In the present embodiment, the middle plate 212, the top plate 213 and the limiting plate 214 allow a plurality of bolts to pass through, and the middle plate 212 and the bottom plate 211 allow another bolt to pass through, so that two adjacent plates can be closely stacked without separation. The bottom plate 211 has a front side surface and a rear side surface on opposite sides in a front-rear direction D2 perpendicular to the up-down direction D1, an accommodating space 2111 extending from the front side surface to the rear side surface, two abutting portions 2112 on both sides of the accommodating space 2111 in the left-right direction D3, and four spaces 2113. The four spaces 2113 are bilaterally symmetrical to each other and spaced at the left and right sides of the accommodating space 2111, and are spaced front and back with the corresponding abutting portions 2112 therebetween. Each of the abutting portions 2112 has both side surfaces 2114 facing away from each other in the front-rear direction D2.

The middle plate 212 is formed with a plurality of limit through-holes 2121 corresponding to the mounting holes 921 (see fig. 3) of the workpiece 92, respectively, each of the limit through-holes 2121 extending in the up-down direction D1 from the top surface to the bottom surface.

The top plate 213 is formed with a plurality of buffering spaces 2131 corresponding to the limiting through holes 2121, and each of the buffering spaces 2131 extends from the top surface to the bottom surface in the vertical direction D1, so that the buffering spaces 2131 communicate with the limiting through holes 2121.

Referring to fig. 7, the position-limiting plate 214 has a concave bottom surface 2141 covering the buffering space 2131 of the top plate 213, two lower limiting surfaces 2142 having a lower horizontal height than the concave bottom surface 2141, an upper limiting surface 2143 opposite to the concave bottom surface 2141 and the lower limiting surface 2142, a plurality of lower through holes 2144 extending from the concave bottom surface 2141 to the upper limiting surface 2143 in the vertical direction D1 and communicating with the buffering space 2131, a plurality of sliding holes 2145 formed at opposite ends and extending from the lower limiting surface 2142 to the upper limiting surface 2143 in the vertical direction D1, and a plurality of lower blind holes 2146 formed at opposite ends and extending from the upper limiting surface 2143 to the lower limiting surface 2142. In this embodiment, the centers of the lower through holes 2144 correspond to the centers of the limiting through holes 2121, respectively. The number of the sliding holes 2145 is, for example, 4, and two sets of the two sliding holes 2145 are formed at the left and right ends of the limiting plate 214, and the two sliding holes 2145 of each set are spaced from each other in the front-rear direction D2, but not limited thereto. The number of the lower blind holes 2146 is, for example, 4, and two sets of the lower blind holes 2146 are formed at the left and right ends of the limiting plate 214, and the two lower blind holes 2146 of each set are spaced apart from each other between the two sliding holes 2145.

Referring to fig. 7, the carrier plate 22 is substantially rectangular and located above the base 21, and has a carrying surface 221 for placing the workpiece 92, a contact surface 222 opposite to the carrying surface 221, a plurality of upper through holes 223 extending from the carrying surface 221 to the contact surface 222 in the vertical direction D1 and corresponding to the lower through holes 2144, a plurality of fixing holes 224 corresponding to the sliding holes 2145 and extending from the contact surface 222 to the carrying surface 221 in the vertical direction D1, a plurality of upper blind holes 225 corresponding to the lower blind holes 2146 and extending from the contact surface 222 to the carrying surface 221, two first protrusions 226 protruding upward from the carrying surface 221 at opposite ends, two second protrusions 227 disposed at opposite sides of the carrying surface 221 in the left-right direction D3 at intervals, and protruding upward from the carrying surface 221, and a third protrusion 228 protruding upward from one side of the carrying surface 221. In the present embodiment, the two first protrusions 226 are respectively inserted into the two second positioning holes 111 (see fig. 2) of the pressing plate 11 to restrict the pressing plate 11 from moving in the front-back direction D2 and the left-right direction D3. The two second protrusions 227 are respectively inserted into the two first positioning holes 922 of the workpiece 92 to restrict the workpiece 92 from moving in the front-rear direction D2 and the left-right direction D3. The third protrusion 228 is used to penetrate the notch 923 of the workpiece 92 to serve as a fool-proof structure to ensure that the direction of the workpiece 92 is correct when it is installed.

