Abstract
The utility model discloses hinge type nipping fork of a shifting fork, which belongs to the technical field of machinery transmission. The utility model is formed by hinging a clamp body and a shifting lever by a shaft pin, a V-shaped slot type clamp loading hole and a fastening bolt with trapezoidal threads are arranged on the clamp body, a safety screw nail and a positioning hole are arranged on the shifting lever. The hinge type nipping fork not only can be used for clamping workpieces by matching with a shifting disc, but also can be used for clamping workpieces by matching with a long disc and can be used as a separate head for processing multiple threads. The hinge type nipping fork of a shifting fork has the advantages of convenient use, good versatility, big clamping force and little positioning error. The utility model is favorable to strong cutting and the improvement of cutting processing.
Description
The utility model relates to the heart carrier of machine cut clamping workpiece, belongs to the mechanical transmissioning technology field.
Existing heart carrier divides two kinds of straight tail formula and curved tail formulas, all be that common angular thread fastening bolt is set on collet body, and the clamping hole of chuck is the heart formula.Straight tail formula heart carrier is limited to and cooperates the clamping workpiece use with the dial that V-shaped groove is arranged, curved tail formula heart carrier is limited to and cooperates the clamping workpiece use with dial that driving lever is housed or chuck, universal performance is poor, because the clamping hole of chuck is the heart formula, fastening bolt is again common angular thread in addition, and is little to the clamping force of workpiece, easily produce position error, the bad phenomenon such as rotation of skidding influence the machining precision, or damage cutter and workpiece.
The purpose of this utility model is to provide a kind of by clamp body and the good hinge type shift fork heart carrier of the hinged versatility that constitutes of driving lever.
The purpose of this utility model is achieved in that hinge type shift fork heart carrier, by clamp body with driving lever is hinged constitutes, the clamping hole of clamp body is the V-shaped groove formula, radial slot is established in the front portion, be provided with by spring in the radial slot bottom, the steel ball positioner that steel ball, steel ball cover etc. constitute, fastening bolt adopts trapezoidal thread.The top of driving lever is provided with radial slot, and a sidewall of groove is provided with check screw, and the afterbody of driving lever is provided with locating hole, and the afterbody sleeve of driving lever adopts bearing pin to install and connects in the radial slot of clamp body front portion.
The utility model is rational in infrastructure, and manufacturing process is simple, and is easy to use, and versatility is good, both can cooperate clamping workpiece to use with dial, also can cooperate clamping workpiece to use with chuck, also can process multiple-threaded parted hair device and use.The clamping hole of chuck is the V-type slot type, and the error of clamping workpiece location is little, and clamping force is big, and the ability of bearing the external force effect is strong, is convenient to high-rate cutting processing, improves the machining quality.
Accompanying drawing 1 is the front view of the hinge type shift fork heart carrier that the utility model proposes, 1 clamp body among the figure, and 2 fastening bolts, 3 clamping holes, 4 pivot pins are rolled up with shelves for 5.
Accompanying drawing 2 is the side view of the hinge type shift fork heart carrier that the utility model proposes, 6 check screws, 7 driving levers among the figure, 8 ball positioners, 9 locating holes, 13 detents, 14 locating convex blocks.
Accompanying drawing 3 is the driving lever structural representation of the hinge type shift fork heart carrier that the utility model proposes, 6 check screws among the figure.
Accompanying drawing 4 is for the utility model proposes the steel ball positioning device structure schematic diagram of hinge type shift fork heart carrier, 9 locating holes, 10 steel balls, 11 springs, 12 steel ball covers among the figure.
Narrate a case study on implementation of the present utility model below in conjunction with accompanying drawing.
Hinge type shift fork heart carrier is connected with driving lever 7 usefulness pivot pins 4 by clamp body 1, and the pivot pin end is established axle and rolled up 5 with shelves, and the clamping hole 3 of clamp body 1 is the V-shaped groove formula, and fastening bolt adopts trapezoidal thread.Radial slot is established in the front portion of clamp body, and the bottom land middle part is provided with by spring 11, steel ball 10, and the steel ball positioner 8 that steel ball cover 12 constitutes, a side of bottom land is set position groove 13.Radial slot is established on the top of driving lever 7, establishes check screw 6 on the sidewall of groove, and the afterbody of driving lever 7 is established locating hole 9 and locating convex block 14.
When hinge type shift fork heart carrier cooperates clamping workpiece with dial, clamp body 1 and 7 one-tenth 180 ° of driving levers, the center on same axis, the detent 13 corresponding location that cooperate on locating hole 9 on the steel ball positioner 8 on the clamp body and the driving lever and the locating convex block 14 on the driving lever 7 and the clamp body 1.When hinge type shift fork heart carrier cooperates clamping workpiece with chuck, 7 one-tenth 90 ° of angles of clamp body 1 and driving lever, only the steel ball positioner 8 on the clamp body 1 cooperates the location with locating hole 9 on the driving lever 7.
