[0049] In order to make the objectives, technical solutions and advantages of the present disclosure more clear, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.

[0050] This embodiment relates to a punching line crossbar device, referring to Figure 1 As shown, the crossbar device of the punching line includes a crossbar body 1, at least two mounting bases 2 and a main rod 3. Among them, at least two mounting bases 2 are mounted on the crossbar body 1 and are spaced apart along the axial direction of the crossbar body 1. For example, Figure 1 In the embodiment, the number of the mounting bases 2 can be two, but the number of the mounting bases 2 can also be three, four or six. Figure 1The number of mounting bases 2 shown is two as an example.

[0051] Continue to refer Figure 1 As shown, at least two mounting bases 2 each have a first fixing assembly 21. For example Figure 1 As shown, both mounting bases 2 may have a first fixing assembly 21 .

[0052] Continue to refer Figure 1 As shown, the main rod 3 is suitable for connecting with a plurality of first end effectors 5 , and the plurality of first end effectors 5 are distributed at intervals along the axial direction of the main rod 3 .

[0053] For example, in Figure 1 In the embodiment, the main rod 3 can be connected to three first end pickers 5, and the three first end pickers 5 can be distributed at intervals along the axial direction of the main rod 3. However, the main rod 3 can also be connected to two, four or five first end pickers 5, and correspondingly, the two, four or five first end pickers 5 connected to the main rod 3 can be distributed at intervals along the axial direction of the main rod 3.

[0054] Continue to refer Figure 1 As shown, the main rod 3 and the crossbar body 1 are parallel to each other, and the main rod 3 and at least two mounting bases 2 are detachably connected through corresponding first fixing components 21. Figure 1 As shown, the main rod 3 and the two mounting bases 2 are detachably connected via corresponding first fixing components 21 .

[0055] As can be seen from the above, the main rod 3 and at least two mounting bases 2 are detachably connected through the corresponding first fixing components 21. At the same time, since the plurality of first end-effectors 5 are connected to the main rod 3, and the at least two mounting bases 2 connected to the main rod 3 are installed on the crossbar body 1. Therefore, by disassembling and connecting the main rod 3 and the mounting base 2, the plurality of first end-effectors 5 can be disassembled and installed on the crossbar body 1 at the same time, the installation efficiency is high, and the problem of installation error is not easy to occur.

[0056] Furthermore, the main rod 3 and the crossbar body 1 are parallel to each other, and at least two mounting bases 2 are spaced apart along the axial direction of the crossbar body 1. Therefore, the main rod 3 can be stably connected to the crossbar body 1 through at least two mounting bases 2.

[0057] In one example, reference Figure 1 Combined with Figure 2 As shown, there are two main rods 3. The mounting base 2 is annular and is sleeved on the crossbar body 1. At least two mounting bases 2 each have two first fixing components 21, and the two first fixing components 21 of at least two mounting bases 2 each correspond to the two main rods 3, respectively. The two main rods 3 are detachably connected to the at least two mounting bases 2 through the corresponding first fixing components 21, and the two main rods 3 are respectively located on opposite sides of the crossbar body 1. For example Figure 1 As shown, the two main rods 3 are detachably connected to the two mounting bases 2 through corresponding first fixing components 21 .

[0058] In this way, the two main rods 3 can connect more first end pickers 5, and are conducive to picking up and placing more types of workpieces. At the same time, the two main rods 3 are respectively located on two opposite sides of the crossbar body 1, which is conducive to improving the stability when picking up and placing the workpiece.

[0059] In one example, the mounting base 2 is conveniently mounted on the crossbar body 1. Figure 2 As shown, the mounting base 2 may include two first assembly plates 201 and two second assembly plates 202. The first first assembly plate 201, the first second assembly plate 202, the second first assembly plate 201 and the second second assembly plate 202 may be detachably connected end to end to form a ring. The first fixing assembly 21 connected to the two main rods 3 may be installed on the two first assembly plates 201 or the two second assembly plates 202, respectively. For example, Figure 2 In the embodiment, the two first fixing components 21 can be respectively installed on the two first combination plates 201, but it can also be that the two first fixing components 21 can be respectively installed on the two second combination plates 202. Figure 2 The two first fixing components 21 shown are respectively installed on the two first combination plates 201 as an example.

