Description
Technical Field
[0001] The utility model relates to the technical field of guide wire processing, in particular to a core wire elbow forming machine. Background Art
[0002] A guide wire consists of a core wire and a flexible sleeve, and this guide wire needs to form a U-shaped elbow structure at one end. When making the guide wire, one end of the core wire is first flattened and then the elbow is formed to ensure the stability of the elbow, and then the flexible sleeve is installed. During processing, the guide wire needs to be manually sent to the flattening equipment to flatten the end, and then the elbow equipment is used to bend the flattened end. The process is relatively cumbersome and reduces production efficiency. Utility Model Content
[0003] The utility model aims to provide a core wire elbow forming machine to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.
[0004] The technical solution adopted to solve the above-mentioned technical problems is as follows: a core wire elbow forming machine, comprising: a flattening component, comprising a first support seat, the first support seat is rotatably mounted with a fixed pressure roller and a slidably mounted with a pressure block, the first support seat is mounted with a fixed roller motor for driving the fixed pressure roller to rotate, the pressure block is rotatably mounted with a dynamic pressure roller, the pressure block is mounted with a dynamic roller motor for driving the dynamic pressure roller to rotate, the first support seat is mounted with a first driving member for driving the pressure block to move toward or away from the fixed pressure roller, a first gap is spaced between the fixed pressure roller and the dynamic pressure roller; an elbow component, comprising a second support seat, the second support seat is rotatably mounted with a winding shaft, the second support seat is mounted with a winding motor for driving the winding shaft to rotate, a clamping knife is mounted on one side of the winding shaft, a second gap is spaced between the winding shaft and the clamping knife, and the position of the first gap corresponds to the position of the second gap.
[0005] This technical solution has at least the following beneficial effects: one end of the core wire to be processed is first fed into the first gap, at this time, the first driving member is driven to drive the pressure block to approach the fixed pressure roller, so that the fixed pressure roller and the dynamic pressure roller can clamp the core wire, and at the same time, the fixed roller motor and the dynamic roller motor are driven to drive the fixed pressure roller and the dynamic pressure roller to rotate in opposite directions respectively, so that during the wire feeding process, one end of the core wire is flattened, and after the front section of the core wire is flattened to the required length, the first driving member is driven to drive the pressure block away from the fixed pressure roller, so that the rear section of the core wire is no longer flattened; at this time, the wire is continued to be fed, and the flattened end of the front section of the core wire will extend into the second gap, and the winding motor is driven to rotate around the axis, so that the flattened end of the front section of the core wire can be bent into shape, and finally, one end of the core wire can be flattened and then bent through a continuous wire feeding process, reducing the trouble of separate processing, improving production efficiency, and also improving the quality of the flattening and bending of the core wire.
[0006] As a further improvement of the above technical solution, the clamping knife is connected to the winding shaft in a sliding manner along the axial direction of the winding shaft, and the rotation of the winding shaft can drive the clamping knife to rotate. The second support seat is equipped with a second driving member for driving the clamping knife to slide. In the initial state, the clamping knife can slide a certain distance along the axial direction of the winding shaft, so that the second gap deviates from the position corresponding to the first gap. After one end of the core wire is flattened, continuing to feed the wire will cause the flattened end of the core wire to be in a position adjacent to the second gap. Then, by driving the second driving member, the clamping knife can be driven to move, so that the flattened end of the core wire enters the second gap from the opening on one side of the second gap, thereby ensuring that the core wire can easily enter the second gap and improving the reliability of the elbow assembly. In addition, when the core wire is in the second gap and bends, the second driving member can drive the clamping knife to offset in the direction away from the core wire. When the core wire bends, it collides with one side of the clamping knife and generates friction. When the clamping knife offsets, it can drive the core wire to offset in the axial direction. When the bending angle of the core wire is large, the end of the core wire and the post-bend or unbend part have an offset in the direction of the axial axis. Therefore, the end of the core wire and the post-bend or bent part are not easy to interfere with each other, and the clamping knife is not easy to interfere with the core wire after offset, thereby ensuring the quality and reliability of the core wire bending.
