Description

Technical Field

[0001] This utility model relates to the field of punching device technology, specifically an automated punching device. Background Technology

[0002] A lifting arm is a component used in mechanical equipment or devices to lift objects. It consists of a boom, connecting parts, and a drive unit. Through different driving methods, the boom rotates around a fulcrum, lifting objects from a low position to a high position or adjusting their position. It has wide applications in construction, logistics, agriculture, fire protection, stage performances, and many other fields. During production, holes are usually punched in the boom for easy use. For example, hydraulic components such as hydraulic cylinders need to be installed on the lifting arm to achieve its lifting movement. These hydraulic components are fixed to the lifting arm with bolts or pins, so mounting holes need to be punched at appropriate locations to ensure accurate installation and reliable operation of the hydraulic components. Other components include connection holes, weight-reducing holes, and lubrication holes.

[0003] When punching holes, different punches are needed because the hole diameters are different. However, existing punching equipment is not convenient for quick punch replacement. Because the replacement is cumbersome, frequent punch replacement will increase the downtime of the equipment, resulting in reduced actual production time and lower production efficiency.

[0033] Example: Figures 1-8 As shown, this utility model provides a technical solution for an automated punching device, including a punching base 100;

[0034] Please refer to this carefully. Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7A stamping top plate 200 is provided above the stamping base 100. A movable vertical plate 210 is fixedly connected to the rear bottom of the stamping top plate 200.

This automated punching device drives the punching rod 213 to rotate through the turntable 212, the hollow circular plate 211, and the stepper motor 230. Then, the punching rod 213 is connected to the hollow arc block 222 through the connecting circular plate 223, which facilitates the quick connection of the punch 214 to the hydraulic cylinder 221. This facilitates the quick replacement of the corresponding punch 214, increases the effective working time of the equipment, reduces the downtime caused by replacing the punch 214, and thus improves the overall production efficiency.

[0035] Please refer to this carefully. Figure 1 , Figure 2 , Figure 3 and Figure 8Hollow plates 110 are provided on the top left and right sides of the stamping base 100. A rotating rod 111 is rotatably connected to the inner wall of the hollow plate 110 via bearings. The end of the rotating rod 111 extends to the outer side of the hollow plate 110 and is fixedly connected to a conical fixing block 112. A fixing groove 130 is provided on the top of the stamping base 100, located in front of the movable groove 120. The hollow plate 110 is slidably connected to the inner wall of the fixing groove 130. A bidirectional electric telescopic rod 131 is fixedly connected to the bottom of the inner wall of the fixing groove 130. The two output ends of the bidirectional electric telescopic rod 131 are fixedly connected to the left and right hollow plates 110 respectively. A rotating worm gear 132 is fixedly connected to the outer wall of the left rotating rod 111. A rotating worm 133 is rotatably connected to the inner wall of the left hollow plate 110 via bearings, and the rotating worm 133 meshes with the rotating worm gear 132. The left side of the inner wall of the movable groove 120 is rotatably connected to the rotating worm gear 132 via bearings. The device is equipped with an adjusting screw 140, a movable vertical plate 210, and a servo motor 141. The right side wall of the stamping base 100 is fixedly connected to the adjusting screw 140, and the right end of the adjusting screw 140 is fixedly connected to the output shaft of the servo motor 141. The front end of the rotating worm 133 extends to the outside of the left hollow plate 110 and is fixedly connected to a manual rotating disk. The outer wall of the tapered fixing block 112 is provided with a polyurethane rubber layer. This automated punching device facilitates the quick installation and positioning of the workpiece by using the tapered fixing block 112 in conjunction with the rotating rod 111, the hollow plate 110, and the bidirectional electric telescopic rod 131. The rotating worm wheel 132 in conjunction with the rotating worm 133 facilitates the flipping of the workpiece to adjust the processing position. The adjusting screw 140 in conjunction with the servo motor 141 facilitates the adjustment of the position of the punch 214. The two work together to achieve all-round processing of the workpiece, further improving production efficiency.

[0036] In use, the boom workpiece to be processed is placed on the auxiliary block 240. The power supply to the bidirectional electric telescopic rod 131 is then turned on. The output ends of both ends of the bidirectional electric telescopic rod 131 simultaneously drive the hollow plates 110 on both sides to move inwards. The hollow plates 110 slide in opposite directions within the fixing groove 130. Simultaneously, the rotating rod 111 drives the conical fixing blocks 112 on both sides to move together. The conical fixing blocks 112 on both sides then insert into the boom workpiece, clamping the workpiece from both sides, thus completing the installation and fixing of the workpiece. Next, the power supply to the hydraulic cylinder 221 is turned on, and the hydraulic cylinder 221... The output end drives the hollow arc block 222 to move downwards. Simultaneously, the hollow arc block 222 moves the connecting circular plate 223, which in turn drives the punch 214 downwards via the punch rod 213. The punch 214 punches holes in the workpiece. When punching is required in other positions on the workpiece, the manual rotating disc is turned to electrically rotate the worm gear 133. The worm gear 133 then drives the worm wheel 132 to rotate, which in turn drives the left rotating rod 111 to rotate. Since the workpiece is fixed by the conical fixing blocks 112 on both sides, the left rotating rod 111... 11. By rotating the left-side conical fixing block 112, and with the assistance of the right-side conical fixing block 112, the workpiece is rotated. The surface to be machined is then positioned. Next, the power to the servo motor 141 is turned on. The output shaft of the servo motor 141 rotates, causing the adjusting screw 140 to rotate. The adjusting screw 140 rotates, causing the movable vertical plate 210 to move within the movable slot 120. Simultaneously, the movable vertical plate 210 moves, causing the auxiliary block 240 to move as well, adjusting the punch 214 to the machining position for subsequent processing. When the punch 214 needs to be replaced... When the power supply to the stepper motor 230 is turned on, the output shaft of the stepper motor 230 rotates, causing the turntable 212 to rotate 90 degrees in the hollow circular plate 211. The rotation of the turntable 212 causes all the punch rods 213 to rotate simultaneously. The currently used punch rod 213 causes the connecting circular plate 223 and the punch 214 to rotate to one side. At the same time, the punch rod 213 to be used causes the connecting circular plate 223 to enter the hollow arc block 222, so that the punch 214 to be used is connected to the hydraulic cylinder 221 and can be used. Repeating the above operation allows for quick replacement of the corresponding punch 214 according to the usage.

[0037] It should be noted that the principle of the stepper motor driving the turntable to rotate 90 degrees each time mentioned in this application is that the stepper motor drives the object to rotate 90 degrees each time based on its working principle of converting electrical pulse signals into angular displacement. It uses microstepping drive technology to precisely control the step angle, and then transmits the motor rotation to the object according to the set transmission ratio through the transmission mechanism, so as to achieve the object to rotate 90 degrees each time. This is existing technology and therefore will not be elaborated further.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
