Description

Technical Field

[0001] The utility model relates to the field of a cylinder quick coupling device, in particular to a cylinder quick locking coupling transmission device. Background Art

[0002] The coupling is a mechanical part used to connect two shafts (driving shaft and driven shaft) in different mechanisms to rotate together to transmit torque. In automated production, a rotary motor is often used to drive the driven shaft to rotate. By connecting a push rod, push arm, brush, nylon base block, etc. to the driven shaft, the product can be automatically sorted, returned to its original position, and the surface of the rotating body can be cleaned or arranged. Different components are installed according to the requirements of the site of use.

[0003] like Figure 1 The figure shows an existing coupling transmission device 100', which includes a rotary cylinder 1', a key bar 2', a smooth rod 3' and a steel sleeve 4', the output shaft 11' of the rotary cylinder 1' is sleeved in one end of the smooth rod 2', and the key bar 2' passes through the through hole 31' of the smooth rod 3' and is fixed in the concave key groove 12' of the output shaft 11', the smooth rod 3' and the output shaft 11' are fixed by the key bar 2', and then the steel sleeve 4' is sleeved on the smooth rod 3' and is located outside the key bar 2', and finally a bolt is passed through the bolt hole 41' of the steel sleeve 4' and is abutted against the key bar 2', so as to fix the key bar 2' on the smooth rod 3' and the output shaft 11' of the rotary cylinder 1'. At present, the steel sleeve 4' of the coupling transmission device 100' is only fixed with a key bar 2' by one bolt, and the output shaft 11' and the light rod 3' of the rotary cylinder 1' are not tightened as a whole, resulting in that all transmission forces are only transmitted through the key bar 2', and the overall contact area is small. After the operation frequency is too high, the key bar will wear and fail, and the light rod and the output shaft will be disengaged and slipped, resulting in poor transmission stability, and it is difficult to install and remove the key bar during later maintenance. Moreover, the steel sleeve requires the light rod and the output shaft to be inserted and connected first, and then the key bar is installed, and then the bolt holes on the steel sleeve are aligned again, and the key bar is fixed by bolts, which is difficult to operate in a limited space. Summary of the invention

[0004] The technical problem to be solved by the utility model is that the utility model is a cylinder quick locking coupling transmission device with a simple structure and convenient and quick installation, which enables the rotating cylinder to be simply and quickly connected to the light rod in a limited space, and the connection is stable and reliable.

[0005] The utility model is implemented as follows: a rotary cylinder quick locking coupling transmission device, comprising a rotary cylinder, comprising an output shaft, wherein the output shaft is provided with a concave keyway;

[0008] A locking steel sleeve is a hollow structure, and a steel sleeve keyway is axially provided on its inner side wall. The locking steel sleeve is sleeved on the outside of the light rod, and the steel sleeve keyway is slidably provided on the upper end of the key bar. A steel sleeve deformation opening is axially provided on the side wall of the locking steel sleeve, and the steel sleeve deformation opening is locked by a locking mechanism.

[0009] Furthermore, the locking mechanism includes a locking platform opened on one side wall of the steel sleeve deformation opening, a plurality of bolt holes and a plurality of bolts opened on the locking platform, the bolt holes penetrate the upper and lower side walls of the steel sleeve deformation opening, and the bolts are passed from the bolt holes of the locking platform to the other side wall of the steel sleeve deformation opening.

[0010] The advantages of the utility model are: the output shaft of the rotating cylinder, the polished rod and the locking steel sleeve are fixedly connected at the same time by the key bar, so that the fixed connection surface of the key bar is increased, and the transmission stability is higher.
