[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0026] Example 1
[0027] like Figure 1 As shown;
[0028] The laser cutting fixture comprises a support 1, a lateral displacement component 3 arranged on the support 1 through a support plate 2, and a longitudinal displacement component 4 arranged on the lateral displacement component 3, wherein a laser cutting machine 5 is installed on the longitudinal displacement component 4.
[0029] In this embodiment: In order to solve the technical problems existing in the prior art, as disclosed in the background technology above, "the current laser cutting machine clamp cannot clamp materials of different specifications due to the fixed setting of the clamp when fixing the material", combined with actual use, this problem is obviously a real problem that is difficult to solve. Therefore, in order to solve this technical problem, a span adjustment component 7 is added on this basis.
[0030] like Figure 1-Figure 4 As shown;
[0031] In combination with the above content, in order to facilitate the clamping of materials of different specifications, it also includes a front-rear displacement component 6 arranged on the support 1, and the front-rear displacement component 6 is provided with a span adjustment component 7, and the span adjustment component 7 is provided with a left clamp mechanism 8 and a right clamp mechanism 9.
[0032] In an optional embodiment, the span adjustment component 7 includes a limit seat 71 fixed on the top of the front and rear displacement component 6, and a cross slide hole 72 is opened on the limit seat 71. A screw rod 73 is transversely penetrated inside the cross slide hole 72, and a left cross slider 74 and a right cross slider 75 are arranged inside the cross slide hole 72. A reduction motor 76 is fixedly installed on the right side wall of the limit seat 71, and the rotor of the reduction motor 76 is connected to the screw rod 73. The left and right ends of the screw rod 73 have opposite thread directions, and the left cross slider 74 and the right cross slider 75 are respectively screwed on the threads of different directions on the left and right ends of the screw rod 73, and the left clamp mechanism 8 and the right clamp mechanism 9 are fixed on the top of the left cross slider 74 and the right cross slider 75.
[0033] In this embodiment: the reduction motor 76 and the electric screw 73 rotate. Since the left cross slider 74 and the right cross slider 75 are respectively screwed on the threads of different directions at the left and right ends of the screw 73, and the left cross slider 74 and the right cross slider 75 are limited by the cross slide hole 72, the rotation of the screw 74 drives the left cross slider 74 and the right cross slider 75 to move in opposite directions, and then drives the left clamp mechanism 8 and the right clamp mechanism 9 to move in opposite directions, which is convenient for clamping materials of different specifications and has strong flexibility.
[0034] In an optional embodiment, the left clamp mechanism 8 and the right clamp mechanism 9 have the same structure and size, and are symmetrically arranged on the left and right. The left clamp mechanism 8 includes a U-shaped bracket 81 fixed to the top of the left cross slider 74, and a locking bolt 82 is screwed on the U-shaped bracket 81.
[0035] In an optional embodiment, the lateral displacement assembly 3, the longitudinal displacement assembly 4 and the front-rear displacement assembly 6 have the same structure and operating principle. The lateral displacement assembly 3 includes a U-shaped seat 31 fixed on the support plate 2, and a first screw 32 and a pair of guide rails 33 are transversely arranged between the two ends of the U-shaped seat 31 through bearings. A moving block 34 that slides left and right on the guide rails 33 is screwed on the first screw 32, and a first reduction motor 35 is fixed to the right side wall of the U-shaped seat 31, and the rotor of the first reduction motor 35 is connected to the first screw 32.
[0036] In this embodiment: the lateral displacement component 3, the longitudinal displacement component 4 and the front-rear displacement component 6 have the same structure and operating principle, and all of them drive the displacement blocks to move in different directions through the action of screws, and they are all existing well-known technologies, which are recorded in both the patent network and public documents, and will not be elaborated on again.
[0037] The working principle of the utility model is as follows: the material is placed between the left clamp mechanism 8 and the right clamp mechanism 9, and the two ends of the material are fixed on the left clamp mechanism 8 and the right clamp mechanism 9 by rotating the locking bolt 82. The cooperation of the front and rear displacement components 6 and the lateral displacement components 3 and the longitudinal displacement components 4 enables the laser cutting machine 5 to cut the specified position of the material. When cutting materials of different specifications, the electric screw 73 is rotated by the reduction motor 76. Since the left cross slider 74 and the right cross slider 75 are respectively screwed on the threads of different directions at the left and right ends of the screw 73, and the left cross slider 74 and the right cross slider 75 are limited by the cross slide hole 72, the rotation of the screw 74 drives the left cross slider 74 and the right cross slider 75 to move in opposite directions, thereby driving the left clamp mechanism 8 and the right clamp mechanism 9 to move in opposite directions, which is convenient for clamping materials of different specifications and has strong flexibility.
[0038] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
