Wherein, be provided with the technology cover at the plane contact place of the claw upper holder block of spring chuck body.
Wherein, described claw and locating shaft are three, and three claws outwards open, are bell mouth shape.
Wherein, three claws and three locating shafts are provided with at interval, and the angle between each claw and the locating shaft is 60 °.
The utility model operation principle is: pull bar is connected with the hydraulic cylinder piston rod at lathe spindle rear portion, driven plunger in the pressure oil input hydraulic pressure oil cylinder that provides by hydraulic power unit, the drive pull bar moves, make the spring chuck body produce strain, thereby inwardly drive briquetting and the little toothed surface of pushing down part tightly.
Beneficial effect: the anchor clamps that are used for the positioning and clamping of profiled parts on the lathe described in the utility model have the following advantages: the first, this clamp structure is simple, reliable, and required pressure oil can obtain from the hydraulic system of lathe.The second, determine the shape and size of briquetting in the anchor clamps and little axle according to the dissimilar tooth form of part, applied widely, alleviated labor intensity of operating personnel, shortened the non-cutting time of part processing, improved operating efficiency, be convenient to realize automation.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment:
As shown in Figure 1, 2, the anchor clamps that are used for the positioning and clamping of profiled parts on the lathe described in the utility model, it comprises: pull bar 1, flange bolt 2, locating shaft 3, adpting flange 4, bolt 5, spring washer 6, nut 7, spring chuck body 8, technology cover 9, little cover 10, screw 11, briquetting 12, little axle 13.Pull bar 1 is arranged in the inner chamber of lathe spindle, and the left end of pull bar 1 is connected with the hydraulic cylinder piston rod at lathe spindle rear portion, and right-hand member is connected with spring chuck body 8.Spring chuck body 8 comprises a disc-shaped body, is provided with projection at the circumference and the center of the one side of body, and the projection center is provided with the through hole that connects body; The right-hand member of pull bar 1 is provided with screw thread, and pull bar 1 is fixing by nut 7 with the center projection.The peripheral projection of body is fixedlyed connected by bolt 5 with adpting flange 4.Described spring chuck body 8 adopts spring steel to make, and both can guarantee its strain, can normally use again.Adpting flange 4 is fixed on the lathe spindle.Outside oblique three claws that extend of the another side of body are fixed with briquetting 12 in the end of claw by screw 11.The one side of briquetting 12 is the plane, and another side is stepped ramp type, is provided with through hole at high step surface and low step surface intersection, is provided with little axle 13 in the through hole, and little axle 13 is outer also to be arranged with little cover 10, and wherein, little axle 13 flushes with high step surface, and little cover 10 flushes with low step surface.
Be provided with technology cover 9 at the plane contact place of the claw upper holder block 12 of spring chuck body 8, technology cover 9 can on the lathe from car spring chuck body 8 in hole dimension reliable with the clamping of assurance profiled parts 14.
Bolting at adpting flange 4 has locating shaft 3, and an end of locating shaft 3 passes the body of spring chuck body 8.Evenly be furnished with 3 pairs of profiled parts of 3, three locating shafts of three locating shafts at the circumference of adpting flange 4 and spring chuck body 8 and carry out axial location.In order to guarantee the reliable axial location of part, the end face of locating shaft 3 can be repaiied system.
