Description

Technical Field

[0001] The utility model relates to the field of crimping, in particular to a crimping device. Background Art

[0002] Synchronous pulleys are widely used as a common component in existing mechanical transmission devices. Synchronous pulleys with annular ribs on both sides of the wheel body can prevent the transmission belt from falling off and are more widely used in mechanical transmission devices.

[0003] At present, when manufacturing synchronous pulleys with annular ribs, riveting is usually used to fix the annular ribs to the side of the synchronous pulley through metal deformation. However, most existing riveting devices are single-sided riveting structures, which can only perform riveting processing on one side of the wheel body first. After the riveting of the annular ribs on one side of the wheel body is completed, the staff still needs to turn the wheel body over to perform riveting processing on the other side of the wheel body. The manufacturing process is relatively cumbersome, the production efficiency is low, and the labor intensity of the staff is high. In addition, when processing, the staff usually needs to manually place the wheel body to be processed in the corresponding processing position, and manually remove it after the crimping is completed. In particular, when it is necessary to process small batches of synchronous pulleys with multiple specifications, it is also necessary to manually replace the processing jig. As mentioned above, there are technical problems in the prior art in the process of processing synchronous pulleys, such as low production efficiency and high labor intensity of the staff. Utility Model Content

[0004] The utility model aims to provide a crimping device, so as to at least solve or alleviate the problems of low production efficiency and high labor intensity of workers in the manufacturing process of synchronous pulleys in the prior art.

[0005] The utility model provides a crimping device for crimping an assembly. The assembly includes a wheel-shaped component and a pair of annular rib components 202, 203. The wheel-shaped component has two opposite side portions along its rotation axis, and the pair of annular rib components 202, 203 are respectively sleeved on the two side portions. The crimping device includes a conveying component, which is configured to convey the assembly to a processing position. The pressure component includes a bracket component and at least two pairs of pressure components of different specifications mounted on the bracket component, and each pair of pressure components is arranged oppositely in a form that can be relatively close to / far away from each other. The pressure component is movable so that the assembly located at the processing position is between the pair of pressure components, and when the pair of pressure components are relatively close to each other, the pair of pressure components squeeze the two side portions respectively, and fix the pair of annular rib components 202, 203 to the two side portions respectively.

[0006] According to the above technical solution, the conveying assembly can automatically transport the assembly to the processing position, eliminating the need for manual placement. The pressure assembly simultaneously presses both sides of the assembly at the processing position, securing a pair of annular ribs 202 and 203 to each side without flipping the assembly over, effectively improving production efficiency and reducing worker labor. The movable pressure assembly allows selection between two pairs of pressure components of different specifications, positioning the assembly to be processed between the selected pair of pressure components. This facilitates improved efficiency in processing small batches of multi-specification synchronous pulleys.

[0007] In the crimping device of an optional technical solution of the present invention, the conveying assembly includes a strip-shaped receiving groove capable of accommodating and arranging a plurality of assemblies. A pushing member is movable within the strip-shaped receiving groove and pushes the assemblies located therein out of the first end of the strip-shaped receiving groove. The transition table includes a first table portion and a second table portion, the first table portion abutting the first end, and the second table portion abutting the processing position. The clamping member is capable of clamping the assembly located in the first table portion and pushing the assembly to the processing position via the second table portion.

[0008] According to the above preferred technical solution, multiple assemblies to be processed can be pre-placed through the strip-shaped receiving groove, which reduces the loading time of the assemblies. During processing, the assemblies to be crimped can be automatically pushed to the corresponding processing positions one by one for crimping through the cooperation of the pushing member and the clamping member, which effectively improves production efficiency and reduces the labor intensity of workers.

[0009] In the crimping device of an optional technical solution of the present invention, the conveyor assembly further includes a conveyor belt extending in the same direction as the strip-shaped receiving groove. The transition platform further includes a third surface portion that interfaces with the conveyor belt. The clamping member can clamp the assembly in the processing position and push the assembly onto the conveyor belt through the second surface portion, the first surface portion, and the third surface portion.

[0010] According to the above preferred technical solution, the conveyor belt and the strip-shaped receiving groove extend in the same direction, making the overall layout more compact and occupying less space. Furthermore, after the assembly is crimped at the processing position, the clamping member automatically pushes the crimped assembly onto the conveyor belt via the transition table, eliminating the need for manual removal by workers, further improving production efficiency and reducing worker labor.

