Description

Technical Field

[0001] The utility model relates to the technical field of punching devices, in particular to an adjustable punching device for electric power installation. Background Art

[0002] In power installation construction, a punching device usually refers to a tool or device used to punch holes in building structures such as walls and pipes, or to punch holes in some installation parts such as mounting plates and bridges. This type of punching device usually requires greater power and durability to meet the needs of drilling holes in materials such as concrete, brick walls, and steel bars.

[0003] When existing punching devices are used to punch holes in mounting plates, bridge frames and other mounting parts, in actual construction, workers mostly use pistol drills to drill holes. However, this punching method cannot ensure that the punching distance is the same. If deviation occurs, the mounting plate or some mounting parts may not be installed. Utility Model Content

The slider 22 penetrates the bracket 3 and is slidably connected. A spring 23 is fixedly connected to the bottom surface of the slider 22. The pistol drill 1 is aligned with the through hole of the support plate 21, and the pistol drill 1 is pressed downward against the support plate 21, so that the support plate 21 drives the connecting block 24 to slide downward. At the same time, the support plate 21 will drive the slider 22 to press the spring 23. The bottom end of the spring 23 is fixedly connected to the inner side of the bracket 3, and the top surface of the connecting block 24 is fixedly connected to the bottom surface of the support plate 21. The inner side of the connecting block 24 is fixedly connected to a shaft 25, and the shaft 25 penetrates and is rotatably connected to a lever 26. The slide plate 29 is slidably connected to the inner side of the bracket 3. A toggle groove 210 is provided on the top surface of the slide plate 29, and a placement plate 220 is fixedly connected to the side of the slide plate 29. The toggle rod 26 toggle the slide plate 29 to slide, and the slide plate 29 will drive the power installation plate clamped by the placement plate 220 to slide together. When the toggle rod 26 stops toggle, the drill bit of the pistol drill 1 has not touched the power installation plate. Continue to push the pistol drill 1 downward to drill holes in the installation plate. A bolt 214 penetrates the top surface of the slide plate 29 and is rotatably connected. The bolt 214 penetrates and is threadedly connected with a clamping plate 213. When in use, first insert the firmware such as the power installation plate that needs to be punched between the clamping plate 213 and the placement plate 220, and tighten the bolt 214 to clamp the clamping plate for power installation with the placement plate 220. The slide plate 29 is L-shaped, and the left side of the slide plate 29 penetrates and is slidably connected with a positioning rod 211. When the connection block 24 slides downward, the lever 26 is driven to move downward together through the shaft 25, and the lever 26 is gradually inserted into the toggle groove 210, and also contacts the inclined surface of the cross column 215, thereby forcing the lever 26 to rotate about the axis of the shaft 25, and then the lever 26 drives the slide plate 29 to slide.

The inner side of the connection block 24 is fixedly connected with an arc rod 27, which penetrates the lever 26 and has the same axis as the shaft 25. An arc spring 28 is fixedly connected between the lever 26 and the inner side of the connection block 24. A cross column 215 is clamped on the inner side of the bracket 3, and the cross section of the cross column 215 is trapezoidal. By replacing the clamped cross column 215 with a cross column 215 with a longer or shorter trapezoidal slope, the distance at which the lever 26 contacts the slope can be changed, and the distance at which the slide plate 29 is pushed by the lever 26 can be adjusted, thereby adjusting the fixed distance of the fixed-distance drilling of the pistol drill 1.The inner side of the bracket 3 is fixedly connected to the limit block 216, and the inner side of the limit block 216 is hinged with a hinge plate 217. After the drilling is completed, pick up the pistol drill 1, and the compressed spring 23 will push the slider 22 to drive the support plate 21 to reset. When the slide plate 29 is toggled, the toggle groove 210 will contact the inclined surface of the trapezoidal block 218, forcing the trapezoidal block 218 to drive the hinge plate 217 to rotate. The top surface of the hinge plate 217 is fixedly connected to the trapezoidal block 218. When the trapezoidal When block 218 overlaps with the next toggle slot 210, the torsion spring 219 will push the hinge plate 217 to make the trapezoidal block 218 embedded in the toggle slot 210, and the vertical surface of the trapezoidal block 218 will contact the inner side of the toggle slot 210. At the same time, the right side of the limit block 216 will contact the hinge plate 217 and limit it, so that the trapezoidal block 218 can limit the slide plate 29 in one direction. A torsion spring 219 is fixedly connected between the hinge plate 217 and the limit block 216.

[0026] Based on the above embodiment, when in use, first insert the hardware such as the power installation plate that needs to be punched between the clamping plate 213 and the placement plate 220, tighten the bolt 214 to clamp the clamping plate 213 and the placement plate 220 to clamp the installation plate for power installation, and then align the pistol drill 1 with the through hole of the support plate 21, and press the pistol drill 1 against the support plate 21 downward, so that the support plate 21 drives the connecting block 24 to slide downward, and at the same time, the support plate 21 will drive the slider 22 to press the spring 1 23, and when the connecting block 24 slides downward, it will drive the lever 26 to move downward together through the shaft rod 25, and the lever 26 will gradually insert into the toggle groove 210, and will also resist the inclined part of the cross column 215, thereby forcing the lever 26 to rotate about the axis of the shaft rod 25, and then the lever 26 drives the slide plate 29 to slide, and the slide plate 29 will drive the power installation plate clamped by the placement plate 220 to slide together, and when the lever 26 stops toggling, the pistol drill 1 The drill bit has not yet touched the power installation board, and the pistol drill 1 can be pushed downward to drill a hole in the installation board. After drilling, the pistol drill 1 is picked up, and the compressed spring 23 will push the slider 22 to drive the support plate 21 to reset. When the slide plate 29 is toggled, the toggle groove 210 will contact the inclined surface of the trapezoidal block 218, and the trapezoidal block 218 will drive the hinge plate 217 to rotate. When the trapezoidal block 218 coincides with the next toggle groove 210 opened, the torsion spring 219 will push The movable hinge plate 217 causes the trapezoidal block 218 to be embedded in the toggle groove 210, and the vertical surface of the trapezoidal block 218 will abut against the inner side of the toggle groove 210. At the same time, the right side of the limit block 216 will abut against the hinge plate 217 and limit it, thereby causing the trapezoidal block 218 to limit the slide plate 29 in one direction. By repeatedly controlling the pistol drill 1 to press the support plate 21 downward, the toggle rod 26 repeatedly toggle the slide plate 29, thereby realizing unidirectional and fixed-distance drilling of the power installation plate.

[0027] At the same time, the clamped cross column 215 can be replaced with a cross column 215 with a longer trapezoidal slope or a shorter slope to change the distance at which the lever 26 contacts the slope, and then the distance at which the slide plate 29 is moved by the lever 26 can be adjusted, and then the fixed distance of the fixed-distance drilling of the pistol drill 1 can be adjusted, so as to adapt to more power installation requirements.
