[0033] See also Figure 1 The workbench device provided in the present application includes a frame 10, a positioning assembly 20 and a first workbench 30. The first workbench 30 is slidably arranged on the frame 10, and the first workbench 30 is provided with a first positioning hole. Figure 2 and Figure 3 The positioning assembly 20 includes a first driving member 21 and a first positioning member 22 . The first driving member 21 is disposed on the frame 10 , and the first positioning member 22 is disposed at the driving end of the first driving member 21 .

[0034] The first workbench 30 is used to carry the workpiece and to move the workpiece from the loading area to the processing area or from the processing area to the loading area by sliding on the frame 10. When the first workbench 30 moves to the preset position, the first driving member 21 drives the first positioning member 22 to move, so that the first positioning member 22 enters the first positioning hole of the first workbench 30.

[0035] At this time, the first positioning member 22 abuts against the wall of the first positioning hole, so that the first positioning member 22 limits the first workbench 30, so that the first workbench 30 will not shake after moving to the preset position.

[0036] See also Figure 4 and Figure 5 In some embodiments, the first workbench 30 is connected to a first fixing block 31 , and a first positioning hole 311 is formed on the first fixing block 31 .

[0037] The first fixing block 31 may be disposed at an end of the first workbench 30 and protrude from the first workbench 30 , so as to cooperate with the first positioning member 22 , thereby achieving positioning of the first workbench 30 .

[0038] In some embodiments, a first positioning surface 221 is provided at the end of the first positioning member 22, and a second positioning surface 3111 is provided in the first positioning hole 311. The first driving member 21 is used to drive the first positioning member 22 into the first positioning hole 311 and make the first positioning surface 221 and the second positioning surface 3111 abut against each other.

[0039] After the first positioning surface 221 and the second positioning surface 3111 abut against each other, the relative position of the first positioning member 22 and the first positioning hole 311 can be determined, so that after each positioning is completed, the first fixing block 31 and the first workbench 30 are fixed at the same position.

[0040] Further, the first positioning surface 221 and the second positioning surface 3111 are both configured as inclined surfaces, or the first positioning surface 221 and the second positioning surface 3111 are both configured as arc surfaces.

[0041] After being set as an inclined surface or an arc surface, it can not only determine the relative position of the first positioning member 22 and the first positioning hole 311, but also play a guiding role. Even if the stop position of the first workbench 30 deviates from the preset position, the first positioning member 22 can be guided to smoothly enter the first positioning hole 311.

[0042] In a specific embodiment, the first positioning member 22 can be a cylinder, and the first positioning surface 221 and the second positioning surface 3111 are both conical surfaces. The two conical surfaces fit together to achieve positioning, which not only has high positioning stability but also can ensure positioning accuracy and consistency during multiple positioning processes.

[0043] In addition, an adjustment space can be reserved for the first positioning hole 311 in a direction perpendicular to the moving direction of the first workbench 30. For example, the first positioning hole 311 can be set as a waist-shaped hole. When the first workbench 30 moves forward and backward, if its left and right positions deviate, the first positioning member 22 can also smoothly enter the first positioning hole 311 to reduce the requirements for the movement accuracy of the first workbench 30.

[0044] In some embodiments, the first driving member 21 is used to drive the first positioning member 22 to move in a direction perpendicular to the surface of the first workbench 30 , so that the first positioning surface 221 and the second positioning surface 3111 abut against each other, and the first workbench 30 is lifted by the first positioning member 22 .

[0045] When the first positioning member 22 lifts up the first workbench 30 through the first fixing block 31, due to the influence of gravity, the first fixing block 31 applies pressure to the second positioning surface 3111 of the first positioning member 22 through the first positioning surface 221, and at the same time increases the friction between the first positioning surface 221 and the second positioning surface 3111. After the first workbench 30 is lifted up, relative sliding between the first positioning surface 221 and the second positioning surface 3111 can be avoided, thereby preventing the first workbench 30 from shaking.

[0046] Furthermore, when the first workbench 30 carries a workpiece, if the workpiece is heavy, such as a large thick plate, the first workbench 30 may fall, and the surface of the thick plate cannot be kept level. The first positioning member 22 can lift the first workbench 30 through the first fixing block 31 until its surface is in a horizontal state, thereby improving the subsequent processing accuracy.

