The utility model will be further described in combination with the drawings and embodiments:

[0030] The mounting frame 1 is fixedly arranged on the table surface of the numerical control five-axis machining center (the numerical control five-axis machining center is not shown in the figure);

[0031] The telescopic piece 2 is fixedly arranged on the mounting frame 1, and the telescopic piece 2 is connected with the internally hollow placement box 3 (the optimization of the scheme, one side of the placement box 3 is provided with a sealing door to facilitate the maintenance of the internal parts);

[0032] A plurality of adsorption holes 4 are formed in the top of the placement box 3, and the adsorption holes 4 are in communication with the vacuum adsorption assembly 5 fixedly arranged in the placement box 3;

[0033] The placement plate 6 is fixed on the mounting frame 1 and has through holes 7 that are the same size as the placement box 3 and are directly opposite each other.

[0034] The limiting plate 8 is set on the placement plate 6 and the limiting plate 8 and the through hole 7 are distributed at intervals;

[0035] The clamping components are fixed on the mounting frame 1 and are symmetrically distributed about the telescopic component 2.

[0036] Further refinements of the embodiments of this utility model, such as... Figure 1 As shown, the clamping assembly includes a cylinder 12 and a clamping plate 13. The cylinder 12 is symmetrically arranged on the mounting frame 1, and the cylinder 12 is connected to the clamping plates 13 that are distributed opposite each other and spaced apart from the limiting plate 8.

[0037] A further refinement of the above embodiment is that a rubber layer is provided on the clamping plate 13, as described in the appendix to the instruction manual. Figure 1 It is shown but not labeled.

[0038] Further refinements of the embodiments of this utility model, such as... Figure 1 As shown, the vacuum adsorption assembly 5 includes a vacuum pump 14 and a suction box 15. The vacuum pump 14 is fixed inside the placement box 3. The input end of the vacuum pump 14 is connected to the suction box 15 fixed inside the placement box 3. The suction box 15 has a plurality of suction holes that correspond one-to-one with and are connected to the adsorption holes 4. The output end of the vacuum pump 14 is connected to the outside through an output pipe.

[0039] In a further optimization of the above embodiment, a filter screen is provided at the end of the output pipe. The suction hole and the filter screen are not shown in the figure. The filter screen can prevent debris and other impurities from entering.

[0040] It should be noted that the telescopic component 2, cylinder 12 and vacuum pump 14 are all electrically connected to the controller, which is specifically installed on the CNC five-axis machining center and is not shown in the figure.

[0041] The working process of this utility model is as follows:

[0042] Initially, the telescopic component 2 is operated by the controller to make the upper surface of the placement box 3 and the upper surface of the placement plate 6 level. Then, the pre-sanded rectangular wooden board is placed on the placement plate 6 and the placement box 3. It should be noted that the size of the placement box 3 is smaller than the size of the wooden board to be processed (both length and width are smaller). The function of the placement plate 6 is to stably support the rectangular wooden board.

[0043] The long side end surface of the wood board is in contact with the limiting plate 8 during the placing process to limit the front and back positions of the wood board. After the contact is completed, the controller controls the cylinder 12 to operate and then the horizontal position of the wood board is limited by the clamping plate 13. When the front, back, left and right positions of the wood board are all limited, the controller controls the vacuum suction assembly 5 to work, and then the wood board can be firmly suctioned on the placing box 3 through the suction holes 4 (at this time, the suction holes 4 are completely covered by the wood board). After the suction is completed, the clamping plate 13 moves away from the wood board under the action of the cylinder 12;

[0044] Then the controller controls the telescopic part 2 to move and drive the wood board to rise. The purpose of rising is to avoid the blocking of the clamping assembly and the limiting plate 8 in the subsequent numerical control machining process. When the wood board rises to the pre-set height, the program can be started to begin numerical control machining. The numerical control five-axis machining center is prior art, and its working principle is not described. The machining program is input in advance, and the subsequent complex machining process of the surface of the rectangular wood board can be automatically and accurately completed.

[0045] When the wood board is machined, the controller controls the telescopic part 2 to operate, and then the wood board can be in contact with the placing plate 6 again. After the debris attached to the surface of the wood board and the tooling is cleaned, the controller controls the vacuum suction assembly 5 to release the suction of the wood board. Then the wood board is taken down, and the above process is repeated to start a new round of numerical control machining process of the rectangular wood board.

[0046] Compared with the prior art, the device can accurately limit the placing position of the wood board on the placing box 3 through the limiting plate 8 and the clamping assembly. Then the wood board can be firmly suctioned on the placing box 3 by starting the vacuum suction assembly 5. Then the telescopic part 2 drives the wood board to rise to the pre-set height and cooperates with the numerical control five-axis machining center to perform numerical control machining. The clamping assembly and the limiting plate 8 do not hinder the machining during the machining of the numerical control five-axis machining center. The positioning effect of the tooling is good, and the machining effect of the numerical control five-axis machining center on the rectangular wood board is further improved.

[0047] In some embodiments, as Figure 2As shown, the placing plate 6 is provided with an electric push rod 9 and symmetrically distributed sliding grooves 10, the two ends of the limiting plate 8 are symmetrically provided with mounting rods 11 in sliding fit with the sliding grooves 10, and the limiting plate 8 is connected with the electric push rod 9, and the electric push rod 9 is electrically connected with the controller; before the wood plate of a larger size needs to be replaced for numerical control machining, the controller is first used to control the operation of the electric push rod 9, so that the orientation of the limiting plate 8 can be changed, and it should be noted that the positions of the limiting plates 8 corresponding to wood plates of different sizes are previously set in the controller, and only the corresponding wood plate size button needs to be selected on the controller to automatically complete the position adjustment of the limiting plate 8 (wood plates of different sizes are all standard parts), and then the placing area of the large-size wood plate on the placing box 3 can be accurately limited by the limiting plate 8 and the clamping assembly to ensure the effect of subsequent vacuum adsorption.

[0048] In other embodiments, the mounting frame 1 is provided with a blowing pipe higher than the placing plate 6, the blowing pipe is communicated with a gas pump, and a plurality of downward inclined branch pipes are arranged on the blowing pipe, the gas pump is communicated with a gas source, and the gas pump is electrically connected with the controller; after the numerical control machining is completed, the gas pump is started to inject clean gas into the blowing pipe, and then the debris attached to the workpiece is automatically blown off from the surface, and then the remaining debris on the surface of the wood plate is cleaned when the placing box 3 moves to the height level with the placing plate 6, and then the vacuum adsorption is released after the debris is completely cleaned, so that the debris on the surface of the workpiece and the wood plate can be automatically removed.

[0049] The basic principle, main features and advantages of the present application are shown and described above. It should be understood by those skilled in the art that the present application is not limited by the above embodiments, and the above embodiments and descriptions in the specification are only to illustrate the principle of the present application, and various changes and improvements can be made to the present application without departing from the spirit and scope of the present application, and these changes and improvements all fall within the scope of the present application.
