Description

Technical Field

[0002] Threaded steel mesh actually refers to steel mesh, also known as welded steel mesh, steel welded mesh, steel welded mesh, steel welded mesh, etc. It is a mesh made of longitudinal and transverse steel bars arranged at a certain interval and at right angles to each other, and all intersections are welded together; the application of steel mesh also improves the quality of steel engineering because it can provide more evenly distributed force and better structural stability; this mesh is composed of steel bars of different diameters, usually between 4-14mm in diameter, and the intersections of the steel bars are firmly connected together through welding technology to form a solid grid structure; it can be seen that threaded steel mesh is mainly produced by The production and processing effect is achieved by positioning and arranging the steel bars vertically and horizontally and welding them. For example, the patent document with the prior art publication number CN211219405U provides a steel mesh positioning welding device, which is composed of a positioning mechanism using a sliding groove, a steel bar fixing piece and a plate body, and multiple groups of steel bar fixing pieces are arranged in the sliding groove. When in use, the required number of steel bar fixing pieces can be installed according to needs, and the distance between each steel bar fixing piece can be adjusted according to the size of the grid in the steel mesh.

[0070] The present application is further described in detail below in conjunction with the accompanying drawings.

[0071] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 8 The embodiment of the present application discloses a steel bar welding positioning device for the production and processing of threaded steel mesh, including a base 1, a square rod 11 is symmetrically arranged on the top of the base 1, a welding mechanism 2 is slidably arranged on the outer side of the square rod 11, the welding mechanism 2 includes a bearing plate 21 slidably arranged on the outer side of the square rod 11, a welding gun 22 that can move along the longitudinal and vertical directions is arranged on the outer side of the bearing plate 21, side plates 12 are arranged on both sides of the top of the base 1, and a longitudinal positioning mechanism 3 is arranged on the outer side of the side plate 12, and the longitudinal positioning mechanism 3 includes two groups of positioning mechanisms with fixed inner sides. The two groups of positioning seats A31 are respectively arranged on the outside of the side plate 12. A transverse positioning mechanism 4 is also arranged on the top of the base 1. The transverse positioning mechanism 4 includes two liftable supports 41. Chains C42 are arranged on the sides of the supports 41 that are close to each other. Positioning seats B43 for transversely conveying and positioning steel bars are evenly distributed on the outer peripheral side of the chain C42, and positioning grooves are opened on the inner side of the positioning seat B43. Driven by the chain C42, the positioning seat B43 synchronously drives the welding gun 22 to move transversely and position when conveying steel bars.

[0072] When arranging the transverse steel bars, the threaded steel bars are longitudinally positioned by the positioning seats A31 evenly distributed on the outside of the side plate 12 to ensure the accuracy of the arrangement of the lower steel bars; then the longitudinal steel bars are placed in the positioning grooves on the inner side of the positioning seats B43, and the positioning seats B43 are moved a specified distance under the drive of the chain C42, so that the steel bars carried by the positioning seats B43 can be moved to the welding position. At this time, the positioning seats B43 drive the bearing plate 21 to slide horizontally along the square rod 11, so that the bearing plate 21 drives the welding gun 22 to be located obliquely above the welding point, and then the steel bars are placed on the top of the lower steel bars under the descending action of the support 41. At this time, the upper steel bars are positioned at the welding position under the action of the positioning seats B43, and finally welded by the welding gun 22. The end is tilted and telescoped downward, so that the welding end is close to the welding point between the two vertically staggered steel bars to achieve the welding effect, and under the action of the longitudinal movement of the welding gun 22, the welding gun 22 can weld each longitudinal steel bar, and then under the action of the transverse positioning mechanism 4, the welding gun 22 can be automatically positioned in the transverse direction, so that the welding gun 22 can adapt to the welding of steel meshes of different specifications. After welding, the support 41 continues to descend to make the positioning seat B43 separate from the steel bar to ensure the continuous operation of the chain C42; the positioning grooves on the inner sides of the positioning seat A31 and the positioning seat B43 are both V-shaped grooves, which can adapt to threaded steel bars of different diameters, and two welding guns 22 are symmetrically arranged, located on both sides of the steel bar, for welding the welding points on both sides at the same time.

