Description

Technical Field

[0001] This utility model relates to the field of electric garbage truck manufacturing technology, and in particular to a welding fixture for a lever brake rocker arm of an electric garbage truck. Background Technology

[0002] The lever brake of the electric garbage transport (tricycle) is shown in "Patent Publication No. CN218559077U, entitled A Lever Brake Rocker Arm Structure for an Electric Tricycle", which has a rocker arm 200 mounted on the rotating shaft 100. Figures 1 to 3 As shown, the lever brake rocker arm is composed of two rocker arm plates (i.e., the first rocker arm plate 210 and the second rocker arm plate 220) welded back to back, forming a Y-shape. In traditional lever brake rocker arm welding, the first rocker arm plate 210 and the second rocker arm plate 220 are placed back to back and clamped using a jig. After welding one side of the first rocker arm plate 210 and the second rocker arm plate 220, the clamp is released, the first rocker arm plate 210 and the second rocker arm plate 220 are flipped over, and then clamped again. Only in this way can the welding connection of the first rocker arm plate 210 and the second rocker arm plate 220 be completed. Therefore, the above welding operation is extremely inefficient.

[0003] Therefore, there is an urgent need to propose a simple and reliable welding fixture for the lever brake rocker arm of an electric garbage truck. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide a welding fixture for the lever brake rocker arm of an electric garbage truck. The technical solution adopted by this utility model is as follows:

[0005] A welding fixture for a lever brake rocker arm of an electric garbage truck clamps a first rocker arm plate and a second rocker arm plate; the first and second rocker arm plates are back-to-back forming a Y shape. The first and second rocker arm plates have the same structure, and the first rocker arm plate includes a pivot connection end, an arc-shaped end, and a crank arm connection end connected in sequence; the welding fixture for the lever brake rocker arm of the electric garbage truck includes a lower support block, a rear support strip and a front support strip fixed on the lower support block and arranged perpendicularly to each other, and several clamping isolation blocks fixed on the rear support strip and the front support strip and arranged along the length direction of the rear support strip and the front support strip; the several clamping isolation blocks are evenly spaced; the distance between adjacent clamping isolation blocks is equal to twice the thickness of the pivot connection end; the pivot connection ends of the first rocker arm plate and the second rocker arm plate are placed between adjacent clamping isolation blocks.

[0006] Furthermore, the clamping isolation block is in the shape of a right trapezoid.

[0007] Compared with the prior art, the present invention has the following beneficial effects:

[0008] (1) This utility model, by setting a rear support bar, a front support bar, and clamping isolation blocks, with the spacing between adjacent clamping isolation blocks equal to twice the thickness of the pivot connection end, facilitates the placement of the pivot connection ends of the first rocker arm plate and the second rocker arm plate between adjacent clamping isolation blocks, ensuring their clamping reliability. The pivot connection end, the arc-shaped end, and the crank arm connection end are not on the same plane. Traditional clamps cannot guarantee efficient back-to-back clamping of the first and second rocker arm plates. This invention utilizes the rear and front support bars for support and the clamping isolation blocks for clamping, ensuring reliable clamping.

[0009] (2) This utility model has several clamping isolation blocks arranged along the length direction of the rear support bar and the front support bar. A set of back-to-back first rocker arm plates and second rocker arm plates can be placed between any adjacent clamping isolation blocks, so that the operator can quickly switch to weld the set of first rocker arm plates and second rocker arm plates, which has extremely high operating efficiency.

[0010] In summary, this utility model has the advantages of simple structure, reliable clamping, and efficient and reliable welding, and has high practical and promotional value in the field of electric garbage truck production technology. Attached Figure Description

[0024] like Figures 4 to 5 As shown, this embodiment provides a welding fixture for a lever brake rocker arm of an electric garbage truck, which clamps a first rocker arm plate 210 and a second rocker arm plate 220. Here, the first rocker arm plate 210 and the second rocker arm plate 220 are back-to-back to form a Y shape. The first rocker arm plate 210 and the second rocker arm plate 220 have the same structure, and the first rocker arm plate 210 includes a rotating shaft connecting end 211, an arc-shaped end 212, and a crank arm connecting end 213 connected in sequence.

[0025] In this embodiment, the welding fixture for the lever brake rocker arm of the electric garbage truck includes a lower support block 1, a rear support bar 2 and a front support bar 3 fixed to the lower support block 1 and arranged perpendicularly to each other, and several clamping isolation blocks 4 fixed to the rear support bar 2 and the front support bar 3 and arranged along the length direction of the rear support bar 2 and the front support bar 3. The clamping isolation blocks 4 are evenly spaced, and the distance between adjacent clamping isolation blocks 4 is equal to twice the thickness of the pivot connection end 211. Here, the pivot connection end 211 of the first rocker arm plate 210 and the pivot connection end 211 of the second rocker arm plate 220 are placed between adjacent clamping isolation blocks 4. Furthermore, the clamping isolation blocks 4 are right-angled trapezoidal in shape. It should be noted that the lower support block 1 is fixed to a workbench surface (not shown). In addition, the first rocker arm plate 210 and the second rocker arm plate 220 between adjacent clamping isolation blocks 4 are arranged in a horizontal direction; or, the end where the crank arm connecting end 213 is located is higher than the end where the rotating shaft connecting end 211 is located, so as to ensure that the first rocker arm plate 210 and the second rocker arm plate 220 are limited between the clamping isolation blocks 4, which also facilitates the operation of welding personnel.

[0026] In use, the first rocker arm plate 210 and the second rocker arm plate 220 are arranged back to back, with the pivot connection end 211 of the first rocker arm plate 210 and the pivot connection end 211 of the second rocker arm plate 220 attached together. The pivot connection ends 211 of the first rocker arm plate 210 and the second rocker arm plate 220 are placed between adjacent clamping isolation blocks 4. In this way, several or dozens of sets of first rocker arm plates 210 and second rocker arm plates 220 can be placed. The welding operator welds the back-to-back arranged first rocker arm plates 210 and second rocker arm plates 220 in sequence. After all the first rocker arm plates 210 and second rocker arm plates 220 are welded on the same side, all the first rocker arm plates 210 and second rocker arm plates 220 can be flipped over and the other side can be welded. The welding operation is highly efficient.

[0027] The above embodiments are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any changes made based on the design principles of this utility model, or any non-creative changes made on this basis, shall fall within the scope of protection of this utility model.
