Technical Field

[0001] This invention relates to the field of riveting clutch parts, and more particularly to a device that uses a slider to achieve riveting. Background Technology

[0002] As a crucial component of the clutch, the AMT (Automated Mechanical Transmission) cover structure typically uses rivets to rivet together the multiple parts that make up the AMT cover structure, assembling them into a single unit. However, using traditional riveting dies can lead to a series of problems, such as interference between the die and the product, and insufficient preload, hindering effective riveting and negatively impacting product quality. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a device for riveting by using a slider to push, so as to solve the above-mentioned problem.

[0004] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: A device for riveting by using a slider to push, comprising: an upper die mechanism, an upper pressing mechanism, a lower die mechanism, a sliding riveting mechanism, a lower pressing mechanism, and a plurality of guide mechanisms, wherein the upper die mechanism and the lower die mechanism are respectively arranged at the top and bottom of the guide mechanisms, the upper pressing mechanism is arranged in the middle of the upper die mechanism, the sliding riveting mechanism is arranged around the upper pressing mechanism and is arranged at the bottom of the upper die mechanism, and the lower pressing mechanism is arranged in the middle of the lower die mechanism and corresponds to the upper pressing mechanism and the sliding riveting mechanism.

[0005] The beneficial effects of this invention are: with the cooperation of an external hydraulic press, sufficient pressure can be applied to move the upper mold mechanism, the upper pressing mechanism, and the sliding riveting mechanism downward, pressing the diaphragm spring that makes up the AMT cover tightly onto the lower mold mechanism. During this process, the sliding riveting mechanism contacts the lower pressing mechanism and undergoes lateral displacement, bending the support disc tongue that makes up the AMT cover. This allows the support disc tongue, diaphragm spring, clutch cover, and wave spring that make up the AMT cover to fit tightly together to achieve riveting, improving work efficiency while reducing labor intensity and avoiding interference between the product and the mold.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Further, the upper die mechanism includes: an upper die fixing plate, an upper backing plate, an upper die base, and a first connecting member for fixedly connecting the upper die fixing plate, the upper backing plate, and the upper die base. The upper die fixing plate, the upper backing plate, and the upper die base are all annular plate-like structures. The upper die fixing plate and the upper die base are correspondingly arranged at the top and bottom of the upper backing plate respectively. The first connecting member passes through the upper backing plate and is screwed to the upper die fixing plate and the upper die base.

[0008] The beneficial effect of adopting the above further scheme is that the upper die mechanism is beneficial to fixing the upper pressing mechanism and the sliding riveting mechanism, thereby driving the upper pressing mechanism and the sliding riveting mechanism to move up and down.

[0009] Further, a plurality of guide pillar holes are provided on the upper die base, and the guide pillar holes are through holes.

[0010] The beneficial effect of adopting the above further scheme is that the guide pillar holes are beneficial for the guide pillars in the guiding mechanism to pass through during the process of the overall downward displacement of the upper die mechanism, the upper pressing mechanism, and the moving riveting mechanism, and guiding the downward movement of the upper die mechanism, the upper pressing mechanism, and the moving riveting mechanism.

[0011] Further, the guiding mechanism includes guide pillars and two guide sleeves. The guide sleeves are annular structures. The two guide sleeves are correspondingly arranged on the bottom surface of the upper die base and the lower die mechanism respectively. The upper and lower ends of the guide pillar correspondingly pass through the two guide sleeves, and the guide pillar is adapted to the guide pillar hole.

[0012] The beneficial effect of adopting the above further scheme is that the cooperation of the guide pillars and the guide sleeves is beneficial for the upper die mechanism, the upper pressing mechanism, and the moving riveting mechanism to move towards the lower die mechanism and the lower pressing mechanism along the set path, improving the accuracy of riveting and pressing.

[0013] Further, the upper pressing mechanism includes: a nitrogen spring cover plate, a nitrogen spring, and a diaphragm upper pressing head. The diaphragm upper pressing head is an inverted "Ji" - shaped block structure. The diaphragm upper pressing head is hung at the top of the upper die fixing plate, and the bottom end protrudes downward from the bottom surface of the upper die fixing plate. The upper and lower ends of the nitrogen spring are fixedly connected to the nitrogen spring cover plate and the diaphragm upper pressing head respectively. The nitrogen spring cover plate is screwed to the upper die base.