[0060] In an example, the mounting base 2 may further include four groups of second fixing members, each group of second fixing members including a plurality of rod-shaped second fixing members. Figure 2 As shown, the first assembly board 201 has a plurality of third mounting holes 2011 on both sides opposite to each other, and the second assembly board 202 has a plurality of fourth mounting holes 2021 on both sides opposite to each other. The second fixing members of each set of second fixing members correspond one to one with the third mounting holes 2011 on one side of the first assembly board 201 and one to one with the fourth mounting holes 2021 on one side of the second assembly board 202.

[0061] For example, in Figures 5 to 7 In the embodiment, the number of the third mounting holes 2011 on one side of a first assembly board 201 may be four, and the number of the fourth mounting holes 2021 on one side of a second assembly board 202 may be four, and each group of second fixing members may include four second fixing members. However, the number of the third mounting holes 2011 on one side of a first assembly board 201 may also be three, five, or six, and correspondingly, the number of the fourth mounting holes 2021 on one side of a second assembly board 202 may also be three, five, or six, and each group of second fixing members may also include three, five, or six, and the like.

[0062] Furthermore, each second fixing member can pass through the corresponding third mounting hole 2011 and fourth mounting hole 2021 in sequence, so that the first first combination plate 201, the first second combination plate 202, the second first combination plate 201 and the second second combination plate 202 can be fixedly connected in a detachable manner in sequence through four groups of second fixing members.

[0063] In one example, the second fixing member may be a bolt. For example, the nut at the first end of the bolt abuts against the first assembly plate 201, and the second end of the bolt passes through the third mounting hole 2011 and is screwed into the fourth mounting hole 2021. The fourth mounting hole 2021 is a bolt hole. Thus, a first assembly plate 201 and a second assembly plate 202 are fixedly connected.

[0064] In another example, the second fixing member may also be a pin. For example, the first end of the pin has a pin cap that abuts against the first assembly board 201, and the second end of the pin passes through the third mounting hole 2011 and the fourth mounting hole 2021 in sequence and is riveted to the second assembly board 202. Thus, a first assembly board 201 and a second assembly board 202 are fixedly connected.

[0065] In another example, the second fixing member may also be a screw, the first end of the screw having a screw cap abutting against the first assembly board 201, the second end of the screw passing through the third mounting hole 2011 and screwed into the fourth mounting hole 2021, wherein the fourth mounting hole 2021 is a screw hole. Thus, a first assembly board 201 and a second assembly board 202 are fixedly connected.

[0066] In one example, the third mounting hole 2011 may be a countersunk slot hole, thereby reducing the space that the second fixing member may occupy. For example, the second fixing member may be a bolt, and the nut of the bolt may be located in the countersunk slot of the countersunk slot hole. For another example, the second fixing member may be a pin, and the pin cap of the pin may be located in the countersunk slot of the countersunk slot hole. For another example, the second fixing member may be a screw, and the screw cap of the screw may be located in the countersunk slot of the countersunk slot hole.

[0067] In one example, reference Figure 3 As shown, the first fixing assembly 21 includes a first half ring 211, a second half ring 212 and a first fixing member 213. The first half ring 211 is connected to the corresponding mounting base 2. For example, the first half ring 211 can be connected to the first assembly plate of the corresponding mounting base 2. The first half ring 211 and the corresponding second half ring 212 are detachably connected through the corresponding first fixing member 213, so that the first half ring 211 and the corresponding second half ring 212 are surrounded to form a fixing ring, which is sleeved on the main rod 3 and has an interference fit with the main rod 3.

[0068] Thus, the connection and disassembly of the main rod 3 and the mounting base 2 can be realized by connecting and disassembling the first half ring 211 and the second half ring 212, and the first end pick 5 can be quickly replaced. In addition, the main rod 3 can be clamped by the first half ring 211 and the second half ring 212, which is beneficial to improving the rigidity and strength of the main rod 3 and avoiding stress concentration compared to directly connecting the main rod 3 and the mounting base 2 by bolts, clamping, etc., so that the main rod 3 is not easily damaged by problems such as fracture, which is beneficial to improving the service life of the main rod 3.