[0073] In order to ensure that the positioning seat B43 does not affect the continuous operation of the chain C42 after it is separated from the steel bar, refer to Figure 1 , Figure 2 , Figure 7 , Figure 8 , Fig. 9 The lateral positioning mechanism 4 also includes two groups of sprockets E46 for driving the chain C42 to run. The two groups of sprockets E46 are rotatably installed on the outside of the support 41, and the two corresponding sprockets E46 in the two groups are linked by a connecting shaft 47, and one sprocket E46 runs under the drive of the motor B44, and the motor B44 is fixedly installed on the outside of the support 41. The bottom of the two supports 41 is provided with a hydraulic push rod B45 for providing lifting power. The hydraulic push rod B45 is fixedly installed on the top of the base 1, and the outside of the support 41 is fixedly provided with a support plate 48 for supporting the top positioning seat B43. The support plate 48 is located within the inner circumference of the chain C42. The positioning seat B43 is rotatably provided on the outside of the chain C42 for rotating to one side to escape from the obstruction of the upper steel bars.

[0074] When the longitudinal steel bars are transported through the transverse positioning mechanism 4, the motor B44 is used to drive one of the sprockets E46 to rotate, so that the two groups of sprockets E46 respectively drive the two chains C42 to operate, thereby realizing the transport function of the positioning seat B43. At this time, the steel bars are lifted up and moved forward by the positioning seat B43. When the steel bars are placed on the top of the transverse steel bars in the lower layer and the positioning seat B43 is lowered and separated from the ends of the steel bars, the positioning seat B43 is rotated to make the lifting part away from the ends of the steel bars. At this time, the positioning seat B43 will not form contact with the ends of the steel bars when it is reset upward again under the drive of the support 41, thereby preventing the steel bars from affecting the lifting and lowering of the support 41 and the positioning seat B43 after welding, so that the positioning seat B43 can be repeatedly lifted and lowered to move multiple steel bars forward in sequence for positioning; wherein the control ends of the motor B44 and the hydraulic push rod B45 are electrically connected to the display controller 17 outside the base 1, and are used to control the motor B44 and the hydraulic push rod B45 to automatically operate according to the program input into the display controller 17.

[0075] In the above technical solution, in order to realize that the lifting portion of the positioning seat B43 can be rotated away from the end of the steel bar, refer to Figure 2 , Figure 7 , Figure 8 and Fig. 9 The positioning seat B43 includes a U-shaped part 431 fixedly installed on the outside of the chain C42, a shaft sleeve 432 is fixedly provided on one side of the end of the U-shaped part 431, a pin shaft 433 is rotatably provided on the inner side of the shaft sleeve 432, a rotating block 434 is fixedly provided on the outer side of the pin shaft 433, a supporting block 435 as a lifting part is fixedly provided on the outer side of the rotating block 434, and a positioning groove is provided on the inner side of the supporting block 435; one end of the rotating block 434 is fixedly connected to the pin shaft 433, and the other end can be rotated to the bottom of the end of the steel bar through the pin shaft 433, which is used to lift and support the steel bar, and a limit platform 438 for horizontally supporting the rotating block 434 is fixedly provided on the outer side of the shaft sleeve 432.

[0076] When the positioning seat B43 receives the load-bearing steel bar, the rotating block 434 is in a horizontal state under the support of the limit platform 438. At this time, the positioning groove on the inner side of the support block 435 is opened upward, so that the end of the steel bar can be placed on the inner side of the support block 435 for positioning. When the steel bar is welded, the positioning seat B43 is driven by the support 41 to move down as a whole and separate from the end of the steel bar. At this time, the supporting block 435 can be driven away from the end of the steel bar by rotating the rotating block 434, so that the positioning seat B43 as a whole does not contact the end of the steel bar in the vertical direction, so as to ensure that the positioning seat B43 can be repeatedly raised and lowered driven by the support 41.

