[0031] The following descriptions of the embodiments refer to the attached drawings for exemplifying specific embodiments in which the present utility model can be implemented.

[0032] The present utility model provides a drilling machine processing platform, the structure of which is as Figure 1 and Figure 2 shown, including a workbench 1 and a plurality of sub-fixture mechanisms 2. The plurality of sub-fixture mechanisms 2 are circumferentially distributed above the workbench 1, and the circumferential positions are adjustable. A clamping area is formed between the plurality of sub-fixture mechanisms 2; the sub-fixture mechanism 2 includes a rotation driving assembly 21 and an L-shaped clamping rod 22. Among them, the L-shaped clamping rod 22 includes a reinforcing rod 221 and a telescopic top member 222. The two ends of the reinforcing rod 221 are respectively fixedly connected to the output end of the rotation driving assembly 21 and the telescopic top member 222; the rotation driving assembly 21 is used to drive the L-shaped clamping rod 22 to rotate within the plane where the L-shaped clamping rod 22 is located, so that the telescopic top member 222 abuts against the surface of the workpiece 100.

[0033] Compared with the prior art, in a drilling machine processing platform provided by the present utility model, the circumferential positions of the plurality of sub-fixture mechanisms 2 distributed circumferentially are adjustable, and each of the sub-fixture mechanisms 2 is independently driven by its respective rotation driving assembly 21, so that the plurality of sub-fixture mechanisms 2 can respectively abut against multiple surfaces with different angles of a complex workpiece 100 from different directions, thereby realizing the clamping and fixing of the workpiece 100; at the same time, compared with the traditional straight clamping rod, the L-shaped clamping rod 22 can abut against the surface of the workpiece 100 with a smaller rotation amplitude, which is beneficial to reducing the volume of the platform; in addition, when the L-shaped clamping rod 22 is stressed, the clamping force is mainly along the axial direction of the telescopic top member 222, and the stress condition is good, which is beneficial to ensuring the reliability of the sub-fixture mechanism 2 during clamping.

[0034] Please continue to refer to Figure 1 , according to an embodiment of the present invention, in order to provide support for the arrangement of the plurality of sub-fixture mechanisms 2, the drilling machine processing platform further includes a ring frame 3 fixedly arranged above the workbench 1. A channel through which the drill bit can pass is formed in the middle of the ring frame 3; the plurality of sub-fixture mechanisms 2 are circumferentially and adjustably distributed on the inner wall of the ring frame 3.

[0035] As Figure 3 shown is a schematic diagram of the positional relationship of the sub-fixture mechanism 2 on the ring frame 3. Specifically, the ring frame 3 includes an upper ring frame 31, a lower ring frame 32 and a plurality of connecting members 33. The upper ring frame 31 and the lower ring frame 32 are arranged at intervals and are fixedly connected to each other through the connecting members 33. Among them, the top end of the inner wall of the upper ring frame 31 extends upward, and / or the bottom end of the inner wall of the lower ring frame 32 extends downward to form a slide rail 30.

[0036] According to an embodiment of the present invention, the sub-fixture mechanism 2 further includes a mounting bracket 23, the driving assembly 22 is fixedly arranged on the mounting bracket 23, a chute is formed on the mounting bracket 23 and the shape of the chute matches the shape of the slide rail 30, and the mounting bracket 23 is slidably matched with the slide rail 30 through the chute formed thereon, so that the mounting bracket 23 can be freely adjusted on the slide rail 30.

[0037] Further, since the sub-fixture mechanism 2 is movably arranged on the slide rail 30 through the mounting bracket 23, in order to lock the mounting bracket 23, the sub-fixture mechanism 2 further includes a locking assembly 24 for locking the mounting bracket 23, as Figure 4 shown in Figure 3 the enlarged schematic view of the partial B in, the locking assembly includes a bolt 241, a nut 242 and a washer 243, a locking hole is formed on the mounting bracket 23, and after the bolt 241 passes through the locking hole, the gap between the upper ring bracket 31 and the lower ring bracket 32 and the washer 243 in sequence, it is matched with the nut 242. Preferably, in order to improve the locking effect on the mounting bracket 23, a plurality of locking holes are arranged side by side on the mounting bracket 23, and correspondingly, a plurality of bolts 241 are arranged side by side.