[0011] In the crimping device of the optional technical solution of the present invention, the conveying component conveys the assembly to the processing position in a manner such that the rotation axis direction of the assembly is parallel to the direction of gravity.

[0012] According to the above preferred technical solution, by keeping the rotation axis direction of the assembly parallel to the direction of gravity during the clamping and pushing process, the assembly can be accurately and smoothly transported to the processing position.

[0013] In an optional technical solution of the present invention, the crimping device further includes a mounting plate member, wherein the processing position is formed on the mounting plate member. The mounting plate member has a through hole. When the assembly is placed in the processing position, the rotation axis of the assembly is parallel to the direction of gravity, and a side portion of the assembly is exposed downward through the through hole.

[0014] According to the above preferred technical solution, by making the rotation axis direction of the assembly parallel to the gravity direction and exposing one side of the assembly downward through the through hole, a pair of oppositely arranged pressure components can be accurately aligned with the two sides of the assembly for double-sided pressing.

[0015] In the crimping device of the optional technical solution of the present invention, each pair of pressure components includes an upper pressure component and a lower pressure component. The upper pressure component can press the side of the assembly away from the through hole, and the lower pressure component can press the side of the assembly exposed from the through hole.

[0016] According to the above preferred technical solution, the upper and lower pressure components arranged opposite to each other can simultaneously pressurize both sides of the assembly without turning over during the pressurization process, thereby improving production efficiency and reducing the labor intensity of the staff.

[0017] In the crimping device of the optional technical solution of the present invention, the lower end portion of the upper pressure component has a plurality of circumferentially distributed upper pressure teeth, and the upper end portion of the lower pressure component has a plurality of circumferentially distributed lower pressure teeth.

[0018] According to the above preferred technical solution, the circumferentially distributed upper pressing teeth and lower pressing teeth are conducive to squeezing the circumferences of the two side portions close to the annular rib components, thereby achieving a stable crimping connection.

[0019] In the crimping device of the optional technical solution of the present invention, the crimping device further includes a force-bearing terminal component, and the force-bearing terminal component is configured to abut against the lower end portion of the lower pressure-applying component.

[0020] According to the above preferred technical solution, by providing a force-bearing terminal component, the force borne by the lower pressure component can be transmitted to the force-bearing terminal component, and basically not transmitted to the bracket component, thereby avoiding damage to the bracket component.

[0021] In the crimping device of the optional technical solution of the present invention, the force-bearing terminal component has an abutting surface and a guide surface connected to the abutting surface, and the guide surface is tilted so that the side close to the abutting surface is higher than the side away from the abutting surface.

[0022] According to the above preferred technical solution, by providing the inclined guide surface, the end of the lower pressure member can be gradually lifted until it contacts the contact surface, thereby ensuring the reliability of the contact between the end of the lower pressure member and the force-bearing terminal member.

[0023] In the crimping device of the optional technical solution of the present invention, the placing plate component has a placing surface in contact with the annular retaining edge component, and a limiting protrusion arranged around the placing surface.

[0024] According to the above preferred technical solution, the assembly is limited by the supporting surface contacting the bearing annular rib component and the limiting protrusion, which can avoid the assembly from deflecting and facilitate alignment and crimping.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Figure 1 This is a structural diagram of a crimping device according to an embodiment of the present invention. Figure 2 This is a structural diagram of an assembly according to an embodiment of the present invention.

[0032] The crimping device 100 of this embodiment is used to crimp the assembly 200. Figure 2 As shown, the assembly 200 includes a wheel-shaped component 201 and a pair of annular rib components 202, 203. Specifically, the pair of annular rib components 202, 203 include a first annular rib component 202 and a second annular rib component 203. The wheel-shaped component 201 has two opposite sides 2011, 2012 along its rotation axis. Specifically, the two opposite sides 2011, 2012 include a first side portion 2011 (not shown). Figure 2 As shown in the reference Figure 4 ) and the second side portion 2012. A pair of annular rib components 202, 203 are respectively sleeved on the two side portions 2011, 2012, that is, the first annular rib component 202 is sleeved on the first side portion 2011, and the second annular rib component 203 is sleeved on the second side portion 2012.

