[0029] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0030] It is understandable that, referring to Figures 1 to 6 The embodiment of the first aspect of the utility model proposes a rotating workbench, including a rotating seat 100, a screen assembly 200 and a support assembly 300, which are usually driven to rotate by a servo motor to accurately control the rotation angle. A bearing platform 110 is provided on both sides of the rotating seat 100, and the bearing platform 110 can be installed with a fixture, and a workpiece is installed on the fixture to position the workpiece for laser cutting. A slide 400 can also be provided on the bearing platform 110, and the slide 400 can move in a direction away from or close to the rotating seat 100, so as to adjust the position of the workpiece, and improve the accuracy and efficiency of laser cutting during the processing. The rotating workbench drives the two bearing platforms 110 to rotate through the rotating seat 100, and the loading and unloading of the workpiece can be realized by rotating 180°. Considering the processing requirements of some workpieces, the position of the workpiece can be adjusted by using the slide 400.

[0031] The screen assembly 200 is connected to the rotating seat 100. The screen assembly 200 is arranged vertically. The function of the screen assembly 200 is to close the entrance and exit of the laser cutting machine. Since strong light will be generated during the laser cutting process, the screen assembly 200 is a square tube frame with a metal plate. The screen assembly 200 rotates with the rotating seat 100. When it rotates 180°, the screen assembly 200 changes direction and still keeps the entrance and exit of the laser cutting machine closed.

[0032] The support assembly 300 corresponds one-to-one to the bearing platform 110. The support assembly 300 includes a base 310 and a telescopic component 320. The base 310 is an installation foundation and can be installed on the ground or on a rack or other equipment. The telescopic component 320 is fixed to the upper end of the base 310. The telescopic component 320 can be made of a cylinder, an oil cylinder, an electric push rod, etc., as long as it can meet the telescopic and support requirements. A ball head support 330 is provided at the upper end of the telescopic component 320, and a support plate 120 is provided on the bottom surface of the bearing platform 110. The support plate 120 is located at one end of the bearing platform 110 away from the rotating seat 100. The support plate 120 is provided with a spherical groove 121, and the diameter of the spherical groove 121 is larger than the diameter of the ball head support 330.

[0033] When the rotary worktable is in operation and rotates to the right position, the telescopic component 320 of the support assembly 300 moves, and the ball head support 330 rises into the spherical groove 121 and contacts the support plate 120, thereby supporting the carrying platform 110, avoiding deformation of the carrying platform 110 due to the cantilever structure, preventing the rotating worktable from changing the positioning of the workpiece, and helping to improve processing accuracy.

[0034] It can be understood that in some embodiments of the first aspect of the utility model, the telescopic component 320 is a cylinder, the ball head support 330 is fixed to the end of the piston rod of the cylinder, and the ball head support 330 is connected to the upper shield 340, which surrounds the cylinder. The upper shield 340 can be used to protect the cylinder, prevent sparks, smoke and waste generated by laser cutting from contacting the cylinder, and improve the operating reliability and service life of the cylinder.

[0035] Reference Figure 4 and Figure 5 It is understandable that, considering that the ball head support 330 rises and falls under the drive of the cylinder, the upper shield 340 follows the rise and fall of the ball head support 330, and a protective gap will appear. A lower shield 350 is provided on the base 310. The lower shield 350 also surrounds the cylinder, and the upper shield 340 is inserted into the lower shield 350. When the upper shield 340 follows the ball head support 330 to rise, the upper shield 340 and the lower shield 350 remain in an inserted state to fully protect the cylinder. In order to facilitate the connection of the cylinder to the air pipe, wiring grooves are provided on the upper shield 340 and the lower shield 350 to facilitate the installation of the air pipe joint.

[0036] For ease of installation, a cylinder is provided at the upper end of the upper shield 340. The cylinder is distributed on the periphery of the ball head support 330 and is fixed to the ball head support 330 by fasteners. The fasteners can be screws. The cylinder can be replaced and maintained conveniently by loosening the screws.

[0037] It can be understood that in order to position and install the cylinder, a positioning groove is provided at the upper end of the base 310, the lower end of the cylinder is located in the positioning groove, and a notch is provided on one side wall of the positioning groove, which extends to the outer wall of the base 310. The notch can facilitate the installation of the air pipe joint and is easy to operate.

[0038] Reference Figure 6 In some embodiments of the first aspect of the utility model, the support plate 120 is provided with a plurality of through holes, and the plurality of through holes are evenly distributed circumferentially around the spherical groove 121. Bolts 122 are passed through the through holes to fix the support plate 120 to the supporting platform 110. The diameter of the through hole is larger than the diameter of the bolt 122. During installation, the position of the support plate 120 can be fine-tuned by utilizing the gap between the inside of the through hole and the bolt 122, so that the ball head support 330 and the spherical groove 121 are aligned, thereby improving the stability of the support.

[0039] It is understandable that the shapes of the ball head support 330 and the spherical groove 121 can be consistent, or the diameter of the spherical groove 121 can be larger than the ball head support 330 to facilitate the ball head support 330 to enter the spherical groove 121.

[0040] Reference Figure 6 Alternatively, the bottom surface of the carrying platform 110 may be provided with a plurality of adjustment blocks 130, the plurality of adjustment blocks 130 surround the support plate 120, and the adjustment blocks 130 are connected with an adjustment rod 131, and the adjustment rod 131 can abut against the support plate 120 to fine-tune the support plate 120. For example, the adjustment rod 131 is a screw rod, and the support plate 120 can be pushed by rotating the adjustment rod 131, thereby fine-tuning the spherical groove 121. Of course, the adjustment rod 131 can also adopt other structures, such as an electric push rod, to achieve electric adjustment.

[0041] Reference Figure 3 The carrying platform 110 includes a main crossbar 111 fixed to the rotating seat 100, the two ends of the main crossbar 111 are fixedly connected to the main longitudinal bars 112, the other ends of the two main longitudinal bars 112 are fixedly connected to the secondary crossbars 113, and the centers of the main crossbar 111 and the secondary crossbar 113 are also provided with connecting rods 114, and the support plate 120 is located at the connection between the connecting rod 114 and the secondary crossbar 113, so that the support plate 120 is at the farthest point of the cantilever of the carrying platform 110, and the support assembly 300 has the best supporting effect on the carrying platform 110. The support plate 120 can be connected to the bottom surface of the connecting rod 114, can also be connected to the bottom surface of the secondary crossbar 113, and can also be connected to the bottom surfaces of the connecting rod 114 and the secondary crossbar 113 at the same time.

[0042] It can be understood that the supporting platform 110 is provided with two loading plates 115, and the two loading plates 115 are arranged on opposite sides of the two main longitudinal rods 112. The main longitudinal rods 112 and the loading plates 115 are connected and fixed by multiple support plates. The structure is stable and reliable. A slide rail 116 is provided on the loading plate 115, and the slide rail 116 is connected to the slide 400 to guide the movement of the slide 400 and support the slide 400.

[0043] The embodiment of the second aspect of the utility model proposes a laser cutting machine, including a rotating worktable of the embodiment of the first aspect, including all technical solutions of the rotating worktable, and having all technical effects of the rotating worktable, which will not be repeated.
