Abstract
The utility model relates to a fastening piece, in particular to a bolt fastening device with an anti-loosing self-locking structure, which is mainly applied to taking the clamping anti-loosing self-locking measures to a bolt fastening piece on casting industrial production lines or vibrating machines. Good anti-loosing effect is obtained when the bolts of vibrating machines are fastened and thereby the service life of the vibrating machines is prolonged. The technical scheme is that a threaded piece with the anti-loosing self-locking structure consists of a nut and a tapered cushion plate matched with the nut. The utility model is characterized in that female threads are arranged on the inner wall of the nut and a locking piece extending along the axial direction of the nut is arranged atthe end of the nut; and a through hole is arranged in the tapered cushion plate, the root of the tapered cushion plate is a ring plate, a tapered ring extending along the axial direction of the ringplate is arranged on the ring plate and the inner wall of the tapered ring is tapered.
Description
Technical field
The utility model relates to a kind of fastening piece, and specifically a kind of bolt clamp device with locking self-locking structure is mainly used on the foundary industry production line or on the vibrating mechanical equipment, the locking self-locking measure of the clamping of bolt fastener.The bolton of vibrating mechanical equipment is had locking preferably, reach the working life that prolongs vibrating machine.
Background technique
In machine-building, vibratory equipment is used a lot, and the fastening connection between vibrating carrier and the vibration source generally all adopts bolt fastener to realize.And on the foundry production line, the vibrating machine of application, vibratory equipment be as vibratory shake-out machine, vibratory crusher, and vibrating conveyor, oscillating feeder, vibrating screen classifier, the vibration plain bumper all is to constitute vibrating mechanical equipment by vibrating carrier and vibrating source.The large-scale vibrating equipment that develops in vibrating machine at present is widely used especially, and the corresponding work environment is more abominable, and ocsillator strenght is big, and the clamping bolt on the structural member is required to adapt to production requirement and usability better.General fastening locking measure can not be satisfied technological requirement.
Summary of the invention
The purpose of this utility model be the design a kind of bolt clamp device with locking self-locking structure, be used on the vibratory equipment after, can make the bolt between vibrating carrier and the vibrating source after being fastenedly connected, have locking auto-lock function.
The technological scheme that provides according to the utility model, described threaded piece with locking self-locking structure, comprise the nut and the taper backing plate that cooperatively interact, it is characterized in that: the inwall at nut has internal thread, and the axially extended lock sheet along nut is set in the end of nut; Described lock sheet is a root near an end of nut, and the other end of lock sheet is a head, and the outer surface of described lock sheet has tapering, makes the external diameter of the external diameter of described root greater than described head; In the described taper backing plate through hole is arranged, the root of taper backing plate is an annular slab, axially extended taper ring along described annular slab is set on described annular slab, described taper ring is the bottom near an end of annular slab, the other end of taper ring is the end, the inwall of described taper ring has tapering, makes the internal diameter of the internal diameter of described bottom less than described end; The internal diameter of described end is greater than the external diameter of described head, less than the external diameter of described root.
Axial gap along nut is set on the described lock sheet.Described lock sheet is positioned at described taper ring; And the head of described lock sheet is pressed close to the bottom of described taper ring.
The utility model has the advantages that: simple in structure, easy to operate.Utilize the self-lock mechanism of Morse's taper, under certain pretightening force effect, it is locking to reach self-locking.
