Abstract
A band saw tensioning structure relates to a band saw part which comprises a tensioning seat fixed on a frame and a swinging arm arranged on the tensioning seat; a saw axle is arranged on the swinging arm, an adjusting rod which is connected with the swinging arm and is used for adjusting the swing amplitude of the swinging arm is arranged on the frame, wherein, the swinging arm is a structure with two parallel pendulum shafts; the end of the pendulum shaft is provided with a permanent seat; a slide block is arranged between the permanent seat of the pendulum shaft and the tensioning seat; the saw axle is arranged on the slide block; an adjusting screw connected with the slide block is arranged on the permanent seat; the slide block is provided with an offsetting spring which can not only achieve the adjustment of the sawblade in a larger scale but also achieve vernier adjustment on the basis and prevent deflection.
Description
Technical field:
These practical parts that relate to a kind of band saw are a kind of band saw Tensioning structure specifically.
Background technology:
Band saw is widely used in activity in production, as one Tensioning structure of the important structure in the band saw, realization is to the adjusting of saw blade tension force, it is the indispensable part of band saw, the kind of Tensioning structure is more now, wherein commonly used a kind of be the arm-type Tensioning structure of single pendulum, the saw wheel axle is arranged in the swing arm, the adjusting of the amplitude of oscillation by swing arm realizes the adjusting of saw blade tension force, this kind structure is comparatively simple, operate more convenient, but because the amplitude of oscillation that swing arm produces in mediation process is bigger, and therefore suitable adjusting by a relatively large margin should not be frequently regulated in swing arm after fixing, fine setting for saw blade tension force is not easy to realize that the simple pendulum arm structure causes beat easily owing to be subjected to the effect of increased force will in use on the other hand.
Summary of the invention
The purpose of this utility model is to provide a kind of swing arm novel band saw tension mechanism at the deficiency of existing band saw existence.
In order to realize goal of the invention, the utility model band saw Tensioning structure is achieved by the following scheme:
A kind of band saw tension mechanism is the swing arm Tensioning structure.Comprise the tension base that is fixed on the frame, tension base is provided with swing arm, and swing arm can be swung around tension base, and swing arm is provided with the saw wheel axle, and saw wheel is located on the saw wheel axle with the same moved further of swing arm.Frame is provided with the adjusting rod that is connected with swing arm, and adjusting rod passes frame and is connected with swing arm, regulates the amplitude of oscillation of swing arm when tension base is swung, and described swing arm is two parallel balance staff structures, and balance staff one end is provided with on the tension base, swings synchronously around tension base.Be provided with holder in two balance staff the other end, be provided with slide block between balance staff upper fixed seat and the tension base, slide block can slide up and down along two balance staffs.The saw wheel axle is arranged on the slide block, slides with slide block.Holder is provided with adjusting screw(rod), passes holder and is connected with slide block, the sliding distance of adjusting slider.Slide block is provided with back-moving spring, and slide block is exerted pressure to axle head along balance staff.
In order to realize the purpose of this invention better, aforesaid band saw tension mechanism, the parallel riffled tube that is provided with balance staff on the slide block, adjusting screw(rod) is connected with riffled tube, by the clockwise or counterclockwise turn of adjusting screw(rod), pulling or promote slide block and slide.
In order to realize the purpose of this invention better, aforesaid band saw tension mechanism is provided with fixed mount between balance staff upper fixed seat and the slide block, and back-moving spring is arranged between fixed mount and the slide block, is sleeved on the peripheral pressed slider of adjusting screw(rod).
Foregoing band saw tension mechanism, described back-moving spring can also be sleeved on the balance staff, and two balance staffs are respectively equipped with the spring compression slide block.
Aforesaid band saw tension mechanism, described balance staff adjusting rod is connected with holder.
The beneficial effects of the utility model are: can either realize the adjusting in a big way of saw blade, realize again on this basis fine setting preventing beat simultaneously.
