Abstract
The utility model discloses a tool for processing an internal hexagonal hole of an anti-shearing high-locked bolt. The tool comprises a die molding sleeve, a guide sleeve, a workpiece seat and a hexagonal male die component, wherein a through hole is formed in the die molding sleeve; the guide sleeve and the workpiece seat are sleeved in the through hole in the die molding sleeve, are in clearance fit with the through hole, and are positioned at two ends of the die molding sleeve respectively; the hexagonal male die component consists of a screw rod and a hexagonal male punching head positioned at one end of the screw rod; the screw rod is arranged in a screw hole of the guide sleeve through a screw thread; the hexagonal male punching head is positioned inside the die molding sleeve; a positioning hole is formed in the workpiece seat; and a spring is arranged between opposite inner ends of the guide sleeve and the workpiece seat. The internal hexagonal hole of the anti-shearing high-locked bolt is processed by adopting a punching mode, so that the processing efficiency is improved, and the coaxiality between the internal hexagonal hole of the anti-shearing high-locked bolt and the external circle of the screw rod is guaranteed; the processing belongs to cold extrusion molding, so that the surface quality of the internal hexagonal hole is high; and due to a strain hardening effect of punching, the hardness of the surface of the internal hexagonal hole is improved.
Description
Technical field
The utility model belongs to high locked bolts machining tool technical field, relates to a kind of instrument that is used to process hexagonal hole in the shearing resistance type high locked bolts.
Background technology
High locked bolts is a kind of standard component that aviation field is fastenedly connected that is widely used in, because its high reliability of connecting requirement is higher to the quality requirements of high locked bolts.The operating position of shearing resistance type high locked bolts is the hexagonal hole that is positioned at the bolt bottom, and the crudy of interior hexagonal hole influences the performance and the quality of connection of shearing resistance type high locked bolts itself.Defectives such as that if the processing of interior hexagonal hole occurs is eccentric, stress is concentrated, will cause the inefficacy of shearing resistance type high locked bolts part itself or connect unreliable.
Summary of the invention
The purpose of the utility model provides a kind of instrument that is used to process hexagonal hole in the shearing resistance type high locked bolts, utilize this instrument can guarantee to process in the axiality of hexagonal hole and screw rod cylindrical, and the surface quality of the interior hexagonal hole that processes height, hardness are big.
The technical scheme that the utility model adopted is, is used to process the instrument of hexagonal hole in the shearing resistance type high locked bolts, comprises pressing mold die sleeve, guide pin bushing, workseat and six side's formpiston assemblies; Be provided with through hole in the pressing mold die sleeve, guide pin bushing and workseat are enclosed within the through hole of pressing mold die sleeve and with via clearance and cooperate, and guide pin bushing and workseat lay respectively at the two ends of pressing mold die sleeve; Six side's formpiston assemblies are made up of threaded rod and the six side's rushing heads that are positioned at threaded rod one end end, and threaded rod is arranged on through screw thread in the screwed hole of guide pin bushing, and six side's rushing heads are positioned at the inside of pressing mold die sleeve; Be provided with locating hole in the workseat; Be provided with spring between relative two medial extremitys of guide pin bushing and workseat; The axis of the locating hole of threaded rod, six side's rushing heads and workseat is located on the same line.
The beneficial effect of the utility model is that the mode of employing punching press is carried out the processing of hexagonal hole in the shearing resistance type high locked bolts, has improved working (machining) efficiency; Guaranteed the axiality of interior hexagonal hole of shearing resistance type high locked bolts and screw rod cylindrical; Process belongs to cold-extrusion shaping, and interior hexagonal hole surface quality is high; The hardness on hexagonal hole surface in the flow harden effect of punching press improves.

Among the figure, 1. high locked bolts, 2. pressing mold die sleeve, 3. guide pin bushing, 4. locking nut, 5. six side's formpiston assemblies, 6. spring, 7. workseat, 8. centring ring, 9. threaded rod, 10. six side's rushing heads, hexagonal holes in 11..
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is elaborated.
As shown in Figure 1, the utility model provides a kind of instrument that is used to process hexagonal hole in the shearing resistance type high locked bolts, comprises pressing mold die sleeve 2, guide pin bushing 3, workseat 7 and six side's formpiston assemblies 5; Be provided with through hole in the pressing mold die sleeve 2, guide pin bushing 3 and workseat 7 are enclosed within the through hole of pressing mold die sleeve 2 and with via clearance and cooperate, and guide pin bushing 3 and workseat 7 lay respectively at the two ends of pressing mold die sleeve 2; Six side's formpiston assemblies 5 are made up of threaded rod 9 and the six side's rushings that are positioned at threaded rod 9 one end ends 10, and threaded rod 9 is arranged on through screw thread in the screwed hole of guide pin bushing 3, and six side's rushings 10 are positioned at the inside of pressing mold die sleeve 2; Be provided with locating hole in the workseat 7; Be provided with spring 6 between relative two medial extremitys of guide pin bushing 3 and workseat 7; Threaded rod 9, six side's rushings 10 is located on the same line with the axis of the locating hole of workseat 7.
Add man-hour; External diameter at pressing mold die sleeve 2 puts centring ring 8 earlier; Through centring ring 8 the utility model machining tool is installed on the punch press, workpiece shearing resistance type high locked bolts 1 is packed in the locating hole of workseat 7, with the screw rod end of needs processing facing to six side's rushings 10; And the degree of depth of hexagonal hole 11 in shearing resistance type high locked bolts 1 screw rod end will process as required, the upper-lower position of adjustment threaded rod 9 in guide pin bushing 3 screwed holes, after adjusting, cover upper locking nut 4 lockings on threaded rod 9; Six side's formpiston assemblies 5 move downward under the effect of punch press linear reciprocating motion impulse stroke with guide pin bushing 3; Spring 6 pressurizeds; The end of six side's rushings of six side's formpiston assemblies 5,10 punching press shearing resistance type high locked bolts, 1 screw rod, hexagonal hole 11 in the end of screw rod forms, during punch press linear reciprocating motion rollback stroke; Six side's formpiston assemblies 5 reset under the effect of spring 6 with guide pin bushing 3, and interior hexagonal hole 11 press works are accomplished.
Through axiality that guarantees pressing mold die sleeve 2 through holes, guide pin bushing 3 screwed holes and shearing resistance type high locked bolts 1 screw rod cylindrical and the axiality of passing through to guarantee workseat 7 locating holes and shearing resistance type high locked bolts 1 screw rod cylindrical; Make six side's rushings 10 the axis with process in the axis of hexagonal hole 11 be located on the same line, and the axis of hexagonal hole 11 and the axis of shearing resistance type high locked bolts 1 screw rod cylindrical are located on the same line in processing.The matched in clearance of guide pin bushing 3 and pressing mold die sleeve 2 can make guide pin bushing 3 under the drive of six side's formpiston assemblies 5, do linear slide, guarantees the linearity of hexagonal hole 11 in the punching press; Spring 6 can make guide pin bushing 3 drives six side's formpiston assemblies 5 reset after the punching press release.
