Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel cage welding, and in particular to a correction device for a steel cage rolling welding machine. Background Technology
[0002] A rebar cage welding machine is a specialized piece of equipment used for automated welding of rebar cages. It is widely used in engineering fields such as bridge pile foundations, building foundations, and tunnel support. It forms cylindrical or irregularly shaped rebar cages by resistance welding or arc welding of longitudinal main bars and spiral stirrups. In actual operation, the rebar cage is prone to longitudinal and lateral displacement due to mechanical vibration or material deformation, resulting in welding misalignment and poor coaxiality of the cage body. It is necessary to perform correction operations. Existing correction devices often use a one-way adjustment mechanism, which uses a single hydraulic cylinder or screw to drive the contact wheel for lateral compensation. However, it cannot achieve synchronous longitudinal dynamic adjustment, resulting in limited correction effect.
[0003] To address the above problems, a correction device for a steel cage welding machine has been developed. Utility Model Content
[0004] To overcome the shortcomings of existing correction devices that often use a unidirectional adjustment mechanism to drive the contact wheel for lateral compensation through a single hydraulic cylinder or screw, but cannot simultaneously achieve longitudinal dynamic adjustment, resulting in limited correction effect, this utility model provides a correction device for a rebar cage welding machine.
[0005] The technical solution of this utility model is as follows: a correction device for a rebar cage welding machine, comprising a mounting base, an electric push rod mounted on the upper right side of the mounting base, a push plate connected to the telescopic end of the electric push rod, a limiting frame connected to the upper middle part of the mounting base, a first sliding member slidably connected to the left side of the limiting frame, a second sliding member slidably connected to the right side of the limiting frame, a first connecting rod rotatably connected to the first sliding member, a second connecting rod rotatably connected to the second sliding member, a first rotating rod rotatably connected to the upper left side of the mounting base, the first rotating rod being rotatably connected to the second connecting rod, a second rotating rod rotatably connected to the upper left side of the mounting base, the second rotating rod being rotatably connected to the first connecting rod, a first contact wheel rotatably connected to the first rotating rod, a second contact wheel rotatably connected to the second rotating rod, and a correction mechanism provided on the mounting base.
[0006] Preferably, the correction mechanism includes a first drive motor, which is mounted on the upper side of the middle portion of the mounting base. A first lead screw is connected to the output shaft of the first drive motor, and the first lead screw is threadedly connected to the first sliding member. A second drive motor is also mounted on the upper side of the middle portion of the mounting base, and a second lead screw is connected to the output shaft of the second drive motor, and the second lead screw is threadedly connected to the second sliding member.
[0007] Preferably, it also includes a contact mechanism, which includes connecting rods. Several connecting rods are connected to both the front and rear sides of the push plate, and two rotating rollers are rotatably connected to each connecting rod.
[0008] Preferably, the mounting base is provided with a triangular rib for reinforcement.
[0009] Preferably, the mounting base has 6 mounting holes.
[0010] Preferably, the height of the first contact wheel is higher than that of the second contact wheel.
[0011] By adopting the above technical solutions, the beneficial effects of this utility model are as follows:
[0012] 1. This utility model uses a correction mechanism, in which the first drive motor and the second drive motor respectively control the first sliding member, the second sliding member, the first lead screw, and the second lead screw to transmit power, so that the rotating rod drives the high and low first contact wheel and the second contact wheel to form a misaligned force application point, dynamically sensing and accurately correcting the radial offset of the steel cage. At the same time, the electric push rod drives the push plate to move laterally, realizing bidirectional dynamic correction in both longitudinal and lateral directions, effectively ensuring the coaxiality and welding accuracy of the steel cage, and reducing the scrap rate.
[0013] 2. This utility model uses a contact mechanism and rotating rollers to convert sliding friction into rolling friction, which reduces the contact resistance between the steel cage and the push plate during the lateral correction process, reduces scratches on the material surface, avoids wear and deformation of the push plate due to long-term friction, and extends the service life of the device.

