Description
Technical Field
The utility model relates to a door lock, in particular to a coaxial multi-part connecting and assembling structure.
Background
When the two flanges are connected through the bolts, the two flanges are usually positioned through the middle positioning hole and the positioning shaft, and then one flange is rotated to align the bolt holes and then is connected and fixed. At this moment, if increase the third connecting piece again between two flanges, three part still fixes a position according to preceding middle locating hole, location axle, and the bolt hole site alignment needs to be carried out to the second part dress after on first part, and the third part of repacking, still need carry out the bolt hole site alignment to three part this moment, and rotatory arbitrary part this moment, two other parts all can follow the rotation, cause the hindrance to aligning the bolt hole to influence the equipment rhythm, reduce assembly efficiency. For example, in the connection of a transmission connecting flange, a transmission shaft connecting flange and a torsional vibration damper which are commonly used at present, a radial positioning shaft is arranged on the end face of the transmission connecting flange, a first radial positioning hole is formed in the transmission shaft connecting flange, a second radial positioning hole is formed in the torsional vibration damper, four bolt holes corresponding to the transmission connecting flange and the transmission shaft connecting flange are formed in the end face of the transmission connecting flange, the transmission shaft connecting flange and the torsional vibration damper are respectively sleeved on the radial positioning shaft of the transmission connecting flange through the first radial positioning hole and the second radial positioning hole to be in clearance fit with the radial positioning shaft and are connected with the transmission connecting flange through bolts, and the torsional vibration damper is located between the transmission connecting flange and the transmission shaft connecting flange after connection. However, in the connection process, after the torsional vibration damper is aligned with the bolt hole of the transmission connecting flange, the transmission shaft connecting flange is mounted, so that the transmission shaft connecting flange needs to be rotated to align the bolt holes, and the middle torsional vibration damper rotates along with the transmission shaft connecting flange, so that the torsional vibration damper and the bolt hole of the transmission connecting flange need to be misaligned. In the assembling process, the processes can be repeated, and the assembling efficiency is seriously reduced.
