Description

Technical Field

[0001] The present invention relates to the technical field of building material production, and particularly to a semi-automatic welding working device for trusses. Background Art

[0002] In the production line of manufacturing trusses, the steel bar skeletons are cut to obtain trusses of different lengths to meet the engineering requirements. The cut ends of the steel bar skeletons form the ends of two trusses. Usually, cross support bars are welded to the two ends respectively to reinforce the strength of the trusses. The cross support bars are composed of horizontal and vertical steel bars. The above-mentioned welding work requires fixing and aligning the horizontal and vertical steel bars to the two ends of the trusses. The prior art uses manual welding, which has low efficiency and affects the truss production process. In order to improve production efficiency and achieve batch welding, it is necessary to design a device for semi-automatic welding of cross support bars at the ends of trusses using a robot. Summary of the Invention

[0003] In view of the above deficiencies of the prior art, the present invention invents a semi-automatic welding working device for trusses.

[0004] To achieve the above object, the present invention adopts the following technical solutions:

[0005] The semi-automatic welding working device for trusses includes a chassis, a truss template, a cross positioning block, and a welding robot. A plurality of truss templates are arranged side by side on the top surface of the chassis, and a cross positioning block is fixedly arranged at the front end of the truss template; a welding robot is installed in front of the chassis.

[0006] The innovation of the present invention lies in designing a device used in cooperation with a welding robot. After the truss is placed manually first and then the robot is controlled for automatic welding, the function of batch welding trusses is realized, and the labor intensity of workers is reduced.

[0007] Further, the truss template is a triangular template, and the triangular template is matched with the structure of the truss. After the truss is placed on it, it can be placed stably without shaking or moving.

[0008] Further, the cross positioning block includes a base, a convex block, and a top pin. There are 3 convex blocks arranged in an inverted "pin" shape on the base, and the top pin is arranged on the convex block at the bottom, which is convenient for placing the horizontal and vertical steel bars and matching with the end positions of the trusses for subsequent welding; and the height of the vertical steel bar can be adjusted by adjusting the top pin to meet the welding requirements.

[0009] Furthermore, it also includes a truss clamping device, which includes a cross frame, a clamping cylinder and a pressure plate. The cross frame is fixedly arranged across the base frame, and a downward clamping cylinder is fixedly arranged on the cross frame. A pressure plate is fixedly arranged on the clamping cylinder, and the pressure plate is located directly above the truss formwork. The truss clamping device is used to press the truss tightly against the truss formwork, so that the truss does not shake during subsequent welding.

[0010] Furthermore, it also includes an alignment device, which includes a slide rail, a slide rod, an end positioning block and a lifting cylinder. A vertical slide rail is set on each of the left and right sides of the front of the base frame. The slide rod is slidably set on the two slide rails, and the end positioning block is set on the slide rod and corresponds to the cross positioning block one by one; the base frame is provided with a lifting cylinder that drives the slide rod to slide up and down. The function of the alignment device is to align the ends of the trusses into rows when placing them, so as to avoid uneven ends that cause the subsequent welding robot to be unable to weld.

[0011] Furthermore, the end positioning block is a U-shaped positioning block. After the end positioning block moves up, the cross positioning block is stuck in the end positioning block. The end positioning block is mainly used to position the two main reinforcements at the bottom of the truss, avoiding interference between the end positioning block and the cross positioning block.

[0012] Furthermore, it also includes a track and a movable frame. The track is fixedly placed at the rear of the base frame, and the movable frame is slidably set on the track. Since the truss is relatively long, if there is only a rear support point at the welded end, the rear part may be bent under its own weight, so it is necessary to set a track and a movable frame to place and support the rear half of the truss so that it can always remain in a horizontal state.

[0013] The advantages of the present invention are: the present invention adopts the truss placement frame and the welding robot to cooperate with each other, thereby realizing batch semi-automatic welding of the cross support ribs of the truss end, reducing the labor intensity of workers and improving work efficiency; its overall structure is simple and easy to manufacture, and is suitable for use in all links of building material production.

On the top surface of the chassis 1, 9 truss templates 2 are arranged side by side, and the truss templates 2 are spaced apart from each other. The truss template 2 is a triangular template, which matches the structure of the truss 9 and facilitates the stable placement of the truss 9. A cross-shaped positioning block 3 is fixedly arranged at the front end of the truss template 2, and the cross-shaped positioning block 3 is used to place horizontal steel bars and vertical steel bars.

The thimble 33 is arranged on the convex block 32 at the bottom, and the thimble 33 is connected to the convex block 32 by screw rotation. When placing the cross-shaped support bar 10, the horizontal steel bar is inside, and the vertical steel bar is outside and is lifted by the thimble 33.
