The wires can be placed on the lower clamping plate, and multiple lower clamping plates can be used to place multiple wires. The wires can be arranged and distinguished for easy maintenance. After the wires are placed, the rotating shaft can be rotated to drive the screw to rotate through the first bevel gear and the second bevel gear, thereby causing the slider to move downward in the vertical groove, thereby driving the upper clamping plate to descend, so that the upper and lower clamping plates fit together, clamping and wrapping the wires, and protecting the wires.

[0004] The above-mentioned prior art solution has the following shortcomings: the wires are placed on multiple lower clamping plates, and the upper clamping plates are lowered by rotating the screw to clamp the wires.

At the same time, the gap between the upper and lower clamping plates is fixed, so it can only accommodate wires within a specific diameter range. Wires with smaller or larger diameters may not be effectively clamped, and may even become loose or damaged. Utility Model Content

DETAILED DESCRIPTION

[0022] The technical scheme in the utility model embodiment will be described clearly and completely in the following with reference to the drawings in the utility model embodiment, obviously, the described embodiment is only a part of the embodiment of the utility model, not all the embodiment. Based on the embodiment in the utility model, all other embodiments obtained by the person skilled in the art without making creative labor belong to the scope of the utility model protection.

[0023] First embodiment

[0024] Referring to Figures 1 to 4 As shown in the figure, an electrical protection device of an automatic numerical control machine tool comprises a bottom plate 1, the top of the bottom plate 1 is fixedly provided with a plurality of clamping assemblies 2 arranged longitudinally, the clamping assembly 2 comprises a bracket 3, a first clamping block 4, a second clamping block 5 and a wedge-shaped sliding block 6, the side of the bracket 3 is provided with a vertical sliding groove 7 and a horizontal sliding groove 8, and the vertical sliding groove 7 and the horizontal sliding groove 8 are communicated, the first clamping block 4 and the second clamping block 5 are slidably arranged in the vertical sliding groove 7, and one end of the first clamping block 4 and the second clamping block 5 extends into the horizontal sliding groove 8, the wedge-shaped sliding block 6 is slidably arranged in the horizontal sliding groove 8, and the top and the bottom of the wedge-shaped sliding block 6 are respectively provided with a first wedge-shaped groove 9 and a second wedge-shaped groove 10, the first clamping block 4 and the first wedge-shaped groove 9 are slidably matched, the second clamping block 5 and the second wedge-shaped groove 10 are slidably matched, and the first clamping block 4 and the second clamping block 5 are provided with slots staggered with each other.

[0025] When it is needed to clamp the electric wire in the device, the corresponding wedge-shaped sliding block 6 is first slid to move in the horizontal sliding groove 8. Since the top and the bottom of the wedge-shaped sliding block 6 are respectively provided with the first wedge-shaped groove 9 and the second wedge-shaped groove 10, and the first clamping block 4 and the first wedge-shaped groove 9 are slidably matched, and the second clamping block 5 and the second wedge-shaped groove 10 are slidably matched, when the wedge-shaped sliding block 6 moves, the first clamping block 4 and the second clamping block 5 will be relatively slid in the vertical sliding groove 7. With the continuous movement of the wedge-shaped sliding block 6, the distance between the first clamping block 4 and the second clamping block 5 will gradually decrease until the electric wire is clamped tightly. When it is needed to release the electric wire, the wedge-shaped sliding block 6 is only needed to be slid reversely, so that the distance between the first clamping block 4 and the second clamping block 5 is increased, thereby realizing the release of the electric wire.

[0026] In particular, the first clamping block 4 and the second clamping block 5 are provided with slots staggered with each other, which not only increases the contact points between the clamping block and the electric wire, improves the stability of clamping, but also provides a certain elastic space for the electric wire, so that it can adapt to electric wires of different diameters without causing too tight or too loose clamping effect.