[0007] As a further improvement of the above technical solution, the winding shaft is installed with a fixing ring, a notch is provided on one side of the fixing ring, a bolt is installed near the notch of the fixing ring, and a slide groove is provided on the fixing ring for the knife clamp to slide. The fixing ring is sleeved on the winding shaft, and the notch position is reduced by installing the bolt, so that the fixing ring can be clamped on the winding shaft, so that the fixing ring can be installed on the winding shaft, and the knife clamp is embedded in the slide groove. When the winding shaft rotates, the knife clamp can be driven to rotate together, but the sliding of the knife clamp relative to the winding shaft is not affected. In addition, by rotating the fixing ring relative to the winding shaft and then fixing it, it is also convenient to adjust the position of the knife clamp relative to the circumference of the winding shaft, so as to adjust the initial position of the knife clamp.
[0008] As a further improvement of the above technical solution, the second driving member includes a push block slidably mounted on the second support seat along the axial direction of the winding shaft, the second support seat is equipped with a shaft-pushing telescopic cylinder for driving the push block to slide, the push block is rotatably mounted with a connecting block, the winding shaft is penetrated by the connecting block, and the clamping knife is connected to the connecting block. By driving the shaft-pushing telescopic cylinder, the push block is driven to slide, thereby driving the connecting block and the clamping knife to move forward and backward along the axial direction of the winding shaft, realizing the movement of the clamping knife sliding relative to the winding shaft, and when the clamping knife slides relative to the winding shaft, the connecting block and the winding shaft also slide relatively, playing a role of positioning and guiding, thereby improving the stability of the sliding of the clamping knife.
[0009] As a further improvement of the above technical solution, a guide assembly is provided between the first gap and the second gap, and the guide assembly includes a clamping claw cylinder installed on the first support seat or the second support seat, and claw discs are installed at both output ends of the clamping claw cylinder, and guide grooves are provided on opposite sides of the two claw discs, and the positions of the two ends of the guide grooves correspond to the positions of the first gap and the second gap respectively. After the core wire is flattened by the flattening assembly, the clamping claw cylinder drives the two claw discs to start covering, and the end of the core wire can just extend from one end of the guide groove into between the two claw discs. When the core wire continues to be fed, the direction of the flattened end of the core wire after extending from the two covered claw discs is more stable and straight, so that the core wire can more easily enter the position corresponding to the second gap in the elbow assembly to perform elbow operations, thereby ensuring the quality of the elbow.
[0010] As a further improvement of the above technical solution, the first driving member includes a cam rotatably mounted on the first supporting seat, the outer periphery of the cam presses against the side of the pressing block away from the fixed pressure roller, the first supporting seat is equipped with a pressing motor for driving the cam to rotate, and an elastic member is installed between the pressing block and the first supporting seat, and the elastic member can provide an elastic force to make the pressing block slide in a direction away from the fixed pressure roller. By driving the pressing motor to drive the cam to rotate, the protruding side of the cam will press against the pressing block, so that the pressing block overcomes the elastic force of the elastic member and slides, thereby making the dynamic pressure roller and the fixed pressure roller on the pressing block approach each other, shortening the width of the first gap, and driving the fixed roller motor and the dynamic roller motor to drive the fixed pressure roller and the dynamic pressure roller to rotate respectively, so that the core wire passing through the first gap can be flattened. The pressing motor is driven to drive the cam to continue to rotate, and the pressing block can continue to keep in contact with the cam under the elastic force of the elastic member, thereby increasing the width of the first gap, and the core wire part passing through the first gap later is not flattened.
[0011] As a further improvement of the above technical solution, the elbow assembly also includes a base, and the second support seat is slidably arranged on the base in a direction close to or away from the first support seat, and the base is equipped with a wire-inserting telescopic cylinder for driving the second support seat to slide. When the core wire extends from the flattening assembly, the wire-inserting telescopic cylinder can drive the elbow assembly as a whole to approach the flattening assembly, so that the position of the second gap is closer to the position of the first gap, so as to ensure that the core wire can extend into the second gap faster after passing through the first gap, and prevent one end of the core wire from extending too much, causing the end to bend due to the influence of gravity, and finally leading to the situation that the second gap cannot be inserted, and then continue to feed the core wire while driving the wire-inserting telescopic cylinder away from the flattening assembly, so as to provide sufficient space for the elbow assembly to bend the end of the core wire, and then ensure the reliability of the elbow assembly to bend the flattened core wire.
