Description

Technical Field

[0001] The invention relates to the technical field of building material welding, in particular to a full-automatic multi-spot mesh welding machine based on a rolling positioning structure. Background Art

[0002] The main function of the steel mesh cage is to enhance the bearing capacity of the pile. The main reinforcement can improve the compressive strength of the pile and effectively transfer the upper structure load to the bearing layer at the bottom of the pile. It can also enhance the pull-out resistance of the pile, improve the seismic performance of the pile and enhance the integrity of the pile to prevent the concrete from breaking and falling off. In addition, the steel mesh cage can control the deformation of the pile, reduce the settlement and horizontal displacement of the pile, ensure that the pile remains stable under various stress conditions, and provide reliable foundation support for structures such as buildings.

[0003] The Chinese patent with application number 2020204729543 is specifically a pile reinforcement cage welding auxiliary device, which realizes the synchronous and flexible fixation between the reinforcement ring and the positioning seat through the cooperation of a number of positioning columns, and is used to flexibly adjust and fix the position of the metal hook for placing the longitudinal reinforcement;

[0004] However, the above patent content only has the function of fixing the longitudinal reinforcement. In the actual operation process, there is a lack of automatic feeding mechanism for long steel bars (i.e. longitudinal bars). There is also a lack of mechanism to correct the positions of the two ends of the long steel bars, resulting in inconsistent lengths of the welded longitudinal bars. During the welding process, frequent intervention is required to adjust the position of the steel bars to achieve the switching of the welding position, which not only increases the complexity of the process, but may also introduce operational errors. It does not have the ability to operate continuously, and the consistency of welding quality cannot be guaranteed. These limitations jointly limit its practical application in large-scale, high-efficiency production.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Embodiment 1: Figure 1-Figure 10As shown, the fully automatic multi-point mesh welding machine based on the rolling positioning structure includes a bottom plate 1, two bases 3 and two guide rails 4 are arranged on the top of the bottom plate 1, an electric sliding plate 301 is slidably connected in the base 3, and an electric sliding seat 401 is slidably connected in the guide rail 4, as shown in FIG. Figure 2 As shown, the electric sliding seat 401 realizes reciprocating sliding in the guide rail 4 through the synchronous cooperation of the external servo motor and the reciprocating screw rod, the top of the electric sliding plate 301 is fixedly connected with a bearing frame 5, the inner side of the bearing frame 5 is provided with a circular groove, the circular groove is movably connected with a turntable 6 through a bearing, and the outer side of the turntable 6 is provided with a material support assembly;

[0035] A guide plate 2 is symmetrically fixedly installed on one side of the top of the bottom plate 1, and a guide groove 31 is opened on the side wall of the guide plate 2. A slide plate 32 is arranged between the two guide plates 2. A plurality of vertical rods 33 are fixedly connected to the top of the slide plate 32. A support plate 34 is arranged on the top of the slide plate 32. A sliding sleeve 30 is fixedly connected to the bottom of the support plate 34. The vertical rod 33 is slidably connected to the inside of the sliding sleeve 30. Both sides of the support plate 34 are fixedly connected with protrusions, which are slidably connected in the guide groove 31. A plurality of linear rails are fixedly installed on the top of the bottom plate 1. A guide block is fixedly connected to the bottom of the slide plate 32, and the guide block is slidably connected in the linear rail.

[0036] like Figure 7 As shown, three linear rails are arranged on the top of the base plate 1, a reciprocating screw is arranged in the middle linear rail and driven by an external servo motor, and the guide block is threadedly connected to the reciprocating screw, and the corresponding servo motor drives the reciprocating screw to rotate, so that the guide block drives the top fixed moving connection with the slide plate 32 to slide back and forth. Since it is a conventional driving technology, it will not be described in detail here.

[0037] The two sides of the top of the support plate 34 are fixedly installed with clamping components, which are used to clamp the long strip of metal. The clamping components are composed of a fixed arc plate 341 and a rotating arc plate 342. The fixed arc plate 341 is fixed to the top of the support plate 34, and the rotating arc plate 342 is rotatably connected to the end of the fixed arc plate 341. A torsion spring is provided at the rotating connection between the rotating arc plate 342 and the fixed arc plate 341. The base 3 is symmetrically arranged on the top of the bottom plate 1, and the guide rail 4 is symmetrically arranged on the top of the bottom plate 1. The rotating arc plate 342 can be deflected and reset relative to the fixed arc plate 341, so as to facilitate continuous feeding of the long strip of metal.

[0038] The top of the base plate 1 is fixedly connected to a frame 20, and a plurality of electric push cylinders 21 and fans are fixedly installed at the bottom of the frame 20. The bottom end of the electric push cylinder 21 is fixedly connected to an electric clamp 22. The electric clamp 22 is an existing mechanism, and its function is to clamp the annular metal. An arc groove 221 is provided on the inner side of the electric clamp 22, and the annular metal slides in the arc groove 221 to realize the rotation of the annular metal.

