Abstract
The utility model relates to a special tool for mounting or demounting retainers rings for shafts and bores, in particular to pliers of retainer rings for shafts and bores. The traditional pliers of retainer rings for shafts and bores are not used in common; with increasing of the diameter of the retainer rings, handles of the pliers of retainer rings for shafts and bores lengthen; in order to mount or demount the retainer rings for shafts and bores, a series of retainer ring pliers are required; in addition, jaws and a body in the traditional retainer ring pliers are forged integrally, and after the jaws are damaged, scrapping of the body causes great waste. The pliers of retainer rings for shafts and bores is characterized in that A left-handed and right-handed screw is rotated with a reversing ratchet wrench to allow a left-handed nut and a right-handed nut to leave or approach the center of the screw at the same time, and the jaws are opened or closed; the outer jaws and a plier body are split, different jaws can be mounted on one plier body to mount or demount all retainer rings for shafts and bores, economy is benefited, time and labor efficiency is high, and the pliers of retainer rings for shafts and bores are safe and reliable.
Description
Technical field
The utility model relates to a kind of axis hole and shares retainer pliers, specifically a kind of tool tong that not only can mount and dismount shaft block ring but also can mount and dismount hole back-up ring.
Background technology
Tradition retainer pliers is divided into external circlip plier and internal circlip plier, and along with the increase of back-up ring diameter, the handle portion of axle use and internal circlip plier is also along with lengthening, in order to mount and dismount axle, a series of retainer pliers of hole back-up ring needs, the expense of buying is higher, and carries inconvenience; Chela and the caliper of tradition retainer pliers are integrated forging, and after chela damages, caliper is scrapped together and caused very large waste; When back-up ring is larger in addition, have very large bounce, in the time that the hand-power of installation personnel can not maintain, back-up ring can eject, and has certain potential safety hazard.
Summary of the invention
The purpose of this utility model is to provide a kind of tool tong that not only can mount and dismount shaft block ring but also can mount and dismount hole back-up ring; And by caliper and chela split design, avoid causing caliper to damage together after chela damage; A caliper is installed different chelas, can complete the installation and removal of all axles, hole back-up ring.
The technical solution adopted in the utility model is: axis hole shares retainer pliers and is made up of caliper and chela two parts, avoids causing caliper to damage together after chela damage; Caliper front end has eight chela installing holes, has three installing holes on each chela, can make chela form altogether six groups of different setting angles, to adapt to dismounting and the installation of different-diameter back-up ring; Open and shrink left-right rotary nut, left-right rotary screw rod, the ratchet spanner capable of reversing installed by caliper afterbody of caliper are realized, open large with convergent force and open with convergent force and can keep, by exchanging chela, can realize the installation and removal of various shaft block rings and various hole back-up ring.
The beneficial effects of the utility model are: realized the installation and removal that caliper can be realized to various shaft block rings and hole back-up ring by adjusting or change different chelas, both avoided one-tenth produced in series caliper, also after having avoided chela to damage, cause caliper to damage together, can cost saving.Caliper opens large with convergent force and opens with convergent force and can keep in addition, makes the laborsaving and safety of the installation of back-up ring, also makes the installation of back-up ring no longer be subject to the impact of installation personnel hand-power size.
Brief description of the drawings
Below in conjunction with accompanying drawing and case study on implementation, the utility model is further illustrated.
Fig. 1 is the schematic diagram that the present invention is used as external circlip plier;
Fig. 2 is the schematic diagram that the present invention is used as internal circlip plier;
Fig. 3 is the scheme of installation of left and right spin nut and clamp handle;
Fig. 4 is the scheme of installation of chela and caliper;
Fig. 5 is the schematic diagram of chela part;
Detailed description of the invention:
In figure: 1, clamp handle one, 2, clamp handle two, 3, right-handed nut's installing plate, 4, hexagonal sunk screw, 5, right-handed nut, 6, reversing ratchet wrench, 7, left-handed nut, 8, left-handed nut installing plate, 9, left-right rotary screw rod, 10, chela mounting screw, 11, chela.
The utility model axis hole shares retainer pliers and is made up of caliper and chela two parts.Chela is installed together (as Fig. 4) by chela mounting screw 10 and caliper, and chela needs in pairs and symmetrical installation, in the time that the back-to-back symmetry of a pair of chela is installed to caliper, for the installation and removal (as Fig. 1) of shaft block ring; In the time that the face-to-face symmetry of a pair of chela is installed to caliper, the installation and removal (as Fig. 2) for hole with back-up ring; Two clamp handle front ends have eight chela installing holes, have three installing holes (as Fig. 5) on each chela, and clamp handle installing hole coordinates with chela installing hole, can make chela form altogether six groups of different setting angles, to adapt to dismounting and the installation of different-diameter back-up ring; Clamp handle one is connected with clamp handle two intersection hinge shapes, and two clamp handles can be done relative rotary motion around hinge pin; Reversing ratchet wrench 6 coordinates with outer six sides in the middle of left-right rotary screw rod 9, determines direction of rotation by the commutation driving lever of adjusting on ratchet spanner; Left-right rotary screw rod 9 two ends are connected with right-handed nut 5 and left-handed nut 7 respectively by screw thread, right-handed nut 5 is installed to (as Fig. 3) in clamp handle 1 by right-handed nut's installing plate 3 and hexagonal sunk screw 4, left-handed nut 7 is installed in clamp handle 22 by left-handed nut installing plate 8 and hexagonal sunk screw 4, rotating ratchet wrench rotates left-right rotary screw rod 9 in the same direction, right-handed nut 5 and left-handed nut 7 simultaneously away from or near the mid point of left-right rotary screw rod 9, thereby chela opened or shrink, realizing the function of installation and removal axle use or hole back-up ring.A caliper can be realized the installation and removal of various shaft block rings and hole back-up ring by adjusting or change different chelas, both avoided series to buy traditional retainer pliers, also after having avoided traditional retainer pliers due to chela damage, cause caliper to damage together, can save a large amount of expenses.Caliper opens large with convergent force and opens with convergent force and can keep in addition, makes the installation of back-up ring not be subject to the impact of installation personnel hand-power size, makes the installation of back-up ring become laborsaving and safety.
