Abstract

The invention discloses a bolt set for connecting plate and shaft parts. A bushing sleeves the unthreaded cylindrical part of a bolt, wherein the unthreaded cylindrical part of the bolt is a tapered cylinder of which the diameter is enlarged towards a bolt head; an inner hole of the bushing forms a same-taper clearance fit relationship with the tapered cylinder of the bolt. According to the bolt set, the advantages of a conventional bolt and nut set as a fastening part are reserved; meanwhile, the bushing with the tapered hole of the bushing is introduced, the thin-walled part bushing is deformed along with the screwing of a nut, and after the plate and shaft parts are connected through the bolt set, the concentricity of two connected plates (shafts) is ensured, the bolt set functions as a positioning dowel, and the safe and stable torsion of the two connected plates (shafts) is achieved, so that the normal work of equipment with the plates (shafts) and a workpiece is ensured, and the production and working safety is ensured.

Description

Dish, axial workpiece connect the bolt kit adopted
technical field:
The present invention relates to TMFC field, specifically a kind of dish, axial workpiece connect the bolt kit adopted.
background technique:
Bolt and nut external member is a kind of conventional fastenings, if but dish, axial workpiece adopt common bolt and nut external member to connect, along with the rotation of dish, axial workpiece, just easily produce between bolts and nuts and get loose, thus the normal work of equipment is affected, even also cause security incident, in order to address this problem, though also take some measures in existing design and installation, but still the situation that can not bolt avoided completely to get loose occurs.
summary of the invention:
The object of the present invention is to provide a kind of dish, the interconnective bolt kit of axial workpiece for running up, existingly easily automatically producing the problem got loose for coiling, between the bolts and nuts that also exist of the interconnective bolt and nut external member of axial workpiece to solve.
Technological scheme of the present invention is: dish, axial workpiece connect the bolt kit adopted, be made up of bolt, lining and self-locking nut, lining is enclosed within the non-threaded cylindrical part of bolt, the conical cylinder that the unthreaded sections cylinder of bolt diametrically expands to bolt head direction, the conical cylinder of lining endoporus and bolt is in tapering clearance fit relationship.
The length of lining depends on: before locking nut is threaded to the thread root of bolt, and the cone-shaped inner hole of lining and the tapered cylinder of bolt start to contact.
Lining cone-shaped inner hole minimum diameter place diameter dimension should be greater than the large footpath of outside thread of bolt.
The thin-walled parts of lining to be thickness be about 1-3mm.
The present invention has following beneficial effect: the present invention had both remained the advantage of existing bolt and nut external member as fastenings, introduce again the lining of band cone shape hole simultaneously, along with tightening of nut, thin-walled parts lining can deform, dish, after axial workpiece is interconnected by this bolt kit, ensure that two connected dishes (axle) are concentric, bolt kit now serves the effect of positioning dowel, interconnective two dish (axle) safety, stable torsion pass is achieved, thus ensure that the normal work of residing equipment and workpiece, guarantee that the safety of producing and working is carried out.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention.
1-bolt in figure, 2-lining, 3-self-locking nut.
embodiment:
Below in conjunction with accompanying drawing, the invention will be further described:
As shown in Figure 1, dish, axial workpiece connect the bolt kit adopted, be made up of bolt 1, lining 2 and self-locking nut 3, lining 2 is enclosed within the non-threaded cylindrical part of bolt 1, the conical cylinder that the unthreaded sections cylinder of bolt 1 diametrically expands to bolt head direction, the conical cylinder of lining 2 endoporus and bolt 1 is in tapering clearance fit relationship.
The length of lining 2 depends on: before locking nut 3 is threaded to the thread root of bolt 1, and the cone-shaped inner hole of lining 2 and the tapered cylinder of bolt 1 start to contact.
Lining 2 cone-shaped inner hole minimum diameter place diameter dimension should be greater than the large footpath of outside thread of bolt 1.
The thin-walled parts of lining 2 to be thickness be about 1-3mm.
Be Spielpassung when lining 2 starts to load bolt 1, along with tightening of nut, the cooperation of the two is transitioned into interference fit gradually, and now, thin-wall part lining 2 also can deform, and last self-locking nut dead bolt section strikes the groove internal locking of distortion stud bolt.
