[0031] Embodiment 2

[0032] Based on Embodiment 1, it further includes:

[0033] As Figure 7As shown, the feeding device 06 includes a plurality of brackets four 61, bracket five 62, two brackets six 63, two groups of brackets seven 64, bracket eight 65, cylinder two 66 and ejector block 67. The plurality of brackets four 61 are respectively installed at the front and rear ends of bracket five 62. Bracket five 62 is installed at the right end of the workbench surface 12, and the top end of bracket five 62 is aligned with the bottom end of the feeding groove of the workbench surface 12. A chute longer than the length of the heat dissipation plate is provided at the left part of bracket five 62, and the width of the chute is smaller than the width of the feeding groove of the workbench surface 12. The two brackets six 63 are both installed at the top end of bracket five 62, and the two brackets six 63 are respectively aligned with the front and rear ends of the feeding groove of the workbench surface 12. The two groups of brackets seven 64 are respectively installed at the top ends of the two brackets six 63. Bracket eight 65 is installed on two brackets seven 64 of different groups at the rightmost side. Cylinder two 66 is installed at the bottom end of the right part of bracket five 62. The ejector block 67 is installed at the front end of cylinder two 66, and the ejector block 67 is slidably matched with the chute. The top end of the ejector block 67 is provided with a top plate longer than the heat dissipation plate;

[0034] First, stack the heat dissipation plates between the two groups of brackets six 63. Then, turn on cylinder two 66. Cylinder two 66 provides power to drive the ejector block 67 to move left and right. When the ejector block 67 moves left, it pushes the heat dissipation plate for feeding. During feeding, the top plate prevents the stacked heat dissipation plates from falling, preventing material jamming. When the ejector block 67 moves right, it vacates the position, allowing the new unthreaded heat dissipation plate to reach the pre-feeding position under the action of gravity. After that, turn on cylinder one 21. Cylinder one 21 provides power, and the pressing plate 22 moves down to clamp the heat dissipation plate. Then, turn on the linear motor 31. The linear motor 31 provides power to drive the bracket two 34 to move left and right. The bracket two 34 drives the telescopic electric main shaft 41 and the tap 42 to move left and right to adjust the tapping position. After determining the tapping position, turn on the telescopic electric main shaft 41. The telescopic electric main shaft 41 provides power, and the tap 42 rotates and moves down to tap the heat dissipation plate. Part of the waste chips generated during tapping fall onto the filter plate 53 through the tapping groove, and the other part accumulates on the surface of the heat dissipation plate. After one heat dissipation plate is processed, turn on cylinder two 66. Cylinder two 66 provides power to drive the ejector block 67 to move left and right. When the ejector block 67 moves left, it pushes the heat dissipation plate for feeding, and at the same time, the processed heat dissipation plate is ejected to complete the discharging. During feeding, the top plate prevents the stacked heat dissipation plates from falling, preventing material jamming. When the ejector block 67 moves right, it vacates the position, allowing the new unthreaded heat dissipation plate to reach the pre-feeding position under the action of gravity. When the heat dissipation plate is pushed for discharging, the waste chips on its surface move along with it and leave the heat dissipation plate under the blockage of the pressing plate 22, and fall onto the filter plate 53 through the tapping groove and the material guiding groove. The filter plate 53 filters the waste chips containing tapping fluid, so that the waste chips are intercepted at the top end of the filter plate 53, and the tapping fluid enters the inside of the liquid storage tank 11 for storage. When it is necessary to discharge the waste chips, the filter plate 53 blocks and drives the waste chips to leave the machine. The handle 54 facilitates pulling the filter plate 53, and the rubber plug 51 seals the liquid storage tank 11, facilitating the storage of the used tapping fluid.

[0035] AsFigures 1 to 7 As shown in the figure, a bench tapping machine for processing the threaded holes of a heat sink of the present utility model, when working, first stacks the heat dissipation plates between two sets of brackets six 63, and then turns on the second cylinder 66. The second cylinder 66 provides power to drive the ejector block 67 to move left and right. When the ejector block 67 moves left, it pushes the heat dissipation plate for feeding. When feeding, the top plate prevents the stacked heat dissipation plates from falling, preventing material jamming. When the ejector block 67 moves right, it gives way, so that the new unthreaded heat dissipation plate reaches the pre-feeding position under the action of gravity. Then turn on the first cylinder 21. The first cylinder 21 provides power, and the pressure plate 22 moves down to clamp the heat dissipation plate. Then turn on the linear motor 31. The linear motor 31 provides power to drive the second bracket 34 to move left and right. The second bracket 34 drives the telescopic electric main shaft 41 and the tap 42 to move left and right to adjust the tapping position. After determining the tapping position, turn on the telescopic electric main shaft 41. The telescopic electric main shaft 41 provides power, and the tap 42 rotates and moves down to tap the heat dissipation plate. Part of the waste chips generated during tapping fall onto the filter plate 53 through the tapping groove, and the other part accumulates on the surface of the heat dissipation plate. After a heat dissipation plate is processed, turn on the second cylinder 66. The second cylinder 66 provides power to drive the ejector block 67 to move left and right. When the ejector block 67 moves left, it pushes the heat dissipation plate for feeding, and at the same time, the processed heat dissipation plate is ejected to complete the discharging. When feeding, the top plate prevents the stacked heat dissipation plates from falling, preventing material jamming. When the ejector block 67 moves right, it gives way, so that the new unthreaded heat dissipation plate reaches the pre-feeding position under the action of gravity. When the heat dissipation plate is pushed for discharging, the waste chips on its surface move along with it and leave the heat dissipation plate under the block of the pressure plate 22, and fall onto the filter plate 53 through the tapping groove and the material guiding groove. The filter plate 53 filters the waste chips containing the tapping liquid, so that the waste chips are intercepted at the top of the filter plate 53, and the tapping liquid enters the internal storage of the liquid storage tank 11. When it is necessary to discharge the waste chips, the filter plate 53 blocks and drives the waste chips to leave the machine. The handle 54 facilitates pulling the filter plate 53, and the rubber plug 51 seals the liquid storage tank 11, which is convenient for storing the used tapping liquid.

[0036] The two first cylinders 21, the linear motor 31, the telescopic electric main shaft 41, the tap 42 and the second cylinder 66 of the present utility model are purchased on the market. Technicians in this industry only need to install and operate according to the attached operation manuals, without the need for technicians in this field to perform creative labor.

[0037] The main functions achieved by the present utility model are: by setting the pressing device 02, the heat dissipation plate is automatically fixed, reducing the labor intensity of workers, and by setting the fuselage 01 and the collection device 05, the waste chips and the tapping liquid are automatically collected, filtered and separated, improving the usability of the machine; solving the existing technical problems that when tapping, workers need to manually fix parts, the labor intensity of workers is relatively high, and the existing chip loading groove will accumulate the tapping liquid when collecting the waste chips generated by tapping, making it difficult to recycle the waste chips and the usability of the machine is relatively poor.

[0038] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present utility model, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present utility model.
