Detailed description of the invention
First object of the present utility model is to provide a kind of presser feet adjusting device, when the structural design of this presser feet adjusting device can solve rotation mandrel 1 effectively, electromagnetic core follows the problem of rotation, and second object of the present utility model is to provide a kind of Sewing machines comprising above-mentioned presser feet adjusting device.
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 2-Fig. 4, the presser feet adjusting device that the utility model embodiment provides comprises electromagnet, electromagnetic core 2, mandrel 1, core print seat, drive link, driving driving lever, holder 5, compression elastic piece and preload piece.Same as the prior art, electromagnetic core 2 and mandrel 1 are all positioned at electromagnet inside, and core print seat is fixed on one end of electromagnet, and drive link is connected with driving driving lever.Mandrel 1 has first end and the second end, and wherein the first end of mandrel 1 exposes to electromagnet through core print seat, and mandrel 1 and core print seat are slidably matched.Mandrel 1 is fixedly connected with by screw thread with electromagnetic core 2, and mandrel 1 and electromagnetic core 2 are coaxially arranged.So when mandrel 1 rotates in screwed hole, mandrel 1 entirety moving axially along screwed hole, realizes with this height that adjustment presser feet lifts.Drive the connected one end of drive link to move when mandrel 1 moves, the other end of drive link is connected with driving driving lever, and the support bar of presser feet is connected to realize linking with driving driving lever.Focus on, the outer wall of electromagnetic core 2 offers chute, and the length of chute extends along the direction being parallel to electromagnetic core 2 axis, namely chute is parallel to the axis of electromagnetic core 2.Holder 5 is fixed on the outside of electromagnetic core 2, and holder 5 offers storage tank, and the notch opening of storage tank and bottom land are closed.Compression elastic piece is arranged in holding tank, one end of compression elastic piece and the bottom land of holding tank offset, the other end of compression elastic piece is fixedly connected with preload piece, and the length of compression elastic piece is arranged along the radial direction of electromagnetic core 2, namely the contraction of compression elastic piece and draw direction are along the radial direction of electromagnetic core 2.The depth direction of holding tank is also along the radial direction of electromagnetic core 2.Preload piece to be fastened in chute and to offset with the inwall of chute, namely preload piece is positioned at chute, and preload piece can with the inwall relative movement of chute.
During the presser feet adjusting device that application the utility model embodiment provides, when carrying out the height regulating presser feet to lift, mandrel 1 can be driven to rotate, when mandrel 1 rotates, it can overall moving axially along mandrel 1 and electromagnetic core 2.Because one end of compression elastic piece and the bottom land of the holding tank other end that offsets is fixed with preload piece, and the chute inwall of preload piece and electromagnetic core 2 offsets, and the length of compression elastic piece is arranged along the radial direction of electromagnetic core 2, preload piece like this is fastened in the chute of electromagnetic core 2, and preload piece only can slide along the length direction of chute and namely slide along the direction being parallel to electromagnetic core 2 axis, preload piece can stop that the sidewall of chute rotates, and then achieve and stop electromagnetic core 2 to rotate along with mandrel 1, avoid electromagnetic core 2 rotation and cause the excessive height that setting stroke changes and presser feet lifts of presser feet or too low situation.
In addition, when the solenoid is energized, electromagnetic core 2 because magneticaction band moving mandrel 1 is to moving until electromagnetic core 2 and core print seat offset near the direction of core print seat, the inwall relative sliding of preload piece and chute.When electromagnet power-off, electromagnetic core 2 can move to the direction away from core print seat due to the effect of the Action of Gravity Field of presser feet or return unit, finally resets.In order to reduce the frictional force between preload piece and the inwall of chute, wherein preload piece can be specially steel ball 4, and steel ball 4 is point cantact with the inwall of chute, and contact area is less and frictional force is less.Certainly, preload piece can also be cuboid part etc., in this no limit.
Further, the inwall of chute can be arcwall face, and the figure that namely inwall of chute obtains after the face cutting perpendicular to electromagnetic core 2 axis is camber line.Ensure that the contact of chute and steel ball 4 is for point cantact with this.Certainly, the inwall of chute can also be U-shaped, and namely the cross section of chute is square.
Compression elastic piece can be Compress Spring 7, and namely one end of Compress Spring 7 and the bottom land of the holding tank other end that offsets is fixedly connected with preload piece, and namely the length of Compress Spring 7 axially arranged along the axis of electromagnetic core 2.Certainly, compression elastic piece can also be latch plate etc., in this no limit.
In addition, holder 5 can offer through hole, one end of through hole forms holding tank by after the first screw 6 shutoff of being threaded with hole wall.Namely the bottom land of holding tank is the first screw 6 be threaded with cell wall.So can by the dismounting and change compression elastic piece of the first screw 6, it is more convenient to safeguard.
For the ease of the dismounting of holder 5, holder 5 can be fixed on the end cap 3 of this presser feet adjusting device by the second screw.Certainly, the support supporting holder 5 also can be set separately, in this no limit.
Misplace when offseting to prevent electromagnetic core 2 and core print seat, core print seat can have can the groove of accommodating electromagnetic core 2 end, and the end of electromagnetic core 2 is taper.Wherein, the end face of electromagnetic core 2 is plane, and the end of electromagnetic core 2 is conical local, and electromagnetic core 2 like this moves its end and directly falls in the groove of core print seat.
Based on the presser feet adjusting device provided in above-described embodiment, the utility model additionally provides a kind of Sewing machines, and this Sewing machines comprises any one presser feet adjusting device in above-described embodiment.The presser feet adjusting device in above-described embodiment is have employed, so the beneficial effect of this Sewing machines please refer to above-described embodiment due to this Sewing machines.
In this description, each embodiment adopts the mode of going forward one by one to describe, and what each embodiment stressed is the difference with other embodiments, between each embodiment identical similar portion mutually see.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the utility model.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein when not departing from spirit or scope of the present utility model, can realize in other embodiments.Therefore, the utility model can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
