Description

Technical Field

[0001] The invention relates to the field of riveting mechanical equipment, in particular to a rotary riveting equipment. Background Art

[0002] In the prior art, riveting is mostly used to connect thin metal plates. For example, a rotary riveting device is a tool for realizing riveting operations. Its structure can refer to the "A rotary riveting device" disclosed in the Chinese utility model patent with patent number CN202420129748.0 (publication number CN221817274U). When the rotary riveting device is in use, the workpiece to be processed is placed on the workbench, and the driving motor drives the working rod to operate the workpiece. Since the rivet needs to be 0.5-1.0mm higher than the connection surface, if the rivet is too long above the connection surface, the rivet head will be too large and the nail rod will be easy to bend; if the rivet is too short above the connection surface, the pier thickness is insufficient, the nail head is not fully formed, and the riveting strength and tightness are affected. For this reason, the rotary riveting device uses multiple clamping plates to clamp the workpiece stably to prevent the unstable movement of the workpiece during the riveting process, thereby ensuring the depth and strength of each riveting point.

[0003] However, this riveting equipment is only for workpieces with only one side of the working surface. However, if the workpiece to be operated is Figure 1-2 The shell shown in the figure will cause another assembly problem. The shell has more than one working surface to be operated, that is, it includes a first side wall 1' and a second side wall 2' that are not on the same working surface, and a first gasket 3' needs to be riveted on the first side wall 1', and a second gasket 4' needs to be riveted on the second side wall 2', wherein the edge of the first side wall 1' has a concave step 11', and the step 11' has a first wall surface 111' parallel to the first side wall 1', and a second wall surface 112' connecting the first wall surface 111' and the first side wall 1', the first wall surface 111' is relatively narrow, and the first gasket 3' is riveted on the first wall surface 111', and the first gasket 3' is a long thin sheet , and a plurality of riveting points for rivets to pass through are arranged at intervals along the length. If one of the riveting points is not accurately positioned, it will cause the other riveting points to be inaccurately positioned, so that it is easy to move during the riveting process, and it is difficult to ensure the depth and strength of each riveting point; and it is easy to warp and deform during the riveting process. If the first gasket 3' is warped and deformed, the rivet connecting the first gasket 3' and the first side wall 1' will not be high enough above the first gasket 3', resulting in a loose connection between the first gasket 3' and the first side wall 1'. Even if the downward pressure of the rotary rivet head is increased to press the first gasket 3' against the first side wall 1', the deformation degree of the first gasket 3' will be aggravated, and the yield rate of product processing will be reduced.

[0004] The second gasket 4' is a thin sheet with a large hollow area in the center. The riveting points are set on the periphery of the hollow area. It will also move due to inaccurate positioning. In addition, due to the large hollow area in the center, it is easy to bend and deform during the riveting process. If the above-mentioned rotary riveting equipment is used to process the workpiece to be processed, the following problems will occur: First, when the first gasket 3' is riveted to the first side edge 1', due to the long and thin characteristics of the first gasket 3', it is easy to be inaccurately positioned or warp and deform during the processing. Second, because the first gasket 3' needs to be riveted to the first wall 111', and the first wall 111' is relatively narrow, it is impossible to clamp the workpiece from both ends with the existing clamping plate. At the same time, the second wall 112' will also cause the clamping plate to Interference occurs; thirdly, when the second gasket 4' is riveted to the second side 2', since the workpiece placement direction is different from that when processing the first side 1', different positioning fixtures need to be replaced accordingly to meet the processing requirements of different sides 2'. If the positioning fixture is repeatedly replaced during each processing, a lot of time and energy will be consumed, reducing the processing efficiency. At the same time, the second gasket 4' is prone to arching and deformation in the center, which can easily cause inadequate riveting or aggravate the deformation of the second gasket 4' and reduce the yield rate. Summary of the invention

[0005] The first technical problem to be solved by the present invention is to provide a rotary riveting device that can avoid gasket deformation during processing and ensure the tightness of rivet connection in response to the above-mentioned existing technical status, which is particularly suitable for long and thin gaskets and narrow working surfaces.

[0006] The second technical problem to be solved by the present invention is to provide a workpiece riveting device capable of reducing the workload of operators in view of the above-mentioned existing technical status, and is particularly suitable for workpieces to be operated on which the working surfaces are more than one.

