive the knife-hanging shaft to rotate; since the knife-hanging shaft is pivotally connected to the knife-hanging body, And it is driven by the motor installed on the hanging tool holder body, so in the process of rotating the hanging knife shaft, there will be wear between the hanging knife shaft and the hanging knife holder body. The wear between the tool holder bodies creates a gap between the tool holder shaft and the tool holder body, and the gap is finally transmitted to the disc cutter set on the tool holder shaft, thus affecting the reliability of the disc cutter gear shifting
