Abstract
The invention relates to a fixture special for a mortise of a broaching disc type part, belonging to the technical field of fixture machinery. The fixture comprises a base, an angular positioning pin, a press cover, a compression nut, a compression screw, a gasket, a screw-thread bush, a lock screw, a positioning mandrel and radial gap elimination mechanisms, wherein each radial gap elimination mechanism comprises a positioning end surface ring, a positioning stop opening ring, a radial positioning gap regulation top block, a tightening screw and a spring. By uniformly distributing the radial gap elimination mechanisms on the circumferences of two layers of positioning rings, the fixture can eliminate the positioning radial gap of the part also enable the part to be coaxial with a positioning stop opening of a puller and enhance the production efficiency and the product qualification rate of the part and the qualification rate from original 10 percent to 95 percent and directly enhance the economic efficiency by 50 percent.
Description
Technical field
The invention belongs to the anchor clamps field of mechanical technique, particularly a kind of fixture special for mortise of broaching disc type part.
Background technology
The anchor clamps location is an one positioning disk structure at present, and as shown in Figure 3, part and anchor clamps positioning disk 15 are by the location, gap, because the part location is radially gapped and broaching vibration effect, makes broaching part tongue-and-groove surface quality not reach specification requirement.
Summary of the invention
Deficiency at prior art exists the invention provides a kind of fixture special for mortise of broaching disc type part, by equally distributed elimination radial clearance mechanism on the circumference of two-layer locating ring, to reach the purpose that improves broaching part tongue-and-groove suface processing quality.
Technical scheme of the present invention is achieved in that these anchor clamps comprise chassis, angle alignment pin, gland, clamp nut, housing screw, packing ring, screw-thread bush, lock-screw, apotting spindle and elimination radial clearance mechanism; Eliminating radial clearance mechanism comprises location end face ring, positioning spigot ring, regulates radial location gap jacking block, screws screw and spring.
The connection of these anchor clamps is: end face ring bottom surface, location connects the chassis, end face connects the positioning spigot ring, the side connects regulates radial location gap jacking block, regulate radial location gap jacking block and connect the positioning spigot ring, and evenly install along positioning spigot ring circumference, screwing screw is assemblied in location end face ring and the adjusting radial location gap jacking block, screw screw spring is installed, the angle alignment pin is fixed on the positioning spigot ring, apotting spindle is positioned at the axle center of location end face ring, gland is connected with apotting spindle, compresses by clamp nut, and housing screw is evenly distributed on the gland excircle, housing screw and gland are connected with packing ring, the inboard housing screw that connects of screw-thread bush, the outside connects the positioning spigot ring, and lock-screw is positioned at screw-thread bush one side.
Described packing ring is the annulus that has gap.
The course of work of these anchor clamps: parts fixation is on anchor clamps, behind location end face ring and positioning spigot loop mapping, because part and positioning spigot ring are matched in clearance, because it is unfavorable to broaching to be positioned with the gap, adjust part moves radially for this reason, utilize to regulate radial location gap jacking block and screw screw and eliminate location, the no gap of radial clearance mechanism realization, mechanism makes adjusting radial location gap jacking block hold out against part by screwing screw, through symmetry point is found accurately back locking part, product processing back dismounting part is to unclamp screwing screw, makes adjusting radial location gap jacking block return original position by spring force part is unloaded.
Advantage of the present invention is by equally distributed elimination radial clearance mechanism on the circumference of two-layer locating ring, can eliminate part location radial clearance, make part simultaneously and draw the tool positioning spigot coaxial, improve part production efficiency and product percent of pass, qualification rate brings up to 95% by original 10%, and directly improving business efficiency is 50%.

The specific embodiment
A kind of fixture special for mortise of broaching disc type part detailed structure of the present invention is illustrated with the specific embodiment in conjunction with the accompanying drawings.
These anchor clamps as illustrated in fig. 1 and 2, these anchor clamps comprise chassis 1, angle alignment pin 4, gland 5, clamp nut 6, housing screw 7, packing ring 8, screw-thread bush 9, lock-screw 10, apotting spindle 11 and eliminate radial clearance mechanism; Eliminate radial clearance mechanism as shown in Figure 4, comprise location end face ring 2, positioning spigot ring 3, regulate radial location gap jacking block 13, screw screw 12 and spring 14.
The connection of these anchor clamps is: end face ring 2 bottom surfaces, location connect chassis 1, end face connects positioning spigot ring 3, the side connects regulates radial location gap jacking block 13, regulate radial location gap jacking block 13 and connect positioning spigot ring 3, and evenly install along positioning spigot ring 3 circumference, screwing screw 12 is assemblied in location end face ring 2 and the adjusting radial location gap jacking block 13, screw screw 12 spring 14 is installed, angle alignment pin 4 is fixed on the positioning spigot ring 3, apotting spindle 11 is positioned at the axle center of location end face ring 2, gland 5 is connected with apotting spindle 11, compresses by clamp nut 6, and housing screw 7 is evenly distributed on gland 5 excircles, housing screw 7 is connected with packing ring 8 with gland 5, the screw-thread bush 9 inboard housing screws 7 that connect, the outside connects positioning spigot ring 3, and lock-screw 10 is positioned at screw-thread bush 9 one sides.
Described packing ring 8 is for having the annulus of gap.
The course of work of these anchor clamps: parts fixation is on anchor clamps, behind location end face ring 2 and positioning spigot 3 loop mappings, because part and positioning spigot ring 3 are matched in clearance, because it is unfavorable when being positioned with the gap to broaching, adjust part moves radially for this reason, utilize to regulate radial location gap jacking block 13 and screw screw 12 and eliminate location, the no gap of radial clearance mechanism realization, mechanism makes adjusting radial location gap jacking block 13 hold out against part by screwing screw 12, through symmetry point is found accurately back locking part, product processing back dismounting part is to unclamp screwing screw 12, makes adjusting radial location gap jacking block 13 return original position by spring force part is unloaded.
