Every other embodiment obtained, fall within the protection scope of the utility model.
The core of the utility model is to provide a kind of sewing machine needle shank, and difficulty of processing is relatively low.
In a kind of specific embodiment of the provided sewing machine needle shank of the utility model, Fig. 2 to Fig. 5 is please referred to, including
Shank ontology 3 and shank collet 6, through-hole has been axially penetrated through in shank ontology 3, and shank collet 6 is equipped with for installing eedle 7
Eedle installing blind 6-5,6 part of shank collet are plugged in the through-hole of shank ontology 3 and fix with 3 phase of shank ontology.
Wherein, which specifically can be used in flat seam machine or other sewing machines.The shank and shank upper bushing 2, needle
The installation relation of the components such as bushing 4, head 1, bottom plate 8 can refer to the prior art under bar.Wherein, eedle 7 can play thorn material
Effect, can not change shank structure thorn cloth feeding principle in the prior art carry out using.
In the present embodiment, since shank collet 6 can be processed with shank ontology 3 in seperated, grafting is then carried out again,
When processing shank, shank ontology 3 can directly be got through along axial direction to form hollow tube, only made a call on shank collet 6 one it is blind
Hole is as eedle installing blind 6-5, easy to process without in the equal processing blind hole in the both ends of shank ontology 3.Meanwhile shank sheet
The hollow setting of body 3, can mitigate the weight of shank, furthermore it is possible to the hollow structure of shank ontology 3 directly be utilized, by needle rod holder
First 6 are directly plugged in shank ontology 3, easy to assembly.
On the basis of the above embodiments, referring to FIG. 3, the shank can also include the folder being arranged in outside shank ontology 3
Collar 5, the clamping ring 5 clamp the plug-in position of needle rod holder head 6 and shank ontology 3.
Due to the setting of clamping ring 5, the assembly precision between shank ontology 3 and shank collet 6, shank ontology can be reduced
Grafting between 3 and shank collet 6 is either interference fitted or clearance fit, can be realized by the clamping of clamping ring 5
Shank ontology 3 is connect with being reliably fixed for shank collet 6.
On the basis of the above embodiments, referring to FIG. 3, clamping ring 5 can specifically include the c-type circle 5-1 of elasticity, installation
When, c-type circle 5-1 can be located in 3 outside of shank ontology by opening, realize clamping action by the elastic force of c-type circle 5-1.
On the basis of the above embodiments, clamping ring 5 can also include being connected to the opening of c-type circle 5-1 to form closing
The connecting pin 5-2 of circle, connecting pin 5-2 are adjustable relative to the position c-type circle 5-1, to adjust the size of sealing ring.
Wherein, connecting pin 5-2 can be specifically connected through a screw thread or other modes are fixedly connected with c-type circle 5-1.
It is adjustable c-type circle 5-1 by adjusting locked position of the connecting pin 5-2 on c-type circle 5-1 in the present embodiment
The size of openings of sizes and sealing ring, and then clamping ring 5 is adjusted to the clamping degree of shank ontology 3, further increase c-type circle
The reliability of 5-1 fastening, can be adapted for the demand of various clamping forces.
Certainly, in other embodiments, clamping ring 5 can also carry out other settings, for example, clamping ring 5 can also be bullet
Spring coil.
Based on any of the above embodiments, the position of grafting needle rod holder head 6 can be set along axial direction on shank ontology 3
The through slot 3-1 of extension.
Specifically, referring to FIG. 4, through slot 3-1 can be set at an axial port of shank ontology 3, i.e., this is logical
The one end of slot 3-1 in the axial direction is hatch frame, easy to process.
In the present embodiment, the diameter change for being set as shank ontology 3 of through slot 3-1 provides certain space, is clamping
When enclosing 5 clamping needle bar body 3, bore of the shank ontology 3 in the position of grafting needle rod holder head 6 can be with relative constriction, i.e. through slot 3-1
Circumferential width accordingly become smaller, it is possible to prevente effectively from clamping ring 5 shank ontology 3 is pressed from both sides it is bad.
Based on any of the above embodiments, shank collet 6 can be greater than the metal clip of shank ontology 3 for heating conduction
Head.
Due in the prior art, at shank and the friction of shank upper bushing under a, shank and shank at bushing friction b and
It is higher that the friction of eedle and c at cloth friction will lead to shank temperature, and temperature is not easy to distribute, and is greater than shank using heating conduction
The metal of ontology 3 makes needle rod holder head 6, can not change original selection at shank ontology 3, can guarantee that shank is basic
While physical property, the radiating efficiency of shank entirety is greatly improved.
Specifically, shank collet 6 is specifically as follows aluminium alloy clamping head.The density of aluminium alloy is 2.7g/cm3, compared to existing
There is shank material 20CrMo in technology easier to process, and can reduce shank weight, to mitigate the inertia of shank reciprocating motion
Power.In addition, the thermal coefficient of aluminium is 237W/mK or so, the capacity of heat transmission of aluminium alloy clamping head is also corresponding preferably, it can be achieved that quickly
It is thermally conductive.
Based on any of the above embodiments, being located on shank collet 6 on the outer peripheral surface except shank ontology 3 can set
Several radiating grooves 6-2 is set, radiating groove 6-2 can be along the axially extending of shank ontology 3.Optionally, radiating groove 6-2 can be arc
Connected in star.
In the present embodiment, the setting of radiating groove 6-2 can increase the heat dissipation area of shank collet 6, meanwhile, radiating groove 6-2
Extending direction it is consistent with the shank direction of motion, using aerodynamic principle, with the axial movement of eedle 7, air-flow can be with
The heat between radiating groove 6-2 is taken away, the heat-sinking capability of shank collet 6 is further increased, protects cloth.
Based on any of the above embodiments, shank collet 6 can specifically include clamper main body 6-3 and be fixed on collet
Mounting blocks 6-1 on the first surface 6-4 of main body 6-3, referring to FIG. 5, mounting blocks 6-1 is inserted from the first port of shank ontology 3
It is connected in shank ontology 3, clamper main body 6-3 is located at except shank ontology 3 and first surface 6-4 offsets with first port.Wherein,
Radiating groove 6-2 is arranged on clamper main body 6-3.
Wherein, first port is one in two ports of through-hole on shank ontology 3, is installed on sewing machine in shank
In after, first port is usually the lower port on shank ontology 3.
In the present embodiment, first surface 6-4 offsets with first port, can play position-limiting action, effectively restriction needle rod holder
First 6 with the inserting depth of shank ontology 3.
Further, first surface 6-4 can close first port with sealing cover, to reduce dust by first surface 6-4
Equal sundries enter inside hollow shank ontology 3.
Each embodiment in this specification is described in a progressive manner, the highlights of each of the examples are with other
The difference of embodiment, the same or similar parts in each embodiment may refer to each other.
