DETAILED DESCRIPTION

[0021] In order to make the purpose, technical scheme of the present application clear, complete and the advantage more clear and apparent, the following will be further detailed with the drawings to the embodiment of the present application.It should be understood that the specific embodiment described here is a part of the embodiment of the present application, not all the embodiment, only to explain the embodiment of the present application, and not for limiting the embodiment of the present application, all other embodiments obtained by the ordinary skill in the art without doing creative work, belong to the scope of the present application.

[0022] Please refer to Figures 1 to 4 The utility model provides a kind of technical scheme:

[0023] Embodiment one, a tool fixture for precision laser cutting machine, for precision laser cutting machine tool fixture includes: laser cutting machine main part 1.

[0024] Specifically, a working groove 11 is provided on the upper side of the laser cutting machine body 1. Two clamping plates 2, both arranged in an "I" shape, are slidably connected to the inner side of the working groove 11, allowing relative sliding movement. A long strip steel plate 3 is slidably inserted into one side of the laser cutting machine body 1, between the two clamping plates 2. After the clamping plates 2 slide, they can clamp the long strip steel plate 3, thereby constraining the sliding trajectory of the long strip steel plate 3 and keeping it relatively fixed. Multiple No. 1 rollers 4 are rotatably connected to one side of the long strip steel plate 3. One end of the elongated steel plate 3 is rotatably connected to multiple second rollers 5. These second rollers 5 are symmetrically distributed at both ends of the working groove 11, and the elongated steel plate 3 is in contact with both the first roller 4 and the second rollers 5. The second rollers 5 support the elongated steel plate 3, keeping it suspended, thus facilitating laser cutting. Furthermore, the rotatable installation of the first roller 4 and the second rollers 5 reduces friction during linear sliding of the elongated steel plate 3, making it easier to operate. One side of the working groove 11 is rotatably connected to... A tilted clamping plate 6 is provided. Torsion springs 7 are fixedly connected to both ends of the clamping plate 6 and the laser cutting machine body 1. A rubber pad 61 is fixedly connected to the end of the clamping plate 6 that contacts the elongated steel plate 3. The rubber pad 61 increases the friction between the clamping plate 6 and the elongated steel plate 3. The torque of the torsion springs 7 allows the clamping plate 6 to restrict the sliding of the elongated steel plate 3 through friction when the elongated steel plate 3 is not pushed by an external force. Furthermore, the tilted clamping plate 6 can effectively restrict the sliding of the elongated steel plate 3 through friction. The steel plate 3 slides into the inlet to prevent misalignment of the cutting area of ​​the long strip steel plate 3. If it is necessary to pull the long strip steel plate 3 to slide in the opposite direction, the clamping plate 6 can be manually pushed to rotate to release the constraint on the long strip steel plate 3. This allows the fixation of the long strip steel plate 3 to maintain both flexibility and stability. A support frame 9 for supporting the long strip steel plate 3 is fixedly connected to one side of the laser cutting machine body 1. The support frame 9 can support the part of the long strip steel plate 3 that does not enter the laser cutting machine body 1, making the long strip steel plate 3 more stable.

[0025] To facilitate the relative sliding motion of the two clamping plates 2, a lead screw 8 driven by a motor 81 is rotatably connected to one side of the main body 1 of the laser cutting machine of this application. The side of the lead screw 8 has two threaded grooves located in the working groove 11 and in opposite directions. The two clamping plates 2 are respectively threaded onto the two threaded grooves of the lead screw 8. The two symmetrical and opposite threaded grooves on the lead screw 8 can effectively drive the two clamping plates 2 to make relative sliding motion when the lead screw 8 rotates.

[0026] For the installation of the clamping plate 2, one side of the working groove 11 of the present application is communicated with two symmetrically arranged sliding grooves 16 for sliding connection of the clamping plate 2, the sliding grooves 16 can be attached to the shape of the clamping plate 2, limiting the clamping plate 2 to only linear sliding motion, and one side of the clamping plate 2 is provided with a threaded hole 21 for threaded insertion of the lead screw 8, the threaded hole 21 can allow the clamping plate 2 to be better installed on the threaded groove of the lead screw 8.

[0027] In order to facilitate the stability of the lead screw 8, one end of the laser cutting machine body 1 of the present application is fixedly connected with a fixed plate 12 for fixed installation of the motor 81, the fixed plate 12 can give the motor 81 an installation surface, one end of the lead screw 8 is fixedly connected with a limiting block 82 for limiting the sliding of the lead screw 8, the limiting block 82 can ensure that the lead screw 8 will not slide, and one end of the sliding groove 16 is communicated with an installation groove 17 for rotational installation of the lead screw 8, the installation groove 17 can better cooperate with the limiting block 82 to limit the sliding of the lead screw 8.

[0028] In order to better install the long strip steel plate 3, one side of the laser cutting machine body 1 of the present application is provided with an insertion slot 13 for sliding insertion of the long strip steel plate 3, the lower side of the insertion slot 13 is lower than the upper end of the second roller 5 and the upper side of the insertion slot 13 is in contact with the inserted long strip steel plate 3, which can ensure that the long strip steel plate 3 can be slidably inserted into the laser cutting machine body 1 while allowing the second roller 5 to better contact the long strip steel plate 3.

[0029] In order to facilitate the installation of the clamping plate 6 and the torsional spring 7, one side of the working groove 11 of the present application is fixedly connected with two symmetrically arranged connecting plates 14, the two connecting plates 14 are fixedly connected with a first shaft 15 for rotational installation of the clamping plate 6, and the two torsional springs 7 are located between the clamping plate 6 and the connecting plate 14 and are sleeved with the first shaft 15, which can allow the clamping plate 6 to be better rotationally installed on the laser cutting machine body 1, while also avoiding the laser cutting machine body 1 from hindering the rotation of the clamping plate 6.

[0030] In actual implementation, the long strip steel plate 3 can be first placed on the support frame 9, then slidably inserted into the insertion slot 13, then adjusted in position and placed on the second roller 5 after adjustment, then the cutting area is placed in the working groove 11 by continuing to push the long strip steel plate 3 to slide, and the long strip steel plate 3 in position will be in contact with the rubber pad 61, at this time the torsional force of the torsional spring 7 will cooperate with the friction between the rubber pad 61 and the long strip steel plate 3 to keep the long strip steel plate 3 relatively fixed on the laser cutting machine body 1 after stopping applying a pushing force to the long strip steel plate 3, after the cutting of the cutting area is completed, the next cutting area can be replaced by continuing to push the long strip steel plate 3, without the need to re-clamp and fix the long strip steel plate 3, which is very convenient.

[0031] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
