Description

Inner hole three-jaw hub detaching tool

Technical Field

The utility model relates to a wheel hub dismantles technical field, especially relates to a hole three-jaw wheel hub extracting tool.

Background

The model is 145K41-1, the size of the tire is 14.5x 5.5-6, the tire is a consumable, and the tire with serious abrasion can be replaced according to the flight condition of the airplane, namely the worn tire is disassembled from the upper surface of a hub, and a new tire is installed; in the tire dismounting engineering, no reference tool is available for assistance.

At present, in the disassembling process, a wheel hub can be disassembled from a tire only through manpower, a skid with the length equal to that of the wheel hub is placed on the back of the tire, feet are used on the skid to step on the two sides of the tire to loosen the inner surface of the tire and the wheel hub, the process is unsafe, a person stands on a wane as well, the gravity center is unstable, the person exerts downward force, the risk is further increased, the disassembling process is time-consuming and labor-consuming, and the efficiency is extremely low.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the defects existing in the prior art and providing a hole three-jaw wheel hub extracting tool.

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

the utility model provides a hole three-jaw wheel hub extracting tool, includes upper strut piece and lower strut piece, upper strut piece sets up in the top of lower strut piece, a plurality of fixed columns of fixedly connected with between upper strut piece and the lower strut piece, just the fixed extension board that is provided with two symmetries and sets up in top of upper strut piece, two fixed being provided with the diaphragm in top between the extension board, the internal thread of diaphragm is connected with the screw rod, the fixed three link that is provided with in the outside of screw rod bottom, the bottom fixedly connected with of screw rod supports the piece, and is three the inside of link all rotates and is connected with Z type connecting plate.

Furthermore, the outside threaded connection at screw rod top has the nut, just the outside fixedly connected with handle of two symmetry settings at screw rod top.

Further, the upper support piece and the lower support piece are both annular.

Furthermore, the bottom end of the Z-shaped connecting plate is provided with a hook claw which is folded inwards and tilted upwards.

Furthermore, the upper supporting piece, the lower supporting piece and the fixing column are all made of aluminum alloy materials.

Compared with the prior art, the beneficial effects of the utility model reside in that: this application can reach the work that wheel hub dismantled through manual operation, can realize high-efficient swift operation, ensures the work quality simultaneously, and can also obtain fine application on wheel hub of the same type, avoids the violence dismouting to cause the damage to wheel hub and tire.

Drawings

The accompanying drawings are included to provide a further understanding of the invention, and are incorporated in and constitute a part of this specification, illustrate embodiments of the invention, and together with the description serve to explain the principles of the invention.

Fig. 1 is a schematic view of the overall structure of an inner hole three-jaw hub disassembling tool provided by the present invention;

fig. 2 is the utility model provides a hole three-jaw wheel hub extracting tool's top view.

In the figure: 1. an upper support member; 2. a lower support; 3. fixing the column; 4. a support plate; 5. a transverse plate; 6. a screw; 7. a connecting frame; 8. a Z-shaped connecting plate; 9. hooking claws; 10. a resisting block; 11. a nut; 12. a handle.

Detailed Description

The technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiment of the present invention;

referring to fig. 1-2, an inner hole three-jaw wheel hub detaching tool comprises an upper supporting piece 1 and a lower supporting piece 2, the upper supporting piece 1 is arranged above the lower supporting piece 2, a plurality of fixing columns 3 are fixedly connected between the upper supporting piece 1 and the lower supporting piece 2, two symmetrical supporting plates 4 are fixedly arranged at the top of the upper supporting piece 1, a transverse plate 5 is fixedly arranged at the top between the two supporting plates 4, a screw 6 is connected to the inner thread of the transverse plate 5, three connecting frames 7 are fixedly arranged at the outer sides of the bottoms of the screw 6, supporting blocks 10 are fixedly connected to the bottom ends of the screw 6, and Z-shaped connecting plates 8 are rotatably connected to the insides of the three connecting frames 7.

The outside threaded connection at the top of screw rod 6 has nut 11, and the outside fixedly connected with at the top of screw rod 6 has two handles 12 that the symmetry set up, and handle 12 can be convenient for the staff to rotate screw rod 6.

The upper support 1 and the lower support 2 are both ring-shaped.

The bottom end of the Z-shaped connecting plate 8 is provided with a hook claw 9 which is folded inwards and tilted upwards.

The upper supporting piece 1, the lower supporting piece 2 and the fixing column 3 are all made of aluminum alloy.

The working principle is as follows: put the tire flat, rotate screw rod 6 through handle 12, screw rod 6 can drive Z type connecting plate 8 and reciprocate to according to the distance between tire diameter regulation collude claw 9, will collude claw 9 again afterwards and fill in the gap between tire and the wheel hub, and let collude claw 9 and place in wherein completely, make collude claw 9 and wheel hub can not become flexible, rotate nut 11 again this moment, nut 11 can make screw rod 6 reciprocate, and then with wheel hub and tire separation.
