[0028] It is understandable that, referring to Figures 1 to 4 The automatic punching device of the present invention includes a frame 100, a feeding mechanism 200 and a punching mechanism 300. The frame 100 is fixedly connected to a positioning cylinder 110. The side wall of the positioning cylinder 110 is provided with a positioning hole 111. The positioning cylinder 110 matches the shape of the workpiece; the feeding mechanism 200 includes a clamping assembly 210 and a moving assembly 220. The clamping assembly 210 includes a support seat 211, a first driving member 212 and two clamping blocks 213. The support seat 211 is slidably connected to the frame 100. The two Each clamping block 213 is slidably connected to the support base 211, the first driving member 212 is used to drive the two clamping blocks 213 to approach each other to clamp the workpiece, and the moving assembly 220 is used to drive the support base 211 to move in the direction close to the positioning cylinder 110 so that the workpiece is sleeved on the positioning cylinder 110; the stamping mechanism 300 includes a second driving member 310 and a pressing head 320, the pressing head 320 is arranged at the movable end of the second driving member 310, and the second driving member 310 is used to drive the pressing head 320 to extend into the positioning hole 111.

[0029] The positioning cylinder 110 is fixedly connected to the frame 100. The positioning cylinder 110 is provided with a positioning hole 111. By setting the positioning cylinder 110 to match the shape of the workpiece, the workpiece can be stably positioned in the positioning cylinder 110. The support seat 211 is slidably connected to the frame 100. The two clamping blocks 213 are slidably connected to the support seat 211. The workpiece is set between the two clamping blocks 213. Then the first driving member 212 drives the two clamping blocks 213 to move closer to each other so that the two clamping blocks 213 clamp the workpiece. Then the moving assembly 220 drives the support seat 211. Move toward the direction close to the positioning cylinder 110 so that the workpiece is mounted on the positioning cylinder 110 and the workpiece can be stably placed in the positioning cylinder 110. Finally, the second driving member 310 drives the pressing head 320 to move toward the direction close to the positioning cylinder 110 so that the pressing head 320 can extend into the positioning hole 111, thereby automatically punching the workpiece without the need for manual gripping of the workpiece, reducing the possibility of the workpiece loosening, improving the punching accuracy of the workpiece, and preventing workers from being injured by the pressing head 320, thereby improving the safety of the operation and the reliability of the punching device.

[0030] It should be noted that the first driving member 212 includes two linear cylinders, which correspond one to one with the clamping blocks 213. The two linear cylinders move synchronously. The two linear cylinders cooperate to drive the two clamping blocks 213 to move closer to or away from each other, so that the two clamping blocks 213 can automatically clamp or release the workpiece, thereby realizing automatic clamping of the workpiece and improving production efficiency.

[0031] In addition, the second driving member 310 can be a linear cylinder, a linear oil cylinder, a linear slide module, etc., as long as it can drive the pressure head 320 to move linearly, which will not be described in detail here.

[0032] It is understandable that, referring to Figure 1 and Figure 2 The end of the support base 211 facing away from the positioning cylinder 110 is provided with a first stopper 214, which can abut against the workpiece. The first stopper 214 is provided at the end of the support base 211 facing away from the positioning cylinder 110. By providing the first stopper 214 to abut against the workpiece, when the moving assembly 220 drives the support base 211 toward the positioning cylinder 110, the first stopper 214 can drive the workpiece to be smoothly inserted into the positioning cylinder 110, thereby preventing the workpiece from slipping off the two clamping blocks 213 and improving the loading stability of the workpiece.

[0033] It should be noted that the shape of the positioning cylinder 110 matches the shape of the workpiece. This creates significant resistance when inserting the workpiece into the positioning cylinder 110, making it susceptible to loosening from the two clamping blocks 213. This can lead to inaccurate workpiece positioning and affect the accuracy of the drilling position. The provision of the first stop 214 ensures that the workpiece is stably positioned within the positioning cylinder 110, providing a stable force on the workpiece and improving loading stability.

[0034] In addition, by providing the first stopper 214 , it is possible to conveniently position the workpiece on the support seat 211 , thereby stabilizing the position of the workpiece and improving the convenience of loading the workpiece.

[0035] Specifically, refer to Figure 1 、 Figure 3 and Figure 5 The second stopper 215 is provided at one end of the support seat 211 away from the first stopper 214, and the side wall of the positioning cylinder 110 is recessed to form a guide groove 112. The second stopper 215 can slide in the guide groove 112 and abut against the end of the workpiece. The second stopper 215 is provided at one end of the support seat 211 away from the first stopper 214, and the side wall of the positioning cylinder 110 is recessed to form a guide groove 112. By setting the second stopper 215 to slide in the guide groove 112, the second stopper 215 can abut against the end of the workpiece, so that when the moving assembly 220 drives the support seat 211 to reset, the second stopper 215 can drive the workpiece out of the positioning cylinder 110, thereby preventing the workpiece from being stuck on the positioning cylinder 110 and improving the processing stability of the workpiece.