[0077] Further, in order to facilitate the rotation of the positioning seat B43 away from the end of the steel bar and simplify the operation process, refer to Figure 2 , Figure 7 , Figure 8 and Fig. 9The positioning seat B43 also includes an extension plate 436 fixed on the outside of the support block 435. One side of the extension plate 436 rotates to the top of the U-shaped member 431 under the drive of the support block 435. At this time, the extension end of the extension plate 436 rotates to the side of the U-shaped member 431 away from the end of the steel bar. A counterweight block 437 is fixedly arranged at the extension end of the extension plate 436, and a limit plate 49 for limiting the support block 435 is fixedly arranged on the outside of the support 41.

[0078] Under the action of the extension plate 436, when the support block 435 moves downward and detaches from the end of the steel bar, the counterweight block 437 presses down the extended end of the extension plate 436, so that the extension plate 436 drives the support block 435 to rotate to the side away from the end of the steel bar, and rotates from a horizontal state to a vertical state, so that the effect of the support block 435 automatically rotating and detaching from the steel bar is achieved; and with the conveyance of the chain C42, when the positioning seat B43 moves to the bottom of the chain C42, the support block 435 automatically rotates and resets under the action of the counterweight block 437, and at this time, the support block 435 drives the rotation The movable block 434 is close to the outer side of the limit platform 438. When the support block 435 moves back to the top of the chain C42, the support block 435 receiving the steel bar is in an open upward state under the action of the limit plate 49. After the support block 435 drives the steel bar away from the limit plate 49, it always keeps in a supported state due to the pressure of the steel bar. Similarly, each support block 435 can automatically detach from the end of the steel bar after the steel bar is welded, and automatically reset with the drive of the chain C42. There is no need to rotate the support block 435 separately, making the operation more convenient.

[0079] Based on the above scheme, in order to realize that the positioning seat B43 can drive the steel bar and the welding gun 22 to move and position synchronously, refer to Figure 2 , Figure 3 , Figure 6 and Figure 7 The welding mechanism 2 also includes a push plate 26 symmetrically fixedly installed at the bottom of the supporting plate 21. A reinforcing plate 27 is fixedly arranged on the outside of the supporting plate 21 and the push plate 26. The reinforcing plate 27 is located on the side of the push plate 26 away from the positioning seat B43, and the push plate 26 is located on the outside of the support block 435, and at the same time does not contact the U-shaped piece 431 and the limit platform 438.

[0080] When the support block 435 carries and transports the steel bar under the pressure of the steel bar, the support block 435 will contact with the push plate 26 and push it forward, so that the support block 435 simultaneously drives the push plate 26 and the steel bar to be located at the welding position. At this time, the push plate 26 drives the welding gun 22 to be located above the welding position through the support plate 21, and when the support block 435 completes the positioning and disengages from the steel bar, it also disengages from the push plate 26, so that the push plate 26 cannot move temporarily, and waits for the next support block 435 to drive the steel bar to move to the next positioning point, and then drives the push plate 26 to move to the next positioning point again, and so on. Each time a steel bar is positioned, the welding gun 22 can be automatically positioned laterally, so that the welding gun 22 can be conveniently positioned before welding.

[0081] In order to facilitate the positioning of the horizontally arranged steel bars in the lower layer, refer to Figure 1 , Figure 4 and Figure 5 The longitudinal positioning mechanism 3 also includes two chains B32, and positioning seats A31 are evenly distributed on the outer peripheral sides of the two chains B32. Each chain B32 is driven by a sprocket B33 and a sprocket C34. The two sets of sprockets B33 and sprocket C34 are rotatably installed on the outer sides of the two side plates 12. A motor A37 is fixedly arranged on the outer side of one of the side plates 12. The motor A37 is linked with one of the sprockets B33. The two sprockets C34 are linked through a flower shaft 36. The flower shaft 36 is located between the two side plates 12, and the motor A37 is electrically connected to the display controller 17 on the outer side of the base 1.