[0014] The beneficial effect of adopting the above further scheme is that the diaphragm upper pressing head is beneficial for pressing and shaping the diaphragm spring that is warped upward in the initial state. The nitrogen spring cover plate and the nitrogen spring are beneficial for providing a certain buffering effect during the downward pressing process of the diaphragm upper pressing head, and at the same time preventing the diaphragm upper pressing head from having a large upward displacement in the upper die mechanism, thus avoiding punching out of the upper die mechanism.

[0015] Furthermore, the sliding riveting mechanism includes: multiple flanging sliders, multiple rollers, multiple spring pressure plates, multiple return springs, multiple slider pressure plates, and multiple pressure heads; the flanging sliders are wedge-shaped structures, the multiple rollers are respectively disposed on the inclined surfaces of the multiple flanging sliders, the multiple slider pressure plates are plate-shaped structures wrapped around the bottom surface of the upper mold fixing plate, the bottom end of the upper mold fixing plate is provided with multiple slider mounting grooves, the multiple slider mounting grooves and the multiple slider pressure plates are alternately arranged, the multiple flanging sliders are slidably disposed in the multiple slider mounting grooves one by one, the multiple return springs are disposed in the multiple slider mounting grooves one by one at the end near the outer diameter of the upper mold fixing plate, the multiple spring pressure plates are plate-shaped structures disposed in the multiple slider mounting grooves one by one at the end near the outer diameter of the upper mold fixing plate, and are disposed in the bottom end of the multiple return springs one by one, the pressure heads are rod-shaped structures, and the multiple pressure heads are wrapped around and vertically installed on the bottom end of the upper mold fixing plate.

[0016] The beneficial effects of adopting the above-mentioned further solution are as follows: When the flanging slider slides in the slider mounting groove toward the end near the outer diameter of the upper mold fixing plate, it is beneficial to use the side of the flanging slider to bend the protruding support disc tongue, thereby riveting and fixing the diaphragm spring, clutch cover and wave spring together; the roller is beneficial to make the flanging slider slide displacement when it contacts the pressing mechanism; the return spring is beneficial to compress and accumulate elastic force when the flanging slider is displaced, and push the flanging slider back to the initial state after riveting is completed; the spring pressure plate is beneficial to limit the position of the return spring in the slider mounting groove and prevent the return spring from falling off.

[0017] Furthermore, the lower mold mechanism includes: a lower mold base, a lower pad, a lower mold fixing plate, a diaphragm pressing head, and a second connecting member for fixing the lower mold base, the lower pad, and the diaphragm pressing head. The lower mold fixing plate and the diaphragm pressing head are both annular plate structures. The diaphragm pressing head is sleeved on the outside of the lower mold fixing plate. The top and bottom ends of the lower pad are connected to the diaphragm pressing head and the lower mold base respectively. The second connecting member passes through the diaphragm pressing head and the lower pad and is screwed to the lower mold base.

[0018] The beneficial effects of adopting the above-mentioned further solution are: the lower die mechanism is conducive to fixing the lower pressing mechanism and positioning the workpiece to be riveted.

[0019] Furthermore, the pressing mechanism includes: multiple support blocks, a central hole limiting block, multiple cover positioning pins, and multiple cylindrical spiral compression springs. The central hole limiting block is a block structure with a T-shaped longitudinal cross-section and is located in the middle of the lower mold fixing plate. The support block is a wedge-shaped structure with an inclined surface corresponding to the inclined surface of the flange slider. Multiple support blocks are wound around the lower mold fixing plate and correspond one-to-one with multiple flange sliders. Multiple cover positioning pins are wound around the lower pad plate and are arranged around the diaphragm pressing head. The cylindrical spiral compression springs pass through the lower pad plate and are connected to the lower mold fixing plate and the lower mold base one-to-one with their top and bottom ends.

[0020] The beneficial effects of adopting the above-mentioned further solutions are as follows: the support block facilitates the downward and outward displacement of the flanging slider along the inclined surface of the support block after contacting the roller on the inclined surface of the flanging slider, thereby realizing the bending and riveting of the support disc tongue; the center hole limiting block helps to limit the displacement of the pressure head on the diaphragm, avoiding damage to the lower die mechanism caused by the continuous downward pressure of the pressure head on the diaphragm; the cover positioning pin helps to position the clutch cover to be riveted; and the cylindrical helical compression spring helps to provide a certain buffer for the riveting process.

