Automatic transposition device for cross workpieces and control method

Abstract

The invention relates to an automatic transposition device for cross workpieces. The automatic transposition device comprises a first support and a reversing mechanism, and further comprises a main leveling mechanism, a proximity switch and a controller, wherein the main leveling mechanism is capable of being in frictional contact with the outer wall surface of a first shaft of a cross workpiece placed on the first support, and can be used for driving frictionally the cross workpiece to rotate around the axis of the first shaft of the cross workpiece; the proximity switch can be used for identifying whether a second shaft of the cross workpiece rotates to a horizontal state; and the controller communicates with the reversing mechanism, the main leveling mechanism and the proximity switch,and controls the reversing mechanism and the main leveling mechanism to act according to a preset program. According to the automatic transposition device for the cross workpieces, automatic levelingof the cross workpiece placed on the first support is carried out in a friction transmission mode, the applicability of the device is wider, and no leveling dead angles exist. The invention further relates to a control method of the automatic transposition device for the cross workpieces.

Description

technical field [0001] The invention relates to the technical field of cross workpiece grinding, in particular to an automatic indexing device and a control method for a cross workpiece. Background technique [0002] Existing cross workpieces, such as cross shafts, need to be ground at their two axial ends. In the existing grinding production line, the loading process of placing the cross workpiece on the grinding machine is more critical. an operation step. At present, most of the feeding devices for cross workpieces are hooked by movable hooks or gripped by manipulators, wherein, whether it is the two hooking parts of the hook or the two gripping parts of the manipulator, they are all set horizontally , which requires that the two shaft ends of the cross workpiece to be clamped or hooked need to be in a horizontal state to facilitate accurate grasping by hooks or manipulators. [0003] In the actual production process, when the two shaft ends in one axial direction of th...

Problems solved by technology

[0004] However, the indexing device of the feed mechanism of this centerless grinding machine also has certain deficiencies. Specifically, the indexing device adjusts it by moving the straightening block driven by the cylinder above the reversing table. However, when the manipulator takes the cross workpiece out of the grinding machine and then places it on the reversing table, the freely swingable shaft end of the cross workpiece may be in a vertical state or close to a vertical state, so that the straightening block in the above-mentioned patent It is difficult to adjust the cross workpiece to the horizontal state, and there is a leveling dead angle, which greatly affects the feeding efficiency of the cross workpiece, and even causes equipment failure, resulting in the failure of the normal operation of the grinding production line of the cross workpiece
