The utility model content
In order to solve problem and the shortcoming that above-mentioned prior art exists, the purpose of this utility model provides a kind of adjustable eccentric turning attachment, it can be installed on lathe and be used to process the various different eccentric first-class parts of eccentric shaft, bent axle and T joint, and versatility is good, has reduced anchor clamps quantity.
For addressing the above problem, the utility model by the following technical solutions: this adjustable eccentric turning attachment, comprise connecing dish, clamp body, pull bar, described clamp body is fixed on and connects on the dish, an end of pull bar connects and starts oil cylinder; The other end of pull bar connects the mandrel of coaxial setting; Described clamp body is provided with inner chamber, is provided with a curved bar in the inner chamber, also is provided with a fulcrum shaft in the inner chamber, and described curved bar is installed on this fulcrum shaft and can rotates around this fulcrum shaft; One end and the mandrel of curved bar flexibly connect by spacer pin, and spacer pin is fixed on the mandrel, and the end of curved bar is provided with the inverted U-channel that cooperates connection with spacer pin; The inner chamber that the curved bar other end stretches out in clamp body is connected with clamp; The end face of clamp body is provided with groove, described clamp is positioned at this groove and cooperates for longitudinal sliding motion between the two, be connected with the pressing plate spacing to clamp on this end face of clamp body, also be provided with the locating piece corresponding with clamp in this groove, locating piece is positioned at the below of clamp; The corresponding locating groove that is provided with holding workpiece on the bottom surface of clamp and on the end face of locating piece.
As further technical scheme of the present utility model:
In these anchor clamps, be provided with the adjustment cushion block between the groove of described clamp body end face and the locating piece bottom surface.
In these anchor clamps, the locating groove on the described clamp is arc groove or v-depression.
In these anchor clamps, the locating groove on the described locating piece is arc groove or v-depression.
The beneficial effects of the utility model are: when being used in the first-class part of processing various different eccentric eccentric shaft, bent axle and T joints on lathe, the adjustment cushion block that only needs to change different-thickness according to the part needs gets final product, the anchor clamps versatility is good, adjust easily, easy to operate, the processing parts precision is good, and significantly reduces the input of special fixture, economizes on the use of funds.
