[0002] Currently, riveting equipment is often used in the assembly of some electromechanical and light industrial products such as automobiles, instruments, and decorations. Most riveting equipment uses its own rivet gun to cause plastic deformation of the riveted parts, thereby completing the riveting operation.

[0003] However, existing riveting equipment, when used for riveting a single workpiece, typically requires manual positioning of the workpiece on the riveting platform. Simultaneously, the operator must manually control the riveting gun to perform multiple riveting operations. Thus, the entire riveting process is quite cumbersome for a single operator.

[0023] The following description is intended to disclose this application and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of this application defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of this application.

[0024] Those skilled in the art should understand that, in the disclosure of this application, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this application.

[0025] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0026] refer to Figures 1 to 4 A preferred embodiment of the riveting device according to this application will be described in detail below. The riveting device is used to perform a riveting operation on at least one workpiece 90. The riveting device includes a device body 10, a positioning component 20 and at least one riveting device 30.

[0027] Specifically, the positioning component 20 includes a support plate 21 and at least one pressing member 22. The support plate 21 is mounted on the device body 10, and at least one first space 2101 is uniformly formed on the top of the support plate 21. The support plate 21 also symmetrically provides a set of limiting protrusions 211 on opposite sides of each first space 2101. Each set of limiting protrusions 211 includes multiple limiting protrusions 211. Each set of limiting protrusions 211 forms a second space 2102 around the top of the support plate 21. The two symmetrical second spaces 2102 combined with one first space 2101 form a limiting space for placing a workpiece 90.

[0028] It should be noted that each of the workpieces 90 has a flange edge 91 at the bottom of its two opposite sides. The size of each flange edge 91 is adapted to the size of one of the second spaces 2102. Thus, when a workpiece 90 is placed on top of the support plate 21, since the size of the two flange edges 91 of each workpiece 90 is adapted to the size of the two corresponding second spaces 2102, the two flange edges 91 of the workpiece 90 are respectively limited by two sets of limiting protrusions 211, thereby limiting each workpiece 90 placed on the support plate 21 in the horizontal direction.

[0029] Preferably, each of the limiting protrusions 211 in each group is provided with its top integrally inclined toward the outside of the corresponding second space 2102 to form an inclined surface 2111. The inclined surface 2111 of each limiting protrusion 211 is at least partially oriented toward the corresponding second space 2102, so that when placing the workpiece 90, the workpiece 90 can be easily placed in the limiting space by the guiding effect of the inclined surface 2111 of each limiting protrusion 211.

[0030] Each of the pressing members 22 includes a driving element 221 and a pressing arm 222, wherein each driving element 221 is connected to the top of the support plate 21 and is close to at least one of the first spaces 2101. One pressing arm 222 is driven to be movably connected to one of the driving elements 221, and at least one end of each pressing arm 222 is provided with a pressing portion 2221 close to the support plate 21, and at least one pressing portion 2221 is provided above one of the first spaces 2101, so that when one of the driving elements 221 drives one pressing arm 222 to move, at least one pressing portion 2221 of one pressing arm 222 is configured to be relatively movable towards and away from the support plate 21.

[0031] Understandably, when a workpiece 90 is placed on top of the support plate 21, the drive element 221 is activated to bring a corresponding pressing arm 222 closer to the support plate 21, so that at least one pressing part 2221 of each pressing arm 222 is synchronously driven to gradually approach the support plate 21 until each pressing part 2221 of each pressing arm 222 presses against the workpiece 90. At this time, the workpiece 90 placed on the support plate 21 is limited in the vertical direction.

[0032] Thus, each workpiece 90 placed on the support plate 21 is limited in the horizontal direction by the two sets of limiting protrusions 211 of the support plate 21, and is limited in the vertical direction by the pressing member 22, thereby enabling each workpiece 90 to be stably positioned on the support plate 21, eliminating the need for manual positioning.

[0033] It is worth mentioning that the riveting device 30 is used to perform a riveting operation on at least one of the workpieces 90 positioned by the positioning component 20. Therefore, each of the pressing portions 2221 is held above the position where the support plate 21 forms the first space 2101, while also being offset from the riveting area of ​​each workpiece 90. In this way, when the pressing arm 222 presses against the workpiece 90 through the pressing portions 2221, the pressing portions 2221 pressing against the workpiece 90 are unlikely to obstruct the riveting operation of the riveting device 30.

