A kind of universal middle core of circular knitting machine
Technical field
This utility model relates to field of textile machinery, refers more particularly to the universal middle core of a kind of circular knitting machine.
Background technology
Middle core on circular knitting machine is all a circular knitting machine a middle core, one_to_one corresponding at present;And when the cloth on market or flower pattern need change, it would be desirable to again developing new circular knitting machine solves, and new circular knitting machine must need new middle core to match;Enterprise so can be caused to get the raw materials ready, add production cost, and inefficient, need to put into substantial amounts of man power and material.
Utility model content
The purpose of this utility model is to overcome above-mentioned weak point of the prior art to provide a kind of simple in construction, the universal middle core of practical circular knitting machine.
This utility model realizes in the following way:
A kind of universal middle core of circular knitting machine, it is characterised in that: including that middle core body 1, described middle core body 1 are circular, it uses QT500-7 material to make, and the middle part of described middle core body 1 is provided with installing hole 11;Described middle core body 1 is provided with hole 12, location;The installing plate of described middle core body 1 is provided with first group of installing hole, second group of installing hole, the 3rd group of installing hole.
Described first group of installing hole is to be located in the way of annular array on middle core body 1 by 30 the first installing holes 13;Described first installing hole 13 includes the first screwed hole 131, described first screwed hole 131 be respectively provided on two sides with the first pin-and-hole 132.
Described second group of mounting hole site is in the outside of first group of installing hole;Described second group of installing hole is to be located in the way of annular array on middle core body 1 by 12 the second installing holes 14;Described second installing hole 14 includes screwed hole 141 in second, and in described second, screwed hole 141 is respectively provided on two sides with the second side screwed hole 142;In described second, screwed hole 141 is respectively provided on two sides with pin-and-hole 143 in two second;In described second, pin-and-hole 143 is in second between screwed hole 141 and the second side screwed hole 142;Described second side screwed hole 142 be respectively provided on two sides with the second side pin-and-hole 144.
Described 3rd group of mounting hole site is in the outside of second group of installing hole;Described 3rd group of installing hole is to be located at the 3rd installing hole 15 in the way of annular array on middle core body 1 by 42;Described 3rd installing hole 15 includes the 3rd screwed hole 151, described 3rd screwed hole 151 be respectively provided on two sides with the 3rd pin-and-hole 152.
The installing plate of described middle core body 1 is provided with screwed hole 16.
Described middle core body 1 is provided with bolt hole 17.
The beneficial effects of the utility model are: simple in construction, can install the head of each model circular knitting machine, reduce production cost.

Detailed description of the invention
In conjunction with accompanying drawing in detail, this utility model detailed description of the invention is described in detail:
As shown in Figure 1, Figure 2, Figure 3 shows, the universal middle core of a kind of circular knitting machine, including middle core body 1, described middle core body 1 is circular, and it uses QT500-7 material to make, and the middle part of middle core body 1 is provided with installing hole 11;Middle core body 1 is provided with hole 12, location;The installing plate of middle core body 1 is provided with first group of installing hole, second group of installing hole, the 3rd group of installing hole.
As it is shown on figure 3, first group of installing hole of this utility model is to be located in the way of annular array on middle core body 1 by 30 the first installing holes 13;First installing hole 13 includes the first screwed hole 131, the first screwed hole 131 be respectively provided on two sides with the first pin-and-hole 132.
As it is shown on figure 3, second group of mounting hole site of this utility model is in the outside of first group of installing hole;Second group of installing hole is to be located in the way of annular array on middle core body 1 by 12 the second installing holes 14;Second installing hole 14 includes screwed hole 141 in second, and in second, screwed hole 141 is respectively provided on two sides with the second side screwed hole 142;In second, screwed hole 141 is respectively provided on two sides with pin-and-hole 143 in two second;In second, pin-and-hole 143 is in second between screwed hole 141 and the second side screwed hole 142;Second side screwed hole 142 be respectively provided on two sides with the second side pin-and-hole 144.
As it is shown on figure 3, the 3rd group of mounting hole site of this utility model is in the outside of second group of installing hole;3rd group of installing hole is to be located at the 3rd installing hole 15 in the way of annular array on middle core body 1 by 42;3rd installing hole 15 includes the 3rd screwed hole 151, the 3rd screwed hole 151 be respectively provided on two sides with the 3rd pin-and-hole 152.
In this utility model, the installing plate of core body 1 is provided with screwed hole 16, for the installation of middle core body 1.
In this utility model, core body 1 is provided with bolt hole 17, for the installation of middle core body 1.
This utility model uses first group of installing hole, second group of installing hole, compound mode of the 3rd group of installing hole, can install the head of each model circular knitting machine, greatly reduce production cost, improve the competitiveness of enterprise.
