Description

Technical Field

[0001] This utility model relates to the field of ball screw technology, specifically to a ball screw that is easy to clean. Background Technology

[0002] A ball screw is a mechanical transmission device consisting of a screw, a nut, and balls. It is primarily used to convert rotary motion into linear motion, or vice versa. Composed of a screw, nut, and balls, it is characterized by high efficiency, precision, and stability, and is therefore widely used in many fields.

[0003] In practical applications of ball screws, since the screw is often exposed and the balls are constantly rolling on it, dust falling on the screw can easily adhere to the balls, potentially causing adverse effects. Current methods for cleaning ball screws typically require removing the screw, then the nut, and finally the balls for cleaning. This is time-consuming, labor-intensive, and extremely inconvenient. Therefore, we have proposed a ball screw design that is easy to clean to address the aforementioned problems. Utility Model Content

[0022] 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.

[0023] Please see Figure 1-6 The present invention provides a technical solution: a ball screw that is easy to clean, including a screw 1, a nut seat 2 sleeved on the screw 1, a spiral semi-circular ball raceway on the outer side of the screw 1 and the inner side of the nut seat 2, and balls 9 arranged in the ball raceway, and a connecting seat 16 fixedly provided on the outer side of the nut seat 2.

[0024] The nut seat 2 has a ball return raceway 10 and the sealing part has a deflection raceway 12. The ball return raceway 10, the deflection raceway 12 and the ball raceway inside the nut seat 2 are connected to each other, so that the ball 9 can circulate normally in the ball return raceway 10, the deflection raceway 12 and the ball raceway.

[0025] Furthermore, a through-hole 15 is provided at the connection between the ball raceway and the return ball raceway 10 in the nut seat 2. The through-hole 15 is aligned with the deflection raceway 12 on the inner side of the sealing component to ensure that the ball 9 is in a normal circulating rolling state in the nut seat 2, thereby ensuring the normal operation of the ball screw. The opening size of the through-hole 15 is larger than the diameter of the ball 9, which makes it convenient for the ball 9 to be directly removed through the through-hole 15, thereby facilitating the cleaning of the ball screw without completely disassembling it.

[0026] Both ends of the nut seat 2 are equipped with sealing components. The sealing components consist of sealing component 1 3 and sealing component 2 4. The sides of sealing component 1 3 and sealing component 2 4 are provided with reinforcing edges 7. The reinforcing edges 7 are connected to each other by bolt 2 8 and nut.

[0027] Furthermore, both the first sealing component 3 and the second sealing component 4 are integrally provided with snap-fit ​​edges 5 on their sides. The snap-fit ​​edges 5 are located on the outer side of the end of the nut seat 2 and are connected to the nut seat 2 by bolts 6 to ensure that the positions of the first sealing component 3 and the second sealing component 4 on the nut seat 2 are fixed.

[0028] Furthermore, a locking block 14 is provided on the inner side of the locking edge 5, and a locking groove 11 is provided at the end of the nut seat 2. The locking block 14 and the locking groove 11 are aligned and locked together, which strengthens the stability of the connection between the sealing component 1 3 and the sealing component 2 4 on the nut seat 2.

[0029] Furthermore, the inner sides of the sealing component 3 and the sealing component 4 are provided with cleaning blocks 13, and the inner side of the cleaning block 13 has a protrusion that matches the ball raceway on the lead screw 1, which can clean the lead screw 1 in a timely manner to reduce the adverse effects of dust and impurities falling on the lead screw 1 on the balls 9.

[0030] Furthermore, the cleaning block 13 is made of hard rubber to ensure its safe and normal working condition. The cleaning block 13 is detachably connected to both the first sealing component 3 and the second sealing component 4, making it easy to replace the cleaning block 13 and thus ensuring the normal cleaning of the lead screw 1.

[0031] Specifically, when using this easy-to-clean ball screw, the moving workpiece is first connected to the connecting seat 16, the motor drives the screw 1 to rotate, and the ball 9 rolls spirally in the ball raceway that cooperates with the screw 1 and the nut seat 2. Through the deflection raceway 12 and the return ball raceway 10, the ball 9 rolls in a cycle. During the rolling of the ball 9, the nut seat 2 can be displaced on the screw 1 without rotating, thus realizing the movement process required to move the workpiece.

[0032] When the ball screw needs to be cleaned, by removing bolt 16 and bolt 28, the sealing parts 13 and 24 can be separated from the nut seat 2, and the ball 9 inside the nut seat 2 can be removed through the openings 15 on both sides; after the ball 9 is removed, the screw 1 and the nut seat 2 are simply connected, and the area between the screw 1 and the nut seat 2 can be flushed and cleaned.

[0033] After cleaning, the ball bearing 9 is inserted into the ball raceway and return ball raceway 10 through the through port 15. Then, the snap-fit ​​edge 5 on the sealing part 1 3 and the sealing part 2 4 is connected to the slot 11 on the nut seat 2 through the snap-fit ​​block 14 to achieve the pre-connection of the sealing part 1 3 and the sealing part 2 4 with the nut seat 2. Then, the two ends of the nut seat 2 are fixed to the sealing part 1 3 and the sealing part 2 4 through the bolt 1 6. Finally, the reinforcing edge 7 on the sealing part 1 3 and the sealing part 2 4 is fixed through the bolt 2 8 and the nut to ensure the stable working state of the sealing part.

[0034] Once the sealing component is in position, its inner deflection raceway 12 will stably align with the return ball raceway 10 and the ball raceway, allowing the balls 9 to circulate normally and ensuring the normal operation of the ball screw in the future.

[0035] The above describes the usage process of the ball screw. Any content not described in detail in this manual is existing technology known to those skilled in the art.

[0036] Although the present invention 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 invention should be included within the protection scope of the present invention.
