[0025] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0026] like Figure 1 to Figure 5 As shown, a high-speed automatic punching machine of this embodiment includes a machine base 1, on which a feed trough 3, a clamping mechanism 4, a first high-speed drill bit 6 and a moving mechanism 7 are arranged; a first drilling hole 31 is arranged on the side of the feed trough 3, and a leveling machine 12 is arranged at one end of the feed trough 3. For example, a platform vibration motor of model RZD10-20C is used to drive the feed trough 3 to vibrate regularly, so that the workpiece moves on the feed trough 3; the clamping mechanism 4 is arranged above the feed trough 3, and is used to clamp and fix the workpiece in the feed trough 3; the first high-speed drill bit 6 is arranged on the side of the feed trough 3; the moving mechanism 7 is connected to the first high-speed drill bit 6 to drive the first high-speed drill bit 6 to extend into the first drilling hole 31 to punch the workpiece in the feed trough 3.

[0027] Specifically, the moving mechanism 7 includes a first slide rail 71, a first slider 72, a second slide rail 73, a second slider 74, a first cylinder 77, a second cylinder 78 and a sliding table 76. The first slide rail 71 is arranged along the length direction of the feeding trough 3, the first slider 72 is slidably arranged on the first slide rail 71, the sliding table 76 is fixedly connected to the first slider 72, the second slide rail 73 is perpendicular to the feeding trough 3, the second slider 74 is slidably arranged on the second slide rail 73, the first high-speed drill 6 is connected to the second slider 74, the first cylinder 77 is used to drive the sliding table 76 to slide along the first slide rail 71, and the second cylinder 78 is used to drive the first high-speed drill 6 to slide along the second slide rail 73. The first cylinder 77 is connected to one side of the sliding table 76, and a limit block 11 is provided on the other side of the sliding table 76 to limit the moving distance of the sliding table 76. A spring 75 is sleeved on the second slide rail 73, and both ends of the spring 75 are respectively connected to the second slider 74 and the sliding platform 76. The second cylinder 78 is arranged at one end of the second slide rail 73. The second cylinder 78 can be telescopically acted on the second slider 74 and compress the spring 75. When drilling is completed, the second cylinder 78 retracts, and the second slider 74 rebounds under the action of the spring 75, so that the first high-speed drill bit 6 is separated from the workpiece and moves out of the first drilling hole 31.

[0028] The first slide rail 71 and the second slide rail 73 each include two, so that the sliding table 76 runs more smoothly. A first high-speed drill 6 is provided on the second slider 74 of each second slide rail 73. They have the same drilling direction, but the drill size is different, so as to drill holes of different sizes on the workpiece. Under the drive of the moving mechanism 7, the two first high-speed drills 6 can move to align with the first drilling hole 31 to improve the drilling accuracy. At the same time, only when the first high-speed drill 6 moves to align with the first drilling hole 31, the workpiece will be drilled to avoid the scrapping of the workpiece caused by misaligned drilling.

[0029] In addition, in some processing, it is necessary not only to drill holes on the side of the workpiece but also on the bottom. Therefore, a second high-speed drill bit 8 is arranged at the lower end of the feed trough 3, and a second drilling hole 32 is arranged on the bottom surface of the feed trough 3. A third cylinder 9 is arranged at the lower end of the second high-speed drill bit 8 for driving the second high-speed drill bit 8 to move up and down, so that the second high-speed drill bit 8 enters the feed trough 3 from the second drilling hole 32 to drill a hole on the bottom of the workpiece.

[0030] The clamping mechanism 4 includes a mounting plate 41, a third slide rail 42, a third slider 43, a fourth cylinder 44, a fifth cylinder 45 and a pressure plate 46. The mounting plate 41 is arranged on the side of the feed trough 3, the third slide rail 42 is arranged on the mounting plate 41 along the length direction of the feed trough 3, the third slider 43 is slidably arranged on the third slide rail 42, the fourth cylinder 44 is arranged along the direction of the third slide rail 42 and is connected to the third slider 43, the fifth cylinder 45 is vertically fixed on the third slider 43, and the pressure plate 46 is arranged at the lower end of the fifth cylinder 45 for clamping the workpiece in the feed trough 3. The cross-section of the pressing plate 46 is L-shaped, and a positioning groove 47 for clamping the workpiece is provided on the lower side of the pressing plate 46. For the convenience of processing, the positioning groove 47 includes two spaced apart arrangements. After the workpiece enters the first positioning groove 47, the pressing plate 46 presses the workpiece to perform side drilling, and then the fourth cylinder 44 drives the pressing plate 46 to move a distance to reach the second positioning groove 47. After the pressing plate 46 is lifted, the fourth cylinder 44 drives the pressing plate 46 to move in the opposite direction until the second positioning groove 47 is opposite to the workpiece. The pressing plate 46 moves downward to position the workpiece, and at the position of the second positioning groove 47, the second high-speed drill bit 8 moves upward to drill a hole at the bottom of the workpiece.

[0031] A vibrating tray 2 is provided on the side of the machine base 1 for loading the workpiece to be drilled. The vibrating tray 2 is connected to the feeding trough 3. The workpiece enters the feeding trough 3 for processing under the action of the vibrating tray 2. A finished product box 5 for collecting finished products is provided at one end of the feeding trough 3 so as to load the finished products. For easy operation, a control panel 10 for controlling the clamping mechanism 4 and the moving mechanism 7 is provided on the machine base 1.

[0032] The working principle of the high-speed automatic punching machine is as follows: the workpiece enters the feeding trough 3 through the vibration of the vibrating material tray 2, and moves on the feeding trough 3 with the vibration of the leveling machine 12. When the workpiece moves to the positioning groove 47 of the pressure plate 46, the leveling machine 12 stops vibrating, and the first cylinder 77 acts on the sliding table 76, and the first slider 72 moves on the first slide rail 71, thereby driving the first high-speed drill 6 to align it with the first drilling hole 31. Under the action of the second cylinder 78, the second slider 74 is pushed, so that the first high-speed drill 6 extends from the first drilling hole 31 into the feeding trough 3 to punch the side of the workpiece. Then, the fourth cylinder 44 drives the third slider 43 to slide along the third slide rail 42, and the workpiece slides to the top of the second drilling hole 32. Under the action of the fifth cylinder 45, the pressure plate 46 presses the workpiece, and the third cylinder 9 below drives the second high-speed drill 8 to move upward, and the second high-speed drill 8 enters the feeding trough 3 from the second drilling hole 32 to punch the bottom of the workpiece. After the drilling is completed, the pressing plate 46 is lifted to make the workpiece disengage from the positioning groove 47, and the leveling machine 12 is started to make the workpiece enter the finished product box 5, thereby completing the drilling process on the workpiece.

[0033] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