[0029] The principles and features of the present invention are described below. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0030] like Figure 1 and Figure 2 As shown, a riveting device using a slider includes: an upper die mechanism 1, an upper pressing mechanism 2, a lower die mechanism 3, a sliding riveting mechanism 4, a lower pressing mechanism 5, and multiple guide mechanisms 6. The upper die mechanism 1 and the lower die mechanism 3 are respectively arranged at the top and bottom of the guide mechanisms 6. The upper pressing mechanism 2 is arranged in the middle of the upper die mechanism 1. The sliding riveting mechanism 4 is arranged around the upper pressing mechanism 2 and is arranged at the bottom of the upper die mechanism 1. The lower pressing mechanism 5 is arranged in the middle of the lower die mechanism 3 and corresponds to the upper pressing mechanism 2 and the sliding riveting mechanism 4.

[0031] It should be noted that this invention requires the use of an external hydraulic press to apply pressure during operation.

[0032] In a preferred embodiment of the present invention, such as Figure 5 and Figure 6 As shown, the component to be riveted is an AMT cover, which consists of multiple support tongues 7, diaphragm springs 8, clutch covers 9, and wave springs 10. The diaphragm springs 8, clutch covers 9, and wave springs 10 are all annular structures. The support tongues 7 pass through the diaphragm springs 8, clutch covers 9, and wave springs 10 sequentially from bottom to top. Before operation, the support tongues 7, diaphragm springs 8, clutch covers 9, and wave springs 10 need to be positioned on the lower die mechanism 3.

[0033] The beneficial effects of this invention are: with the cooperation of an external hydraulic press, sufficient pressure can be applied to move the upper mold mechanism, the upper pressing mechanism, and the sliding riveting mechanism downward, pressing the diaphragm spring that makes up the AMT cover tightly onto the lower mold mechanism. During this process, the sliding riveting mechanism contacts the lower pressing mechanism and undergoes lateral displacement, bending the support disc tongue that makes up the AMT cover. This allows the support disc tongue, diaphragm spring, clutch cover, and wave spring that make up the AMT cover to fit tightly together to achieve riveting, improving work efficiency while reducing labor intensity and avoiding interference between the product and the mold.

[0034] Preferred, such as Figure 1 and Figure 2 As shown, the upper mold mechanism 1 includes: an upper mold fixing plate 11, an upper pad plate 12, an upper mold base 13, and a first connecting member 14 for fixing the upper mold fixing plate 11, the upper pad plate 12, and the upper mold base 13. The upper mold fixing plate 11, the upper pad plate 12, and the upper mold base 13 are all annular plate structures. The upper mold fixing plate 11 and the upper mold base 13 are respectively disposed at the top and bottom ends of the upper pad plate 12. The first connecting member 14 passes through the upper pad plate 12 and is screwed to the upper mold fixing plate 11 and the upper mold base 13.

[0035] It should be noted that, in a preferred embodiment of the present invention, the first connecting member 14 is a bolt or screw; the inner diameter of the upper pad 12 is smaller than the inner diameter of the upper mold fixing plate 11, which is beneficial for the assembly of the pressure head 23 on the diaphragm; the upper mold fixing plate 11, the upper pad 12 and the upper mold base 13 are coaxially arranged.

[0036] The advantages of adopting the above preferred solution are: the upper mold mechanism is conducive to fixing the upper pressing mechanism and the sliding riveting mechanism, thereby driving the fixed upper pressing mechanism and the sliding riveting mechanism to move up and down.

[0037] Preferred, such as Figure 1 and Figure 2 As shown, the upper mold base 13 is provided with a plurality of guide post holes 131, and the guide post holes 131 are through holes.

[0038] The beneficial effect of adopting the above preferred scheme is that the guide post hole is conducive to the guide post in the guiding mechanism passing through during the overall downward displacement of the upper mold mechanism, the upper pressing mechanism and the moving riveting mechanism, so as to guide the downward movement of the upper mold mechanism, the upper pressing mechanism and the moving riveting mechanism.

[0039] Preferred, such as Figure 1 and Figure 2As shown, the guiding mechanism 6 includes a guide post 61 and two guide sleeves 62. The guide sleeve 62 is of an annular structure. The two guide sleeves 62 are correspondingly arranged on the bottom surface of the upper die holder 13 and the lower die mechanism 3 respectively. The upper and lower ends of the guide post 61 pass through the two guide sleeves 62 correspondingly, and the guide post 61 is adapted to the guide post hole 131.

[0040] It should be noted that: since the upper die mechanism 1 of the present invention needs to be installed on a hydraulic press during use, so Figure 1 in the state shown, before the present invention is used, the upper die mechanism 1, the upper pressing mechanism 2 and the sliding riveting mechanism 4 will not descend under the action of gravity. Then correspondingly Figure 1 the guide post 61 will not pass through the guide post hole 131 in the state shown;

[0041] In a preferred embodiment of the present invention, there may also be only one guide sleeve 62 arranged on the bottom surface of the upper die holder 13, and the bottom end of the guide post 61 is directly connected to the lower die holder 31.

