Description

Technical Field

[0001] The utility model relates to the field of ball screw accessories, in particular to a reciprocating screw. Background Art

[0002] Reciprocating screws, also widely known as lead screws or screws, are an indispensable and important component in mechanical transmission. Its core function is to cleverly convert rotational motion into linear motion and vice versa. This magical conversion process is often achieved through the precise cooperation and interaction between the carefully designed spiral grooves on the screw and the matching nut. However, although reciprocating screws play a vital role in many application scenarios, their scope of use is limited to a certain extent by their length.

[0003] Specifically, once the length of the reciprocating screw is limited, it will directly affect the fields and scenarios in which it can be used. In some specific occasions that require a longer stroke, such as large-scale mechanical equipment, complex automated production lines, etc., standard reciprocating screws often cannot meet actual needs. At this time, users have to choose to specially customize the screw that meets their needs to ensure that it can meet specific working environments and conditions.

[0004] However, specially customized reciprocating screws are not perfect. First, the customization process often takes a long time, which not only affects the overall progress of the project, but may also cause delays in other related work. Secondly, since customized screws require special design and manufacturing, their cost is usually high, which undoubtedly increases the financial burden on users. In addition, since customized screws have poor versatility, once they are damaged or need to be replaced during use, users may need to re-customize them, which undoubtedly further increases the cost of use and time cost.

[0005] In summary, the length limit of the reciprocating screw does affect its application scope and effect to a certain extent. Therefore, when selecting and using a reciprocating screw, users need to fully consider their actual needs and scenarios and choose the most suitable screw type and length to ensure that it can meet their work needs. At the same time, for screws that need to be specially customized, users also need to make adequate preparations and plans in advance to ensure the smooth progress of the project.

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] like Figure 1 - Figure 5As shown, a reciprocating screw rod has a core component including a main rod 1, a nut seat 2, a cover 3, and an optional length-increasing rod 4 and an add-on connector 5. The main rod 1 is the basis of the entire assembly, and its shape and material are carefully designed and selected to ensure that it has good strength and stability. The nut seat 2 is fixed to the main rod 1 through a specific connection method to provide stable support for the entire assembly.

[0026] The cover 3 is fastened to the nut seat 2 by bolts, and a rubber gasket is provided at the connection, which not only enhances the firmness of the connection, but also ensures that the inside of the nut seat 2 will not be invaded by external dust and impurities. The design of the cover 3 also takes into account the convenience of maintenance and replacement, so that it can be easily opened and closed when necessary.

[0027] One end of the main rod 1 is designed with an add-on connector 5, which allows the main rod 1 to be connected to the length-increasing rod 4 according to actual needs. The add-on connector 5 includes a connecting rod 51 and a docking rod 56. The connecting rod 51 is connected to one end of the main rod 1 or the length-increasing rod 4, and a fixing rod 52 is fixed to its outer end. The outer end of the fixing rod 52 is further connected to a round tube 54 to form a stable structure. A first mounting hole 53 is also provided on the side wall of the fixing rod 52 for subsequent bolt connection.

[0028] The end faces of the length-increasing rod 4, the main rod 1, the connecting rod 51, the fixing rod 52 and the round tube 54 are all designed with a socket 55, into which a docking rod 56 is inserted. The side wall of the docking rod 56 is provided with a protruding strip 58, which cleverly prevents the length-increasing rod 4 and the main rod 1 from rotating after being connected. The docking rod 56 is also provided with a second mounting hole 57 that matches the first mounting hole 53. By inserting a bolt into the first mounting hole 53 and the second mounting hole 57, the docking rod 56, the length-increasing rod 4 and the main rod 1 can be firmly connected together.

[0029] It is worth mentioning that the connecting rod 51, the fixing rod 52 and the round tube 54 are designed as one body, which not only enhances the stability of the overall structure, but also simplifies the manufacturing and assembly process. The connecting rod 51 and the fixing rod 52 together form a stepped rod that matches the stepped hole 6, making the connection tighter and more stable. At the same time, the side wall of the fixing rod 52 forms a flat surface, and the two first mounting holes 53 are located exactly on this plane, which is convenient for accurate installation of the bolts.

[0030] The docking rod 56 and the protruding strip 58 are also designed in one piece, and the edge of the protruding strip 58 is designed in an arc shape, which not only enhances its structural strength, but also enables it to be smoothly embedded in the recessed groove of the side wall of the insertion hole 55. Two sets of second mounting holes 57 are distributed at both ends of the docking rod 56, which are convenient for alignment with the first mounting holes 53 and bolt connection.

[0031] In addition, the diameters of the first mounting hole 53 and the second mounting hole 57 are the same and both are threaded holes, which ensures the reliability and stability of the bolt connection. The seamless connection design between the length-increasing rod 4 and the main rod 1 ensures that the two can form a continuous and smooth spiral groove after connection, thereby ensuring the stability and efficiency of the entire assembly during operation. The reciprocating screw assembly achieves high functionality and stability through ingenious structural design and careful manufacturing process, providing a solid guarantee for the smooth operation of various mechanical equipment.
