Abstract
The utility model is a knitting gauge adjusting device and pertains to the component structure of a sewing machine. The outer side of an adjusting screw rod is fixed with an adjusting button and the inner side contacts the butterfly plate of a knitting gauge base; the shell is provided with a smooth via that matches with a screw barrel; the screw barrel is positioned in the via and the adjusting screw rod coordinates with a screw barrel axis hole thread. The device only needs the smooth via to be processed, thereby reducing the procession difficulty of the shell and improving the shell yield. In addition, the screw barrel is just replaced when the knitting gauge adjusting device wears or is damaged due to thread. Therefore, the utility model is very simple and convenient, without any replacement or discard of the shell thereby avoiding waste effectively.
Description
Technical field:
The utility model relates to the needle gage adjusting device of the parts of Sewing machines, particularly flat seam machine.
Background technology:
Existing flat seam machine needle gage adjusting device, its structure as shown in Figure 1, adjusting screw(rod) 3 penetrates casing 2 and conflicts with needle gage seat 4, adjusting screw(rod) 3 outer ends are with adjusting knob 1.
During the needle gage adjustment device work, mainly be, drive adjusting screw(rod) 3 and in the screw of casing 2, rotate, by the butterfly plate of the top roof pressure needle gage seat 4 of screw rod 3, force needle gage seat 4 to rotate, thereby change the size of needle gage again by rotation adjusting knob 1.Needle gage adjusting power mainly is to be transmitted by the screw thread of attacking at casing 2 screws by adjusting screw(rod) 3 as can be seen, and so just the requirement on machining accuracy to screw on the casing 2 compares higher.In case the screw of casing 2 adds the man-hour precision and does not reach job requirement, will cause whole casing to scrap; The screw long-term work of adjusting screw(rod) 3 and casing 2, the screw of casing 2 occur wearing and tearing easily or damage, and can only change whole casing 2, certainly will cause great waste.
The utility model content:
The purpose of this utility model provides a kind of casing difficulty of processing, swivel nut of reducing and changes needle gage adjusting device convenient and that casing is difficult for scrapping.
Scheme of the present utility model is: the outer end of its adjusting screw(rod) is fixed with adjusting knob, and inner butterfly plate with the needle gage seat contacts, and casing is shaped on the smooth through hole that cooperates with swivel nut, and swivel nut is installed in the through hole, adjusting screw(rod) and swivel nut axis hole threaded engagement.
Swivel nut is the hollow screw shape of smooth outer surface, and its axis hole is shaped on internal thread, the through hole interference fit of bar portion and casing, and cap portion and casing inboard are close to.Be shaped on oilhole between the outside of swivel nut and the axis hole.
The utility model has the advantages that: the casing of said apparatus only need be processed smooth through hole, has reduced the difficulty of processing of casing, and the casing yield rate improves.In addition, when the needle gage adjusting device because of thread abrasion or when damaging, only need to change a swivel nut and get final product, simple and convenient; Do not need to change or scrap casing, thereby avoid waste effectively.
Description of drawings:
Fig. 1 is original flat seam machine needle gage adjusting device structural representation.
Fig. 2 is the utility model structural representation.
The specific embodiment:
With reference to Fig. 2, swivel nut 5 of the present utility model is made of bar portion 5.2 and cap portion 5.3, and the appearance of swivel nut 5 is smooth cylinder, and axis hole is shaped on internal thread.The smooth through hole interference fit of its bar portion 5.2 and casing 2, cap portion 5.3 is close to the inboard of casing 2; Be shaped on oilhole 5.1 between swivel nut 5 outsides and the axis hole.Adjusting screw(rod) 3 and swivel nut 5 axis hole threaded engagement, adjusting screw(rod) 3 outer ends and adjusting knob 1 are fixing, and inner butterfly plate with needle gage seat 4 contacts.
Rotation adjusting knob 1 drives adjusting screw(rod) 3 and rotates in swivel nut 5, owing to tightly conflict in butterfly plate and adjusting screw(rod) 3 the inners of needle gage seat 4, it is bigger that active force is advanced on the right side of adjusting screw(rod) 3, and swivel nut 5 is subjected to reaction force left; The cap portion 5.3 of swivel nut 5 is close to the inboard of casing 2, can prevent that swivel nut 5 from radially sliding left.Opposite spin adjusting knob 1, this moment, adjusting screw(rod) 3 active forces were less, and the power that acts on the swivel nut 5 is also less, and radially sliding to the right can not appear in swivel nut 5.
Lubricating oil in the casing 2 can enter swivel nut 5 axis holes by oilhole 5.1, and the axis hole of the screw thread of adjusting screw(rod) 3 and swivel nut 5 is lubricated for a long time, makes things convenient for adjusting knob 1 rotation.
The casing 2 of said apparatus does not need machining screw, only needs the smooth through hole of processing to get final product, and swivel nut 5 machining screw are fairly simple, reduced the difficulty of processing of casing 2, improve yield rate.In addition, when the needle gage adjusting device because of thread abrasion or when damaging, do not need to change or scrap casing 2, only need to change swivel nut 5 and get final product, easy convenience, thus avoid waste effectively.