[0069] In one example, reference Figure 1 Combined with Figure 8 As shown, the cross section of the main rod 3 is circular, and the first end tool 5 has an annular clamping structure 51, which is sleeved on the main rod 3 and has an interference fit with the main rod 3. Therefore, since the cross section of the main rod 3 is circular, when the annular clamping structure 51 releases the main rod 3, the first end tool 5 can rotate around the main rod 3 at any angle, and then clamp the main rod 3 through the annular clamping structure 51, thereby conveniently adjusting the angle of the first end tool 5.

[0070] For example, the annular clamping structure 51 may include two third half rings, which are connected end to end to form a complete ring, wherein one end of the two third half rings can be rotatably connected, and the other end can be detachably fixedly connected by means of a clamping connection, a bolt, etc.

[0071] In one example, if Figure 8 As shown, the annular clamping structure 51 may also include two third fixing members, and both ends of the two third half rings may have fifth mounting holes 511. The two third fixing members are respectively located at one end of the third half ring, and the third fixing members may sequentially pass through the two fifth mounting holes 511 at one end corresponding to the two third half rings, thereby realizing a detachable fixed connection between the two third half rings. For example, the third fixing member may be a bolt, a screw, etc.

[0072] In one example, reference Figure 3 As shown, the first fixing member 213 is rod-shaped, and the number of the first fixing members 213 is at least two. In addition, the first half ring 211 has at least two first mounting holes 2111, which are symmetrically located on both sides of the main rod 3, and the first mounting holes 2111 correspond to the first fixing members 213 one by one. At the same time, the second half ring 212 has at least two second mounting holes 2121, and the second mounting holes 2121 correspond to the first fixing members 213 one by one.

[0073] For example, the first half ring 211 may have any even number of first mounting holes 2111, such as two first mounting holes 2111, four first mounting holes 2111, or six first mounting holes 2111, so that the number of first mounting holes 2111 on both sides of the main rod 3 may be equal. Accordingly, the number of first fixing members 213 may also be two, four, or six, etc., and the number of second mounting holes 2121 of the second half ring 212 may also be two, four, or six, etc., so that the first fixing members 213 may correspond to the first mounting holes 2111 and the second mounting holes 2121 one by one.

[0074] The first fixing member 213 passes through the corresponding second mounting hole 2121 and the corresponding first mounting hole 2111 in sequence, so that the first half ring 211 and the second half ring 212 can be detachably connected through the first fixing member 213. For example, the first fixing member 213 can be a bolt, a pin or a screw.

[0075] As described above, the first half ring 211 and the second half ring 212 can be reliably connected by at least two first fixing members 213 .

[0076] In one example, reference Figure 3 and Figure 4 As shown, the first fixing assembly 21 further includes a T-shaped connecting portion 216 , two limiting blocks 214 and an adjusting member 215 . The T-shaped connecting portion 216 includes a vertical extending portion 2161 and a horizontal extending portion 2162 .

[0077] The first end of the vertical extension portion 2161 is connected to the side of the first half ring 211 away from the second half ring 212, and the second end of the vertical extension portion 2161 extends toward the mounting base 2. The middle of the transverse extension portion 2162 is connected to the second end of the vertical extension portion 2161, and the two ends of the transverse extension portion 2162 extend toward opposite sides along the surface of the mounting base 2. For example, the first half ring 211, the vertical extension portion 2161 and the transverse extension portion 2162 can be integrally formed, or can be independent structural parts that are fixedly connected together by bolts, welding, etc.

[0078] Continue to refer Figure 3 As shown, the two limiting blocks 214 correspond to the two ends of the transverse extension portion 2162 respectively, and at least a portion of the limiting block 214 is located on a side of the corresponding end of the transverse extension portion 2162 away from the mounting base 2.

[0079] The adjusting member 215 is used to adjust the distance between the stop block 214 and the mounting base 2. Thus, by reducing the distance between the stop block 214 and the mounting base 2, the stop block 214 can press the corresponding end of the transverse extension portion 2162 toward the mounting base 2, thereby achieving the fixation between the first half ring 211 and the mounting base 2. At the same time, by increasing the distance between the stop block 214 and the mounting base 2, the first half ring 211 and the mounting base 2 can be separated.