[0082] When arranging the lower layer of steel bars, the steel bars can be loaded at the designated position without moving the steel bars to the positioning seat A31 at different positions. The positioning seat A31 at the loading position can move forward a certain distance driven by the chain B32 after receiving the steel bars. At this time, the distance that the chain B32 drives the positioning seat A31 to move is controlled by the motor A37, and the motor A37 is controlled by the display controller 17. Therefore, according to the required spacing of the steel bars, the motor A37 can be controlled to work automatically by inputting a program into the display controller 17, so that the positioning seat A31 can carry the steel bars and automatically position them.

[0083] Among them, in order to make the longitudinal positioning mechanism 3 adapt to the positioning work of steel bars of different lengths, one of the side plates 12 is slidably arranged on the top of the base 1 through a slide rail 13, and a hydraulic push rod A14 for driving the side plate 12 to slide is fixedly arranged on the top of the base 1, and the side plate 12 is slidably installed on the outside of the flower axis 36, and the two ends of the flower axis 36 are rotatably installed with the base 1 and the other side plate 12 respectively, and sprockets D35 are rotatably arranged on the outside of the two side plates 12, one of the sprockets D35 is coaxially fixedly installed with the sprocket D35, and the other sprocket D35 slides along the axial direction of the flower axis 36 under the drive of the side plate 12, and the two sprockets D35 are linked with the corresponding sprockets C34; when the motor A37 is running, it can drive the two chains B32 to run synchronously, and at the same time, when the hydraulic push rod A14 drives the side plate 12 to drive the longitudinal positioning mechanism 3 to adjust the support length, the side plate 12 drives the corresponding sprocket D35 to slide along the flower axis 36, and the linkage between the two chains B32 can always be maintained.

[0084] In order to facilitate the positioning of the welding gun 22 during longitudinal movement welding, refer to Figure 4 , Figure 5 , Figure 6 and Figure 7 , the two square rods 11 are rotatably connected to the top bracket of the base 1, a pulley A16 is fixedly arranged on the outer side of one of the square rods 11, rod sleeves 23 are axially slidably installed on the outer sides of the two square rods 11, and the rod sleeves 23 are rotatably arranged on the inner side of the bearing plate 21, and a gear A24 is coaxially fixedly arranged on the outer side of one of the rod sleeves 23, and the gear A24 is linked with the translation assembly 25 on the outer side of the bearing plate 21;

[0085] The motor A37 is fixedly mounted on the outside of the side plate 12 via a fixing seat 15, a sprocket B33 is movably mounted on the outside of the driving end of the motor A37 via a one-way bearing, and a pulley B38 is coaxially fixedly arranged on the outside of the driving end of the motor A37, and the pulleys B38 are linked to each other via the pulley A16.

[0086] When the driving end of motor A37 drives sprocket B33 to rotate through the one-way bearing, the driving end of motor A37 synchronously drives pulley B38 to rotate, so that pulley B38 drives pulley A16 to rotate, and pulley A16 drives translation assembly 25 to operate through square rod 11 and gear A24, so that translation assembly 25 drives welding gun 22 to move back and forth horizontally. At this time, the movement of welding gun 22 does not affect the positioning work of longitudinal positioning mechanism 3 on steel bars; after the lower steel bars are positioned and arranged, motor A37 is controlled to run in reverse through display controller 17, so that the driving end of motor A37 drives the inner ring of the one-way bearing to reverse, and then cannot drive sprocket B33 to rotate, so that the positioned steel bars remain stable. At this time, motor A37 drives pulley B38 to reverse alone, so that pulley A16 drives translation assembly 25 to run in reverse, and then translation assembly 25 drives welding gun 22 to move longitudinally, and motor A37 automatically controls the start and stop of welding gun 22 according to the program input into display controller 17.