[0038] Preferably, the connecting member 33 is bent into a "C" shape towards the outside of the ring bracket 3, so as to reserve a channel for the circumferential movement of the bolt 241 between the connecting member 33 and the ring bracket 3. When it is necessary to adjust the circumferential position of the sub-fixture mechanism 2, only need to loosen the nut 242, and then the sub-fixture mechanism 2 to be adjusted (including the locking assembly 24) can be integrally moved, without having to disassemble the bolt 241, the nut 242 and the washer 243 and then change the position of the mounting bracket 23, so that the circumferential position of the sub-fixture mechanism 2 is convenient to adjust.

[0039] It should be noted that the way of selecting the cooperation of the bolt 241, the nut 242 and the washer 243 to lock the mounting bracket 23 is only a preferred embodiment of the locking method. In other embodiments, other methods can also be adopted, such as the way of electromagnet adsorption to adsorb the mounting bracket 23 on the ring bracket 3.

[0040] Please continue to refer to Figure 2According to an embodiment of the present invention, the rotation driving assembly 21 includes a rotation driving member 211, a driving gear 212, a rotating shaft 213 and a driven gear 214, wherein the rotation driving member 211 is fixedly arranged on the mounting frame 23, and the output shaft of the rotation driving member 211 is perpendicular to the radius of the ring frame 3. Specifically, the rotation driving member 211 can be a motor; the driving gear 212 is fixedly installed on the output shaft of the rotation driving member 211; the rotating shaft 213 is rotatably arranged on the mounting frame 23, and the rotating shaft 213 is parallel to the output shaft of the rotation driving member 211; the reinforcing rod 221 is fixedly connected to the rotating shaft 213 at one end away from the telescopic top member 222; the driven gear 214 is fixedly arranged on the rotating shaft 213 and meshes with the driving gear 212.

[0041] It should be noted that, in the rotating drive assembly 21, the rotating drive member 211 drives the rotating shaft 213 and drives the L-shaped clamping rod 22 to rotate by meshing the driving gear 212 with the driven gear 214. This is only a preferred embodiment of driving the L-shaped clamping rod 22 to rotate in this scheme. In other embodiments, the rotating drive member 211 can also be driven to rotate by other transmission mechanisms such as belts or chains to achieve resistance and clamping of the workpiece 100.

[0042] According to an embodiment of the present invention, in order to increase the contact area between the L-shaped clamping rod 22 and the workpiece 100 to improve the clamping effect, the L-shaped clamping rod 22 further includes a top block 223 hinged to the distal end of the telescopic top member 222 .

[0043] It can be understood that, by hingedly connecting the top block 223 at the distal end of the telescopic top piece 222, the top block 223 can be in close contact with the surface of the workpiece regardless of the deflection angle of the telescopic top piece 222 in the vertical plane, so that the workpiece 100 can be better stressed; at the same time, it can also avoid the end of the telescopic top piece 222 directly contacting the workpiece 100, which may cause the telescopic top piece 222 or the surface of the workpiece 100 to be compressed and damaged.

[0044] Furthermore, a buffer pad (not shown in the figure) is fixedly arranged on the top block 223 to protect the surface of the workpiece 100. Specifically, the buffer pad can be a rubber pad.

