Description

Technical Field

[0001] This utility model relates to the field of ball screw tooling, and more particularly to ball screw roll forming positioning tooling. Background Technology

[0002] A ball screw is a component consisting of a screw, nut, steel balls, and preload plates. By having the steel balls roll between the raceways of the screw and nut, it efficiently converts rotary motion into linear motion, and features low friction, high precision, and reversible transmission.

[0003] The ball screw has many rolling balls between the screw shaft and the screw nut, which reduces the driving torque to less than 1 / 3 compared to the traditional sliding screw pair, resulting in higher motion efficiency.

[0004] In existing ball screws, the screw shaft is typically rolled by hand, with the raw material being placed into the rolling machine. Due to the instability of hand operation, the raw material is prone to shifting during rolling, affecting the rolling effect. To address this issue, a ball screw rolling forming positioning fixture is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a ball screw rolling forming positioning fixture, which aims to improve the poor forming effect when performing rolling operations in the prior art.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figure 1 and Figure 2This utility model provides an embodiment of a ball screw rolling forming positioning fixture, including a base 7. The base 7 is configured to provide support for the sliding of a guide plate 10. Multiple rollers 13 are evenly distributed on the base 7. Rollers 13 are rotatably connected to the inner wall of the base 7, and the rollers 13 provide guidance for the movement of the manufacturing material. The rollers 13 facilitate the movement of the manufacturing material. Two guide plates 10 are slidably connected to the inner wall of the base 7, arranged symmetrically in an L-shape. The guide plates 10 guide the movement of a movable seat 8. A movable seat 8 is fixedly connected to the upper end of the guide plate 10. The movable seat 8 is equipped with rollers 13 and moves synchronously with the movement of the guide plates 10. A guide block 12 is elastically connected to the upper inner wall of the movable seat 8 via a spring 11. Block 12 moves upward, compressing spring 11. Guide block 12 guides the movement of insertion rod 9. The outer wall of guide block 12 is slidably connected to the upper inner wall of movable seat 8. One end of spring 11 is fixedly connected to the upper outer wall of guide block 12, and the other end of spring 11 is fixedly connected to the inner wall of movable seat 8. Insertion rod 9 is fixedly connected to the outer wall of guide block 12. The outer wall of insertion rod 9 is slidably connected to the inner wall of movable seat 8. The lower outer wall of insertion rod 9 is engaged with the inner wall of insertion hole 14. Insertion hole 14 is provided on the upper inner wall of base 7. Insertion hole 14 provides support for fixing insertion rod 9. Positioning block 15 is fixedly connected to the rear outer wall of movable seat 8. Positioning block 15 is engaged with the front inner wall of base 7 and plays a positioning role. An adjustment component is provided at the bottom of base 7. The adjustment component is used to adjust the height of base 7.

[0031] Reference Figure 1 and Figure 3The adjustment assembly includes a vertical rod 16, with a positioning hole on the inner right side wall of the vertical rod 16. The upper end of the vertical rod 16 is fixedly connected to the bottom end of the base 7. A vertical rod 2 4 is slidably connected to the outer lower side wall of the vertical rod 16, providing support for the sliding of the vertical rod 16. A block 5 is elastically connected to the outer right side wall of the vertical rod 2 4 via a spring 2 6. The block 5 is engaged with the inner wall of the vertical rod 16, fixing the vertical rod 16 to the vertical rod 2 4. When an external force moves the block 5 to the right, it stretches the spring 2 6. After the external force is removed, the elastic force of the spring 2 6 causes the block 5 to move to the left. The outer left side wall of the block 5 is slidably connected to the base 7. On the right inner wall of vertical rod 2 4, the left outer wall of the insert 5 is engaged with the inner wall of vertical rod 1 16. One end of spring 2 6 is fixedly connected to the right outer wall of vertical rod 2 4, and the other end of spring 2 6 is fixedly connected to the left outer wall of insert 5. A rotating block 3 is rotatably connected to the lower inner wall of vertical rod 2 4. The rotation of rotating block 3 is used to adjust the position of vertical rod 2 4 on fixed block 2. The height is finely adjusted by setting rotating block 3. The lower inner wall of rotating block 3 is threadedly connected to fixed block 2. Fixed block 2 is slidably connected to the lower inner wall of vertical rod 2 4. Fixed block 2 has a threaded groove. The bottom end of fixed block 2 is fixedly connected to mounting plate 1.

[0032] Working principle: The tooling is fixed by the mounting plate 1. The insertion rod 9 is moved upward by external force, so that the lower side of the insertion rod 9 leaves the inner wall of the insertion hole 14. After the insertion rod 9 leaves the inner wall of the insertion hole 14, the fixation of the moving seat 8 is released, and the moving seat 8 can be moved forward to place the manufacturing material on the base 7. Then the moving seat 8 is moved back to its original position by releasing the insertion rod 9 to lock the position of the moving seat 8 in the insertion hole 14, thus positioning the manufacturing material. Then the moving insert 5 is used to release the fixation of the vertical rod 16. The vertical rod 16 is moved to adjust the height of the manufacturing material. After the adjustment is completed, it is fixed by the insert 5. Then the rotating block 3 is rotated. By rotating the rotating block 3, the position of the vertical rod 4 is adjusted, thereby fine-tuning the height of the manufacturing material and facilitating the positioning of the manufacturing material.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