[0087] When the welding gun 22 is positioned horizontally, in order to realize the translation assembly 25 driving the welding gun 22 to perform positioning welding, refer to Figure 1 , Figure 3 , Figure 6 and Figure 7 The welding mechanism 2 also includes a translation assembly 25 arranged on the outside of the bearing plate 21. The translation assembly 25 includes two sprockets A251 rotating on the outside of the bearing plate 21, wherein a gear B253 is coaxially fixedly connected to the outside of one of the sprockets A251, and the gear B253 is meshed with the gear A24. The two sprockets A251 are linked by a chain A252, and a sliding pin 254 is fixedly arranged on the outside of the chain A252. The sliding pin 254 is slidably arranged on the inside of a slider 255. A vertical sliding hole is opened on the inside of the slider 255, and the slider 255 is slidably installed on the outside of a sliding rod 258. The sliding rod 258 is fixed on the outside of the bearing plate 21 parallel to the chain A252. An electric push rod 256 is fixedly arranged at the bottom of the slider 255, and a welding gun 22 is installed on the telescopic end of the electric push rod 256 through a connecting piece 257.

[0088] When performing longitudinal welding, based on the lateral positioning of the push plate 26, the chain A252 drives the sliding pin 254 to move horizontally, so that the sliding pin 254 pushes the slider 255 to move longitudinally along the slide rod 258, thereby driving the welding gun 22 to move longitudinally, and each time it moves above a welding point, the electric push rod 256 pushes the welding gun 22 to approach the welding point by a certain distance, and finally the welding end of the welding gun 22 is tilted downward and retracted to approach the welding point, so that the welding gun 22 can realize the longitudinal welding function. At this time, the operation process of the translation assembly 25 is controlled by the motor A37, and the motor A37 runs in reverse according to the input positioning program of the display controller 17. There is no need to position and control the welding gun 22 separately, so that the longitudinal movement and positioning of the welding gun 22 is more convenient. The welding gun 22 can adjust the inclination angle on the outside of the connecting piece 257 to adapt to the welding of steel bars of different thicknesses.

[0089] In order to facilitate the feeding of the steel bars to the longitudinal positioning mechanism 3 and the transverse positioning mechanism 4, refer to Figure 1 , Figure 2 , Fig.10 and Fig.11, and also includes a feeding mechanism 5, which is arranged on the outside of the base 1. The feeding mechanism 5 includes a bottom plate 51 and a hydraulic support 52 located on the top of the bottom plate 51, a hydraulic support arm 53 is fixedly arranged on the top of the hydraulic support arm 52, a positioning plate 55 is fixedly arranged at the bottom of the telescopic end of the hydraulic support arm 53 through an end seat 54, the positioning plate 55 and the inner side of the positioning groove match each other, a mechanical claw A56 is arranged on the outside of the telescopic end of the hydraulic support arm 53 near the positioning plate 55, and a mechanical claw B57 is arranged on the outer shell of the hydraulic support arm 53, a straightening mechanism 58 is arranged at the bottom of the hydraulic support arm 53, a cutting knife 59 is arranged on the outside of the hydraulic support arm 53, and a hydraulic push rod C510 for driving the cutting knife 59 to move is fixedly arranged on the top of the hydraulic support arm 53.

[0090] During loading, the steel bar is straightened by the straightening mechanism 58 at the bottom of the hydraulic support arm 53. When the end of the steel bar reaches the outside of the positioning plate 55, the bottom support of the steel bar is closed by the mechanical claws A56 and B57, and the positioning plate 55 is pushed forward by the telescopic end of the hydraulic support arm 53. At the same time, the straightening mechanism 58 conveys the straightened steel bar forward, so that the steel bar can move forward while being straightened. When the positioning plate 55 moves forward a certain distance and is aligned with the positioning groove directly below, the cutting knife 59 is pushed by the hydraulic push rod C510 to cut the steel bar. At the same time, the straightening mechanism 58 has a clamping effect on the steel bars, which can ensure stable cutting of the steel bars. Finally, under the action of the hydraulic support 52, the hydraulic support arm 53 drives the steel bars to move downward. When the positioning plate 55 is located on the inner side of the positioning groove, the support of the mechanical claws A56 and B57 for the steel bars is released, so that the steel bars automatically fall into the positioning grooves in the longitudinal positioning mechanism 3 and the transverse positioning mechanism 4, thereby realizing accurate loading of the steel bars. The straightening principle of the straightening mechanism 58 for the steel bars and the operating principle of the mechanical claws A56 and B57 are both existing technologies and will not be repeated here.