[0033] The crimping device 100 includes a conveying component and a pressing component. As a specific example, the conveying component may include a strip receiving groove 11, a pushing member 12, transition platforms 131, 132 and a clamping member 14. The conveying component is configured to convey the assembly 200 to a processing position. As a specific example, refer to Figure 3 The pressure assembly includes a bracket member 20 and two pairs of pressure members of different specifications mounted on the bracket member 20: a first upper pressure member 41 and a first lower pressure member 51, and a second upper pressure member 42 and a second lower pressure member 52. The first upper pressure member 41 and the first lower pressure member 51 are arranged in a manner that allows them to move closer or farther away from each other. Similarly, the second upper pressure member 42 and the second lower pressure member 52 are arranged in a manner that allows them to move closer or farther away from each other.

[0034] It is understood that the structure of the conveying assembly is not particularly limited; as long as it can transport the assembly to the processing position, it falls within the scope of the conveying assembly described in this utility model. Although in the illustrated embodiment, the processing position is the location of the mounting surface 33, this application is not limited to this. Any structure used to place or secure the assembly 200 during the crimping process falls within the scope of the processing position described in this utility model. Although this embodiment only describes a pressure assembly having two pairs of pressure components of different specifications, it is understood that the number of pairs of pressure components can also be three or more pairs without particular limitation.

[0035] The pressing assembly can be moved so that the assembly 200 located at the processing position is interposed between the first upper pressing member 41 and the first lower pressing member 51, or between the second upper pressing member 42 and the second lower pressing member 52. Figure 4 In this embodiment, the assembly 200 is described as being located between the first upper pressure member 41 and the first lower pressure member 51. When the first upper pressure member 41 and the first lower pressure member 51 are relatively close to each other, the first upper pressure member 41 and the first lower pressure member 51 respectively press the second side portion 2012 and the first side portion 2011, thereby fixing the second annular rib member 203 and the first annular rib member 202 to the second side portion 2012 and the first side portion 2011, respectively.

[0036] The conveying component can automatically convey the assembly 200 to be processed to the processing position without manual placement, and then the pressure component can simultaneously crimp the two side parts 2011 and 2012 of the assembly 200 located at the processing position. Without turning it over, a pair of annular retaining edge components 202 and 203 can be fixed to the two side parts 2011 and 2012 respectively, which effectively improves production efficiency and reduces the labor intensity of workers.

[0037] refer to Figure 1 The conveying assembly includes a strip-shaped receiving groove 11, a pusher 12, transition platforms 131 and 132, and a clamping member 14. The strip-shaped receiving groove 11 can accommodate and arrange multiple assemblies 200. The pusher 12 can move within the strip-shaped receiving groove 11 and push the assemblies 200 located therein out of the first end of the strip-shaped receiving groove 11.

[0038] refer to Figure 1 In this embodiment, the pushing member 12 includes a pushing block 121 movably disposed within the strip-shaped receiving groove 11, a sliding guide rail 122 disposed at a side of the strip-shaped receiving groove 11 and extending in the same direction as the strip-shaped receiving groove 11, and a sliding plate 123 movably disposed on the sliding guide rail 122 and connected to the pushing block 121. By driving the sliding plate 123 to move on the sliding guide rail 122, the pushing block 121 is correspondingly driven to move within the strip-shaped receiving groove 11, thereby pushing out the assembly 200.

[0039] The transition platforms 131 and 132 have a first platform portion 131 and a second platform portion 132. The first platform portion 131 is connected to the first end portion, and the second platform portion 132 is connected to the processing position. The clamping member 14 can clamp the assembly 200 on the first platform portion 131 and push the assembly 200 to the processing position through the second platform portion 132.

[0040] The conveying component can automatically push the assembly 200 to be processed to the corresponding processing position, thereby improving production efficiency and reducing the labor intensity of the staff.

[0041] Meanwhile, in the process of conveying the assembly 200 to the processing position, the conveying component conveys the assembly 200 in a manner such that the rotation axis direction of the assembly 200 is parallel to the gravity direction, thereby being able to convey the assembly 200 to the processing position accurately and smoothly.

[0042] refer to Figure 1 In this embodiment, the conveying assembly further includes a conveying belt 15, which extends in the same direction as the strip-shaped receiving groove 11, making the overall layout of the device more compact and effectively reducing the occupied space.

