The groove is knocked through external force of an operator for locking, the working strength is high, the working efficiency is low, and the nut is extremely easy to damage. The transition head is connected among the plurality of sections of chains, the two ends of the transition head are respectively hinged with the chains at the two sides, the transition head is provided with a hook head on the working surface, and the width dimension of the hook head is consistent with the width of the groove nut; a spanner bar is also provided at the end of the outside chain. The assembling structure is simple, the universality is high, the working efficiency can be improved, the labor intensity of workers is reduced, and the assembling quality is ensured.

Description

Disassembling tool for groove nut

Technical Field

The utility model relates to a mechanical equipment maintenance assembly field, concretely relates to assembly and disassembly tools of groove nut.

Background

During the maintenance assembly of mechanical equipment, a grooved form of nut is often encountered, as shown in fig. 1. The nut has the main function of axially positioning and locking the shaft and the tool rest. Currently, the following methods are mainly adopted for assembling the structure: the groove is knocked by the external force of an operator to lock the groove, but the mode has the following defects: the maintenance personnel have high working strength and low working efficiency; because of striking to cause the atress uneven, very easily damage the nut, locking torque can't guarantee. The existing tool has a single form and no universality.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a main aim at: overcome prior art not enough, provide the assembly and disassembly tools of a take slot form nut.

The utility model provides a groove nut dismounting tool, which adopts transition head connection among a plurality of sections of chains, wherein the transition head is respectively hinged with the chains at two sides at two ends, the transition head is provided with a hook head on the working surface, and the width dimension of the hook head is consistent with the groove width of the groove nut; a spanner bar is also provided at the end of the outside chain.

Advantageously or optionally, the transition head is hinged at both ends with the chains at both sides through long pin shafts and is fixed through a retaining ring for the shaft.

Advantageously or alternatively, the long pin shaft comprises a central shaft and threaded portions at both ends, the shaft being articulated to the chain.

Advantageously or alternatively, the threaded part of the long pin shaft penetrates out of the transition heads from the upper end and the lower end and is fixed through the nut.

Advantageously or optionally, the working surface of the transition head is provided with a T-shaped groove, and the hook head is installed in the T-shaped groove through a fixture block.

Advantageously or alternatively, the hook head is removably mounted in a T-shaped slot.

Advantageously or alternatively, a bushing is welded at the end of the outer chain, in which bushing said spanner bar is inserted.

Advantageously or alternatively, the position and number of said transition heads are adjustable.

Has the advantages that: the assembling structure is simple, the universality is high, the working efficiency can be improved, the labor intensity of workers is reduced, and the assembling quality is ensured.

The features, functions, and advantages that have been discussed can be achieved independently in various examples or may be combined in yet other examples. Further details of the examples can be seen with reference to the following description and the attached drawings.

Drawings

The illustrative examples, as well as a preferred mode of use, further objectives, and descriptions thereof, will best be understood by reference to the following detailed description of an example of the present invention when read in conjunction with the accompanying drawings, wherein:

FIG. 1 is a schematic view of a grooved nut;

FIG. 2 is a schematic view of the disassembling tool of the present invention;

FIG. 3 is a schematic view of a long pin shaft;

fig. 4 is a disassembly schematic view.

Detailed Description

The disclosed examples will be described more fully with reference to the accompanying drawings, in which some (but not all) of the disclosed examples are shown. Indeed, many different examples may be described and should not be construed as limited to the examples set forth herein. Rather, these examples are described so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

Referring now to the embodiment shown in fig. 2, the groove nut dismounting tool comprises a wrench rod 1, a sleeve 2, a chain 7, a long pin shaft 3, a nut 4, a transition head 6 and a hook head 5. Every two sections of the chain 7 are fixed by replacing at least one section of the long pin shaft 3, the long pin shaft 3 is assembled with a single section of chain plate, two ends of the chain are fixed by using a retainer ring for a shaft, transition heads 6 are arranged on the long pin shaft 3, a plurality of transition heads 6 are arranged on the chain 7 in random and uneven distribution, and the outer end of the chain is screwed and fixed by using nuts 4.

When the nut is disassembled, the hook head 5 is installed on the through type sliding groove of the transition head 6, the size of the hook head 6 can be freely selected according to the size of the root grooved nut groove, the position of the transition head 6 on the chain 7 is selected according to the outer diameter of the grooved nut to be installed, and the sleeve 2 and the tail end of the chain 7 are welded and fixed and cannot be movably glued. When the wrench is used, the hook head 5 hooks the groove of the nut with the groove, the wrench rod 1 penetrates into the sleeve 2, and the nut with the groove is screwed/unscrewed after the nut with the groove is compressed, so that the purpose of disassembly is achieved.

The description of the different advantageous arrangements has been presented for purposes of illustration and description, but is not intended to be exhaustive or limited to the examples in the form disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art. Additionally, the different advantageous examples may describe different advantages as compared to other advantageous examples. The example or examples selected are chosen and described in order to best explain the principles of the examples, the practical application, and to enable others of ordinary skill in the art to understand the disclosure for various examples with various modifications as are suited to the particular use contemplated.