Referring to fig. 7 and 8, the second spring 23 is disposed between the supporting plate 22 and the base 21, so that the supporting plate 22 can extend and contract along the up-down direction D1 relative to the base 21. In the present embodiment, the second springs 23 are, for example, compression springs, 4 in number, opposite ends of each second spring 23 respectively penetrate through the lower blind hole 2146 and the upper blind hole 225 corresponding to each other, and abut against the hole wall of the lower blind hole 2146 and the hole wall of the upper blind hole 225, so as to support the bearing plate 22, so that a gap is formed between the bearing plate 22 and the limiting plate 214, and the bearing plate 22 can move downward relative to the limiting plate 214. When the four second springs 23 are compressed by the carrier 22, the four second springs 23 store elastic restoring force, and when the four second springs 23 are not pressed by the carrier 22, the four second springs 23 release the elastic restoring force to apply upward force to the carrier 22, so that the carrier 22 is reset.

Referring to fig. 7 and 9, the guiding sub-module 24 is disposed between the base 21 and the supporting board 22, and the guiding sub-module 24 is used to limit the supporting board 22 to move along the up-down direction D1 relative to the base 21. Further, each guiding sub-module 24 has a limiting block 241, and two limiting sub-modules 242, which respectively and correspondingly extend through the two sliding holes 2145 of the limiting plate 214, and one end of each of the two limiting sub-modules is fixed to the limiting block 241, and the other end of each of the two limiting sub-modules is fixed to the supporting plate 22. In the present embodiment, the stopper 241 is generally elongated and extends in the front-rear direction D2. Each of the limiting sub-modules 242 has a sleeve 2421 slidably extending through the sliding hole 2145, an upper bolt 2422 passing through the fixing hole 224 and having an end locked to the sleeve 2421, and a lower bolt 2423 passing through the limiting block 241 and having an end locked to the sleeve 2421. More specifically, the supporting plate 22 further has a shoulder portion protruding inward from the wall of the fixing hole 224, and the upper bolt 2422 passes through the fixing hole 224 from the supporting surface 221 and extends downward, so that the upper end abuts against the upper edge of the shoulder portion and the lower end is engaged with the top end of the sleeve 2421. In addition, each limiting block 241 is also formed with two fixing holes corresponding to the two sleeves 2421, and another shoulder protruding inwards from the hole wall of the fixing hole, and the lower bolt 2423 penetrates upwards from the bottom surface of the limiting block 241 through the fixing hole so that the lower end abuts against the lower side edge of the shoulder, and the upper end is clamped at the bottom end of the sleeve 2421, so that the bearing plate 22 and the guide sub-module 24 are connected with each other. Therefore, when the carrier 22 is pressed downward by an external force, the guiding sub-module 24 is driven to move downward relative to the position-limiting plate 214 as shown in fig. 10. When the carrier 22 is not pressed by an external force and is biased to return by the second spring 23, the guiding sub-module 24 is driven to move upward relative to the position-limiting plate 214, and the lower limiting surface 2142 of the position-limiting plate 214 stops the limiting block 241 to limit the carrier 22 to move upward only to the position shown in fig. 9.

Referring to fig. 7, 11 and 12, two locking blocks 25 are movably mounted on opposite sides of the telescopic carrier module 2, and each locking block 25 can move between a locking position (shown in fig. 11) pressing against the corresponding extension arm 12 and a releasing position (shown in fig. 12) separated from the corresponding extension arm 12 relative to the telescopic carrier module 2. In the present embodiment, the two locking pieces 25 are placed in the accommodating space 2111 and the space 2113, and spaced from each other in the front-rear direction D2. For each of the locking blocks 25, each of the locking blocks 25 is movable in the front-rear direction D2 with respect to the bottom plate 211, and has a main body 251 having a substantially rectangular shape and disposed in the accommodating space 2111, and two stoppers 252 extending oppositely from opposite ends of the main body 251 and disposed in the space 2113, respectively. The main body 251 has a pressing end 2511 exposed outside the accommodating space 2111. Each of the blocking bodies 252 is formed with a blind hole 2521 at a side surface adjacent to the side surface 2114 of the abutting portion 2112. In the locking position, the locking block 25 partially protrudes out of the accommodating space 2111, so that the pressing end 2511 presses against the hook 122 of the corresponding extension arm 12, and the blocking body 252 abuts against the bottom plate 211; in the release position, the locking block 25 is partially retracted into the accommodating space 2111 to separate the pressing end 2511 from the hook 122 of the corresponding extension arm 12.

