It will be appreciated that attachment of the accessory head 61 to the accessory head test platform 11 may be accomplished by a plurality of gripping assemblies 300 gripping a plurality of staples 71 in a one-to-one correspondence.

It will be appreciated that the spacing between the plurality of staples 71 will also vary with the size and type of the attachment head 61 in order for the attachment head 61 to remain stationary under the coaction of the plurality of staples 71. By arranging the plurality of adjusting plates 220 and installing the plurality of gripping assemblies 300 on the plurality of adjusting plates 220 in a one-to-one correspondence, when each adjusting plate 220 moves relative to the connecting plate 210, the adjusting plates 220 can drive the gripping assemblies 300 to move relative to the connecting plate 210, and the spacing between the plurality of gripping assemblies 300 can be changed to correspond to the plurality of blind rivets 71 installed on the accessory heads 61 with different sizes one by one.

The rotation axis of the adjusting plate 220 relative to the connecting plate 210 is the central axis of the outer circumferential surface of the adjusting plate 220. In the present application, the inner wall surface of the mounting groove 211 is a cylindrical surface that can be bonded to the outer peripheral surface of the adjusting plate 220, so that the inner wall surface surrounding the mounting groove 211 can define the adjusting plate 220 within the mounting groove 211.

The offset of the mounting hole 221 from the central axis is understood to mean that the geometric center of the mounting hole 221 is offset from the central axis of the outer circumferential surface. In this application, the mounting hole 221 is a circular hole, and the central axis of the mounting hole 221 is deviated from the central axis of the outer circumferential surface of the adjustment plate 220, and the grasping assembly 300 is mounted centering on the central axis of the mounting hole 221, so that the grasping assembly 300 can be rotated around the central axis of the outer circumferential surface of the adjustment plate 220 to change positions during the rotation of the adjustment plate 220 relative to the connection plate 210.

In particular, in the present application, the connection assembly 200 further includes a plurality of first locking members 230, and the adjusting plate 220 can rotate relative to the connection plate 210 to have a plurality of predetermined rotational positions, and in any predetermined rotational position, the plurality of first locking members 230 can cooperate together to lock the adjusting plate 220 with the connection plate 210.

Specifically in this application, the attachment head 61 is provided with a threaded hole (not shown), and the blind rivet 71 is screwed with the threaded hole, so that the attachment head 61 can be detachably connected, and the threaded hole can be used when the attachment head 61 is connected with a corresponding structure on the machine tool at a later stage.

In the above-mentioned test system, a plurality of blind rivets 71 are connected to the accessory head, so that a plurality of gripping assemblies 300 in the accessory head test platform grip a plurality of blind rivets 71 in a one-to-one correspondence manner, thereby realizing quick connection of the accessory head 61 and the accessory head test platform 11, and the blind rivets 71 are detachably connected to the accessory head 61, so that after the end of the test of the accessory head 61, the blind rivets 71 can be detached from the accessory head 61 so as not to affect the installation of the accessory head 61 on a machine tool in the later stage.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The above examples only represent a few embodiments of the present application, which are described in more detail and are not to be construed as limiting the scope of the claims. It should be noted that it would be apparent to those skilled in the art that various modifications and improvements could be made without departing from the spirit of the present application, which would be within the scope of the present application. Accordingly, the scope of protection of the present application is to be determined by the claims appended hereto.
