DETAILED DESCRIPTION

[0033] The following will be described in detail in combination with the accompanying Figures 1-6 The present application will be further described in detail.

[0034] The embodiment of the present application discloses a multi-drill puncher. As shown inFigure 1 The multi-bit puncher comprises a machine body 11 and a base frame 1, the base frame 1 is provided with a horizontal workbench 12, the machine body 11 is installed above the workbench 12, the workbench 12 is provided with a clamping groove 13 for placing a workpiece, the two ends of the clamping groove 13 are both penetrated out of the workbench 12 along the length direction of the workbench 12, the width of the clamping groove 13 is matched with the width of the workpiece, the bottom of the clamping groove 13 is provided with a counterbore 14 corresponding to each bit of the machine body 11, the inner diameter of the counterbore 14 is the same as the diameter of the corresponding bit, and the base frame 1 is provided with a pressing assembly 2 for pressing the workpiece in the clamping groove 13.

[0035] As Figure 2 , Figure 3 and Figure 4 , the pressing assembly 2 comprises a support 21 fixed on the base frame 1, the support 21 is opposite to one end of the clamping groove 13 along the length direction, the support 21 is hingedly connected with a swing rod 22, one end of the swing rod 22 is hingedly connected with a connecting rod 25, the other end of the swing rod 22 is connected with a pressing rod 23 through a locking screw 26, the pressing rod 23 is located at one end of the swing rod 22 close to the workbench 12, the swing rod 22 and the pressing rod 23 are both provided with waist-shaped grooves 27 distributed along the length direction, the locking screw 26 is sequentially penetrated through the two waist-shaped grooves 27 and is threadedly connected with a locking nut 261, the locking nut 261 is abutted against the pressing rod 23 to fix the swing rod 22 and the pressing rod 23. The pressing rod 23 is obliquely distributed and is threadedly connected with a sleeve 28 at the obliquely downward end, the sleeve 28 is fixedly connected with a conical pressing block 29 at the end, the pressing block 29 is located above the clamping groove 13, and the outer wall of the pressing block 29 is covered with a rubber pad 291. The support 21 is horizontally installed with an air cylinder 24, the air cylinder 24 is located on the length direction of the clamping groove 13, and the end of the piston rod of the air cylinder 24 is hingedly connected with the end of the connecting rod 25 away from the swing rod 22.

[0036] As Figure 2 , Figure 5 and Figure 6 , the base frame 1 is vertically fixed with a water baffle 3 distributed along the periphery of the base frame 1, the base frame 1 is provided with a water outlet 32, and the base frame 1 is fixed with a collecting box 31 below the water outlet 32, the inner side wall of the collecting box 31 is provided with a plurality of pads 33, each pad 33 is located at the same horizontal height, and each pad 33 is commonly supported with a frame 34, the outer contour of the frame 34 is matched with the inner contour of the collecting box 31, the frame 34 is provided with a filter screen 341, and the frame 34 is connected with a plurality of hooks 342, each hook 342 is penetrated out of the water outlet 32 and is lapped on the base frame 1, so that the operator can take out the frame 34 from the collecting box 31 for loading and unloading through the hooks 342. The side wall of the collecting box 31 is connected with a water delivery pipe 35, and the water delivery pipe 35 is used for communicating with the cooling liquid circulating system of the puncher.

[0037] The principle of the embodiment of the application is that when punching, the operator opens the cooling liquid of the puncher and sprays it on the drill bit, then places the workpiece in the clamping groove 13, the cylinder 24 drives the connecting rod 25 to advance, the connecting rod 25 pushes the swing rod 22 to rotate upward at the hinged end, so that the other end of the swing rod 22 drives the pressing rod 23 to rotate downward, the pressing block 29 abuts against the workpiece and presses the workpiece tightly in the clamping groove 13, and the drill bit of the puncher descends to drill the workpiece.

[0038] After the drilling is completed, the drill bit moves upward, the cylinder 24 drives the connecting rod 25 to move backward, the connecting rod 25 pulls the swing rod 22 to rotate, so that the pressing block 29 rotates upward and separates from the workpiece, the operator takes out the workpiece and puts in a new workpiece, and repeats the previous steps. Since the workpiece is limited in the clamping groove 13 and the pressing block 29 presses and fixes the workpiece, the possibility of displacement of the workpiece during drilling is reduced, so that the drilling precision of the workpiece is improved; when the size of the workpiece changes, the operator loosens the locking screw 26, moves the pressing rod 23 to adjust the relative position between the pressing rod 23 and the swing rod 22, and ensures that the pressing block 29 abuts against the workpiece when the swing rod 22 is pressed downward.

[0039] During the drilling process, the cooling liquid flows from the workbench 12 to the base frame 1, and then flows into the collecting box 31 from the drain port 32. The filter screen 341 filters the cooling liquid, reduces the content of impurities in the cooling liquid, the operator connects the water inlet pipe 35 with the cooling liquid circulation system of the puncher, so that the cooling liquid in the collecting box 31 is re-input into the puncher for recycling, and resources are saved.

[0040] The above are preferred embodiments of the application, which do not limit the protection scope of the application, therefore: any equivalent changes made on the structure, shape and principle of the application should be covered within the protection scope of the application.
