When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not denote a unique embodiment.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

The laser cutting machine according to one embodiment includes a beam 1, a machine tool 2, and a laser head (not shown) as shown in fig. 1. The machine tool 2 comprises a first machine tool body 3 and a second machine tool body 4 which are oppositely arranged, a first guide rail 5 which is in sliding fit with one end of the cross beam 1 is arranged on the first machine tool body 3, a second guide rail 6 which is in sliding fit with the other end of the cross beam 1 is arranged on the second machine tool body 4, and two ends of the cross beam 1 are connected to the machine tool 2 through the first guide rail 5 and the second guide rail 6 in a sliding fit mode. The laser head is arranged on the beam 1, and the laser head moves relative to the workpiece through the sliding of the beam 1 to complete the cutting of the workpiece.

Referring to fig. 2, the cross member 1 includes a sliding portion 100, an elastic connector 200, and a main body 300. The sliding portion 100 is mounted with a first sliding mechanism 400, and the first sliding mechanism 400 is slidably fitted with the first rail 5. The main body 300 has a first end 310 and a second end 320 opposite to each other, the first end 310 is connected to one end of the elastic connection member 200, the sliding portion 100 is connected to the other end of the elastic connection member 200, and the first end 310 and the sliding portion 100 are movably connected by the elastic connection member 200 capable of generating a certain deformation. The second end 320 is further provided with a second sliding mechanism 500, and the second sliding mechanism 500 is in sliding fit with the second bed 4 to realize the sliding of the beam 1 on the machine tool 2.

In the above cross beam 1, the second end 320 is directly connected to the second guide rail 6 in a sliding manner, and the second end 320 can be regarded as a fixed end of the sliding during the sliding of the cross beam 1, so as to be used as a reference for the movement of the cross beam 1. The elastic connection member 200 is further disposed in the sliding connection between the first end 310 and the first guide rail 5, and since the elastic connection member 200 has a certain deformation capability, the first end 310 can be regarded as a sliding movable end in the sliding of the cross beam 1, and is adjusted and compensated by the elastic connection member 200 with reference to the second end 320. When the first guide rail 5 and the second guide rail 6 are not parallel, the elastic connecting piece 200 will deform correspondingly according to the non-parallel amount, so as to compensate the distance change between the first guide rail 5 and the second guide rail 6, and prevent the first guide rail 5, the second guide rail 6 and the beam 1 from being pulled and deformed or even damaged.

In one embodiment, the elastic connection member 200 has a plate-like structure, and both ends of the elastic connection member 200 are connected to the end of the main body 300 and the side wall of the sliding part 100 by screws, respectively. Specifically, the side wall of the sliding portion 100 connected to the elastic connection member 200 extends in the same direction as the first guide rail 5, and the end of the main body 300 extends in a direction perpendicular to the first guide rail 5, so that the elastic connection member 200 is disposed at both ends of the main body 300 opposite to the sliding portion 100. In other embodiments, the elastic connecting member 200 may be disposed on the end surfaces of the sliding portion 100 and the main body 300 that are not opposite to each other, for example, both ends of the elastic connecting member 200 may be disposed on the end surface of the sliding portion 100 in the longitudinal direction and the end surface of the main body 300 in the width direction. Specifically, the elastic connection member 200 is made of elastic steel, and in other embodiments, the elastic connection member 200 may be made of metal with better elasticity.

In one embodiment, the length of the elastic connection member 200 is not less than the length of the end of the main body 300 along the sliding direction of the sliding part 100, and the elastic connection member 200 can connect all the edges of the main body 300 when being connected with the main body 300 because the length is long enough, so that the interaction force between the main body 300 and the elastic connection member 200 is more stable in the compensation of the movement process of the cross beam 1, and the adjustment effect is not affected because part of the main body 300 is not connected to the elastic connection member 200. Further, the elastic connection member 200 extends from the top surface of the main body 300 to the bottom surface of the sliding portion 100 in the vertical direction, which enables the area of the elastic connection member 200 covering the main body 300 and the sliding portion 100 to be larger and the connection to be more stable.

Referring to fig. 3, in one embodiment, the first sliding mechanism 400 includes a first slide 410 and a first driving assembly 420, the first slide 410 is mounted on a surface of the sliding portion 100 opposite to the first bed 3, and the first driving assembly 420 drives the first slide 410 to slide along the first guide rail 5 of the first bed 3. Specifically, the first driving assembly 420 includes a linear servo motor 421 and a speed reducer 422, which are in transmission connection, so as to adjust the sliding speed of the first end 310 on the machine tool 2 to the machining requirement.

Specifically, the second driving assembly 520 includes a linear servo motor (not shown) and a speed reducer (not shown) in transmission connection to adjust the sliding speed of the second end 320 on the machine tool 2 to the processing requirement. It should be noted that the driving speed output by the first driving assembly 420 to the first slide 410 is the same as the driving speed output by the second driving assembly 520 to the second slide 510, so as to ensure the synchronism of the movement of the two ends of the main body 300 on the machine tool 2.

The laser cutting machine further comprises a locking assembly, wherein the locking assembly is arranged on the second lathe bed 4 and used for locking and pressing the second guide rail 6 on the second lathe bed 4, so that the second guide rail 6 serves as a transmission reference. With the arrangement, when the sliding part 100 bears the acting force of the elastic connector 200, the auxiliary guide rail 8 can completely lean against the surface of the auxiliary guide rail 8, so that the deformation of the auxiliary guide rail 8 is prevented, the main guide rail 7 can completely lean against the surface of the main guide rail 7, the deformation of the main guide rail 7 is prevented, the acting force of the elastic connector 200, which can be better received by the first guide rail 5, can be transmitted and dispersed, and the stability of the first guide rail 5 is ensured.
