Technical Field

[0001] The utility model relates to the field of steel cage welding, in particular to a welding positioning and clamping device for a steel cage rolling welding machine. Background Art

[0002] As an important equipment in construction, the steel cage rolling welding machine has strict requirements on the welding quality of the steel cage wrapped with steel bars during its use.

[0003] The current steel cage rolling welding machine uses a roller-type positioning device for winding steel bars, that is, the wound steel bars are pressed against the surface of the distribution bars by rollers, and when the steel bars pass through the rollers, the rollers rotate synchronously.

[0004] However, when the above device encounters raw materials with larger diameter and higher strength, the rollers are severely worn, causing great damage to the machine, causing large left and right swings, uneven spacing of the steel bar windings, and easy derailment and ejection, posing a safety risk. In addition, after the rollers are worn, the wound steel bars are difficult to compact, resulting in low welding quality.

[0005] Therefore, it is necessary to develop a welding positioning and clamping device for a steel cage rolling welding machine. Utility Model Content

[0006] The purpose of the utility model is to solve the problems of unstable welding quality, loose clamping, easy derailment, frequent component replacement, etc. when winding and welding a steel cage made of larger diameter raw materials; a welding positioning and clamping device for a steel cage rolling welding machine is designed to solve the problems of frequent component replacement, easy derailment, etc., and improve the welding quality.

[0007] In order to achieve the above-mentioned purpose, the utility model provides a welding positioning and clamping device for a steel cage rolling welding machine, which adopts the following technical scheme, including: a front correction wheel ground support column and a ground support tripod fixedly arranged on the ground, a front correction wheel is arranged on the top of the front correction wheel ground support column, a rear correction wheel is arranged on the top of the ground support tripod, a hard positioning steel plate with a groove is arranged above the side of the ground support tripod away from the front correction wheel ground support column, and rolling welding machine rollers are arranged on the inner sides of the front correction wheel, the rear correction wheel and the hard positioning steel plate with grooves.

[0008] Furthermore, a steel plate support is provided on one side of the grooved hard positioning steel plate away from the roller of the seam welding machine, and a hydraulic support arm is provided on the other side of the steel plate support.

[0009] Furthermore, the steel plate support is provided with a plurality of bolt positioning holes, and the grooved hard positioning steel plate is provided with a plurality of bolt fixing holes, the bolt positioning holes correspond to the bolt fixing holes in one-to-one position, and the grooved hard positioning steel plate is fixed to the steel plate support by passing fixing bolts through the bolt positioning holes and the bolt fixing holes.

[0010] Furthermore, a hard positioning steel plate groove is provided through the middle of the grooved hard positioning steel plate from top to bottom.

[0011] Furthermore, the height of the front correction wheel is lower than that of the rear correction wheel, and the height of the rear correction wheel is lower than that of the hard positioning steel plate groove. The front correction wheel, the rear correction wheel and the hard positioning steel plate groove form an arc with the center direction pointing to the roller of the seam welding machine.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The utility model uses a grooved hard positioning steel plate for positioning, avoiding the defects of the prior art in the processing of large-diameter steel bar raw material steel cage, such as large mechanical wear, frequent component replacement, derailment, left and right swinging, uneven distribution of steel bars, etc. By sliding instead of rolling, the welding positioning process is more stable.

[0014] 2. The utility model uses the cooperation of the grooved hard positioning steel plate, the steel plate support and the hydraulic system to make the steel bars tighter and easier to maintain.

[0025] A hard positioning steel plate 4 with grooves is arranged above the ground supporting tripod 9 away from the front correction wheel ground supporting column 6. Specifically, a hard positioning steel plate groove 7 is arranged through the middle of the hard positioning steel plate 4 with grooves from top to bottom.

[0026] In a specific embodiment, a steel plate support 3 is provided on the side of the grooved hard positioning steel plate 4 away from the roller 1 of the seam welding machine, and a hydraulic support arm 2 is provided on the other side of the steel plate support 3, and the hydraulic support arm 2 is connected to a wall or other fixed structure.