[0012] As a further improvement of the above technical solution, it also includes a wire feeding assembly, the wire feeding assembly includes a third support seat, the third support seat is slidably mounted with a wire feeding seat in a direction close to or away from the first support seat, the third support seat is mounted with a wire feeding telescopic cylinder for driving the wire feeding seat to slide, a side plate is mounted on one side of the wire feeding seat, a clamping telescopic cylinder is mounted on the side plate, a clamping block is mounted on the output end of the clamping telescopic cylinder, the wire feeding seat is provided with a wire feeding groove, the two sides of the wire feeding groove are inclined, the top of the wire feeding seat is provided with a clamping groove for the clamping block to engage, and the clamping groove is connected to the wire feeding groove. The core wire is placed in the wire feeding groove at the top of the wire feeding seat, and the clamping block is driven to be embedded in the clamping groove by driving the clamping telescopic cylinder so that the core wire can be clamped, and then the core wire can be sent into the flattening assembly for flattening operation by driving the wire feeding telescopic cylinder, thereby reducing the trouble of manual flattening and improving production efficiency. At the same time, it can also reduce the instability of manual wire feeding, ensure the stability of wire feeding, and further improve the quality of core wire flattening and elbow.
[0013] As a further improvement of the above technical solution, a positioning telescopic cylinder is installed on one side of the first support seat close to the wire feeding seat, and a positioning plate located between the wire feeding seat and the fixed pressure roller is installed at the output end of the positioning telescopic cylinder. When the core wire is placed in the wire feeding slot, one end of the core wire close to the flattening assembly is made to touch the positioning plate to achieve positioning of the end of the core wire. After the core wire is clamped and temporarily fixed on the wire feeding seat, the positioning telescopic cylinder is driven to retract the positioning plate to prevent the positioning plate from interfering with the wire feeding of the core wire. After positioning one end of the core wire, when the core wire enters the flattening assembly for flattening operation, the flattening length can be grasped more accurately, and at the same time, the uniformity of the flattened length of each core wire can be guaranteed.
[0014] As a further improvement of the above technical solution, it also includes a discharging assembly, the discharging assembly includes a fourth support seat, the fourth support seat is rotatably mounted with a dial shaft, the fourth support seat is mounted with a discharging motor for driving the dial shaft to rotate, and both ends of the dial shaft are vertically mounted with dial rods, one of the dial rods is between the first gap and the second gap, and the other of the dial rods is located on the side of the first gap away from the second gap. After the core wire completes the operation of flattening the rear elbow, one end of the core wire is wound on the winding shaft, and the other end or the middle of the core wire is still between the fixed pressure roller and the dynamic pressure roller. At this time, the discharging motor is driven to drive the dial shaft to rotate, thereby driving the dial rod to rotate. When the dial rod rotates, it will contact the two ends of the core wire, so that the core wire can be pushed out to realize the discharging of the core wire, so as to facilitate the molding and production of the next core wire, reduce the trouble of manual discharging, and improve production efficiency.

[0026] Reference Figure 1-5 A core wire elbow forming machine includes a workbench 90, a wire feeding assembly 70 is installed on the top of the workbench 90, and the wire feeding assembly 70 includes a third support seat 71 installed on the top of the workbench 90, a wire feeding seat 72 is installed on the top of the third support seat 71 in a horizontal sliding direction, and a wire feeding telescopic cylinder 73 is also installed on the top of the third support seat 71, and the output end of the wire feeding telescopic cylinder 73 is transmission-connected with the wire feeding seat 72, so that the wire feeding telescopic cylinder 73 can push the wire feeding seat 72 to slide. A side plate 74 is installed on the rear side of the wire feeding seat 72, and the side plate 74 is L-shaped. A clamping telescopic cylinder 75 is installed on the top of the side plate 74, and the clamping telescopic cylinder 75 is vertically inverted on the top of the side plate 74, so that the telescopic output end of the clamping telescopic cylinder 75 faces the top surface of the wire feeding seat 72, and a clamping block 76 is fixedly installed on the telescopic output end of the clamping telescopic cylinder 75. A wire feeding groove 77 is provided on the top surface of the wire feeding seat 72, and the two sides of the wire feeding groove 77 are inclined, so that the cross section of the wire feeding groove 77 is V-shaped. The two ends of the wire feeding groove 77 pass through the two sides of the wire feeding seat 72, and the length direction of the wire feeding groove 77 is parallel to the sliding direction of the wire feeding seat 72. A clamping groove 78 is also provided on the top surface of the wire feeding seat 72, and the clamping groove 78 is connected to the wire feeding groove 77, and the clamping groove 78 and the clamping block 76 can be adapted and fitted, and the depth of the clamping groove 78 is slightly smaller than the depth of the wire feeding groove 77. When the core wire is placed in the wire feeding groove 77, the clamping telescopic cylinder 75 is driven to push the clamping block 76 to embed into the clamping groove 78. At this time, the core wire can just be at the bottom of the wire feeding groove 77, and the bottom of the clamping block 76 can slightly press the core wire, which can clamp the core wire while preventing the clamping block 76 from crushing the core wire.
