Abstract
The invention relates to a locking pliers, which comprises a pliers body and a positioning mechanism, wherein the pliers body comprises pliers handles and pliers jaws, the end parts of the pliers jaws are positioned at the outer edges of cup-shaped lock rings and can deform the cup-shaped lock rings, the positioning mechanism comprises guide plates and positioning shafts, limiting pins are symmetrically arranged on the pliers jaws, waist-shaped grooves are symmetrically arranged on the guide plates, and the waist-shaped grooves limit the opening and closing amounts of the pliers jaws; the middle part fixed connection location axle of baffle one end, location axle and baffle perpendicular setting, the other end and the locknut terminal surface cooperation of location axle are provided with the angle round pin with locknut locked groove matched with, angle round pin with keep silent staggered arrangement. The invention does not need impact force in use, ensures the controllability of the stress application in the locking process, and reduces the hidden danger of the impact force on the quality of assembly.
Description
Technical Field
The invention relates to locknut locking pliers, in particular to locknut locking pliers which are suitable for locking cup-shaped locknuts.
Background
The locknut can ensure that the nut does not rotate after being installed. One of the structures is deformed through the cup-shaped lock ring, and axial lock grooves are uniformly distributed outside the locking nut to realize the locking function. Four lock grooves are uniformly distributed outside the common nut, and the cup-shaped lock ring adopts a punch tool to impact and deform the lock ring into the lock grooves of the nut. The impact force and the generated deformation cannot be accurately controlled, and the assembly risks of loosening the structure, cracking the lock ring and the like exist.
Disclosure of Invention
The invention aims to provide a locknut locking clamp which can realize the work without impact force, can control the deformation of a cup-shaped lock ring and ensure the working reliability of a locknut groove.
The locknut locking pliers comprise pliers bodies and a positioning mechanism, wherein the pliers bodies comprise pliers handles and pliers jaws, the end parts of the pliers jaws are positioned at the outer edges of cup-shaped lock rings and can deform the cup-shaped lock rings, the positioning mechanism comprises guide plates and positioning shafts, limiting pins are symmetrically arranged on the pliers jaws, kidney-shaped grooves are symmetrically arranged on the guide plates, the kidney-shaped grooves of the guide plates are matched with the limiting pins, the guide plates are arranged on the pliers jaws, the kidney-shaped grooves are arranged along the track of the limiting pins when the pliers jaws are opened and closed, and the kidney-shaped grooves limit the opening and closing amount of the pliers jaws; the middle part fixed connection location axle of baffle one end, location axle and baffle perpendicular setting, the other end and the locknut terminal surface cooperation of location axle are provided with the angle round pin with locknut locked groove matched with, angle round pin with keep silent staggered arrangement.
The positioning shaft is also provided with an extension part matched with the inner diameter of the locknut at the position matched with the end face of the locknut.
The jaw is provided with an extension spring which keeps the minimum state of the jaw in a natural state.
The positioning shaft is installed on the guide plate in a matched mode through the square groove, and cylindrical pins are arranged at the matched positions.
According to the locknut locking pliers, the limiting groove is formed in the guide plate, so that the jaws are opened and closed within a specified range, and the situation that unexpected knocks and excessive locking deformation are caused to parts when the locknut locking pliers enter a narrow space to cause cracks on the locking ring is avoided. The tension spring is arranged between the rotating pin shaft of the clamp body and the guide plate, so that an operator can open or pinch the clamp jaw by overcoming small tension, and the clamp body is always in a closed state in an unoperated state. The accuracy of the jaw position is ensured by adopting a positioning shaft and an angular pin structure. Meanwhile, when locknuts of different specifications are required to be locked, the positioning mechanism can be conveniently replaced, and the locknut locking device is wide in application range and convenient to operate. The invention does not need impact force in use, ensures the controllability of the stress application in the locking process, and reduces the hidden danger of the impact force on the quality of assembly.

Detailed Description
As shown in the figure, the locknut locking pliers comprise pliers bodies and positioning mechanisms, wherein the pliers bodies comprise pliers handles 1 and pliers jaws, the end parts of the pliers jaws are positioned at the outer edges of cup-shaped lock rings and can deform the cup-shaped lock rings, the positioning mechanisms comprise guide plates 6 and positioning shafts 8, limiting pins 5 are symmetrically arranged on the pliers jaws, kidney-shaped grooves are symmetrically arranged on the guide plates 6, the kidney-shaped grooves of the guide plates 6 are matched with the limiting pins 5, the guide plates 6 are arranged on the pliers jaws, the kidney-shaped grooves are arranged along the track of the limiting pins 5 when the pliers jaws are opened and closed, and the kidney-shaped grooves limit the opening and closing amount of the pliers jaws; the middle part fixed connection location axle 8 of baffle 6 one end, location axle 8 and baffle 6 perpendicular setting, the other end and the locknut terminal surface cooperation of location axle 8 are provided with the angle round pin 9 with locknut locked groove matched with, angle round pin 9 with keep silent staggered arrangement.
The positioning shaft 8 is also provided with an extension part matched with the inner diameter of the locknut at the position matched with the end face of the locknut.
The jaw is provided with an extension spring 4, and the extension spring 4 keeps the minimum state of the jaw in a natural state.
The positioning shaft 8 is arranged on the guide plate 6 in a matched mode through a square groove, and a cylindrical pin 7 is arranged at a matched position.
When the locking pliers are in operation, the pliers body of the locking pliers are held, the pliers mouth is opened to the outer edge of the cup-shaped lock ring, the angular pin 9 on the positioning shaft 8 is inserted into the lock groove of the locknut, the end face is leaned against the end face of the assembly shaft, the pliers handle part is held by the hand, and the deformation state of the cup-shaped lock ring is slowly stressed until the cup-shaped lock ring is deformed in place or the limiting pin 5 reaches the bottom of the waist groove.
