Description

Crimping tool

Technical Field

The utility model belongs to the technical field of tools, and particularly discloses a crimping tool.

Background

In some automobile parts, a gear assembly formed by combining a gear and a ring gear is often used by being mounted in a component, such as a gear assembly in a transmission. Therefore, after the gear and the gear ring are machined, the gear and the gear ring are matched together in a compression joint mode, namely, the connecting section axially protruding from the gear is pressed into an inner hole in the combined gear ring and fixed in an interference fit mode, and the coaxiality of the two parts at the same time needs to be ensured in the assembling process.

When the gear and the gear ring are in compression joint, a compression joint tool shown in figure 1 in the attached drawings of the specification is mostly adopted to mount the gear 30 and the gear ring 31, the gear ring 31 is placed on the base 10, the end face of the gear ring 31 is in contact with the guide shaft 14, then the gear 30 is placed into the guide shaft 14, and then the gland 15 is placed into the guide shaft; at this time, pressure is applied to the gland 15, the pressure is sequentially transmitted to the gear 30 and the guide shaft 14, the gear 30 and the guide shaft 14 compress the spring 13 to move downwards, the gear 30 moves downwards to be pressed into the gear ring 31, after the gear 30 and the gear ring 31 are in compression joint, the guide shaft 14 is restored to the original position under the action of the elastic force of the spring 13, and the gear assembly in compression joint can be obtained after the gland is taken out.

The tool is adopted to complete the compression joint of the gear and the gear ring, in order to keep the coaxiality of the gear and the gear ring, the gear and the gear ring need to be respectively aligned with the guide shaft, and the operation is complicated; before crimping, the gear and the gear ring are not in contact, and the gear ring are in contact under the action of pressure in the crimping process, so that the gear and the gear ring are easy to rub with each other to cause damage. In addition, the overall structure of the tool is complex, so that the manufacturing cost is high, the crimping operation is complex, and the crimping efficiency is low.

Compared with the prior art, the tool has the advantages of simple structure, simplicity and convenience in operation, low manufacturing cost and capability of completing the crimping process of the gear and the gear ring more quickly.

Furthermore, the pillar is provided with a shaft hole, and the pressure head is provided with a fulcrum shaft matched with the shaft hole.

Has the advantages that: realize through shaft hole and counter roll that the pressure head slides the setting from top to bottom with the prop is coaxial, make overall structure comparatively simple, it is comparatively convenient to use.

Further, a truncated cone-shaped connecting part is arranged between the pressing table and the support shaft, and the small-diameter end of the connecting part is connected with the support shaft.

Has the advantages that: to pressing the platform pressurization monkey, the fulcrum shaft slides downwards in the shaft hole, and the connecting portion of round platform can avoid pressing platform and pillar lock for after the crimping is accomplished, press the platform and conveniently take out.

Further, the pressing table, the connecting portion, and the support shaft are integrally formed.

Has the advantages that: the pressure head has simple structure, and is durable.

Further, the pressing table is provided with a circle of groove towards the connecting portion.

Has the advantages that: the processing of the pressing table and the connecting part is facilitated.

Furthermore, a circular truncated cone-shaped supporting platform is arranged on the boss.

Has the advantages that: the supporting platform can support the inner ring of the gear, so that the gear is placed more stably.

Further, the outer part of the strut is in clearance fit with the inner hole of the gear.

Has the beneficial effects that: the use can not be blocked, the crimping is more convenient and faster, and higher coaxiality can be ensured.

Further, the height of the shaft hole is larger than that of the fulcrum shaft.

Has the advantages that: the pressure of the pressure head is transmitted to the workbench to avoid the damage to the workbench in the process of supporting the shaft.
