[0024] Example 1

[0025] See also Figure 1-Figure 4 As shown, this embodiment provides an automated punching device for mechanical processing, including a workbench 1, a punching assembly 2 is installed on the workbench 1, and the punching assembly 2 includes a support frame 21 fixedly installed on the workbench 1, an impact cylinder 22 is fixedly installed on the top of the support frame 21, the output shaft of the impact cylinder 22 is fixedly connected to one end of a connecting rod 23, and a punch 24 is fixedly connected to the bottom of the connecting rod 23. The support frame 21 is fixedly installed on the workbench 1 to play a supporting role, and the impact cylinder 22 fixedly installed on the top of the support frame 21 provides power to enable the connecting rod 23 connected to the output shaft of the impact cylinder 22 to be connected. The rod 23 moves like a piston, and the punch 24 is fixedly connected to the bottom of the connecting rod 23. In order to prevent the punch 24 from falling off due to excessive impact force, a shock absorber is fixedly installed at the bottom of the pillar of the workbench 1. The shock absorber is used to reduce the shaking of the workbench 1. When the punching assembly 2 punches holes in the material, the downward impact force of the punch 24 will cause the workbench 1 to vibrate. The shock absorber is installed at the bottom of the pillar of the workbench 1. The shock absorber is mainly composed of a spring, a chassis, and a pillar located inside the spring and fixed on the upper part of the chassis. The shock absorber can reduce the vibration of the workbench 1 and make it stable, thereby improving the punching accuracy.

[0026] A clamping assembly 3 is provided on both sides of the punching assembly 2, and the clamping assembly 3 is used to fix the workpiece to be punched. The clamping assembly 3 includes a hollow fixing block 31, and the hollow fixing block 31 is fixed on the upper side of 1. The top and bottom of the inner cavity of the hollow fixing block 31 are provided with an L-shaped first tooth plate 341 and a second tooth plate 342. The bottom and top of the inner cavity of the fixing block 31 are provided with an L-shaped groove, and the first tooth plate 341 and the second tooth plate 342 are slidably engaged in the groove, and the first tooth plate 341 and the second tooth plate 342 are engaged in the L-shaped groove. On the one hand, it can prevent the first tooth plate 341 located at the top of the hollow fixed block 31 from falling, and on the other hand, it can ensure that the first tooth plate 341 and the second tooth plate 342 can move smoothly. The inner cavity of the hollow fixed block 31 is embedded with a motor 32, and the output shaft of the motor 32 is fixed with a gear 33. The first tooth plate 341 and the second tooth plate 342 are engaged with the gear 33. The motor 32 starts to run, driving the gear 33 to rotate, so that the first tooth plate 341 and the second tooth plate 342 engaged with the top and bottom teeth of the gear 33 start to move towards each other.

[0027] The first tooth plate 341 and the second tooth plate 342 are fixedly connected with a telescopic rod 35 on one side close to the punching assembly 2. The first tooth plate 341 and the second tooth plate 342 are respectively translated in opposite directions driven by the motor 31, so that the two clamping plates 36 make opposite movements. By controlling the two clamping plates 36 to make opposite movements, the two clamping assemblies 3 can clamp and release the object at the same time, which facilitates the clamping assembly 3 to fix the position of the object.

[0028] The first tooth plate 341 and the second tooth plate 342 move towards each other to drive the telescopic rod 35 to translate, and the position of the telescopic rod 35 is adjusted according to the length of the workpiece. The telescopic rod 35 is composed of two rods sleeved together, and one end of the rod sleeved inside is connected to a spring, and the other end of the spring is fixed inside the other rod, so that the length of the telescopic rod 35 changes. When the workpiece to be punched is irregular, such as L-shaped, the length of the telescopic rod 35 is adjusted according to the shape. The telescopic rod 35 connected to the first tooth plate 341 is extended, and the other telescopic rod 35 connected to the second tooth plate 342 is shortened to achieve a fixing effect. One end of the telescopic rod 35 passes through the fixed block 31 and is fixedly connected with an arc-shaped clamping plate 36. Several clamping plates 36 clamp and fix the workpiece located at the lower side of the punching assembly 2. The several clamping plates 36 fixedly connected to the telescopic rod 35 can change their positions in an arc-shaped trajectory through the translation of the first tooth plate 341 and the second tooth plate 342 and the free extension and retraction of the telescopic rod 35 to change the length. At this time, the fixing effect is achieved according to the shape and size of the workpiece.

[0029] A plurality of object detection sensors 4 are installed at the bottom of the support frame 21. The object detection sensors 4 are used to detect the shape of the material. When the material is placed, the object detection sensor 4 monitors the shape and size of the material, and then transmits it to the clamping component 3 to adjust its clamping plate 36 to a suitable angle. A funnel 5 is installed through the workbench 1, and the funnel 5 is located directly below the punch 24. When the punching component 2 performs a punching operation on the material, the waste and debris squeezed downward by the punch 24 can fall directly to the ground along the funnel 5. A controller 6 is fixedly installed on one side wall of the workbench 1. A display screen and a switch are provided on the side wall of the controller 6 away from the workbench 1. The controller 6 is connected to the impact cylinder 22, the motor 32, and the object detection sensor 4 through a wire, so that they constitute an integrated system operation, which is started by the switch, and the status of each component can be viewed on the display screen.

[0030] When the automatic punching device for mechanical processing of the present embodiment is used in specific use, the user first turns on the controller 6, and then drives the telescopic rod 35 fixedly connected to the first tooth plate 341 and the second tooth plate 342 respectively to move towards each other through the provided motor 31, so that the clamping plate 36 can move in an arc trajectory to adjust the position to achieve the effect of clamping and fixing. For example, for a pentagonal workpiece with an uneven surface, the clamping plate 36 can be clamped by adjusting the position of the clamping plate 36, and then workpieces of different sizes and shapes can be clamped, thereby speeding up the clamping progress and improving work efficiency.

[0031] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
