Description

Technical Field

[0001] This utility model relates to the field of shaft pin fillet machining technology, specifically to a shaft pin fillet machining device that facilitates adjustment. Background Technology

[0002] The core function of rounding the corners of a shaft pin is to optimize its performance and lifespan. Firstly, it eliminates sharp edges at the pin ends and steps, preventing scratches to mating parts (such as holes and bushings) or operators during assembly, thus improving assembly safety and smoothness. Secondly, it disperses stress concentration. Shaft pins are subjected to tensile, compressive, or shear forces during operation, and stress accumulation at sharp corners can easily lead to cracking. Rounded corners allow for even stress distribution, enhancing structural strength and fatigue resistance, and extending service life. Simultaneously, rounded corners reduce impact damage during assembly, protecting the pin's surface precision, reducing frictional loss, and improving contact with mating parts. Especially in rotational and reciprocating motion scenarios, this enhances transmission stability and prevents loosening caused by wear on sharp corners.

[0003] Existing technologies propose easy-to-adjust pin fillet machining equipment. When the pin needs to be machined with multi-directional fillets, stepped fillets, or fillets with special curvatures, it is impossible to adjust the angle of the machining component to adapt to different machining positions and angle requirements. This results in the need to frequently disassemble and reassemble the pin to adjust the machining position during the machining process. This is not only cumbersome and time-consuming, reducing production efficiency, but also prone to errors due to repeated positioning, affecting the consistency of fillet dimensions and machining accuracy, and causing problems such as assembly jamming, thus restricting the quality and performance of the pin products.

[0004] Therefore, we propose a machining equipment for easily adjusting the fillet radius of the shaft pin to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a tool for easily adjusting the fillet of a shaft pin, so as to solve the problem mentioned in the background art that the machining part needs to be frequently disassembled to fix the machining position of the shaft pin during the fillet machining process.

[0006] To achieve the above-mentioned objectives, the present invention adopts the following technical solution: This utility model provides a machine tool for easily adjusting the fillet radius of a shaft pin, including a worktable. A motor is fixedly installed on one side of the upper part of the worktable, and a processing table is installed on one side of the bottom part of the worktable. A U-shaped groove is opened on one side of the processing table, and connecting rods are symmetrically installed on one side of the U-shaped groove. One end of the connecting rod is rotatably connected to a movable ring, and a clamping ring is connected between the two sets of movable rings. A fixed ring assembly is provided at the midpoint of the rear end of the clamping ring, and a lead screw is inserted inside the midpoint of the rear end of the fixed ring assembly. A connecting plate is fixedly installed at the rear end of the lead screw. An elongated groove is opened inside the connecting plate, and a limit post is provided inside the elongated groove. The bottom of the limit post is fixedly connected to the surface of the turntable. A cutting tool is provided below the motor, and a U-shaped protective platform is provided below the cutting tool. The shaft pin body is provided inside the fixed ring assembly.
