Centering adjustment method and system for clamping jaw type chuck

Abstract

The invention discloses a centering adjustment method for a clamping jaw type chuck. The centering adjustment method comprises the following steps: S101, calibrating the axis of a sensing column and a rotary shaft of the clamping jaw type chuck; S102, pre-clamping a workpiece; S103, performing connective mounting of an adjusting assembly and the clamping jaw type chuck; S104, acquiring pressure on the sensing column produced by all following connecting pieces based on a pressure sensor of the sensing column and building corresponding relation of the radian and the pressure; S105, judging the radian position required to be adjusted based on the corresponding relation of the radian and the pressure; S106, performing adjustment by using the adjusting unit corresponding to a small bevel gear being closest to the radian position which is required to adjust the distance based on the radian position required to be adjusted until a pressure value of the radian position required to be adjusted is consistent with a preset value; and S107, repeating the steps from S104 to S106 until the corresponding relation of the radian and the pressure is consistent with the preset relation, and then ending the centering adjustment of the clamping jaw type chuck. According to the method and the system, centering adjustment of the chuck can be automatically carried out, and the method and the system have the advantages of being high in automation degree and high in centering adjustment accuracy.

Description

technical field [0001] The invention relates to the field of machine tools, in particular to a centering adjustment method and system for a jaw type chuck. Background technique [0002] figure 1 A schematic structural view of a prior art three-jaw chuck is shown. In the machining process of shaft parts, the claw chuck is one of the commonly used workpiece fixing fixtures, and the three-jaw chuck (also known as the three-jaw chuck) is the most common type of claw chuck. [0003] Generally, the operation principle of the jaw chuck is that the connecting part is driven to move by the driving part, and several jaws 101 are evenly matched on the connecting part. Driven to move towards or away from the axis of the connecting piece synchronously. [0004] Concretely, for the three-jaw chuck, the driver is a small bevel gear 103 (generally there are multiple bevel gears along the circumferential direction of the large bevel gear 102), the connector is a large bevel gear 102, and ...

Problems solved by technology

[0007] Generally, the existing three-jaw chuck is used as follows: after the workpiece is clamped, the jaws are driven to clamp the workpiece by driving the small bevel gear. After clamping, the different small bevel gears are respectively operated twice, and the operation is completed Finally, after turning the three-jaw chuck, use the instrument to measure the surface bounce of the workpiece when it rotates, and then adjust the three-jaw chuck until the bounce is within the preset range. Since the above operations need to be completed by manpower, it takes a long time and the accuracy is high. Can not control
