Abstract

The utility model discloses a tensioning device. The tensioning device comprises a tensioning stander, wherein the tensioning stander is slidably connected with an adjusting frame which can slide along the longitudinal direction of the tensioning stander, the adjusting frame is provided with a rotating shaft through a bearing seat, the rotating shaft is provided with a transmission wheel, the tensioning stander is connected with a longitudinal adjusting lead screw in a rotating manner, the adjusting lead screw penetrates through the adjusting frame, and the adjusting frame is connected with an adjusting nut which is connected onto the adjusting lead screw in a screwing manner. By adopting the tensioning device, the rotating shaft with a drive wheel can be stably adjusted, so that the tensioning effect can be realized, and the tensioning device has the advantages of simplicity and precision in adjustment.

Description

A kind of swelling device

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;

Fig. 3 is the structural representation that Fig. 2 overlooks;

Fig. 4 is the structural representation that Fig. 2 left side is looked.

The specific embodiment

Swelling device of the prior art as shown in Figure 1, it comprises frame 20, in frame 20, horizontal slip is connected with bearing seat, between two relative bearing seats, be rotatably connected to axle drive shaft 21, axle drive shaft 21 is generally driven shaft, in frame 20, being also bolted with inner extending end leans lean leading screw 22 on bearing seat, by screwing, lean leading screw 22 and realize the front and back of bearing seat and slide, this mode leaning by single-point realizes tensioner, easily occur that tensioner pushes up inclined to one side phenomenon, and the swelling device of said structure is not easy to install chain road, thereby the chain that pushes away that is not suitable for auto assembly workshop vehicle frame divides wiring.

In the embodiment providing at Fig. 2 to Fig. 4, the chain that pushes away that is arranged on auto assembly workshop vehicle frame for this swelling device shown in figure divides the structure on wiring, swelling device provided by the utility model comprises tensioner frame 1, in tensioner frame 1, slidably connect along the adjustment rack 2 of tensioner frame 1 longitudinal sliding motion, on adjustment rack 2, by bearing seat, horizontally set is installed and the rotating shaft 3 of power wheel is installed, in tensioner frame 1, be rotatably connected to longitudinal setting and through the adjusting screw 4 of adjustment rack 2, on adjustment rack 2, be connected with the adjusting nut 5 being screwed onto on adjusting screw 4.Two adjusting screws that laterally be arranged in parallel 4 are set in tensioner frame 1, and the front and rear of adjustment rack 2 is connected with respectively the adjusting nut 5 being screwed onto on adjusting screw 4.Bracing frame 10 is housed on adjustment rack 2, on bracing frame 10, is connected with the chain guide 11 that guarantees that chain is turned and moved.

As shown in Figure 2 and Figure 4, for guaranteeing the accuracy rate of adjustment rack 2 front and back actions, tensioner frame 1 both lateral sides is respectively equipped with the longitudinal rail 6 of longitudinal setting, the both lateral sides of adjustment rack 2 is respectively equipped with at least two hold-down arms 7, horizontal roller 8 and vertical roller 9 that longitudinally guide rail rolls are housed on each hold-down arm 7, be that horizontal roller 8 leans on the interior facade of longitudinal rail 6, vertical roller 9 leans on the upper end face and bottom surface of longitudinal rail 6.

The above is specific constructive form of the present utility model; the utility model is not restricted to the described embodiments; the art personnel, the equivalent variations based on concrete structure on the utility model and parts are replaced all in protection domain of the present utility model.
