Description

Connection structure

Technical Field

The present invention relates to a connecting structure.

Background

In the prior art, the support of the exciter is usually fixed and positioned by inserting the indexing plunger into the fixing portion. However, when the index plunger pin is damaged and is not inserted into the hole, there is a risk of falling off. Further, since the insertion process is performed manually by an operator, when the insertion is not completed or dust or the like is present and the insertion cannot be performed, the pin of the index plunger may not penetrate into the hole portion and may be detached.

Prior art document 1 discloses a connecting mechanism in which a convex portion of a guide rail is mounted in a groove of a holder in parallel with the ground, and an applicator is fixed on an irradiation head. The rail is provided with a groove that engages with the plunger, and with a notch that connects to the groove in the travel direction of the rail.

In the attachment mechanism, since the rail is parallel to the ground, even if the rail does not advance before the piston is engaged with the plunger due to dust or the like, the applicator does not fall off, but in the case where the guide rail and the holder are positioned in the vertical direction, if the plunger cannot be engaged with the recess, there is a risk that the applicator falls off.

Detailed Description

Fig. 1A and 1B are schematic views of a connection structure 100 before and after installation according to an embodiment of the utility model, fig. 2A to 2C are schematic cross-sectional views of the connection structure 100 shown in fig. 1B on a line a-a ', and fig. 3A to 3C are schematic cross-sectional views of the connection structure shown in fig. 1B on a line B-B', respectively. A specific structure of the connection structure 100 will be described below with reference to fig. 1A to 3B.

Referring to fig. 1A to 3B, in the present embodiment, a connecting structure 100 is used to connect a clamp 120 holding a workpiece W to a vibrator of an inspection apparatus D. For example, the inspection apparatus D may apply vibration through a vibrator and thereby find cracks in the sheet material by vibrating the pressed sheet material through the workpiece W, but the present invention is not limited thereto.

Specifically, as shown in fig. 1A and 1B, in the present embodiment, the connection structure 100 includes a fixing portion 110 and a clamp 120, and the clamp 120 includes a holding portion 130 and a connecting portion 140. The fixing portion 110 is provided on the inspection apparatus D and has a fixing surface S110. The holding portion 130 of the jig 120 holds the workpiece W at one end of the jig 120, and at the other end of the jig 120, the connecting portion 140 of the jig 120 is connected to the fixing portion 110 and has a connecting surface S140. The fixing surface S110 and the connecting surface S140 face each other and are parallel to each other in the vertical direction DG.

Further, as shown in fig. 1A, in the present embodiment, the fixing portion 110 includes: groove 111, hole 112, and inclined portion 113. The grooves 111 are provided at both ends of the fixing part 110. Two holes 112 are provided, including a first hole 112a and a second hole 112b, both provided on the fixing surface S110, and recessed with respect to the fixing surface S110 of the fixing portion 110. Also, one of hole portions 112 (in the present embodiment, second hole portion 112b) is an elongated hole, and the longitudinal direction of the elongated hole is parallel to the extending direction of groove 111. Inclined portion 113 is inclined with respect to fixing surface S110 such that the thickness of the end portion side of fixing portion 110 becomes thinner from the end portion of one of hole portions 112 formed as a long hole toward the end portion of fixing portion 110.

On the other hand, as shown in fig. 1A and 1B, in the present embodiment, the connection portion 140 includes: plunger 141, hook 142, and flange 143. In the present embodiment, the plunger 141 is, for example, an indexing plunger 141, and two plungers 141 are provided, including a first plunger 141a and a second plunger 141b, where the first plunger 141a is used for positioning and the second plunger 141b is used for preventing falling off.

Also, as shown in fig. 2A to 3C, in the present embodiment, the first plunger 141a and the second plunger 141b have pins PN, respectively, and the pins PN of the first plunger 141a and the pins PN of the second plunger 141b protrude from the connecting face S140 and are capable of advancing and retreating in the axial direction of the plunger 141. Further, when the clip 120 is mounted to the fixing portion 110 of the connection structure 100, the hook portion 142 of the connection portion 140 is mounted along the extending direction of the groove 111 and engaged with the groove 111 of the fixing portion 110, that is, in the present embodiment, the extending direction of the groove 111 is the mounting direction of the clip 120. Also, as shown in fig. 2A and 3A, in the present embodiment, at the time of mounting the jig 120 to the fixing section 110 of the connecting structure 100, since the pin PN of the first plunger 141a and the pin PN of the second plunger 141B can advance and retreat in the axial direction of the plunger 141, the inclined section 113 of the fixing section 110 can press down the pin PN of the first plunger 141a and the pin PN of the second plunger 141B at a certain angle, and when the pin PN of the first plunger 141a and the pin PN of the second plunger 141B are moved to the place of the first hole portion 112A and the second hole portion 112B of the hole portion 112, as shown in fig. 2B and 3B, the pin PN of the first plunger 141a and the pin PN of the second plunger 141B can be projected again to engage with the first hole portion 112A and the second hole portion 112B of the hole portion 112 on the connection surface S140, respectively. As described above, in the present embodiment, as shown in fig. 2B and 3B, when the mounting is completed, the flange portion 143 can contact the lower end surface of the fixing portion 110, and the lower end surface is orthogonal to the concave groove 111 of the fixing portion 110.

As shown in fig. 2C and 3C, in the present embodiment, by providing two plungers 141 and holes 112 corresponding to each other, even when the insertion of the first plunger 141a for positioning into the first hole 112a is not completed or the first hole 112a cannot be inserted due to dust or the like and the retracted state is maintained, the second plunger 141b for preventing the falling-off can be engaged with the second hole 112b formed as the long hole, and the risk of the falling-off can be prevented.

In addition, in the embodiment, the second hole 112b is formed as a long hole, so that the detachment process is labor-saving, compared with the two holes 112 formed as circular holes. For example, with the connection structure 100 having the hole portions 112 both formed as circular holes, it is necessary to pull the two plungers 141 at the same time to detach them at the time of detachment, and it is necessary to apply a force twice as much as that when pulling down the single plunger 141. However, in the present embodiment, since the second hole portions 112b are formed as long holes, the first and second plungers 141a and 141b can be sequentially withdrawn from the corresponding hole portions 112 by pulling them one after another. For example, the detaching process can be easily performed by pulling the first plunger 141a for positioning and lifting the inspection device D, so that the pin PN of the first plunger 141a can be firstly released from the first hole part 112a, and thus, it is not necessary to continuously pull the first plunger 141a and then pull and lift the second plunger 141 b.

As described above, in the connecting structure of the present invention, by providing two corresponding plungers and hole portions and arranging one of the hole portions (i.e., the second hole portion) to be an elongated hole, even when the insertion of the first plunger for positioning into the first hole portion is not completed or the first plunger cannot be inserted into the first hole portion due to dust or the like and is held in the retracted state, the second plunger for preventing the falling-off can be engaged with the second hole portion formed as the elongated hole, and the risk of the falling-off can be prevented, and the connecting structure of the present invention can be provided with good reliability.

Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