[0043] In some embodiments, the transition stages 131 and 132 further include a third stage portion (not shown), which interfaces with the conveyor belt 15 and the first stage portion 131. The clamping member 14 can clamp the assembly 200 in the processing position and sequentially push the assembly 200 onto the conveyor belt 15 through the second stage portion 132, the first stage portion 131, and the third stage portion. The provision of the third stage portion facilitates stable movement of the processed assembly 200 onto the conveyor belt 15. However, it will be appreciated that in some embodiments, the purpose of moving the processed assembly 200 onto the conveyor belt 15 can be achieved using only the clamping member 14 without the third stage portion.

[0044] After the assembly 200 is crimped at the processing position, the crimped assembly 200 is automatically pushed to the conveyor belt 15 through the transition tables 131 and 132, without the need for manual removal by workers, further improving production efficiency and reducing labor intensity of workers.

[0045] refer to Figure 1 In this embodiment, the completed assembly 200 is pushed to one end of the conveyor belt 15. A storage box 16 is provided below the other end of the conveyor belt 15 for receiving the completed assembly 200. After the assembly 200 is processed at the processing position, the clamping member 14 cooperates with the transition tables 131 and 132 to automatically and accurately push the assembly 200 to the conveyor belt 15. The conveyor belt 15 then transports the assembly 200 toward the storage box 16, where it is automatically collected and stored.

[0046] Figure 3 1 is a diagram showing the coordinated structure of the pressure-applying assembly, the mounting plate component 30 and the force-bearing terminal component 60 according to an embodiment of the present invention.

[0047] like Figure 3 As shown, in this embodiment, the bracket component 20 of the pressure assembly includes a first plate portion 21 , a second plate portion 22 arranged facing the first plate portion 21 , and a connecting plate portion 23 connecting the first plate portion 21 and the second plate portion 22 .

[0048] The bracket component 20 is arranged in a first direction with two pairs of pressure components of different specifications, namely a first upper pressure component 41 and a first lower pressure component 51 , and a second upper pressure component 42 and a second lower pressure component 52 .

[0049] The first upper pressure member 41 and the first lower pressure member 51 are detachably mounted opposite each other on the bracket member 20. The second upper pressure member 42 and the second lower pressure member 52 are detachably mounted opposite each other on the bracket member 20. The first upper pressure member 41 and the second upper pressure member 42 are mounted on the first plate portion 21, while the second lower pressure member 51 and the second lower pressure member 52 are mounted on the second plate portion 22. This facilitates replacement of the first upper pressure member 41 and the first lower pressure member 51, or the second upper pressure member 42 and the second lower pressure member 52, according to the specifications of the assembly 200 to be processed.

[0050] refer to Figure 3 The crimping device 100 further includes a force-receiving terminal component 60 configured to abut against the lower end of the first lower pressure component 51 or the second lower pressure component 52. Specifically, the bracket component 20 is configured to be driven in a first direction so that one of the first lower pressure component 51 and the second lower pressure component 52 abuts against the force-receiving terminal component 60.

[0051] In this embodiment, the force-bearing terminal component 60 includes an abutting base 61, on which an abutting block is disposed. The abutting block includes an abutting surface 62 and a guide surface 63 connected to the abutting surface 62. The guide surface 63 is tilted such that the side closer to the abutting surface 62 is positioned higher than the side farther from the abutting surface 62. By providing the tilted guide surface 63, the lower end of the first lower pressure component 51 or the second lower pressure component 52 can be gradually raised until it abuts the abutting surface 62. This ensures the reliability of the abutment between the lower end of the first lower pressure component 51 or the second lower pressure component 52 and the force-bearing terminal component 60. Furthermore, due to the provision of the force-bearing terminal component 60, the force exerted on the first lower pressure component 51 or the second lower pressure component 52 is transmitted to the force-bearing terminal component 60, and is substantially not transmitted to the bracket component 20, thereby preventing damage to the bracket component 20.

[0052] It is understood that to ensure that the first upper pressure member 41, the first lower pressure member 51, the second upper pressure member 42, and the second lower pressure member 52 can be easily installed and removed from the bracket member 20, the bracket member 20 is generally suspended, that is, the bracket member 20 cannot withstand excessive pressure. In this case, by providing the force-bearing terminal member 60, both the functionality and stability of the bracket member 20 can be taken into account.

