Locking device

Abstract

The invention provides a locking device for position locking of a floating rail which is conveyed in the vertical direction. The locking device includes a support, a drive portion connected to the support so as to output the driving force, and a connection portion configured to detachably and fixedly connected to the floating rail, wherein locking grooves are formed in the connection portion; thelocking device also includes a drive bearing portion pivoted to the support via a pivoting shaft; the drive bearing portion is drivingly connected between the drive portion and the connection portion;and corresponding locking portions having the same number as the locking grooves are formed on the drive bearing portion. According to the locking device, the floating rail can be connected through the connection portion; the drive bearing portion is arranged on the support, the drive bearing portion can pivot with the respect to the support under the drive of the drive portion, locking of the connection portion can be achieved through clamping fit between the locking portions formed on the drive bearing portion and the locking grooves formed in the connection portion, and the floating rail can be locked by the locking device.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a locking device for locking a floating rail. Background technique [0002] At present, in automobile manufacturing, it is often necessary to use the conveying system to transport workpieces. In order to meet the needs of the process, it is often necessary to transport the workpieces from the ground to the air for hanging. At this time, it is necessary to use a broken rail lifting device to achieve ground Production air delivery purposes. The smooth docking of the floating track and the fixed track in the broken-rail lifting device plays a key role in the stable operation of the equipment, and a track locking mechanism is usually installed at the track interface. [0003] Most of the locking mechanisms in the prior art use the cooperation form of the bolt and the socket to realize the connection between the floating track and the fixed track, that is, when the f...

AI Technical Summary

Problems solved by technology

[0003] Most of the locking mechanisms in the prior art use the cooperation form of the bolt and the socket to realize the connection between the floating track and the fixed track, that is, when the floating track is lifted to the docking position with the fixed track in the vertical direction, the bolt on the fixed track will Inserted into the socket, since the insertion direction of the pin is parallel to the length direction of the floating track, the floating track will move axially along the pin axis during use, resulting in the problem of uneven docking

In addition, due to the use of pins and sockets in the long-term use process, there will be problems that the steel structure cannot be inserted and stuck and cannot be pulled out due to the slight deformation of the steel structure.
