Bent axle locating mechanism used for automatically feeding and discharging by robot

Abstract

The invention relates to a bent axle locating mechanism used for automatically feeding and discharging by a robot. The bent axle locating mechanism comprises a locating seat, an axial locating mechanism and a circumferential locating mechanism, wherein the locating seat comprises a first V-shaped seat and a second V-shaped seat; the axial locating mechanism comprises an axial locating block and an axial power mechanism which drives the axial locating block; the circumferential locating mechanism comprises a circumferential locating component, an elastic buffered piece and a vertical linear driving mechanism, wherein the circumferential locating component comprises a first locating rod and a second locating rod which are arranged oppositely, the first locating rod and the second locating rod are connected to a connecting seat, the first locating rod is fixedly connected with the connecting seat, and the second locating rod is connected with the connecting seat through a height adjustment mechanism; the elastic buffered piece is arranged between the connecting seat and the vertical linear driving mechanism, and a vertical guide mechanism is arranged between the connecting seat and the vertical linear driving mechanism. By means of the locating mechanism, accurate axial location, radial location and multi-angle circumferential location can be conducted on a bent axle.

Description

technical field [0001] The invention relates to a workpiece positioning mechanism in the automatic loading and unloading process of a robot, in particular to a crankshaft positioning mechanism for automatic loading and unloading of a robot. Background technique [0002] When machining crankshafts in industries such as household appliances, it is necessary to ensure accurate positioning of the crankshaft in the axial and radial directions. In the prior art, the crankshaft to be processed is generally placed in the machine tool by manual loading, and the workpiece positioning is realized through the radial positioning stoppers arranged inside the machine tool. This loading method seriously restricts the implementation of automatic machining of the crankshaft. [0003] see figure 1 , the figure shows a crankshaft structure in household appliances, the crankshaft 19 includes a first rotating shaft 19-1 and a second rotating shaft 19-2 arranged eccentrically, and the first rotat...

Problems solved by technology

And for the different processing techniques of different crankshafts 19, the circumferential positioning state of the crankshaft 19 before being sent into the machine tool has different requirements, that is, in different processing occasions, the distance between the reference plane 19-4 on the transition block 19-3 and the horizontal plane The angle between them is changing, so the existing positioning method cannot meet this requirement
