Positioning device for feeding shaft barrel parts to machine tool through mechanical arm

Abstract

The invention belongs to the technical field of machining, and particularly relates to a positioning device for feeding shaft barrel parts to a machine tool through a mechanical arm. The device is composed of a bottom plate, a stand column, a supporting plate, a positioning block, a damping plate and an infrared induction device. The supporting plate is erected on the bottom plate through the stand columns, the damping plate is arranged on the end face of the lower end of the supporting plate, and the positioning block is arranged on the supporting plate and used for positioning a workpiece to be machined. The center lines of the damping plate and the positioning block coincide. An infrared sensing device is further arranged beside the damping plate and used for sensing whether the to-be-machined workpiece is positioned or not. And if the positioning is completed, a manipulator starting instruction is sent to start the manipulator to grab the positioning workpiece and send the positioning workpiece to a high-precision processing machine tool.

[0002] The high-precision processing machine tools used in mass production lines have extremely high requirements on the clamping position. When processing long-sized workpieces, especially for shaft-tube parts and stepped shaft-tube parts; usually through the chuck that comes with the machine tool , hydraulic calipers to clamp and position the workpiece to be processed; the long-sized workpiece to be processed on the production line is generally transported to the area to be processed through the conveyor line or the pallet on the conveyor belt; and then grasped by the manipulator to the clamping and positioning position of the high-precision processing machine tool; To improve processing efficiency, the manipulator in the parts production line is used to automatically load and unload the workpiece for grabbing; the position of the manipulator is fixed, the grabbing point is fixed, and it is controlled by pre-set program instructions; however, during the processing and placement of large quantities of workpieces, cannot Ensure that the placement position of each workpiece on the pallet is exactly the same; when the workpiece is directly grabbed from the pallet and sent to a high-precision processing machine, the positioning and clamping of the workpiece to be processed on the machine tool cannot be accurately guaranteed, resulting in the scrapping of the workpiece

[0003] In order to solve this problem, in the field of intelligent manufacturing, the conventional processing method is to carry out matching design in the process of manipulator program control; on the one hand, it is necessary to carry out adaptive design on the structure of the manipulator; Perform matching adjustment control; the program control system is complex, at least it is necessary to obtain known parameters such as the position of the feeding tray, the position of the workpiece to be processed on the feeding tray, and the shape of the workpiece to be processed. The coordination of these parameters requires complex measurement or sensing Components; after obtaining the above parameters, cooperate with the corresponding control system integration algorithm to complete the program control of the entire feeding process

It can be seen that in order to achieve this goal, the construction cost of the production line has been greatly increased, and the actual realization is extremely difficult.