Detailed Implementation
[0020] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection and application of the present invention.
[0021] Example 1
[0022] A rebar cage welding machine correction device, such as Figure 1 and Figure 2 As shown, the device includes a mounting base 1 with a triangular rib for reinforcement. The mounting base 1 has six mounting holes. An electric push rod 3 is mounted on the upper right side of the mounting base 1. A push plate 4 is connected to the telescopic end of the electric push rod 3. A limit frame 5 is connected to the upper middle part of the mounting base 1. A first sliding member 6 is slidably connected to the left side of the limit frame 5, and a second sliding member 14 is slidably connected to the right side of the limit frame 5. A first connecting rod 2 is rotatably connected to the first sliding member 6, and a second sliding member 14 is rotatably connected to the second sliding member 14. There is a second connecting rod 7. The upper left side of the mounting base 1 is rotatably connected to a first rotating rod 8. The first rotating rod 8 is rotatably connected to the second connecting rod 7. The upper left side of the mounting base 1 is also rotatably connected to a second rotating rod 9. The second rotating rod 9 is rotatably connected to the first connecting rod 2. The first rotating rod 8 is rotatably connected to a first contact wheel 10. The second rotating rod 9 is rotatably connected to a second contact wheel 11. The height of the first contact wheel 10 is higher than that of the second contact wheel 11. The mounting base 1 is provided with a correction mechanism 12.
[0023] like Figures 1-3 As shown, the correction mechanism 12 includes a first drive motor 121. The first drive motor 121 is mounted on the upper side of the middle part of the mounting base 1. A first lead screw 123 is connected to the output shaft of the first drive motor 121. The first lead screw 123 is threadedly connected to the first sliding member 6. A second drive motor 122 is also mounted on the upper side of the middle part of the mounting base 1. A second lead screw 124 is connected to the output shaft of the second drive motor 122. The second lead screw 124 is threadedly connected to the second sliding member 14.
[0024] It should be noted that when the rebar cage shifts during the welding process, this device is needed to correct the rebar cage welding machine. First, the device is fixed to the equipment base through the mounting holes. The triangular ribs can effectively improve the structural stability of the mounting base 1. Then, the first drive motor 121 and the second drive motor 122 in the correction mechanism 12 are activated. The output shaft of the first drive motor 121 rotates, driving the first lead screw 123 to rotate, which in turn drives the first sliding member 6 to slide along the limit frame 5, driving the second connecting rod 7 to move, thereby adjusting the first rotating rod 8 to a suitable height, causing the first contact wheel 10 to deflect, and at the same time, the second... The output shaft of the drive motor 122 rotates, causing the second lead screw 124 to rotate, which in turn causes the second sliding member 14 to slide along the limit frame 5, and drives the second connecting rod 7 to move, thereby adjusting the second rotating rod 9 to a suitable height, causing the second deflection wheel to deflect. The first contact wheel 10 and the second contact wheel 11 roll in contact with the surface of the rebar cage, and the radial offset of the rebar cage is sensed in real time. Through the correction mechanism 12, the rebar cage can be accurately corrected longitudinally. In order to achieve the effect of correcting the rebar cage laterally, the electric push rod 3 can be activated. The extension end of the electric push rod 3 drives the push plate 4 to move, thereby realizing the dynamic correction effect of the rebar cage welding machine in both the lateral and longitudinal directions.
[0025] Example 2
[0026] Based on Example 1, such as Figure 1 , Figure 4 and Figure 5 As shown, it also includes a contact mechanism 13, which includes a connecting rod 131. Several connecting rods 131 are connected to both the front and rear sides of the push plate 4, and two rotating rollers 132 are rotatably connected to each connecting rod 131.
[0027] It should be noted that when the electric push rod 3 drives the push plate 4 to move, the direct hard contact between the push plate 4 and the steel cage will cause material wear. When the push plate 4 contacts the steel cage, the rotating roller 132 can convert sliding friction into rolling friction, thereby avoiding long-term contact that will cause wear on the steel material and the push plate 4.
[0028] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
