The group type is then positioned in the predetermined position of the spindle motor mounting seat 713 by means of the way of the rear seat (such as the arrow L1) by the machine mounting portion 41 of the saddle. The motor assembly end 13 of the spindle 1 is extended into the array of the spindle motor mount 713; then the rear flange mount 50 and the motor stator set 6 are passed over by & As shown by the arrow L2, the spindle motor mount 713 is assembled, and the rear flange mount 50 is combined with the saddle 40 and the rear end of the sleeve 2, and the motor stator set 60 is a state in which the rear flange seat 5〇 and the motor rotor 3〇 are combined (ie, the state shown in FIG. 4); thereby forming a spindle and a motor coaxially arranged, and the main shaft is protruded from the machine The overhanging end can obtain a new type of structural support effect of the double bearing. / / The front flange seat 55 can be provided with a gap 550 (as shown in Figure 2), the lock 5 for the screw can be used to lock the front end of the sleeve 40, thereby making the front end of the sleeve 20 secure; fixed to the saddle i = U XL? spindle motor Same as light configuration module; no women's wear in organic ° (such as grinding machine) _, the rear flange seat 50 sleeve part 6 M380855 51 series includes extension insert, and the method of the flange method In order to use the axis configuration state, this is to make the; and, for the combination of the group, a preset one of the pumping group portion 81 is provided. The 82 of the seat 50 is provided with the blue seat 50 by the bolt module A type. The prefabrication of the sleeve 20 (the extension of the socket insertion sleeve 20 has an axial direction of the stators 85, 86, and is connected to the rear attachment, such as the eighth.) Cooperating with the rear end, 521, the perforated group of the face lock group is not fixed by the pre-flange seat fixing seat 80, and the radial flange of the rear flange is The axial extensions 83, 84 are provided with positions corresponding to 52; in this state, the above-mentioned saddle connection fixing 50 can be 80 between two systems, thereby pre The portion 82 of the flange portion 50 extends into the group to lock the cylinder, and the seat 80 of the seat 40 is temporarily fixed in a half shape to the square knot fixing seat 80 82. Depending on the rear portion 81 and the rear end of the radial sleeve 20 and the 203, 523 spindle motor and the factory module type preset connection, the solid combination positioning unit body will be described by the two sides to the function of the spindle and the cylinder. 】The problem of sharing the same issue is close to its pre-grinding and rear-facing, and it is stable and drooping. It is positioned in the sub-precision group, and the solid state; the uncovering, the innovation of the horse, the inspiration, the life; the other round Set the bearing and the solid support difference to the post-position method, so that the main reason is to use the "spindle motor rotor, unique structural technology to make a move, on the one hand, the end of the sleeve is achieved, due to the positioning effect problem, the seat The group 'and the axis to protect the original creation of the coaxial saddle, type design, because the transmission can be due to the main axis of the pivot group, and the horse can be matched with the main model. Post-method The support of the main shaft of the main shaft is effectively prevented from reaching the stator, and the two sets of shafts can be assembled to allow the main group to be the main group, the main creation, and the motor to stop the pivot group. The fixed end shaft does not need to support the shaft motor to be compared with the motor stator group. [The previous one is a structural system that relies on the loss of the building, and the sleeve is matched with the grinding wheel because the arm is too long. The most accurate and stable configuration of the third installation is 7 M380855. • The vibration error value is greatly reduced, and it can combine the practical progress of better structure and durability with better industrial utilization efficiency. The disclosures of the above embodiments are used to specifically explain the present creation, and although the descriptions are made through specific terms, the scope of patents of the novel creation cannot be limited thereby; those skilled in the art can understand the spirit of the creation.
