Figure 2 is a schematic cross-sectional view of Figure 1. In the present embodiment, the insert grasping jig 1a includes a fixing member 10, a plurality of elastic members 20, a pushing member 30, and a connecting member. In this embodiment, the connecting member is a lever 40.

In the present embodiment, the fixing member 10 has a cross shape. However, it is not taken as an example. In other embodiments, the fixing member 10 may be polygonal or circular.

Each elastic member 20 includes a connecting portion 21, a grasping portion 22, a first pushed portion 23 and a second pushed portion 24. The connecting section 21 of the spring member 20 is connected to the opposite side of the fixing member 10. The grab section 22 is opposite the connecting section 21. The first pushed section 23 is located between the connecting section 21 and the gripping section 22. The first pushed section 23 has a pushed inclined surface 231 facing the side of the joystick 40. The pushed slope 231 has opposing first sides 2311 and second sides 2312. The first side 2311 of the beveled surface 231 is closer to the connecting section 21 than the second side 2312. The second pushed section 24 has a receiving surface 241 on the inside, and the second pushed section 24 connects the first side 2311 of the first pushed section 23.

In the present embodiment, the elastic members 20 are exemplified by four, but are not limited thereto. In other embodiments, the number of resilient members 20 can be adjusted as needed. However, the amount of adjustment needs to satisfy the need to maintain the part that can be securely gripped by the gripping section 22 of the spring member 20. In addition, in the embodiment, each elastic member 20 includes a plurality of elastic rods 25. Each of the elastic rods 25 can move relative to each other, so that even if the parts have irregular shapes, the elastic rods 25 can be adapted to the irregular shape of the parts so that the gripping sections 22 of the elastic rods 25 can grip the parts more closely.

The pushing member 30 has an outer edge 31. The outer edge 31 of the pushing member 30 abuts against the pushed inclined surface 231 of the first pushed portion 23 of the elastic member 20 or the pushed inclined surface 241 of the second pushed portion 24. In this embodiment, the pushing member 30 is exemplified by a rectangular plate shape, but is not limited thereto. In other embodiments, the pushing member 30 may have other shapes.

The lever 40 can drive the pushing member 30 to push the outer edge 31 of the pushing member 30 against the pushed inclined surface 231 of the first pushed portion 23 of the elastic member 20, and is relatively far away from or close to the fixing member 10 along a sliding direction A1. The grasping section 22 of the elastic member 20 is retracted or expanded. The lever 40 can also push the pushing member 30 to push the outer edge 31 of the pushing member 30 against the pushed surface 241 of the second pushed portion 24 of the elastic member 20, so that the grasping portion 22 of the elastic member 20 is fixed. The degree of opening and closing.

The inclined relationship of the above-mentioned pushed inclined surface 231 is related to the sliding direction A1, that is, the normal direction A2 of the pushed inclined surface 231 and the sliding direction A1 are at an acute angle. In detail, the axis A3 of the joystick 40 is parallel to the sliding direction A1 and passes through the center point of the fixture 10. When the insert grips the jig 1a unclamped part, the distance from the first side 2311 of the push ramp 231 to the axis A3 is greater than the distance of the second side 2312 to the axis A3. That is, the inclined surface 231 of the first pushed portion 23 of the elastic member 20 is an inclined surface having a fixed slope, and the inclined surface is farther from the axis A3 on the side close to the connecting portion 21, on the inclined surface The other side is closer to the axis A3. Further, when the insert grips the jig 1a without holding the part, the fascia 241 is parallel to the axis A3. However, it is not limited thereto. In other embodiments, the elastic member 20 can determine whether to set the second pushed portion 24 and the pushed surface 241 according to requirements.

The following describes the manner in which the plug-in gripping jig 1a is used to grasp the part. Please refer to Figures 3a to 3d. 3a to 3d are schematic views showing the operation of the plug-in gripping member of the plug of Fig. 1. First, as shown in Fig. 3a, the insert gripping jig 1a is aligned with the part 80 to be gripped. Next, as shown in FIG. 3b, an operator (not shown) can move the joystick 40 in the direction indicated by the arrow a to drive the pusher 30 closer to the first side 2311 from the first pushed section 23. The position of the second side 2312 is to enlarge the degree of opening and closing of the gripping section 22 of each elastic member 20, that is, to enlarge the clamping range of the insert gripping jig 1a. Next, as shown in FIG. 3c, the part to be grasped 80 is placed in the clamping range and surrounded by the grasping section 22 of the elastic member 20, and the operator operates the operating lever 40 to drive the pushing member 30 by the inclined surface 231. The second side 2312 moves toward the first side 2311. During this operation, the gripping section 22 of the resilient member 20 will gradually retract until the gripping section 22 of the resilient member 20 is retracted to be grippable and attached to the part 80. Finally, as shown in FIG. 3d, the operator operates the joystick 40 again to move the pushing member 30 to the second pushed portion 24 and pushes the pushing member 30 against the pushed surface 241 of the second pushed portion 24. . Due to the position of the second pushed section 24 at this time, the pushed up surface 241 is still parallel to the axis A3, so that even if the insert gripping jig 1a is shaken during the grasping process, the pusher 30 is relatively opposed to the second When the pusher segment 24 is displaced up and down, the grasping section 22 of the elastic member 20 is not affected by the pushing member 30 pushing against the second pushed section 24, so that the grasped part 80 is not Will loose or fall during the crawling process.

As described above, the insert gripping jig 1a can adjust the gripping range of the gripping member 22 of the elastic member 20 to the size of the part by adjusting the position of the pushing member 30 at the inclined surface 231. In this way, only a single jig can be used to firmly grasp various sizes of parts, and it is no longer necessary to replace different jigs according to different size parts in the assembly process, thereby reducing assembly cost and shortening assembly time.