[0007] The technical solution adopted by the present invention to solve the above-mentioned first technical problem is: the rotary riveting equipment comprises

[0008] Workbench;

[0009] A riveting head is arranged on the workbench;

[0010] The first station, located on the workbench, is used to rivet the first gasket to the first side wall of the workpiece to be worked on.

[0011] The edge of the first side wall has a concave step, the step has a first wall surface parallel to the first side wall, and a second wall surface connecting the first wall surface and the first side wall, the first wall surface is relatively narrow and has a plurality of rivets, the first gasket is a long thin sheet, and the first gasket has a rivet hole corresponding to each rivet, characterized in that the first station is provided with:

[0012] The first auxiliary mechanism can act on the interval section between two adjacent rivet holes in the first gasket from top to bottom, so that each rivet hole of the first gasket is aligned one by one with the rivets preset on the first wall surface, thereby achieving: while avoiding the first gasket from warping and deformation, the height H of each rivet above the first gasket always satisfies: 0.5mm≤H≤1mm.

[0013] Since the working surface of the first gasket is the first wall, that is, it is arranged in the step with the concave edge in the shell, and due to its narrow limitation, the first auxiliary mechanism can only be designed to be independent of the first wall and press downward from top to bottom along the direction of the step. Further, the first auxiliary mechanism includes:

[0014] A main body, arranged on the workbench;

[0015] A pressing member, used to press or abut the interval section corresponding to the first gasket, includes at least two pressing members arranged on the top wall of the body, each pressing member includes a head portion for pressing the interval section of the first gasket, and a tail portion of each pressing member is connected to the power output end of the body through a connecting structure arranged in the body;

[0016] A hinged portion, also disposed on the top wall of the body, located between the head portion and the tail portion and capable of being hinged to the body;

[0017] An adjusting member, arranged on the head of each of the pressing members, for adjusting the pre-pressure of the head acting on the interval between the first gaskets;

[0018] When the power output end of the power unit in the main body drives the connecting structure to move upward along the center line of the main body, each connecting rod of the connecting structure drives the corresponding head of the clamping member to rotate around the hinge part, and under the joint action of the power unit and the adjusting component in the main body, the head of each clamping member selectively presses or abuts against the interval section of the first gasket.

[0019] In this way, the heads of the corresponding clamping members are driven to rotate around the hinged parts through the connecting rods of the connecting structure, so that the clamping members can act on the interval segments of the first gasket from top to bottom, which is suitable for situations where the working surface is relatively narrow. In addition, since the first auxiliary mechanism as a whole is independently arranged outside the first wall surface, it is different from the existing "clamping mechanism" that directly acts on the first wall surface. Therefore, when it acts on the first gasket, only the head of the clamping member acts on the interval segments of the first gasket with the help of the adjusting mechanism to exert pre-pressure, thereby applying appropriate pre-pressure to each interval segment, pressing or resisting the first gasket in a point contact manner, and avoiding deformation of the first gasket caused by the pre-pressure applied by the clamping member.

[0020] Furthermore, the tail of each of the clamping members is connected to the connection structure by means of a connection portion extending along the length direction of the first gasket, and the head of each of the clamping members extends in a horizontal direction perpendicular to the center line of the body, wherein a protrusion with a "J"-shaped cross section is provided on every one or more interval segments in the first gasket, and each protrusion maintains a preset height with the first wall surface, and the corresponding clamping member controls the protrusion to only abut against the interval segment to control its warping deformation by means of its corresponding adjustment member. Due to the special design of the protrusion in the first gasket, if the clamping member is pressed on the interval segment with a protrusion, the protrusion will bend downward due to pressure, and the two sides of the protrusion will warp and deform. Therefore, the adjustment member is the key design of the first auxiliary mechanism, and it needs to be adaptively adjusted to the protrusion so that it only abuts against the protrusion without applying additional force to the protrusion.

[0021] Furthermore, the head of each of the clamping members is a finger-like structure extending in a horizontal direction perpendicular to the center line of the main body. The adjusting member protrudes from the head of each of the clamping members in the direction of the first wall surface and is constrained at the periphery of the adjusting hole in the head of each of the clamping members, with its extension direction being parallel to the second wall surface, thereby enabling the adjusting member to press or abut against the first gasket in a point contact manner when moving up and down along the adjusting hole.

