Problems solved by technology

[0005] 3. Track spreading and track assembly are in the same position, which affects the assembly cycle
[0006] 4. After the track is spread out, there is generally no positioning device, which cannot guarantee the straightness of the track after it is spread out.
As far as the domestic construction machinery excavator manufacturing industry is concerned, there is no automatic assembly equipment for excavator tracks

Embodiment 1

[0040] Such as Figure 1-3 As shown, the excavator crawler automatic assembly equipment in this embodiment includes: a shuttle car 5 with a lifting structure, which walks on the assembly station line 11 and is used to carry the lower frame assembly 9; a conveyor 4, transporting the crawler belt 10 To both sides of the assembly station line 11, the transportation direction is perpendicular to the assembly station line 11, and the conveyor adopts an electric cart powered by a low-voltage rail; the uncoiler 3 is located on both sides of the assembly station line 11 and lifts the crawler 10 is flattened or wrapped; spreading platform 12 is located on both sides of assembly station line 11 and carries crawlers 10 in a flattened shape; rail chain pin pressing machine (not shown), presses crawler belts 10 and rail chains are connected , and the conveyor 4 is provided with a double station corresponding to the spreading platform 12 on both sides of the assembly station line 11 and use...

Embodiment 2

[0055] The difference between this embodiment and the first embodiment is that it further includes a pusher 2 arranged on the spreading platform 12 and pushing the flattened track to the wrapping position. Like this, utilize pushing machine to be able to guarantee that the caterpillar belt that is flattened on the spreading platform is adjusted to straight line, and is positioned at the crawler belt assembly position of lower vehicle frame assembly just below, is conducive to crawler belt assembly. In order to further ensure the straightness of the track, hydraulic cylinders, air cylinders or electro-hydraulic push rods with synchronous valves can be used for the power components of multiple pushers to facilitate the effective calibration of the track; There is a positioning belt on the side, so that the crawler can be accurately positioned at the position to be wrapped and ensure the straightness of the pushed crawler.

[0056] The assembly method of this scheme can generally...

Embodiment 3

[0058] The difference between this embodiment and the above-mentioned embodiment is that the elevators 1 located on both sides of the assembly station line 11 and directly below the assembly positions of the crawler belts 10 on both sides of the lower frame assembly 19 are used to replace the elevators 1 of the shuttle car 5. structure. In this way, without lifting or lowering the lower frame assembly through the lifting function of the shuttle car, the crawler belt can be raised to the assembly position through the lifting of the elevator, so that the unwinder can wrap the crawler belt on the lower frame assembly assembly.

[0059] The upper plane of the elevator 1 in this embodiment is flush with the upper surface of the spreading platform 12 when it is not jacked up, which does not affect the flattening of the caterpillar belt by the unwinding machine on the spreading platform or interferes with the work of the pusher.

[0060] The power components of the plurality of elev...

Abstract

The invention discloses automatic assembly equipment and method for an excavator caterpillar band, which belongs to the technical field of factory automatic assembly and is used for implementing automatic assembly of the caterpillar band at the two sides of a lower frame assembly of an excavator. The assembly equipment comprises a shuttle bus which travels on an assembly station line, is used forbearing the lower frame assembly and is provided with a lifting structure, a conveyor which conveys the caterpillar band to the two sides of the assembly station line, unrolling-rolling machines whichare arranged at the two sides of the assembly station line and are used for hoisting and conveying the caterpillar band to be in an unrolled state or a rolled state, a spreading table which is used for bearing the unrolled caterpillar band, a track chain pin pressing machine for pressing the rolled caterpillar band, and a pushing machine for pushing the unrolled caterpillar band to a rolling position. The automatic assembly equipment realizes fully-automatic assembly between the lower frame assembly of the excavator and a caterpillar band part, and fills up the blank of caterpillar band automatic assembly of engineering machinery excavator manufacturing enterprises in China.

Description

technical field [0001] The invention belongs to the technical field of factory automation assembly, and in particular relates to an excavator crawler automatic assembly equipment and an assembly method thereof. Background technique [0002] In the machinery industry, excavators are known as the "Pearl in the Crown" of construction machinery products, and the crawler is a key component of the lower frame assembly of the excavator. The crawler assembly process is an extremely important and critical part of the excavator assembly process. . At present, there is no equipment in our country that can automatically assemble the above-mentioned excavator crawler parts and directly transfer them between upstream and downstream stations. At present, the main operation methods of mainstream manufacturers are as follows: [0003] 1. The upper part of the track roll is put in place by manually operating a forklift or driving. [0004] 2. The spreading of the crawler roll is realized b...
