Description

Technical Field

[0001] The invention relates to the technical field of welding tooling, and in particular to an adjustable steel bar angle welding auxiliary tooling. Background Art

[0002] Rebar welding is the process of extending or cross-connecting rebars axially using electric welding equipment. During cross welding, the rebars often need to be fixed according to the required welding angle to prevent the rebars from moving and shifting during the welding process and to ensure the quality of the rebar angle welding.

[0003] In traditional angle welding of steel bars, it is necessary to manually use a protractor (such as a square) to measure and locate the angle between the two steel bars, and then use a clamp to fix the two steel bars placed at an angle separately; however, the angle of the protractor used for locating the steel bar angle is a fixed angle. When welding at a different angle is required, the corresponding protractor needs to be replaced for angle positioning, resulting in the steel bar angle welding being limited by the angle of the protractor, which is not convenient for the steel bar angle welding work.

[0066] Principle and advantages of adjustable steel bar angle welding auxiliary tooling:

[0067] First, when the rotating disk 21 rotates a certain angle each time to butt the two steel bar bodies 100 to form a welding angle, a corresponding length of the steel bar body 100 will be generated between the welding point of the welding angle and the fixing component 23, that is, each welding angle corresponds to a certain length of the steel bar body 100. Therefore, before positioning, the required welding angle is input through the operation panel 15, and the operation panel 15 can control the electric push rod B31 to push the positioning block 3 to slide, so that the positioning block 3 moves closer to or away from the rotating disk 21, that is, adjust the positioning length of the positioning block 3 to the steel bar body 100; then the two steel bar bodies 100 are placed on the inner sides of the positioning grooves 22 at the tops of the two rotating disks 21 respectively, and after the clamping mechanism 5 clamps one of the steel bar bodies 100 that rotates first, the end of the steel bar body 100 is beveled by grinding or cutting equipment to ensure the stability of the butt joint of the end of the steel bar body 100, and then it is fixed by the fixing component 23 and then the clamping mechanism 5 is released. Clamping; under the drive of the two driving motors 24, the rotating disk 21 is rotated in succession to drive the steel bar body 100 to start docking. At this time, the angle sensor 27 detects the rotation angle of the rotating disk 21. When the rotation angle of the two rotating disks 21 reaches the rated angle, the rotating disk 21 drives the steel bar body 100 to complete the docking and stop rotating. Under the action of the rotating disk 21 and the fixing component 23, the stability of the welding angle is maintained to facilitate subsequent welding work; during the welding process, the welding table 1 is driven by the electric push rod A14 to rotate on the top of the base plate 12, so that the welding surface at the bottom of the steel bar body 100 can be flipped to one side to ensure comprehensive welding of the welding angle. When the welding is completed, the welding table 1 is rotated downward under the drive of the electric push rod A14, and the push plate 42 is pushed upward by the push member 17 on the top of the base plate 12, so that the push plate 42 pushes the push member 4 through the connecting rod 41 to push the steel bar body 100 welded on the inner side of the positioning groove 22 out to facilitate unloading after welding.

[0068] Its advantage is that the length and rotation angle of the steel bar body 100 can be automatically positioned according to the required welding angle. On the basis of this positioning, when the steel bar body 100 is fixed by the fixing component 23, the steel bar body 100 can be automatically connected to form a welding angle under the drive of the rotating disk 21, and the stability of the welding angle is guaranteed during the welding process. It can be adjusted according to the size of the welding angle to adapt to different welding angles and prevent the positioning of the welding angle from being limited by the positioning tool; at the same time, it can be flipped during the welding process to ensure that the angle is fully welded. After welding is completed, the steel bar body 100 welded inside the positioning groove 22 can be pushed out by the pushing piece 4 to facilitate unloading after welding.

[0069] When the butt joint assembly 2 in the adjustable steel bar angle welding auxiliary tooling of the present application is butt jointed after the steel bar body 100 is fixed, the swing arm 25 is first driven to rotate by the driving motor 24, so that the swing arm 25 drives the pin shaft 236 to move horizontally. When the pin shaft 236 moves horizontally, it drives the wedge-shaped slider 235 to slide obliquely upward to press the inclined slide 234 downward, so that the inclined slide 234 presses the clamping block 231 to press the steel bar body 100 inside the positioning groove 22. At this time, the clamping block 231 squeezes the spring 233 on the outer side of the slide rod 232; as the swing arm 25 continues to rotate, the wedge-shaped slider 235 cannot continue to slide, and then starts to drive the rotating disk 21 to rotate under the action of the swing arm 25, so that the rotating disk 21 drives the shaft body 26 to rotate inside the shaft sleeve 19. Specifically, the power output by the driving motor 24 is large The rotation resistance of the rotating disk 21, and the sliding resistance between the wedge-shaped slider 235 and the inclined slide 234 is less than the rotation resistance of the rotating disk 21; thereby realizing the fixing and docking action of the steel bar body 100. During the welding process, the driving motor 24 realizes self-locking under the action of the control system to ensure the stability of the driving end. When the angle welding of the steel bar body 100 is completed, the driving motor 24 is reversed to drive the wedge-shaped slider 235 to slide obliquely downward, so that the inclined slide 234 gradually releases the pressure on the clamping block 231. At this time, the spring 233 pushes the clamping block 231 to move upward and reset, thereby releasing the fixation of the steel bar body 100 to facilitate unloading. After unloading, the driving motor 24 continues to reverse to make the wedge-shaped slider 235 push the block 237 to drive the rotating disk 21 to reverse and reset.

