Abstract

The utility model discloses a pair of calipers for assembling and disassembling specific external circlip. A spring is arranged in a left caliper (1) and a right caliper (2), and a cylindrical pin and a circlip are used for connecting the left caliper (1), the right caliper (2) and the springs. A working slot is arranged on the working positions of the left caliper (1) and the right caliper (2), and holes are respectively formed on the left caliper (1) and the right caliper (2) and connected with the corresponding connection paw on the spring. According to the utility model, the opening portion of the circlip is inserted into a specific slot of the calipers, and the circlip can be assembled or disassembled by spreading the opening portion by the calipers. Such structure reduces the assembly/disassembly complexity of the circlip, reduces the labor intensity and improves the working efficiency, and the assembly/disassembly of the circlip can be executed at high efficiency by one person.

Description

The clamp of the extraordinary outer back-up ring of mounting or dismounting

Technical field:

The utility model relates to a kind of back-up ring mounting or dismounting tools.

Background technology:

In high-power gearbox, many parts such as gear, axle, adapter sleeve all are that outer back-up ring fixes its axial location.This back-up ring hardness height, good rigidly.Because the space of gearbox is little, the power that this back-up ring for hole or tower adorning, disassemble and use, is not adorned, needed when tearing open is big.Owing to dress, tear very difficulty open, often need two people to cooperate and just can finish with multiple instrument.When having only a maintenance personal to keep in repair in the open air, if instrument is incomplete, the difficulty of adorning, tearing open is bigger.At present, the clamp that assembling and maintenance personal use, it is loosely organized, needs both hands to hold clamp during operation, inconvenient operation, and the poor rigidity of clamp, clamp working position hardness is low, fragile.

Summary of the invention:

The technical problems to be solved in the utility model is: a kind of clamp of installing and removing extraordinary outer back-up ring are provided, and the need both hands be held clamp, inconvenient operation, flimsy deficiency when overcoming the operation that exists in the prior art.

The utility model is to constitute like this: it comprises a left side half pincers (1) and right half pincers (2), in a left side half pincers (1) and right half pincers (2) spring (3) is arranged, and straight pin (4) is connected a left side half pincers (1), right half pincers (2), spring (3) with collar (5).

There is work nest (6) working position of half pincers (1) and right half pincers (2) on a left side.

Half clamps (1) upward porose (7) on a left side, and half pincers (2) are gone up porose (8) on the right side, and connection pawl (9), (10) are arranged on spring (3), hole (7), (8) and connection pawl (9), (10) corresponding connection.

Design feature of the present utility model is as follows:

A, according to the characteristics of a back-up ring design left side half pincers and right half pincers, and on a left side the different work nest of working position katal of half pincers and right half pincers, make it to adapt, and the hardness of this part proposed high requirement with the breach of back-up ring, and the volume of working position is little, and occupation space is little.

Slot milling shock mount in b, a left side half pincers and right half pincers abuts against together two working positions of two halves pincers by spring, is convenient to one hand and operates.

C, straight pin and collar are fitted together a left side half pincers, right half pincers, spring, and the moment that straight pin bears is big, and collar is dismantled easily, is easy to carry.

Operation principle of the present utility model is that the opening portion with back-up ring snaps in the special groove of clamp, with clamp it is strutted and adorns, tears open.This structure reduced this kind back-up ring dress, tear difficulty open, a people can convenient and efficient installation and removal, reduce labour intensity, increase work efficiency.

Fig. 1 is the clamp schematic diagram;

Fig. 2 is an A-A cutaway view among Fig. 1;

Fig. 3 is to be that B among Fig. 1 is to view;

Fig. 4, Fig. 5 are the schematic diagram of a left side half pincers (1), are respectively right view, front view;

Fig. 8, Fig. 9 are the enlarged diagram of spring (3), are respectively front view, vertical view.

The specific embodiment:

Embodiment of the present utility model: according to the characteristics of a back-up ring design left side partly clamp 1 and the right side partly clamp 2, and partly clamp 1 and right 2 the different work nest 6 (seeing that B is to view) of working position (top) katal of partly clamping on a left side, make it to adapt with the breach of back-up ring, and this part carried out specially treated, make hardness reach requirement.Partly clamp on a left side 1 and the right side partly clamp and hole 7,8 in 2 respectively, shock mount 3 is installed, make the connection pawl 9,10 and hole 7,8 corresponding connections of spring 3, two working positions that two halves clamped by spring 3 abut against together, are convenient to one hand and operate.Straight pin 4 and collar 5 with a left side partly clamp 1, the right side partly clamps 2, spring 3 is fitted together, the moment that straight pin 4 bears is big, collar is dismantled easily, is easy to carry.
