Description

Technical Field

[0001] The utility model relates to the technical field of mechanical disassembly tools, in particular to an adjustable double-hole three-jaw puller device. Background Art

[0002] A double-hole, three-jaw puller is a tool used for removing parts on shafts, consisting of a main body and three claws with two mounting holes. The adjustable double-hole, three-jaw puller is ideal for accommodating parts of varying outer diameters by adjusting the position or length of the claws. This improves the tool's versatility and efficiency, particularly when dealing with various axle parts on different car models during vehicle maintenance. The puller also precisely controls the direction of force based on the part's structure and installation, using an operating mechanism to precisely control the force to prevent damage to parts caused by improper tension. It is also safer than traditional disassembly methods, utilizing uniform force to minimize the risk of part splashing and personal injury, while ensuring stable operation. Furthermore, it can quickly adapt to different disassembly tasks, saving time on tool changes and reducing repetitive work caused by operational errors, effectively improving work efficiency.

[0003] The existing two-hole, three-jaw puller assembly primarily consists of a handle, a spiral rod, and claws. To operate, the top of the spiral rod is first aligned with the top hole at the end of the shaft. The claws are then adjusted and hooked onto the outer ring of the bearing, completing installation and positioning. The handle is then rotated, causing the spiral rod to rotate. Due to the threaded connection with the claws, this rotational motion is converted into linear motion by the claws, which then drive the bearing axially outward, ultimately removing the bearing from the shaft. Because the three claws are evenly distributed around the bearing, they create a stable fulcrum structure, ensuring uniform tension on the bearing and effectively preventing damage to parts due to uneven force.

[0004] The existing double-hole three-jaw puller device is used to install and fix the pulling claws by using bolts and nuts during use. When adjustment is required, professional tools such as wrenches are needed to disassemble and adjust the pulling claws. However, the professional tools need to be carried with them and workers need to use both hands to operate simultaneously during the disassembly and installation process, which not only wastes time but also reduces the work efficiency of the disassembly operation. Therefore, an adjustable double-hole three-jaw puller device is proposed to solve the above problems. Utility Model Content