[0042] The beneficial effect of adopting the above preferred solution is that the cooperation of the guide post and the guide sleeve is beneficial to making the upper die mechanism, the upper pressing mechanism and the moving riveting mechanism move towards the lower die mechanism and the lower pressing mechanism along the set path, improving the accuracy of riveting and pressing.

[0043] Preferably, as Figure 1 and Figure 2 shown, the upper pressing mechanism 2 includes: a nitrogen spring cover plate 21, a nitrogen spring 22 and a diaphragm upper pressing head 23. The diaphragm upper pressing head 23 is of an inverted "J" - shaped block structure. The diaphragm upper pressing head 23 is hung at the top end of the upper die fixing plate 11, and the bottom end protrudes downward from the bottom surface of the upper die fixing plate 11. The upper and lower ends of the nitrogen spring 22 are fixedly connected to the nitrogen spring cover plate 21 and the diaphragm upper pressing head 23 correspondingly, and the nitrogen spring cover plate 21 is screwed to the upper die holder 13.

[0044] The beneficial effect of adopting the above preferred solution is that the diaphragm upper pressing head is beneficial to pressing and shaping the diaphragm spring that warps upward in the initial state. The nitrogen spring cover plate and the nitrogen spring are beneficial to providing a certain buffering effect for the diaphragm upper pressing head during the downward pressing process, and at the same time preventing the diaphragm upper pressing head from having a large upward displacement in the upper die mechanism, thus causing it to break out of the upper die mechanism.

[0045] Preferably, as Figures 1 to 4As shown, the sliding riveting mechanism 4 includes: multiple flanging sliders 41, multiple rollers 42, multiple spring pressure plates 43, multiple return springs 44, multiple slider pressure plates 45, and multiple pressure heads 46; the flanging sliders 41 have a wedge-shaped structure, the multiple rollers 42 are respectively disposed on the inclined surfaces of the multiple flanging sliders 41, the multiple slider pressure plates 45 are plate-shaped structures wrapped around the bottom surface of the upper mold fixing plate 11, the bottom end of the upper mold fixing plate 11 is provided with multiple slider mounting grooves 111, and the multiple slider mounting grooves 111 and the multiple slider pressure plates 45 are alternately arranged. Multiple flanged sliders 41 are slidably disposed in multiple slider mounting slots 111, and multiple reset springs 44 are disposed in multiple slider mounting slots 111 near the outer diameter of the upper mold fixing plate 11. Multiple spring pressure plates 43 are plate-shaped structures disposed in multiple slider mounting slots 111 near the outer diameter of the upper mold fixing plate 11, and are disposed at the bottom of multiple reset springs 44. The pressure head 46 is a rod-shaped structure, and multiple pressure heads 46 are wound around and vertically installed at the bottom of the upper mold fixing plate 11.

[0046] It should be noted that "alternating arrangement" means that a slider pressure plate 45 is provided between two adjacent slider mounting slots 111, and a slider mounting slot 111 is provided between two adjacent slider pressure plates 45.

[0047] In a preferred embodiment of the present invention, a spring for shock absorption is provided at the connection between the pressure head 46 and the upper mold fixing plate 11.

[0048] The advantages of adopting the above-mentioned preferred solution are as follows: when the flanging slider slides in the slider mounting groove toward the end near the outer diameter of the upper mold fixing plate, it is beneficial to use the side of the flanging slider to bend the protruding support disc tongue, thereby riveting and fixing the diaphragm spring, clutch cover and wave spring together; the roller is beneficial to make the flanging slider slide when it contacts the pressing mechanism; the return spring is beneficial to compress and accumulate elastic force when the flanging slider moves, and push the flanging slider back to the initial state after riveting is completed; the spring pressure plate is beneficial to limit the position of the return spring in the slider mounting groove and prevent the return spring from falling off.

[0049] Preferred, such as Figure 1 and Figure 2As shown, the lower mold mechanism 3 includes: a lower mold base 31, a lower pad 32, a lower mold fixing plate 33, a diaphragm pressing head 34, and a second connecting member 35 for fixing the lower mold base 31, the lower pad 32, and the diaphragm pressing head 34. The lower mold fixing plate 33 and the diaphragm pressing head 34 are both annular plate structures. The diaphragm pressing head 34 is sleeved on the outside of the lower mold fixing plate 33. The top and bottom ends of the lower pad 32 are connected one-to-one to the diaphragm pressing head 34 and the lower mold base 31. The second connecting member 35 passes through the diaphragm pressing head 34 and the lower pad 32 and is screwed to the lower mold base 31.

