Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-5, the present invention provides a technical solution: the nut sleeve comprises a nut sleeve body 1, a first bolt 22 and a second bolt 41, wherein the nut sleeve body 1 comprises a flange section 2, an intermediate section 3 and a non-flange section 4, the flange section 2 and the intermediate section 3 are fixedly connected through the first bolts 22, the intermediate section 3 and the non-flange section 4 are fixedly connected through the second bolts 41, a plurality of thread channels 5 are formed in the inner walls of the flange section 2, the intermediate section 3 and the non-flange section 4, in the first embodiment, the large-lead nut sleeve body 1 can be fixedly connected in a two-part mode, namely, the flange section 2 and the non-flange section 4 are fixedly connected together through the first bolts 22 with even intervals, in the second embodiment, the first large-lead nut sleeve body 1 can be fixedly connected in a three-part mode, and when the first lead is divided into three, the flange section 2 and the non-flange section 4 are fixedly connected to the intermediate section 3 through the first bolts 22 and the second bolts 41 respectively The sections need to be precisely assembled, so that the steel ball is ensured to be smooth and stable when rolling and advancing in the thread groove, the problem that the existing internal thread grinding machine is difficult to process a large-lead nut is solved, one side of the flange section 2 is fixedly connected with a flange 21, the flange section 2 and the flange 21 are in an integrally cast structure, the number of the first bolts 22 is six, six first bolts 22 are uniformly distributed, the number of the second bolts 41 is six, and the six second bolts 41 are uniformly distributed, six first threaded holes are uniformly arranged at corresponding positions of the flange section 2 and the middle section 3 at intervals, and the first bolt 22 is in threaded connection with the first threaded hole, a plurality of second threaded holes are uniformly arranged at corresponding positions of the middle section 3 and the non-flange section 4 at intervals, and the second bolt 41 is in threaded connection with the second bolt holes.
The working principle is as follows: when the large-lead nut sleeve is used, the large-lead nut sleeve body 1 can be fixedly connected in a mode of being divided into two parts, namely the flange section 2 and the illegal flange section 4 are fixedly connected together through six first bolts 22 with uniform intervals, the large-lead nut sleeve body 1 can also be fixedly connected in a mode of being divided into three parts in the second embodiment, when the flange section 2 and the non-flange section 4 are respectively and fixedly connected to the middle section 3 through the first bolts 22 and the second bolts 41, precise assembly is needed among the sections, smooth and stable when a steel ball rolls and advances in a thread channel is guaranteed, and the problem that the large-lead nut is difficult to process by an existing internal thread grinding machine is solved.
