Abstract
The invention belongs to zircon sand technical field of processing equipment, and in particular to the fastener of zircon sand process equipment, including eyelet bolt and thick hexagonnut；The screw thread of the eyelet bolt be trapezoidal thread M20, screw pitch t=5,10.9 grades of mechanical performance；Thick hexagonnut, screw thread be trapezoidal thread M20, screw pitch t=5, mechanical performance is to 8 grades；Thick hexagonnut opens the hole of diameter 1.2mm.The fastener of zircon sand process equipment provided by the invention, zircon sand rest on the time in screw thread with regard to short, along with clearance hole is provided with, completely eliminate stuck phenomenon when nut is tightened or unscrewed.
Description
Technical field
The invention belongs to zircon sand technical field of processing equipment, and in particular to the fastener of zircon sand process equipment.
Background technique
Zircon sand process equipment, which shows eyelet bolt and thick hexagonnut use, zircon sand (D50100) occasion passed in and out,
When tightening and unscrewing nut, tiny and hard zircon sand is stuck in screw thread, prevents and stuck nut moves, cause the two screw thread
Sliding teeth, fracture of wire, routine use first and second just need gas cutting to scrap bolt.
Summary of the invention
In view of the above technical problems, the present invention provides a kind of fastener of zircon sand process equipment, solves tiny and hard
Zircon sand the problem of both being stuck in nut in screw thread and can tighten or unscrew in the same old way, and will not damage screw thread.
The fastener of zircon sand process equipment, including eyelet bolt and thick hexagonnut；The screw thread of the eyelet bolt
For trapezoidal thread M20, screw pitch t=5,10.9 grades of mechanical performance；
Thick hexagonnut, screw thread be trapezoidal thread M20, screw pitch t=5, mechanical performance is to 8 grades；Thick hexagonnut opens diameter
The hole of 1.2mm.
The fastener of zircon sand process equipment provided by the invention, nut on bolt when turning, because of the two junction
Thread number reduces (screw pitch increases to 5 by 2.5), and zircon sand rests on the time in screw thread with regard to short, thorough along with being provided with clearance hole
Bottom eliminates stuck phenomenon when nut is tightened or unscrewed.Firmly light when now working, daily Reusability 4 times can be used continuously
Time a year and a half, which just wears up to, scraps.By every equipment using 4 sets totally 40 equipment calculating, greatly reduce the buying of part at
Sheet and workload.
Specific embodiment
It is described in conjunction with the embodiments the specific technical solution of the present invention.
After the invention, component is made of eyelet bolt and two part of thick hexagonnut, is used as fastener.
By the eyelet bolt of original regular screw threads M20 coarse thread t=2.5, it is converted into the movable joint spiral shell of trapezoidal thread M20 screw pitch t=5
Bolt, while mechanical performance is improved by 5.9 to 10.9 grades；
By the thick hexagonnut of original regular screw threads M20 coarse thread t=2.5, it is converted into the hexagonal thickness spiral shell of trapezoidal thread M20 screw pitch t=5
Mother, mechanical performance are improved by 5 to 8 grades, while pressing screw pitch direction, bottom diameter t1Place opens the hole of diameter 1.2mm, convenient for freely falling
Fall tiny zircon sand.
The present invention is mainly on the one hand to change thread type and mechanical performance, is on the other hand opened in the thread root of nut
The phenomenon that hole has prevented zircon sand and has been stuck in screw thread, and nut can not turn.