[0039] When setting up specifically, firstly, a plurality of metal rings are placed in the electric clamp 22, the electric clamp 22 clamps and fixes the metal rings, and uses the electric push cylinder 21 to drive the metal rings to be lifted and lowered synchronously, so that the metal rings are lifted and lowered to the specified position, which is convenient for subsequent welding of the long steel bars and the annular metal. The first long metal strip is placed in the clamping assembly, and the long metal strip is stabilized and placed horizontally under the action of the fixed arc plate 341, the rotating arc plate 342 and the torsion spring. Then, the reciprocating screw rod, the guide block and the servo motor arranged inside and outside the linear track cooperate with each other to drive the slide plate 32 to slide horizontally, and at the same time, the support plate 34 drives the protrusions fixedly connected on both sides to slide in the guide groove 31;

[0040] The shape of the guide groove 31 is as follows: Figure 8 As shown, when the protrusion moves from the low position to the high position of the guide groove 31, the support plate 34 at this time drives the metal strip to rise synchronously through the clamping assembly on the top. The clamping assembly is arranged at both ends of the top of the support plate 34 to avoid interfering with the normal position welding of the long metal strip and the ring metal. When the support plate 34 rises from the low position to the high position and moves horizontally a short distance under the action of the protrusion and the guide groove 31, the support plate 34 drives the long metal strip to move horizontally until it contacts the bottom of the ring metal.

[0041] Embodiment 2: The material supporting assembly includes multiple groups of limit sleeves 701 and multiple groups of limit rods 702. The outer side of the turntable 6 is provided with installation grooves in a circular array. The limit sleeves 701 are fixedly installed in the installation grooves. The limit rods 702 are slidably connected in the limit sleeves 701. The end of the limit rod 702 is fixedly connected with a clamping sleeve 703. The end of the limit rod 702 away from the clamping sleeve 703 is fixedly connected with a clamping plate 704. A through groove 18 is provided at one end of the clamping plate 704. A linkage block 705 is provided on the other side of the turntable 6. The side wall of the linkage block 705 is provided with movable grooves 15 in a circular array. The guide rod 16 is fixedly connected in the movable groove 15. The clamping plate 704 is slidably connected to the guide rod 16 through the through groove 18.

[0042] The side wall of the supporting frame 5 is fixedly connected with a cover shell 8, and the inside of the cover shell 8 is fixedly installed with a motor 9, an electric push rod 10 and an electric push rod 2 11, the electric push rod 10 cooperates with the clamping plate 704, and the side wall of the turntable 6 is fixedly connected with multiple groups of support rods. The side wall of the linkage circular block 705 is provided with support grooves corresponding to the number of support rods, and the support rods are slidably connected in the support grooves to further improve the stability of the linkage circular block 705. A rotating groove is provided at the center of the other side wall of the linkage circular block 705, and the output end of the electric push rod 2 11 is fixedly connected with a push block 12, and the push block 12 is slidably connected in the rotating groove.

[0043] In the specific setting, when the long metal strip moves to the bottom of the annular metal and contacts it under the cooperation of the support plate 34 and the clamping assembly, the electric push rod 10 fixedly connected to the inner wall of the cover shell 8 is started, and the electric push rod 10 first contacts the clamping plate 704 and pushes the clamping plate 704 to move in the direction of the movable groove 15. The clamping plate 704 slides along the guide rod 16 using the through groove 18, and the clamping plate 704 drives the limiting rod 702 to slide in the limiting sleeve 701, and the limiting rod 702 drives the clamping sleeve 703 to move toward the end of the long metal strip;

[0044] Until the clamping sleeves 703 on both sides of the long metal strip are installed on the ends of the long metal strip. The clamping sleeves 703 are installed on both ends of the long metal strip. On the one hand, they can fix the placement position of the long metal strip so that it is always in contact with the bottom of the annular metal. On the other hand, they can calibrate the placement position of the long metal strip to ensure the correct welding position of the long metal strip and the annular metal.

[0045] A plurality of slide rails 23 are fixedly mounted on the top of the bottom plate 1, and a slider is slidably connected to the inner side of the slide rails 23. Figure 5 As shown, the inner and outer sides of the slide rail 23 are respectively provided with a reciprocating screw and a servo motor. The servo motor drives the reciprocating screw to rotate, thereby driving the slider to slide along the slide rail 23. During the sliding process, the slider drives the sleeve 242 at the top thereof to move synchronously, as shown in FIG. Fig. 9 As shown, multiple groups of slide rails 23 are arranged at an angle on the top of the bottom plate 1, so that the corresponding two electrode blocks 29 can contact and weld the long metal strips and the ring metal from the top and the bottom.

[0046] The top of the slider is fixedly connected with a sleeve 242, and an electric lifting frame 241 is slidably connected inside the sleeve 242. A pad 26 is fixedly connected to the top of the electric lifting frame 241, and a frame 25 is fixedly connected to the side wall of the electric lifting frame 241. The electric lifting frame 241 is a prior art, and its function is to automatically lift and lower inside the sleeve 242. Since it is a conventional driving technology, it will not be described in detail here.

