[0030] See also Figure 1-2 As shown, a workpiece placement rack for a CNC machine tool includes a placement portion 1 for placing a pallet and a loading portion 2 arranged on one side of the placement portion 1; during operation, the workpiece is loaded on the pallet and then placed in the loading portion 2, and the pallet is transported into the placement portion 1 through the loading portion 2.

[0031] See also Figure 3As shown, the placement portion 1 includes a placement rack 11, and a four-layer support module 12 is arranged in the upper half of the placement rack 11. The trays are stacked and placed in the placement rack 11 through the support module 12. Of course, the number of groups of the support modules 12 is only one embodiment, and is not intended to limit the scope of the present application. More or less can be arranged as long as the requirements are met; a lifting module 13 is arranged in the lower half of the placement rack 11. During operation, when the first group of trays are transported into the placement portion 1, the lifting module 13 lifts the first group of trays. , placed on the support module 12 of the lowest layer and then reset. After the second group of pallets are transported into the placement portion 1, the lifting module 13 lifts the second group of pallets, and during the lifting process, the second group of pallets lift the first group of pallets and move upward at the same time, so that the second group of pallets are placed on the support module 12 of the lowest layer. At this time, the first group of pallets are placed on the support module 12 above the lowest layer; the same operation is performed until pallets are placed in all the support modules 12 and the loading is completed; thereby, the pallets are placed in the support module 12 through the lifting module 13.

[0032] Among them, see Figure 4 As shown, each layer of the support module 12 includes a pair of support components 121 for supporting both sides of the tray; each group of the support components 121 includes a connecting rod 1211, three groups of support blocks 1212 sleeved on the connecting rod 1211 and rotatable on the connecting rod 1211, and a limiting rod 1213 for limiting the support blocks 1212; during installation, after the support blocks 1212 are sleeved on the connecting rod 1211, the connecting rod 1211 and the limiting rod 1213 are both set on the placement rack 11, see the details. Figure 3 As shown, at this time, in the absence of external force, the support block 1212 is in a horizontal state; during operation, the support block 1212 can rotate on the connecting rod 1211 under the push of the tray, and when the tray is completely separated from the support block 1212, the support block 1212 is reset to a horizontal state under the action of gravity, and the tray moves down with the lifting module 13 and is placed on the support block 1212 when the lifting module 13 shrinks and resets; it should be noted that the number of support blocks 1212 set in each group of the support assembly 121 is not limited to three groups, and when setting, the set number can be any number as long as it can meet the use requirements.

[0033] In addition, in this embodiment, the lifting module 13 is a scissor-type lifting mechanism. Of course, the above is only one implementation method and is not intended to limit the scope of the present application. When setting, other lifting mechanisms may also be used, such as: cylinders, etc.

[0034] See also Figure 5As shown, the loading part 2 includes a loading rack 21, and a pushing module 22 is provided on the loading rack 21. During operation, when a pallet loaded with workpieces is placed in the loading part 2, the pallet is pushed from the loading part 2 to the placement part 1 through the pushing module 22.

[0035] Among them, continue to see Figure 5 As shown, the pushing module 22 includes a rodless cylinder 221 and a push plate 222 arranged on the slider of the rodless cylinder 221; during operation, the push plate 222 is driven to move back and forth by the slide of the rodless cylinder 221, thereby pushing the tray.

[0036] For further information, see Figure 1 As shown, the placing portion 1 and the loading portion 2 are also provided with a pair of roller modules 3 respectively; and in this embodiment, see Figure 6 As shown, the roller module 3 includes a U-shaped frame 31, and a row of rotatable rollers 32 are arranged in the U-shaped frame 31, and parts of the rollers 32 protrude from the openings of the U-shaped frame 31; during operation, under the push of the pushing module 22, the tray slides from the loading part 2 into the placement part 1 along the rollers 32, which effectively reduces the friction between the tray and the loading part 2 and the placement part 1 during the conveying process.

[0037] For further information, see Figure 3 and Figure 5 As shown, the placement rack 11 is provided with a first positioning hole 111, and the loading rack 21 is provided with a second positioning hole 211 adapted to the first positioning hole 111. When connected, refer to Figure 2 and Figure 7 As shown, by passing a positioning bolt 4 through the first positioning hole 111 and the second positioning hole 211 matched thereto, the connection position between the placement rack 11 and the loading rack 21 is locked and limited, thereby ensuring the accuracy of the connection between the placement portion 1 and the loading portion 2 while preventing displacement between the two. In the present embodiment, two groups of the first positioning holes 111 and the second positioning holes 211 are provided. It should be noted that, through the above-mentioned setting method, a single group of the loading portion 2 can be adapted to multiple groups of the placement portions 1, which can effectively reduce costs.

[0038] For further information, see Figure 1-3 As shown, two groups of photoelectric sensors 5 are arranged on the placement rack 11; one group is used to monitor whether a pallet is transported into the placement portion 1; and the other group is used to monitor whether there is a pallet in the uppermost support module 12.

[0039] Further, see Figure Figure 1-2 and Figure 5As shown, a universal wheel 6 is respectively provided at the four top corners of the lower end of the loading rack 21 to facilitate the movement of the loading rack 21.

[0040] For further information, see Figure 1-2 As shown, the placement rack also includes a control system 7, and the control system 7 is arranged on the loading rack 21; when connected, the lifting module 13, the pushing module 22 and the opposing photoelectric sensor 5 are electrically connected to the control system 7.

[0041] The working principle of the utility model is as follows:

[0042] Before use, first push the loading part 2 to the front or rear of the placing part 1, align the first positioning hole 111 and the matching second positioning hole 211, insert the positioning pin 4 to connect the two together; then connect the lifting module 13, the pushing module 22 and the opposing photoelectric sensor 5 to the control system 7.

[0043] During operation, the processed workpiece is placed on the pallet and then placed in the loading part 2; the pushing module 22 is started by the control system 7, and the pallet slides into the placement part 1 along the roller module 3 under the push of the pushing module 22. At this time, the photoelectric sensor 5 used to monitor whether there is a pallet transported into the placement part 1 detects that a pallet has entered, and feeds back a signal to the control system 5. The control system 5 controls the lifting module 13 to start, lifts the pallet and places it in the supporting module 12, and resets it after loading is completed, and performs the next group of loading, which is consistent with the above and will not be repeated here until the loading is completed.

[0044] It should be noted that when the photoelectric sensor 5 used to monitor whether there is a pallet in the topmost support module 12 detects that there is a pallet in the topmost support module 12, it feeds back a signal to the control system 5, and the control system 5 controls the pushing module 22 to no longer push the pallet into the placement section 1; then the loading section 2 is connected to another group of placement sections 1 to continue loading.

[0045] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
