Description
Technical field
The utility model relates to a kind of swelling device.
Background technology
The current swelling device that chain divides wiring to use that pushes away at auto assembly workshop vehicle frame, the structure of swelling device as shown in accompanying drawing 1, this swelling device is generally arranged on a side of flower wheel, the transmission shaft that is flower wheel is rotatably connected in bearing seat, bearing seat horizontal slip is connected on bracing frame, by screw mandrel, drive bearing seat to move forward and backward, thereby driving band or transmission chain are carried out to tensioner, and the shortcoming of this structure is: exist process trolley return rail install inconvenience, error large, adjust difficulty, the not smooth problem of whole line operation.
Utility model content
The utility model provides a kind of adjustment simple and accurate swelling device for the problems referred to above.
In order to solve the problems of the technologies described above, the utility model provides a kind of swelling device of following structure, it comprises tensioner frame, its constructional feature is: in tensioner frame, slidably connect the adjustment rack sliding along tensioner stands longitudinal, on adjustment rack, by bearing seat, horizontally set is installed and the rotating shaft of power wheel is installed, in tensioner frame, be rotatably connected to longitudinal setting and through the adjusting screw of adjustment rack, on adjustment rack, be connected with the adjusting nut being screwed onto on adjusting screw.
Two adjusting screws that laterally be arranged in parallel are set in described tensioner frame, and the front and rear of adjustment rack is connected with respectively the adjusting nut being screwed onto on adjusting screw.
Described tensioner frame both lateral sides is respectively equipped with the longitudinal rail of longitudinal setting, and the both lateral sides of adjustment rack is respectively equipped with at least two hold-down arms, and horizontal roller and vertical roller that longitudinally guide rail rolls are housed on each hold-down arm.
On described adjustment rack, bracing frame is housed, on bracing frame, is connected with the chain guide that guarantees chain operation.
Adopt after said structure, thereby the swelling device that the utility model provides is rotated and is driven adjustment rack to move forward and backward by adjusting screw, and then drive installation has the rotating shaft of drive wheel to move forward and backward, realize tensioner effect, adopt the swelling device of said structure can make adjustment more flexible, reduce and install and the error of adjusting, make tensioner adjustment more accurate, effectively prevent the unbalanced phenomenon of tensioner, guaranteed the smooth and easy operation of whole piece conveyor line.And the end, front and back that two adjusting screws and adjustment rack are set arranges adjusting nut, can make in tensioner adjustment process more steady, straightness accuracy and parallelism when the horizontal roller arranging and vertical roller can effectively guarantee tensioner adjustment, be convenient to accurate adjustment tensioner degree, the swelling device of said structure is convenient to install bracing frame and chain guide, make whole piece conveyor line structure more reasonable, be specially adapted to the turning transhipment of the transportation tooling of swinging conveying.
In sum, the rotating shaft that the utility model can steadily be adjusted installation drive wheel realizes tensioner effect, has and adjusts simply and adjust accurate advantage.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail:
Fig. 1 is the structural representation of swelling device of the prior art;
Fig. 2 is the structural representation of a kind of embodiment of the utility model;
