Description of the invention (1) [Technical field to which the invention belongs] The present invention is a recirculation device in the cap of a ball screw. The reflow device f allows the balls in the ball screw to turn back and complete circulation and rolling. The nuts move against each other to transmit power. [Previous technology] ^ η Ball screw recirculation method is generally divided into external circulation method, internal f% method and end plug method, etc. Among them, the external circulation type recirculation system leads the balls out of the exhausted cap to complete the circulation, and the internal circulation The recirculating ball is directly recirculated in the internal thread of the tired head to complete the cycle. The end plug recirculation is to guide the ball of the screw = internal screw = from the end face of the nut to the hole of the nut to return the circulation in 20%. . The traditional end plug reflow is like the US patent us, which: the end plug 20 is inserted into the inner diameter of the nut 10 from the end face 16 of the nut 10, and the ball 70 in the screw groove 12 is guided to the return hole 38 to complete Recirculation cycle. The bottom surface 48 which is matched with the nut 10 and the screw U are two, the upper curved surface 56 is provided, and the end plug 20 is provided with a fixing hole 52 to fix the end plug on the 10, and the end plug 20 is also provided with a turning Path 70. Double turning path 62 and cover 68. Guide bow. And two ^ declining beads. This traditional ball screw end plug reflow 2 = 2 4 ° J coordination 'makes its structure complex, so-general: use == = Manufacture end plugs; secondly, because the end plugs have a high accuracy requirement due to the 'style fit', and the cost of making a 2 screw η 'cap is complicated, so the cost is also high; The reflow device of the processing pass is then fixed to the 蟫 _ Λ two screws. When assembling, the inlet must first be placed in the internal control of the screw head. 'Then put the ball and then rotate 1231845. 5. Description of the invention (2) The screw is inserted to make the above First, teeth must be used to apply end-plug backflow. The need for progress. 1. The end plug reflow method of the first ball screw is improved. [Objective of the invention] The main purpose of the present invention is to reflow the device directly into the nut ball screw, which requires teething, and the nut and the ball screw are assembled. The complexity of non-mesh body processing is reduced. [Summary of the invention] The nut of the ball screw is engaged to move it to cause relative movement; there is a ball roller screw between the two of the present invention. Its nut mainly includes a screw: ::, the nut body of the ball with a plug-type reflow method. In addition to its inner diameter; there is an internal recirculation method of the present invention: for the purpose of the invention mentioned above, 螺, 彳 径向 & ia # 二 = machine through hole outside the circle is provided with a plurality of radial hole nut A reflux device is placed outside the body. = Direct * = Sleeve into =, then insert the ball into = and then plug into the return device, this design can eliminate the need for teeth. Second ’To reduce the complexity of the nut body ’s security,
