Device for detecting oscillation condition of steel wire of one rim and rim tension measuring machine having the same

The present invention relates to the measurement of the tension of a wire of a bicycle rim, and more particularly to a device for detecting an oscillating condition of a wire of a rim and a rim tension measuring machine having the same.

There are many related designs for the equipment for detecting and correcting the rim of bicycle rims, such as Taiwan Announcement 166042, 263473, 303819, 445220, I255777, I256922, I400168, I468683, M502827, M500885 and Taiwan Public 201224424 and 201139166. Etc., and particularly for the detection and adjustment of the tension of the steel wire (or spoke) of the rim, there are currently known Taiwan Announcement I542862, Taiwan Public 200835911, 201122450 and WO 97/45722 and the like. Among them, the 201122450 discloses a conventional rim measuring machine for measuring the tension of each of the wires 92 of the rim 9 shown in FIG. As shown in FIG. 14, the conventional rim measuring machine clamps the two ends of the mandrel 911 of the hub 91 of the rim 9 by the two collets 93, and uses the relative rotation of the two rollers 94 of a driving mechanism. The wheel frame 90 of the rim 9 is driven to rotate the entire rim 9 about the mandrel 911. During the rotation, the two sides of the wire 92 of the rim 9 will pass through the two picks P one by one, and will be oscillated by them. At this time, an oscillation detecting module 95 is triggered by the detection. Beam 950 detection The effective amplitude value of the wire 92 that has been oscillated until now is continuously converted by a computer control system (not shown) into a corresponding tension value, which represents the current dialed value. The tension to the wire 92.

In general, the depth of the portion A of each of the wires 92 that is moved by the corresponding paddle P should be as uniform as possible and "appropriate" (for example, as shown in Fig. 15), so that each wire 92 is subjected to The dialing power path will be as consistent as possible without being too big or small, so that the measured and converted tension will be more correct (or closer to the real tension). However, since the tightness (or tension) of each of the wires 92 of the rim 9 may not be exactly the same, the wheel frame 90 is not likely to be 100% flat, and therefore, the rim 9 is covered by the two rollers 94. When the driving is rotated, an axial yaw will inevitably occur. At this time, since the two chucks 93 have clamped the ends of the mandrel 911 of the hub 91 of the rim 9 to form a fixed point, the two rollers 94 will follow The axial yaw of the wheel frame 90 is shifted in the axial direction (see the Taiwan Patent Publication No. I400168). Therefore, during the rotation of the rim 9, the wheel frame 90 and the wire 92 are equivalent to the hub 91. The pivot point is slightly swung left and right (as indicated by reference numeral B in Fig. 14), and the amplitude of the swing of the portion of each of the wires 92 farther from the hub 91 is larger. Since the portion A of each of the wires 92 that is dialed by the corresponding paddle P is relatively far from the hub 91, the amplitude of the swing of the portion A of each of the wires 92 is relatively larger than that of the other closer portions. This may cause the depth of the portion A of each wire 92 to be dialed by the corresponding paddle P to be inconsistent and "inappropriate". For example, the wire 92a shown in Fig. 16 is correspondingly dialed. The depth to which the sheet P is dialed is too shallow, and the wire 92b shown in Fig. 17 is not dialed at all by the corresponding paddle P, and the depth of the wire 92c shown in Fig. 18 by the corresponding paddle P is too In short, in short, the depth of the wire 92 of the rim 9 is different by the paddle P, resulting in a difference in the force of each wire 92 being dialed by the corresponding paddle P, and it is even possible to have a wire often 92 is not dialed, causing the tension measurement is not accurate enough, so the conventional rim measuring machine is still necessary for improvement.

It is known in the prior art that the conventional rim measuring machine adopts a method of fixing the center of one of the rims to be measured while allowing its outer circumference to be freely axially yawed, which will cause each wire of the rim to be phased. The depth of the corresponding dial may be inconsistent and "inappropriate", causing the difference in the force of each wire of the rim to be dialed by the corresponding pad, and it may even be that the wire is not dialed frequently. The situation that causes the tension measurement to be less accurate.

In view of the above, the present invention provides a device for detecting an oscillation condition of a wire of a rim and a rim tension measuring machine provided with the device, so that the wire tension measurement result can be equivalent to or closer to the wire wire.

At this time, the detecting mechanism 6 immediately detects the oscillation condition of the wire 92 that is currently dialed by the detected detecting beam (for example, a red or blue laser beam), and transmits the detection result to the detection result. The computer control device calculates, by the computer control device, a corresponding force value according to the detection result, and the tension value represents the tension of the wire 92 that is currently dialed. Regarding the process of the detection mechanism 6 and the aforementioned calculation of the tension value, reference may be made to the applicant's previous invention patent of Taiwan Patent No. 201122450, which is not described herein. In addition, the detecting mechanism 6 can be disposed on the second sliding seat 72 of the adjusting mechanism 7 as shown in FIGS. 11 and 12 (it can also be directly disposed on the front side wall 201 of the machine table 1).

The foregoing mechanism and operation principle of the rim drive mechanism 4 of the present invention is similar to the applicant's previous Taiwan I400168 invention patent. The difference between the two is mainly because the rim drive mechanism 4 of the present invention is fixed (or fixed after adjusting its position), and does not axially follow the axial yaw of the rim 9. Moving, but the wheel drive mechanism of the Taiwan I400168 invention patent has a moving portion that can be axially displaced with the axial yaw of the rim 9.

As shown in Fig. 11, in the above-described tension measurement of the wire 92 of the rim 9, the ends of the mandrel 911 of the hub 91 of the rim 9 are clamped by the chucks 321 of the two clamps 32, And the two clamps 32 can elastically move left and right axially with the respective slides 31 by using the elastic members 34 and the spacing S as described above, and the wheel frame 90 of the rim 9 is because of the rim The two rollers 40 of the drive mechanism 4 are sandwiched, and the entire rim drive mechanism 4 is fixed to the second carriage 72 without axial movement in accordance with the axial yaw of the rim 9. In short, in the process of measuring the tension of the wire 92 of the rim 9, the center of the rim 9 in rotation will move slightly with the axial yaw of the rim 9, but away from the The wheel frame 90 at the center of the rim 9 does not move axially with the axial yaw of the rim 9, and therefore, in the foregoing process, the hub 91 and the wire 92 of the rim 9 correspond to the wheel frame 90. A small left and right axial swing is made for the pivot point, and the swinging portion of the portion where each of the wires 92 is closer to the hub 91 is larger, but the swinging portion of the portion farther from the hub 91 is smaller. Since the portion of each of the wires 92 that is moved by the corresponding paddle 52 is relatively far from the hub 91, the amplitude of the swing of the portion of each of the wires 92 is relatively small compared to other closer portions. Therefore, the depth of the portion of each of the wires 92 is relatively consistent and "appropriate" by the corresponding paddle 52, resulting in a uniform force for each wire 92 being dialed by the corresponding paddle 52, and not It may or may not be easy to see that the wire 92 is not dialed, so the rim tension measuring machine of the present invention is more accurate (or closer to the true tension) in the wire tension measurement than the prior art.
