In the case of this embodiment, the urging member 84 is a coil spring, and the urging member 84 constantly urges the rod member 82 in the direction in which it is inserted into the hole 81, that is, in the upward direction.

The restriction mechanism 80 having such a configuration is engaged with the lower plate member 33b by inserting the upper end of the rod member 82 into the hole 81, and restricts the movement of the reaction force receiving member 321. Moreover, the movement restriction | limiting of the reaction force receiving member 321 is cancelled | released by pulling down the knob 83 and releasing the upper end of the rod member 82 from the hole 81, and releasing engagement. By moving the reaction force receiving member 321 and engaging the rod member 82 with another hole 81, the distance between the rod portion 31b of the press-fit cylinder 31 and the reaction force receiving member 321 can be changed (adjustable). ). For this reason, the freedom degree of the magnitude | size of the workpiece | work which can be pinched | interposed between the rod part 31b and the reaction force receiving member 321 improves, and it can respond to a wider range with respect to the workpiece | work from which a magnitude | size differs.

In the present embodiment, the plurality of holes 81 and the rod member 82 are employed as the restriction mechanism 80 as described above. However, the configuration of such engaged portions and engaging portions that are engaged with each other has various structures. Can be adopted. In the present embodiment, the rod member 82 (engagement portion) is urged by the urging member 84 toward the hole 81 (engaged portion). However, the present invention is not limited to this. The engaged portion may be urged by the urging member 84 toward the portion. That is, any one or both of the engaged portion and the engaging portion may be configured to be urged by the urging member 84 in the direction in which both are engaged.

<Release unit>
Next, the release unit 50 will be described with reference to FIG. FIG. 7 is a perspective view of the release unit 50. The release unit 50 holds the knob 83 of the restriction mechanism 80, pulls down the rod member 82, and releases the engagement between the rod member 82 and the hole 81.

<Press-fit jig>
The press-fitting jig 60 is used when there is no suitable surface (press-fitting receiving surface) on which the contact surface 321a of the reaction force receiving member 321 is in contact with the workpiece in the press-fitting work onto the workpiece by the press-fitting cylinder 31. For example, it is used when a press-fitting operation is performed on a work that does not have a surface orthogonal to the press-fitting direction line on the press-fitting direction line at the press-fitting location (hole WH) of the work. More specifically, for example, when a part is press-fitted into a hole formed obliquely (in a direction inclined from the normal direction of the one side surface) with respect to one side surface of the rectangular workpiece in plan view, the one side surface The other side opposite to the side (parallel to the one side) is not orthogonal to the press-fitting direction line and cannot be used as a press-fitting receiving surface. In such a case, the press-fitting jig 60 is used. 8 and 9 are perspective views of the press-fitting jig 60. FIG.

The press-fitting jig 60 includes a main body portion 61 attached to the workpiece W and an abutting portion 62 supported by an end portion of the main body portion 61. The main body 61 includes a plurality of positioning pins 61 a that determine the mounting position of the press-fitting jig 60 with respect to the workpiece W. The positioning pin 61a protrudes from the lower surface of the main body 61 and is inserted into a hole WH formed in the workpiece W, whereby the press-fitting jig 60 can be fixedly attached to the workpiece W, and The position of the press-fitting jig 60 is determined. The hole WH may be a hole originally provided in the workpiece W, or may be formed as a dedicated hole for inserting the positioning pin 61a. In this embodiment, the positioning pin 61a and the hole WH are used to determine the mounting position of the press-fitting jig 60 on the workpiece W. However, the present invention is not limited to this, and various positioning structures can be used.

In the case of this embodiment, the main body 61 has a rectangular plate shape, and a plurality of engaging portions 61b each having an opening are formed. The engaging portion 61b is for inserting claw members 75 and 76 (described later) of the mounting unit 70 to engage the front end portion of the claw member, and its inner wall has a stepped shape as indicated by a broken line. Yes.

The contact portion 62 includes a first contact surface 62a with which the contact surface 321a of the reaction force receiving member 321 contacts, and a second contact surface 62b. The first contact surface 62a and the second contact surface 62b have mutually different surface angles. As will be described later, the first contact surface 62a is formed perpendicular to the press-fitting direction of the first press-fitting hole Wa provided in the workpiece W. The second contact surface 62b is formed orthogonal to the press-fitting direction of the second press-fitting hole Wb having a different press-fitting direction from the first press-fitting hole Wa. The contact portion 62 may be formed integrally with the main body portion 61 or may be attached so as to be separable. When it is configured to be separably attached, a plurality of types of contact portions 62 having different contact surface orientations depending on the press-fitting direction are selectively attached to the main body portion 61. Compatible with multiple types of press-fitting directions.

FIG. 10 is a plan view and a front view of the press-fitting jig 60 attached to the workpiece W. The first press-fitting hole Wa is formed on one side surface of the workpiece W, and is a first target portion into which a part is press-fitted. Line L1 indicates the center line of the first press-fitting hole Wa, that is, the press-fitting direction. In the workpiece W, a plurality of first press-fit holes Wa whose lines L1 are parallel to each other are formed in a line. In the work W, there may be a case where the other side surface is located on the line L1 and does not have a surface orthogonal to the line L1. Therefore, in this case, the first contact surface 62a of the press-fitting jig 60 is used as a surface orthogonal to the line L1. Due to the positional relationship with respect to the positioning pin 61a, the first contact surface 62a is designed to be positioned on the line L1 and orthogonal to the line L1 when the press-fitting jig 60 is mounted on the workpiece W.

Further, the second press-fitting hole Wb is formed on one side surface of the workpiece W and is a second target portion into which a part is press-fitted. Line L2 indicates the center line of the second press-fitting hole Wb, that is, the press-fitting direction. The line L2 is not parallel to the line L1 (in the direction of about 45 degrees with respect to the line L1 in plan view), and the second press-fitting hole Wb is different from the first press-fitting hole Wa. In the workpiece W, a plurality of second press-fit holes Wb whose lines L2 are parallel to each other are formed in a row at a predetermined interval between the first press-fit holes Wa (or in the vicinity of the first press-fit holes Wa). . For example, in the workpiece W, the other side surface may be uneven, and there may be no surface that is located on the line L2 and orthogonal to the line L2. Therefore, in this case, the second contact surface 62b of the press-fitting jig 60 is used as a surface orthogonal to the line L2. The second contact surface 62b is designed so as to be positioned on the line L2 and orthogonal to the line L2 when the press-fitting jig 60 is mounted on the workpiece W due to the positional relationship with the positioning pin 61a.

In the case of this embodiment, since the plurality of first press-fit holes Wa and the plurality of second press-fit holes Wb are alternately formed in a line, the first contact surface 62a corresponds to each first press-fit hole Wa. The second contact surface 62b is provided corresponding to each second press-fitting hole Wb, and the first contact surface 62a and the second contact surface 62b as a whole are formed in a meandering shape. Yes.

The press-fitting jig 60 having such a configuration is mounted on the upper surface side of the work W as shown in FIG. 10 with respect to the work W placed on the table 6a at the press-fitting work position. Then, the table 6a is rotated and moved up and down by the drive unit 6b shown in FIG. 2, and the press-fitting direction of the press-fitting cylinder 31 is parallel to the line L1 direction or the line L2 direction depending on the target press-fitting holes Wa and Wb.
