(2) Technical means In order to solve the above problems, the assembly jig structure for tapered roller bearings of the present invention comprises a processing box, an assembly auxiliary base is installed on the inner bottom of the processing box, and a rotary assembly head is rotatably attached to the top of the assembly auxiliary base. The upper part of the rotary assembly head is concave and has an assembly groove formed therein, a multi-position assembly table is provided in the center of the assembly groove, and a plurality of sets of arc-shaped clamping units are arranged on the upper part of the multi-position assembly table. A pressure cylinder is provided at the top of the inside of the processing box, and a bearing upper pressure plate is attached to the extension end of the pressure cylinder. The upper part of the bearing upper pressure plate and the extension end of the pressure cylinder are connected by an insert structure. Preferably, a drive motor is connected within the assembly assistant base, and an extension end of the drive motor is connected to the rotary assembly head, thereby driving and rotating the rotary assembly head. Preferably, a plurality of internal thread grooves 9 are formed on the inner upper portion of the multi-position assembly table. The arc-shaped clamp unit includes a threaded rod that is threaded into the internal thread groove, and an arc-shaped clamp block that is rotatably mounted on the threaded rod. A pressure nut is threadedly connected to the upper end of the threaded rod to press and fix the arc-shaped clamp block. Preferably, the arcuate clamping block is V-shaped. Preferably, the insert structure is composed of an upper connecting block connected to the telescopic end of the pressure cylinder and a lower connecting block connected to the top of the bearing upper pressure plate, and a fitting groove capable of accommodating the upper connecting block is formed in the lower connecting block, and pin holes are formed in both the fitting groove and the upper connecting block.

[0004] (3) Beneficial Effects Compared with the prior art, the advantages of the present invention are as follows: In this invention, by providing a rotating assembly head and a multi-position assembly table, control settings during assembly can be easily made, and clamp adjustments can be easily made according to bearing specifications. Furthermore, because the upper bearing pressure plate and pressure cylinder are connected by an insert structure, the structure is simple and easy to operate, and the upper bearing pressure plate can be quickly replaced to suit tapered roller bearings of different specifications without the need to adjust the entire jig, which increases the versatility of the jig and reduces capital investment costs.
