Description
Technical Field
The utility model belongs to the field of accessories of weft knitting machines, and particularly relates to an improved lower needle cylinder applied to an intelligent numerical control middle circular knitting machine.
Background
The middle circular knitting machine belongs to a middle weft knitting machine, is mainly used for processing complete thermal underwear, and a lower needle cylinder in the traditional middle circular knitting machine is formed by splicing an upper cylinder body and a lower cylinder body and then fastening and connecting the upper cylinder body and the lower cylinder body through locking bolts.
In addition, the upper and lower cylinders need to accurately align the bolt holes on the bottom surface of the upper cylinder and the bolt holes on the top surface of the lower cylinder when in splicing and assembling, so that the problems of time and labor waste are caused when workers splice and assemble the upper and lower cylinders.
Disclosure of Invention
In order to solve the problems, the utility model provides an improved lower needle cylinder applied to an intelligent numerical control middle circular knitting machine, which has the characteristics of more convenient and faster splicing and installation and stronger splicing.
In order to achieve the above purpose, the utility model is realized by the following technical scheme: an improved lower needle cylinder applied to an intelligent numerical control middle circular knitting machine comprises an upper section cylinder body and a lower section cylinder body, and is characterized in that,
the outer diameter side of the bottom surface of the upper section cylinder body is milled with a circle of buckling ring protruding downwards through a milling machine;
the outer diameter side of the top surface of the lower section cylinder body is milled with a circle of downward concave buckling grooves by a milling machine;
the buckling ring on the bottom surface of the upper section cylinder body can be buckled with the buckling groove on the top surface of the lower section cylinder body downwards;
2-20 vertical first bolt holes are formed in the inner diameter side of the bottom surface of the upper section cylinder body in an upward milling mode through a milling machine, and 2-20 first positioning holes are formed in the lower end of the inner diameter surface of the upper section cylinder body in a drilling mode;
the number of the first positioning holes is the same as that of the first vertical bolt holes, the first positioning holes correspond to the first vertical bolt holes one by one, and each first positioning hole can be screwed into one L-shaped positioning rod;
2-20 vertical bolt holes II are milled downwards on the inner diameter side of the top surface of the lower section cylinder body through a milling machine, and 2-20 positioning holes II are drilled at the upper end of the inner diameter surface of the lower section cylinder body;
the number of the second positioning holes is the same as that of the second vertical bolt holes, the second positioning holes correspond to the second vertical bolt holes one by one, and each second positioning hole can be screwed into one L-shaped positioning rod II;
the number of the second vertical bolt holes is the same as that of the first vertical bolt holes, and after the first L-shaped positioning rods are vertically aligned with the second L-shaped positioning rods, the first vertical bolt holes can be relatively aligned with the first vertical bolt holes and screwed into a locking bolt;
the upper section cylinder body is fastened above the lower section cylinder body through the locking bolt.
The buckling ring and the buckling groove are embedded, so that the contact surface area of the upper section cylinder body and the lower section cylinder body can be increased, and the buckling ring can tightly clamp the lower section cylinder body, thereby effectively preventing dislocation of the lower section cylinder body and the upper section cylinder body in the running process.
After the L-shaped positioning rod I is aligned with the L-shaped positioning rod II, the vertical bolt hole I can be aligned with the vertical bolt hole II rapidly and accurately, so that the assembly worker can install the assembly machine in a time-saving and labor-saving manner.
The utility model has the advantages of more convenient and fast splicing and installation and more firm splicing.
The utility model is described in further detail below with reference to the accompanying drawings.
