Description

A wrench for removing end cover with adjustable hole distance

technical field

The utility model belongs to the field of mechanical product manufacturing, in particular to a tool for equipment disassembly and maintenance.

Background technique

In the production of industrial enterprises, when maintaining equipment and tooling, it is often necessary to disassemble the outer sealing end cover from the fixing seat before disassembling the bearing. The sealing end cap is generally installed in the fixed seat by screwing in the thread, and the disassembly method currently adopted is mostly to be screwed out by using a special tool. For sealing end caps of different sizes and specifications, it is necessary to be equipped with various types of special tools. This has not only increased the cost of the maintenance tool, but also increased the difficulty of using and keeping the tool.

Contents of the invention

The utility model provides a dismantling end cover wrench with adjustable hole distance to solve the problems of high maintenance cost and difficult use and storage of the existing special dismantling tools.

The technical solution of the utility model is: the fixed pin is installed at the front end of the chute, the butterfly nut is threadedly connected with the upper end of the fixed pin, the fixed pin is fixedly connected with the chute through the butterfly nut, and the fastening bolt is connected with the through hole on the chute. Through connection, the fastening bolt is threaded with the butterfly nut, and the two movable blocks span the outside of the chute from the upper and lower directions of the chute, and the movable pin passes through the movable block and at the same time passes through the inner groove of the chute, butterfly type The nut is located outside the chute, the upper end of the movable pin is threaded with the butterfly nut, and the handle is fixedly connected with the chute through threads.

The utility model has the advantages of novel structure, simple manufacture, convenient use and adjustment of hole distance, the same wrench can be used for disassembly and maintenance of sealing end caps of different sizes and specifications, which makes the tools easy to store and brings great convenience to production , while reducing costs.

Among the figure, fixed pin 1, fastening bolt 2, butterfly nut 3, movable block 4, movable pin 5, chute 6, handle 7.

detailed description

The fixed pin 1 is installed on the front end of the chute 6, the wing nut 3 is threadedly connected with the upper end of the fixed pin 1, the fixed pin 1 is fixedly connected with the chute 6 through the wing nut 3, and the fastening bolt 2 is connected with the overpass on the chute 6. The holes are pierced, the fastening bolts 2 are threaded with the wing nuts 3, the two movable blocks 4 span the outside of the chute 6 from the upper and lower directions of the chute 6, the movable pin 5 passes through the movable block 4, and passes through the In the inner groove of the chute 6, the wing nut 3 is located outside the chute 6, the wing nut 3 is threaded with the upper end of the movable pin 5, and the handle 7 is fixedly connected with the chute 6 by threads.

Fixed pin 1, fastening bolt 2, butterfly nut 3, movable block 4, movable pin 5, chute 6, and handle 7 are all made of high-quality carbon structural steel and quenched to improve hardness. The butterfly nut 3 is not locked When tight, movable pin 5, movable block 4 and butterfly nut 3 can slide forward and backward along chute 6 as a whole.

The mode of work of the utility model is:

Disassemble the sealing end cover: unscrew the butterfly nut connected to the movable pin on the right side, adjust the position of the movable pin, so that the fixed pin and the movable pin can be inserted into the corresponding removal holes of the sealing end cover to be disassembled; tighten the butterfly nut on the right nut to prevent the movable pin from shaking; tighten the fastening bolt in the middle and the matching butterfly nut to increase the structural strength of the wrench; insert the fixed pin and movable pin into the corresponding disassembly hole of the sealing end cover; hold the handle and rotate the wrench , to unscrew the sealing end cap to be removed from its fixing seat; unscrew the wing nut on the right side, adjust the position of the movable pin, and then the sealing end cap can be removed.

Install the sealing end cover: unscrew the wing nut on the right side, adjust the position of the movable pin, so that the fixed pin and the movable pin can be inserted into the corresponding removal holes of the sealing end cover to be disassembled; tighten the wing nut on the right side to make the movable pin The pin cannot shake; tighten the fastening bolt in the middle and the matching butterfly nut to increase the structural strength of the wrench; manually screw the sealing end cover into the fixed seat; insert the fixed pin and the movable pin into the sealing end cover for corresponding disassembly hole; hold the handle and rotate the wrench to tighten the sealing end cover; unscrew the wing nut on the right side, adjust the position of the movable pin, and then the wrench can be removed.

For sealing end cap products of different sizes and different disassembly hole diameters, fixed pins and movable pins of different sizes can be configured and manufactured to meet the needs of disassembly and maintenance work.
