The present invention relates to a chuck of winding machines aims to securely clamp different sizes of handgrip ends of different rods.
The conventional method for winding a leather band on fishing rods, golf clubs, suspension rods, wooden rods or the like generally has to coat a layer of adhesive on the rods first. In operation, the common practice is to coat the adhesive while the fishing rod is turning. Although such an approach can coat the adhesive on the fishing rod, in practice it still has problems during assembly or use, notably:
1. The center cannot be aligned precisely:
The fishing rod mounted on the winding machine cannot be maintained on a straight line. Horizontal alignment mostly is accomplished through visual measurement. It is difficult to make precise horizontal calibration.
2. Turning of the rod is undesirable:
Users have to turn the fishing rod by hands. The force is not evenly applied and the angular movement of the fishing rod also is not even. As a result, the coated adhesive and the wound leather band also are not even.
In view of the aforesaid disadvantages occurred to the conventional fishing rod winding machine, the primary object of the present invention is to provide a chuck of winding machines that has an anchor disk turnable clockwise and counterclockwise to move jaws coupled by teeth inwards or outwards, and a rotary ring coupled with the anchor disk turnable in a reverse direction to allow the jaws to securely clamp the handgrip end of different diameters of the rods so that fine tuning adjustment may be made according to various types of rods.
In another aspect, the invention provides a pliable cap to couple one side of the jaw so that it can clamp the handgrip end securely without causing damages and can increase life span of the jaw and clamp different sizes of handgrip of different rods.
The foregoing, as well as additional objects, features and advantages of the invention will be more readily apparent from the following detailed description, which proceeds with reference to the accompanying drawings.
Please referring to
The anchor disk 21 is circular and has a round opening 210 in the center on one side, and three wedge troughs 211 extended radially outwards from the round opening 210. Each wedge trough 211 has two parallel flanges 212 on two sides. The chuck disk 21 further has a recess 213 formed on another side. There is a strut 214 extended outwards from the center of recess 213. The strut 214 has a screw hole 215 which is co-axial with the round opening 210 that communicate with each other. The peripheral surface of the strut 214 has tenons 216 formed thereon from inside to outside at different diameters and an annular groove 217. The peripheral rim of the anchor disk 21 further has three round holes 218 to receive a tool for turning.
Each jaw 22 has a flat surface 220 on a front side and two flutes 221 on two opposite sides close to the front end to divide the jaw 22 in a front section 222 and a rear section 223. The flutes 221 may be coupled with corresponding ridges 252 formed on a pliable cap 25. The bottom side of the jaw 22 has a wedge neck 224 matching with the wedge trough 211 that has a plurality of arched teeth 225 formed on the bottom end spaced by the same interval 226.
The rotary ring 23 has round holes 230 formed on the perimeter to engage with tools for turning. It has a collar 231 extended from one side to wedge in the recess 213 of the anchor disk 21 to become one body. The collar 231 has a top surface with a helical flange 232 formed thereon that extends gradually from inside to outside. The helical flange 232 is bordered by a helical trough 233 to engage with the arched teeth 225 of the jaw 22. The collar 231 has an indented surface 234 and a bore 235 in the center to couple with the tenons 216 of the strut 214 to become one body. Thus the anchor disk 21 and the rotary ring 23 may be wedged and coupled together without deviating or loosening off.
The clip ring 24 is annular and made from elastic material and has latch members 240 on two ends.
Each pliable cap 25 has a cavity 250 to couple with the front section 222 of the jaw 22 and a conical section 251 on one side and the opposing ridges 252 on another side corresponding to the flutes 221 of the jaw 22.
By means of the construction set forth above, when the anchor disk 21 is coupled with the rotary ring 23, the teeth 225 may be wedged in the trough 233, and the tenons 216 of the strut 214 may be coupled with the indented surface 234 to enable the strut 214 to run through the bore 235, then the clip ring 24 may be wedged in the annular groove 217 of the strut 214 so that the rotary ring 23 may be coupled with the anchor disk 21 to become one body (referring to

In summary, the chuck according to the invention has a collar 231 on the rotary ring 23 to be coupled in the recess 213 of the anchor disk 21, and the collar 231 has a helical flange 232 on one side to wedge in the interval 226 of the teeth 225 of the jaws 22 so that when the anchor disk 21 is turned clockwise or counterclockwise, the helical flange 232 of the rotary ring 23 can move the jaws 22 from inside to outside, or from outside to inside to securely clamp the handgrip ends 30 and 30a of the rods 3 and 3a. As the jaws 22 may be moved in a fine-tuned manner, clamping damage of the handgrip ends 30 and 30a may be prevented.