Each of the first springs 26 is configured to apply an elastic force to the corresponding click block 25 to be positioned at the click position. In the present embodiment, the four first springs 26 are respectively disposed in the four spaces 2113 in pairs, and each pair of the two first springs 26 is spaced apart from each other in the left-right direction D3, and each first spring 26 extends in the front-back direction D2, and opposite ends of the first spring respectively abut against the side wall 2114 and the blind hole 2521, so as to apply an elastic force to the corresponding locking block 25 to be positioned in the locking position.

Referring to fig. 7 and 13, the top bracing module 3 includes a plurality of top bracing columns 31, a plurality of elastic members 32 and a plurality of lantern rings 33. But not limited to this, the top bracing module 3 may also perform rivet positioning by the top bracing column 31 cooperating with the elastic element 32. In the present embodiment, the number of the top brace 31 is 8 for example, the number of the elastic member 32 is 8 for example, and the number of the collar 33 is 8 for example, but the number of the top brace 31, the elastic member 32 and the collar 33 may be determined according to the actual design requirement of the workpiece 92.

Referring to fig. 13 and 14, each of the supporting pillars 31 penetrates through the telescopic carrier module 2 and can move along the up-down direction D1. Each top brace 31 has a column 311, in the present embodiment, each column 311 extends through the upper through hole 223, the lower through hole 2144, the buffering space 2131 and the limiting through hole 2121 which are connected up and down, and is limited by the hole walls forming the upper through hole 223, the lower through hole 2144 and the limiting through hole 2121 and can only move in the up-down direction D1. In addition, the top brace 31 forms a flange 312 extending outward in the radial direction on the outer surface exposed in the buffering space 2131, and the flange 312 is limited by the concave bottom surface 2141 to limit the upward movement distance of the column 311 in the up-down direction D1. Each post 311 has a top end 3111 projecting from the bearing surface 221 for seating a corresponding rivet 91.

Referring to fig. 13 and 14, the elastic element 32 is installed in the telescopic carrier module 2, and is sleeved on the corresponding column 311, and is used for applying an upward elastic force to the supporting pillar 31. When the workpiece 92 is pressed down, it is pressed and riveted to the rivet 91 and compresses the elastic members 32 through the supporting columns 31, respectively. In the present embodiment, each elastic member 32 is, for example, a disc spring, but not limited thereto. A plurality of elastic members 32 are stacked up and down and placed in the buffering space 2131 and sleeved on the corresponding column 311 of the top brace 31. For each elastic element 32, there are an upper surface 321 and a lower surface 322 on two opposite sides. In each set of elastic members, the upper surface 321 of the uppermost elastic member 32 is supported against the lower side edge of the flange 312 of the top support column 31.

Referring to fig. 13 and 14, the collar 33 is sleeved on the column 311 and is close to the bottom end of the column 311, so that the set of elastic members 32 is located between the collar 33 and the flange 312, and the lower surface 322 of the elastic member 32 at the lowest position in each set of elastic members 32 is supported against the top surface of the collar 33, so that the adjacent two sets of elastic members 32 are tightly attached to each other and still maintain elastic expansion space, so as to allow the top brace 31 to be compressed.