[0022] The applicant needs to emphasize that: due to the narrowness of the first wall, there is a lack of space near the first wall for the adjustment method similar to the existing "clamping mechanism" that directly acts on the first wall to move left and right or forward and backward. Therefore, while designing the clamping piece into a finger-like structure, the adjustment method of the adjustment member is also designed to protrude along the head of each clamping piece toward the direction of the first wall. These two designs can achieve the technical effect of 1+1>2. First, the clamping piece can be used to press or hold the first wall from top to bottom in a point contact manner like a finger with the help of the adjustment member. Against the first gasket, secondly: the adjusting component can move up and down in the adjusting hole to adjust the pressing member for the protrusion to only press against the protrusion, while other pressing members can appropriately increase the pre-tightening force to press the interval segment, so that it can be adaptively adjusted according to the design characteristics of the first gasket; in addition, the adjusting component adjusts the pre-pressure acting on the interval segment in an "up and down movement" manner, avoiding the problem of occupying a large adjustment space by "moving left and right" or "moving front and back" in the existing scheme, thereby being well suitable for the first wall surface with narrow limitations.

[0023] In order to enable the adjusting member to adjust the pre-pressure of the head acting on the interval between the first gaskets, preferably, the adjusting member comprises:

[0024] An adjusting screw, the extension direction of which is parallel to the second wall surface, the lower end of which passes through the adjusting hole and can act on the spacing section of the first gasket, the upper end of which is exposed above the screw hole for adjustment, and the adjusting screw has an external thread;

[0025] A nut, fixed on the adjusting hole, having an internal thread matching the external thread of the adjusting screw;

[0026] When the adjusting screw rotates relative to the nut, the adjusting screw can move up and down, thereby adjusting the pre-pressure of the head on the interval section of the first gasket, so that the head selectively presses or abuts against the interval section of the first gasket. When in use, the adjusting screw or the adjusting nut is rotated to move the adjusting screw downward relative to the pressing member, so that the pre-pressure of the head on the interval section of the first gasket can be increased, so that the head presses against the interval section of the first gasket; and when the adjusting screw moves upward relative to the pressing member, the pre-pressure on the interval section of the first gasket can be reduced. When the adjusting screw just abuts against the interval section of the first gasket, the adjusting screw contacts the interval section of the first gasket without applying any force.

[0027] To solve the second technical problem mentioned above, preferably, the riveting equipment further includes a second station for riveting the second gasket to the second side wall of the workpiece to be processed, wherein the second side wall and the first side wall are on different working surfaces of the workpiece to be processed, the second gasket is a thin sheet with a large hollow area in the center, the second station is arranged adjacent to the first station, and a second auxiliary mechanism is arranged on the second station, the second auxiliary mechanism is the same as the first auxiliary mechanism, and only one pressing member is arranged, and the pressing member corresponds to pressing the center of the second gasket. The second auxiliary mechanism can press the central hollow part of the second gasket to prevent the second gasket from arching and deforming due to the large hollow area in the center.

[0028] Furthermore, it also includes:

[0029] The loading and unloading area includes a first loading and unloading position for loading or unloading the workpiece to be processed to the first station, and a second loading and unloading position for loading or unloading the workpiece to be processed to the second station;

[0030] A rotary riveting area, including a first rotary riveting position corresponding to a first station for riveting a first gasket to a first wall surface, and a second rotary riveting position corresponding to a second station for riveting a second gasket to a second side wall, wherein the rotary riveting head is located above the rotary riveting area;

[0031] A first conveying member is arranged along the Y-axis direction of the workbench, and is used to drive the first station to move along the Y-axis direction and convey the first station from the first loading and unloading position to the first riveting position. The riveting head can perform riveting operation on the first station when the first station is located at the first riveting position. The first conveying member is also used to convey the first station from the first riveting position back to the first loading and unloading position.

[0032] A second conveying member is arranged in parallel with the first conveying member, and is used to drive the second station to move along the Y-axis direction and convey the second station from the second loading and unloading position to the second riveting position. The riveting head can perform riveting operation on the second station when the second station is located at the second riveting position. The second conveying member is also used to convey the second station from the second riveting position back to the second loading and unloading position. The rotation paths of the first conveying member and the second conveying member are arranged oppositely with respect to the operation sequence of the riveting head.

