As shown in fig. 1-3, a spinning frame spindle aluminum sleeve combination structure comprises an aluminum sleeve cap 1, an aluminum sleeve 2 and a holder 3 in an injection molding process, wherein the aluminum sleeve cap 1 is arranged on the aluminum sleeve 2, an aluminum sleeve center hole 21 is formed in the top of the aluminum sleeve 2, the aluminum sleeve cap 1 arranged on the aluminum sleeve 2 is located right above the aluminum sleeve center hole 21, and the holder 3 is arranged on the aluminum sleeve 2. Correspondingly, the top end structure of the aluminum sleeve 2 is improved, the aluminum sleeve cap 1 is clamped at the top end of the aluminum sleeve 2, and the central hole 21 of the aluminum sleeve is hidden in the rod disc assembly without influencing the appearance and the size of the rod disc assembly; the designed total length of the rod-disk combination and the short and external conical surface formed at the top end are met. If the aluminum sleeve caps and the aluminum sleeves of different toner are combined at different spindle positions of the ring spinning machine, the efficiency of spindle position identification can be improved, and management is facilitated. The improvement of the top structure of the aluminum sleeve does not affect the overall process characteristics of the aluminum rod, only the numerical control machining program needs to be properly changed, but the length of the material needed by the process center hole can be saved, the process contents of transferring and cutting the process center hole are omitted, and the production efficiency is further improved. The rod-disk combination is internally provided with a reserved process center hole, so that the rod-disk combination can be used as a reference for the procedures of turning or grinding, straightening, measuring and the like in the manufacturing stage, and can be used as a reference for straightening the spindle rod-disk combination even after a period of spinning process, thereby prolonging the service life of the spindle.

Be provided with aluminium sleeve pipe block flange portion 11 on the aluminium sleeve pipe block 1, the recess 22 that is used for installing aluminium sleeve pipe block 1 is seted up at aluminium sleeve pipe 2 top, and aluminium sleeve pipe block flange portion 11 sets up on recess 22. Under the action of external force, the flange part 11 of the aluminum sleeve cap is strongly clamped into the groove 22 at the top end of the aluminum sleeve 2 by virtue of the characteristic of strong elastic deformation capacity of the flange part, so that the aluminum sleeve cap is prevented from flying off during high-speed rotation; the inner cylindrical surface of the aluminum sleeve cap 1 is tightly attached to the outer cylindrical surface of the aluminum sleeve 2, so that enough binding force is generated. Circular and cross reinforcing ribs are arranged inside the aluminum sleeve cap 1, so that the shock resistance and the deformation resistance of the top end short and outer conical surface are improved, and the deformation of the aluminum sleeve cap is reduced. The aluminum sleeve cap 1 is made of engineering plastics. The aluminum sleeve cap 1 adopts an injection molding process, so that the consistency of the sizes of parts is good, and the production efficiency is high; because the whole size of aluminium sleeve pipe block 1 is less, the material is engineering plastics, and self quality is lighter, probably the block is not concentric in aluminium pole center, probably the inhomogeneous of block self injection moulding has the centrifugal force that newly-increased off-centre and arouses the possibility, but to the comprehensive yaw of pole dish combination, vibration slightly relatively.

The injection molding type aluminum sleeve cap 1 is combined with the aluminum sleeve 2 to ensure that the designed total length is equal to the original rod-disc combination after the profile height H0, the excircle diameter D0, the length H1 and the spherical radius r1 of the top end of the short outer conical surface; the cross section of the flange part of the opening end of the aluminum sleeve nut cap 1 is semicircular with the radius R, the arc length A is uniformly distributed, and the circular and cross-shaped reinforcing ribs with the thickness of t can improve the impact resistance of the top short conical surface and the deformation of the top short conical surface. By means of the action of external force and the elastic deformation characteristic of engineering plastics, the aluminum sleeve is strongly clamped into the groove 22 with the width b and the diameter c at the top end of the aluminum sleeve 2, and the diameter D of the inner cylindrical surface of the aluminum sleeve cap 1 is tightly matched with the diameter D of the outer cylindrical surface of the aluminum sleeve.

The rod disk assembly is one of two parts (the other part is a spindle foot assembly) of an aluminum sleeve spindle, and comprises an aluminum sleeve, a spindle disk and a spindle rod. The upper part of the bobbin is kept to have enough friction force by the elasticity of the supporter 3 and the centrifugal force generated by rotation, the bobbin rotates synchronously with the rotating speed of the spindle, the lower part of the bobbin keeps or is suspended or contacts with the outer conical surface of the aluminum sleeve in a semi-friction state, and the bottom end surface of the bobbin contacts with the yarn separating disc to limit the axial position; the bobbin is not supported or rubbed except the bottom distance of the bobbin core, and the bobbin is only conveniently guided to be inserted. Generally, the production process related to the aluminum sleeve is a combination of blank preparation → rough finish machining of the tapered hole of the aluminum sleeve → drilling of the center hole of the process → rough machining of the shape of the aluminum sleeve → pressing of one end of the spindle rod into the tapered hole of the aluminum sleeve → pressing of the aluminum sleeve into the tapered hole of the spindle disk → finish machining (finish grinding) of the shape of the aluminum sleeve → detection, alignment → cutting of the center hole of the process, top shaping of the short outer tapered surface → milling of trisection holder concave hole → loading of the holder spring, holder → formation of the spindle disk of the aluminum sleeve.

The production process of the aluminum sleeve 2 is basically consistent with the original process, after a center hole is drilled by a drilling machine, the center hole is used as a support of one end and is tightly propped when the appearance of the aluminum sleeve 2 is processed, the bending and the deviation of the rotation center of the aluminum sleeve caused by the transverse component force of cutting force are prevented, and the aluminum sleeve is used as a mechanical processing process measure for improving the full-length straightness of the aluminum sleeve, because the top end of the aluminum sleeve 2 needs to be matched with a combined structure of an aluminum sleeve cap 1, the top excircle d, the groove bxc and the chamfer d1xa of the aluminum sleeve 2 need to be processed, a numerical control program can be finished by simple trimming, after a spindle blade, a spindle disk and the aluminum sleeve 2 are combined, the detection and the straightening are needed, the center hole is used as a support for finish turning of the appearance and a novel end structure of the aluminum sleeve, the difference from the original production process is that the cutting of the, the spindle rod bending deformation is found even after a period of spinning process until the commodity stage, and the spindle rod coiling combination can be straightened as a reference, so that the service life of the spindle is prolonged. It can be seen that the aluminium sleeve 2 has the distinct advantages: the length of the blank is shortened, and the raw material cost is reduced; the processing flow is reduced and the production efficiency is improved.