Referring to fig. 2 and 13, in use, the rivets 91 are placed on the top ends 3111 of the top struts 31, respectively, and the mounting holes 921 of the workpiece 92 are placed on the carrying surface 221 in positions corresponding to the top struts 31, respectively. Subsequently, referring to fig. 12, the operator manually compresses the two click pieces 25 so that when the compression module 1 is to be placed or removed, the two click pieces 25 are simultaneously partially retracted toward each other into the accommodating space 2111 in the respective release positions. The pressing plate 11 is abutted against the top surface of the workpiece 92, and the horizontal height of the hook 122 is lower than that of the clamping block 25. Referring to fig. 11 and 14, the two locking blocks 25 are released, so that the two locking blocks 25 move out of the accommodating space 2111 in opposite directions to move to respective locking positions. The upper edge of the hook 122 is pressed by the pressing end 2511, and the pressing end 2511 is exposed in the pressing notch 1212, so that the positioning of the workpiece 92 during the machining can be maintained, and the pressing plate 11 presses the hook 122 by the pressing end to provide a pre-pressure to the workpiece 92, so that the workpiece 92 can be held on the carrier plate 22 when the press-riveting jig is moved to the press-bonding machine, and in addition, the rivet 91 can be positioned not only in the front-back direction D2 and the left-right direction D3 through the top end 3111 of the top support column 31, but also the hole wall of the mounting hole of the workpiece 92 can be aligned to the top end 3111 by the pre-pressure, so that the rivet 91 is also positioned in the up-down direction D1, and thus the rivet 91 is held on the top support column 31. In addition, after the rivet pressing jig is ready to be placed on the platform of the press machine, the driving assembly (not shown) for pressing against the press module 1 can be controlled by the control unit (not shown), so that the pressing plate 11 presses against the workpiece 92, and the workpiece 92 and the carrier plate 22 are driven by the driving assembly to move toward the base 21, in this case, the elastic member 32 applies an elastic force to the corresponding supporting pillar 31, so that the rivet 91 placed on the top end 3111 is supported upwards and riveted in the corresponding mounting hole 921 as shown in fig. 14, thereby effectively completing the one-time riveting and improving the production efficiency.

It should be noted that even if the sizes of the supporting pillar 31, the base 21 and the supporting plate 22 have a slight error in the production process, for example, 0.01mm, the supporting pillar 31 can compress the elastic member 32 to eliminate the situation of inaccurate riveting. For example, when the error value of the propping rod is +0.01mm, the elastic member 32 sleeved on the propping rod is compressed by a displacement of 0.01mm in the riveting process, so that the rivet 91 is not continuously forced upward to the rivet 91 and the workpiece 92 when the rivet 91 is riveted to a corresponding depth, thereby maintaining the integrity of the rivet 91 and the workpiece 92.

Referring to fig. 15, in another embodiment, two rivets 91 are riveted to different depths by two supporting pillars 31 with different lengths, for example, the supporting pillar 31 with a longer length is used to act on the rivet 91 with a deeper riveting depth, so that the pressing plate 11 can be riveted to the corresponding depth without applying excessive force to the rivet 91 and the workpiece 92.

In other embodiments, the workpiece 92 can be placed by only using a single carrier plate 22, in which case the carrier plate 22 must be designed to be placed on a flat surface and elastically telescopic relative to the flat surface, and when the workpiece 92 is pressed down, the carrier plate 22 is compressed to rivet the rivet placed on the top end 3111 of the top support column 31, and the elastic member 32 is compressed by the top support column 31.

In summary, in the press-riveting jig of the present invention, the elastic member 32 disposed in the buffering space 2131 can support the supporting column 31 and can be compressed by the supporting column 31, so that when the jig with errors is press-riveted, the influence of the errors on the press-riveting precision can be eliminated by the expansion and contraction function of the elastic member 32. Moreover, by combining the plurality of top bracing columns 31 with the telescopic bearing module 2, the riveting operation of the workpiece 91 can be completed at one time by using the press riveting jig, so that the operation capable of eliminating the riveting precision in the prior art can be omitted, the processing time of each workpiece is greatly shortened, the production efficiency of the whole production line is remarkably improved, and the processing cost of the workpiece 92 is greatly reduced.

The above description is only an embodiment of the present invention, and the scope of the present invention should not be limited thereby, and the present invention is still within the scope of the present invention by the simple changes and modifications made according to the claims and the contents of the specification.