[0047] A pressure plate frame 27 is slidably connected in a cylinder on one side of the top of the frame 25, a hydraulic push rod 28 is fixedly installed on one side of the bottom of the frame 25, the output end of the hydraulic push rod 28 is fixedly connected to the bottom end of the pressure plate frame 27, an electrode block 29 is fixedly installed on one side adjacent to the pressure plate frame 27 and the pad 26, and the electrode block 29 is connected to an external power supply mechanism.

[0048] When the long metal strip and the ring metal are placed in the correct position, the reciprocating screw in the slide rail 23 drives the sleeve 242 to move horizontally through the slider until the sleeve 242 moves to the lower part close to the welding position of the long metal strip and the ring metal. At this time, the electric lifting frame 241 is lifted and lowered in the sleeve 242 until the electrode block 29 located on the top of the pad 26 contacts the long metal strip, and the hydraulic push rod 28 drives the platen frame 27 to descend until the electrode block 29 at the bottom of one side of the platen frame 27 contacts the inner circular side wall of the ring metal, and the external power supply mechanism supplies power to the electrode block 29.

[0049] The principle of resistance welding is to assemble the long metal strips and ring metal to be welded into lap joints and place them between two electrode blocks 29, and apply current through an external power supply mechanism. Due to the resistance at the contact point of the weldment, a large amount of resistance heat is generated when the current passes through, causing the metal at the contact point to partially melt or plastically deform. At the same time, under the action of pressure, the weldment is forced to come into close contact to form a firm welded joint. The heat generation is based on Joule's heat law, and the quality and performance of the welded joint are guaranteed by controlling parameters such as current, power-on time and pressure.

[0050] During the process of resistance welding of the long metal strip and the ring metal by the electrode block 29 , the fan located at the bottom of the frame 20 continuously and appropriately cools the long metal strip and the ring metal.

[0051] Embodiment three: The circumferential side wall of the turntable 6 is fixedly connected with an annular rack 13, the output end of the motor 9 is fixedly connected with a linkage gear 14 meshing with the annular rack 13, and the interior of the electric sliding seat 401 is slidably connected with an electric lifting plate 17. It should be noted here that the electric lifting plate 17 is an existing mechanism, and its function is to perform adaptive lifting activities in the groove opened on the top of the electric sliding seat 401, and at the same time drive the arc support plate 19 to automatically lift and lower, and the top of the electric lifting plate 17 is fixedly installed with an arc support plate 19.

[0052] When the first long metal strip is successfully welded to the annular metal, the motor 9 fixed inside the housing 8 drives the linkage gear 14 to rotate, and the turntable 6 rotates under the meshing transmission of the linkage gear 14 and the annular rack 13. The turntable 6 drives the clamping sleeve 703 to rotate through the cooperation of the limiting sleeve 701 and the limiting rod 702, and the clamping sleeve 703 drives the long metal strip to deflect. Since the number of long metal strips welded on the outside of the annular metal does not reach the specified number, the annular metal can still slide in the arc groove 221 on the inner side of the electric clamp 22 at this time;

[0053] The process of welding the second and last long metal strips is as follows: after the first long metal strip is welded, the driving turntable 6 drives the welded long metal strip to deflect, so as to facilitate the subsequent long metal strips to be fed and contact with the bottom of the ring metal, and the subsequent long metal strips are continuously welded according to the method of welding the first long metal strip, until the number of long metal strips welded on the outside of the ring metal reaches the specified number, and then the electric clamp 22 releases the clamping of the ring metal and moves upward, and the electric lifting plate 17 drives the arc support plate 19 to rise and support the welded finished product;

[0054] It needs to be explained here that the output end of the electric push rod 11 is fixedly connected to the push block 12. When the turntable 6 rotates, the turntable 6 rotates relative to the push block 12, and there is no interference in the movement trajectory. Therefore, the electric push rod 11 fixed on the inner side of the cover 8 is started again. The electric push rod 11 pulls the linkage round block 705 through the push block 12. The linkage round block 705 moves stably by the cooperation of the support rod and the support groove. During the movement, the linkage round block 705 pulls the clamping plate 704 and then pulls the clamping sleeve 703 out of the end of the long metal strip, that is, the clamping of the long metal strip is released, and then the electric sliding seat 401 is used to move the finished product out from the bottom of the frame 20, thereby realizing automatic unloading of the finished product.

[0055] In summary, the positions of multiple ring-shaped metals are pre-fixed, and with the cooperation of the clamping assembly and the supporting assembly, the long strips of metal are continuously loaded, positioned and fixed, and then the electrode block 29 is used to perform a multi-point rolling, efficient and high-precision welding process.

[0056] The preferred embodiments of the present invention disclosed above are only used to help explain the present invention. The preferred embodiments do not describe all the details in detail, nor do they limit the invention to only specific implementation methods. Obviously, many modifications and changes can be made according to the content of this specification. This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the present invention, so that those skilled in the art can understand and use the present invention well.
