No. 4,357,838. The installation procedure of the conventional method is as follows. Please refer to the figure - 'The nut (1) has a spiral groove in the inner hole (1 0). 1) and a groove (12) is radially recessed at both ends of the spiral groove (丄2) for providing a return end plug (13) installation. The female hole in the inner hole (10) is inserted into the liquid bead shown in Fig. 3. Please refer to Fig. 2, then the nut (the sleeve is inserted into the sleeve (A), and the sleeve (a) is (2). A tool. 3. As shown in Figure 3, the ball (2) is loaded into the nut (1) groove (11). At this time, the ball can be restrained by the sleeve (A) in the nut (1) spiral groove. (1 1) Medium' does not fall. 4. As shown in Figure 4, the nut (1) of the ball (2) will be mounted (:" increased over the screw (3) shoulder (3〇) and will Nut 5. As shown in Figure 5, the sleeve (A) will be synchronized along the inner hole (1 〇, 5 I31118 抽 pull out 'to make the ball (2). The teeth are engaged, so the ball (2) and the screw ( 3) Assemble. With the nut (1), it is known from the above that the assembly of the above-mentioned nut (1) and roller (3) must pass through: inner hole (1〇) = and screw ~ ball (U is loaded in the spiral groove (11) ) ^^ Sleeve (A) procedures must rely on (4) to dry (3) to test a lot of labor, in order to maintain a certain 钿酤 钿酤 shame and overall assembly time is quite time consuming and labor, resulting in = 叩 = efficiency And the quality can not be improved, it is more difficult to mention the economic benefits of ',, cognac into processing technology It is impossible to break through. Stomach is the result of the use of nuts (1,,,, Fen gamma 9, n installed and screw (3) group, 'so that the cost of high treatment 'quality, efficiency can not be improved' Based on years of professional experience and experience, the present invention has been continuously conceived and developed. [Invention] The main content of the present invention is to provide a ball screw for rapid beading, which is mainly provided in the nut-shaped circumference (four) a wire hole, the mounting hole is connected with the unloaded return hole between the two return end plugs, and the ball is filled into the return hole by the nut mounting hole by the ton supply ball, and overflows to the screw groove between the nut and the screw.俾 Keep the ball in the spiral groove, so that the screw and the nut can produce the phase shifting movement. After the ball is loaded, the mounting hole should be closed by the packing element, thereby making the ball arrangement easier and more economical. The principle and !311180, in order to remove the problem of conventional assembly, effectively improve the quality and productivity, and indeed provide a new and effective solution for the assembly of nuts, balls and screws. [Embodiment] The structure, features and other objects of the present invention can be further understood by the following description of the preferred embodiments as follows: Referring to Figures 6 to 10, the present invention includes a nut (i) and a lure ball (2). ), a screw (3), a return end plug (1 3 ); the nut (1) has an inner hole (丄〇) through which the screw (3) penetrates, and a hole (1 〇) in the nut (1) and The outer diameter of the screw (3) has a corresponding spiral groove (1 1 ) ( 3 1 ), and the nut (丄) is respectively formed with a return end plug (i 3 ) at both ends of the spiral groove (1 1 ). Press the grooving groove (1 2 ), and the return hole (1 4 ) is placed axially at the corresponding position of the two grooving grooves (1 2 ) 俾 at the return end plug (χ 3 ) and fixed in the grooving _ ( 1 2) After the 'reflow hole (1 4 ) and the spiral groove (1 1 ) (3 work) form a closed path for the circulation of the ball (2), characterized in that: the nut (1) is radially disposed on the outer circumference. The hole (1 5) having a larger aperture than the ball (2) is connected to the return hole (14) for providing the ball (2) by the nut (1) mounting hole (丄5) Fill in the return hole (1 4) and charge To the spiral groove (1 1 ) ( 3 1 ) between the nut (1) and the screw (3), the ball (2) is held in the screw groove (11) between the nut 7 1311180 '(1) and the screw (3) In (31), the screw (3) and the nut (1) can be moved relative to each other; ' = after the ball (2), the installation (15) must be closed with a packing element (; 6), the packing element (16) It can be made of metal materials such as copper or metal, or made of thermoplastic elastomer. The outer end is provided with a marking groove (i 6 〇), and the inner end is provided with an arcuate notch portion which is opposite to the return hole (14). (1 6 1 ), and in order to make the direction of the notch (1 6 1 ) indeed coincide with the returning hole (1 4 ), a positioning portion is provided on the outer circumference of the nut (1) (work 7: 'to be marked groove (16) 〇) After the positioning portion (17) is aligned, the direction of the notch portion (1 6 1 ) is aligned with the return hole (i 4), and the outer diameter of the stuffing element (16) is tightly fitted to the mounting hole. 5) After the operator can illuminate the direction of the notch (丄6丄) by rotating the marking groove (160), it is convenient to adjust the direction of the notch (16 1 ) and the return hole. Relative to δ ' to make the ball (2) in the return hole (1) 4) When passing through this, there is no interference. Referring to the eleventh figure, it is another embodiment of the combination of the original packing element (丄6) and the thread (1), which is mainly in the hole (work) and has a female thread, and The outer diameter of the packing element (16) is provided with a male thread (1 6 2 )' which is not suitable for the purpose of making the packing element (1 6 ) can be used to mark the groove (1 60), so that the packing element (1) 6) screwed into the mounting hole (15), and in order to make the notch portion (丄6 1) direction 8 311180 and the return hole (14), it is provided with a positioning portion on the outer circumference of the nut (1) ( 17) After the groove (16〇) to be marked is aligned with the positioning portion, the direction of the notch Pp (1 6 1 ) is aligned with the return hole (1 4 ), and the screw is filled with the plug 4 (16) Easy-to-clear adjustment: Oral (1 6 1) direction, anyone can easily do it. Therefore, in accordance with the specific design of the present invention, the progress of the present invention can be understood from the following description. • The present invention only needs to thread the screw (3) into the inner hole of the nut (丄) (i: and 'locate the _(3), _(1) with the fixture, so that the nut (1), the screw (3) The spiral groove (ii) (3 i ) is matched, and the ball (2) can be filled into the mounting hole (15) to keep the return hole (14) and the spiral groove (11) (31). The ball (2), followed by the 'filling element (1 (one) closed mounting hole (1 5 )' so that the bead screw (4) is finished, any one of these assembly materials can easily be called: no need to use the sleeve auxiliary tool It can be carried out to greatly improve the time-consuming and labor-intensive situation in which the screw is pushed out by the conventional screwing screw. The present invention is naturally more convenient and quicker than the conventional manual work, so that the present invention can be exerted. The revolutionary high creation and Economic efficiency, making the production efficiency more efficient industrial use, it is indeed progressive. In addition, it is worth mentioning that the original packing element (16) is relatively located in the return hole (14), and the ball (1) is The return hole (1 9 1311180 is a no-load rolling, and the stress of the top pushing packing element (i 6) is quite small, because The packing element (1Θ) does not easily come out of the hole (1 5 ) due to the force applied by the ball (2), so the packing element (χ 6 ) is made of a thermoplastic elastic material, which is safe and flawless in use. As described above, the present invention has indeed provided an effective solution for the screw, nut and ball assembly, and has completely broken through the problem of low σσ夤 defect rate degradation in the reformed assembly production, and is a highly creative concept of technology. Applicable to the patent application, 提出 apply in accordance with the law. However, the above is only the present invention - the preferred implementation (four) has been, when not (4) is limited to the implementation of the invention _ 'that is, New Zealand's hair" The equal changes and modifications should be within the scope of the present invention.
