[0005] According to the tooling for press riveting of seat slides described in the embodiment of this application, the first feeding part further includes an adjusting member, and the adjusting member is used to adjust the distance between the top of the second feeding member and the top of the first feeding member.

[0006] According to the tooling for press riveting of seat slides described in the embodiment of this application, the second feeding member can move along the axial direction of the first feeding member, and part of the adjusting member presses against the second feeding member. The adjusting member is threadedly connected to the first feeding member, so that the adjusting member can adjust the distance between the top of the second feeding member and the top of the first feeding member along the axial direction of the first feeding member.

[0007] For the tooling for riveting of a seat slide rail according to an embodiment of the present application, the first feeding member includes a body column and a convex column connected to each other.

[0032] As shown Figure 9 The seat slide rail 700 shown in the figure includes a slide rail body 710 and a reinforcing plate 720. The reinforcing plate 720 is located at the middle position outside the slide rail body 710. The slide rail body 710 and the reinforcing plate 720 are riveted together by two rodless rivets 711, and at least three rod rivets 712 are riveted on the slide rail body 710. The rod rivets 712 are used for connecting the seat slide rail 700 with other automotive accessories. When the existing rodless rivets 711 are riveted, due to the poor tooling design of the seat slide rail 700, the rodless rivets 711 are likely to shift during riveting and cannot be pressed and riveted properly. Moreover, due to the unreasonable structural design for positioning the rod rivets 712, the rod parts of the rod rivets 712 are likely to be deformed and stuck on the tooling during press riveting. Among them, Figure 10 FIG. is a schematic structural diagram of the rod rivet 712 in the embodiment of the present application, Figure 11 FIG. is a schematic structural diagram of the rodless rivet 711 in the embodiment of the present application.

[0033] Referring to Figures 1 to 4 , the embodiment of the present application provides a tooling for press riveting the seat slide rail 700, which optimizes the positioning structure of the rivets. Specifically, the tooling for press riveting the seat slide rail 700 of the present application includes an operation platform 101, and a first positioning member 120, a plurality of second positioning members 110, a first material feeding part 300, a second material feeding part 400 and a pre-tightening part 200 are arranged on the operation platform 101.

[0034] The second positioning member 110 is used for placing the slide rail body 710 and the reinforcing plate 720. Specifically, in the embodiment of the present application, a total of four second positioning members 110 are provided. The two second positioning members 110 in the middle are mainly used for placing the reinforcing plate 720. After the slide rail body 710 and the reinforcing plate 720 are stacked, the second positioning member 110 can also limit the slide rail body 710. To ensure that the slide rail body 710 and the reinforcing plate 720 will not shift during press riveting and cause press riveting deviation, the second positioning member 110 has a placement groove for placing the slide rail body 710 and the reinforcing plate 720, and the offset between the slide rail body 710 and the reinforcing plate 720 is restricted through the placement groove. The first positioning member 120 is used for positioning the slide rail body 710. In the embodiment of the present application, a positioning hole is respectively arranged at both ends of the slide rail body 710. The first positioning member 120 is a positioning pin adapted to the positioning hole of the slide rail body 710. The complete positioning of the slide rail body 710 is realized through the cooperation of the positioning pin and the placement groove. The setting positions of the first positioning member 120 correspond to the positions of the positioning holes one by one, which is convenient for the quick placement of the slide rail body 710. Multiple types of positioning members can be set according to different seat slide rails 700, so as to be able to replace the corresponding positioning members according to different models of seat slide rails 700.

[0035] Among them, the pre-tightening part 200 is used to press the positioned slide rail body 710. Specifically, the pre-tightening part 200 is used to press the end of the positioned slide rail body 710, that is, both ends of the slide rail body 710 are pressed by the pre-tightening part 200.

[0036] The first feeding part 300 corresponds to the riveting position of the non-threaded rivet 711 on the slide rail body 710, and the second feeding part 400 corresponds to the riveting position of the threaded rivet 712 on the slide rail body 710. The first feeding part 300 includes a first feeding member 310 and a second feeding member 330. The second feeding member 330 is sleeved on the first feeding member 310, and a resilient member 340 is arranged between the second feeding member 330 and the first feeding member 310, so that the part of the second feeding member 330 higher than the first feeding member 310 forms a card slot 331 for positioning the non-threaded rivet 711 with the first feeding member 310. The second feeding part 400 has a positioning groove 411 for positioning the threaded rivet 712. Specifically, the second feeding part 400 includes a positioning seat 410, and the positioning groove 411 is arranged at the top of the positioning seat 410.

[0037] After assembling each component and adjusting the depth of the card slot 331 to fit the non-threaded rivet 711 to be riveted currently, during use, first position the non-threaded rivet 711 in the card slot 331 and position the threaded rivet 712 in the positioning groove 411 to achieve effective positioning of the non-threaded rivet 711 and avoid affecting the positioning of the non-threaded rivet 711 when placing the slide rail body 710 and the reinforcing plate 720. In addition, placing the non-threaded rivet 711 first is beneficial for preliminary positioning of the reinforcing plate 720. Then, place the reinforcing plate 720 and the slide rail body 710 on the second positioning member 110 in sequence and perform final positioning through the first positioning member 120, so that the threaded rivet 712 and the non-threaded rivet 711 are accurately located in the holes to be riveted. Before riveting, the slide rail body 710 is pressed tightly by the pre-tightening part 200 to ensure that there will be no large displacement during the riveting process. Among them, the riveting of the seat slide rail 700 is carried out by a riveting device. Figure 1 and Figure 3 Only the riveting part 500 of the riveting device is shown. Since the resilient member 340 is arranged between the second feeding member 330 and the first feeding member 310, the formed card slot 331 can effectively position the non-threaded rivet 711. During riveting, the second feeding member 330 is compressed to be flush with the first feeding member 310 to ensure normal riveting of the non-threaded rivet 711, effectively solving the positioning problem of the non-threaded rivet 711. By appropriately expanding the width of the positioning groove 411, the situation that the rod part of the threaded rivet 712 is deformed and embedded in the positioning groove 411 during riveting of the threaded rivet 712 can be avoided. In the embodiment of the present application, the problem can be effectively solved when the width of the positioning groove 411 is 0.3 - 0.7 mm larger than the diameter of the rod part of the threaded rivet 712.

