Description

Technical Field

[0001] The utility model relates to the technical field of wire winding, in particular to a tool for wire winding. Background Art

[0002] The winding wheel rotates to collect the wire and wind it on the winding ring surface of the winding wheel. In production practice, the wire that has not entered the winding wheel is often misplaced front to back with the winding wheel. In order to ensure that the wire can be wound on the winding ring surface, pressure plate wheels are usually provided on both sides of the winding wheel to avoid derailment. In the prior art, a wire passing groove is also provided on the pressure plate wheel to facilitate the threading of the wire head or tail. The setting of the wire passing groove makes the center of mass of the pressure plate wheel deviate from the rotation axis of the winding wheel. The eccentric vibration is large during the winding process, which makes the winding easy to loose and unstable. The large eccentric vibration is not conducive to improving the service life of the equipment and is easy to cause wear of parts. Loose winding can easily cause the wound wire to detach from the winding wheel, causing wear of the wire and increasing production costs. Utility Model Content

[0005] Based on the above technical solution, there are multiple balancing grooves extending radially.

[0006] On the basis of the above technical solution, the side edge of the pressure plate wheel close to the annular cavity includes a cut surface to guide the wire into the annular cavity from the outside and wind it on the winding wheel.

[0010] On the basis of the above technical solution, the two pressure plate wheels rotate synchronously with the winding wheel.

[0011] On the basis of the above technical solution, it also includes a shaft rod, which passes through the winding wheel and can transmit the rotational motion to the winding wheel, and the two pressure plate wheels are arranged outside the shaft rod through bearing sleeves.

[0012] Beneficial Effects

[0013] The utility model has a reasonable structure. The two pressure plate wheels are arranged on both sides of the winding wheel and form an annular cavity to prevent the wire from escaping from the winding ring surface. In addition, a balancing groove is provided on the pressure plate wheel, and the size of the balancing groove can be adaptively adjusted according to the size of the wire passing groove so that the center of mass of the pressure plate wheel is on the rotation axis of the winding wheel.

[0027] like Figures 1 to 5 The winding tool shown in FIG. 1 comprises two pressure plate wheels 1 arranged opposite to each other, as shown in FIG. Figure 1 The two pressure plate wheels 1 are arranged on both sides of the winding wheel 100 and form an annular cavity 5 together with the winding ring surface of the winding wheel 100. Specifically, the cross section of the pressure plate wheel 100 is roughly in the shape of an "I". The winding ring surface of the pressure plate wheel 1 is provided with a winding cavity, which is the same width as the annular cavity 5, and also includes a shaft 200, which passes through the winding wheel 100 and can transmit the rotational motion to the winding wheel 100. Figure 2 and 3 As shown, the pressure plate wheel 1 near the motor is integrally formed and includes a central through hole for the shaft 200 to pass through, and the shaft 200 can transmit the rotational motion to the pressure plate wheel 1;

[0028] like Figure 1 and 5 As shown, the other pressure plate wheel 1 is provided with a plurality of connection holes, and the screw rod can pass through the connection holes to be fixedly connected with the winding wheel 100, so that the two pressure plate wheels 1 can rotate synchronously with the winding wheel 100.

[0029] like Figure 2 and 4 As shown, the pressure plate wheel 1 includes a radially extending wire groove 2. After the winding is completed, the wire end of the wire can be passed through the wire groove 2 to facilitate the picking up of the wire end during use. The wire groove 2 forms a wire notch on the outer side of the pressure plate wheel 1 to facilitate the removal of the wire end. The winding wheel 100 is also provided with a balance groove 3. In this embodiment, as shown in FIG. Figure 3 and 5 As shown, there are two balancing grooves 3 extending radially, and the two balancing grooves 3 are designed so that the center of mass of the pressure plate wheel 1 is on the rotation axis of the winding wheel. This can avoid large eccentric vibrations during the winding process, which is beneficial to increasing the service life of the equipment. At the same time, it can avoid the situation of loose winding, avoid the situation of the wound wire escaping from the winding wheel, and avoid the situation of the wire being worn, which is beneficial to reducing production costs. In other embodiments of the present invention, a slider 31 can be further provided in the balancing groove 3 to adaptively adjust the center of mass of the pressure plate wheel 1 to compensate for the deviation of the center of mass from the set position caused by the processing error of the pressure plate wheel 1, and the use flexibility is good, wherein the slider 31 is adjustable in the balancing groove 3 along the axial position of the balancing groove 3, such as the slider is adsorbed on the inner wall surface of the balancing groove 3 under the action of magnetic force.

[0030] like Figure 1As shown, the side edge of the pressure plate wheel 1 near the annular cavity 5 includes a cut surface 4, which can increase the opening of the annular cavity 5, guide the wire from the outside into the annular cavity 5 and wind it on the winding wheel 100, and also guide the wire on it to be wound on the winding wheel 100 near the middle position to improve the winding quality. In this embodiment, the cut surface 4 and the outer side surface of the pressure plate wheel 100 connected to the cut surface 4 include smooth surfaces to reduce the friction effect on the wire.

[0031] like Figure 2 and 4 As shown, the end surface of the pressure plate wheel 1 facing the winding wheel includes an annular groove 6, and the winding wheel 100 can be partially embedded in the annular groove 6 to radially position the winding wheel 100, and when the winding wheel 100 is embedded in the annular groove 6, the lower end of the cross-section 4 is close to the winding annular surface of the winding wheel 100, so that the winding stability is good.

[0032] The outer wall of the pressure plate wheel 1 in this embodiment is flat to prevent the wire that fails to fall into the annular cavity 5 from being wound around the portion outside the pressure plate wheel 1.

[0033] Example 2

[0034] The present embodiment differs from the first embodiment in that it further comprises a shaft 200, which passes through the winding wheel 100 and can transmit the rotational motion to the winding wheel 100. The two pressure plate wheels 1 are arranged outside the shaft 200 through bearing sleeves, that is, the winding wheel 100 and the two pressure plate wheels 1 do not rotate synchronously. Even if the pressure plate wheel 1 rotates under the action of inertia and its rotation speed is lower than that of the winding wheel 100, the influence of the pressure plate wheel 1 on the winding wheel 100 when the center of mass of the pressure plate wheel 1 deviates from the rotation axis of the winding wheel 100 can be further reduced.

[0035] The present invention is described above by way of examples, but the present invention is not limited to the above specific embodiments, and any changes or modifications based on the present invention belong to the scope of protection required by the present invention.
