Technical Field
[0001] The present invention relates to the field of automobile technology, in particular to a gantry lever for tightening tools in the new energy automobile assembly industry. Background Art
[0002] New energy vehicles refer to vehicles that use unconventional automotive fuels as their power source (or use conventional automotive fuels and adopt new on-board power devices), and integrate advanced technologies in vehicle power control and drive to form automobiles with advanced technical principles, new technologies, and new structures. In the mass-produced automobile assembly, in order to improve labor productivity, assembly quality and automation level, and minimize the assembly labor on the assembly line, so as to avoid the trouble caused by the long assembly line in logistics (parts to be assembled) transportation, some parts are pre-assembled outside the line as much as possible to form their own independent assembly units and various modules, and then the automobile is assembled. When assembling automobile parts, the assembly of related tightening structures and auxiliary parts is required.
[0003] When assembling automobile parts, the surface of the parts often needs to be trimmed. The unevenness on the outer surface of the automobile assembly parts can be polished to turn the defective automobile assembly parts into usable automobile assembly parts. However, some surface treatment devices for the production of finished automobile assembly parts do not have a device for adjusting the position of the triangular friction. When in use, it is impossible to accurately polish the protruding parts on the outer surface of the automobile assembly parts, and it is impossible to accurately repair them. For this reason, the present application now proposes a gantry force arm for tightening tools in the new energy automobile assembly industry, which can assist in polishing the surface of automobile assembly parts.

[0028] Working principle: A gantry arm for tightening tools in the new energy vehicle assembly industry. When in use, the gantry arm frame is installed in the designated position. First, take the automobile assembly part in your hand, find the part that needs to be trimmed, and turn on the switch of the motor 32. When the motor 32 starts running, the gear 31 can be rotated. When the gear 31 starts rotating, the friction belt 36 can be transmitted. When the friction belt 36 is transmitted, the first rotating rod 34 and the second rotating rod 35 can be transmitted, so that the automobile assembly part rubs on the outer surface of the friction belt 36, and the excess part of the outer surface of the automobile assembly part can be removed. When the outer surface of the automobile assembly part protrudes more obviously, the two pressure blocks 21 can be clamped internally.

The clamping block 14 clamps the pressure block 21 inside, and the right side of the clamping block 14 is fixedly connected When the first and second plates 6 and 8 are tightened, the elastic steel strip contracts, so that the protrusion 9 is no longer engaged with the inside of the anti-slip groove, so that the first and second plates 6 and 8 can move up and down with the pull rope 5, so that the pull rope 5 can slide on the outer surface of the movable shell 4, thereby making the connecting block 12 slide up and down. When the connecting block 12 slides up and down, the clamping block 14 can slide up and down, and the friction belt 36 can be moved up and down. The staff can adjust the upper and lower parts of the friction automobile assembly parts to reduce the damage to the staff's wrists. When the height is adjusted to a suitable height, the first and second plates 6 and 8 can be loosened, so that the elastic steel strip rebounds, and the protrusion 9 is engaged with the inside of the anti-slip groove, keeping the pull rope 5 fixed, so that the position of the clamping block 14 is fixed, and grinding at different heights can be performed. The gantry force arm for tightening tools in the assembly industry has multiple functions, is easy to use and can improve product quality.
