Description

Technical Field

[0001] This utility model relates to the field of engineering machinery technology, and in particular to a set of tooling and assembly device. Background Technology

[0002] See Figure 8 The lower mechanism of a split excavator typically consists of three parts: two track beam assemblies (16) and one underframe assembly (15). The track beam assembly (16) and the underframe assembly (15) are connected by bolts (18). When assembling the lower mechanism, two triangular support frame fixtures (17) (with a height lower than the height of the underframe after assembly) need to be prepared. First, one track beam assembly (16) is initially positioned. Then, the underframe assembly (15) is hoisted to the top of the track beam assembly (16) using a crane. The holes are manually aligned and bolts (18) are pre-installed using a pry bar. After completion, the underframe assembly (15) is suspended in the air. Two triangular support frame fixtures (17) need to be placed under the underframe assembly (15) for support. Polyurethane pads are added to the triangular support frame fixtures (17) according to the height of different models to solve the height difference problem. Finally, the other track assembly is slowly hoisted under the underframe assembly (15) and the holes are aligned and bolts are pre-installed.

[0003] The shortcomings of the existing technology are: the assembly process of the underframe and track beam requires multiple people to work together, the operation is cumbersome and complicated, there are safety risks in assembling while hoisting, and the underframe hole alignment relies entirely on manual use of pry bars, which is labor-intensive, does not conform to ergonomics, and has low assembly efficiency.

[0015] In summary, the technical solution of this utility model has the following beneficial effects: The structure of this utility model is reasonable. (1) By setting two support rails distributed along the front and back, the length of the two support rails extends along the left and right. The base, rotating plate and working platform are arranged in sequence above the two support rails. The edge of the base is provided with a walking mechanism, which includes several rollers and a first motor. The first motor is used to drive the rollers to rotate. The front and rear edges of the base are respectively cooperated with the two support rails through the rollers. The rollers can carry the base, rotating plate and working platform to move back and forth along the support rails in sequence. Thus, when the track beam assembly 16 is placed on the working platform, once the rollers are driven by the first motor, the rollers can carry the base, rotating plate, working platform and track beam assembly 16 to move back and forth along the support rails in sequence. (2) A rotary mechanism is provided between the middle of the base and the middle of the rotating plate. The rotary mechanism can drive the rotating plate and the working platform to rotate relative to the base in sequence. Several slide rail structures and a transverse movement mechanism are provided between the rotating plate and the working platform. The length of the slide rail structure is parallel to the length direction of the rotating plate and the working platform. The transverse movement mechanism can drive the working platform to move back and forth along the slide rail structure relative to the rotating plate. Thus, the rotary mechanism can be used to drive the rotating plate to rotate relative to the base, and then the rotating plate can be used to drive the working platform and the track beam assembly 16 to rotate accordingly in sequence. At the same time, the transverse movement mechanism can be used to drive the working platform to move back and forth along the slide rail structure, and then the working platform can be used to drive the track beam assembly 16 to move back and forth. Thus, in actual use, the following operation steps can be referred to: (1) Distribute the two sets of tooling 14 on the left and right sides, leaving space between the two sets of tooling 14 for the AGV handling robot 13 to enter and exit. (2) Use a crane to lift the left and right track beam assemblies 16 onto the working platform 4 of the two sets of tooling 14 and place them in the preset position. (3) Use a crane to lift the base frame assembly 15 onto the AGV transport robot 13. (4) The AGV transport robot 13 transfers the base frame assembly 15 between the two assembly tooling units 14 and lifts it to the specified height. (5) The two assembly tooling units 14 move the left and right track beam assemblies 16 to the required positions. That is, under the drive of the traveling mechanism, the two assembly tooling units 14 move the left and right track beam assemblies 16 closer to each other and further away from each other in the left and right directions, thereby adjusting the positional relationship between the track beam assembly 16 and the base frame assembly 15 in the left and right directions. And under the drive of the slewing mechanism, the left and right track beam assemblies 16 rotate, thereby adjusting the positional relationship between the track beam assembly 16 and the base frame assembly 15 in terms of rotation angle. And under the drive of the lateral movement mechanism, the left and right track beam assemblies 16 are moved laterally in the front and rear directions, thereby adjusting the positional relationship between the track beam assembly 16 and the underframe assembly 15 in the front and rear directions, so as to finally achieve the alignment between the track beam assembly 16 and the underframe assembly 15. (6) Install the corresponding bolts 18 at the alignment position.As can be seen from the above analysis, this utility model eliminates the need for multiple people to work together, greatly reduces the intensity of manual labor, improves ergonomics, and significantly increases the assembly efficiency of the track beam assembly and the underframe assembly.
