Problems solved by technology

Due to the tolerance in the size of each positioning hole of a batch of workpieces, in order to avoid interference between the positioning pins and the positioning holes of the traditional positioning device with two pins on one side for positioning workpieces with two holes on one side, it is necessary to ensure that each positioning pin is in line with the corresponding positioning hole during design. There is a minimum gap between the positioning holes. Due to the existence of the gap, when the workpiece is positioned on the positioning device, displacement errors and rotation angle errors in the X and Y directions will occur, which will cause a large positioning error in the positioning system and affect the processing. Accuracy, reduce processing efficiency and quality

Abstract

The invention discloses a one-face two-pin precise positioning system. The one-face two-pin precise positioning system is characterized by comprising a worktable, a round pin positioning device, a diamond pin positioning device and a control system; the control system comprises a first power device and a second power device, the first power drive drives a first plunger to move in a plunger hole of a round pin, the round pin is driven to move upwards by upwards extruding hydraulic plastics, the positioning portion of the round pin is inserted into a corresponding positioning hole of a workpiece, the positioning portion of the round pin generates corresponding plastic deformation and expands, and the gap between the round pin and the corresponding positioning hole in the workpiece is reduced. The second power device drives a second plunger to move in a plunger hole of a diamond pin, the diamond pin is driven to move upwards by upwards extruding the hydraulic plastics, the positioning portion of the diamond pin is inserted into a corresponding positioning hole of the workpiece, the positioning portion of the diamond pin generates corresponding plastic deformation and expands, and the gap between the diamond pin and the corresponding positioning hole in the workpiece is reduced.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a precise positioning system with two pins on one side for precise positioning of workpieces and a control method thereof. Background technique [0002] In the process of mechanical manufacturing, the use of workpieces with one side and two holes for positioning can easily realize the unification of benchmarks in the process, ensure the mutual position accuracy of the workpiece processing surfaces, and have large supporting surfaces, good supporting rigidity, simple and reliable structure, and convenient loading and unloading of workpieces, etc. Advantages, so it is widely used in various special machine tools and process equipment of automatic lines. Due to the tolerance in the size of each positioning hole of a batch of workpieces, the traditional positioning device with two pins on one side for positioning workpieces with two holes on one side must ensure that each positio...