[0034] Preferably, each of the drive elements 221 is implemented to include a telescopic device, such as a telescopic cylinder.

[0035] Preferably, specifically as follows Figure 3 As shown, at least one of the pressing arms 222 is disposed between two adjacent limiting spaces, and each of the pressing arms 222 disposed between the two adjacent limiting spaces has a pressing part 2221 at both ends, and the two pressing parts 2221 are respectively held above the two adjacent limiting spaces. Thus, when a driving element 221 drives the pressing arm 222 with the two pressing parts 2221 to move to press against the workpiece 90, the pressing arm 222 with the two pressing parts 2221 presses against the workpiece 90 in the two adjacent limiting spaces through the two pressing parts 2221 respectively.

[0036] Preferably, at least one of the pressing portions 2221 of each pressing arm 222 is integrally extended toward both sides of the support plate 21 until each pressing portion 2221 spans over a corresponding limiting space. This increases the contact area between the pressing portion 2221 and a workpiece 90 placed in the limiting space, thereby enabling a workpiece 90 to be stably pressed against the corresponding limiting space.

[0037] In a preferred embodiment, specifically as follows: Figure 3As shown, the support plate 21 forms two limiting spaces evenly and at intervals on its top, and the number of the pressing members 22 is set to three. One pressing member 22 is disposed between the two limiting spaces, and the pressing arm 222 of the pressing member 22 disposed between the two limiting spaces is provided with a pressing part 2221 at both ends. The other two pressing members 22 are respectively disposed on one side of the two limiting spaces, and are respectively opposite to the pressing member 22 disposed between the two limiting spaces.

[0038] Further, the positioning component 20 also includes a connecting member 23. In one embodiment, the connecting member 23 includes a pair of support platforms 231, a driving member 232, and a pair of connecting blocks 233. The two support platforms 231 are disposed opposite to each other and spaced apart on the same side of the device body 10. The two connecting blocks 233 are disposed opposite to each other and spaced apart between the two support platforms 231. One of the connecting blocks 233 is rotatably connected to one of the support platforms 231, and the other connecting block 233 is synchronously rotatably connected to the driving member 232. The driving member 232 is connected to one of the support platforms 231. The two ends of the bearing plate 21 are respectively connected to the two connecting blocks 233.

[0039] It is understood that the support plate 21 is disposed on the equipment body 10 by the connecting member 23 so as to position the workpiece 90.

[0040] Furthermore, since each workpiece 90 positioned on the support plate 21 does not only have one side requiring riveting, and the riveting areas on different sides of each workpiece 90 are not easily accessible for direct riveting by the riveting device 30, the drive unit 232 is activated to rotate the support plate 21. This causes each workpiece 90 positioned on the support plate 21 to rotate synchronously with the support plate 21, adjusting the different sides of each workpiece 90. This facilitates the riveting device 30 in directly riveting the adjusted riveting areas on each workpiece 90.

[0041] Preferably, the driving member 232 is implemented as a driving motor, and both of the connecting blocks 233 are implemented as a connecting plate with a rotating shaft, that is, one of the connecting blocks 233 is driven by the driving member 232 to rotate the workpiece 90 positioned on the support plate 21.

[0042] In another embodiment, the connecting member 23 includes a pair of support platforms 231, a pair of driving members 232, and a pair of connecting blocks 233, wherein the two support platforms 231 are disposed opposite to and spaced apart on the same side of the device body 10. The two driving members 232 are respectively connected to the tops of the two support platforms 231 and are located at the same horizontal height. The two connecting blocks 233 are respectively rotatably connected to the two driving members 232. The two ends of the bearing plate 21 are respectively connected to the two connecting blocks 233.

[0043] It is understandable that when the positioned workpiece 90 needs to be flipped, the two driving components 232 are activated to drive the corresponding two connecting blocks 233 to rotate synchronously, so that the support plate 21 is driven to rotate synchronously. In this process, the driving force of the two driving components 232 driving the support plate 21 to rotate is smaller than the driving force of a single driving component 232 driving the support plate 21 to rotate. As a result, the reaction force when the two driving components 232 drive the support plate 21 to rotate is also smaller. That is, each driving component 232 is unlikely to fail in a short period of time.

