  • Patent number: 11446786
    Abstract: An object is to enable accurate machining by enabling shots to be accurately blasted on a workpiece even while workpiece is being deformed. A part manufacturing system includes: a peening device including a nozzle that projects a plurality of shots toward a workpiece, and a sensor that detects a distance to the workpiece; and a machining robot including a hand to which the peening device is attached, and a control unit that adjusts a position or an orientation of the peening device by controlling the hand based on the distance detected by the sensor.
    Type: Grant
    Filed: February 14, 2018
    Date of Patent: September 20, 2022
    Assignees: MITSUBISHI HEAVY INDUSTRIES, LTD., SINTOKOGIO, LTD.

  • Patent number: 9889488
    Abstract: A peening device is provided with: peening impact pins that impact on a surface to be worked; a device main body that uses vibration to move the peening impact pins back and forth with respect to the surface to be worked; servo motors (22x, 22y) that adjust the inclination of the device main body with respect to the surface to be worked; laser displacement gauges (20A, 20B, 20C, 20D) that detect the device angle; and a vibration sensor (18) that detects the vibration state of the device main body. Furthermore, a control device (40) for the peening device controls the servo motors (22x, 22y) such that the vibration state detected by the vibration sensor (18) is a predetermined vibration state. Thus, the peening device carries out excellent peening by conforming to the surface to be worked, the shape of which changes from moment to moment because of the peening.

  • Patent number: 9802234
    Abstract: A curvature retaining device (1) includes two support points (25a) that can abut against one surface of a plate-shaped workpiece W, one or more pressing points (40a) that can abut against a position of the other surface of the plate-shaped workpiece (W) between the support points (25a), and forward/backward drive means (support unit (23) and pressing unit (33)) for moving at least either the support points (25a) or the pressing points (40a) forward to and backward from the other. Preferably, the two support points (25a) abut against the one surface of the plate-shaped workpiece (W) at a first distance (Ls), the two pressing points (40a) abut against the other surface of the plate-shaped workpiece (W) at second distance (Lp) shorter than the first distance (Ls), and a middle point of the first distance (Ls) and a middle point of the second distance (Lp) match with each other.

  • Patent number: 9789526
    Abstract: Provided are a highly-versatile plate-like-workpiece twisting and retaining apparatus, plate-like-workpiece twisting and retaining method, and plate-like-workpiece twisting and shaping method that can give a freely-chosen twisted shape or curved shape to a plate-like workpiece with a simple, highly-versatile configuration without having to prepare a die member and that can also be applied to an integral skin. A twisting and retaining apparatus includes at least two support points that are contactable with a first surface in a twisting range of a plate-like workpiece; a plurality of pressing points that are similarly contactable with a second surface in the twisting range and that flank a line connecting the at least two support points in plan view of the plate-like workpiece; and an advance-retract driving apparatus (support unit, pressing unit) that causes at least the support points or the pressing points to advance and retract in a thickness direction of the plate-like workpiece.
