Abstract

The invention relates to the technical field of machinery assembly, in particular to a hole-aligning device. The hole-aligning device is used for enabling pin shaft holes of a first member and a second member to be aligned; the hole-aligning device comprises a driving mechanism and an auxiliary assembly piece; the driving mechanism is connected with one end of the auxiliary assembly piece to drivethe auxiliary assembly piece to move back and forth in the first direction; the first member and the second member are located at the other end of the auxiliary assembly piece, and the auxiliary assembly piece and the pin shaft holes to be assembled are roughly located on a same axis; the head end, facing the pin shaft holes, of the auxiliary assembly piece is in a gradual contraction shape, so that the head end of the auxiliary assembly piece smoothly enters the pin shaft holes under the action of driving of the driving mechanism; and then the auxiliary assembly piece continues moving on, until the outer wall of a column body of the auxiliary assembly piece can abut against the inner walls of the pin shaft holes of the first member and the second member at the same time, so that the alignment of the first member and the second member is conveniently and fast finished, and pin shafts can be smoothly inserted into the pin shaft holes of the first member and the second member.

Description

technical field [0001] The invention relates to the technical field of mechanical assembly, in particular to a hole aligning device. Background technique [0002] At present, when assembling large-scale mechanical equipment such as the working device of an excavator, the structural parts need to be connected by pin shafts; before assembling the pin shafts, it is necessary to align the pin holes of the structural parts to be connected, and make the alignment accuracy reach wire level, so that the pin shaft can be smoothly inserted into the pin hole of the structural parts to be connected; but at present, the alignment of the pin holes between the structural parts is done manually, and the accuracy of the hole alignment mainly depends on the experience of the operator. The installation of the shaft often requires repeated disassembly of the pin shaft and multiple adjustments of the relative positions between the structural parts, which is time-consuming, laborious and ineffici...
