[0016] Example Reference Figure 1-4As shown, this utility model discloses a device for improving the surface finish of bar stock, including a clamping machine tool 10 and a rolling module 20. The clamping machine tool 10 is used to fix the bar stock, and the surface of the bar stock is coated with machine oil. The rolling module 20 is used to roll the outer surface of the bar stock to increase the surface finish. Specifically, the clamping machine tool 10 includes a three-jaw chuck 101 rotatable at one end and a tail cone 102 at the other end. The rolling module 20 is movably disposed on one side of the line connecting the three-jaw chuck 101 and the tail cone 102. The three-jaw chuck 101 clamps one end of the bar stock, and the tail cone 102 abuts the other end of the bar stock. The rotation of the three-jaw chuck 101 drives the rotation of the bar stock.

[0017] Furthermore, the clamping machine tool 10 is further provided with a first slide rail along the length direction, and a second slide rail perpendicular to the first slide rail is installed on the fixed base 201. The fixed base 201 can move back and forth along the first slide rail, driving the clamping machine tool 10 to move along the length direction of the bar stock. The fixed base 201 moves along the second slide rail to make the rolling module 20 approach or move away from the bar stock.

[0018] Reference Figure 3-4 As shown, the rolling module 20 includes a fixed base 201, on which a fixed rod 202 is installed. Specifically, the fixed base 201 has a square hole, and a locking bolt is provided in the square hole. The fixing rod 202 is locked in the square hole by the locking bolt. The fixing rod 202 passes through the square hole and is fixed in the square hole by the locking bolt, thus realizing the quick installation of the fixing rod 202.

[0019] Reference Figure 3-4 As shown, the fixing rod 202 has a U-shaped groove 2021, and the bearing 2022 is installed in the U-shaped groove 2021. Specifically, the fixing rod 202 has a shaft hole perpendicular to the U-shaped groove 2021. The pin passes through the shaft hole and the bearing 2022 to install the bearing 2022 in the U-shaped groove 2021. One end of the pin is fixed by a snap-fit. The bearing 2022 is rotatably installed in the U-shaped groove 2021 by the pin. The snap-fit ​​method at one end of the pin facilitates the replacement of the bearing 2022.

[0020] Reference Figure 3-4As shown, the fixing rod 202 is fitted with an end cap 2023 at one end of the opening of the U-shaped groove 2021. The end cap 2023 has a funnel hole 2025. A ball bearing 2024 is installed inside the end cap 2023. The end face of the bearing 2022 abuts against the ball bearing 2024, and the ball bearing 2024 protrudes from the funnel hole 2025. Specifically, the large-diameter end of the funnel hole 2025 faces the bearing 2022. The end cap 2023 is threaded onto the fixed end. The ball 2024 is placed in the funnel hole 2025. The end cap 2023 is locked to the end of the fixing rod 202 at the opening of the U-shaped groove 2021. The bearing 2022 abuts against the ball 2024, causing the ball 2024 to protrude from the funnel hole 2025. When the ball 2024 rotates, the bearing 2022 can also rotate. The fixing rod 202 presses the ball 2024 against the surface of the bar stock. The rotation of the oiled bar stock drives the ball 2024 to roll along the surface of the bar stock. The rolling of the ball 2024 along the surface of the bar stock increases the surface smoothness of the bar stock.

[0021] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