[0091] In order to enable the feeding mechanism 5 to feed the longitudinal positioning mechanism 3 and the transverse positioning mechanism 4 respectively, refer to Figure 4 , Fig.10 and Fig.11 A truncated table 18 is fixedly provided at one corner of the top of the base 1, and a bottom plate 51 is slidably provided on the outside of the truncated table 18 through a sliding sleeve 511. A rotating plate 512 is fixedly provided at the bottom of the bottom plate 51, and one end of the rotating plate 512 rotates even to the inside of the base 1. A motor C513 for driving the rotating plate 512 to rotate is fixedly provided on the top of the base 1. Hydraulic legs 514 are symmetrically fixedly provided at the bottom of the bottom plate 51, and a pad 515 is fixedly provided at the telescopic end of the bottom of the hydraulic legs 514.

[0092] By rotating the bottom plate 51 and installing it on the outside of the truncated table 18, the center of the truncated table 18 is located at the intersection of the longitudinal positioning mechanism 3 and the loading position of the transverse positioning mechanism 4. When the longitudinal positioning mechanism 3 completes the steel bar arrangement, the motor C513 drives the rotating plate 512 to drive the bottom plate 51 to rotate, so that the bottom plate 51 drives the hydraulic support arm 53 to rotate 90° to reach the loading position of the transverse positioning mechanism 4, and then the hydraulic support leg 514 pushes the pad 515 to move downward to support the bottom plate 51, thereby achieving two steel bar arrangements through one loading mechanism 5.

[0093] In summary, when the steel bar welding positioning device for the production and processing of threaded steel mesh disclosed in the embodiment of the present application is used, the feeding mechanism 5 is rotated to the feeding position of the longitudinal positioning mechanism 3, so that the feeding mechanism 5 straightens the steel bar through the straightening mechanism 58 and transports it forward. When the end of the steel bar reaches the outside of the positioning plate 55, the bottom support of the steel bar is closed by the mechanical claw A56 and the mechanical claw B57, and the positioning plate 55 is pushed forward by the telescopic end of the hydraulic support arm 53. At the same time, the straightening mechanism 58 transports the straightened steel bar forward, so that the steel bar can be straightened and moved forward. When the positioning plate 55 moves forward a certain distance and is aligned with the positioning groove directly below, the cutting knife 59 is pushed by the hydraulic push rod C510. For steel bar cutting, the straightening mechanism 58 has a clamping effect on the steel bar, which can ensure stable cutting of the steel bar. Finally, under the action of the hydraulic support 52, the hydraulic arm 53 drives the steel bar to move downward. When the positioning plate 55 is located inside the positioning groove, the support of the mechanical claw A56 and the mechanical claw B57 on the steel bar is released, so that the steel bar automatically falls into the positioning groove inside the positioning seat A31, realizing accurate feeding of the steel bar. Then the display controller 17 controls the motor A37 to run, so that the motor A37 can drive the two chains B32 to run synchronously when running, and then drive the positioning seat A31 and the steel bar to move horizontally through the chain B32. Repeating this process, multiple positioning seats A31 can position and arrange the steel bars, replacing the traditional manual operation.