[0027] After the core wire is placed in the wire feeding groove 77, the clamping block 76 is driven to clamp the core wire by driving the clamping telescopic cylinder 75, and then the wire feeding telescopic cylinder 73 is driven to push the core wire to perform wire feeding movement.
[0028] A flattening assembly 10 and an elbow assembly 30 are installed on the top of the workbench 90. The flattening assembly 10 includes a first support seat 11 installed on the top surface of the workbench 90, a support block is installed on the top of the first support seat 11, a fixed pressure roller 12 is rotatably installed on the front side of the support block, a fixed roller motor 14 is installed on the rear side of the support block, and the fixed roller motor 14 is transmission-connected with the fixed pressure roller 12 so that the fixed roller motor 14 can drive the fixed pressure roller 12 to rotate. Side frames are installed on both sides of the support block, and the height of the side frames is higher than the height of the support block. A pressure block 13 is vertically slidably installed in the middle of the two side frames, and a dynamic pressure roller 15 is rotatably installed on the front side of the pressure block 13. A dynamic roller motor 16 is also installed on the rear side of the pressure block 13, and the output end of the dynamic roller motor 16 is transmission-connected with the dynamic pressure roller 15 so that the dynamic roller motor 16 can drive the dynamic pressure roller 15 to rotate. The rotation centerline of the dynamic pressure roller 15 and the rotation centerline of the fixed pressure roller 12 are on the same vertical plane, and the shortest gap formed between the dynamic pressure roller 15 and the outer peripheral side of the fixed pressure roller 12 is the first gap. The position of the first gap corresponds to the position of the wire feeding groove 77, and the sliding direction of the wire feeding seat 72 is perpendicular to the rotation centerline of the fixed pressure roller 12. When the core wire is clamped between the wire feeding seat 72 and the clamping block 76, when the wire feeding telescopic cylinder 73 is driven to push the core wire to move, one end of the core wire can be inserted into the first gap.
[0029] The first support seat 11 is also equipped with a first driving member 20, which includes a fixed block installed on the top of the two side frames, a cam 21 is rotatably installed on the front side of the fixed block, and a downward pressing motor 22 is installed on the rear side of the fixed block. The output end of the downward pressing motor 22 is connected to the cam 21 in a transmission manner, so that the downward pressing motor 22 can drive the cam 21 to rotate, and the outer peripheral side of the cam 21 presses against the top surface of the pressing block 13. A receiving groove is provided on the top of the support block, and an elastic member 23 is installed in the receiving groove. The elastic member 23 is a coil spring. When the coil spring is completely placed in the receiving groove, the top of the coil spring is higher than the opening of the receiving groove, so that the coil spring protrudes from the top surface of the support block. When the pressing block slides to the bottom and contacts the top surface of the support block, the coil spring is compressed. When the protruding side of the cam 21, i.e., the side with a larger radius, contacts the top surface of the pressing block 13, the pressing block 13 will overcome the elastic force of the coil spring and be pressed down to the lowest position, so that the width of the first gap becomes smaller. With the assistance of the opposite rotation of the fixed pressure roller 12 and the dynamic pressure roller 15, the core wire inserted into the first gap can be flattened. In other embodiments, the first driving member 20 can also be a downward-pressing telescopic cylinder installed on the first support seat 11, and the output end of the downward-pressing telescopic cylinder is connected to the pressing block 13, and the pressing block 13 and the dynamic pressure roller 15 are pushed closer to or away from the fixed pressure roller 12 by driving the downward-pressing telescopic cylinder.
