Detailed implementation manners

[0026] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0027] The embodiment of the present utility model provides a percussion device for a punch, including a workbench 1 and a cylinder 2. Exemplarily, as Figures 1-6 shown.

[0028] The output end of the cylinder 2 penetrates through the workbench 1. The output end of the cylinder 2 is drivingly connected with a connecting piece 31. A lower connecting block 32 is fixedly connected to the lower side of the connecting piece 31. A lower connecting block 33 is arranged on the lower side of the upper connecting block 32. A hole-opening cutter head 34 is arranged inside the lower connecting block 33. A connecting mechanism 4 is arranged between the upper connecting block 32 and the lower connecting block 33.

[0029] The connecting mechanism 4 includes an inserting block 41 fixedly connected to the upper side of the lower connecting block 33. A slot 42 is opened on the lower side of the upper connecting block 32. The inserting block 41 is movably inserted inside the slot 42. A spring 43 is arranged inside the slot 42. One end of the spring 43 is fixedly connected to the upper connecting block 32. The other end of the spring 43 is fixedly connected with a clamping block 44. The clamping block 44 is movably clamped inside the inserting block 41.

[0030] A reset block 45 is slidably connected inside the upper connecting block 32. The reset block 45 is arranged above the clamping block 44. A hollow groove 46 is opened on one side of the upper connecting block 32. A mounting block 471 is arranged inside the hollow groove 46. A clamping block 472 is arranged on the outer side of the lower connecting block 33. A first screw 473 is threadedly connected between the mounting block 471 and the clamping block 472.

[0031] Specifically, the connection mechanism 4 between the upper connection block 32 and the lower connection block 33 can achieve the rapid installation and replacement of the hole-opening cutter head 34. The insertion block 41 is inserted into the slot 42, and the clamping block 44 driven by the spring 43 is automatically clamped, ensuring the reliability of the connection. At the same time, the installation and disassembly can be quickly completed without using additional tools;

[0032] In addition, the threaded connection design of the first screw 473 with the installation block 471 and the clamping block 472 further strengthens the connection mechanism 4, making the overall structure more reliable and reducing the loosening problem caused by vibration or impact;

[0033] In addition, when the hole-opening cutter head 34 needs to be replaced, the staff only needs to slide the reset block 45 to release the clamped state and quickly disassemble the connection block 33, thereby realizing the replacement of the hole-opening cutter head 34, reducing the time consumption when replacing the hole-opening cutter head 34, and improving the convenience of operation.

[0034] A drill sleeve 61 is slidably connected to the inner side of the lower connection block 33, and a second screw 62 is threadedly connected to the inner side of the drill sleeve 61, as Figures 1-6 shown.

[0035] A first chute 63 is opened on one side of the lower connection block 33. The second screw 62 is slidably connected to the inner side of the first chute 63. A limiting block 64 is fixedly connected to the outer side of the second screw 62, and the limiting block 64 is arranged on one side of the lower connection block 33.

[0036] A limiting groove 51 is opened inside the upper connection block 32. The limiting groove 51 communicates with the slot 42. A limiting block 52 is fixedly connected to the upper side of the clamping block 44, and the limiting block 52 is slidably connected to the inner side of the limiting groove 51.

[0037] A second chute 81 is opened inside the lower connection block 33. A slider 82 is fixedly connected to one side of the drill sleeve 61, and the slider 82 is slidably connected to the inner side of the second chute 81.

[0038] Specifically, the drill sleeve 61 can be conveniently replaced with the second screw 62 through the threaded connection therebetween. At the same time, the second screw 62 can drive the drill sleeve 61 and the limiting block 64 to slide together inside the first chute 63, so as to facilitate the staff to adjust the punching position of the hole-opening cutter head 34. At the same time, when the second screw 62 moves towards the inner side of the drill sleeve 61 by rotation, the limiting block 64 will approach the lower connection block 33, so as to fix the horizontal position of the hole-opening cutter head 34 through the friction between the limiting block 64 and the lower connection block 33, enabling it to punch smoothly and stably subsequently;

[0039] In addition, when the clamping block 44 drives the limiting block 52 to move, it will be restricted by the limiting groove 51, so that the movement of the clamping block 44 can be stable enough and is not likely to deviate or the like.

