Description

Technical Field

[0001] The utility model relates to the technical field of welding devices, in particular to a welding device for a longitudinal beam of a mining truck frame. Background Art

[0002] When welding the frame of a mining truck, all longitudinal beam components and cross beam components are usually placed and fixed on a special welding tool, and then multiple workers weld the frame. This welding method has some welding dead angles, so it is necessary to flip the entire frame after half of the welding is completed and then continue welding. At this time, the frame is not completely welded, and the structural strength of some parts is insufficient. A slight vibration during flipping will cause the longitudinal beams and cross beams to deform and crack, resulting in insufficient yield. At the same time, because the frame of a mining truck is extremely large, especially the longitudinal beams are extremely long, multiple workers are required to weld at the same time, which makes it difficult to control the welding quality. It requires multiple welders to have the same level. If one of them has a problem with the welding, the entire frame needs to be reworked, which seriously slows down production efficiency.

[0003] At present, the utility model with patent number CN208913421U discloses a longitudinal beam welding device, including a fixed bracket, one side of the fixed bracket is fixedly connected with a plurality of positioning plates, the other side of the fixed bracket is fixedly connected with a plurality of receiving plates, each receiving plate is respectively fixed with a plurality of first cylinders, the piston rod of each first cylinder is fixedly connected with a push plate, the bottom end of the push plate is overlapped with the edge of the fixed bracket, so that the longitudinal beam can be stably fixed on the fixed bracket for welding. However, this application scheme can only weld the longitudinal beam, but cannot weld the longitudinal beam together with the cross beam to form a whole frame after welding, which is not very convenient to use.

DETAILED DESCRIPTION

[0019] The following describes the mining truck frame longitudinal beam welding device of the present invention in conjunction with the accompanying drawings.

[0020] In the first embodiment of the present application, Figure 1 As shown, the mining truck frame longitudinal beam welding device (hereinafter referred to as "this patent") includes a welding robot running track 1, a welding robot moving platform 2, a welding robot 3, a welding frame support beam 4, a hydraulic telescopic column 5, a welding frame base 6, a welding frame flip drive seat 6-1, a welding frame 7, an end longitudinal beam control protrusion 7-1, a longitudinal beam groove 7-2, a cross beam groove 7-3, a frame assembly hydraulic control rod 7-4, an assembly control end 7-41, a hydraulic clamping block 7-42, a welding control island 7-5, a control island mounting beam 7-6, a welding frame rectangular frame 7-7, a frame beam preparation platform 8, a frame positioning block 8-1, a preparation platform translation track 9 and a working base 10, wherein the preparation platform translation track 9 is longitudinally installed on the upper surface of the working base 10, and the frame beam preparation platform 8 is translated on the preparation platform by a steel wheel driven by a motor. The frame beam preparation platform 8 moves back and forth on the track 9, so that the frame beam preparation platform 8 can move freely under and beside the welding frame 7, which is convenient for the staff to lift the longitudinal beam assembly and the cross beam assembly to the frame beam preparation platform 8. A welding frame 7 is arranged above the frame beam preparation platform 8. The two ends of the welding frame 7 are respectively connected to the welding frame base 6 through the welding frame flip driving seat 6-1. The upper part of the welding frame base 6 is connected to the welding frame support beam 4 through the hydraulic telescopic column 5. The two ends of the welding frame support beam 4 are respectively installed on the working base 10 through pillars. The welding frame support beams 4 at both ends of the welding frame 7 are connected by two welding robot running tracks 1. The welding robot mobile platform 2 moves back and forth on the welding robot running track 1 through gears and the toothed belt on the surface of the welding robot running track 1. The welding robot 3 is fixedly installed on the lower surface of the welding robot mobile platform 2.

[0021] The utility model number is CN208913421U, which is a longitudinal beam welding device (hereinafter referred to as "the patent"). The patent can only weld longitudinal beams, but cannot weld the longitudinal beams together with the cross beams to form a whole frame after welding. It is not very convenient to use. The present patent uses a flippable welding frame 7 to fix all longitudinal beam components and cross beam components, and performs necessary position changes when the welding robot 3 is welding, thereby providing a stable working platform for the welding robot 3.

