Problems solved by technology

However, this method ignores the relative position of the bonnet lock hook and the bonnet lock mechanism. There are currently two problems in this process scheme. It is not easy for the staff to judge the qualified condition of the gap flatness; second, after the assembly of the engine hatch lock with this process, it often occurs that the lock matching causes the gap flatness between the engine hatch and the fender to be out of tolerance

Embodiment 1

[0022] Such as figure 1 As shown, the bonnet installation tooling of this embodiment includes a body composed of two plates 9 arranged in parallel and a reinforcing beam 3 connecting the plates 9, a profiling lock mechanism 1 is installed between the two plates 9, each The same side of the plate 9 is equipped with a protruding reference block 2 of predetermined thickness and a positioning pin 5 that can be inserted into the positioning hole of the front beam of the body-in-white; The locking mechanism 4 that the front beam of the assembly is fixed.

[0023] The locking mechanism 4 is a manual clamp, and the free end of the manual clamp is equipped with a height-adjustable compression block 8. By adjusting the height of the compression block 8, the clamping force of the manual clamp can be adjusted. In order to adapt to different structures, the front beam of the engine compartment assembly of the body-in-white. The above is the standard part mechanism, you can choose Taiwan ...

Abstract

The invention discloses an engine hood installation tool and a using method thereof. By the adoption of the tool, during welding assembly of an engine hood, a worker can assemble the engine hood on a theoretical position stably and accurately, accurate relative positions of an engine hood latch hook and an engine hood lock mechanism are ensured, consistency of matching between the engine hood and a wheel fender is guaranteed, and the matching problem during subsequent final assembly is avoided. The engine hood installation tool is mainly composed of a body mechanism, wherein a profiling lock mechanism and a protruding reference block with a predetermined thickness are installed on one side of the body, a position pin is installed on the side, provided with the reference block, of the body and is capable of being inserted into a front beam positioning hole in a white body, and the body is further provided with a locking mechanism used for fixing the body and a white body engine compartment assembly front beam. The engine hood installation tool is simple in structure, small in size, low in weight, low in cost, convenient to use and highly practical.

Description

technical field [0001] The invention belongs to the technical field of welding mechanical equipment manufacturing, and in particular relates to an engine compartment cover installation tool and a use method thereof. Background technique [0002] The body-in-white of the cab is welded by hundreds of different sheet metal stamping parts. If the workmanship is poor and easy to deform, it is easy to cause problems in the matching quality of the body. The excessive assembly error of the body-in-white will not only directly affect the quality and performance of the vehicle, but also affect the appearance quality and sealing performance of the vehicle. The matching quality level of the body not only reflects the design level of the body, but also reflects the manufacturing level and management level of the manufacturer. The welding matching problem of the body-in-white is a comprehensive and intuitive manifestation of various manufacturing quality problems, and it is also a world...