[0080] Therefore, reliable connection and convenient disassembly between the first half ring 211 and the mounting base 2 can be achieved through the T-shaped connecting portion 216 , the two limiting blocks 214 and the adjusting member 215 .

[0081] In one example, continue to refer to Figure 4 As shown, the adjusting member 215 may be a bolt, a pin or a screw, etc., the limiting block 214 and the mounting base 2 may both have a sixth mounting hole 23, and the adjusting member 215 may pass through the sixth mounting hole 23 of the limiting block 214 and be threadedly connected with the sixth mounting hole 23 of the mounting base 2. Figure 3 and Figure 4 As shown, the limit block 214 and the first combination plate 201 may both have a sixth mounting hole 23. Taking the adjusting member 215 as a bolt as an example, the nut of the adjusting member 215 may be against the limit block 214, so that the limit block 214 and the mounting base 2 can be clamped or loosened on the lateral extension portion 2162 by rotating the adjusting member 215.

[0082] In one example, reference Fig. 9 and Fig.10 As shown, the main rod 3 has a locking block 31 near the first end. A mounting base 2 has a second fixing component 22. Accordingly, in order to realize the simultaneous installation of the second fixing component 22 and the first fixing component 21 on the mounting base 2, the mounting base 2 with the second fixing component 22 can be composed of two parts as shown in FIG. Fig.12 The second first combination plate 201 and two Fig.14 The second combined panels 202 are connected together.

[0083] The second fixing assembly 22 includes a fixing seat 221, a rotating member 222 and a positioning member 223. Fig. 9 As shown, the fixing seat 221 is installed on the corresponding mounting base 2, for example Fig.10 As shown, the fixing seat 221 can be fixedly mounted on the corresponding first assembly plate 201 by means of bolts, clamping, etc. Fig.11 As shown, the first end of the main rod 3 can abut against the fixing seat 221 along the axial direction of the main rod 3 .

[0084] refer to Fig.12 Combined with Fig.11As shown, the rotating member 222 is rotatably connected to the corresponding fixed seat 221 around the first axis, and the rotating member 222 has a limiting groove 2221 with an opening on one side. The limiting groove 2221 extends along a circular trajectory centered on the first axis, wherein the first axis is perpendicular to the main rod 3.

[0085] Among them, the locking block 31 is located on a circular track. When the rotating member 222 is rotated, the locking block 31 can enter the limiting groove 2221 from the opening of the limiting groove 2221, and when the locking block 31 is located in the limiting groove 2221, the positioning member 223 is used to limit the rotation of the rotating member 222.

[0086] Therefore, when the locking block 31 is located in the limiting groove 2221 and the positioning member 223 limits the rotation of the rotating member 222, the possible axial movement and rotation of the main rod 3 can be limited, further improving the stability of the connection between the main rod 3 and the mounting base 2.

[0087] In one example, reference Fig.10 and Fig.12 As shown, the positioning member 223 is rod-shaped, and both the fixed seat 221 and the rotating member 222 have a first positioning hole 224. When the locking block 31 is located in the limiting groove 2221, the positioning member 223 can sequentially pass through the first positioning hole 224 of the rotating member 222 and the first positioning hole 224 of the fixed seat 221. For example, the positioning member 223 can be a bolt, a pin or a screw, etc. The positioning member 223 can be threadedly connected with the first positioning hole 224 of the rotating member 222, and can also extend into the first positioning hole 224 of the fixed seat 221.

[0088] Therefore, by twisting the positioning member 223 , the positioning member 223 extends into the first positioning hole 224 of the fixing seat 221 to restrict the rotation of the rotating member 222 , or leaves the first positioning hole 224 of the fixing seat 221 to no longer restrict the rotation of the rotating member 222 .