[0044] It is worth mentioning that the support plate 21 also forms at least one notch 2103. Preferably, one of the notches 2103 is set to simultaneously penetrate the bottom and top of the support plate 21 and communicate with a first space 2101. In this way, when the riveting area of ​​a workpiece 90 placed in the limiting space faces the support plate 21, the support plate 21 can be flipped by the connecting member 23 so that the notch 2103 of the support plate 21 faces the riveting device 30. At this time, the workpiece 90 located in the limiting space exposes the riveting area through the notch 2103 and faces the riveting device 30, so that the riveting device 30 can perform riveting operation on the riveting area of ​​the workpiece 90 through the notch 2103.

[0045] Preferably, the driving element 232 is implemented as a driving motor, and the two connecting blocks 233 are both implemented as connecting plates with rotating shafts, that is, the two connecting blocks 233 are driven by the two driving elements 232 respectively to synchronously drive the workpiece 90 positioned on the support plate 21 to rotate.

[0046] Furthermore, the positioning component 20 also includes two sets of pads 24. Preferably, each set of pads 24 includes at least two pads 24, and at least two pads 24 in each set are evenly arranged and flush with each other in one of the first spaces 2101 of the support plate 21. Each pad 24 in the set is detachably connected to the top of the support plate 21 to support the workpiece 90. In addition, the vertical height of each pad 24 in the set is lower than the vertical height of each limiting protrusion 211.

[0047] It is understood that when a workpiece 90 is placed in the limiting space on top of the support plate 21, since a set of pads 24 are provided in one of the first spaces 2101, there is a gap between the workpiece 90 placed in the limiting space and the top of the support plate 21. Thus, when it is necessary to remove a workpiece 90 from one of the limiting spaces, the operator can directly reach in through the gap between the workpiece 90 and the top of the support plate 21 to remove the workpiece 90, thereby facilitating the operation of removing the workpiece 90 from the support plate 21.

[0048] Each of the riveting devices 30 includes an adjustment component 31 and a riveting gun 32, wherein each adjustment component 31 is disposed on the device body 10, and a riveting gun 32 is moved by an adjustment component 31 to approach above a workpiece 90 located in the limiting space until the riveting end of a riveting gun 32 is aligned with the riveting area of ​​a workpiece 90. Thus, an operator manually operates the riveting gun 32 to perform riveting operations on the riveting area of ​​the workpiece 90.

[0049] In one embodiment, each of the adjustment components 31 is configured as a robotic arm, and the rivet gun 32 is driven and moved to be connected to the robotic arm. That is, through the operation of the robotic arm, the rivet gun 32 is automatically carried to the area above the workpiece 90 to be riveted, thereby performing the riveting operation on the workpiece 90.

[0050] In another embodiment, such as Figure 1As shown, each of the adjustment components 31 includes a fixed base 311, a feed shaft 312, a moving block 313, and a translation member 314, wherein the fixed base 311 is disposed on the device body 10. One feed shaft 312 is vertically arranged so that one end is connected to the top of one of the fixed bases 311. One moving block 313 is connected to one of the feed shafts 312 in a manner that allows rotation and translation along the axial direction of the feed shaft 312, and the translation member 314 is configured to synchronously follow the rotation and translation of one of the moving blocks 313. One rivet gun 32 is moved horizontally by being driven by one of the translation members 314 until the rivet end of one of the rivet gun 32 is aligned with the riveting area of ​​one of the workpieces 90.

[0051] Understandably, in this embodiment, when it is necessary to rivet the workpiece 90 placed in one of the limiting spaces, the operator manually drives a moving block 313 to translate along the axial direction of a corresponding supply axis 312 to above the workpiece 90. At the same time, the moving block 313 is rotated along the axial direction of the corresponding supply axis 312 until a corresponding translation member 314 can drive the rivet gun 32 so that the rivet end of the rivet gun 32 is aligned with the riveting area of ​​the workpiece 90. Then, the moving block 313 is translated along the axial direction of the corresponding supply axis 312 so that the rivet end of the rivet gun 32 is close to the riveting area of ​​the workpiece 90, thereby performing the riveting operation.

