Description

Technical Field

[0001] The utility model relates to the technical field of water heater heat pump processing, in particular to a clamping tool for reinforcing rod welding. Background Art

[0002] The reinforcing rods are uniformly welded to the heating tubes to strengthen the structure of the heating tubes. However, during welding, the operator cannot ensure that the reinforcing rods are neatly arranged, which affects the welding effect and reduces the structural strength of the heating tubes. Of course, in order to ensure that the reinforcing rods do not move during welding, the ends of the reinforcing rods are often clamped by clamps. This clamping method is a closed clamping method, so it is not convenient to evenly arrange and place the reinforcing rods. Utility Model Content

[0003] The utility model provides a clamping tool for reinforcing rod welding to solve the deficiencies of the prior art, facilitate the arrangement, placement and clamping operations of the reinforcing rods, and has strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technologies are proposed:

[0006] A rotating seat is provided on the outer wall of the lower clamping plate, a rectangular frame is rotatably provided on the rotating seat, an upper plate is provided at the upper end of the vertical section of the rectangular frame, a second spring is provided on the lower side of the upper plate, a lower plate is provided at the lower end of the second spring, a pressure rod is movably provided on the vertical section of the rectangular frame, the lower plate is provided on the pressure rod, an extension platform is provided on the upper clamping plate, a pair of U-shaped grooves are provided at the outer end of the extension platform, an inclined surface is formed at the upper end of the extension platform, the outer end of the inclined surface extends downwardly, a slot is provided at the upper end of the extension platform, and the pressure rod is located in the slot. Through the provided pressure rod and the second spring, the rectangular frame can be rotated when clamping, so that the pressure rod acts on the upper end of the extension platform, so that the restoring deformation force provided by the second spring and the spring can ensure the clamping effect of the upper clamping plate and the lower clamping plate on the reinforcing rod, and the setting of the U-shaped groove plays a limiting role on the pressure rod to ensure the stability of clamping.

[0007] Furthermore, a plurality of arc grooves are provided on the lower wall of the upper splint and the upper wall of the lower splint. The arc grooves on the lower splint facilitate the uniform arrangement of the reinforcing rods, while the upper splint limits the reinforcing rods to prevent the reinforcing rods from moving during transfer and welding, thereby affecting the welding effect.

[0008] Furthermore, a rubber pad is provided in the arc groove to ensure the clamping effect.

[0009] Furthermore, a concave handle is provided on the upper clamping plate to facilitate the clamping and transfer operation of the reinforcing rod. The advantages of the above technical solution are:

[0015] like Figure 1~Figure 3 As shown, a clamping tool for reinforcing rod welding includes a bottom plate 1, on which a plurality of pairs of vertical rods 2 are mounted, each pair of vertical rods 2 is sleeved with a sleeve plate 3, and the sleeve plates 3 located on the same side are provided with a lower clamp plate 30, and the two ends of the lower clamp plate 30 are respectively hinged with a pair of rotating plates 31, and the rotating plates 31 are provided with a spring pin 32, and the spring pin 32 is sleeved with a spring 33, and the spring pin 32 is sleeved with a second rotating plate 34, and the second rotating plate 34 is located at the upper end of the spring 33, and the upper end of the lower clamp plate 30 is provided with an upper clamp plate 35, and the second rotating plate 34 is rotatably arranged at the two ends of the upper clamp plate 35, and the upper clamp plate 35 is provided with a concave handle 310. The lower wall of the upper clamp plate 35 and the upper wall of the lower clamp plate 30 are provided with a plurality of arc grooves, and rubber pads are provided in the arc grooves.

[0016] A rotating seat 4 is provided on the outer wall of the lower clamping plate 30, and a rectangular frame 40 is rotatably provided on the rotating seat 4. An upper plate 41 is provided at the upper end of the vertical section of the rectangular frame 40, and a second spring 42 is provided on the lower side of the upper plate 41. A lower plate 43 is provided at the lower end of the second spring 42. A pressure rod 44 is movably provided on the vertical section of the rectangular frame 40, and the lower plate 43 is provided on the pressure rod 44. An overhanging platform 47 is provided on the upper clamping plate 35, and a pair of U-shaped grooves 46 are provided at the outer end of the overhanging platform 47. The upper end of the overhanging platform 47 is formed with an inclined surface, and the outer end of the inclined surface extends downwardly. A slot 48 is provided at the upper end of the overhanging platform 47, and the pressure rod 44 is located in the slot 48.

[0017] When placing and clamping the reinforcing rod in this embodiment, the operator first rotates the upper clamping plate 35 outward, and then exposes the arc groove on the lower clamping plate 30, and then the operator places the reinforcing rod in the arc groove. After placement is completed, the operator rotates the upper clamping plate 35 through the concave handle 310, so that the upper clamping plate 35 is located directly above the lower clamping plate 30, and then rotates the rectangular frame 40 so that the rectangular frame 40 drives the pressure rod 44 through the inclined surface and enters the slot 48. After entering the slot 48, the restoring deformation force provided by the second spring 42 and the restoring deformation force provided by the spring 33 will make the upper clamping plate 35 act stably on the reinforcing rod. After completing clamping, the operator places the wavy heating tube on the bottom plate 1, and then puts the sleeve plate 3 on the vertical rod 2, and finally makes the reinforcing rod and the heating tube contact, and then performs welding operation. After welding, the clamping is cancelled and the heating tube is taken out.