[0053] In other embodiments, the upper pressure component 41 and the lower pressure component 51 may be stably disposed on a force-bearing structure in the crimping device 100 . In this case, the force-bearing terminal component 60 may not be specifically provided.

[0054] Figure 4 It is a front view of the pressure assembly, the mounting plate component 30 and the force-bearing terminal component 60 when the assembly body is loaded according to the embodiment of the present invention.

[0055] like Figure 4 As shown, the crimping device 100 further includes a carrier plate component 30, the processing position being formed on the carrier plate component 30, and the carrier plate component 30 is provided with a through hole. Specifically, the carrier plate component 30 is provided with at least two through holes 31 and 32 of different sizes arranged in correspondence in a first direction, namely a first through hole 31 and a second through hole 32.

[0056] The assembly 200 can be placed at a processing position corresponding to the first through hole 31 or at a processing position corresponding to the second through hole 32. Figure 4 The following description will be made by taking the assembly 200 placed at the processing position corresponding to the first through hole 31 as an example.

[0057] When the assembly 200 is placed in the processing position corresponding to the first through-hole 31, the rotation axis of the assembly 200 is parallel to the direction of gravity. One side of the assembly 200 is exposed downward through the through-hole 31, allowing the first upper pressure member 41 and the first lower pressure member 51, which are arranged opposite each other, to accurately align with the two side portions 2011 and 2012 of the assembly 200 for double-sided pressure bonding.

[0058] Continue to refer Figure 4 The mounting plate member 30 supports the assembly 200 in a manner such that the second side portion 2012 faces away from the mounting plate member 30 and the first side portion 2011 is exposed through the through hole 31. The first upper pressure member 41 can press the second side portion 2012 of the assembly 200 away from the first through hole 31, and the first lower pressure member 51 can press the first side portion 2011 of the assembly 200 exposed from the first through hole 31.

[0059] In this embodiment, the mounting plate member 30 is configured to be movable between a first position A and a second position B in the direction of the rotation axis (refer to Figure 4, the direction indicated by the double-headed arrow is the rotation axis direction of the wheel-shaped component 201, and the loading plate component 30 can move between the first position A and the second position B in the rotation axis direction).

[0060] The first upper pressure member 41 is configured to be driven in the direction of the rotation axis and to press the second side portion 2012, thereby fixing the second annular rib member 203 to the second side portion 2012. The first lower pressure member 51 is configured to press the first side portion 2011, thereby fixing the first annular rib member 202 to the first side portion 2011, when the mounting plate member 30 moves to the second position B. The second position B is closer to the first lower pressure member 51 than the first position A.

[0061] The first upper pressing member 41 and the first lower pressing member 51 arranged opposite to each other can simultaneously press the two side portions 2011 and 2012 of the assembly 200. There is no need to turn over during the press-connection process, which improves production efficiency and reduces labor intensity of workers.

[0062] The lower end portion of the first upper pressure member 41 has a plurality of circumferentially distributed upper pressure teeth 410 , and the upper end portion of the first lower pressure member 51 has a plurality of circumferentially distributed lower pressure teeth 510 .

[0063] The upper pressing teeth 410 and the lower pressing teeth 510 are both matched with the aligned first through holes 31. The circumferential distribution of the upper pressing teeth 410 and the lower pressing teeth 510 facilitates squeezing the circumference of the two side portions 2011 and 2012 close to the annular rib components, so that during double-sided crimping, the first annular rib component 202 and the first side portion 2011, and the second annular rib component 203 and the second side portion 2012 can be stably connected through metal deformation.

[0064] The loading plate component 30 has a loading surface 33 that contacts the annular retaining edge component, and a limiting protrusion 34 arranged around the loading surface 33. A U-shaped groove is formed on the loading plate component 30. The first through hole 31 is located at the arcuate end of the U-shaped groove and is spaced apart from the arcuate end. The loading surface 33 is generally U-shaped and is arranged around the inner side of the U-shaped groove. The loading surface 33 includes straight loading surfaces located on both sides and an arcuate loading surface connecting the straight loading surfaces on both sides. The first through hole 31 is arranged close to the arcuate loading surface.

[0065] When the assembly 200 is placed into the loading plate component 30, the first annular rib component 202 is first supported by the straight loading surfaces on both sides, and finally reaches the position of the first through hole 31. The first annular rib component 202 is supported by the arc loading surface, which facilitates the loading of the assembly 200.