[0036] It should be noted that the moving component 220 drives the support seat 211 to move in the direction close to the positioning cylinder 110, and the first stop block 214 and the two clamping blocks 213 cooperate to put the workpiece on the positioning cylinder 110, thereby realizing automatic loading of materials. Then the moving component 220 drives the support seat 211 to move in the direction away from the positioning cylinder 110, so that the second stop block 215 can abut against the workpiece, thereby driving the workpiece out of the positioning cylinder 110 through the second stop block 215, realizing automatic unloading of materials and improving the processing efficiency of the workpiece.

[0037] It is understandable that, referring to Figure 2 and Figure 4 Multiple rubber strips 216 are spaced apart on the inner side of the clamping block 213 and arranged along the direction of movement of the support base 211. The multiple rubber strips 216 are spaced apart on the inner side of the clamping block 213 and arranged along the direction of movement of the support base 211 to stabilize the position of the workpiece on the clamping block 213, reduce the possibility of the workpiece rotating in the clamping block 213, improve the clamping stability of the workpiece, and enhance the drilling accuracy of the workpiece.

[0038] Specifically, refer to Figure 4 The rubber strip 216 is detachably connected to the clamping block 213, which facilitates maintenance of the rubber strip 216, extends the service life of the clamping block 213, and improves the reliability of the automatic punching device. The rubber strip 216 can be fixed to the clamping block 213 by bolts, adhesives, etc., which will not be described in detail here.

[0039] The cross-section of the rubber strip 216 is semicircular to reduce the contact area between the rubber strip 216 and the workpiece, thereby slowing down the wear of the rubber strip 216 and improving the clamping accuracy of the workpiece and the processing quality of the workpiece.

[0040] It is understandable that, referring to Figure 1 、 Figure 3 and Figure 5 The support base 211 is fixedly connected to a push plate 113, and the push plate 113 slides against the inner wall of the positioning cylinder 110. The push plate 113 is fixedly connected to the support base 211 so that the push plate 113 can move synchronously with the support base 211. The push plate 113 is slidably connected to the inner wall of the positioning cylinder 110 so that when the moving assembly 220 drives the support base 211 to move, the push plate 113 can slide against the inner wall of the positioning cylinder 110, thereby automatically cleaning the waste in the positioning cylinder 110, preventing the waste from accumulating in the positioning cylinder 110, and improving the accuracy of the punching.

[0041] It should be noted that the third drive member 221 drives the ram 320 into the positioning hole 111, causing the punching waste of the workpiece to fall into the interior of the positioning cylinder 110, resulting in the waste easily accumulating in the positioning cylinder 110 and getting stuck in the positioning hole 111, affecting the accuracy of the punching. In addition, the positioning cylinder 110 has a small inner diameter, which makes it difficult to clean. By arranging the push plate 113 to move synchronously with the support seat 211, the push plate 113 can push the waste in the positioning cylinder 110 out of the positioning cylinder 110, thereby avoiding waste accumulation and improving the accuracy and efficiency of the workpiece punching.

[0042] Specifically, refer to Figure 3 and Figure 5The inner wall of the positioning cylinder 110 is provided with a protruding guide bar 114, and the push plate 113 is provided with a groove 115, and the guide bar 114 is located in the groove 115. The guide bar 114 is provided on the inner wall of the positioning cylinder 110, and the push plate 113 is provided with a groove 115. By providing the guide bar 114 and being located in the groove 115, the movement direction of the push plate 113 can be guided, so that the push plate 113 can move stably, avoid the push plate 113 from tilting, and prevent the push plate 113 from getting stuck on the inner wall of the positioning cylinder 110, thereby improving the reliability of the automatic punching device.

[0043] There are multiple guide bars 114 and grooves 115 , and the guide bars 114 and grooves 115 are in one-to-one correspondence. By providing multiple guide bars 114 and multiple grooves 115 , the movement stability of the push plate 113 can be improved.

[0044] It should be noted that the positions of the guide grooves 112 correspond to each other, which can facilitate the processing of the positioning tube 110 and reduce the processing difficulty and cost of the positioning tube 110 .

[0045] It is understandable that, referring to Figure 1 The moving assembly 220 includes a third driving member 221 and a guide column 222. The guide column 222 is fixedly connected to the frame 100, and the support base 211 is slidably connected to the guide column 222. The third driving member 221 is used to drive the support base 211 to slide on the guide column 222. The guide column 222 is fixedly connected to the frame 100, and the support base 211 is slidably connected to the guide column 222. The third driving member 221 can drive the support base 211 to move smoothly along the axial direction of the guide column 222, thereby improving the movement accuracy and stability of the support base 211 and improving the stability of workpiece loading.

[0046] It should be noted that the third driving member 221 can be a linear cylinder, an electric push rod, a linear slide module, etc., which will not be described in detail here.

[0047] It is understandable that, referring to Figure 2 and Figure 3 Two support plates 120 are protruding from the bottom side of the frame 100. The support plates 120 are provided with multiple mounting holes 121, and fasteners are inserted into the mounting holes 121. The two support plates 120 are respectively provided on both sides of the frame 100. By providing multiple mounting holes 121 on the support plates 120, the support plates 120 can be fixed to a workbench or the ground with fasteners, thereby stabilizing the position of the frame 100, preventing the frame 100 from shaking, improving the accuracy of the punching, and enhancing the reliability of the automatic punching machine.

[0048] It should be noted that the fasteners may be bolts, screws, etc., which can fix the position of the support plate 120 and are not described in detail here.

[0049] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
