Pull rod positioning mechanism that can rotate in multiple directions

Abstract

The invention discloses a pull rod positioning mechanism capable of rotating in multiple directions. The pull rod positioning mechanism comprises a left pull rod, a right pull rod, and two connecting shafts connecting the left and right pull rods, wherein the front ends of the left and right pull rods are connected with one connecting shaft, and the tail ends of the left and right pull rods are connected with the other connecting shaft. The pull rod positioning mechanism also comprises joint bearings and self-lubricating bearing sleeves, wherein the joint bearings are at least arranged at one end of each connecting shaft; the self-lubricating bearing sleeves are arranged outside the joint bearings in a sleeving manner. According to the pull rod positioning mechanism, the connecting shafts can perform inclination movement (namely aligning movement) within a certain angle range in spherical mounting grooves of bearing shells, and rotating spaces at multiple angles are formed when bearing bodies are not concentric with bearing shell holes under the action of external force, so that stress is resolved and buffered, the aim of flexibly rotating the pull rod positioning mechanism is fulfilled, the breaking efficiency of a breaking hammer is improved, and the service life of the bearings, the connecting shafts and the bearing sleeves is prolonged.

Description

technical field [0001] The invention relates to a pull rod positioning mechanism for a high-frequency breaker, in particular to a pull rod positioning mechanism capable of multi-directional rotation. Background technique [0002] The rotation direction of the high-frequency breaker is mainly realized by the pull rod positioning mechanism. The pull rod positioning mechanism includes a left pull rod and a right pull rod. A pair of connecting shafts are arranged between the left and right pull rods. The left and right pull rods are connected together. [0003] When the high-frequency breaker is working, the vibration box (vibrator) not only shifts in the horizontal direction during crushing, but also shifts in the vertical direction or in other directions, which will affect the accuracy of the tie rod positioning mechanism. Since the bearing can only be offset in the horizontal direction, but cannot be offset in the vertical direction or other directions, it will not only redu...

Problems solved by technology

[0003] When the high-frequency breaker is working, the vibration box (vibrator) not only shifts in the horizontal direction during crushing, but also shifts in the vertical direction or other directions, which will affect the accuracy of the rod positioning mechanism

Since the bearing can only be offset in the horizontal direction, but cannot be offset in the vertical direction or other directions, it will not only reduce the vibration energy in the crushing direction, but also reduce the crushing efficiency, and cannot obtain higher crushing efficiency when crushing hard objects. efficiency, and will cause damage to the bearing and other surrounding components

[0004] If things go on like this, due to the change of crushing force during crushing, the bearing is easily damaged, and the bearing, connecting shaft and bearing sleeve need to be replaced regularly, which greatly reduces its service life and affects the crushing efficiency of the crushing hammer and the positioning and crushing accuracy of the pull rod.
