Abstract

Aimed is to achieve both of stabilization of a sewing mechanism and simplification of a resin machine frame in a sewing machine where the sewing mechanism is arranged in the resin machine frame. The sewing machine is provided with: the resin machine frame where a base part, a leg pole part erected from one end part of the base part and an arm part extended over the base part from the leg pole part are molded integrally; and the sewing mechanism arranged in a space from the base to the arm part through the leg pole part so as to carry out a sewing function as a whole. The sewing mechanism is supported in the machine frame by a frame body consisting of a press-worked base frame corresponding to the base part; a press-worked leg pole frame assembled to one end part of the base frame so as to correspond to the leg pole part; and a press-worked arm frame assembled to the leg pole part so as to correspond to the arm part.

Description

Sewing machines

Technical field

The present invention relates to a kind of Sewing machines, particularly relate to the internal structure of the frame of Sewing machines.

Background technology

As everyone knows, be provided with sewing mechanism in the frame of Sewing machines, this sewing mechanism is supported by the resin system frame of for example enhancing shown in the patent documentation 1.

Patent documentation 1: the spy opens the 2003-169989 communique.

Really, because sewing mechanism is supported by the resin system frame that strengthens, when Sewing machines was worked, even the sewing mechanism appearance is vibrated, it is stable that frame also can keep, thus the problem that can avoid needle downing position for example to change.

But, strengthen anti-shaking (gaining in strength) in order to make resin system frame, in the inside of resin system frame many ribs must be set.Like this, the moulding of resin system frame just becomes complicated.Also have, owing in resin system frame sewing mechanism is set, rib must be configured to and can not interfere with sewing mechanism, therefore is difficult to the intensity that obtains stipulating sometimes.

Summary of the invention

So problem of the present invention is to provide the Sewing machines that the problems referred to above can not occur.

For the technological means of the technical scheme 1 that solves above-mentioned problem for constituting,

" as having; erect the socle portion that is provided with and the resin system frame of the arm integral forming that extends to the top of above-mentioned pedestal part from above-mentioned socle portion; and integral body has the sewing function and is configured in from the Sewing machines of above-mentioned pedestal part via the sewing mechanism of above-mentioned socle portion in the space of above-mentioned arm; it is characterized in that; the bedframe of the punch process corresponding; the socle framework of the punch process on the end that is installed in above-mentioned bedframe corresponding with above-mentioned socle portion with above-mentioned pedestal part from an end of above-mentioned pedestal part by pedestal part, corresponding with the above-mentioned arm arm framework that is installed in the punch process on the above-mentioned socle framework is formed frame body, supports above-mentioned sewing mechanism in above-mentioned frame " Sewing machines.

As optimal way, the Sewing machines of said structure is shown in technical scheme 2, and a side and the opposite side of arm framework link together by the beam parts.

According to technical scheme 1 described Sewing machines, sewing mechanism is supported by the framework that 3 split-frame by punch process assemble, so resin system frame is to shake mechanism and freely constitute with respect to sewing mechanism anti-, therefore can simplified structure.

The specific embodiment

Followingly implement best mode of the present invention with reference to description of drawings.

Among Fig. 1 and Fig. 2, Sewing machines 10 has resin system frame 20.Resin system frame 20 is by the pedestal part 21 that is placed on the operating desk (not shown), erect the socle portion 22 that is provided with and arm 23 integral formings that extend to the top of pedestal part 21 from this socle portion 22 forms from an end of above-mentioned pedestal part 21.

The single space that the state that the inner space 25 of resin system frame 20 is communicated with for the inner space 28 by the inner space 27 of the inner space 26 of pedestal part 21, socle portion 22, arm 23 forms.

Among Fig. 1 and Fig. 2, the inner space 25 of resin system frame 20 is drawn as open state, and this open surface becomes it and is closed by the cover (not shown).

As described later, contain 30 that supported by Fig. 1, Fig. 3 and framework shown in Figure 4, as to play sewing effect sewing mechanism 40 in the inner space 25 of resin system frame 20.3 frameworks that framework 30 forms for punching press iron plate (bedframe 31, socle framework 32 and arm framework 33) assemble, owing to be firm structure, can make sewing mechanism 40 avoid vibration effect.But the bedframe 31 of framework 30, socle framework 32 and arm framework 33 are housed in respectively in the inner space 28 of inner space 27, arm 23 of inner space 26, the socle portion 22 of pedestal part 21.Also have, arm framework 33 is installed on the socle framework 32 as single strutbeam, be asymmetrical shape under the situation of overlooking, and there is step in above-below direction, therefore strengthen purpose (in order to prevent the perk distortion) in order to reach, the downside of the upside of leading section and base end part (socle framework 32 sides) links together by beam parts 34.

Above-mentioned 3 frameworks, promptly bedframe 31, socle framework 32 and arm framework 33 carry out assembling the time, on the installation portion of adjacent framework, have and overlap the hole, utilize the bolt (not shown) that 2 holes are linked together.This point is a well known fact, and the Therefore, omited describes in detail.But in this syndeton because in (between socle framework 32 and the arm framework 33) non-existent space of perk part between bedframe 31 and the socle framework 32, so framework 30 has very high twisting rigidity.

In addition, this connection can also be adopted welding, riveted joint or mode such as chimeric certainly except above-mentioned bolt.

As everyone knows, sewing mechanism 40 is that mechanism, lower shaft are that mechanism and style produce mechanism and form by last axle, and last axle is that mechanism, lower shaft are the blocking and to form spool be that unit 41, lower shaft are unit 42 and style generation unit 43 respectively again of mechanism and style generation mechanism.As Fig. 5-shown in Figure 7, last axle is that unit 41 is configured to be supported in the arm framework 33.In addition, as Fig. 8-shown in Figure 10, lower shaft is that unit 42 is configured to be supported in the bedframe 31, and as Figure 11-shown in Figure 13, style generation unit 43 is configured to be supported in the socle seat framework 32.

Also have, when changing specification, when for example change going up axle and be mechanism/lower shaft and be mechanism/style and producing mechanism, by being that unit/style generation unit/lower shaft is that other arm framework (not shown)/other socle framework (not shown)/other bedframe (not shown) of unit just exchanges and can realize purpose simply with the axle of going up that other are installed with arm framework 33/ socle framework 32/ bedframe 31.