[0052] In this way, when the riveting equipment performs a riveting operation on at least one of the workpieces 90, the positioning function of the positioning component 20 eliminates the need for manual positioning of the workpiece 90. As a result, the operator only needs to perform the step of controlling the riveting gun 32 to perform the riveting operation, thereby reducing the number of steps for manual intervention in the riveting operation and improving riveting efficiency.

[0053] Preferably, each of the positioning components 31 has a support portion 3111 at its top end. Each support portion 3111 extends vertically upward and surrounds the outer periphery of a shift shaft 312, so that the end of the corresponding shift shaft 312 connected to the fixed base 311 is surrounded. Thus, the area supported by each shift shaft 312 is increased by the support portion 3111 of the fixed base 311, thereby making the shift shaft 312 stably connected to the top of the fixed base 311.

[0054] Preferably, each of the translational components 314 includes a mounting block 3141, at least one guide post 3142, and a connecting block 3143, wherein the mounting block 3141 is connected to the moving block 313, and at least one guide post 3142 penetrates opposite sides of the mounting block 3141. Each guide post 3142 is movably connected to the mounting block 3141, and the extending direction of each guide post 3142 is parallel to the horizontal movement direction of the rivet gun 32. The connecting block 3143 is located on the side of the mounting block 3141 penetrated by the guide post 3142 and is connected to at least one guide post 3142 penetrating the mounting block 3141. The rivet gun 32 is detachably connected to the connecting block 3143.

[0055] It is understood that when the guide post 3142 moves to the mounting block 3141, the connecting block 3143 is driven to move in the same direction as the extension direction of the guide post 3142, so that the rivet gun 32 is driven to move synchronously. Then, when the rivet gun 32 needs to perform a rivet operation, the rivet gun 32 can move in the same direction as the extension direction of the guide post 3142 until the rivet end of the rivet gun 32 is aligned with the rivet area of ​​a workpiece 90.

[0056] Preferably, each of the moving blocks 313 extends a predetermined length along a direction parallel to the extension direction of each of the guide posts 3142 to form an extension 3131, and one of the mounting blocks 3141 is connected to the extension 3131 of one of the moving blocks 313. In this way, the vertical distance between the mounting block 3141 and the supply shaft 312 is increased. Therefore, when the extension length of each guide post 3142 is predetermined, the vertical distance between the connecting block 3143 and the supply shaft 312 is greater, and the distance that the connecting block 3143 moves along a direction consistent with the extension direction of the guide post 3142 will also increase. Thus, by driving the connecting block 3143 to move a shorter distance, the riveting end of the rivet gun 32 is aligned with the riveting area of ​​a workpiece 90.

[0057] It is worth noting that the vertical distance between one of the mounting blocks 3141 and one of the feed shafts 312 is less than the vertical distance between the corresponding limiting space on the support plate 21 and the corresponding feed shaft 312. That is, the shortest vertical distance between the rivet gun 32 in each rivet device 30 and the feed shaft 312 is less than the vertical distance between the corresponding limiting space on the support plate 21 and the corresponding feed shaft 312, thereby ensuring that the rivet gun 32 of each rivet device 30 can be adjusted so that the rivet end of the rivet gun 32 is aligned with the workpiece 90 in the corresponding limiting space.

[0058] In a preferred embodiment, specifically as follows: Figure 4 As shown, the number of guide posts 3142 in each translation member 314 is set to two, and the two guide posts 3142 pass through a mounting block 3141 in a spaced manner. That is, one connecting block 3143 is connected to two guide posts 3142 at the same time. In this way, the movement of one connecting block 3143 through two guide posts 3142 is more stable than the movement of one connecting block 3143 through one guide post 3142. At the same time, the two guide posts 3142 also share the weight of one connecting block 3143 and one rivet gun 32.

[0059] Furthermore, each of the translational members 314 also includes a limiting block 3144, wherein the limiting block 3144 and the connecting block 3143 in each of the translational members 314 are arranged opposite to each other and spaced apart, and the mounting block 3141 in each of the translational members 314 is held between the limiting block 3144 and the connecting block 3143, and the two ends of each of the guide posts 3142 of each of the translational members 314 are respectively connected to the connecting block 3143 and the limiting block 3144.

