Abstract
The utility model discloses a cross shaft rotating and machining fixture, which comprises a rotating device and a clamping device. The rotating device comprises a first support, a rotating shaft, a rotating disk, a positioning disk and a clamping jaw of a hollow cylindrical structure, four clamp slots matched with a cross shaft are arranged on the wall of a cylinder, the positioning disk is fixed onto the first support, the rotating shaft is rotatably mounted on the first support, the rotating disk and the clamping jaw are fixed to two ends of the rotating shaft respectively, rotating holes are arranged on the rotating disk, springs and balls are mounted in the rotating holes, and grooves matched with the balls are arranged on the positioning disk. The cross shaft rotating and machining fixture is simple and reasonable in structure, convenient, rapid, high in precision and capable of driving the cross shaft to precisely rotate by 90 degrees by rotating the rotating disk.
Description
Technical field
The utility model relates to a kind of clamp for machining, particularly a kind of cross axle rotary processing anchor clamps.
Background technology
Cross axle is a vital part in the diesel locomotive power transmission shaft assembling universal coupling; The flatness of perpendicularity, symmetry and each axis of cross axle four axle journals requires very high, the balance and the service life of its processing precision direct influence universal coupling transmission.In order to guarantee crudy; Must make special-purpose cross axle anchor clamps; What the anchor clamps of the axis hole of existing cross axle processing adopted is with the working method that cross axle is fixed on the anchor clamps and manual swing cross axle changes Working position in process, and the waste of manpower in process of this cross axle clamp for machining, efficient are low.
The utility model content
The utility model technical problem to be solved is, overcomes the defective that prior art exists, and a kind of rotatable cross axle rotary processing anchor clamps of simple and reasonable, high efficiency are provided.
The utility model addresses the above problem the technical scheme that is adopted: these cross axle rotary processing anchor clamps; Comprise whirligig and clamping device, it is characterized in that: described whirligig comprises first support, rotating shaft, rotating disc, positioning disk and claw, and claw is to have four draw-in grooves that match with cross axle on hollow tube-shape structure and the barrel; Positioning disk is fixed on first support; Rotating shaft is rotatably installed on first support, and rotating disc and claw are separately fixed at the two ends of rotating shaft, has rotating hole on the rotating disc; Spring and ball are housed in the rotating hole, have four grooves that cooperate with ball on the positioning disk.
The described clamping device of the utility model comprises second support, motion bar and hydraulic cylinder, and hydraulic cylinder is fixed on second support, and motion bar is fixed on the piston rod of hydraulic cylinder.
Described first support of the utility model and positioning disk all are equipped with bearing, and rotating shaft is rotationally connected through the bearing on first support and the positioning disk and first support and positioning disk.
The utility model compared with prior art has the following advantages: simple and reasonable, and can drive cross axle through the rotation rotating disc and accurately revolve and turn 90 degrees, convenient and swift, precision is high.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the structural representation of the utility model embodiment whirligig.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Referring to Fig. 1～Fig. 2; Present embodiment comprises whirligig and clamping device, and described whirligig comprises first support 1, rotating shaft 2, rotating disc 3, positioning disk 4 and claw 5, and described claw 5 is for having four draw-in grooves that match with cross axle on hollow tube-shape structure and the barrel; Positioning disk 4 is fixed on first support 1; Be installed with clutch shaft bearing 6 in first support 1, be installed with second bearing 7 in the positioning disk 4, rotating shaft 2 is fixed with the inner ring of the clutch shaft bearing 6 and second bearing 7; Rotating disc 3 and claw 5 are separately fixed at the two ends of rotating shaft 2; Have a rotating hole on the rotating disc 3, spring 8 and ball 9 are housed in the rotating hole, have four grooves that cooperate with ball 9 on the positioning disk 4.
Clamping device comprises second support 10, motion bar 11 and hydraulic cylinder 12, and hydraulic cylinder 12 is fixed on second support 10, and motion bar 11 is fixed on the piston rod of hydraulic cylinder 12.
During use cross axle snapped in the draw-in groove of claw 5, primer fluid cylinder pressure 12 drives motion bars 11 and props up cross axle, thereby cross axle is fixed on the anchor clamps; Start process equipment processing cross axle, after the processing of accomplishing an axle journal, rotate rotating disk 3; Ball 9 leaves original groove; When ball 9 snapped in second groove, cross axle had just rotated 90 degree, can start the processing of process equipment to next axle journal; So carry out, just can conveniently realize the positioning of rotating in four axle journal process of cross axle.
Simple deformation of every the utility model or equivalent transformation should be thought the protection domain that falls into the utility model.
