Description

Technical Field

[0001] This utility model relates to the field of mechanical transmission structure technology, and in particular to a micro flange screw spline integrated structure. Background Technology

[0002] Currently, the applications of flange screws and splines are becoming increasingly widespread. In the industrial field, flange screws can achieve stable power transmission and precise positioning control, improving production efficiency and reducing labor costs. In the machine tool field, splines can improve the stability and accuracy of machine tools, ensuring the quality of machined parts. At the same time, they can withstand large loads, ensuring the stability and safety of mechanical structures. With the current demand for smaller and lighter equipment and instruments, the demand for flange screws and splines is steadily increasing. However, most flange screws and splines on the market are split structures, meaning the spline and flange screw are two separate components. This not only results in large dimensions and space requirements, hindering miniaturization and cost savings, but also limits them to only one motion mode. Therefore, it is necessary to design a miniature integrated flange screw and spline structure. Utility Model Content

[0003] The purpose of this invention is to provide an integrated structure for miniature flange screw splines, which solves the problems of existing flange screw splines being separate structures, having large dimensions, requiring a lot of space, being unfavorable for miniaturization and cost savings, and having simple motion modes.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a miniature flange screw spline integrated structure, including a screw spline integrated shaft, a sealing groove, a shaft hole, and a spiral groove. A first groove is symmetrically formed on one end of the screw spline integrated shaft, in which spline balls from a flange screw assembly are tumblingly connected. The spline balls are tumblingly connected to a second groove, which is located on a spline sleeve. A first flange is welded to one side of the spline sleeve. A spiral groove is formed on the other end of the screw spline integrated shaft, in which screw balls from a flange screw assembly are tumblingly connected. The screw balls are tumblingly connected to a screw nut, which is threadedly connected to the screw spline integrated shaft.

[0005] As a further technical solution of this utility model, the spline assembly consists of a left end cap of the spline sleeve, a first screw, a spline sleeve body, a first flange, a right end cap of the spline sleeve, a second screw, a spline ball, and a second groove. The left end cap of the spline sleeve is fixedly connected to the other side of the spline sleeve body by the first screw, and the right end cap of the spline sleeve is fixedly connected to one side of the first flange by the second screw.

[0006] As a further technical solution of this utility model, the flange screw assembly consists of a screw nut, a second flange and screw balls, and the second flange is welded to the screw nut through a through groove.

[0007] As a further technical solution of this utility model, a sealing groove is provided on the spline sleeve.

[0008] As a further technical solution of this utility model, the first flange is provided with first through holes symmetrically.

[0009] As a further technical solution of this utility model, the second flange is provided with symmetrical second through holes.

[0010] As a further technical solution of this utility model, the lead screw spline integral shaft is provided with a shaft hole.

[0011] The miniature flange screw spline integrated structure provided by this utility model has the following advantages: The screw spline integrated shaft connects the flange screw assembly and the flange spline assembly onto a single shaft by symmetrically opening a first groove at one end and a helical groove at the other end. This eliminates the need for separate components, facilitating smaller size and less space requirements, thus saving costs in miniaturization and mass production. Applying external force to rotate the screw spline integrated shaft causes the spline balls, supported by the first and second grooves, to roll in the first groove, thereby driving the flange screw assembly to move linearly along the trajectory of the first groove. Simultaneously, it drives the screw balls, supported by the helical groove and screw nut, to roll in the helical groove, causing the flange screw assembly to move helically along the trajectory of the helical groove. This achieves both linear and helical motion modes on a single shaft, satisfying the diverse requirements of structural transmission. Attached Figure Description

[0021] Please see the appendix Figure 1 -Appendix Figure 5This utility model provides an embodiment of a miniature flange screw spline integrated structure, including a screw spline integrated shaft 1, a sealing groove 3, a shaft hole 5, and a spiral groove 7. A first groove 6 is symmetrically formed on one end of the screw spline integrated shaft 1. A spline ball 207 from the flange spline assembly 2 is tactilely connected to the first groove 6. The spline ball 207 is tactilely connected to a second groove 208, which is formed on the spline sleeve 203. A second groove 208 is welded to one side of the spline sleeve 203. A flange 204; the other end of the integrated screw-spline shaft 1 has a spiral groove 7, on which the screw ball 803 in the flange screw assembly 8 is rolled. The screw ball 803 is rolled to the screw nut 801, and the screw nut 801 is threadedly connected to the integrated screw-spline shaft 1; the flange spline assembly 2 consists of a left end cover 201 of the spline sleeve, a first screw 202, a spline sleeve body 203, a first flange 204, a right end cover 205 of the spline sleeve, and a second screw 206. The spline sleeve consists of a spline ball 207 and a second groove 208. The left end cap 201 of the spline sleeve is fixedly connected to the other side of the spline sleeve body 203 by a first screw 202, and the right end cap 205 of the spline sleeve is fixedly connected to one side of the first flange 204 by a second screw 206. The left end cap 201 and the right end cap 205 of the spline sleeve are used to seal the spline ball 207 in the spline sleeve body 203 and the first groove 6. The flange screw assembly 8 consists of a screw nut 801 and a second flange. The first flange 802 is composed of a ball bearing 803 and a screw nut 802. The second flange 802 is welded to the screw nut 801 through a through groove. A sealing groove 3 is provided on the spline sleeve 203. A first through hole 4 is symmetrically provided on the first flange 204. A second through hole 9 is symmetrically provided on the second flange 802. The second through hole 9 is provided to facilitate the connection of external equipment. A shaft hole 5 is provided on the integrated screw spline shaft 1. The shaft hole 5 is provided to reduce the mass of the integrated screw spline shaft 1 and the centrifugal force generated during rotation.

[0022] Specifically, in use, the flange key assembly 2 and the flange screw assembly 8 are first connected to a single shaft by symmetrically opening a first groove 6 at one end and a helical groove 7 at the other end of the integrated screw spline shaft 1. Thus, the flange key assembly 2 and the flange screw assembly 8 are no longer two separate components, easily achieving small size and minimal space requirements, which is beneficial for miniaturization and cost savings in mass production. Applying external force causes the integrated screw spline shaft 1 to rotate, driving the spline balls 207, supported by the first groove 6 and the second groove 208, to roll in the first groove 6, thereby causing the flange key assembly 2 to move linearly along the trajectory of the first groove 6. Simultaneously, the screw balls 803, supported by the helical groove 7 and the screw nut 801, roll in the helical groove 7, causing the flange screw assembly 8 to move helically along the trajectory of the helical groove 7. This achieves both linear and helical motion modes on a single shaft, meeting the diverse transmission requirements of this utility model.
