AI Technical Summary
The existing gear and gear shaft assembly fixture is prone to wobble when the locating pin descends, which affects assembly efficiency and accuracy. In addition, the gear and the locating groove have poor matching degree, which affects the assembly quality.
The locating pin, which adopts a two-section straight cylinder design, combined with ball bearings, clamping mold, and disc spring plate structure, achieves center positioning and stable clamping of the gear, thereby improving assembly accuracy.
It improves the balance and precision of gear and gear shaft assembly, ensuring assembly quality and efficiency, and is suitable for large-scale promotion.

Abstract
Claims
1. A gear and gear shaft assembly tool, comprising a base, a hollow spacer and a hollow fixing seat arranged in sequence from top to bottom, the inside of the spacer is provided with a positioning pin and a spring, and the fixing seat is provided with a positioning groove, characterized in that, The positioning pin includes a first straight cylindrical section and a second straight cylindrical section integrally formed. The second straight cylindrical section has at least two annular grooves spaced apart vertically on its contact surface with the inner wall of the pad. Several balls are arranged in the annular grooves. The fixed seat is provided with clamping molds distributed above the positioning grooves. The clamping molds include three clamping modules for engaging with the workpiece.
2. The gear and gear shaft assembly tool of claim 1, wherein, The clamping mold includes a square plate with a circular hole at its center. The clamping molds are evenly distributed around the circumference of the circular hole. Positioning holes are provided at the corners of the square plate and are inserted into positioning feet located on the top of the fixed base.
3. The gear and gear shaft assembly tool of claim 2, wherein, The square plate is provided with a pair of quick-release plates extending towards the sides of the fixing base. The bottom of the quick-release plates is provided with a buckle, and the side of the fixing base is provided with a slot that cooperates with the buckle.
4. The gear and gear shaft assembly tool of claim 3, wherein, The bottom of the square plate is provided with a positioning cylinder, which cooperates with the positioning ring groove provided on the top surface of the fixed base.
5. The gear and gear shaft assembly tool of any one of claims 1-4, wherein, The positioning groove is a countersunk groove, and a disc spring plate is provided at the bottom of the positioning groove. The center of the disc spring plate is arched upward and used to elastically support the workpiece.
6. The gear and gear shaft assembly tool of claim 5, wherein, The clamping module is provided with a connecting post, the connecting post is provided with a connecting hole, the connecting hole is provided with a bolt, and a limiting claw is provided between the bolt and the top surface of the connecting hole. The limiting claw rotates with the bolt and is used to limit the workpiece.
