Abstract
A manufacturing method of an ultrasonic generating device includes applying a compressive force to an attachment unit toward a first axial direction while a first end of a bolt-shaped member is a free end and the second end thereof is fixed, and thereby generating a first elastic force in the attachment unit. The manufacturing method includes attaching a fastening member to a bar portion of the bolt-shaped member in a balanced condition in which a second elastic force of the bolt-shaped member and the first elastic force are in balance, and thereby maintaining the balanced condition.
Claims6
A manufacturing method of an ultrasonic generating device, the method comprising:
- attaching an attachment unit to a bar portion from a second axial direction side in a bolt-shaped member, the attachment unit including a piezoelectric element configured to convert a current to an ultrasonic vibration, a head portion forming a first end of the bolt-shaped member on a first axial direction side, the first axial direction being a direction parallel to a longitudinal axis, the bar portion smaller in an outside diameter than the head portion forming a second end of the bolt-shaped member on the second axial direction side, the second axial direction being opposite to the first axial direction;
- fixing, as a fixed end, the second end of the bolt-shaped member to which the attachment unit is attached, by using a bolt fixing portion of a jig, while the bolt-shaped member is expandable by a movement of the first end which is a free end toward the first axial direction;
- applying a compressive force to the attachment unit toward the first axial direction by a force applying unit while the second end of the bolt-shaped member is fixed, and thereby generating a first elastic force in the attachment unit;
- and
- attaching a fastening member to the bar portion of the bolt-shaped member in a balanced condition in which a second elastic force of the bolt-shaped member and the first elastic force of the attachment unit are in balance, and fastening the attachment unit between the fastening member and the head portion of the bolt-shaped member to maintain the balanced condition.
An assembling system of an ultrasonic generating device, the system comprising:
- a bolt-shaped member, the bolt-shaped member including a head portion forming a first end of the bolt-shaped member on a first axial direction side, the first axial direction being a direction parallel to a longitudinal axis, and a bar portion which is smaller in an outside diameter than the head portion and which forms a second end of the bolt-shaped member on the second axial direction side, the second axial direction being opposite to the first axial direction;
- an attachment unit which includes a piezoelectric element configured to convert a current to an ultrasonic vibration, and which is attached to the bar portion of the bolt-shaped member from the second axial direction side;
- a jig which includes a bolt-shaped member fixing portion, the bolt-shaped member fixing portion fixing, as a fixed end, the second end of the bolt-shaped member to which the attachment unit is attached while the bolt-shaped member is expandable by an movement of the first end which is a free end toward the first axial direction;
- a force applying unit which is configured to apply a compressive force to the attachment unit toward the first axial direction while the second end of the bolt-shaped member is fixed, and thereby configured to generate a first elastic force in the attachment unit;
- and
- a fastening member which is attached to the bar portion of the bolt-shaped member in a balanced condition in which a second elastic force of the bolt-shaped member and the first elastic force of the attachment unit are in balance, and which is configured to fasten the attachment unit between the fastening member and the head portion of the bolt-shaped member to maintain the balanced condition.
