[Prior Art] Rotating machines such as motors and motors are the most common power sources for machinery. With the improvement of machining precision, the requirements for angular positioning and angular velocity constant speed of rotating machines are relatively improved. While the angle encoder senses the angle and calculates the angular velocity as the most widely used and cost-effective measurement scheme, the angle encoder measurement angle sensing method is optical and magnetic. For the purpose of good sensing, whether optical optical discs and optical sensors or magnetic magnets and magnetic sensors, the basic requirements for mounting the above-mentioned sensing element on the rotating shaft of a power rotating machine For, you must focus on the heart and specify the spacing.

The device assembly 2〇〇 includes a sleeve 104, 204 'The sleeve is mounted with a disc 1〇2 or a magnet 202 knot 201204945, and the sleeve is sleeved around the shaft (not shown) and then stopped (SETUP) ) Screw i 〇6, lock the rotating shaft. Although the sensor installation method can achieve a good axial positioning, but because the stop screw will push the shaft to one side, and the eccentricity results, the tolerance between the shaft and the sleeve needs to be accurate, so most sleeves It is made of metal materials, regardless of material or quality, and the manufacturing method requires high cost of lathe processing.
為節省材料及加工成本，另一習知的磁性編碼 器標誌固定裝置總成300,如第3圖所示，包括有一 標誌7L件如磁石302，與塑膠套筒3〇4結合，套筒3〇4 具有一裂口 306以增加彈性，一扣環溝槽3〇8，以套 筒304夾住轉軸並固定於轉軸（圖未示）上，再以c型 金屬扣環310扣於扣環溝槽3〇8輔助夾持。這種方法 雖然可行，但由於内部轉軸（圖未示）以及外部c型扣 環310都是剛性遠較塑膠套筒3〇4高的金屬製品，因 夾持產生之彈性變型完全由塑膠套筒壁的材料吸收 其應變大承受應力也大，所以加快扣環溝槽3 處的潛變及老化的速度，裝置壽命因此受限，且因 為套筒壁在組裝時應變應力大，組裝上也較困難。 因此’習知將角度感測標該元件安裝固定於旋 轉機器轉軸上的方法及裝置，有如上之缺點以待克 201204945In order to save materials and processing costs, another conventional magnetic encoder sign fixing device assembly 300, as shown in FIG. 3, includes a mark 7L member such as a magnet 302, which is combined with a plastic sleeve 3〇4, and a sleeve 3 〇4 has a slit 306 to increase the elasticity, a buckle groove 3〇8, the sleeve 304 is clamped to the rotating shaft and fixed on the rotating shaft (not shown), and then the c-shaped metal buckle 310 is fastened to the buckle groove. The slot 3〇8 assists in clamping. Although this method is feasible, since the internal shaft (not shown) and the outer c-type buckle 310 are metal products that are much stiffer than the plastic sleeve 3〇4, the elastic deformation due to the clamping is completely made of the plastic sleeve. The material of the wall absorbs the strain and the bearing stress is also large, so the creeping and aging speed of the buckle groove 3 is accelerated, the service life of the device is limited, and because the strain of the sleeve wall is large during assembly, the assembly is also relatively high. difficult. Therefore, the method and device for mounting the element on the rotating shaft of the rotating machine are known to have the above disadvantages.

