INSTRUCTIONS: [Technical field to which the invention pertains] In particular, a direct-drive industrial sewing machine The present invention relates to a sewing machine. [Prior Art] According to the general sewing machine, it can be divided into household and industrial sewing machines with emphasis on output efficiency. Industrial® double-month b and durability, so it has twin characteristics: and good heat-resistant temperature are all work: Most of them are arranged in a large number of installations in the factory, and the number of operators are sewing. Therefore, if the supply is more active, the noise value generated by the machine is simultaneous. In the environment of the value of the sang, it is not only easy. Production: 2: The phase is 'during long-term low production efficiency; based on the above, the invention is improved. The combination of the main machine and the motor is not the case, as shown in the first figure, the basin and, The motor 2°...fixed frame-, two: two? 10a includes a base 11a and a connection β 13⁄4 . 4 2 (1 f 12a, inside the upper f 12a is worn inside and called an inner cover: the outer frame cover 21a, - accommodating in the outer frame cover 21 ... two =:; 3: wearing: the rotor is fixed to the inside of the outer frame cover 21a corresponding to the rotor and the motor a2 (the stator 24a placed in the T; the fixed frame is attached to the Between the station and the crying river &, the connection between the body i〇a and the motor 2〇& a is used to achieve the spindle 13a and the drive shaft 2 such as the head of the 200909634 connection; thus, to constitute the sewing, however, the conventional seam machine and the structure. There are still the following problems: Actually, the use of Pazhou a is connected to the body i〇a, which is such that the motor 2 is exposed to the outside of the body, and the motor 20a is exposed to the body 10a at 2〇a, and the motor 20a and the body sun are high. The noise value; the volume is large and the length is long and the way is connected, so that the whole package is packaged, so that the package: the dragon and the carton are low, and in the process of the ship, the ',, and the method are effectively obtained. Cost, · Moreover, the main shaft 13a is connected to the transport and transport, often due to the fixed holes: = you improve with the coupling. The difficulty and inconvenience of the field; the actual needs [invention]鏠 机 , , , , , , , , , , , , , , , , , , , , , 隐藏 种 宜 宜 宜 具有 具有 具有 具有 具有 具有 具有 具有 具有 具有 具有 具有 具有 具有 具有 具有 具有 具有 具有 具有 具有 具有 具有 具有 具有 具有 具有 具有 具有 具有 具有 具有 具有 具有 具有In the arm = the body contains a base and - connection Base=;: The main groove of the gutter has a receiving groove and has a receiving portion, and the structural system is accommodated in the upper arm of the machine body of the slit 35 and is disposed at the main axis and the main axis of the sea: Rotating rotor, the inner chamber of the valley and corresponding to the stator of the rotor configuration. 200909634 Another purpose of this month is to provide an industrial 鏠 initial machine, which is driven by Hanzi μ #, 臧 motor On the body, m H" is fixed to the main shaft and the machine to overcome the machining error of each component and improve the assembly. Doors, and clothes are too private = inventions - the purpose is to provide - hidden Motor, seam rushing machine, which is based on the volume of the body assembly structure by the motor in the seam rush machine, and then reduces the packaging material. [Implementation] The detailed description and the technical description of the present invention are provided, but the drawings are only provided to limit the scope of the temple and the description. Please refer to the second and third figures, which are respectively a perspective exploded view and a combined partial cross-sectional view of the present invention. The present invention provides an industrial sewing machine with a hidden motor, which mainly includes a sewing machine body 1G and - motor 2〇, wherein: the sewing machine body 10 comprises a base 11, an upper arm 12 connected to the base u, and a cover 13 covering the top surface of the upper arm 12, the base and the upper arm = most of the Casting in cast iron, and the cover plate can be die-casted for the name material. After the upper arm 12, a receiving groove 14 is formed inside and a spindle 15 is formed through the receiving groove 14. The spindle 15 is made of a bearing. 16 is fixedly connected to the upper 2; in the bottom (4) and the upper part 2, there are components or devices such as linkage mechanism, transmission mechanism, needle reversal, needle bar, etc., and the aforementioned components and devices are conventional technologies. Therefore, the motor structure 20 is accommodated inside the arm i2 of the above-mentioned sewing machine body 1 , and includes a rotor 21 and a sub- 22 '. The rotor 21 is made of a magnetic material such as a permanent magnet. And formed N on it, "Holy, The rotor 21 of the present embodiment is sleeved on the spindle 15 and rotates therewith; the other stator 22 is surrounded by a plurality of coil sets, and is disposed inside the receiving sample 14 and disposed corresponding to the rotor 21. In addition, the motor structure 2G further includes an insulating sleeve 23 which is interposed between the accommodating groove 14 and the stator 22, thereby isolating the influence of the upper arm 12 made of metal on the stator 22, and the rotor 21 and the stator & are released. 3 'In order to prevent foreign matter or oil and gas from entering the inside of the insulating sleeve 23, an oil seal 24 may be disposed on the inner side of the stator 22 of the insulating sleeve 23; X, the other end of the insulating sleeve 23 away from the oil seal 24 is sleeved with another shaft (four) and - The sleeve 26 is sandwiched between the insulating sleeve 23 and the bearing 25 to prevent bending deformation of the end of the spindle 15 due to insufficient rigidity. ', and δ日守 first combines the main shaft 15 and the bearing 16 6 , and then penetrates into the upper arm 12 , and the bearing 16 is tightly fixed in the hole in front of the accommodating groove 14 , the oil seal 24 and the sleeve of the stator 22 26 is respectively inserted into the insulating sleeve 23, and then placed in the receiving groove 14 of the upper arm 12; then, the rotor 21 is sleeved on the main shaft 15, and pushed into the insulating sleeve 23, so that the rotor 21 corresponds to the stator 22, the rotor 21 is further shackled and connected; finally, the bearing 25 is sleeved on the main shaft 15 and pushed into the sleeve 26 in the direction of the main shaft 15; in use, the excitation interaction between the rotor 21 and the stator 22 is utilized. Acting, the rotor 21 and the spindle cymbal 5 can be driven to rotate relative to the sub-22. Knowing that the 'industrial seam 200909634 with hidden motor of the present invention has industrial applicability, novelty and advancement, and the structure of the present invention has not been seen in the same product.
