New description: [New technical field] This creation is about a reflow cover fixing structure, which can be applied to the screw design without teething, especially the separation of the return cover and the fixing element. A variety of specifications, which can save the cost of re-opening. [Prior Art] By pressing, a ball screw is a transmission mechanism formed by rolling a steel ball around a spiral groove between a nut and a screw. Since the relative movement of the nut and the screw is achieved by the rolling of the steel ball, the friction can be reduced and the efficiency can be increased. In order to ensure that the steel ball moving between the nut and the screw does not roll out of the outside and is lost, it is necessary to have a design of circulating recirculation. At present, there are two conventional ball screw circulation recirculation designs, one is the design of the outer circulation, and the circulation loop of the steel ball is achieved by the elbow fixed outside the nut, and the elbow is called a return pipe; One is the design of the inner circulation, and the circulation loop of the steel ball is achieved by the return groove stuck inside the nut, and the groove is called a return cover. With regard to the conventional reflow cover assembly technique, please refer to Japanese Laid-Open Patent No. 2001-283901, as shown in Fig. 1, having a pair of protruding arms corresponding to the internal threads of the nut on the return cover 24, and Each of the two ends has a guiding wall 36. The return cover 24 is embedded by the inner side of the nut, so that the guiding wall 36 is elastically deformed along the end surface of the return hole. When the return cover 24 is positioned, the rear cover is utilized. The external force deforms the front end of the guiding arm 36 to embed the mating portion 39 of the M306288 on the return hole, thereby achieving a fixed effect. In this way, the assembly method adopted by the prior art is that the largest back cover 2 must be loaded inside the nut, so that it cannot be snailed in the teeth, and it is also complicated to be filled when the balls are assembled. - No, I will refer to the Japanese Patent No. 2GG3-11392, such as the flute. Back: Λ is a synthetic resin injection molded product, and the L-pattern is used on both sides to achieve a fixed effect.

The longitudinal direction of the return cover 4 in the figure is shown on both ends. There are two protruding shoulder portions 4 2 ' and in the short diameter direction of the return cover 4, each has a top abutting portion 43 on both end faces. The structure of the hole in the female hole I 1 of the screw-shaped female body has a cover groove 21 1 for the fitting of the cover plate 5 and a cane cover for fitting the protruding shoulder portion 4 of the return cover 4 The kneading groove 2 1 〇 and the inner end of the nut 2 corresponding to the cover reduction groove 2 丄 1 have a snap-engagement groove 2 for engaging the lug 52. Next, we will discuss the reflow cover fixing structure implemented in this creation. Please refer to Fig. 8 to Fig. 1 1 for the assembly steps of the creation. By using the pair of cover plates 5, the engaging grooves 5 ii are respectively mated with the elastic hooks 52 1 1 of one of the ears 5 2 , and then the card ears 2 2 are attached with flexible elastic pieces 5 2 2 on the side. On the top abutting portion 43 of the return cover 4, the other end of the elastic hook 5 21 is finally engaged with the latch engaging groove 212 at the inner side of the nut 2, so that the movement in the left and right and the up and down direction is restricted. Since the cover plate 5 1 of the fixing member 5 of the present invention and the structure of the lug 5 2 are provided by the structure of the nut mounting hole 21, the cover fitting groove for providing the cover plate 4 is provided. 21 1 is a reciprocating cover fitting groove 210 for fitting the protruding shoulder portion 4 of the reflow cover 4, and an inner side of the nut 2 corresponding to the cover fitting groove 2 11 has a buckle for the card ear 52 The combined card cover slot 2 i 2 allows the return cover 4 to be stably received in the mounting hole 2丄 to complete the fixed configuration of the entire return cover 4. In summary, the assembly structure of the reciprocating cover and the fixing component of the present invention overcomes the limitation that the conventional ball screw design must be out of the teeth, and the assembly crane which replaces the previous reciprocating cover tightly fits, and can solve the backlash because Manufacturing tolerances cause assembly problems. In addition to the above-mentioned ease of assembly, the return cover can also be used for a variety of specifications. And there is no similar creation or public publication in the same kind of products, so it meets the requirements of the new financial situation, but it is requested according to law. However, the above description of the embodiments is intended to be illustrative of the present invention and is not intended to limit the variation of the numerical values and the substitution of equivalent elements.
