Description

Technical Field

[0001] The utility model relates to the technical field of hole opening devices, in particular to a hole opening device for preventing workpiece deviation. Background Art

[0002] A hole punch is a tool or device used to create holes or apertures in various materials. These holes can be round, square or other shapes.

[0003] Publication No. CN218253044U discloses a hole-opening device with adjustable hole size, which belongs to the field of cable technology. It mainly solves the problem that it is difficult to adjust the hole size of the current hole-opening device, and proposes the following technical solution. It includes a workbench, a vertical frame, a hydraulic cylinder and a drive motor. The vertical frame is fixedly connected to the upper end surface of the workbench, the hydraulic cylinder is fixedly installed on the upper end of the vertical frame, the drive motor is fixedly connected to the output end of the hydraulic cylinder, and a conical hole-opening head is fixedly installed on the output end of the drive motor. A regulating mechanism is connected between the vertical frame and the drive motor. The utility model sets a regulating mechanism, so that the height of the entire control switch can be appropriately adjusted, so that the descending height of the conical hole-opening head can be adjusted. When the touch plate contacts the control switch, the entire drive motor will be turned off, thereby stopping the drilling; so that the entire hole-opening device can better control the size of the hole. Although this type of hole opening device can adjust the size of the hole, it is lacking in preventing the workpiece from shifting. Since this type of hole opening device does not have an adjustment structure, when the workpiece needs to be adjusted after it is fixed, the workpiece can only be taken out of the fixed structure and then fixed. During this process, the workpiece may not be aligned, resulting in the hole position shifting during drilling. Utility Model Content

[0027] Working principle: when it is necessary to punch a hole in the workpiece, first pull the handle 16 outward, the handle 16 will drive the clamping plate 15 to slide on the surface of the placement plate 12, and will also slide on the surface of the slide bar 13. After the clamping plate 15 slides open, place the workpiece on the placement plate 12. At this time, release the handle 16, and the clamping plate 15 will be pulled back by the tension of the tension spring 14, so that the workpiece is clamped in the placement plate 12 through the clamping plate 15. After the workpiece is fixed, when it is necessary to adjust the workpiece, just turn on the motor B9, the motor B9 will drive the screw rod 10 to rotate, and the screw rod 10 will drive the placement plate 12 to move horizontally through the connecting block 11 when rotating, so that the workpiece moves horizontally. After adjusting the workpiece, turn on the cylinder 2, the cylinder 2 will drive the support plate 3 to move downward, and the support plate 3 will drive the motor A5 to move downward, so that the workpiece is punched through the motor A5 and the drill bit 7. The motor B9, the connecting plate 8, the connecting block 11, the screw rod 10, and the placement plate 1 2. The clamping plate 15, the spring and the sliding rod 13 facilitate the adjustment of the fixed workpiece, avoiding the need to remove the workpiece from the fixed structure when adjusting the workpiece, thereby preventing the hole position from shifting. When the positioning plate 19 needs to be replaced, only the inserting strip 17 needs to be rotated. After the inserting strip 17 is rotated out of the placement plate 12, the inserting strip 17 is pulled out of the fixing hole 20 and the positioning plate 19 is taken out of the placement groove 18, and then different types of positioning plates 19 are placed in the placement groove 18, and then the inserting strip 17 is inserted into the fixing hole 20, and then the inserting strip 17 is fixed to the placement plate 12 through the thread. After the inserting strip 17 is fixed, the replacement of the positioning plate 19 can be completed. The positioning plate 19, the positioning hole 21, the placement groove 18, the inserting strip 17 and the fixing hole 20 facilitate the positioning of the workpiece and also facilitate the replacement of different types of positioning plates 19 according to the punching requirements, thereby improving the adaptability of the punching device.