[0047] It is understandable that the first positioning hole 311 on the first workbench 30 or the first fixing block 31 can be replaced by a first positioning groove, and the first positioning member 22 can limit the first fixing block 31 by abutting against the groove wall of the first positioning groove. In addition, a second positioning surface can be provided in the first positioning groove, and can cooperate with the first positioning surface 221 to achieve positioning and guiding functions.

[0048] In some embodiments, the workbench device further includes a second workbench 40 , which is slidably disposed on the frame 10 , and the first workbench 30 and the second workbench 40 are located at different heights of the frame 10 .

[0049] The first working table 30 and the second working table 40 can work alternately. Figure 1 When the workpiece carried by the first workbench 30 is processed in the processing area, the second workbench 40 moves to the loading area to load the workpiece; please refer to Figure 6 After the workpiece carried by the first workbench 30 is processed, the first workbench 30 moves to the loading area to load the workpiece, and the second workbench 40 that has completed loading moves to the processing area to achieve the purpose of alternating processing.

[0050] The second workbench 40 is provided with a second positioning hole. The positioning assembly 20 further includes a second driving member 23 and a second positioning member 24 . The second driving member 23 is disposed on the frame 10 , and the second positioning member 24 is disposed at the driving end of the second driving member 23 .

[0051] When the second workbench 40 moves to the preset position, the second driving member 23 drives the second positioning member 24 to move, so that the second positioning member 24 enters the second positioning hole. At this time, the second positioning member 24 abuts against the hole wall of the second positioning hole, so that the second positioning member 24 limits the second fixing block 41. After limiting the movement of the second fixing block 41, the movement of the second workbench 40 connected to the second fixing block 41 can be further limited, so that the second workbench 40 is not prone to shaking.

[0052] In some embodiments, the second workbench 40 is connected to a second fixing block 41 , and a second positioning hole 411 is formed on the second fixing block 41 .

[0053] The second fixing block 41 may be disposed at an end of the second workbench 40 and protrude from the second workbench 40 , so as to cooperate with the second positioning member 24 , thereby achieving positioning of the second workbench 40 .

[0054] The second fixing block 41 can adopt the same or similar structure as the first fixing block 31, and the second positioning member 24 can adopt the same or similar structure as the first positioning member 22. For example, the end of the second positioning member 24 is provided with a third positioning surface, and the second positioning hole 411 is provided with a fourth positioning surface. The second driving member 23 can drive the second positioning member 24 into the second positioning hole 411, and make the third positioning surface and the fourth positioning surface abut against each other. In addition, the first positioning surface 221 and the second positioning surface 3111 are both set as inclined surfaces, or the first positioning surface 221 and the second positioning surface 3111 are both set as arc surfaces.

[0055] Furthermore, the second positioning hole 411 on the second fixing block 41 can be replaced by a second positioning groove, and the second positioning member 24 can limit the second fixing block 41 by abutting against the groove wall of the second positioning groove.

[0056] In some embodiments, see Figure 2 and Figure 3 The positioning assembly 20 also includes a first mounting seat 25, a second mounting seat 26 and a support plate 27. The second mounting seat 26 is arranged on the frame 10. The first mounting seat 25 is connected to the second mounting seat 26 through the support plate 27, and the first mounting seat 25 and the second mounting seat 26 are located at different heights of the frame 10. The first driving member 21 is arranged on the first mounting seat 25, and the second driving member 23 is arranged on the second mounting seat 26.

[0057] The support plate 27 plays a role of connection and support. When the first workbench 30 is arranged above the second workbench 40, the heights of the first positioning member 22 and the first fixing block 31 can be made to correspond, so that the first positioning member 22 and the first fixing block 31 can be matched. At the same time, by setting the support plate 27, the first mounting seat 25 is arranged above the second mounting seat 26, so that the heights of the second positioning member 24 and the second fixing block 41 correspond, and the second positioning member 24 and the second fixing block 41 can be matched.

[0058] Specifically, the number of the support plates 27 can be two, which are disposed at both ends of the first mounting seat 25 and are integrally formed with the first mounting seat 25 . The second positioning member 24 is disposed between the two support plates 27 .

[0059] Due to the presence of the first fixing block 31 and the second fixing block 41, the overall volume of the positioning assembly 20 can be made smaller. During the positioning process, the first fixing block 31 can move to the top of the first mounting seat 25 and cooperate with the first positioning member 22; the second fixing block 41 can move to the top of the second mounting seat 26 and enter between the two support plates 27 to cooperate with the second positioning member 24.