[0030] A guide assembly 60 is installed on the side of the first support seat 11 close to the elbow assembly 30, and the guide assembly 60 includes a clamping cylinder 61 and a claw plate 62. The clamping cylinder 61 is installed on the side of the first support seat 11 close to the elbow assembly 30, and the two clamping output ends of the clamping cylinder 61 are vertically distributed. Two claw plates 62 are provided and respectively installed on the two output ends of the clamping cylinder 61. The two end surfaces of the two claw plates 62 are inclined outward on the side close to each other to form a pointed shape. A guide groove 63 is opened on the side close to the two claw plates 62. The length direction of the guide groove 63 is parallel to the wire feeding direction. The size of the slot formed by the two guide grooves 63 is slightly larger than the size of the core wire, so that the core wire can slide in the slot. The position of the slot formed by the two guide grooves 63 corresponds to the position of the first gap. After the core wire comes out of the first gap, it can enter the space between the two claw plates 62. Then, the clamping cylinder 61 is driven to make the core wire be in the slot formed by the two guide grooves 63. The slot can guide the transportation of the core wire and ensure the stability of the direction in which the core wire continues to be transported after being flattened.
[0031] The elbow assembly 30 includes a base 50 mounted on the top of the workbench 90, and a second support seat 31 is slidably mounted on the top of the base 50. The second support seat 31 is located on one side of the first support seat 11, and the sliding direction of the second support seat 31 is parallel to the conveying direction of the core wire, that is, it slides in the direction close to or away from the flattening assembly 10. A wire insertion telescopic cylinder 51 is installed on the top of the base 50, and the output end of the wire insertion telescopic cylinder 51 is transmission-connected to the second support seat 31, so that the wire insertion telescopic cylinder 51 can drive the second support seat 31 to slide.
[0032] A winding shaft 32 is rotatably mounted on the top of the second support seat 31, a synchronous wheel is mounted on one end of the winding shaft 32, a winding motor 33 is also mounted on the top of the second support seat 31, a synchronous wheel is mounted on the output end of the winding motor 33, and the two synchronous wheels are connected by a belt drive, so that the winding motor 33 can drive the winding shaft 32 to rotate. The rotation centerline of the winding shaft 32 is parallel to the rotation centerlines of the fixed pressure roller 12 and the dynamic pressure roller 15.
[0033] The winding shaft 32 is sleeved with a fixing ring 44, and a notch 45 is provided on one side of the fixing ring 44, so that the fixing ring 44 can be easily rotated or slid relative to the winding shaft 32 to adjust the position of the fixing ring 44 relative to the winding shaft 32. After the position of the fixing ring 44 is determined, a bolt 46 is installed at the end of the fixing ring 44 near the notch 45, and the head of the bolt 46 abuts against one of the end positions of the fixing ring 44 near the notch 45. The rod of the bolt 46 passes from one end of the fixing ring 44 near the notch 45 to the other end and is threadedly connected with the other end. Tightening the bolt 46 can reduce the notch 45, so that the fixing ring 44 clamps the winding shaft 32 and fixes the fixing ring 44 on the winding shaft 32. A sliding groove 47 is provided near the inner side wall of the fixing ring 44, and a clamping knife 34 is slidably installed in the sliding groove 47 along the axial direction of the winding shaft 32. The clamping knife 34 is located on one side of the winding shaft 32, and the clamping knife 34 is separated from the winding shaft 32 by a preset distance to form a second gap. The second gap corresponds to the position of the slot formed by the two guide grooves 63, that is, the position of the first gap is also set correspondingly to the position of the second gap, and the width direction of the first gap is parallel to the width direction of the second gap. After the core wire extends from the slots in the two claw plates 62, it can be inserted into the second gap.
[0034] A second driving member 40 is installed on the top of the second support seat 31. The second driving member 40 includes a push block 41. A plurality of guide rods are installed on one side of the push block 41. The plurality of guide rods are inserted and slidably arranged on the front side of the second support seat 31 along the axial direction of the winding shaft 32. A shaft push telescopic cylinder 42 is also installed on the top of the second support seat 31. A connecting plate is installed on the output end of the shaft push telescopic cylinder 42. The connecting plate is installed on the push block 41, so that the shaft push telescopic cylinder 42 can drive the push block 41 to slide. A connecting block 43 is rotatably installed in the middle of the push block 41 through a bearing. The winding shaft 32 is penetrated at the center of the connecting block 43. The connecting block 43 can slide relative to the winding shaft 32. The connecting block 43 is fixedly installed with the clamping knife 34. When the driving shaft push telescopic cylinder 42 drives the push block 41 to slide, it can drive the connecting block 43 and the clamping knife 34 to slide relative to the winding shaft 32.
