[0025] The following is combined with Figures 1-3 This invention describes an automatic wire rope tension adjustment device.

[0026] like Figure 1As shown in the embodiment of this utility model, the automatic wire rope tensioning adjustment device includes: a slider 10, a connector 20, a first fixing member 30, a second fixing member 40, an elastic member 50, and a roller 60. The central axis of the roller 60 is rotatably connected to the slider 10, allowing the roller 60 to rotate, and one end of the wire rope is wound around the roller 60. The first end of the connector 20 is connected to the slider 10, and the second end of the connector 20 passes through the second fixing member 40 and is connected to the first fixing member 30, and the connector 20 is movable relative to the second fixing member 40. The two ends of the elastic member 50 are respectively connected to the first fixing member 30 and the second fixing member 40. When the elastic member 50 extends, it can drive the connector 20 to move, thereby driving the slider 10 to move, so as to tension the wire rope.

[0027] Specifically, in this embodiment, the second fixing member 40 can be mounted on the machine tool. In the initial state, the elastic member 50 is in a compressed state, and the wire rope is in a tensioned state. When the wire rope becomes slack, the elastic member 50 extends under the action of elastic force, pushing the first fixing member 30 to move away from the second fixing member 40. The first fixing member 30 drives the connecting member 20 to move, which in turn drives the slider 10 to move, thereby increasing the distance between the roller 60 and the other end of the wire rope, thus tensioning the wire rope.

[0028] In this embodiment, the first fixing member 30 can be a plate; the second fixing member 40 can be a plate or a box. When the second fixing member 40 is a box, the elastic member 50 is connected to the inner wall of the box, and the second ends of the first fixing member 30 and the connecting member 20 are located inside the box.

[0029] In this embodiment, the elastic element 50 can be sleeved on the outside of the connector 20 or disposed on both sides of the connector 20.

[0030] The automatic wire rope tension adjustment device provided in this embodiment of the utility model, by setting up a slider, roller, connector, first fixing member, second fixing member and elastic member, can use the elastic force of the elastic member to drive the slider to move, and then automatically tighten the wire rope when it is slack, realizing automatic adjustment of wire rope tension, eliminating the need for manual operation, ensuring the continuity of production and improving production efficiency.

[0031] like Figure 2As shown, in an embodiment of this utility model, the slider 10 is provided with a first groove 101, which penetrates one end of the slider 10. A roller 60 is disposed within the first groove 101, and the central axis of the roller 60 is rotatably connected to the bottom of the first groove 101, allowing the roller 60 to rotate relative to the slider 10. In this embodiment, the first groove 101 penetrates one end of the slider 10, allowing the wire rope to extend into the first groove 101 and wrap around the roller 60. Optionally, in an embodiment of this utility model, the first groove 101 can be an arc-shaped groove or a rectangular groove, as long as it does not affect the rotation of the roller 60.

[0032] like Figure 3 As shown, in an embodiment of this utility model, the automatic wire rope tension adjustment device further includes a rotating shaft 61 and a bearing 62. The rotating shaft 61 is connected to the bottom of the first groove 101, the roller 60 is sleeved on the outside of the rotating shaft 61, and the bearing 62 is disposed between the rotating shaft 61 and the roller 60 to allow the roller 60 to rotate freely. Optionally, the bearing 62 can be a deep groove ball bearing.

[0033] like Figure 1 As shown, in an embodiment of this utility model, the automatic wire rope tension adjustment device further includes a guide seat. The guide seat has a first through groove along the movement direction of the slider 10. The slider 10 is disposed in the first through groove and can move relative to the guide seat. In this embodiment, the guide seat is disposed on and fixed to the machine tool. When the elastic member 50 extends, it can drive the slider 10 to move along the guide seat. Optionally, in this embodiment, the guide seat can be an integral structure or a split structure.

[0034] Furthermore, such as Figure 1 As shown, the guide seat is a split structure, which includes a pair of guide blocks 70. The pair of guide blocks 70 are arranged opposite each other. The surfaces of the pair of guide blocks 70 facing each other are provided with second through grooves 701. The pair of second through grooves 701 form a first through groove. The two sides of the slider 10 are embedded in the two second through grooves 701. The two second through grooves 701 form a track for the slider 10 to move, so as to guide the movement of the slider 10, so that the slider 10 moves smoothly, thereby tensioning the wire rope.

[0035] like Figure 1 As shown, the automatic wire rope tension adjustment device also includes a pair of guide rails 71, each guide rail 71 being disposed within a second through groove 701. The surfaces of the pair of guide rails 71 facing each other are provided with a third through groove 711 along the movement direction of the slider 10. The extending direction of the third through groove 711 is the same as the extending direction of the second through groove 701. The two sides of the slider 10 are embedded within the third through groove 711. The pair of third through grooves 711 form a track for the slider 10 to move. When the elastic member 50 extends, the slider 10 can move along the third through groove 711 to tension the wire rope.

[0036] The automatic wire rope tensioning adjustment device provided in this embodiment of the utility model guides the movement of the slider by setting a pair of guide rails in the guide block, ensuring the smooth movement of the slider and thus ensuring the effective tensioning of the wire rope.

[0037] like Figure 1 As shown, in an embodiment of this utility model, the automatic wire rope tensioning adjustment device further includes a bushing 51, which is sleeved outside the connector 20. An elastic member 50 is sleeved outside the bushing 51, and the two ends of the elastic member 50 are respectively connected to the first fixing member 30 and the second fixing member 40.

[0038] like Figure 1 As shown, in this embodiment of the present invention, the second fixing member 40 is a box structure, and the second fixing member 40 is provided with a second groove 401. The second fixing member 40 is disposed adjacent to the guide seat, and the connecting member 20 passes through the wall surface of the second fixing member 40 and extends into the second groove 401. One end of the elastic member 50 is connected to the inner wall of the box structure. When the elastic member 50 extends, the second fixing member 40 remains stationary, and the connecting member 20 drives the slider 10 to move.

[0039] like Figure 1 As shown in the embodiment of this utility model, the automatic wire rope tension adjustment device further includes a third fixing member 80 and an adjustment component. The third fixing member 80 is connected to the second fixing member 40, and the adjustment component is connected to the third fixing member 80. The adjustment component is used to adjust the distance between the second fixing member 40 and the first fixing member 30 in the initial state so that the elastic member 50 is in a compressed state.

[0040] Furthermore, in an embodiment of this utility model, the adjusting assembly includes an adjusting member 91 and a fixing seat 92. The first end of the adjusting member 91 is threadedly connected to the third fixing member 80, and the second end of the adjusting member 91 is connected to the fixing seat 92. By adjusting the length of the adjusting member 91 screwed into the third fixing member 80, the distance between the third fixing member 80 and the fixing seat 92 can be shortened, thereby shortening the distance between the second fixing member 40 and the first fixing member 30, so that the elastic member 50 is in a compressed state.

[0041] Optionally, in an embodiment of this utility model, the adjusting member 91 can be a bolt.

[0042] The automatic wire rope tension adjustment device provided in this embodiment can automatically adjust the wire rope tension when the wire rope is slack, without stopping the machine tool. Moreover, the automatic wire rope tension adjustment device has a simple structure and low manufacturing cost, and meets the transmission requirements of wire ropes of different specifications of machine tools.