[0066] refer to Figure 4When the first upper pressure member 41 and the first lower pressure member 51 are aligned with the first through-hole 31 in the direction of the rotation axis and the assembly 200 is placed into the loading plate member 30, the first annular retaining member 202 is supported by the loading surface 33, and the assembly 200 is restrained in the retaining protrusion 34. In this position, the assembly 200 is in the processing position, the first side portion 2011 is exposed downward from the first through-hole 31, and the multiple circumferentially distributed lower pressure teeth 510 of the lower pressure end 512 of the first lower pressure member 51 are aligned with the circumference of the first side portion 2011. Simultaneously, the second side portion 2012 and the second annular retaining member 203 mounted on the second side portion 2012 are positioned outside the retaining protrusion 34. The multiple circumferentially distributed upper pressure teeth 410 of the upper pressure end 412 of the first upper pressure member 41 are aligned with the circumference of the first side portion 2011. In this way, both sides of the assembly 200 can be conveniently aligned and pressed at the same time, and the position of the assembly 200 is prevented from being shifted during the pressing process by limiting the position.

[0067] refer to Figure 3 In this embodiment, both ends of the loading plate component 30 in the first direction are provided with fixing assemblies 70. Both ends of the loading plate component 30 in the first direction are Z-shaped plates, and the outwardly protruding portions of the Z-shaped plates are provided with fixing holes and are correspondingly mounted on the connecting blocks 71. The Z-shaped plates at both ends are fixed to the connecting blocks 71 through the fixing holes, so that the loading plate component 30 is correspondingly fixed between the fixing assemblies 70 at both ends. The fixing assembly 70 can be connected to an external driving mechanism, and by driving the fixing assembly 70 to move, the loading plate component 30 can be correspondingly driven to move in the first direction, so as to facilitate the alignment of the first through hole 31 with the first upper pressure component 41 and the first lower pressure component 51.

[0068] Furthermore, a fixing block 72 is provided at the top of the connecting block 71. This fixing block 72 has a through-hole through which a connecting rod 73, movable along the axis of rotation, is inserted. Connecting rod 73 is connected to the connecting block 71. As connecting rod 73 moves within the through-hole, the connecting block 71 moves away from or closer to the fixing block 72. A first spring 74 is also provided around the connecting rod 73, located between the top of the connecting rod 73 and the fixing block 72. This first spring 74 is used to buffer downward pressure and support and reset the position of the loading plate assembly 30.

[0069] When not in use, the connecting block 71 remains in place, and the loading plate assembly 30, with both ends secured to the connecting block 71, remains in the first position A. When the loading plate assembly 30 is pressed downward from the first position A to the second position B, the connecting block 71 is moved away from the fixed block 72, the connecting rod 73 moves downward within the through-hole, and the first spring 74 is compressed. When the loading plate assembly 30 is no longer under downward pressure, the first spring 74 recovers its deformation, pushing the connecting rod 73 upward, driving the connecting block 71 closer to the fixed block 72, and correspondingly returning the loading plate assembly 30 from the second position B to the first position A.

[0070] By using the aforementioned fixing assembly 70, the requirements for positional fixation and movement of the loading plate member 30 in both the first direction and the rotation axis direction can be met simultaneously. Furthermore, the use of a removable fixing method to secure the loading plate member 30 facilitates disassembly and maintenance of the loading plate member 30, as well as replacement of the loading plate member 30 with through-holes of different sizes, further enhancing the applicability of the device.

[0071] The following describes the working process of the crimping device 100 provided in this embodiment. Similarly, the description will be made by taking the assembly 200 placed at the processing position corresponding to the first through hole 31 as an example.

[0072] First reference Figure 4 The first upper pressing member 41 includes a lower pressing end 411, an upper pressing end 412, and a pressing rod 413 connecting the lower pressing end 411 and the upper pressing end 412. A first mounting hole is formed on the first plate portion 21.

[0073] The pressure rod 413 is movably arranged in the first mounting hole, and the lower pressing end 411 is used to contact the external crimping drive rod 300. The upper pressure end 412 is located between the first plate portion 21 and the loading plate component 30, and a second spring (not shown in the figure) is also provided around the pressure rod 413. The second spring is located between the lower pressing end 411 and the first plate portion 21, and the second spring is used for buffering the downward pressure and for position support and resetting of the first upper pressure component 41. When the lower pressing end 411 is pressed downward to cause the pressure rod 413 to move downward, the second spring is compressed accordingly. When the lower pressing end 411 is no longer subjected to downward pressure, the compressed second spring recovers its deformation, causing the lower pressing end 411, the upper pressure end 412 and the pressure rod 413 to be reset to their initial state when they were not pressed downward.

