Abstract
The utility model discloses a main shaft connecting rod mechanism of a high-speed cup seaming machine. The main shaft connecting rod mechanism of the high-speed cup seaming machine comprises a main shaft, a machine needle copper connecting rod, an upper bent needle copper connecting rod, a lower bent needle copper connecting rod and an upper cutter copper connecting rod, wherein the machine needle copper connecting rod, the upper bent needle copper connecting rod, the lower bent needle copper connecting rod and the upper cutter copper connecting rod are sequentially installed on the main shaft, the upper bent needle copper connecting rod is connected with an upper bent needle crank, and the lower bent needle copper connecting rod is connected with a lower bent needle crank. The main shaft connecting rod mechanism of the high-speed cup seaming machine is characterized in that the machine needle copper connecting rod, the upper bent needle copper connecting rod and the lower bent needle copper connecting rod are respectively fixedly provided with an oil shifting piece. The main shaft connecting rod mechanism of the high-speed cup seaming machine is reasonable in structural design, is capable of effectively improving the speed of the sewing machine, lowers noise, reduces the moment, avoids oil leakage of a machine head, and improves the quality of sewn products.
Description
Technical field
The utility model relates to field of mechanical technique, relates in particular to a kind of high speed overlock industrial sewing machine spindle bar-linkage mechanism.
Background technology
In background technology, the mainshaft mechanism of industrial seaming machine is due to the restriction of its material wear ability, part fit tolerance, processing technology, oil supply system, make its speed of making sewing be subject to restriction to a certain extent, and the defect such as moment is heavier, noise is large, head leakage of oil, for overcoming these defects, it is improved.
Utility model content
The purpose of this utility model is in order to make up the deficiency of prior art, and a kind of high speed overlock industrial sewing machine spindle bar-linkage mechanism is provided, and can effectively improve Sewing machines speed, reduces noise, reduces moment, avoids head leakage of oil to improve stitched products quality.
The utility model is achieved through the following technical solutions:
A kind of high speed overlock industrial sewing machine spindle bar-linkage mechanism, include main shaft and be arranged on successively the eedle copper connecting rod on main shaft, upper looper copper connecting rod, lower looper copper connecting rod, upper slitter copper connecting rod, on described upper looper copper connecting rod, be connected with curved needle crank, on described lower looper copper connecting rod, be connected with lower curved needle crank, it is characterized in that: on described eedle copper connecting rod, upper looper copper connecting rod, lower looper copper connecting rod, be also installed with respectively and dial oily sheet.
Described main shaft, upper bending needle ball crank, lower bending needle ball crank adopt 20CrMnTi material, and described eedle copper connecting rod, upper looper copper connecting rod, lower looper copper connecting rod, upper slitter copper connecting rod adopt HB71 material.
Described main shaft is worked in coordination and is connected with eedle copper connecting rod, upper looper copper connecting rod, lower looper copper connecting rod, upper slitter copper connecting rod, upper looper copper connecting rod is in mating connection with upper bending needle ball crank again, lower looper copper connecting rod is worked in coordination and is connected with lower bending needle ball crank again, described main shaft, upper bending needle ball crank, lower bending needle ball crank tolerance employing ± 0.002mm, described eedle copper connecting rod, upper looper copper connecting rod, lower looper copper connecting rod, upper slitter copper connecting rod tolerance employing+0.014/+0.011mm.
The utility model has the advantages that:
1, because spindle bar-linkage mechanism adopts new material, effectively raise toughness, wear resistance, temperature tolerance, thermal diffusivity, the self lubricity of main shaft connecting rod, thereby guaranteed that Sewing machines can be with the speed running of 10000 turn/min.
2,, because spindle bar-linkage mechanism adopts new tolerance fit, main shaft and connecting rod contact surface can be formed with the boundary film of lubrication, and play lubricated, antifriction function.
3, because spindle bar-linkage mechanism does not adopt oil pump forced feed oil system; but adopt the oily sheet that pulls out of spindle bar-linkage mechanism self to get rid of the oil supply system that oil forms mist of oil; both guaranteed spindle bar-linkage mechanism sufficient lubrication; the oil impregnate phenomenon that can effectively prevent again that fuel feeding is excessive and produce, has avoided head leakage of oil, has polluted sewing, has reduced sewing and produce class; And head is without oil pump forced feed oil system, thereby eliminate the noise that oil pump produces when running up, and increased oil pump forced feed oil system and the moment that increases; Thereby also can allow machine move with the rotating speed of 10000 turn/min.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