[0035] After the core wire is sent out from the two claw discs 62, the wire insertion telescopic cylinder 51 is driven to drive the second support seat 31 to move, so that the winding shaft 32 can be closer to the position of the claw disc 62, so that the core wire can be more easily inserted into the second gap; then the shaft push telescopic cylinder 42 is driven to drive the clamping knife 34 to extend, so that the core wire is embedded in the second gap. Then, by synchronously conveying the core wire and driving the wire insertion telescopic cylinder 51, there is a certain operating space between the winding shaft 32 and the claw disc 62 to bend the core wire; finally, by driving the winding motor 33, the winding shaft 32 and the clamping knife 34 are driven to rotate together, and the flattened end of the core wire can be bent. During the bending process, the driving shaft push telescopic cylinder 42 pushes the clamping knife 34 to move slightly backward. The core wire can be driven to deviate a certain amount to prevent the part of the core wire that is bent from interfering with the part that is not bent, thereby affecting the quality of the elbow.
[0036] It should be noted that the elbow forming of the core wire is not limited to the above-mentioned operation mode, and the front and rear execution time and / or sequence of each driving member can also be appropriately adjusted to achieve a better forming effect.
[0037] In addition, a positioning telescopic cylinder 80 is installed on the side of the first support seat 11 close to the wire feeding seat 72, and a positioning plate 81 is installed at the output end of the positioning telescopic cylinder 80. The positioning plate 81 is L-shaped, and one end of the positioning plate 81 is vertical and the surface is perpendicular to the core wire conveying direction. The positioning plate 81 is located between the wire feeding seat 72 and the fixed pressure roller 12. When the core wire is placed in the wire feeding seat 72, one end of the core wire is abutted against the positioning plate 81, and the end of the core wire can be positioned. After the clamping block 76 clamps the core wire, the positioning telescopic cylinder 80 can be driven to remove the positioning plate 81 so that the positioning plate 81 does not affect the conveying of the core wire. A limited telescopic cylinder 82 is also installed on the front side of the first support seat 11. The telescopic direction of the limited telescopic cylinder 82 is parallel to the conveying direction of the core wire. The output end of the limited telescopic cylinder 82 faces the wire feeding seat 72 and is installed with a limited block 83. The limit block 83 can limit the conveying end position of the wire feeding seat 72, thereby ensuring the accuracy of the wire feeding position.
[0038] In addition, a discharging assembly 91 is installed on the top of the workbench 90. The discharging assembly 91 includes a fourth support seat 92 and a shifting shaft 93. The fourth support seat 92 is installed on the top of the workbench 90 in front of the first support seat 11 and the second support seat 31. Brackets are installed on both sides of the top of the fourth support seat 92. The two ends of the shifting shaft 93 are rotatably installed on the brackets on both sides. One of the brackets is installed with a discharging motor 94. The output end of the discharging motor 94 is connected to the shifting shaft 93 in a transmission manner, so that the discharging motor 94 can drive the shifting shaft 93 to rotate. A product box is placed in front of the two brackets. Both ends of the shifting shaft 93 are ring-arranged with a plurality of shifting rods 95, and the shifting rods 95 are arranged in an arc shape. The shifting rod 95 at one end is located on the side of the fixed pressure roller 12 close to the wire feeding seat 72, and the shifting rod 95 at the other end is located on the side of the claw plate 62 close to the winding shaft 32. After the core wire is flattened and the elbow is formed, the discharging motor 94 is driven to drive the lever 93 to rotate, thereby driving the lever 95 to pull out the formed core wire. After the core wire is pulled out, it can fall into the product box for storage and placement, so as to facilitate the flattening and elbow forming of the next core wire and improve production efficiency.
[0039] It should be noted that the first support seat 11 , the base 50 , the third support seat 71 and the fourth support seat 92 may be an integrally connected structure, or may be the top structure of the workbench 90 .
