Abstract
The utility model relates to a needle replacing device of a needle plate. The device comprises a template, a fixed groove formed in the center of the template and used for holding a bottom plate of the needle plate, and electric heating wires arranged in the fixed groove. When the device is used, the bottom plate of the needle plate which requires to replace needles is put into the fixed groove of the template, and the electric heating wires are electrified to heat the bottom plate of the needle plate; after the bottom plate reaches a certain temperature, mounting holes in the bottom plate of the needle plate are enlarged, and the needles can be replaced; the electric heating wires are cut off power; and after the needles are cooled, the needles are tightly matched with the mounting holes in the bottom plate of the needle plate and fixed firmly. The needle plate made through the device and the method is good in quality and long in service life, is fixed firmly, and can reduce halt of equipment and improve the production efficiency. The device has the characteristics of convenience in needle replacement of the needle plate and high reliability.
Description
Technical field
The utility model relates to equipment such as a kind of needing machine and changes the equipment of pin with needle plate, specifically is a kind of needle plate needle changing device.
Background technology
Easily worn part in the needle plate needing machine needs regularly the pin bar on the needle plate to be changed.Lack the method for the pin bar fixation be suitable for making replacing in the prior art, pin bar difficulty is big, promptly is to change pin firmly, fragile pin bar.
Therefore, how solving the replacing problem of needle plate pin bar, is the technical problem that this area will solve.
The utility model content
The technical problem that the utility model will solve provide a kind of simple in structure, needle plate change pin convenient, change fixation of pin bar and the higher needle plate needle changing device of reliability behind the pin.
In order to solve the problems of the technologies described above, the utility model provides a kind of needle plate needle changing device, comprising: template, the holddown groove of being located at this base plate of placing needle plate in central being used for of template and the electrical heating wire of being located at this holddown groove.
The technique scheme of the utility model is compared prior art and is had the following advantages: the needle plate needle changing device of the utility model; During use; The base plate that need are changed the needle plate of pin bar places the holddown groove of template, the base plate of electrical heating wire energising heating needle plate, reach certain temperature after; It is big that installing hole on the base plate of needle plate becomes, and can change the pin bar this moment.Stop then electrical heating wire is switched on; After cooling, the pin bar tightly fits in the installing hole on the needle plate base plate and fixation.The needle plate quality of working it out through this apparatus and method is good, fixation, and the needle plate long service life can reduce equipment booth platform, enhances productivity.Have needle plate and change the convenient and higher characteristics of reliability of pin.
Description of drawings
For the content that makes the utility model is more clearly understood, below basis specific embodiment and combine accompanying drawing, the utility model is done further detailed explanation, wherein
Fig. 1 is the contour structures sketch map of the needle plate needle changing device among the embodiment;
Fig. 2 is the vertical view of needle plate;
Fig. 3 is that the A of the needle plate among Fig. 2 is to view.
The specific embodiment
See Fig. 1-3, the needle plate needle changing device of present embodiment comprises: template 1, the holddown groove 2 of being located at this base plate of placing needle plate 4 in template 1 central being used for and the electrical heating wire 3 of being located at this holddown groove 2.
During use, the base plate that need are changed the needle plate 4 of pin bar places the holddown groove 2 of template 1, the base plate of electrical heating wire 3 energising heating needle plates 4, reach certain temperature after, it is big that the installing hole on the base plate of needle plate 4 becomes, can change pin bar 5 this moment.Stop then electrical heating wire 3 energisings; After cooling, pin bar 5 tightly fits in the installing hole on needle plate 4 base plates and fixation.
Obviously, the foregoing description only be for explain clearly that the utility model does for example, and be not to be qualification to the embodiment of the utility model.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation or change.Here need not also can't give exhaustive to all embodiments.And conspicuous variation that these spirit that belong to the utility model are extended out or change still are among the protection domain of the utility model.
