New description: [New technical field] This creation is a kind of nut and its return cover. It is applied to the ball screw. == Others can be strengthened. [Prior Art] A is commonly used in the industry. A power conversion mechanism that converts rotation into linear _. The _ rod mainly consists of a rod body, a nut, a back _ and a plurality of balls. The ball is rolled in the thread groove between the rod and the nut to reduce the frictional resistance between the rod and the nut, resulting in a flatter rotation and accompanying movement, and providing a high speed operation speed. The application of ball screws is often used in a wide range of machine tools in the machine industry. Wires have excellent precision, reliability, and good component durability. In order to make the ball screw (10) ball not fall from the two ends of the nut and reciprocate and recycle in the nut, the design of the complement is mainly used. When the rod and the nut rotate relative to each other, the ball escapes from the end. Through the reflow knot ^ from the other - the money of the stalks and the thread of the stomach of the snails into the thread _ lion 'common touch structure is divided into Lai ring and Nei Xingze. The conventional internal circulation structure has a disadvantage, as shown in the "i-th diagram", which is a schematic exploded perspective view of a conventional ball screw reflow device. It is known that the reflowing crying 4 is fixed in the fixing groove 3 of the nut 30, and has the reflow groove 41, and the two sections adjacent to the thread groove 32 of the head 30 in the connecting system, so that the ball passes through the recirculation groove μ, and the crossing is 6 M308347. The thread groove 32 returns to its original running path to form a closed ball moving path, so that the ball continuously circulates in the thread groove 32 of a specific end portion without continuously moving along the thread groove 32. The cap fell out of the box. The Hui 40 series is embedded in the fixing groove depending on its shape, or is further extended to form the fixing wing 42 embedded in the thread groove 31 to enhance the fixing effect. However, whether the shape of the reflow device 40 is embedded in the fixing groove 31 or the fixing by the fixing wing 42 can only provide the fixing effect of the reflow device 40 along the axial direction of the nut 30, and the sowing method Provides a fixed effect along the radial direction of the nut, causing the return flow to displace along the axial direction of the screw at 30, affecting the return path of the ball. At the same time, although the fixing difference 42 can be reinforced, but because it is stuck in the thread groove, it will be displaced or deformed due to the pressure generated by the screw, so that the return groove 41 cannot be surely aligned with the thread groove 32. Matching, and further affecting the return path of the ball, the micro-inducing unnecessary noise and the high-speed is violent vibration, which in turn affects the positioning accuracy and repeatability of the tool machine. In severe cases, the rod is stuck. Become bad or reduce the life of each component. In addition, a matching backflower 4G_slot 31 is provided inside the nut, and a complicated multi-axis plus 1 procedure of jade length is also involved, so that the yield of the nut 3G is lowered and the cost is increased. [New content]. In view of the above problems, the main purpose of the present invention is to provide a material snail whose reflow n is used to enhance the effect of reflow on the ball nut and to process the nut. 7 M308347 Therefore, in order to achieve the above object, the present invention discloses a funnel structure of a ball nut, which comprises a peach cap body, a reflow n and a fixing member. The inner portion of the nut body is a thread groove, and two long grooves are formed in the inner wall of the nut body along the long axis direction, wherein the bottom of the long groove is formed with a perforation connecting the inner and outer sides of the nut body. The recirculator is fixed in the long trench, wherein the reflower has a plurality of recirculation grooves, which are coupled to the screw groove 'for forming a return path of the balls, and the reflower has _θ fixed

The fixing member is fixed to the fixing hole through the through hole, thereby fixing the reflux device in the axial direction and the radial direction of the nut body. The utility model has the advantages that the long groove which is opened along the axial direction of the nut body is used for the valley to reflow, and the reflow device is fixed to the long groove through the fixing member through the nut body, and can be axially and radially. The 岐 effect is achieved, so that the reflow device does not move 2 times. (4) The return groove of the return flow device and the thread groove of the body are surely engaged to 'maintain the ball rolling return path, so that the ball does not jump when moving, and the vibration wear and the sound are reduced. The problem. The shape of the long groove is also easier to process than the conventional groove (4), which reduces the manufacturing cost and the man-hour required for production. The features and implementations of the present invention are described in detail below with reference to the preferred embodiments. [Embodiment] The new ^ signing "2nd picture", "3rd picture" and "4th picture" are the reflow structure of the ball cage nut which is disclosed by the '^(4) riding, this-reflow structure The 8 M308347 includes a nut body 10 and a returnor 20. A threaded groove is formed in the nut body 1 Π to match the thread of the thread outside the screw 50. The ball (not shown) moves the passage to move the ball through the thread groove I to reduce the screw 50 and The relative rotation between the nut body 1〇 and the friction loss of the wire. On the inner wall of the nut body 10, a long groove 12 is formed along the long direction of the nut IU of the nut body, and the cross-sectional shape of the long groove 12 is rectangular, and the nut body 10 is The end extends to the other end, and its construction material 'simplifies the processing procedure. A perforation 13 is formed at the bottom of the long groove 12 to connect the inner and outer parts of the nut body 10 for a fixing member, for example, a countersunk screw 60 is inserted into the same 3 N* 'in the tooth hole 13 at the nut body 1〇 The outer portion is opened to form a counterbore 131. The diameter of the counterbore 131 is larger than the perforation 13 to accommodate the head 6 of the countersunk screw 60. After the countersunk screw 60 passes through the perforation 13, the countersunk head can be The head portion 61 of the screw 60 is hidden in the counterbore 131, and the countersunk screw 6 is prevented from protruding beyond the outer side of the nut body 10. Please refer to "5A", "5B" and "6th" for a perspective view of the reflow device 20. The reflow device 2 is a long rectangular type, and its cross-sectional shape can match the nut body. The long groove 12 of 10 causes the return valve 2 to be fixed in the long groove 12, thereby providing a ball-closed path in the thread groove 51. The reflow unit 20 has one or more recirculation tanks 21, for example, in the example of the present invention, the recirculation thief has four recirculation tanks, of course, the number thereof can be determined and the recirculation tank 21 can be The section type is the same as the U-phase M308347 of the thread groove, so that the ball smoothly passes through the return groove 21 and enters or leaves the thread groove 11. Please refer to the "Figure 4" for a schematic view of each section. The recirculation groove 21 is connected to the adjacent two thread groove n sections so that the balls pass through the return groove 21 and then return to the section of the originally operated thread groove 11 to perform the reflow movement. Further, by the connection pattern of the return groove 21 and the thread groove u, the thread groove 11 of the nut body 10 can be divided into a plurality of recirculation sections 11a, and the number of the reflow sections Ha corresponds to the number of the recirculation grooves 21. The two ends of each of the recirculation sections 11a are a reflow contact A and a reflow end point B, respectively, and are connected to both ends of the corresponding reflow tank 21. Each ball starts from the return point A of the reflow section Ua of the thread groove 11. When it reaches the recirculation end point B, it can pass through the reflow tank 21 and reach the reflow starting point a of the same h丄11a again, so that the ball is circulated in the single- Rolling in the reflow section 'does not continue to roll along the thread groove η and fall out of the nut body 1 (). 20 is more shaped - the fixing hole 22, the _ side rides through the nut. After the perforation of the ία, it is fixed in the fixing hole 22. This fixing hole 22 has a threaded engagement with the countersunk screw 6G to fix the countersunk screw in the fixing hole 22. When the reflow device 20 is placed at 12, the recirculators such as the fixing holes 22 correspond to the perforations μ of the nut body 1〇. 〃 帽 太 太 1 1 1 儿 儿 儿 儿 儿 儿 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 可由 可由 可由 可由 可由 可由 可由 可由 可由 可由 可由 可由 可由 可由 可由 可由 可由On the same day, the head 61 of the countersunk head screw 60 can be torn out of the nut body H).

Therefore, it is possible to ensure that the reflow and the joint state of the miscellaneous tank 11 are not changed, and that the ball is moved to the recirculation path, and the diameter, the stalk, the noise, the noise, and the noise are not caused. Moreover, the returning green 20 does not need to form an extension structure to the retort _ 2G in the inspection tank n. Therefore, the screw 5G does not generate a pseudo pre-pressure against the backflow of the recirculator 2 (), and the ball can be prevented from being deformed by the reflow of H 2G. The problem of changing the return path. - The novel type is fixed to the long groove 12 through the nut body 10 through a long groove (10) which is opened along the axial direction of the nut body 1 置, and a fixing member such as a countersunk screw 6 穿过 is passed through the nut body 10 . in. Among them, the countersunk screw can exert a fixed effect in both the axial direction and the radial direction, so that the reflow device 2 does not displace the lion, and at the same time, it is not subjected to the pseudo surface force of the screw 50, and the return groove of the reflow device 2 is ensured. It is surely engaged with the thread groove η of the nut body 10, and does not jump when the ball rolls back to the ball movement, and the problem of vibration, wear and noise is reduced. * The shape of the long groove 12 is also better than the fixing groove of the prior art. The type of state-s processing reduces the cost of production and the man-hours required for production. Although the best practice of this creation is revealed above, the age is not intended to limit the creation. Anyone who is familiar with the artist can make some changes and refinements in the spirit and scope of this creation. Therefore, this creation Patent Protection Model 11 M308347 is subject to the definition of the patent application scope attached to this specification.
