New Description·· 【New Technical Fields】 This creation provides a reflow element for a ball screw, in particular a reflow element that is buried in the reflow element by means of a buried return element. Simple application 'suitable to simplify the reflow element configuration and easy assembly. [Previous technology] According to the continuous development and improvement of precision feed system, linear drive technology and its products have become the most important materials in many precision machines. A wide variety of linear mechanism products have been widely used in life, processing 1 Wei and high-tech 槿 ' ' ' ' ' Linear slippery, ball screw, etc.; although linear machine; what development is very expected, but (4) make (four) still have to Improvements have therefore generated many problems that still need to be developed, and related support = need for more stable and quiet high-precision manufacturing industry tools (eg, Japanese yen processing equipment, CNC equipment, etc.), some technical blind spots of the organization Add research and development improvements. , first, please refer to the thread groove (i 〇^>4t shown in Figure 5 to Figure 8), see the ball screw in the 7 product for the nut (i Q Μ (not -), In this method (4), the nail (4〇) of the reflow element (4) is installed in the grooving groove (1〇2), and the thread groove of the 5 M314279 bead screw is rolled ( And turning from the rolling element (not shown) of the return channel (1 〇^), into the recirculation action; entering the reflow element (4) at the other end, thereby completing the important meaning of the reflow element (4) Sexuality, but because of the complicated steps in the installation, it is not easy to install. The reason is that the reflow element (4) and the locking nut (2 Ί ) are strong, and J 1 ) is a separate installation. The accommodating groove (211) is additionally provided, and the accommodating groove (2 work 1) is mainly a fixed locking nut (21), so that the locking nut (21) disk screw (60) can be screwed smoothly. If there is no setting of the groove (2] ίι), the locking nut (21) will rotate with the screw (6〇), and the purpose of fixing the reflow element (4) cannot be achieved. The reflow element (4) and the locking nut (21) are separately provided with the following disadvantages: First, because the valley groove (2 1 1 ) is provided, the reflow element (4) is complicated in appearance, and the processing is not easy to be relatively The manufacturing cost increases and affects the strength of the reflow element. Secondly, when the reflow element (4) is small, the relative locking nut '(2 1 ) is also smaller in size, so the fixed locking nut (2) 1) It is not easy to fit in the receiving groove (2 1 1 ), so the installation time is relatively long. Third, the screw (2 2 ) passes through the first screw through hole (1 〇 4 ) and the second screw through hole (2 2 1 ), if it is not just screwed into the threaded groove of the locking nut (2 1 ), the locking nut (2 1 ) will be thrown out by the screw (2 2 ) and will fall. 6 M314279 Fourth, the receiving groove (2 1 1) of the reflow element (4) must be designed with the tolerance of the locking nut (2 1 ). Therefore, the conventional reflow element is structurally inaccessible. Allowing the user to facilitate the purpose of the female I, further extending the time for assembling the reflow element, and relatively increasing the manufacturing cost, and the external structure is complicated, and the processing is not Therefore, it is necessary for further improvement. [New content] Based on the shortcomings of the above-mentioned conventional reflow components, the creator has been researched and improved, and the original creation of the following creations can be achieved. The main purpose is to provide a reflow element that can quickly mount the slot fixed to the end face of the nut, shorten the process time and reduce the cost, and improve the efficiency of the ball screw production capacity. The second purpose of this creation is to simplify the reflow element. The shape is convenient for the mold design, and the strength of the reflow element can be increased to extend the life; ☆ For the purpose of the above creation, the improvement of the creation is a ball screw back μ element, wherein the ball screw system includes a shaft a nut to the return channel and a number of rolling elements that are positioned to be fixed to the ends of the nut (the rolling element is connected from one end of the spiral groove of the screw to the return element through the end) The return channel is connected to the reflow element of the other end face and is coupled with the other end of the spiral groove of the nut. The reflow element is formed by: The injection molding method is to insert the locking nut into the mold 7 M314279 before the injection molding, and the locking nut is coated on the surface of the reflow element to combine the locking nut with the reflow element, which not only simplifies the reflow The outer shape of the component improves the strength of the reflow component, and when assembling the reflow component, it is only necessary to fix the reflow component to the slot on both end faces of the nut, and then screw the screw into the screw through hole and the locking nut to lock the screw This can save a lot of installation steps, and achieve the goal of reducing the cost and shortening the process time.