[0040] In addition, the setting of the second sliding groove 81 and the sliding block 82 can not only increase the stability of the drill sleeve 61 during sliding, but also play a certain supporting role for the drill sleeve 61 and the second screw rod 62, so that they are not likely to tilt, fall or shake during use.

[0041] A negative magnet 92 is fixedly connected to the inner side of the clamping block 44, a positive magnet 91 is fixedly connected to the inner side of the insertion block 41, and the positive magnet 91 and the negative magnet 92 attract each other magnetically, as Figures 1-6 shown.

[0042] A scale groove 71 is formed on one side of the lower connecting block 33, and a plurality of the scale grooves 71 are provided. A pointer 72 is fixedly connected to the outer side of the limiting block 64.

[0043] A third sliding groove 101 is formed inside the workbench 1. A moving block 102 is fixedly connected to one side of the upper connecting block 32. The moving block 102 is slidably connected inside the third sliding groove 101. A limiting rod 103 is arranged inside the third sliding groove 101, and the moving block 102 is slidably connected to the outer side of the limiting rod 103.

[0044] Specifically, the setting of the positive magnet 91 and the negative magnet 92 enables the positive magnet 91 and the negative magnet 92 to attract each other magnetically when the insertion block 41 is limited by the clamping block 44, increasing the firmness between the insertion block 41 and the clamping block 44 and reducing the shaking of the clamping block 44 inside the insertion slot 42.

[0045] In addition, the staff can observe how much distance the hole-opening cutter head 34 has moved through the scale groove 71 and the pointer 72, so as to facilitate the judgment of the position of the hole-opening cutter head 34. At the same time, the connection between the third sliding groove 101 and the moving block 102 enables the upper connecting block 32 to move up and down stably enough through the operation of the air cylinder 2 and is not likely to deviate. The limiting rod 103 can further limit the moving block 102 and increase the stability of the moving block 102 itself.

[0046] The working principle of a punching device trigger device proposed by an embodiment of the present utility model is as follows: when the device is in use, the staff can connect the hole-opening cutter head 34 to the inside of the drill sleeve 61, and then adjust the position of the hole-opening cutter head 34 by moving the second screw rod 62. When the hole-opening cutter head 34 moves to a suitable position, only need to rotate the second screw rod 62 to make the limiting block 64 and the lower connecting block 33 squeeze each other, and then the punching of the material can be realized through the operation of the air cylinder 2.

[0047] When it is necessary to replace the size and diameter of the punching hole, the staff can first rotate the first screw rod 473 and take out the first screw rod 473 from the inner sides of the mounting block 471 and the clamping block 472. At this time, the mounting block 471 and the clamping block 472 will no longer squeeze each other and are clamped on the outer side of the lower connecting block 33. Then, the reset block 45 can be pressed to squeeze the clamping block 44 through the reset block 45, so that the two clamping blocks 44 move to both sides, releasing the restriction on the insertion block 41. At this time, the lower connecting block 33 can drive the hole-opening cutter head 34 to fall out from the lower side of the upper connecting block 32.

[0048] After that, it is only necessary to reinstall the lower connecting block 33 adapted to different sizes to the lower side of the upper connecting block 32. During installation, only need to insert the insertion block 41 into the inner side of the slot 42, use the clamping block 44 to restrict the insertion block 41, and connect the mounting block 471 and the clamping block 472 through the first screw rod 473 again, and clamp them on the outer sides of the upper connecting block 32 and the lower connecting block 33, then the replacement of the hole-opening cutter head 34 and the lower connecting block 33 can be realized, so as to realize the replacement of the hole-opening cutter heads 34 with different diameters and sizes. And when it is necessary to drill holes with multiple different diameters and sizes, there is no need to prepare too many workbenches 1 and cylinders 2, reducing the cost during drilling.

[0049] Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
