Description

Technical Field

[0001] The invention relates to the field of textile technology, in particular to a needle cylinder forming device for optimizing the core component of a knitting circular machine. Background Art

[0002] The circular knitting machine is an instrument used in the field of textile science and technology. The main function of the needle cylinder is to fix the knitting needles of the circular knitting machine and drive the knitting needles to work. According to the number of holes on the side wall of the inner circle of the needle cylinder, the needle cylinder is divided into different numbers of needles. The holes in the inner circle of the needle cylinder are formed by drilling with a drill bit.

[0003] Through searching, Chinese patent announcement number CN218946407U discloses a needle cylinder forming device for a large circular knitting machine, comprising: a machine base, a clamping plate, a needle cylinder processing part is clamped between the clamping plates, the upper end of the machine base is connected with a connecting plate through a first electric push rod, the lower end surface of the connecting plate is fitted with a fixed panel, the fixed panel is connected with a fixed block through a sliding rod, a mounting plate body is welded at the lower end of the fixed block, a drill bit is screwed to the side end of the mounting plate body through a connecting piece, a second motor is fixed to the upper end of the drill bit, the second motor and the side end of the connecting piece are both connected with a transmission shaft, and the transmission shaft is connected with a transmission belt through a transmission wheel; With respect to the above-mentioned related technologies, the inventor believes that there are the following defects: 1. In the prior art, holes are directly punched by a drill bit. Since the blank ring is subjected to the extrusion force of the punching, it is difficult to ensure that the shape of the syringe will not be deformed during the processing. In order to ensure the high efficiency of the drilling, high-frequency contact extrusion is required for close drilling, but the existing punching equipment does not have this effect.

[0004] 2. The edge of the needle cylinder is relatively rough after punching, which affects the movement of the knitting needle, and the conventional grinding device cannot grind the holes on the arc surface, so it is impossible to grind the burrs inside and outside the holes.

[0005] 3. Conventional grinding devices are not convenient for grinding circular holes of different diameters while ensuring roundness. Therefore, when grinding holes on the surface of the syringe, it is not applicable to holes of different diameters. Summary of the invention

The lower end of the lifting shell 6 is a circular ring 61. A lifting telescopic rod 62 is fixedly connected to the surface of the circular ring 61 at the lower end of the lifting shell 6.

The floating rod 92 is elastically pushed by the extrusion ring 82, so that the floating rod 92 will not directly squeeze the workpiece when pushing the hole-opening drill bit 10, thereby preventing the workpiece from being deformed.

[0031] The free end of the electric telescopic rod 11 is fixedly connected to a wrapping shell 12, and a central axis 13 is fixedly connected to the inner side of the wrapping shell 12. An electric extension rod 14 is rotatably connected to the surface of the central axis 13.