[0033] The third conveying member is arranged along the X-axis direction of the workbench, and is used for driving the spin riveting head to move along the X-axis direction and conveying the spin riveting head to the first spin riveting position when the first station is located at the first spin riveting position, and conveying the spin riveting head to the second spin riveting position when the second station is located at the second spin riveting position. The rotation paths of the first conveying member and the second conveying member are set oppositely to the operating sequence of the rivet head. When the rivet head is located at the first rivet position at the first station, the rivet operation can be performed on the first station. The operator can load another workpiece to the second station during the rivet operation and operate the second auxiliary mechanism to press the second gasket. When the rivet operation is completed at the first station, the first station is transferred from the first rivet position back to the first loading and unloading position, and the second station is transferred from the second loading and unloading position to the second rivet position, and the rivet head is transferred from above the first rivet position to above the second rivet position to perform the rivet operation at the second station. At this time, the operator can unload the workpiece that has completed the operation at the first station and load the new workpiece to be operated, and repeat this process, so that the rivet equipment can work non-stop and improve work efficiency.

[0034] Furthermore, the first auxiliary mechanism and the second auxiliary mechanism are both connected to their respective corresponding receiving seats, and move along a preset track driven by their respective corresponding conveying components.

[0035] In order to improve production safety, preferably, a partition is provided between the first loading and unloading position and the second loading and unloading position to separate the first loading and unloading position and the second loading and unloading position. The provision of the partition can separate the first loading and unloading position and the second loading and unloading position so that they are separated in space, thereby avoiding mutual interference between the first loading and unloading position and the second loading and unloading position, and improving the safety of the operation of the operator.

[0036] Compared with the prior art, the advantages of the present invention are: the first auxiliary mechanism is arranged at the first workstation of the rotary riveting equipment, and the first auxiliary mechanism can act on the interval section between two adjacent rivet holes in the first gasket from top to bottom, so that it is suitable for the situation where the working surface is relatively narrow. Under the action of the first auxiliary mechanism, each rivet hole of the first gasket is aligned one by one with the rivet preset on the first wall surface, while avoiding the warping and deformation of the first gasket, each rivet section is fully exposed and the height H higher than the first gasket is always 0.5-1.0mm, so as to ensure the tightness of the rivet connection. At the same time, since each rivet hole is aligned one by one with the rivet preset on the first wall surface, the deformation and movement of the first gasket are avoided, the possibility of burrs generated by the friction between the rotary rivet head and the edge of the rivet hole during the rotary riveting process is reduced, and the yield rate of the workpiece to be operated is improved.

[0049] The present invention is further described in detail below with reference to the accompanying drawings.

[0050] like Figure 3-12 As shown, the present rotary riveting device is the best embodiment of the present invention. The rotary riveting device of this embodiment is a tool widely used for implementing riveting operations. When the workpiece B to be operated is a shell provided in the background technology, such as Figure 4 As shown, it has more than one working surface to be operated, namely, including a first side wall B1 and a second side wall B4 which are not on the same working surface, wherein the edge of the first side wall B1 has a concave step B2, the step B2 has a first wall surface B21 parallel to the first side wall B1, and a second wall surface B22 connecting the first wall surface B21 and the first side wall B1, a first gasket A needs to be riveted on the first wall surface B21, and a second gasket C needs to be riveted on the second side wall B4, and a first station 3 for riveting the first gasket A to the first wall surface B21 and a second station 5 for riveting the second gasket C to the second side wall B4 are provided on the workbench 1 of the rotary riveting equipment.

[0051] In addition to the above-mentioned particularities of the working surface, the first gasket A is a long thin sheet and is provided with a rivet hole A1 corresponding to each rivet B3 preset on the first wall surface B21. Figure 4 As shown, there is a spacing section A2 between two adjacent rivet holes A1, and each spacing section A2 is provided with a protrusion A3 with a "J"-shaped cross section, and three protrusions A3 are provided along the length direction of the first gasket A, and each protrusion A3 maintains a preset height with the first wall surface B21. The second gasket C is different from the first gasket A. The second gasket C is a thin sheet with a large hollow area in the center. Due to the large hollow area in the center, the center of the second gasket C is prone to arching and deformation.

