[0025] Example 1: Refer to Figure 1 , Figure 2 This invention proposes an anti-jamming electrode wire clamping and feeding device, including a clamping wheel assembly for clamping and feeding the electrode wire 100, and a clutch drive mechanism for driving the clamping wheel assembly to clamp / disengage. The clutch drive mechanism includes a mounting base (not shown in the figure) and a slider 1 connected to the clamping wheel assembly. The slider 1 can translate under the driving action of the clutch drive mechanism to drive the clamping wheel assembly to clamp / disengage. A limiting mechanism is provided between the slider 1 and the mounting base. The limiting mechanism includes a limiting shaft 2 parallel to the translation direction of the slider 1. The limiting shaft 2 can act on the slider 1 to restrict its vertical movement space during translation. The limiting shaft 2 has higher machining precision. Using the limiting shaft 2 to limit the vertical space of the slider 1 during translation is more accurate than directly using a groove to limit the slider 1. Using the limiting shaft 2 for limiting can result in smaller gaps and less metal shavings intrusion, effectively avoiding jamming or even stuck failures.
[0026] Specifically, the limiting mechanism includes a limiting block 3 adapted to the limiting shaft 2. The limiting shaft 2 is connected to the slider 1, and the limiting block 3 is connected to the mounting base. The limiting block 3 has a limiting hole 8 in its middle that is adapted to the outer diameter of the limiting shaft 2, and the limiting shaft 2 passes through the limiting hole 8. The mounting base has a sliding groove for the slider 1 to move horizontally. There is a preset first gap between the inner wall of the sliding groove and the outer wall of the slider 1 to prevent them from rubbing against each other. By setting the first gap, the slider 1 is suspended relative to the sliding groove, which can effectively prevent the slider 1 from getting stuck when moving horizontally in the sliding groove. The two symmetrical end faces of the slider 1 are both recessed with grooves 4, and the limiting shaft 2 is located in the grooves 4. The limiting shaft 2 is symmetrically located on both sides of the slider 1, making the slider 1 move more smoothly. There is a preset second gap between the outer wall of the limiting block 3 and the inner wall of the groove 4 to prevent them from rubbing against each other. By setting the second gap, it is ensured that the slider 1 is suspended and not affected by the limiting block 3. The limiting block 3 is rectangular, allowing for a better fit with the mounting base and a more stable connection structure. The limiting shaft 2 is cylindrical, and the limiting hole 8 has a circular cross-section. Both cylindrical and circular shapes can be precisely machined using wire cutting to ensure higher accuracy and smaller gaps, thus minimizing the infiltration of metal shavings and preventing jamming. The clutch drive mechanism includes a translation drive mechanism (not shown in the figure), the output end of which is connected to the slider 1. The clamping wheel set includes a drive wheel set 5 and a driven wheel set 6. The drive wheel set 5 is connected to a drive motor (not shown in the figure) that drives its rotation, and the driven wheel set 6 is connected to the slider 1 via a connecting shaft 7.
[0027] The working principle of this embodiment:
[0028] When it is necessary to clamp the electrode wire 100, the translation drive mechanism drives the slider 1 to translate. Under the cooperation of the limiting shaft 2 and the limiting block 3, the slider 1 performs precise translation. The slider 1 drives the driven wheel group 6 to translate to the driving wheel group 5 through the connecting shaft 7, so that the clamping wheel group can clamp the electrode wire 100. Under the drive of the drive motor, the driving wheel group 5 drives the driven wheel group 6 to rotate synchronously in the opposite direction, so as to clamp the electrode wire 100.
[0029] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
