BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 This is a schematic diagram of the overall structure of this application;

[0014] Figure 2 for Figure 1 Exploded diagram. DETAILED DESCRIPTION

[0015] The technical solution of the utility model is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0016] join Figure 1 and Figure 2 The figure is a schematic diagram of the structure of the rivet pressing device of the present application. The rivet pressing device of the present embodiment includes two parts: a supporting mechanism 1 and a pressing mechanism. The supporting mechanism 1 is used to feed the aluminum sleeve and rivet that have not been pressed. The pressing mechanism is used to press the aluminum sleeve 4 and the rivet 5 on the supporting mechanism 1.

[0017] like Figure 1 As shown, the bearing mechanism 1 includes a dividing plate 11 and a mold 12. The dividing plate 11 is set in the middle position and is driven by a driving device to rotate. A number of positioning holes 13 are evenly distributed on the dividing plate 11, and a mold 12 is placed in each positioning hole 13. The application of the dividing plate 11 provides multiple workstations, and loading, pressing, testing, etc. can be completed simultaneously on the same dividing plate. The mold 12 is placed in the positioning hole 13, and the mold 12 is used to carry the aluminum sleeve and rivet that have not been pressed.

[0018] Combination Figure 1 and Figure 2As shown, the pressing mechanism includes a bracket 21, a first cylinder 22, a clamping plate 23, a clamping column 24 and a bottom ejection support mechanism. The bracket 21 is arranged beside the bearing mechanism 1, corresponding to the indexing plate. The bracket 21 includes a base 211, a front group column 212, a rear group column 213 and a top plate 214. The bracket 21 is flexibly connected to the side of the bearing mechanism 1 through the base 211, which is convenient for changing positions and adapting to different workstation requirements. The first cylinder 22 is fixedly covered on the top plate 214. The clamping plate 23 is connected to the front group column 213 through a linear bearing 231, and the clamping plate 23 is connected to the end of the telescopic rod of the first cylinder 22. The clamping plate 23 moves up and down along the front group column 212 under the drive of the first cylinder 22. The clamping column 24 is connected to the clamping plate 23, and the clamping column 24 presses the rivet and aluminum sleeve in the mold 12 when the clamping plate 23 moves downward to connect them together.

[0019] Because the support 21 is located beside the indexing plate, when the pressing column 24 applies downward force to the indexing plate 11, the indexing plate 21 will tilt and shake, thereby affecting the operational stability of other positions of the indexing plate. Therefore, the present application further provides a bottom ejection support mechanism.

[0020] The bottom ejection support mechanism includes an ejection frame 25, an ejection bracket 26 and a stabilizing rod 27. Figure 2 As shown, the ejection frame 25 is fixed on the base 211. The ejection frame 25 is provided with a transverse through hole 251 and a vertical through hole 252, and the vertical through hole 252 intersects and communicates with the transverse through hole 251. The ejection bracket 26 is connected to a second cylinder 28, and the second cylinder 28 is fixed on the base 211. The ejection bracket 26 is driven by the second cylinder 28 to extend into or withdraw from the transverse through hole 251. The ejection bracket 26 includes a smooth flat plate 261, a support block 262 fixed on the smooth flat plate 261, and a ramp plate 263 fixed on the support block 262. The support block 262 is connected to the telescopic rod of the second cylinder 28. The ejection bracket 26 forms a structure with a slope on the surface, and gradually enters the transverse through hole as pushed by the second cylinder 28. The stabilizing bar 27 is penetrated in the vertical through hole 252, and the stabilizing bar 27 is lifted up as the ejection bracket 26 is extended, and is lowered as the ejection bracket 26 is withdrawn. The stabilizing rod 27 is correspondingly arranged below the indexing plate 11. A relief hole 271 is arranged at the top of the stabilizing rod 27. When the top of the stabilizing rod 271 is in contact with the bottom surface of the indexing plate 11, the bottom of the rivet and the aluminum sleeve are both located in the relief hole 271. A sealing plate 253 is arranged at the outer side of the transverse through hole 251. When the ejection bracket 26 completely enters the transverse through hole 251, the top of the stabilizing rod 27 is in contact with the bottom surface of the indexing plate, and the stabilizing rod 27 provides stable support for the indexing plate 11.

[0021] In order to ensure stable support, a limiting hole 272 is provided at the bottom of the stabilizing rod 27 . The limiting hole 272 is matched and clamped on the upper surface of the ejection bracket 26 to limit the ejection bracket and facilitate the ejection of the stabilizing rod 27 .

[0022] The present application has a simple structure, and the dividing plate realizes the possibility of multi-station detection. At the same time, the dividing plate serves as a pressing platform, which simplifies the structure, reduces the space occupied by the entire assembly line, and supports the dividing plate with a bottom ejection support mechanism to prevent it from shaking during the pressing process, thereby ensuring the stability of the dividing plate pressing process.

[0023] The above-described embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. Equivalent changes and modifications made to the present invention by those skilled in the art should all fall within the scope of the claims attached to the present invention.