[0094] When the longitudinal positioning mechanism 3 has completed the arrangement of the lower layer of steel bars, the motor C513 drives the rotating plate 512 to drive the bottom plate 51 to rotate, so that the bottom plate 51 drives the hydraulic support arm 53 to rotate 90° to reach the loading position of the transverse positioning mechanism 4, and then the hydraulic support leg 514 pushes the pad 515 to move downward to support the bottom plate 51; thereafter, the steel bars are straightened and loaded again through the loading mechanism 5, so that the longitudinal steel bars are automatically placed in the positioning groove on the inner side of the positioning seat B43. At this time, the support block 435 in the positioning seat B43 supports the steel bars, and the support block 435 located at the loading position opens upward under the action of the limit plate 49 so that During steel bar loading, the support block 435 drives the steel bar away from the limiting plate 49, and the support block 435 is always held up due to the pressure of the steel bar, so that the steel bar can be driven to move forward a certain distance, thereby achieving accurate horizontal positioning. At the same time, the support block 435 will contact the push plate 26 and push it forward, so that the support block 435 drives the push plate 26 and the steel bar to be located at the welding position at the same time. At this time, the push plate 26 drives the welding gun 22 to be located above the welding position through the bearing plate 21, and then the support 41 and the positioning seat B43 are moved downward as a whole under the action of the hydraulic push rod B45, so that the positioning seat B43 places the steel bar on the top of the lower steel bar;

[0095] During welding, the welding gun 22 is driven by the positioning seat B43 to be located at the first welding position of each longitudinal steel bar. At this time, the welding gun 22 is pushed by the electric push rod 256 to approach the welding point by a certain distance. Finally, the welding end of the welding gun 22 is tilted downward and retracted to approach the welding point, so that the welding gun 22 can achieve the longitudinal welding function; then the display controller 17 controls the motor A37 to run in the reverse direction, so that the driving end of the motor A37 drives the inner ring of the one-way bearing to reverse, and then cannot drive the sprocket B33 to rotate, so that the positioned steel bars remain stable. At this time, the motor A37 drives the pulley B38 to reverse alone, and the pulley B38 drives the square rod 11 to rotate through the pulley A16, so that the square rod 11 is driven by the gear A24 The translation assembly 25 is running, and one of the sprockets A251 in the translation assembly 25 rotates under the cooperation of the gear A24 and the gear B253, thereby driving the chain A252 to drive and run, and the chain A252 drives the sliding pin 254 to move horizontally, so that the sliding pin 254 pushes the slider 255 to move longitudinally along the slide bar 258, thereby driving the welding gun 22 to move longitudinally, and welding is performed in sequence each time it moves to the top of a welding point. At this time, the operation process of the translation assembly 25 is controlled by the motor A37, and the motor A37 runs in the reverse direction according to the input positioning program of the display controller 17, and there is no need to separately position and control the welding gun 22, so that the longitudinal movement and positioning of the welding gun 22 is more convenient;

[0096] After each longitudinal steel bar is welded, the hydraulic push rod B45 drives the support 41 to move downward, so that the positioning seat B43 is separated from the end of the steel bar to ensure the continuous operation of the chain C42, and the positioning seat B43 loses the pressure after being separated from the steel bar. At this time, the counterweight block 437 presses down the extension end of the extension plate 436, so that the extension plate 436 drives the support block 435 to rotate to the side away from the end of the steel bar, and rotates from the horizontal state to the vertical state, so that the support block 435 automatically rotates and separates from the steel bar; and with the conveyance of the chain C42, when the positioning seat B43 moves to the chain C4 2, the support block 435 automatically rotates and resets under the action of the counterweight block 437. At this time, the support block 435 drives the rotating block 434 to be close to the outer side of the limiting platform 438. When the support block 435 moves to the top of the chain C42 again, the support block 435 receiving the steel bar is in an upward opening state under the action of the limiting plate 49, so as to receive the next steel bar, and the support block 435 that does not receive the bearing steel bar will automatically rotate to the side away from the end of the steel bar, so that each time the steel bar is positioned, the influence between the positioning seat B43 and the welded steel bar will be automatically released.
