A kind of automatic thread trimming device for air core coil
Technical field
The utility model relates to air core coil field, refers more particularly to a kind of automatic thread trimming device for air core coil.
Background technology
That the tool of automatic thread trimming device is designed to double-deck pattern at present, the start line layer that is clipped in the middle, so cause the cross-line of beginning buttock line of air core coil longer, the beginning buttock line of the air core coil after spiral must carry out secondary operations by staff just can reach the desired size of client, and because air core coil is less, yielding, in operation process, easily cause the beginning buttock line of air core coil to be drawn loose wire and air core coil to deform.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point of the prior art and provides a kind of simple in structure, the practical automatic thread trimming device for air core coil.
The utility model is realized in the following way:
A kind of automatic thread trimming device for air core coil, it is characterized in that: comprise center axis body 1, slip cap 2, line ball pin 3, hanging wire pin 4, tangent line pin 5, tool body 6, described slip cap 2 is connected on center axis body 1, and slip cap 2 with respect to center axis body 1 slidably; Described tool body 6 is connected in the top of center axis body 1; Described tool body 6 is provided with thread managing table 61;
Described line ball pin 3 is connected with slip cap 2 by the first shift fork 7 through tool body 6; Described tangent line pin 5 is connected with slip cap 2 by the second shift fork 8 through tool body 6; Described hanging wire pin 4 is connected on tool body 6; Described line ball pin 3, hanging wire pin 4 and tangent line pin 5 are all positioned at the side of thread managing table 61; Described tangent line pin 5 is between line ball pin 3 and hanging wire pin 4; On described tangent line pin 5, be connected with cutting knife 9.
Preferably, described hanging wire pin 4 is provided with hanging wire groove.
The beneficial effects of the utility model are: simple in structure, the after-treatment of the beginning buttock line that carries out air core coil of reducing a staff, has reduced bad that secondary operation causes, and the dimensional accuracy of air core coil beginning buttock line improves.

The specific embodiment
Now by reference to the accompanying drawings, the utility model specific embodiment is described in detail in detail:
As shown in Figure 1, a kind of automatic thread trimming device for air core coil, comprises center axis body 1, slip cap 2, line ball pin 3, hanging wire pin 4, tangent line pin 5, tool body 6, and slip cap 2 is connected on center axis body 1, and slip cap 2 with respect to center axis body 1 slidably; Tool body 6 is connected in the top of center axis body 1; Tool body 6 is provided with thread managing table 61, as the coiling platform of air core coil 10; Line ball pin 3 is connected with slip cap 2 by the first shift fork 7 through tool body 6, and tangent line pin 5 is connected with slip cap 2 by the second shift fork 8 through tool body 6, and hanging wire pin 4 is connected on tool body 6; Line ball pin 3, hanging wire pin 4 and tangent line pin 5 are all positioned at the side of thread managing table 61, guarantee the start line of air core coil 10 and the size of ending line; Tangent line pin 5 is between line ball pin 3 and hanging wire pin 4; On tangent line pin 5, be connected with cutting knife 9, slip cap 2 motions drive the first shift fork 7 and the second shift fork 8, thereby drive line ball pin 3 to push down start line and the ending line of air core coil 10, and the cutting knife 9 on tangent line pin 5 completes the cutting action of the ending line of air core coil 10 simultaneously.
Line ball pin 3 of the present utility model is provided with wire-hanging hook, for the location of the start line of air core coil 10.
Hanging wire pin 4 of the present utility model is provided with hanging wire groove, for the transition of the ending line of air core coil 10.
When work, the start line of air core coil 10 hangs on line ball pin 3 as start line position, then location is pushed down board entry into service air core coil 10 is wound the line on thread managing table 61, the ending line of the rear air core coil 10 hanging wire groove by hanging wire pin 4 that wound the line draws toward start line position again, then slip cap 2 drives that line ball pin 3 is pushed down, tangent line pin 5 is drop-down, blade 9 on tangent line pin 5 cuts off the ending line of air core coil 10, and air core coil 10 finished products fall, and complete a cycle.Can change the position of line ball pin 4 and the distance of tangent line pin 5 and realize by adjustment the variation of length according to required beginning buttock line length requirement.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model description and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
