For achieving the above object, a kind of anchor clamps of turning corrugated pipe connector comprise fixed disk; On the central shaft position of fixed disk, the axis of guide is installed; Being provided with the fixed disk central shaft on the fixed disk front end face is the slide block more than two that radially slides that the center of circle is being uniformly distributed with on the circumference; The arc supporter is installed on each slide block, and it is on the same circumference in the center of circle that the outer circumference surface of the arc supporter on each slide block is in the fixed disk central shaft; Be with taper sheath on the described axis of guide.
Above-mentioned anchor clamps; Through moving axially taper sheath; Each slide block can be on the front end face of fixed disk is radially motion simultaneously of the center of circle with the fixed disk central shaft, thereby regulates the radial motion simultaneously of arc supporter, with the installation and removal of the corrugated pipe connector stock that is fit to the different tube diameters size.Owing to be provided with supporter; When the corrugated pipe connector stock is installed, the corrugated pipe connector stock is installed on the supporter and can processes, so just can overcome unsettled defective is installed on chuck; Make that the stable installation property of corrugated pipe connector stock is good, produce safety.
As improvement, the rear end face of taper sheath is connected with cylindrical sleeve, and cylindrical sleeve is enclosed within on the axis of guide, is formed with containing cavity between the inner peripheral surface of cylindrical sleeve and the axis of guide; The leading section of the axis of guide is provided with screw thread, and at the leading section of the axis of guide rotation loop bar that has been threaded, the rearward end outer circumference surface outward radial of rotation loop bar is extended with flange; Be provided with two thrust ball bearings in the described containing cavity, be formed with the gap between two thrust ball bearings; Described flange places in the gap.This structure is used to move axially taper sheath, and its process is: rotation rotation loop bar, and the rotation loop bar is with respect to axis of guide axially-movable; The rotation loop bar is in motion process; Flange drives cylindrical sleeve and taper sheath axially-movable, thereby reaches the purpose that moves taper sheath, the position of the adjustment supporter that this structure can not only be manual; Be convenient to clamping corrugated pipe connector stock, and simple in structure.Said structure, owing to be provided with thrust ball bearing, therefore, when the rotation of rotation loop bar, taper sheath will not followed the rotation of rotation loop bar.
As improvement, be provided with patchhole radially to the instrument insertion at the leading section that rotates loop bar.Like this, be convenient to setting tool, help rotation rotation loop bar.
As improvement, between slide block and taper sheath, be provided with roller on the slide block.After roller is set, become rolling friction by sliding friction between slide block and the taper sheath, thereby reduced the resistance of motion of taper sheath; And avoided the wearing and tearing of slide block, simultaneously, behind rolling wheel wear; Need not change slide block, only need to change roller and get final product, reduce maintenance cost.
As improvement, the central shaft position that on fixed disk, is positioned at fixed disk is equipped with the lead that extends to the fixed disk rear end.This structure, when being installed to fixed disk on the chuck, lead has the guide-localization effect, the axiality between the central axis of raising fixed disk and the central axis of chuck, thereby the machining accuracy of raising parts.
As improvement, the arc supporter comprises skeleton body and arcuate member, and arcuate member is located on the skeleton body, and described skeleton body is a hollow structure.The skeleton physical efficiency that is designed to hollow structure alleviates the weight of whole supporter, can reduce consumptive material simultaneously, reduces the manufacturing cost of special fixture.
As improvement, be provided with the reinforcement gusset between slide block and the skeleton body.This structure can improve the bonding strength between slide block and the skeleton body, simultaneously, can improve the radially bearing capacity of supporter.