According to the invention, 'the hollow sleeve, 1 for the component to be applied', such as an optical or magnetic encoder sensing element, the other end has a plurality of parallel slits, and the hollow sleeve is provided with a split end, The outer spiral groove 'and the spring for screwing into the outer spiral groove of the hollow sleeve, and then the hollow sleeve is sleeved with one end of the spiral elastic, and the coil spring can be bound to the hollow The sleeve also provides the concentricity and parallelism of the expansion sleeve of the hollow sleeve and (4). Therefore, according to the device of the invention, the device is simple, can reduce the manufacturing cost of 201204945, is easy to assemble, and reaches the component and the shaft of the application device. Equivalent to the requirements of concentric parallel, etc. [Embodiment] The following is an embodiment of the apparatus of the present invention for use in an azimuth mark of an optical and magnetic angle encoder. Please refer to the optical encoder sensing mark of Figures 4a and 4b for the implementation of 9 cases 'and 5a' 5b. The magnetic encoder type sensing mark is shown in the perspective view of the optical or magnetic sensor. The fixture assembly 400, 500 has a hollow sleeve 4〇6, 506'. One end of the hollow sleeve 406, 506 is used to set the sensor mark 4〇2, 502, that is, the component to be applied (such as the latter) Said), the other end has a plurality of parallel splits 408, 508 to improve the flexibility of the hollow sleeve, and fit into the shaft, the split end of the hollow sleeve, with external spiral grooves 4 J 〇, 510, and a coil spring 412, 512 for screwing into the outer spiral grooves 41 〇, 5 1 中空 of the hollow sleeves 406, 506 to bind the hollow sleeve. As shown in Fig. 4a, the optical disc 402 has an optical scale 404 thereon as an orientation. The mark of the corner is read by the optical sensor to determine the azimuth angle, and the optical disk 402 is fixedly coupled to one end of the hollow sleeve 4〇6, as shown in FIG. 4b; and, as shown in FIG. 5a, the magnet 5〇2 Inserted into the fixed sleeve of the hollow sleeve 506, the magnet 5〇2 is radially filled with the north and south pole magnetic J·sheng as a square The angle of the corner, for the magnetic sensor to read the azimuth angle of 201204945. When assembled on the rotating shaft of the power machine (not shown), just put the hollow sleeves 406, 506 on the shaft of the power machine Pushing into the positioning. The restraining force of the coil springs 412, 512 will make the hollow sleeve concentric with the rotating shaft while fixing the relative position. The coil springs 412, 512 which strengthen the restraining force enter the spiral groove by the rotation # propulsion mode. For the combination of the outer periphery of the slot, referring to FIG. 3, it is more convenient and quicker to buckle the retaining ring groove 3〇8 with the c-shaped buckle 310 than the prior art. Therefore, the assembly and disassembly of the device are simpler according to the invention. In addition, the coil springs 412 and 510 have flexibility. When the hollow sleeve is expanded on the rotating shaft of the power machine, the coil spring can also expand, and the strain of the material of the hollow sleeve wall is reduced by φ 'stress. It also decreases. However, the method of clamping the hollow sleeve by the C-shaped buckle 3 1 习 is known. Referring to FIG. 3, since the external flexibility of the c-shaped buckle 3 1 〇 is limited, the bound hollow sleeve 3〇4 A small amount of expansion can be achieved. When the hollow sleeve 304 is expanded inside the shaft, all strains compress the inner wall of the buckle groove 308 to cause great strain and stress. Therefore, according to the present invention, the inner wall of the hollow sleeve is subjected to less strain and stress. According to the present invention, the coil springs 412, 5 12 themselves can be wound around the periphery of the hollow 201204945 sleeve, and the axial distribution range of the restraining force is longer than that of the conventional C-type buckle 310, thereby providing higher radial torque. To maintain the parallelism between the hollow sleeve shaft and the rotating shaft. Since the coil springs 412, 512 are wound around the periphery of the hollow sleeve, the radial distribution of the binding force exceeds 36 degrees, which is less than 360 degrees compared with the prior art c-type buckle 310, and High • Flexibility makes the outer wall of the hollow sleeve fit better than the C-type buckle. Thus, the radial restraining force angle distribution in accordance with the present invention is more uniform, thereby providing better control of the concentricity of the towel (4) and the power machine rotating shaft. Finally, since the helical magazines 412 and 512 are larger in axial length and radial angle than the C-shaped buckle 310, the surface of the binding force is also larger than that of the C-shaped buckle, so the stress and strain limit in the plastic is limited. The binding force provided by the lower art is greater, so the present invention can provide a larger beam force. In summary, according to the present invention, the device is simple, easy to assemble and disassemble, and the inner wall of the hollow sleeve is subjected to less strain and stress, and the sleeve shaft and the rotating shaft can be kept parallel to each other, and the sleeve and the rotating shaft are concentrically larger and larger. The strength of the binding force. The above is an embodiment in which the present invention is applied to an azimuth mark of an optical and magnetic angle encoder. However, the present invention is not limited to the above description, but may allow various modifications and changes, but the present invention It will be covered by the equivalent meaning and scope of the scope of the patent application.
