Description
Technical Field
The utility model relates to a straining device especially relates to a vacuum box assembly line straining device.
Background
The existing standardized assembly line is not specially designed for narrow space, and when the traditional assembly line is installed in narrow space such as a vacuum box, the adjusting mechanism is generally designed at two ends of the assembly line. Some small vacuum boxes can only be inserted into one hand for debugging operation, and if maintenance and adjustment are required, the assembly line is completely disassembled, then the assembly line is taken out of the vacuum box for adjustment, and then the assembly line is installed in the vacuum box again. Therefore, when a standardized assembly line is used as a carrying device of a workpiece in the full-automatic vacuum box, the tensioning mechanism of the assembly line is difficult to adjust, and the working efficiency is low; therefore, the space of the box body has to be enlarged, the box body becomes large, and the problems of low vacuum-pumping efficiency, heavy vacuum box body, low productivity, slow rhythm and the like can be caused.
Disclosure of Invention
The utility model discloses to the technical problem of the inconvenient adjustment of current vacuum box assembly line straining device, provide a vacuum box assembly line straining device convenient to adjustment.
Therefore, the technical scheme of the utility model is that the device comprises a gear meshed with the chain of the assembly line, a connecting shaft of the gear is connected with a sliding block, the rear end of the sliding block is connected with a tensioning bolt in a threaded manner, the other end of the tensioning bolt is connected with a tensioning thumb wheel, and the tensioning thumb wheel is connected with an automatic locking device; the side cover of the production line is provided with a slideway matched with the slide block.
Preferably, the tensioning thumb wheel is circumferentially provided with a plurality of thumb holes.
Preferably, the tensioning bolt is provided with a circular boss, the assembly line shell is fixedly connected with a supporting seat for supporting the tensioning bolt, and the supporting seat is provided with a notch matched with the circular boss.
Preferably, the output shaft of the automatic locking device is a special-shaped shaft, and the tensioning thumb wheel is provided with a special-shaped hole matched with the special-shaped shaft.
Preferably, the automatic locking device is a two-way ratchet mechanism.
Preferably, the pipeline side cover is provided with an operation opening at a position corresponding to the tensioning thumb wheel.
The beneficial effects of the utility model, the side part is removed to the tensioning power mechanism at assembly line both ends originally, through rotating the tensioning thumb wheel, realizes the control to the gear position, and the dead tensioning impeller of automatic locking device lock of rethread. In narrow and small space, the assembly line in the vacuum box does not need to be disassembled, the tension of the assembly line can be adjusted, and the working efficiency is improved.