[0089] In one example, continue to refer to Fig.10 and Fig.12 As shown, the fixing seat 221 also has a second positioning hole 225, and the positioning member 223 can sequentially pass through the first positioning hole 224 and the second positioning hole 225 of the rotating member 222. When the positioning member 223 sequentially passes through the first positioning hole 224 and the second positioning hole 225 of the rotating member 222, the locking block 31 is located outside the limiting groove 2221. For example, the second axis of the first positioning hole 224 and the third axis of the second positioning hole 225 can be parallel to the first axis, and the distance between the second axis and the first axis and the distance between the third axis and the first axis can be equal.

[0090] In this way, when the positioning member 223 passes through the first positioning hole 224 and the second positioning hole 225 of the rotating member 222 in sequence, the rotation of the rotating member 222 can be restricted. Meanwhile, the limiting groove 2221 will not restrict the movement of the main rod 3 .

[0091] In one example, continue to refer to Fig.12 As shown, the rotating member 222 may be in the shape of a wrench, so that the rotating member 222 can be easily rotated by a handle.

[0092] In one example, the punching line crossbar device further includes a driving member 4. At least two mounting bases 2 are movably mounted on the crossbar body 1 along the axial direction of the crossbar body 1, and at least one mounting base 2 is connected to the driving member 4, so that the mounting base 2 is driven by the driving member 4 to move along the axial direction of the crossbar body 1. Thus, the first end tool 5 can be driven to move along the axial direction of the crossbar body 1.

[0093] For example Figure 1 As shown, the driving member 4 can be a cylinder, the fixed part of the cylinder can be fixedly connected to the crossbar body 1, the moving part of the cylinder can be connected to the mounting base 2, and the cylinder can be extended and retracted along the axial direction of the crossbar body 1. For example, the fixed part of the cylinder can be fixedly connected to the crossbar body 1 by bolts, rivets, etc. Fig.13 and Fig.14 As shown, the second assembly plate 202 may have a cylinder connector 2022, and the cylinder connector 2022 and the second assembly plate 202 may be integrally formed, or may be independent structural members, and may be fixedly connected together by bolts, welding, etc. The moving part of the cylinder and the cylinder connector 2022 may both have a seventh mounting hole 2023, and the stamping line crossbar device further includes a rod-shaped fourth fixing member, which may be a bolt, a pin, or a screw, etc. The fourth fixing member may sequentially pass through the seventh mounting hole 2023 of the moving part of the cylinder and the seventh mounting hole 2023 of the cylinder connector 2022, thereby realizing the connection between the moving part of the cylinder and the second assembly plate 202.

[0094] In one example, the crossbar device of the punching line further includes a plurality of guide wear-resistant strips 6. The crossbar body 1 has a square cross section. The plurality of guide wear-resistant strips 6 are respectively installed on four sides of the crossbar body 1 and extend along the axial direction of the crossbar body 1. Figure 2 and Fig. 9 As shown in , the number of guide wear strips 6 can be eight, and two guide wear strips 6 can be installed on each of the four faces of the square crossbar body 1, for example, the guide wear strips 6 can be fixedly connected to the crossbar body 1 by gluing. In addition, the mounting base 2 is annular, and the mounting base 2 is sleeved on the crossbar body 1 and abuts against the multiple guide wear strips 6.

[0095] As described above, the cross bar body 1 may rotate under the drive of the manipulator, and since the mounting base 2 is annular and is sleeved on the cross bar body 1, no matter how the cross bar body 1 rotates, the stability of the mounting base 2 on the cross bar body 1 can be equally guaranteed, which can effectively improve the service life of the cross bar device of the stamping line.

[0096] In one example, the press line crossbar device further includes a base connector 7, and at least two mounting bases 2 are fixedly connected to the base connector 7. For example, the base connector 7 and the first connecting plate 201 can be fixedly connected by bolts, welding, etc. Thus, the base connector 7 can connect at least two mounting bases 2 together, so that the base connector 7 serves as the main force-bearing structural member when the mounting base 2 moves, thereby avoiding damage to the main rod 3.

[0097] In one example, the first combined plate 201 and the second combined plate 202 both have a plurality of de-weighting holes 24 that are spaced apart. Figure 7 As shown, the number of the de-weighting holes 24 of the first type of first combination plate 201 may be four, but may also be five, six or eight. Fig.14 As shown, the number of the de-weighting holes 24 of the second type of first combined plate 201 may be four, but may also be five, six, or eight.

