Description

Combined puller in restricted space

Technical Field

The utility model relates to the technical field of dismounting devices, in particular to a limited space combined puller.

Background

The puller is a disassembling tool for separating the bearing from the shaft and mainly comprises a rotating handle, a screw rod and a pulling claw. The bearing has two claws and three claws, and the main sizes are the length of the pulling claw, the distance between the pulling claws and the length of the screw rod so as to adapt to bearings with different diameters and different axial installation depths. The screw rod center is positioned in a shaft end center hole, the position of the pull claw is adjusted to enable the pull claw to be hooked on the outer ring of the bearing, and the pull claw drives the bearing to move outwards along the axial direction to be dismounted by rotating the rotary handle. At present, the puller disclosed by the prior art is large in size and has certain requirements on the field space when in use. Therefore, when the existing puller is used for disassembling fixed parts such as pins, bearings, gears and the like in a limited space, the use is inconvenient, and parts are easy to damage; even because the restriction in place makes current puller unable normal use, leads to dismantling the failure.

SUMMERY OF THE UTILITY MODEL

In view of the above, the utility model aims to solve the problems that in the prior art, the puller is inconvenient to use in a small space and is easy to damage parts in the use process; even the disassembly fails, so that the technical problem of high labor intensity of operators is caused, therefore, the utility model provides the limited space combined type puller, which can reduce the labor intensity, improve the working efficiency of maintenance, reduce the labor consumption and effectively avoid the accidental damage of parts.

In order to achieve the purpose, the utility model provides the following technical scheme:

a combined puller in a limited space comprises a pulling plate and a top plate;

the arm-tie is the U type, the arm-tie pass through the full knot bolt with the roof is connected, the front end of roof be provided with the full knot nut of full knot bolt looks spiro union.

Preferably, the thickness of each of the pulling plate and the top plate is 15-20 mm.

Preferably, the pulling plate and the top plate are both made of iron plates.

Preferably, the top plate is rectangular.

Compared with the prior art, the utility model has the following beneficial effects:

1. according to the limited space combined type puller provided by the utility model, the pulling plate is inserted into the rear side of a detached part, the top plate is arranged at the front end of the detached part, the pulling plate and the top plate are connected through four full-buckle bolts, the nut with a proper size is added on the side of the top plate, and the pulling plate is driven to move by fastening the full-buckle bolts, so that the detached part can be pulled;

2. the limited space combined puller has the advantages of simple structure, light weight, easy operation, low manufacturing cost and low later maintenance cost, is suitable for disassembling various types of bearings, and has good applicability.

Drawings

FIG. 1 is a schematic structural view of the present invention;

in the figure, 1, a pulling plate, 2, a top plate, 3, a full-buckled bolt and 4, a full-buckled nut.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention; it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments, and all other embodiments obtained by those skilled in the art without any inventive work are within the scope of the present invention.

In the description of the present invention, it should be noted that the terms "upper", "lower", "inner", "outer", "top/bottom", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention.

In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "disposed," "sleeved/connected," "connected," and the like are to be construed broadly, e.g., "connected," which may be fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

As shown in fig. 1, the present invention provides a limited space combined type puller, which comprises a pulling plate 1 and a top plate 2;

the pull plate 1 is U-shaped, the pull plate 1 through detain the bolt 3 entirely with roof 2 is connected, the front end of roof 2 be provided with detain the nut 4 entirely of bolt 3 looks spiro union entirely.

In the utility model, the thicknesses of the pulling plate 1 and the top plate 2 are both 15-20 mm.

In the present invention, the pulling plate 1 and the top plate 2 are both made of iron plates.

In the present invention, the top plate 2 has a rectangular shape.

In the structure of the utility model, the pulling plate 1 and the top plate 2 are preferably rectangular iron plates with the same size, the pulling plate 1 is provided with a U-shaped neutral position in the middle of the rectangle, the width of the U-shaped neutral position is slightly larger than the size of a detached shaft, the width of the U-shaped neutral position is slightly larger than the size of the detached shaft, and the four corners of the top plate 2 are provided with bolt holes, and the size of the bolt holes is matched with that of the full-buckle bolts 3.
