Description

Technical Field

[0001] This utility model relates to an excavator boom assembly, and more specifically, to a tooling platform for excavator boom assembly. Background Technology

[0002] The boom and stick refer to a working device on an excavator, also commonly called the boom and arm. Their main function is to control the digging and loading actions of the bucket. The arm connected to the frame is longer, hence the common name "boom," and its technical term is boom; the arm connected to the bucket is shorter, hence the common name "arm," and its technical term is stick. Therefore, they are commonly referred to as the boom and arm.

[0003] Multiple devices are installed on the stick for combination, such as multiple hydraulic pipe joints or sensors, to facilitate the connection between the stick, boom, and hydraulic mechanism.

[0004] When assembling the boom, various equipment structures need to be combined and installed. However, the boom is large in size and weight, making it inconvenient to rotate and adjust, which makes the assembly process very troublesome and inconvenient. Utility Model Content

[0007] Preferably, the first clamp, the second clamp, and the third clamp all include a threaded rod threadedly connected to the mounting frame, and one end of the threaded rod is movably connected to a clamping plate located inside the mounting frame.

[0008] Preferably, a limiting ring is fixedly provided at the other end of the threaded rod, and a hexagonal screw hole is provided in the middle of the limiting ring and the threaded rod.

[0009] Preferably, the external toothed ring has sliding ring grooves on both sides, and the external toothed ring has retaining rings on both sides. A sliding ring is fixedly provided on the inner side of the retaining ring, and the sliding ring is movably located inside the sliding ring groove.

[0010] Preferably, a closing ring is fixedly provided on the outer side of the retaining ring, and the external gear ring and the gear are movably positioned between the retaining ring and the closing ring.

[0011] Preferably, the retaining ring is welded to the outside of the gear with a mounting plate, and the servo motor is fixedly mounted on the mounting plate.

[0012] Preferably, a plurality of support legs are welded to the lower part of the closed ring, the bottom ends of the plurality of support legs are welded together to a base, and a reinforcing rod is welded between the plurality of support legs.

[0013] According to one embodiment of this disclosure, the assembly tooling platform drives the external gear ring to rotate via a gear on a servo motor, and a roller shaft, a first clamp, a second clamp, and a third clamp are installed inside the external gear ring via a mounting bracket. When installing the boom, the boom is pushed by the roller shaft to facilitate position adjustment, and the boom is clamped and fixed by the first clamp, the second clamp, and the third clamp to maintain the stability of the boom.

[0014] The servo motor drives the external gear ring to rotate, which in turn flips the internal boom. This facilitates the installation and connection of hydraulic nozzles, sensors, and other equipment structures at different positions on the boom, making it easier for operators to install and connect the structures and improving the convenience of assembly operations.

[0015] Furthermore, multiple first and second platforms are combined and installed to facilitate support of the boom and maintain its balance and stability.