[0022] The structure of the second embodiment is basically the same as that of the first embodiment, except that Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, the welding frame 7 includes an end longitudinal beam control protrusion 7-1, a longitudinal beam groove 7-2, a cross beam groove 7-3, a frame assembly hydraulic control rod 7-4, a welding control island 7-5, a control island mounting beam 7-6 and a welding frame rectangular frame 7-7. The end longitudinal beam control protrusions 7-1 are fixedly installed at both ends of the inner side of the welding frame rectangular frame 7-7, and the control island mounting beams 7-6 are fixedly installed on the lower surfaces of the two end longitudinal beam control protrusions 7-1. A plurality of welding control islands 7-5 are fixedly installed on the upper surface of the control island mounting beam 7-6. The end longitudinal beam control protrusions 7-1, a plurality of welding control islands 7-5 and the welding frame rectangular frame 7-7 are in the same plane. The gaps between the welding frame rectangular frame 7-7, the end longitudinal beam control protrusions 7-1 and the control island mounting beam 7-6 form longitudinal beam grooves 7-2 and cross beam grooves 7-3. The inner sides of the longitudinal beam grooves 7-2 and the cross beam grooves 7-3 are provided with paired and oppositely installed frame assembly hydraulic control rods 7-4. A frame positioning block 8 - 1 is fixedly installed on the upper surface of the frame beam preparation platform 8 .

[0023] In order to further optimize the working efficiency of this application, Figure 5 As shown, the surface of the welding control island 7-5 is prefabricated with two grooves corresponding to the control island mounting beam 7-6, and a hydraulic clamping block 7-42 is provided in the groove. The hydraulic clamping block 7-42 is clamped on both sides of the control island mounting beam 7-6, so that the welding frame 7 can replace the control island mounting beam 7-6 of various sizes as needed, and weld various types of frames at one time. The end of the frame assembly hydraulic control rod 7-4 is fixed with the mounting assembly control end 7-41, and the mounting assembly control end 7-41 can effectively increase the friction force, so that the frame assembly is fixed more stably.

[0024] When the utility model is in use, the specific operations are as follows:

[0025] When in use, the motor built into the frame beam preparation platform 8 drives the steel roller to move along the preparation platform translation track 9 out from under the welding frame 7. The staff first places the crossbeam assembly and the longitudinal beam assembly on the corresponding positions on the frame beam preparation platform 8 according to the design. The frame positioning block 8-1 can help position all the components during placement. After placement, the frame positioning block 8-1 retracts back into the frame beam preparation platform 8, and then the motor built into the frame beam preparation platform 8 drives the steel roller to move along the preparation platform translation track 9 to under the welding frame 7. The welding frame flipping drive seat 6-1 makes the welding frame 7 flip 180 degrees based on the welding frame base 6, so that the upper surface of the welding frame 7 faces the frame beam preparation platform 8. The frame beam preparation platform 8 cooperates to make fine adjustments to the welding frame 7 so that the longitudinal beam assembly and the cross beam assembly on it are aligned with the longitudinal beam groove 7-2 and the cross beam groove 7-3. The hydraulic telescopic column 5 extends to allow the welding frame 7 to descend, so that the longitudinal beam assembly and the cross beam assembly enter the longitudinal beam groove 7-2 and the crossbeam groove 7-3, at this time, the staff should fine-tune all the components to further ensure the subsequent welding quality, then the frame assembly hydraulic control rods 7-4 arranged in pairs are extended to clamp all the longitudinal beam assemblies and the crossbeam assemblies. The staff can further fine-tune all the frame assembly hydraulic control rods 7-4 at this time to ensure the correct position. After the clamping is completed, the hydraulic telescopic column 5 can lift the welding frame 7 to the working height. At this time, the welding robot 3 can weld one side of the longitudinal beam assembly and the crossbeam assembly. After welding one side, the welding frame flip drive seat (6-1) controls the welding frame (7) to flip 180 degrees, and the welding robot (3) can continue to weld the other side. When the welding robot 3 is working, the welding robot mobile platform 2 can drive the welding robot 3 to move on the welding robot running track 1, and cooperate with the welding frame flip drive seat 6-1 to slightly flip the welding frame 7 to further improve the welding quality.

[0026] In summary, the mining truck frame longitudinal beam welding device of the embodiment of the utility model is to place all the components of the longitudinal beam and cross beam of the mining truck frame on the frame beam preparation platform 8, and put all the components in place with the help of the frame positioning block 8-1 on the frame beam preparation platform 8, and then the hydraulic telescopic column 5 lowers the welding frame 7 to the same height of the components on the frame beam preparation platform 8, so that the longitudinal beam component enters the longitudinal beam groove 7-2, and the cross beam component enters the cross beam groove 7-3, and then the staff checks whether all the components are in place, and then the frame assembly hydraulic control rod 7-4 can be controlled to clamp all the frames. The components are assembled and the positions of all components are fine-tuned by extending and retracting the hydraulic control rod 7-4 of the frame component. Then the hydraulic telescopic column 5 lifts the welding frame 7 to a height that is convenient for the welding robot 3 to work. The welding robot 3 can weld one side. After welding one side, the welding frame flip driving seat 6-1 controls the welding frame 7 to flip 180 degrees. The welding robot 3 can continue to weld the other side, which can ensure the welding strength and weld the entire longitudinal beam at the same time. It can also weld the longitudinal beam to the cross beam to form a frame, which can effectively control the welding quality and improve production efficiency and yield rate.