[0052] To this end, the rotary riveting equipment of this embodiment is specifically improved for a specific working surface and a specific gasket structure. The structure of the first station 3 corresponding to the first side wall B1 of the first gasket A is first described. Figure 5-6In order to align the rivet holes A1 of the first gasket A with the rivets B3 preset on the first wall surface B21 one by one, a first auxiliary mechanism 4 is designed on the first station 3. According to the special design of the first gasket A, the first auxiliary mechanism 4 can act on the interval section A2 of the first gasket A from top to bottom. The first auxiliary mechanism of this embodiment includes a body 41, a pressing member 42 and a hinge 43. The main body 41 is arranged on the workbench 1, and the tail 42b of each clamping member 42 is connected to the connecting structure 411 arranged in the main body 41 by means of a connecting portion 45 extending along the length direction of the first gasket A, and is connected to the power output end of the main body 41 through the connecting structure 411, and the hinge part 43 is arranged on the top wall of the main body 41, located between the head 42a and the tail 42b and can be hinged on the main body 41. When the power output end of the power part in the main body 41 drives the connecting structure 411 to move upward along the center line of the main body 41, each connecting rod of the connecting structure 411 drives the head 42a of the corresponding clamping member 42 to rotate around the hinge part 43, and under the joint action of the power part and the adjusting member 44 in the main body 41, the head 42a of each clamping member 42 selectively presses or abuts against the interval segment A2 of the first gasket A. The first auxiliary mechanism 4 drives the head 42a of the corresponding pressing member 42 to rotate around the hinge 43 through each connecting rod of the connecting structure 411, so that the pressing member 42 can act on the interval A2 of the first gasket A from top to bottom. The first auxiliary mechanism 4 is independently arranged outside the first wall surface B21 as a whole, which is different from the existing "clamping mechanism" that directly acts on the first wall surface B21. Therefore, when it acts on the first gasket A, only the head 42a of the pressing member 42 acts on the interval A2 of the first gasket A with the help of the adjustment mechanism. The pre-pressure is applied to each interval A2, and the first gasket A is pressed or pressed in a point contact manner to avoid deformation of the first gasket A caused by the pre-pressure applied by the clamping member.

[0053] However, if the head 42a of the clamping member 42 acts directly on the raised portion A3, the raised portion A3 will bend downward due to the pressure, and the two sides of the raised portion A3 will be tilted and deformed. The first auxiliary mechanism 4 can selectively press or press against the interval segment A2 with the help of the adjusting member 44, thereby achieving: while preventing the first gasket A from tilting and deforming, the height H of each rivet B3 above the first gasket A always satisfies: 0.5mm≤H≤1mm. Since the first wall surface B21 is set in the step B2 recessed at the edge of the first side wall B1, it has the limitation of being narrow and thin, and the first auxiliary mechanism 4 can only be designed to be independent of the first wall surface B21 and press from top to bottom along the direction of the step B2. Specifically, refer to Figure 7The clamping component of the first auxiliary mechanism 4 includes at least two clamping members 42 arranged on the top wall of the main body 41 and designed to be a finger-like structure. The head 42a of each clamping member 42 is a finger-like structure extending in a horizontal direction perpendicular to the center line of the main body 41. The adjusting member 44 protrudes from the head 42a of each clamping member 42 in the direction of the first wall surface B21 and is constrained by the periphery of the adjusting hole 421 in the head 42a of each clamping member 42. Its extension direction is parallel to the second wall surface B22. The finger-like clamping member 42 and the clamping member 42 protrude from the head 42a of each clamping member 42 in the direction of the first wall surface B21. The adjusting member 44 enables the clamping member 42 to press or abut against the first gasket A from top to bottom in a point contact manner like a finger with the help of the adjusting member 44. Whether the pressing piece 42 presses or presses against the spacing segment A2 depends on the shape of the spacing segment A2 of the first gasket A to which the pressing piece 42 corresponds. If the pressing piece 42 presses on the spacing segment A2 with a protrusion A3, the protrusion A3 will bend downward due to the pressure, while the two sides of the protrusion A3 will warp and deform. Therefore, the pressing piece 42 acting on the protrusion A3 controls the pressing piece 42 to only press against the protrusion A3 with the help of its corresponding adjusting component 44 without applying additional force to the protrusion A3 to control its warping and deformation.

