Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of loader rocker arm welding, in particular to a welding jig for a loader rocker arm assembly. Background Art
[0002] The motion mechanism of the loader's working device is a parallelogram mechanism, including a boom, a rocker arm, a connecting rod and other components. The rocker arm is responsible for connecting the bucket cylinder, the boom and the connecting rod, and can withstand high-intensity pulling. Its structural strength, overall dimensions, shaft hole dimensions and relative position are very critical.
[0003] The rocker arm is composed of two identical special-shaped rocker arm plates as the main body, and multiple internal reinforcement plates (short reinforcement plates, special-shaped reinforcement plates) and shaft sleeves welded together. Due to the irregular shape of the rocker arm plates, conventional welding uses the three shaft holes of the rocker arm as the reference positioning, and welding is performed after the process shaft is inserted. However, due to the large number of welds and staggered welds after the multiple reinforcement plates in the rocker arm are spliced, welding deformation is inevitable. After welding is completed, the process shaft cannot be removed smoothly. The process has a great damage to the size of the hole, affecting the next step of processing.
[0004] There is no pre-installed tire or tooling that is very suitable for loader rocker arm welding in the prior art (due to differences in workpiece size, specifications, and structural composition, it is difficult for general pre-installed tires to be universal). Utility Model Content
[0005] The utility model provides a welding jig for a loader rocker arm assembly, which can solve the problems pointed out in the background technology.
[0006] A welding jig for a loader rocker arm assembly comprises a base plate, a limiting support assembly located on both sides of the base plate, and a plurality of outer edge limiting members. The limiting support assembly comprises positioning limiting supports on both sides and a limiting support crossbeam connected to the positioning limiting supports on both sides.
[0007] Preferably, the limiting support beam and the positioning limiting supports on both sides are detachably connected.
[0008] Preferably, the positioning and limiting supports on both sides are provided with corresponding limiting grooves, and the limiting support beam is limited by the limiting grooves on both sides to achieve a detachable connection.
[0009] Preferably, a reinforcing plate limiting member is provided on at least one end of the inner side surface of the limiting support beam.
[0010] Preferably, the plurality of outer edge limiting members include side outer edge limiting members and top outer edge limiting members.
[0011] Preferably, the number of the side outer edge limiting members is at least two, and the number of the top outer edge limiting members is at least one.
[0012] Beneficial effects: The utility model provides a welding jig for a loader rocker arm assembly, which is suitable for positioning welding of the loader rocker arm assembly and has the advantages of easy operation, high welding precision, and high welding efficiency.

DETAILED DESCRIPTION
[0019] A specific embodiment of the present invention will be described in detail below with reference to the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiment.
[0020] Example 1:
[0021] like Figure 1 As shown, a welding jig for a loader rocker arm assembly includes a base plate 1, limit support assemblies located on both sides of the base plate 1, and several outer edge limit assemblies. The limit support assemblies include positioning limit supports 31 on both sides and limit support beams 32 connected to the positioning limit supports 31 on both sides. The several outer edge limit assemblies limit and position the outer edge of the workpiece, the positioning limit supports 31 on both sides limit and position the bottom rocker arm plate 10, the limit support beams 32 limit and position the short reinforcement plate 30, and provide limit support for the top rocker arm plate 20.
[0022] Specifically, several outer edge limiting components include side outer edge limiting parts 21 and top outer edge limiting parts 22. The number of side outer edge limiting parts 21 is at least two, and the number of top outer edge limiting parts 22 is at least one, that is, at least three points of limiting and positioning are adopted to ensure positioning accuracy.
[0023] Specifically, at least one end of the inner side surface of the limiting support beam 32 is provided with a reinforcing plate limiting member 34 , and the reinforcing plate limiting member 34 limits and positions the short reinforcing plate 30 .
[0024] In some embodiments, the limiting support beam 32 and the positioning limiting supports 31 on both sides are detachably connected.
[0025] Specifically, corresponding limiting grooves 33 are provided on the positioning and limiting supports 31 on both sides, and the limiting support beam 32 is limited by the limiting grooves 33 on both sides to achieve a detachable connection; the detachable connection facilitates the placement of the bottom rocker plate 10 into the mold, and different limiting support beams 32 can be replaced as required to match it with the workpiece.
[0026] The working principle or usage of this utility model:
[0027] 1. Place the bottom rocker plate 10 flat on the base plate 1, with its ends inserted into the inner sides of the support frames on both sides to limit its position. The bottom rocker plate 10 is in contact with the side outer limiters 21 and the top outer limiter 22, respectively.
[0028] 2. According to the processing size requirements, select the appropriate limit support beam 32 and place it in the limit groove 33;
[0029] 1. Position the short reinforcement plate 30 in contact with the limit support beam 32, and position the remaining special-shaped reinforcement plates 40 and the shaft sleeve according to the size requirements. After placement, fix them to the bottom rocker plate 10 with electric welding;
[0030] 2. After spot welding, place the top rocker plate 20 and position it in contact with the side outer edge limiter 21 and the top outer edge limiter 22. After positioning, perform electric welding to fix the top rocker plate 20.
[0031] 3. After spot welding is completed, the welded rocker arm assembly is lifted, and the limit support beam 32 is lifted together with the rocker arm assembly. The limit support beam 32 falls off naturally or is removed manually.
[0032] The above disclosures are only a few specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the scope of protection of the present invention.