[0074] The first lower pressure member 51 includes an abutting end 511, a lower pressure end 512, and a support rod 513 connecting the abutting end 511 and the lower pressure end 512. A second mounting hole is defined in the second plate portion 22. The support rod 513 is movably inserted into the second mounting hole. The abutting end 511 contacts the abutting surface 62, while the lower pressure end 512 is positioned between the second plate portion 22 and the mounting plate member 30.

[0075] The position of the force-bearing terminal component 60 is fixed. When the bracket component 20 moves in the first direction, the abutting end 511 gradually rises along the guide surface 63 until it abuts the abutting surface 62. The support rod 513 correspondingly moves, causing the lower pressure end 512 to be correspondingly raised to a position closer to the first through-hole 31. This facilitates the compression of the first side portion 2011 by the lower pressure teeth 510 when the mounting plate component 30 is pressed down to the second position B, thereby securing the first annular rib component 202 to the first side portion 2011.

[0076] refer to Figure 1 During the crimping process, first, the first upper pressure member 41 and the first lower pressure member 51 are aligned with the first through-hole 31 by driving the support member 20 and the loading plate member 30. At the same time, the first lower pressure member 51 is lifted and abutted by the force-bearing terminal member 60. Then, the assembly 200 is pushed out of the strip-shaped receiving groove 11 to the first table portion 131 by the pushing member 12, and the assembly 200 is clamped and pushed to the first through-hole 31 by the clamping member 14 through the second table portion 132. Figure 3 and Figure 4 At this time, the first annular rib component 202 of the assembly 200 is contacted and supported by the mounting surface 33 in the mounting plate component 30 , and the assembly 200 is limited in the limiting protrusion 34 .

[0077] refer to Figure 1 After the assembly 200 is loaded, the pressing drive rod 300 is driven by an external mechanism to press downward, contact the pressing end 411, and continue to press downward to move the pressing rod 413 downward, driving the upper pressing end 412 to move downward. Figure 4 The upper pressing end 412 contacts the second side portion 2012 of the assembly 200 downward and presses the mounting plate member 30 loaded with the assembly 200 from the first position A to the second position B. During the pressing process, both the first spring 74 and the second spring are compressed accordingly.

[0078] After the loading plate member 30 is pressed down to the second position B, the upper pressing teeth 410 of the upper pressing end 412 press against the periphery of the second side portion 2012, thereby deforming the metal to fix the second annular rib member 203 to the second side portion 2012. Simultaneously, through the reaction force of the abutment support, the lower pressing teeth 510 of the lower pressing end 512 press against the periphery of the first side portion 2011, thereby fixing the first annular rib member 202 to the first side portion 2011, thus completing the double-sided press connection.

[0079] After the crimping is completed, the crimping drive rod 300 is driven upward by an external mechanism, and the first spring 74 recovers its deformation, causing the loading plate member 30 to return from the second position B to the first position A. At the same time, the second spring recovers its deformation, returning the first upper pressure member 41 to its initial state when it is not pressed downward.

[0080] refer to Figure 1 After crimping is complete, the clamping member 14 grips the finished assembly 200 at the processing position and pushes the assembly 200 through the transition tables 131 and 132 to the conveyor belt 15. The conveyor belt 15 automatically collects and stores the processed assembly 200. The clamping member 14 then returns to the first table portion 131 to facilitate gripping and pushing the next assembly 200 to be processed back to the processing position.

[0081] In this embodiment, the conveyor belt 15 does not move unless it receives an assembly 200, ensuring that the assembly 200 can be stably held and pushed onto the conveyor belt 15. After the assembly 200 is pushed onto the conveyor belt 15, the conveyor belt 15 moves accordingly, pushing the assembly 200 a certain distance toward the storage box 16, and then stops. This leaves the positions of the conveyor belt 15 corresponding to the transition platforms 131 and 132 free to receive the subsequently pushed assembly 200. After all assemblies 200 in the strip-shaped receiving slots 11 have been processed, the conveyor belt 15 moves toward the storage box 16, transferring all assemblies 200 on the conveyor belt 15 to the storage box 16.

