DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.

[0025] A sliding fit structure of a laser cutting machine fuselage and a cross beam, like Figure 1 and Figure 2, including two parallel moving tracks arranged on the upper end of the fuselage 1, the two moving tracks are distributed in upper and lower positions, and the distance between the moving track with higher height position and the front end face of the fuselage 1 is greater than that between the moving track with lower height position and the front end face of the fuselage 1, and the two moving tracks are slidably connected with the cross beam 11. The laser cutting head slides on the cross beam 11 to form a cutting seam on the material, which is not described here.

[0026] As Figure 1 and Figure 2 , the cross beam 11 is slidably connected with the fuselage 1 through the two moving tracks, which increases the connection area and connection strength between the cross beam 11 and the fuselage 1, thereby increasing the bearing capacity of the cross beam 11, and the two moving tracks are slidably connected with the cross beam 11 at different positions, so that the stability of the cross beam 11 and the fuselage 1 is increased when they are slidably connected.

[0027] As Figure 1 and Figure 2 , the two moving tracks are two rodless air cylinders 12 distributed along the length direction of the fuselage 1, the cross beam 11 is provided with a sliding plate 111 fixedly connected with a sliding block 121 on the rodless air cylinder 12, the fuselage 1 is provided with an inclined surface one 13 between the two rodless air cylinders 12, the cross beam 11 is provided with an inclined surface two 131 opposite to the inclined surface one 13, and a gap exists between the inclined surface one 13 and the inclined surface two 131. The fuselage 1 is provided with two vertical surfaces, the inclined surface one 13 is connected with the two vertical surfaces, and the two rodless air cylinders 12 are fixedly arranged on the two vertical surfaces respectively.

[0028] As Figure 1 and Figure 2 , the two sliding plates 111 are vertically distributed and fixedly arranged at the upper and lower ends of the inclined surface two 131 of the cross beam 11, and the fuselage 1 is provided with a support plate 14 below the two rodless air cylinders 12, the support plate 14 is distributed along the length direction of the rodless air cylinder 12, the sliding plate 111 is provided with a moving plate 141 slidably arranged along the length direction of the support plate 14, and the lower end surface of the moving plate 141 is embedded with a plurality of rolling balls abutting against the upper end surface of the support plate 14. When the rodless air cylinder 12 drives the cross beam 11 to move, the moving plate 141 moves on the support plate 14, and the rolling balls reduce the friction force of the moving plate 141 when moving on the support plate 14, and provide a supporting force for the cross beam 11, thereby further improving the stability of the cross beam 11 and increasing the bearing capacity of the cross beam 11.

[0029] As Figure 1 and Figure 3The inclined surface one 13 is provided with a triangular prism 15, one side of the triangular prism 15 is fixed with the inclined surface one 13, the other side is vertically distributed and provided with an L-shaped detection plate 151 on the side, the side of the crossbeam 11 is provided with an opposite plate 152 opposite to the detection plate 151, the opposite plate 152 is provided with a distance sensor 153, the vertical surface of the detection plate 151 is connected with the side of the triangular prism 15 through a fastening bolt, and one end of the horizontal surface is opposite to the distance sensor 153 on the opposite plate 152. The purpose of designing the above structure is that when the crossbeam 11 reciprocates along the rodless cylinder 12, the inclined surface two 131 moves relative to the inclined surface one 13, and the data A detected by the distance sensor 153 when passing through one end of the horizontal surface is the data of the crossbeam 11 normally installed on the fuselage 1, when the data A detected by the distance sensor 153 when passing through one end of the horizontal surface changes with the movement of the crossbeam 11, it indicates that the inclined surface two 131 is displaced or deformed, that is, the crossbeam 11 is displaced or deformed, and the crossbeam 11 needs to be reinstalled.

[0030] As Figure 1 and Figure 3 The number of triangular prisms 15 is several and is on the same straight line, that is, the number of detection points of the distance sensor 153 is increased, so that the detection is more accurate.

[0031] As Figure 1 and Figure 4 and Figure 5 Both ends of the supporting plate 14 are provided with mounting blocks 16 located on one side of the rodless cylinder 12, the two mounting blocks 16 are located at both ends of the rodless cylinder 12, and the two oppositely distributed mounting blocks 16 are provided with buffer pads 161 on the side facing each other, the buffer pads 161 extend to the rod body part of the rodless cylinder 12, and the supporting plate 14 is slidably connected with two buffer plates 17 located on both sides of the sliding plate 111, and the buffer plate 17 is connected with the sliding plate 111 through a compression spring 171. The buffer pad 161 is arranged to facilitate the sliding plate 111 to reduce the collision with the cylinder body of the rodless cylinder 12 when moving to the left and right ends of the rodless cylinder 12, the buffer plate 17 directly collides with the buffer pad 161, so that the compression spring 171 is compressed, thereby reducing the collision force applied to the sliding plate 111, and the compression spring 171 is arranged to facilitate the sliding plate 111 to move the buffer plate 17.

[0032] As Figure 1 and Figure 4The length of the sliding block 121 on the height position higher non-rod air cylinder 12 is shorter than the length of the sliding block 121 on the height position lower non-rod air cylinder 12, the width of the cross plate gradually decreases away from the end of the machine body 1, the purpose is to make the cross plate and the machine body 1 slip connection position strength increase, the length of the sliding plate 111 is distributed along the length direction of the sliding block 121 of the non-rod air cylinder 12, the sliding plate 111 is connected with the sliding block 121 through several locking bolts 18, at this time, increasing the length of the sliding plate 111 and the sliding block 121 makes the stability of the cross beam 11 after being fixed increase.

[0033] Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalent technologies, the present application also intends to include these modifications and variations.