[0060] The first driving member 21 and the second driving member 23 may adopt thin cylinders, which have the advantages of compact structure, light weight, small space occupation, etc. In addition, in order to save space and reduce the overall volume of the positioning assembly 20, the first driving member 21 may be arranged below the first mounting seat 25, and its piston rod passes through the first mounting seat 25 and is connected to the first positioning member 22; the second driving member 23 may be arranged below the second mounting seat 26, and its piston rod passes through the second mounting seat 26 and is connected to the second positioning member 24.

[0061] Of course, the first driving member 21 and the second driving member 23 can also be driven by other methods such as a hydraulic cylinder, a motor combined with a gear rack, etc., and this application does not limit this.

[0062] In some embodiments, the positioning assembly 20 also includes a first guide member 28 and a second guide member 29, the first guide member 28 is disposed on the first mounting seat 25, the first positioning member 22 is slidably connected to the first guide member 28, the second guide member 29 is disposed on the second mounting seat 26, and the second positioning member 24 is slidably connected to the second guide member 29.

[0063] The first guide member 28 is used to guide the movement of the first positioning member 22. For example, the first guide member 28 can be a sleeve, the first positioning member 22 is inserted into the sleeve, and the first driving member 21 drives the first positioning member 22 to slide in the sleeve. Alternatively, the first guide member 28 can also be guided by other methods such as positioning columns and guide rails. The second guide member 29 can be guided in the same way as the first guide member 28.

[0064] In addition, the positioning assembly 20 may also include a first sensor and a second sensor, the first sensor being disposed on the first mounting seat 25 or the first driving member 21 to sense the first fixed block 31 after being in place, and the second sensor being disposed on the second mounting seat 26 or the second driving member 23 to sense the second fixed block 41 after being in place.

[0065] In some embodiments, the number of positioning components 20 is two or more, the moving direction of the first workbench 30 is defined as the first direction, the second direction is perpendicular to the first direction, and the number of positioning components 20 is two or more, which are arranged on the frame 10 at the same height along the second direction.

[0066] For example, there are two positioning assemblies 20, which are respectively arranged on both sides of the end of the frame 10 to increase the stability of the first workbench 30 and the second workbench 40 when positioning. If the size of the first workbench 30 and the second workbench 40 is required to be larger, the number of positioning assemblies 20 can be further increased to achieve a stable processing effect.

[0067] In addition, the present application also provides a laser cutting machine, comprising the above-mentioned workbench device, which is used to carry the workpiece to be cut. The laser cutting machine also includes a laser cutting device, which is used to cut the workpiece carried by the workbench device.

[0068] See also Figure 1-Figure 7 In the specific process, the laser cutting machine performs the following cutting steps:

[0069] After the first workbench 30 reaches the designated cutting position, the first driving member 21 (using a cylinder) in the two sets of fixed components is in a working state, and the first positioning member 22 moves upward along with the piston rod of the first driving member 21, so that the first positioning member 22 enters the first positioning hole 311 or the first positioning groove, completing the positioning of the first workbench 30, and allowing the laser cutting device to cut the plate carried by the first workbench 30.

[0070] During the exchange process of the first workbench 30 and the second workbench 40, the cylinder is always in a retracted state, so that an appropriate gap is left between the first positioning member 22 and the first workbench 30, and between the second positioning member 24 and the second workbench 40, to ensure that there will be no scratches, pauses, etc. caused by interference between the positioning members and the workbench when the first workbench 30 and the second workbench 40 are frequently exchanged, thereby improving the reliability of the equipment.

[0071] After the second workbench 40 reaches the designated cutting position, the second driving member 23 (using a cylinder) in the two sets of fixed components is in working state, and the second positioning member 24 moves upward along with the piston rod of the second driving member 23, so that the second positioning member 24 enters the second positioning hole 411 or the second positioning groove, completing the positioning of the second workbench 40, and allowing the laser cutting device to cut the plate carried by the first workbench 40.

[0072] It is understandable that those skilled in the art can make equivalent substitutions or changes based on the technical solution and application concept of the present application, and all these changes or substitutions should fall within the protection scope of the claims attached to the present application.
