Abstract
The invention relates to a pair of locking pliers. The locking pliers comprise a plier body and a locating mechanism. The plier body comprises plier handles and plier jaws. The ends of the plier jaws are located on the outer edge of a cup-shaped lock ring and can make the cup-shaped lock ring deform. The locating mechanism comprises a guide plate and a locating shaft. Limiting pins are symmetrically arranged on the plier jaws. Kidney-shaped slots are symmetrically formed in the guide plate. The kidney-shaped slots limit the opening and closing degree of the plier jaws. The middle of the guide plate is fixedly connected with one end of the locating shaft. The locating shaft is perpendicular to the guide plate. The other end of the locating shaft is matched with the end face of a lock nut and provided with angular pins matched with lock grooves of the lock nut. The angular pins and the plier jaws are arranged alternately. The lock nut locking pliers do not need impact force in the using process and guarantee stressing controllability in the locking process, and potential assembly quality hazards caused by impact force are decreased.
Description
Technical field
The present invention relates to a kind of stop nut locking pliers, especially a kind of stop nut locking pliers, are suitable for cup-shaped retainer and prevent
The locking of loose nut.
Background technology
Stop nut can ensure that nut does not produce rotation after installing.A kind of structure therein is deformed by cup-shaped retainer,
Block outside stop nut to be uniformly arranged in axial locked groove and realize anti-loosening function.Four have been uniformly arranged outside general nut altogether
Locked groove, cup-shaped retainer is using punch tool by the locked groove of retainer blastic deformation to nut.The size of this impulsive force and generation
Deformation accurately cannot control, there is the assembling risk that connection loosing and retainer occur crackle etc..
Content of the invention
It is an object of the invention to provide a kind of stop nut locking pliers, it is possible to achieve no impulsive force work, it is possible to control
The deflection of cup-shaped retainer, it is ensured that the functional reliability of stop nut groove.
The concrete technical scheme of the present invention is, described stop nut locking pliers include caliper, detent mechanism, described pincers
Body includes clamp handle and jaw, and vice jaw part portion is located at the outer rim of cup-shaped retainer and deforms can cup-shaped retainer, and detent mechanism includes
Guide plate, locating shaft, are symmetrically arranged with spacer pin on jaw, be symmetrically arranged with kidney slot on guide plate, the kidney slot of guide plate with spacing
Pin matches, and makes guide plate on the jaw, described kidney slot along jaw be opened and closed when spacer pin track arrange, kidney slot limit
The opening and closing amount of jaw is made；The middle part of guide plate is fixedly connected one end of locating shaft, and locating shaft is vertically arranged with guide plate, locating shaft
The other end coordinates and is provided with the angular pin that matches with stop nut locked groove, described angular pin and pincers with stop nut end face
Mouth interlaced arrangement.
The position for being coordinated with stop nut end face on described locating shaft is additionally provided with and the prolonging of stop nut minor diameter fit
Extending portion.
Extension spring is provided with described jaw, and extension spring keeps jaw minimum state in its natural state.
Described locating shaft is coordinated on guide plate by square groove, and cooperation position is provided with straight pin.
Stop nut locking pliers of the present invention pass through to arrange stopper slot on guide plate, it is ensured that jaw opens and closes at specified
In the range of, it is to avoid enter unexpected gouge that small space caused to part and locking deformation is excessive and produce retainer and split
Stricture of vagina.Tension spring is placed between caliper rotating pin and guide plate, and operator overcomes less pulling force i.e. expansible or clutches jaw,
While also ensureing that caliper is in closure state under non-working condition all the time.By ensureing pincers using locating shaft and angular latch structure
The accuracy of mouth position.Meanwhile, when needing the stop nut to different size to lock, easily detent mechanism can be entered
Row is changed and is used, and range is wide, easy to operate.The present invention does not need impulsive force in use, and ensure that in locking process
The controllability of middle reinforcing, reduces the hidden danger of quality that impulsive force is produced to assembling.

Specific embodiment
As illustrated, stop nut locking pliers include caliper, detent mechanism, described caliper includes clamp handle 1 and jaw, pincers
Mouth end is located at the outer rim of cup-shaped retainer and deforms can cup-shaped retainer, and detent mechanism includes guide plate 6, locating shaft 8, on jaw
Spacer pin 5 is symmetrically arranged with, kidney slot on guide plate 6, is symmetrically arranged with, the kidney slot of guide plate 6 is matched with spacer pin 5, makes guide plate
6 on the jaw, described kidney slot along jaw be opened and closed when spacer pin 5 track setting, kidney slot limits opening for jaw
The amount of closing；The middle part of guide plate 6 is fixedly connected one end of locating shaft 8, and locating shaft 8 is vertically arranged with guide plate 6, the other end of locating shaft 8
Coordinate and be provided with the angular pin 9 for matching with stop nut locked groove with stop nut end face, described angular pin 9 is handed over jaw
Wrong arrangement.
The position for being coordinated with stop nut end face on described locating shaft 8 is additionally provided with and the prolonging of stop nut minor diameter fit
Extending portion.
Extension spring 4 is provided with described jaw, and extension spring 4 keeps jaw minimum state in its natural state.
Described locating shaft 8 is coordinated on guide plate 6 by square groove, and cooperation position is provided with straight pin 7.
During work, the caliper of hand-held locking pliers, jaw is opened to the outer rim of cup-shaped retainer, by the angular pin 9 on locating shaft 8
In the locked groove of insertion stop nut, while end face is leaned against on the end face of assembled shaft, clamp handle position is held, note while slow reinforcing
Anticipate the deformation state of cup-shaped retainer, put in place or till spacer pin 5 reaches the bottom of gain until the deformation of cup-shaped retainer.