[0060] It is understood that when the distance that the connecting block 3143 of one of the translation members 314 moves along the extension direction of each of the guide posts 3142 is equal to the extension length of each of the guide posts 3142, the limiting block 3144 will directly abut against the side of the mounting block 3141 through which the guide posts 3142 penetrate. At this time, the moving distance of the connecting block 3143 reaches its maximum, and each of the guide posts 3142 is difficult to continue moving, thereby preventing the guide posts 3142 from actively detaching from the mounting block 3141.

[0061] Preferably, such as Figure 1 As shown, the device body 10 includes a horizontal platform 11 and a vertical platform 12, wherein the vertical platform 12 is connected to the top edge of the horizontal platform 11, and the vertical platform 12 is arranged to extend in a vertically upward direction so that an operating space 101 is formed between the horizontal platform 11 and the vertical platform 12.

[0062] Additionally, a pair of support platforms 231 in the connecting members 23 of the positioning assembly 20 are connected to the same side of the transverse platform 11 away from the vertical platform 12 in a relative and spaced manner. One of the fixing seats 311 in each of the adjusting assemblies 31 is connected to the top of the transverse platform 11 and is located in the operating space 101.

[0063] Furthermore, the riveting equipment also includes a fault-prevention component 40, which is used to prevent the riveting gun 32 in each of the riveting devices 30 from performing a riveting operation on at least one of the positioned workpieces 90 at a predetermined riveting position.

[0064] Specifically, such as Figure 1 and Figure 4 As shown, the error-proofing component 40 includes at least one detection unit 41 and a controller 42. Each detection unit 41 includes an angle detection element 411 and a linkage member 412. Each angle detection element 411 is communicatively connected to one of the controllers 42, and each angle detection element 411 has a rotatable detection end. The detection end of one angle detection element 411 is connected to the other end of one of the feed shafts 312 away from the fixed base 311. The linkage member 412 in each detection unit 41 is configured to rotate synchronously with one of the moving blocks 313 along the axial direction of one of the feed shafts 312. Furthermore, the angle detection element 411 in each detection unit 41 is driven by one of the linkage members 412 to rotate relative to the axial direction of the corresponding feed shaft 312, and generates a corresponding angle signal.

[0065] The controller 42 is connected to the vertical platform 12 of the device body 10 and is located in the operating space 101, for receiving angle signals transmitted by the angle detection element 411. Each rivet gun 32 is also electrically connected to a power source, and each rivet gun 32 is controllably connected to the controller 42 so that each rivet gun 32 can be controlled by the controller 42 to start and stop.

[0066] It should be noted that each workpiece 90 has a fixed position in each riveting area on different sides after being positioned, and each rivet gun 32 rotates by the moving block 313 at a fixed angle before riveting at least one workpiece 90 in different riveting areas on the same side. Since an angle detection element 411 rotates synchronously with a moving block 313 through a linkage component 412, and the moving block 313 also synchronously drives the corresponding rivet gun 32 to rotate when it is rotated, the rotation angle of the corresponding angle detection element 411 can be used to determine whether the rotation angle of the corresponding rivet gun 32 is a fixed angle.

[0067] Thus, when one of the angle detection elements 411 rotates to a fixed angle, the corresponding angle detection element 411 generates a corresponding angle signal and transmits it to the controller 42. After receiving the angle signal transmitted by the angle detection element 411, the controller 42 sends a control command to the corresponding rivet gun 32. At this time, the corresponding rivet gun 32 is rotated to a fixed angle and can be activated for riveting operations. However, when the angle detection element 411 rotates to a less than fixed angle, the angle detection element 411 will not send an angle signal to the controller 42. In this case, the controller 42 will control the corresponding rivet gun 32 to be in a closed state because it has not yet received an angle signal, making the corresponding rivet gun 32 unusable for riveting operations.

[0068] In this way, through the error prevention component 40, the operator can accurately move the rivet gun 32 in the rivet device 30 to the predetermined rivet position to perform rivet operation on the workpiece 90 positioned on the support plate 21.