[0045] Please continue to refer to Figure 1, according to an embodiment of the present invention, the drilling machine processing platform is used in cooperation with the drum - type conveyor line 1000. The workbench 1 includes a lifting driving member 11 and a plurality of pallets 12. The lifting driving member 11 is fixedly arranged at the bottom of the drum - type conveyor line 1000, and the plurality of pallets 12 are respectively fixedly connected to the plurality of output ends of the lifting driving member 11; and the width of the pallet 12 is less than the distance between adjacent drums on the drum - type conveyor line 1000. Specifically, the lifting driving member 11 can be a lifting cylinder or a hydraulic cylinder.

[0046] It can be understood that when the workpiece 100 is conveyed by the drum - type conveyor line 1000 to the clamping area, the lifting driving member 11 is activated and the workpiece 100 is lifted by the pallet 12, that is, the workpiece 100 can be processed; after the workpiece 100 is processed, the lifting driving member 11 drives the pallet 12 to descend, so that the workpiece 100 falls on the drum - type conveyor line 1000 again. By such a loading and unloading method to replace the traditional manual loading and unloading, the labor intensity of workers is reduced, which provides convenience for the processing of large workpieces.

[0047] For the convenience of understanding the present utility model, the following combines Figures 1 - 5 to elaborate in detail on the working principle of this solution:

[0048] As Figure 1 shown, when the workpiece 100 to be processed is conveyed by the drum - type conveyor line 1000 above the workbench 1, the lifting driving member 11 is activated and the workpiece 100 is lifted by the pallet 12.

[0049] Next, adjust the positions of each of the sub - fixture mechanisms 2 according to the shape of the workpiece 100, so that the sub - fixture mechanism 2 moves to the corresponding position of the surface to be clamped of the workpiece 100. Specifically, the corresponding position of the surface to be clamped can be understood as that when the sub - fixture mechanism 2 moves to this corresponding position, the plane where the L - shaped clamping rod 22 is located is perpendicular to the surface to be clamped.

[0050] Repeat the above - mentioned operation until all the sub - fixture mechanisms 2 are adjusted to the appropriate positions.

[0051] In each of the sub - fixture mechanisms 2, first activate the rotation driving member 211 to drive the L - shaped clamping rod 22 to rotate around the rotating shaft 213 until the axis of the telescopic ejector 222 is perpendicular to the corresponding surface to be clamped on the workpiece 100; then, activate the telescopic ejector 222 to make the telescopic ejector 222 extend until the top block 223 at the distal end of the telescopic ejector 222 abuts against the corresponding surface to be clamped on the workpiece 100.

[0052] When all the sub - fixture mechanisms 2 clamp the workpiece 100, it can be obtained Figure 5Schematic diagram of the working state of the drilling machine processing platform shown. Since Figure 5 What is shown is a plan view (which can be a front view), so only 2 L-shaped clamping rods 22 distributed left and right on both sides of the workpiece 100 are shown.

[0053] When the external drilling equipment is turned on, the drill bit can pass through the channel in the middle of the ring frame 3 to drill the workpiece 100. After the processing is completed, all the sub-fixture mechanisms 2 release the clamping force on the workpiece 100. Then, the lifting drive member 11 drives the support plate 12 to descend, so that the workpiece 100 falls back onto the roller conveyor line 1000, and the roller conveyor line can transport the workpiece 100 to the next process.

[0054] In summary, in the drilling machine processing platform provided by the present utility model, the plurality of circumferentially distributed sub-fixture mechanisms 2 can drive their respective L-shaped clamping rods 22 to rotate, so as to respectively abut against multiple surfaces of the workpiece 100 with different angles, thereby realizing the clamping and fixing of the workpiece; in addition, the L-shaped clamping rod 22 includes a reinforcing rod 221 and a telescopic top member 222. When clamping the workpiece 100, the clamping force is mainly along the axial direction of the telescopic top member 222, so that the force-bearing condition of the telescopic top member 222 is better.

[0055] It should be noted that although the present utility model is disclosed as above with specific embodiments, the above embodiments are not intended to limit the present utility model. Those of ordinary skill in the art can make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, the protection scope of the present utility model is subject to the scope defined by the claims.
