Detailed Description of the Preferred Embodiments

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] Refer to Figures 1-3, an embodiment provided by the present utility model: a punching device for the side plate of a busbar trunking, including a workbench 1. The workbench 1 serves as the base of the entire device, providing a stable support platform. A chute one 2 is provided on the workbench 1, and a slider one 3 is slidably arranged on the chute one 2. The chute one 2 is used for the sliding of the slider one 3 to ensure that it can move in a straight line. A clamping cylinder 4 is fixedly installed on the slider one 3, and the output end of the clamping cylinder 4 is fixedly connected with a movable clamping block 5. The clamping cylinder 4 pushes the movable clamping block 5 to clamp the busbar trunking side plate body 9. The bottom of the movable clamping block 5 is fixedly connected with a slider two 6. A chute two 7 is provided on the slider one 3, and the slider two 6 slides in the chute two 7. The slider two 6 ensures that the movable clamping block 5 can move smoothly on the chute two 7. A fixed clamping block 8 is fixedly connected to the slider one 3. The busbar trunking side plate body 9 is arranged in the rectangle formed by the chute two 7 and the fixed clamping block 8. A curved connecting shaft 10 is hinged to the side surface of the movable clamping block 5, and the middle section of the curved connecting shaft 10 is hinged to the fixed clamping block 8.

[0028] A punching table 11 is fixedly connected to the workbench 1. An punching cylinder 12 is fixedly connected to the upper part of the punching table 11. The output end of the punching cylinder 12 penetrates through the punching table 11 and is fixedly connected with a punching head 13. The punching cylinder 12 is used to drive the punching head 13 to perform punching operations. A connecting plate 14 is fixedly connected to the output end of the punching cylinder 12. The connecting plate 14 is used to transmit the driving force of the cylinder. A connecting rod 15 is fixedly connected to the connecting plate 14. A sliding rod 16 is slidably connected in the connecting rod 15. A pre-pressing block 17 is fixedly connected to the bottom of the connecting rod 15. The sliding rod 16 transmits the driving force of the punching cylinder 12 to the pre-pressing block 17. A spring one 18 is fixedly connected to the pre-pressing block 17. One end of the spring one 18 away from the pre-pressing block 17 is fixedly connected to the connecting plate 14. A hole 19 is provided on the pre-pressing block 17. When the punching cylinder 12 drives the punching head 13 to move downward, it drives the connecting plate 14, the connecting rod 15, the sliding rod 16, and the pre-pressing block 17 to move downward. The pre-pressing block 17 will contact the busbar trunking side plate body 9 prior to the punching head 13. Then the spring one 18 contracts, and the sliding rod 16 slides in the connecting rod 15. The punching head 13 continues to move downward and punches through the hole 19 on the busbar trunking side plate body 9.

[0029] A positioning installation box 20 is fixedly connected to the workbench 1, and a slider 3 21 is slidably provided in the positioning installation box 20. One end of the slider 3 21 penetrates the positioning installation box 20 and is fixedly connected to a conical head 22. The conical head 22 is arranged on the outside of the positioning installation box 20. The end of the slider 3 21 away from the conical head 22 is fixedly connected to a spring 23. The end of the spring 23 away from the slider 3 21 is fixedly connected to the inner wall of the positioning installation box 20. A plurality of concave scale lines 24 are provided on the side of the slider 3. When the concave scale lines 24 contact the conical head 22, the conical head 22 resists the concave scale lines 24, and the slider 3 cannot Continue to move on the slide groove 2, when the concave scale line 24 separates from the conical head 22, the slider 3 forces the conical head 22 to shrink, and the slider three 21 also shrinks accordingly, and then the spring two 23 is compressed. When the concave scale line 24 moves to the next concave scale line 24 and contacts the concave scale line 24, the spring two 23 recovers, the conical head 22 and the slider three 21 move outward, the conical head 22 conflicts with the concave scale line 24, and the slider 3 cannot continue to move on the slide groove 2, so that the precise positioning of the bus duct side plate body 9 can be achieved through the contact and separation of the concave scale line 24 on the slider 3 and the conical head 22.

[0030] Support legs 25 are installed at the four corners of the bottom of the workbench 1, and the support legs 25 provide stability for the entire device.

[0031] The hole 19 is arranged directly below the punching head 13 . The size of the hole 19 matches the size of the punching head 13 . The punching head 13 punches holes in the bus duct side plate body 9 through the hole 19 .

[0032] The conical head 22 abuts against the concave scale line 24 .

[0033] The size of the pre-pressing block 17 is smaller than the bus duct side plate body 9 , and the pre-pressing block 17 contacts the bus duct side plate body 9 before the punching head 13 when moving downward.

[0034] Working principle: First, the operator places the bus duct side panel body 9 in the rectangular area surrounded by the slider 3 and the fixed clamp block 8 of the workbench 1 to ensure that the bus duct side panel body 9 is stably placed in the device, and then starts the clamping cylinder 4. The output end of the cylinder pushes the movable clamp block 5 to move along the slider 3. The movement of the movable clamp block 5 drives the curved connecting shaft 10 to rotate around its hinge point with the fixed clamp block 8, so that the two movable clamp blocks 5 move toward each other to achieve a tight clamping of the bus duct side panel body 9. The operator pushes the slider 3 and uses the concave scale line 24 on the side of the slider 3 to contact and separate with the conical head 22 outside the positioning installation box 20. Through this contact and separation mechanism, the precise positioning of the bus duct side panel body 9 is achieved;

[0035] Before the punching operation, the punching cylinder 12 drives the connecting plate 14, the connecting rod 15, the sliding rod 16 and the preloading block 17 to move downward. The preloading block 17 will contact the busbar groove side plate body 9 prior to the punching head 13, providing a stable support point. Then the operator starts the punching cylinder 12, and the output end of the cylinder drives the punching head 13 to move downward. The punching head 13 smoothly and evenly passes through the hole 19 to perform the punching operation on the busbar groove side plate body 9. During the downward movement of the punching head 13, the first spring 18 contracts, and the sliding rod 16 slides within the connecting rod 15, which helps to absorb the impact force during the punching process and reduce the damage to the busbar groove side plate body 9. After the punching head 13 completes the punching operation, the punching cylinder 12 retracts, and components such as the punching head 13 and the preloading block 17 return to the initial state;

[0036] After punching, the clamping cylinder 4 is released, so that the movable clamping block 5 is separated from the busbar groove side plate body 9, thus completing the entire punching work process. Finally, the operator can take out the busbar groove side plate body 9 that has been punched and perform subsequent processing or installation work.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
