Description

Technical Field

[0001] The utility model relates to the technical field of heavy-duty felling machines, in particular to a tool for eliminating assembly interference of a drive cover of a heavy-duty felling machine. Background Art

[0002] In the structure of a heavy-duty felling machine, the drive housing is assembled with the housing cover plate and the track plate to provide physical protection for the drive of the heavy-duty felling machine and prevent foreign matter from entering the interior of the drive, thereby protecting the normal operation of the drive. At the same time, the housing can also withstand external shocks and vibrations to reduce the risk of damage to the drive. Therefore, during the assembly process of the heavy-duty felling machine, the relevant matching accuracy between the drive housing and the housing cover plate is required to be very high.

[0003] In the actual production process, since the driver cover of the heavy-duty felling machine is a semi-circular special-shaped structure, the driver cover needs to undergo multiple continuous welding to be completed. However, during the welding process, the driver cover of the heavy-duty felling machine is affected by the welding stress, which will cause two major deformations after welding: on the one hand, the opposite side of the track surface group will appear tilted toward the driver side, and on the other hand, the single-sided welding of the semi-circular plate will shrink and deform inward, which will directly affect the assembly of the driver cover and the use of the product.

[0004] In the prior art, there is no dedicated tooling for eliminating assembly interference in the welding production of the driver cover of a heavy-duty felling machine, so that it takes a lot of time to adjust the deformation of the driver cover after welding, which is time-consuming and labor-intensive, and cannot ensure uniform product quality. Utility Model Content

[0007] Preferably, a heavy-duty felling machine drive cover is placed by coordinated positioning of the positioning platform, the positioning device, the first support seat, the second support seat, and the top screw.

[0008] Preferably, the second support seat structure is the same as that of the first support seat, and is arranged close to the right end of the positioning platform.

[0009] Preferably, the top screw positions and fixes the left end bottom of the heavy-duty feller driver cover.

[0010] Compared with the prior art, the beneficial effects of the utility model are:
