Description of the new type [Technical field to which the new type belongs] This is related to the sowing operation—a kind of automatic feeding machine used for lathes to change the household structure, to improve the design of limiting the positioning of steel balls. Push #Improved [prior art] As shown in Figure 4, tf 'is the same as a lathe processing machine = its feeding device i 6 is mainly made of-clamp 丄 7 clamps the chuck 2 5 to be inserted into the lathe 2 4 Lathe 2 4 Chuck 2 5 = Advance to 23 to turn with the 24 spindle of the lathe at high speed. , 'Make the bar, t, bar 23-the end sleeve is placed on the clip 16 and 17 2 "of the feeding device 16 and clamps 25 of the lathe 24 and follows the lathe 2 so the feeding device 16 6 fixture 1 7 also rotates at a high speed, with the setting of = 'v, lost gear 1 7 and turn 1 8-there is a turn; device 19, wheel lion rod 18_ turn == the normal operation of the coupling set 16 & The 'coupling 19' made by moving and maintaining the feeding and loading tube 2 is composed of a shaft ^ which is screwed and fixed with the push rod 18, and is provided on the other end of the shaft tube 2-a screw 2 Supply ^, the corresponding rotation of the persimmon 8 formed between the rod 2 and the tube 2 0 rotates with minus 17. The movable property is shown in Figure 5 to Figure 6 'Because the spindle of the lathe is rotating at high speed, the axial clearance causes the steel ball 10 to appear In the state of radial movement, the relative forces between the tapered hole 71 of the steel ball 锥 tir tired rod 7 and the tapered hole 81 of the putter 8 are analyzed and compared. 'The author's research found that M274176 is a steel ball with a diameter of 10 In the moving state, the frictional force in the tapered hole 71 of the screw 7 and the tapered hole 81 of the push rod 8 causes a ring line contact B, which causes troubles of noise and high temperature, as shown in FIG. 7 In order to improve the function of the automatic feeding device of the lathe processing machine, it is necessary to improve the pusher of the automatic feeding machine. [New content] The main purpose of this creation is to solve the above problems and provide an automatic The improved structure of the push rod of the feeder is mainly provided on the shaft sleeve adjacent to one end of the steel ball with an accommodation portion, which is composed of an equal diameter section connected to a tapered end, and these diameter sections are used for the ball insertion system. It is used to limit the radial positioning of the steel ball, and the tapered end is used to limit the axial positioning of the steel ball, thereby limiting the effectiveness of the positioning of the steel ball. The second purpose of this creation is to set a large diameter of the end of the rod adjacent to the steel ball. The end surface is provided with a convex end and a single contact with the steel ball to make a single point contact, so as to avoid the occurrence of noise and high temperature, and to extend the useful life of the fixture. In order to achieve the aforementioned purpose, this creation is to provide an automatic feeder The improved structure of the push rod is mainly a rod that is rotatable in the shaft sleeve, and a steel ball is provided between the rod and the shaft sleeve, and the steel ball is provided on the shaft The accommodating part at one end is composed of an equal-diameter segment connected to a tapered end, thereby limiting the positioning of the steel ball. The above and other purposes and advantages of this creation are not difficult to be explained in detail from the following selected embodiments. Obtain a deeper understanding with the drawings. Of course, this creation may be different from some M274176 in some other parts or arrangements of other parts: but the selected embodiment is explained in detail in the financial specification and described in The structure is shown in the accompanying drawings. [Embodiment]-The diagram shown in Figures 1 to 2 of the 'm' muffler is the structure of the embodiment selected for the creation. This is for illustration purposes only and is not for patent applications. Limited by this structure. ^ First of all, this creation is an improved structure of the push rod of an automatic feeder, which is a rod 1 in a rotatable form inserted in the sleeve 2, and then the sleeve 9 Qin b rolling To block the bushings 1 and 3, a screwdriver 3 is provided at the other end of the rod 1 for the screwing of the clamp 1 7 and a steel ball 3 is provided between the rod 1 and the shaft sleeve 2. The steel ball 3 is provided The accommodating part 2 at the 2-end of the sleeve 2 is π, and the accommodating part 2 is connected to a cone by an equal diameter section 2 2 It is composed of 2 3. Therefore, by the structural design of the accommodation section 21 1 equal diameter section 2 2 connection-taper end 23 in this creation, when the lathe spindle is moving at high speed, it can avoid the steel ball 1 〇 radial movement State, thereby limiting the effectiveness of the positioning of the steel ball 3. Secondly, please refer to FIG. 3, in the present invention, a rod 丄 is provided adjacent to one end of the steel ball 3 with an end face ii having a larger diameter, and the end face 丄 丄 is provided with a convex end 12 and the steel ball 3 to abut. When rotating at a high speed, the convex end 12 and the steel ball 3 are brought into single point contact a, thereby avoiding the phenomenon of "squeak and high temperature" and extending the service life of the fixture 丄 7. In summary, the screw 1 is provided with an accommodating 邛 2 1 adjacent to one end of the ball 3, and the accommodating portion 21 is composed of an equal diameter section 2 2 and a tapered end 23. This creation uses these diameter sections 2 2 for the ball 3 to be placed and exposed on the end face of the aperture to limit the radial positioning of the ball 3, and the tapered end 2 3 is used to limit the axial positioning of the M274176 ball 3, thereby limiting The effect of the ball. The above-mentioned examples of the implementation of Sun Tian 丨, / Li, π 丄 A PF ^ 糸 are used to clarify the original creation, not to limit the original creation, so the number is the material of this creation. Furthermore, the replacement of the effective components should still be applied for according to the above detailed description.