[0070] It is worth mentioning that the above fixed docking method has the following advantages:

[0071] Advantage 1: After the steel bar body 100 inside the positioning groove 22 is positioned by the positioning block 3, it is only necessary to start the driving motor 24 to realize the automatic fixing action, and there is no need to manually fix the two steel bar bodies 100 separately, making the operation more convenient.

[0072] Advantage 2: After the driving motor 24 drives the fixing assembly 23 to complete the welding action, the driving motor 24 automatically drives the rotating disk 21 to start rotating when the driving motor 24 is operating normally, until the rotating disk 21 rotates to the rated angle, so as to automatically dock the steel bar body 100, and the fixing assembly 23 can adapt to the fixing action of steel bars of different diameters, preventing overpressure or inadequate tightening of the steel bar body 100.

[0073] Advantage three: after welding, the unfixing action and the driving disk 21 can be driven to reversely reset by running the driving motor 24 in reverse order to facilitate subsequent continuous use.

[0074] In actual application, when one of the steel bar bodies 100 that rotates first is clamped by the clamping mechanism 5, the electric push rod D510 drives the sliding pin 59 to slide on the inner side of the driving plate A55 and the driving plate B57. At this time, the sliding pin 59 is located on the inner side of the horizontal slot hole A551 and the inclined slot hole B571. Under the action of the horizontal slot hole A551 and the inclined slot hole B571, the sliding pin 59 first pushes the driving plate B57 to move upward, thereby driving the lower clamping block 52 to move upward from the inner side of the slide groove 110 to the outer side of the steel bar body 100, thereby supporting the bottom of the steel bar body 100. When the sliding pin 59 slides from the inclined slot hole B571 into the horizontal slot hole B572, the sliding pin 59 simultaneously slides from the horizontal slot hole A551 into the inner side of the inclined slot hole A552, thereby driving the sliding pin 59 to drive the driving plate A55 to move downward, thereby driving the upper clamping block 51 to move toward the steel bar body. The top of the body 100 is approached until it is pressed tightly, and finally, the arc-shaped pressure pad B511 at the bottom of the lower clamping block 52 and the upper clamping block 51 realizes the clamping and fixing of the steel body 100. At this time, the end of the steel body 100 can be processed so that the end has a certain inclination angle when butt-jointed to ensure the stability during butt welding; when the end processing is completed, the electric push rod C54 drives the slide seat 53 to slide along the slide rail 111, and then the upper clamping block 51 and the lower clamping block 52 drive the end of the steel body 100 to approach the outside of the positioning block 3 for positioning, and finally the electric push rod D510 drives the sliding pin 59 to slide in the opposite direction, so that the upper clamping block 51 and the lower clamping block 52 are reset away from the steel body 100 in turn, and the reset lower clamping block 52 is located below the steel body 100 to prevent the subsequent rotation and docking action of the steel body 100 from being hindered.

[0075] It is worth mentioning that the above fixing method has the following advantages:

[0076] Advantage 1: By setting up the clamping mechanism 5, the steel bar body 100 can be clamped and fixed before the length is positioned, so as to facilitate the processing of the end of the steel bar body 100, and after processing, the end face is kept fixed and positioned close to the positioning block 3 to prevent the end face of the steel bar body 100 from deflecting during the docking process, thereby ensuring the stability of the angle welding.

[0077] Advantage 2: When clamping the steel bar body 100, the electric push rod D510 drives the sliding pin 59 to slide, so as to drive the lower clamp block 52 and the upper clamp block 51 closer to the steel bar body 100, and the bottom of the V-shaped groove inside the lower clamp block 52 is flush with the bottom of the positioning groove 22, which can ensure that the steel bar body 100 inside the positioning groove 22 is in a horizontal state under the support of the lower clamp block 52, preventing the subsequent fixing component 23 from being unstable when fixing the steel bar body 100, so as to facilitate the post-fixing processing of the steel bar body 100, and at the same time, the upper clamp block 51 can be driven downward to press tightly to adapt to the clamping and fixing of steel bar bodies 100 of different diameters.

[0078] Advantage three, when the steel bar body 100 is fixed on the inner side of the positioning groove 22 by the fixing assembly 23, the sliding pin 59 is driven by the electric push rod D510 to slide in the opposite direction to drive the upper clamping block 51 and the lower clamping block 52 to reset in sequence, while releasing the fixation of the steel bar body 100, preventing the lower clamping block 52 from hindering the subsequent rotational docking of the steel bar body 100.

[0079] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