[0038] Further, as Figure 5and Figure 6 As shown in Figure 6 , the first feeding part 300 further includes an adjusting member 320 for adjusting the distance between the top of the second feeding member 330 and the top of the first feeding member 310, so as to appropriately adjust the depth of the card slot 331 according to the length of different stemless rivets 711, ensure that the top of the second feeding member 330 does not affect the placement of the reinforcing plate 720 before riveting, and enable part of the stemless rivet 711 to enter the riveting holes of the reinforcing plate 720 and the slide rail body 710 to achieve preliminary positioning.

[0039] Furthermore, the second feeding member 330 can move along the axial direction of the first feeding member 310. Part of the adjusting member 320 presses against the second feeding member 330, and the adjusting member 320 is threadedly connected to the first feeding member 310, so that the adjusting member 320 can adjust the distance between the top of the second feeding member 330 and the top of the first feeding member 310 along the axial direction of the first feeding member 310. During adjustment, the depth of the card slot 331 can be quickly adjusted by screwing the adjusting member 320, which is convenient for adjustment.

[0040] In some embodiments, the first feeding member 310 includes a main body column and a convex column 311 connected to each other. The diameter of the main body column is greater than that of the convex column 311, so that a step is formed at the connection between the main body column and the convex column 311. The second feeding member 330 is sleeved on the convex column 311, and both ends of the elastic member 340 abut against the second feeding member 330 and the main body column respectively. Specifically, the elastic member 340 is a spring, the spring is sleeved on the convex column 311, one end of the spring abuts against the second feeding member 330, and the other end abuts against the step, ensuring that the second feeding member 330 can be retracted to be flush with the first feeding member 310 during riveting.

[0041] In some other embodiments, the adjusting member 320 is in a circular ring shape. One end of the adjusting member 320 is threadedly connected to the main body column, and the other end of the adjusting member 320 has a first limiting ring 321. A second limiting ring 332 is provided on the outer side of the bottom of the second feeding member 330, and the first limiting ring 321 presses against the second limiting ring 332. Specifically, internal threads are provided on the inner side of one end of the adjusting member 320, external threads matching the internal threads are provided on the outer side of the main body column, the edge of the other end of the adjusting member 320 extends towards the center position of the adjusting member 320 to form the first limiting ring 321, the second limiting ring 332 extends outwards on the outer side of the bottom of the second feeding member 330, the second limiting ring 332 is on the movement path of the first limiting ring 321, and the second limiting ring 332 is between the first limiting ring 321 and the step. The configuration of the first limiting ring 321 and the second limiting ring 332 can prevent the second feeding member 330 from disengaging from the convex column 311 under the action of the spring.

[0042] To ensure the detection of the presence or absence of the stemmed rivet 712 in the positioning groove 411 before riveting, as Figure 7 amountFigure 8 As shown, the second discharging part 400 is further provided with a first sensor 420 for detecting the rod part of the solid shank rivet 712.

[0043] To ensure the accurate placement of the reinforcing plate 720 before riveting, a second sensor 130 is arranged on the working platform 101. The second sensor 130 is used to sense the reinforcing plate 720 or the slide rail body 710 in the placement groove.

[0044] In some other preferred embodiments, the tooling for riveting the seat slide rail 700 further includes a lifting structure 600. The lifting structure 600 includes a first cylinder 610 and a top plate 620. The first cylinder 610 drives the top plate 620 to perform a linear reciprocating motion, so that the top plate 620 can lift the riveted seat slide rail 700 away from the placement groove. Among them, the initial position of the top plate 620 is lower than the bottom of the placement groove.

[0045] In some other embodiments, the pre-tightening part 200 is arranged on one side of the placement groove. The pre-tightening part 200 includes a second cylinder 210 and a pre-tightening plate 220. The second cylinder 210 is fixed on the working platform 101. The pre-tightening plate 220 is rotatably arranged on the working platform 101. One end of the pre-tightening plate 220 is provided with a flexible pressing block 230, and the other end is hinged to the cylinder rod of the second cylinder 210. The flexible pressing block 230 can be flipped above the positioned slide rail body 710. Before pressing, the flexible pressing block 230 is flipped away from the direct top of the placement groove under the action of the second cylinder 210. When pressing is required, the flexible pressing block 230 is flipped to press and position the slide rail body 710 in the placement groove. Among them, the flexible pressing block 230 is made of rubber to avoid over-prepressing and damaging the surface of the slide rail body 710.

[0046] The embodiments of the present application have been described in detail above in conjunction with the accompanying drawings. However, the present application is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the purpose of the present application.