[0069] Preferably, each of the angle detection elements 411 is configured as an angle encoder.

[0070] Preferably, specifically as follows Figure 4 As shown, each of the detection units 41's linkage components 412 includes a first linkage block 4121, a second linkage block 4122, a third linkage block 4123, and a driving rod 4124. The first linkage block 4121 and the third linkage block 4123 of each linkage component 412 are respectively disposed at the high end and low end of the same feed shaft 312 in a relative and spaced manner, and are rotatably connected to the same feed shaft 312. The third linkage block 4123 of each linkage component 412 is also held above a corresponding fixed seat 311. The second linkage block 4122 of each detection unit 41 is disposed between the first linkage block 4121 and the third linkage block 4123 and is fixedly connected to a moving block 313. The two ends of the driving rod 4124 are respectively connected to a first linkage block 4121 and a third linkage block 4123, and the driving rod 4124 also passes through a second linkage block 4122 and is axially parallel to a transfer shaft 312. Furthermore, the second linkage block 4122 is movably connected to the driving rod 4124.

[0071] The angle detection element 411 in each of the detection units 41 is connected to the first linkage block 4121 so that the detection end of the angle detection element 411 is connected to the end of a corresponding shift shaft 312 away from the fixed base 311.

[0072] It is understood that when a moving block 313 is driven to rotate along the axial direction of a corresponding supply shaft 312, the second linkage block 4122 in the corresponding linkage member 412 is driven to rotate synchronously along the axial direction of the corresponding supply shaft 312. Since the driving rod 4124 in the corresponding linkage member 412 passes through the second linkage block 4122, the driving rod 4124 is driven to rotate synchronously with the second linkage block 4122. At the same time, the first linkage block 4121 and the third linkage block 4123 are driven to rotate synchronously by the rotating driving rod 4124, thereby causing the detection end of an angle detection element 411 connected to the first linkage block 4121 to be rotated relative to form a corresponding angle signal.

[0073] Preferably, each of the first linkage blocks 4121 of the linkage member 412 has a connecting portion 41211, each connecting portion 41211 extending in a vertically upward direction and at least partially extending beyond the high end of one of the supply shafts 312. One of the angle detection elements 411 is connected to the connecting portion 41211 of one of the first linkage blocks 4121 and is coaxial with the corresponding supply shaft 312.

[0074] More preferably, the second linkage block 4122 in each of the linkage components 412 also has a through hole, the diameter of which is set to be larger than the size of the corresponding one of the transfer shafts 312, so that the corresponding one of the transfer shafts 312 can pass through freely.

[0075] Preferably, the controller 42 is configured as a control circuit board with control circuitry to control the start and stop of each of the rivet guns 32.

[0076] Furthermore, each of the linkage components 412 also includes a pair of limiting blocks 4125, specifically as follows: Figure 4As shown, in each of the linkage components 412, a pair of limiting blocks 4125 are connected to the lower end of the same supply shaft 312, and the two limiting blocks 4125 in the pair are arranged opposite to each other and spaced apart on the same supply shaft 312. The third linkage block 4123 of each linkage component 412 is disposed between the two limiting blocks 4125 in the pair, thereby limiting the third linkage block 4123 of each linkage component 412 by the two limiting blocks 4125, making each linkage component 412 as a whole subject to force and difficult to disengage from the corresponding supply shaft 312.

[0077] In addition, the riveting device also includes at least one balancer 50, one of which is used to put the rivet gun 32 in one of the riveting devices 30 in a weightless state, thereby reducing the gravitational influence of each rivet gun 32 on the corresponding translation member 314 and facilitating the operation of driving the moving block 313 to rotate and translate.

[0078] Preferably, each of the balancers 50 is connected to the top of the vertical platform 12 and held above the horizontal platform 11, and each of the balancers 50 has a retractable suspension end for connection to a rivet gun 32. That is, when a rivet gun 32 performs a rivet operation, the suspension end of the corresponding balancer 50 automatically retracts and applies an upward pulling force to the rivet gun 32, so that the suspension end of the balancer 50 shares part of the weight of a rivet gun 32, thereby reducing the overall weight of the corresponding translation member 314.
