Description

Technical Field

[0001] This utility model relates to the field of ball screw technology, specifically a reciprocating ball screw for transmission. Background Technology

[0002] Reciprocating ball screws have advantages such as high transmission efficiency, sensitive operation, and good precision retention. They can eliminate axial backlash and have high axial stiffness, and have a wide range of applications. They are commonly used in machines that require precise positioning and are the most commonly used transmission components in machine tools and precision machinery. Their main function is to convert rotary motion into linear motion or torque into reciprocating force. They also have the characteristics of high precision, reversibility, and high efficiency. However, current reciprocating ball screws do not have a cleaning function, which makes it easy for dust and impurities to accumulate on the surface, affecting transmission accuracy and efficiency. Therefore, we propose a reciprocating ball screw. Utility Model Content

[0003] The purpose of this invention is to provide a reciprocating ball screw with a cleaning function, which solves the problem that current reciprocating ball screws do not have a cleaning function, resulting in the accumulation of dust and impurities on the surface, affecting transmission accuracy and efficiency.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a reciprocating ball screw, comprising a screw body, a nut on the outer surface of the screw body, a connecting block fixedly connected to the left end of the top of the nut, a housing on the left side of the connecting block, a telescopic rod fixedly connected to the top of the inner cavity of the housing, a spring sleeved on the outer surface of the telescopic rod, a movable block fixedly connected to the bottom of the telescopic rod, and a cleaning brush installed at the bottom of the movable block.

[0005] Preferably, the lead screw body includes a wear-resistant coating, a wear-resistant layer, a first high-strength layer, a second high-strength layer, and a substrate layer. The wear-resistant coating is a ceramic coating, the wear-resistant layer is a high-chromium wear-resistant alloy, the first high-strength layer is alloy structural steel, the second high-strength layer is high-strength alloy steel, and the substrate layer is carbon structural steel.

[0006] Preferably, the wear-resistant coating is applied to the outside of the wear-resistant layer, which is located outside the first high-strength layer.

[0007] Preferably, the first high-strength layer is located outside the second high-strength layer, and the second high-strength layer is located outside the substrate layer.

[0008] Preferably, a slot is provided on the left side of the connecting block, and an insert is fixedly connected to the right side of the housing. The insert is movably connected to the inner cavity of the slot. A threaded groove is provided on the top of the insert. A bolt is provided on the connecting block, and the bolt is threadedly connected to the inner cavity of the threaded groove.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model utilizes a nut that reciprocates on the lead screw body. Under the action of a spring and a telescopic rod, the cleaning brush remains in close contact with the surface of the lead screw body. As the nut moves, the cleaning brush continuously cleans the surface of the lead screw body, removing dust and impurities, ensuring transmission accuracy and efficiency. When maintenance of the cleaning brush or related components is required, the operator unscrews the bolt to separate it from the threaded groove, and then removes the insert from the slot. This allows for the separation of the housing from the connecting block, facilitating quick and easy subsequent maintenance. After maintenance, the device can be reconnected and used again by reversing the operation.

[0010] 2. This utility model enhances the wear resistance of the lead screw body surface through a wear-resistant coating. The wear-resistant layer significantly improves the wear resistance of the lead screw body and protects the internal structure. The first high-strength layer and the second high-strength layer give the lead screw body good strength and prevent the lead screw body from deforming due to external forces.

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.

[0014] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. Example

[0015] Please see Figure 1-4 As shown, this utility model provides a reciprocating ball screw, including a screw body 1, a nut 2 on the outer surface of the screw body 1, a connecting block 4 fixedly connected to the left end of the top of the nut 2, a housing 3 on the left side of the connecting block 4, a telescopic rod 8 fixedly connected to the top of the inner cavity of the housing 3, a spring 7 sleeved on the outer surface of the telescopic rod 8, a movable block 5 fixedly connected to the bottom of the telescopic rod 8, a cleaning brush 6 installed at the bottom of the movable block 5, a slot 9 on the left side of the connecting block 4, an insert 11 fixedly connected to the right side of the housing 3, the insert 11 being movably connected to the inner cavity of the slot 9, a threaded groove 10 on the top of the insert 11, and a bolt 12 on the connecting block 4, the bolt 12 being threadedly connected to the inner cavity of the threaded groove 10.

[0016] This technical solution uses nut 2 to reciprocate on lead screw body 1. Under the action of spring 7 and telescopic rod 8, cleaning brush 6 is always in close contact with the surface of lead screw body 1. As nut 2 moves, cleaning brush 6 continuously cleans the surface of lead screw body 1, removing dust and impurities, ensuring transmission accuracy and efficiency. When maintenance of cleaning brush 6 or related parts is required, the operator unscrews bolt 12 to separate bolt 12 from threaded groove 10, and then removes insert 11 from slot 9, which separates housing 3 from connecting block 4, allowing for convenient and quick subsequent maintenance operations. After maintenance is completed, the reverse operation can restore the device connection and continue use. Example

[0017] Based on Embodiment 1, this utility model is as follows: Figure 1-4 As shown, the lead screw body 1 includes a wear-resistant coating 101, a wear-resistant layer 102, a first high-strength layer 103, a second high-strength layer 104, and a substrate layer 105. The wear-resistant coating 101 is a ceramic coating, the wear-resistant layer 102 is a high-chromium wear-resistant alloy, the first high-strength layer 103 is alloy structural steel, the second high-strength layer 104 is high-strength alloy steel, and the substrate layer 105 is carbon structural steel. The wear-resistant coating 101 is applied to the outside of the wear-resistant layer 102. The wear-resistant layer 102 is located outside the first high-strength layer 103, the first high-strength layer 103 is located outside the second high-strength layer 104, and the second high-strength layer 104 is located outside the substrate layer 105.

[0018] This technical solution enhances the wear resistance of the lead screw body 1 surface through the wear-resistant coating 101, significantly improves the wear resistance of the lead screw body 1 by using the wear-resistant layer 102, protects the internal structure, and enables the lead screw body 1 to have good strength by using the first high-strength layer 103 and the second high-strength layer 104, thus preventing the lead screw body 1 from being deformed by external forces.

[0019] The working principle of this utility model is as follows: the nut 2 reciprocates on the lead screw body 1, and the cleaning brush 6, under the action of the spring 7 and the telescopic rod 8, always adheres tightly to the surface of the lead screw body 1. As the nut 2 moves, the cleaning brush 6 continuously cleans the surface of the lead screw body 1, removing dust and impurities, ensuring transmission accuracy and efficiency. When it is necessary to maintain the cleaning brush 6 or related parts, the operator unscrews the bolt 12 to separate the bolt 12 from the threaded groove 10, and then removes the insert 11 from the slot 9, which can separate the housing 3 from the connecting block 4, making subsequent maintenance operations convenient and quick. After maintenance is completed, the device connection can be restored by reversing the operation, and it can be used again. The wear-resistant coating 101 can enhance the wear resistance of the surface of the lead screw body 1. The wear-resistant layer 102 can significantly improve the wear resistance of the lead screw body 1 and protect the internal structure. The first high-strength layer 103 and the second high-strength layer 104 can make the lead screw body 1 have good strength and prevent the lead screw body 1 from being deformed by external forces.