[0054] In addition to designing the clamping piece 42 as a finger-like structure, the focus is also on designing the adjustment method of the adjustment member 44 to protrude along the head 42a of each clamping piece 42 in the direction of the first wall B21. These two designs can achieve the technical effect of 1+1>2. First, the clamping piece 42 can be pressed or pressed against the first gasket A from top to bottom in a point contact manner like a finger with the help of the adjustment member 44. Second, the adjustment member 44 can move up and down in the adjustment hole 421 to adjust the clamping piece 42 for the protrusion A3 to only press against the protrusion A3, while other clamping pieces 42 can appropriately increase the pre-tightening force to press the interval segment A2, so that it can be adaptively adjusted according to the design characteristics of the first gasket A. Also, due to the narrowness of the first wall B21, it is difficult to reserve the adjustment space required for the "clamping mechanism" to move forward and backward or left and right for adjustment on the first wall B21. The adjustment member 44 can only adjust the preload of the head 42a on the interval A2 between the first gaskets A by moving up and down. Figure 7The adjusting member 44 includes an adjusting screw 441 and a nut 442. The extension direction of the length of the adjusting screw 441 is parallel to the second wall surface B22. The lower end of the adjusting screw 441 passes through the adjusting hole 421 and can act on the interval segment A2 of the first gasket A. The upper end of the adjusting screw 441 is exposed above the screw hole for adjustment. The adjusting screw 441 has an external thread, and the nut 442 is fixed on the adjusting hole 421 and has an internal thread that matches the external thread of the adjusting screw 441. When the adjusting screw 441 rotates relative to the nut 442, the adjusting screw 441 can move up and down, thereby adjusting the pre-pressure of the head 42a acting on the interval segment A2 of the first gasket A, so that the head 42a selectively presses or abuts against the interval segment A2 of the first gasket A. The adjusting member 44 adjusts the pre-pressure acting on the interval segment A2 by "moving up and down", avoiding the problem of occupying a large adjustment space by "moving left and right" or "moving front and back" in the existing solution, and is thus well suited for the first wall B21 with narrow limitations.

[0055] like Figure 8-9 As shown, the structure of the second station 5 corresponding to the operation of riveting the second side wall B4 of the second gasket C is described. In order to align the various rivet holes A1 of the second gasket C with the rivets B3 preset on the second side wall B4, a second auxiliary mechanism 6 is correspondingly designed on the second station 5. The second auxiliary mechanism 6 is basically the same as the first auxiliary mechanism 4, and the special design for the second gasket C has the following changes: only one pressing member 42 is provided, and the pressing member 42 corresponds to pressing the center of the second gasket C. The pressing member 42 and the second gasket C are in surface contact, and a protective pad 61 is provided on the contact surface, so that the pressing member 42 and the second gasket C are in soft contact. The setting of the second auxiliary mechanism 6 can press the central hollow part of the second gasket C to prevent the second gasket C from arching and deforming due to the large hollow area in the center.

[0056] In addition, in order to enable the operator to work between the first station 3 and the second station 5 without stopping in time sequence, the two working surfaces of the product are processed. Figure 10-12As shown, the rotary riveting equipment of this embodiment also includes a loading and unloading area 7 and a rotary riveting area 8. The loading and unloading area 7 includes a first loading and unloading position 71 for loading or unloading the workpiece B to be operated to the first station 3, and a second loading and unloading position 72 for loading or unloading the workpiece to be operated to the second station 5. A partition 10 is arranged between the first loading and unloading position 71 and the second loading and unloading position 72 to separate the first loading and unloading position 71 and the second loading and unloading position 72. The arrangement of the partition 10 can separate the first loading and unloading position 71 and the second loading and unloading position 72, so that they are separated in space, thereby avoiding mutual interference between the first loading and unloading position 71 and the second loading and unloading position 72 and improving the safety of the operation of the operators. The riveting area 8 includes a first riveting position 81 corresponding to the first station 3 for riveting the first gasket A to the first wall surface B21, and a second riveting position 82 corresponding to the second station 5 for riveting the second gasket C to the second side wall B4. A riveting head 2 is provided on the riveting area 8. The riveting head 2 is transferred between the first riveting position 81 and the second riveting position 82 by means of a third conveying member 93. The third conveying member 93 is arranged along the X-axis direction of the workbench 1, and transfers the riveting head 2 to the first riveting position 81 when the first station 3 is located at the first riveting position 81, and transfers the riveting head 2 to the second riveting position 82 when the second station 5 is located at the second riveting position 82.