[0098] In the embodiment of the present disclosure, the main rod 3 and at least two mounting bases 2 are detachably connected through the corresponding first fixing components 21. At the same time, since the plurality of first end-effectors 5 are connected to the main rod 3, and the at least two mounting bases 2 connected to the main rod 3 are installed on the crossbar body 1. Therefore, by disassembling and connecting the main rod 3 and the mounting base 2, the plurality of first end-effectors 5 can be disassembled and installed on the crossbar body 1 at the same time, the installation efficiency is high, and the problem of installation error is not easy to occur.

[0099] Furthermore, the main rod 3 and the crossbar body 1 are parallel to each other, and at least two mounting bases 2 are spaced apart along the axial direction of the crossbar body 1. Therefore, the main rod 3 can be stably connected to the crossbar body 1 through at least two mounting bases 2.

[0100] An old press line crossbar device such as Fig.17 As shown, the conventional crossbar device of the punching line includes a crossbar body 1 , a driving member 4 , a plurality of slide blocks 91 , a guide rail 92 and a plurality of end tool mounting seats 93 .

[0101] Among them, a plurality of slider mounting seats 11 are inlaid on the crossbar body 1, and the plurality of slider mounting seats 11 are distributed at intervals along the axial direction of the crossbar body 1. The sliders 91 correspond to the slider mounting seats 11 one by one, and the sliders 91 and the slider mounting seats 11 can be detachably fixedly connected by bolts. The guide rail 92 extends along the axial direction of the crossbar body 1 and slidably cooperates with the plurality of sliders 91. The driving member 4 is detachably connected to the guide rail 92 and is used to drive the sliding of the guide rail 92. Multiple end picker mounting seats 93 can be detachably mounted on the guide rail 92 by bolts, and the plurality of end picker mounting seats 93 are distributed at intervals along the axial direction of the crossbar body 1. The second end picker 94 can be detachably mounted on the end picker mounting seat 93.

[0102] When replacing the second end pick-up 94 of the old stamping line crossbar device, it is necessary to remove each second end pick-up 94 from the end pick-up mounting seat 93 one by one, and then install the replaced second end pick-ups 94 one by one on the end pick-up mounting seat 93. This not only has a large workload and low work efficiency, but is also prone to installation errors.

[0103] In order to improve the efficiency of replacing the end picker of the old press line cross bar device, so that the old press line cross bar device can be installed with the first end picker 5, accordingly, this embodiment also provides a method for modifying the press line cross bar device, which is used to modify the old press line cross bar device into any press line cross bar device including the driving member 4 of the first aspect, and includes the following steps:

[0104] First, the multiple end-tool mounting seats 93, the guide rails 92 and the multiple sliders 91 on the crossbar body 1 are removed in sequence, and the portions of the multiple slider mounting seats 11 on the crossbar body 1 protruding from the outer surface of the crossbar body 1 are removed by machining, and then the installation of at least two mounting bases 2 and the main rod 3 is completed. Thus, the old press line crossbar device can be converted into any press line crossbar device of the first aspect, so that not only the conversion steps are relatively simple, but also the crossbar body 1 and the driving member 4 are retained, saving costs.

[0105] In the disclosed embodiment, the main rod 3 and at least two mounting bases 2 are detachably connected through the corresponding first fixing components 21. At the same time, since a plurality of first end pickers 5 are connected to the main rod 3, and at least two mounting bases 2 connected to the main rod 3 are mounted on the crossbar body 1. Therefore, the stamping line crossbar device obtained by modifying the old stamping line crossbar device can realize the disassembly and installation of the plurality of first end pickers 5 on the crossbar body 1 by disassembling and connecting the main rod 3 and the mounting base 2, and the installation efficiency is high, and the problem of installation error is not easy to occur.

[0106] Furthermore, the main rod 3 and the crossbar body 1 are parallel to each other, and at least two mounting bases 2 are spaced apart along the axial direction of the crossbar body 1. Therefore, the stamping line crossbar device modified from the old stamping line crossbar device can achieve a stable connection of the main rod 3 on the crossbar body 1 through at least two mounting bases 2.