[0082] refer to Figure 3 In this embodiment, there are at least two upper pressure members, namely a first upper pressure member 41 and a second upper pressure member 42. There are at least two lower pressure members, namely a first lower pressure member 51 and a second lower pressure member 52. The two through holes are respectively a first through hole 31 and a second through hole 32.

[0083] The first through-hole 31 and the second through-hole 32 are arranged in a first direction in the mounting plate member 30. The first upper pressure member 41 and the second upper pressure member 42 are mounted on the first plate portion 21 in a first direction. The first lower pressure member 51 and the second lower pressure member 52 are mounted on the second plate portion 22 in a first direction. The first upper pressure member 41 and the first lower pressure member 51 are arranged opposite each other and mate with the first through-hole 31. The second upper pressure member 42 and the second lower pressure member 52 are arranged opposite each other and mate with the second through-hole 32.

[0084] The bracket member 20 is configured to be driven in a first direction so that one of the first lower pressing member 51 and the second lower pressing member 52 abuts against the force terminal member 60 .

[0085] The bracket component 20 and the loading plate component 30 are both configured to be driven in a first direction so that the first upper pressure component 41 and the first lower pressure component 51 are aligned with the first through hole 31 in the direction of the rotation axis, and / or the second upper pressure component 42 and the second lower pressure component 52 are aligned with the second through hole 32 in the direction of the rotation axis.

[0086] Specifically, when the assembly 200 to be processed of the first specification needs to be processed using the first upper pressure component 41 and the first lower pressure component 51, the bracket component 20 is driven to make the end of the first lower pressure component 51 abut against the force-bearing terminal component 60, and the carrier plate component 30 is driven to move the first through hole 31 between the first upper pressure component 41 and the first lower pressure component 51. At this time, after the assembly 200 to be processed is placed at the position of the first through hole 31 of the carrier plate component 30, the assembly 200 can be crimped and connected using the first upper pressure component 41 and the first lower pressure component 51. Since both the bracket component 20 and the carrier plate component 30 can be driven, in the processing state, the first upper pressure component 41 and the first lower pressure component 51 on the bracket component 20 can be aligned with the first through hole 31 on the carrier plate component 30 to improve processing accuracy. In a non-processing state, the support member 20 and the placement plate member 30 can be staggered to facilitate the removal and replacement of the first upper pressure member 41 and the first lower pressure member 51 .

[0087] Similarly, when the second specification assembly 200 to be processed needs to be processed using the second upper pressure component 42 and the second lower pressure component 52, the bracket component 20 is driven to make the end of the second lower pressure component 52 abut against the force-bearing terminal component 60, and the mounting plate component 30 is driven to move the second through hole 32 between the second upper pressure component 42 and the second lower pressure component 52. At this time, after the assembly 200 to be processed is placed at the position of the second through hole 32 of the mounting plate component 30, the second upper pressure component 42 and the second lower pressure component 52 can be used to press and connect the assembly 200.

[0088] As described above, according to the crimping device 100 provided in this embodiment, a pressure component that matches the specifications of the assembly 200 to be processed can be selected from multiple pressure components to improve the processing efficiency when crimping assemblies 200 of various specifications.

[0089] In addition, in this embodiment, since the arrangement direction of the multiple through holes (the first through hole 31 and the second through hole 32) and the arrangement direction of the multiple pressure components (the first upper pressure component 41 and the second upper pressure component 42, the first lower pressure component 51 and the second lower pressure component 52) ​​are in the same direction, it is beneficial to simplify the movement trajectory of the bracket component 20 and the loading plate component 30, that is, the bracket component 20 and the loading plate component 30 can complete the alignment of the through holes and the pressure components through simple linear motion, thereby improving production efficiency and production applicability.

[0090] In this embodiment, the specific structure and press-fitting process of the second through hole 32, the second upper pressure component 42 and the second lower pressure component 52 are the same as the specific structure and press-fitting process of the first through hole 31, the first upper pressure component 41 and the first lower pressure component 51 described above.

[0091] In this embodiment, the movements of the pushing member 12 , the clamping member 14 , the placing plate component 30 , the bracket component 20 and the pressing driving rod 300 are all precisely controlled by the servo motor.

[0092] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
