Technical Field
[0001] The present application relates to the technical field of welding tooling, and in particular to a welding tooling for a footrest bracket of a large engineering vehicle. Background Art
[0002] The footrest plays a key role in large engineering vehicles. It ensures the safety of the driver when getting on and off the vehicle, provides a stable foothold for the driver when getting on and off the vehicle, and as an integral part of the body structure, helps to enhance the structural stability and rigidity of the vehicle.
[0003] In the manufacturing process of large engineering vehicles, the footrest bracket is an integral part of the vehicle body structure, and the quality of the footrest bracket welding is particularly important.
[0004] Reference Figure 1 A large engineering vehicle footrest bracket includes two parallel angle steels 01 and side plates 02 welded together at the ends of the two angle steels 01. The two angle steels 01 are arranged at right angles relative to each other, and the bottom wall of the side plate 02 is arranged parallel to the bottom wall of the angle steel 01, and the connection between the angle steel 01 and the side plate 02 is perpendicular to each other.
[0005] When welding the above-mentioned large-scale engineering vehicle footrest bracket, one of the workers is required to accurately measure and control the docking position between the angle steel and the side panel using an angle ruler, and after the measurement, the other two workers are required to support the angle steel and the side panel respectively, and then the worker in charge of the measurement welds the connection between the angle steel and the side panel. In order to improve the welding accuracy, the workers who support the connection between the angle steel and the side panel need to be highly focused. However, the batch production of large-scale engineering vehicle footrest brackets will cause mental fatigue to the workers who support the angle steel and the side panel, causing the angle steel and the side panel to shift during the welding process, thereby reducing the welding quality of the finished large-scale engineering vehicle footrest bracket. Utility Model Content
[0006] In order to improve the welding quality of the finished footrest bracket, the present application provides a welding tool for a large engineering vehicle footrest bracket.
[0007] The welding tooling for a large engineering vehicle footrest bracket provided in this application adopts the following technical solution:
[0008] A welding tool for a footrest bracket of a large engineering vehicle comprises a workbench, on which a positioning seat is arranged, the width of the positioning seat matches the spacing between two angle steels on the product, the length of the positioning seat matches the spacing between two side panels on the product, and limiting plates are arranged on the opposite side walls of the workbench corresponding to the two side panels on the product, and the side panels on the product are limited between the limiting plates and the positioning seat along the length direction of the workbench.
[0009] By adopting the above technical solution, when assembling and welding the angle steel and the side panels, the welding accuracy of the footrest bracket can be improved by using the welding tooling. First, insert the two side panels between the limit plate and the positioning seat, and adjust the relative position of the side panels. Then, place the angle steel on the workbench between the two side panels and fit the positioning seat. Since the width of the positioning seat matches the spacing between the two angle steels, ensure that the angle steel can be firmly placed on the positioning seat. Then, only one worker is required to weld the connection between the angle steel and the side panel directly on the tooling. The setting of the welding tooling can significantly improve the positioning accuracy during welding, reduce the possibility of errors caused by human operation, and thus improve the welding quality and efficiency.
[0010] Optionally, top support plates are provided at both ends of the positioning seat along the length direction. The top support plates are located on opposite sides of the two side plates and are arranged to abut against inner walls on opposite sides of the two side plates.
[0011] By adopting the above technical solution, the setting of the top support plate can further increase the contact area with the side plate, thereby generating additional supporting force for the side plate, further reducing the possibility of deformation or displacement of the side plate during welding.
[0012] Optionally, the top support plate and the positioning seat are detachably arranged, and a plurality of vertically arranged plug-in rods are arranged at the bottom of the top support plate along the length direction, and plug-in holes are opened at the top of the positioning seat corresponding to the plug-in rods, and the plug-in rods and the plug-in holes correspond one-to-one and are plug-matched.
[0013] By adopting the above technical solution and the detachable setting of the top support plate, when removing the welded footrest, the staff only needs to lift the footrest to the height of the positioning seat to remove the footrest, which provides labor-saving effect for the staff in unloading.
[0014] Optionally, the top support plate is arranged in a right-angle trapezoidal shape, and the inclined surface of the top support plate is located on the side away from the limiting plate.
[0015] By adopting the above technical scheme, the right-angle trapezoidal setting of the top support plate not only reduces the manufacturing cost of the top support plate, but also, by setting the bottom size of the top support plate larger than the top size, it is convenient for the top support plate to disperse the stress to the workbench when it is resisted and squeezed by the side plate, thereby enhancing the supporting force of the top support plate on the side plate and further improving the positioning accuracy of the side plate during welding.
[0016] Optionally, a slot for plugging the top support plate is provided between the limit plate and the top support plate on the workbench, both ends of the slot extend to the side walls of the workbench, and the depth of the slot is matched with the height difference between the product angle steel and the side plate.
[0017] By adopting the above technical solution, the setting of the slot makes it easy for the staff to fine-tune the position of the side panel along the length direction of the slot, and the depth of the slot is matched with the height difference between the product angle steel and the side panel, which can ensure the height difference between the angle steel and the side panel on the product, improve the verticality of the side panel, and further improve the welding accuracy between the side panel and the angle steel and the stability of the welding process.
[0018] Optionally, a positioning block is provided on both sides of the card slot corresponding to the length direction of the side panel, the positioning block is configured to interfere with the side wall of the side panel, and vertical grooves are correspondingly opened on both sides of the bottom wall of the card slot along the length direction of the side panel, and a plug-in column is inserted into the vertical groove, the plug-in column is plugged into the vertical groove, and the plug-in column is arranged on the positioning block.
[0019] By adopting the above technical solution, the side panel can be limited in the length direction of the slot by inserting the positioning block in the slot, so that the side panel is fixed during the welding process, further improving the stability of the side panel during the welding process. At the same time, the positioning block is inserted into the vertical slot and the plug-in column to achieve a detachable setting. While providing a reliable support and positioning effect, it is also convenient for the side panel to slide from the slot to the specified position during loading, thereby avoiding the need for the staff to lift the side panel until it reaches the specified position before inserting it into the slot, providing a labor-saving effect for the staff to load the material.
[0020] Optionally, grooves are provided on both sides of the workbench in the width direction, each of the grooves extends to the side wall of the workbench, and a support plate for supporting the angle steel is hinged on the side of the groove facing the angle steel, and a placement groove is also provided on the inner bottom wall of the groove, an abutment rod is placed in the placement groove, and a clamping groove is provided on the opposite sides of the inner bottom wall of the groove and the abutment plate corresponding to the end of the abutment rod, and the end of the abutment rod is plugged into the clamping groove, and when the end of the abutment rod is inserted into the clamping groove, a right triangle is formed between the abutment rod, the groove and the support plate, and at this time, the support plate is in contact with the side wall of the angle steel.
[0021] By adopting the above technical solution, the abutment plate is turned over and the abutment rod is taken out from the placement groove, and its end is correspondingly inserted into the clamping groove, so that a right-angled triangle structure is formed between the abutment rod, the groove and the abutment plate, which can support the angle steel; conversely, it can be stored to facilitate the staff to place the angle steel on the workbench before a new round of welding work. The setting of the abutment plate can effectively prevent the angle steel from moving or tilting during the welding process, thereby ensuring the welding accuracy and welding quality of the footrest bracket.
[0022] Optionally, a handle is provided on a side of the abutment plate away from the hinge.
[0023] By adopting the above technical solution, in order to facilitate the staff to adjust the position of the support plate more easily, a handle is further provided on the side of the support plate away from the hinge. Through the design of the handle, the staff can easily lift or put down the support plate, thereby improving work efficiency and convenience of operation.