[0050] It should be noted that, in a preferred embodiment of the present invention, the second connecting member 35 is a bolt or screw.

[0051] The advantages of adopting the above preferred solution are: the lower die mechanism is conducive to fixing the lower pressing mechanism and positioning the workpiece to be riveted.

[0052] Preferred, such as Figure 1 and Figure 2 As shown, the pressing mechanism 5 includes: multiple support blocks 51, a central hole limiting block 52, multiple cover positioning pins 53, and multiple cylindrical spiral compression springs 54. The central hole limiting block 52 is a block structure with a T-shaped longitudinal cross section and is located in the middle of the lower mold fixing plate 33. The support block 51 is a wedge-shaped structure with an inclined surface corresponding to the inclined surface of the flange slider 41. Multiple support blocks 51 are wound around the lower mold fixing plate 33 and correspond one-to-one with multiple flange sliders 41. Multiple cover positioning pins 53 are wound around the lower pad plate 32 and are arranged around the diaphragm pressing head 34. The cylindrical spiral compression springs 54 penetrate the lower pad plate 32 and are connected to the lower mold fixing plate 33 and the lower mold base 31 one-to-one with their top and bottom ends.

[0053] The advantages of adopting the above-mentioned preferred solution are: the support block facilitates the downward and outward displacement of the flanging slider along the inclined surface of the support block after contacting the roller on the inclined surface of the flanging slider, thereby realizing the bending and riveting of the support disc tongue; the center hole limiting block helps to limit the displacement of the pressure head on the diaphragm, avoiding damage to the lower die mechanism caused by the continuous downward pressure of the pressure head on the diaphragm; the cover positioning pin helps to position the clutch cover to be riveted; and the cylindrical helical compression spring helps to provide a certain buffer for the riveting process.

[0054] The working process of the present invention will be described below through an embodiment:

[0055] like Figures 1 to 6As shown, in this embodiment, the support disc tongue 7, diaphragm spring 8, clutch cover 9 and wave spring 10 are riveted. After the diaphragm spring 8 and wave spring 10 are flattened, the parts are tightly fitted together. The pressure reference value of the flattening point of the diaphragm spring 8 is 34500N±1000N, and the pressure reference value of the flattening point of the wave spring 10 is 5000N±500N. Therefore, the preload applied by the hydraulic press needs to be greater than 40000N.

[0056] Before operation, the lower mold mechanism 3 is installed on the worktable of the hydraulic press, and the upper mold mechanism 1 is installed on the slide block of the hydraulic press. Based on the model of the device described in this invention, parts corresponding to the product are obtained, and the parts are assembled according to the product process to form the parts in the state before riveting, such as... Figure 5 As shown, the multiple pin holes on the clutch cover 9 are connected one-to-one with the multiple cover positioning pins 53, and the diaphragm spring 8 is placed on the lower mold fixing plate 33, so that... Figure 5 The support disc tongue 7, diaphragm spring 8, clutch cover 9 and wave spring 10 shown are positioned on the lower mold mechanism 3.

[0057] During operation, the hydraulic equipment is started, and the upper mold mechanism 1, the upper pressing mechanism 2, and the sliding riveting mechanism 4 move downward. During this process, the guide post 61 passes through the guide post hole 131 to guide the displacement of the upper mold mechanism 1, the upper pressing mechanism 2, and the sliding riveting mechanism 4. After moving downward for a period of time, under the pre-pressure applied by the hydraulic press, the pressure head 46 presses against the top of the wave spring 10, and the pressure head 23 on the diaphragm presses against the middle hole limit block 52. The diaphragm spring 8 and the wave spring 10 are both flattened under the pre-pressure. During this process, the roller 42 on the inclined surface of the flanging slider 41 slides against the inclined surface of the support block 51, causing the flanging slider 41 to move outward (towards the outer diameter of the upper mold fixing plate 11). The side of the flanging slider 41 then bends the upwardly protruding support disc tongue 7 by 90 degrees, completing the riveting.

[0058] For different workpieces to be riveted and devices of different specifications, this invention can calculate the height of the flanging slider 41 and the support block 51, simulate the pre-pressing height and the movement trajectory of the flanging slider 41, so that the support disc tongue 7 is subjected to force and flanging bends 90 degrees to achieve riveting, which improves work efficiency, reduces labor intensity, simplifies mold structure, and is applicable to various products in the riveting field.
