Description
Technical Field
The utility model relates to the technical field of working machines, in particular to a pin shaft hole alignment device, a pin shaft connection structure and a working machine.
Background
The pin shaft is used for connecting the components, and when the components are connected, the pin shaft holes of the two components are aligned, and then the pin shaft is inserted into the pin shaft holes of the components. However, the alignment of pin openings between larger volume or weight components has been a difficult task for the operator.
For example, in a rotary drilling machine, when a hoisting rack is mounted to a vehicle body frame, it is necessary to align a connecting pin shaft hole of the rack with a connecting pin shaft hole of the frame, and then mount the connecting pin into the connecting pin shaft hole of the rack and the connecting pin shaft hole of the frame. When the alignment of the connecting pin shaft hole of the rack and the connecting pin shaft hole of the rack is out of timing, the crane is usually adopted to hoist the rack for lifting and horizontal movement, and after the deviation is reduced, the spot assembly is usually carried out in a manner of beating the pin shaft, so that the alignment is forced.
However, since the mass of the gantry is generally large, it is very inconvenient to move. If the pin shaft hole is offset in the horizontal direction, the rack can be driven to move by beating the pin shaft. If the pin shaft hole deviates at the vertical height, the sling of the crane can be pulled when the pin shaft is hit, and the crane is easy to damage. In addition, the hammering of the pin shaft easily causes deformation of the pin shaft and the pin shaft hole, and the disassembly and the secondary installation are difficult.
Therefore, how to solve the problem of difficulty in aligning pin holes between components with larger volume or larger weight in the prior art is an important technical problem to be solved by those skilled in the art.

All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
In order to solve the problem that pin holes between large-size or heavy-weight components are difficult to align in the prior art, the embodiment provides a pin hole alignment device for assisting in aligning pin connecting holes of a first component and a second component.
In some embodiments, the first and second components may be a frame of the work machine and a skid of the hoisting device, respectively. The frame and the bench have larger weight and volume, so that the frame and the bench are required to be split for transferring in order to facilitate transportation and transferring, and then assembled after being transported to a target site.
Referring to fig. 1 and 2, the pin shaft hole alignment device provided in this embodiment includes an eccentric shaft 11, where the eccentric shaft 11 includes a first shaft section 111 and a second shaft section 112, the first axis of the first shaft section 111 and the second axis of the second shaft section 112 deviate, and when the first shaft section 111 rotates with its first axis as the axis, the second shaft section 112 can eccentrically rotate with the first axis as the axis. The first shaft section 111 is adapted to fit within the shaft bore 151 of the first member 15 and is rotatable about a first axis. The second shaft section 112 is configured to eccentrically rotate about the first axis and is capable of abutting against the second member.
In some embodiments, the first and second members 15, 111 fit within the shaft bore 151 of the first member 15 with the first member and the second member in place, and are capable of rotating within the shaft bore 151 of the first member 15. When the first shaft section 111 rotates in the shaft hole 151 of the first component 15, the second shaft section 112 can abut against the second component, and the eccentric shaft 11 cannot continue to rotate under the resistance of the second component.
In the state where the first member 15 and the second member are connected, that is, the pin shaft is correspondingly inserted into the pin shaft connecting hole of the first member 15 and the second member, the rotation angle of the eccentric shaft 11 needs to be corrected first, and the first shaft section 111 of the eccentric shaft 11 is rotated to eccentrically move the second shaft section 112 of the eccentric shaft 11, so that when the second shaft section 112 of the eccentric shaft 11 rotates to abut against the second member, the rotation of the eccentric shaft 11 is blocked. At this time, the eccentric shaft 11 is fixedly connected with the first component 15, so that the rotation angle calibration of the eccentric shaft 11 is completed. When the first component 15 and the second component are detached to be connected again, only the second component is required to be propped against the second shaft section 112 of the eccentric shaft 11 on the first component 15, which indicates that the pin shaft connecting hole of the second component and the first component 15 is aligned.
The positioning device has the advantages that the position calibration function of the second component can be achieved through the rotation of the eccentric shaft 11, when the second component is propped against the calibrated eccentric shaft 11, the alignment of the pin shaft connecting holes of the first component 15 and the second component is completed, the first component 15 or the second component is not required to be adjusted and aligned, and the problems of component damage and the like caused by the misalignment of the pin shaft connecting holes of the first component 15 and the second component are avoided.

In some embodiments, the diameter of the first shaft section 111 is smaller than the diameter of the second shaft section 112, and for ease of installation of the eccentric shaft 11, the diameter of the first through hole of the first member 15 is larger than the diameters of the first shaft section 111 and the second shaft section 112, so that the second shaft section 112 can pass through the first through hole of the first member 15. After the second shaft section 112 passes through the shaft hole 151 of the first component 15, the end cover 12 is covered on the shaft hole 151, and since the end cover 12 is provided with the first through hole, the diameter of the first shaft section 111 can be slightly smaller than that of the first through hole, so that the first shaft section 111 can rotate in the first through hole, and the first shaft section 111 is restrained by the end cover 12 and cannot generate larger shaking.