[0027] The utility model discloses the adjustment of the distance between the first clamping block 4 and the second clamping block 5 is realized through the wedge-shaped sliding block 6, thereby the single electric wire can be independently clamped and released, avoids the complicated operation of untying the whole electric wire bundle when repairing or replacing a certain electric wire, reduces the complexity and time cost of the operation of overhauling. Meanwhile, since the first clamping block 4 and the second clamping block 5 are provided with slots staggered with each other, and the distance between them can be adjusted through the sliding of the wedge-shaped sliding block 6, therefore the device can adapt to electric wires of different diameters, improves the flexibility and universality of use.

[0028] Second embodiment

[0029] See also Figure 2 、 Figure 3 and Figure 4 As shown, based on the first embodiment, the first clamping block 4 includes a first slide 11 and a first clamping plate 12, the first clamping plate 12 being hinged to the first slide 11 and being rotationally connected to the first slide 11 via a rotation axis, and the second clamping block 5 includes a second slide 13 and a second clamping plate 14, the second clamping plate 14 being hinged to the second slide 13 and being rotationally connected to the second slide 13 via a rotation axis. The first slide 11 and the second slide 13 are relatively slidably arranged in the vertical slide groove 7 and are slidably engaged with the first wedge groove 9 and the second wedge groove 10, respectively. The first clamping plate 12 and the second clamping plate 14 are provided with slots that are staggered with each other.

[0030] By rotating the first clamping plate 12 and the second clamping plate 14 on the first slide 11 and the second slide 13, maintenance personnel can more conveniently place the cable between the first clamping plate 12 and the second clamping plate 14. This simplifies the installation process of the wires and improves the installation speed. Specifically, before placing the cable between the first clamping plate 12 and the second clamping plate 14, it is only necessary to rotate the first clamping plate 12 and the second clamping plate 14 so that the openings of the first clamping plate 12 and the second clamping plate 14 face outward to easily place the wire. After placing the wire, the first clamping plate 12 and the second clamping plate 14 are rotated again so that the slots of the first clamping plate 12 and the second clamping plate 14 cooperate with each other. Then, by sliding the wedge-shaped slider 6, the distance between the first slide 11 and the second slide 13 is adjusted to achieve the clamping and fixing of the wire by the first clamping plate 12 and the second clamping plate 14.

[0031] Third embodiment

[0032] See also Figure 2 、 Figure 3 and Figure 4 As shown, based on the first embodiment, the vertical chute 7 is fixedly mounted in the guide rod 15, and the first clamping block 4 and the second clamping block 5 are both slidably connected to the guide rod 15. A first spring 16 and a second spring 17 are wound around the side of the guide rod 15. One end of the first spring 16 is connected to the vertical chute 7, and the other end of the first spring 16 is connected to the first clamping block 4. One end of the second spring 17 is connected to the vertical chute 7, and the other end of the second spring 17 is connected to the second clamping block 5. A third spring 18 is mounted in the horizontal chute 8. One end of the third spring 18 is connected to the horizontal chute 8, and the other end of the third spring 18 is connected to the wedge-shaped slider 6.

[0033] When the first clamp 4 and the second clamp 5 are clamping the wire or when the first clamp 4 and the second clamp 5 are closed, the first spring 16, the second spring 17 and the third spring 18 are all in a slightly compressed state and support the first clamp 4, the second clamp 5 and the wedge slide 6. When the wire needs to be released, the wedge slide 6 can be pressed to slide into the horizontal slide 8. At the same time, the first clamp 4 and the second clamp 5 slide with the first wedge groove 9 and the second wedge groove 10 respectively, so that the first clamp 4 and the second clamp 5 slide like the ends of the vertical slide 7. At this time, the first spring 16, the second spring 17 and the third spring 18 are further compressed until the pressure on the wedge slide 6 is released. The elastic force of the first spring 16, the second spring 17 and the third spring 18 will respectively push the first clamp 4, the second clamp 5 and the wedge slide 6 back to their respective initial positions, so that the first clamp 4 and the second clamp 5 can clamp the wire or close the first clamp 4 and the second clamp 5.

[0034] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
