Abstract
The utility model provides an up or down needle stop perpendicular drive industrial sewing motor, which is a bearingless and brushless magnetic suspension motor, comprising a stator assembly, a rotor assembly, a front end cover, a back end cover, an impeller inducer, a needle position sensor, and a coupling bolt. The stator assembly formed by embedded windings is clamped between the front end cover and the back end cover; the back end cover is provided with the needle position sensor inside. A rotor spindle is a hollow tubular bushing which is butted with a principal axis of the industrial sewing machine and is fixedly positioned through screwing up positioning screws to form direct drive. Two permanent magnets matched with the needle position sensor are arranged at proper positions of the impeller inducer, which can achieve accurate up or down needle stop. Pulleys are disused, thereby reducing the abrasion, avoiding pollution of the sewing material and achieving stepless speed regulation within the range from 0 to 6000 r/min; the low noise, reduced vibration, high performance, flexible operation and good safety performance reflect the design concepts of environmental protection and humanization. The industrial sewing motor is widely applicable to be matched with sewing machines for knitting, weaving, luggage, shoes and hat, etc.
Description
Technical field
The utility model relates to the manufacturing technology field of miniature motor, specifically refers to a kind of and the matching used upper and lower needle stop direct-drive type of industrial sewing machine worker seam motor.
Background technology
At present, be used for the drive motors of industrial sewing machine, ac synchronous motor, variable-frequency motor arranged and the permanent magnet AC brushless motor that occurs in recent years etc., but the kind of drive of they and head all is belt transmission usually.This kind of drive no doubt has its superiority, can suitably regulate as belt pulley and the spacing between the head belt pulley and the tightness of belt etc. of motor; Sometimes have only the needlework of three or five pins also can stir belt pulley by hand and carry out work etc.But drive disk assembly is many after all for it, mechanism's relative complex, sometimes also because of the inertia of belt pulley to waste greatly easily cause when some sewing threads and belt clamp cloth stained.At these defectives, the someone proposes the mode with direct driving, and not long ago the applicant had proposed the patent application of a kind of industrial sewing machine with direct drive permanent magnetic alternating-current brushless numerical-control motor, had overcome this problem preferably.The application is the needle clamping mechanism that increases again on this basis the shank of eedle to be lived surely at extreme position up and down, and it is more flexible to make the worker stitch the operation of machine, and the end of a thread is saved more.
The utility model content
The purpose of this utility model is: the deficiency that overcomes the motor driven mode that existing industrial sewing machine uses, replace belt transmission with direct driving, and increased needle clamping mechanism up and down, made the handpiece structure of industrial sewing machine compact more, succinct, more convenient to operate.
The technical scheme of the utility model technical solution problem is: make belt pulley into direct-drive type that machine shaft and head spindle directly link.Described motor is made up of field frame assembly, rotor assembly, front end housing, rear end cap, fan blade, armature spindle, needle-bit sensor, shaft link bolt.Described front end housing, rear end cap connect into open motor housing with trip bolt, between front and rear cover clamping by being embedded the field frame assembly that winding constitutes, in the middle of rear end cap, set up needle-bit sensor, the heat transfer agent line lead-out wire of needle-bit sensor is connected with controller, and being provided with in the middle of field frame assembly can be with respect to its axial rotor rotated assembly.
Described rotor assembly is formed by connecting by the rotor and the armature spindle of permanent magnetic material, described armature spindle is the tubular sleeve of hollow, directly dock with the main shaft that the worker stitches machine head, the fixed cover that links to each other with armature spindle is provided with location hole, make armature spindle and head spindle positioning and fixing with the dog screw screw-in, thereby form direct driving condition.
Described shaft link bolt passes behind the axis hole of fan blade and rear end cap and the armature spindle center to screw with the default internal thread in the outer end of head spindle and is connected, and is fixed with two blocks of permanent magnets that cooperate with transducer in the appropriate location of fan blade.
The utility model industrial sewing machine is the magnetic suspension brushless motor of no bearing with the upper and lower needle stop direct-drive motor.It has not only cancelled belt pulley, realizes no belt transmission, thereby reduces wear, and has avoided the pollution of sewing, also can realize stepless speed regulation in 0～6000r/min scope; Its noise is low, shake little, the usefulness height; Can reach upper and lower needle stop accurately; And when in a single day material causes the running of clamp even load outside having, motor meeting automatic shutdown protection, flexible operation, security performance is good, has embodied environmental protectionization, humanized design concept.Because adopt IC control, voltage is wide, compare with clutch motor, more energy saving during work, power saving rate can reach 87.50%, improves work efficiency 45%.Be widely used in supporting use on the plant equipment such as knitting, braiding, case and bag, shoes and hats, thereby be subjected to users' welcome and favorable comment deeply.
Description of drawings
Fig. 1 is a broken away view of the present utility model;
Each title and mark among the figure: 1. shaft link bolt, 2. screw, 3. fan blade, 4. fan blade, 5. trip bolt, 6. heat transfer agent line, 7. rear end cap, 8. needle-bit sensor, 9. armature spindle, 10. rotor, 11. dog screws, 12. field frame assemblies, 13. attachment screws, 14. front end housings, 15. power supplys and control line, 16. plugs, 17. fixed covers, 18. permanent magnets.
Embodiment
Now with accompanying drawing the utility model is described in further detail in conjunction with the embodiments: as shown in Figure 1, the utility model with front end housing 14, rear end cap 7 usefulness trip bolts 5 connect into open shell, clamping is embedded the field frame assembly 12 that is made of winding between front and rear cover; Being provided with in the middle of field frame assembly 12 can be with respect to field frame assembly 12 axial rotor rotated assembly, and rotor assembly is formed by connecting by rotor 10 and hollow armature spindle 9.Outer end at head spindle is preset with internal thread, and armature spindle 9 is enclosed within outside the head spindle, screws in dog screw 11 in the screw on fixed cover 17, makes armature spindle 9 and head spindle positioning and fixing, thereby forms direct driving condition.Also be fixed with needle-bit sensor 8 on rear end cap 7, its sensor information line 6 leads to outside the casing and with the numerical control speed regulator and is connected.The lead-out wire of field frame assembly 12 windings is connected with plug 16, and plug 16 is inserted in the socket of numerical control speed regulator.With attachment screw 13 front end housing 14 is fixedlyed connected with the head wallboard earlier during installation, then rear end cap 7 usefulness trip bolts 5 are connected and fixed with front end housing 14, field frame assembly 12, rotor assembly are clipped in the middle.And then permanent magnet is tightened on the base plate of fan blade with screw 2; Meanwhile, armature spindle 9 is inserted into head spindle, screw in the default internal thread of head spindle head with shaft link bolt 1, both are fastenedly connected, again dog screw 11 are screwed in fixed cover 17, make armature spindle 9 and head spindle butt joint back positioning and fixing, this product is the electromagnetic levitation type of no bearing, rely on the principle of same-sex repulsion of the magnetic pole between stator and the rotor to make rotating shaft become suspended state, so the frictional force between rotating shaft and the axle sleeve is very little, debugging finishes and can come into operation.When permanent magnet 18 during normal the use when being fixed on fan blade 3 on and needle-bit sensor 8 are in a certain relative position, can make stop on the eedle or under stop.
